• design pattern for unit testing? [duplicate]

  - by Maddy.Shik

  This question already has an answer here: Unit testing best practices for a unit testing newbie 4 answers I am beginner in developing test cases, and want to follow good patterns for developing test cases rather than following some person or company's specific ideas. Some people don't make test cases and just develop the way their senior have done in their projects. I am facing lot problems like object dependencies (when want to test method which persist A object i have to first persist B object since A is child of B). Please suggest some good books or sites preferably for learning design pattern for unit test cases. Or reference to some good source code or some discussion for Dos and Donts will do wonder. So that i can avoid doing mistakes be learning from experience of others.

• Why does PHP create these log entries on every page access?

  - by HXCaine

  My server's error log (in cPanel) has an entry for every single time a PHP page is loaded that looks like this (where 'username' has been substituted for my actual username): [2012-06-09 09:02:07]: info: [usr/grp]: username/username cmd: /home/username/public_html/error.php php: /usr/local/php53/bin/php I know it's only an 'info' message but it's filling up my error log. It can't be related to the content of my PHP files because it even happens when I load a page with this as its content: <?php phpinfo(); ?> Any ideas on what it means or if I can get rid of it?

• /etc/X11/xorg.conf doesn't exist?

  - by BBetances

  I'm trying to get my video card properly setup to handle 3D acceleration. After searching a bit, I've come across a few howtos that tell me I need to edit my xorg.conf file. That file doesn't exist. X.org is installed by default, I'm sure, and I figured this video card would be widely supported. 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 09) Any ideas on how I can get this to work properly and play Starcraft II? Or any game for that matter? No resolution problems or anything, just no 3D rendering.

• Global menu not showing in Ubuntu 12.10 with Unity

  - by William

  I am on Ubuntu 12.10 with Unity shell. I am not quite sure what happened, but today I noticed that the menubar (containing 'File, Edit, etc...') is not appearing on the panel as it used to (i.e. the global application menu), but on the application window under the title bar. The only application that still uses global menu is Chromium. Any ideas what settings may have changed? Also, when I right click on the desktop and select "Change Desktop Background", System Settings opens, instead of the "Appearance" settings. Apparently, here is a related question, with no answer: Global menu and HUD suddenly broken EDIT: I noticed this behavior on three of my computers after an update (I do not remember exactly which packages were updated). Now when I try to run apt-get upgrade, I get: The following packages have been kept back: gnome-control-center gnome-control-center-data I guess something is going on with updates. Any info would be appreciated.

• Making profit from a social network

  - by James P.

  This follows similar questions but I'd like to see if anything particular comes out of it due to the nature of site. In short, I've taken up the role of webmaster for a small social network site and wish to make it profitable to at least cover the running costs. The site is linked to a commerce and presents are offered to members according to the number of points they've accumulated through various actions. The site is running on shared hosting so it's probably dirt cheap but the presents can be expensive as a whole and some money has already been invested into the project. One idea I have is to seek some sponsors that would be willing to offer presents or special offers in return for publicity. I don't know if this will be easy or not. I'm also looking into adapting hosting to perhaps move static files to a cheaper online storage medium (see Ideas for reducing storage needs and/or costs (lots of images)). Other suggestions are welcome.

• Multi-platform Map Application

  - by Mahdi

  I'm working on a web project (PHP, jQuery) which currently using Google Maps powering up the map functionality of the application, however we need to make it multi-platform like you can go to the dashboard and choose one from 5-10 map providers (which Goolge Maps is just one of them) to underlying your map functionality. So, as the application is supposed to show the data on map, almost in every single place we have to deal with the API provided by that specific map provider. Currently we are thinking about revising our modular structure and/or making something like an adapter for each provider to deal with their native syntax but via our standard methods. I wish to have your ideas and your experiences, specially if you ever made an interface for dealing via 2-3 different map providers. That would helps much and I really appreciate that. If you need any further information, just ask me to update the question. Update: As Vicky Chijwani suggested Mapstraction, now I'm also wondering which one is more better (pros & cons), having an adapter implemented on Javascript or PHP?

• Links to facebook.com/company-page redirect to facebook.com

  - by Teo

  For the last 2 days I've been trying to find the reason why the link to my website's Facebook page doesn't work anymore. The link went to facebook.com/company-page, but now redirects to facebook.com. I assume that I mistakenly changed something in the Facebook developer area, but I can't remember what it was. I guess I saw some redirect in the tab, but I'm not sure since it's changing too fast to facebook.com. The original link in the footer is correct: <a href="http://facebook.com/company-page " target="_blank" class="facebook_ico"></a> Any ideas?

• Encrypted Home directory not auto mounting

• Google is not treating two Austrailian schools as separate sites when both are subdomains of qld.edu.au

  - by LuckySpoon

  My question relates to two websites, each of which is a "Calvary Christian College", however in two totally different locations and unrelated to each other entirely (except by name, and domain). All schools in the state are issued a .qld.edu.au, in this case calvary.qld.edu.au and calvarycc.qld.edu.au. Now what's interesting is that these domains are crossing each other in sitelinks for searches such as "calvary christian college townsville" (if you check the sitelinks 2/6 are to a different domain). I've put a demotion in for this ages ago (we control calvary.qld.edu.au), however we're seeing no change on the results page. I have been able to get the owners of calvarycc.qld.edu.au to submit demotions for our domain, which should go in sometime this week. What can we do to tell Google that these websites are not interchangeable, despite both appearing as "subdomains" of qld.edu.au. We can possibly open channels of communication with the administrators of qld.edu.au but will need to tell them what we need to change, and at this point I'm out of ideas.

• Why isn't Stripes popular, even though it's an awesome web framework?

  - by Mr.Chowdary

  I'm new to Stripes. I worked on MVC frameworks like Struts 1.x and 2.x. When I started learning, its features are awesome and very lightweight; it has in-depth validations and offers easy integration with other frameworks too. There are no configurations and everything is simplified with annotations. I don't understand why Stripes is not popular compared with other Java web frameworks like Struts or JSF? I didn't find any drawbacks in Stripes. Any ideas why?

• Ubuntu 12.10 AMD/Intel Hybrid Graphics not working

  - by Marian Lux

  On Ubuntu 12.04 my Sony Vaio VPCSE with Intel® HD Graphics 3000 and AMD Radeon™ HD 6630M worked fine with the Catalyst Control Center version 12.6. Also the switching between integrated and discrete graphic card was working. In both cases, I followed this tutorial. But it is not working on Ubuntu 12.10. I tested the tutorial with the Catalyst Control Center from the Ubuntu Software Center, the version 12.8 and version 12.9. Always the same problem: After installation process I am able to boot in the login-screen. But after entering the password for my username, only the background-image appears. Unity seems not to be starting. I am only able to reach the context-menu by right clicking the mouse button. I also tried his fix, but is also does not work for me. Any ideas what to do to fix this problem?

• How to disable Alert volume from the command line?

  - by Bryce

  There is an option in the Sound Preferences dialog, Sound Effects tab, to toggle Alert volume 'mute'. It works and suffices for my needs to disable the irritating system beep/bell. However, I reinstall systems a LOT for testing purposes and would like to set this setting in a shell script so it's off without having to fiddle with a GUI. But for the life of me I can't seem to find where this can be toggled via a command line tool. I've scanned through gconf-editor, pulseaudio's pacmd, grepped through /etc, even dug through the gnome-volume-control source code, but I am not seeing how this can be set. I gather that gnome-volume-control has changed since a few releases ago. Ideas?

• Delete key assigned to a keyboard shortcut and now doesn't work

  - by Erez Schatz

  I posted this to the ubuntuforums, but got no answer there, so I'm trying here: While going over the keyboard shortcuts (System Preferences Keyboard Shortcuts), I accidentally assigned the delete key to a shortcut. I backspaced and cancelled, but next time I pressed "delete" the key didn't work. I tried creating a new shortcut called Delete and this got me a weird pop up saying "Error while trying to run (Delete) which is linked to the key (Delete)". I removed the shortcut, but it's still assigned. I deleted the custom shortcut, but to no avail. Any ideas? this drives me bonkers, as it's such a used key

• Achieving more fluent movement

  - by Robin92

  I'm working on my first OpenGL 2D game and I've just locked the framerate of my game. However, the way objects move is far from satisfying: they tend to lag, which is shown in this video. I've thought how more fluent animation can be achieved and started getting segmentation faults due to accessing the same object by two different threads. I've tried the following threads' setting: Drawing, creating new objects Moving player, moving objects, deleting objects Currently my application uses this setting: Drawing, creating new objects, moving objects, deleting object Moving player Any ideas would be appreciated. EDIT: I've tried increasing the FPS limit but lags are noticeable even at 200 fps.

• No sound after installing a new Graphics Card

  - by Dan

  I've just upgraded my graphics card to an Asus Geforce 210 and now my system has no sound. I've ran Update Manager and the Additional Drivers utility which installed the latest Nvida driver. The graphics card is connected to my TV via a DVI-to-HDMI (DVI at the PC end) cable for the visual connection, and an audio jack from my onboard soundcard for my audio connection. Any ideas on how to resolve this? I ran this command ubuntu-bug audio And it outputted this: You seem to have configured PulseAudio to use the "pci-0000_05_00.1" card, while you want output from "NFORCE - NVidia CK804". I've tired a bit of messing about with the audio settings but can't get anything to work.

• What php programmer should know?

  - by emchinee

  I've dig the database here and didn't found any answer for my question. What is a standard for a php programmer to know? I mean, literally, what group of language functions, mechanisms, variables should person know to consider oneself a (good) php programmer? (I know 'being good' is beyond language syntax, still I'm considering syntax of plain php only) To give an example what I mean: functions to control http sessions, cookies functions to control connection with databases functions to control file handling functions to control xml etc.. I omit phrases like 'security' or 'patterns' or 'framework' intentionally as it applies to every programming language. Hope I made myself clear, any input appreciated :) Note: Michael J.V. is right claiming that databases are independent from language, so to put my question more precisely and emphasise differences: Practises or security, are some ideas to implement (there is no 'Pattern' object with 'Decorator()' method, is there?) while using databases means knowing a mysqli and a set of its methods.

• Chrome and Catalyst - no tab text

  - by Martin Fejes

  I just installed Ubuntu, updated, installed AMD proprietary drivers (for my Radeon HD6870) and noticed that some (most) of the tabs in Google Chrome don't have text, only the favicon. My first idea was that maybe 13.10 may have some issues with the new drivers so I switched to the normal driver instead of the beta one. It was not good. Okay then, I put back the open source drivers. It worked. Okay, it's strange. Let's install Ubuntu Gnome to see if it's Unity. No it was not. Let's install Ubuntu 13.04. Same behavoir. By this time I was desperate. I installed Fedora, the problem was there. Now I'm back to Ubuntu 13.10, but am out of ideas. Could anyone help me, please? P.s.: I can upload a screenshot, if needed.

• Align tetrahedrons

  - by thedeadlybutter

  I'm currently generating tetrahedron meshes in Unity When a player clicks the side of a mesh, a new one spawns aligned with it, like this. I'm not sure how nor can I find any information on implementing a tetra hedron grid. I tried playing around with the vertices until I realized I need to adjust position & rotation. Any ideas? EDIT: To be clear, the second image was manually placed objects in the Unity Editor. I'm looking to make an algorithm that places the meshes correctly.

• Update from Ola Hallengren: Target multiple devices during SQL Server backup

  - by Greg Low

  Ola has produced another update of his database management scripts. If you haven't taken a look at them, you should. At the very least, they'll give you good ideas about what to implement and how others have done so. The latest update allows targeting multiple devices during backup. This is available in native SQL Server backup and can be helpful with very large databases. Ola's scripts now support it as well.Details are here: http://ola.hallengren.com/sql-server-backup.html http://ola.hallengren.com/versions.html The following example shows it backing up to 4 files on 4 drives, one file on each drive:EXECUTE dbo.DatabaseBackup@Databases = 'USER_DATABASES',@Directory = 'C:\Backup, D:\Backup, E:\Backup, F:\Backup',@BackupType = 'FULL',@Compress = 'Y',@NumberOfFiles = 4And this example shows backing up to 16 files on 4 drives, 4 files on each drive: EXECUTE dbo.DatabaseBackup@Databases = 'USER_DATABASES',@Directory = 'C:\Backup, D:\Backup, E:\Backup, F:\Backup',@BackupType = 'FULL',@Compress = 'Y',@NumberOfFiles = 16Ola mentioned that you can now back up to up to 64 drives.

• System Error Report /usr/bin/Xorg

  - by jimirings

  I have recently begun getting a System Error Report message when I start up my computer. I haven't installed anything recently other than the usual updates or done anything else out of the ordinary. The details for the report just say "/usr/bin/Xorg". It doesn't seem to be causing me any problems beyond the annoying error message. I saw these questions regarding this problem: System Error Report - Xorg How do I enable or disable Apport? That's all dandy for getting the message to go away, but I'd rather fix the problem. Any ideas how I can make that happen? I'm running Ubuntu 12.04 on a Toshiba NB505. I am, of course, happy to provide any other relevant information that may be needed. Thanks in advance.

• C# creating a simple snake game

  - by Guy David

  I was thinking about creating a snake game with C#, so I ran ideas in my head, and some problems came up. How can I track and output in the correct location the blocks that run after the snake's head? If the snake is built of five blocks, and the user starts going in a circle, how can I print the snake body in the right location? Also, how can I create an action that will run on the background, which will move the snake forward, no matter what the user does? What structure should my code have? (code design structure) This should be a console application, since it's the only framework I am familiar with. I am not looking for finished code, since I want to really understand how it should work.
