Even complete failured it trained of equipment is trained for. The military is taught not to rely on equipment to get the job done. Multiple failures are expected, and can easily happen in any combat situation.

Multiple failures can easily happen in any upgrade situation.

I was with a unit that was heavily into the computer based operations, and one upgrade cycle was particularly frakked. Networking was almost nothing but timeouts, apps wouldn't start, etc. Eventually, I gave the system layout a glance to see if there was something obvious. Among the many things I found in about 10 seconds of looking, was something like:

$ ls -l

---------- 1 root wheel 69 May 5 20xx /etc/resolv.conf

There were far more heinous things done to all the machines on that LAN. And even with all that, we still figured out within the first day how to get our jobs done. Not quickly, and not without a lot of hassle, but we still got it done. A fairly complete fix took a few weeks though.

And they wonder why sailors drink.

There are four types of meteor composition; roughly ice, carbon, stone, iron. These types notably differ in how deep they can get into the atmosphere before they shatter (explode), with shatter altitude varying mostly by size. Iron meteors generally get all the way to the surface intact. And any part that hits the ground counts as a meteorite.

Given how many other than alpha-numeric characters there are in the languages I use, I'm not sure I could describe more than a trivial script in an interview. And even that would sound like, well, I'm not sure what it sounds like to HR types; they always get this otherwise glazed expression with their eyes replaced by black voids.

The standard /. car analogy is I bought a car based on the advertising assumption that I could drive it any time I want 24x365. I'd be pretty pissed if I found my garage empty one day and it turns out they've been renting it out to 3rd parties behind my back, after all most customers don't use their cars 24x365 and its industry standard in the crooked fine print to profit off renting customer's cars to 3rd parties, etc etc.

Only 24x365? Well then, yeah, I'd kind of expect them to pull that renting out to 3rd parties on February 29.

Comment Re:But for Terraforming? (Score 1) 264

They both have terraforming potential; just different problems to overcome. Over the relatively short term, Mars looks closer to falling within what technology and industry may be able to handle.

Venus has a very weak magnetic field induced by the solar wind interacting with its atmosphere (which strips lighter elements like hydrogen in the process). It has no intrinsic magnetic field. Mars has regional magnetic fields locked into segments of its crust left over from when it did have an intrinsic field. Either way, a magnetic field isn't necessary to block solar radiation; a fairly thick atmosphere with an ozone layer has that covered. Before Earth developed an ozone layer it looks like land got too much UV for much of anything to handle, but the oceans were okay.

For long term atmospheric stability over multiple billions of years, a planetary mass object should have at least 20% of Earth's mass, although it may take 30% to be fully stable. Mars, at 10.7% could hold an Earth like atmosphere for a "mere" hundreds of millions of years. Note that hundreds of millions of years is comparable to the Phanerozoic Eon which covers the entire existence of multi-cellular animals, and is also comparable to the expected time before Earth unavoidably goes into a runaway greenhouse effect.

You still have to get several exagrams (Eg) of atmospheric materials from somewhere though, and maintain a much smaller replenishment program if you want Mars to stay habitable for more that several hundred million years.

To precipitate out Venus' atmosphere, you'd need a few hundred zettagrams (Zg) of calcium and/or magnesium to react with the carbon dioxide to form calcium carbonates and/or magnesium carbonates. You'd also need around a hundred or so Zg of hydrogen as Venus is almost completely lacking in that. Any biological processing has no chance of going anywhere without the hydrogen. The solar wind will, of course, slowly strip hydrogen away, so you'd need to maintain a replenishment program for that, too. And then there's that pesky runaway greenhouse forcing from being that close to the sun.

So, in short, terraforming Venus looks to require ~100,000 times as much material as Mars, but can get potentially be made much more similar to Earth.

All the OSs I've run into the the most recent few years fully support UDF. And FUSE (if installed) seems to almost require ZFS be installed as well.

A quick check of flash media locally turns up nothing but UDF. If including optical media, it's split between UDF and ISO-9660. So what doesn't support UDF these days?
