• A good example project to 'prove' my skills [closed]

  - by David Archer

  I've been a commercial programmer for about 3 years now but all of my commercial work is based upon PHP (with Cake PHP, Wordpress and Wildfire) and ASP.Net (on C#, including MVC 3, Umbraco and Kentico) as well as plenty of HTML/CSS/jQuery examples to show. A future employer has asked me to show my Ruby on Rails potential. I've done Ruby on Rails before for fun, but nothing worthy of commercial showing. What I'd like to know, from a group of programmers, is what would be a good 'portfolio demo' piece for you? What have you seen in the past that impressed you? What are you looking for? For Ruby lead developers specifically, what sort of things are you looking to see in the code? Cheers!

• 3D Studio Max biped restrictions?

  - by meds

  I have a stock biped character in 3D studio max which has a jump animation. The problem I have with the jump animation is that there is actual y offset happening inside it which makes it awkward to play while the character is jumping since it's not only jumping in the game world but the jump animation is adding its own height offset. I'm tryuing to remove the jump animations height offset, so far I've found the root node and deleted all its key frames which has helped a bit. The problem I'm having now is that the character still has some height offset and if I try to lower it it has a fake 'ground' that isn't at 0 and the limbs sort of bend on the imaginary floor, si there a way to remove this restriction just for the jump animation? Here's what I mean: http://i.imgur.com/qoWIR.png Any idea for a fix? I'm using Unity 3D if that opens any other possibilities...

• Collaboration between client, web designer, and web developer

  - by Alex

  I am primarily a Web Developer (back end programming) - but intend to offer a complete service to my clients, from concept, to brand design, photoshop mock-ups and everything else in between. I'm aware that it's a good idea to outsource this design aspect of the project to someone that I trust. My question is more about the process: I imagine that in order for the designer to really grasp what the client wants to create, they would need some sort of interaction. Therefore, does anyone know if it is common to bring both parties into a 3 way discussion? Or is it more common to get all of the info from the client, and then pass it onto the designer, and act as a back and forth middleman? Afterall, I am the designer's client. Any insight into this would be great

• Are there any formalized/mathematical theories of software testing?

  - by Erik Allik

  Googling "software testing theory" only seems to give theories in the soft sense of the word; I have not been able to find anything that would classify as a theory in the mathematical, information theoretical or some other scientific field's sense. What I'm looking for is something that formalizes what testing is, the notions used, what a test case is, the feasibility of testing something, the practicality of testing something, the extent to which something should be tested, formal definition/explanation of code coverage, etc. UPDATE: Also, I'm not sure, intuitively, about the connection between formal verification and what I asked, but there's clearly some sort of connection.

• Favorite Visual Studio 2010 Extensions

  - by Scott Dorman

  Now that Visual Studio 2010 has been released, there are a lot of extensions being written. In fact, as of today (May 1, 2010 at 15:40 UTC) there are 809 results for Visual Studio 2010 in the Visual Studio Gallery. If you filter this list to show just the free items, there are still 251 extensions available. Given that number (and it is currently increasing weekly) it can be difficult to find extensions that are useful.

• Loads wrong resolution when installing

  - by Kevin DB

  I'm trying to install Ubuntu 11.04 from a USB. My computer does load the USB file and I get some sort of BIOS-like screen where I can choose between 'Install from USB' and 'Boot-up from USB'. When I entered the corresponding number my screen resolution is totally messed up. I see that Ubuntu is starting up when I used Boot from USB, but the screen looks the same as you'd have a too high screen resolution. Same story with Install from USB. I can see the screens loading and the menu's and stuff, but not clearly because it load in a too high screen resolution. I'm trying to dual-boot is with Windows XP and max. screen resolution is 800x600.

• Ubuntu touch flashing failed/taking to long. Black screen! Redeploy help!

  - by Marius Rye

  So i'm brand new to the whole unlock, root and flashing thing. I just tried flashing Ubuntu touch on my Galaxy Nexus (international GSM/HSPA+) and everything seamed fine until the very end when i got this ERROR message. ERROR:phablet-flash:Installation is taking too long or an error occured along the way. I didn't know what to do so i disconnected my device (which was in Ubuntu recovery) and tried rebooting it from there, it worked "sort of". i got the Google logo with the unlocked icon then it continued to a black screen. In the installation guide on http://www.ubuntu.com/phone/install said i should: "try wiping the /data partition on your device and redeploy". the problem is that i don't know how to do this and i'm basically sitting here with a useless phone right now. I would be extremely grateful for some proffeexpert help.

• Could the rel="author" just be a username?

  - by Gkhan14

  I want to use rel="author", however the type of blog I run is about a game, and doesn't relate to my real identity. I'm more known for my screen name, so would this still be okay to use for the rel="author" tag? For example, if my Google+ account is for my user, and not for myself, could I still use it within the rel="author" tag? I don't want to get penalized in any sort of way. My main reason to do this, is to improve click through rate, and just make my blog post sections look better in the searches.

• Web-based CMS for mobile app

  - by JWood

  I'm just about to start developing a mobile app which needs to be fed from a CMS. I started designing the tables when I thought there must be something out there which could save me a load of time and let me concentrate on the mobile side of things. So, I'm looking for a CMS that will let me create hierarchical "pages" which will just be 4-5 database fields with a simple front-end to allow to edit and update them. I don't mind having to write some code to layout the database and forms etc, any saving on starting from scratch would be good. The only requirement is that I be able to access the data via some sort of web service, REST, JSON, XML, anything really... Can anyone suggest anything that might help? Thanks, J

• Why does my display keep turning off every 10 minutes?

  - by George Edison

  I have installed Ubuntu 11.10 (Oneiric) in VirtualBox as well as virtualbox-guest-additions . The display resolution adapts to the size of the window as expected, but the display turns off after 10 minutes of inactivity. Thinking there was some sort of power management issue at play, I went to Power in the settings dialog: There doesn't really seem to be anything there that mentions "turn off display after xxx minutes" so I assume everything is configured correctly there. Next I went to Screen and found an option there "Turn off after:". Aha! I thought. Now I have found the option - but alas: even after setting it to "never" and restarting multiple times, the display still shuts off after 10 minutes. What am I missing? What option am I overlooking?

• Using YouTube as a CDN

  - by Syed

  Why isn't YouTube used as a CDN for video and audio files? Through YouTube's api and developer tools, it would be possible to post all media files to YouTube from a CMS and then make a call to them when needed. This seems like it's within YouTube's TOS, it's a cost-effective way to store, retrieve, and distribute media files, and it could also make for easy monetization. I ask because I'm working on a new project for a public radio station. I can't figure out the real downside to this sort of an implementation.

• Securely expose WebService from Enterprise Network to Internet Client

  - by hotzen

  Are there any standards (or certified solutions) to expose a (Web-)Service to the internet from a very security-sensitive network (e.g. Banking/Finance)? I am not specifically talking about WS-* or any other transport-layer security á la SSL/TLS, rather about important standards or certifications that must be obeyed. Are there any known products (coming from an SAP-environment) that can provide a "high-security proxy" of some sort to expose specific web-services to the internet? Any buzzwords that a CIO/CTO is aware of about this subject?

• Visitors have old website cached in their browsers

  - by RussianBlue

  My client's new website is example.com, the old website is example.co.uk. I've re-pointed the A Records to the new website (so as to leave the emails alone) and put in 301 redirects from old pages to new pages. But, my client is upset as he (and he thinks many of his clients) have the old website cached in their browsers and won't know how to clear their browser cache. Is there anything I can do to overcome this and if not, what sort of time will browsers finally stop using their cached pages so I can at least go back to my client and tell him that his clients will finally start to see the new website?

• is gnome 3 is slow or my machine?

  - by user103054

  I have Dell XPS 15 i7 - 2360 with nvidia 525M (1GB) with optimus running Ubuntu 12.10 64 bit and have bumblebee installed for optimus. Recently I installed Gnome Shell to give it a try and found it sort of lagging under few scenarios though rest all is butter smooth. When I click on Date gnome 3 it appears as if a second has elapsed before the window is drawn. But others panel items like network or volume looks fine. In gnome 3 when I'm on dash with (window preview) if I remove any of the windows before the remaining windows reshuffle it takes about 2 seconds (noticeable clearly). Everything else is fine in both unity and Gnome Shell. What is causing this slowness? Is Gnome Shell is really slower?

• handling a GET error properly

  - by Andrew Heath

  I have a website that takes two primary get strings: ?type=GAME&id=SomeGameID ?type=SCENARIO&id=SomeScenarioID for reasons unknown, I have recently begun receiving requests for erroneous get strings from both Yandex and Baidu. They are always in the form of: ?type=GAME&id=SomeScenarioID None of my users are triggering these errors, so I am (sort of) confident that this is not due to an HTML template error somewhere on my part. There is also no HTTP_REFER showing up in the $_SERVER array, so I'm guessing these are direct requests from bad dbase data on their part. I see two options for dealing with these bad requests, and would like to know which is recommended... or if there are other, better options I have not thought of: simply 404 the request, since it is incorrect redirect the request to ?type=SCENARIO&id=SomeScenarioID because the scenario IDs are always valid, the breakage is due to asking for the wrong type.

• How can test users access an unpublished iOS app?

  - by David

  I am considering outsourcing the development of an iOS app to various independent developers. I will have have various testers of the app. We all work for separate companies. Some of these testers will be customers, who I would like feedback from. As there are multiple developers involved I expect there to be a new release on a daily basis. How can this be done? Would each of the testers need to buy some sort of license to avoid having to go through the app approval process? Is there any smooth way to do this so that it will not be a hassle for our friendly customers, who are willing to test our app?

• Push or Pull Input Data In the Game Logic?

  - by Qua

  In the process of preparing my game for networking I'm adding a layer of seperation between the physical input (mouse/keyboard) and the actual game "engine"/logic. All input that has any relation to the game logic is wrapped inside action objects such as BuildBuildingAction. I was thinking of having an action processing layer that would determine what to do with the input. This layer could then be set up to either just pass the actions locally to the game engine or send it via sockets to the network server depending on whether the game was single- or multiplayer. In network games it would make sense that the player's actions should be sent to the server, but should the game logic be pulling (polling?) the data through some sort of interface or should the action processing layer be adding the actions to an input queue in the game logic code?

• How do I generate terrain like that of Scorched Earth?

  - by alex

  Hi, I'm a web developer and I am keen to start writing my own games. For familiarity, I've chosen JavaScript and canvas element for now. I want to generate some terrain like that in Scorched Earth. My first attempt made me realise I couldn't just randomise the y value; there had to be some sanity in the peaks and troughs. I have Googled around a bit, but either I can't find something simple enough for me or I am using the wrong keywords. Can you please show me what sort of algorithm I would use to generate something in the example, keeping in mind that I am completely new to games programming (since making Breakout in 2003 with Visual Basic anyway)?

• How do I determine the draw order in an isometric view flash game?

  - by Gajet

  This is for a flash game, with isometric view. I need to know how to sort object so that there is no need for z-buffer checking when drawing. This might seem easy but there is another restriction, a scene can have 10,000+ objects so the algorithm needs to be run in less than O(n^2). All objects are rectangular boxes, and there are 3-4 objects moving in the scene. What's the best way to do this? UPDATE in each tile there is only object (I mean objects can stack on top of each other). and we access to both map of Objects and Objects have their own position.

• Embed IF text parser in another game?

  - by DragonFax

  Are there any existing interactive fiction text parsing engines that I can embed in another game or application? I'm looking to use something as a library. I can pass it the available objects and verbs from my own side. It will parse the sentences from the user and give me back some sort of structure/AST describing what the user asked for. Then my own code can then act upon that request. I don't need something SIRI level. The simple sentences and actions that current IF games support is fine. But I'm not looking to write a whole text/sentence parser myself. This isn't an If game and I can't write it entirely in an interactive-fiction language like inform 7. Unfortunatly, I can't seem to find any examples of anyone using the text parsing capabilities of these engines without writing the entire game in that engine's language.

• What You Said: How You Monitor Your Computer

  - by Jason Fitzpatrick

  Earlier this week we asked you to share your computer monitoring tips and tricks, now we’re back to share the wealth. Read on to see how your fellow reader monitor their gear. One of the more popular monitoring tools, thanks in part to the amount of things beyond just hardware it can monitor, in the comments was Rainmeter. Lee writes: I don’t really monitor my computer constantly, only when something is hanging up and I need to see what’s causing it. That being said, I do have Rainmeter so I can quickly see how much RAM or CPU is being used. For anything more detailed, I just go into the task manager and sort by RAM or CPU.

  Firefox souffle sur sa dixième bougie que pensez-vous de l'évolution du navigateur de Mozilla Firefox souffle sur sa dixième bougie cette semaine. 10 ans déjà que le navigateur de la fondation Mozilla participe à l'évolution du Web. C'est l'occasion pour faire une petite rétrospective de son évolution. 23 septembre 2002, la version 0.1 de Phoenix sort. Le navigateur basique dont le développement a commencé le 31 mars 1998 par des développeurs de Nestcape est considéré comme la première version de Firefox.
