There isn't any "extra hour". The duration of daylight is independent of what your clock says. If you want people to start work earlier in the morning in the summer, then lobby businesses to shift their working day. But futzing with everybody's clocks in the US accomplishes absolutely nothing apart from annoying those of us who have to communicate with people in other countries. Which, nowadays, is more and more of us. Time, in a fixed location, should increase monotonically. It shouldn't go from 01:00 to 01:59 and then back to 01:00 again. It beats me that any sane person would want this.

It's 1989 in my alternate universe. I predict that before the end of the 20th century, grading answers on coding tests will be completely automated. The answer will simply be executed on a computer for a variety of inputs, and if a student's solution gives correct answers and executes in a time not too much more than the execution time of a reference solution, the student gets credit for a correct answer. (The exact grade could depend on the execution time, if you want to get fancy.)

I thought that PNG was a "next gen replacement" for GIF about 20 years ago?

No, it's not easy. The worldwide free-software development community needs to have hosting that serves the whole community, regardless of any one government's whims, but providing it is going to be difficult. The US government is powerful and wealthy and it will try to sabotage or cripple any globally-free hosting, by for example DDoS attacks, and it will also try to cut off its funding, as it did to Wikileaks.

The United States government really does care about BTC and has a strong interest in killing it, because BTC enables international money transfers outside the banking network. The United States government enjoys de facto control over the interbank network, which it uses to bully countries which it doesn't like (for example, you can't transfer money to a bank in Iran). It is therefore entirely plausible that the current DDOS attack on BTC is mounted by agencies of the US government. It has the motive, it has the means. In the absence of evidence about the identity of the attacker, the US government is the #1 suspect.

I'll prove it to you right here, right now.

1: Procedure to use Windows
Go into computer store, buy computer, take it home, turn it on. Wait for it to boot.You are now using Windows.

2: Procedure to use Linux
Go into computer store, buy computer, take it home, turn it on. Find out where to download a Linux distro from. Download enough to do network install. Burn it on a CD. Boot from the CD. Select installation options ...

And yes, I do realise that isn't what you meant, but the proof it still valid, and explains why Windows has approximately 100 times as many users as GNU/Linux on the desktop, and will have for the foreseeable future.

Neither the post, nor the article linked, tell us much. "Open Source" just says that some people can read the source code. It doesn't tell us:

1. Who can read the source (licensees only?)
2. What you're allowed to do with the source

"Open source" doesn't mean "public domain". Somebody still owns the copyright, and can make permission to copy the source conditional on acceptance of a license. Then the terms of that license are all-important.
