Stolen RAF files are blackmailer's dream

David Hayes

@Think for a moment - AC

"What's the threat? "We'll tell the RAF you're a coke addict."

Not much of a threat if the RAF already know."

Two things:

1) Only certain people in the MoD know exactly what sort of information is stored about you, their boss may not know a single thing about them being a coke addict

2) They could be blackmailed by threatening to turn the information over to the press, not the MoD. Johnny Public obviously LOVES scaulding anyone at the minute, and there have been a few "how can he fly if he's high..." responses from intellectuals on here...

Swedish chopper chief demands fireproof bras

David Hayes


It isn't so much that a fire is a constant threat, but more that if one does happen, you need the clothing to protect your body for long enough that you can either get the fire undercontrol, or you can land the chopper. The final purpose of fire resistant clothing of all types is to minimise any injury to the wearer caused by the clothing itself. A fire in the cockpit is always going to be a painful thing, but if you just get straightforward burns, it's better than burns with melted nylon embedded deep in the skin!

30,000 D-Cell Batteries @ 4 Tonnes

That's assuming that they're proper D-Cell Batteries, and not just AA batteries in a D shell casing like companies like En*cough*gizer have been guilty of. Otherwise, there's a lot of air trapped in the casing providing too much bouyancy, and not enough juice for the size casing it should be providing.

Pentax K-m entry-level digital SLR

David Hayes

Canon 400D user...

Why liveview... occasionally getting a shot from an angle you can't squeeze your head into as well as the camera... but for the most part, to help bridge Compact users across to DSLR's.

Also, the Sony α200 is a very good competitor to to this Pentax, comes cheaper, and has a kit lens that allows for more telephoto than the Pentax (http://camerapricebuster.co.uk/prod609.html)

D-Link demos double-up display for netbooks, laptops

David Hayes

It's a Monitor over USB

90% of the video is talking about how great a second monitor is, and the functionality is all Windows standard, not D-Link. It just felt like he was trying to preach the converted. If he'd sold it as a USB Monitor that is portable, and priced reasonably, he'd get my vote. But trying to tell me that D-Link "created" the functionality of dragging windows from the main display to theirs... please!

Practical uses for Colour ePaper

How many of us have been to a conference, or worse, had to stand at a conference stand. You know the bendy pre-printed screen that sits behind you... suddenly this could be an extremely large presentation display.

Why the IWF was right to ban a Wikipedia page

David Hayes

Stoopid IWF

So they've managed to block anonymous editing to Wikipedia, and prevent you from viewing the Virgin Killers album cover on their website...

So why can I see it on this article then: http://en.wikipedia.org/wiki/IWF_censorship_of_Wikipedia

Thanks Wikipedia for being able to work around the stupid IWF rules!

NASA space tests 'interplanetary internet' protocol

David Hayes

Jumbo Buffers

I agree TCP is not the right medium for interplanetary comms, but I don't agree that it is purely on the basis of the massive buffer required for stable communication, because that is exactly what would be required for the DTP. The only way to ensure that a packet has gone through, is to keep a copy of the packet, and wait until you've had a response from the receiver notifying you they've received that packet. Either in TCP or DTP, that still means holding onto that packet (and the millions of others that you'll be waiting a very VERY long time for).

No mile-high pr0n for Delta passengers

I'm surprised this MiHi WiFi has become news again

I used the Boeing Connect service back in 2006 before it was abandoned. I found it to be slow, but useful in that I could MSN chat to my wife whilst flying over the Atlantic. I tried an MSN VoIP call, but this was broken and unreadable (not enough bandwidth), and there was a noticeable 1000-3000ms packet delay on my pings.

I never did try smut though...

Windows Update to trumpet Vista Capable debacle?

David Hayes
Thumb Up

DirectX comparison not quite sitting right....

Back to the old car then....

My car (Skoda Oct. 1.9 TDi) is according to the manufacturer *capable* of a maximum speed of 119MPH. Well, maybe... but not under it's own power... The best you can get out of it on the flat is 110MPH so I'm told, and you need outside help to get it to 119MPH (downhill, tail wind, slip stream). If speed were a choice for a car, and I bought it based upon the fact the car did 119MPH, I would have been mislead, as it cannot achieve this without external factors.

The same is true of Vista Capable. Standard hardware may be Vista Capable, but to get it to do the things that Microsoft advertised Vista on (and to the layman, never really pointed out that all these bells and whistles were very shiny expensive things only available in the premium versions), you have to rely on more hardware (external factors).

David Hayes


Yes, but you see the problem is, that it can't run all flavours of Vista. It's a bit like buying a spanking new graphics card, and it states it's DirectX compatible...but the hardware only supports DirectX7 calls. Yes it is technically DirectX compatible, but you sure as sh** didn't know about lack of DX8/9/10 support until you parted money.

My Diesel car is capable of both Diesel and Petrol. I say capable, it will technically take Petrol, but it just won't work very well, if at all...

Crashed aircraft is Fossett's, authorities confirm

David Hayes

@Solomon Grundy

"The NTSB says that Mr. Fossetts' plane crashed head on into a mountain - which doesn't sound very much like the actions of a world famous pilot"

But if that mountain and Steve's plane were shrouded in cloud, even the best pilot cannot see through the clouds with the naked eye. And before you respond saying that he should have seen the clouds coming... any mountaineer or any pilot who's flown in mountainous regions (such as myself) can tell you that mountain weather changes VERY quickly. The conditions for "sudden" cloud cover exist daily, even in good weather conditions. Steve could have been forced down below the clouds to try to find a safe passage...

And at the end of the day, even the best pilots make mistakes

M$ are just as good

I've got Outlook 2003 on my home XP Pro PC, but now use Thunderbird as my Default because of it's infinitely better Junk capabilities. I don't uninstall Outlook because I keep it there incase I need to talk my family through setting up outlook on their PC's (always useful to see what you're doing when talking people through).

All is fine until an Automatic Update from M$ comes along, and when next I start my PC, my Email client is defaulted back to Outlook, not Thunderbird.

Tis a small twiddle to switch back, but it's always annoying.

Chrysler grows iPod Peapod

David Hayes

Victory for the Sensible Speed markings

Thanks Reg for using MPH instead of m/h

Also, I would have thought that just because it can't get over 25MPH, doesn't mean to say that it can't be hit by another car head on doing 25MPH, giving a combined impact speed of 50MPH. Having airbags in a collision such as this WOULD be the difference between life and death.

Feck all range, speed, comfort, safety... I'll skip thanks!

Chrysler intros electric trio

David Hayes


Why not mi/h for miles per hour, otherwise, it looks too SI, and that m = metres.

David Hayes


In the US a gallon is ~3.78 litres, whereas in the UK a gallon is ~4.55 litres. 50 MPG (US) ~= 60 MPG (UK). 60MPG for a petrol is a good figure, especially a 4x4!

It's not a huge leap towards 100MPG (UK), but it's all moving in the right direction.

"can also switch between 12 and 24 hour modes of time display."

How exactly can it display it though. The LCD looks like it can only display the number 1 as the first digit. There doesn't appear to be any space for the elements required for the number 2!

Maybe I'm missing the ball here, but according to http://www.infoworld.com/archives/emailPrint.jsp?R=printThis&A=/article/08/08/22/Mozilla-boosts-JavaScript-performance_1.html, the 3.1 trunk was supposed to include native code compilation for JS. Running 3.1 alpha is just as slow on SunSpider tests as 3.0.

Straw poll, how many non-developers know or more importantly care to install a different browser to IE.... I'd argue not that many. How many non-developers are going to visit w3schools.... I'd argue not that many...

"Anyway, our data, collected from W3Schools' log-files, over a five year period, clearly shows the long and medium-term trends"

Go to a football match at Wembley, between say ManU and Chelsea, and carry out a straw poll of people outside the grounds who their favourite team is. 45% ManU, 45% Chelsea, 10% other. Now ask the whole country, and get a much more different, and more RELEVANT statistic...

Statistics are dangerous, because people use them to misrepresent facts.

Ice in fuel caused Heathrow 777 crash

David Hayes

@Brian Morrison

I'm duly corrected!

David Hayes

@ I. Aproveofitspendingonspecificprojects

Um...., no "broken wings", the Undercarriage sheared off on impact, but the wings themselves are "intact". Structurally, 2.3G's instant loading on a 777 wings is not a major deal (strong turbulence is likely to reach that level of load). The three tanks will likely have remained in tact, but as the report states (RTFR), the Fire and Rescues efforts to reduce the chances of fire, contaminated at least the central tank.

The report also states (RTFR) that the aircraft was Sumped on the 14th of January when it was in for maintainence, and was routinely sumped on the 15h prior to it's outbound flight to Beijing.

And I mentioned filters...

David Hayes

Single-Prop Pilot, not a Scientist...

...but to me, reading the report, it seems that the low volume of fuel in the centre tank remained there for the majority of the aircraft's flight, and especially existed when the aircraft ventured through the coldest portion of the flight. All the air in the central tank would act as a wonderful insulator to the warmth of the cabin above, but being quite close to the skin of the aircraft, would have been especially cold (gravity pulling the fuel to the bottom of the plane and all).

Then they scrubbed the centre tank contents into the respective left and right-hand main tanks, pumping whatever ice-crystals had formed in the fuel with them. Being uniformly spread in the centre tank, the main tanks are now uniformly contaminated.

A descent from FL400 doesn't require a significant level of thrust, and so the fuel flow would not have been excessive enough to disrupt the suspended crystals. However, the approach to LHR requires the constant changing of the thrust (at times to high levels), which would have started to clog up the filters. And if you've seen what happens to your plug-hole when you get hair clogged up, you'll appreciate that ice clogging filters will only cause more ice to stick to it as it passes. In fact, an increased demand for fuel will actually causes more ice crystals to pass near the filters. Some of these will naturally join with those already on the filter. In a twist of irony, demanding more fuel may actually speed the problem rather than solve it.

Why did the engines fail around the same time, because both tanks would have been uniformly contaminated by the central tank, and layman math would suggest 7 seconds difference between failures would be perfectly reasonable.

But that's just my 2 inches of manifold pressure!

VPN security - if you want it, come and get it

David Hayes

Wow, how complex

I remember using Hamachi (now LogMeIn Hamachi), and this was MUCH easier to set up a VPN. None of this DynDNS BS, Install the software, create a name for your network, create a name for your PC, install the software on the end machine, create a name for your PC, then join the network you created by name. Then I install whatever services on my server PC that I want, such as AnalogX Proxy: http://www.analogx.com/CONTENTS/download/network/proxy.htm

Now it might not be Open Source, but it is Free, and before it was bought by LMI, it went through a huge development effort to make it very secure, useable and great!

More boffinry

Re Travelators:

It is the forward inertia of the aircraft that you need to arrest. Sticking the aircraft on a travelator will not slow the inertia of the aircraft, but the wheels will simply spin underneath the aircraft. If you were to apply the brakes you would gain no improvement on reducing inertia on a moving platform than you would for a stationary one (brakes only reduce inertia by a set amount, and that is not dictated by the velocity of the wheel).

For the less boffin inclined:

Watch the episode of Mythbusters where they drive a car at 40mph (I think) on to the back of a trailer, and watch how the car doesn't magically lunge forward when it hits the relatively stationary ramp. This is the same principal. If the car was driving at 100mph, and mounted the trailer doing 40mph, it still needs the same amount of space to slow down frm 100-40mph, as it would 60-0mph.

For the idiotic:

Find yourself a treadmill, a good run up, and a bike. Set the treadmill to 10mph, and ride as fast as you can towards the treadmill (should get a decent 20mph). Launch onto the treadmill, and try and stop in the short distance... See you in hospital!
