Ill communication delays NHS England's GP data grab for six months

James Turner

Re: Why does anything identifiable need to leave the GP?

Because they're matching it against the hospital records they already have. So you can do things like spot everyone prescribed a certain treatment later turned up in hospital suffering a particular illness.

The identifiers are then kept separately and the data released only has the things you mention.

Wi-Fi Alliance takes grid place, revs engine in race to 802.11ac

James Turner

Re: Can someone explain...

Because we got to z and have wrapped round.

There is more than just your main wireless types, standardising QoS (which can apply to any of the types) is 11e, 11i is more commonly known as WPA2...

Are the PCs all getting a bit old at your office? You're not alone

James Turner

Reason to upgrade...

Power consumption anyone?

I upgraded from a Athlon64 X2 4200 last year to a Core i5 3550. The old system used to idle at 100W (measured at the wall). The new one is less than 50W.

Newer machines won't be quite that dramatic a difference, but there are still some savings that can be made by replacing older desktops.

BT copper-cable choppers cop 16 months in the cooler

James Turner

Re: Simple solution

Except the thieves are too stupid to tell fibre and copper apart. I've seen several cases of BT fibre infrastructure being ripped out by thieves who thought it was copper.

Intel debuts 'Haswell' chippery: from tablets to servers

James Turner

Re: Not to throw a damper on this lovefest...

Do you have a source you can cite for that? All the articles I've seen state Haswell supports OpenGL 3.2 and OpenCL 1.2.

AMD puts network, chip guru in charge of Opterons

James Turner

Re: take a leaf from ARM

Isn't the process migration something the OS should be doing? AMD and Intel already shut down many bits of their CPUs (including whole cores) when they're not in use.

AMD are already doing that with their latest generation graphics cards, they're calling it 'ZeroCore'.

The problem with lots of small servers is the overhead. Even your dinky little ARM servers are going to be using some power all the time. Whereas in a virtual environment you'll have fewer servers so the base load of them sitting idle will be less. You can even shut down servers completely if the load isn't sufficient for them all to be running.

OCZ RevoDrive 3 X2 240GB PCI-E SSD

James Turner

Really the end of sata?

I'd say these PCIe flash cards merely reaffirm sata/sas, as they all seem to be made up of sata drives and a raid controller, it's just instead of a sata cable, it's a trace on the pcb.

HP frogmarches new Xeon, Opteron chips into ProLiants

James Turner

Re: New?

That was presumably the E5-2600 version of the DL360 Gen8 (which appear to have gained a p suffix), whereas these are DL360e Gen8 (note the different suffix).

Nice way to confuse people HP. At least Dell are giving their systems different numbers (their equivalents are R420 (E5-2400) and R620 (E5-2600).

Intel goes wide and deep with Xeon E5 assault

James Turner

Re: Intel thoroughly missing the point here

I don't think Intel are missing the point, they just see gaps in their line-up that need filling. (i.e. between single socket and a full-on dual socket, and between dual socket and their big E7 quad setup).

Intel cores are currently faster, clock for clock. For example, lets take anandtech's review of the E5-2600 ( http://www.anandtech.com/show/5553/the-xeon-e52600-dual-sandybridge-for-servers/ ). In that they take a simulated E5-2630 (6 cores, 2.3GHz) and they reckon it beats an Opteron 6276. Thats a $616 CPU beating a $788 CPU (list prices for both).

But still, the Opteron reaches futher down than the 2600 series does, so Intel knocked off a few of the extras to produce the 2400 series to compete with those. Likewise, the E7 is overkill for many where you just want 4 sockets-worth of ram and cpu, so bump up the E5 to fit there.

Browsium rescues HMRC from IE6 – and multimillion-pound bill

James Turner

Really a fix?

I may be wrong, but I was under the impression that these things are essentially still using IE6, but hiding it round the back. What happens when XP support goes? You're still stuck using components that MS aren't supporting, so you'll be stuffed in just the same way as soon as a bug comes up.

Cisco Nexus ports stretched to take 40GE and 100GE loads

James Turner

Indeed. They've typoed the name (It's a 6904 card, not a 6094). And the 44 ports is for a full 6913 chassis. It's 4 ports per card.

Chrome browser 'is becoming Number Two'

James Turner

Why would you assume that?

People have to go out and actively get Opera mini for their smartphones. Whereas the huge number of people waving iPhones about will all be using Safari by default.

Apple finally purges Mac OS of disgraced DigiNotar certs

James Turner

There's a paper http://www.thoughtcrime.org/papers/ocsp-attack.pdf on how the protocol can be MITM attacked.

Rather than bandwidth usage, resource usage of the server running the OCSP service might be an issue if you get millions of requests. If it takes a while to respond, people will complain their browsing is slow (you're waiting for OCSP to respond before trusting the site). If it fails to respond at all, do you block access to the site? (That'll be disabled if people want to get to their stuff). Or allow access, risking people going to a site that shouldn't be trusted?

VMware taxes your virtual memory

James Turner

Re: Gun to the head

Are you actually maxing out the ram on all your hosts? As long as your VMs are collectively using less than 32GB x number of CPU sockets, your licences are good. If you're just over, you might be better buying a few additional Enterprise to get additional licences than upgrading to Enterprise Plus

AMD gets in Intel's grille with desktop Fusion rollout

James Turner

Sandy Bridge gaming

The problem for AMD, is the pricing of the new kit appears to be higher than for a basic Core i3. With the difference, you can buy yourself a nice discrete card as good as the integrated unit in AMD's APU.

So, a faster processor and similar graphics for the same money. Only if you absolutely have to have it integrated does AMD look a winner.

Intel charges premium for Xeon E7 scalability

James Turner

Re: AMD has them beat for Virtual Machines

Is that still the case? I know HT used to be a bit of a dog, but the current versions are much better.

VMware's vSphere best practices guide states "For the best performance we recommend that you enable hyper-threading".

Anandtech have some benchmarks from when Opteron 6100 and the Xeon 7500 were new and the Xeon was faster ( http://www.anandtech.com/show/3894/server-clash-dellr815/10 ).

If the E7 is faster still...

Seagate takes a terabyte of the storage apple

Re:Hm?

The Western Digital drive is presumably a Scorpio Blue, which is a 5400rpm drive. The article is talking about this being the first 7200rpm 2.5" 1TB drive.

Broadband boss: 'The end of freeloading is nigh'

James Turner

Sustainable pricing

The suggestion of the article is that most of these providers are only 'happy' for you to download that much because most of their customers don't.

If everyone was maxing out their connections they might have to charge something closer to what BT Wholesale want.

Intel wants vintage x64 servers on rubbish heap

James Turner

Re: Imitation is the most sincere form of flattery

If you put it into the server chips, you start to make it more attractive to do your load balancing with nice cheap servers, rather than buying expensive black boxes from the aforementioned vendors.

If you want it on the desktop, buy a Core i5 (or a i7-980X).

Via may have had acceleration for a while, but Intel chips were probably still faster even without.

Re: why?

The 8-core chips from Intel aren't entirely comparable. (aka Beckton, Nehalem-EX or Xeon 7500)

They're more akin to being a pair of 5500s in a single package. So they don't have all the architectural advantages of the 5600s.The other main difference is they use different sockets. 5600s go into boards that only take 2 processors, Beckton will go into 4-way and above.

Intel's redemos six-core Gulftown

James Turner
Jobs Halo

Mac Pros

Mac Pros use dual-socket Xeon 5500s, rather than the single-socket Core i7 line.

So the upgrade would be likely to be the dual-socket Xeon 56xx range rather than a i7-980X. Going from a pair of quad-cores to a single hex-core would normally be considered a downgrade.

Internet Explorer 8 still not mingling well with 2,000 highly-visited sites

James Turner

Not quite.

This story is about sites that have been coded with all the crappy hacks needed for IE6, but are just feeding IE8 that version rather than a properly standards compliant page that IE8 can handle. IE8 then has to be told to pretend to be IE6 to render 'properly'.

Government defeats Tories in 'McKinnon' extradition vote

James Turner

@AC 11:18

I don't disagree the treaty is a load of cobblers.

But making factual errors weakens any argument. As the article now says the treaty is one-sided is rather different from the original version saying the US haven't been bothered to ratify the thing.

That was why there was Fail.

McKinnon launches second extradition challenge

James Turner

@AC 16:05

But if you visit the US then you're bound by their laws. Generally you're under the law of the county where your actions happen. The tricky bit with computers is defining where the action is. The servers are in the US, so it's not unreasonable to consider whether the crime was committed in that country.
