I'm convinced you'll observe the same if you try to teach a class Chinese, yet in China, everyone manages to learn it just fine. Start early and practice every day works for almost any skill.

I'm not convinced you can learn a language in school. I had to study 4 languages in high school (one of the many down sides to growing up a native speaker of a dying minority language). For years, never mind semesters. I always had decent grades for them too. Two of them are now missing. If you don't get to use a language every day, it just goes away, no matter how hard you studied it in school. I would have been better off taking crash course a month before, if I ever end up needing one of those languages. Or another.

I don't agree that one needs some special innate ability to learn to write code that most people just don't have. Anyone who can learn how to read and write, and is capable of following a recipe for baking a cake, is capable of learning how to understand and write a simple program. Writing instructions in English is not a fundamentally different thing from writing instructions in your favorite programming language. If you do it every day, in an environment where you get feedback from peers, and care enough to learn best practices, most people would probably be able to learn to do it well enough to get paid for doing it. Mind you, I'm not saying everyone has what it takes to be a great computer scientist. This is about programming.

Question is: should you make them? There are already so many required subjects, and this is yet another one that most people wouldn't have any use for throughout their entire lives. Almost everything learned would just fade away within a few years after graduation, leaving nothing but a bad memory of spending endless frustrating hours learning something you couldn't care less about and would never need in your life.

I think a good school should probably offer computer classes for those who are interested. I just don't see the benefit to forcing it down people's throats

You're assuming USA, where a 6 figure salary is something you expect either straight out of college or after a few years at most.

In the rest of the world, this isn't necessarily the case.

And you don't have all the answers either

The 'rock' in question is a microscopic zircon crystal, not an actual chunk of rock. Think of it as a very hard grain of sand, that has been weathered off the rock in which it formed, deposited somewhere as sediment, which turned into sedimentary rock, and so on, perhaps a great many times, before it settled in the rock in which it was found.

The Himalayas started uplifting some 50 million years ago, but that doesn't mean the material in it can be no more than 50 million years old. The rocks weren't melted in the process. Who knows, perhaps there is a grain of zircon embedded in a chunk of sandstone in the Himalayas that's even older. Perhaps a geologist can explain why this is or isn't possible, but it would definitely be like searching for a needle in a haystack.

The reason for searching in places like Australia, is because exceedingly ancient rock formations are exposed there, significantly reducing the size of the haystack.

The iron formations are about 2 billion years younger.

The banded iron formations were formed by the earliest photosynthetic life, between 2.5 and 1 billion years ago. Oxygen produced by these single celled organisms formed iron oxide with dissolved iron ions in the oceans and precipitate on the ocean floor. This started when significant amounts of oxygen started dissolving in the water, and ended when most of the iron was used up. When that happened, the oxygen levels of the water suddenly increased, killing nearly all anaerobic life on earth, and opening the door for our aerobic ancestors.

The front page is a definite improvement. It looks cleaner, more modern.

The new comments section could use some work. Why do comments have different fonts and sizes? The biggest problem with the comments isn't the site though, it's the content ;)

What alien race wouldn't want to get in touch with a species that likes to blow up stars?

Never mind just 'today'. I vaguely recall someone publishing a proof that beyond a certain disappointingly small radius, any RF signal originating from earth is mathematically impossible to distinguish from background noise.

I don't know about gas tight, but without flowing water or ice, and without plate tectonics, the Martian surface doesn't move around much.

Code and forget for 3-4 decades? No, 30 year old mainframes are no longer of any use to anyone, and code than hasn't been touched in 30 years probably won't work anymore. The idea that there are still dinosaur mainframes and cobol code from the 70s chugging along somewhere is a complete myth. IBM still regularly releases new models of mainframes, and old ones are deprecated. You regularly get new releases of OS/360 or whatever it is called this decade, and if you're too many releases behind, you lose support. Cobol applications are still being maintained, developed, and upgraded regularly, and new projects are still made in cobol. You may not like it, and it may make you a little sick, perhaps like the idea that your parents are still having sex, but that's the way it is.

I can also tell you from experience that any non trivial Java code not touched since the 90's probably won't work today.

You didn't read the article. No one did. According to the article, a custom built windows PC with equivalent parts costs about 10% more than the mac pro.

He probably didn't get the best deals, but the days of a 100% surcharge just for the apple logo are long past. Equivalent Android and iOS devices seem to cost about the same, and ultra books seem to cost more than the equivalent MacBooks.

I'd be very interested to hear about a billions upon billions of transactions per second system based on any technology :)

We make a SaaS application. Every major release comes with a change log. Not the raw, unedited and complete change log TFA talks about, but a human readable, edited one of the form
- feature we promised
- change you asked for
- other change you asked for
- new surprise feature
- UI improvement foo

and finally....
- numerous bug fixes

Bugfix releases don't have a separate published change log. Instead, customers who reported a bug are notified directly when it has been fixed.

This way it is useful for the customer. What the customer really wants to know is that they're not paying you for drinking coffee. They don't want information overload. A complete change log would only make sense to people who work with the code.

IT job ads are very specific because the kind of job makes it possible.

When a recruiter is looking for candidates for a hi-school music teacher, exactly what specific skills and certifications could they list? Must have at least 3 years of experience playing Beethoven's Piano Sonata No. 14 in C-sharp minor on a August Forster UP 114 piano?

This sounds like good advice, but really isn't

If you apply for a visa to the US for a visit that doesn't require one, you are acting suspiciously! The request will likely be denied for the simple fact that it is suspicious, and here's the kicker: if you have been denied a visa once, it becomes very difficult to enter the US. You can never make use of the visa waiver program again, and having previously been denied a visa may be grounds for rejection the next time you apply for a visa.

A better advice: just do exactly what is required.
