Although the density of interstellar matter is very low, as the spaceship accelerates, the apparent density increases drastically. Compare this to a descending orbital craft that encounters immense atmospheric resistance, while an airplane easily survives sea-level flight at much lower speed. Thus, it really does make sense to build aerodynamic spaceships.
How do you get losetup to accept -e blowfish? Mine only takes xor and des (and none). If you look at lomount.c in unix-utils-2.11r, you will discover that those are indeed the only options it supports. Examination of the password input switch statement suggests that each different encryption type requires a different passphrase format (is that true?). So how do I get it to support more formats?
Would you mind writing a HOWTO on how you did that? I am sure lots of people want to know. Cryptoloop is seemingly impossible to get working on my RH8. Some hack to lomount seems to be necessary.

Yes, the should. But the solution is not to retain backward compatibility for undocumented APIs, but to not expose them in the first place. Then the programmers will tell them what they need and there will finally be a documented API out there. Otherwise you get software that stops working for undocumented reasons. Ever try TIOCL_GETSHIFTSTATE?
Although it is quite popular with hackers, the "works for me" answer simply doesn't solve anybody's problems. The author of the article is referring to third-party applications (mentioning QuickKeys addon specifically), which stopped working. That most likely happened because it was using some undocumented API that got removed.
Linux cryptoloop requires you to separately mount the directory. Because you can only do that after you log in, the home directory itself can not be encrypted. Furthermore, you have to type in (and remember) another password, which is a major hassle. And read a bunch of HOWTOs before anything works. And recompile the kernel, since Crypto API is not defaulted in most people's kernels, if it is there at all. And you may need new version of lomount because the one you have probably only supports DES. And...

I don't know about your keyboard, but mine generates different scancodes for left and right alts. Only the left alt triggers a ctrl-alt-del event to init. The right alt does nothing unless you mess with your keyboard map.
Would someone who has 100,000 files please provide us with examples of what kind of files they are? I simply cannot imagine why anyone would have such a great number. Without examples it is nearly impossible to imagine any use for such a filesystem.

You could say the same about drug dealers, loan sharks, casinos, contract killers, etc. Who is the government to "kill off" their "entire industry because that industry bothers some people"? Who indeed...
It's the Russian mentality. Do you know why Russian planes don't get hijacked? They used to be, until the hijackers found out that the threatened pilot simply dropped the controls and started fighting back. No wimps in that country.
On all those screenshots there are many "holes" in the words, as if the layout engine had trouble figuring out glyph sizes. What is that caused by? Did they get signs wrong in the kerning tables or something?
First of all, OpenOffice does not compile on my machine. I get screenfuls of compile errors and it stops. Sure, real programmers debug everything, but did you look at that ugly code? The directory tree goes a dozen levels deep, there is no obvious logical separation of components, and heaven forbid you ever try to figure out where some data structure is defined. Report it as a bug? Ppplease... They'll just mark it off as non-reproducible (after all, I assume it compiles fine on their machines.), blame my compiler or tell me I'm not setting some environment variable right (something like the latter is probably the case). In a cleaner project it might be worth debugging some and sending a patch, since you can understand the code; OpenOffice code is beyond understanding. And when a regular user wants to install a package like this they would not even try compiling it themselves just for such reasons.
It's slow enough on my dual-proc 1000MHz athlon board with 512M RAM. I can not begin to imagine how much patience you would need to run it on a 90MHz pentium.
You forgot the bullets...

The article mentions an interesting fact that the researchers are using bullets instead of sound shock waves. "That will, of course, destroy the crystal"... I can just imagine what goes on in that lab:
"Allrighty, George, it's your turn with the gun."
"But Bill, you know George can't hit the broad side of a barn!"
"Nonsense, my dear fellow. We need to produce some blue light soon, and that calls for a once-in-a-blue-moon event. Come on, George; ready... aim... fire! Take the safety off first, George. Gees... you call yourself a scientist? Ready... aim... fire!"
It is trivial to add runtime bounds checking to a C++ class by putting an assert into the operator[] implementation. If you feel you need more information, you can actually throw an exception (possibly inside a #ifndef NDEBUG) and fill it with the crash context as you unwind the stack. Java did not invent exception handling. As for your problems with memory management, they result from a failure to adhere to the cardinal rule of memory allocation: delete allocated memory in the same scope where you allocated it. That's what Java enforces for you. Memory allocation is easy if you know exactly who owns each block, and if you ensure that this ownership is consistent and preferrably non-transferrable. Any memory management nightmare you encounter is always the error of a programmer who does not know who owns his objects; and there is absolutely no excuse for such irresponsible behaviour.
You can reference array elements that do not exist in Java too, and in any other language. The only difference is that Java will throw an exception, while a C program will crash. As far as the user is concerned, the result is identical - bye bye data.
That's just the point. You stop manufacturing parts in English units and as soon as you run out of those parts, the old products become obsolete. There will always be mechanics who will rethread a bolt for your vintage car, but most people will soon only need metric parts. So recycle the old bolts.

If you want it to last, type it up!
A pencil is the ultimate space pen. It writes because the graphite flakes off and sticks to paper, which will happen in a vacuum as well as at 1 bar.
Would you mind writing a HOWTO on how you did that? I am sure lots of people want to know. Cryptoloop is seemingly impossible to get working on my RH8. Some hack to lomount seems to be necessary.

So are you sending this from the doghouse?
By infinite recursion due to a short attention span?
I'm sorry, ET; I'm afraid we can't allow you to send that signal... Microsoft, you know...

Now make replace the glass tube with a buckyball and put three benzene rings in as the electrodes. Voila! A nanotech transistor.
I don't know why people are excited by fast cars. If you are not fast enough to orbit, you are too slow!
