• install and update issue

  - by Newben

  I get some error messages as soon as I try to install or update packages : ...

They have been ignored, or old ones used instead. ... I tried to find something by googling but I didn't find any satisfactory response. Anybody has an idea ?

• iOS NSError with global handler

  - by Sebastian Dressler

  I am in the beginning of programming an iOS app. Having read the Apple guides on how to deal with errors, I got the following most important points: Exceptions are for programmers Use NSError for the user Now, NSError is usually passed as out-argument which can then be used inside and has to be checked by the caller. However, I'm asking myself whether it is a good idea to use a global error handler, say a singleton which wraps around NSError and could be used to trigger errors and error handling from within the called function. Is there anything against that method or would it be a bad practice?

• Need a CDN with SSL

  - by Till

  We currently use Edgecast through Speedyrails. Back when I did my research they were both fast and very cost-effective. I haven't looked in a while, but now we need SSL on our assets as well. I reached out to our current provider and they want a setup fee and something like 260 USD per host per month (we use multiple hosts currently). I looked at AWS Cloudfront and it seems the most cost affective way to get SSL, but it's not a custom domain then (e.g. cdn.example.org), which I could live with. Has any else researched this lately and has any providers to get in touch with - can be resellers or direct buys. I'm not looking for a bargain, I just want to get an idea what these things cost. Edit, 2012-08-23: Must have is custom origin. E.g. I don't want to manually upload files somewhere else. Edgecast and Cloudfront both support this.

• Server costs and back loading for mobile devices

  - by user23844

  A company approached me to design an MMO for the mobile platform and I have the perfect idea for them. My question is how much would a server for a FTP game that has both a PVE element and PVP cost? Also do you think that it would be better or is it even possible to back load the data onto the phones (trying to come up with some interesting way to back up the data in case of emergency). I don't want the game to be totally online reliant (I want to appeal to not only phone users but also iPod touch users) and for there to be an offline mode. If you can't tell this is my first game besides simple projects I've done on the side. Any help would be greatly appreciated.

• Program/Wrapper (how do you call it) to automate a certain script

  - by user10324

  In this question a script is provided, that minimizes all the other windows except the active one. But the thing is, to trigger this script a (shortcut) key-combination has to be pressed. I would love it, if it would be possible to automate this behavior, i.e. no matter what I do, only the active window is not minimized. This way I cannot view more then one open window at the same tine, which is what I'm after. Is it possible to write a script, that does this ? I a question I asked a while ago (where I learned about the above script), someone said, the proper way to do this, would be through a wrapper through which every program starts. I would also be very happy with a more sloppy solution, like activating this script 100 times per second (simulating pressing the shortcut combination a 100 times per second), if it is feasible - although I was warned, that that may not be a very good idea.

• Why is it good to split a program into multiple classes?

  - by user1276078

  I'm still a student in high school (entering 10th grade), and I have yet to take an actual computer course in school. Everything I've done so far is through books. Those books have taught me concepts such as inheritance, but how does splitting a program into multiple classes help? The books never told me. I'm asking this mainly because of a recent project. It's an arcade video game, sort of like a flash game as some people have said (although I have no idea what a flash game is). The thing is, it's only one class. It works perfectly fine (a little occasional lag however) with just one class. So, I'm just asking how splitting it into multiple classes would help it. This project was in JAVA and I am the only person working on it, for the record.

• How do I find the dependencies for a program before trying to compile it?

  - by Ubuntu_beginner

  I was trying to cross-compile a program for ARM. While compiling I was very much irritated as I had to look for a number of dependencies e.g fatal error: abc/xyz.h: No such file or directory compilation terminated. After ensuring that compiler gets the missing files, when I recompiled, I got same error for about 30 files. I have no idea if that is normal behaviour. If it is normal, is there a method which can help the compiler find the dependencies on its own? If that is not normal, then please explain what I'm doing wrong.

• Can't read CDs, can't create USB... how do I install Ubuntu?

  - by user68080

  Hello everyone and thank you in advance for your time. I have troubles with the latest Ubuntu distribution: since I upgraded to 12.04 Ubuntu has started having troubles (internal errors, packages that crash repeatedly, I can't install new packages, Ubuntu Software Center crashes, Java apps that worked stopped working and display weird mistakes, files were corrupted... a mess). I ultimately decided to format everything and install 12.04 from scratch. I made a backup and everything, but now I have troubles installing ubuntu 12.04. Specifically, a CD I burned with Brasero that works on another PC is not read by my laptop (not at boot phase, nor inside Ubuntu), and when I try to create a USB with Ubuntu (following the instructions I found on the ubuntu site) Startup Disk Creator stops at 22% saying that "the codes do not match". Any idea on what to do next? No, I can't buy a new PC.

• GUI app for Bandwidth Shaping (Internet Speed Limiter)

  - by Luis Alvarado

  This is a similar question as this one: Limit internet bandwidth but in this case I am looking for a GUI app. The other question was 2+ years ago so a GUI might be available that I could use to not only monitor but also change the maximum speed at which clients can download. A WebApp or a GUI app will help. It needs to work on 12.04 or newer. Just to give an idea, I am looking for something similar to NetLimiter that gives me the control to know: How much Download/Upload speed an IP/Mac has (Assuming this is a LAN) Limit the Download/Upload speed for an IP/Mac. Option to say I what time a speed can be limited or not. Can cap when a certain amount has been downloaded/uploaded (Like 250MB per day)

• What is the point in using real time?

  - by bobobobo

  I understand that using real time frame elapses (which should vary between 16-17ms on average) are provided by a lot of frameworks. GetTimeElapsedSinceLastFrame, and it gives you the wall clock time. But should we use this information in basic physics simulation? It looks to me to be a bad idea. Say there is a slight lag on the machine, for whatever reason (say a virus scanner starts up). The calculations all jump, and there is no need for this. Why not use a virtual second and ignore wall clock time? For gameplay on the level of Commander Keen, shouldn't you always use the virtual second and not real-time? (Besides stopwatch timing for race games) I don't see a need to use real time and not a fixed 16ms time step.

• Why Android for new (micro) consoles?

  - by Klaim

  There are a lot of new (micro) consoles with Android inside coming soon or already there (OUYA for example). My question is: why use Android and not another OS as base for these consoles? I assume that there are pragmatic answers to this but I can't see any clear killer feature. For example, one can assume that any stable Linux distribution would work (like Valve seem to think). Android is primarily targetted at mobile platforms which mean it is built around the idea of being interrupted which goes against a lot of what console devs needs in new hardware - but is not killing Android as a platform for gamedev either as it's just a constraint. Why not another OS? What's the Android killer features that make micro-console builder using it instead of Linux or anything else?

• Pygame - CollideRect - But How Do They Collide?

  - by Chakotay

  I'm having some trouble figuring out how I can handle collisions that are specifically colliding on the top or bottom a rect. How can specify those collisions? Here's a little code snippet to give you an idea of my approach. As it is now it doesn't matter where it collides. # the ball has hit one of the paddles. send it back in another direction. if paddleRect.colliderect(ballRect) or paddle2Rect.colliderect(ballRect): ballHitPaddle.play() if directionOfBall == 'upleft': directionOfBall = 'upright' elif directionOfBall == 'upright': directionOfBall = 'upleft' elif directionOfBall == 'downleft': directionOfBall = 'downright' elif directionOfBall == 'downright': directionOfBall = 'downleft' Thanks in advance. **EDIT** Paddle rect: top ____ | | | | | | Sides | | ---- bottom I need to know if the ball has hit either the top or the bottom.

• Can't install Ubuntu 13.04

  - by Beaker1210

  I am trying to install Ubuntu 13.04 on a Dell Mini 10 that is currently running Qimo. I want to replace the old operating system entirely. When I turn on the computer and boot from the USB stick it brings up a black screen that says: Boot: I have no idea where to go from here. I created the bootable USB stick using Universal USB installer. I've used the same process for installing Ubuntu on other machines in the past have never had this issue. Thanks in advance for the help. :)

• VB6 general search form

  - by SilentRage47

  I'm working on an old vb6/access2003 app which is used to handle orders, bills of materials and that sort of things. I'm thinking about creating a form that I call every time the users needs to search for something. This should work like these: Click on the field to complete, let's say name of a buyer Open new form, search for the client and click on it Return the name of the buyer to the previous form (probably the header of the order) So, I would need to pass to the new form something that identify the type of search I have to do (so what access table to open) and return some values. Is my idea correct or there something better? I would like to use only one form for all the searches, now the app works with a lot of msflexgrid for every form.

• Advice on triple/quadruple-booting?

  - by professorfish

  I am currently running Windows 7 Home Premium x64 on my laptop. I would like to install more than one Linux distro, IN ADDITION TO Windows 7. How do I go about this, what do I need to be careful and aware of, is it possible? The specific distros I might eventually install: Definitely: Ubuntu (is it a good idea to install the Linux-Secure-Remix version?) Almost definitely: OpenSUSE Probably: Zorin Possibly: Arch Possibly: Fedora Possibly: FreeBSD Computer details: Successfully used WUBI for Ubuntu in the past Recently reinstalled Windows using the RECOVERY partition Windows 7 Home Premium x64 model: ASUS K53U series AMD Brazos Dual Core E450 1.65 GHz 750GB hard drive, currently partitioned into C: (300GB total, 246 GB free), D: (373GB - total, 167 GB free), and RECOVERY (the rest of the space, I think) 4GB RAM Can I be sure that GRUB will work, if WUBI has worked? In short, how do I go about triple- or quadruple-booting Windows 7, Ubuntu and other distros? What do I need to be aware of? How do I set up the partition structure? Thank you in advance

• Best way to create neon glow line effect in AS3?

  - by Phil

  What's the best way to create a neon glow line effect in Flash AS3? Say similar to what's going on in the game gravitron360 on the xbox 360? Would it be a good idea to create movieclips with plain lines drawn in them and then apply a glow filter to them? or perhaps just apply the glow filter to the entire movieclip layer the movieclips are on? or just draw them manually and create a glow effect by converting the lines to fills and then softening edges? (wouldn't blend as well but would be the fastest CPU wise?) Thanks for any help

• How do I get started with fog type effects in a first person game?

  - by Dream Lane

  Hey guys, I'm currently using JME3 to learn 3d game development in java, and I have run into a situation. I would like to add fog effects to my games, but I don't even know where to start to implement this. I know how to set the camera's far frustum to limit the render distance, but that just simply makes a sharp cutoff. I'd like the fog it up a bit to make it feel more natural. I'm looking for an answer that points me into the correct direction. I'm not looking for specific code snippets or even JME3's engine specifics. I just want to get an idea of how this stuff works in general. Thanks!

• How to have a PHP web site that can play videos offline?

  - by greco

  Our client asked to implement a system with web technologies and the basic functionalities of: We have 3 users: Admin, User, Visitor. provide videos with an indexing system. Videos and other info about them are uploaded from an admin panel. Users can make playlists, add extra info to videos etc. Visitors watch playlists, videos, track their progress etc. This are some of the very basic functionalities of the system, just to get an idea. So we agreed it's a saas project and we started with php,symphony,jquery,requireJS etc. Now our client says that he wants the user and visitor part has to be accessible offline only. He says the user can download the videos and software, and continue offline. What are your suggestions on this? Provide the ability for the user to download a local server, or another way?

• Need some advice on CLI design, I need to provide simple but powerful command line options

  - by howtechstuffworks

  I am writing a utility that runs on RHEL5 command line. I need my command line options to be simple but powerful. I looked at the various UNIX utilities to get an idea of how simple command line utilities have to be. Do you guys suggest any documents/links that talk about command line etiquette? I am modelling my utility on top of LVM (that's all the info I can give for now). I know it's a software engineering question, but I thought it would be appropriate to post here. Please advise.... PS: I am not asking for details about getopt or command line utility parsers.....

• How can I programmatically block user input for a given time?

  - by black_puppydog

  As a person working in computer science working offline to avoid facebook and thelike is not always (meaning hardly ever) possible for me since I mostly have to be online to work. I have tried leechblock and similar things but the problem becomes that at some point I start making systems for myself to hack, which is kind of pointless if oyu have root. I would very much like to try out the method described here. (Short version: reboot your PC every time finish a task or get bored with it) Unlike for the author of this blog my work is mainly done not in screen sessions but in IDEs ans other not-so-fast-to-start-up stuff, meaning a full reboot including loading all my programs will take its time. So, the question is: How can I block all user input and preferrably blank the screen for a given amount of time? The idea would then be to have a keyboard shortcut to activate the script/program (which would probably also have to have root i guess?)

• Geographic location settings

  - by JochemTheSchoolKid

  I am building an website. It has an .nl domain. Now only my domain is showing up on google.nl I hope I can change this somehow that it could be findable in all google's (like google.com / co.uk) and so on. If I look on google forums. They say go to webmaster tools and change your geographic position over there. But I have added this site and I am not able to change it there because there is no select box. I dont have any idea were to search (yes I searched on google offcourse) or where to ask for this special problem. So maybe here can someone redirect me or explain me what is possible and what not. The question is can I make an .nl domain findable in (almost) all google search sites? And so on how can I do that. Picture of my google webmaster tools (nl): http://i.stack.imgur.com/ZuP4L.png

• Is Carnegie Mellon (CMU) a Javaschool? Are any prominent universities in the US javaschools? [on hold]

  - by user106149

  I'm guessing CMU would teach C and other unmanaged languages (their course listing shows Principles of Functional Programming as a required course for a BSCS), but it's hard to tell from course listings. I'm looking into applying there, where I have an OK chance of getting in , as well as some other mid-to high tier CS schools. I'm wondering how you can tell if a school mainly teaches Java or goes into C/C++. Everyone says (and I agree, from my current programming knowledge) that learning Java in college exclusively is a bad idea, so I'm hoping to avoid ending up at a 'Javaschool.'

• Programming C++ using Qt4

  - by DaGhostman Dimitrov

  Hey guys I am really new to the C++ programing I have a little knowledge in C and a bit more in C++, but I do not know them enough to call myself a programmer. I am working as a PHP Web Developer I like being a crafts man and creating things so that is the reason to combine the programming with web development. I think that I could really benefit from both of them and so... My question is: Is it a good Idea to learn C++ with Qt or not? Can you give me pros and cons of both? Note: I do not want to become a programmer and give up the web development I want to combine them both.

• XNA VertexBuffer.SetData performance suggestions

  - by CodeSpeaker

  I have a 3d world in a grid layout where each grid cell contains its separate vertex and index buffer for the mesh/terrain of that cell. When the player moves outside the boundaries of his cell, i dynamically load more cells in his walking direction based on his viewing distance. This triggers x number of vertex and indexbuffer initializations depending on how many cells that needs to be generated and causes the framerate to drop annoyingly during this time. The generation of terrain data is handled in a separate thread and runs smoothly. The vertex and index buffers are added during the update cycle of the game loop. I´ve tried batching the number of cells to be processed to avoid sending too much data at once into the buffers, which worked ok at a shorter viewing distance (about 9 cells to process), but not as well at greater distances with around 30 cells to process. Any idea how i can optimize this?
