• kile does not get keyboard input, respond to Alt+F

  - by vishvAs vAsuki

  I use 11.10 with Unity. I use two kde apps a lot - kile and kate. Since the latest upgrade, I have observed two problems: a] I can never use Alt+F to select the file menu (works with other apps), yet when I press Alt, kile's menu comes up in the status bar. b] A few times every day, while using kile (haven't used kate as much recently), the keyboard stops responding (just in the 'editor' portion, rather than in structure-tree navigation). I cannot enter any text, but mouse works fine. I usually restart kile to continue working. One inconsistent way to reproduce it (multiple times today): I cut text from one open document using Ctrl-X switched to another document in the same kile window using Ctrl-Tab, then this happened. c] Sometimes, in kate, I can type in the editor but the keyboard won't work in the 'File open dialog'. How do I fix the above?

• Better Programming By Programming Better?

  - by ahmed

  I am not convinced by the idea that developers are either born with it or they are not. Where’s the empirical evidence to support these types of claims? Can a programmer move from say the 50th to 90th percentile? However, most developers are not in the 99th or even 90th percentile (by definition), and thus still have room for improvement in programming ability, along with the important skills.The belief in innate talent is “lacking in hard evidence to substantiate it” as well.So how do I reconcile these seemingly contradictory statements? I think the lesson for software developers who wish to keep on top of their game and become experts is to keep exercising the mind via effortful studying. I read a lot technical books, but many of them aren’t making me better as a developer.

• Tester-Developer communication

  - by HH_

  While a lot is written about developer-developer, developer-client, developer-team manager communications, I couldn't find any text which gives guidelines about tester-developer communication and relation. Whether testers and developers are separate teams or in the same one (in my case, I am a lone tester in an agile development project), I have the belief that how testers are perceived is extremely important in order for testing to be well-accepted, and to serve its goal in enhancing the quality of the project (for example, they should not be viewed as a police force). Any advices, or studies about how a tester should communicate with developers? Thank you

• How to report a crash bug with nothing on screen

  - by winniemiel05

  I would like to report an installation bug, but I can't launch ubuntu-bug : On my tablet (LDLC Janus, an Intel based tablet without OS installed by default), I have a problem when I install Ubuntu 11.04 or 11.10. Once the installation is finished, when I reboot, there is ABSOLUTELY nothing on screen, but Ubuntu boot correctly anyway : I choosed auto-login mode and I can hear the login sound. Even if I Ctrl+Alt+F1 or F2... there is nothing. But the livecd works fine (even touch screen even if without multi touch). I tried to install 10.10 it works, but as soon as I upgrade the same problem occure. i installed Fedora 15 and then Fedora 16 (because of other problems) and no problems with them. I would like to report this bug on launchpad but I don't know how to do to give devs logs files and other useful files which could help debug. Thanks a lot for your answer, I would really prefer using my tablet with Ubuntu (I miss U1, USC, Unity)

• How do people get around the Carmack's Reverse patent?

  - by Rei Miyasaka

  Apparently, Creative has a patent on Carmack's Reverse, and they successfully forced Id to modify their techniques for the source drop, as well as to include EAX in Doom 3. But Carmack's Reverse is discussed quite often and apparently it's a good choice for deferred shading, so it's presumably used in a lot of other high-budget productions too. Even though it's unlikely that Creative would go after smaller companies, I'm wondering how the bigger studios get around this problem. Do they just cross their fingers and hope Creative doesn't troll them, or do they just not use Carmack's Reverse at all?

• Is there any difference between storing textures and baked lighting for environment meshes?

  - by Ben Hymers

  I assume that when texturing environments, one or several textures will be used, and the UVs of the environment geometry will likely overlap on these textures, so that e.g. a tiling brick texture can be used by many parts of the environment, rather than UV unwrapping the entire thing, and having several areas of the texture be identical. If my assumption is wrong, please let me know! Now, when thinking about baking lighting, clearly this can't be done the same way - lighting in general will be unique to every face so the environment must be UV unwrapped without overlap, and lighting must be baked onto unique areas of one or several textures, to give each surface its own texture space to store its lighting. My questions are: Have I got this wrong? If so, how? Isn't baking lighting going to use a lot of texture space? Will the geometry need two UV sets, one used for the colour/normal texture and one for the lighting texture? Anything else you'd like to add? :)

• How to name an subclass that add a minor, detailed thing?

  - by Louis Rhys

  What is the most concise (yet descriptive) way of naming a subclass that only add a specific minor thing to the parent? I encountered this case a lot in WPF, where sometime I have to add a small functionality to an out-of-the-box control for specific cases. Example: TreeView doesn't change the SelectedItem on right-click, but I have to make one that does in my application. Some possible names are TreeViewThatChangesSelectedItemOnRightClick (way too wordy and maybe difficult to read because there is so many words concantenated together) TreeView_SelectedItemChangesOnRightClick (slightly more readable, but still too wordy and the underscore also breaks the normal convention for class names) TreeViewThatChangesSIOnRC (non-obvious acronym), ExtendedTreeView (more concise, but doesn't describe what it is doing. Besides, I already found a class called this in the library, that I don't want to use/modify in my application). LouisTreeView, MyTreeView, etc. (doesn't describe what it is doing). It seems that I can't find a name which sounds right. What do you do in situation like this?

• Are there examples of non CRUD approaches?

  - by Pieter B

  I'm a programmer but also have worked as an archivist. As archivist it's a lot about keeping data. I often get into arguments with colleagues when it comes to operations on data. I don't like the U and the D in CRUD too much. Rather then update a record I prefer to add a new one and have a reference to the old record. That way you build a history of changes. I also don't like deleting records but rather mark them as inactive. Is there a term for this? Basically only creating and reading data? Are there examples of this approach?

• What's wrong with JavaScript

  - by ts01

  There is a lot of buzz around Dart recently, often questioning Google motivations and utility of Dart as replacement for JavaScript. I was searching for rationale of creating Dart rather than investing more effort in ECMAScript. In well known leaked mail its author is saying that Javascript has historical baggage that cannot be solved without a clean break. But there is only one concrete example given (apart of performance concerns) of "fundamental language problems", which is an existence of a single Number primitive So, my questions are: How an existence of a single Number primitive can be a "fundamental problem"? Are there other known "fundamental problems" in JavaScript?

• How to zoom in&zoom out

  - by stanimir

  While using 10.04 and the previous versions I used to put ctrl+F6 to zoom in and subsequently ctrl+F7 to zoom out. Now I can't even find the options to zoom in and zoom out in the "keyboard shortcuts". I tried "the Magnifier" in the Compiz but really can't understand what is going on right there. There is simple question I would like to ask: What to do so as to be able to zoom in with ctrl+F6 and zoom out with ctrl+F7? Thanks a lot.

• DNS slowdowns on development environment

  - by Sequenzia

  I have a local development environment setup on my Mac. I am running an Ubuntu Web Server inside of a Virtual Box VM. I setup a host file on my Mac that points my dev site to the IP of the Ubuntu Virtual Server. Everything works good other than the fact a lot (not all) of the time it takes more than 5 seconds to load a page. I used firebug to track down where the problem is and when it's slow the DNS part of my request is taking over 5 seconds. Like I said it's not all the time. Sometimes it resolves and loads the page within milliseconds. The same page one click will be super fast and then the next time it takes over 5 seconds. It's really slowing me down and I am not sure what is causing it. Anyone have any ideas? Any help would be great. Thank

• Factors to consider when building an algorithm for gun recoil

  - by Nate Bross

  What would be a good algorithm for calculating the recoil of a shooting guns cross-hairs? What I've got now, is something like this: Define min/max recoil based on weapon size Generate random number of "delta" movement Apply random value to X, Y, or both of cross-hairs (only "up" on the Y axis) Multiply new delta based on time from the previous shot (more recoil for full-auto) What I'm worried about is that this feels rather predicable, what other factors should one take into account when building recoil? While I'd like it to be somewhat predictable, I'd also like to keep players on their toes. I'm thinking about increasing the min/max recoil values by a large amount (relatively) and adding a weighting, so large recoils will be more rare -- it seems like a lot of effort to go into something I felt would be simple. Maybe this is just something that needs to be fine-tuned with additional playtesting, and more playtesters? I think that it's important to note, that the recoil will be a large part of the game, and is a key factor in the game being fun/challenging or not.

• Python or C server hosting for indie development

  - by Richard Fabian

  I've written a lot of the game, but it's singleplayer. Now we want to join up and play together. I want to host it like an MMO, but haven't got any personal ability to host (no static IPs or direct access to a reasonable router that will allow me to port forward) so I wondered if there were any free / very cheap hosting solutions for people developing games that need to develop their MMO side. In my case it's a world server for a 2D game where the world map can be changed by the players. So, GAE sounds expensive, as there would be quite a few updates per second (I heard they bill for data updates but not for download, but can't find refernce to billing anywhere on the FAQs) I'd prefer to be able to write the server in python as that's what the game is written in (with pygame), but C is fine, and maybe even better as it might prompt me to write some more performant world generator code ;)

• Tool to convert from XML to CSV and back to XML without losing information?

  - by Lanaru

  I would like to convert an XML file into CSV, and then be able to convert that CSV back into the original XML file. Is there a tool out there that makes this possible? The reason I want to do this is that I want to generate a ton of data to be stored in an xml file that my program will parse. I can easily generate a lot of data with a CSV file through the use of Excel macros, so that's why I'm looking for a tool to convert between these two formats. Any alternative suggestions are greatly appreciated.

• Why is email HTML stuck in the 90's?

  - by Sean Dunwoody

  (disclaimer - I've already tried asking this on StackOverflow, but apparently it was off topic. If the same is true here please let me know and I'll close/delete this question.) I've spent about a day putting together a frustrating email newsletter, using tables, inline styles etc. It feels a lot harder than it should be. I was just wondering, is there any reason why email clients have such poor support of HTML and CSS (CSS in particular)? I would have imagined they'd be scrambling to outdo each other in this department ... Is is a security thing (I can't really imagine why)? Or are they just lazy?

• Does the use of debuggers have an effect on the efficiency of programmers? [closed]

  - by alain.janinm

  Possible Duplicate: Are debugging skills important to become a good programmer? I'm a young Java developer and I make a systematic use of the Netbeans debugger. In fact, I often develop my applications when I debug step by step in order to see immediately if my code works. I feel spending a lot of time programming this way because the use of debugger increase execution time and I often wait for my app to jump from a breakpoint to an other (so much that I've the time to ask this question). I never learned to use a debugger at school, but at work I've been told immediately to use this functionality. I started teaching myself to use it two years ago, and I've never been told any key tips about it. I'd like to know if there are some rules to follow in order to use the debugger efficiently. I'm also wondering if using the debugger is eventually a good practice? Or is it a loss of time and I've to stop now this bad habit?

• Being prepared for a code review as a developer?

  - by Karthik Sreenivasan

  I am looking for some ideas here. I read the article How should code reviews be Carried Out and Code Reviews, what are the advantages? which were very informative but I still need more clarity on the question below. My Question is, Being the target developer, can you suggest some best practices a developer can incorporate before his code is going get reviewed. Currently I practice the following methods PPT for a logical flow Detailed comments. Issue: Even though I have implemented the above practices, they do not help on the review. The problem I faced is, when certain logic is referred, I keep searching for the implementation and the flow and too much time is wasted in the process and I get on people’s nerve. I think a lot of developers would be going through what I am going through as well.

• mp3 file streaming/download - apache server memory issue

  - by Manolis

  I have a website, in which users can upload mp3 files (uploadify), stream them using an html5 player (jplayer) and download them using a php script (www.zubrag.com/scripts/). When a user uploads a song, the path to the audio file is saved in the database and i'm using that data in order to play and show a download link for the song. The problem that i'm experiencing is that, according to my host, this method is using a lot of memory on the server, which is dedicated. Link to script: http://pastebin.com/Vus8SRa7 How should I handle the script properly? And what would be the best way to track down the problem? Any ideas on cleaning up the code? Any help much appreciated.

• Advice On Price Comparison Affiliate Programs

  - by pixelcook

  I want a price comparison feature on my site similar to Consumer Reports' "Price & Shop" section. They use PriceGrabber.com, but as far as I can tell they have a special deal with CR, so I can't get a similar service for my site. I've gathered that I need to use an affiliate network, but the whole thing seems so shady, I don't really know what sites are legit, and I don't know what sites offer the price comparison feature. Datafeedfile.com comes up a lot during my searches, but the ugly site makes me wary. Does anyone have any experience with this? What affiliate networks do you recommend? Or should I be looking at something else altogether?

• Methods to Manage/Document "one-off" Reports

  - by Jason Holland

  I'm a programmer that also does database stuff and I get a lot of so-called one-time report requests and recurring report requests. I work at a company that has a SQL Server database that we integrate third-party data with and we also have some third-party vendors that we have to use their proprietary reporting system to extract data in flat file format from that we don't integrate into SQL Server for security reasons. To generate many of these reports I have to query data from various systems, write small scripts to combine data from the separate systems, cry, pull my hair, curse the last guy's name that made the report before me, etc. My question is, what are some good methods for documenting the steps taken to generate these reports so the next poor soul that has to do them won't curse my name? As of now I just have a folder with subfolders per project with the selects and scripts that generated the last report but that seems like a "poor man's" solution. :)

• Collision Detection in Java for a game

  - by gordsmash

  Im making a game in Java with a few other people but we are stuck on one part of it, making the collision detection. The game is an RPG and I know how to do the collision detection with the characters using Rectangles, but what I dont know how to do is the collision detection for the maps. What I mean by that is like so the character cant walk over trees or water and that stuff but using rectangles doesnt seem like the best option here. Well to explain what the game maps are gonna look like, here is an example http://i980.photobucket.com/albums/ae287/gordsmash/7-8.jpg Now I could use rectangles to get bounds and stop the player from walking over the trees and water but that would take a lot of them. But is there another easier way to prevent the player from walking over the trees and obstacles besides using Rectangles?

• Create edges in Blender

  - by Mikey

  I've worked with 3DS Max in Uni and am trying to learn Blender. My problem is I know a lot of simple techniques from 3DS max that I'm having trouble translating into Blender. So my question is: Say I have a poly in the middle of a mesh and I want to split it in two. Simply adding an edge between two edges. This would cause a two 5gons either side. It's a simple technique I use every now and then when I want to modify geometry. It's called "Edge connect" in 3DS Max. In Blender the only edge connect method I can find is to create edge loops, not helpful when aiming at low poly iPhone games. Is there an equivalent in blender?

• What's the most important trait of a programmer desired by peer programmers [closed]

  - by greengit

  Questions here talk about most important programming skills someone is supposed to possess, and, a lot of great answers spring up. The answers and the questioners seem mostly interested on qualities related to getting a better job, nailing some interview, things desired by boss or management, or improving your programming abilities. One thing that often gets blown over is the genuine consideration for what traits peers want. They don't much value things like you're one of those 'gets things done' people for the company, or you never miss a deadline, or your code is least painful to review and debug, or you're team player with fantastic leading abilities. They probably care more if you're helpful, are a refreshing person to talk to, you're fun to program in pair with, everybody wants you to review their code, or something of that nature. I, for one, would care that I come off to my peers as a pleasurable programmer to work with, as much as I care about my impression on my boss or management. Is this really significant, and if yes, what are the most desirable traits peers want from each other.
