  • The technology behind 22can's curiosity

    - by Cameron Scully
    I don't have alot of experience with mobile apps and I definitely don't know much about MMO's but I was wondering what the basic architecture of a game like that would be (understandably some don't consider it a game, but it must use some game theory and implementation). Mainly, how are they able to send/recieve real time feed back of the cube being chipped away by thousands of players on their mobile devices? How is data of the cube's millions of pieces stored and accessed so quickly? Thanks

  • What is the impact of Windows 8 with UEFI on normal users?

    - by Sam
    I am a normal man-in-the-street computer user and so do not really understand what this is about, but I want to. Can someone please explain to me if: The Windows 8/UEFI secure boot thing will make it impossible to run normal/legacy applications in Windows 8 (as they will be unsigned)? It will turn Windows into an Apple-like system where only Microsoft approved applications can be run? As I say, I'm a normal user, and that is the overall impression I have from reading all the blogs, etc about it. If, on the other hand, all it does is make sure the system is booting a signed OS, how does this prevent malware (which is what at least two Microsoft blogs that I read seemed to be saying), given that most malware is not part of the boot process? The only way I can see this making sense is if it is ensuring that all OS components are signed. Is that it? Like I say, I'm a mortal, so please don't get technical on me, but rather explain how it will affect me, the user.

  • Implications on automatically "open" third party domain aliasing to one of my subdomains

    - by Giovanni
    I have a domain, let's call it www.mydomain.com where I have a portal with an active community of users. In this portal users cooperate in a wiki way to build some "kind of software". These software applications can then be run by accessing "public.mydomain.com/softwarename" I then want to let my users run these applications from their own subdomains. I know I can do that by automatically modifying the.htaccess file. This is not a problem. I want to let these users create dns aliases to let them access one specific subdomain. So if a user "pippo" that owns "www.pippo.com" wants to run software HelloWorld from his own subdomains he has to: Register to my site Create his own subdomain on his own site, run.pippo.com From his DNS control panel, he creates a CNAME record "run.pippo.com" pointing to "public.mydomain.com" He types in a browser http://run.pippo.com/HelloWorld When the software(that is physically run on my server) is called, first it checks that the originating domain is a trusted one. I don't do any other kind of check that restricts software execution. From a SEO perspective, I care about Google indexing of www.mydomain.com but I don't care about indexing of public.mydomain.com What are the possible security implications of doing this for my site? Is there a better way to do this or software that already does this that I can use?

  • Trainings for Back-end Programmer [closed]

    - by Pius
    I am currently working as an Android developer but I want to continue my career as a back-end developer. I consider my self having a relatively good knowledge of networking, databases and writing low-level code and other stuff that is involved in back- and mid- ends. What would be some good courses, training or whatever to improve as a back-end developer? Not the basic ones but rather more advanced ones (not too much, I'm self-taught). What are the main events in this area?

  • Using the right folder for the right job. Article link, please?

    - by Droogans
    There are specific folders designed for specific tasks. /var/www holds your web sites, /usr/bin contains files to run your applications...yet I still find myself putting nearly all of my work in ~. Is it possible to overuse my home directory? Will it come back to haunt me? Anyone have a good link to an article of best practices for organizing your files so that they are placed in their "correct" place? Is there even such a thing in Linux? I am referring specifically to user-generated content. I do not compile applications from source, I use apt-get for those tasks. This article has a great introduction to what I'm looking for. Table 3-2, "Subdirectories of the root directory" is the sort of thing I'm looking for, but with more details/examples.

  • Google Chrome "warn to quit" not warning on Cmd + Tab quit

    - by Theron Luhn
    As a Mac poweruser, I often use Cmd + Tab to switch between applications. Tab is unfortunately close to Q, so I often end up jamming Cmd + Q as well by accident. On most applications, this isn't a problem; a popup appears confirming if I want to quit, and I just click "cancel." However, this isn't the case with Google Chrome. I checked "warn before quitting", and when I press Cmd + Q a box saying "Hold Cmd + Q to quit" pops up. But when jamming Cmd + Q while switching to Chrome using Cmd + Tab, it completely ignores the "warn before quitting" policy and quits immediately. Any way to fix this annoyance? Switching either of the shortcuts to something else would fix the problem, but I'm not able to find a way to do so.

  • Free Software for Billing (Columbia)

    - by Yoimir Yamit Castrillon Duque
    English I'm looking for a billing application (also inventories, shopping, clients, providers, accounts, etc) for small businesses. The software should adapt with Colombia's necessities. I searched for it in Google, and I found several ERP such as OpenBravo and Adempiere, but these applications are very big and difficult to use, in fact, I couldn't make them work. I found an application called Ubifactura (made specifically for Colombia), I downloaded the Java source code, but I don't have any idea about how to compile it. I need someone to help me to compile it or just some recommendations for similar software. The idea is to help small business from my town with one of these applications (it doesn't matter if it is for Windows or Linux), the idea is to help. All help is welcome. Spanish (Español) Estoy buscando una aplicacion de facturacion (tambien inventario, compras, clientes, proveedores, cuentas, etc) para pequeñas empresas, que se adaptade a las necesidades de Colombia, en google encontre varios ERP como openbravo y adempiere, pero aplicaciones muy grandes y dificiles de manejas, de hecho no puede hacerlas funcionar. Encontre un programa llamado Ubifactura, hecho para facturar en Colomabia, descarge los archivos de codigo fuente en java, pero no tengo ni idea de como ponerlo a funcionar, pues habla de eclipce, de un servsdor CVS, que no tengo ni idea de como poner a funcionar, necesito si alguien me puede ayudar a trabajar con estos archivos java, o me suguieran aplicacion de acuerdo a mis necesidades. La idea es bebeficiar a varias pequeñas empresas de mi pueblo con una aplicacion de estas, ni importa si en entorno windows o ubuntu, la idea es aportarles algo desde el software libre. Saludos y a la espera de respuestas. Toda ayuda es bienvenida.

  • What is a good GUI text editor with code folding on Linux

    - by quanticle
    When I'm on Linux, I usually program using either gvim or emacs (depending on the language I'm working in, and the configuration of the machine). However, one thing I miss from the Windows world is code folding. Editors like Notepad++ and IDEs like Visual Studio allow shrink, or fold, blocks of code into single line headings. Are there any Linux editors with this facility? I know Eclipse can do code folding, but I don't want to launch Eclipse just to edit a HTML file.

  • Strange DNS problem [seems to be IPv6 issue]

    - by Homer J. Simpson
    Hi, I'm experiencing strange problems with my Kubuntu 9.10 when doing DNS requests from various applications. The requests are extremely slow, so loading any pages in Firefox or Konqueror, doing package installations in Kpackagemanager and other apps is really painful, while for example Opera doesnt have any problems, and ping is normally fast as well for DNS pings. I checked the proxy settings of both the used applications as well as of the general system and there are none, so to me it doesn't seem as there was something inbetween.. Does anybody have an idea on what to check for possible problem sources or how to solve this ? I'm behind a DSL home router which does the DHCP (and works well with my other computer). Any kind of advice would be really helpful. Edit: It seems to be some kind of IPv6 problem, as I could get it to work by disabling IPv6 explicitly in Firefox. Is there a general solution to this ?

  • SharpDX/D3D: How to implement and draw fonts/text

    - by Dmitrij A
    I am playing with SharpDX (Direct3D for .NET) without using "Toolkit", already finished with basic rendering 3D models. But now i am wondering how to program/create fonts for game (2D), or how to simple draw variable text to output with Direct3D? (it is not as SharpDX question as common Direct3D question, how to start with game GUIs? And what should i do to program simple GUI's like menu for a game (generally i understand that it's shaders).

  • Unity Launcher only runs once - requires lightdm restart before it runs again

    - by Don
    I have an intermittent problem that just started showing up several days ago. I am running 11.10 and all updates are current. I first saw the symptom with a custom version of the "Home" nautilus-home.desktop file I created in ~/.local.share/applications. I added a few static shortcuts to specific folders. What I found was, clikcing the icon once would open up my home folder, but after closing that nautilus window, clicking the icon again did nothing (did not even show icon backlight animation). However, I could right click on the same icon and access my short cuts as many times as I want. Symptom persisted until restarting lightdm. Just yesterday I saw the same sort of symptom happen with a custom launcher I created for a chromium-borwser to open a specific URL (with a few short cuts to other URLs). Click the icon - it works once. Then never again. Right click the icon and I can use the short cuts over and over - no problem. Note - at one point I assumed I might have a problem with my custom .desktop file, so I did a test by removing my custom nautilus-home.desktop. However, even after restarting lightdm, and verifying the home icon was the standard one from /opt/share/applications (all my custom shortcuts were gone) I saw the same symptom re-appear - it runs once and then not again until restarting lightdm. It seems to be intermittent and seems to move between various launchers. Not sure what to do or even what background data to gather. Attempt to improve question after the first answer: I tried the following: 1) remove all custom launchers 2) reboot 3) add custom lauchers back 4) reboot 5) attempt to use .... still have "runs once and never again" symptom with several launchers

  • Unable to bring back terminal launcher in fedora

    - by Sandeepan Nath
    Our office housing keeping guy sat on my linux (Fedora 7) system and somehow removed the main panel. By panel I mean where all the menus are there - Applications, Places, System etc. and contains a tab for every running application. I brought back the panel but now I don't see the terminal launcher and I can't find it anywhere. It used to be there in "Applications - System Tools - Terminal" but now the System Tools option itself is not present there. System - Preferences - Look and Feel - Main Menu. There one System option is unchecked but I can't check it and apply. I am logged in as root. How do I bring it back? Please help. This is very irritating and weird. That guy doesn't even know what he has done so no use of asking him. :)

  • Performance of concurrent software on multicore processors

    - by Giorgio
    Recently I have often read that, since the trend is to build processors with multiple cores, it will be increasingly important to have programming languages that support concurrent programming in order to better exploit the parallelism offered by these processors. In this respect, certain programming paradigms or models are considered well-suited for writing robust concurrent software: Functional programming languages, e.g. Haskell, Scala, etc. The actor model: Erlang, but also available for Scala / Java (Akka), C++ (Theron, Casablanca, ...), and other programming languages. My questions: What is the state of the art regarding the development of concurrent applications (e.g. using multi-threading) using the above languages / models? Is this area still being explored or are there well-established practices already? Will it be more complex to program applications with a higher level of concurrency, or is it just a matter of learning new paradigms and practices? How does the performance of highly concurrent software compare to the performance of more traditional software when executed on multiple core processors? For example, has anyone implemented a desktop application using C++ / Theron, or Java / Akka? Was there a boost in performance on a multiple core processor due to higher parallelism?

  • Create a AD-LDS partition under a child of the primary partition

    - by ixe013
    I have a AD-LDS instance running on a Server 2008 R2. I have this application partition, created at installation : dc=enterprise,dc=example,dc=com I have succesfully followed this procedure to create application partitions. They are named : cn=stuff,dc=enterprise,dc=example,dc=com cn=things,dc=enterprise,dc=example,dc=com If I configure my client(s) to follow referals, I can search from dc=enterprise,dc=example,dc=com and find objects under cn=stuff and cn=things. How can I create (or move after the fact) the stuff and things partitions so they are logically located under a OU under the initial partition, ending up with something like : cn=stuff,ou=applications,dc=enterprise,dc=example,dc=com cn=things,ou=applications,dc=enterprise,dc=example,dc=com

  • Gnome Shell Thunderbird Mail Notification

    - by Nerdfest
    Does anyone know of a way to get persistent Gnome 3 panel notifications in Gnome 3 in Oneiric? It's one of the few things holding me back from using Gnome 3 regularly. I've actually found a way of moving the notifications from the (usually) hidden bottom bar to the top, but it does not move the Thunderbird icon. The icon also only tends to appear the first time mail is received. I'm very surprised this basic piece of functionality doesn't exist for Gnome Shell.
