• Your experience with haxe and other languages that compile to PHP?

  - by Kim

  I would like to hear oppinions from people who have used a language that compiles to php. One such language I know is Haxe. Other ones I've read about are Kira and Pharen. How well do these languages integrate with PHP? Is it relatively easy to write a plugin for a PHP CMS in them? How mature are their implementations and tools? Would you recommend them to someone who has to use a php cms but hates php?

• Thoughts on Development using Virtual Machines

  - by J_A_X

  I'll be working as a development lead for a startup and I've suggested that we use VMs for development. I'm not talking about each developer having a desktop with VMs for testing/development, I mean having a server rack where all VMs are managed and have the developers work from a microPC (ChromeOS anyone?) locally, or even remotely from their home computer. To me, the benefits are the fact that it's extremely scalable, cheaper in the long run, easier to manage and that we utilize the hardware its maximum potential. As for cons, I can't think of any particular showstoppers other than we'll need someone to setup/maintain said setup. I was hoping that some of you might of had a similar setup at your place of employment and be able to weight in with your opinions. Thanks.

• Rotate view matrix based on touch coordinates

  - by user1055947

  I'm working on an Android game where I need to rotate the camera around the origin based on the user dragging their finger. My view matrix has initial position of sitting on the negative z and facing origin. I have succeeded in moving the camera through rotation left or right, up or down based on the user dragging the finger, but my problem is obviously that after I drag my finger up/down and rotate say 90 degrees so my intial position of -z is now +y and still facing origin, if I drag my finger left/right I want to rotate from +y to +x, but what happens is it rotates around the pole +y. This is to be expected as I am mapping 2D touch drag coords to 3D space, but I dont know where to start trying to do what I want. Perhaps someone can point me in the right direction, I've been googling for a while now but I don't know what I want to do is called! Edit __ What I was looking for is called an ArcBall, google it for lots of info on it.

• Converting 3 axis vectors to a rotation matrix

  - by user38858

  I am trying to get a rotation matrix (in 3dsmax) from 3 vectors that form an axis (all 3 vectors are aligned by 90 degrees each other) Somewhere I read that I could build a rotation matrix just by inserting in every row one vector at a time (source: http://renderdan.blogspot.cz/2006/05/rotation-matrix-from-axis-vectors.html) So, I built a matrix with these example vectors x-axis : [-0.194624,-0.23715,-0.951778] y-axis : [-0.773012,0.634392,0] z-axis : [-0.6038,-0.735735,0.306788] But for some reason, if I try to convert this matrix to eulerangles, I receive this rotation: (eulerAngles 47.7284 6.12831 36.8263) ... which is totally wrong, and doesn't align to my 3 vectors at all. I know that rotation is quite difficult to understand, may someone shed some light? :)

• Self Documenting Code Vs. Commented Code

  - by Phill

  I had a search but didn't find what I was looking for, please feel free to link me if this question has already being asked. Earlier this month this post was made: http://net.tutsplus.com/tutorials/php/why-youre-a-bad-php-programmer/ Basically to sum it up, you're a bad programmer if you don't write comments. My personal opinion is that code should be descriptive and mostly not require comment's unless the code cannot be self describing. In the example given // Get the extension off the image filename $pieces = explode('.', $image_name); $extension = array_pop($pieces); The author said this code should be given a comment, my personal opinion is the code should be a function call that is descriptive: $extension = GetFileExtension($image_filename); However in the comments someone actually made just that suggestion: http://net.tutsplus.com/tutorials/php/why-youre-a-bad-php-programmer/comment-page-2/#comment-357130 The author responded by saying the commenter was "one of those people", i.e, a bad programmer. What are everyone elses views on Self Describing Code vs Commenting Code?

• What tasks should an Architect NOT do or limit to be effective?

  - by GBH

  There are plenty of questions/answers about what an architect does, but what should someone in an Architect role NOT do? What are the boundaries/limits to maintain to be an effective Architect? I'm thinking here of Architect vs Developer and Architect vs Project Manager For example, I'm finding myself in a role where my title is Architect but I am also the coding/development lead and project manager on multiple small enterprise projects. I'm struggling with all the task switching and now I want to limit task switching. Trying to wear every hat just isn't working. What tasks should an Architect not do at all? What tasks should an Architect limit? I do think an Architect needs to keep coding, but how to define an appropriate limit for coding work?

• The understanding of flight search engine

  - by Jens Jensen

  Today I just discovered a search engine website who offered a service to enter your departure destination, and then search for which possible destinations you can have for the cheapest price. This is very nice to use, if one wants to flight somewhere but doesn't know which "good deals" are available. This is the site: http://www.kayak.com/explore/ Can someone explain to me, which programs are (mostly) used, and summarize how to make this sort of search engine. I think this is very interesting but unfortunately there are not shown all the possible flight tickets and therefore I think this project could be improved.

• Is the C programming language still used?

  - by Pankaj Upadhyay

  I am a C# programmer, and most of my development is for websites along with a few Windows application. As far as C goes, I haven't used it in a long time, as there was no need to. It came to me as a surprise when one of my friends said that she needs to learn C for testing jobs, while I was helping her learn C#. I figured that someone would only learn C for testing only if there is development done in C. In my knowledge, all the development related to COM and hardware design are also done in C++. Therefore, learning C doesn't make sense if you need to use C++. I also don't believe in historic significance, so why waste time and money in learning C? Is C is still used in any kind of new software development or anything else?

• 11.10 AMD64 alternate installer has broken packages?

  - by Ibrahim

  I'm installing Ubuntu 11.10 from the alternate install ISO because I need to use LVM. Unfortunately, at some point the installer fails because it can't install libpurple0 and ubuntu-desktop because they depend on libsasl2-modules but it's not installable somehow. It also has the same error for xserver-xorg-video-all but I think I could probably live without that one. Kind of annoying that this is broken, I'm guessing maybe if I had internet it would work but right now I'm on a campus network with a captive portal so I can't actually get a network connection without using a browser to log in. Just thought someone should know or maybe I'm doing something wrong. I'm going to try installing 11.04 alternate and then upgrading I guess.

• Will rewriting your .htaccess to 404 to return search results from your site negatively effect your ranking in Google?

  - by leeand00

  Depending on the type of site that you are running, it may or may not be advantageous to display search results instead of a 404 page, when someone visits a non-existent page on your site. I believe that the site I've been maintaining recently would benefit from this as it is the site of a publication. With a publication the more people you can get to read your site the better. But after reading up on how Google ranks the "quality" of your site, where you will appear in SERPs, based on how much the meta text of a page relates to the content of the page, I have to wonder if making a 404 page link to the search results would harm the "quality" of your site in Google eyes.

• What options do I have for game hosting.

  - by Jonathan Kaufman

  DISCLAIMER: I know this question starts to leave development island but it is very game development related and still think this is the best place. I see many free MMOs/online desktop client games out there. I am baffled at the ability to fund such. I don't mind hosting myself but would at least like to have someone host a matchmaking service. If these indie devs really are pouring money down the server drain then I'm screwed but if some one can "learn me" :) some alternatives I would greatly appreciate it.

• Any good tutorials all this web programming stuff for a GUI person? [closed]

  - by supercheetah

  For some reason, I am having a hard time understanding all this web programming stuff--from AJAX to JSON, etc. I've got plenty of experience programming GUIs. I'm currently working on a project in Python, and I thought that maybe I could just use PyJS (since it's GWT for Python, it uses an API that's very familiar to experienced GUI programmers like myself) to compile it with a Javascript interface on top, but alas, the compiler gave me a spectacular failure. It's obviously not meant to handle much of any Python beyond itself, and some of the core Python library. It would have been nice if it could, but I will admit, it would have been the lazy way to do it. I tried to learn Django, but for some reason, I'm just having a hard time understanding the tutorial on their website, and what it's all doing. Maybe it's not the best framework to learn, perhaps? Anyway, does anyone have a good primer/tutorial explaining all this stuff, especially for Python, and especially for someone coming from a GUI background?

• How *not* to handle a compensation step on failure in an SSIS package

  - by James Luetkehoelter

  Just stumbed across this where I'm working.

• Ubuntu apt-get install linux-image

  - by Karl Kloppenborg

  I'd like someone to enlighten me as to what exactly goes on with aptitude when I want a kernel. As we all know, there's pretty much the following kernel option: linux-image-generic linux-image-server linux-image-virtual This morning I did an install and it had linux-image-generic on it, so I ran the following: apt-get -y remove linux-image-* This removed all my kernels as expected, I followed suit with running: apt-get install linux-image-virtual Says I've installed linux-image-server!? Am I missing something here, because I checked twice and it did it twice, however if I manually select a kernel (in my instance I used: linux-image-2.6.35-30-virtual) it will install linux-image-virtual. This seems rather strange to me? Details: Running Ubuntu 9.10 Am I missing something? :)

• How do you react to non-programmers with ideas of 'The Next Big Thing' ?

  - by jiceo

  Recently and quite often, people with no programming background come and say they have this great idea that can be the next big thing and that the idea(s) is worth a fortune by itself. Then as they know I'm a programmer, they ask me if I'm willing to "code it up" for them or find someone willing to do it for next to nothing. Judging from the enthusiasm, it's like they're drunk on their idea and that that by itself is the most important thing, but they just need a programmer. My response to them, depending on my mood and their general attitude towards what we do, is something along the lines of: "Having the core of an idea is one thing. Developing it to the point that it becomes a platform that changes the world in which it lives is another, and you're going to be willing to pay proportionately to how big you think your idea is worth." Have you been approached by these business type entrepreneurs (with no technical/developer's knowledge) with such a proposal and how do you react to them?

• HD flash video lagging on LG R400

  - by dhojgaard

  I'm installing Ubuntu on my friends laptop. An LG R400 with ATI Mobility Radeon X2300 graphics drivers. On Windows Vista which runs pretty slow the HD flash videos 1080p on Youtube vimeo and other places work with no problems, but on Ubuntu i can not really play videos above 480p Above that they are lagging. That annoys me because i know he will use them, and how am i supposed to convince him that Ubuntu is the way to go if it can not play the videos that windows vista can? Unity 3d is working fine so i think the graphics drivers is working, and when i download the hd videos and play as mp4 in vlc they also work fine. lspci -nn | grep VGA shows the following: 01:00.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI Mobility Radeon X2300 Hope that someone can help me convince my friend that Ubuntu is rocking!

• Switch encoding of terminal with a command

  - by Tomas Lycken

  One of the servers I quite often ssh to uses western encoding instead of utf-8 (and there's no way I can change that). I've started writing a bash script to connect to this server, so I won't have to type out the entire address every time, but I would like to improve this script so it also changes the encoding of the terminal window correctly. The change I need to do can be performed using the mouse by navigating to "Terminal"-"Set Character Encoding..."-"Western (ISO-8859-1)". Is there a terminal command that does the same thing, for the current terminal window/screen? To clarify: I'm not interested in ways of switching the locale of the system on the remote site - that system is administered by someone else, and I have no idea what stuff might depend on the latin-1 encoding there. What I want to do is to let this terminal window on my side switch character encoding to the above mentioned, in the same way I can do with my mouse and the menus.

• Why isn't Java more widely used for game development?

  - by Anto

  I'm not a game developer or anything, but I know that Java is not very widely used for game development. Java should be fast enough for most games, so where's the catch? I can think of some reasons: Lack of game developers with expertice in Java Lack of good game development frameworks Programmers don't want to accept Java as a games programming language. Most only accept C++ as that? No support for game consoles (though the PC market still exists) It could of course be something else. Could someone who knows the business better than me explain why Java isn't getting momentum when it comes to game development?

• How would you explain that software engineering is more specialized than other engineering fields?

  - by Spencer K

  I work with someone who insists that any good software engineer can develop in any software technology, and experience in a particular technology doesn't matter to building good software. His analogy was that you don't have to have knowledge of the product being built to know how to build an assembly line that manufactures said product. In a way it's a compliment to be viewed with an eye such that "if you're good, you're good at everything", but in a way it also trivializes the profession, as in "Codemonkey, go sling code". Without experience in certain software frameworks, you can get in trouble fast, and that's important. I tried explaining this, but he didn't buy it. Any different views or thoughts on this to help explain that my experience in one thing, doesn't translate to all things?

• Are programmers tied to their code?

  - by Jason

  Assuming you are working for a company or in a team of developers, is the code bound to the person who did it? When someone develops a particular functionnality or an area of the application, is this person the only one who can, is allowed or is just able to make changes to it? I personnally think that a well-done piece of code or program should be easily modified by any programmers, but what about what you see in your environment? At my work, I'd say that the majority of the code can be modified by anyone (that's what coding standards are for right?). There are some things though that are 'property' of some coworkers like the module that handles the pay or some important functionality of the production module (we are developing an ERP system). What about your work place? Am I the only one living this?

• DNS configuration to force root domain to www

  - by kolosy

  we have an app running on heroku. the dns setup is like this: A record for domain.com - heroku front end ip addresses CNAME for www.domain.com - specific host name for our app provided by heroku we also have an SSL cert for www.domain.com. the issue is that if someone goes to https://domain.com/secure_stuff, they will get heroku's SSL cert, instead of ours, causing lots of fear. We can do things on our end to make sure that all of our URLs point to https://www.domain.com, but it still won't solve this specific issue. is there a way to configure the DNS record to redirect all root domain traffic to the www subdomain?
