I have bee months trying to revive a PC that is so old, people that I told about it just say to junk it. But I believe that there is a Linux OS out there that can help me out.  The Type of PC that I'm trying to Revive is a 2001 Gateway Desktop with an Intel Pentium 4 processor. The Processing speed is 1.50Gz, and the System Bus Speed is 400MHz. The Cache RAM is 256KB and the total Memory with a friend's Driver that I installed on it is 512MB but 256MB with the one it came with. It also runs on Windows xp but the OS is messed up. Its so slow that I booted up Lubuntu up there once (and that was my only time), and it was lagging a lot. I tested on my laptop (HP AMD Turion 64x2 with 2GB RAM), and it worked perfectly. Ubuntu or any OS Linux can I install on my computer?
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?
Why do some adjectives follow the nouns they modify? Right now I can only think of one instance in which this regularly occurs.  The adjective proper is sometimes placed after the noun it modifies, e.g:      A class of cold-blooded oviparous or ovoviviparous vertebrated animals whose skin is covered with scales or scutes; the reptiles proper.   What is this word order called, and why is it ever used?  Edit: I really want to know about proper, and while the word hyperbaton relates to post-positivity when it is meant to be rhetorically impacting, it doesn't seem to fit with ubiquitous post-positivity, such as that of proper.  I've accepted hyperbaton as the correct term/reason for almost all post-positive constructions, but I'd like a complete answer to include proper. What is vertex and edge shading? When does a .com domain become available after it expires?

I'm not really sure how this would fit in with the current structure of SE.   Oftentimes after asking a question, maybe after an hour or so, I end up finding the answer I needed somewhere. And it comes time for me to answer the most difficult question of all: do I delete this question, or do I keep it in case someone answers and others may benefit from it. The problem is, if I don't delete it and no one answers, my acceptance rate goes down. So usually I'll just delete it.  However, sometimes I fear that someone is typing a really really long answer to my question since itäs only been an hour, and so I imagine the nightmare that person experiences when they find out their essay will be gone to waste. Overall, this never-to-be-seen-again answer could have benefitted many people had the question remained.  Since SE has gone "live-happy" lately, where answers and comments refresh live, I thought it might be interesting if the original asker of the question (or anyone else for that matter) could see how many people are currently responding to the question (just count, not necessary to display their names). This way, if I know someone is replying, I won't delete the question, and others can benefit from it. Fedora 14 uses vi by default when one runs visudo. Is there a way to change this to something else? How did Rutherford conclude that most of the mass (as well as the positive charge) was concentrated in the nucleus? Geiger and Marsden's experiment led Rutherford to believe that the positive charge and most of the mass of the atom was concentrated in a small region. I understand what led him to conclude the way the positive charge is positioned in the atom. But how did he conclude that most of the mass was in a small region (the nucleus)?  How did the distribution of the mass matter after all? Given that the electric force is greater than the gravitational force by many magnitudes, the force between the positice charge and the electrons was predominantly electric.   So how did Rutherford conclude that most of the mass is in the nucleus? Is there a command prompt  equivalent for Windows 7? That is, I want to filter out the results of a command:  Bash use:  ls | grep root  What would it be from a Windows command prompt? Is it possible to embed a pre-existing DLL into a compiled C# executable (so that you only have one file to distribute)? If it is possible, how would one go about doing it?  Normally, I'm cool with just leaving the DLLs outside and having the setup program handle everything, but there have been a couple of people at work who have asked me this and I honestly don't know. How to create old looking/ cracked glass I am looking for old looking cracked glass for a window in a shack scene. I have looked everywhere but can find a tutorial or material or model on this please can someone help me on this thanks I am trying to take pictures of large rugs. The rug size is about 10mx5m, and I'm  planning to purchase , and Canon 7D Mark II with Canon EF 50MM F/1.2L USM lens, since we need high quality images.  We want to set up a studio to take giga-pixel quality images of the large rugs for museum conservation purposes  Could you please suggest the best way for mounting the camera to the ceiling, and any other recommendations for my camera/lens setup, and required lighting? It will be  an indoor shoot. Just we want to setup a studio to shoot the large rugs. Is it completely against the Java way to create struct like objects?  class SomeData1 {     public int x;     public int y; }   I can see a class with accessors and mutators being more Java like.  class SomeData2 {     int getX();     void setX(int x);      int getY();     void setY(int y);      private int x;     private int y; }   The class from the first example is notationally convenient.  // a function in a class public int f(SomeData1 d) {     return (3 * d.x) / d.y; }   This is not as convenient.  // a function in a class public int f(SomeData2 d) {     return (3 * d.getX()) / d.getY(); } "Use Option as Meta key" with ability to type the # symbol I am using Terminal version 2.5, where I have two requirements:  I need to be able to type the Meta key. I need to be able to type the # character, too (Option+3 for the UK keyboard layout)  How can I satisfy both of these? By default, (2) is satisfied, but (1) is not. I can then turn on &quot;Use Option as Meta key&quot;, which satisfies (1), but breaks requirement (2). How can I have both? (It shouldn't be so hard for me to just be able to type.) Edit: what I'm looking for, for example, might be a way to just &quot;Use Option as Meta key&quot; for the left/right Option key, or a way to override the &quot;Use Option as Meta key&quot; for the sole exception of the # character. I just bought a Ryanair plane ticket except that I did not see the QR code on the boarding pass, is that normal? the message is &quot;&quot;. thank you. $\gcd(a,b)\!=\!1\!=\!\gcd(a,c)\Rightarrow\gcd(a,bc)\!=\!1$ [coprimes to $\,a\,$ are product closed] How do I go about proving this?  If $\gcd(a,b)=1$ and $\gcd(a,c)=1$, then $\gcd(a,bc)=1$. I'm very confused with gcd proofs. A subgroup of a cyclic group is cyclic - Understanding Proof I'm having some trouble understanding the proof of the following theorem  A subgroup of a cyclic group is cyclic  I will list each step of the proof in my textbook and indicate the places that I'm confused and hopefully somewhere out there can clear some things up for me.  Proof Let  G be a cyclic group generated by &quot;$a$&quot; and let H be a subgroup of G. If $H = {\{e\}}$, then $H \text{ = &lt;e&gt;}$ is cyclic. If $H \neq \space {\{e\}}$, then $a^n \in H$ for some $n \in \mathbb{Z}^{+}$. Let $m$ be the smallest integer in $\mathbb{Z}^{+}$ such that $a^m \in H$. We claim that $c = a^m$ generates H; that is, $$H \space = \space &lt;a^m&gt; \space = \space &lt;c&gt;.$$ We must show that every $b \in H$ is a power of c. Since $b \in H$ and $H \leq G$, we have $b = a^n$ for some $n$. Find $q$ and $r$ such that $$ n = mq + r \space \space \space \space for \space \space \space 0 \leq r &lt; m,$$  Alright this is the first part in the proof where I start to get confused. Where does the division algorithm come from and why are we using it? The proof continues as follows:  $$a^n = a^{mq + r} = (a^m)^q \cdot a^r,$$ so $$ a^r = (a^m)^{-q} \cdot a^n.$$ Now since $a^n \in H$, $a^m \in H$, and $H$ is a group, both $(a^m)^{-q}$ and $a^n$ are in $H$. Thus $$(a^m)^{-q} \cdot a^n \in H; \space \space \space \text{that is,} \space \space a^r \in H.$$  This is another point at which I’m a little confused. What exactly about $a^n$ and $a^m$ being elements of $H$ allows us to accept that $(a^m)^{-q}$ and $a^{n}$ are in $H$? The proof continues:  Since $m$ was the smallest positive integer such that $a^m \in H$ and $0$ $\leq r$ $&lt; m$, we must have $r = 0$. Thus $n = qm$ and $$b \space = \space a^n \space = \space (a^m)^q \space = \space c^q,$$ so b is a power of c.  This final step is confusing as well, but I think its just because of the previous parts I was confused about. Any help in understanding this proof would be greatly appreciated Is it possible to add new predictions/autofill in Overleaf? For example, when I use the command (in Overleaf/ShareLaTex):  \begin{figure}[H]     \centering     \includegraphics{some_graphic}     \caption{some_caption}     \label{fig:some_label} \end{figure}   the \includegraphics{} comes without the [] parameter to change the size of the image, and \begin{figure} without the [H] option by default.   Is it possible to renew the command to make it default? By that I mean that when I type the \begin{figure} command it adds the [H] and [h] as well as [width=\textwidth] in the \includegraphics command, rather than making a global change in the preamble e.g. Question Staging SE Been a few blogs on , and I get the point. However, would a staging SE help solve some of these issues like community overlap. I understand , but how can someone not yet a part of a community know to do so. Some of the point of SO is that you often don't know what to ask exactly, and we help clear that up. So, I wonder, rather than &quot;playing hot potato&quot; would it be useful to have a site that's simply for temporarily holding questions and such.  It would be the alternative to migrating to another site where you dump all responsibility on that site. This area, all communities are responsible for. It would be a good place to ask a question if you don't know where to ask. The blog I linked talks about phrasing to a specific audience. For someone that doesn't know, the audience is better at selecting which questions are directed at them. As SE grows, the amount of communities will mean more overlap. Right now it may be reasonable to expect people to be able to predict the best community, but will it always be that way?  Some restrictions:  It would be accessible by all communities. The question could be edited, but not answered. The question could be exposed to more easily tracked/understood/etc. automated janitorial work.  Just a helpful thought.
