• Ubuntu and WiFi Network

  - by Anonymous

  I have been trying to figure out this problem. I am currently dual-booting Ubuntu with my Windows machine. My Ubuntu would connect to my wireless router but it cannot access any web pages nor ping any hosts. Wired connection works just fine. My Windows OS in the same machine (with the exact same network configuration as my Ubuntu machine) connects and works fine. I don't know why Ubuntu cannot access the Internet. Any ideas?

• Flash rend la navigation instable sous Android 2.2, Apple a-t-il finalement raison de boycotter cett

  Flash rend la navigation instable sous Android 2.2, Apple a-t-il finalement raison de boycotter cette technologie ? Brian, journaliste pour PocketNow, vient de publier une vidéo dans laquelle il compare la navigation Internet de l'iPhone, du Nexus One et du HD2 d'HTC. Il surfe sur les mêmes sites web avec les trois smartphones, et compare leurs navigateurs. Sur le Nexus One, il a installé Froyo accompagné de la beta de Flash permettant de lire pratiquement tous les contenus Flash. Les images montrent que les jeux Flash tournant avec un bon processeur sont très proches des standards, écrits en natif. Cependant, alors que la vidéo avance, les choses changent. A 4min30, Flash devient plus agité lorsqu'il est sur une pag...

• ASP.NET Website Security Tips and Tricks

  This is a tutorial on how to secure your ASP.NET Mono website. Securing an ASP.NET website that runs in Mono is very different from securing an ASP.NET website hosted in a Windows environment because an ASP.NET Mono website runs on a non-Windows server such as Apache or Lighttpd and on an operating system such as Linux Unix. Thus the principles of securing a website in Apache server can be applied to securing an ASP.NET that runs in Mono.... Comcast?

• Can't connect to wireless without typing sudo modprobe b43 in terminal

  - by user90889

  I just upgraded to 12.04 on an old ACER Travelmate 5320 using Broadcom 4311. I wasn't able to connect to the internet through the wireless for a few days. It didn't even display wireless networks. I was finally able to make it work by following the instructions found here: http://linuxwireless.org/en/users/Drivers/b43#supported However, each time I log on to the computer I have to go to the terminal and type sudo modprobe b43 to make the wireless work. Is there somehow I can avoid this? I have used Ubuntu for many years but always relied on other people to help me with the technical stuff. The terminal is alien to me so I literally follow online forum instructions without knowing what I'm doing. Also, I tried many many things before I managed to make it work. So I'm worried I may have installed something that now conflicts with whatever the sudo modprobe b43 does. Thank you

• I can't login to facebook from any browser

  - by user92974

  I'm Using UBUNTU 12.04. I'm having problems with Facebook. It really hard to login. Takes like 3 or 5 min. At first I thought it was a flash problem but then I realized it could be some proxy's conf file. Other sites doesn't have problems. Yesterday I tried Tor-browser-bundle and I installed privoxy using this rules http://www.neilvandyke.org/privoxy-rules/ . Today I removed privoxy and the conf file with the Ubuntu software center and ubuntu-tweak. I don't really find the problem and my windows pc does not have any problem with the same modem. I don't have an ISP'S PROXY it just a direct Internet connection using automatic DHCP. Maybe I am missing something else. But I want to be sure so, I'm asking. PD: Sorry for my English I'm Argentinian.

• Settings object with singleton pattern

  - by axis

  I need to build an object that will have only one instance because this Object is dedicated to the storage of vital settings for my application and I would like to avoid a misuse of this type or a conflict at run-time. The most popular solution for this, according to the internet, is the Singleton pattern. But I would like to know about other ideas or solutions for this; also I would like to know if other solutions can be much more easy to grasp for an user of this hypothetical library. Thanks.

• Beginner help: where to begin [closed]

  - by shad

  I want to learn how to program. A main stream programming language such as Java, C++/C# is my primary target. Currently, I am a high school student planning to take programming, Digital electronics courses next semester. My biggest problem is that I do not know where to start and I have no one to consult with. Should I take a course at my local community college this summer? Get some books or try learning from some internet websites? What would be the best option a book or website? note that this is no longer my words, but rather ChrisF's because he decided to reword the question a bit (bad) and spaced it out better (good).

• Dell Latitude D830 DVD Drive Not Recognized

  - by DragonFire

  Unlike some people who have issues with the video or WiFi drivers, I suffer from not being able to use the DVD drive on this laptop. Upon POST, the BIOS sees it and I am able to open the tray as well; however, once the system starts to load up Ubuntu or other distros (Debian and Linux Mint), I lose all functionality. Plus, I don't see it listed as a device in the OS. I've poured over the internet the past few days trying to see if anyone else has the issue, or did and found a solution but sadly, nothing anywhere so far. So, I thought I would ask the community here and see what you all think. Worse case scenario, I have some dead weight to a nice little machine. Thanks! PS I honestly think Linux doesn't like the IDE interface the disc drive has.

• Google abandonne progressivement Windows en interne, pour des raisons de sécurité

  Google abandonne progressivement Windows en interne pour des raisons de sécurité Selon le Financial Times, Google demande à ces employés de cesser progressivement l'utilisation l'ensemble des systèmes d'exploitation Windows, et cela pour des raisons de sécurité. Toujours selon ce journal, cette décision qui date depuis janvier dernier, vient suite aux attaques chinoises contre le moteur de recherche qui ont eu lieu la fin de l'année 2009 causées par une faille de sécurité dans Windows XP et le navigateur Internet Explorer 6. Donc depuis janvier dernier, les nouveaux employés de Google n'avaient le choix qu'entre un PC équipé d'un système Linux, et un Mac. Et Windows n'était toléré que sur les ordinateurs po...

• Is there a way to develop desktop software using PHP?

  - by user1492018

  I have to develop a real estate marketing CRM software for my client - where the application is installed on desktop but can also be accessed from web. 2 reasons why they want the application to run from desktop : So that it can work with/without internet connection They don't want their complete data to be online They want to access few of the data like property listing & inquiries (managed from desktop application) from their website through secure login & password. The data that is entered in desktop application should be automatically synchronized with the website application. I was wondering if there is a way to develop this kind of software using PHP & MySQL. If yes, it will be great if anyone can provide me the referral link.Else please suggest, which language should I use.

• Is it possible to change the group list shown on the application launcher?

  - by Grobbendonk

  I just installed Unity, on Ubuntu 10.10, to try it out. I've tried fiddling with a few things, but I can't work out how the applications are grouped and listed. I mean - if I click on the Applications in the launcher, we get the list of applications installed, with the option to narrow the selection by group. i.e. |Search box|All applications|Accessories|Games|Internet|Media|Office|System| My question is where that list is generated - my machine is mostly for work, so the games have been uninstalled (and I get a "there are no games on this box" message, which is nice), and there's a stack of other stuff I'd like to see under a new group of "work" or something. Obviously, a logical follow-up - how does unity know how to classify the applications into those groups? Is it the info in the .desktop links to them?

• FxCop / Code Analysis with VS2010 Ultimate

  - by Cuartico

  I've getting some information about this, but I still can find a proper answer, I was asked recently in my company for this : "run a fxcop analysis on that code and tell me the results". Ok, I have VS2010 Ultimate which has code analysis, but before making any comment, I browse it on the internet cause I want to implement the best choice... So, let's say I'm gonna use the same rules on both analyzers: Should I recommend using one above the other? Should I say "hey, thats kinda old, let's use code analysis!" Should I get the same results on different computers? (for what I undersand, fxcop gives you some "points" and for what I've read, sometimes it gives you diff points on diff computers, I don't know about this with code analysis Thanks, any help would be appreciated

• How to stop running pidgin at logins and disable window hiding feature?

  - by Behzadsh

  Every time I login into my desktop, pidgin start behind, and sometimes it's bothering me - e.g. when I'm not connected to Internet or when I don't want to be on-line - I check startup application list and there's no pidgin listed. another thing that is very bothering is hiding window feature or what ever it called. assume that you're using MusicTracker plug-in, your status is Busy and you're chatting with someone. when music change, status will change, and then buddy-list will disappear and chat window will minimize. Buddy-list is not important but minimizing chat window when you're chatting is bothering, Is there any way to make pidgin stop that?

• Les offres d'emplois cadres se tassent aussi dans l'informatique d'après l'APEC, le secteur progresserait même moins vite que la moyenne

  Les offres d'emplois cadres se tassent aussi dans l'informatique D'après l'APEC, le secteur progresserait même moins vite que la moyenne Avec un peu plus de 52 000 offres d'emploi cadre confiées à l'Apec en mai 2012, l'évolution mensuelle du marché de l'emploi cadre a connu une quasi-stagnation, avec +1% par rapport à mai 2011.

• Using a GPL licensed library in a commercial app

  - by user577616

  I develop an android application and in my app I use a libary (jar) that I download from the internet. This jar is open-source under the "GNU General Public License v2". I tried to read the text of the license but had difficulty understanding it. My question is: can I use this libary without changing nothing in the jar in a commercial application? I will be making profit from selling my app which uses this GPL-ed .jar file. If possible, I would like to avoid converting my application to open-source.

• Is there any Ubuntu translation indicator?

  - by Oyibo

  For more precision: I'm runnning Ubuntu 12.04 I'd like an indicator which shows up to the left of the date/volume/wifi icons If possible I'd like to be able to change the translation language The indicator could use internet based translators (google translate etc.) or have a complete library come with it so translations can be obtained offline. Relating to usability: I'd like to have it work in a way where you click on the indicator icon and you can start typing either directly or once a window has opened and it instantly shows the translation you need (with your target languages pre-set or determined in options).

• Setting up wireless drivers in Ubuntu 9.10?

  - by xdya

  I've just installed ubuntu to a notebook, deleting the windows xp that was installed before, so now nothing works I couldn't solve the problem of getting the blank screen with the versions 12.. and 10.. so now there is 9.10 installed, which works fine. Well, it boots up at least. I can't get working the drivers though. I'm totally new to linux, and I've read in some forums that in this version you have to install all of them yourself, because the system won't detect them automatically. Therefore I tried to find the drive for my wireless card, but actually I have no clue how to get it work. Could someone please help me out? So here are the specs: System installed as mentioned: Ubuntu 9.10 Computer: Acer Aspire 3100 Wireless according to laptop specs: 10/100 Fast Ethernet, Wake-on-LAN ready, Acer InviLink™ 802.11b/g Wi-Fi CERTIFIED I would really appreciate some detailed description to setting up my internet Thanks!!

• Run 3 monitors on two different video cards?

  - by hullot

  Can I run 3 monitors on two different video cards? I have an ATI and Nvidia brand card. The ATI has 2 HDMI connections. They both work. Both cards are also picked up in Windows, one being the ATI and the other one as the Nvidia, but it says VGA Controller, although the card only takes 2 DVi. So, one DVI cable goes into that Nvidia card. 3 Monitors, but only 2 the HDMI ones from the ATI pick up, not the third one which is connected to the Nvidia via DVI. How can I run three monitors then? I suppose I can't install both drivers, so I'm unsure what to do. Is this possible? I just want the Nvidia card to power the third screen, no gaming on it, nothing. Also the ATI is picked up as primary card as well, so no hurdle there. EDIT: Hm, just installed the Nvidia drivers and it picked up the third screen no problem. Hope there aren't any major conflicts. Will post this as an answer as correct when I'm able. Can't as a new user.
