  • I've heard that LaTeX is Turing complete. Are there any programs written in LaTeX?

    - by ire_and_curses
    It's possible to do interesting things with what would ordinarily be thought of as typesetting languages. For example, you can construct the Mandelbrot set using postscript. It is suggested in this MathOverflow question that LaTeX may be Turing-complete. This implies the ability to write arbitrary programs (although it may not be easy!). Does anyone know of any concrete example of such a program in LaTeX, which does something highly unusual with the language?

  • Notepad++ like "multi editing" in VIM?

    - by proto-n
    I'm switching from Notepad++ to VIM as main text editor. Notepad++ can have multiple cursors by holding down ctrl and clicking anywhere in the text, so if you type, the text appears in multiple locations. Is it possible in vim? Something like insert after selecting multiple rows in visual mode, but with the possibility to have cursors anywhere in the text. It's a feature I rarely use, also it's quite easily avoidable, I'm just curious, since its the only one I could't find a replacement for in vim yet.

  • How are the concepts of process and threads implementated in Linux kernel?

    - by Shan
    Can any one explain how are the concepts of process and threads implemented in Linux kernel ? I am looking for an intuitive explanation with some C snippets ( and important data structures) that clearly distinguishes between the two. I am just looking for the key implementation ideas I should get hold off. Essentially, I want to understand them and implement something similar in an embedded target (not supporte by any OS) in C language.

  • Windows7 explorer context strip hook?

    - by aceman
    Hy everybody, I'm wondering if it's possible to add a new button via C++ or C# to windows 7 explorer "context strip"(don't know if this is correct name) - like on picture below. My reason for this is because a lot of times I'm switching on&off "Show hidden files, folders and drives" functionality under Tools-Folder option-View. Therefore i want to simplify this process with a click of a button. I was looking into ShellExecteEx function, but I am not sure I can do that. Can Anybody direct me in right direction? thanks, regards

  • Should I still use querystrings for page number, etc, when using ASP.NET 4 URL Routing?

    - by Scott
    I am switching from Intelligencia's UrlRewriter to the new web forms routing in ASP.NET 4.0. I have it working great for basic pages, however, in my e-commerce site, when browsing category pages, I previously used querystrings that were built into my pager control to control paging. An old url (with UrlRewriting) would be: http://www.mysite.com/Category/Arts-and-Crafts_17 I now have a MapPageRoute defined in global.asax as: routes.MapPageRoute("category-browse", "Category/{name}_{id}", ~/CategoryPage.aspx"); This works great. Now, somebody clicks to go to page 2. Previously I would have just tacked on ?page=2 as the querystring. Now, How do I handle this using web forms routing? I know I can do something like: http://www.mysite.com/Category/Arts-and-Crafts_17/page/2 But in addition to page, I can have filters, age ranges, gender, etc. Should I just keep defining routes that handle these variables, or should I continue using querystrings and can I define a route that allows me to use my querstrings like before?

  • How can I write faster JavaScript?

    - by a paid nerd
    I'm writing an HTML5 canvas visualization. According to the Chrome Developer Tools profiler, 90% of the work is being done in (program), which I assume is the V8 interpreter at work calling functions and switching contexts and whatnot. Other than logic optimizations (e.g., only redrawing parts of the visualization that have changed), what can I do to optimize the CPU usage of my JavaScript? I'm willing to sacrifice some amount of readability and extensibility for performance. Is there a big list I'm missing because my Google skills suck? I have some ideas but I'm not sure if they're worth it: Limit function calls When possible, use arrays instead of objects and properties Use variables for math operation results as much as possible Cache common math operations such as Math.PI / 180 Use sin and cos approximation functions instead of Math.sin() and Math.cos() Reuse objects when passing around data instead of creating new ones Replace Math.abs() with ~~ Study jsperf.com until my eyes bleed Use a preprocessor on my JavaScript to do some of the above operations

  • Struts1 and Spring wiring question

    - by Dev er dev
    Recently I had a pleasure of working again on Struts 1.1 application. It uses Spring 2.5, but not for actions. I would like to hook it up to use Spring as DI for Struts Actions also, as it would make my life a loot easier. I found out DelegatingRequestProcessor could be used for this purpose, at least according to documentation, but seems it has been deprecated as of Spring 3.0. Switching to the new version of Struts is not an option. Does anyone have better idea then starting to use deprecated stuff?

  • Symlink in windows XP

    - by willson
    Hi, there. The question is how to make the similar thing like symlink in windows like in *nix. It's really hard to write whole path to the file in console (even using [tab], it's not the way if you need to change language). Adding everything in PATH is tiring too. It'll be great to make a symlink running one command. Actually I'm looking for console app.

  • Project Implementation estimates with TDD

    - by panzerschreck
    Are there any guidelines when quoting estimates for projects/tasks involving TDD? For example, when compared to normal development of a task taking 1 day to complete, how much more should a TDD driven task take? 50% more time or 70% more time? Are there any statistics available, assuming the developer is well versed with the language and the test framework?

  • how to store assembly in memory

    - by da cheng
    Hi, I have a question about how to store the assembly language in memory,when I compile the C-code in assembly, and run by "step", I can see the address of each instruction, but is there a way to change the start address of the code in the memory? Second question is, can I break the assembly code into two? I am curious about how the machine store the assembly code. BTW, I am working on a MACBOOK Pro, duo core. Thank you. -da

  • Tutorials for an experienced C# user to learn C++

    - by Tim R.
    Are there any good resources for learning C++ that a C# user could use, which don't require knowledge of C? I have quite a good knowledge of C# via courses in my University's game development program (in a 300 level course right now) but now I need to use C++ for a project. I would use a beginner tutorial but they are so hard for me to follow and learn the basic syntax because they start so slowly. I found a few of tutorials for switching from C++ to C#, but none in the other direction. I do have a little bit of Objective C practice from iPhone programming as well.

  • Portable way to get file size in C/C++

    - by chmike
    I need to determin the byte size of a file. The coding language is C++ and the code should work with Linux, windows and any other operating system. This implies using standard C or C++ functions/classes. This trivial need has apparently no trivial solution.

  • how to get started with TopCoder to update/develop algorithm skills ?

    - by KaluSingh Gabbar
    at workplace, the work I do is hardly near to challenging and doing that I think I might be loosing the skills to look at a completely new problem and think about different ideas to solve it. A friend suggested TopCoder.com to me, but looking at the overwhelming number of problems I can not decide how to get started? what I want is to sharpen my techniques ( not particular language or framework ).
