Location: for most locations, the main factor was getting the antennas lined up. The researchers said they got between 800 and 900 Mbps TCP throughput so long as line-of-sight was maintained: putting the transmitter and receiver around a corner from each other spoiled the performance.“High-throughput 60GHz communication is feasible at various locations typical of an indoor WLAN environment but strongly point to the importance of the relative orientation between the Tx and Rx antenna arrays”, they write.Distance: Interestingly, because of the wireless kit’s use of beam-steering and MIMO, distance effects are more complex than a linear collapse in throughput. Setups that went from nearly 1 Gbps at close range and zero at around 100 feet (30 metres) could recover as far as 500 Mbps at greater distances.Analysis Intel launched its 6th Generation “Skylake” Core processors at IFA in Berlin last week, and is desperate for you to upgrade your PC. But has the Intel and Microsoft alliance done enough to drive upgrades and new sales?

First, a quick recap on what Intel launched. The company announced 48 6th gen Core processors. The line-up is confusing but the gist of it is as follows.Intel is retaining the Core i3, i5, and i7 brands indicating “good, better, best” according to general manager Kirk Skaugen, who spoke at IFA. The Pentium brand also continues as a budget option.The processors are also distinguished by their series. The new range offers:As you would expect, the Skylake series improves both performance and power efficiency. Intel claims up to 60 per cent better compute performance from a Core i5, and up to 60 per cent lower power consumption for an H-series CPU.Intel’s new 500 series graphics have hardware support for decoding H.265 4K video and here the claim is for up to 40 per cent better graphics.Not all prices are announced, but they range from $623 for a quad-core Xeon E3-1535M v5, to $64 for a dual-core Pentium S series G4400T.As part of its IFA push, Intel was keen to talk down the value of old PCs. “There are over 500 million computers in use today that are four to five years old or older. They are slow to wake, their batteries don’t last long, and they can’t take advantage of all the new experiences available today,” said the press release.

Intel has worked with Microsoft to optimize Windows 10 for Skylake and vice versa, said Skaugen. The real-world benefit, aside from thinner devices with longer battery life, is shown in features like resume from sleep in less than half a second, and built-in game recording so you can show off achievements to friends. Another key feature is Windows Hello, authentication through face recognition, and Intel showed the system successfully differentiating between identical twins.So far so good; but will improved processors and Windows 10 revive the PC market, which declined 9.5 per cent in the second quarter of 2015, according to figures from Gartner?At IFA Microsoft had its own stand – unlike 2014 where it held a separate press event in Berlin – and the company’s OEM VP Nick Parker gave a keynote on Windows 10. In addition, key OEMs including Acer, Asus, Lenovo and Toshiba were present to show their new ranges.

Toshiba, for example, was showing the Satellite Radius 12, a rather lovely 12.5" notebook/tablet that has 360⁰ flip, 4k display on some models (3840 x 2160, 362ppi), RealSense camera for Windows Hello support, 10 finger touch, 6th gen Intel Core processors up to Core i7, 2 USB 3.0 and 1 USB 3.1 Type-C port (10 Gbps data transfer), up to 512GB SSD, 8GB RAM and of course Windows 10. Pricing was not available but rumoured to start from around $900.Another example is the Lenovo Mix 700, which echoes Microsoft’s Surface with its kickstand and detachable keyboard. This 12" device has a display up to 2160×1440, RealSense camera for Hello, and up to a 6th Gen Core m7 processor.Asus showed off its 17.3" ROG G752 gaming laptop, with 6th Gen Intel Core i7 CPU, DDR4 RAM, an option for 4K 3840×2160 display, USB-C / Thunderbolt 3.0 port, and NVIDIA GTX 900M series graphics.Of course there were the references to the meerkats who sell insurance, but lots of people looked at the creature’s hands along the lines of Andy Non: “Hey, who swiped my keyboard?” He also entered “But, the guy I saw sneaking out of the office with all our computer equipment said he’d replaced it all with virtual kit in the cloud.” , and “Hey guys, we’ve won the contract for the outsourced ISPs customer service department.”

Getting three mentions and not winning. He’s going to be peeved.Michael Hawkes saw the meerkat tapping its fingers while watching a live stream: “C’mon, Tim. Get to the good part already. One more thing! One more thing! One more thing!”Shame it was such a disappointment when Mr Cook got there.A pop at Apple shows that Ben Burch knows how to ingratiate himself with The Register: “Welcome to the Genius Bar! Why yes, we at Apple have a workplace diversity policy. Why do you ask?” , but it’s not enough to win.Fading raised a smile with: “After manually searching his complete directory tree, Geoff was most perturbed to discover his pron collection had been removed….”John Stabler offered: "I’ve been through this Madison log three times and I still can’t find any women."Thecowking has a better fauna joke with: “OK so I’ve been working on this branch, how do I commit it?"Other captions we liked were BQuatermass: ”New photo reveals the years of indoor living are taking their toll on Julian Assange” , Andy 73: ”You went to the lengths of hiring a real meerkat, but you’re going to CGI the laptop in? I’m RADA trained, darling, of course I can type!” And K.o.R with: ” The latest round of cuts finally affects BBC News.”

With an acknowledgement to last week’s picture, Fruit and Nutcase says: “So the Spider gets the Girl and I get the Log”. Continuing the “I’m reading this at work theme” were dasbnau (”Sysadmins everywhere fear for their jobs as scientists have now successfully trained meerkats to read logs, provided they are written in Braille”) and Barely registers (”Hire me as your tester – I eat bugs for breakfast”). Not to mention MAF: ”Sergei hated hates Helpdesk Fridays – all other meerkats on long liquid lunches and HE gets ‘lumbered’ with watching all the logs…”But the winner isn’t – as much as we like them – a techie line. It’s one that combines themes. Drumroll, please! The winner is Come to the Dark Side with: ”As the Gocompare singer walked past below, the meerkat gave the log a gentle push…”Well done Mr Dark Side. Your so-dark-it’s-black hard disk will be on its way to you. It’s now time for someone else to win a 6TB Western Digital Black drive.Correction Be careful with your Wi-Fi things’ MAC addresses: an Iowa cop wants to sniff hardware addresses to turn up stolen goods.

In a move that opens up a whole new world of "swatting," Iowa City’s The Gazette reports that city officer David Schwindt has created software to go war-driving for MAC addresses.He calls the software L8NT (oh, "latent," l33t-speak from a policeman no less), and with a suitable antenna, it will try to match any MAC addresses it encounters with "known stolen goods."Schwindt acknowledges that people might not have ever noticed the MAC address of their laptop, desktop, tablet, mobile phone, refrigerator, smart TV, or broadband router. Of course, if the Wi-Fi is turned off or the device is powered down, it’s not going to be visible.The Register notes that while MAC addresses are assigned on a unique basis by the IEEE, they’re no longer immutable, meaning any tech-savvy crook with time to spare can hide the provenance of stolen goods. Then there’s ploys like Apple’s decision to randomly change iThings’ MAC addresses, which Cupertino implemented in iOS 8 as a way to make it harder to identify devices connecting to public WiFi networks.

Schwindt promises that his software doesn’t look for any personally sensitive information while it’s scanning for contraband MAC addresses, but could create another problem if a malefactor with the right information created a new "swatting" attack by entering a target’s home gateway via the nearly-always-unchanged default password, then giving it a MAC address that will interest the police.The Gazette reckons the officer hopes to patent L8NT, which looks a bit of a stretch since "reading MAC addresses" is a pretty fundamental networking capability. Correction: A reader has taken issue with the phrase "MAC addresses are no longer immutable", writing: "Actually, the ability to change the MAC address was mandated by the original spec, back when it was DIX (DEC-Intel-Xerox) Ethernet. DECnet Phase IV changes the system’s MAC address to its network/node address."The US Federal Trade Commission (FTC) has fired a second shot at the FBI over its demand for backdoors in encryption systems.

Following a blog post last month by the regulator’s CTO in which he outlined why he was glad to have strong firmware encryption after his laptop was stolen, today FTC Commissioner Terrell McSweeny has also outlined why encryption is a good thing – and carefully suggests that introducing a way to undermine it may not be such a great idea."Now, more than ever, strong security and end-user controls are critical to protect personal information," McSweeney wrote in a blog post on Thursday.She goes on to highlight areas where strong protection of data is vital going forward: the "internet of things" where "addressing privacy and security is vital to achieving that potential"; the vast databases that companies are creating but which need to be secured; and products such as smartphones that store more and more of our personal information.She also wades into the disk encryption area seemingly in full support of it: "Disk encryption can protect information stored on the hard-disk from unwanted access, and hardware passwords essentially prevent machines from being used without the password. Using these tools can also make it easier for consumers to recover lost or stolen devices."

Then comes the shot at the FBI and the NSA – which have both argued in recent months for special access to encryption systems so they can see what is going on globally – something that technologists, tech companies, and Senators have been less than excited about."Encryption and end-user protections can raise issues of access for law enforcement," McSweeney notes. "Some argue that data storage and communications systems should be designed with exceptional access – or ‘back doors’ – for law enforcement in order to avoid harming legitimate investigative capabilities. However, many technologists contend that exceptional access systems are likely to introduce security flaws and vulnerabilities, weakening the security of products."She notes that this argument is "hardly new," but argues things are a little different these days: "What is changing is the extent to which we are using connected technology in every facet of our daily lives. If consumers cannot trust the security of their devices, we could end up stymieing innovation and introducing needless risk into our personal security. In this environment, policy makers should carefully weigh the potential impact of any proposals that may weaken privacy and security protections for consumers."

The fact that this argument comes in the form of a blog post on a third-party site is a sign that the regulator has no real jurisdiction over what the FBI does or does not do, and that the FTC does not have a formal position on encryption, but it is a clear sign that there will be some significant opposition within the government to forcing backdoors into products. Feature The other week a Viewsonic VX2475Smhl-4K monitor, boasting a 3840×2160 resolution running at 60Hz – though only 24-inches of it – shows up at my door. I’m happy as a clam until it dawns on me that this isn’t a job my faithful little NUC, the Gigabyte Brix Pro, is up to. I was going to need a rig and a half, probably costing more than my last two cars combined, to make use of this number of Pixels Per Degree of Vision (PPD).With HDMI 2.0 and DisplayPort 1.2a, Viewsonic’s VX2475Smhl-4K monitor is cheaper than a UHD telly but is a 24-incher enough?
Just when I thought I’d have to send the Viewsonic 4K monitor back, without witnessing The Witcher 3’s glorious sunsets and craven hags in four times as many pixels as usual, a chance encounter with the chaps from Overclockers UK at a Kingston HyperX gaming event put an end to my woes.Water cooled and to die for, I was sent the beef cake Infinity Vesuvius gaming PC powered by a quad-core Intel Core i7 4770K overclocked to 4.7GHz, with 16GB of RAM.
