• On-line Based Conferencing For Admin Panel

  - by Tim Marshall

  Working on my admin panels work station section which will allow the admin to use simple office tools such as word editors, calculators and whatnot. Under this section of the admin panel, I would like to add a conferencing feature which will allow any administrator to connect with another administrator 1-2-1 under the 1-2-1 Conferencing section, or to join a meeting under 'live meeting' section. Upon my search for on-line based, I found there are all these, what seem to be great applications out there, however not all of them are on-line based, and come with a price! I would like to a purely on-line based conferencing/meeting/1-2-1 feature which will allow administrators to communicate via text or sound, stream their video, share their screen and sending of files. I know this sounds like a big feature, and I am not asking for someone to answer by programming one for my website! Does anyone know my best solution to progress to having this feature on my website, any tutorials or free to use, free to modify web plugins? Thank you for your help, Best Regards, Tim

• How to specify 'root' in path in text file

  - by DeanGrobler

  I'm following this tutorial located here on how to create a launcher for eclipse in unity. Everything is going pretty well so far, I've managed to successfully create the launcher but when I click on it, my system complains that the path to the exec is wrong. My exec for eclipse is located here: ~/opt/eclipse/eclipse And if you look at the tutorial you have to create a file and set it's contents like so: [Desktop Entry] Type=Application Name=Eclipse Comment=Eclipse Integrated Development Environment Icon=eclipse Exec=./opt/eclipse/eclipse Terminal=true Categories=Development;IDE;Java; In my case I have to provide the full location for the exec and there are a number of things that I tried that didn't work I set 'exec' to 'Exec=~/opt/eclipse/eclipse' , 'Exec=/opt/eclipse/eclipse' and 'Exec=root/opt/eclipse/eclipse' and none of these worked.. What should I set it to in order to fix the path so that my luancher works? Update------------------ I tried to list those 2 directories and what i get is this:

• Should I give up my cushy job to be tech lead for a startup? [closed]

  - by Katie

  I'm in my mid twenties, and I'm in a safe, comfortable job as a Software Developer. The work environment is great, I'm well paid, the benefits are good. I enjoy my job. Some friends passed my name on to some guys starting a new company. I had some informal chats with them and they liked me. They've asked me to joint their start-up as tech lead, designing and building their product from scratch. They're fully funded, and they know what they're doing. Taking the job would require giving up my safe, enjoyable, relaxed job for a risky, stressful, hard one, albeit with the potential to be really great in future. Should I take the job?

• Trick Ubuntu into resolving a domain name locally

  - by Matthew Brown

  I have an Ubuntu box that I use for all sorts of things. One thing I really want to do is redirect a sub domain to a local script. For example thisbit.example.com should actually show the content from localhost/~USER/FAKE.thisbit.example.com/ which is a folder that Apache is running for me which contains a very simple PHP script which implements an offline version of a server script that I am testing against. But example.com should continue to behave normally as should notthisbit.example.com etc. Ideally I need to be able to switch from testing to live with minimal fuss when the time comes.

• Lightweight Ubuntu

  - by Nick Berardi

  Just to start off, I know of lubuntu but it really doesn't meet what I am looking for. Basically what I am looking for is the standard Desktop Ubuntu install, but with out all the word processing, multimedia, and games installed. I have seen posts out about how to get the desktop environment running on Ubuntu server, but they seem complicated, and never seem to equal the standard Desktop install. So my question is, is there anyway to tell the standard Desktop install not to install all the applications? Or is there a distro available that leaves all the applications out, and just has the standard desktop look and feel? What I really want this for is, is for development purposes to run on a VM to do Mono development.

• RTOS experience

  - by Subbu

  I have been working as an embedded software engineer on mostly 8 bit micro-controller firmware and desktop/mobile applications development for the past five years. My work on a WinCE project (in which I got introduced to .NET CF) was short lived. I did use core APIs for interrupt processing, peripheral communication, etc...but again, not exactly a pure RTOS environment. In order to get together more solid experience for growing more in the embedded field, I want to work more with RTOSes. Will buying an evaluation board with an RTOS and putting together a project at home be regarded as a good experience or will an online course be more useful? I am just not clear as to what will be regarded as good experience. Any suggestions or directions will greatly help me. I have a passion for the field but just a need a point in the right direction.

• How can I link to callback functions in Lua such that the callbacks will be updated when the scripts are reloaded?

  - by Raptormeat

  I'm implementing Lua scripting in my game using LuaBind, and one of the things I'm not clear on is the logistics of reloading the scripts live ingame. Currently, using the LuaBind C++ class luabind::object, I save references to Lua callbacks directly in the classes that use them. Then I can use luabind::call_function using that object in order to call the Lua code from the C++ code. I haven't tested this yet, but my assumption is that if I reload the scripts, then all the functions will be redefined, BUT the references to the OLD functions will still exist in the form of the luabind::object held by the C++ code. I would like to be able to swap out the old for the new without manually having to manage this for every script hook in the game. How best to change this so the process works? My first thought is to not save a reference to the function directly, but maybe save the function name instead, and grab the function by name every time we want to call it. I'm looking for better ideas!

• Launch Rhythmbox using a Keyboard shorcut

  - by palerdot

  I use Rhythmbox all the time in my Ubuntu. Is it possible to have a custom shortcut like Ctrl+R in Ubuntu, which can launch the Rhythmbox window, even if it is playing in the background ? Since, the emphasis of Linux OS flavors is to use keyboards as much as possible instead of mouse, i thought this functionality might tremendously help me in my Ubuntu environment. The Keyboard shortcuts sections asks for a command; So, I'm not able to figure out how to give a custom keyboard shortcut to a program like Rhythmbox. I'm using 12.04 if that helps. Thanks.

• Windows 8 : 40 millions de licences vendues en un mois, l'OS démarre mieux que Windows 7

  Windows 8 : 40 millions de licences vendues en un mois l'OS démarre mieux que Windows 7 Microsoft a publié officiellement les premiers chiffres sur Windows 8. Un mois après le lancement du nouveau système d'exploitation le 26 octobre dernier, 40 millions de licences auraient été écoulées par l'éditeur. Quatre jours seulement après son lancement, Windows 8 avait fait état de 4 millions de mises à jour. Selon Tami Reller, directrice administrative et financière en charge de Windows et Windows Live, Windows 8 est plus rapide que Windows 7 en matière de mises à jour. Après la sortie de Windows 7 en octobre 2009, Microsoft avait un peu tardé avant de publier le...

• Is it possible to auto-mount sshfs

  - by Mark D

  Is it possible to auto-mount a remote FS using sshfs upon instantiating a proper VPN connection? Allow me to explain the scenario, I'm working remotely, to do that it helps if I can mount my home dir from a server in the office. To do that I need to vpn in. So within network manager I select the relevant VPN and connect. It connects but now I have to drop to the command line and mount my home dir on several machines. If I forget to do one machine my local dev environment isn't as efficient. I suppose I could write a quick bash script to do this but I'd rather get it running automatically when I connect.

• Chromium and Google Chrome downloading

  - by user286166

  Well, I have sincerely enjoyed having Google Chrome on my linux machine, and have never had any problems until recently. I found that Google Chrome will simply not allow redirected downloads to start. I can download from direct links, but not pages that redirect and "Start in 3 seconds..." I immediately assumed it was the webpage itself, so I refreshed many times. I then restarted the browser, and after another failed attempt, my computer. After that point, I suspected my internet provider was to blame. I tried the redirection link in an alternative browser (Midori), and it worked perfectly fine. I decided it must be the version of Chrome that Google put out, so I quickly installed Chromium, and to my dismay, ran across the same problem. I can live with copying and pasting the url into Midori for redirected links, but I'd like the convenience of staying in my main browser. Thank you for any advice in advance. c:

• Recovering a deleted partition

  - by Kishore

  I had a dual boot PC running Ubuntu 12.04 and Windows 7. About a month back, I deleted the Ubuntu partition via the disk management utility (I do not remember whether or not I formatted the partition after performing this action). I ran into some grub issues and used lilo to solve the issue. I followed the simple instructions described in this blog post. I now realize that there were some files in the Ubuntu installation that I need. Of course, I backed up the data, but not this folder apparently. Is there any way to get the data back? I tried following the process suggested on another post on askubuntu (suggesting the use of TestDisk), but was not able to even install TestDisk. The live USB I use is running Ubuntu 12.04 and it does not have a synaptic package manager. Installing from the terminal does not work because even after I type: sudo apt-get update sudo apt-get upgrade the command: sudo apt-get install testdisk fails to work.

• How do I get from a highly manual process of development and deploy to continuous integration?

  - by Tonny Dourado

  We have a development process which is completely manual. No unit tests, interface tests are manual, and merging and integration are as well. How could we go from this state to implementing continuous integration with full (or at least close to full) automation of build and test? We have a pretty intense development cycle, and are not currently using agile, so switching to agile with CI in one move would be a very complicated and expensive investment. How can we take it slowly, and still moving constantly towards a CI environment?

• Setting umask globally

  - by DevSolar

  I am using a private user group setup, i.e. a user foo's home directory is owned by foo:foo, not foo:users. For this to work, I need to set the umask to 002 globally. After a quick grep -RIi umask /etc/*, it seemed for a moment that modifying the UMASK entry in /etc/login.defs should do the trick. It does, too -- but only for console logins. If I log in to my desktop, and open a terminal there, I still get to see the default umask 022. Same goes for files created from apps started through the menu. Apparently, the display manager (or whatever X11 component responsible) does source some different setting than a console login does, and damned if I could tell which one it is. (I tried changing the setting in /etc/init.d/rc, and no, it did not help.) How / where do I set umask globally, so that the X11 desktop environment gets the memo as well?

• Cannot boot from Ubuntu USB

  - by Safi

  I create a ubuntu 10.10 bootable USB via the method that is described on the download page of ubuntu. I made that from windows and also from ubuntu 10.04 (I have dual boot). When I boot from the USB made, the menu shows and when I run it, it gives a beep and nothing else. It never boots. USB creation from both methods result the same. I downloaded ubuntu via the torrent provided from Ubuntu. Any help will be very appreciated. I want to make my USB just like a Live CD so that I can run it on some other computers also.

• Announcement: How-To Series Explaining Customizations Step By Step

  - by Oliver Steinmeier

  Yesterday we officially launched our new YouTube channel.  Today we are announcing another initiative that we have been working on for a while: to help you learn common customization tasks, we are going to publish a series of detailed How-To documents with lots of screenshots.  Many of these will also be the script for a YouTube video, giving you the choice to see it in action or go through the steps yourself guided by a PDF document. The focus of the initial set of How-Tos will be JDeveloper/ADF customizations, but over time we will expand into other areas.  Today's first document is meant to get everyone up to the point where a JDeveloper environment is up and running: a white paper that shows you how to set up JDeveloper, configure the integrated WLS domain, and make a very, very simple customization work. As always we are looking for your feedback.  Please let us know whether this is helpful for your work or learning, and what use cases you would like to see us document in these How-Tos.

• What are some non-MS languages that can write xlsx (Excel 2007+) documents efficiently?

  - by Honus Wagner

  Unfortunately, Excel format is required for the project I am working on. I have no problems getting the data I need in objects and arrays, and currently PHPExcel is doing handling the document generation. It works, but it's slow and loopy. Was wondering if there is a more efficient server language to generate Excel documents (not CSVs). This is a pure Linux environment so I need to stay away from .NET. I am open to any programming language that does it cleanly and efficiently. Thanks.

• Ubuntu Variant / Linux Distros which uses least system resources (RAM, CPU)?

  - by elegantonyx

  I have a netbook (an older Asus EEEPC 1005HA) which I want to get rid of Windoze on (I like Windows, but I don't think it works well in a netbook environment). Basically, my question is which Ubuntu variant will use the least RAM and CPU running idle, and/or the same question except when running Firefox and Libreoffice Writer, say. I am also open to suggestions of non-Ubuntu Linux distros, but since this is AskUbuntu I thought the first question would be more appropriate. I have a disk drive which I can attach to the netbook, so it doesn't have to be a Ubuntu Variant / Linux Distro which solely boots from a USB drive. I have at my disposal: DVDs, DVD writer/ disk drive, 4gb flash drive, 8 gb flash drive I was thinking either Lubuntu or Archbang / Crunchbang but I would like some help from more knowledgable people Specs: Can't boot into it right now, but I think I have either Intel Atom N270 @1.60ghz OR Intel Atom N280 @1.66ghz (single core, I think) 2gb RAM 160 GB hard drive

• How to write efficient code despite heavy deadlines

  - by gladysbixly

  Hi all, I am working in an environment wherein we have many projects with strict deadlines on deliverables. We even talk directly to the clients so getting the jobs done and fast is a must. My issue is that i'd always write code for the first solution that comes to my mind, which of course I thought as best at that moment. It always ends up ugly though and i'd later realize that there are better ways to do it but can't afford to change due to time restrictions. Are there any tips by which I could make my code efficient yet deliver on time?

• Missing feature in Hyper-V from Virtual PC

  - by Kevin Shyr

  One thing I really miss is the ability to create shared folder between host and guest.  Virtual PC does this well, you can create Shared Folder to be used every time, or just this one.  I have read some posts on how to do this.  Some people suggest using ISO Creator to package up the files and mount the image to DVD drive, but what I need is truly a "shared" environment, so I'm currently looking into creating Virtual switch and creating an internal network between the host and guest.  Let's see how that works out. I would have loved to give Virtual SAN Manager a try, but I don't have a local Fibre Channel to set one up. I guess this might be an extension to my original post:  http://geekswithblogs.net/LifeLongTechie/archive/2011/05/05/windows-virtual-pc-vs.-hyper-v-virtual-machines-vs.-windows-virtual.aspx
