• Connection manager detects network but won't connect

  - by Carson Chittom

  I've just installed 12.04 on my home desktop. Because of where it's located, in order not to have my children tripping over cat5 cable, I've got a cheap 802.11n USB device plugged in, which uses a Realtek 8192CU chip. The house wifi is protected with WPA2. Ubuntu's Network Manager detects the network, but connecting to it just times out and asks for the password again. I'm sure I'm using the correct password. No other computers on the house network are having any difficulty. This device previously worked correctly with both Windows 7 and OpenBSD in the same machine. The linux-firmware package is installed (from the disc) at version 1.79, and /lib/firmware/rtlwifi/rtl8192cufw.bin is present. dmesg|grep rtl only shows the "loading firmware" message. I've tried Google, but I apparently can't find the right set of words to plug in, because I haven't found anything related (lots of "doesn't work at all," but nothing matching my circumstances). Any help would be greatly appreciated.

• Unity Occlusion Portals: What and How?

  - by Nick Wiggill

  (Here I eat my words on Meta about posting Unity questions on Unity Answers... since that site is less responsive than this one.) Unity provides cell-based Occlusion Culling (via Umbra, I believe). However, a newer feature that it supports is Occlusion Portals. The question is, if BSP-based occlusion culling is already a feature of Unity, what do portals add, and how? PS. This question is not "What are portals?" -- I'm aware of the original Quake BSP-style portals -- which is partly why I find the explicit portal concept in Unity odd, since it uses BSP anyway.

• Does 3d modeling software *choice used during asset creation affect performance at runtime

  - by user134143

  Does software used to create 3d assets (for game development specifically) have an impact on the efficiency of the program. In other words. Is it possible to reduce the operating footprint of an application merely by utilizing alternative development software during production of 3d assets. If you use two different applications to create a 3 dimensional image of a box, can one of them result in better performance if aspects of the image are identical? Sorry if this question seems vague, I am attempting to get the information I need without causing unnecessary debate over specific software choice. Thank you.

• 2D shader to draw representation of rotating sphere.

  - by TheBigO

  I want to display a 3D textured sphere, and then rotate it in one direction. The direction will never change, and the camera will never move. One way is to actually create a spherical mesh, map a texture to it, rotate the sphere, and render in 3D. My question is, is there a way to display a 2D circle, that looks like a rotating sphere, with just a 2D shader. In other words, can someone think of a trick, like mapping a texture to the circle in a particular way, to give the appearance of an in-place rotating sphere, that is always viewed from the side? I don't need exact shader code, I'm just looking for the right idea.

• A simple message room

  - by webbyJoe

  Can anyone recommend a simple message room (not chat room) which I can use for a private communication between my users. My idea: to grant some users (2-3 at the most) a specific privilege to talk privately in a message room. none of them would be administrator there. I need such features: - admin panel for adding users allowed to post messages in room - room invisible to anyone except users - filtering not-allowed words - Ajax-enabled so that replies appear immediately - other message room features I have a linux hosting so PHP message room would be the best option. I thought of using a forum for this, but it's too much work as a forum is public by nature and I need something private by nature. Any ideas? Thanks in advance.

• Developing Salesforce apps in Ruby on Rails

  - by Robert S.

  I want to build a web app that uses Salesforce.com data, and I want to build it fast. I'm a .NET developer (WPF, C#, ASP.NET MVC). I understand Ruby and RoR fairly well, but I haven't delivered any Rails apps. I'm wondering, is Ruby on Rails a suitable tool for rapidly building Salesforce apps, or is it better for the "traditional" web2.0 stuff like Groupon and Twitter? In other words, would using RoR help me achieve my fast (e.g., three months) goal over using .NET, which I already know?

• git in non-distributed, independent, lone programming ...best practice(s) ?

  - by explorest

  I am currently studying the git documentation to get a hang of distributed version control workflow and use of git command line. I want to first start using git with small, personal, pet projects so to gain experience before doing it on large scale (i.e., bigger projects, team dev). What areas of the git system should I, as a lone player, devote most of my study time to... what parts should I leave for the larger scale work later on. In other words what features of the git system will fully be grasped in team work only, and therefore should not be too involved with at an individual level?

• Did You Know: What do you know that isn't so?

  - by Kalen Delaney

  You know what they say… it's not what you don't know that will hurt you, it's what you know that isn't so! In other words, your misconceptions. Or, as Paul Nielson calls them in his SQL Server Bible … MYTHconceptions. Some misconceptions come from misunderstanding of complex information, or from misinterpreting your own results, and assuming we can generalize behavior from one particular situation. Since I teach advanced classes to students with lots of SQL Server experience, I actually see a lot...(read more)

• AdSense Custom Search Ads - custom quesry

  - by Alex

  i'm trying to set up a custom search ad, but I am nost sure about the query. On the site it says (https://developers.google.com/custom-search-ads/docs/implementation-guide) 'query' should be dynamic based on your page. This variable targets the ads and therefore should always match what the user on your site has just performed a search for. Now, what I understand is: I have to program my page so that the query variable contains some custom words. Am I right? If a user gets to my site through clicking on an adsense, there is no way to "know" what the user looked for and display my query accordingly, right? Thanks for any help!

• Using disqus for a website (question on SERP and backlink)

  - by Homunculus Reticulli

  I am building a website and am trying to decide between writing my own commenting system and using disquss. One of the main deciding factors is that (obviously), I want comments left on my page to be show on SERPS. However, I remeber reading somewhere that disqus loads comments into a page using AJAX - and therefore the comments are "invisible" as far as Googlebot and other SE crawlers are concerned. Could someone confirm or refute this? The other question I have is about whether (as a commenter), When I place a comment on another website using disqus (including any links I may add to my comment), do the lionks in my comment count as a backlink (in other words are they "dofollow" or "nofollow" links)?

• Job Search Engine Url Structure Issue [closed]

  - by Justin

  Possible Duplicate: What is the best stucture of SEO friendly URL? I am working on a job board, and i'm trying to figure out a good design for URL structure. Some things that I have found through research: 100 - 150 Chars long is ideal 3-5 words in your url, according to Matt Cutts Use .htaccess to force clean urls Do not duplicate data (important) Clean and precise, describing the content Use hyphens On the homepage, I try to detect the users location based on IP, but this isn't always accurate, and not always reliable. So until they put in their city/location, I can't always use this structure but this is potentially work-able. For Searching, a form post to a results page: domain.com/jobs/[city]/[search] ie: domain.com/jobs/toronto/sales manager/ OR domain.com/search/jobs/toronto/sales manager/ or do I remove the word JOBS and just use Search. I trying to keep good search terms in the URL, but also keep it clean and concise. Can someone give me some feedback and thoughts to 'why'...

• Samsung 700Z broken by Precise install

  - by Eric

  I tried to install Precise from DVD media and got to the point where the Ubuntu logo is on screen indicating the the installer is loading. At that point the screen went dark. After some time I rebooted the machine. To my dismay the machine would no longer start (Powers on but but no bios start up screen, I can hear initial hard drive spin which soon dies). This is a new machine (less than 2 months) and I have had no previous indications of defects before this incident. In other words, I am convinced the Ubuntu install had something to do with the failure of the machine. Has anyone else had this problem with this model machine? Is this known to happen with precise or other versions of Ubuntu?

• Is there a weight for html link?

  - by Questions

  I would like to know if there is any weight associated with a html link (its backlink) when google does crawling/indexing. Will 1,2 & 3 be ever considered as a backlink by Google? 1. <a href="xyz.com">1</a> // one character link 2. <a href="xyz.com"> </a> //blank space link 3. <a href="xyz.com">!</a> //special character link 4. <a href="xyz.com">keyword</a> //meaningful word link I hope my question is understandable and guess this is right forum. I don't know to put it in other words. Thanks in advance.

• Q&amp;A: Will my favourite ORM Foo work with SQL Azure?

  - by Eric Nelson

  short answer: Quite probably, as SQL Azure is very similar to SQL Server longer answer: Object Relational Mappers (ORMs) that work with SQL Server are likely but not guaranteed to work with SQL Azure. The differences between the RDBMS versions are small – but may cause problems, for example in tools used to create the mapping between objects and tables or in generated SQL from the ORM which expects “certain things” :-) More specifically: ADO.NET Entity Framework / LINQ to Entities can be used with SQL Azure, but the Visual Studio designer does not currently work. You will need to point the designer at a version of your database running of SQL Server to create the mapping, then change the connection details to run against SQL Azure. LINQ to SQL has similar issues to ADO.NET Entity Framework above NHibernate can be used against SQL Azure DevExpress XPO supports SQL Azure from version 9.3 DataObjects.Net supports SQL Azure Open Access from Telerik works “seamlessly”  - their words not mine :-) The list above is by no means comprehensive – please leave a comment with details of other ORMs that work (or do not work) with SQL Azure.

• Samba network sharing NTFS drives and root permissions from local drives

  - by Bill

  I'm able to share my internal 2ndry NTFS drives (sdb1,2 and 3) on the network with Windows computers now but even though Samba read/write is enabled, Windows network computers can only open files "read-only" and can't save files to the samba shared drives/folders. I try to set permissions in Ubuntu via folder and/or file properties even logged in root via Nautilus but all the samba shared folders and files are set as owner = root, accessible and does not allow me to change them to read/write, it just resets to root, accessible, in other words, I can't change permissions. I'm running Ubuntu 11.04 Gnome on an old Dell Dimension 2400. Also, in order to for me to copy or move any files from the Ubuntu drive to the sdb1,2 or 3 drives, I have to gksu nautilus. This consequently prevents me from copying .ISO files to my "Multisys" thumb drive too.

• Will Tracking Subdomains as Single Entity with Google Analytics Help SEO? [closed]

  - by Sam Gridley

  Possible Duplicate: Does Google Analytics data affect SEO? We have two subdomains, one for our blog and one for our ecommerce store. The blog serves to bring traffic and the store is how we monetize the site. We have them designed to appear as one large site, but I know google sees them as two sites. Here is how the subdomains look: www.example.com (store) blog.example.com (blog) I believe I can configure analytics to use subdomain tracking as explained here: http://support.google.com/googleanalytics/bin/answer.py?hl=en&answer=55524 But my question is whether this will cause google to see our 2 subdomains as one larger domain for SEO purposes. In other words, is there any relationship to how you configure google analytics and how google indexes and ranks your website(s) and pages? Is there anything I need to do in anaytics or webmaster tools to make google aware that these two subdomains work together as one website? Thanks! Sam

• mismatch of version of libkdcraw20 and libkdcraw-data

  - by naveen jankar

  I'm using Ubuntu 12.04 LTS. When I'm installlin digiKam, I'm getting a mismatch in the versions of libkdcraw20 and libkdcraw-data wanted by it and that available in the repositories. It wants version 4.8.5-0ubuntu0.2 (or in other words that is the latest version according to synaptic) but the available one is 4.8.5-0ubuntu0.3 in both cases. Is there a work-around? Or how do I request the Ubuntu managers to rectify this? addenda On Synaptic i selected digikam to be installed. it downloaded all the dependencies but the 2 in question were not found - the message it gave "W: Failed to fetch security.ubuntu.com/ubuntu/pool/main/libk/libkdcraw/… 404 Not Found [IP: 91.189.91.13 80]". I google-searched the 2 files in the repositories to find that the version available there is ubuntu0.3 instead of ubuntu0.2.

• Is it time to add IPv6 access to my websites?

  - by Rob Hoare

  I have several dedicated servers and VPS servers, and some of those are at companies that have provided me with native IPv6 blocks (in addition to the IPv4 IP addresses). Does it currently make sense to point an AAAA record to an IPv6 address on my server, in addition to the A record pointing to the IPv4 address? This would be for (for example) the www subdomain. (the networking and web server software would be set up on the server to respond appropriately). A while ago I read that a small percentage of users (1 in a thousand?) would have slow or no access if a subdomain had both A and AAAA records because their networking software asked for one and got the other. Is that still the case, will adding an AAAA record inconvenience some users, or is the percentage already smaller and falling? In other words, is now the time to get around to adding native IPv6 support for a busy website aimed at the general public, or is it still too early?

• Application use on website

  - by Palmer

  Is there a good way to run a C# application on clientside in lieu of JavaScript? I have done some front end work with JavaScript and backend C# for web developing at an old job, but I am interested in hosting a website myself soon. I have a C# application I would like to be open source, but before people care to download I'd like them to be able to use it. At its basic level it's a simple text editor, but there's much more to it in the nitty gritty. I could write it in JavaScript, but it would require me to keep documentation and up to date changes on JavaScript and C# in that case. I was thinking of creating an AJAX panel and somehow loading my winform application into a frame, but I don't know how or what words to google because I've never done it before except AJAX.

• How do I improve my problem-solving ability

  - by gcc

  How can I improve my problem-solving ability? Every one says same thing "a real programmer knows how to handle real problem", but they forget how they learn this ability, or where (I know in school, no one gives us any ability, of course in my opinion). If you have any idea except above ones, feel free when you give your advice solve more problems do more exercises, write code, search google then write more ... For me, my question is like "Use complex/known library instead of using your own." In other words, I want your experience, book recommendation, web page on problem solving

• How do I improve my ability to manipulate code quickly, not wpm?

  - by Steve Moser

  I have seen several questions on here about touch typing and words per minute but not about improving ones ability to manipulate text using keyboard shortcuts, bindings etc. I have tried putting a cheat sheet of keyboard shortcuts next to my monitor but I can never incorporate them in my 'flow'. I have also tried the 'just use vi and don't touch the mouse' method but that only helps me with navigating code and not editing. I would prefer to use some application (or game) to learn text manipulation. But it looks like nothing like that exists (app idea?). I'm open to other suggestions too.
