• Mic not working when vga connector removed

  - by yygyt

  I have a computer that should run continuously without any connection to a monitor. For developmental purposes I have been keeping the vga connection with the monitor and experienced no problem until now. When I start the machine removing the vga connection beforehand, external microphone does not work. At first I didn't know anywhere to look and see the problem, but after a google search I saw that there is a command as alsamixer I ssh the machine end type alsamixer when it is connected to the monitor, here is the result If I remove monitor connection and reboot again, and then type alsamixer, I see the error, $ alsamixer cannot open mixer: No such file or directory I suspect that this error is related to X somehow. I really don't know anything about what goes beyond. This machine needs to work without any connection to a monitor. I would deeply appreciate any suggestions.

• Nautilus won't browse my USB hard drive unless I double click it twice.

  - by agnul

  On my laptop, running 10.10, whenever I plug in a thumb drive Nautilus will add an icon on the desktop and open a file manager window with the drive contents. This does not work for my 250Mb external hard drive: the icon is added on the desktop, but no file manager window pops up. Double clicking on the icon just causes some disk activity (on the system drive) and nothing else. Double clicking another time on the icon the file manager eventually opens. At first I thought this was related to nautilus-elementary, but after removing nothing has changed. How do I even start debugging this?

• I just updated to 12.04 from 11.10 and now the Unity bar is very sluggish and even the menus do not show on the panel

  - by jredkai

  Like the title says, I just upgraded to 12.04, I know it is only beta but I'm having problems with the Unity bar and the panel with the menus. First the Unity bar is acting very sluggish..I really don't know how to explain it. Also with the menu at the top, it keeps a strange little black bar on everything, even across my tabs in Firefox, it also doesn't let me see any of the menus, well they flicker and you sort of have to guess where everything is. I'm at a loss, I've already ran updates a couple of times to see if I missed something. I really hope I don't have to completely redo my whole Ubuntu setup. Any help would be greatly appreciated.

• Learning to program in the modern era?

  - by BBHorus

  At this time, lets say in the modern era, in which order do you organize a programing course for teaching and/or learning, what should be learned first, what should emphasize: Databases Data structures Design patterns Programing paradigms(Procedural, functional, OOP, ...etc ) Operating System Some specific programing language What about English if you are not native speaker or doesn't know English AI Anything else... I ask this because in the university that I went, the programing course was awful it was not focus on what you were going to see out when you work what you were supposed to learn. PS: Again sorry about my English is not my main language. ...Experts and gurus please share

• Beginner flash game development: Start with framework or from scratch?

  - by captaincomic

  I want to write some simple flash games (as a hobby). I have a lot of programming experience, but no experience with Flash/ActionScript. My question is: As a beginner, is it a good idea to start with a framework like Flixel, FlashPunk or PushButton or would it be better to write my first games from scratch? Also, if you vote for using a framework, which one would you recommend? What are the differences? And another question: What about Flex, would you recommend using it?

• New "How do I ..." series

  - by Maria Colgan

  Over the last year or so the Optimizer development team has presented at a number of conferences and we got a lot of questions that start with "How do I ...". Where people were looking for a specific command or set of steps to fix a problem they had encountered. So we thought it would be a good idea to create a series of small posts that deal with these "How do I" question directly. We will use a simple example each time, that shows exactly what commands and procedures should be used to address a given problem. If you have an interesting "How do I .." question you would like to see us answer on the blog please email me and we will do our best to answer them! Watch out for the first post in this series which addresses the problem of "How do I deal with a third party application that has embedded hints that result in a sub-optimal execution plan in my environment?"

• Creating a Lazy Sequence of Directory Descendants in C#

  My dear friend Craig Andera posted an implementation of a function that descends into a directory in a "lazy" manner, i.e. you get the first descendant back right away and not after all descendants have been calculated. His implementation was in Clojure, a Lisp variant that runs on the Java VM: (import [java.io File])(defn dir-descendants [dir]  (let [children (.listFiles (File. dir))]    (lazy-cat      (map (memfn getPath) (filter (memfn isFile) children))...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• 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.

• What's a good model for continuous manager <-> programmer feedback?

  - by MebAlone

  Is it important for managers to give devs regular feedback on how they're doing and vice versa? I say vice versa because I consider employees to be responsible to their manager, and managers to be responsible to their employees. Everyone seems to think this is a good idea but in practice I rarely see it happen because so many shops are "agile" now and that usually means a daily standup plus a weekly kickoff, etc. So one-on-ones just don't happen. In my last position I had my first one-on-one w/ my manager 6 months after I'd been w/ the company. It turned out there was lots of misunderstanding, misalignment and confusion built up and snowballed. Not really surprising when there's no direct personal communication for that long.

• Interface design where functions need to be called in a specific sequence

  - by Vorac

  The task is to configure a piece of hardware within the device, according to some input specification. This should be achieved as follows: 1) Collect the configuration information. This can happen at different times and places. For example, module A and module B can both request (at different times) some resources from my module. Those 'resources' are actually what the configuration is. 2) After it is clear that no more requests are going to be realized, a startup command, giving a summary of the requested resources, needs to be sent to the hardware. 3) Only after that, can (and must) detailed configuration of said resources be done. 4) Also, only after 2), can (and must) routing of selected resources to the declared callers be done. A common cause for bugs, even for me, who wrote the thing, is mistaking this order. What naming conventions, designs or mechanisms can I employ to make the interface usable by someone who sees the code for the first time?

• Where are my Hard Drives/Local Disks on the COMPUTER/System Folder in Ubuntu 12.04?

  - by Russel

  Being first to try Ubuntu. But Where are my Hard Drives/Local Disks on the COMPUTER/System Folder in Ubuntu 12.04?! Before installing 12.04 i had tried the Ubuntu 10.10 Version Live and it was perfect in showing my Local Disks. But it couldn't recognize my GTX 470 Graphics driver so i thought of trying the recent version i.e 12.04. Fortunately it solved the Graphics driver thing but now i am stuck with finding My Local Disks on 12.04. I am sorry if this is a silly question, but i know nothing of Ubuntu at the moment. Regards,

• RIA Services and Entity Framework POCOs

  WCF RIA Services contains a special domain service for entity framework which will automatically be used if you use the Domain Service template in Visual Studio. This winter I tried the template with a few projects. One of them had EntityObjects and the other had POCO entities. The EntityObjects worked great, but the POCO entities didn’t work at all. The bulk of the problems were based on the fact that the EntityDomainService used methods from the first version of Entity Framework that relied...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Problems in detecting pen drive

  - by Mzk

  First of all, I don't have an issue with detecting my pen drive on 32-bit ubuntu 12.04. It can detect my pen drive very fast when plug in. Then, I bought a laptop installed with windows 7 64-bit operating system. I have decided to installed ubuntu alongside with win7. To be precise, I installed uBuntu 12.04.3 64-bit. It appears that every time I plug in my pen drive, it is either very slow automatically mount. It is even worst that the pen drive won't mount when plug in to usb 3.0 port. Anyone? UPDATE: My laptop can detect pen drive now either 3.0 or 2.0 port. The question is why the pen drive very slow shows up?

• Bluetooth issues after Saucy upgrade

  - by charlie

  I upgraded from Raring to Saucy, and now my bluetooth is giving me problems. First, even though I have a bluetooth inbuilt in my laptop, which I prefer to keep off unless I am using it, there is no greyed out bluetooth icon in the notification area. This was present in Quantal, but was missing in Raring too. I was hoping to get this fixed in Saucy. Seems otherwise. Secondly, and more importantly, in saucy when I am turning on my bluetooth, it immediately (or within seconds) turns off automatically, without giving me any time to even make the device visible. Please help!

• *raine Trip Report (Lorraine & Ukraine)

  - by delabassee

  Last week, I had the opportunity to talk about Java EE 7 in Nancy (Lorrraine - France) and Kiev (Ukraine). The first event was arranged by the local Lorraine JUG while the second one was a largest conference organised by the Ukraine Java User Group. Based on the overall feedback and discussions I had during those two events, it is clear that the WebSocket API (JSR 356) is really a hot topic. And travel issues aside, I have really enjoyed my time during those two events. Thanks to both JUGs for having me! A more detailed report can be found on my personal blog.

What are the exporting options available on Google scholar web site and how do they work?

• UbuntuStudio 12.04 does not boot after install - no "intrd" image

  - by user72705

  After installing Ubuntu Studio 12.04 from DVD onto the fourth hard disk, it fails to boot, even when explicitly choosing the fourth hard disk as the boot device. I have SUSE 11.2 on the first 2 SCSI disks (which form a RAID) and Studio64 on the 1st IDE disk (that is, the third disk). Looking at the /boot directory on the Ubuntu partition, I see there is no initrd image. Editing the GRUB configuration file to include (hd3,1)/vmlinuz and of course (hd3,1)/initrd should fix the problem. But still GRUB gives a file not found error. This appears to me that, no mkintrd during the booting process (checked with LiveCD) runs like in OpenSUSE. How do I create the initrd to make Ubuntu bootable.

  I am trying to install Ubuntu Desktop 12.04 on my laptop. It just failed on the entry selection step(to select installation or try it first). However, when I tried it on my desktop computer, the installation went smoothly . I've thought of that and got a few clues.

PS: My laptop is ASUS K42J, RAM size is 2G. I am using liveusb to create the usb stick.

• How well supported is the ATI graphics on a Sony VAIO SA?

  - by whoami

  This is the first time i will be buying a laptop/desktop to use as a Ubuntu platform with ATI. Now i did notice a while back that ATI drivers were not in cahoots with Linux as of yet. I am just wondering if any one is still experiencing ATI issues, or this is no longer the case. I am looking to spend money on a laptop Upgrade, but I don't want to spend a screw load of money just to find out I can only use windows and my Graphics driver does not work. So the Question is: What's ATI Support like on Ubuntu 10.10 Here is what im thinking of buying http://www.gadgetfreak.gr/wp-content/uploads/2011/02/SB_S08_keyboard_B_us_FP-1024x716.jpg, If any one has the Sony VAIO SA Series and installed Ubuntu on it, please do share your story, about driver problems. On a side note my old Sony S-Series which im using now, i never got the fingerprint reader or the webcam working on it, has any one been able to do this for the new models? I preferably dont care about the fingerprint reader but do care about the webcam.

• Boilerplate Terms & Conditions for web app? [closed]

  - by Louis Bataillard

  Possible Duplicate: What are some good resources for generating privacy policies and terms of use? I am just about done creating my first web application. Since the application stores some user data, I want to make sure that I can not be held liable should something bad happen to the site. I googled around but I could only find boilerplate T&Cs for websites, not for web apps. Does anybody know where I can find such a boilerplate agreement that I can use? I realize that this won't be 100% security, but it's better than nothing I suppose.

• What does well written, readable tests look like?

  Doing unit testing for the first time at a large scale, I find myself writing a lot of repetitive unit tests for my business logic. Sure, to create complete test suites I need to test all possibilities but readability feels compromised doing what I do - as shown in the psuedocode below. How would a well written, readable test suit look like? describe "UserEntity" -> it "valid name validates" ... it "invalid name doesnt validate" ... it "valid list of followers validate" ..
