It looks like these books are hard to find new, but can be found second-hand online.
Many of the suggestions above are good for somebody who already has a grounding in basic electronics. Horowitz and Hill is a great text book, but it lacks the practicalities a beginner needs to translate a circuit diagram into a flashing light on the table. Tom Duncan provides the walk-through you asked for, as well as the explanations.
For the absolute beginner (which is about the level of GCSE physics), I recommend the books I started with. Look for Tom Duncan's "Adventures with Electronics". As well as circuit diagrams there are clear illustrations so that you can start building working circuits right away. The workings of each project is clearly explained, and followed by suggestions for expanding or altering the circuit to do something different. It's very rewarding: you don't need to understand the circuit before you start, but you certainly will after experimenting with it.
After the first book, there's "Adventures with Micro Electronics" and "Adventures with Digital Electronics" which introduce ICs and binary logic. Once you've got through these three books, you'll be sufficiently well grounded to pick up standard electronics texts to progress further.
Each book comes with a list of components which you can easily order from Maplin or RadioSpares. It's cheaper than buying a ready made kit, and the components are better quality than many of the kits (which will save you many frustrated hours). Any anyway you'll soon be buying more components to make larger circuits and your own ideas.
"That's an interesting rock, let's look a bit more closely... woah, no time for that, we're off again."
"It sure is windy today. I feel a little seasick."
"Was that a pair of eyes we just went past?" [sometime later after a change in the weather]
"The forecast is calm for the next month. Has anybody got any great ideas for studying this patch of sand we're stuck on?"
Here we are, years later and it is still working. It isn't as though this is a panic "Oh no we have to save the mission!" kind of thing.
The very fact that Spirit has worked so tremendously well up to now means that it is still an extremely valuable device. It's worth spending every effort to save the rover now, precisely because it has shown itself able to surpass its original goals by so much. In other words, age has increased rather than decreased its worth.
5. There's no checkpoints to get to the checkpoints, [...]
Whatever you think of US airport checks, there are plenty of countries with much more elaborately ineffectual security theatre. I've just returned from an airport where there's a checkpoint to access the checkpoint to get to the checkpoint before you can check in. I'd lost half of the papers I was supposed to present, but it didn't seem to matter.
Lots of recommendations here for encrypted VPN tunnels. But assuming the bank uses HTTPS, why would you need the extra layer of encryption?
I don't agree with those who say leave the netbook at home. Using a live-CD to avoid keyloggers in internet cafes is not always possible. Often the CD drive and USB ports are removed or defunct. Come to think of it, the keyboards are often defunct too. With wired or wireless connections increasingly available, a netbook can be very useful. Just keep a copy of any important data on a memory card in your money-belt.
The algae fuel industry has to develop itself from nothing, to a point where it can compete with perhaps the biggest, richest and most developed industry in the world. And it has to do that with no income beyond research grants and investors. I say, "They need only ten years?"
you can try muddy the waters all you want, but if you've got a pair of nuts, your not female.
Eh? I don't think you read my post.
Running shorts don't hide much, and I don't see any "nuts". Urine tests are given under supervision and without shorts, and still nobody saw any "nuts". If the authorities still have any doubt, they should be doing their tests before talking to the press. Whatever the outcome, the current fiasco is likely doing real harm to Semenya, and does nothing for the credibility of the sport. That's nuts.
Semenya is a woman who has every right to feel badly treated. Apart from anything else, athletes are closely supervised whilst undergoing urine tests, and any physical ambiguity would have been spotted long ago.
It's clear that there has been no deliberate deception here.
If tests were needed, then simple human decency should have required that they were done privately and discreetly.
Questioning her gender, in the most public and humiliating way possible, is absolutely disgraceful.
As the previous poster points out, you're allowed to have good genes.
And even if Semenya does have an extra Y chromosome, that's not against the rules, and it may not even be an advantage, as this article explains.
Light a flame - the heat isn't at the yellow outer edge, it isn't in the centre, it's precisely where the blue cone terminates. Why should the sun be any different. Yes I know it's a nuclear phenomenon, but FFS, the evidence stands for itself. Oh, sorry, this is Discovery science on/. these days. maybe I should swear and say wow a few times !
Well you've got the invalid-analogy and the proof-by-assertion already, so why not? I look forward to seeing you on TV.
Actually , Truecrypt can be used as a stand alone executable , which could be put on an external medium , like a usb stick.
And there are USB keys small enough to swallow. For best results, chew first.
All this talk of eating cipher keys reminds me of the good old days. Back then you hid your data in a microdot, and there was no snotty sysadmin to lecture you on security by obscurity. There's never a cold war when you want one.
There are few situations where a bicycle wouldn't be a better, cheaper, and more efficient option. The segway is cool, but it's a solution looking for a problem. It's over engineered, too expensive, and in the vast majority of situations offers no benefit over the alternatives.
You could say exactly the same about almost any gadget, from telephones to lemon-squeezers. I don't have a Segway, but I do have a bike. It's fancier and more expensive than I actually need, but it's a cool toy which is fun to use. And that was enough to justify buying it.
OK, so maybe not. One of the best, and least-quoted reasons to believe that the moon landings were genuine, is the way the dust was kicked up by the astronauts and the lunar rover. It follows a perfect parabola -- something dust in an atmosphere never does. So, NASA might have built a humongous vacuum chamber, big enough to contain a studio... But eventually it becomes simpler to go to the moon for real.
If you've got balls enough to be a NASA astronaut, you don't have "oh shit" moments. Armstrong famously took manual control of the Eagle and landed with just 45 seconds of fuel remaining.
But even I have to question the sanity of pouring billions and billions of dollars into an organization so fscked up that they have to reinvent technology they provably had over forty years ago, and who keep losing people and equipment because they refuse to listen to their own engineers.
Standards have changed since 1969. The Apollo programme was expensive and dangerous. Building another Apollo mission today would still be expensive and dangerous, and worst of all it wouldn't meet modern ambitions. NASA is looking at building an inhabited lunar outpost, visiting an asteroid, launching a large deep-space telescope, and a mission to Mars. It might be a short hop from the Moon to Mars on a poster of the solar system; in real space it's a whole different prospect. Doing new stuff requires new technology.
This is a lazy instructor working to maintain his laziness.
Do not underestimate the work involved in preparing a new course. I teach for a few weeks every year, and can easily spend several days preparing a new one-hour lesson. Even recycled material needs updating and revising, and the preparation time is at least equal to the teaching time. Think of the time you spend to prepare a presentation at work. Now imagine spending your whole working day giving presentations, and doing the preparation in the evenings.
Teaching is a tough job, and only those who believe it's important stick at it. Some teachers are more talented than others, but I've yet to meet a lazy one. A lazy teacher will quickly move to an easier (and better paying) job.
My name is Sam Tyler. I was born in 1973, and my parents never fitted me with a tracking device. Were they mad, in a coma, or back in time? Whatever happened, it's like things worked out anyway. Now, maybe if I can work out the buses, I can get home.
Cern should be CERN, as it stands for "Conseil Europeen pour la Recherche Nucleaire"
Actually it doesn't.
The Conseil Europeen pour la Recherche Nucleaire was a provisional body created in 1952, and no longer exists.
In 1954 the European Laboratory for Particle Physics was founded, and the C.E.R.N. was dissolved. The laboratory is named CERN, and although it is conventionally capitalised, it is not an acronym.
On the other hand, saying that the FSF is "dedicated to eliminating restrictions on copying, redistribution, and modifying computer programs" is extremely accurate.
That would imply that the FSF is attacking the right to create and sell non-free software. That would be a bizarre goal, and as far as I can see it is not the case. However I can see why the RIAA's lawyers might want to ascribe bizarre aims to an organisation they wish to discredit.
The FSF appears to be concerned primarily with protecting our right to publish and use free software. What's truly bizarre is that these rights should even need defending.
Anything that radioactive would corrode to oblivion within a few years. Ionising radiation destroys crystal structures and stimulates chemical reactions which would not otherwise happen - which is what make radiation dangerous in the first place. Even stainless steel, after long exposure to high levels of radiation, will oxidise and crumble.
Employers are increasingly trolling the web for information about prospective employees
No they are not - "trolling" means "posting controversial, inflammatory, irrelevant or off-topic messages in an online community", which is a lot closer to what kdawson is doing with this.

I record garage bands. You don't need a click track for multi-track recording. Take a demo tape and use it to get the drummer to play his track. Use the drummer as the click track for the rest of the sessions.
That's OK if you aren't going to do any time-shifting.
The advantage of the homogeneous tempo provided by the metronome is that you can chop up and rearrange
each track as much as you like, and still have the final mix line up.
Blazing sunshine at midday at the top of a mountain on the equator?
On a moonless night?
Or could it even be 1W/$ averaged over a year under typical working conditions at, say, a latitude of 45 degrees?
The difference between maximum and average output could be huge. Direct sunlight can be more than 100x stronger than the light on an overcast day. Given the wild claims we keep hearing from pseudo-green con-men, I'd like to see some more data.
