• Why is my display name in Ubuntu Software Center some weird set of letters?

  - by Ike

  In USC, after I submit a review, my display name is "Bnxdcty"... a swell name, but where did it come from? I have checked the ubuntu single sign on page, verified my nickname on there, changed it to something else and back again for good measure, but still my reviewer name is somehow still "Bnxdcty". I even unauthorized ubuntu software center and then re-opened it/authorized it to my account. Does this just appear as this to me and others see my correct user nickname? It doesn't bother as much as it confuses me. I just know it will be something stupid that everyone knows but me.

• Page for Page Redirect in Google App Engine

  - by clifgray

  I have recently changed domain name for a webapp I run on Google App Engine and I am wondering if there is a simple way to do a page for page redirect from my old website to the new domain. Everything code wise is staying exactly the same but I just want it to go to the new domain. I am using python and the webapp2 framework for the webapp. I know I could go through and for every single handler do: webapp2.redirect('the specific url', permanent=True) But I am hoping for a simpler solution.

• Git bug branching convention

  - by kisplit

  I've been following the successful Git branching model guide for most of my development. I still wonder if the way I handle bug tickets is correct. My current workflow: Once I accept a bug ticket I will do a git checkout -b bug/{ticket_number}, create a single commit as a fix and then checkout develop and do a git merge --no-ff. I'd love to hear from the experiences of others whether or not I am abusing the --no-ff option in this instance. If I am, could someone suggest a better approach?

• How to avoid being forked into oblivion by a more powerful contributor?

  - by Den

  As recently reported here: Xamarin has forked Cocos2D-XNA, a 2D/3D game development framework, creating a cross-platform library that can be included in PCL projects. However the founder of the project that was forked says: The purpose of the MIT license is to unencumber your fair use. Not to encourage you to take software, rebrand it as your own, and then "take it in a new direction" as you say. While not illegal, it is unethical. It seems that the GitHub page of the new project doesn't even indicate that it's a fork in a typical GitHub manner, opting for an easily-removable History section instead (see bottom). So my questions are: Was Xamarin's action and the way the action was done ethical or not? Is it possible to avoid such a situation if you are a single developer or a small unfunded group of developers? I am hoping this could be either a wiki question or there will be some objective answers grounded on modern OSS ethics/philosophy.

• How much to charge for Wordpress installation?

  - by Jack Duluoz

  I know this isn't properly a technical question but I hope this is ok here. The question is simple: how much should I charge a customer for a Wordpress installation & configuration? Configuration simply means I have to install him a theme (which is not provided by me), various plugins and maybe edit some lines of code here and there to make the whole thing work fine. MORE INFO I don't do this for a living, I'm just doing this for this single customer. He told me he wants to customize some features of the blog which I think will require a bit of code editing, but these will be small modifications, because I already told him that more substantial modifications will be billed separately. I don't know exactly how long will this take, but probably just 1 day for the setup and some more days to adapt the blog to the customer requests which will eventually come up later

• Defining the track in a 2D racing game

  - by Ivan

  I am designing a top-down racing game using canvas (html5) which takes a lot of inspiration from Micro Machines. In MM, cars can move off the track, but they are reset/destroyed if they go too far. My maths knowledge isn't great, so I'm finding it hard to separate 3D/complex concepts from those which are directly relevant to my situation. For example, I have seen "splines" mentioned, is this something I should read up on or is that overkill for a 2D game? Could I use a single path which defines the centre of the track and check a car's distance from this line? A second path might be required as a "racing line" for AI. Any advice on methods/techniques/terms to read up on would be greatly appreciated.

• How are crossplatform/multiple-OS C++ projects planned in terms of code and tools?

  - by Nav

  I want to create a project in C++ that can work in Windows, Linux and Embedded Linux. How are projects created when they have to work across many OS'es? Is it first created on one OS and then the code slowly modified to be ported to another OS? Eg: to me, the Linux version of Firefox appears to be created as a Windows project and a separate Linux project with a different code base, since Firefox behaves a bit different in Windows and Linux. Although the source code download is surprisingly a single link. If QT is used for UI, Boost threads for threading, Build Bot for CI and NetBeans/Eclipse/QT Creator for an IDE, would a person be able to minimise the amount of code re-write required to get the project onto another OS? Is this the right way to do it, or are such projects meant to be created as two entirely separate projects for two separate OS'es?

• Problems installing 13.10 inside VMWare Player 4

  - by Thomas S.

  In the past I had no problems installing Ubuntu 12.04 inside VMWare Player 4.0.4 on my Windows 7 Pro machine. Now I installed Ubuntu 13.10 and have a couple of problems: the default screensize (even during the installation) is gigantic I've told Ubuntu to automatically login - after reboot the gigantic screen occurs without showing anything, without doing anything on mouse clicks, Ctrl+Alt+Backspace does not work switching to console using Ctrl+Alt+F1...F6 works, but is incredible slow invoking 'sudo reboot now' does not succeed, it prints Killing all remining processes... [fail] Restoring resolver state... [ OK ] Will now switch to single-user mode root@ubuntu1310:~# invoking now 'shutdown now' will soon show the same error. What I need to do to get Ubuntu 13.10 up and running in VMWare Player?

• How can you predict the time it will take for two processes in two different machines in a cluster to communicate?

  - by Dokkat

  I am trying to develop a computing application which needs a lot of memory (500gb). Buying a single machine for that is overly expensive. I can, though, buy ~100 small instances on Digital Ocean or similar, divide the memory in blocks and use TCP to emulate shared memory between the instances. Now, my question is: how can I measure/predict the time it will take for two processes in two different machines like that to share information, in comparison to IPC and shared memory? Are there rules of thumb? I don't want exact values, but knowing more or less how much faster one is would be very helpful in visualising the feasibility of this approach.

• Using glReadBuffer/glReadPixels returns black image instead of the actual image only on Intel cards

  - by cloudraven

  I have this piece of code glReadBuffer( GL_FRONT ); glReadPixels( 0, 0, width, height, GL_RGB, GL_UNSIGNED_BYTE, buffer ); Which works just perfectly in all the Nvidia and AMD GPUs I have tried, but it fails in almost every single Intel built-in video that I have tried. It actually works in a very old 945GME, but fails in all the others. Instead of getting a screenshot I am actually getting a black screen. If it helps, I am working with the Doom3 Engine, and that code is derived from the built-in screen capture code. By the way, even with the original game I cannot do screen capture on those intel devices anyway. My guess is that they are not implementing the standard correctly or something. Is there a workaround for this?

• How can I resize an external USB NTFS partition?

  - by chris

  I have a new USB drive which came with a single NTFS partition. How can I shrink that so that I can create an ext4 partition? gparted does not seem to have the "Resize" option highlighted. Update: After following the directions below, after unmounting I am still not able to resize the partition. There is a warning though: "Unable to find mount point. Unable to read the contents of this file system! Because of this, some operations may be unavailable. The following list of software packages is required for ntfs file system support: ntfsprogs". However, with the partition mounted, I can read & write to the file system on the drive just fine, and ntfsprogs is installed and current. What's next?

• Find Nearest Object

  - by ultifinitus

  I have a fairly sizable game engine created, and I'm adding some needed features, such as this, how do I find the nearest object from a list of points? In this case, I could simply use the Pythagorean theorem to find the distance, and check the results. I know I can't simply add x and y, because that's the distance to the object, if you only took right angle turns. However I'm wondering if there's something else I could do? I also have a collision system, where essentially I turn objects into smaller objects on a smaller grid, kind of like a minimap, and only if objects exist in the same gridspace do I check for collisions, I could do the same thing, only make the gridspace larger to check for closeness. (rather than checking every. single. object) however that would take additional setup in my base class and clutter up the already cluttered object. TL;DR Question: Is there something efficient and accurate that I can use to detect which object is closest, based on a list of points and sizes?

• How can a collection class instantiate many objects with one database call?

  - by Buttle Butkus

  I have a baseClass where I do not want public setters. I have a load($id) method that will retrieve the data for that object from the db. I have been using static class methods like getBy($property,$values) to return multiple class objects using a single database call. But some people say that static methods are not OOP. So now I'm trying to create a baseClassCollection that can do the same thing. But it can't, because it cannot access protected setters. I don't want everyone to be able to set the object's data. But it seems that it is an all-or-nothing proposition. I cannot give just the collection class access to the setters. I've seen a solution using debug_backtrace() but that seems inelegant. I'm moving toward just making the setters public. Are there any other solutions? Or should I even be looking for other solutions?

• Windows Server - share files without access for administrator

  - by Pawel

  We have a MS Windows Server 2008 R8 based server that is administrated by our IT department. We would like to achieve two things simultaneously: A folder on the server, containing several thousand files (new files added frequently) that is accessible to some ActiveDirectory users (e.g. board of directors) but is not accessible by IT department employees IT department employees still maintain rights to administrate the server, including installing new software and services We already checked some solutions: Using NTFS access rights. Unfortunately IT (members of "Administrators" group) can set themselves as new owners of the files and change the permissions so that they gain access to the files. Enabling EFS. Unfortunately even if you do not allow IT to access files, they still can disable EFS completely because they have administrative rights. Moreover as far as I know you have to manually add permissions for all users but the owner for each new file - very inconvenient. Creating a new role for the IT department that has all the privileges apart from taking ownership of files. Unfortunately if you're not a member of the Administrators group, you cannot install new software, no matter what privileges you add to the role. TrueCrypt - nice free encryption software, but with poor sharing capabilities. You can either mount an encryption container on the server (and then IT has access to its contents) or you mount them locally but only one user can mount it for writing. AxCrypt - free encryption software that enables file-by-file encryption on the server. There are some disadvantages though - you have to manually encrypt each new file added. The files have their extensions changes. You can only set one password for all files (so all users have to know this one password). Any other ideas? Our budget is limited so enterprise-class software from Symantec or PGP would probably be not an option.

• Design leaderboard ratings for quiz games

  - by PeterK

  Back in March 2011 i started the following post: How to design a leaderboard? Now my quiz game have been out for approximately a year and sold pretty decently. I am working on to update the game design and is again looking into the leaderboard design to make it better as i am not happy with it. Currently i rate players on number of correct answers, which is not good as it does not consider things like number of games, difficulty levels etc. I also have "extended" stats behind the UITableView (Leaderboard). A player can play based on three levels of difficulty: hard, medium or easy Difficulty levels can be mixed between players in a game Each game can be one to six players, so there can be single games or duels Between 2 and 30 questions per game As i am considering integrating Game Center Leaderboard i need to design a better rating system so i would like to ask for some ideas how to do the rating based on the above. I am thinking about how much a point would be worth and what it includes.

• How to prevent code from leaking outside work?

  - by AeroCross

  I'm working on an institution that has a really strong sense of "possession" - each line of software we write should be only ours. Ironically, I'm the only programmer (ATM), but we're planning in hiring others. Since my bosses wouldn't count the new programmers as people they can trust, they have an issue with the copies of the source code. We use Git, so they would have a entire copy of each of the projects they work on, when they clone the repository. We can restrict access to them to a single key with Gitolite and bind that to their PC's, but they can copy those keys to another computer and they would have the repository access in another PC. Also (and the most obvious method) they could just upload the files somewhere else, add another remote, or just copy the files to an USB drive. Is there any (perhaps clever) way to prevent events like these?

• How do I implement Unreal-like object serialization?

  - by MrWiggels

  Recently, I've been working on the core of my engine, and as I'm moving forward I find myself developing throwaway code to read files and simple data into the engine. This got me thinking about how I should implement a file management system. After a bit of googleing I came across the Unreal Package format, and boy does it look like the perfect one. I think it's good because the way how it allows you to separate different assets into different packages and allow something like a level to reference the different packages. I was just wondering, is this possible with C#? Because the built-in serialization API in .NET does not seem to support any form of this, only reading and writing to a single file.
