  • Updates for IOS AppStore Multiplayer Game

    - by TobiHeidi
    I am developing a multiplayer game for the web, android and ios. For the web and android i can instantly push out new versions of my game because they support executing remotly loaded code. But with IOS i need to wait for an Apple approval taking about 10 days. I want to push updates more then weekly. What if my server code changes so the client MUST update? Run an old version of the server code just for IOS? How do other multiplayer devs handle this ?

  • Share on Facebook does not show thumbnail images

    - by matt74tm
    I have a PHP application which has a "Share on Facebook" button that, On the development server shows the thumbnail images correctly and allows the user to select between them On the live server, it does NOT show the thumbnail images at all. The relevant portion of the .htaccess file is: # Set up caching on media files for 2 days <FilesMatch "\.(gif|jpg|jpeg|png|flv)$"> ExpiresDefault A172800 Header append Cache-Control "public" </FilesMatch> I'm using the exact same set of php files and .htaccess, but the server configuration is different. What could be causing this? Note that the text appears fine. Edit1 We are also doing some URL rewriting related to images in the .htaccess (on both servers): ... RewriteRule ^.*/content/image/(.*)$ content/image/$1 [L] ... RewriteRule ^.*/images/(.*)$ images/$1 [L] ... Would that be somehow making a difference? Images appear fine all throughout the site. (I posted this question earlier as http://stackoverflow.com/questions/4142597/share-on-facebook-does-not-show-thumbnail-images) )

  • How do you choose a programming/data structure/algorithm book?

    - by Fanatic23
    I really should not be mentioning the name of the book, but the first time I read it (during my under-grad days) I almost concluded that data structure was a bad course to pick. Which brings me to the question I am asking here. What makes a programming or data structure or algorithm book tick? Clearly, lucid explanation is one. But I also realize that organization of the material is very important and so is diagrams. What else? Some pointers would obviously help when I hang out in my neighborhood computer book shop the next time.

  • How far back do you use your version control and for what reason?

    - by acidzombie24
    Typically when i work on a project i only go back a few days or the last major change when i decide to do something drastic. I sometimes notice i broke a test or a feature and overlooked it for a few weeks so i may go back a month or two and see if the feature or test is broken and trace down the week i broke it. Then find what change did it. On a long term project over the span of a year. Do you actually go back 6+ months and if so why?

  • No sound, even though devices appear OK

    - by Felix
    I have a weird problem. Sound used to work until a couple of days ago, but now the builtin speakers in my ThinkPad W520 have stopped working. This happened after either: An update Using the headphone jack in my laptop dock (I had used the jack in the actual laptop before without issues) As I was saying, the speakers do not work at all. Sometimes I get a clicking sound from the laptop, which I assume is the system beep. This does not happen consistently. If I plug headphones in the laptop, I do get sound in them. I have tried playing with all the possible settings both in gnome and using alsamixer. Some screens: What could I try next?

  • Update live USB distro?

    - by qubex
    I have Lubuntu 14.04 (and Ubuntu 14.04) on a pair of USB disks created by writing the img files to USB using dd on Mac OS X. Unfortunately these systems both have some known bugs (that have since been corrected) and lack certain important drivers for my system (which I have located online). How can I make the USB disks writable and how do I update the distribution upon them as one may do for a locally-installed system? And if I later proceed to install from these USB sticks onto a hard-drive, will they ‘carry’ the package and driver updates with them or will I have to start from scratch again? (I seem to remember from my ancient Windows XP days that such procedures were referred to as ’slipstreaming’ or somesuch on that side of the fence.) (No, I did not create a persistence partition when I created the sticks, because from Mac clearly that isn’t an option. And anyway, as I imperfectly understand it, the persistence partition is for user files and not for the modification of the system.)

  • Why Wikipedia doesn't appear as a referral in Google Analytics' Traffic sources?

    - by Rober
    One of my clients has a website and got not spammy backlinks in a Wikipedia article. When I test it for SEO purposes with Google Analytics (from different IPs), apparently there is no referral information. On the Real-Time view my test visit is visible but with There is no data for this view in the referrals subview. And this visits appear as (direct) / (none) on the Traffic sources view. Wikipedia is not hiding in any way its links origin, since it is shown in the server visits log. Is Google ignoring Wikipedia as a referral? Am I missing anything else? Update: Now it works, several days after the link was active. Maybe something is detecting for how long the link was there so that it doesn't work just from the beggining, as a security measure? Many visits are actually not recorded.

  • How do I clear all gnome shell notifications?

    - by user19448
    I use Jupiter as a power manager. Now I get a good number of notifications from it. I do not have problem with the fact that I get all these notifications. I do however, want to be able to clear all gnome shell notifications with a few clicks. Currently, my entire bottom edge of the screen is filled with notifications and I do not wish to clear each item one by one. So my question is, how do I clear these notifications? If this is not possible in the ui, is it possible to write an extension to do it? Where should I suggest this feature to gnome developers? Gnome forums are almost dead now, the administrator has not activated my created account since 5 days!

  • aticonfig detects all graphics cards, but amdcccle shows the cards as disabled

    - by DevZer0
    I been having the strangest problem since few days ago. I have 3 ATI graphics cards and the aticonfig --list-adapter shows the following output * 0. 01:00.0 AMD Radeon HD 7900 Series 1. 02:00.0 AMD Radeon HD 7900 Series 2. 05:00.0 AMD Radeon HD 7900 Series when i do aticonfig --adapter=all --initial -f it generates the correct X config also. but after rebooting the output only show on primary monitor and when i look in amdcccle it shows the other 2 adapters as disabled. I tried with monitors attached and dummy plugs both but the situation doesn't change. Any idea whats causing this? also right clicking and making the adapter enabled in amdcccle and saving changes causes the X config to only have the adapter section and no screen section. after reboot the situation stays the same.

  • Administrator user session only shows a terminal

    - by Saariko
    Weird problem: After upgrading to 11.10 (and I am sure that I worked with it for couple of days). We had a power failure, and now, when open the computer, what I get is a screen, with a scrollable list of users (administrator is one of them). When I select the administrator user, and login, I get on the top left a terminal window. That's it ! I don't see my regular ubuntu desktop. What's wrong? I have tried some of the issues mentioned here: Delete the .Xauthority sudo apt-get update *I had some DNS errors, so had to fic my /etc/resolv.config (works now) please advise.

  • How do you encourage yourself to program?

    - by Goma
    Imagine that you were given a studio or a room in 7-star hotel which is located by the sea, a luxury car and free massage service. All that were given on the condition that you should write your best code every day. You should come with new ideas and try and try again and again.. Will you accept that? Now come back to me please, the question is: what do you do to encourage youself to like programming and to write more of best practices and to come with new ideas? For example, if you were writing code and you get bored, in this case what do you do? Another example is, what do you do when some days are passed and you did not write anything? How do you recover and get back to work with high energy?

  • Which other "photo booth" program can I use besides cheese (on a Toshiba AC100)?

    - by imz
    After installing Ubuntu 12.04 on a Toshiba AC100 several days ago, as described at https://wiki.ubuntu.com/ARM/TEGRA/AC100, and seeing during the installation that the OS was able to use the camera (the installer suggested to make a photo for the first user), I wanted to play with the camera. I couldn't understand how to find a "photo booth" program in the new-style menu+desktop (not the classical menu with sections), so I remembered the popular "cheese" Linux program, and installed it via the Software Update tool (or whatever it is called; can be invoked from the panel on the desktop). But cheese doesn't start, i.e., it crashes. (The bug report telling the same.) As I said, the camera could be used by the OS on this machine -- this could be seen in the installer. Which "photo booth" programs can be installed and used without crashes in Ubuntu 12.04 on a Toshiba AC100 in order to play with the webcamera?

  • Some Early Considerations

    - by Chris Massey
    Following on from my previous post, I want to say "thank you" to everyone who has got in touch and got involved – you are pioneers! An update on where we are right now: paper prototypes v1 To be more specific, we’ve picked two of the ideas that seem to have more pros than cons, turned them into Balsamiq mockups, and are getting them fleshed out with realistic content. We’ll initially make these available to the aforementioned pioneers (thank you again), roll in the feedback, and then open up to get more data on what works and what doesn’t. If you’ve got any questions about this (or what we’re working on right now), feel free to ask me in the comments below. I’ve had a few people express an interest in the process we’re going through, and I’m more than happy to share details more frequently as we go along – not least because you, dear reader, will help us stay on target and create something Good. To start with, here’s a quick flashback to bring you all up to speed. A Brief Retrospective As you may already know, we’re creating a new publishing asset specifically focused on providing great content for web developers. We don’t yet know exactly what this thing will look like, or exactly how it will work, but we know we want to create something that is useful different. For my part, I’m seriously excited at the prospect of building a genuinely digital publishing system (as opposed to what most publishing is these days, which is print-style publishing which just happens to be on the web). The main challenge at this point is working out our build-measure-assess loop to speed up our experimental turn-around, and that’ll get better as we run more trials. Of course, there are a few things we’ve been pondering at this early conceptual stage: Do we publishing about heterogeneous technology stacks from day 1, or do we start with ASP.NET (which we’re familiar with) & branch out later? There are challenges with either approach. What publishing "modes" are already being well-handled? For example, the likes of Pluralsight, TekPub, and Treehouse have pretty much nailed video training (debate about price, if you like), and unless we think we can do it faster / better / cheaper (unlikely, for the record), we should leave them to it. Where should we base whatever we create? Should we create a completely new asset under a new name, graft something onto Simple-Talk (like the labs), or just build something directly into Simple-Talk? It sounds trivial, but it does have at least some impact on infrastructure and what how we manage the different types of content we (will) have. Are there any obvious problems or niches that we think could address really well, or should we just throw ideas out and see what readers respond to? What kind of users do we want to provide for? This actually deserves a little bit of unpacking… Why are you here? We currently divide readers into (broadly) the categories: Category 1: I know nothing about X, and I’d like to learn about it. Category 2: I know something about X, but I’d like to learn how to do something specific with it. Category 3: Ah man, I have a problem with X, and I need to fix it now. Now that I think about it, I might also include a 4th class of reader: Category 4: I’m looking for something interesting to engage my brain. These are clearly task-based categorizations, and depending on which task you’re performing when you arrive here, you’re going to need different types of content, or will have specific discovery needs. One of the questions that’s at the back of my mind whenever I consider a new idea is “How many of the categories will this satisfy?” As an example, typical video training is very well suited to categories 1, 2, and 4. StackOverflow is very well suited to category 3, and serves as a sign-posting system to the rest. Clearly it’s not necessary to satisfy every category need to be useful and popular, but being aware of what behavior readers might be exhibiting when they arrive will help us tune our ideas appropriately. < / Flashback > We don’t have clean answers to most of these considerations – they’re things we’re aware of, and each idea we look at is going to be best suited to a different mix of the options I’ve described. Our first experimental loop will be coming full circle in the next few days, so we should start to see how the different possibilities vary between ideas. Free to chime in with questions and suggestions about anything I’ve just brain-dumped, or at any stage as we go along. If you see anything that intrigued or enrages you, or just have an idea you’d like to share, I’d love to hear from you.

  • Switching my legacy desktop back to Windows XP from Windows 7

    - by Kevin Shyr
    I was happy with Windows 7 at the beginning, until I started to add in the peripherals.  Windows 7 was never able to recognize any of my PCI video card (I know, I know, we should be in the DVI age). Anyway, I went through another 4 days of trouble setting my computer up with dual monitor in XP (also did a bunch of other things like getting rid of my sound card and taking the computer off RAID. Kind of feel stupid to put the computer on RAID in the first place because now I can have 2 drives: double the page files program seems to run faster Microsoft Sync toy 2.1 takes care of my backup needs (Thank god they solved the network drive issue) As of last night, the system is running beautifully.  I still have a laptop with Windows 7, but even that is in dual boot mode.

  • Is there anywhere where I can get Ubuntu installed for me?

    - by user3911336
    I have tried for days to install Ubuntu on my lenovo ideapad z510 and I feel like giving up. I really feel like I will like Ubuntu, but for some reason I always have some king of problem. I really don't want to give up on Ubuntu, but I don't want to brick my laptop either. Is there anywhere I can have Ubuntu installed for me? I have tried messing with my bios, used a DVD and a USB, but no luck. Thanks in advance! Edit: I am based in Warwick, RI in the USA. I don't want to run Ubuntu in windows.

  • Is there any way to get faster app reviews?

    - by David
    I am trying to build a business around an iPhone app. The app will be our main sales channel, and being able to adapt the sales channel faster than the 9-10 days delay cause by the app review times is crucial. Therefore, I was wondering whether there is anything I can do to improve the speed of reviews. I am thinking that the publishers of Angry Birds, surely would not have to wait in line for reviews on the same terms as some obscure free app. So what can I do? Some things I am considering: Would Apple prioritize apps that they earn money on? Could I in some way pay Apple directly? I already know of the possibility of requesting an expedite review, but it seems like one can get punished for supplying a non-technical reason.

  • GeForce8800 ultra

I have a dual boot and WinXP is not having this problem with the 8800 card. So, elementary... What's going on between Ubuntu and Nvidia? Best regards Gunnar

  • Am I getting Scheme wrong?

    - by nischayn22
    Inspired by the numerous posts about the importance of learning Lisp/Scheme I started to learn Scheme two days back, I am using the book "The little Schemer" and have completed half of it. But I still haven't learned anything new, the book teaches about recursion which I already understand and uses lambda (which I can think of a way to define a function in C). I still haven't got the concept of functional programming (please point to some example of functional compared to normal programming methods in C/C++ so I can get it). Am I learning in the wrong way? or is "The little Schemer" for a newbie in programming and I should look for some other books?

  • My first Windows Phone 7 application is live &ndash; from zero to submitted in 5 hours

    - by Eric Nelson
    Tuesday evening I found myself minus family. I decided to use the time to “have a crack at this Silverlight Phone 7 stuff”. From zero (no experience, no tools installed, no membership on the AppHub) to submitted for approval took me from 8pm to 1am – with the last hour messing around with png files in Paint to complete the submission process! Two days later on Thursday it was approved and is now in the marketplace for you to install - or not :-) The application is very simple but it works and looks “finished” – and importantly I learnt a lot about what is involved and the power of our tooling to make this pretty easy to get going. Go on, give it a go by popping over to the App Hub. You do need to pay $99 to join the App Hub to publish but you can start by downloading the free tools and just work with the included emulator.
