• Webmatrix fails to connect PHP website to MySQL

  - by Roni

  I downloaded the latest versions of Webmatrix and MySQL. I downloaded a PHP-MySQL Connector: http://dev.mysql.com/downloads/connector/php-mysqlnd/ In the "Databases" Workspace I pressed "New Connection" button and choose "MySQL Connection" In the Dialog box I filled-in all connection details -- It looks like the database was added. But then when I double-click on the database, I get a short error message saying it cannot connect. I tried everything, searched the web... I'm sure it's a very simple question, so please whoever can help I'll be grateful. I think best solution for me would be if someone could please just give me a link to download of: Webmatrix,MySQL,Connector; and instructions on how to install and then how to connect. This would be the safest way to help me.

• Writing a basic C Shell - understanding argv[] [on hold]

  - by Flame

  I have an assignment for my class to write a basic C Shell. I have found many pages that explain parts of it and some fully implemented code. I'm not going to copy, i'm just using it right now as a way to get started. So I'm at the beginning of this project obviously. One example I am looking at parses the user's input and stores a pointer to the beginning of the argument in char *argv[3]; Am I just misunderstanding this or would this technically break if there are more than 3 arguments? (say /a.out arg1 arg2 arg3 etc). Would I wanna malloc this somehow? I know a.out is considered argv[0], and the arguments argv1 - however many there are. It's probably bad practice to have too many arguments for a program, but I still would at least want to address it as I don't know what my TA's are going to use to test my shell.

• What is the SEO-recommended method for using underscores and dashes in URLs that contain geographic locations?

  - by ElHaix

  In reading through this article: In Subfolder & File Names, Use Dashes, Not Underscores Good: Good: http://www.domain.com/sub-folder/file-name.htm Bad: http://www.domain.com/sub_folder/file_name.htm In my URL's, I may have one or two city names, ending with the province/state: Burnaby_New_Westminister-BC/[some search term]. My URL rules currently are defined such that everything after the dash is the prov/state. Some geographic locations already contain dashes: Notre-Dame-de-Grâce (in QC), which I would convert to ~/Notre_Dame_de_Grace-QC/ I thought of placing the prov/state after another "/", however in some cases the province/state name may not exist, thus ~/Notre_Dame_de_Grace/, so the first term after the domain name contains the geo location {city, city_name-state}. I am now revisiting this, and wondering if this rule set should change, and if so, what is the recommended way of implementing this? -- UPDATE -- After reviewing this video, I see that I should be using the dashes, rather than underscores. However since I still want to have my geo locations in the first URL section, is there anything wrong with using a double-dash separator - ie: /city-name--state/ ?

• A proper file monitoring tool for Windows with notifications

  - by nevvermind

  Developing in PHP, I'm usually confronted with various log files: apache, web apps, error logs etc. I'm currently using Notepad++ with the option to notify me when a file has changed. But when I need to monitor many files, I end up with too many tabs opened. I've used some of these, but they were lacking some basic stuff (like double clicking on the file to open it; oh, c'mon). What do you guys use for monitoring file changes? I needn't be "modern" or fancy. Just a simple "Hey, this file was changed. Here, click on it to open". (Maybe I'll end up making one myself, but I need to learn some more Java).

• configuring separate X screens instead of TwinView

  - by fimre

  My Sony Vaio laptop is connected to an external Samsung monitor and my nVidia driver is configured in TwinView mode. Everything is OK with this, however, I can not adjust my displays individually so at the moment my external display is a little bit darker which disturbs me a lot. I tried the Separate X Screen mode but after restart, my laptop display was white with a black x sign mouse pointer and the external display normal desktop. Is it a bug or something I missed? The idea is that using Separate X Screen mode, I could adjust my displays individually. I would really appreciate someone would guide me out of this situation. Thanx in adv..

• Where to go from here, how to improve / learn more

  - by bExplosion

  I finished University around 4 years ago double degree in Software Eng/Comp Sci. Got my first job at a startup in my final year, was with them for 2.5 years then started my own business. So far everything is going great, lots of clients and stead work etc, but coming right out of uni and into a start up I never had any form or senior software engineer guiding my work or suggesting improvements etc... Whats the best way for me to improve & learn more? Books? MS Exams? Other? I develop in C#, ASP.NET/MVC. Update The problem isn't really with releasing products, I've released quite a few which are up and running with customers happy. It's more with quality of code, best practices, how do I know something I am code is correct, it may work but there may be ways of coding it much more efficiently or by adhering to some kind of standard Cheers for any responses!

• Why can't I mount the Ubuntu 12.04 installer ISOs in Mac OS X?

  - by eric

  Over the past few days, I have downloaded both the 32 and 64 bit version of server and desktop to install on an Intel based PC. It is normal from within OS X to double click on an ISO and it will mount the ISO in the finder as well as within disk utility. When I attempt to mount any of the Ubuntu ISOs I downloaded, OS X returns the error message The following disk images couldn't be opened. The reason given for the error is no mountable filesystem. However, I am still able to open the ISO directly from disk utility and burn it to a DVD/CD. What has changed in this release to cause this? Is there something wrong with the current ISOs? The OS X machine I am using is only two weeks old and is having no issues with any other ISO.

• Enable permanent vertical and horizontal scroll bars

  - by Rolen Koh

  I am facing a problem and it is in Ubuntu (14.04) permanent scroll bar is not there but it appears when you move the mouse pointer to right most side or bottom most side. But it is very difficult to use and lately it takes too much to appear and sometimes it doesn't appear at all and so i have to close the application and reopen it. So i want to ask how to enable permanent scroll bars on right side and bottom most side. I am sure many people must have faced this problem before me. Thanks. P.S: By permanent i mean scroll bars should be visible all the time.

• Hangs on Splash Screen after login (auto-login), how can I fix this?

  - by Davious

  Computer: Toshiba Terca A4 OS: Ubuntu Desktop 10.10 After installing 10.10, the splash screen hangs and the mouse pointer appears. Anyone know what I can do to fix this? ~/.xsession-errors has (nautilus:3190): GConf-CRITICAL **: gconf_value_free: assertion `value != NULL' failed btw, Safe-mode works: I do a Ctrl-Alt-F1 into a command prompt session and run ps aux | grep slave then sudo kill [id of gdm-simple-slave] That killed the session and allowed me to login in safe-mode. Safe-mode works. Then I open a terminal and run ps aux | grep nm- sudo kill -9 [id of nm-applet] nm-applet --sm-disable & to get my internet connection up.

• Are these interview questions too difficult for entry-level C++ positions?

  - by Banana

  I recently had a few interviews for programming jobs within the financial industry. I am looking for entry-level positions as I specify in the cover letter. However I am usually asked questions such as: - all two-letters commands you know in unix - representation of float/double numbers (ieee standard) - segmentation fault memory dump, and related issues - all functions you know to convert string to integer (not just atoi) - how to avoid virtual tables - etc.. Is that the custom? Because I don't think this kind of questions make sense for someone willing to get an entry-level job. Is it totally crazy to think that they should ask more conceptual questions? This is beginning to driving me nuts, honestly. Thanks

• Particles are not moving correctly [closed]

  - by cr33p

  I want to make a particle explosion, after something gets destroyed, but somehow only one line of mixed colors show up on the screen. Here's the header: http://pastebin.com/JW5bPLj2 Here's the source: http://pastebin.com/KHmFqytD I don't get what's wrong, as it's nearly the same as in "Programming Linux Games" Can somebody help me fix that? PS: "Uint32 delta" is needed to update the pixels based on time. PSS: Maybe I should add that it's programmed in C and includes SDL. EDIT: Found the problem. It was the "drawParticles" function. The problem was, that I passed a double to "offset" (as particles[i].x, etc are all doubles). So I ended up with values like ~MAX_INT because I didn't cast the doubles properly to ints.

• How do you ensure consistent experience across multiple graphics cards (or even driver versions)?

  - by Grigory Javadyan

  So I was writing a simple 2D game with OpenGL and SDL and had this problem when there was awful tearing when running in windowed mode (even though I explicitly asked SDL_SetVideoMode to use double buffering). Didn't worry about it all too much because most of the time the game grabs the entire screen, windowed mode is just for debugging. Anyway, yesterday I updated my nVidia drivers and tearing disappeared, the game runs smooth and looks nice in windowed mode too. I can see how the problem may be in the graphics driver, but this leads to a question. Obviously, professional game developers have to deal with a lot of different hardware/software configurations. What are the techniques they use to make sure the game looks the roughly the same on different graphics cards or even the same model of graphics card, but with different driver versions?

• Open file with java application [migrated]

  - by Giaphage47

  I am using Ubuntu. I would like to have a user be able to double-click (or whatever they have set to open a file) on the save file for a java game i'm making, and have the game start and automatically load the save. How could I make the game launch instead of opening the file, and then pass the save's file name or location as an argument? Would i have to have the game create a new mime type the first time it ran, or something similar, so that Ubuntu knows what to do with the save when the user tries to open it?

• Is it correct to refer to a performing programming assignments as a "computer labs"?

  - by Nick Rosencrantz

  Can we say that developing an algorithm is a "laboration"? Are these "labs"? At engineering performing an exercise or an assignement is refered to as "labs" but are those "labs" when in fact it is mainly software problem solving pretty much like numeric methods in math which are not "labs". When studying engineering such as electrical engineering or physics you might do a "laser lab" or a "chemical laboration" if you study chemical engineering for instance. How do you define "lab"? Just performing something experimental? This is sort of double meaning also the physical environment at universities which we call "computer labs" that in fact are just rooms with computers.

• If I use locks, can my algorithm still be lock-free?

  - by Joe Pension

  A common definition of lock-free is that at least one process makes progress. 1 If I have a simple data structure such as a queue, protected by a lock, then one process can always make progress, as one process can acquire the lock, do what it wants, and release it. So does it meet the definition of lock-free? 1 See eg M. Herlihy, V. Luchangco, and M. Moir. Obstruction-free synchronization: Double-ended queues as an example. In Distributed Computing, 2003. "It is lock-free if it ensures only that some thread always makes progress".

• What exactly does an installer do and why might I need one?

  - by Jan

  this is probably the noob-question of the day: So I've written this game. Now there's the .exe file that does the work, a folder with my beautiful, beautiful assets and a bunch of .dll files and other stuff that I probably shouldn't touch. To run the game, I copy the whole lot to the desired computer, double-click the .exe file and start shooting some dudes. Yay! But what exactly is the difference between that and using an installer? What else does an installer do besides copying files and looking more professional than a .zip-file? Is there generally a lot of patching/configuring involved when trying to make a game run on a different computer? I tested my game on all windows computers I could get my greedy fingers on and it works great. Thanks for your time.

• 12.10 nautilus on dell xps 12 does not work

  - by user108664

  I have installed 12.10 on a new Dell XPS 12 ultrabook. Everything seems to work properly right now, including the touch screen, except for nautilus. The left pane works properly, I can select an item on the left and the contents will show up on the right, but when I go to do anything with the contents on the right nothing happens, I can't double click to open, I can't right click to bring up a menu. I can however hold down the left button and to draw a box to select more than one item, but I can't do anything with the selected items. I did not have these problems when I tried 12.04, but unfortunately the touchscreen does not work out of the box on 12.04 and 12.10 seemed to be the faster way go. Any ideas? How can I log what is happening when I try to do anything in nautilus?

• Collision Detection within Player/Enemy Class

  - by user1264811

  I'm making a 2D platform game. Right now I'm just working on making a very generic Player class. I'm wondering if it would be more efficient/better practice to have an ActionListener within the Player class to detect collisions with Enemy objects (also have an ActionListener) or to handle all the collisions in the main world. Furthermore, I'm thinking ahead about how I will handle collisions with the platforms themselves. I've looked into the double boolean arrays to see which tiles players can go to and which they can't. I don't understand how to use this class and the player class at the same time. Thank you.

• Tooltip Support For ASP.NET Image Controls v2010 vol 1

  Tooltip property has been added to DevExpress ASP.NET image controls! Starting with DXperience v2010.1, all DevExpress ASP.NET image controls like the ASPxImage have a new property called: Tooltip. Whats a tooltip? Wikipedia defines it as: The tooltip is a common graphical user interface element. It is used in conjunction with a cursor, usually a mouse pointer. The user hovers the cursor over an item, without clicking it, and a tooltip may appear a small "hover box" with information...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Is it necessary to understand what's happening at the hardware level to be a good programmer?

  - by bev

  I'm a self-taught programmer, just in case this question is answered in CS 101. I've learned and used lots of languages, mostly for my own personal use, but occasionally for professional stuff. It seems that I'm always running into the same wall when I run into trouble programming. For example, I just asked a question on another forum about how to handle a pointer-to-array that was returned by a function. Initially I'm thinking that I simply don't know the proper technique that the designers of C++ set up to handle the situation. But from the answers and discussions that follow I see that I don't really get what happens when something is 'returned'. How deep a level of understanding of the programming process must a good programmer achieve?

• Can't boot - "Waiting for Network Configuration"

  - by user213017

  After an update on 13.10, my PC won't boot Ubuntu any longer. It displays the infamous "Waiting for Network Configuration" message and then hangs. I can go into recovery mode, and choose "Start networking" and then go to a root prompt, and that works fine. Ping works. /etc/network/interfaces contains just the two lines "auto lo" and "iface lo inet loopback". I've double-checked that my network is working, the cable is working (it works on another PC) and the network card seems to indicate a connection. Any suggestions on how to get my PC booted again? Right now I'm limited to a root shell prompt.
