If I break a new XP2200+ chip by overclocking it, that is a lot of money. If I break my Athlon 700, it isn't, they can be picked up at under £20 now. I don't mind pushing the chip to it's limits, because of that.
Also, now I can buy PC133 or even PC150 ram very cheaply. It's easy to push the bus further and further. I can put 1.5GB of memory in my computer for less than £150 and make it go very fast.
To be fair, this computer I am using at the moment goes better than most others because I have a lot of memory which goes quite quickly. Not as fast as DDR or RAMBUS, but because I have more of it, no swapfile....
To be fair, a far better way of cooling RAM is to buy a bulk pack of stick on finned heatsinks for SOICs (or DIPs). They would need to be low profile to fit, but the finned area would be far greater than with these heat spreaders. They are also normally black, and although this will reduce the amount of heat transferred to moving air (which is essentially conduction at the surface), it will allow heat to be radiated quicker, so without forced air cooling they will be better.
I've thought about doing it for a while because my RAM gets fairly hot. It's PC133 and it's going at 145Mhz now, but I think I could get it up to 155Mhz if I tried.
There is still a point in overclocking as well - as my computer gets older, it's more and more economical for me to push it further just by spending £10 on a few cheap heatsinks....
Geeks with no electrical knowledge?

The article at ExtremeMhz with the relay controlling the four way is pretty bad. Messing with mains voltage if you do not know what you are doing is stupid - and things like this encourage people.
First off, the bit about the relay mentions that there is an AC side and a DC side. WTF? There is a coil, and there are switch contacts. Next, he says that they are rated in current and voltage. Yes, true, but a voltage for the coil, and voltage and current ratings for the contacts (for AC and DC). A "12V 10A relay" means very little. I have what could be described as a "12V 45A relay" here. It has a 12V coil and will switch 12V at 45A. Not mains (110V or 240V). See how easy it is to get this wrong when people just copy your article.
In this country (UK), a 10A relay is not enough to power a four way. A maximum of 13A can be drawn through a plug, so you would need a higher current rating on the contacts of the relay. I do not know about the US, but because it is 110V, I would assume currents to be higher. This relay is probably quite inadeqate.
And if you have to tell someone how to drill a hole into a plastic box, surely they aren't competant to play with mains?
Moving on. He mounts a mains voltage relay inside a plastic box with absolutely no regards to strain relief on the cables. All it would take is a trip on the four way and the cables would be yanked out the box, possibly leaving live conductors bare. Not good at all.
Also, those "quick disconnects", which are called spade connectors, should be covered by a plastic shroud when they are used on a relay such as that. There is the possibility of the 12V wire coming into contact with mains, which would have dire consequences. Also, try fixing the relay into the box...
I'm just not keen on the number of people who write things like this, essentially idiots guides, which people blindly follow. They aren't a good idea when people can get hurt.
It reminds me of a rudeboy car magazine I read which showed you how to install NOS into a Citreon Saxo. Drill this, thread this, this colour wire goes here, etc. No explanation of how or why... quite ridiculous really.

You don't get it.
It turns on a multiway mains adaptor (powerstrip, four way etc.)using the 12V as a signal from your PC, so everything will go on and off at once. The power does not come from the power supply in the PC.
Are the "*"s round the "is" to highlight the fact that the grammer is wrong?
You should have said "Tapes are the right media for long term backup" or "Tape is the right medium for long term backup".
Yes, it doesn't validate. However, it does display fine in all browsers. The validation problems are with ALT tags (which I feel have no point, because if the images aren't there, then there is no point looking at the site), and the webring code which isn't mine. Yes, I've missed some inverted commas, but I don't really care. It works.... I'm not spending my life writing perfect websites, seeing as there are so many out there that are far worse.
Yes, tables were designed for tabular data. However, they are widely used for layout. I learnt to use them that way, it works on modern PCs that can render nested tables and the like. I know someone who converted their site to work with div tags, and now it displays differently in different browsers. Who wins?
What about people too poor to use the internet? People who are starving? Should they get access to my website off my back? No.
My website is about urban exploration. It interests other explorers. They are not wheelchair bound as it is a near impossibility to do UE in a wheelchair.
And no, my opinion is not worthless. It is my opinion, and I am allowed to hold it. You may think it is worthless, and I don't really care.
Surely life is about dismissing and ignoring people? People who claim they don't are lying. No one has entirely altruistic intentions. You can't deal with everyone, it wastes your time. People always stereotype, even if they deny it. You don't have time to think about everybody all of the time.
What about newspapers, magazines etc. ? Surely getting them accessible is far more important.
Bus stops are on the sides of the road every couple of hundred metres. All you do is call the travel information lines, find out which buses wheelchair users can get on, then go to the nearest bus stop. The whole bus lowers down to kerb level and a ramp goes from the door onto the pavement. I cannot see how it can be easier.
There were talks of making all underground stations accessible to wheelchair users. Most stations do not have lifts, and most trains come in at different levels to the platforms. It would require platforms to be raised and lowered, lifts to be added etc. Don't even try thinking about the stations where 3 different sorts of rolling stock use the same platform.
The costs are immense. The people who can use it don't. So why should my train fares and taxes go up? They shouldn't.
And my website will stay as the graphics intensive thing that it is.
If you can't look at a website to read it, get someone to read it out to you. With the amount of shit on most sites, you'll need to cut out a lot of advertising anyway....
This is probably going to offend a lot of people, but then I don't really care.
The proportion of blind/physically handicapped etc. people who use computers and the internet is very low. It seems like a lot of effort to make websites that they can "look" at, so is it really worth it?
My website inherently has a lot of images on it. It isn't the same without them, and I know for a fact that they aren't possible to convey to a blind person. So why should I develop for them?
I also don't support older browsers for the same reasons - if they can't display the site effectively without a lot of effort then I can't be bothered.
A similar situation has occured in London. There was a drive to make public transport more accessible to disabled people. This involved a lot of new buses having lowering decks to allow wheelchairs on. I have never, ever, seen one used by a wheelchair bound person. Some statistics show that each journey by a wheelchair costs several hundred pounds because of the extra costs involved with the design and implementation of disabled friendly facilities.
And surely the use of websites is one of the smaller problems? I can't see Windows being an effective method of working without sight. Maybe it would be better to start from scratch.
Most of this discussion seems to have veered off onto how cheaply you can get dry ice. Over here in the UK it is used rarely for theatrical effects, for many reasons.
It's awkward to store, and will sublime even in a freezer. The room you store it in needs to be ventilated or dangerous levels of C02 can build up.
It's hard to control. Most people just pour hot water onto it. There are some better commercial devices that heat water or whatever, but it is hard to turn the fog on and off.
It stays for a long time. Quite often people want the low lying fog to go before the next scene. Dry ice based fog remains for a long time.
Fog chillers however don't have these problems. Yes, the fluid for them costs a fair bit (up to £60 for 5 litres), but you can control the flow, density, and type of fog. Some machines will do chilled fog, smoke, and haze (very low level smoke, used to show beams of light). You can sit at the other end of the room and control it remotely using DMX. It disperses very quickly as well, so when you kill the machine, the fog is gone very very quickly.
Saying this, there are now machines that use C02 cylinders which solve a lot of the problems of solid dry ice.
Dry ice is also better for on stage effects (witches cauldron) and practical jokes. We tipped a lot of C02 pellets down a toilet once, and found it quite funny when all the other toilets in the block started bubbling and smoking.
Why the fuck do people use e=mc^2 to prove everything? Information transfer is an energy transfer. There is no other way about this. Everything involves energy transfers. What the fuck has this got to do with the world exploding? And yes, information actually does have quite a lot to do with energy.
You really are quite dumb aren't you. Better to be silent and be thought stupid than to speak and be known to be stupid.
If you are using a computer, it isn't hard to type the entire word. Things like r -> are (or possibly our sometimes) don't save any time on a keyboard. Quite often I see abbreviations that work out only 1 character less than the actual word.
The other thing that comes hand in hand with the abbreviations are the lack of punctuation, capitals, or grammer. I have had entire e-mails with no capitals or full stops. It takes a long time to work out what is going on. And people claim they couldn't be bothered using the shift key (or whatever). Surely it takes more effort (if you ever learnt to type properly) to remember to not use the shift key?
I have kicked people off a mailing list I administer because they don't make any sense for the reasons above. I don't reply fully to e-mails, I just tell them to send it again so that I can understand it.
I also find that the people who send the mails like that tend to be quite stupid. I got an e-mail along the lines of:
"do u knw abt undergorund rails"
That was it. I asked what he meant by underground rails. The reply was like this:
"undergorund rails in croydon"
I again asked what he meant by underground rails in Croydon, as it is quite ambiguous, and the area very large. Response:
"my dad told me"
At this point, I wrote an e-mail explaining how much easier it would be for him to just type properly and explain what he meant. I think he wanted me to tell him all I knew about underground features in the area, but I couldn't be bothered because of his attitude.
Yes, there is a place for them on phones and SMS as they aren't easy to type on (even with practice, you can't do 80wpm on a numeric pad). There is also a place for acronyms, such as LOL, BTW, BRB etc. because they actually save a lot of time.
I can tell some bastard is going to send me SMS speak mails now just to wind me up...
Information transfer is essentially energy transfer. It is possible to make something change in response to something at the other end of the coax faster than the speed of light, but at the end of the day no information can be transfered.
So, in my opinion, this isn't going to make those electrons in your computers and comms links move any faster.... oh well.
Constantly I keep on getting spam mails from a company who claims to offer targetted advertising. The blurb on their site tells me how they always get it right, and it is the best way to advertise. So what do I keep on getting adverts for?
Penis Enlargement
I got one the other day telling me that my girlfriend thought my willy was small... otherwise they are really making sure I get the right adverts and my girlfriend is just being nice, or they are talking complete shit.
I have another model in the same line, and it is great. Got it two years ago from PC World for £100, and the toner cartridge lasted approx. 1500 sheets before it ran out, and the next one is going strong. Never any problems, and it has an old SIMM socket in the bottom of it so all you have to do is put some old memory in it. Means mine has 20MB in it and works great for all my needs.
Oh, and it actually does about 10ppm after it has warmed up, and because of the memory in it, never slows down from this. Fantastic thing.
Dvorak was still required to slow the typist dow - but it was thought that QWERTY wasn't the best way of doing it. I didn't say anything about when Dvorak was developed. And QWERTY certainly wasn't developed in the 1980s.....
Keyboards designed in the 80s? What are you on about. The QWERTY keyboard was developed in the 1860s not the 1980s, and it was a competing system to the Dvorak keyboard. Both were to slow down typists to stop the keys jamming on typewriters.
I understand how microwaves cannot cause ionisation.
80 years ago, microwaves existed, yet the concept of photons did not. We didn't fully understand them. Who is to say that someone won't come along tommorrow and have a far better way of describing them, that allows them to have many other effects.
And it makes no difference whatsoever to the fact that your brain relies on the flows of electric currents which will be effected by any radio signals.
Resonance in a physical cavity will result in high frequencies being produced.
Reflections cause a change in wavelength, and hence also in frequency.
Signals such as these in FM broadcast are not affected in such a way, as they are of low amplitude.
The Raman effect causes energy to move to otherwise higher or lower frequencies (I cannot remember which).
So it is perfectly possible for many thousands of components to be produced in the space close to the mobile that have significant power to affect other devinces.
I also did not say "adding multiple frequencies". The interaction between signals is far more complex than addition in the real world.
At the moment, in London, over 60% of muggings are to steal mobile phones. I know someone who had two guys attempt to mug him for his mobile, and when they found out he didn't have one, walked away.
Payphones also tend to be covered by the CCTV system where I live.
Transmitters, or transformers? "Substation" usually refers to an electrical substation.
Transmitters and transformers. I honestly believe that an the EMF off large substations can make you feel ill, and others two. I think it may be enhanced by a placebo effect.
Well, no, it doesn't. Just because something can kill you under the right conditions doesn't mean it's always dangerous. If I fire a bullet at your head with a gun, you'll probably die, but if I throw it at you you're not in any danger.
Throw thousands of bullets at me every minute of every day, however, and it may start to have effect. In the same way that smoking one cigarette may make only a little difference, but it does have some, on the length of your life
And it is all calculated risk. I know I'm not going to die from RF effects, I'm far more likely to fall off a rock or get run over.
People are scared by this stuff because it's invisible
Asbestos scares the shit out of me, and that is far more dangerous when it can't be seen. It was used for years, and no one gave a shit about it. Now it is treated with such care and respect....
Thankyou for that comment (actually thanks, not a piss take)- why should I carry a turned off mobile with me? I end up paying for a service that a don't use when there is a payphone or landline wherever I go and I need to use one.
If I ever go anywhere where I think I may get into trouble and need to call police/rescue, then people know when I should be back, and someone else with me has a mobile anyway.
So, in reference to the anonymous coward above, why should I spend £15 a month plus call charges, to keep a useless piece of equipment with me that increases the risk of being mugged, you "fucking dimwit".
As someone who has been in a few large substations, and near to high power transmitters, they do have effect on your body. You feel dizzy and ill after being near to these sites - there are no two ways about this. Many others claim this as well.
Phones may not do this to such a great extent - but open up one of the many "monkey drum" microwave dishes found all over the place in the UK, and the USA as well I should imagine. What do you find? A conventional cooking microwave magnetron. Ok, slightly different, and usually of a lower power.
Radar can produce huge bursts of power - and round radar sites, there are exclusion zones to stop you receiving a dose large enough to make you infertile or even kill you. Precision Approach Radar can be very dangerous in this respect due to the fact that the frequency and power used are dangerous, the dishes are located at ground level, and some of them can rotate 360 degress in seconds (the unit has to realign when different runways are used, and if you are in the way). Yes, this is an extreme case... but it still shows something.
I think that dismissing RF as safe because it doesn't cause ionisation or heating is stupid. In the same way as smoking was once viewed as safe, and that skin cancer has only been noticed very recently. Often our bodies do not behave in the ways which we think they should. I just think we should wait to see all the evidence before we jump to conclusions.
Surely electric currents in the brain are affected by RF? Do we know if this is bad or not? People also die when they are using their phone and can't pay full attention to the situation they are in.
Other issues are that when many radio waves are in a small space, they do not always combine to produce the same frequencies. Harmonics and other frequencies are generated, so saying that the frequency that the phone transmits is not dangerous doesn't mean the area is. Powers can also mount up.....
And jammers tend not to be high power - they disrupt the signal in a more clever manner. Although in the short term, the phones will transmit with more power, people will turn them off or the phones will stop trying so regularly.
I don't have a mobile. I don't want one mainly for the reason I don't want to be conctacted when someone doesn't know where I am. Landlines tend to be cheaper as well.
I realise that every brick is connected to the water cooling system, but is every single component in each brick connected to a heatpipe, which is in turn connected to the water cooling system?
As with any device containing air, the air will heat up. The insulation of the outside bricks and the lack of forced air cooling would not help this.

So it is perfectly possible for many thousands of components to be produced in the space close to the mobile that have significant power to affect other devinces.
I also did not say "adding multiple frequencies". The interaction between signals is far more complex than addition in the real world.
No, actually, you don't.
At the moment, in London, over 60% of muggings are to steal mobile phones. I know someone who had two guys attempt to mug him for his mobile, and when they found out he didn't have one, walked away.
Payphones also tend to be covered by the CCTV system where I live.
Transmitters, or transformers? "Substation" usually refers to an electrical substation.
Transmitters and transformers. I honestly believe that an the EMF off large substations can make you feel ill, and others two. I think it may be enhanced by a placebo effect.
Well, no, it doesn't. Just because something can kill you under the right conditions doesn't mean it's always dangerous. If I fire a bullet at your head with a gun, you'll probably die, but if I throw it at you you're not in any danger.
Throw thousands of bullets at me every minute of every day, however, and it may start to have effect. In the same way that smoking one cigarette may make only a little difference, but it does have some, on the length of your life
And it is all calculated risk. I know I'm not going to die from RF effects, I'm far more likely to fall off a rock or get run over.
People are scared by this stuff because it's invisible
Asbestos scares the shit out of me, and that is far more dangerous when it can't be seen. It was used for years, and no one gave a shit about it. Now it is treated with such care and respect....
Thankyou for that comment (actually thanks, not a piss take)- why should I carry a turned off mobile with me? I end up paying for a service that a don't use when there is a payphone or landline wherever I go and I need to use one.
If I ever go anywhere where I think I may get into trouble and need to call police/rescue, then people know when I should be back, and someone else with me has a mobile anyway.
So, in reference to the anonymous coward above, why should I spend £15 a month plus call charges, to keep a useless piece of equipment with me that increases the risk of being mugged, you "fucking dimwit".
As someone who has been in a few large substations, and near to high power transmitters, they do have effect on your body. You feel dizzy and ill after being near to these sites - there are no two ways about this. Many others claim this as well.
Phones may not do this to such a great extent - but open up one of the many "monkey drum" microwave dishes found all over the place in the UK, and the USA as well I should imagine. What do you find? A conventional cooking microwave magnetron. Ok, slightly different, and usually of a lower power.
Radar can produce huge bursts of power - and round radar sites, there are exclusion zones to stop you receiving a dose large enough to make you infertile or even kill you. Precision Approach Radar can be very dangerous in this respect due to the fact that the frequency and power used are dangerous, the dishes are located at ground level, and some of them can rotate 360 degress in seconds (the unit has to realign when different runways are used, and if you are in the way). Yes, this is an extreme case... but it still shows something.
I think that dismissing RF as safe because it doesn't cause ionisation or heating is stupid. In the same way as smoking was once viewed as safe, and that skin cancer has only been noticed very recently. Often our bodies do not behave in the ways which we think they should. I just think we should wait to see all the evidence before we jump to conclusions.
Surely electric currents in the brain are affected by RF? Do we know if this is bad or not? People also die when they are using their phone and can't pay full attention to the situation they are in.
Other issues are that when many radio waves are in a small space, they do not always combine to produce the same frequencies. Harmonics and other frequencies are generated, so saying that the frequency that the phone transmits is not dangerous doesn't mean the area is. Powers can also mount up.....
And jammers tend not to be high power - they disrupt the signal in a more clever manner. Although in the short term, the phones will transmit with more power, people will turn them off or the phones will stop trying so regularly.
I don't have a mobile. I don't want one mainly for the reason I don't want to be conctacted when someone doesn't know where I am. Landlines tend to be cheaper as well.
I realise that every brick is connected to the water cooling system, but is every single component in each brick connected to a heatpipe, which is in turn connected to the water cooling system?
As with any device containing air, the air will heat up. The insulation of the outside bricks and the lack of forced air cooling would not help this.
