Because of that, you subscribe to the c't. I would like to put the following up for discussion on the subject of anonymity: If only one Android cell phone is registered with Google via WLAN in a household, the IP address of the searcher can be compared with the registered Google account data with every Google search within this network from any computer it is from the same IP address. There is no anonymity there, right? At least to Google and thus maybe also to the floppy hats collected. If this conclusion is correct. So maybe it should be in an article, because this is a common case. Michael Kolb Your conclusion is not mandatory if a proxy service often exchanges the IP address between the WLAN and the remote station (as in the case of Tor or some VPNA anonymization services). Telltale JavaScriptI am relative been an enthusiastic user of JonDonym and would like to continue to use it if it weren't for the problem that visiting many, perhaps most, websites is still possible without JavaScript enabled, since their content can only be partially or fully displayed in a browser with JavaScript disabled not build at all. An active JavaScript, however, reveals the real IP address to anyone who wants to know it, and nothing can be changed via Tor or JonDonym. Every now and then I look in the JonDonym forums and can then read that this fact has not become clear to many of the users. Therefore, my specific question for you: Is there perhaps a way in the meantime, even with activated JavaScript, the IP address of my system Georg HeinrichsanYou have to make sure that no data traffic can bypass anonymization. Active content and Flash applications can bypass proxy solutions such as those used by JonDonym and Tor. This is not possible, for example, with virtual network cards for VPN anonymizers. You are on the safe side if you route the data traffic via an external anonymization router. However, this requires technical know-how and requires that the anonymization of the selected service works in principle.1 0-watt PC is the better NAS multi-talent NAS, cheap network storage for a small network, c't 20/1 3, 5. 116When I look at the price for the NAS and the power consumption, I look back through a booklet and build the 1 0-watt PC from the building proposal. This will need more power with the disks, but is then about the same as the NAS. At the same time, however, I get a full-fledged PC (which justifies the extra charge) that is still running, a huge gain in convenience. When it comes to prices and power consumption, the point of a NAS doesn't make sense to me, especially since I really get the speed over the network with the PC that the hard disk is capable of. In addition, if you really need a lot more hard disks, you can use USB 3.0 etc. Bring a whole armada of records into the network. RAID and Co. also offers Windows. You can also operate your own cloud, etc. there, regardless of manufacturer. Conclusion: A PC is the better NAS. Martin Wäldler10c't 201 3, issue 21

Readers' forum I letters, e-mail, hotline office app not taken into account, documents while traveling, office apps for Android smartphones and tablets, c't 20/1 3, p. 144 I was delighted to read the article about office packages for Android.My question would be, why was Polaris Office not included in this test? I use this package on both my smartphone and tablet and I am actually very satisfied with the current version. Martin Stockinger We did not include the app in the test because it only runs on a few smartphones, especially from Samsung, and is then preinstalled on them. Set the 3D printer correctly, c't 20/1 3, p. 164 I would have another suggestion for the adjustment screw of the 3D printer: Instead of the lock nut at the bottom, insert an M3 spacer with an internal thread on both sides. These bolts are available in lengths of 5 to 30 mm in 5 mm increments. Then you would have an operation with a screwdriver and open-end wrench L The fact that the lock nuts loosen when you turn the screw is in the nature of things, and turning the screw with the lock nuts tightened is also not technically correct. The correct order is - especially with such a difficult adjustment - fixing (and hold it in place) the adjusting screw using a screwdriver or open-end wrench, loosen the lock nuts, turn the screw, tighten a lock nut, check the setting. If the ideal setting has not yet been found, repeat the steps. After a successful setting, the second lock nut can then be tightened. Overall, the structure of the limit switch is questionable. On the one hand, the combination of a thin screw and a long actuator right "spills", on the other hand, both start-ups are likely to cause a lot of potential for destruction if the normally open contact is used. If the cable is defective or incorrectly connected, the extruder then rushes past the switch and is only stopped by the heating bed - which causes defective components because the fault is not immediately recognized due to the short travel distances. Or in later operation a broken cable creates the potential for destruction ... In mechanical engineering, such a constellation is avoided by arranging the switch on the side of the travel path. A small angle at the point of the switch and a short M3 screw with lock nut attached directly to the aluminum plate of the extruder arm are certainly far more effective, easier to adjust and maybe even a few cents cheaper. Carsten Bohemann Be careful with acetone polishing mist, harden 3D prints and bring them to a high gloss, c ' t 20/1 3, p. 162 The problem with acetone is not the boiling point of 56 oc mentioned in the article, but the flash point below -20 oc. This means that even at a very low room temperature there is enough solvent-air mixture above the liquid level that can be ignited with an ignition source. Ignition sources abound in your article. The lower explosion limit of acetone is only 2.5 percent by volume. Flash flames, burning acetone running around and in the worst case ("I close the lid properly so that it works well") an explosion are inevitable for the inexperienced hobbyist. I work in a large mechanical engineering company. In ours Wherever possible, we have diverted acetone from the company as an auxiliary and operating material. The handling was simply too dangerous for the employees - logically in most cases not chemists. Open the window and stop smoking is not enough. There is another reason to forego a polar solvent such as acetone: After processing, ABS has tensions in its internal structure, both in 3D printing and during injection molding. When exposed to a polar solvent, this first leads to hardening and then to stress cracks that destroy the workpiece. Direct contact with the liquid is not even necessary (would dissolve ABS anyway), but the vapors are sufficient. You can fi nd important information about acetone in the database of the employers' liability insurance association (see c't link). The editorial team also confirms at this point that handling acetone requires great care, sometimes it also harbors health hazards. Risks exaggerated, light traps, practical experience with A mini solar system, c't 19/1 3, p. 86 I am disappointed by the extremely negative basic tenor that is generated by omitting any positive arguments. In addition, there is a subtle distortion of the risks. I have been running a mini-system with two panels myself since June and have dealt extensively with the topic, although unfortunately there were also many breakdowns and teething problems. Nevertheless, I do not come to such a negative conclusion as you. Positive aspects that were not mentioned: -Each locally generated and directly consumed kWh saves at least 1.5 kWh of primary energy (rather more) because there are no transmission losses - no grid expansion required - no subsidy required - a study by UBS comes to the conclusion that solar energy is now The 2.0 age begins, with many unsubsidized small systems for personal consumption - the energy consciousness increases enormously (personal experience in the family). In a letter to the editor this was called a "fun factor", I would rather call it the more conscious use of energy and the joy of saving. To put it clearly: I am against installation via socket and have my system correctly connected to the house distributor. Nevertheless, an unbiased journalist should mention that connection via a socket is permitted in the Netherlands. When connecting a system with, for example, 250 watts, the increased risk is negligible provided an inverter with NAS protection is used (which should be a matter of course). FSyncMS synchronizes Firefox bookmarks and settings, c't 19/1 3, 5. 144 As described in the article, I installed the FSyncMS server - all settings were also set correctly. The connection worked without any problems - however, Firefox then constantly asks for a username and password. Even a renewed input help does nothing, because according to the browser the login data is "not valid". But the error is not in the browser: Some Apache servers apparently need an adjustment of their settings in the.htaccess file and a change in the PHP file weave_utils.php. Details of the solution are described in a bug tracker entry for the FSyncMS project (see ct link). C. BalkeSupplementations & correctionsPrice reducedHotline, LTE router interferes with home theater controlFS 20, c't 19/1 3, p. 138 The price of the ELV superhet receiver, which can make many FS20 modules L TE-proof, has been reduced.

First the pleasure, then the work Highlights from the demo party Evoke 201 3, c't 20/1 3, p. 76 The JavaScript demo from TRBL is called "Apophenia", not "Apophrenia". Apophenia is when individual elements condense into a random pattern or context for the viewer - for example into a cloud that looks like a sheep. Www.ct.de/732101012c't 201 3, issue 21

Florian Müssig, Andreas StillerFrom Quarks & Co.News from the Intel Developer Forum2013 in San FranciscoWhile Larry Ellision's Oracle crew fights desperately against the challengers from New Zealand in the America's Cup in front of Alcatraz, a few hundred meters further a few thousand developers are listening to the words of the new Intel boss Brian Krzanich. And he has a lot to tell. The numerous new announcements at the IDF in-house meter show how wide the spectrum of processors is now: For even more powerful (Cioud) servers, there are new Xeons with an ivy bridge interior (see also p. 1 24), In the tablet market, the next Atom generation Bay Trail is set to compete with the ubiquitous ARM chips, and Intel plans to play with its new Quark processor series for small devices such as smartwatches and the like. For the first time, Brian Krzanichas head of Intel's developer forum in San Francisco. He wants to focus the world's leading chip manufacturer much more on mobile devices, i.e. on growth markets. Tablets will soon start with the new Bay-TraiiAtom, both with Android and Windows 8.1 (see also page 53). The basic core architecture of the new Atom CPUs with the code name Silvermont was unveiled several months ago [1]. The Atom C2000 server offshoot (Avoton or Ra ngeley) was launched at the end of August in order not to overload the IDF with new products. The new Atoms for tablets are called Atom Z3000. Sometime later, the Silvermont offshoot Merrifield for smartphones and a variant without a code name for automotive use will follow. Compared to the previous tablet chip Clovertrail, which is marketed as the Atom Z2760, Bay Trail offers a number of performance improvements. Instead of two cores plus hyper-thread now four fully-fledged cores are available, which also work out-of-order like the large core processors - Hyper-Threading is no longer necessary. Every two cores share a 1 Mbyte L2 cache. The memory bandwidth has increased dramatically thanks to the switch from DDR2 to DDR3 chips; Depending on the model, LPDDR3 or DDR3 L-RS chips are controlled (see table below). Intel has also completely overhauled the integrated graphics and has abandoned the PowerVR GPUs previously used under license. Instead, there is a HO unit borrowed from the third Core i generation, lvy Bridge, including a QuickSync transcoder. The number of GPU units has been reduced to four EUs (lvy Bridge: six [HD 2000] or sixteen EUs [HD 3000]) Capabilities including DirectX 11 support but nothing changes. The change in GPU architecture gives hope that Intel will deliver faster and more frequent driver updates in the future. The chip giant has not exactly covered itself with fame with the PowerVR offshoots. Intel is unusually covered with some important key data. Despite the increased performance, Bay Trail should not consume more electricity than its predecessor Clovertrail, but exact figures - be it the vaguely worded SDP (Scenario Design Power) or the more specific TDP (Thermal DesignPower) - were not mentioned. The information on the clock frequency is similarly vague: mean here Burst Up to 2.4 GHz are achieved, but unlike the large core processors, Intel does not specify a guaranteed base clock. All unneeded units would be switched off by the power management and the cores almost always worked at the burst limit, so specifying a basic clock rate would not make sense, according to lntels reasoning. First Bay Traii Benchmarks Shortly before the IDF at the headquarters in Santa Clara, California, we were able to take the first measurements on a Bay Make a Traii reference tablet. This was equipped with the finest components, namely the flagship Atom Z3770 and a 2S60 screen. There was a choice of models with Windows 8.1 or Android 4.2.2; We mainly used the former. In the performance benchmarks, the Atom Z3770 makes the direct competitor from AMD look old: The A6-1450 (Temash) is beaten by a factor of 2 in CPU-intensive tests, the similarly fast M-5000 (Kabini) burns far more energy. Bay Trail poaches here in regions that were previously served by CPUs such as the Core i3-3229Y.

The comparison between Bay Trail and the ARM competition is exciting. Obviously, the Z3770 cuts a fine figure with the Coremark (see table above). But be careful: The values ​​are only comparable to a limited extent due to the different clock frequencies and core numbers as well as the not known TOPs. The test sample of the Z3770 only delivered 26S5 points per core and gigahertz. So it not only has to beat ARMsCortex-A 1 5 (achieved 3262 Coremark points in Exynos 5250), but also Qualcomm's Krait 400 in Snapdragon800 (31 02 points). UMTS or L TE must be retrofitted with additional chips on Bay Trail. According to the current state of affairs, even the smartphone offshoot doesn't get an integrated LTE modem: In a prototype smartphone with Merrifield atom shown by Krzanich, the in-house L TE add-on chip XMM7160 took care of the cellular connection. That should disappoint analysts, because Qualcommden dominates thanks to built-in L TE radio technology Smartphone market. As a consolation, Krzanich promised an improved L TE chipXMM 7260 for 2014, which should be able to handle LTE Advanced. Pentium and Celeron with Atom internals In view of the high performance that Bay Trail shows, it is not surprising that Intel also offers affordable notebooks with the processor and drive desktop PCs. The name Atom is not found there; instead, the newcomers run under the brand names Celeron and Pentium (see table below). This not only brings advantages for Intel - such as higher margins because the tablet processors are cheaper to manufacture than later trimmed Core i - but -Or also for buyers who know what to expect. The computing power is actually quite low, but so is the power consumption and the price. And unlike the previous Celerons and Pentiums, the HD video accelerators of the GPU are also active in the Silvermont SoCs - the QuickSync encoder, however, is disconnected. In contrast to the tablet variants, typical PC interfaces such as SATA or PCI Express are available; the memory controller controls normal DDR3 modules. USB 3.0 is on board despite the low price orientation. The computing power of the Silvermont Celerons is not that bad if you take the 1.5 Cinebench R11.5 points of the AtomZ3770 with four cores as a basis: The two Sandy Bridge cores of the 17 watt cheap Celeron 847 deliver just 0.83 points at 1.1 GHz; In the single-thread run they are also not significantly faster with 0.43 to 0.4 points. Intel expects that cheap notebooks - basically netbook successors - with Celeron N2805 and 11, 6-inch displays can be available from 199 US dollars. However, it is questionable whether this can be achieved with Windows 8. At the IDF, new ChromeOS notebooks from Acer, HP and Toshiba were presented in cooperation with Google, but they were again equipped with Hasweii chips. For cheap tablet / notebook hybrids with touchscreens and detachable keyboards, Intel expects prices starting at 399 US dollars including Windows 8, if the manufacturer offers the Microsoft discount as part of the special program "Smaii-Screen Touch" Bay Trail for notebooks and desktop PCs.

current I Intel Developer Forum Shrunk: Up until now, a 30-inch webcam was still quite bulky (right), but with the Broadweii generation of ultrabooks, it should disappear into the lid like normal webcams. (SST) - for which the BayTraii Celerons and Pentiums are basically approved Broadwell follows Haswell Although CEO Brian Krzanich had already shown a reference notebook with a Broadwell processor in his opening keynote, he did not want to use it yet. The following day, Kirk Skaugen, the boss of Intel's PC Client Group, compensated for this with a side-by-side demo: Haswell decreed against Broadwell campaigns. It was not about (PUPerformance, but about energy consumption.Skaugen had used two reference systems for the comparison: One was equipped with a Haswell manufactured in 22 nm technology, the other with a Broadwell manufactured in an even finer 14 nm process. The processors were set in such a way that they provided the same computing power in CineBench, but Broadwell did the computing with them About 30 percent lower energy consumption: 4.9 instead of 6.8 watts. Broadwell also happened again and again in the technical sessions and discussions with developers. It now seems clear that Broadwell is primarily intended for mobile systems and is therefore only available in bulk in solderable BGA housings. According to reports, Intel is not planning socket versions for normal desktop mainboards - apart from maybe one or two special chips. There should be two SoC variants for ultrabooks, tablets, etc.: one that is pin-compatible with Haswell, which the manufacturer simply offers as an additional option can be soldered into the existing device design, and a new one with a significantly smaller footprint. Pin compatibility is possible not least because the chipset of Hasweii SoCs is also on the carrier board - and also because not so much has changed on the peripherals. Intel wants to establish new interaction methods for Ultrabooks with Broadwell. The company's engineers have now reduced a 3D camera, which previously had to be clipped on as a bulky peripheral, so that it fits in the frame above the screen like a conventional webcam. The future ultrabooks should also be able to be woken up from standby by voice. In order for the latter to be as energy-efficient as possible, the SoC has its own audio DSP - so the CPU does not have to constantly listen and can remain in a deep sleep. 14 nm and USB 3.1, according to Krzanich, Intel will do the to deliver the first Broadweii chips later this year - which is more likely to apply to evaluation samples for hardware manufacturers and less to final products to end customers. Some IDF visitors were surprised that there was no information about the 14 nm production itself. In the past, Intel has always been frank about new process technologies when such products were around the corner. This suggests that something is still going on with Broadwell and probably also with the Atom processors of the Airmont generation, which have also been shrunk to 14nm for 2014. USB 3.1 will probably come even later than 14 nm chips. In view of the small version jump, one could assume that there are minor improvements and optimizations behind it. In fact, USB3.1 brings a lot of new things, starting with the data rate: Instead of 5 Gbit / s gross (at 2.5 GHz signal frequency) there is now a whopping 10 Gbit / s (5 GHz ). Actually, the USB-IF (USB lmple-conspicuous: lntelsMobil boss Hermann Eul with a Bay-Traii-Wafer18menters Forum) wanted the change from 8b / 1 to the much more efficient 128b / 1 30b coding for USB3.1 in PCie 2.0 to PCie 3.0 copy, but simulations would have shown that even single unfortunate bit errors could have blown the USB connection. For this reason, an additional 2-bit header or 128b / 1 32b coding was chosen. Instead of a full 20 percent overhead with USB 3.0, only around 3 percent are lost with USB 3.1. More than twice the USB 3.0 bandwidth is available. Another important goal of the development was mechanical compatibility with existing USB 3.0 plugs and sockets. However, your key electrical data have been changed with regard to shielding and grounding in order to accommodate the higher signal rate. It is possible that the maximum cable lengths will also shrink. According to its own information, the USB-IF has never specified specific maximum lengths, but with USB 3.0 the framework conditions have been set in such a way that manufacturers can produce cables up to three meters in length at a (unspecified) "reasonable price". The same price was used for USB 3.1, but expected because of the slightly higher effort in terms of signal integrity now only about one meter in length. It will be interesting to see what that means in reality: In the c't laboratory, cable problems are already the most common cause of problems with USB 3.0. When asked, the engineers confirmed previous problems, but this is precisely why the specification has been specified elsewhere. USB3.0 allows up to 20 dB signal attenuation between two controller chips - but nowhere was it regulated exactly where they were allowed to drop. So three components from different manufacturers (Hast, Cable and Client) each with 10 dB attenuation can be within the specification, but you will never be able to operate the three together. These details do not seem to be known to all manufacturers - or under the price c't201 3, Issue 21

current I Intel Developer Forum pressure to be forgotten - because some USB 3.0 devices just work badly with the supplied red cables. The manufacturer could then coordinate at least two of three players with one another. USB 3.1 allows the same 20 dB signal attenuation for the entire route, but the distribution is now precisely defined: 6 dB are available to the cable and connectors at both ends, while the host and client receive 7 dB each. It may be surprising that the smallest part is allowed for the cable. However, engineers have to bear in mind that devices such as smartphones, tablets or ultrabock coffins are tight and that the USB lines therefore sometimes have to cover long distances on the circuit boards - because other connections are even more critical and block the direct path. If long paths are stronger than 7 dB, they still have to open Active repeaters can be connected to the board, the exact specifications of which will be nailed down by the end of the year. With the repeaters, active cables are possible that go far beyond the length of passive ones. The developers of hub chips have to take care of most of the work. With USB 3.0 this was not so difficult, because it introduced new cables, no conversion of signals was necessary because USB 2.0 and -1 .1 connections had their own data path. A USB 3.0 hub consists of a conventional 2.0 hub and a separate one for Superspeed. With USB 3.1, the latter becomes much more complex. Must now digest different link speeds (5 GBit / s or 10 GBit / s) both in the upstream and in the downstream, accordingly have a buffer ready for each port and translate when required. In addition, several transmissions have recently been allowed to run simultaneously and packets may be re-sorted in order to utilize the upstream. The development of USB 3.1 -capable chips has already started at all the companies affiliated with the USB-IF, but there should be no silicon before mid-2014. The final compliance specification with all the tests that have to be passed for the new SuperSpeed ​​+ logo is also not expected to be available before the end of 2014. As in the past, there are separate controller chips for the time being, and the engineers employed at Intel did not want to comment on the integration in chipsets. In our estimation, even for the next but one Ce-i generation Skylake, the first in 2015 should be too tight, so that we expect its successor with a USB 3.1-capable chipset at the earliest. Clusters, Atoms and Quarks The official launch of the new Xeon family ES-2600 v2 with to with twelve cores, manufactured in the 22-nm process, Krzanich left his server manager DianeBryant. c't was able to test the top product ES-2697 in advance (see page 124), there you can also fi nd all details about the new Xeon processors. As a launch partner, you would actually have expected Apple with the impressive cylindrical MacPro design miracle. After all, it uses one of the new Xeon ES processors with up to twelve cores. But the Cupertinos were probably too busy with their iPhones (see page 62) - or the Apple developers are still in the process of optimizing the OpenGL drivers for the two AMD GPUs. Up until now, AMD's OpenGL support was, to say the least, suboptimal. When asked, Bryantgrob gave the dates for this r the two planned four-socket versions with lvy Bridge known, which they say will come out in the first quarter of next year. As with SandyBridge, a low-cost version is planned for the LGA201 1 socket with only two QPI links (lvyBridge-EP 4S). In addition, there is the Xeon E7 noble version with four QPI links per processor, which was omitted from Sandy Bridge. The latter will not be socket-compatible with the older Westmere EX (Xeon E7-4800), but will be equipped with the R1 socket, with QPI 1.1, with C602 chipset and with DDR4 support. The so-called Brickland platform should then provide the basis for at least two further generations: Haswell EX and Broadwell EX. There is also reliable evidence that the self-booting Xeon Phi (Knights Landing) is designed for this platform. But otherwise nothing was heard from the IDF, Intel will reserve this for the supercomputer conference SC1 3 in Denver in mid-November. A Bay Traii atom (above) and the Quark Xl 000 server manager Diane Bryant presents the new Xeon line E5-2600v2, but neither the lvy Bridge EP Xeon family ES-2600 v2 nor the new Atoms for tablets nor the pink sweater of the mobile manager HermannEul, but an unexpected newcomer, the Quark processor. Okay, another newcomer caused even more sensation on the second day of IDF: The hybrid i8 presented by BMW's IT boss Mario Müller on the IDF stage received his downright frenzied applause, but less because it uses an atom processor in the navigation system ... Whether BMW later also wants to use quarks, one does not yet know. This miniprocessor intended for embedded use is said to be only one fifth the size of an atom and one tenth of its energy consumption. Intel boss Brian Krzanich only spoke of "wearable devices", as portable devices such as smartwatches, but de facto intel wants to penetrate deep into the domain of ARM with him, according to the motto: As you me, so I you. The new buzzword for this area is "Internet of Things ". To do this, Intel is once again taking a tried and tested old design out of the drawer, the 32-bit Pentium 54C, providing it with the most modern power management and a few extensions, and manufacturing it in current manufacturing processes in the factory service. The QuarkX1 000 shown is apparently still manufactured in the 32 nm SoC process. It is to be expected, however, that it will soon be offered in parallel to the Atoms in 22 and 14 nm. Intel praises its "standard industry software support". After all, they have already prepared the Linux kernel with Larabee and now the Xeon Phi so that old Pentium kernels with Pentium unusual extensions. However, in order to really arrive in the embedded world, you actually have to have an IP license he-20c't 201 3, issue 21


current I Intel Developer Forum Asus Overclocking Party: This is how the Hasweii processors make a lot of steam. So the manufacturers can incorporate the cores into their own designs - as esARM and others practice with great success. So far, however, Intel only wanted to sell finished chips from its own fabs and not give IPs out of the house. If Intel had been a bit more flexible in the past - the ARM competition would never have arisen. The Acern developers Wilson and Furber had once applied for a license for the 80286 and then quickly created their own processor out of frustration at the rejection, the ARM 1. Due to its closeness, it may also have been an essential reason for the fact that smartphones have so far not been well received in the smartphone scene. But with Quark everything is supposed to be different. Intel describes it as "Open Architecture". Quite so open - Krzanich admitted in the subsequent questionnaire - intel does not want to handle that. The design itself does not want to be published as source text, but only to reveal the internal interfaces, the header files for the hardware, so to speak. Descriptive language. Third-party companies can use this to connect their own modules, for which Intel, as a forge, manufactures the chips. The concept of the heterogeneous system architecture from AMD is a bit similar. Speaking of AMD. The company used the opportunity IDF, like every year, for its own press conference in a neighboring hotel, but rather than showing a new embedded roadmap (see page 34). DR4-FrankensteinFor DDR4 you don't have to wait for Haswell or Broadwell, the lvy Bridge-EX is already designed for rDDR3 and DDR4. The memory manufacturers use a test platform equipped with it for early experiments and also for demonstrating your DIMMs on d em IDF. Under the hood it must be pretty wildly thrown together, as its nickname "Frankenstein" suggests. The "Memory Community" exhibit together - A colorful selection of Chromebooks with Hasweii Celerons, here HP's Pavilion 14 from manufacturers such as Samsung, Micron, SK Hynix , IDT and lnphi were therefore not allowed to look under the hood. The housings of their test systems only had small peepholes on the memory tier. In addition, a first Hasweii-E system with up to 14 active cores and DDR4 support could be seen. Instead of performing a memory benchmark Ia stream, which the memory companies were apparently not allowed or wanted to do, ran in unison everywhere the Linpack benchmark, which, if programmed correctly, generates almost no memory load. In addition, the Linpack values ​​for the single-processor systems with 12 or 14 cores were only 1,06 to 108 GFiops. The systems run on a fairly low flame and without turbo. For comparison: Two of the new Xeon processors (E5-2967 v2) came to 467 GFiops in the imc't laboratory. Either DDR4 is not yet fully developed or Intel does not want to let out any possible performance values. The DDR3 competition, however, put up a lot with Cersair with up to DDR3-2800. Well-selected Cersair modules even reached 3900 MHz at the Asus' overclocking party, but cooled with fl liquid air. Three simmering and steamy systems with X97 board and Intel Corei7 4960X, powered by up to four 1.2 kilowatt power supplies competed there and achieved numerous records of up to 5.8 GHz, such as 3DMark1 1 (Entry) with 38231 or Cinebench 11.5 (6-core) ) with 17.65 points. Intel also played a strong role in overclocking and held a session together with Asus' specialist, JJ Guerrero:., Overclocking Unlocked Intel Core Processors for High Performance Gaming and Content Creation. "The Core i7 4960X can keep up with this even without liquid air 4.75 GHz. Even before Iris Pro notebooks, Intel and Asus didn’t stop, and the last highlight was overclocked SSDs, which rattled with 625 instead of 400 MHz. Chromebocks were not part of the overclocking games, although Asus is now also among the providers of this device category belongs. In addition, Acer, Hewlett-Packard and Toshiba announced an update of their series on Hasweii processors at the IDF. These are mostly the cheap versions that are not so suitable for overclocking and are marketed as Celeron and Pentium. After all, the trestles should bring up to nine hours of running time. In a round table from Google, Intel, Hewlett-Packard and Acer, it was learned that future Chrome OS apps should run offline much more frequently than before. Acer currently offers far more than the current 16 GByte local flash memory, for example an additional 320 GByte hard drive. Add to that the 100GByte free for one year on Google Drive. HP's 14-inch Pavilion 14 Chromebocks are to be sold in different colors at an attractive price of $ 299 in the American Christmas shop. The predecessor, equipped with a Celeron 847, costs 299 euros. Later, an LTE version will also be available for a few dollars more. Acer emphasized that they wanted to bring out the new C7 with 11.6-inch display in all countries supported by Google for Chrome at the same time, including Germany. Acer has not yet given the price, it should probably be in the area of ​​the current C7 Chromebook in the USA Range of 199 dollars. In Germany, the forerunner is offered as the C71 0 with a 320 GB hard drive for just under 280 euros.

current I SmartwatchesNico JurranSmartwatch-WelleAlways more information centers for the wristSamsung ushered in a new series of smartwatches with the Galaxy Gear at the beginning of the IFA, followed by a veritable flood of models. What is actually a SmartThe Swiss UnWwatch company Kronoz sees its models MyKronoz ZeclWatch and for ZeBra around 70 euros each as a kind of Bluetooth hands-free system for incoming calls on the smartphone. The new ZeNano, which is still reasonably priced at just under 130 euros, can also be used to initiate calls and send SMS, but nothing changes in the basic concept. As a result, Kronoz has a standby time of 120 hours and talk time of up to 4 hours. Pearl, on the other hand, has real "cell phone watches" in its range, on which a fully-fledged mobile operating system runs and which can be used as a smartphone replacement thanks to its own SIM card. The latest Simvalley AW-41 4.Go model, which is now available for 200 euros, offers a 4 cm multi-touch display (240 x 240 pixel resolution), a 1.2 GHz Cortex A7 CPU with two cores and an Android 4.2 operating system. 2.The memory can be expanded to up to 32 GB with microSD / SDHC cards. GPS, acceleration sensor, electronic compass and 3 megapixel camera round off the AW-41 4.Go. Since individual characters are only poorly displayed on the small screen, Pearl supplies a touchscreen pen. Nissan even wants to connect the driver and car with its Nismos: the smartwatch is linked to the on-board electronics via Bluetooth Smart and measures the driver's pulse via built-in sensors, among other things To recommend that they take their foot off the gas in stressful situations. The watch is still only available as a concept, but Nissan has already announced that it will run for a week on one battery charge. Beautiful Sony said goodbye to the OLED display of the previous model with its SmartWatch 2 (see c't 12/1 3). The model, known for short as SW 2, instead uses a transreflective display that shows the time continuously for days, as it consumes little power and works in this (monochrome) mode without backlighting. Press the button on the side to wake up the SW 2, which also activates the backlighting. The colored menus continue to be navigated using (multi) touch gestures, which worked quickly when trying it out at the IFA. There are also three buttons for global commands. The watch should actually be available from September for around 200 euros. So far, however, there has only been a pre-series model with limited functionality to be seen behind closed doors, which displayed incoming phone calls on the Android smartphone connected via Bluetooth. The Taiwanese company Sonostar caused a sensation with the announcement of a smartwatch with a curved e-paper display. This is where the very energy-saving e-link technology, which one knows from e-book readers, should really come into use but a memory LCD from Sharp. Sonostar is hoping for sales to start in December. The necessary Sonostar apps should initially be available for Android, an iOS version will follow later. Qualcomm could achieve a big hit with its Toq (pronounced "Talk"), the first smartwatch to have a Mirasoi display - a field of micromechanical metal membranes with which a picture can be generated through targeted interference These colored mobile displays work purely reflective and are bistable, so they retain their image content even after the control voltage is removed. Although the display is always on, the watch should run for several days on one charge. Speaking of the battery: Qualcomm's smartwatch is charged wirelessly via WiPower LE. Initially, the watch is to be offered in limited numbers in the USA for around US $ 300 - as a second display for Android smartphones. The Toq's Mirasoi display measures 1.55 inches (around 3.94 inches) cm) and has a resolution of 288 X 192 pixels. With every new smartwatch announcement it becomes clear that the term is difficult to grasp, because many manufacturers are experimenting with very different approaches - in the hope that their solution will hit the nerve of customers. Because of the small batteries, the running time is currently the big issue for all smartwatches. And that depends above all on the display technology used. The Sony SmartWatch 2 made a good first impression here, the contrast of the energy-saving E-Ink display of the Sonostar with its 16 shades of gray was not yet fully convincing in the pre-production model - which is why the question arises as to what can be achieved in this regard before series production. Number one is the Toq's Mirasoi display, which you can almost speak of a colorful, fast e-paper. We looked at all the clocks we could get our hands on; You can access the resulting videos under the following link. (nij) www.d.de/1321 022 Sony's SmartWatch 2 (left) has a larger and higher resolution display than the current model: 4.06 instead of 3.05 cm and 220 X 176 instead of 128 X 128 pixels. The Sonostar has a black housing already the final desired shape, while a white, somewhat clunky pre-production version dominates rudimentary functions.22c't 201 3, issue 21

The Windows 8 device combines the 360 ​​degree foldable display of the consumer version with well-known ones from the Thinkpad series Advantages such as a good keyboard with trackpoint and a robust housing. In addition, pen input is provided on the touchscreen. As a special feature, the keyboard bezel protrudes a few millimeters from the housing when the display is opened beyond a certain angle so that the torso can lie flat without damaging the protruding keys and the trackpoint. The display measures 12.5 inches; it is available in variants with 1366 x 768 (1 25 dpi) and 1920 x1080 pixels (1 76 dpi). A matt version is also available, but presumably only as a pen version. The Thinkpad Yoga weighs 1.6 kilograms and is almost two centimeters thick. The 1366 version should be available in November from 950 euros.

The display of the Split X2 only shows 1366 x 768 points - compared to the competition, which mostly uses Full HD, this is meager. The plug-in keyboard houses an optional 500 Gbyte hard drive, a second battery and card reader, two USB sockets and HDMI. These features make the Split X2 more practical in notebook mode than many other tablets with a clip-on keyboard. If it is plugged in, the battery in the tablet first charges; On the go, the battery is tapped in the keyboard for this purpose. HP specifies a runtime of 10 hours for the combination; the tablet alone can hold out for five hours. The Split X2 weighs 1.03 kilograms, the keyboard dock 1.33 kilograms, both together almost 2.4 kilograms. Oow)

Current I EU Telecom RegulationRichard SietmannReform packageEU measures for a networked EuropeThe EU Commission has presented a draft regulation for the implementation of the digital agenda in Europe.But Brussels does not do justice to the claim to have solved the problem of net neutrality From "measures for the European internal market for electronic communications and for the realization of the networked continent", Brussels wants to overcome the patchwork of different telecommunications regulations in 28 national markets. According to the Commission, this is the "most ambitious reform of the telecommunications markets since liberalization over 20 years ago". From frequency policy to network interconnection and roaming, the legal framework for telecommunications (TC) that has been in force since 2009 is to be supplemented by an EU regulation in numerous individual regulations (see also the box on p. 28). In the regulation proposal, the Commission also presents its ideas for regulating network neutrality. It is about the problem that has arisen since the privatization of the formerly state-owned telephone companies, to what extent access network operators act as brokers between the end users - on the one hand the content providers, on the other hand the consumers - or whether they have to limit themselves to the non-discriminatory provision of network access and connectivity to other networks -The commission reads "as well as" and can be found in the section on end-user rights, among other things. "End users are free to access and distribute information and content via their Internet access service and to use applications and services of their choice," states Article23 on the one hand. The draft regulation defines the "internet access service" as a publicly accessible electronic communication service "which, regardless of the network technology used, offers a connection to the Internet and thus connections between almost all of the termination points connected to the Internet". For this purpose, it prohibits the blocking, slowing down, deterioration or discrimination of certain content or applications contractually agreed data speeds and volume limits. Exceptions to this should only be permitted within the framework of "appropriate traffic management measures" based on legal requirements, to protect the network, to combat spam and to cope with sudden traffic jams. On the other hand, the draft ordinance defines "special services" (such as IPTV, VPNs or cable TV) only establish a connection to certain content or end hosts Act as a broker and marketer of content and services. Article 23 expressly maintains its freedom to conclude agreements with content providers on the prioritized delivery of content "as special services with a certain quality of service or their own capacity". The regulation is intended to ensure that end customers are free to choose which way they want. In-EU Commissioner Neelie Kroes sees net neutrality in Europe secured by the draft regulation. Obtaining criticism from a sham. And Article 23 requires the operators that SpecializedServices "do not affect the general quality of Internet access services in a repeated or constant manner". What this means in concrete terms remains open; National regulatory authorities should be able to issue minimum requirements for this purpose. The lead commissioner believes that she has mastered the challenge. "We have no protection for net neutrality in Europe today," explains EU Vice-President Neelie Kroes categorically - "this proposal will ensure it." However, not everyone sees it that way. "Ms. Kroes has been promising us for years to anchor net neutrality at the European level", criticizes Markus Beckedahl from Netzpolitik.org, for example - but what she has just presented turns out to be a "sham". Jeremy Zimmermann from the French activist organization "La Quadrature du Net" describes the regulation as " As helpful as an umbrella in a hurricane ". Lever effect" The draft legalizes business models in which selected media offers, which would be throttled by the competition as an Internet offer, continue to have unlimited public access as a managed service, "says Christoph Fiedler, Managing Director of Media Policy at the Association of German Magazine Publishers (VDZ). Targeted service quality offers and content deals can in future be used as or lever for the market-dominant network operators to bring attractive content from the generally accessible Internet to their own "shopping mall". With Article 19 on "Assured Service Quality" for network interconnection, the Commission also wants to oblige all operators to provide quality classes for traffic exchanges Introduce border gateways - even smaller ones that may not want that at all. "It may well be", VDZ managing director Fiedler asks himself, "that the logic of the free market leads to the introduction of quality classes across networks, but why must politics then force the network operators to do so?" For the reform that is now pending, Brussels has chosen the path of the EU regulation the adoption by the parliament and the council will become directly applicable law and - unlike the 2009 TK guideline package - no implementation by national legislators will be required. First the EU Parliament deliberates, but there is not much time left in this legislative period: The last plenary session is scheduled for mid-April 2014, with European elections coming up in May.

current I EU Telecom Regulation The catalog of measures of the EU Commission Network operators who want to offer their services in several EU member states have so far had to obtain approval from each individual country. With the regulation for the implementation of the Digital Agenda, a Europe-wide authorization is introduced, for which a single registration in the member country in which the provider has its headquarters is sufficient. Their frequency sovereignty is to remain untouched, but the Commission would like to be able to synchronize the availability, the time of allocation and the duration of the usage rights of frequencies across the EU. By means of a consultation process, it wants to be given the opportunity to review the plans of the nation-state frequency administrations in advance of decisions. The aim is to create a uniform "European radio area" for mobile broadband services and planning security for operators operating across borders. Wireless LANs The use of public wireless LANs - such as WLANs in the license-free bands of 2.4 and 5 GHz - wants to make it easier There are restrictions for end users that prevent the cross-linking of access points or the sharing with other users, should these be lifted. Authorities and companies should be able to connect public hotspots to wireless LANs they use without being legally classified as providers of electronic communication services.In addition, the Commission would like to introduce general approval of small low-power access points that can be used in public spaces without additional approval procedures. In some EU countries, efforts are being made to introduce "virtual line unbundling" in the fixed network in the form of bit stream access to end customers, so that alternative network operators can use them And newcomers without their own local loops (TALs) get a cheaper alternative to renting individual TALs. In Germany, Great Britain and Austria, for example, corresponding work is underway under the designation "OpenAccess",. "Active Line Access" (ALA) or. "Virtual Unbundled LoopAccess" (VU LA). The regulation is intended to standardize the rules according to which the set drivers must grant each other this end customer access at the bitstream level - called "European Virtual Broadband Access". The Commission proposal specifies minimum requirements for this in an appendix. wise to reduce the surcharges for cellphone use in guest networks. The European Commission relies on a double strategy: Either the mobile network operators offer their customers EU-wide tariffs ("roaming at domestic prices") and are therefore released from the roaming regulation must take into account that in future customers will be able to conclude cheaper short-term contracts with local providers when they are abroad, without having to buy a new SIM card. Internalize contracts. However, some associations criticize the fact that this will likely increase the prices for domestic telephone calls and mobile Internet use. Consumer protection With a strengthening of end-use rights, the Commission wants to overcome the very different forms of consumer protection in the telecommunications sector. The differences would hinder the cross-border provision of services, they are expensive for the operators and unsatisfactory for the consumers, it is said to justify. Consumers should have a right to clearly formulated contracts with better comparable information and get extended rights with providers and Change of contract The change is to be facilitated by a "provider-led procedure" in that the new conclusion automatically leads to the termination of the contract with the previous set driver. The minimum contract term may no longer exceed 24 months and each provider must also offer contracts with a maximum duration of 12 months Contract extensions should no longer exist and open-ended contracts can be terminated free of charge after six months within a month The change requires the old provider to forward their emails to the new address free of charge for one year. "Assured Service Quality" products. At least three service quality classes are required for voice and video telephony, the distribution of audiovisual content and for data-critical applications.RoamingA central point in the harmonization of the internal telecommunications market is the abolition of roaming charges so that mobile phone calls in other European countries no longer cause additional costs -Enhancement of BEREC The objective of a European regulatory authority to implement its requirements had to be given up by the Commission in view of the resistance of the member states. However, the coordinating role of the "Committee of National Regulatory Authorities for Electronic Communications" (BEREC) is to be strengthened - for example through the appointment of a full-time chairman who runs the business for three years In addition, the Commission wants to be authorized to demand the lifting of measures against network operators operating across the EU from the national supervisory authorities if the regulatory requirements lead to conflicts with the market conditions in other member states.28c't 201 3, Issue 21
