  • Will having many timers affect my game performance?

    - by iQue
    I'm making a game for android, and earlier today I was trying to add some cool stuff to my game. The problem is this thing needs like 5 timers. I build my timers like this: timer += deltaTime; if(timer >= 2.0f){ doStuff; timer -= 2.0f; } // this timers gets stuff done every 2 secs Will having to many timers like this, getting checked every frame, screw up my games performance? The effect I wanted to add was a crosshair every 2 sec, then remove it after 2 sec and do a timed animation. So an array of crosshairs dependent on a bunch of timers to be exact. This caused my game to shut down when used, so thats why Im wondering if using that many timers causes my game to flip out.

  • Why was Objective-C popularity so sudden on TIOBE index?

    - by l46kok
    I'd like to ask a question that is pretty similar to the one being asked here, but for Objective-C. According to TIOBE rankings, the rise of popularity of Objective-C is unprecedented. This is obviously tied to the popularity of Apple products, but I feel like this might be a hasty conclusion to make since it doesn't really explain the stagnant growth of Java (1. There are way more Android O/S devices distributed worldwide, 2. Java is used in virtually every platform one can imagine) Now I haven't programmed in Objective-C at all, but I'd like to ask if there are any unique features or advantages about the language itself compared to other prevalent languages such as C++, Java, C#, Python etc. What are some other factors that contributed into the rise of Objective-C in this short span of time?

  • How and where do you store your private work/sourcecode?

    - by Amir Rezaei
    I have worked as a developer for over 10 years now. During that time I have had my own small projects where I have developed tools, applications and games. I have not found any robust solution to store my work. It’s always fun to get back to your code and see how you did before and how you would do it now. It’s just work that is unfortunate to lose. There are SVN solution such as Google’s Project Hosting. However I’m not interested in sharing my code or making it open source. Currently I’m hosting my own SVN server. So here comes my question: How and where do you store your private work/sourcecode? Requirements: Sourcecode versioning Backup Prefers free Edit: Remote access Edit: I have used Dropbox + TrueCrypt + SVN. Unfortunately you are limited to 5gb.

  • Any good, easy to learn from books or tutorials for learning assembly? [on hold]

    - by pythonian29033
    I've been a developer since 2009 and I've learnt a lot of languages since, but I've always wanted to understand and be able to code in the lowest level language so I can directly (or at least very close to directly) speak to machines through my code. There was a point in time when someone showed me how to do an if statement in assembly, but out of all the books that I got, I could never really understand where/how to start learning to code in assembler. any help please? I'm obsessed with learning this! PS: if you have any software suggestions, I use ubuntu and am looking to convert to backtrack soon, so it would be preferred if you could give me something that'll be easily installed on debian linux, otherwise don't sweat it, give me the name of the windows software and I'll find an equivalent myself

  • Ubuntu 12.04 GTK Problem

    - by Dana Holt
    I am running Ubuntu 12.04 and compiled and installed GTK 3.4 to go through some GTK developer tutorials. Installing this version of GTK has caused problems with Unity. All system dialogs and top bar now have a different (older) look, and when I try to launch Nautilus I get the following message: Gtk-Message: Failed to load module "canberra-gtk-module" Initializing nautilus-open-terminal extension Initializing nautilus-dropbox 1.4.0 Initializing nautilus-gdu extension nautilus: symbol lookup error: nautilus: undefined symbol: ubuntu_menu_proxy_get I have run make uninstall on the newer version of GTK and reinstalled just about every package I can think of, but I am still having the same problem. How can I repair the default Ubuntu GTK libraries? EDIT Also, I noticed that my desktop icons are gone (launcher works), and I can't interact with the desktop. I can't drag any shortcuts to it, etc.

  • How to Save Hundreds or Thousands of Dollars on Cell Phone Service

    - by Chris Hoffman
    Cell phone contracts are bad. You get a seemingly cheap phone up front, but you more than pay for the cost of the phone over two years. Prepaid phone plans are surging in North America for a reason. Prepaid phone plans will be cheaper and more flexible than traditional contracts with big carriers for many people. However much you use your phone, there’s a good chance you can save money with a prepaid service. No More Contracts Here’s how cell phone service typically works in North America: You get a subsidized phone for “free”, $99, or $199. You sign up for a two-year contract and more than pay back the cost of that phone over the length of the contract. This is similar to leasing something or purchasing it on a credit card and paying it back over two years — you spend less up front, but you’re paying more in the long run. But this isn’t the only option. You could opt for a cheaper prepaid service that doesn’t lock you into a contract. If you don’t use your phone much, you could just pay for what you use and avoid the hefty cell phone bills. If you use your phone a lot, you could get a cheaper plan, too. Now, this certainly isn’t for everyone. If you want the latest iPhone or Galaxy smartphone every two years and require a 4G data connection, prepaid services may not be for you. On the other hand, if you don’t need the latest phone, you can save money here. You can also save a huge amount of money if you don’t use your phone much. Phone Options When you choose your prepaid or contract-free service, you’ll often be able to purchase a phone from them. You’ll generally be able to find dirt-cheap dumbphones and the cheapest, slowest Android phones for not very much money. If you are able to buy a top-of-the-line smartphone, you’ll have to pay the full, unsubsidized price. That’s $649 for either an iPhone 5S or Samsung Galaxy S4. Whatever phones the service provider offers, you could always buy a phone elsewhere — for example, you could buy an unsubsidized iPhone direct from Apple and then take it to your cell phone service of choice. Most services will allow you to get a SIM card and pop it into your existing phone rather than purchasing a phone. If you can get a hand-me-down smartphone, you can often save quite a bit of money. For example, you may have a family member upgrading from an iPhone 4S to an iPhone 5S. You could take their phone to a prepaid carrier and have a nicer phone on a cheap cell phone plan. If you brought an old smartphone to a big carrier like AT&T or Verizon, they wouldn’t give you a discount on your monthly plan. You’d have to pay the same amount of money every month as if you had gotten a subsidized phone. Google’s Nexus phones are also great options for people looking to buy smartphones and pay up-front. Google’s Nexus 4 offered a modern, almost top-of-the-line Android smartphone experience at $299 or $349 when it came out last year. Google will soon be releasing the Nexus 5 and it’s expected to be priced at $349. That’s certainly a lot more than a cheap phone, but it’s a fairly high-end smartphone at almost half the price of an iPhone 5S or Galaxy S4. Nexus phones can be purchased online from Google’s Play Store. Service Options When choosing a service, you need to consider what you actually use. If you’re someone who only uses your phone rarely, you can get plans that will allow you to pay as little as a few dollars per month. If you’re someone who’s usually in range of Wi-Fi, you may not need much data at all. If you want a plan with unlimited talk, texting, and data usage, you can get it for much cheaper than you’d pay on a major carrier like AT&T. The options here range from pay-as-you-go plans, like the ones offered by T-Mobile, which allow you to put a certain amount of money in and only drain that balance when you actually use minutes, texts, or data. If you only make a few calls and send a few texts per month, you’d only pay a few bucks. On the other end, Walmart’s Straight Talk service is a popular option that offers unlimited talk, texting, and data at $45 per month. Which service is right for you depends on a lot of things, including your usage and what each network’s coverage is like in your area. You’ll want to do some research of your own before choosing a service. Prepaid services also offer you even more flexibility after you choose one. If you’re not happy or a better deal comes along, you can switch — you’re not locked into your service for two years and you won’t pay an early termination fee.

  • Environment naming standards in software development?

    - by Marcus_33
    My project is currently suffering from environment naming issues. Different people have different assumptions as to what environments should be named or what the names designate, and it's causing confusion when discussing them. I've done a bit of research and I haven't found any standards out there. The terms include "Local", "Sand", "Dev", "Test", "User", "QA", "Staging" and "Prod" (plus a few more that different people have asked about) I'm not looking for just opinions, though if there's one out there that "everyone" has I'll take it - I'm trying to find definitions advanced by some sort of authority, even if it's unofficial. Here's the environments we currently use: Environment on the developer's PC Shared Environment where developers directly upload code to self-test Shared Environment where standards and functionality are tested by QA people Shared Environment where completed and QA-checked code is approved by project requesters Environment that mirrors the final environment as a final check and to prepare for deployment Final Environment where code is in use I know what I'd call them, but is there some sort of standard on this? Thanks in advance.

  • Wanted, Joel Spolsky Clone... slighty used acceptable

    - by SetiSeeker
    Hi All, First of all I have been playing with where to post my question(stackoverflow, meta.stackoverflow or here). So if this is the wrong place, my apologies to all. I love Joel Spolsky's website, Joel on Software. I love the way it mixes developer knowledge, with business knowledge and various other bits of info about, creating, building and surviving dev projects and products. So now for my question, are there any other sites, blogs or people that are similar in content and nature to Joel Spolsky and his site? Thanks.

  • what is the simplest 3d software for unity?

    - by kdavis8
    Ive heard a lot about Daz studio, Poser, Maya, K-3d, Anim8or, Blender, and all the rest. My question is which one is the best choice in terms of simplicity and quality. price is not an issue really. I'm programming games in java for android mobile devices at the moment but i will eventually move onto larger platforms. I would like to utilize unity3d for the game programming itself and utilize a 3d modeling software just to create the game objects. I just need to know the best one to get started with from scratch or should i use a combination of multiple ones? Any insight for this would be great, thanks!

  • Windows Phone 7 Development &ndash; Useful Links

    - by David Turner
    Here are some excellent links for anyone developing for Windows Phone 7: J.D. Meier’s Windows Phone Developer Guidance Map – this is immense.  Also check out the Silverlight version Justin Angel’s site – some really great articles on unlocked roms, automation and Continuous Integration Windows Phone 7 Development Best Practices Wiki Jeff Blankenburg’s 31 days of Windows Phone 7 This post of Links to sample code for Windows Phone Tim Heuers blog, particularly this post of Tips and Tricks Kevin Marshall's blog, particularly the epic WP7 Development Tips Part 1 post Code Samples for Windows Phone on MSDN If you have unlocked your phone for development, then you can use the WPConnect tool to connect to the device rather than using the Zune client.  I found it useful to pin a shortcut to WPConnect in my Start Menu. The Performance Counters displayed when you debug your app on a device are useful for seeing things like frame rate and memory usage, this page on MSDN explains what the numbers mean.  Jeff Blankenburg covers this in more details on his blog I also came across this set of links to tutorials recently which looks very useful.

  • Is it true that first versions of C compilers ran for dozens of minutes and required swapping floppy disks between stages?

    - by sharptooth
    Inspired by this question. I heard that some very very early versions of C compilers for personal computers (I guess it's around 1980) resided on two or three floppy disks and so in order to compile a program one had to first insert the disk with "first pass", run the "first pass", then change to the disk with "second pass", run that, then do the same for the "third pass". Each pass ran for dozens of minutes so the developer lost lots of time in case of even a typo. How realistic is that claim? What were actual figures and details?

  • 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?

  • Best SEO practices for mobile URLs: 301, rel=canonical, or something else?

    - by Chris
    I am developing a site with a mobile version and am trying to figure the appropriate way to manage the URLs for search engines. So far I've considered: Having a separate mobile site (m.example.com) with rel="canonical" links to the regular site. Putting both the mobile site and full site on one URL (example.com), and doing user agent sniffing. Another opinion: Spencer: "If you have a mobile site at a separate location or URL, you should 301 redirect each and every mobile page to its corresponding page on your main website. Employ user agent detection so that the mobile optimized version is served up if someone's coming in from a hand-held. - http://developer.practicalecommerce.com/articles/1722-Mobile-site-Development-Best-Practices-for-SEO-Usability Both 2 and 3 make it hard for a user who wants to switch to the full site or mobile site manually, but I'm not sure 1 is the best alternative. What's the best way to write URLs for a mobile site?

  • Set up development site on another server/host

    - by Ofeargall
    I'm developing a site for a client. They've got a site now that's hosted at hosting.com. I'm going to move them to my VM hosting solution at edge web but I want to run some tests and have the client approve the site before changing the name servers to the new site/hosting location. How do I make this happen? I'm running a red hat/Apache on linux for the edge web hosting. I don't have control of the domain name (i.e. the client controls that right now). Edgeweb has set up a dns zone for the domain name so that when the time comes to switch we're ready to go. I'm a web developer and I understand the technologies that make a user experience 'work' but I'm unfamiliar with the server jargon and all that so, please be patient. Thanks in advance.

  • Project planning and customer tracking system

    - by Daniel Hollands
    First off, sorry if this is the wrong 'stack' site, but it seemed like a good place to start. I'm happy to report that my services as a web developer are starting to be in quite a lot of demand, and I have a few existing and potentially new customers all lining up - but I'm finding it very hard to keep track of everything. What I'm hoping for is some (preferably web-based) system which I can use to keep track of who my customers are, the various projects that I've got going on for them, and (if possible) the individual sub-tasks that make up each project. What would be even better is if the relevant customer was able to log into the site, and see the process of their projects. I do hope you know what I'm talking about, and that you'll be able to offer some suggestions of either web-base sites that offer something along these lines, or of some open source solution or something like that? Thank you

  • AWS EC2 Oracle RDB connection to Oracle Database Instance

    Provisioning my Oracle database instance to AWS EC2 RDB was easy. Just a few clicks! However, getting my connection to my Oracle cloud database was not as easy. A couple things that are not obvious (using Oracle SQL Developer): 1. Need to set up a database security group. 2. Need to use end point for the host name. This video is the best one on the internet to explain both points: http://www.youtube.com/watch?v=ocFURuX0eEw

  • Tell Visual Studio 2012 UI Designers What to Fix

    - by Ken Cox [MVP]
    If you hate the default interface themes in Visual Studio 2012 as much as I do, you have another outlet to vent. The UI designers have posted a survey where you can tell them how distracting and annoying you find the gray themes and black icons. You even get to comment on the (fixable) all-caps issue. The UI people didn’t listen much to the (largely hostile) developer feedback during the product design – or more likely were constrained by some edict from on high - but seem more willing now to create decent themes for updates. Here’s the Visual Studio 2012 Visual Theme survey URL https://illumeweb.smdisp.net/collector/Survey.ashx?Name=VS2012ThemeSurvey VS 2012 is a great product hampered by a lousy UI. If I could have a Visual Studio 2010 theme (with its coloured icons) I’d be more than satisfied with the 2012 release.

  • .NET - refactoring code

    - by w0051977
    I have inherited and now further develop a large application consisting of an ASP.NET application, VB6 and VB.NET application. The software was poorly written. I am trying to refactor the code as I go along. The changes I am making are not live (they are contained in a folder on my development machine). This is proving to be time consuming and I am doing this along side other work which is the prioritiy. My question is: is this a practical approach or is there a better methodology for refactoring code? I don't have any experience with version control software or source control software and I am wandering if this is what I am missing. I am a sole developer.

  • Checking for cross-site scripting vulnerabilities in Perl web applications

    - by David Scholefield
    I'm putting together some notes for a dev team on how to write secure Perl code - especially taking into account the current OWASP top 10 web application vulnerabilities. For cross-site scripting I've included information on ensuring that all output to the browser is checked and escaped where necessary, but I'm looking for more automated mechanisms that would mean a developer doesn't have to think about every output statement and, potentially, miss one. Perl's 'taint' function sounds like it should be a help because it distrusts all user input, but it doesn't complain on tainted data being output to the browser. Apart from checking all output statements individually (probably by calling a generic sanitizing function) does anyone have any ideas on how Perl can help with this with existing libraries or techniques?

  • Cross platform mobile development VS Native Mobile Development: Present And Future.

    - by MobileDev123
    I just completed one year in Smart phone development, working on BlackBerry and Android and also developed one application exclusively targeted to nokia feature phones. And just a month ago I come to know about Titanium Appcelerator tool that enables cross platform development, but there are some developers who complain about it's sub-par functionalities. Even a little bit experience of mine says that developing in native environment rather than these cross platform tools will give you more advantages by giving a developer a chance to add more features with better performance. Do you have same experience? Or you find such cross development tools really useful regarding to advance functionality and performance? As porting (or co developing) same application to different mobile platform is common thing nowadays, what do you think will these cross platform tools evolve and force developers to get a hands on approach on them or majority will stick to the native development environment?
