What's the difference between a Long Term Support Release and a Normal Release? What are the differences between an Ubuntu Long Term Support release (LTS) and a normal release? I have searched in %appdata%, pulling up the list of files there, but there is no file labelled .minecraft. Searching %appdata%\.minecraft returns "no results found".   I also opened Minecraft to click on the resources button and could not locate that either. "Can/may/will you help me with this?" Which word to use when we ask for help?  Some conditions:     We know that the person asked is able to do it. We don't know if the person asked is able to do it. Short story (maybe two in the same collection) about Alien education versus Earth I read this somewhere in the 1990s, but it was probably older. I vaguely remember it as being two stories in sequence in an anthology. One was a story involving an Earth administrator comparing Earth curriculum to Mars curriculum and the second was just a class listing for Martian curriculum.  In the first story, what sticks out in my head was the Earth administrator proudly claiming some high value of WPM for reading for his students and the Martian admitting that their rate was lower, and then added a comment along the lines of that the Martian students, when reading at the rate attained at Earth, could not recall every word of the book and recite them back verbatim. In the curriculum listing, I remember that the physical education classes included Tightrope Walking and Advanced Tightrope Walking. In short, the implication was that Mars held its children, and therefore its citizens, to much higher standards, at the cost of sacrificing actual childhood. The children never played, just studied and drilled.  In retrospect, it might not have been Mars... I know one side was Earth and the other was a planet in the Solar System, and Mars sounds about right, but so does Venus. Either way, it was the casual arrogance of the extra-terrestrial society and the blustering attempts of the Earth administrator that stuck out for me. How to set the background color of the Linux console screen? Note: I reworked the question to clarify the issues. This is a trivial question that can be answered in several parts because the question has several attributes.  Unfortunately, the question may be reworked when the person asking the question apprehends (knows) some parts of the answer as well as the structure of the question.  Therefore, the question is presented from a different point of view than the original one.  How to change the color setting¹ of the Linux console, using a shell utility? How to change the color setting¹ of a terminal emulator, using a shell utility?  Originally, I wanted to change the background color of the Linux console during the execution of a shell script. The following proposition works as I wanted.  #!/bin/sh  # set the background color of the terminal tput setab 6 clear  printf "%s\n" 'background: cyan'  # do some tasks  cd /usr/src/initramfs pwd ls -l  # the background of the shell output is cyan   Nonetheless, someone may encounter several glitches (or difficulties).   For instance, if the screen is not cleared, the background color is only applied to the text output, during a shell script execution. If the command tput setab 6 is submitted with the command line and the screen is not cleared, the background color is only applied to a small portion of the output text. If the command tput setab 6 is submitted on the command line and the screen is cleared, the background color is applied to the full screen but only persists until another command is submitted. [...]  ¹ background color Interesting tab on StackOverflow One day I directed to SO and was met with the awesome Interesting page, which I really like. But when I travel away from it, I have to re-enter the query string to get it back. Is there a plan to make this tab visible so I can click to it anytime? I am interested in good integer approximation from below and from above for binary Log(N!).  and  provides only a general idea but not exact values. In other words I need integers A and B so that  A &lt;= Log(N!) &lt;= B Is there a way to get the red artifact in Undertale? My brother has been trying different ways of getting the artifact without the Annoying Dog consuming it, but has been unsuccessful. I'm kind of curious as well. The artifact is obviously a throwing ball, but I kind of want to know the description for the artifact itself, and if you need to cheat to get it... If it even is an item in the code, too. Determining $\lim_{n\to\infty}\left(n^{\tfrac{1}{n}}-1\right)^n$ with only elementary math I am trying to find this limit:  $$\lim_{n\to\infty}\left(n^{\tfrac{1}{n}}-1\right)^n,$$  I tried using exponential function, but I see no way at the moment. I am not allowed to use any kind of differentiation or other topics of advanced math, only induction and school math are possible.

Reduce minimum in call volume I find that the minimum in-call volume on my HTC Desire is still far to loud on some calls.  Since I got the phone, I have flashed several different custom ROMs, radio updates, etc, and have had the issue throughout.  Do you know of any way (setting, hack, app, whatever) to reduce the minimum volume?  My device is rooted and I am currently running one of the CyanogenMod 7 (Gingerbread) nightly builds. In most sentences that use the word lunch, I found this word does rarely take the definite article the. For example:     I have lunch in three hours.      Shall we go out for lunch?      Let's have some lunch.      I'll take my lunch to school.   But now I wonder if this word really cannot take the definite article, and if it can, in what cases do I use the definite article and in what cases not?  And also, if the word lunch cannot take the definite article, why cannot it have it? Is there a power saving application similar to Jupiter? How can I add mp3 files as podcasts to my iPhone using iTunes? I am using iTunes 12.5 on Windows 10 with an iPhone 5s.  Sometimes I download hour-long .mp3 files that I want to put onto my iPhone as podcasts, so that it automatically remembers where I am in my listening if I have to stop in the middle.  I know how to transfer .mp3 files to my iPhone, where they show up as Music.  I also know that I can right click on any song, choose 'Get Info' and under Options change the media kind to 'Podcast.'  But when I change the file to a podcast, it disappears from iTunes, though it does show up on my device when I open the Podcasts app.  How can I transfer an .mp3 file to my iPhone as a podcast, and still have that podcast show up in iTunes when I look there to see what podcasts are on my device? I know that the compiler will sometimes initialize memory with certain patterns such as 0xCD and 0xDD.  What I want to know is when and why this happens.  When  Is this specific to the compiler used?  Do malloc/new and free/delete work in the same way with regard to this?  Is it platform specific?  Will it occur on other operating systems, such as Linux or VxWorks?  Why  My understanding is this only occurs in Win32 debug configuration, and it is used to detect memory overruns and to help the compiler catch exceptions.  Can you give any practical examples as to how this initialization is useful?  I remember reading something (maybe in Code Complete 2) saying that it is good to initialize memory to a known pattern when allocating it, and certain patterns will trigger interrupts in Win32 which will result in exceptions showing in the debugger.  How portable is this? c stdout print without new line? Calculate a determinant with pattern Children's bike problem with back wheel My daughter has sparkle and glitz 12 inch bike with stabilizers (training wheels). Since we purchased the bike every now and again the back wheel keeps spinning when she is pedaling. This seems to happen more when there is a bit of an incline.  Any suggestions what problem could be? How to calculate square root or cube root? I was reading Richard Feynman biography when I read that one time he was able to calculate the  cube root of large number in his brain by just using simple facts of everyday life. So my question is there a way to calculate square root or cube root by using just a pen a paper, I mean a systematic way not by trial and error.
