Zero chance of getting back what has been looted
Technological lead in hard terms of process size has been handed on a plate to TSMC, with AMD in second place. In this time many large fortunes were taken out of intel through such devices as bonuses and share buybacks (directors inflating the value of their own share comp). A lost decade of under-investment won't easily be recouped, and once you start to serve up a company like cherry pie the actual useful employees will be too busy complaining at the size of their slice to make the heroic effort of even trying to save it. Carl Marx having a bad hair day there.
UK's AI fairy tale sets out on its yellow-brick roadmap
AI here is code for "bot farming"
Its quite annoying for those of those who do AI research that the term in relation to government is now code for farming twitterbots or generally manipulating the masses over social media. Really that sort of thing is not very impressive or interesting, although consequences can be dramatic, sure. Please call it what it is el Reg, rather than falling for the govts line that e-sneaking and social media trawls are "AI".

Re: The war is over, the empire is gone
Nazis are everywhere... worldwide more and more people are held in camps under appalling conditions for the sake of the political capital to be made by abusing them, or the fortunes to be made (in some cases) by appropriating their territory and assets. Uighurs, Mexicans, Sirians, Rohinga, Palestinians, I can't even be bothered to list them. Tyrranical and racist police states never went away and are in resurgence right now.

Geiger counters are so last summer. Lasers can detect radioactive material too, y'know
Might have saved Litvinenko
As I remember, the Russian assassins who did for Litvinenko didn't make any attempt to transport their polonium in an airtight lead box, so it would have showed up on one of these scanners. It would also have showed up on a Geiger counter, as the isotope they used is more than just a bit radioactive, but I guess maybe they aren't installed in British airports right now anyway.

Grumbling about wobbly Windows 10? Microsoft can't hear you over the clanging cash register
Local patch testing, 3rd-party antivirus & malware, real work all done in vms
We have windows 10 on some machines at work. To support this we need a dedicated server to host updates pushed from microsoft, a near-full-time staff member to test the patches and make sure they don't break anything, plus third party software galore (individually downloaded, not automagically pulled from a repo) to make the machines useful and keep them secure.
90% of users for these machines then do their actual work in a linux VM.

Lo and behold, Earth's special chemical cocktail for life seems to be pretty common
Bootstrapping actually seems to follow a maybe-necessary sequence
Biochemists (eg Kenji Ikehara https://ikehara-gadv.sono-sys.net/en/ and JT Wong https://www.ncbi.nlm.nih.gov/pubmed/1057181 ) have looked at the frozen-in evolutionary history of the genetic code together with the relative probability of (random synthesis/autocatalytic self-synthesis) for various amino acids and come up with a match - this shows that the arrival of the current ludicrously complex biological basics can be broken down into individually more probable steps, where a bunch of free-floating amino acids get pulled into a fragile self-replicating system which then develops them as as tools to make more of the same aa. Initial autocatalysis of poly amino-acids doesn't have stringent requirements on sequence or structure of the amino acid chain - a semirandom aa polymer can still have some catalytic activity to make more semi-random aa polymers.
Re: So, why don't we still have dinosaurs?
The code seems very redundant but the code table as it is gives certain very specific structural features which make (at least) recombination easier for certain specific sequences. In modern organisms this minor advantage is unimportant but in simpler beasts it may have been decisive in bootstrapping some of the complex but vital machinery such as ribosomes and recombinases. https://doi.org/10.1017/S0033583517000130
Early earth wasn't like current earth
One thing this article doesn't mention is that earth at the origin of life was very different than today, it had very little free oxygen, and was probably abundant in cyanide and other chemicals we consider toxic.
The current abundance of oxygen, as well as the details of the carbon cycle and numerous other bio-geo equilibria are down to the excreta of various mostly-tiny organisms. This is not necessarily some benevolent gaia-system: when oxygen became abundant in the earth's atmosphere it was toxic to the vast majority of the extant biota, and broke the greenhouse effect, causing a planet-covering super glaciation which lasted for millennia. Planetary chemistry could have followed many different paths, and certainly started in a very different place to where it is today.
Re: So, why don't we still have dinosaurs?
Everything alive on Earth today shares the same basic molecular machinery, implying a common ancestor. But yes, any of the previous mass extinctions could have been a full stop for some completely different lineage. Interesting thought. Dirty keyboard icon in case a new, more effective, ribosome has just evolved on it thus marking humanity's doom.
Re: So, why don't we still have dinosaurs?
New proto-living chemical systems capable of starting off a de-novo evolutionary tree may well be continually starting up in the tide pools and subterranean vents of Earth's oceans, and being enthusiastically eaten by the the teeming swarm of microbes which already live there.
What can you do when the pup of programming becomes the black dog of burnout? Dude, leave
Mucho very interesting literature here
The Tavistock in London has made a special study of burnout, at the individual level but especially with reference to the collective. The institute was directed to this task beginning with WWI, when it was noticed that entire units would lose the will to continue fighting, even as comrades in other divisions endured still worse horrors with a cheery grin.
This was an interesting start for me:

Boffin supercharges FPGAs with timing signal tweak
middle author not culpable apparently
The IEEE's withdrawal note states that only the first and last authors (Imran Ali Qureshi and Ghulam Muhammad Shaikh) are culpable in the plagiarism. The middle one, Fahad Qureshi, is apparently not to blame.
Its entirely possible that he was added as a co-author to give the paper a greater appearance of legitimacy and never actually read it. (Against the rules: he probably signed something to say he had).
Its also possible that Fahad Qureshi was bought onto the Swedish paper after it had mostly been written, to reflect some genuinely useful contribution that was in the Pakistani paper, which was not enough to give it legs by itself but which was worth bundling with the Swedish work.
Whatever the sequence of events its hard to image that there is much love between the Swedish group and the Pakistani group right now.
Smiley face for the poor SOB who worked on this for years while others tried to snatch the credit.
Following the train of events
Its quite fun to try and reconstruct what happened here.
The apparently non-culpable author, Fahad Kureshi, did a thesis on FFT optimisation in the Swedish group supervised by the same prof (Gustavsson). In his thesis he lists 10+ publications with Gustavsson on FFT optimisation, including hardware-level tweaks. Therefore he is no amateur and has the full confidence and respect of the Swedish group.
In the thanks list, he acknowledges "My friends and colleagues in Pakistan for their help and care..." and then goes further to mention: My friends... ___Imran Qureshi___ ..... for their kind help in proof reading my thesis.
So the first author of the plagiarising paper (unless its another Imran Qureshi, there are a lot of Kureshis/Qureshis about)..... proofread the thesis of a guy from the group delivering the original work. He didn't do a good job, its still has quite a few spelling and grammar mistakes.
Lets make assumptions:
(1) Imran (Q/K)ureshi asks Fahad Kureshi is he can lift an unpublished chunk of the thesis that he's written, saying yes I'll credit you for the work you've done.
(2) Imran's paper still doesn't have enough meat so he just follows the threads that he already has from Fahad's work and ends up with a duplicate of what Ingmarrson ended up doing under Gustavsson's supervision.
(3) Imran goes to his supervisor, Dr Gulam Shaikh, who is busy with teaching, underpaid and very stressed from the difficulties of life in Karachi. Ingmarrson's paper isn't out, so they publish, claiming to have a legit collaboration with Gustavsson's group, although not actually Gustavsson, which is unthinkable to the hierarchically-minded aryans over in Linkoping.
(4) Gustavsson points out that priority comes from first submission to a journal, not first publication. Despite (maybe) only having been somewhat cheeky, the Pakistani group are obliged to back down. Their mistakes were (1) Treading on Gustavsson's toes by working in a field he was busy in. (2) Using information from his (former?) grad student to steal a lead.
Fahad Kureshi will get a telling off for leaking, but most likely be forgiven.
Imran Kureshi and his boss are going to come in for a lot of hate, I would be interested if either of them reads this post if they could tell me how well I reconstructed this...
How the Facebook money funnel is shaping British elections
IT MATTERS
It really winds me up when people say that some shadowy force (corporations, civil service, illuminati blah blah) runs the country so why bother voting. An MP in charge of a parliamentary select committee or sitting in the cabinet or at #10 can have a huge effect on outcomes for the country and the world. We didn't have to fight the Iraq war, we didn't have to bail out the banks in 2008. Those were political decisions that could have gone very differently, and did so in other countries with different politicians warming the benches.

Re: Loved to Death
No need to assume anything AMBxx.... we can measure the lack of education, stats here:

Inferring unintelligence from a lack of education is of course dangerous with individuals, but holds very strongly when you look at statistics over larger samples.

Pair programming – you'll never guess what happens next!
Tried this by accident
I have a subordinate who buffed his CV a little and arrived with essentially zero knowledge aged 35 or so. I ended up sitting next to him at his desk typing in code for maybe 8 hours a week, and we developed a routine where he would correct spelling mistakes and remind me what file where things are defined in.
I'd credit him with supplying a 5% boost to my productivity, which is better than being of zero use (its not politically possible to sack him) as would otherwise be the case.
British trio win Nobel prize for physics
Sums up the history of UK science funding, and other things
Thouless moved to the US in the fifties to do his doctorate with the (German, somewhat Jewish) renowned nuclear physicist Hans Bethe.
The attractiveness of a venue for your research career is mostly determined by the environment: secure post, non-invasive bureaucracy, company of accomplished scientists you can hope to learn from.
Resources for research and a non-insulting salary are something but they are relatively unimportant. The UK is on a relatively good footing at the moment because the US has joined it in a race to the bottom in terms of a managerialistic ("work-like") culture.
Pass the 'Milk' to make code run four times faster, say MIT boffins
Sounds great call me when its in the OpenMP standard
This seems to address the big problem with OpenMP, which is that you can easily end up getting a net slowdown due to cores fighting over what is in the cache. If this is at all effective then the extra pragmas will/should get rolled into the standard very quickly.
Microsoft thinks time crystals may be viable after all
Its not complicated
Just a system which spontaneously settles into collective oscillation (like the quartz crystal in your digital watch). As far as I can see from the article the cool part is that any "clock drift" will self-correct, and that energy leakage will be approximately (not exactly) zero. So much woo-woo about time-loops and tardises sheesh
Nest offers its thermostat in three new pretty colors!
such hostility
The functionality is useful. Concerns about offclouding photos of your house are very legit, but most people really cannot be bothered running a home server and economies of scale are a thing.
Maybe the answer here is to design zero-maintainance home servers that can sit next to the boiler and take care of all this shite. Its not the path that nest seems to be taking, but already the average wi-fi router is also a NAS (its cheap enough to add a few gig of SS storage that many routers do so even in the expectation that 90% of customers won't even realise its there) and a few other things.
The first company to go down the route of designing low-cost low-fail high-security no-drm home servers for this stuff (home automation + NAS) should be a win. Cloud backup can and should be strictly optional, and strictly encrypted.
Trustmarque has been sold yet again – this time to Capita for £57m
monopoly, conflict of interest
Capita was recently delighted to announce that its near-monopoly on running the NHS has been still more strongly consolidated:
http://www.ft.com/cms/s/0/408bcd74-18bb-11e5-8201-cbdb03d71480.html#axzz4CHcl4nKu
in particular, it has a contract to advise the "commissioning groups" which decide what IT services to buy, while one of trustmarque's businesses is selling managed windows boxen to the NHS.
I wonder, having collected its advisory fee, which business capita will advise the NHS to buy/rent its PCs from?
