Ok I can spend 17p on a cheap 60w or 100w incandescant bulb.
Or I can spend 5 pounds on one of these energy saving bulbs (well I have seen them as low as 1 or 2 pounds I will admit)
In theory they are cheaper to run... in theory.
Incandescant bulbs "waste" a lot of the power put into them. But what form does this waste take exactly? Heat.
So I can either have a 23W bulb which generates little or no heat, or a 100W bulb tht generates say 25W in light and 75 in "waste" heat.
But is this heat actually wasted? I don't know about you but I live in the UK - In the summer we have nice long light evenings (most of my american friends commend on how long it stays light) so the need for indoor lighting is limited. The rest of the year its cold. you have the central heating on. I don't have any gas heating, its all electric, its also on a thermostat.
So if the 75W of "waste" heat don't come out of my light bulb... then it is going to come out of my heaters - there really isn't any savings here.
Add this to the fact the the CFLs are more expensive to produce, contain heavy metals that are environmentally damaging to dispose of and, unless you buy the more expensive ones, have the anoying warm up delay and frquently don't have the same quality of light output. Incandescant bulbs on the other hand are very simple to produce and to dispose of.
Ok I'll concede running incandescant bulbs at the same time as running an air con is just plain wasteful, but I don't and doubt I ever will. The suposed savings of these bulbs are not always well thought out as a household is a lot more than just a light bulb.
Remember that when lucas wrote the original star wars trilogy he had the help of a professor of mythology, a close friend of his. This is why IV-VI play like epic mythos.
Unfortunately he died before I-III were written, even more unfortunately lucas went ahead anyway.

On the whole I regard wikipedia about as useful as the google search of usenet.

Actually thats only true in secret single key cyphers - having the plain text (the disc key) and the cypher text (the encrypted disc key) gives you a point of comparison.
Obviously if you are using something like a ceaser cypher its now trivial to get the player decryption key.
With public/private key cyphers you are given the public key. This means you can have an unlimited number of plan text, cypher text pairs and in theory it will still not get you any closer to discovering the private key than when you just had the public key.
I doubt that these data points will be particularly useful in decoding the entire collection of player keys.

Ok so they are heavy and take up a lot of space... I have a big desk and work out - its not an issue.
For the living room? Well given the choice I'll go for a couple of projectors, a media linux box and a remote control for the curtains and the screen.
I have to admit I had a problem with my ubuntu setup accessing the wireless network - it just wouldn't connect...
Until I removed the space in the ESSID from "Private Network" to "PrivateNetwork" I suspect ubuntu has a quoting issue on the system call to iwconfig (assuming thats how it works)
If I ever get time to test this properly and confirm it I'll raise a bug report...
You can fix needing to run your cd burner as sudo by either:
easy way: SUID root your CD burner software (major security risk though - atleast in unix terms, no worse than always loging in as admin under windows) slightly harder but much more sensible way: add group rw permissions to the CD burner device and make sure your user is a member of that group (I'm actually a little surprised and disappointed that that is not the default on ubuntu...)
I always drive rental cares, and I have a zero excess on them:)
I do the exact same as you - and frankly I really could not care less if they dent the body work trying to force their way in I dont plan to move out of their way - the car isn't mine, I can't lose any no claims and it wont cost me a penny to fix.
Its a variation of "the car with the worst body work has right of way" rule;)
You can't actually patent drugs (atleast in europe, god knows what you can and can't patent in the US)
A drug is only a chemical molecule merely arranging atoms in a new way isn't considered novel.
What you can patent is the method (and apparatus) of manufactoring that drug, you can also trademark the name.
An interesting point is that in India (due to the sacredness of life in bhudism and hinduism) its illegal to have a patent on something that can be used to save lives. This means any company can manufacture and sell clones of any drug of the market (and since patents by definition have to be exact descriptions of how to make said drug its not that hard once you have the right lab equipment) under the various internation treaties (WTO included I think) they are not allowed to export any of this - but their own laws are honoured with their own country - so internation patents on life saving drugs are not - only life saving drugs though so you can't get cheap viagra there - I'm sure if you look in your inbox though you'll find plenty of suppliers;)
until the point of patenting most companies keep their info secure - this system means that they patent at the point of release. Just the elvel of security changes.
The alternative is to patent, sit on it for a while, scalp any other company that wants to do similar for license fees, maybe eventually sell or use the patent yourself... maybe
Try the japanese system - you get two years to exploit an idea with protection from so that no one else can use your idea in that time.
At the end of those two years, if you are actively exploiting the idea in a business you can get another 1 year of protection and thats it
The principal is that if a 3 year head start on your own idea isnt enough to get you established in the market then you should probably let someone else do it anyway rather than stifle future innovation
(companies also have to keep their R&D far more secure under this system and they only usually patent just prior to launching to market - this in turns requires a much faster and streamlined patent application system)
Any idea if it is countably or uncountably infinite in size according to current thinking?
And is it growing within the same cardinality of infinity or is the cardinality increasing
Or is this something that we aren't even ready to think about yet?
(just incase people think I have gone completely insane countably infinite is aleph null or aleph zero and iirc is definited as being able to create a 1 to 1 mapping with the natural numbers, so N is countable infinite, as is Z and Q. R and C are uncounably infinite, R is described as having a cardinality of aleph-1 - without having a text book infront of me to quote from I dont feel comfortable going into any more detail)
Yep, the biggest wind farm has a peak - yes peak, ie only when there is wind which is not all the time - output that would barely match 1/4 of Drax (the UK's largest coal power station)
Not to mention the question of what to do on a no wind day... or worse several days of no wind (since for short term lapses gavity batteries using hydro electric generators could be used, pumping water up hill when power is plentiful, using it when power is needed, a system already used to provide peak power boost in the UK)
Following the link to the london array project gives 1GW peak power for 271 turbines which could power 750,000 homes (I assume the other array must produce 500MW to power the other 250,000
This should mean that the new media mesurement of 1Hp (House power) is equal to 1.33KW peak power....
Bear in mind they were tyring to teach coding theory and coding practice - the language is really incidental.
Going out of their way to make things equal between students is fairly common in UK universities - little differences such as the fact you NEVER put your name on the exam paper and the marks are stadardised across the university. Not to mention 70% being the top grade (but the exam being designed such that if you only know what was taught on the course and you didn't do more research you could only get 70%)
Very different to the year I did in the states.
Knowing ADA isn't really a handicap - its a very robust language and if you ever go contracting for the military it will probably still come in handy.
I've seen (and had to maintain or more frequently rewrite) perl written by people who did perl as their first language - its obvious in their code.
Yes perl is a great language. Its a good teaching tool as you can do pretty much anything in it, very quickly usually - from low level C style manipulations to OO and regex.
But perls flexability is its downfall. The difference between what you can do and what you should do is huge. Perl has a very bad reputation for unreadable code (executable line noise) and while experianced perl coders trying to make obfuscated code can come up with real gems, programmers that picked up perl as their first langauge and never learn the difference between can and should really illustrate why learnign a stricker formal language first works much better in the long run.
Nothings wrong with python, I think its a great language, though personally I prefer perl. However I do not think either perl or python are suitable first languages. They need to learn something with good in built discipline first. Both perl and python allow bad coding practices far too easily, whereas you can write very good code in them, but its better to learn the discipline first.
VB is in the above list for a different reason - its full of bad practices and bar being able to create GUIs quickly has very little to redeem it as a formal programming language.
Maybe its a difference between the UK and US... my high school taught C to anyone who wanted to join the optional cource in 6th form (equivalent to junior/senior year) BASIC prgramming was used at GCSE though most of us on the course learnt that many years before on C64, Spectrum 128 or even amstrads.
I know I found when I did the 2nd year of my degree in the US that US college freshman/sophmore courses tend to be on a similar level to UK A levels (at least how they were when I took them, they seem to have gone downhill in recent years) and that to keep pace with my UK university requirements I had to tak mainly senior/post grad courses.
I think blinding them with too much prewritten libraries is a bad thing personally.
Let them get used to the old way of writign their own libraries, give them a real grounding in where programming came from, and a real sense of acheivement in knowing that what comes out is all their work, rather than just a few hooks into some one else's library - like learning to cook from raw ingrediants ratehr than using a shake and bake kit.
In univeristy the text book I used was Data Structures and Algorithm Analysis in Ada - Ada was just picked by the university to ensure no student had an advantage from already knowning the language as it is rather obscure - it is also a very strict language to write in.
I found the text very good and the same author offers the same text aimed at C (though I will admit I have never looked at the C version, though I suspect it would be similar to the Ada text in most places)

But the hardware key wasn't cracked.
It was decoded by a piece of software, the result held in memory and this result (ie the disc key) pulled out of memory
So all you have is the title key and lots and lots of copies of the title key crypted by various hardware keys that you dont know
Actually thats only true in secret single key cyphers - having the plain text (the disc key) and the cypher text (the encrypted disc key) gives you a point of comparison.
Obviously if you are using something like a ceaser cypher its now trivial to get the player decryption key.
