• How Visual Studio could help to avoid duplicating code?

  - by MegaMind

  I work within a team of developers. Everyone is making their changes without carrying too much if the same thing is already implemented in the codebase. This leads to classes constantly growing and to severe duplication. I want to add line items to class definitions from which a developer could judge what this class has. Would it help? How to do it in Visual Studio? If it wouldn't help, what would be the better alternative to encourage the developers to check if something exists before implementing it?

• Problem: Black screen after resume

  - by Robert

  Problem: Black screen after resume I found the below statement that I provided the link for but, no instructions with it for a person that's new to Ubuntu on what exactly to do to fix the problem. Can someone clarify this for me? Thank you. Ubunu 13.10 AMD A6-3420M APU with Radeon(tm) HD Graphics × 4 64bit Toshiba L775 My computer boots to a black screen, what options do I have to fix it? Typical scenario is "use a laptop docked with lid closed, only the external screen is active, suspend, take the laptop, open it somewhere"... which leads to "no screen active". To debug this problem, check if gnome-settings-daemons is getting a signal that the display configuration has changed, by running xtrace against it, and look for a RRScreenChangeNotify event when resuming the machine. If that signal is being sent, then it indicates a possible bug in g-s-d. Otherwise, it suggests a bug in either X or (more likely) the kernel which is not causing the signal to be emitted to begin with.

• How can a script detect if the user is idle

  - by josinalvo

  I want to check, inside a bash script (*), how much time the user of a X session has been idle The user himself does not have to be using bash, but just X. If the user just moved the mouse, for example, a good answer would be "idle for 0 seconds". If he has not touched the computer in 5 minutes, a good answer would be "idle for 300 seconds" The reason to not use xautolock straight away is to be able to implement some complex behavior. For example, if the user is idle for 10 minutes, try to suspend, if he is idle for more 5 minutes, shutoff (I know it sounds odd, but suspend does not always work here ...) (*)or could be another language.

• Take Camera Phone Macro Photos with a Cheap Laser Pointer Lens

  - by Jason Fitzpatrick

  Inside those cheap laser pointers you see in the grocery store checkout line there’s a handy little plastic lens that, when slapped on your phone’s camera, makes it easy to take macro photographs. In this tutorial, they take the lens from a laser point and secure it using tape and a bobby pin. An alternative method to achieve the same end (and with a higher quality lens) is to dismantle a CD/DVD drive to source the lens and use painter’s tape to hold the lens in place–this is the technique I used several years ago, check out the tutorial video here.

• Is an 'if password == XXXXXXX' enough for minimum security?

  - by Prof Plum

  If I create a login for an app that has middle to low security risk (in other words, its not a banking app or anything), is it acceptable for me to verify a password entered by the user by just saying something like: if(enteredPassword == verifiedPassword) SendToRestrictedArea(); else DisplayPasswordUnknownMessage(); It seems to easy to be effective, but I certainly would not mind if that was all that was required. Is a simple check on username/password combo enough? Update: The particular project happens to be a web service, the verification is entirely server side, and it is not open-source. Does the domain change how you would deal with this?

• Could JQuery and similar tools be built into the browser install?

  - by Ozz

  After reading another question about JQuery and CDN's, is it feasible for tools like JQuery to "come with" the browser, thus reducing/eliminating the need for the first download from a CDN, or from your own host server. JQuery files specifically are pretty small, so you could easily have a number (all?) of the different versions as part of a browser install. Now fair enough, this would increase install footprint, download time for the browser itself. Then sites could check "local" first, before CDN (which then caches), before finally defaulting to downloading from the website server itself. If this is feasible, has it been done, and if not, why hasn't it be done?

• Synchronise graphics and logic code

  - by Skeith

  I have a procedural approach to the game loop that runs various classes. it looks like this: continue any in progress animations check for used input apply AI move things resolve events such as collisions draw it all to screen I have seen a lot of posts about how drawing should be running separately as fast as it can, possibly in another thread. My problem is that if the drawing runs as fast as it, can what happens if it tried to draw while I'm still applying the AI or resolving a collision? It could draw the wrong thing on screen. This seems to be a well established idea so there must be an explanation to this problem as I just cant get my head around it. The only solution I have is to update the screen so fast that any errors like that get refreshed before we see them but that sounds hacky. So how does this work / how would you implement it so that they are in sync but running at different speeds?

• It is worth planning before jumping in the code?

  - by Rushino

  I always thought that planning is important for a game. But i don't know at which point. Some are telling me to code instead of planning but i feel like its still important because when you will be in the code you will know what to do next more easily. I am currently working on a game that will have lots of content so i decided to start a design document introducing thoses content and at a side-level i am doing proofs of concept to check if it can be done. Parts of each proofs of concept then could be used later in the real game. EDIT: I am working alone on this project. So my question is : It is worth planning before jumping in the code ? Im still interested to know what others have to say about this. Cause i still get some poeple saying i should code instead of thinking.. so what your opinion on this ?

• How to determine which cells in a grid intersect with a given triangle?

  - by Ray Dey

  I'm currently writing a 2D AI simulation, but I'm not completely certain how to check whether the position of an agent is within the field of view of another. Currently, my world partitioning is simple cell-space partitioning (a grid). I want to use a triangle to represent the field of view, but how can I calculate the cells that intersect with the triangle? Similar to this picture: The red areas are the cells I want to calculate, by checking whether the triangle intersects those cells. Thanks in advance. EDIT: Just to add to the confusion (or perhaps even make it easier). Each cell has a min and max vector where the min is the bottom left corner and the max is the top right corner.

• Installing along side of Windows 8

  - by Jake

  It appears as though many people are having problems installing Ubuntu along side Windows 8. My problem, however, seems to be sufficiently different to be unique among such problems. I can't get the Ubuntu 12.10 live-USB installer to run. When I boot I get the following four options: Run from this USB Install to disk Check memory (I can't remember the last one) I have tried the top two. Both result in the screen going black briefly then windows 8 booting as per usual. Does anyone know how I may manage to overcome this problem?

• What is the term for a really BIG source code commit?

  - by Ida

  Sometimes when we check the commit history of a software, we may see that there are a few commits that are really BIG - they may change 10 or 20 files with hundreds of changed source code lines (delta). I remember that there is a commonly used term for such BIG commit but I can't recall exactly what that term is. Can anyone help me? What is the term that programmers usually use to refer to such BIG and giant commit? BTW, is committing a lot of changes all together a good practice? UPDATE: thank you guys for the inspiring discussion! But I think "code bomb" is the term that I'm looking for.

• How to detect GLSL warnings?

  - by msell

  After compiling a shader with glCompileShader, I can call glGetShaderiv with GL_COMPILE_STATUS to check if the shader compiled successfully. I can also call glGetShaderInfoLog to get information about possible errors, warnings or other info. The information log returned by this function is unspecified. In a tool where users can write their own shaders, I would like to print all errors and warnings from the compilation, but nothing if no warnings or errors were found. The problem is that the GL_COMPILE_STATUS returns only false if the compilation failed and true otherwise. If no problems were found, some drivers return empty info log from glGetShaderInfoLog, but some drivers can return something else such as "No errors.", which I do not want to print to the user. How is this problem generally solved?

• Best choice for 3D Physics Engine for C#/XNA

  - by Nic Foster

  Since 2007 I've been working on the development of an open-source game engine, and have been using JigLibX for 3D Physics. However, the developers on the project have stopped contributing to it for over 2 years now, and it's lacking features I need, or have major bugs in certain features. What are some good choices for 3D physics engines that are written purely in C#? Are there any that are more complete than JigLibX? EDIT: I just stumbled upon an engine called BEPUphysics. It was supported up until May 2012, which is fairly recent. I may check it out, any information that you guys could give on how complete the engine is would be great.

• How can I make a case for "dependency management"?

  - by C. Ross

  I'm currently trying to make a case for adopting dependency management for builds (ala Maven, Ivy, NuGet) and creating an internal repository for shared modules, of which we have over a dozen enterprise wide. What are the primary selling points of this build technique? The ones I have so far: Eases the process of distributing and importing shared modules, especially version upgrades. Requires the dependencies of shared modules to be precisely documented. Removes shared modules from source control, speeding and simplifying checkouts/check ins (when you have applications with 20+ libraries this is a real factor). Allows more control or awareness of what third party libs are used in your organization. Are there any selling points that I'm missing? Are there any studies or articles giving improvement metrics?

• How to go about "taking over" an open-source project?

  - by LuxuryMode

  There's an open-source project that I'm interested in and use regularly. It's licensed under the Apache License 2.0 and it has basically no activity any more. It's hosted on Google Code and I'm interested in continuing it's development. I'm new to the open-source process and I'm trying to figure out the appropriate way to go about this. Can I just check it out and push it to github so I can continue it's development in the open there? Should I contact the project "owner" first? Also, do I leave all the author information at the top of the classes, etc even though I'm going to be making changes..(I'm assuming the answer is yes)? Also, how do I practically adhere to the license requirement of "all modifications are clearly marked as being the work of the modifier"? Do I place a comment by every change I make?

• could not save the file /usr/... permission denied (13.04)

  - by plaguedoctor

  I am running Ubuntu 13.04 and am trying to create an .sh file for conky in /usr/bin using gedit. When trying to save I get the error dialogue: Could not save the file /usr/bin/conky-start.sh You do not have the permissions necessary to save the file. Please check that you typed the location correctly and try again." From searching, I think I have to run a command in terminal to allow permission, but I couldn't find out what that is. Edit: I'm trying to create the file conky-start.sh, not change or run it. Thus far, I've opened gedit, copied and pasted some required info from the net, and I'm trying to save-as /usr/bin/conky-start.sh Perhaps I need to create the file first in terminal, then edit it? How would I do that?

• svn-based versioning tool, problem with network timeout

  - by Scarlet

  My dev team was committed a versioning tool based on Subversion to run on Windows (our svn client is sliksvn). We're developing with Delphi XE2, should that matter. We're asked to implement a "check for updates availability" feature, which has to work as follows: Connect to the SVN repo via svn+ssh protocol; See if there are changes to receive and list them; Let the user decide if he wants to receive changes or not. We don't have a great knowledge on svn, so we thought to implement that thing client side by a certain number of CreateProcess calls that wrap directly proper svn commands. Anyways what we perceived is that if network problems should arise, such like a connection drop, svn client hangs forever waiting for the operation to close instead of failing for timeout. We know that CreateProcess can be given a timeout argument, but it wouldn't be correct to use it, as we can't know from outside how long will be the svn operation taking to complete. Is there any way to avoid that deadlock?
