Vatican vetos 'dot god' domain

VMware renders multitasking OSes redundant

Chris Ellis

Well whats the point

If the VM is doing part of the work of the OS then why use Virtualisation. Instead move the features of a VM that people like into the OS.

The ability to live migrate an OS to other hardware would be very neat.

Facebook summarily denies undeniable user-menacing security hole

Chris Ellis
Thumb Down

What do you expect.

Its written in PHP and MySQL, hardly known for secure applications or scalability. Its a power keg waiting for crap developers.

IBM solves world's 'paper or plastic' crisis

Chris Ellis

Only one problem

You would loose 73 seconds per transaction waiting for the IBM button to call down via 320 different IBM frameworks before an action is actually taken.

BT slams bandwidth brakes on all subscribers

@ david bates

We ahd a similar issue with eclipse, and we weren't torrenting much just a lot of RDP. Our connection used to get about 25kB max yet we could sync at 7mb. After moaning a eclipse for months and upgrading to option 4, they simply said

"that is the performance we expect for your package"

What can you say to that.

Man powers up PC to pop popcorn

Chris Ellis

By my calculations.

If we assume that we want to heat 10g of popcorn to 150C , then by my calculations:

Using Specific Heat Capacity:

q = mct

c = 4200, t = 130, m = 0.01


q = 4200 * 130 * 0.01 = 5460 J

Now Power is Joules per Second:

p = q / t

p = 2.5 , q = 5460

Therefore in order to raise the temperature of 10g of pop corn to 150C at maximum USB power it would take:

5460 / 2.5 = t = 2,184 Seconds = 36 Minutes

This assumes that heat transfer is 100% efficient and there is no heat loss.

Now providing that the heat input into the system is greater than the heat loss, there should eventually

be some popcorn.

I think the more interesting question is how long it took.

Another thing to note, is that the USB bus does not provide 500mA of power unless requested by the device.

Therefore it is likely in this situation the USB bus is only providing 100mA, IE 0.5W

But that is just my views.

Bavaria sanctions police spyware

Chris Ellis


How long before a security patch is released to close the holes used to install its self, Or are the police going to force terror suspects to install it.

After all what stops a malicious attacker using the the same exploits, or even better exploiting the spyware.

I doubt it has a Linux variant, and if did I'm sure the security hole would be closed immediately. Therefore if your a terrorist, use Linux.

Intel Atom 230 ultra low-power desktop CPU

Chris Ellis

VIA Nano

I'd really like to see this chip compared with the new VIA Nano processor, 60W of power is seriously high for these kind of systems.

From what I've seen in the tests it looks like the VIA Nano could very easily beat this processor on performance, which would be interesting.

The VIA Nano is already beating the 1.6GHz Intel M parts on performance per watt.

Windows Server 2008 cuts power costs, claims Microsoft

Chris Ellis

Doggy Research Alert (after all it is by Microsoft)

Having spent the last year doing research into server power efficiency I am both interested and skeptical.

Although this saving 10% is pitiful, the system I designed was using less than 30% of a dual core dual CPU Opteron server. 77W instead of 226W, reading to a significant saving on operational costs.

A 10% power saving would equate to around 30W upon an average server. The question is how is this achieved, most server processors do not really see this power saving. Secondly is this an averaged power rating or instantaneous. For example, if the OS is using less processor time when idle then over 24hr this may be possible, however if the processor is under a constant full load, the power consumption of both OS should be within 1% or so, since the CPU consumes around 80% of a servers power. If the power saving is instantaneous then facts about the situations are needed.

Certainly power management features of OS can reduce power consumption, so it would be very interested to see Linux Vs 2008 server. I expect Linux will beat server 2008 hands down.

This comment in the article I find highly amusing:

"Hyper-V can still throttle the amount of voltage to the CPU based on load – which is something VMware and Xen can NOT do today,"

This amuses me for two reasons, firstly altering the core voltage of a CPU is highly likely to cause it to crash or worse. Secondly there is no standard system to manipulate the CPU core voltage on most server motherboards as it requires direct control of the Core Voltage VRMs.

Is there anywhere I can get a copy of this paper, I'm quite interested to see the latest propaganda of Microsort.

National Grid computers locked-down in outage cock-up

Crypto Cookies

Instead of random numbers why not use cryptographic cookies, exactly like in Qmail's mailing list manager and the SYNCookies Linux kernel path (Both by DJB)

Good News

Always been a fan of AMD and VIA processors.

Is it the British liking of the underdog?

Battery Life

Considering that the VIA PICO-ITX (Same processor and chipset) consumes 10W of power under full load, I bet the battery life is excellent.

I really want one of these, However SUSE will need to be replaced by Mandriva.

All the problems with email arise due to its acient design.

Trying to have a system backward compatable would just render the new system useless

The sooner we ditch the current system the better!

Facebook loses a few bitches

IT Angle


I had resisted joining facebook until last night, mainly on privacy grounds. I must admit that after using it for about 2 hours, it is painful to say the least.

The website is poorly designed a slugish at the best of times. It is difficult to use, certainly to find people. However best of all, trying to hide ur personal info, is so complicated and irritating. I found the best solution was not to add any info.

UK gov sets rules for hacker tool ban

Chris Ellis

Free ?

I used to think that this country was free and stood for ideals. However I am sadly mistaken over this illusion. What I'd like to see is this country run by democracy and not the current dictatorship which is Labour.

Zend crafts application server PHP implant

Why would any SANE Java programmer want to pollute their wonderfully designed app with god dam PHP,


Somehow I think Zend are barking up the wrong tree, maybe even forest.

Mandriva Linux 2008 is out and about

Chris Ellis

Mandriva Vs Ubuntu

I've been a long time Mandriva user so I am completely biased however. The Mandriva configuration tools and the entire distro feels more rounded compared with Ubuntu, however this is my PERSONAL PREFERENCE.

Rather than the OS community continually bitching about different distros, Why not admit they all have differences and in the end are fairly similar, get over it, find that YOU like and get on with it.

Mozilla confirms own URL handling bug

Chris Ellis

Both at fault

Both MSIE and FF are at fault!

Any program should validate its input data before it does anything else with it, thus MSIE should validate the data pass it to FF which validates it again. It is a common failure with ALL programs that they never validat input data.

Browsers are not the only insecure programs, infact it is hard to think of many programs which are. It is a generalised failure within the software industry which breads bad programmers and software. Focus is always on cost and not quality.

Home Office discusses thief-proof phones

Chris Ellis

Possible but no point.

Shutting down a phone once it hase been stolen is possible. Using appropiate techniques it is possible to make it impossible to reprogram a microprocessor. Also there is no reason why a shutdown comamnd could not permantly dissable the phone, that should be relatively mundane.

However the only problem: is there a need for a solution ?
