  • 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?

  • Were you a good programmer when you first left university?

    - by dustyprogrammer
    I recently graduated, from university. I have since then joined a development team where I am by far the least experienced developer, with maybe with a couple work terms under my belt, meanwhile the rest of the team is rocking 5-10 years experience. I am/was a very good student and a pretty good programmer when it came to bottled assignments and tests. I have worked on some projects with success. But now I working with a much bigger code-base, and the learning curve is much higher... I was wondering how many other developers started out their careers in teams and left like they sucked. When does this change? How can I speed up the process? My seniors are helping me but I want to be great and show my value now. I don't to start a flame war, this is just a question I have been having and I was hoping to get some advice from other experienced developers, as well as other beginners like me.

  • Can i make money with my Android Engine or should I focus on game-making?

    - by Roger Travis
    I have dedicated past few month to developing my own android 2d engine. You can see its description, demo and tutorials here http://www.aboxengine.com/ ( jar files will be up in a day or two ). While working on the engine I believed it to be better then most available alternatives ( such as andengine, etc. ) and that people would love to use it in their games and, hopefully, would give me some royalties. Yet as I started posting about my engine on other forums, it start looking like people are only interested in free/opensource engines. Based on your experience, what do you think, is there some way for me to make money with that engine or should I forget about selling it and more focus on making games with it myself? Thanks!

  • Implementation of Race Game Tree

    - by Mert Toka
    I build a racing game right in OpenGL using Glut, and I'm a bit lost in all the details. First of all, any suggestions as a road map would be more than great. So far what I thought is this: Tree implementation for transformations. Simulated dynamics.(*) Octree implementation for collusion detection. Actual collusion detection.(*) Modelling in Maya and export them as .OBJs. Polishing the game with GLSL or something like that for graphics quality. (*): I am not sure the order of these two. So I started with the simulated dynamics without tree, and it turned out to be a huge chaos for me. Is there any way you can think of such that could help me to build such tree to use in racing game? I thought something like this but I have no idea how to implement it. Reds are static, yellows are dynamic nodes

  • Easy to use cross-platform 3D engines for C++ game development?

    - by davr
    I want to try my hand at writing a 3D game. However I don't want to start at such a low level of drawing individual triangles and writing my own 3D object loader and so on. I've heard of things like Irrlicht, Crystal Space 3D, and Cafu, but I don't have any experience with any of them. I'm looking for suggestions from people who have experience with these or other engines on which ones are well written, and are easy to get started using, without having to learn a ton of 3D math theory and how GPU's work internally.

  • Web development starting a career [closed]

    - by user985482
    Hi I am in the 3rd and last year at college of informatics and I am interested to follow a career in web development when I finish(2 more months). From what I understand this days to get hired you need to be able to know a variety of technologies at least that is the case in Romania.Most of the jobs I have seen even at entry level asks you to know the following: HTML/CSS Javascript , a framework preferable jQuery , Ajax a server side language in my case PHP and a framework SQL and an RDBMS in my case MySql a CMS in my case Wordpress My question is how well should me or anyone looking to get hired as a web developer for there first job should we know this technologies in order to get hired and what else should we aim to learn to have a better chance of getting hired. I don't know if the question is right for this forum but I believe that this could help many of the students and anyone who is taking an interest in web development to know what they should expect from there employers when they try to find work.

  • Microsoft Patches Bugs, Improves Visual Studio 2012

    First, let's talk about the bug patches. Programs getting fixes include Windows, Internet Explorer, Office, the .NET Framework, Microsoft Dynamics AX and Microsoft Visual Basic. You can read the full security advisory. Out of the seven bulletins containing the fixes, three were deemed critical, which means a hacker could exploit an unpatched system by remotely executing malicious code. The remaining four were dubbed important; if exploited, they could give an attacker elevated privileges. Multiple versions of the Windows operating system and Internet Explorer should receive these patches....

  • Plymouth did not install properly

    - by David Starkey
    I was installing the plymouth manager in hopes of making a custom loading screen. While the terminal was working, my computer unexpectedly powered off. I can open up the manager and it appears to do what it is supposed to (minus the fact that I can't make my own theme) and the screen only shows on powering down. Anyway, all of the advice I have seen so far have resulted in errors and nothing getting fixed. I do not have permissions to simply select the folder and delete it for some reason and I have not been able to find out how to grant myself those permissions. I guess my question then is how do I get rid of the plymouth manager so I can reinstall it properly? Already tried: -Installation - http://www.noobslab.com/2011/11/install-plymouth-manager-and-change.html -Removal - How to remove Plymouth Boot Animation manager and keep the default boot screen -Permissions - How do I change my user permissions to edit /etc/apt/sources.list? -Theming Guide - http://brej.org/blog/?p=158

    I'm really new to linux, and I just installed mythbuntu to a standalone pc, it's all installed ok and I've logged on, and started the setup but I'm having issues. I select language ok, the next screen is database setup, select next but it says can't connect to server and I just loop back. I've done some googling and checked the mysql database password and that is correct, I've also checked that my username belongs to myth tv and it does. Can anyone help? I've tried reinstalling but it doesn't change. Many thanks.

  • Apache redircting when it shouldnt

    - by Ivan Moldavi
    I have inherited a LAMP server with a lot of customization. I want to enable mod_status in apache to get some monitoring of apache started. Problem is, with mod_status enabled in the httpd.conf, I am not allowed to travel to the http://"serverIP"/server-status URL because apache is redirecting me to a 'landing page'. If I type any invalid URL for the server, it redirects to this page, all error document pages have been hashed out from the httpd.conf. Any assistance to where this has may have been configured or if there is a way to override it so I can get to the url http://"serverIP"/server-status ?

  • How to Automatically Backup Your Gmail Attachments With IFTTT

    - by Mark Wilson
    When it comes to getting things done quickly, automation is the name of the game. We’ve looked at IFTTT before, and a new batch of updates has introduced a number of options that can be used to automatically do things with files that are sent to your Gmail address. What could this be used for? Well the most obvious starting point is to simply create a backup of any files that you receive via email. This is useful if you find that you often reach the size limit for your inbox as it enables you to delete emails without having to worry about losing the associated files. Start by paying a visit to the IFTTT website and then either sign into an existing account or create a new one.

  • iPhone image asset recommended resolution/dpi/format

    - by Matthew
    I'm learning iPhone development and a friend will be doing the graphics/animation. I'll be using cocos2d most likely (if that matters). My friend wants to get started on the graphics, and I don't know what image resolution or dpi or formats are recommended. This probably depends on if something is a background vs. a small character. Also, I know I read something about using @2x in image file names to support high res iphone screens. Does cocos2d prefer a different way? Or is this not something to worry about at this point? What should I know before they start working on the graphics?

  • Thunderbird 16.0.1 filling disk space

    - by Kris
    I'm on Ubuntu 12.04 with Thunderbird 16.0.1 and Kernel 3.6.0-030600rc4-generic. I used Thunderbird for quite a while and never had any problems with it. But now it seems to fill up my disk space very fast: watch -n 1 df -h . so Ubuntu started giving out warnings. First I removed some files but not much later it had filled up around 600 MB. It eats around 50 MB/min while I just download 10 emails or so via IMAP. This behaviour is new and seems to be some kind of bug. I don't want to delete my old mails, so what else could I do?

  • Game Maker Studio Gravity Problems

    - by Dusty
    I've started messing around with Game Maker Studio. The problem I'm having is trying to get a gravity code for orbiting. Here's how i did it in XNA foreach (GravItem Item in StarSystem.ActiveItems.OfType<GravItem>()) { if (this != Item) { Velocity += (10 * Vector2.Normalize(Item.Position - this.Position * (this.Mass * Item.Mass) / (Vector2.DistanceSquared(this.Position, Item.Position)) / (this.Mass)); } } Simple and works well, things or bit and everything is nice. but in Game maker i don't have the luxury of Vector2's or a For-each loop to loop threw all the objects that have a mass. I've tried a few different things but nothing seems to work distance = distance_to_object(obj_moon); //--Gravity hspeed += (0.5 * (distance) * (Mass * obj_moon.Mass) / (sqr(distance)) / Mass) vspeed += (0.5 * (distance) * (Mass * obj_moon.Mass) / (sqr(distance)) / Mass) thanks for the help

  • Answers to “What source control system do you use?” (and some winners)

    - by jamiet
    About a month ago I posed a question here on my blog SQL Server devs–what source control system do you use, if any? (answer and maybe win free stuff) in which I asked SQL Server developers to answer the following questions: Are you putting your SQL Server code into a source control system? If so, what source control server software (e.g. TFS, Git, SVN, Mercurial, SourceSafe, Perforce) are you using? What source control client software are you using (e.g. TFS Team Explorer, Tortoise, Red Gate SQL Source Control, Red Gate SQL Connect, Git Bash, etc…)? Why did you make those particular software choices? Any interesting anecdotes to share in regard to your use of source control and SQL Server? I had some really great responses (I highly recommend going and reading them). I promised that the five best, most thought-provoking, responses (as determined by me) would win one of five pairs of licenses for Red Gate SQL Source Control and Red Gate SQL Connect; here are the five that I chose (note that if you responded but did not leave a means of getting in touch then you weren’t considered for one of the prizes – sorry): In general, I don't think the management overhead and licensing cost associated with TFS is worthwhile if all you're doing is using source control. To get value from TFS, at a minimum you need to be using team build, and possibly other stuff as well, such as the sharepoint integration. If that's all you need, then svn with Tortoise would be my first choice. If you want to add build automation later, you can do this with cruisecontrol (is it still called that?), JetBrains, etc. For a long time I thought that Redgate's claims about "bridging the SSMS-VS divide" were a load of hot air, since in my experience anyone who knew what they were doing was using Visual Studio, in particular SSDT and its predecessors. However, on a recent client I was putting in source control for the first time, and I discovered that the "divide" really does exist. That client has ended up using svn with Redgate SQL Source Control, with no build automation, but with scope to add it in the future. Gavin Campbell I think putting the DB under source control is a great idea.  I have issues with the earlier versions of SQL Source Control in that it provides little help in versioning the DB. I think the latest version merges SQL Compare and SQL Source Control together.  Which is how it should have been all along. Sure I have the DB scripts in SVN, but I can't automate DB builds and changes without more tools.  Frankly I'm surprised databases don't have some sort of versioning built into them. Nick Portelli Source control has been immensely useful and saved me from a lot of rework on more than one occasion.  I have learned that you have to be extremely careful checking in data.  Our system is internal only so during the system production run once a week, if there is a problem that I can fix easily(for example, a control table points to a file in the wrong environment), I'll do it directly in production so the run can continue as soon as possible since we have a specified time window.  We do full test runs to minimize this but it has come up once or twice.  We use Red-Gate source control to "push" from the test environment to the production environment.  There have been a couple of occasions where the test environment with the wrong setting was pushed back over the production environment because the change was made only in production.  Gotta keep an eye on that. Alan Dykes Goodness is it manual.  And can be extremely painful at times.  Not only are we running thin, we are constrained on the tools we can get ($$ must mean free).  Certainly no excuse, and a great opportunity to improve my skills by learning new things.  But...  Getting buy in a on a proven process or methodology is hard, takes time, and diverts us from development.  If SQL Source Control is easy to use and proven oh boy could you get some serious fans around here!  Seriously though, as the "accidental dba" of this shop any new ideas / easy to implement tools can make a world of difference in productivity and most importantly accuracy.  Manual = bad. :) John Hennesey (who left his email address) The one thing I would love to know more about is the unique challenges of working with databases as source code - you can store scripts, but are they written as deployment scripts with all the logic about how to apply them to an existing DB? Where is that baseline DB? Where's the data? How does a team share the data and the code? It's a real challenge. Merrill Aldrich Congratulations to the five of you. Red Gate will be in touch with you soon about your free licenses. Thank you to all those that responded. And again, go and check out all the responses – those above are only small proportion from what is a very interesting comment thread. @Jamiet

  • DirectCompute Lectures

    - by Daniel Moth
    Previously I shared resources to get you started with DirectCompute, for taking advantage of GPGPUs in an a way that doesn't tie you to a hardware vendor (e.g. nvidia, amd). I just stumbled upon and had to share a lecture series on channel9 on DirectCompute! Here are direct links to the episodes that are up there now: DirectCompute Expert Roundtable Discussion DirectCompute Lecture Series 101- Introduction to DirectCompute DirectCompute Lecture Series 110- Memory Patterns DirectCompute Lecture Series 120- Basics of DirectCompute Application Development DirectCompute Lecture Series 210- GPU Optimizations and Performance DirectCompute Lecture Series 230- GPU Accelerated Physics DirectCompute Lecture Series 250- Integration with the Graphics Pipeline Having watched these I recommend them all, but if you only want to watch a few, I suggest #2, #3, #4 and #5. Also, you should download the "WMV (High)" so you can see the code clearly and be able to Ctrl+Shift+G for fast playback… TIP: To subscribe to channel9 GPU content, use this RSS feed.

  • Reinstall of Windows Bootloader not working

    - by MrBoxy
    It first started when I deleted my partition that had Ubuntu 12.04 on it. Little did I realize at the time that it would destroy all the resources of Grub on it, and subsequently prevent me booting into my hibernated windows. So I made a 12.10 Ubuntu live USB and reinstalled windows bootloader. When I rebooted it gave me a bootloader error saying I that it could not find the resources to boot from. So I went back to my live USB and installed boot-repair and tried to repair the mbr. It didn't work though. Here is the URL the boot-repair gave me if I was in trouble: paste.ubuntu.com/1328309 Thanks in advance :)
