• I cannot change the screen brightness

  - by user1793249

  here's my problem: Ever since I installed Ubuntu 12.10 on my computer I haven't been able to change the screen brightness, it was always set to the maximum. I did take a look at this post: Decrease Backlight Below Minimum And it helped me resolved the issue with the unbearable brightness, however one problem persists: I cannot change it through "Brightness & Lock" or the function buttons (F2 and F3), when I press the buttons, the animation shows up but nothing happens. I tried the following: http://www.refreshit.info/2012/08/solved-brightness-increase-and-decrease.html It did nothing... If it helps: I have an HP-dv6 6185la, it has an ATI Radeon 6770M HD card and an Intel HD Integrated Graphics Card It only detects the "Intel® Sandybridge Mobile" Thanks in advance.

• Is sudo dd taking too long to wipe hard drive?

  - by Adam133718

  I have a 200gb HDD which I removed from a macbook due to several corrupt files in startup. One thing led to another and I decided that I needed to format the drive. I used the command sudo dd if=/dev/zero of=/dev/sdb which is supposed to wipe everything off of the hard drive. It is my understanding that the command writes 0's over every bit on the drive, which I would imagine must take a while. The process has been going for about 18 hours now. I can use other functions of operating system like the web browser and I can even use another terminal window, so I know the system is not frozen. Should I restart the process or let it continue on? Any advice will help. Thanks. By the way, I already noticed a post similar to this that was previously answered though the user was not using the same command as I was.

• What is an achievable way of setting content budgets (e.g. polygon count) for level content in a 3D title?

  - by MrCranky

  In answering this question for swquinn, the answer raised a more pertinent question that I'd like to hear answers to. I'll post our own strategy (promise I won't accept it as the answer), but I'd like to hear others. Specifically: how do you go about setting a sensible budget for your content team. Usually one of the very first questions asked in a development is: what's our polygon budget? Of course, these days it's rare that vertex/poly count alone is the limiting factor, instead shader complexity, fill-rate, lighting complexity, all come into play. What the content team want are some hard numbers / limits to work to such that they have a reasonable expectation that their content, once it actually gets into the engine, will not be too heavy. Given that 'it depends' isn't a particularly useful answer, I'd like to hear a strategy that allows me to give them workable limits without being a) misleading, or b) wrong.

• RewriteRule for URL Subdirectory Root

  - by JYerdon

  Have not found this in my searches on SE. I need this scenario to work: • User visits someurl.com/news/folder or someurl.com/news/somefolder/, they get redirected to someurl.com/somefolder. • If the user visits JUST someurl.com/news or /news/, they are allowed through to visit /news. Here is my current rule: RewriteRule ^news/(.*) /$1 [NC,R=301,L] How do I make it allow the second bullet point? First seems to work with no issues. Thanks all! POST UPDATE I have got the code RewriteCond %{REQUEST_URI} ^news RewriteRule ^/news news/ [NC,L] RewriteCond %{REQUEST_URI} ^/news/(.)$ RewriteRule ^news/(.) /$1 [NC,R=301,L] BUT - it doesn't allow me to go to the URL something.com/news/ Any thoughts?

• What effect does using itemprop="significantLinks" on anchors have for SEO and what is the ideal use?

  - by hdavis84

  I'm practicing application of microdata via http://schema.org. Anyone who's browsed the documentation there knows that there's a lot of need for improvement for more clear understandings on use for each property. My question on this post is more about the "significantLinks" property and how it effects SEO for on page, in content anchored text. Does anyone have any more information regarding whether its good to use for link optimization? I understand what schema.org means that it's to be used on "non-navigational links" and those links should be relevant to the current page's meaning. But will using this property hurt SEO or make SEO better for each page?

• Serverless Web Application

  - by Andrea Di Persio

  In my company we work on a software that produce reports in html format. My bosses love the fact that static html pages can be moved across computer simply by moving/copying a folder and no web server is involved, so the customer only need a browser. The problem is that they asking me to implement a lot of feature which is very hard to implement properly and in a clean way without an application server. Frames cross domain problem, the impossibility to work with GET and POST data, no URLs routing...is very hard to work with this limitations. Anyone had similiar experience and wants to share their tricks/suggestion ? Do I need to tell my boss 'there is no future without a web server'? Regards.

• Ctrl-Alt-T doesn't open terminal

  - by user204591

  I'm using Ubuntu 13.10 and I've been using for a while now as ran it from a daily build about a month ago. It's fully updated with updates, upgrades an dist-upgrades and it was working up until very recently. Not sure exactly when I last issued a Ctrl+Alt+T as I quite often just leave it running however it will have been certainly in the last week. Basically when I hit that key combo I do not get a terminal. I know that each of the keys function as I can Atl+Tab through open applications and I can Ctrl+C to copy and past Ctrl+V to paste and I've typed plenty here that has a "T" in it. I have checked Keyboard Layout in Settings and the correct combo is assigned to the terminal. You'll have to take my word for that as I'm not allowed to post my screenshot!!!!!

• How can I make a web browser view my .h file as text?

  - by drewbenn

  I want to post a .h file from a project I'm working on. I set a simple href link to it, like: <p>Click here to download the <a href=project_strings.h>strings file</a>. When I click on it, though, my web browser (Iceweasel 12) gives me a prompt to download the file, instead of just displaying it: Is there any magic I can add to the web page, or as a header to the file (that will still allow it to be included by a .c compiled with gcc), to get the .h file to be displayed in the web browser?

• What parts of Java I should know by now?

  - by WinstonChurchill

  I have been working in the enterprise Java field, mostly for financial institutions, for about seven years. Beyond core Java, what are "parts" of Java I should know by now? Should as in it will be useful either to nail the interview, or in an actual job. For example, I have never used JSP beyond "hello, world", but I don't suppose that it's something I need to go learn. But I have got core Spring pretty well done. I've read up on GC but that was a while back and need to re-visit it. I'm looking for one suggestion per post please.

• Dell Latitude D830 DVD Drive Not Recognized

  - by DragonFire

  Unlike some people who have issues with the video or WiFi drivers, I suffer from not being able to use the DVD drive on this laptop. Upon POST, the BIOS sees it and I am able to open the tray as well; however, once the system starts to load up Ubuntu or other distros (Debian and Linux Mint), I lose all functionality. Plus, I don't see it listed as a device in the OS. I've poured over the internet the past few days trying to see if anyone else has the issue, or did and found a solution but sadly, nothing anywhere so far. So, I thought I would ask the community here and see what you all think. Worse case scenario, I have some dead weight to a nice little machine. Thanks! PS I honestly think Linux doesn't like the IDE interface the disc drive has.

• Laptop suspend appears broken, what must I roll back?

  - by M. Tibbits

  Question: What package contains the subprogram responsible for the KMenu option "sleep"? Background: I've been running KUbuntu 10.04.1 and I am completely updated. Recently (within the past month), the "sleep" menu item has stopped working. It just sits there waiting like I clicked nothing. I've check all of the logs in /var/log and nothing is added when I click sleep. I'm guessing that something I updated has bollux'ed things up, but I don't know which package contains the component that I need to roll back. In the meantime, I've installed uswsusp, but s2ram & s2both don't ask my password when the laptop resumes -- which really bothers me. So now that I've got a little time to track this down, I had to post -- any ideas??

  Hello I need help implementing this class https://github.com/sqlboy/tiled-games/tree/master/src into my iOS game. Im using the suggested code of: AStarPathFinder pathFinder = [[AStarPathFinder alloc] initWithTileMap:tileMap collideLayer:@"collide"]; // Optionally, you can set the name of the collide property key and the value it expects. [pathFinder setCollideKey:@"collidable"] // defaults to COLLIDE [pathFinder setCollideValue:@"True"] // defaults to 1 // highlight a path (src and dst are tile coorindates) [pathFinder highlightPathFrom:srcTile to:dstTile]; // move a sprite [pathFinder moveSprite:player from:srcTile to:dstTile atSpeed:0.1f]; I get the following error: Instance method '-initWithTileMap:collideLayer:' not found (return defaults to 'id') This is the official post for the class: http://www.cocos2d-iphone.org/forums/topic/just-pushed-a-cctmxtiledmap-a-pathfinding-class-to-github/ The only other code I added was: #import "AStarPathFinder.h" I think I am perhaps missing something! I am grateful for any help!

• When and How is an image cached for an ASPX with ContentType = image/jpeg ?

  - by Aamir Hasan

   In asp.net you can cache your page. You can vary the output cache by the followingThe query string in an initial request (HTTP GET).Control values passed on postback (HTTP POST values).The HTTP headers passed with a request.The major version number of the browser making the request.      A custom string in the page. In that case, you create custom code in the Global.asax file to specify the page's caching behavior.Link: http://msdn2.microsoft.com/en-us/library/xadzbzd6(VS.80).aspxyou can set the output caching for your GetImage.aspx, so that you dont have to requery the database every image request ,but you must use varybyParam , so that you have a cached version for every parameters arrangement:set the output cache for your page like this :At top of ASPX page: <%@ OutputCache Duration="600" VaryByParam="ID,Height,Width" %>VaryByParam  attribute allows you to vary the cached output depending on the query string.Adding this will make your images cached for 600 seconds, so that if the image request within this period ,the cahed version will be returned

• SQL Why is prefixing column names considered bad practice?

  - by P.Brian.Mackey

  According to a popular SO post is it considered a bad practice to prefix table names. At my company every column is prefixed by a table name. This is difficult for me to read. I'm not sure the reason, but this naming is actually the company standard. I can't stand the naming convention, but I have no documentation to back up my reasoning. All I know is that reading AdventureWorks is much simpler. In this our company DB you will see a table, Person and it might have column name: Person_First_Name or maybe even Person_Person_First_Name (don't ask me why you see person 2x) Why is it considered a bad practice to pre-fix column names? Are underscores considered evil in SQL as well? Note: I own Pro SQL Server 2008 - Relation Database design and implementation. References to that book are welcome.

• Good interview programming projects

  - by bigtang

  I'm looking for some small programming projects that I can give potential employees to gauge their programming abilities. These will be programmers straight out of college. I'm looking for projects that would take someone a couple of hours and they would email back their answers post-interview. One example would be to take this paragraph of text and return a list of alphabetized unique words. After each word tell me how many times the word appeared and in what sentance(s) the word appreared in. Anyone have any good suggestions?
