• How do I reset my Ubuntu user password?

  - by Myself

  I lost my Ubuntu user account password... I saw some other questions on this topic that had answers telling me to restart the computer, press the left shift key after BIOS, go to root, type "passwd [username]" and all this other stuff, but none of that worked. After I typed a new password and retyped it, it gave me an error message saying something like "Authentication Manipulation Error." There was another question complaining about this, but there weren't any useful answers that worked. Does anybody know of a way for me to retrieve or reset my password? Am I doing something wrong with that method I mentioned?

• Selling your iphone games.

  - by Artemix

  Hi. So, long story short, some days ago I pusblished an iPhone game, I think the game wasnt that bad tbh, and still I got only 10 sells at $0.99. Are they any publishers, sponsors, or distributors to make your game "visible" on the app store market?, or the only thing you need is to have an amazing game and thats all? Somehow I think that even if you have an awesome game if you dont do that "marketing magic" correctly you will not exist in the store. Now Im making a second game, completly different, and I want to know how to do things right. If anyone knows something about this topic, let me know. Thx in advance.

• How to spot a good social media marketer

  - by fiftyeight

  It's a bit subjective but helpful and on-topic IMO, mayebe should be made community wiki I've been in contact with some guest bloggers lately which are interested in publishing posts on my website's blog, so far I've done a regular weekly blog and had a guy marketing it, but he's too busy to do more work right now. Now I need someone to market these blog posts on social media, the last guy I just got by recommendation from a friend, but now I need to find one myself. What criteria should I check when it comes to social media marketers? Do the number of followers and fans on their accounts and/or the number of votes they get for articles they market mean anything, or is impossible to know if it's spam? That's about the only criterion I could think of so far... Thanx to anyone who helps

• Designing a simple snake A.I

  - by DillPixel

  I've looked at some stuff online regarding this specific topic, and a lot of the info that I read involved graphs and path finding. I really don't want to get involved in something too complex & out of my level, and also I don't need my snake to be that intelligent (it will be a large board with the snake not growing in size on every munch). How could you structure a simpler AI for the snake that gets the job done relatively well? I would be able to get the snake to move towards the food item correctly, but my issue is that I'm not sure how to deal with the snake colliding with itself. Say the snake has a look ahead, and it finds that its tail is in the way, it could change direction, but what happens next? Any ideas on how to tackle this? Should the snake build an instruction set from every square, or should it think on the go?

• Switching to WIF SessionMode in ASP.NET

  - by Your DisplayName here!

  To make it short: to switch to SessionMode (cache to server) in ASP.NET, you need to handle an event and set a property. Sounds easy – but you need to set it in the right place. The most popular blog post about this topic is from Vittorio. He advises to set IsSessionMode in WSFederationAuthenticationModule_SessionSecurityTokenCreated. Now there were some open questions on forum, like this one. So I decided to try it myself – and indeed it didn’t work for me as well. So I digged a little deeper, and after some trial and error I found the right place (in global.asax): void WSFederationAuthenticationModule_SecurityTokenValidated( object sender, SecurityTokenValidatedEventArgs e) {     FederatedAuthentication.SessionAuthenticationModule.IsSessionMode = true; } Not sure if anything has changed since Vittorio’s post – but this worked for me. While playing around, I also wrote a little diagnostics tool that allows you to look into the session cookie (for educational purposes). Will post that soon. HTH

• RabbitVCS suddenly stopped working in Nautilus with Ubuntu 11.04

  - by Sander

  A while ago I installed RabbitVCS on Ubuntu 11.04. It then all worked pretty well, but since a few weeks (maybe even more than a month) RabbitVCS suddenly disappeared from the Nautilus context menu. I visited this page: http://wiki.rabbitvcs.org/wiki/support/known-issues and saw some points I could try, but none of them worked out to a working version again. Also this issue Rabbit VCS stopped working after upgrade to 11.10 does not describe the solution for me, so I think it might be something else. I have also tried to reinstall RabbitVCS again from the PPA which was recently updated according to this topic, but no luck. I am still on 11.04 (as I don't like the way Ubuntu is going in newer versions at all) and my Nautilus version is 2.32.2.1 . Is there someone who can help with this one?

• How to improve quality of software

  - by hariharan

  Last week in our organization, we triggered a topic related to different ways of improving the quality of software (both technical as well as functional related topics). Since i am a technical person, i suggested following ideas, Use case based detailed design document – Both technical as well as functional specification should be well organized according to use case requirement. Design patterns – Will help developers to adopt common approach irrespective of technologies. Analyze and implement new technologies – Helps to improve the performance as well as the security of the application. As I am not a well experienced technical candidate , i am unable to provide other solutions. If any suggestions or topics related to this (including testing, functional requirement), please post your valuable comments.

• More confusion over SEO Cname and 301 redirect

  - by Alasdair

  Previous answers on this topic don't really help me with my query, so any help appreciated for a bit of a newbie. I have a new domain "domain#1.mobi" Its hosted with godaddy and has a cname and forwarding, pointing it to "domain#1.elsewhere.us" It has no content. The content is all hosted on "domain#1.elsewhere.us" which is what Google is now listing in its results. I want Google to ignore that and only list "domain#1.mobi" in its listings. How do I achieve this?

• Creating date based back entries for a blog and its site registration

  - by open_sourse

  So I am showing a blog to a colleague and telling him how the author has been regularly blogging for over ten years now. My colleague tells me that anyone can register a domain name and start entries from say circa 2000. When I argued that the site registration date can easily show that the registration was done recently he put forward two arguments: The author can claim that he moved from an old domain name which was registered many years ago and lapsed. So he took the data and rebuilt it in the new site. The author can buy an expired domain which was on the internet for many years. I am not sure if these ways can work to con someone to believing you have been a blogger for over a decade. But I do not have enough expertise in the topic to refute him. So I thought I would ask the wise community here at StackExchange. Can anyone give me some insight?

• My page no longer shows up in Google's results for a keyword

  - by user6456

  I have a small website about a commercial product, with a description and tutorial. 2 days ago it was in position 11th in Google search results, without any kind of SEO optimization on my part. Today it's gone. Totally gone - not even in the first 200 results. It's still very high in bing.com and duckduckgo.com. The site is very on topic. It's hosted under domain Keyword.com, and it's about commercial product which addresses the Keyword. How can I know what happened?

• Do delegates defy OOP

  - by Dave Rook

  I'm trying to understand OOP so I can write better OOP code and one thing which keeps coming up is this concept of a delegate (using .NET). I could have an object, which is totally self contained (encapsulated); it knows nothing of the outside world... but then I attach a delegate to it. In my head, this is still quite well separated as the delegate only knows what to reference, but this by itself means it has to know about something else outside it's world! That a method exists within another class! Have I got myself it total muddle here, or is this a grey area, or is this actually down to interpretation (and if so, sorry as that will be off topic I'm sure). My question is, do delegates defy/muddy the OOP pattern?

• Making a collision detection system

  - by Sri Harsha Chilakapati

  I'm very new to game development (just started 3 months ago) and I've learning through creating a game engine. It's located here. In terms of collision, I know only brutefoce detection, in which case, the game slows down if there are a number of objects. So my question is How should I program the collisions? I want them to happen automatically for every object and call the object's collision(GObject other) method on each collision. Are there any new algorithms which can make this fast? If so, can anybody6 sh6ed some light on this topic? And I think of making it like the game maker Thanks

• navigation menus and SEO

  - by Rodolfo

  I've always have my doubts about navigation menus effect on SEO. You know, the vertical menus on the top that show in every page in the site linking to main sections and subsections. My issue is that if not done dynamically (i.e. after page is loaded or something), from a search engine's point of view it probably looks like a whole bunch of links in the beginning of the page, and links that probably have nothing to do with the page being analyzed, so it's probably not only confusing it, but also giving link 'juice' to the wrong pages or reducing its value. When I've asked SEO people about this, I usually get a "Google is smart, they'll recognize it as a menu and ignore it" response, but I'm not convinced (and the 'Google is smart' argument sounds almost like religion discussion to me). So does it affect SEO negatively or not? Are there any official posts on this topic?

• What should you include in a development approach document?

  - by Liggy

  I'm in the middle of co-producing a "development approach" document for off-shore resources as they ramp up onto our project. The most recent (similar) document our company has used is over 80 pages, and that does not include coding standards/conventions documents. My concern is that this document will not be consumable and will therefore fail. What should be in a development approach document? Are there any decent guidelines on this topic? EDIT: The development approach document should detail the practices and techniques that will be used by software developers while software is designed, built, and tested.

• Caching strategies - LRU, MRU, Clock-Pro

  - by golgofa

  I am going to write a bachelor's science work on caching strategies and really, can't find any links to specifications or full descriptions of some of them. Only something like summaries from wikipedia. Please, help with some links on LRU, MRU caching and new-one - Clock Pro. Thanks a lot. All links are very useful for me. The purpose of work - is to compare different cache strategies to get more effiency. It based on WebApplication with ejb 2.0, so algorithm's will be implemented there, espesially in ejbLoad() and ejbFindByPrimarKey(). Also, one of aspects of this application - it will use not common scheme of tables in database - it based on metamodel. So, if you had any experience on this topic, i would be grateful to take some of your knowledge)

• Is there any research about daily differences in productivity by the same programmer?

  - by Rice Flour Cookies

  There has been a flurry of activity on the internet discussing a huge difference between the productivity of the best programmers versus the productivity of the worst. Here's a typical Google result when researching this topic: http://www.devtopics.com/programmer-productivity-the-tenfinity-factor/ I've been wondering if there has been any research or serious discussion about differences in day-to-day productivity by the same programmer. I think that personally, there is a huge variance in how much I can get done on a day by day basis, so I was wondering if anyone else feels the same way or has done any research.

• How to remove options from right click menu?

  - by Someone Like You

  There was this question, which suggest the use of Nautilus actions So i installed that. I try to open it but it does not open. I'm not asking you to fix it since Ask Ubuntu is not a bug tracker. All bug reports here will be closed as off-topic Fair enough, and i don't have time to report bugs, anyway Nautilus actions doesn't seem to care about the bug, it was reported before no actions were taken. Thus I don't seem to care about Nautilus actions. My question is simple: I want to know is there any alternative to Nautilus actions, or even better, how to add/remove options from the right click menu manually (without using any other software).

• Choice of Operating System Version for Azure Roles

  - by kaleidoscope

  Customers can now choose when their applications receive new operating system updates and patches by selecting which version of the operating system their applications will run on in Windows Azure.  Right now there is only one available operating system version (released on December 17th, 2009), but new builds with the latest updates and patches will be released regularly.  This new feature allows developers to test their applications when new patches come out before upgrading their production deployments. To select an operating system version for your application, add the new osVersion attribute to your service configuration file.  The full list of available operating system versions is maintained in the Configuring Operating System Versions topic in the Windows Azure MSDN documentation.   Sarang, K

• SSIS 2008 Configuration Settings Handling Logic for Variables Visualized

  - by Compudicted

  There are many articles discussing the specifics of how the configuration settings are applied including the differences between SSIS 2005 and 2008 version implementations, however this topic keeps resurfacing on MSDN’s SSIS Forum. I thought it could be useful to cover the logic aspect visually. Below is a diagram explaining the basic flow of a variable setting for a case when no parent package is involved.   As you can see the run time stage ignores any command line flags for variables already set in the config file, I realize this is not stressed enough in many publications. Besides, another interesting fact is that the command line dtexec tool is case sensitive for the portion following the package keyword, I mean if you specify your flag to set a new value for a variable like dtexec /f Package.dtsx -set \package.variables[varPkgMyDate].value;02/01/2011 (notice the lover case v in .value) You will get errors. By capitalizing the keyword the package runs successfully.
