  • SQLAlchemy - SQLite for testing and Postgresql for devlopment - How to port?

    - by StackUnderflow
    I want to use sqlite memory database for all my testing and Postgresql for my development/production server. But the SQL syntax is not same in both dbs. for ex: SQLite has autoincrement, and Postgresql has serial Is it easy to port the SQL script from sqlite to postgresql... what are your solutions? If you want me to use standard SQL, how should I go about generating primary key in both the databases?

  • Basic SQL Select in Postgresql fails

    - by Rhubarb
    I am doing a select * on a postgresql table, and everything looks good. But if I do: SELECT Name from People It says: ERROR: column People.Name does not exist SQL state: 42703 Character: 8 But the name column shows up during select *. I've tried: SELECT People.Name from People as well, with the same result. Am I missing something? It should be pretty easy to do this in any other database.

  • Per-process CPU usage on Win95 / Win98 / WinME

    - by Hugh Allen
    How can you programmatically measure per-process (or better, per-thread) CPU usage under windows 95, windows 98 and windows ME? If it requires the DDK, where can you obtain that? Please note the Win9x requirement. It's easy on NT. EDIT: I tried installing the Win95/98 version of WMI, but Win32_Process.KernelModeTime and Win32_Process.UserModeTime return Null (as do most Win32_Process properties under win9x).

  • What is the best way to use whitespace while programming?

    - by Emmanuel Smith
    I'm fairly new to programming and from learning I have seen different ways of formatting code, comments, etc; and have been recommended on different techniques. I mostly program in C#, C++, and Java so I want to know what is the the best way to layout code so that if other people where to go through it, they would be impressed by how simple and easy to understand it is. I would like to know the same thing for commenting as well.

  • MySQL query String contains

    - by arik-so
    Hello. This may sound easy, but I've been trying - in vain, apparently - to figure out how I can make a query with MySQL that checks if the value (string $haystack ;) ) in a certain column contains certain data ( $needle ;) ), like this: mysql_query(" SELECT * FROM `table` WHERE `column`.contains('{$needle}') "); In PHP, the function is called substr($haystack, $needle), so maybe: WHERE substr(`column`, '{$needle}')=1 Thanks in advance!

  • How do faces in .obj work?

    - by Adl
    Hi When parsing an .obj-file, with vertices and vertex-faces, it is easy to pass the vertices to the shader and the use glDrawElements using the vertex-faces. When parsing an .obj-file, with vertices and texture-coordinates, another type of face occur: texture-coordinate faces. When displaying textures, apart from loading images, binding them and passing texture coordinates into the parser, how to use the texture-coordinate faces? They differ from the vertex-faces and I suppose that the texture-coordinate faces have a purpose when displaying textures? Regards Niclas

  • ARM assembly puzzle

    - by ivant
    First of all, I'm not sure if solution even exists. I spent more than a couple of hours trying to come up with one, so beware. The problem: r1 contains an arbitrary integer, flags are not set according to its value. Set r0 to 1 if r1 is 0x80000000, to 0 otherwise, using only two instructions. It's easy to do that in 3 instructions (there are many ways), however doing it in 2 seems very hard, and may very well be impossible.

  • msys+mingw - is there installer or at least .tar.lzma/.zip?

    - by Maciej Piechotka
    I try to install n'th time the msys+mingw - however with little success. I need the minimal developer system (standard tools such as sed/awk+autotools+gcc) however each time something is not working (for example currently when I try to run autotools m4 goes into some error loop on AC_INIT). I know they stopped providing installer 'for easy update of components' and they are working on something but maybe there is something unofficial.

  • Animate a GIF using Core Animation layers?

    - by Cliff
    I'm trying to animate a GIF and I hit a roadblock. I have an example of what I'm trying to do that uses the individual frames of the GIF and setting the animationImages property of a UIView. However in my project, the thing I want to animate is drawn using Layers. I'm looking for a quick and easy way to animate the frames without introducing too much complexity. Is there any animationImages equivalent with Layers? Does anybody have any ideas?

  • Is there a repo where you can download android virtual devices?

    - by thepearson
    Does anyone know, if vendors provide or if there is a site where one could download AVD profiles for existing android devices on the market so you can run your apps in the emulator and basically see how they will run on said devices? I know it's pretty easy to create a new device but it'd be great if one could just download the config file for each device and run it.

  • jQuery detect visible but hidden elements

    - by IP
    This seems like it should be fairly easy - but I can't find the right selector for it According to the docs (http://api.jquery.com/hidden-selector/ and http://api.jquery.com/visible-selector/)... Elements can be considered hidden for several reasons: An ancestor element is hidden, so the element is not shown on the page. What I want to detect is "this element is visible, but is contained in a hidden parent". Ie, if I made the parent visible, this element would also be visible.
