I think the point about using in Python is that many of the users of HPC are scientists with no formal training in programming. Python has several libraries like NumPy that have made it popular in diverse scientific domains and the are companies that also serve and support them. I think the combination is what continues to make it a popular language for scientists. CERN has some nice graphics that illustrate the increase in Python code once the code for heavy-lifting (usally in C++ or FORTRAN) has been written. Benedit Hegner covered this in his keynote at the German Python conference last November. An hour long and in German and thoroughly entertaining.
Talk about apples and moonrocks
ARM confounded analysts during its fourth quarter growing sales by 19 per cent while chip giant Intel saw revenues down 3 per cent compared to a year ago.
Even with a slight drop Intel's profits are still enormous.
And then further down "Intel is throwing Atoms under ARM's wheels". Er, no. While Intel has indeed got Atom's to impressive performance/power levels so that the couple of phones with them compete favourably with ARM based stuff, the chips are still significantly more expensive than ARM chips and depend on Intel's better fabrication techniques.
Of course, ARM faces risks in the future. But so does Intel and, as Intel insists on being a manufacturer those risks are higher - sinking billions into a new fab is considerably riskier than trying out a new chip design. The rewards of success are also higher but those fabs just get more and more expensive to build.
Next to the fabless versus fab is also the difference in business culture. ARM's culture of co-operative competition amongst its customers and occasionally with them (Qualcomm, nVidia, PowerVR) and Intel's attempt to monopolise through instruction set. AMD only exists because IBM insisted that Intel licence a second supplier of x86. ARM's model is more in tune with component suppliers in other industries.
As for servers: there is now very little difference between Intel's CISC and ARM's RISC. Intel went RISCy with the Pentium and everyone has been adding instructions to their chips since MMX. ARM still gets more done with fewer transistors. Servers are likely to profit from exactly the same kind of commodification of components that has benefited Intel over the last 15 years. x86 has remorselessly gained market share from Power, SPARC, MIPS, etc. proving that new chips have a chance. This has meant vastly improved toolchains and compilers in the process from which ARM stands to benefit and the APUs of AMD and nVidia are starting to point the way: yes, a single instruction makes life easier for the compiler but if you can offload number crunching to GPUs then you will just get so much more bang for your buck. If ARM's big.Little architecture can demonstrate this kind of switching in real life then we can expect hybrid servers to really take off. x86 translation can be provided in hardware if necessary as the designs for the necessary silicon (Transmeta) already exist.
But it is also simply naive to put ARM up solely against Intel. Unless Intel goes fabless they are not competitors. Rather Intel is competing increasingly with nVidia, Marvell, Broadcom, Qualcomm, TI, Samsung, et al. and the competition will increase as the PC market fails.
Re: But, But
Two things - RSS has no push mechanism and polling is resource intensive; but I think the real reason for people staying away from RSS is the inability to forward stuff to the friends with important comments like "OMG!", "LOL!", etc.
Also a leaky nuclear plant wouldn't be very efficient and that wouldn't be very German would it
Oh, I don't know. The nuclear plants here don't have a particularly good record for efficiency just for making money for the owners which they do pretty shortly after being turned on. Or even after being turned off: we're looking at claims from up to € 20 billion from the owners about them being closed early. Against that background it's hardly surprising that the current environment minister is keen to talk absolutely anything else!
Re: No AMOLED
AMOLED is awful, in my opinion
And I prefer the higher contrast, … the point I was making was about the suitability outdoors which is a sine qua non for me. I wear polarised sunglasses which make LCDs compare even worse.
The blue does degrade overtime, but my phone is nearly three years old and still looks fine. Power consumption is typically than LCD higher when looking at items with lots of light colours (whites, yellows, greys, etc.). This is counterintuitive as the same process is being used to create light in both circumstances, LED-backlit LCDs using arguably more. It's to be hoped that the process engineers will continue to chip away at that, thought to have been slated for the S4 but apparently now due to make its debut with the the Note III.
Re: No SD card??
HTC is segmenting the market with the One X, V and S. They all have pluses and minuses but nothing has them all with the X seeming to fail because it doesn't do SD cards.
I actually think HTC have a point about not offering removable storage because, at the file manager level it might confuse. But for most people using media via apps that shouldn't be too much of a problem.
I don't think that AMOLED is a merely matter of choice, the screens are also significantly easier to read in bright sunlight. That SD card, and a dedicated camera button are what are keeping me on my Samsung Wave, which nearly three years in is still giving excellent service although it looks like the (removable) battery should probably be replaced.
It could have been worse
I've voted Liberal all my life, but didn't vote for …
If it's any consolation, if wasn't a coalition it would have been so much worse.
While I appreciate the sentiment I have to disagree with the statement: they have both a majority in parliament and also an absolute majority of votes cast. In British terms that's an unusually strong mandate as many recent governments have had majorities in parliament with well under 40 % of votes cast.
Re: Cisco is the problem, Skype is good enough
I've had lots of problems with video on Skype and wouldn't recommend it for corporate environments where the video certainly isn't good enough to go on a big screen.
Re: Do they actually pay up?
Full details should be available from OfCom or the ICO. But, in general, it's a fine so the money should go into a pot which might be used to provide compensation for victims. For the fairly obvious reason of avoiding people trying it on you don't get money for reporting alleged abuse. If the regulator determines that abuse has taken place then it might be possible to sue for damages, though one of the reasons for the fine-based approach is to avoid suits attempting to obtain excessive damages. I hate nuisance calls and always report them*, fortunately we don't get many in Germany, but they do not generally impose a significant cost. One of the things they do here if someone is adjudged to have committed abuse is to cut their, and by extension, their provider's access to the telephone system. I suspect this, as much as the higher fines introduced last year, is a good deterrent.
* to do this don't slam the phone down, however tempting, but note the details of the call. If there are a lot of calls then you can get the phone company to add a trace, this costs money which may or may not be claimed back, but will allow them to establish the originating network.

It seems that Google has finally got round to providing some of the added value search results that Cuil was trailing a few years ago in a sidebar.
Re: "culling little-used or unprofitable products"
I suspect 500,000 really is a small number where user accounts are measured in the hundreds of millions. But I suspect that isn't the point. Any such service that Google offers binds resources to maintain and run it. Where is the pay off?
Re: Once bitten...
This is the internet generation which has the memory of a goldfish and the attention span of a kitten.
Android into maintenance mode?
Sounds more like Pichai is being pulled off an unimpressive product (Chrome OS). Maybe he's being given the resources to scale Android up for notebooks, maybe they just want to back port the web app code to Android.
Android is more or less "done" so it makes sense to move Rubin onto something new to keep him interested.
Re: So what, indeed...
Except when they don't
For distance you have to use fibre because of the invariable ratio of power to distance squared and this limits you to light frequencies, by no means all of which are currently being used.
Radio propagation is well understood and, while, there are still plenty of bands available (the ITU carves up spectrum in not the most efficient way) you have to trade bandwidth for propagation.
The developments are complementary and impressive in their own right. Squeezing more out of an existing underwater cable is cheaper than laying a new one. Reducing power consumption while boosting data transmission will be welcome along the chain: in the server but also in the switches of the various NICs.
With a bucket of salt
Not including the market for Google's paid for mail and office software is a gaping hole. Actually, it's easy to pull the whole thing apart. And, as any fule no: it's not revenue but margins that matter. It wouldn't surprise me to see IBM making more than IBM from what it provides.
Amazon's services are popular and have enabled a raft of services. But it's not suited to every task and gets quite expensive if you use a lot of computing power.
Re: a sad day
Is this yours?
I use Podcatcher.
This is irksome because Flash is a prime target for targeted attacks and asking consumers or corporate users to turn it off, like Java in the browser, isn't easy because the technology is so widely used on the web.
I humbly contend that it is not as irksome as having the machines compromised by an exploit. I, for one, welcome Adobe's frequent release: better patched than gaping. Corporates can usually disable plugins by policy.
Re: Standard smug response.
And in Opera I have to click on plug-ins to run them. Doesn't that make me clever? However, how am I going to know in advance whether a particular item is compromised or not?
It depends on the nature of the exploit as to whether it can fixed quickly or not. Both Chrome and Firefox have extensive automated testing setups so there is no reason why they can't push out patches quickly. For details on what they have patched see the release notes.
Even Microsoft no longer encourages its use. It is now pretty much limited to providing the DRM for streaming services.
Re: Prize funding?
HP wanted the bragging rights and MS prefers to pay shills to write on forums that everything is hunky-dory. I think Google has an open policy for Chrome bugs and, of course, has just closed the competition for Chrome OS which had a measly $ 3 million as prize money.
Re: Wrong place
Why not hold it in Vancouver and it's simply naive to think that hackers are only in Russia and China. There are plenty all over including Israel and the US or doesn't the name Stuxnet mean anything to you?
Re: Surface Pro
And? They've still managed a zero-day in only those few months. It's still cherry-picking the figures that suit. I think OpenBSD still has the best record but I don't think you'll find anyone on the security team there thinking they have a truly bullet-proof system.
Re: Surface Pro
It is worth noting that Windows 8 has one of the lowest vulnerability counts versus time of any current OS, as does IE 10
No, it really isn't worth noting. Not been on the market for six months and not getting a great deal of use. Expect the number of known vulnerabilities to rise as more chumps are forced to use it.
All systems have vulnerabilities and an open approach to dealing with them is far more important than cock-crowing about the numbers.
She's gotten fat, so I think we can forget the sexy bikini version of her, unless she REALLY takes up some Hollywood miracle diet
You know I can't help but find that quite sad. I've always found her to be very pretty - she has a beautiful face and eyes and well curves - and is in her mid-fifties so not much older than Harrison Ford back then, if my back of the wank-mag calculations are anything to go by, certainly not past it. I'm sure the Lithium doesn't help with the weight but it doesn't matter that much, surely?

Re: It all depends on the water!
True. I have to filter the water here because it has so much bloody chalk in it (Rhine filtration method) that you just get a cup of scum if you don't. PG is my preferred - nice notes of Assam but not as strong as others and I much prefer using a pot for optimal taste. Don't have a fancy pot just steel with a wooden handle that's done about 50 years service. Metal pots don't really need warming but need tea cosies. Avoid "tea lights" at all costs which are the devil's work designed to sour the blessed beverage.
For Lester's test - a good strong cuppa goes great with a bacon sandwich on a cold. You might also want to see what goes well with your favourite biscuit - Rich Tea for me, I won't let Digestives in the house - or cucumber sandwiches if you're expecting company.
Re: Fine, but......
Where does the money from fines normally go?
Deutsche Telekom reckons the more-paranoid should stick to encrypted wi-fi networks
These are the norm in Germany because of the risks associated with running open networks - you might be held liable for any misdeeds carried out by someone using your network. Doesn't stop man-in-the-middle attacks on hotspots such as those provided by Deutsche Telekom on the trains.
Re: Chromebook is doing what Surface was supposed to do...
It's normally only worth checking whether he's taken his medication or not. And maybe to remind him to attend therapy, you never know: there may be hope.
On a related note it seems we're likely to be spared Matt Asay's dribbling. Wondering who El Reg will get to replace him. Personally I'd welcome a return of Ashlee Vance's column. Didn't always agree with him but could usually follow his arguments.
Intel in China
Although it's highly unlikely that Intel's chips will find their way into phones from those two market leaders, The "design win" with ZTE might help it get some traction in the fast-growing Chinese smartphone market.
Yeah, so a a premium price chip like the Atom is really going to help ZTE take on all-comers in a market defined by price?
Despite the fact that some of the Intel-based phones, particularly the Motorola, seem quite good, Intel is starting to look like quite a slut touting all these co-operations. No doubt they'll be touting their 100 % market share on Mars next.
Intel's silicon is not in doubt, but their licensing terms are: how can manufacturers who adopt Intel and pay the normal rate hope to compete against the legions of the ARMy who chips are, well, cheap as chips?
PDP-8 any good?
Used to have one in the garage but I think it's now gone to a better (less damp) home.
Re: Always look on the...
I'm English but I still find it offensive the way you refer to "Gross Germany".
Investment and deregulation required
In Germany the telco's big bang wasn't until the mid-1990s but it was followed by huge investments in infrastructure around the county with companies keen to compete with Deutsche Telekom on providing full service (telephone, mobile and internet) to customers. This meant not only leasing capacity from Telekom but also putting cables in the ground to the DSLASM at least and occasionally to the kerb of the house so that only the twisted pair cable in a house is still owned by Telekom. Together with fairly extensive cable coverage, at least in metropolitan areas, this has led to a competitive environment which competes on both service and price. So I've gone from a 2 MB/s a connection ten years ago to 50 MB/s today for roughly the same price. Service quality is important and will drive customers away if it is not maintained and as it will be plastered all over the press.
AFAIK the UK has invested less and competes mainly on price and I wouldn't expect that to improve until the investment climate improves. Several El Reg hacks have suggested that there is no money in providing capacity but that doesn't seem to be the case here.
At the end of the day, however, broadband speeds seem to be a rainbow and I'm not sure if the idea that faster broadband will somehow automatically increase productivity and drive growth. I think for most of us having a connection of say > 256 kB/s would be sufficient for the vast majority of what we do and I've yet to OECD or similar figures painting a different picture. Higher speeds seem simply to favour media consumption which leads to a diversion from, say, CD and VHS rentals to streaming.
Spatial indices on MySQL?
Must have missed it. PostGIS is the way to go if you want to do this sort of thing with open source. I'm getting increasingly sick of comparisons of MySQL (in whichever flavour) with real RDBMS's. The hacks and kludges are just too painful to endure for anything other than toy projects.
By all means get a support contract and pay for DBAs and programmers who know their shit.
PR replaces journalism
Paraphrasing a PR release is not news but I did note that "ACME releases revolutionary new wheel…"
While it is certainly embarrassing for both CloudFlare and Juniper I agree with the article that the best way to handle this kind of SNAFU is to open about it. CDNs are, despite the marketing blurb, a very technical product and with preventing DoS attacks one of their key reasons for existing. You're dealing not only with customers but also other networks and possibly, depending on the size of an attack, with the IETF. While exploits like these that depend on discovering esoteric bugs can be developed silently, fixes need to be public and pushed out across networks as quickly as possible.
Re: Trend and intellectual honesty
Yes, it's simply disingenuous to suggest that Samsung just reacts to customer fashions: OLED screens, CPUs, etc. are all the result of a ten year plan at Samsung. Medical technology is the target of the next ten.
The role of the Communist party and the People's Liberation Army in many of the larger Chinese companies should not be discounted.
As for the "intellectual property giveaway". This is just another strawman to try and shore up the idea of Windows Phone as the pinnacle of innovation. Operating systems were commodified some time ago. Google understands this and the value of selling services just as well as the free-to-play game entrepreneurs throughout Asia.
As for eschewing Western approaches: Huawei in particular has been very busy setting up real R&D labs around Europe. Like Lenvovo, it seems to understand that despite the huge domestic market, really successful companies have to compete globally.
Re: Win8 EULA
If it is as you describe then you don't need to worry as it contravenes EU legislation and can be safely ignored.
Re: EU lost the plot
People reported Microsoft to the courts
No, they reported the matter to the Competition Commissioner. Anti-trust complaints rarely go straight to the courts and I don't even think it's possible for the whole of the EU.
All we learn is that the two sides are equally incompetent.
Please explain how the European Commission has been incompetent.
Anyway ignorance or incompetence have never been valid defences before the law. Sounds like someone is going to have to do some explaining to the shareholders.
