i have windows 8.1 currently and i want to switch to Ubuntu especially or any Linux OS would be fine and my computer specs are as below:  Processor:Intel(R)Pentium(R)D CPU 2.66GHz 2.67GHz RAM: 1.25GB System Type: 32bit Operating System, X64 Based Processor   my PC is very old and as i am school student i dont need a PC better than this still i finish my schooling. Please suggest me a Linux OS,  I dont need Linux for gaming purpose but just for my programming place as such.  Thanks
For a given hardware configuration, how do I find out if Ubuntu will run on it? What considerations should I take into account when choosing an Ubuntu version and  such as:    with a lighter desktop than the usual Gnome and Unity  with the even lighter LXDE desktop   Obviously Ubuntu does not run on some processor architectures. So how do I go about choosing the right version and derivate. How can I find out the minmal system requirements?
Where can I find Vagrant packages? is a tool to build and manage virtual machines for developers.  It has a  guide that contains iffy-looking suggestions like  $ sudo ln -s /usr/bin/ruby1.8 /usr/bin/ruby  # wtf???   or installing RubyGems from source rather than from Ubuntu packages, and then using gem install to install vagrant itself.  I'm not feeling comfortable just following those instructions.  Is there perhaps a PPA?  Are there, perhaps, alternative tools that are packaged for Ubuntu? I am very new to being able to use LaTeX to type up mathematical papers, and I just got my "system" set up. Currently I have installed TexWorks, and MikTex, and I have put together a 'hello world' article which seems to run well.   I have also used the syntax "\usepackage{amsmath}" and "\usepackage{amssymb}" in the beginning of my .tex file to write math symbols, only because some online tutorial said so.   My question is, firstly, are those the only packages I need to use for writing math, and secondly, I remember reading about some shortcuts(?) that can be used for writing math symbols, and/or user defined shortcuts that can be 'set' in the beginning so as to reduce the amount of LaTeX code needed to write mathematical symbols. However, I do not know if this is true, and if it is, how to go about 'installing' such a thing.   Does such a thing exist? Am I able to make my own shortcuts?  Thanks! DML is not allowed in a constructor. Is there a known reason behind this limit?  I have been searching for the answer &amp; haven't found anything which addresses the question. May be it's not documented anywhere(Or google doesn't know where it is). I have made a fancy title page using titleformat and tikz, but I now face the following problem. The \chaptertitlename command returns \chaptername or \appendixname. I would like to spread the letters of the text returned by \chaptertitlename to a given length.  For example I would like to be able to call: \mycommand{\chaptertitlename}{3cm} in order to space the letters of \chaptertitlename on a total length of 3cm. How to do that ?  EDIT: This example illustrates a nearly working thing:  \documentclass[11pt]{article} \usepackage{fontspec} \newcommand{\spreadletters}[2]{\makebox[#2][s]{#1}}  \begin{document} \spreadletters{m y w o r d}{3cm} \end{document}   How to convert myword to m y w o r d ?  EDIT 2: Can someone explain me why the first work and not the second one (and how to make it work) ?  \documentclass[11pt]{book} \usepackage{fontspec} \usepackage{seqsplit} \usepackage[explicit]{titlesec}  \newcommand{\spreadletters}[2]{\makebox[#2][s]{\seqsplit{#1}}}  \begin{document} \chapter{First} \spreadletters{myword}{10cm} \linebreak % This is working \spreadletters{\chaptertitlename}{10cm} % This is not working \end{document} What is the purpose of a Windows Workgroup?

Using adjustbox along with table footnote In Walter Rudin's Principles of mathematical analysis Exercise 5.21, it is proved that for any closed subset $E\subseteq \mathbb{R}$, there exists a smooth function $f$ on $\mathbb{R}$ such that $E=\{x\in \mathbb{R}\mid f(x)=0\}$.   Since $E^c$ is open in $\mathbb{R}$, $E^c$ is a countable disjoint union of open intervals $(a_i,b_i)$. On an interval $(a,b)$, if we let $f(x)=\exp(\frac{1}{(x-a)(x-b)})$, $x\in(a,b)$; $f(x)=0$, $x\notin(a,b)$, ($f(x)=\exp(\frac{1}{(x-a)})$ or $f(x)=\exp(\frac{1}{(x-b)})$ on $(a,\infty)$ and $(-\infty,b)$ resp.), then $f$ is smooth. Hence we can get a smooth function on $\mathbb{R}$ such that $E$ is the zero point sets of $f$.  (1). How about a closed subset $E$ of $\mathbb{R}^n$? is it true that for any closed subset $E\subseteq \mathbb{R}^n$, there exists a smooth function $f$ on $\mathbb{R}^n$ such that $E=\{x\in \mathbb{R}^n\mid f(x)=0\}$?  An open set in $\mathbb{R}^n$ cannot be written as a disjoint union of countable open balls hence the proof above is not valid. The partition of unity only claims that for an  open set $U$, there exists open $V$ in $U$ such that $\bar V\subseteq U$ and a smooth function $f$ on $\mathbb{R}^n$ such that $supp f\subseteq U$, $f|_V=1$.   (2). The taylor series of $f(x)=\exp(\frac{1}{(x-a)(x-b)})$ does not converge around points $a,b$ hence $f$ is not analytic at $a,b$. Is it true that for any closed subset $E\subseteq \mathbb{R}$, there exists an analytic function $f$ on $\mathbb{R}$ such that $E=\{x\in \mathbb{R}\mid f(x)=0\}$? How is floating point stored? When does it matter? In follow up to , it appears that some numbers cannot be represented by floating point at all, and instead are approximated.  How are floating point numbers stored?  Is there a common standard for the different sizes?  What kind of gotchas do I need to watch out for if I use floating point?  Are they cross-language compatible (ie, what conversions do I need to deal with to send a floating point number from a python program to a C program over TCP/IP)? android - out of memory exception when creating bitmap The score for the 4 questions are 111, 1218, 261 and 5 respectively, but they display 2 digits per line. This is an obvious bug in design. Volume control on asus zenbook 3 Using Ubuntu 16 LTS  I installed ubuntu on my new asus zenbook3 ux390. Nearly everything works fine except the volume controls don't work. The volume is either on or off. I can adjust volume in specific apps or websites (like youtube) successfully, but the internal volume control either wants to be muted or at 100%. When do I use the PHP constant "PHP_EOL"?

Collapsing a stream of multiple lines into one line I have a file containing a a large number of lines, each of which contains a bunch of numbers which are separated by spaces. I process this data in a pipe in some way, and then I want to collapse the multiple lines into a single line of all the numbers separated by spaces.  Is there a standard command-line utility I can use to do this? It seems like most line-by-line utilities won't mess with the newlines... number length limit in SOQL Where condition When I execute SOQL in Developer Console:  Select Id, Amount From Opportunity Where Amount &gt; 10000000000   An parsing error occurs:  Unknown error parsing query   Is there length limit of number on SOQL Where condition? Firefox: Downloading files with drag and drop Hypothetically, should I pay off the smaller + higher interest rate loan first, or the larger + higher absolute interest cost? I have this hypothetical situation on my mind and I am not sure which is the best solution. Given:  Loan 1: $340,000 at an interest rate of 1.69% per year Loan 2: $40,000 at an interest rate of  3.6% per year  I have a fixed amount available to pay these, let's say, $1,500 monthly and I can decide how much I want to pay each one (I could pay 750/750, 1000/500, 1500/0 for instance). I do not have a time limit to pay these. My question: What is the optimal way to pay these? What I always heard is: pay the debt that has the highest interest first. This would lead me to a solution: pay loan 2 as fast as possible. But the total amount of interest on 340,000 is higher (in this case, $5780 annually) than the amount over $40,000 (1440, in this case), so, to me, it feels I should pay the Loan 1 first. I would love to run some simulations, but I have no idea how to calculate these things (I don't even have a clue on how to research it). ps: this is really a hypothetical situation, I am not getting such loans without being able to calculate it, don't worry ;) Batch Convert Images from One Format to Another while maintaining directory structure, and removing originals I've looked at , and while it works there a few issues:   All converted images are placed in the directory from which the command is called. The original images are kept.   I need to convert around 70,000 .tif and .jpgs to .pngs.  It's really important the the files when converted are placed in their normal directories.    I can do a batch rm of .tff/.jpg's at the end if that's the best way to handle removing the old files. Let $U_1, \cdots, U_n$ be $n$ i.i.d continuous uniform random variables on $(0,1)$ and their order statistics be $U_{(1)}, \cdots, U_{(n)}$.  Define $D_i=U_{(i)}−U_{(i−1)}$ for $i=1, \cdots, n$ with $U_0=0$.  I am trying to figure out the distribution $\lim_{n\to\infty} \#\{i = 1, \cdots, n \mid nD_i \geq z\}/n$. This must be very well known, but I cannot find a reference.
