Hey, I went for a walk this morning and found a nice shiny stone.
I like my shiny stone - it's great.
So, like, I saw this online competition for best "mashup" and entered my stone as it is bound to win, what with it being so shiny and cool.
Hang on, they say they have rejected my entry because it is not a "web application". WTF?!?

No, SpecatateSwamp does not exibit the common symtoms of Asperger syndrome (or Asperger's syndrome). He fits the pattern of Schizophrenia much better.
I am qualified to say this because I have been diagnosed with Asperger syndrome.

RE: Best Linked List Ever

I don't know which variant was Wirth's, but the standard trick is the delta-linked list:
struct node {
void *obj;
int delta;
};
Now that's just silly - we know this project is using embedded Linux, so an int should be 4 bytes, the same as a pointer. All you have saved is 4 - 4 = 0 bytes. But the code is much less obvious.Um... assuming you replied to the right post, that's an example of a doubly linked list taking up the space of a singly linked list. It's not about saving space.
What? You say two things:
a) "...that's an example of a doubly linked list taking up the space of a singly linked list."
b) " It's not about saving space."
Which one did you mean?

RE: Certified secure
Not sure about other countries (but sure most Western ones have similar):
[QUOTE User="Computer Misuse Act 1990"](1)A person is guilty of an offence if—
(a)he causes a computer to perform any function with intent to secure access to any program or data held in any computer, or to enable any such access to be secured ;
(b)the access he intends to secure, or to enable to be secured, is unauthorised; and
(c)he knows at the time when he causes the computer to perform the function that that is the case.
...(3)A person guilty of an offence under this section shall be liable—
(a)on summary conviction in England and Wales, to imprisonment for a term not exceeding 12 months or to a fine not exceeding the statutory maximum or to both;
(b)on summary conviction in Scotland, to imprisonment for a term not exceeding six months or to a fine not exceeding the statutory maximum or to both;
(c)on conviction on indictment, to imprisonment for a term not exceeding two years or to a fine or to both.[/QUOTE]And just for fun:
[QUOTE USER="Criminal Law Act 1967"](1)Where a person has committed an arrestable offence, any other person who, knowing or believing him to be guilty of the offence or of some other arrestable offence, does without lawful authority or reasonable excuse any act with intent to impede his apprehension or prosecution shall be guilty of an offence.
[F1(1A)In this section and section 5 below “arrestable offence” has the meaning assigned to it by section 24 of the Police and Criminal Evidence Act 1984.]
(2)If on the trial of an indictment for an arrestable offence the jury are satisfied that the offence charged (or some other offence of which the accused might on that charge be found guilty) was committed, but find the accused not guilty of it, they may find him guilty of any offence under subsection (1) above of which they are satisfied that he is guilty in relation to the offence charged (or that other offence).
(3)A person committing an offence under subsection (1) above with intent to impede another person’s apprehension or prosecution shall on conviction on indictment be liable to imprisonment according to the gravity of the other person’s offence, as follows:—
...(d)in any other case, he shall be liable to imprisonment for not more than three years.[/QUOTE]
So if this had happened in the UK then anyone who committed the act would be liable for up to two years in prison, and anyone who deliberately helped that person evade justice (say for example by witholding their name when recounting the story) would actually be liable for up to three yers in prison!

RE: Video powered case fans
@ender said:
Not really that surprising - there's some current leakage through the cable, and the 5V rail is often shared. I've seen USB hub power the chipset fan myself.
I wouldn't exactly call it "leakage" the OP has connected a cable that is used to provide a 5v power supply to one device to the 5v rail of another device. He may as well have clipped a bench PSU to a 5v test-point. -
RE: Video powered case fans
Pin 14 of a DVI cable supplies +5v power to a monitor for use when in standby. If you connecta DVI cable from one PC to another then you link the +5v busses of each computer. Any devices powered from this 5v bus would try and use power via the DVI cable.
Actually I am pretty certain that the way modern PSUs work not all the 5v supplies are directly linked, so this is not guaranteed to happen depending on which output is used for each device - but it does not surprise me at all.

That's actually more like 10 sockets per room. US outlets are usually two sockets per outlet. The rule of thumb is an outlet every 6 feet (I think NEC requires no cord to be run for more than 6 feet). US homes also usually have dedicated outlets for appliances (of varying current capacity and voltages). Also, kitchen counters usually have several outlets and multiple circuits to accomodate microwave ovens, toasters, etc.
Sockets in the UK are usually paired, and count as two sockets.
Are US double sockets on the same circuit? If so it would be interesting to know how often someone plugs a kettle into one and a toaster into the other - which is a common situation in the UK.

RE: Rental Electrician
In the UK, appliences such as this 3kW electric heater are common:

Also - a three room apartment with only 15 sockets? So 5 sockets per room on average? The room that I am in has 12 sockets, and that is not generous for the UK.

RE: Rental Electrician
Very few people seem to understand the reason that UK plugs contain fuses - they are to protect the cables. The principle is that any cable must be protected by a "protective device" (i.e. a fuse or breaker) that will trip before the cable is damaged by high current. The cable entering a property could be safe for hundreds of amps and is protected upstream, then there is main fuse, usually 100A. This means that anything after this fuse must be able to function safely while passing 100A - this includes the main switch for the property, the meter, consumer unit (fuse box) and cables connecting them. In the consumer unit there will be breakers (usually at 32A) which feed ring mains. This means that the wiring for each ring must be able to safely pass 32A. A ring will contain many sockets, and what happens from that point onwards depends on what the homeowner wants to do. A typical example may be a 2kW electric heater being plugged in - this has a design current of about 8.7A. The question is, how much current must the cable to that heater be able to safely take? You have to assume that a fault could develop in the heater causing it to draw more power (a common fault in a heater). If there is no fuse in the plug, then the cable has to be safe at 32A because that it what it will take to trip the breaker. This would not be a good solution, so in this case the plug will have a 13A fuse, and the cable will be designed to be safe at 13A. Note that even though the design current of the heater is less than 9A, the cable must be rated at over 13A as that is the "fault current" for this device (determined by the fuse in the plug). Where it gets even more interesting is where I want to plug in a radio taking a couple of watts (about 10mA). Here I can have a plug with a 3A fuse, and size my cable for 3A rather than 13A. To understand why this is important, consider the fact that 13A cable is fat, expensive and not that flexible, but 3A cable is thin, cheap and considerably more flexible.
So, why not use the US system and have a breaker for each circuit and noting in the plug? Firstly a typical UK house might have well over 100 sockets, each able to supply 13A if required (not all at once obviously, but you should never be far from a socket that can supply you with 13A if required). Even if you were to put 10 sockets on each breaker, that would require more than 10 breakers for sockets. Assuming that you use 15A breakers for each of those, it will be difficult to be sure whether any socket can supply you with more than 8 or 9 amps without knowing which other sockets are on the same breaker. For a 13A socket on a 32A ring to not be able to supply 13A, there has to be over 19A used elsewhere on the same ring; for a socket on a 15A circuit to not be able to supply 13A, there only has to be 2A use elsewhere on the circuit. Also, to give the same protection as UK wiring, every cable on every device must be safe at 15A, and my understanding is that this is not true of most devices in the USA.

RE: Else return null
@Jaime said:
My bigger pet peeve is; why return null instead of an empty list? I think an empty list or an exception are both easier to handle than to have to check for a "null bomb" every time the method is called.
I disagree - to me returning an empty list means "all went well, and the following is the list of zero results", returning null means "something went wrong"
