• Windows 8 sera adapté aux puces ARM, Microsoft fait la première démonstration officielle de l'OS au CES de Las Vegas

  Windows 8 sera adapté aux puces ARM Microsoft fait la première démonstration officielle de l'OS au CES de Las Vegas Mise à jour du 06/01/2011 par Idelways Après plus d'un an de spéculations et de fuites involontaires (ou pas), Steve Ballmer vient de faire la première démonstration du successeur de Windows 7, et a annoncé que l'OS supportera en natif les puces ARM. On sait donc désormais que Windows 8 (bien que Ballmer ait fait très attention d'éviter de lui donner le moindre nom) fonctionnera sur une architecture System-on-a-chip (SoC), fournie dans un premier temps par NVIDIA et Texas Instruments.

  - by mark kaylor

  I'm running 12.04 Precise Pangolin, Kernel 3.2.0-32 w/ GNOME 3.4.2 I perused the prior questions/answers and did not find exactly the same problem, I am concerned that AUTOFSCK, Grub or some other critical event that needs some attention ? Any idea on how to get my video clean during boot? Once I get past the boot screen the video driver/card, etc is performing beautifully ! Here is a photo of the boot screen; nVidia GeForce CARD INFORMATION (lspci -vvv) 01:00.0 VGA compatible controller: NVIDIA Corporation G72 [GeForce 7300 LE] (rev a1) (prog-if 00 [VGA controller]) Subsystem: Gateway 2000 Device 3a07 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast TAbort- SERR- [disabled] Capabilities: Kernel driver in use: nvidia Kernel modules: nvidia_173, nouveau, nvidiafb Thanks for your help/advice.

• Ubuntu 12.10 doesn't boot (installed with wubi)

  - by Luna Kiyiya

  Quick and simple, my ubuntu doesn't want to load after installing with ubuntu. Starting the computer, at the screen to choose your operative system, first shows an error that windows failed to start, and later asks me to choose between ubuntu and windows. If I choose ubuntu, the same error happens again and I return to the same screen. If I choose windows, windows just starts normally as it was doing before I installed it. How can I solve this?? Thank you for your attention... I really need some help :)

• Silverlight : vers une fin programmée ? Microsoft ferme Silverlight.net, le site de référence sur la technologie

  Silverlight : vers une fin programmée ? Microsoft ferme Silverlight.net, le site de référence sur la technologie L'avènement du HTML5 a mis en mal les technologies de développement d'applications Web riches (RIA) comme Silverlight et Flash. Voici aujourd'hui pratiquement un an que Microsoft a publié Silverlight 5. Depuis, l'éditeur n'a plus fait mention d'une évolution de la technologie en dehors de la sortie discrète d'une mise à jour mineure (Silverlight 5.1). [IMG]http://idelways.developpez.com/news/images/silverlight-logo.jpg[/IMG] Par contre, Microsoft accorde une attention particulière à HTML5, qui occupe une place de...

• Learning to program styles? [closed]

  - by MrNewbProgrammer

  I'm a beginner programmer and I am currently developing an application of my own, just for the fun of it and learning to program. I'm building it from scratch, because I think that in this way I will learn the most. I have stumbled upon MVC's and CMS, CodeIgniter really got my attention, and the basic use is very straight forward. But I do not understand the inner workings completely. So I have decided that it might be better to just develop from scratch and maybe return to codeIgniter later, was that good decision? Would it be better to use CodeIgniter and learn from that?

• Most underestimated programming tool [closed]

  - by Anto

  We have many great tools which helps a lot when programming, such as good programmers text editors, IDEs, debuggers, version control systems etc. Some of the tools are more or less "must have" tools for getting the job done (e.g. compilers). There are still always tools which do help a lot, but still don't get so much attention, for various reasons, for instance, when they were released, they were ahead of their time and now are more or less forgotten. What type of programming tool do you think is the most underestimated one? Motivate your answer.

• Do games use threads?

  - by Nubcake

  I understand that the concept of how a game runs i.e while (game_loop = true) { //handle events // input/output/sound etc } But it has come to my attention while programming in another HLL is do some games use threads for certain operations? For example take any Pokemon game ; during interaction a textbox appears to display information. Now I've been trying to simulate that sort of textbox and the only way I could have got it to be exactly the same is by using a loop and yes once a loop is started there is no way to handle window events unless they are handled again inside the loop itself. I couldn't have used this loop inside a different thread other than the main one (due to a DirectX limitation) so the only option was to use it inside the main program thread. I was wondering if some games work like this ; do they only use the main program thread and handle events again if they're inside a loop? Edit: I forgot to mention this is about console games not PC games! Thanks Nubcake

• C# TextBox Autocomplete (Winforms) key events and customization?

  - by m0s

  Hi, I was wondering if it is possible to catch key events for auto-complete list. For example instead of Enter key press for auto-complete use lets say Tab key. Also is it possible to change the colors and add background image for the auto-complete pop-up list? Currently I have my own implementation which is a separate window(form) with a list-box, which works OK, but Id really like to use .net's auto-complete if it can do what I need. Thanks for attention.

• MySQL queries - how expensive are they really?

  - by incrediman

  I've heard that mysql queries are very expensive, and that you should avoid at all costs making too many of them. I'm developing a site that will be used by quite a few people, and I'm wondering: How expensive are mysql queries actually? If I have 400,000 people in my database, how expensive is it to query it for one of them? How close attention do I need to pay that I don't make too many queries per client request?

• professor of Java not knowing Groovy or Scala, normal or abnormal

  - by user311884

  i went to a prestigeous software conference (as dominant in its own field as MS in general), one main speaker is a professor of computer science who has been teaching Java for 20 years. During question session, he seems never heard of Groovy or Scala.... He is from a decent University in US... Is Groovy or Scala too new to attract academic attention or is this professor abnormal? thanks.

• Is there a Delphi dropdown notification component?

  You know how in Firefox, if something happens that requires your attention but isn't immediately urgent enough to require a modal dialog, it will drop down a little strip at the top of the tab with a question on it? I'd like to be able to put functionality like that in a Delphi app, but I don't know if there's a component for that. Does anyone know of one?
