Raspberry Pi W Antenna Analysis Reveals Clever Design

The old maxim is that if you pay peanuts, you get a monkey. That’s no longer true, though: devices like the Raspberry Pi W have shown that a $10 device can be remarkably powerful if it is well designed. You might not appreciate how clever this design is sometimes, but this great analysis of the antenna of the Pi W by [Carl Turner, Senior RF Engineer at Laird Technology] might help remind you.

[Carl] used some fancy toys in his analysis, such as the awesome-looking antenna test chamber that his employer uses to test designs. He used this to measure two very interesting things; the radiation pattern of the antenna, and the efficiency. Simply put, the efficiency is a measure of how much of the energy you push into an antenna is emitted as RF radiation. There is always a little loss, but he found that the Pi W antenna has decent efficiency, with -3.5 dB losses at WiFi frequencies. That’s nowhere near as good as the stand-up antennas on your wireless router, but remember that the WiFi antenna on the Pi W is tiny compared to them: it is a small spot on the PCB made by removing several layers of copper, creating what engineers call a resonant chamber. That makes it a remarkable bit of engineering, keeping the cost down and using the copper layers that are already on the board to create the antenna rather than adding a new component.

The radiation pattern of the Pi W is also interesting. Because the antenna is located right on the PCB next to the HDMI and USB ports, you might expect that the signal would be much stronger in some directions than others. And you would be right: it seems that the metal shields of the two ports do block some of the radiated signals. However, it is worth remembering that WiFi signals also bounce around a lot, and other factors can influence how strong a connection is.

The final words of the analysis by [Carl] should be something that all hackers remember:

You can always learn things from clever designs and smart engineers. The amount of effort and creativity that has gone into this $10 computer is impressive—and the results speak for themselves.

Formula One's streaming service won't launch until next month

We're almost halfway through April, and Formula 1's streaming service hasn't launched as promised. The racing organization announced today that F1 TV will now be available next month ahead of the 2018 Gran Premio De Espana. Annual subscription rates are available for between $70 and $150, or $8 - $12 per month. "The service will be priced according to market," the announcement reads.

The higher-pried "Pro" tier will offer live races and access to cameras on all 20 drivers' cars in addition to what sounds like a picture-in-picture mode for viewing multiple feeds at once. As previously announced, all pre-race practices, qualifying races and pre-and-post race press conferences will be streamed as well. The FIA Formula 2 Championship, GP3 Series and Porsche Supercup will be added later in the season.

The lower-priced option translates to extended highlight reels and "unprecedented access" to F1's deep archives of historic video. As far as live programming goes, however, you'll be limited to race timing data and radio broadcasts, according to F1. That'll launch on a "near-global" basis alongside Pro next month.

For now, there's a small, closed beta that'll run through the Heineken Chinese Grand Prix and Azerbaijan Grand Prix. To see if you're in the coverage zone, hit the source link below.

Need something to fill in the gaps until F1 TV begins broadcasting? The F1 eSports league starts competition today, and you can all but guarantee that the proceedings will be streaming on Twitch.

Google Is in Talks to Buy Nokia's Airborne Broadband System: Bloomberg

Google is in advanced talks to buy Nokia's airborne broadband system, Bloomberg reported on Tuesday. Google would use Nokia's system, the report claimed, to tap into new services and reach more users by offering in-flight high-speed internet. From the report: Nokia's technology could help Google offer a faster alternative to existing Wi-Fi on airplanes, said the people. Talks are advanced and an agreement may be reached soon, the people said. A final decision hasn't been made and the companies could still decide against a deal, the people said. Nokia's LTE A2G cellular-based system creates a direct link between an aircraft and the ground instead of bouncing the signal off of a satellite, enabling in-cabin high-speed internet services using Wi-Fi, according to its website.

"PUBG" Ransomware


Before you forget that it is not April Fool's Day, this actually looks to be a real thing. This PUBG Ransomware does not go in search of your hard earned cash, but rather will decrypt your hijacked files if you play PUBG for an hour (actually you just have the run an executable for 3 seconds). It does however just give you the key to decrypt as well if an hour's worth of PUBG is not your thing. Bleeping Computer makes no mention of how this is getting around. All press is good press? Not so sure about that. Thanks @cageymaru.

Once a user plays the game and the process is detected, the ransomware will automatically decrypt the victim's files. This ransomware is not too advanced as it only looks for the process name and does not check for other information to confirm that the game is actually being played. That means you can simply run any executable called TslGame.exe and it will decrypt the files.

File Manager for Windows 10 is now available as Microsoft open sources winfile code

Cast your mind back several years and you'll remember Windows 3.0 and earlier. This was when Microsoft started to being home computing to the masses, and for anyone raised on modern Windows, the lack of Start menu, taskbar and other components makes the operating system seem antiquated and unusable. But use it we did! Back then, there was no File Explorer, but File Manager instead -- and it's something that people sometimes feel nostalgic about. A couple of days ago, Microsoft open sourced the File Manager code, and a Windows 10 version has been released. The source code -- as… [Continue Reading]

How GDPR Drives Real-Time Analytics

New reforms under the General Data Protection Regulation (GDPR) started as an attempt to standardise data protection regulations in 2012. The European Union intends to make Europe “fit for the digital age.” It took four years to finalise the agreements and reach a roadmap on how the laws will be enforced.

The GDPR presents new opportunities as well as difficulties for businesses, digital companies, data collectors, and digital marketers. On the one hand, these regulations will make it more difficult for businesses and data mining firms to collect and analyse customer data for marketers, while on the other, they will present an opportunity for data collectors to innovate and enhance their techniques. This will lead to a better collection of more meaningful data, as customers will be directly involved.

Understanding GDPR

The GDRP will go into effect on May 25, 2018. It will apply to all organisations and businesses that process personal and marketing data from European residents. 

There are six underlying principles of GDPR.


Organizations must ensure that the personal data of users is processed transparently, lawfully, and fairly.
Personal data of users must only be collected for explicitly specified and legitimate purposes.
Data collectors must only gather limited amounts of personal information that is adequate ...

Try Google's New OS In Your Browser

Google has been fighting with itself for a long time having Android and Chrome OS overlapping each other, and now Slash Gear is reporting that Google is apparently working on a third wheel. "Andromeda" was a rumor that had started from people thinking that Google would merge their two current operating systems together, however Google Fuchsia is a new OS built from the ground up that you can play with today in your browser. So using the demo, half of it doesn't appear to be working, and there is really nothing that it can do to show itself off. However it makes me curious *tinfoil hat on* I wonder if this is made to be some sort of Cloud browser, even more so than Chrome OS is, and this is less of a demo and more of a test? Either way, Google needs to stop spreading itself so thin in my opinion. The user interface for Fuchsia OS isn't really a secret, but until now it has been mostly revealed in bits and pieces of code and nothing but the most hardcore of developers or enthusiast can try out. This demo, which can be run on any browser, whether desktop or mobile, gives even curious onlookers a chance to see what Google has been cooking in private. Discussion

Clear Linux Shedding More Light On Their "Magic" Performance Work

If you have been a Phoronix reader for any decent amount of time, you have likely seen how well Intel's Clear Linux distribution continues to run in our performance comparisons against other distributions. The developers behind this Linux distribution have begun a new blog series on "behind the magic" for some of the areas they are making use of for maximizing the out-of-the-box Linux performance.

Their first post in their "behind the magic" series is on transparent use of library packages optimized for Intel's architecture... While they are optimizing for their own hardware as one would expect, let's not forget, Clear Linux does run on AMD hardware too; they are not doing any voodoo magic, which is why it pains me that more Linux distributions have not taken such a stance for better out-of-the-box speed. In fact, it runs on AMD hardware darn well as we have shown with our Ryzen and EPYC benchmarks. Obviously Intel tweaks their software packages for their own x86_64 CPUs, but even when testing on the AMD hardware Clear Linux tends to perform the best in terms of out-of-the-box performance and that Intel isn't doing anything to sabotage the performance otherwise.

With this first post it's explained how as of Glibc 2.26 there is support for a single binary library that can be optimized for multiple different platforms and the optimal platform selection is handled at run-time. This can be used just not by Intel but other vendors/architectures too, but sadly so far the adoption of it seems to be fairly minimal. Intel developers are also using this Glibc functionality to tune their performance for Xeon Phi hardware.

If you are interested in more of their technical information behind their use of this Glibc feature for exploiting more performance out of the software, see the latest post at

ClearLinux.org

. Next up they are expected to talk about their PGO tuning and boot time optimizations.

1.1.1.1: Cloudflare's New DNS Attracting 'Gigabits Per Second' of Rubbish

An anonymous reader quotes a report from ZDNet: Cloudflare's new speed and privacy enhancing domain name system (DNS) servers, launched on Sunday, are also part of an experiment being conducted in partnership with the Asia Pacific Network Information Center (APNIC). The experiment aims to understand how DNS can be improved in terms of performance, security, and privacy. "We are now critically reliant on the integrity of the DNS, yet the details of the way it operates still remains largely opaque," wrote APNIC's chief scientist Geoff Huston in a blog post. "We are aware that the DNS has been used to generate malicious denial of service attacks, and we are keen to understand if there are simple and widely deployable measures that can be taken to mitigate such attacks. The DNS relies on caching to operate efficiently and quickly, but we are still unsure as to how well caching actually performs. We are also unclear how much of the DNS is related to end user or application requirements for name resolution, and how much is related to the DNS chattering to itself." The Cloudflare-APNIC experiment uses two IPv4 address ranges, 1.1.1/24 and 1.0.0/24, which have been reserved for research use. Cloudflare's new DNS uses two addresses within those ranges, 1.1.1.1 and 1.0.0.1. These address ranges were originally configured as "dark traffic addresses", and some years ago APNIC partnered with Google to analyze the unsolicited traffic directed at them. There was a lot of it. "Our initial work with it certainly showed it to be an unusually strong attractor for bad traffic. At the time we stopped doing it with Google, it was over 50 gigabits per second. Quite frankly, few folk can handle that much noise," Huston told ZDNet on Wednesday. By putting Cloudflare's DNS on these research addresses, APNIC gets to see the noise as well as the DNS traffic -- or at least "a certain factored amount" of it -- for research purposes.

Facebook Released New Tool to Delete Your Data

In the wake of the ongoing Cambridge Analytica scandal, Facebook is releasing new tools to make privacy settings, as well as deleting your data easier to find. The system is focused around a new Privacy Shortcuts menu, where users can can control the data Facebook collects in just a few taps, instead of "having settings spread across nearly 20 different screens." Seems a bit too little too late in my opinion. And it's tough to say whether or not admitting that the old system was convoluted will help or hurt them as Zuckerberg goes to testify before Congress. At least is better than the "Deal with it" we got from them yesterday. We've heard loud and clear that privacy settings and other important tools are too hard to find and that we must do more to keep people informed. So in addition to Mark Zuckerberg's announcements last week - cracking down on abuse of the Facebook platform, strengthening our policies, and making it easier for people to revoke apps' ability to use your data - we're taking additional steps in the coming weeks to put people more in control of their privacy.

Bring your own Linux to Windows

Icon

After starting with Ubuntu, Microsoft has added a number of Linux distributions to its Windows Subsystem for Linux (WSL) Linux runtime environment. A Windows machine can simultaneously offer an Ubuntu, SUSE, Debian, and Kali "personality," providing users with a choice of the different distributions' preferences and package management.

But if your distribution isn't yet available or if you want a Linux installation that's customized just the way you like it, there's now an answer: Microsoft has an open source tool for building your own Linux package. The tool is aimed at two groups: distribution owners (so they can produce a bundle to ship through the Microsoft Store) and developers (so they can create custom distributions and sideload them onto their development systems).

Neat.

Logitech's G Pro headset is built for eSports

With the new G Pro headset, Logitech set out to make something that gamers could wear for hours on end, without getting fatigued. It's a fairly straightforward pair of headphones: It only offers stereo sound (no fancy surround option), and it relies on an analog audio connections. Instead of the sports mesh headphone material found on Logitech's other gaming headsets, though, the $90 G Pro sports soft leatherette. The company claims it offers 50 percent more sound isolation than before, but more importantly, the new material simply feels better. (The previous covering made my ears feel a bit itchy after a few Overwatch matches.)

The headphones feature Logitech's Pro-G drivers with a slightly more aggressive sound profile than last year's headsets. While I found the G433 and G533 to sound a bit flat, the G Pro accentuate bass, which makes plenty of gaming moments feel more satisfying. Some music fans prefer a neutral sound profile, but when it comes to games, that tends to sound dull. The G Pro comes with a removable microphone, which features noise-canceling and better sensitivity than past Logitech offerings. You'll need a separate microphone jack to take advantage of that feature, which could be a problem for some gaming laptops.

Logitech says it developed the G Pro based on feedback from eSports players, and it shows. In addition to the leatherette ear coverings, you've also got microsuede replacements in the box. While I missed the useful noise separation from Logitech's surround sound headphones, the G Pro still sounded excellent. I could easily make out the careful footsteps of other players looting gear in Playerunknown's Battlegrounds, or enemies creeping up behind me in Overwatch. I also found myself paying more attention to games than with Logitech's previous headsets, thanks to the improved sound isolation.

At $90, the G Pro sits in the middle of Logitech's gaming headphone lineup, but they're a solid pick if you're looking for a high-quality wired option. You'll be able to snag one of your own in April.
