Bought a no-moving-parts power supply back in... oh, I don't know, 2003 or something. Sold as "cooled by heatpipes", pretty much the same principle - silent, no moving parts, passively cooled, no fans, huge surface areas.

They also did kits for the processor itself but I've also bought P2-era motherboards that were designed to be passively cooled too (same thing, huge heatsink, no fan).

So this is certainly not "the first" in the PC world (unless we're talking about "the first" to use some particular technology that just about replicates what I bought over 10 years ago). Not even close. In fact, it's over a decade out. And going outside the PC world, passively cooled chips are pretty common - you have a tablet or smartphone without a huge stonking fan, no?

The PSU is still working 10 years on if you'd like me to dig it out. I'm sure it wouldn't take much to butcher it to do the same job to the processor, especially if you can safely have it clock itself down to prevent heat being generated in the first place.

Agreed, in principle, but we're still allowed opinions based on experience.

When I've worked in primary and secondary education, state and private, deprived areas and the exact opposite, it's hard to see where the advantage is at all. The above is not a post from ignorance, it's a post from someone deep inside IT inside education, who has had phone calls in my professional position from parents of deprived children begging for technical support (and they got a lot more than they hoped for, and it didn't cost them a bean).

I'm not claiming to know everything, but what I've seen shows an inherent flaw in the "let's give kids computers" charities - they are starting from entirely the wrong premise - that access to even the cheapest of hardware is why the children are having problems. It's not.

I work in schools.

I work in IT in schools.

I've only ever worked in IT in schools (or colleges, or tuition centres...).

School computers do not make better students. Home computers do not make better students. Personal computers do not make better students.

If anything, the opposite unless they are regulated... by a teacher... in a classroom... and they have the will to learn. Guess which are the magic factors and which aren't?

Sure, there are disadvantaged children that don't have an Internet connection, a PC, time on it, and can't fill in their homework that the school provides on its website. The number of them is VANISHINGLY small. And, usually, because of much bigger problems that have nothing to do with technology - i.e. the kinds of families that you would find had sold the PC the next week for money to buy something else. They are dozens of charities, government schemes and even schools that do this. It's not taken up en-masse unless you are giving SILLY amounts of money to it, and then it's taken up to save them paying a bill that you could have just paid for them twice over.

And then, when I was a kid 15-20 years ago, I didn't have much access to a PC either. I came out near the top of my school. In IT. It wasn't a burden. In fact, my teachers fretted about my wasting so much time on the computers when they did come in.

Let's get this straight - giving an old recycled PC that someone was throwing out to a kid does not give them anything. I can't give this stuff away, when I throw out dozens of desktops a year, for a reason: you can run old stuff on it, if you're careful. So instead of "no PC", they have "slow PC full of junk that either can't run or is ancient". They're better off with no PC. Sticking it onto the Internet is, again, just a recipe for disaster. Now all that rich online content, tied into the school's cloud systems, requiring all kinds of plugins... they still can't view as intended.

Sticking them on Linux isn't going to help either. I speak as someone who HAS deployed Linux machines in schools, is never without a Linux server somewhere, and has Linux at home. And Windows. And (spit) Macs. And I was an early backer of the Raspberry Pi project. All it means is they won't be able to read their homework in a format that the teacher can send or send their homework in a format that the teacher can read. I *know* that you and *I* can do that, but this are disadvantaged kids with no PC skills stuck on an unfamiliar system that few people can help them with.

STOP GIVING THIS CRAP TO CHILDREN in the first world. Nothing is actually *better* - they then might have to come into school and do stuff like learn. And if the kid is that disadvantaged but able to learn, there are libraries, after-school clubs, lunchtime clubs, or they can negotiate after-hours access with their schools direct - which might just help those parents struggling to leave work in order to pick them up...

Sending this stuff to the third world doesn't help either. They have the same problems, and have to deal with too much junk.

On top of all that, unless you're online it's pointless. The Linux educational software is NOT educational software. It's some geek's idea of educational, conforms to no curriculum whatsoever and, if you're lucky, can be crowbarred to fulfill two or three curriculum requirements over the course of a year. And if you have to put these kids online to do what they need, THAT is the cost and the expense and the problem, not what device they happen to access it from (by the time you are then, any kind of thin-client would work, backed by their school).

Really, we need to find other ways to solve this problem, not just throw old computers at kids. It's not even as useful as throwing old library books at kids.

Sorry. I don't "subscribe". The value of it rarely lasts long enough to be of any value at all to me.

Magazines? They tend to repeat themselves after a year, then you realise that all the "new" stuff, you now know where to find out. (Did this for PC magazines, Linux magazines, Astronomy magazines, even New Scientist is ludicrously expensive for what it is).

Movies? You get all of the crap, nothing that you actually want. I did the test subscription to Amazon Prime Instant Video. 30 days of "free" movies. We watched 4. Stopped one within ten minutes. Spent HOURS looking through what they had. All the interesting ones were "not included" so you had to buy them anyway. The subscription didn't make it out of the trial period. Was the same back when video rental was the thing - the good movie that you'd been waiting for was unavailable or more expensive, all you could book out was the dross you'd seen a hundred times.

Games? I have Steam. But I don't have a single subscription game. There are even Steam games that I regularly plug money into for DLC and extras, and I have my own personal "monthly Steam allowance". To be honest, not one of the subscription games (or software) have I even looked at past the word "subscription". Nope, never played WoW either. Sorry, but I invest enough back into games I play (by running servers, helping out on the forums, bug-fixing, or buying DLC / extra copies for friends), I'm not paying every month "just because".

I tried OnLive, mostly to prove that it wasn't a sustainable business model to be honest. I played a full-price game on there for free, then went and bought it cheaper elsewhere. The technology worked but was nowhere near the claims they made. And the "lifetime" (3 years only) pass to the game cost more than my buying it outright on Steam.

I don't see any subscription as worthwhile. Once they have your first month of money, they can destroy the value of what you have overnight and you'll feel obliged to keep paying until renewal. It's just not worth it.

If you want to subscribe to EA games, stick some money in a tin every month. Then when EA only have the same crap as usual, you can go elsewhere, and when you have a month without playing, you're under no obligation, still have your money and can play twice as much next month.

So what's new?

If you don't need credit, they'll give it to you. If you do, they won't. It's the general rule of banking.

How else can you explain that NO credit history is seen as worse than a mediocre one? For years, banks ignored me precisely because I'd never taken out a loan, credit card, etc. It was only once I'd got one that they desperately tried to push more loans down my throat. Up until then, apparently, I'd been too much of an unknown to risk it.

Credit scoring, the entire premise, is flawed. It's based on the reputation of your previous credit, and bears little resemblance to reality - as you point out. And try taking out a credit card and then RELIGIOUSLY paying back the full amount every month for many years. They hate you for it. Your credit score is still basically zero.

Credit score is not a reputation or history-based score. It's purely arbitrary. There's even "traps" like "use this high-interest credit card that we will give to people with no credit history just so you can 'improve' your score". WTF?

Hence why, as much as humanly possible, I don't use credit. Pretty much, for the last five years, I have no credit "history" as such (no credit cards, no loans, no judgements etc.), earn twice what I used to, and have never had anything "bad" on my history.

Was still refused for a joint mortgage with my girlfriend, though. Weird, because I'd had a mortgage previously for 3/4's of the same amount, earning half as much, self-employed, never missed a payment, sold the house for profit and paid off the full loan + interest early.

Ironically, my girlfriend (who's Italian, hadn't worked in the UK, had never owned a house, was refused a credit card for lack of history, and earns less than me) was approved for the entire mortgage on her own, so I just pay her half the mortgage and she's the one on their records. Oh, they offered to "put me on the paperwork" in a couple of years. This is despite the fact that in the UK, credit records (apart from bankruptcies and county-court judgements) are supposed to expire after 4 years.

Hell, they will CHARGE YOU to view your credit history, and in the UK you have to get your history from several large credit-history suppliers in order to make sure you have the full picture - some banks use one supplier, some use another, and their information can differ even though they are supposed to share it.

It's a scam. It's got nothing to do with risk, it's everything to do with maximum profit - and that means that you get a better "score" if you get into debt but don't quite go bankrupt.

1) You've confused American "schools" with British schools, where the pupils are children. I specifically mention primary and secondary - primary is up to age 10/11.

2) We still have tracing of what was accessed, it's still against school rules to allow someone access to your account. Their actions aren't your responsibility but may have been your fault.

3) Any "school" that expels a kid for losing their key and another kid doing stuff on their account, won't be a school over here for long.

4) No school will charge for a crime in such circumstances, unless a crime was committed, and then you have the "reasonable doubt" defence and legal requirements of proof.

If you think for a second that a teenager losing their access card is any different to them leaving the machine logged on for the microsecond it takes one of their "mates" to reach over and do something on their account, you're an idiot.

I'd like something like this for a mixed Windows/Mac/Linux network but the costs are just prohibitive.

Yubikeys are $25 each for the hardware, and $45 PER USER. That's just ridiculous when you scale up, and there's an awful lot of manually faffing about to get to the point that it works.

To be honest, in my scenario (primary/secondary schools), I'm not looking for 2-factor as much as "I don't have to remember my password" login. If someone has the key, they have access (but only to another pupils account, which is nothing), and leave 2-factor as only a consideration for the staff (so then you could buy Yubi just for the staff, etc.). But anything software-licensed per-user is just ludicrously expensive when you start adding it up, on top of the "per-user" device costs to start with.

To be honest, I'd pay £10 each for a set of USB tokens that - when you press the button - just types in a username/password for you. Yubikey doesn't solve that problem on Windows, it just makes existing logins much more complicated (and, as pointed out in their manuals, when you get into mobile access they are useless anyway).

If someone could come up with a £10 USB keyboard-emulating device that types in a given string (I can code it so it presses tab / Return in all the right places, etc.), I'd probably buy it.

But on Windows, Yubikey is just too expensive for the software. I can't believe, given how little it does and how "third-party" it still feels after you've installed, that it costs that much to develop the Windows side of the software.

Well, unless someone sits and writes specific modules for each possible underlying instruction set, probably not.

Remember, Android is Java - sure, you CAN execute ARM (or in some hardware Intel) instructions - but those are always of the processor-specific modules. Go download the MoboPlayer app, which has specific modules to accelerate video for each type of device.

Can't see that happening for an emulator, especially when 99% of the time, the performance in Java would be fine anyway. Thus, you're really asking if someone is going to bother to write, say, an emulator for a cutting-edge device that a PC would struggle to emulate, plus specific ARM modules to make it run at feasible speeds. And the answer is probably no, especially when the market moves this fast.

Going into business with friends or relatives is not a problem.

Just treat it like a business. When your cousin comes to work for you, you're under no different obligations as an employer than you would be if they weren't you cousin.

Similarly, business is something which people do for "profit". Whether than be salary, experience, shares, or literal profit - each person is there because they have something they want out of the business. As such, pretending that because they are family makes things different is idiotic.

The friend who says to his friends that he hired "Sorry, mate, it's not working out" is still a friend, but he's protecting his interest in the business. A friend that doesn't understand that is not a friend. And though there might be "favours" and shortcuts and digging people out of holes, those favours are as shortlived in the business world as they are in the personal world - and abuse of them by a friend means that they aren't a friend.

Speaking as someone who has in the past hired my own brother (and will do so again soon), and who my father found me work for occasionally with good friends of theirs, it's still "just business". They're not giving charity - if they were, they'd give charity as a friend.

If you go into business with a friend or relative, treat them like anyone else. Get a contract, get them to sign it, talk to them about what's happening, don't just assume they will always do what you want even when it's not in their interest. Don't rely on even a friend's goodwill to get you through.

You wouldn't take money from a friend just because they offered it. Equally you wouldn't run up a debt for your friend just because they "normally pay" or whatever. Talk to people. And get anything business-critical in writing.

Some guy you know coming to work for you for a few days can go wrong enough - don't think when you're talking multi-million dollar businesses and official share certificates that you don't need to make things official too.

In this day and age, I don't really care.

I prefer Steam because, generally, programs don't put more DRM on than the default Steam stuff (which is non-intrusive, as far as I'm concerned).

Origin, I can't stand the poorly-designed program that once downloaded something like 40Gb and took nearly a day to install one game, because every update was applied sequentially and every update updated every file, sometimes 9Gb per update.

But the end-point DRM on the game? You either care what that is and Google it, or you don't. That it's on a "free" game or not, who cares? And Securom is a damn sight better than shite like Games for Windows Live.

I can't say I've ever seen a machine "messed up" by Securom, certainly not one that can't be fixed by removing it (tricky though that may be).

As far as I'm concerned, the average bit of freeware comes with crap worse than Securom bundled nowadays. Hell, have you tried stopping Google Update services being created every time you install Chrome or Google Earth? It's a nightmare that DOES affect things.

Flashy IDE's probably aren't going to be easy to find, there weren't many around in the first place and the majority of stuff I know is just command-line compilers which can plug into any IDE (if you're brave enough).

All I remember of Palm coding was having to break C files into tiny parts, jam them together and hope the individual object files never went over a certain size because the linker had to play all kinds of tricks to load them.

In Britain the DVLA are looking at their policies.

Drivers who have had eye surgery are generally marked as never requiring corrective lenses. But the DVLA have found numerous instances of drivers eyesight falling below minimum standards after laser eye surgery.

This laser eye surgery is not, in all people at least, permanent.

Obviously, in the DVLA's case, their answer is "We don't care... if you're below minimum standard - whatever the reason - you need to report it to us and wear some kind of corrective lens until you can prove otherwise". Which is sensible.

As a glasses wearer all my life, my eyes have stabilised. But laser-eye surgery is not only vastly oversold by marketers posing as doctors, but also not permanent. I could spend several thousand pounds and risk my eyesight (no surgery is without risk) in order to get out of a habit I've been in for the last 20 years that doesn't actually affect my life often at all (my prescription is unchanged for 10+ years, I've had the same three sets of glasses - including sunglasses - for 10+ years, I rarely break things like that, and the microsecond it takes to put them on in the morning and take them off at night is negligible).

That's why.

One small step for man, one giant stumble for mankind.
