>>>This is where the Raspberry Pi can save us: it’s now affordable for the government to equip any child in this country with a machine which they could take home with them and play with.

I have a problem with idealism like that. Andrew Carnegie thought if we had public libraries, it would enable people to help themselves. And where are we today? Education is free too, and where are we today?

I'm not saying that it might not help a small crucial group of children who -- through their own motivation -- will go on to do great things that will change their lives. But recognize that is the likely reality instead of pining for a universal enrichment that is never going to happen.

A chicken in every pot sounds good, but not everyone knows how -- or wants to learn how -- to cook.
In the case of Germany, they did the smart thing of promoting their products as "High Quality". Even today, German manufactured goods command a premium in the market (automobiles, power-tools etc). The British had an excellent legacy of quality engineering, I guess they have squandered it. (Although not related to manufacturing, I am reminded of a quote about British Civil Engineering I had read that said that "Americans build for 50-100 years, but the British build forever". This is quite true in India; a lot of the infrastructure laid down by the British is still in use)

EDIT: In responses asking for examples, see http://en.wikipedia.org/wiki/History_of_Mumbai#City_developm... . The British were responsible for merging the many Islands of Mumbai to get what it is today. Also, the pipelines supplying fresh water to Mumbai were built by the British and are being augmented only in the last decade or so.
I agree.
When I left my job as a games developer for a gig in the City my salary doubled.
I had zero experience in financial software and about 5 years as a professional game developer.
In that year I was the third developer leaving that studio for the City.
The work was less interesting, but I went from living like a student to having enough income to live independently in London while saving enough to start my own business.
The only software jobs in the UK that approach the US in salary terms are in the City.
Yes, overtones exist, and yes, overtones affect the sound, and yes, if you filtered the sound to remove overtones in the audible range then it would sound different. However, if you remove overtones outside the audible range then it will not make an audible difference (this is what xiphmont was saying in TFA).

So no, your wikipedia link is not a citation for the claim that cmer made.

Off topic, but I LOVE how every post on your blog has a different background image. Is there a theme for this or you did it custom?
IIRC, linearity is when you put a sound wave frequency into the medium (air) a some point, you can predict the frequency of the sound wave at some other place using a linear function - meaning that there is no distortion. Non-linear is when the physics of the medium starts screwing with that function.
Imagine the table-top tablet having a button to activate a voice connection to a remote call center, with a cheery, knowledgeable voice on the other end of the call. (I thought I'd read somewhere that some fast-food restaurants do this already for their drive-through windows.)

It could even be a video connection, with a small screen on the tablet, and one or more cameras to show all diners at the table.

The potential loss of privacy could be an issue for customers. The equipment to bug your dinner conversation would be sitting right there in front of you.
Agreed. These "assault course" style programmer interviews are getting more ridiculous - and seem nine-parts interviewer ego stroking to one-part ascertaining candidate quality.
Old computers, netbooks, arduinos. They are here for some time now and no miracle happened. Raspberry Pi might help eastern europe and africa but not UK.
"10-15 hours of my own time managing a server"

there is nothing at all about the 'recent things from apple' that prevents kids using them to make software, except for price

If all you own is an iPad, Apple don't let you run software tools on it.
Yes experimentation is great. but, many teenagers already have a laptop (or parents have their own). Surely there's lots of people with 2+ computers.
This is a valid point but at the same time - can every country make a lot of money selling extremely high end luxury goods? It seems to me (but I'm very open to information that would change this view) that Germany occupies a rather special position that doesn't scale out world-wide.

You are greatly underestimating the value of public libraries. Even if we agree that only a few motivated individuals actually used the libraries, that itself is enough justification for their establishment (IMO). For instance, Richard Feynman used the public libraries extensively, and he has been a source of motivation for many generations of physicists/ engineers (including myself). (Being from India, when I was younger, I really did feel the disappointment of not having access to a public library.)
I like the way you state this as incontrovertible proof + openly admit you are reading an overtly right-wing book. I wonder whether this is a troll...

All I shall say is a. I think you'll find it's more complicated than that, and b. look at the data.

There's a specific "bug" in the mp3 encoding scheme which means that you get a pre-echo effect on fast attack waveforms. It's inherent in the encoding, so it can't be eliminated (although the higher the bitrate, the less obvious it is IIRC). If you how know to listen out for it then you'll spot it immediately.

AAC / Ogg don't have that limitation & at high enough bitrate should be indistinguishable from the source in a blind listening test, as demonstrated in a number of Hydrogen Audio listening tests down the years, unless of course you're using crappy encoders at which point all bets are off...

(Really, LAME is very good indeed these days. I eventually decided that I was going to get with the program and just encode all my CDs (backed up to flac files) as mp3 for portable listening. It's good enough, and I've decided not to listen for the pre-echo artifacts so that I won't notice them :) )
The UK is weird when you start looking at "constitutional issues" (since it doesn't really have one). There are lots of "technicalities" which aren't true in practice. Like technically it has a state religion (Church of England), however it's quite secular as a country compared to many others. Technically the Queen has to approve and sign any law, but it's a rubber stamp, she can't refuse to sign an act. Technically Parliament can pass just about any law "that's not naturally impossible" (checks and balances? what's that?), but there are laws and other treaties, and the judges have some power etc.
I doubt this has anything to do with the "old class system", because you can see this pattern anywhere in Western culture.
O right. How did you determine that? To be honest I'm not a redditor. It's not a site that I visit, so I don't understand how it works.
Source? Do you have any actual evidence that say the ratio of profit per employee to average salaries is lower at banks than at engineering firms?

Simply paying more isn't the same as not being exploitative, even if it does make you feel better about yourself. I suppose it might make sense to consider the wider picture too, like how much of that increased income is produced by more fully exploiting other laborers.

I must admit I'm nauseated by the number of references to reddit on HN. I think reddit is powerful and fills a void, but the few times I've visited > cmnd+w. Twitter is also useful on occasion, but simply not my "cup of tea." These sites feel like eternal September, and make me consider suicide (not to over-dramatize...).
The Delilah Secure Speech System
---- I picked this:

3 While he was in Bethany, reclining at the table in the home of Simon the Leper, a woman came with an alabaster jar of very expensive perfume, made of pure nard. She broke the jar and poured the perfume on his head.

4 Some of those present were saying indignantly to one another, “Why this waste of perfume? 5 It could have been sold for more than a year’s wages[a]$30,000 and the money given to the poor.” And they rebuked her harshly.

---- I picked this:

9 He went on to tell the people this parable: “A man planted a vineyard, rented it to some farmers and went away for a long time. 10 At harvest time he sent a servant to the tenants so they would give him some of the fruit of the vineyard. But the tenants beat him and sent him away empty-handed. 11 He sent another servant, but that one also they beat and treated shamefully and sent away empty-handed. 12 He sent still a third, and they wounded him and threw him out.
13 “Then the owner of the vineyard said, ‘What shall I do? I will send my son, whom I love; perhaps they will respect him.’

14 “But when the tenants saw him, they talked the matter over. ‘This is the heir,’ they said. ‘Let’s kill him, and the inheritance will be ours.’ 15 So they threw him out of the vineyard and killed him.

“What then will the owner of the vineyard do to them? 16 He will come and kill those tenants and give the vineyard to others.”

When the people heard this, they said, “God forbid!”

---- I picked this:

25 At that time Jesus said, “I praise you, Father, Lord of heaven and earth, because you have hidden these things from the wise and learned, and revealed them to little children. 26 Yes, Father, for this is what you were pleased to do.
27 “All things have been committed to me by my Father. No one knows the Son except the Father, and no one knows the Father except the Son and those to whom the Son chooses to reveal him.

28 “Come to me, all you who are weary and burdened, and I will give you rest. 29 Take my yoke upon you and learn from me, for I am gentle and humble in heart, and you will find rest for your souls. 30 For my yoke is easy and my burden is light.”

----

What is "humble of head"? Now, you know "humble of heart".

---- God picked this:

12:21 And when Rehoboam was come to Jerusalem, he assembled all the
house of Judah, with the tribe of Benjamin, an hundred and fourscore
thousand chosen men, which were warriors, to fight against the house
of Israel, to bring the kingdom again to Rehoboam the son of Solomon.

12:22 But the word of God came unto Shemaiah the man of God, saying,
12:23 Speak unto Rehoboam, the son of Solomon, king of Judah, and unto
all the house of Judah and Benjamin, and to the remnant of the people,
saying, 12:24 Thus saith the LORD, Ye shall not go up, nor fight
against your brethren the children of Israel: return every man to his
house; for this thing is from me. They hearkened therefore to the word
of the LORD, and returned to depart, according to the word of the
LORD.
How do Wonga et al tie a borrower to his facebook/twitter/osm account? And then how do they get the data for an account?
There are two things: computer science and programming. you can learn one without being competent at the other.

Programming is programming. I don't care if it is just Javascript on a web page, or if it is C. The key is being able to step through the code and think through exactly what it is telling the computer to do.

When I started teaching my son to program we'd play games like "tell me how to get home from here," and I would pretend to follow his instructions to the letter, showing him how the exacting nature of computer instructions work. Every time he'd use a mistaken preposition we'd pretend we got stuck somewhere, or in the river or something. It was a lot of fun.

Computer science is different. Yes, it's helpful if you are in certain fields, but let's not confuse it with programming.
> can every country make a lot of money selling extremely high end luxury goods?

It seems to be working well for Apple...

In any case, the biggest car company in Germany is VW, and I wouldn't consider them a "luxury" car manufacturer. And most of the Mittelstand in Germany are companies that are not household names, but are very successful in their particular industrial niches.
A news site in Australia here seems to know when the tab is visible and auto plays the video content for a story. I assume it's using these Javascript events too.
Yeah there are lots but even the poorest can afford a RP, which is more and more is better.

Even the richest parents would think twice about allowing little alice to throw her laptop off the roof.

As a kid that grew up without a lot of stuff and my parents struggled to get me my first computer (Oric 16k). It changed my life. I think the RP will change more lives and open up more avenues to genuinely poor kids who want to experiment.

Great ideas are not just generated by middle/upper class kids, us working class kids have great ideas too.

I realise this is a great generalisation and we live in a 'class-less society' and money goes up as well as down and some kids will indeed use RP to record their sisters undressing and some kids will try and snort their RP up their nose BUT it's a genuine opportunity for ALL kids and I endorse it.
actually it's up to 3 (or at least it was)
The City (where managers are so well paid that they don't feel threatened) pay technical people fairly

Another reason why The City might pay higher: Since there is so much money at stake/to be made, and since it's so compeditive, and rewards can be gotten so quickly (you could make millions in one year, no need to wait for things to pay off) that it would be foolish for a upper class toff to sit on their hands and not hire the bright young commoner.

It could be that the traditionalist companies probably missed out on a lot of good techies, and hence weren't able to compete and were marginalised by companies who did hire based on merit, not class.

Capitalism at work for our labour.
I am not sure I understand what your problem is here. If negative karma accounts that have not been active for months are downgraded in some way - it just strikes me as sensible housekeeping.

Perhaps you can explain the issue as you see it?
It's simply not a full system analysis, > unity efficiency WRT input electrical energy. There's just a corresponding draw of energy from the environment that is also producing photons.

>"You can only convert the kinetic heat motion of a single molecule to kinetic energy in your target if your target is colder than the source! And there's your cold sink." //

This is counter logical. You're saying that a small fast moving body can't impart energy to a large slow moving body. Can you explain further how this works at the single molecule level?

I don't really understand your negativity. I agree it's impossible to help everyone. But what could be the possible downside to trying? Why is idealism a dirty word these days?

I mean it is the idealism that motivates him to do this in the first place, if it turns out the raspberry pi motivates a few kids to become great engineers/inventors/scientists, that's great right? Would it have been better if he was cynical about it?
Yep, reminds me of a great quote: "If you're having trouble hiring, you are by definition offering below market rates".
> This is quite true in India; a lot of the infrastructure laid down by the British is still in use

I think that says more about India than it does about British engineering.
as soon as you ask me to spend a week--even a day--on some audition project, forget it.

Note that he proposes the audition project to be "a regular consulting gig with an hourly rate", spent on-site doing real work.

You don't have time to earn money doing real work? Then why are you applying?

And even for a "truly good" professional who has his pick of a dozen offers, I could see this as a good idea, since they have just as much reason to be interested in the company's "real" work environment than the company has to be interested in their "real" work performance.

That's pretty obvious. But please try to understand it before assuming there is no problem.

PS. I just realized why you think they are not active! You don't have showdead turned on in your profile, so their dead posts are hidden to you.
Which means that either

1) The free market is not efficient

2) There is some hidden benefit to overpaying clueless PHBs

I'm genuinely curious about this, actually...
Indian railways is one of the third largest employers in the world (the Chinese Army and the UK National Health Service are the other two) and yet they are well known for being bloody awful.

EDIT: Forgot to add:

The engineering might be good, but the middle management was often really poor and the build quality of mass-produced items was usually sub-optimal.

Combined with post-war poverty here and post-war subsidies there (Japan) the UK had a weird combination of factors.
I personally don't associated Germany with luxury goods (not in the same way as Italy or Switzerland) but I do associated it with very high quality engineering.
I think to a certain extent 3 or 4 years ago Reddit was very much like HN is now. When I first joined Reddit (2007) there was generally a lot of reasoned discussion, and the submissions were very much programmer orientated in a way that's long since passed.

I'd imagine (although I suppose I have no real evidence for this) that the people who talk about Reddit and HN in the same context were active on Reddit a few years ago.
My only real qualm with this is whether to bill them my consulting rate or to put up with something well below the salary I would expect for ongoing stuff.

But if it's short and interesting, it usually falls into "I don't care" and stays there.

I'm agreed on the week of work, since as you say, no one in a proper job is going to take a week of holiday to come and work for someone who may or may not employ them.

Probation however is a standard clause on every UK employment contract I've seen, usually with a 3-6 month period, during which either side can get out without penalty if it isn't working out.
Solution to getKeyCode() returns 0 in Java
Okay, to get this out of the way first: I completely agree with Jeff that hiring programmers is hard and that the way a lot of companies go about doing it is about as effective as Russian Roulette. I've seen it and felt some of the dismal consequences. As a matter of fact, I still have to work with lots of those people that should have been filtered out in step 1. So yeah, I agree with the idea.

Having said that, his process, taken together, is ridiculously one-sided. The message it sends comes across as "Of course you want to work for us, regardless of all the hassle we're putting you through, who wouldn't? Only someone out of their mind, that's who! And we don't want people like that here."

Think about it, Jeff. You are asking for someone who:

1) is highly skilled

2) has an attractive portfolio

3) is mature enough to communicate well

A lot of people like that already have jobs. If you want them to do #5 -- which might be something they're forbidden by their current employment contract, by the way -- and you also want them to prepare a presentation for #6, you must be the sexiest employer on the Earth.

In short, what do you propose to balance things out?

In terms of suggestions: I'd be cool to see if we could make that a regular meet-up, e.g. every month.

For the first event, I'd recommend not to have any planned talks/presentation but to try it out and to see if we there'd be enough people to meet regularily.
You don't have time to earn money doing real work? Then why are you applying?

False dichotomy. I'm already earning money doing real work. I'm not applying so that you can cut into my family time. I'm applying because I want work that's more interesting or more money or who knows what. If you really want to know, ask, instead of assuming ;)

EDIT: Clarifying the "more interesting work" expression.
Just be polite. That's all they ask.
