I certainly DO mean "earn more money". Flash-in-the-pan "language of the week" programming jobs get you a lot of money for a little while but it's not a legitimate career plan.
Learn how to read, learn how to write clearly, learn fundamental knowledge, and you aren't stuck looking for narrowly-focused programming jobs.
I know why you are asking these questions, but I think you are missing an important point. You are looking at college like a vocational school - not a chance for a rounded education. You will do FAR better in the long run if you learn fundamental knowledge in many areas, and not spend a significant amount of time on specific training.
Once again, every time this topic comes up, the answer is always *paper ballots*. I feel compelled to point out that the entire reason there are electronic voting machines throughout the USA is because *we had a big problem with paper ballots in Florida*. The problems with paper ballots are almost the sole reason electronic voting is being persued. It's clearly *not* transparent and *not* straightforward - there are STILL people going over the ballots trying to get a different result and people are STILL arguing about "hanging chads" and stuff like that. Not to mention the numerous election "irregularities" that happened and continue to happen with paper ballots over history.
The points about electronic voting are largely valid (the technical points, not the conspiracy drivel) but the theory that paper ballots represent some sort of perfect world are just foolish and fly in the face of the numerous demonstrated problems
Uh, what? There was no established digital standard when ATSC development started. The only existing standard was the Japanese standard and that was analog - which still seems like a completely crazy idea.
You are technically correct that hydrogen (or anything else) has to have an oxidizer (air) to burn. One of the biggest problems with hydrogen, and what makes it much much worse for flammability as a gas, is that the allowable range of fuel/air mixtures is the highest for any fuel. Hydrogen can burn with anywhere from about 4% to 75% air included. Compare that to gasoline vapor , also very dangerous (TWA 800 disaster) has flammability limits of something like 1.5 to 8%. What that means, from a practical standpoint, is that there's no practical way to keep the hydrogen in a non-combustible state. Some air will always be in there, and some hydrogen will always be in there (once it's been loaded the first time) so you have only one safety plan - complete avoidance of any source of ignition. That, too, is practically impossible as well. If you have plastic on board, you have an ignition source.

I read TFA, and these guys seem to be worried about the wrong thing. Word menus, etc, are easy enough to deal with. What makes it a god-forsaken piece of shit are all the bugs. Documents are always getting corrupted, figures don't do where you want and stay there, can't save sometimes for no apparent reason, the entire thing just bombs out, etc. We had a "Platinum Support Ticket" or some similar nonsense open on Word for a few years. The upshot, direct from a Microsoft senior support line, was that if we wanted documents to not get corrupted, was to print it out on paper, make sure it was right, then use a scanner and save it as a TIFF. Thanks, that's good advice.
What is so pathetic is that I have ordinary technical documents from the late 50's and 60's that are laid out better, have better graphics, and are still perfectly readable today. While at the same time, a Word document I saved last week either can't be opened, or has all the symbols corrupted.
About every 10 years or so, someone proclaims the return of the airship. The problems with airships are the same they have always been - high susceptibility to winds and difficult ground handling. Those problems are essentially insoluble - it's *lighter than air*. The combination helicopter/blimp had been tried at least half a dozen times, all unsuccessfully.
The hydrogen/helium thing not an issue. It's not going to use hydrogen. Whether that's what got the Hindenberg, or not, flying around with tens of thousands of cubic feet of exceptionally flammable gas, with a HUGE range of fuel/air ratios at which it can sustain ignition, isn't going to happen. It's a *bad idea* and wouldn't pass the laugh test for FAA certification.
In the same sense that the Pythagorean Theorem is a theory, not a fact. In other words, Nyquist's theorem is indeed a fact and mathematically provable, and proven. If you are, subjectively, hearing something that suggests it is not true, you are hearing *some other problem* and attributing it to this.
There is an advantage to higher sampling rates, but it has nothing to do with the frequency content of the recorded material or Nyquist's theory . If you sample at 44.1 khz (CD standard) you get 44.1 khz noise in the output. That has to be filtered out somehow, without affecting the in-band audio signal. Rolling off many DB in a short frequency span (factor of ~2) takes quite a filter, which depending on how it's done, introduces phase shifts of the in-band signal. The sound quality from CD players it largely determined by how, and how well, the D-A conversion (which has a frequency response all it's own determined by the guts of the converter)and analog filtering are done.
Sampling at higher frequencies makes it easier to build a good output filter. That's a very secondary or tertiary level effect, so it doesn't really make much difference, but it theoretically could.
Note that this is assuming the standard PCM encoding. "Single Bit"/streaming encoding (like SACD runs at fantastically higher sample frequencies, but the frequencies aren't really comparable (and it's not a good way to go because you introduce other issues (like tons of quantization noise).
The only identified issue with the standard red-book CD format is the dynamic range, but there are so few sources that need more than 16 bits and certainly very few playback systems/environments that will let you take advantage of it, it's essentially a non-issue. HDCD (which is a 20-bit PCM format) addresses this but hasn't and probably won't become common.
Bottom line - the guys who came up with the audio CD sampling format pretty well knew what they were doing and there aren't any practical limitations in the recording format. Everything else in the system (from microphone to engineering to speaker) is the limiting factor.
Because that plan would involve FAR more weight than any proposed air-bag system. To "stop" at the ISS would require that a large amount of braking fuel be carried all the way to the Moon and back just to reduce the velocity to Earth Orbital velocity. As opposed to letting friction slow you down.
There is some potential value in an Earth orbit "stop" on the way out (as was one of the baseline plans for Apollo, early on) but definitely not on the way back, if you can build a thermal protection system to take the full-speed reentry. Which we can, easily.
Oh, good lord. What Energiya would that be? The prototypes corroding away somewhere, never having been launched? There is no such thing as an Energiya, aside from old photos with a Buran attached, and some blueprints. You'd do better to start from scratch than with Energiya plans.
And of course, you overlook the many domestic alternatives that *actually exist*. Like EELVs (Delta and Atlas). Or those that could be restarted since they just quite making them a few years ago (Titan IV - roughly equivalent to a Saturn 1B).
That's about the max for the SR-71. In operational use, they were limited to around Mach 2.8. The highest speed recorded for any of the A-12 family was ~mach 3.56, in an A-12.
The fact is that, at the time, 4.4 meg was PLENTY enough for almost any purpose. It's a sad fact that modern software/data file type bloat has kept pace or exceeded the ability to provide storage. Doing the same job today *demands* gigantic HDs. For that matter then computer it was attached to would have been embarrasingly slow by modern standards, but it too was more than sufficient for the task.
No one can hack into a classified (Secret or above) network from the outside by sending them emails or anything else - *because classified networks are not connected to the outside world*.
$350 sent to sub-Saharan Africa would wind up in the hands of a warlord who would then buy another AK-47 with which to kill a family sometime in the next 3 years.
Except it doesn't appear to be a correct analysis. I can easily see the difference in the lighting and composition, but there still appears to be an extra/moved crater in the Chinese photo.

There are frequently many bugs in the microcode and other internal processor units, and they are typically listed. I have a list of one-line descriptions of bugs in the Teledyne 1750A processor that covers about 3 pages total. Most are minor, some required workarounds depending on your application. It's not uncommon at all, you just have to know about it and plan accordingly. They almost all are qualitatively similar to this bug. Maybe it's a bigger problem than some but its not unusual in nature.
