Firefox 20: Download for anniversary - Mozilla celebrates 15th birthday

Firefox 20 is now available for download. Mozilla announces the release of the new version of the open-source browser on time: The Foundation is currently celebrating 15 years of existence. The new browser is intended to convince users with extended privacy features. This allows web surfers to access the privacy mode without starting a new session. Browser reboots including loss of active tabs to open web pages in private mode are history.


The switch between and the parallel operation of normal and private tabs are possible on desktop computers (of course also laptops) and on Android devices. To do this, right-click on a link or select the menu item "Open the link in a new private browser window". This new feature lets you, for example, check multiple email accounts during a session without having to use multiple browsers or Firefox instances as before.


The new Firefox 20 Download Manager also allows you to easily track downloaded files without having to launch a new browser window. The Android version also allows you to create and organize shortcuts to favorites on the homepage. As of now, Firefox is now running on devices equipped with ARMv6 processors. Firefox can also be used on older tablets.


Firefox 20 is also interesting for developers. With "getUserMedia" it is possible to write code, which can access multi-media devices such as microphones and webcams of the users. With the "Developer Toolbox" and new "Canvas Blend Modes" there are other useful tools available. The Mozilla project started by March 31, 1998 with the release of the source code from the Netscape Navigator. The time is usually the birth time of Firefox. You can download Firefox 20 on the official website of the manufacturer. It is also worth looking into our comprehensive and always up-to-date download portal.


Improve wireless reception

Almost every Internet provider provides its customer with online connection a WLAN-enabled router. Depending on how long you contract with the provider, you get the device even free. Hardly a user wants to renounce the comfortable wireless connection to the Internet at home. Apart from this, more and more networkable devices are found in the trade, which can only be integrated via WLAN into the home network. This includes, among other things, all modern smartphones, tablets, e-book readers, numerous web radios and wireless IP cameras. Smaller, more accustomed devices can often use WLAN only with very good reception conditions. In the mobile devices, the WLAN antennas are usually less effective than the much larger notebooks.


Receiving problems


Smartphone and tablet users depend on stable WLAN reception as they often change their location. Who wants to go with his mobile device from the kitchen into the living room to quickly look up a cooking recipe online, because in the kitchen the WLAN reception is too weak? The same applies to downloading music, retrieving movies, or updating the installed app. Even if the mobile device also has UMTS reception, bandwidth-intensive downloads are better handled via wireless LAN. In contrast to most UMTS tariffs, these connections are not limited to a certain transmission volume. The problem: WLAN can not be replaced easily by the alternative transmission types, such as network cable or the Powerline technology. Neither smartphones nor tablets have a network cable connection.


WLAN-n instead of WLAN-g


And who wants to hang his pretty, mobile little one already on an ugly, bulky LAN cable? So how can you improve the WLAN reception in your own house or apartment so that mobile devices can be used in all rooms?


Extensions by radio and power


The first step leads directly to the WLAN router. Here you should first check which WLAN standard the device supports. If it is a WLAN router according to the 802.11g standard, this transmits with a maximum transmission rate of 54 MBit / s. Although still many current devices are equipped with WLAN g adapters, this standard is already out of date. It is gradually being replaced by the much improved 802.11n standard (WLAN-n). WLAN-n offers significantly higher transmission rates depending on the hardware used, 150, 300 or even 450 MBit / s. The n-standard also uses various intelligent transmission techniques which can be used to bridge even unfavorable connecting distances. The first step for a better wireless network is thus: Replace the old WLAN-g router with a WLAN-n-pendant. For the exchange the access data for the Internet connection are necessary. In addition, one should consider a WLAN-n-Router with integrated modem and do not have an additional device. If the new router is set up, all WLAN devices at home must be reconnected to the WLAN of the new router. At certain distances or when several radio barriers, such as walls or floor ceilings, a WLAN-n router quickly reaches the limit of its range. Thus, a connection from the WLAN router in the basement to the notebook or web radio in another floor must overcome at least two storeys and possibly one or two walls. Depending on the structural conditions, connection problems may occur.


Powerline with access point


In such a case, a so-called WLAN repeater can be used. These devices extend the wireless network of a WLAN router. To do this, you place the repeater approximately halfway between the WLAN router and the terminal. In the example mentioned, this would be the ground floor, which is located halfway between basement and first floor. The repeater then establishes as a conventional WLAN client a connection to the WLAN router. The WLAN client on the first floor in turn connects to the WLAN repeater on the ground floor. In this way, the repeater routes all the data from the WLAN router in the basement to the device on the first floor and vice versa. Another way to bring WLAN reception into badly accessible rooms is a powerline adapter with integrated WLAN. The network connection is distributed by the router over the power supply. For this purpose, a LAN port on the router must first be connected to a conventional Powerline adapter, which in turn is plugged into a socket near the router. The second Powerline adapter is equipped with a WLAN access point and to any outlet Within the apartment or the house. After switching on, the connection to the Powerline adapter 1 and thus to the router is established. Any WLAN device (such as smartphones or notebooks) that connects to the WLAN of the Powerline adapter 2 is then automatically connected to the router via the power supply and the adapter 1.


Also here it is possible to take the WLAN Powerline adapter always in the desired room. Similar to the repeater, it is important that the connection of the two Powerline adapters via the power supply is stable enough. Which sockets-combinations work for the data transmission depends very much on the individual power cabling in the home or in the house.


An interesting alternative to the WLAN repeater is the Powerline adapter with an integrated access point. As a rule, such devices are offered as kits with a Powerline adapter for the connection to the router. While a WLAN repeater connects to the router via WLAN, The Powerline adapter connects to the router via the power cable installed in the house or in the apartment. The second Powerline adapter included in the kit is connected to a network port (LAN port) of the router and plugged into a free socket as far as possible Near the router. The connection between the conventional Powerline adapter and the router is done via network cable. In the second step, the Powerline adapter with WLAN option is plugged into a socket in the home or in the house. It connects via the power supply to the router and establishes a WLAN connection. The Powerline adapter makes an encrypted WLAN connection with the terminal easily with WPS at the touch of a button.


The devolo dLAN 200 AV Wireless N is an example. In addition to the integrated WLAN access point, the device also offers three Ethernet ports for connecting other devices via network cable. This makes it possible to connect network-capable Blu-ray players, media players, game consoles, TVs, printers or network hard disks to the home network (router) over the power network

A wireless network access is highly convenient as long as it is distributed throughout the household. However, every house or apartment situation is a little different and so depending on the constructional circumstances, there are always places that the wireless network of the wireless router simply does not reach or where it is much too weak.Here can be a WLAN or radio- Repeaters help: The device bridges unfavorable connection distances and thus ensures a largely stable supply even in places with poor connection. The practical feature of WLAN repeaters: The position is flexible and can be connected in principle to any socket in the house or in the home. It is important, however, that the repeater itself can always establish a sufficiently stable connection to the WLAN router. Once the device has been configured, it can be used in other places in the household as required. A repeater must be plugged into any outlet at half-way to the power supply. Afterwards, you set up a WLAN connection between the repeater and the router by setup wizard. The repeater behaves like a conventional wireless device against the router. With its second wireless module, the repeater then - similar to the WLAN router - stretches its own WLAN network. It offers all receivers within range a stable access to the home network and access to the Internet via the router.


In many households there are routers with the outdated WLAN-g standard and a maximum transmission rate of 54 MBit / s. If you want to improve the range and transmission power of your WLAN, this router should replace it with a current WLAN-n (802.11n). This is the currently most powerful WLAN standard, with transmission rates of 150, 300 or 450 MBit / s reached. The rates depend on the number of integrated transmit and receive antennas. However, the maximum values ​​given here can only be achieved if the connected terminal supports WLAN-n.


Routers with WLAN-n use several transmit and receive antennas and transmit data on several parallel radio channels. This is referred to as "multiple input / multiple output" or "multiple data input / multiple data output" (MIMO). Intelligent antenna technology from WLAN-n can also send and receive data in a time-delayed manner. This way, even the signals that reflect on walls or obstacles can be exploited. The practice shows that most WLAN-n-capable routers also contribute to an improvement in the range even if the connected WLAN client is only equipped with a WLAN-g adapter. Nevertheless, a WLAN-n-router can not cause miracles. Some connections can not be bridged by a powerful WLAN-n device due to their length or specific radio barriers.

The five best netbooks in the test

Netbooks are particularly compact laptops that come with a 10 or 11 inch display. Thanks to the limitations in system performance, they are significantly cheaper than subnotebooks at prices of around 250 Euros. For surfing, e-mailing and for Word, Excel and Co., however, your performance is sufficient.


Buying advice: The right Netbook


Netbooks are less hip than tablets, but they have the real keyboard and - as long as there is no Windows 8 - the full-fledged operating system on which any software can be installed.


Place 1: Asus EeePC 1225B (90 points)


The selection of your netbook should make you primarily dependent on its display size. Netbooks with a 10.1 inch display are particularly suitable as a mobile second device. The larger netbooks with 11.6 inch large display, however, can also be considered as a full-featured notebook - among other things because the larger display has a better keyboard.


Picture gallery


The Asus EeePC 1225B scratches in almost every respect at the notebook class. The display is 11.6 inches in size, the memory measures a whopping 4 GB and also the weight of 1.44 kg is above the netbook average. The Asus already has USB 3.0.


Rank 2: Acer Aspire One 722 (82 points)


Test: Asus EeePC 1225B


The combination of AMD-E-450 processor and Radeon HD6320 graphics chip delivers rich performance. The generously dimensioned battery nevertheless allows 8-10 hours of operation away from the socket. The mosaics, however, do not convince. The Asus netbook costs around 430 euros.


Similar to the Asus, the Acer Aspire One 722 is one of the larger and more powerful netbooks. Its 11.6-inch display is resolved with 1366 * 768 pixels. Despite the larger display, the Acer weighs only 1.35 kg.


Review: Acer Aspire One 722


The two USB 2.0 ports are equipped with a VGA and HDMI port, which allows external monitors or projectors to be connected flexibly. The Acer Aspire One 722 is priced at 300 euros.


The now only isolated Samsung Netbook is synonymous with the Toshiba device. The better placement is due to the cheaper price. The NC10-JP05 weighs only 1.2 kg, and thanks to its energy-saving Intel Atom N455 processor, it has an excellent battery life of 7 hours and more. It also has an excellent keyboard and works great.


Review: Samsung NC10-JP05


The 10.1 inch display is rather low resolution with 1024 * 600 pixels. Especially when surfing the web, the 600 pixels make a negative impression, because they have to scroll on almost all web pages. The NC10-JP05 costs around 280 euros.


Toshiba's NB550D-11D is equipped with a modern C-60 processor and a powerful Radeon HD6290 graphics chip. This tandem easily plays HD video - supported by built-in Harman / Kardon speakers that provide superior sound.


Place 3: Samsung NC10-JP05 (80 points)


Review: Toshiba NB550D-11D


In view of the good system performance, it is regrettable that the display resolves with 1024 * 600 pixels and does not render HD videos in their native resolution. Users who know how to write a machine are hardly happy with the Toshiba keyboard. Too small keys can lead to frequent typing errors. The Toshiba costs from 320 euros.


4th place: Toshiba NB550D-11D (80 points)


With 1280 * 720 pixels, the 10.1 inch display of the Acer Aspire One 522 is extraordinarily high resolution. This is good for fans of HD videos who are looking forward to playing their footage in native resolution. The increased resolution also causes text to appear smaller. This can only be partially compensated for by the Windows 7 system settings.


Review: Acer Aspire One 522


The combination of an AMD C-50 processor and a Radeon graphics chip provides a lot of power. 1 GB of RAM is sufficient for Windows 7. The battery life is limited by 3.5-6 h. The Acer Aspire One 522 is priced at € 275.


Place 5: Acer Aspire One 522 (75 points)


Conclusion


Of the netbooks with 11.6 inch display makes the Asus the most fun. It is also the most expensive device in the test. Saves money on the comfort of a lush display and a large keyboard, so you're more likely to use the Acer Aspire One 722.


The fact that the netbooks of Samsung and Toshiba are now only managed by few traders is regrettable. The Samsung is the ideal, highly mobile second-hand device for multiples, while the similarly rated Toshiba film fans satisfies.


Both the Acer Aspire One 522 is also very successful. If you are running your netbook in the vicinity of the power outlet and can not afford long battery life, you should look at this netbook.


DIGIBIT PL 500 & PW 500: Powerline adapter from Telestar

If the WLAN connection reaches its limits because of too thick walls or too long distances, Powerline can help out. Here, all types of data are distributed over the home or residential power grid. For example, videos, music and photos will find their way from the PC to the TV. This also allows you to access the Internet without extensive installation work. The Telestar Powerline solution is designed to deliver data at speeds up to 500 megabits per second.


The DIGIBIT PL 500 is a pure wire-based solution. An adapter of the model series feeds the respective data into the power supply and can be placed, for example, directly at the router. The two are connected using a standard Ethernet cable. The data from the Internet then migrate from there through the power supply to further adapters, which are likewise connected by Ethernet with the terminals such as computer or television. This means that communication is already established, and data transport is possible.


The adapter DIGIBIT PW 500 supplements the pure wire-based connection with WLAN functionality. The data is also supplied via the power supply to the socket into which the adapter has been plugged. From there, however, the route continues wireless, since the DIGIBIT PW 500 can pass the data via WLAN technology and thus can also supply mobile devices such as tablet PCs or smartphones.


Sat to IP: Satellite television over the network


The adapters are available from May. The DIGIBIT PL 500 costs around 80 euros per piece, the DIGIBIT PW 500 is available for 110 euros.


Windows 10 Wallpaper: Official Hero background in the video

In a new video, Microsoft shows the Hero wallpaper for Windows 10, and how it was created. The story of this article presents the official background image as a screenshot from the video, which we show you in this message. We see on the right the Windows Windows logo introduced with Windows 8, which is illuminated from the back. Transparency, multiple light cones and smoke create a futuristic, cool atmosphere.


Windows 10 Hero Desktop Image Behind the Scenes


Microsoft has built the motif - as documented in the video - real, fog machine and lighting switched on and photographed. Photoshop or comparable professional image processing programs appeared to be used afterwards.


Picture gallery


Responsible for the futuristic design of the Windows 10 Hero Wallpapers is Bradley Munkowitz. This already created the title screen of the Kinobil Tron: Legacy (2010) and the graphical user interfaces of the computer systems in the Tom Cruise strip Oblivion (2013)


Windows 10 will be released on July 29th and will be installed on more than one billion devices within the first three years. Clearly, Microsoft does not simply leave the background image to chance or a whim of a developer: Windows wallpaper have a tradition! Many users leave the default background image after the Windows installation process


The result: Every Windows release is clearly identifiable - a grassy hill under a slightly cloudy and blue sky probably stands for almost all computer users automatically for Windows XP. Later motifs followed, which many users still remember today. Look at the following gallery


With Vista it is a yellowish-green interplay of curved lines, light cones and transparency effects, which supported the new Aero-Glass design. Windows 7 comes in the basic setting with a similar but much less playful motif with bright blue tones, a slightly shimmering light source and few curved lines in white (plus a delicate plant). On other systems, the standard wallpaper of Windows 7 can also be changed as a basic setting after the setup in 30 minutes. The most popular is probably the architecture or landscaped landscapes that provided the right motifs.


In Windows 8 it was only a sunflower in close-up, except for the one-color start screen, and an orange motif at 8.1 that contained cubic shapes analogous to the new live tiles.


Loewe Type 46 LED 200 DR +

To put an end to practical solutions, the traditional innovator Loewe invests a lot of money, but also expects the latter from his customers. You can still get the best recording solution – now with multi-room video as well.


Two steps ahead


Recommended viewing distance [at least]


Conclusion


Loewe is an old hare for many of the most sought-after equipment specialties. Tuner extensions, recording functions, networking, even ecological thinking were introduced many years ago. With no other manufacturer is a TV as good as the customer tunable as with Loewe. If you just want to watch TV, buy a Art 46 for 3,000 euros.


Satellite tuners, recording functions and WLAN cost extra, and are installed directly by the dealer before setting up and calibrating the unit. The selection of housing colors, installation variants and perfectly integrable sound solutions is also enormous. We opted for the maximum equipment in high-gloss black.


Every good TV has multi-tuner, CI-Plus and a recording function. How great the differences in basic functionality are, however, is shown in the application. Loewe is giving the Arts directly two copies of each recipient so that the user can simultaneously watch a program and record another.


The hard disk is installed. Competitors are frightened by the fact that this expensive component runs through the value chain and makes the TV considerably more expensive.


If you activate the timer recording or the time-delayed television, you can quickly determine how professional everything has been implemented. In addition to digital TV, no competitor's device can record analogue sources, is so fast in the pause function (when recording continues), has editing functions or recordings from the Timeshift buffer.


Optimal settings


Color: softImage + Active: offAutoDimm Room: einVBD +: fromDNC: fromDMM: on


Lots are options such as copying to an external hard disk or - all-new - forwarding the archive to the network. Thus, a recording or the current program can be viewed on another networked Loewe TV of the latest generation. If you want to use both Sky and HD-Plus satellite at the same time, it is welcome that there are two module slots for CIPlus.


The subject of multimedia content also has a long development tradition at Loewe. It has focused on high-quality music and video streaming content, and the colorful Internet App TV, which Philips, Samsung, Panasonic and Sony have individually introduced, neglects


Now, the manufacturer is up-to-date by means of a cooperation and has even been able to profile itself through the fastest implementation of an innovation. Loewe was the first manufacturer to put a new series of TVs into the test lab, where HbbTV works flawlessly.


Loewe is not involved in the production of LCD panels and was only able to react late to the 3D boom, too late for the current generation of devices. In the Art series, there is no contrast glass that reduces reflections and increases light efficiency.


Testimonial


Loewe Art 46 LED 200 DR +


From € 3.500, www.loewe.de


+ Best recording solution integrated + many individual device variants + CI-Plus available twice - few options for calibration prompts


Overall rating: very good 82%


Price / Performance: good


The fast 100 Hz panel is exposed 200 times per second by flashing the edge LEDs, which shows sharp contours during movements. The electronics respond more elegantly to critical object movements than their predecessors.


Otherwise, little has changed in image philosophy. All the parameters of the image control are largely automated, there are no cryptic image enhancement methods. Loewe's middle class scores with a very pleasant to look at the image.


The sound is Loewe's hobby, but the volume lacks the volume to keep up with his predecessors in the bass range. Language, atmosphere and low-bass music sound precise and unadulterated.


Loewe's new type TVs are waiting for a top price for a Loewe-affair, but a high price for normal citizens.


TV: 3.2 m, PAL DVD: 2.8 m, HD: 1.9 m

DVB-C2 and DVB-T2: the future of digital television

The DVB standard has been providing the best services worldwide for more than 20 years. With it inseparably connected, the terms program diversity, high image quality and transmission stability.


The new DVB


But time does not stop. Especially in the past three years, the TV world has changed dramatically. High definition is now standard, interactive TV services are emerging, and mobile media access is experiencing rapid growth. Already with Ultra High Definition (UHD) announces the next evolutionary stage. It offers immense picture quality, but is also extremely data-hungry. All of these services are increasingly used for transport. This applies to the dispatch via antenna, mobile radio and cable. The question of the transmission efficiency of the networks is therefore becoming more urgent: if the networks lag behind other developments, they may turn out to be an innovation brake.


Politics pushes at


This is where the second generation of the DVB standard comes into play. The satellite reception has already implemented it in the course of the HDTV introduction long ago. For antenna and cable reception DVB-T2 and -C2, however, no need has yet been identified. In many countries, DVB-T2 is already in use such as the UK, Italy or, more recently, Austria. The young DVB-C2 standard was released in April 2010, but is nowhere in regular operation.


Hesitant decision


The reasons for the restraint against the DVB second version in the United States are complex. On the one hand, the assessments for its necessity are far apart. On the other hand, cable and antenna networks follow their own market conditions independently.


No jam in the cable


Antenna televisions are currently under discussion, involving the federal government, DVB-T network operators and mobile operators. The positions seem quite hard.


In its "Strategy Paper 2017", the Federal Network Agency shows that it would like to push the broadband expansion for the Internet in unison with Europe. It is responsible for the allocation of broadcasting frequencies. The precarious point: Among other things, it wants to provide the broadband mobile radio frequencies in the 700-megahertz range - and the so far uses the antenna television. 30% of the current DVB-T transmission capacity would be lost.


All about HEVC - High Efficiency Video Coding


When the request became known, violent discussions began. The most important network operator, the public-sector broadcaster ARD, takes the position - quite unpublically - with only fragmented information position. As a voice tube, the Deutsche TV platform is expressing in a current position paper that the frequencies for a change to DVB-T2 as well as for a longer period after that exist existentially for the antennensfernsehen


Jochen Mezger of the Institute of Radio Technology (IRT) agrees with video on request that the frequencies are at least necessary for the conversion. The reason: DVB-T and -T2 will be broadcast jointly ("simulcast operation") within a transitional time, since the new DVB versions also require new receivers. The parallel radiation should make the change more user-friendly.


At the latest, in the context of the frequency discussion, it would be high time for ARD and Kompagnon ZDF to press on the gas. But far from it: "There is still no decision by the ARD as to whether and, if so, when a change in the terrestrial distribution of its television programs should take place", was until recently the stereotypical information, which was valid for both transmitters

Just before the completion of this report, ARD and ZDF were finally announcing new developments - if again extremely timid. From 2017 onwards, they wanted to switch over to DVB-T2 successively.Support: To create the change, the 700 MHz frequencies are needed until at least 2020.


So there are still a few years ahead of DVB-T customers. What concrete innovations they expect, the public broadcasters are silent. Questions about high-definition transmissions or interference-free mobile TV reception remain unanswered. The channel KIKA and ZDFneo would be broadcast around the clock, according to the announcement.


Practice: Sat-to-IP - Satellite TV by network


Different opinions


Media broadcast as another DVB-T network operator is more concrete. The cornerstones here are HDTV and mobile TV reception. Area manager Bernd Heimermann sees the need to signal to consumers and politicians that the antenna technology remains technically on the ball and therefore has an existence right. In doing so, he also uses the much-discussed frequencies for the conversion phase.


Carine Lea Chardon from the Central Association of the Electrical Engineering and Electronics Industries (ZVEI) also considers a signal to the policy. It assumes that the federation of DVB-T network operators "wants a clear statement about DVB-T2". Ultimately, it is a matter of not wasting any frequency capacity.


Manufacturers without opinion


On the cable the conditions look different. There is currently no need to intervene in politics: there is no acute shortage of the "resource" frequency. However, the cable network operators must also operate with their transmission capacity. How do opinions differ widely? The largest network operator Kabel Deutschland GmbH (KDG) is expecting a further increase in the number of high-definition transmitters. According to Christoph Schaaf, Head of New Technologies, there are also ongoing Internet services such as Video on Demand in HD. And Ultra High Definition (UHD) looks as the next image quality level.


Ultra HD - The new generation of television


KDG wants to create space for such offers with DVB-C2. "We see this as a major innovation step," Schaaf points out. The KDG plays a pioneering role. Since June, the operator has been testing the new standard in Berlin, Hamburg and Munich. The results are consistently positive. "We want to get started," says Schaaf. He sees UHD as an opportunity. For both DVB-C2 and UHD, the TV viewer needs new receivers. It is now possible to jointly introduce both innovations.


Conclusion


The technology: DVB-C2 and -T2


If there were only one cable network operator, the new DVB standard would be introduced here so soon. But the competition is different. The second largest television network operator, Unitymedia Kabel BW, also sees the need for DVB-C2. "However, we do not have specific timetables for upgrading our networks to DVB-C2," says Daniel Hesselbarth, Director CPE & Product Innovations. Only when UHD is "large-scale available" is it possible to get started.


Reinhard Sauer from the Tele Columbus Group again doubts C2. It considers the Internet transmission as a solution for possible capacity bottlenecks. Until then, DVB-C would be sufficiently powerful. In addition to the large network operators, there are also many small providers in the United States. These have not yet been discussed on the subject.


The third large group in DVB-Bunde are the TV and box manufacturers. They consider the situation to be rather neutral. The credo is that the decision for or against the DVB secondary version is the responsibility of the network operators. Until then, keep with corresponding devices. Receivers for C2 and T2 would easily master the old standards. Sony is currently the only manufacturer to offer TV sets for DVB-C2. The number of antennas is larger because of the demand from other countries. the United States is, after all, a beneficiary.


DVB-T2 brings interference-free mobile TV reception and high definition. DVB-C2 is one of the pioneers of UHD. These are real value-added services for the TV viewer.


UHD is still low in popularity among consumers. This is likely to change soon. The requirements for DVB-T will also increase. Stable mobile TV reception is an important argument for aerial television, and Full HD certainly want the viewers soon. The public broadcasting corporations will therefore have to become more concrete soon. The introduction of DVB-C2 in the cable network, on the other hand, is likely to be inconsistent. It will start at the latest with the first UHD program, which starts the satellite competition. And then there is a pulling force.


The most important set-point for the second generation of DVB-C and -T is square amplitude modulation (QAM). It is a combination of the well-known amplitude and frequency modulation methods, which have already been used to broadcast or store analog video and audio signals. In this case, radioswaves are modified (modulated) in their amplitude (in graphic 1: "AM") or in their frequency (in graphic 1: "FM") so that they transmit a desired, "modulated" Signal ").


The modulated waves shown can, however, occupy only one state at a time-and thus also transmit only a single information. Thanks to QAM and digital language, however, numerous states and thus also a correspondingly large number of video and audio information can be transmitted at the same time. In DVB-T, there are 64 states (64 QAM), DVB-C creates 256 states (256 QAM).


DVB-T2 reaches 256, DVB-C2 1,024 QAM, which represents a clear increase in efficiency. For illustrative purposes, the cable network currently handles around five gigabits per second data rate. With C2, almost three gigabits would be added.


This corresponds to a capacity for 300 more HDTV stations. The lab photo shows such a 1,024-QAM diagram. Each gray area therein corresponds to a so-called symbol. The video and audio signal information is composed of them.


In order to be able to transmit a larger number of states simultaneously, not only highly developed modulators are required to generate and emit the signals. The correspondingly accurate signal transmission through the networks must also be possible so that the receivers receive the information without errors. The current infrastructure of the networks meets the requirements of the second DVB generation. The standard itself, however, still allows growth. Experimental has already been tested with 2.048 and 4.096 QAM.


For this purpose, glass fiber cables would then be required in order to achieve the correspondingly high precision during signal transport. DVB-T distribution seems currently inappropriate for such QAM levels.


Tips for online shopping: Secure shopping on the Internet

Many Internet shops adorn themselves with check seals that promote trust. But not everyone is trustworthy. For more information on trustworthy quality seals, please visit www.internet-guetesiegel.de


Tip 1: Check the critical seal


Pay by invoice if possible. And if the dealer refuses this option because you are initial customer, you prefer to pay the fees for an order cash on delivery. But check with the delivery whether the package contains the ordered goods before you pay.


Tip 2: Prepayment? In doubt, do not!


Good reviews from customers who have bought this item also like Stay cautiously with exuberant and overly positive reviews. Sometimes they are not from real customers, but from the online store itself. There are even agencies that write such false ratings against fees.


Tip 3: Read reviews with caution!


Serious traders always name their full company address in the imprint or under the entry "Contact": address, contact person, e-mail address, telephone and fax. If you are still unsure, call the dealer before placing your order.


Tip 4: Can you contact us?


For a dealer from abroad, the shipping costs can be expensive, the delivery takes longer and additional fees for example for customs charge. Order here only if you are looking for something that is not available in a shop based in the United States.


Virtually every trader cooperates with information services. Often, the customer does not know whether he only gets information about him or even passes data on the buying behavior. Look at the dealer's terms and conditions, and do not click the box where the merchant will ask for your permission to share your data.


The data transfer from your PC to the shop should be encrypted. You can see this by the symbol of the closed lock in your Internet program and on the Internet address. It must start with "https."


A serious shop does not leave its customers in doubt about the amount of shipping costs and does not name them until the end of the order. Also pay extra fees for certain payment methods such as PayPal.


Some online retailers do not send you a binding "order confirmation" but an "order confirmation". That makes a big difference. For an order confirmation, you will remain uncertain if and when the dealer delivers the goods until shipping is completed. Sometimes it takes weeks.


Some retailers exclude the return of jewelery and swimwear in their terms and conditions (GTC). This is not allowed. Read the terms before placing your order.


Type the name of the internet shop into a search engine along with words such as "fraud" or "trouble". Read what other customers say to the shop.

Test: Archicrypt Password Safe 6

The user saves login names, passwords and the associated web pages. New in version 6 are, in particular, automation functions, which are intended to facilitate the user’s handling. When logging on, the program promises, for example, to fill in and submit the login data automatically. This did not work in the test however incomplete.


Conclusion


With Firefox (8.0.1) there is an error message. With IE folds the login, but only with some sites like Facebook. For pages with changing login address (Flickr) or pop-up login fields (dropbox), nothing happens. The AES 256 tool is used for encryption. The key is password-protected or can be swapped to a stick.

Overall rating: satisfactory 60%


For the stick or the Internet, there are also mobile password safes. In the web, Archicrypt works together with Passwort-zentrale.de, with extra costs. The interface of the program is sometimes hackly, sometimes you do not see control panels, or the window bar is hidden, so the user can not move the program.

AVS Audio Converter Download

Music must be transportable nowadays. Users want to play them in the office on the computer, listen to them in the living room, take them on the mobile phone and transfer them to a mobile multimedia player. Often enough, the failure of the painful format barrier fails: the different devices usually support only a few formats – and usually not exactly what you use.


The AVS Audio Converter helps convert audio files from one format to another. The program is compatible with all major formats including MP3, WMA, WAV, M4A, AMR, OGG, MP2, FLAC or M4R. Before conversion, the AVS Audio Converter even offers to edit individual files in the program. It is possible to cut selected passages, insert foreign sounds or merge two files into one. If you want, a sound file can also add prepared audio effects.


Guide: 80 clever freeware tools


Two important functions are of particular interest to users. So the program can extract the audio track from online videos and save it as a stand-alone music file. Music can be released from rare live recordings - if they are available in video formats such as DVD, MPEG, MP4, AVI, DIVX, MOV, WMV, VOB, 3GP, RM and QT. The batch function is also widely used. It ensures that many marked files can be converted to a new format in one go.


RAW converter: ACD Systems ACDSee Pro 7 in the test

The surface is in dark gray tones. The division also offers hardly any surprises, so users can quickly find their way into ACDSee Pro 7.


Also interesting is


The four tabs "Manage", "View", "Develop" and "Edit" are self-explanatory. Under the fifth tab "365", the program offers cloud and other online services. In the administrator, users have the ability to view and edit IPTC and EXIF ​​metadata. The XMP, for example, used by Adobe or Corel does not support ACDSee Pro 7. In addition, the program allows you to combine them into albums or dynamic folders.


Conclusion


Practical: Images on the hard disk can be opened directly via the folder structure, an import is not necessary before. There is also a calendar view as well as the possibility to position or locate images on GPS maps. Super: Image evaluations, color markings and the addition to the quick selection succeed quickly by keyboard command


Like the competition, ACDSee scores with loss-free image processing - the original is not touched. Contrary to the competition, however, the changes do not only happen in the database, the program always creates a new JPEG image, which costs storage space. The constant asking if you want to save can be disabled.


Apart from that, ACDSee Pro 7 offers everything you need from a RAW converter: lighting, colors, sharpness, and noise, as well as falling lines and lens distortions. The latter, however, is not based on lens profiles, but only manually. This means much more work for wide angle photographers. After all, all settings can be saved and applied as profiles to other images.


However, the quality of the noise filter can not keep up with the competitors: Even color noise remains clearly visible, which otherwise all the test subjects cleanly calculate. Selective corrections are included on board. Similar to Lightroom, it works alternatively with a brush, as a straight or circular course. All development tools are available for selective correction.


However, masks created in the "Detail" category can not be further corrected in the category "Settings" - here users have to create their own mask for each category.


The export succeeds in all important formats, alternatively as a slideshow or on CD / DVD. Flickr, Facebook and Co are also on board. In terms of speed, ACDSee Pro 7 is in the lower midfield. The program loading time is about 8 s on the test computer, the change between images takes about 1 s - this is fast enough in any case. When exporting the 225 test photos to the JPEG format, the program did not take much time with 6:21 min.


ACDSee Pro 7 convinces with a logical operating concept and a complete toolbox. Small weaknesses are no problem at the current offer price of 65 euros.


Windows 9 Release: Pre-builds of Threshold with Microsoft partners

The Windows 9 release is expected for April 2017; the “Technology Preview” (test version) of Threshold will be released in autumn 2017. According to reports, Microsoft’s top partners have already received pre-release versions of Windows 9. As a source of these statements, informers from the well-known and respected IT and technology website Neowin.


Also interesting is


The authors argue that these references have already been successfully tested for their correctness. Thus, the delivered version of Windows 9 is still limited. According to the upcoming beta test version or "Technology Preview", some announced features are missing. Whether this is the new Windows 9 start menu, for example, is unknown.


This menu would surely be interesting for many Windows fans and worth a look in advance. Correspondingly, users are likely to rub their hands in various forums for upcoming leaks. But Neowin writes in the message to Windows 9 that the previously supplied partners fulfill many requirements and must adhere to security requirements. These requirements are intended to ensure that none of the supplied partner information or material can escape into the public.


How these settings look like and how they differ from previous Windows releases are unknown. A glance into the past is sufficient, however, to know that pre-leaks and downloads can never be completely excluded or prevented. Because not only the partners, but also insiders can be responsible for one or the other leak.


This is the case of the former Microsoft Senior Software Architect Alex Kibkalo. He was responsible for distributing the copy protection tool from Windows 8. He was sentenced to three months' imprisonment and a fine of $ 100 in June 2017.


The Microsoft partners could face high penalty penalties if the contract is not respected and thus a significantly higher - at least financially - damage. Also features in the pre-versions themselves are conceivable, which prevent an unauthorized distribution. We will keep you up to date.


Converts Kontonummer and BLZ reliably for SEPA conversion - IBAN Calculator - Tip 2

Many IBAN calculators add the leading zeros that you enter, resulting in ten digits. In combination with the bank code and the country code “DE”, the IBAN computer calculates the checksum, which can be used to identify typographical errors. Because banks may use calculation rules that deviate from this pattern, IBAN machines may produce invalid results. You should therefore look at your bank for IBAN and BIC.

Print from iPhone & iPad: How it works without AirPrint

IPhone and iPad have a sophisticated print function. However, this requires an AirPrint-compatible printer. We will show you how to upgrade each printer with a free add-on.


Picture gallery


In the name of AirPrint, Apple has christened a technology, which also allows the home mobile devices to print on network printers. To do this, they must be on the same network as the printer.


In the past few years, many printers have been published that are AirPrint compatible. If you have such a printer, it's fine. Simply unpack, connect, turn on and it is already found by Apple's mobile devices. The print function has Apple by the way in the "share" menu accommodated. It is available in all major applications, such as Mail and Safari.


Reading tip: printer in the test


The situation is somewhat less satisfactory if your printer is not AirPrint-compatible. Hardly any manufacturer has made the effort to retrofit older devices by means of a firmware update. Technically this would have been possible. With the help of programs available for Windows and OSX, you can make any printer AirPrint compatible. The printer is connected to the PC via USB or network. The software then opens an AirPrint interface through which the printer can be reached. This also works with several printers at the same time. Disadvantage: The PC or Mac must be switched on for printing.


Lesetipp: Increase WLAN range


How this works in practice we show you for Windows using the free software Netgear Genie. It also works perfectly if you do not use a router or other hardware from Netgear. Genius is also available for OSX. Here, however, we have also had very good experiences with the little Euro-expensive software Printopia, which offers some additional functions.


TP-Link Archer VR200v in the test

With TP-Link there is finally again a manufacturer, which offers a possible alternative to the market-dominant “all-in-one” router Fritzbox. The TP-Link Archer VR200v has integrated a VDSL2 modem. If necessary, the fourth LAN port in the router’s gigabit switch can also be used as a WAN port. Or you can use a surfstick on one of the two USB 2.0 hosts, where the mobile access can also be set up as a “backup Internet access”


TP-Link Archer VR200v


The USB ports of the TP-Link Archer VR200v can also be used as SMB, FTP, media or print server with external memory or USB printer. A connected USB memory (NTFS) can be read at almost 10 MB / s in the LAN. In operation as a DSL modem router, the device supports VLANs so that LAN ports and WLAN accesses can be arbitrarily "mapped" into virtual, separate subnets with their own network identification.


Phone calls


The Archer VR200v has integrated a DECT base station for up to six mobile phones and offers two ports for analog phones. The base station supports the DECT Eco mode. You can also enter several VoIP connections, which can be assigned to specific numbers or telephones via call rules. Convenient: An answering machine is available as well as call barring or call forwarding.


Weak Access Point


Although the dual-band capable access point of the TP-Link Archer VR200v transmits to 802.11ac, but only with a stream in the 5 GHz band and thus a link rate of a maximum of 433 Mbit / s. At the same time, we are able to achieve a net transfer rate of 215 Mbit / s in the test, but in the worst case the non-existent MIMO is noticeable in the 5 GHz band under worse conditions.


Apparently, TP-Link also saves the DFS certification and can therefore only use channels 36 to 48. An online help is searched in the completely Germanized user interface of the router unfortunately in vain, and also firmware updates have to be carried out by hand. The power consumption of the router is only around 9 watts.


Despite the gritty WLAN equipment and minor flaws, TP-Links convinced us of VoIP-capable VDSL modem router Archer VR200v because of its extensive functionality and equipment.

Philips Fidelio B5 in the test

Philips Fidelio B5


The Fidelio B5 from Philips not only scores with the sleek and elegant design, but also convinces with two detachable loudspeakers (left and right). The main loudspeaker is shortened, but the wireless loudspeakers can be positioned to the left and right behind the listener, and as a result, they provide the surround sound as required by the manufacturer.


Conclusion


In the Praxistest, the Philips Fidelio B5's loudspeaker system was working perfectly: the rear speakers can be dismantled by hand and placed in the room thanks to their own battery. At first they are a bit too loud as they are still set to the level of the soundbars, but they can also be adjusted to the appropriate volume by remote control.


All in all, the Philips Fidelio B5 creates such an impressive space and, in a few simple steps, a surround system for the cinema night. That also changes the sound stage of the main loudspeaker, is clear, but the positive effect of the rear speakers can be a problem.


The Fidelio B5 liked us especially in the music mode. Here the voices are clear and easy to understand. The Soundbar provides both live and live music, as well as other music, to the listener.


The Fidelio B5 convinces both in the bass range and in the treble. Above all, the live concert of Toto on Blu-ray was fun in the listening test: The subtleties of the rattles came discreetly to the fore, and the drums were well perceptible without overlaying the rest of the music. As a wireless connectivity, Philips offers its customers near-field communications (NFC). The pairing works quickly and is confirmed by a beep. After that, there is hardly anything to complain about.


We can not recommend the Philips preset film mode. It produces an unattractive and above all very artificial echo, and also the tonal changes of the source material are clearly heard. Our tip: Enjoy the Philips Fidelio B5 soundbar in the music mode!


The Denon AVR-1911

Denon specks: The reduction to the essentials in the connections should benefit sound and operation. As a result, the AVR-1911 loses very much in the equipment rating, but it can keep up with the sound.


Simplify your Life


The last few years there has been an explosion of connections and equipment. Sometimes the feeling pushed, not the reason, but only the free space on the receiver back would determine the connection circumference. This has not only caused stress among users, who sometimes lost sight of the connections and configuration options.


Open for new


The developers, on the other hand, had to solve conflicts between the best possible image and sound processing in a small space. The best quality requires the shortest possible paths for the sensitive audio and video signals. In addition, unnecessary features are a burden on the budget and are also detrimental to the quality of playback.


Connections


Because HDMI is more and more than standard for picture and sound transmission enforces - one can with HDMI 1.4a over the cable to the TV device also still the television sound to the receiver direct - have the Japanese with the AVR-1911 largely on analog video inputs and outputs As well as audio rec-out jacks.


The layman already looks better at the clear connections and should as a rule miss anything, if he does not want to connect an analogue au-dio recording device. After all, the receiver can scale analog video signals with a 10-bit ABT 1030 video processor and convert it from half to full-screen. Power max 1080p for all image sources. Video menus via HDMI also simplify the handling of the simple small AV machine.


In terms of new media, Denon showed a great deal. For memory sticks with WMA, AAC or MP3 files, the developers easily installed on the front panel a USB input. This is also an iPod or iPhone with the original USB adapter cable directly connect. For those who like it more luxuriously, Denon still offers the ASD series of docks, which, among other things, enable image output via S-video output.


In terms of sound, Denon has achieved a harmonious concept as well as the equipment. The AVR-1911 is not a receiver of the Extreme. More than top performance in single disciplines, his playfulness is characterized by a musicality that is difficult to describe but easy to feel.


Closing your eyes gains the impression of listening to real musicians - much more intensively than with the devices of the competition. This makes its stereo performance over the analog inputs, when the album "Scratch my Back" by Peter Gabriel sounds, to an experience.


Denon AVR-1911, € 500


+ Natural sound colors + voluminous bass + front USB- few connectivity options


In the surround sound the basic virtues of the Denon were preserved: Thus voices sounded quite natural and the bass possessed the necessary kick. The particularly realistic reproduction of the space contributes to the overall impression.


With this receiver, live concerts are just as much fun as action films whose special effects have been benefiting from the rich, powerful bass of the AVR-1911. The change from 5.1 DVDs to native HD sound from the Blu-ray Disc brought an even finer resolution and solved the sound even more freely from the speakers. So the sound of the "Ghost Story" animation film came extremely long and sweeping.


Bottom line you can expect from a 500-Euro receiver in terms of sound. As far as equipment is concerned, in part.


5 x HDMI, 1 x USB Type A, 1 x YUV Component


Amazon: Higher prices for Apple users are "Schmarrn"

In an interview with the Rheinische Post, Ralf Kleber, head of Amazon the United States, said, among other things, the allegations that the company would display a different price to customers depending on the user device. The reason for this was a test of the TV broadcast “Marktcheck” of the Südwestrundfunk (SWR), according to which owners of Apple devices may have to pay a higher price for Amazon products than other users. In the case of a washing machine on a iPad was shown a price 10 euros higher than on a PC. According to Kleber, this is “absolute rubbish.”


However, what adhesives confirmed were often changing prices - but these are valid for all users of Amazon: "If we feel that the customer is developing a new market price, and that can be with some products several times a day, we react to it . Prices go up and down - but we tell the customer. And all at the same time. What is not there is different prices for the same product on different end devices. "According to SWR, the price of a camera changed within three days about 275 times, in the case of another camera the price changed in the same Period by almost 1,000 euros.


Lesetipp: Amazon flash offers of the day


If the utterances of glue correspond to the reality, it would remain to clarify how the SWR could show a different price for the mentioned washing machine. Price adjustments that were not displayed on one of the devices used, for example, due to settings for the caching of online content (browser cache), are conceivable. However, this is now difficult to find.


The SWR reported not only according to access device supposed price differences at Amazon and frequent fluctuations of same also over influences of the surfing behavior. However, they concerned other online retailers. Specifically, it was about the provider "lensbest", which when viewing the web site different prices than when the user comes through a search engine ad on the product page. We could indeed reproduce this behavior. As mentioned in the previous article on pc-magazin.de, this approach (dynamic pricing) is, however, completely legal. Customers only need to be aware of this.

Intranet: Checking the company network for security itself - How it works

Check Intranet for security itself


Network Inventory and Analyze


The realization that firewalls help to evaluate and limit outbound and incoming traffic is not new. But even traffic, which does not leave its own network or does not come from the outside, can create very own dangers. Have you ever thought about which devices are communicating with each other within a company network? Even in the larger dental practice around the corner, you often find a smart TV in the entrance area, the coffee machines connected to the network (announces when it is time to decalcify), file and database servers, PCs for data collection and scheduling, network printers and Maybe a meeting room with WLAN-enabled beamer. Added to this is the WLAN hotspot, so that the practical staff can work with the notebook.


In addition, unauthorized devices are often found by employees (such as WLAN routers) or simply forgotten hardware such as obsolete laser printers, access points or unsafe EC card terminals. These should be made visible, analyzed in detail and, if necessary, shut down.


A very good tool to get an overview of all devices active in the network is OpenVAS. The security and vulnerability scanner can be used to tester individual computers for deployed services and even perform penetration tests. If you call OpenVAS on a whole subnet, the scanner tries to contact and analyze all IP addresses in typically five parallel processes. OpenVAS usually identifies operating systems correctly, but in individual cases, it is necessary to check whether a detected Linux system with a web server and directory release is the SMART TV in the meeting room or the departmental NAS


For this reason, it is advisable not only to scan a complete subnet with OpenVAS, but also to scan inactive devices and scan them for activities. A good starting point for this is the lease tables of the DHCP server. If the ISC DHCP server is running on a typical Linux system, a look in the file /var/lib/dhcp/dhcpd.leases usually shows the currently assigned IP-MAC address assignments. Since this is a pure text format, it is easy to match the IP addresses that have already been scanned with OpenVAS. Of course you will not find devices that are connected to fixed IP addresses. However, these can usually be detected via broadcasts, which also do not require the switch and network card to support the promiscuous mode, ie forward all packets, not even for the listening device. For interception, the graphical interface is provided with a Wireshark, which can already be used in live operation, or for batch processing tcpdump, which can also be started with a filter.


In particular, if you want to broadcast broadcasts for several days on the Linux server, which offers, for example, DHCP and other services, tcpdump is practical. The entire recording can then be copied to another machine and analyzed there (with Wireshark, for example).


Nikon D5: All details for the release of the DSLR-Topmodell

The Nikon D5 with its release as a new top model the D4s from the throne of the DSLR portfolio of Nikon. On Tuesday the professional SLR camera was presented at the CES 2017 in Las Vegas – in March 2017 the full-format DSLR is to come onto the market. After the rumors, we will summarize all the innovations and technical facts about the Nikon D4.


Upgrade for the autofocus


In the D5 Nikon integrates the new AF system Multi-CAM 20K with TTL phase detection. It offers a total of 153 measurement fields and 99 cross sensors. 55 auto-focus points can now be selected manually. The AF sensitivity is up to -4 LW (ISO 100).


Support for 4K video


Enhanced, the Nikon D5 also shows at the serial screen speed. The DSLR now provides up to 12 frames per second for exposure metering and AF tracking, or 14 frames per second with a high-fledged mirror. The buffer memory is sufficient for 200 RAW images and thus allows long recording series. A new exposure measurement sensor with 180,000 RGB pixels is used for motor detection.


Proven basic equipment


In terms of sensor technology, the Nikon D5 is based on a full-size CMOS (35.9 mm x 23.9 mm) with a resolution of 20.8 megapixels - with the Nikon D4s (test) it was still 16.2 megapixels. In conjunction with the new image processing engine Expeed 5, Nikon promises improved image quality and color gradation. Nikon has also saved on the light sensitivity - this is enough for the D5 from ISO 100 to ISO 102,400 and can be extended to "Hi 5" mode to an extreme ISO 3.280.000


Price and availability


A further innovation compared to the previous model is the support for the recording of videos in the 4K-UHD format. The Nikon D5 records 4K movies with 30p / 25p / 24p and a resolution of 3,840 x 2,160 pixels, in full HD resolution, 50p and 60p are also available as image rates. The MOV format is used with H.264 compression.


The Nikon D5 has a dual XQD memory card slot and a USB 3.0 port to handle the amount of data. Not on board is a WLAN module. An external transmitter must also be purchased for this purpose.


The D5 case has been slightly reworked and now weighs 1,235 grams and measures 158 x 160 x 92 mm. The 3.2-inch LCD monitor for image control now resolves with 2.359.000 pixels - compared to 921,000 pixels with the D4s. The Pentaprismensucher offers a 100% image coverage at 0.72x magnification. For more product details, the Nikon D5 remains faithful to its predecessor.

SSD speed double with raids

How to make your SSD faster: To determine what two SSDs can do in the computer, we have ordered the Samsung SSD 840 and the Samsung SSD 840 Pro in various sizes. In the test with Crystal-DiskMark, the typical behavior of the SSD 840 is shown: the read rates are better than the write rates, both values ​​are clearly superior to a conventional HDD. We then installed a second SSD 840 in the RAID array and repeated all the tests. In fact, they doubled in rates. The reader rates from about 516 MByte / s to fabulous 1115 MByte / s and the write rate from passable 257,4 MByte to a very good 498,5 MByte. As the SSD 840 is also available with 500 GB to buy, we moved to the comparison. As expected, the 500 GB SSD is no faster than the single SSD with 250 GB, but the SSD RAID in terms of speed. The SSD duo is therefore the better choice, especially since there is no big difference between the two variants.

But how does it look, if the double from SSD 840 against the more powerful SSD 840 Pro with 512 GByte can be run? This result also speaks for the SSD duo: In the case of sequential reading, the RAID is twice as fast, while writing is about the same. In view of this result, it is worth taking a look at the costs: Two Samsung SSD 840 250 GB cost together about 290 euros (as of mid-July 2013). A single Samsung SSD 840 Pro with 512 GB is about 400 euros to book. In short, the RAID of two SSD 840s is more than 100 Euro cheaper than a SDD 840 Pro, but you get better performance with RAID.


The small RAID Einmaleins


For a RAID system, several hard disks are connected. The abbreviation RAID stands for "Redundant Array of Independent Disks" which translates as "redundant array of independent disks". The network consists of at least two hard disks or SSDs, with certain advantages for the individual drive. These are specified by the RAID levels. The most important ones are RAID 0, 1 and 5.


Prerequisites for RAID with SSD


In the case of RAID 0, the hard disks involved are combined into a large hard disk. Because the blocks are distributed alternately on the disks, this allows for largely parallel read and write access, which improves data transmission.


Here's how: RAID 0 Setup


RAID 1 is also widely used. If two hard disks are used for this purpose, both are described identically. The contents are mirrored on both plates. The advantage of RAID 1 against a single hard drive is data security. If one of the two disks fails due to a defect, Windows continues to run smoothly and the defective disk can be replaced by a new one. In addition to the hearing costs, the "discarded" storage space is a disadvantage.


A compromise of data security and higher reading speed is attempted with RAID 5. RAID 5, however, requires at least three hard drives, making the acquisition unattractive, especially with respect to SSDs.


Because we want to realize the speed advantage of two SSDs, we set up a RAID 0 on the PC in the following. For this, the chipset of your motherboard must bring the appropriate RAID functionality. Fortunately, this is the case with almost all newer motherboards for AMD and Intel processors. If you are not sure and do not have the manual for the board, install the SiSoft Sandra Lite 2013 software from sisoftware.net. Under Hardware information click on Mainboard and find the exact name of the mainboard. With a search engine you can quickly find relevant pages on the web, which inform you about the RAID configuration of the board.


This is a good opportunity to test the supported SATA standard of the board. Current SSDs have an SA-TA-III interface. If you have a PC with a SATA-II interface, you can use the backward-compatible SSDs, but the maximum data rate is limited. An SSD RAID system makes little sense on a SATA II system.


Theoretically, desktop PCs can be upgraded to SATA III using the appropriate RAID-capable adapters, which we advise against, because the adapters are often limited by your PCI Express connection. A mainboard exchange to a modern board with SATA III and RAID makes more sense here. You can find the supported SATA mode again with Sandra Lite 2013 as described above under Mainboard. Locate the drive controller entry: The information is found in the fastest SATA mode. Only Windows 7 or Windows 8 can be considered as operating systems, since only these SSDs support correctly. A new installation of Windows does not get around, as only the necessary RAID drivers can be integrated into the system. In addition, you need two SSDs, preferably the same model of a manufacturer.


The SSDs are installed similarly to the installation of a conventional hard disk. SSDs have the usual 2.5-inch format for notebooks, while desktop PCs are 3.5-inch standard. In order to install an SSD in a 3.5-inch hard drive bay, an appropriate mounting frame is required, which is ideally included with the SSD, but it can also be purchased for a few euros. When installing, be sure to connect the two SSDs to the SATA 1 and SATA 2 ports on the motherboard. These are usually the fastest ports.


The first time you restart, you must tell the PC that you want to use a RAID system. To do this, call the BIOS, usually press the "DEL" or "F2" button as soon as an image appears on the monitor. For older systems, move the selected selection area to the Integrated Peripherals with the arrow keys and press the Enter key. Look for an entry such as "onboard SATA Controller", "RAID Mode", or "Configure SATA."


Change the existing setting (usually IDE or AHCI) to RAID. Save the settings when exiting the BIOS. Note that the settings on your motherboard can be different and that the Z and Y buttons are interchanged in the BIOS. Newer motherboards with UEFI BIOS are however somewhat comfortable with the mouse to operate. The next time you restart the RAID utility, you will be prompted to configure the RAID. Depending on the mainboard, press the key combination CTRL + I (for an Intel CPU) or CTRL + F for an AMD CPU. You will now see a selection menu for configuring the RAID group.


In the following, we describe the process for an Intel system; the steps are similar for AMD systems. In the main menu of the Intel RAID Utility "OptionROM", select "1. Create RAID Volume" and press the Enter key. In the next window (see screenshot on the left), give the RAID group any name. Use the Tab key to move to the next entry RAID Level. Use the cursor keys to select RAID0 (Stripe). In the next field, press Enter and select the two installed SSDs in the Select Disks window with the spacebar. Press the Enter key. Set the value 128KB as Stripe Size. Use the last point Create Volume to close the operation. An indication appears that all data on the SSDs are lost. Confirm this with the Z key (!). Back in the main menu of the RAID utility, press ESC to exit the main menu and restart the PC.


Reinstall Windows


If the RAID is set, the installation of Windows 7 or Windows 8 is still in progress. Windows provides the necessary standard RAID drivers. After the first Windows start, you should install the latest version of the RAID drivers. For many Intel boards, the TRIM command for the SSD is activated in the RAID. The user is concerned about the release of invalid data areas. If TRIM is not available, the SSD internal garbage collection function has to compensate for this, but it can not work so effectively.


You can get the RAID driver for Intel systems for free on the Intel homepage and the RAID driver for AMD systems can be found at AMD. You can also monitor and / or change the RAID on Windows.

The best 50 compact cameras

In the search for the right camera model you can already despair – there are simply too many. But how can we solve this problem? About a megatest like this – and the right user profile. For this purpose, we divided the test field into several categories. Are you an ambitious hobby photographer who attaches great importance to uncompromising image quality? Or do you need a compact compact? Our comments on the camera types should help you find the right category here.

If the camera type is fixed, go through our table until you find a model that suits you.


Picture noise at dusk


Such a special requirement could be, for example, if you photographed frequently in low ambient light, for example in the evening hours. Then you should take care that the camera has a low noise even at higher sensitivities. The noise is directly related to the distance of the photocells on the sensor. The more dense the pixels, the more electrical interference that causes the noise.


Therefore, find out a camera where the pixel pitch is large. These are tendenziell incidentally, cameras that have less megapixels. If you frequently shoot holiday pictures in the blazing sun, you should take care that the camera offers a short shutter speed to control the enormous amount of light. Essential are short shutter speeds for mega-zoom cameras as well.


Because a photographer's rule is: Use at least the reciprocal of the KB focal length to get a blur-free image. We define a mega zoom camera from a zoom factor of 20x. However, this value only indicates the "wide-angle multiplier". By the way, if you simply want to take pictures of your favorite photographers and have no special wishes, you can even save money - with entry-level compacts that do not have to hide in terms of picture quality!

SEO experts will find

What do you do if you are looking for a specialist for a topic, but do you know neither yourself nor your acquaintances? For example, a tax consultant who is familiar with the construction sector? Or a lawyer who is fit for media law? Or a business consultant with experience in optimizing business processes?


Professionals for specialists


Most people are using the PC in such situations today, and are using Google & Co. to find the right keywords to find potential support. This is why it is important for companies today that their website is quickly and frequently found in search queries - for example, because it is displayed far in front in the hit lists.


This is not the case with many websites. The reason: They are often optical


"Gorgeous", but unfortunately they were not optimized by the agencies, which they created, on the web search. So you do not get to it at all in search queries or very late.


Registering companies, they often consider employing a search engine optimization specialist (SEO), a specialist who optimizes their website. For example, to increase the access numbers to their website. Or their website in the hit lists is not far behind the competitor sites. In the following, we will give you some tips on how to search for such an SEO specialist.


Tip 1


Ask first-time acquaintances and business partners if you can recommend an SEO support. If not, check out some websites that are well on the net, in their source code or imprint, if the SEO support is called there. For example, you may be looking for small providers that you can take care of (and which a small business can pay).


Tip 2


If this does not help, search for search engine combinations such as "search engine optimization consulting" or "consultant optimization website search engines" at Google & Co. First of all, create a list of potential supporters. Make a big question mark behind all potential candidates who are only on the first hit pages due to Adwords ads. Because a SEO specialist should be able to bring his page forward without such ads.


Tip 3


Check out the websites of the potential supporters. Are they really SEO specialists or advertising agencies that claim to be fit for "search engine optimization"? The practice shows that in many "creatives" this is not actually the case.


Tip 4


Call on the potential supporters. Ask them which keywords they have optimized their own website. Then check out these terms by entering Google & Co., how well the candidates are based on their own keywords. If your conclusion is bad or only mediocre, you should exclude the support. Because an SEO expert should at least be able to bring their own website to the front of their keywords.


Tip 5


Ask the remaining candidates to tell you two or three sample customers whose web pages they have optimized search engine optimization - along with the keywords they've optimized these pages for. Then check out how well these customers are actually related to the keywords.


Tip 6


Name the remaining candidate the most important keywords to which you want to optimize your site. In this case, you should also name the candidate two or three general terms such as "coaching" or "business consulting" or terms like "project management", where you have very strong competitors such as universities or large companies around the front lists

Then ask the candidates for an estimate of how far they can get your website up and running in Google & Co. hit lists. Be cautious with all providers who promise you the most general or highly competitive terms "We bring you or your company to page 1 or 2". This is often unrealistic.


Tip 7


If you can not land well in front of a highly competitive search term such as "project management" or a generic term such as "coaching," ask the potential supporter for a suggestion as to how it still achieves your most important target customers .


A solution might be to optimize your website instead of the term "project management" solely on keyword combinations such as "Project Management Autoindustry". Or instead of the term "coaching", use the terms "sales coaching" and "sales coaching" - as long as this fits your positioning.


Tip 8


Ask the vendor whether, and if so how, he can help you build links to your website so that your website is ranked better in Google & Co. ranking. Exclude all providers who suggest to buy such links. Because this is punished by the search engine operators, if you register, with a kind of "space reference". This means that your website will either no longer be displayed in search queries, or will only be displayed far back.


Tip 9


If you have chosen a provider, do not close a long-term "care contract" with him. Instead, for example, you may want to sign a three-month agreement by doing defined actions such as optimizing the source code of your website or increasing the keyword density on your website. Then, after three months, check what the activities have brought you before giving the support a follow-up to the support.

Samsung and Philips

Good approach


Web TV


Samsung's upscale class of televisions offers both Internet features, as well as a Mediaplayer menu item called Content Library. There are pictures from the fields of art, nature and animals, recipes, games (currently bowling and a puzzle game), a children's section with English songs and texts as well as a wellness area with chillout music, fitness exercises and massage tips .


Picture gallery


In terms of Internet, Samsung's TV also offers little: you have access to YouTube videos, but only in the SD variants, Yahoo News, Yahoo Weather as well as Yahoo Finance can retrieve flickr pictures and Sudoku play - more widgets are to follow. These widgets open at the bottom left devon at the bottom up and lie half-transparent over the current TV picture.


If desired, you can also reduce the TV image so that it is to the right of the hinged widget. However, the YouTube interface will pop up as you fill a dot from the widget menu as well as the Sudoku game. While the space for widgets is sufficient for weather reports and the latest stock values, Yahoo News scores just one or two sets.


What really bothers us is the slow response to the pushback of our model Samsung UE40B8090. Apart from a short flashing of the television lighting, there is no indication in the widget main menu whether the integrated software has registered the remote control command. Even a progress bar is in vain. In addition, navigating the menu from one point to the next takes more than half a second.


In the YouTube area, the next weakness is revealed: The software does not handle SMS-like fast input via the number buttons, but you have to navigate letters for letters through a displayed keyboard field - here at least with a 1/4 second response time. If you enter another letter, the software looks for matching videos and displays their thumbnail with a brief description in the right-hand screen area.


This makes the processor sweat, because during the search, the cursor control becomes much slower. If you enter more than one keyword, it does not seem to search for the individual terms, but for the complete phrase. You can not sign in to your own YouTube account. Despite all this criticism in Internet mode, it is enough for an occasional look at the news and the most popular YouTube videos. The device can rather score as a mediaplayer - more about this in a separate box.


If the term Internet TV fits on a television, then most likely to the Philips models, in our case the Philips 52PFL9704H / 12. On the homepage of the Internet function, which is preceded by an optional registration, you get 20 links, including YouTube, eBay, tagesschau, Bild.de, Kino.de, Kicker, wetter.com, WeltOnline.

Selecting "Show all services" will get even more links sorted by category. If that is not enough, you can also specify your own URLs. However, there are huge differences: the services presented by Philips are optimized for viewing on TVs from a distance of several meters.


Own URLs, on the other hand, usually appear in the normal look known by the PC - no wonder the Opera browser works in the background. However, there are also restrictions: First of all, the TV does not support flash - which could also be difficult with regard to navigation, because the cursor is not freely controllable but jumps on a website from link to link. A second point, which can still be detrimental at the moment, is the transferred user agent data: The television logs in with the identification


On a web server. First of all, the web server must be able to handle the CE HTML tag. Secondly, it must ignore the profile name in pointed brackets, which is also necessary to identify the device on the Philips server, or at least ensure that the request is not rejected. Furthermore, it can happen that, as was the case with Spiegel.de, it is forwarded to the stripped down page for mobile devices.


At Philips, the TV picture is completely replaced by the Internet menu - times just in addition to the television additional information retrieve, so does not work currently. At YouTube (also currently in SD only) and other services, you can not only register, but also enter search terms by SMS input field. You can even place orders with PosterXXL.


Overall, however, the sluggish navigation with a 0.5 second response time is also a source of frustration - after one or two hours of trial and error, certain fatigue phenomena occur which lead to a more regular use of a selection of services. And also browsing through YouTube or eBay is more of a matter, if you take a lot of time or the PC is just not tangible.
