Now, now, now, it's not the version control system's fault that you checked in a bug....

As for IT costs - I have worked in several companies over the years with both UNIX and Windows server rooms. Being a UNIX person, I may be a bit biased, but my personal impression is that supporting Windows servers is a lot more painfil than supporting UNIX/Linux - at one point I supported some 50 UNIXes alone, while the roughly similar number of Windows systems had a team of 5; I had a pretty relaxed daily routine, but they were always overstretched. Not because they incompetent, I learned a lot of generally useful stuff from them, but so many things in Windows seem to require either clicking through graphical interfaces, system by system, or require a specialised, graphical tool, where I would just run a few scripts from a command line. The power of tools like ksh (or bash), ssh, sed, grep, find etc should not be underestimated.

The other thing I have heard increasingly - from Windows admins themselves - is that Windows is just such nightmare to handle. I wouldn't know - I left Windows behind as soon as Linux became viable, and that's a long time ago.

I got the same error after a glitch. Turns out the redemption was successful the first time, but because the server was too slow responding to the redemption request, the App Store app timed out. For whatever bizarre reason, it appears that the app store server infrastructure doesn't treat redemption requests as idempotent (clearly a bug), so subsequent attempts to redeem the same code from the same account fail. Ideally, those subsequent attempts should do nothing, but should return whatever magic value tells the App Store app to update its list of purchased items and then do whatever other work it needs to do.

To make a long story short, if you quit the App Store app and relaunch it, the Yosemite beta should appear under the Purchases tab in the App Store. From there, you can start the download.

A nonprofit competitor is required by law to spend any profits they make on upgrading infrastructure. So unless they massively overhire or have higher expenses because of economies of scale or renting a more expensive building, the nonprofit is pretty much guaranteed to be able to undercut any for-profit competitor while providing better service, because it doesn't have the extra overhead of profit taking.

Particularly if all you need is heat. You could potentially build an almost entirely passive desalinization plant fairly readily by building a greenhouse atop the ocean and making the roof slope towards the sides with catch basins that then flow downhill towards the shore. The only thing required is an insane amount of glass (and an insane amount of space to dedicate to it).

Rum, of course. Or, if you prefer, vodka.

Of course CERN had problems - this is not engineering, but science. The big difference between the two being that you call it engineering, when you know in advance how to do, and science when you don't. No doubt, the first time a simple van-der-Graf accellerator was built, they had to overcome a number of problems; now, it is something you'd let a student do, because all the technical problems have been ironed out. And when/if China builds this new cyclotron, they will run into a large number of technical problems; of course they will. No need to start constructing fables about "all the corruption"; all that says is that you are suffering from petty envy.

Being aggressive is always the first response a man comes up with when he feels insecure or under pressure. However, speaking as a man - that is, an adult, experienced man, not a not-quite-out-of-puberty boy - I think it is always wise to listen to criticism and try to understand it. Objectively, it does not harm you or make you vulnerable, if you are open to criticism; quite the opposite, in fact. If you are doing something wrong, then criticism is your chance to improve yourself and become better, and if the criticism is incorrect, then you can reject it, so no problem.

And I disagree with your comment about 'nice ass' - unless you are complimenting somebody's donkey, this counts as an uninvited, sexual advance. Assuming that you are male and the only heterosexual in the office, just imagine receiving this sort of comment from just about every gay man around you. Even if you are not homophobic, would you like it? Probably not. This is about respect - you earn respect by showing respect, and you gain self-respect by earning respect from others.

In theory, you can always learn more by continuing to study something. In practice, though, modern medicine has a pretty complete knowledge of smallpox. Humans have been studying the disease since before anyone even knew what a virus was. There's evidence that the Chinese were inoculating people for smallpox over a thousand years ago. And the first practical, widespread form of that vaccine dates back to the late 1700s. This was literally the very first virus ever treated with a vaccine. It's well-trodden ground, research-wise.

The problem is, this virus is highly contagious and relatively dangerous compared with other viruses. For variola major, the case fatality rate is typically 30–60%, which puts it among the worst communicable diseases out there, approaching the fatality rate of ebola, and far more contagious. With nearly a two-week average incubation period (and up to 17 days in the worst case), one minor screw-up could easily cause a very serious pandemic before enough vaccines could be produced and distributed.

So basically, you have to weigh the odds of an accidental release (which, with recent revelations about this stuff getting lost for decades, then turning up by accident, seems not so improbable) against the relatively small chance of learning anything new from it that can't also be learned from cowpox or other similar viruses. On the risk-reward curve, this seems to be so far towards the "pure risk" end that any reward would border on undeniable proof of divine intervention, which means the speculated rewards would have to be pretty darn amazing for it to be worth the risk.
