Typing an 11 x 11 (or larger) Matrix
How to use more than 10 tab stops in bmatrix or other amsmath matrix environments?
String answer1 = "yes"; if (answer1 == "yes") gives false. Why? Ok. So I read books as a kid, this may have been mid to late 1980s. Definitely before 1993. These details I remember, they might be from the same book or from several:   Slower than light space travel with severe time dilation. There were boardings of space ships, but the fighting odds could be very uneven because a foe could be from your future or your past, depending on when you started your space journey, because of relativistic time dilation. No faster than light travel, no time travel either. Just regular physics. To fight better in melee, soldiers would have (more or less willingly, I think they knew beforehand) false memories or notions implanted of the enemy as horrible human beings so soldiers could kill them more easily without remorse. Towards the end of the story, veterans of the war are described as not quite feeling at home after the war. One planet (home?) or country is described as inhabited entirely of clones, Adams and Eves, I think homosexual, or that sexuality could be switched deliberately. I think the veterans find at the end a refuge somewhere more like the home they are used to. The reason so much has changed is of course the time dilation. They spent maybe decades in the war, while on the planets centuries or millenia passed. I think one moral (there may be many more I missed as a child) of the story was the futility of war. If I recall correctly, the war was resolved in a way that made the efforts of the veterans seem for nothing. Does Qt have a C interface? Variables losing their values What is the correct way to completely remove an application? I've searched the net for such information and found different command lines, like these ones:  sudo apt-get remove application sudo apt-get remove application*  sudo apt-get remove --purge application sudo apt-get remove --purge application*  sudo apt-get purge application sudo apt-get purge application*   So, what is the correct way? Is it necessary to use that "*"?  After that, I also found these commands:  sudo updatedb sudo locate application sudo rm -rf (file/folder name) How do I make Units efficiently? I just blew almost all my money on a really cool lookin' ship. How do I regain solvency without spending a lot of time fiddling around in my inventory?  At the moment I've found a sequence of steps that'll turn 50 carbon and 100 Plutonium into ~5000 Units (by creating Suspension Fluid and then turning it into Electron Vapor). Are there better recipes or sequences of recipes I should look for? Or should I just drop the whole thing and go mine a particular mineral?

Light is clearly affected by gravity, just think about a black hole, but light supposedly has no mass and gravity only affects objects with mass.  On the other hand, if light does have mass then doesn't mass become infinitely larger the closer to the speed of light an object travels. So this would result in light have an infinite mass which is impossible.  Any explanations?

EDIT : How about a forced comment   dialog...which forces the user's to   comment when they downvote otherwise   they can't....right now it just shows   a popup to suggest posting a   comment...maybe this is little too   strict...but i just find it annoying   when ppl downvote and leave no   comments....   How about having a badge "Irritable" for a user who downvotes over 20 times in a month and then have maybe further "Furious" for over 50 downvotes in a month....just a fun suggestion...since i see people downvote like crazy at times...there should also be a way to downvote a comment i think in addition...

IOS 5.1.1 Safemode problem I jailbroke my old iPod Touch 3rd Generation, with IOS 5.1.1, using the latest version of absynthe. It worked for several months, but then it randomly stopped. It went into safe mode, but the touch screen wouldn't work. It showed the lockscreen, but nothing worked at all, except for the physical buttons. The only way to reboot is to follow the same steps as DFU mode (Hold power button 3 sec, then home button AND power for 10, then just home for 8)... However, it always boots right back into Safe mode.  I had to restore, and once rejailbroken, it worked fine, until I installed SBsettings. Then it did the EXACT same thing, and I had to restore and re-jailbreak AGAIN! The other day, I finished installing ALL of my extensive list of tweaks, and got it to about where I wanted it, when lo and behold, it booted to safe mode again. I have spent so much time on this, and I do not want to do it again. Does anybody here have any knowledge on the topic? Is there a program I can run from my computer to manually control the device or kick it out of safe mode? Is there some other method of doing this? I am looking for any solution OTHER than restoring. I have done that several times.  Also, I know the problem isn't with my jailbreak. It worked for several months before, then one day stopped. Now, it has the problem within a day of rejailbreaking, OR instantly if I install SBsettings. I re-installed the jailbreak, and applied the new one as well, and that didn't work. I have given up, and don't want to go through the painful process of restoring, rejailbreaking, and re-installing all of those tweaks again.  Also, because I can't get into my iPod, I can't provide a list of tweaks. I would if I could, but it just can't happen unless I can get in there. What's the easiest way to run GUI apps on Windows Subsystem for Linux as of 2018? I searched around, and currently there are two methods suggested; installing an enhancement for Windows Subsystem for Linux and installing an XServer.  I want to know which method is the most hassle-free (easy to install AND to use), and which one is less memory-heavy.  I just want Synaptic and CMake. Why couldn't that be a builtin feature?
