• Mint 13 no longer using NVidia card after restart

  - by GenericUsrnme

  Here's the story; I bought a new graphics card, along with other parts, about a week ago. I put them in, install new drivers everything's working fine. Now after a restart I boot into some lovely 1024x768 resolution with only one screen on. I check in the NVidia X Server settings to see if my screen was changed there, there's nothing there except Application profiles and nvidia-settings. I check hardinfo to see if the card is actually recognised; VGA compatible controller: NVIDIA Corporation GK106 [GeForce GTX 660] (rev a1) (prog-if 00 [VGA controller]) I don't really know much about the graphics end of things so I'm not sure what I should be doing here to fix this, I don't even know what I should be looking FOR even, so any help is much appreciated! Thanks in advance

• Why does nothing work after I randomly changed some file permissions?

  - by Josh B

  Ok so last night i was trying to set permissions to some folders in my File System, since apparently im not an admin on my own computer. And now everything got messed up today and i don't know what to do.. I lost my internet, the icon is not showing in the taskbar anymore. I lost my sound, there is no sound devices listed when i go into the sound menu. I can not log into root anymore, it gives me "sudo: must be setuid root" I can not plug anything in anymore, it will not recognize flash drives or external hard drives. It gives me a Internal Error message everytime i log in It doesn't let me log into the Grub screen anymore on boot up. What did i do? I have a lot of files on here i wish to put on a flash drive but it won't recognize it.

• Unable to install 11.10 to new OCZ Agility 3 SSD

  - by Masi

  I know the discussion here where they are not getting the same error as I. I use Lenovo Thinkpad X60. The default partition table: sd1 ext4 53.91GB, sd2 extended 1.99GB and sd5 swap 1.99GB. I get Input/output error during read on /dev/sda when trying to install from LiveCD -mode and when trying to install directly. I get the error normally at the stage of choosing time zone or very last at choosing the keyboard layout. Then there is the box with buttons: back, ignore and continue. Neither of them put the process forward so I need to cancel it. How can you install Ubuntu to SDD disk?

• Silverlight 4 + RIA Services - Ready for Business: Consuming Data in the Silverlight Client

  To continue our series, lets see where the fun comes in my look at how easy that is to consume from the client.  First just to help you understand what is happening behind the covers, lets look at a code-behind solution.  In View\Home.xaml put a simple DataGrid on the form. <sdk:DataGrid Name="dataGrid1" Height="152" Width="692" /> Then add these lines of code to Home.xaml.cs   1: var context = new DishViewDomainContext(); 2: this.dataGrid1.ItemsSource...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• When Your ASP.NET MVC Custom Error Doesn't Render...

  You've put [HandleError] on your controller and you've set <customErrors mode="On"> in the web.config file. So why do you still see the yellow screen of death?

• Adsense link units trageting better keywords?

  - by user1010609

  I have one link unit above my navigation which targets exact keywords on what my site is about, on contrary my adsense for content Leadbord and Wide Skyscraper show ads that are totally opposite from my keyword,while my ctr increased for about 10 times with link unit I noticed cpc is lower also (but that was just based on one day, today is higher). Is it so bad to completly get rid of standard content ads and put link units, because this way I earn so little for that site but I think that is because smart pricing (accidental clicks on ads that my users are not interested)? I earn in whole day with about 25-35 clicks as much as keyword tool shows for only one click,my site is first for the topic? I really don't know what to do.. Has anyone had similar situation or can give some advice?

• Grub rescue problem after installing ubuntu

Now the problem. If I remove the external hdd and try to boot windows normally it shows the grub rescue screen. The only way to boot into windows is by having the external hdd attached. Is there any way I can make it so I wont have to have the external hdd attached to be able to boot my windows 7?

• Importance of certifications for Java programmer without BS degree?

  - by programmx10

  I've read some posts here and other places about how a lot of people don't put much value in certifications but I am beginning to think it may be necessary for me at this point to be able to move to a bigger company, etc. I currently work as a Java programmer with a startup and worked with a small company before that. Now that I'm applying with larger companies the hr people / recruiters have been asking a lot about certifications and some have directly suggested that someone in my position should probably get a few (they were trying to be helpful) since I haven't completed a BS degree yet (I bounced around a bit in college and ended up not finishing but have enough units to finish eventually, just its not something I can do nearly as easily as getting certifications). Anyways, just curious about what people think for someone in my situation where I do have an interested in working for large companies and do not currently have a BS degree (but do have experience already in the field). Any advice on which certifications beyond the SCJP would be appreciated as well

• Programming *into* a language vs. writing C code in Ruby

  - by bastibe

  Code Complete states that you should aways code into a language as opposed to code in it. By that, they mean Don't limit your programming thinking only to the concepts that are supported automatically by your language. The best programmers think of what they want to do, and then they assess how to accomplish their objectives with the programming tools at their disposal. (chapter 34.4) Doesn't this lead to using one style of programming in every language out there, regardless of the particular strengths and weaknesses of the language at hand? Or, to put the question in a more answerable format: Would you propose that one should try to encode one's problem as neatly as possible with the particulars of one's language, or should you rather search the most elegant solution overall, even if that means that you need to implement possibly awkward constructs that do not exist natively in one's language?

• robots.txt, how effective is it and how long does it take?

  - by Stefan

  We recently updated the site to a single page site using jQuery to slide between "pages". So we now have only index.php. When you search the company on engines such as Google, you get the site and a listing of its sub pages which now lead to outdated pages. Our plan doesn't allow us to edit the .htaccess and the old pages are .html docs so I cannot use PHP redirects either. So if I put in place a robots.txt telling the engines to not crawl beyond index.php, how effective will this be in preventing/removing crawled sub pages. And rough guess, how long before the search engines would update?

• Multiple Java EE Agents on Single Managed Server

  - by tina.wang

  A default JEE agent is created when you create domain, which is named as OracleDIAgent. 1. In Studio, duplicate the agent, change its name to genAgent, change the web application context to genagent. 2: Go to datasource of genAgent, drop all datasources.3: Generate server template. put the jar file under odi\common\templates\wls 4: Deploy this template by update the existing domain. Bring up the config.cmd, choose update existing domain. 5: Update the domain using the template that just generated. Go through the Configuration wizard. (I did not modify anything or configure anything here). 6: The wizard will give information says the deployment was successful. 7: Bring up the admin server and ODI_server1.

• Open Source: Is Testing/Bug Reporting A Major Contribution?

  - by dsimcha

  When evaluating contributions to open source projects, does testing the code on various real-world inputs, reducing a large number of complicated bugs to small test cases and filing good bug reports count as a significant contribution? I've done this for several open-source projects (specifically D compilers) where I wanted to help out but the codebase was too complicated to learn my way around in the amount of spare time I have. I'm interested in both the perspective of the main developers (those that write the code and fix the bugs) and from the perspective of employers (in case I want to put it on my resume at some point).

• Windows 7/Ubuntu 12 dual boot deleted for Windows 8 installation. How to make grub rescue go away?

  - by dimious

  I had a Windows 7/Ubuntu 12 dual boot and I decided to clean install Windows 8 over them. The problem is that after I deleted all partitions and installed windows I was getting an "Operation system not found", however after an "enter" the system will normally boot into Windows 8. I realized that Windows did their trick and put the system (not partition anymore?!?) "tag" (Disk Management) on my media hard drive. After trying to fix the boot/mbr to be able to boot from my main drive the "Operation system not found" changed to the "grub rescue" prompt. I know that I cannot use that because I have killed the grub files. Windows can still boot as long as I choose to boot from the media drive. The question is, is there any way to move the "system", whatever it is now, to the main drive and have the PC boot from there, while making grub disappear? And if that is possible after that, can I just make the Media drive inactive or I will have to somehow remove the "system" tag?

• Best book for learning C++? [closed]

  Possible Duplicate: Is there a good book to grok C++? I'm lacking a good book for learning C++. Although I'm not an entirely novice, I've learnt C++ mostly by trail-and-error and googling so I don't know all about best practices concerning C++. So what book or books should I get and read? Please only put 1 book per answer, for voting purposes, and maybe a short description of who it's targeted at. Hey, what happened to the community wiki option...?

• Why isn't this simple CRON job working?

  - by JakeRow123

  I am on Ubuntu server and would like to send an email to myself every 10 minutes (as a test). The code for that is in this file: /var/www/cron-test.php To set up the cron I typed: crontab -e and added this line to the bottom of the file using nano editor: ### email me every 10 min. */10 * * * * /var/www/cron-test.php But that script is not running every 10 minutes. I only recieve the email if I load the PHP script directly in my browser. The cron doesn't seem to be executing at all. What am I doing wrong? Also this is my first time setting up a cron so putting the cron script in my www folder is probably not a good idea, should I put it elsewhere? If so where? Also is there a cron error log? Where all failed crons can be seen?

• Advice on how to understand in general and in practice IT Infrastructure

  - by Luca

  My IT knowledge resides mainly in SW development. I have just some basic know how about networks. On the net I tried to get information and read books in order to better understand the overall IT infrastrcuture, but all the sources I found are too generic or, mainly, too detailed in just one aspect, making me lost. Could anyone suggest some books or web resources as good compromise in details? My goal would be able to understand the network issues and security threats when, for example, two remote system have to be setup and put in connection each other. Considering this scenario there are several aspects to consider: firewalls, intranet/internet interconnections, certificates for httpS, etc. The argument is quite wide, therefore I was looking for something that might help to start to understand this subject without going too deep in details (Computer Networks from A.Tanenbaum is a wonderful milestone, but way too specific for my scope). Thanks

• '/'var/www/' vs '/home/$USER/public_html'

  - by OrganizedFellow

  I recently started using Ubuntu as a LAMP server. I've come across plenty of tutorials that say to place the files at '/var/www/' and I've also seen others that put them in '/home/$USER/public_html/'. During my testing and figuring stuff out, I was successfully able to view a test site URL from each location. Is one better than the other? I thought that maybe it was just preference. But the more I think about it, the more I want to keep all my work in my Home folder.

• Identify "non-secure" content IE warns about [on hold]

  - by Doug Harris

  As many know, if you serve a page over https and the content loads resources (images, stylesheets, js, SWF objects, etc) over http, older versions of Internet Explorer will show the user a warning saying "This page contains both secure and non-secure items". This is discomforting to many non-technical users. Usually, I can look at the HTML source and identify which item(s) are triggering this error. Sometimes a Flash object will load something else or some embedded javascript will put a new object in the DOM and trigger this. What tools are good for quickly tracking down the source of the warning?

• Is there any good reason I would want my website to be framed?

  - by minitech

  I'm building a website that's not security-critical in any way at all, so having somebody put a page in an <iframe> is not particularly dangerous to its users. However, as my website doesn't have script plugins that will be used anywhere else, is there any reason why I shouldn't just apply: X-Frame-Options: Deny to every page on my website? Is there any valid reason for any other website to embed mine? I've seen plenty of content-stealing ones and attempts to hijack user accounts, but never an actual good usage of frames that's not an explicit feature of the website.

• Learning the nuances of a language (C++)

  - by prelic

  So I'm a recent college graduate, and I really enjoy working in C++; I worked with it a lot in school, and would like to pursue a career writing in C or C++. The problem I'm having is that I'm trying to learn the nuances of C++. I'm not talking about the basics, or even advanced concepts like templates, namespaces, etc. I'm talking about the real nitty-gritty stuff like undefined behavior and stuff like that. When I'm interviewing, and they put a bizarre piece of C++ code in front of me, and ask me what the output will be, I want to be able to nail those questions. Obviously experience is a great way to learn, but when I write code for practice, I [obviously] know what it does. Reading open-source projects have been good practice, but I find that there tends to be an enormous learning curve just understanding the organization of the code (because the projects tend to be large). So basically what I'm asking is, what should I do now?

• How do I get my RTL8192ce based wireless device working properly?

  - by JonnyTruelove

  I am using the rtl8192cu chipset (on a Belkin wireless USB adapter N300) combined with 64 bit architecture and the 3.8 kernel. Some of you may know that this doesn't work. I tried this fix - RTL8188CU USB Network Adaptor on ubuntu 13.04 and now my internet is super slow. I am totally new to Ubuntu and I am concerned I do not have the right driver. The "stock" driver was the RTL8192cu, but it didn't connect 99% of the time and if it did the upload speed was higher than the download. Right now I am connecting through my laptop with a crossover cable, so my internet connection is just fine in my apartment. Relevant output from lsusb is here: Bus 002 Device 002: ID 050d:2103 Belkin Components F7D2102 802.11n N300 Micro Wireless Adapter v3000 [Realtek RTL8192CU] (bonus question: is that [050d:2103] the actual physical address straight from the hardware? Or does it change when I put different drivers on it? I am concerned I do not have the right driver)
