  • Mounting filesystem with special user id set

    - by qbi
    I want to mount the device /dev/sda3 to the directory /foo/bar/baz. After mounting the directory should have the uid of user johndoe. So I did: sudo -u johndoe mkdir /foo/bar/baz stat -c %U /foo/bar/baz johndoe and added the following line to my /etc/fstab: /dev/sda3 /foo/bar/baz ext4 noexec,noatime,auto,owner,nodev,nosuid,user 0 1 When I do now sudo -u johndoe mount /dev/sda3 the command stat -c %U /foo/bar/baz results in root rather than johndoe. What is the best way to mount this ext4-filesystem with uid johndoe set?

  • Utility Objects–Waitfor Delay Coordinator (SQL Server 2008+)

    - by drsql
    Finally… took longer than I had expected when I wrote this a while back, but I had to move my website and get DNS moved before I could post code… When I write code, I do my best to test that code in as many ways as necessary. One of the last types of tests that is necessary is concurrency testing. Concurrency testing is one of the most difficult types of testing because it takes running multiple processes simultaneously and making sure that you get the correct answers multiple times. This is really...(read more)

    - by whamsicore
    I am finally going to buy a domain I have been looking at. The domain owner wants me to give him my Godaddy account information and send him the payment via Paypal gift, so that there will be no extra charges. Should this cause suspicion? Does Paypal offer any kind of fraud protection? What is the best way to protect myself from fraud in this situation, without the need for escrow services, such as escrow.com? Any advice welcomed. Thanks.

  • How to improve Unity Performance?

    - by Wolter Hellmund
    I installed ubuntu netbook edition on my netbook* expecting to get the best performance out of it, but apparently, that didn't turn out. Unity is a bit slow on it, and when I click on Files and folders it takes a while to load the respective interface and the bar at the top disappears and then loads in. Is this expected? Is there anything I can do to improve the performance? Is this problem specific to my netbook? *Netbook info: Acer - Aspire One 1.6 GHz Intel Atom Processor 1 GB RAM Memory Intel GMA 950 graphics card

  • How to become an expert in Python, PHP and Javascript? [closed]

    - by Andrew Alexander
    So I've been programming for about 9ish months now, and I've taught myself some Python, some PHP and some Javascript. I want to become better at these languages - I can hack something out, but a lot of things like OOP, using lists in the most effective ways, etc, is lost on me. What are the best ways to become an "expert" programmer? Does it depend on the nuances of the language, or is it more general? Is there any math I should be studying alongside it? Obviously a lot depends on what you want to do with it - so far I've mostly done small scale internal applications as well as web programming. How do I find out about good program design?

  • Web Page Execution Internals

    - by octopusgrabbus
    My question is what is the subject area that covers web page execution/loading. I am looking to purchase a book by subject area that covers when things execute or load in a web page, whether it's straight html, html and Javascript, or a PHP page. Is that topic covered by a detailed html book, or should I expect to find information like that in a JavaScript of PHP book? I understand that PHP and Perl execute on the server and that Javascript is client side, and I know there is a lot of on-line documentation describing <html>, <head>, <body>, and so on. I'm just wondering what subject area a book would be in to cover all that, not a discussion of the best book or someone's favorite book, but the subject area.

  • Android opengles 2.0 :different resolutions rendering and input

    - by kkan
    I'm currently developing a sprite based 2D game for android using opengles 2.0. I've got some basic rendering done that mimics the spritebatch functionality of xna (draw sprite, rotation, color). But all of this works for a fixed projection matrix, but android has a lot of screen sizes. Q1)Would this be an okay method to scale up/down the drawing? 1)Draw the whole screen to a texture. 2)Draw the above texture as a quad to the device. I found the above through some searching, not sure if it's the best one, are there any alternatives? Q2)How do you handle inputs for different resolutions? I currently get the position of a touch and use it raw. Would it be okay to get the position, and then scale the position to size of the texture used for rendering, and the perform calculations on it? Thanks.

    There is a news website / blog - I'll call it the Site from now on. The site mention a keyword in one of its articles.

  • "Time Control" in a 2d Platformer

    - by Woody Zantzinger
    I am making a 2d platformer where the player can press a button, and restart the level, only their previous character will also run the level at the same time, like they are traveling back in time. I know other games have done this before, and the way I have thought of doing it is to make the game character have a set of actions (Idle, Jumping, Walking Left etc.) and then detect changes in those actions and log them into a list along with the game time. So then when I need the character to run the level again on its own, I can just go through the list changing its actions at the right time. Is this the best way to do it? Does anyone have any experience in this? Thanks.

  • Intercepting the Unity logout

    - by qbi
    I want to copy some data from another machine to a local computer on a regular basis. At the moment I'm researching different solutions and try to find the one which fits best. Basically I want to open a network connection (or use an existing one), make a VPN connection and start a rsync process. This should be done on every logout of my desktop session or on shutdown. One possible solution might be to somehow intercept the Unity shutdown and execute a script. So is there a possibility to execute a script on GNOME/Unity shutdown? I'm aware that you can do it on system shutdown. How can I do this?

  • Browser window size statistics?

    - by Litso
    I was wondering, are there any statistics available on what size users have their browser set to nowadays? I know the screen resolutions (we have analytics, which shows those as well) but I doubt a lot of people with 1280*xxx and higher still browse full-screen though. My boss is determined to keep our website 900px wide though, because that way people with 1800*xxx resolutions can have two browser windows next to eachother without having to scroll horizontally. I have never seen anyone browse with two adjacent browser windows like that except here at my current job, so I'm kind of doubting whether this is the best decision or just his personal preference. Anyone that can help out here?

  • What source control to use for my private gaming server?h

    - by crosenblum
    It has sql server components, client launcher, server software. I want to use an online resource where people can make updates, and make it easier to roll out any changes to players. Most of the files are just text files, or gtx image files. I don't think this qualifies as open source, so I don't know what to do. I tried github, and have a free account there, but it was really clunky, mass adding every file to be comitted. I really dont' like subversion but if that's the best option, i'll use it. The other people who will need access to the files will have no familiarity with any kind of source control, so I need an easy system for them to download files, make changes, and comit to the repository. Any suggestions?

  • How to write efficient code despite heavy deadlines

    - by gladysbixly
    I am working in an environment wherein we have many projects with strict deadlines on deliverables. We even talk directly to the clients so getting the jobs done and fast is a must. My issue is that i'd always write code for the first solution that comes to my mind, which of course I thought as best at that moment. It always ends up ugly though and i'd later realize that there are better ways to do it but can't afford to change due to time restrictions. Are there any tips by which I could make my code efficient yet deliver on time?

  • Which parallel pattern to use?

    - by Wim Van Houts
    I need to write a server application that fetches mails from different mail servers/mailboxes and then needs to process/analyze these mails. Traditionally, I would do this multi-threaded, launching a thread for fetching mails (or maybe one per mailbox) and then process the mails. We are moving more and more to servers where we have 8+ cores, so I would like to make use of these cores as much as possible (and not use 1 at 100% and leave the seven others untouched). So conceptually, as an example, it would be nice that I could write the application in such a way that two cores are "continuously" fetching emails and four cores are "continuously" processing/analyzing the emails (since processing and analyzing mails is more CPU intensive than fetching mails). This seems like a good concept, but after studying some parallel patterns, I'm not really sure how this is best implemented. None of the patterns really fit. I'm working in VS2012, native C++, but I guess from a design point of view this does not really matter and just some pointers on how to organize this would be great!

  • Programming to ANSI standards (for engineering)

    - by Jake
    I am currently tasked to write a software to help engineers design standard compliant designs. If there is a bad design, software will report an error or warning. Maybe it's just me, but anyone who has done this should be familiar with the massive amounts of ANSI standards tables like this one: http://en.wikipedia.org/wiki/Nominal_Pipe_Size Computers are, as its name suggest, computing machines, not lookup machines. I feel that feeding formulas into computers and churning out standard compliant designs is much more efficient than doing memory intensive data lookups that are prone to human input errors and susceptible to "data updates". I actually think that there are formulas to calculate all those numbers, but nobody so far could give me that information. Anyone been through this before? What is THE best approach to this? Thanks for sharing.

  • ASP.NET RedirectPermanent Method using C# and VB.NET

    301 redirection is essential for the best user experience. If something on your website has been changed or moved to a new permanent location, users will need to be permanently redirected. In addition, search engines can follow this type of redirection, and this redirected-to page will now be the one to rank in Google or other search engines, replacing the old page. There are different ways to implement the RedirectPermanent method. This tutorial will illustrate these common techniques with sample VB.NET or C# code. Creating the Sample ASP.NET 4.0 Website RedirectPermanent is new in ASP.NET 4....

  • GeForce8800 ultra

    I have been running Ubuntu 10.04 with GeForce 8800 Ultra graphics card without any problems for many months until a few days ago, after some updates, everything stopped working.

I have a dual boot and WinXP is not having this problem with the 8800 card. So, elementary... What's going on between Ubuntu and Nvidia? Best regards Gunnar

  • How to avoid circular dependencies between Player and World?

    - by futlib
    I'm working on a 2D game where you can move up, down, left and right. I have essentially two game logic objects: Player: Has a position relative to the world World: Draws the map and the player So far, World depends on Player (i.e. has a reference to it), needing its position to figure out where to draw the player character, and which portion of the map to draw. Now I want to add collision detection to make it impossible for the player to move through walls. The simplest way I can think of is to have the Player ask the World if the intended movement is possible. But that would introduce a circular dependency between Player and World (i.e. each holds a reference to the other), which seems worth avoiding. The only way I came up with is to have the World move the Player, but I find that somewhat unintuitive. What is my best option? Or is avoiding a circular dependency not worth it?

  • How to identify the client is a search robot?

    - by Yau Leung
    I have built my entire site using AJAX (indeed it's GWT). I have also implemented AJAX crawling proposed by Google. However, after the implementation, I found that neither Yahoo , Bing, nor Baidu implemented that scheme! I'm wondering if there is a way to identify the web client is a search robot. If they are, they will be shown the HTML snapshot I created. It will be best if I can identify them in APACHE level, then I can just do a mod_rewrite. But it's still ok if I can do that in PHP or GWT.

  • Java vs COBOL programming examples

    - by Jodi
    I am a COBOL programmer, desperately trying to learn and program Java. Although I understand the OO priciples and concepts, I am at a lost putting all together. I am trying to find some examples on how code will look in COBOL vs Java - something a bit more complicated than "hello world" [I am past that initial headache! :-)], that includes OO principles - basically, a decent 1000+ liner in COBOL, with the Java code to work through. After working through book after book, doing the examples, and even writing small java programs at work, I think working through an example I can compare will be the best way to getting my thinking cap converted, and being able to do in Java what I can do after 10 years with COBOL. Can anybody help?

  • How can I link to callback functions in Lua such that the callbacks will be updated when the scripts are reloaded?

    - by Raptormeat
    I'm implementing Lua scripting in my game using LuaBind, and one of the things I'm not clear on is the logistics of reloading the scripts live ingame. Currently, using the LuaBind C++ class luabind::object, I save references to Lua callbacks directly in the classes that use them. Then I can use luabind::call_function using that object in order to call the Lua code from the C++ code. I haven't tested this yet, but my assumption is that if I reload the scripts, then all the functions will be redefined, BUT the references to the OLD functions will still exist in the form of the luabind::object held by the C++ code. I would like to be able to swap out the old for the new without manually having to manage this for every script hook in the game. How best to change this so the process works? My first thought is to not save a reference to the function directly, but maybe save the function name instead, and grab the function by name every time we want to call it. I'm looking for better ideas!
