• Ogre3D : seeking advices about game files management

  - by Tibor

  I'm working on a new game, and its related level editor, based on Ogre3D. I was thinking about how i could manage the game files, knowing that Ogre use .mesh files for models, .material for materials/texture information etc... . At first i thought about a common .zip folder decompressed at runtime (the same way Torchlight and Ogre samples do). But this way the game assets become a monolithic archive, loading takes time, and could be difficult to eventually patch them. So, let's say i have a game object named "Cube" i want to load in my program. Going for modularity, what if i create a compressed file (using zlib compression routines) named Cube.extname, containing its sub-files Cube.mesh, Cube.material and so on ? Are there any alternatives or should i stick with compressed objects? PS: Just to clear things, the answer is unrelated to my program code, at the moment i'm using "resources.cfg" pointing to the OgreSDK media directory.

• CS subjects that an undergraduate must know.

  - by Karl

  In college, I was never interested in theory. I never read it. No matter how much I tried, I was unable to read stuff and not know what was actually happening practically. Like for example, in my course on automata theory, my professor told me everything possibly related to the mathematical aspect of it, but not even once did he mention where it would be used practically. This is just an example. I managed to pass my college and interned with a company also, where I did a project and thankfully they didn't bother about my grades, as they were above average. Now, I am interested in knowing what subjects should a CS student must absolutely and positively be aware of? Subjects that can have relevance in the industry. This is because I have some free time on my hands and it would help me better to have a good understanding of them. What are your suggestions? Like for one, algorithms is one subject.

• Why are software schedules so hard to define?

  - by 0A0D

  It seems that, in my experience, getting us engineers to accurately estimate and determine tasks to be completed is like pulling teeth. Rather than just giving a swag estimate of 2-3 weeks or 3-6 months... what is the simplest way to define software schedules so they are not so painful to define? For instance, customer A wants a feature by 02/01/2011. How do you schedule time to implement this feature knowing that other bug fixes may be needed along the way and take up additional engineering time?

• Will Apple abandon OpenCL?

  - by John

  I am developing OpenCL applications, amongst others for MacOS. The new Macbook pro 13 inch comes with an Intel HD Graphics 3000 card so it seams reasonable to assume all their mainstream computers like Macbook and Mac mini will also come out with this Intel graphics card soon. OpenCL is not available for Intel graphics cards. Intel having a terrible reputation in developing graphics drivers and Apple knowing this makes me wonder Apple is abandoning OpenCL already again. Especially considering OpenCL should run anywhere, not only on high end systems. Developing applications only for the high end Macs with dedicated graphics hardware or for previous generation hardware with the Geforce 320M would not be a feasible option for me. Does anybody have any thoughts on this?

• Unable to mount samsung galaxy S3 via USB

  - by dez93_2000

  Connecting as either MTP or PTP: neither allows one to see pictures saved as default by phone camera to DCIM folder on external SD card. Similar problems with previous models (e.g. S2) were solvable by 'usb utilities' in wireless & networking settings, but this is no longer present. Other suggestions have mentioned uninstalling various libraries... but i don't wanna just start cutting stuff without knowing it'll help. Any thoughts? Seems like a pretty epic fail from google & samsung. There's not even a linux section on the relevant google site... despite android's usb driver being part of the linux kernel which powers android. Boo!

• What is the best way to become a professional in PHP and Website Building?

  - by Mr.TAMER

  I would like to become a professional in php, I have learned nearly all about the language syntax and concepts and I have a good knowledge in C and C++, which made it easier to become familiar with PHP. (Of course, I learned MySql too.) But I don't feel like being able to build even a little good website of my own! It looks like PHP is all about knowing lots of functions and using them, while in fact I don't think it's like that, is it? How can I become a professional in PHP and Website Building? I would do anything and spend whatever amount of time required for that. EDIT I've also a very good knowledge in HTML and a normal knowledge in CSS and JavaScript. Sorry for not mentioning that, I just thought it was implicitly included.

• How to recover data from NTFS partition that was made into a Swap partition?

  - by Raghav Mehta

  I have extremely important stuff on my windows partition which during the ubuntu 10.10 installation,when it said that I should create something called swap space, I selected it to be a swap space (without even knowing what it actually meant) The Grub2 doesn't show up so I don't get a choice to boot Ubuntu or Windows. I don't get my windows partition as a removable device in Ubuntu either. When I go to disk utility and select the sda2 (i.e.. my windows partition) and click edit partition and select HPFS/NTFS for the type and tick bootable and click OK the small processing sign keep on rotating on the bottom right of the sda2 in the chart and after about 10 to 15 minutes it gives an unknown error and thus, I am still unable to use my windows. I am even worse than a beginner who doesn't know a thing about Ubuntu so please be patient and help me out.

• How much time takes to a new language like D to become popular? [closed]

  - by Adrián Pérez

  I was reading about new languages for me to learn and I find very good comments about D, like it's the new C or what C++ should have been. Knowing that many people say wonders about the language, I'm wondering how much time usually takes to a language to become popular. This is, having libraries ported or written natively for this language and being used in serious software development. I have read about the history of Java, and Python to figure it out, but may be they are too high level complexity to say their development could take the same time as will take for D.

• What do you need to know to get a job as a web developer

  - by Alex Foster

  What do you need to know to at the very least get your foot in the door? We're assuming for someone who doesn't have a college degree (yet) but will eventually get one. My guess is html, css, javascript, and php, and photoshop and dreamweaver, and sql. And being familiar with using a web host to have sites live, like knowing how to use cpanel. It's probably a very inaccurate and narrow guess but that's what i think right now. I don't know exactly.

• Suggestions on Calculating Advertising Rates [closed]

  - by Jonathan Wood

  Possible Duplicate: How do I set a price for advertising on my website? I recently launched a new developer website, Black Belt Coder. The site is only seeing about 150 visitors per day but, given that it's only been live two months, I feel I'm off to a good start. I'd like to start monetizing the site as soon as possible but consider AdSense and other programs largely a waste of time. I'd like to deal directly with the advertisers but have no idea what to charge. Are there any guidelines for determining advertising rates based on visitors or page views? I don't expect to do PPC. I want to charge a the time period for banner ads, knowing that advertisers will be keeping an eye on the number of clicks.

• Designing a game - Where to start?

  - by OghmaOsiris

  A friend of mine and I are planning a game together to work on in our free time. It's not an extensive game, but it's not a simple one either. He's working on the story behind the game while I'm working on the graphics and code. I don't really know where to start with the game. We know what the basic type of game it's going to be and how it would be played, but I'm having a hard time of actually knowing where to begin. I have Xcode open but I don't really even know what I should be designing first. What is some advice for this writer's block? Where is a good place to start with a game? Should I design all the graphics and layout before even touching Xcode? Should I program the things I know I'll have difficulty with first before getting to the easy stuff?

• The Gates Books&ndash;Finished

  - by MarkPearl

  Today I can finally say that I finished both of my Bill Gates books that had been lying on the shelf for several years. The books were… The Road Ahead (1995) Business @ the Speed of Thought (1999) I enjoyed “The Road Ahead”, purely because it was fun to read about someone looking into the future at technology, while I could read it looking at the past. In fact I was quite impressed with how much he got right and it was also nice to remember “The good old days”. Business @ the Speed of Thought was a harder read for me. The book still had some good insights, but was tough going at times (possibly because it was several hundred more pages than the first). All that being said, I can now finally place them back on the shelf knowing that they have been read.

• graphical interface when using assembly language

  - by Hellbent

  Im looking to use assembly language to make a great game, not just an average game but a really great game. I want to learn a framework to use in assembly. I know thats not possible without learning the framework in c first. So im thinking of learning sdl in c and then learn, teach myself, how to interpret the program and run it as assembly language code which shouldnt be that hard. Then i will have a window and some graphics routines to display the game while using assembly to code everything in. I need to spend some time learning sdl and then some more time learning how to code all those statements using assembly while calling c functions and knowing what registers returned calls use and what they leave etc. My question is , Is this a good way to go or is there something better to get a graphical window display using assembly language? Regards HellBent

• How do I avoid "Developer's Bad Optimization Intuition"?

  - by Mona

  I saw on a article that put forth this statement: Developers love to optimize code and with good reason. It is so satisfying and fun. But knowing when to optimize is far more important. Unfortunately, developers generally have horrible intuition about where the performance problems in an application will actually be. How can a developer avoid this bad intuition? Are there good tools to find which parts of your code really need optimization (for Java)? Do you know of some articles, tips, or good reads on this subject?

• Managing time for success in the industry? [closed]

  - by nvillec

  So about a year ago I decided to pursue programming, specifically game development, as a career. I've always been a pretty avid gamer, from chucking turnips at Shy Guys' faces in the 90s, to downing Heroic Deathwing last week. Just recently though, I've been spending a LOT of time playing games and it's starting to show in my programming classes. Yesterday after a discouraging exam, I put my foot down and vowed to myself to keep the gaming:coding ratio in favor of the one that will hopefully pay the bills later on. I realize that knowing games well is a key part of being a good developer, but as I've been recently shown, there's a threshold of pixelated indulgence that must not be crossed if I'm ever going to land my dream job. I'm assuming many of you are quite enthusiastic about games as well. What advice would you give an aspiring programmer regarding time management? Thanks!! (Also, I'm brand new to Stack Exchange...if this belongs somewhere else, I'm happy to move it)

• Google Sites page never shows up in Google Search organic results?

  - by gus

  I use Google Sites (i.e.: https://sites.google.com/site/EXAMPLE/ ) as a convenient way to maintain up-to-date info on several residential properties, info that's often requested by my property agents, its been around for about 1 year, but I still can never get it to appear in organic Google search results or Bing, even if I search the specific keywords such as the street names. I submitted the URL manually to search engines, knowing that my Sites page probably has very few incoming links. Is this expected behavior? The content of my page has simple formatted text, and outgoing links to Picasa/G+/imgur photo albums. Am I doing something wrong or do all GoogleSites pages have poor organic search rank? Thank you very much.

• Is it a good idea to simplify an character -driven game engine to the point it's unnecessary to learn scripting/programming ?

  - by jokoon

  I remember, and I still think, that one cannot even make a prototyped 3D game to test just simple behaviors without using gigantic tools like unity or knowing extensive C++ programming, design pattern, a decent or basic 3D engine, etc. Now I'm wondering, since I know programming, that I'm still more lucky that the ones who need to learn programming prior to know how to make something: even scripted engines such as unity are not for kids, and to my sense they tend to dictate their ways of doing things, which is not the case with engine like ogre or irrlicht. I remember toying a little with the blender game engine, it was possible to link states or something I don't remember very well. Now I'm thinking that character driven games occupies a big part of the game market. Do you think it is a good idea to make a character-controlled oriented game engine which allows only to build AI instead of anything else ?

• What do you use to organize your team knowledge?

  - by Stefano Verna

  Last year, me and three good old friends of mine founded a small web/mobile development team. Things are going pretty well. We're learning a lot, and new people are joining the group. Keeping knowledge always updated and in-sync is vital for us. Long emails threads are simply not the way to go for us: too dispersing and confusing, and hard to retrieve after a while. How your team manages and organizes common knowledge? How do you collect and share useful resources (articles, links, libraries, etc) inside your team? Update: Thanks for the feedback. More than using a wiki to share team common procedures or informations, I'd like to share external links, articles, code libraries, and be able to comment them easily within my team. I was particularly interested in knowing if you're aware of any way/webservice to share a reading list with a team. I mean, something like Readitlater/Instapaper, but for teams, maybe with some stats available, like "# of coworkers who read it".

• what knowledge would I need to make a good simulation games

  - by Skeith

  I have an idea for a game like theme park but don't know how simulation games are made. I am not some noob on his first game so I appreciated constructive answers instead of "its hard, don't do it". What I want is to know how simulation game mechanics are put together. I figure it would be heaver on the AI than normal games and not knowing much about AI would like to know some programming techniques I should look into for this style game. specific techniques please not just a book on ai. what sort of architecture would be used? I guess it would have some sort of probability engine with pre designed events that are triggered based on the AI state. Would it use a FSM or be purely event driven ? Any information on how a sims game functions would be cool.

• Get phone number of (via mobile networks) browsing mobile device

  - by TrialUser

  I recently figured out, that the web site of my phone provider (mobile) mysteriously identifies me and automatically logs me into my account when I'm accessing with my android phone, as if it knew my phone number. (I used several browsers. When I'm using the phone as WLAN hotspot and access the same site from another device that doesn't happen.) How does my phone provider do that? On the one hand, as a programmer, I'd like to be able to do that too, but on the other hand, as a user, I'm kind of scared. What information do they have, such that they (believe they) are able to identify me just by my device? I hope this question isn't completely inappropriate for this site; feel free to add better tags — it's hard to find the right ones without knowing the Webmasters site at all.

• How can you predict the time it will take for two processes in two different machines in a cluster to communicate?

  - by Dokkat

  I am trying to develop a computing application which needs a lot of memory (500gb). Buying a single machine for that is overly expensive. I can, though, buy ~100 small instances on Digital Ocean or similar, divide the memory in blocks and use TCP to emulate shared memory between the instances. Now, my question is: how can I measure/predict the time it will take for two processes in two different machines like that to share information, in comparison to IPC and shared memory? Are there rules of thumb? I don't want exact values, but knowing more or less how much faster one is would be very helpful in visualising the feasibility of this approach.
