Re: A hex upon thee
However they don't handle the central pin added for "security".
Equally there is no patch for XP/Vista to make it possible to disable RC4. Or support for TLS 1.2.
Old versions in extended support don't get new features.
> As a web browser user how do I tell if a site is using RC4?
In IE: Right click and select properties: details of the ciphers used is under connection.
In Chrome: click on the padlock on the address bar and click on the connection tab.
In Firefox it is in Tools | Page Info at the bottom of the General tab with more details on the Security tab.
Re: Rose tinted spectacles
> The Googled tutorials on W3C all agree that the method is supposed to give focus to the target window.
Then they are simplifications and/or out of date.
I suggest a reading of the specification of Window.focus() (and Window.blur()), especially the Note at the HTML5 specification. Direct link for the latest working draft: http://www.w3.org/html/wg/drafts/html/CR/editing.html#dom-window-focus.

Assuming you mean VB6 then no, or at least not any time soon.
Win8 and 8.1 include the VB6 runtime, so that is supported—you applications will keep running—until at least those OS' go end of life (for Win8 enterprise currently set at 2023-10-01).
Of course if I business is still, in a decades time, running applications written what will be a more than 25 year old tool, then perhaps that business is itself so obsolete that it is time to switch off life support.

> Doesn't StackExchange work primarily on OpenID - I have about a dizen sites all on the same login so that's going to be annoying.
1. StackExchange has its own openID provider: set up an identity there as the future replacement.
2. StackExchange has a central identify across all its sites, so you only need to change once. You might need to log into each site (that isn't a sub-domain of stackexchange.com) separately with the change.
3. You can have multiple logins configured for your StackExchange account. Therefore adding the new identity while still being able to login with the current one.
Doing this, and updating by domain's default page's link elements away from myOpenId, is now on my to do list...
OpenID is in so many ways the right approach to identify. However the failure of the various OpenID providers (especially Google in the early days) to provide a consistent approach for the consumers of OpenID logins (the web sites you login to) made it too unreliable and too hard in practice.
> It's not wrong at all. Just depends on your preference, as long as it's all consistent.
Exactly. If you cannot read and maintain any consistent style then you need to think of a different career. There are far harder things in programming (understanding what the customer wants for a start).
OTOH one can have a preference: one true brace style is called "true" for a reason :-).
A coding style only needs four unbreakable rules:
1. Be consistent.
2. Indent to make program structure clear.
3. Name's clarity (eg. long and more more descriptive) should reflect their scope.
4. Tabs/spaces [choose one for the team/organisation, delete the other] only.
/Everything/ else is subject to argument and exceptions.
Re: If you liked this....
Certainly worth a visit. They have a collection of cold war military equipment including a WE.177 case (well I hope it's empty).
Lots of signs to it in the area... really must get a photo of a few on a visit to family in the area at some point.
In the early days of Azure there was a lot of talk about lots of security verifications being done (usual alpha-numeric soup of standard identifiers).
So it is possible PCI-DSS is covered.
But likely you'll need to ask Microsoft directly if a hunt for "Azure security compliance" fails to show anything.
Re: Super Proton Synchrotron
> Radiation damaged cables? How?
Read up on synchrotron radiation: when you use an electro-magnetic field to change the direction of charge particles (eg. protons) EM radiation is emitted. At the energy levels of CERN this is hard X-Rays.

> BBC has to constantly transmit every local station as a full stream
If I recall correctly this has already changed or is due to sometime soon if not done already.
The problem was combining the variable bandwidth stations in the MUX with the regional BBC1 feeds and sending to the regional transmitters: the technology to make BBC1 variable width in each region and merge didn't exist when Freeview started.
With newer kit, HD and analogue switch off the situation has (or will soon) change.
 I seem to recall it was linked to the completion of analogue switch off and HD roll out.
"NATO Standard Rounds" makes for simpler logistics, and in the end conventional wars are more about logistics than anything else.
Re: "The temperature scale simply does not end at infinity,"
> Or do they have other research going on that gets to negative values of temperature by heating something to infinity and beyond?
That's exactly it.
The Wikipedia article http://en.wikipedia.org/wiki/Negative_temperature has been cited as containing a good introduction.
It is an effect in a quantum system so you need to forget your intuition.
> Isn't 486 a 386+maths coprocessor?
Not necessarily: remember the 486SX?
Plus it made some significant changes to the instruction set that made multi-threading significantly easier. For example the atomic interlocked increment and decrement operations return the new value rather than just a zero or not-zero indication. Hence (from the article:
> which complexity has plagued us with extra work whenever we wanted to change SMP primitives
(And also why the InterlockedIncrement and InterlockedDecrement Win32APIs where different on WinNT vs. Win9x.)
I Think Wear Leveling Will Still be Needed
> look like making wear levelling irrelevant.
I don't think so.
Image a block being written once a second (quite possibly pessimistic for something like control information in a database file on a busy server), that's ~31.6 writes a year.
So 100 million is reached in a little over three years.
So unless the ">" in "to > 100M Cycles" is really order of magnitude greater than, wear levelling is still going to be needed for server (ie. enterprise grade) SSDs.
Re: I'm no physicist, but ...
Vacuum is not empty.
All that quantum fluctuation (where the closer you look the more noisy it becomes) for a start.
Plus the odd bit of dust or gas.
(The vacuum used in The LHC contains considerably less matter than in inter-planetary space.)
> A Dyson should be able to suck up a real one. Or a lamb. Or at least kittens.
Which leads to the question: what is the speed of a kitten in a Dyson?
Should be a little more of an everyday speed that a sheep in a vacuum? (The outer space kind rather than cleaner kind of course.)
Re: The good old days...
> 0.066666 FLOPS
To put this in perspective, the Harwell Dekatron described was built in 1949, so assuming it was running continuously ever since it has 63 years of runtime at that 1/15 flop/s.
And then compare with the 27PFlop/s Titan at Oak Ridge (top of the latest Top 500 list).
A few calculations...
Titan would take about 500nS to perform the same number of operations at the Dekatron in 63 years.
Five hundred NANOseconds.
Even a nVidia Tesla card, running at about 1TFlop/s would only need around 130μS.
Even a computer as slow (by today's standards) as a megaflop would only need a couple of minutes.
Re: I just spat out my instant noodle
Remote code includes documents received from other parties.
For lots of "near" misses...
I would expect Peer1 (who run the DC) will be looking at that in the future.
The fuel tank may well be stuck in the basement by local planning (zoning) regulations, but maybe putting the pumps in the ground or first floor (1st or 2nd for USAians), maybe with a submergeable booster next to the tank (to get things moving).
Re: Use the cloud
Some web sites have done that.
StackExchange.com (including StackOverflow.com) are running out of their backup DC in Oregon, some of Fog Creek's applications are now in AWS.
Of course this isn't something you can just magically do, throw some servers into another DC and it will work, you need both application changes and administrative processes (and monitoring) that will allow the fail over. (Eg. StackExchange recently – in a rather timely manner – tested their fail over, found some issues and fixed them.) Whether for a given web site it is worth the costs for the level of risks is a business choice.
Re: Anyone actually expect the hardware is the same?
> You'd hope performance would be equivalent regardless of the hardware.
Not really, I would expect performance to be no worse (and often better) than the minimum specified for the type of VM.
Ie. you get at least what you pay for, but you might get lucky.
Of course those faster, more modern, host machines could be getting a higher density of VMs loaded on to them. So a faster CPU might just mean more users sharing it so – on average – you end up getting the same availability of CPU instructions executed per unit time per VM.
Arguably for much of physics even the SI units are a RPITA. So many things would be easier with "natural" units. For example in particle physics using Planck Units, however these are not exactly practical outside their specialisms (time in units of approximately 5.4e-44s and distance of 1.6e-35m).

Re: Problem for 3-D Secure?
This is not a security hole: if you can access this you already have complete access
To access this information you need to either capable of taking ownership of that part of the registry or running as SYSTEM.
In either case you all ready have complete and total control of the machine.
(The linked article acknowledges this., Hint: check out the ACL on HKEY_LOCAL_MACHINE\SAM\SAM.)
Another case of if you are already inside the safe, the you have access to the contents of the safe.

Re: Actual server figures
Based on http://www.zdnet.com/boston-viridis-192-core-server-consumes-only-300-watts-of-datacenter-power-7000001654/ it appears that 300W does /not/ include the HDDs.
Clearly using SSDs will add the least power (but the most cost), while high performance spinning rust will use more. Looking at the spec of Seagate's Savvio 15k 2.5" disks: operating power is almost 8W.
So with 24 of them that's almost another 200W.
Still low compared to x86, but getting a long way from the 300W headline.
Be very careful when looking at manufacturer's specifications in the area they are claiming leadership: their information is spinning more than the HDDs they're not including.
