I want to call a .C or .O file from my python script and execute any of the C program function. How can I write my script to call a function in C?
What would be the quickest way to construct a Python binding to a C or C++ library?  (I am using Windows if this matters.)
Can Ubuntu use all my 4GB of RAM? Where should the apostrophe go on a possessive abbreviation? When expanding an abbreviation in parentheses, sometimes the thing that was abbreviate was used in a possessive context.  Consider the following example:     If the Giant Ostrich Bomb's (GOB) fuse is too short, you may be too close when it goes off and you may get kicked in the face.   Is the above correct, or should it be rewritten this way instead:     If the Giant Ostrich Bomb (GOB)'s fuse is too short, you may be too close when it goes off and you may get kicked in the face.   If this is a matter of style, do any of the popular style manuals have a recommendation? Dilemma: Present Perfect Or Perfect Continuous? What is the correct name to use with /give for Lapis Lazuli? (Ubuntu 13.04 with GNOME Shell, upgraded, GNOME version 3.8) Recently, I upgraded Ubuntu to 13.04. the default desktop is gnome-shell. Except Nautilus, other software border doesn't disappear when I make them to be maximized. I checked the problem for these software:  LibreOffice Firefox Rhythmbox thunderbird GNOME-Terminal  On the other hand there are three bars on maximized mode:  GNOME Shell panel  Title-bar for software which contains - + x (minimise, maximise, close) buttons.  Software menu-bar  Number &quot;2&quot; is extra. Is a package missing? There is a lot of lag when I play Minecraft. I think this is due to the low amount of RAM I've allocated to Minecraft. (495MB)  How do you allocate more RAM to Minecraft?  I checked my other computer (Intel i5 Core) and it had the same amount of RAM allocated to Minecraft. However, Minecraft did not lag on that computer.  After I installed Optifine on this computer, the lag stopped (I don't know why cause I read that Optifine splits the load onto 2 cores, but I have only one core (At least I think so, a sticker on the laptop says Intel CORE i7)). I have a laptop which I'm going to return due to battery defects. As I have already configured everything on this laptop, I'd like to migrate the installation on the new laptop (when I'll get it). The one to replace has a 128 GB eMMC, and two USB 3 ports. So, I was thinking to   Boot from a Linux live USB from port 1 Make an image with dd of the eMMC, saving it to a external HDD on port 2 Do the reverse on the new laptop   My question is, will it work fine with Windows? Does migrating this way have any issues? Would I be able to restore the installation if the new laptop is a different model with at least 128 GB? When there are too many linked questions to fit in the sidebar, it shows a link to &quot;see more linked questions...&quot;. Clicking on this link takes you to a front-page type showing only the linked questions. You can then use the tabs to sort by &quot;active&quot; to show the most recently active linked questions. However, the gray popup that appears when new questions are posted shows up for any recent activity, not just activity on the linked questions. Clicking through then updates the list, appending more questions to the top of the list, regardless of whether or not they're linked to the question at hand. To reproduce:  Go to  Wait for activity  Screenshots:   Now obviously this isn't a show-stopper, but I thought it might be worth mentioning.  Update June 2020 This is still relevant.  While sitting on the &quot;linked questions&quot; page for a specific question - in the above screenshot,  - and sorted by newest, when a new question is asked the &quot;1 question with new activity&quot; banner will show up, even if that new question does not link back to the question that you were on. Why Process Builder doesn't work on Delete Scenario? Can I install a ROM made for a different device? I own a MicroMax A100. I want to install the latest version of a different ROM (Samsung or Nexus).  Is it possible? If so, can you tell me how?  If not, can I install a ROM made for a different device, but from the same manufacturer? For example, could I install a ROM for the MicroMax A110, which is the successor of A100? Adding Basemaps from Google or Bing in QGIS Why do we need virtual functions in C++? In version 5.2 of Apple's Pages app for OS X (Mavericks), how do I change the page layout? What are the best practices for battery longevity? Install software from packages, or build it from source? This is a  about when to use packaged software and when to build and install it yourself.   When should I install software from packages provided by my OS distribution, instead of building and installing it myself from source?  When is it better to build from source? Lightning Web Component embedded in Visualforce Page via Aura Component and App not displaying I am writing a lightning web component that is going to be used in Salesforce Classic, Lightning Experience and an Employee Community. It does not HAVE to be a lightning web component - I could use a traditional Aura Lightning Component if I must.   However, what I am finding is that the visualforce page does not work, even when the lwc component is embedded in a aura component that is then used with Lightning Components for Visualforce. I can see from the documentation  that using a lwc directly from within visualforce is not supported, but I was under the impression that it may work if wrapped in an aura component.   My question then is this:  Has anyone had success having a lwc wrapped in an aura component display successfully within Visualforce? Or is this completely unsupported behaviour? How to run grep with multiple AND patterns? I would like to get the multi pattern match with implicit AND between patterns, i.e. equivalent to running several greps in a sequence:  grep pattern1 | grep pattern2 | ...   So how to convert it to something like?  grep pattern1 &amp; pattern2 &amp; pattern3   I would like to use single grep because I am building arguments dynamically, so everything has to fit in one string. Using filter is system feature, not grep, so it is not an argument for it.    Don't confuse this question with:  grep "pattern1\|pattern2\|..."   This is an OR multi pattern match. Eclipse: How to build an executable jar with external jar? I am trying to build an executable jar program which depends on external jar downloaded. In my project, I included them in the build path and can be run and debug within eclipse.  When I tried to export it to a jar, I can run the program but I can't when I try to press a button which includes function calls and classes from the external jar. I have edited the environment variables (Windows XP) CLASSPATH to include paths of all the external jar, but it doesn't work.  A point to note is that I got compile warnings while exporting my executable jar, but it doesn't show up any description about the warnings.  Would someone kindly provide a thorough guide on how to include an external jar program using eclipse? Meaning of Sun Lamp Size? In Cycles, a sun lamp is treated as infinitely far away - only the angle matters, not the position. Other lamps have their sizes defined in blender units: a point lamp with size 1 emits light from a area with size of 1. But if a sun lamp at infinity had a size of 1 blender unit, the angular arc of that sun would be nonexistent.  Clearly, when you change the size of a sun lamp, shadows get fuzzier or sharper. But what does that actually mean? What are you changing? How can I do this fast?  Sure I can do this:  static bool ByteArrayCompare(byte[] a1, byte[] a2) {     if (a1.Length != a2.Length)         return false;      for (int i=0; i&lt;a1.Length; i++)         if (a1[i]!=a2[i])             return false;      return true; }   But I'm looking for either a  function or some highly optimized proven way to do this.  java.util.Arrays.equals((sbyte[])(Array)a1, (sbyte[])(Array)a2);   works nicely, but it doesn't look like that would work for x64.  Note my super-fast answer .
