• Mobile Development Competition

  - by Oscar

  I think this is the correct website to ask this question, if it is not, I am sorry. I want to start learning mobile device development, but I am someone that gets much more motivated when there is some goal to reach. Because of that, I would like to join a competition. I know about Microsoft Imagine Cup, which is a very nice competition. Does anyone knows another mobile development competition with a deadline in the next 6~8 months? I have been googling for it, but I could not find any, maybe someone knows about something that I couldn't find. Thanks for your help :)

• Pair programming business logic with a non-IT person

  - by user1598390

  Have you have any experience in which a non-IT person works with a programmer during the coding process? It's like pair programming, but one person is a non-IT person that knows a lot about the business, maybe a process engineer with math background who knows how things are calculated and can understand non-idiomatic, procedural code. I've found that some procedural, domain-specific languages like PL/SQL are quite understandable by non-IT engineers. These person end up being co-authors of the code and guarantee the correctness of formulas, factors etc. I've found this kind of pair programming quite productive, this kind of engineer user feel they are also "owners" and "authors" of the code and help minimize misunderstanding in the communication process. They even help design the test cases. Is this practice common ? Does it have a name ? Have you had similar experiences ?

• Is Python worth learning? Is it a useful tool?

  - by Kenneth

  I recently had a discussion with a professor of mine on the topic of web development. I had recently decided I would learn python to increase my arsenal of web tools which I mentioned to him at that time. He almost immediately asked why I would waste my time on that. I'm not certain but I think he recently started in on researching and studying web development so he could pick up the web development classes that haven't been taught for a while after the previous professor who taught those classes left. I've heard a lot about python and thought maybe he was mistaken about its usefulness. Is python a useful tool to have? What applications can it be used for? Is it better than other similar alternatives? Does it have useful applications outside of web development as well?

• Python library for scripting (C++ integration)

  - by Edward83

  Please advise me good wrapper/library for python. I need to implement simple scripting in c++ app; Under "good" I mean pretty understandable, well documented, no memory leaking, fast. For creating base interface of GameObject on Python and C++; Your own experience and useful links will be nice!!! I found link about it, but I need more specific within gamedev context. What combinations of libraries you used for python integration into c++? For example about ogre-python it said built using Py++ and Boost.Python library And one more question, maybe someone of you know how Python was integrated into BigWorld engine (it's own port or some library)? Thank you!!!

• How to achieve a Gaussian Blur effect for shadows in LWJGL/Slick2D?

  - by user46883

  I am currently trying to implement shadows into my game, and after a lot of searching in the interwebs I came to the conclusion that drawing hard edged shadows to a low resolution pass combined with a Gaussian blur effect would fit best and make a good compromise between performance and looks - even though theyre not 100% physically accurate. Now my problem is, that I dont really know how to implement the Gaussian blur part. Its not difficult to draw shadows to a low resolutions buffer image and then stretch it which makes it more smooth, but I need to add the Gaussian blur effect. I have searched a lot on that and found some approachs for GLSL, some even here, but none of them really helped it. My game is written in Java using Slick2D/LWJGL and I would appreciate any help or approaches for an algorithm or maybe even an existing library to achieve that effect. Thanks for any help in advance.

• Should a programmer know Linux ?

  - by Maxtor

  I'm a PHP/Python programmer learning Java and C#(.NET). My main OS is windows 7 but I've used Linux and currently dual-booting with Ubuntu. My Linux knowledge however, is pretty limited. I can work with the command line on simple tasks but that's pretty much it. I don't do any shell scripting, don't know very well the most important commands, nor the system in general. My interests are web development, mobile apps and maybe some embedded stuff in the future. Should I get myself familiarized more with Linux ? Even if at the moment I'm not that interested in it? Is it a must for future job positions considering my field of interest? Thank you.

• Thumbnailers of text and ogg files

  - by David López

  I use ubuntu 12.04 and I can see in nautilus thumbnailers of ogg (with embedded artwork) and text files, just like in figure It's a nice feature. I have a slow machine and I've installed Arch with LXDE and pcmanfm. I would like the same thumbnailers, but I can only see a few of them like in the figure I've installed nautilus, thunar, spacefm... and lots of different thumbnailers in my Arch machine, but I haven't be able to see the thumbnailers of text and ogg files. I think that maybe ubuntu uses a patched nautilus version with extended capabilities or something like this. Any idea? Thanks.

• Additional useful skill?

  - by Sergey

  Almost each language has some additional technology or skill or whatever which can work in a pair with it but still be something fresh. For example, Java + Flex. It's a good pair - those who learn Java and want something both useful and new may try Flex. What are "pairs" for the most popular languages(Java, C#, C++, etc.)? PS: Most people advise learning functional programming as an additional skill but this is very fuzzy. They talk about such abstract things as wide programming perspective and other things, but you can hardly say whether these functional skills will be really needed. Yeah, maybe some basics of it can be useful, but serious learning of LISP seems not perspective.

• Codeigniter Open Source Applications for Coding References

  - by Hafizul Amri

  I choose codeigniter to be my first framework to work with. Now I'm looking for open source applications built based on this framework to be my references for good coding practices and standards. From my previous experiences in application development, it was hard for me to maintain, upgrade, or modify existing applications due to my bad coding practices. Do you have any suggestion of application based on codeigniter framework for me to be referred? So that it can help me to write better coding by referring to their good and maybe best coding pratices. Thank you!

• Why don't more games use vector art?

  - by Parris

  It would seem to me that vector art is more efficient in terms of resources/scalability; however, in most cases I have seen artists using bitmap/rasterized art. Is this a limitation put on the artists by the game programmers/designers? As a programmer I think vector art would be more ideal, since it allows for scaling up resolution without having to recreate the art, creating really large graphics or causing graphics to become blurry. The questions: why aren't more people using SVG/AI to create 2D game art? Would it actually be preferred (and who prefers it)? Are bitmap graphics a standard or a limitation (or maybe neither)? Background: I am working on an engine, and I had some kinda cool ideas for vector based graphics; however, I don't want to piss off artists in the future. I guess this is more a question centered around pragmatism and developing games.

• Are there any plans to create a standard based on libunity?

  - by Sebastian Billaudelle

  In the last few month and maybe even years, Ubuntu and Canonical often were criticised for developing software and desktop components without talking to other groups in the free software community. I don't want to comment on this topic, but I see problems arising with creating a "proprietary" solution for displaying indicators and progressbars with a launcher like Unity. In the world of free and open Desktop Environments we often try to standardize parts and libraries or write specifications to increase collaboration between different desktops. We have the instrument of http://freedesktop.org and a lot of specifications are getting implemented by the major Desktop Environments. In this context, proposing a standard for those indicators would be a great step towards better interoperability between desktops. These indicators represent a great feature on the Linux Desktop and I'm sure that other projects like AWN, Docky, etc. would pick them up. With the great market share of Ubuntu, Canonical is in a position to propose it as a standard and encourage projects to implement it. Thank you in advance, Sebastian Billaudelle

• [JOGL] My program is too slow, how can I profile with Eclipse?

  - by nkint

  My simple opengl program is really toooo slow and not fluid. I'm rendering 30 sphere with simple illumination and simple materials. The only complex computing stuff I do is a collision detection between ray-mouse and spheres (that works ok and i do it only in mouseMoved) I'm not using any threads, just an animator to move spheres. How can I profile my jogl project? Or maybe (most probable...) I have some opengl instructions that I don't understand and make render particular accurate (or back face rendering that I don't need or whatever I don't know exactly I'm just entering the opengl world)

• .NET Reflector 7 Released

  - by Paulo Morgado

  This new version fixes a number of bugs and adds support for more high level C# features such as iterator blocks. A new tabbed browsing model was added and Jason Haley's PowerCommands add-in was included as an exploratory step for future versions. To find out more about version 7 just visit http://www.reflector.net/. The release of version 7 also means that the free version of .NET Reflector is no longer available for download. Maybe you can still get one of the give away licenses that Red Gate provided to communities and individuals.

• Toyota's Supply Chain "ran too hot"

  - by [email protected]

  The Feb 28th '10 edition of the Economist had a very informative artical (pg.74) on Toyota's over-stretched supply chain pointing out that they were ' the author of most of its own misfortunes".  James Womack is quoted in the piece on Toyota's rapid expansion 'meant working with a lot of unfamiliar suppliers who didn't have a deep understandin of Toyota's culture.  The majority of the problems almost certainly originated not in the Toyota factories but in those of the supppliers'. One purchasing executive said that it started in mid-2008, when the weaker parts of the supply chain were put under great strain. There is a need for visibility but not always there. Firms need transparancy and speed of communications to make sure defective parts and errors dont reach the customer. It concludes with guidance to manufacturers: "It may be safer not to have all your eggs in one basket, but to have maybe 3 suppliers for major components who can benchmark each other' - Toyota was the peerless exemplar, now seen as an awful warning

• Why my public ip address is different when I visit different website? [closed]

  - by Mett Li

  After I connect to web via pppoe, I visit different website's phpinfo() page, but the result of _SERVER["REMOTE_PORT"] is different. Including some ip address lookup site like www.whatismyip.com, www.apnic.net etc. and gmail's ip location lookup list are all different. Why? Is these different ip address allocated by ISP on different web resources ? Maybe the reason is CDN by my ISP or the website? If the reason is the ip address allocated by ISP on different web resources, the website visitor's ip address may unreal.

• Can the customer be a SCRUM Product Owner in a project?

  - by Morten

  I just had a discussion with a colleague about the Product Owner role: In a project where a customer organization has brought in a sofware developing organization (supplier), can the role of Product Owner be successfully held by the customer organization, or should it always be held by the supplier? I always imagined, that the PO was the supplier organizations guy. The guy that ensured that the customer is happy, and continously fed with new and high-businessvalue functionality, but still an integral part of the developer organization. However, maybe I have viewed the PO role too much like the waterfall project manager. My colleague made me think: If the customer organization is mature and proffessional enough, why not let a person from their camp prioritize the backlog?? That would put the PO role much closer to the business, thus being (in theory) better to assess the business value of backlog items. To me, that is an intriguing thought. But what are the implication of such a setup??? I look forward to your input.

• Scheduling Jobs in SQL Server Express

  As we all know SQL Server 2005 Express is a very powerful free edition of SQL Server 2005. However it does not contain SQL Server Agent service. Because of this scheduling jobs is not possible. So if we want to do this we have to install a free or commercial 3rd party product. This usually isn't allowed due to the security policies of many hosting companies and thus presents a problem. Maybe we want to schedule daily backups, database reindexing, statistics updating, etc. This is why I wanted to have a solution based only on SQL Server 2005 Express and not dependent on the hosting company. And of course there is one based on our old friend the Service Broker.

• dash all over my unity in asus k45vd

  - by sajjad

  I installed ubuntu 13.10 in asus k45vd laptop. sometimes when I'm working with my laptop I see dashes all over my screen(showing them takes maybe less than one secconds so it's difficult to take screenshot.) This problem just is in unity in other desktops which I installed like xfce4, kde, gnome-shell there isn't this problem. in ubuntu 13.04 there was this problem in my laptop too, and I tested ubuntu in another laptop asus k55vd there is this problem in that laptop too. I thought this a unity bug in asus kxxvd series! is there any solution for this problem?

• Level Design V.S. Modeler

  - by Ecurbed

  From what I understand being a level designer and a character/environment/object/etc Modeler are two different jobs, yet sometimes it feels like a Modeler can also do the job of the level designer. I know this also depends on the scale of the game. For small games maybe they are one and the same, but for bigger games they become two different jobs. I understand a background in some modeling could not hurt when it comes to level design, but the question I have is: Do jobs prefer people who can model for level designing? This way they can kill two birds with one stone and have someone to create the assets and design the level. What is your opinion of the training? Does level design contain skill sets that make them completely different from what a modeler can do, or is this an easy transition for a modeler to become a level designer? Can you be a bad level designer but a good modeler and vice versa?

• Does seeding torrents affect the harddisk RAM caching?

  - by satuon

  I've downloaded a lot of torrent files and while I'm seeding them, I've noticed that very often when I start the browser it's slow and the hard disk activity indicator is on. Usually when I start a program it gets cached in RAM and starting it again is very quick, and I have 3 GB of RAM so usually it stays cached nearly forever. But when my torrent client is seeding it seems that after an hour programs that I ran are no longer cached in RAM. I was thinking maybe it's because of the disk reads which the torrent client performs are cached and fill up RAM eventually. But I don't think they need to be, as they are read only once and are unlikely to be read again soon. So my questions are - is this the way I think, and if so is it possible in principle to prevent the disk reads from being cached? I can try to edit the source code of the program.

• What Web Technology to use?

  - by Sven

  Hey guys, I would like to start a project and I am concerning what kind of programming language/web framework to use. There is not that much logic involved. It's about a community-page with a lot of users(not that much at the beginning but I would like to be ready to welcome a lot), that should be able to communicate through private messages and a forum and there will be a lot of content (news, articles) to consume. I also want to provide several authorization settings to provide some content for only specific people. In fact it's about a content management system, but I want to design it functionally myself. And I want to use some external APIs. The only website I can think of with almost similar functionality is pokerstrategy.com. I looked up their job offers and it seems like they use java and php Maybe you guys can give me your thoughts. What would you use to encounter that requirements and how would you apprach? Thank you

• Different database for Membership and our web data or use just one?

  - by Jesus Rodriguez

  Is better to keep our Membership stuff on the DefaultConnection and create another connection (another database) for our data? Or just one database for all? If I have a MyAppContext and I want migrations for that context, It seems that I cannot have migrations for UserContext (In other words, I can just migrate one context) So, having two different databases I can migrate or the users (maybe membership migration is weird) or the web data. Or, I can mix the UserContext and MyAppContext in one UserAndAppContext and migrate all in one place, but this mixing also seems weird. What's the normal way to do this, one or two databases and what should be migrated?
