  • How to make xlock use the first key I hit as a part of my password

    - by alesplin
    I just switched from Arch Linux to Ubuntu 10.10. I'm running the Fluxbox window manager, and I use xlockmore to lock my screen with the following key shortcut: 192 :Exec xlock-mode marquee +usefirst -icongeometry 240x240 -message "back in a minute..." The problem I'm having is that xlock is definitely not using my first key as part of my password. Instead, it uses some randomized fade pattern to fade to the password screen. I find this highly annoying, as when I get back to my desk and start entering my password it doesn't register password characters until the fade pattern is complete. I've also tried the following modifications with no difference: 192 :Exec xlock -mode marquee -usefirst -icongeometry 240x240 -message "back in a minute..." 192 :Exec xlock -mode marquee -icongeometry 240x240 -message "back in a minute..." The first example worked flawlessly on Arch. Does Ubuntu have some sort of system default that you can't override on the command-line?

  • Meta Description or Title For Post Contents

    - by Raj
    I have a site that has posts without titles. You can think of them as being a lot like Twitter tweets. Should I put the post contents in the meta title tag or the description tag? If I put the post contents in one of the tags what should I put in the other? My challenge is that we have very short amounts of content with no titles. I want to avoid having too many duplicate titles or descriptions. We have things like user name, full name, date, etc.

  • Web development for people who mainly do client side..

    - by kamziro
    Okay, I'm sure there are a lot of us that has plenty of experience developing c++/opengl/objective C on the iPhone, java development on android, python games, etc (any client side stuff) while having little to no experience on web-based development. So what skillset should one learn in order to be able to work on web projects, say, to make a facebook clone (I kid), or maybe a startup that specializes on connecting random fashionistas with pics etc. I actualy do have some experience with C#/VB.net back-end development a while back, but as part of a team, I had a lot of support from the senior devs. Is C# considered a decent web development language?

  • Multiple Document Interfaces in Visual Basic

    What is Multiple Document Interface (MDI)? In most VB.NET applications, it is using a single document interface (SDI). In this type of interface, every window is unique to aother window. But in multiple document interface, it works by having one parent window with child windows under it. See the screenshot below: As you can see, there is one parent window (in gray color) and there are 3 child windows (in blue, violet and orange color). You can have more than 3 child windows depending on your application requirements. But you can only have one parent window. Depending on the design of your MDI...

  • Using a back-end mechanism to copy files to DB and notify the application

    - by BDotA
    This Scenario: User copies large files to a local folder. I want to watch that folder and when a new file is dropped then go and copy it to Database, so later when coping is done I can actually use it in my application. ( A C# WinForms App). It would be awesome to also find a way to somehow get notified in the Application that hey copying the file to DB is finished and ready for use... I am using C#.net, Windows... What solutions/architecture do you suggest for this? For example having a windows service running all the time watching that folder, when something copied goes and write it to DB ... then how about getting notified? MSMQ is something I can use? don't know much about it yet. Thanks.

  • Are there any good guides for making mods for Minecraft?

    - by Pureferret
    I've been coding in Java for 5 months at work now, and having past experience with programming in other languages, modifying existing code at Uni etc. I feel like I want to get started on (read: continue learning to program by) modding with minecraft. I know what I need, but not exactly how to do so. I once saw some good guides on the minecraft forum, but they all explained how to write in java, hows different classes in the code work etc. I'm more interested in how you decompile the code, write your own separate from the main 'trunk' of minecraft and then package it to install with a tool like 'Magic Loader'. My issue with these guides is that they always relied on being in windows, but I'm primarily a linux user, and the guides on the forums only seemed to assume you were on a Windows box. So is there a good 'walkthrough' for modding for Minecraft? Especially one where it assumes or at least allows for the fact you are in linux?

  • How much time do you spend in this site with work on your desk?

    - by David Conde
    This is a simple question, because I want to see if there is a collective tendency to do this: How much time do you spend snooping around in StackOverflow, Programmers, and all those heavenly sites even when having work on the desk? Are these sites becoming facebook, in our case? I used to enter facebook from time to time... it's been like 20 days now and I dont even care about it. All I want to see is what are the latest post of my geeky friends around here..! Is this collective?

  • 2D management game [on hold]

    - by Simon Bull
    Very newbie question but I have a game idea in mind. It will be 2d and data centric, like football manager. However I am struggling to find a platform that would suit. I am an experienced line of business developer so am happy to write code, but I would like a platform that does some of the leg work for me so was avoiding OpenGL. I would also like to be able deploy to iOS, android, windows and OS X. What are the options? To be more clear, the game is not a normal platform or shooter type game, so game maker is likely to be way too basic and unity seems a little over the top (though I am not sure if the GUI options would fit?). The majority of the game is more like business screens just displaying data and having buttons to click. Are there options for this type of game (May help to look at football manager)?

  • Interacting with IE using sendkeys from Excel

    - by Thomas Egan
    I'm trying to write an application which uses values from excel and then switches to a web application using sendkeys. The problem I am having is that I cannot used sendkeys ("{ENTER}") or sendkeys ("^o") as I don't have the access for that. I'm trying to automate a very trivial admin task. I've thought about using the mouse to interact with the links as well as pausing and waiting for the user to just hit return but so far have been unable to come up with a solution. Do you think there is anyway around this? I have some VBA knowledge (enough to get me this far) but not a great deal.

  • Clock drift even though NTPD running

    - by droffo
    I'm having a problem with the clock drifting on my PC. I'M running Ubuntu 10.10 on an somewhat crusty IBM e-server (1.5GB RAM, 2.4GHz CPU) ntpd is running (started at run level 2) servers are defined: server 1.us.pool.ntp.org server 2.us.pool.ntp.org server 3.us.pool.ntp.org server time.nrc.ca server ntp1.cmc.ec.gc.ca server ntp2.cmc.ec.gc.ca server wuarchive.wustl.edu server clock.psu.edu Looking at the log file, it would seem that the ntp daemon is running, but the system clock never seems to be set, however. If I manually set the time from a Casio "atomic" watch, the date/time displayed by the Clock applet drifts out of sync over time. Looking at the log file (below) it would seem the ntp daemon started ok and is running. So I am totally flummoxed right now :-( Here's a copy of my ntp.log file.

  • Changes to 'resolveconf' discarded when connecting to a new network

    - by sudheer
    I have upgraded to 12.10 from 12.04 recently and I am having issues with connecting to the Internet. I got an IP address and am able to ping other LAN IPs in the local network but I am unable to connect to the Internet and am even unable to ping www.google.com from a terminal. Somehow making changes in /etc/resolv.conf and restarting resolvconf service and rebooting works but I need to do this every time I connect to a new network. How do I make these changes permanent? Can someone suggest a solution to this issue?

  • Developing a DVR software using a hardware KIT

    - by Leron
    I'm currently thinking about a project for my masters degree graduation. I start researching for options to make my own video streaming software based on a premade hardware kit having not much knowledge about what I'll exactly need that will match my needs. My search led me to the DVR (Digital Video Recorder) cards which seems to be the closest to what I need, but still I can't find out a few basic things so I decide to ask for them here. Currently I haven't find a lot of manufacturers that offers such kits so where I can look and have some options to choose from? There are a lot of DVR products on the market but they already have a software written for them and even if I buy one they just don't give any documentation or sdk's so buying such is not an option I need a DVR card made exactly for software programers and not end users. Are there a preferred manufacturers that provide such kind of devices with good and developer-friendly documentation? Also - I prefer to do all this with Java, is this an option (I think I will make it with .NET too but really prefer Java as a language of choice)

  • What is the best wrapping strategy ?

    - by Riduidel
    Hi, I'm planning to integrate an external tool (ffmpeg in my particular case, but it could be anything, in fact, as lolng as its tasks are long running ones). This tool has a lot of command-line parameters. For now, I've done to simple things with it, already requiring me a good bunch of class writing, to embed all the information it can return to me. I now face the even more complex task of having to send it a bunch of parameters and to handle possible errors. So, what is a best way for that ? Create classes containing all possible options Relying upon a reverse equivalent of commons-cli / CliBuilder / OptionParser Directly write all options from user input Obiwan Kenobi powers (or anything I don't even know about) Please notice I do it in an uncommon language (for the sake of me, don't ask me what it is, as it looks like a desperate and sterile union between CoffeeScript and lua), as a consequence, there can be no framework doing what I want in the language I use.

  • Should vendors have an express queue for people who have a clue? What passes for support today?

    - by Greg Low
    It's good to see some airports that have queues for people that travel frequently and know what they're doing. But I'm left thinking that IT vendors need to have something similar. Bigpond (part of Telstra) in Australia have recently introduced new 42MB/sec modems on their 3G network. It's actually just a pair of 21MB/sec modems linked together but the idea is cute. Around most of the country, they work pretty well. In the middle of the CBD in Melbourne however, at present they just don't work. Having...(read more)

  • Wifi won't work without ethernet (Ubuntu 12.04)

    - by alok
    I have a strange problem. I am running Ubuntu 12.04 on a Dell Studio 1558 laptop. I'm usually unable to access Wifi (I have a BCM43224 wireless card with the STA proprietary driver installed.) So I have to unplug the ethernet cable from my Wifi router and stick it into my laptop's ethernet port to access the Internet. But when I stick the cable back into the Wifi router and try connecting to Wifi, Wifi inexplicably starts working. How can I get Wifi to work all the time without having to 'jumpstart' it with an ethernet connection?

  • Book about tcp, http, named pipe, shared memory, wcf and other inter-process communication protocol

    - by Samuel
    Recently, I had to create a program to send messages between two winforms executable. I used a tool with simple built-in functionalities to prevent having to figure out all the ins and outs of this vast quantity of protocols that exist. But now, I'm ready to learn more about the internals difference between each of theses protocols. I googled a couple of them but it would be greatly appreciate to have a good reference book that gives me a clean idea of how each protocol works and what are the pros and cons in a couple of context. Here is a list of nice protocols that I found: Shared memory TCP List item Named Pipe File Mapping Mailslots MSMQ (Microsoft Queue Solution) WCF I know that all of these protocols are not specific to a language, it would be nice if example could be in .net. Thank you very much.

  • Apps capable of mounting/unmounting CD/DVD Images with multi-sector or protected format

    - by Luis Alvarado
    What apps for Ubuntu exist that can mount/unmount CD/DVD images. Image formats like cue, bin, iso, nero format, etc... Needed features: Emulate protected CD/DVD like Daemon-Tools Mount multi-sector images Converting other formats (including multi-sector images) to ISO format. UPDATE - Updated question to "need the 3 features above instead of having them as optional". This 3 features are needed to be able to use images that have any of this features enable. For normal mounting/burning image apps you can see here: How can I graphically mount ISOs? Can I mount an ISO without administrative privileges? How burn or mount an ISO file?

  • No boot loader found - dual booting Windows 8 with Ubuntu 14.04

    - by Sriram
    I have been trying in vain to dual boot my computer with Windows 8 Pro (pre-installed) and Ubuntu 14.04 64-bit. I have been able to successfully install Ubuntu 14.04, but the option to start Ubuntu does not appear on startup. This is after having taken all steps as mentioned in Installing Ubuntu on a Pre-Installed Windows 8 (64-bit) System (UEFI Supported). I even tried the boot repair option and ended up with this error log. My questions are: How do I solve for No boot loaders found in /dev/...? Are there any other recommendations that will help me solve this? Other points that may be important: Booting into Ubuntu from a live USB shows all Ubuntu partitions on the hard drive.

  • Arabic disappeared after 12.04 upgrade!

    - by Aboubakr
    Well, I was amongst the 12.04 Beta upgraders, and since then I've lost the ability to write in Arabic, and I've been using Ubuntu since 2008 as an only OS without any issues, and been upgrading since then as well, except on this machine, which received one upgrade from 11.10 to 12.04 and it got messed up. I've added Arabic like usual, but it doesn't change with the keyboard's short-cut, and when I do it manually with the Mouse, then it just doesn't work, and it keeps writing in English instead. I've tried to install some iBus things, and added Arabic-kbd (m17n) but it still remains messy, let alone not having the same layout, and all I want is to get to NORMAL. So, please, is there any way to reset or initialize these keyboard related settings, so I can get back to normal and stop using the Mac just to type in Arabic, or so often using XP over Vbox? And please, no Re-install option! I just can't backup all my work right now, and there are a lot of tasks waiting for me to get them done. Thanks for any kind of support :)

  • will Unity have a keyboard shortcut for accessing the "Session Menu" that appears on the panel?

    - by Sam
    I noticed in screen shots of Unity the presence of the "Session Menu" indicator in the right corner of the top-panel. This menu drops down to offer Log Out, Hibernate, Restart, Shut Down, etc. I know the keyboard shortcuts are not complete yet. But are there plans to implement a shortcut for accessing this Session Menu (i.e., so users can log out, restart & shut down without having to use the mouse)? Further, will the shortcut allow navigation through the menu by just typing the first letter of the listed word (e.g., R for restart and S for shut down)?

    I am having problems getting grub to load Windows 8 properly after installing Ubuntu 12.10 and Windows 8 on a solid state drive. Here's what I did: Fresh install of Windows 8 using USB recovery drive (partitioned SSD for UEFI) -- Tested windows install and it worked fine Built bootable USB with Ubuntu 12.10 64bit and installed Ubuntu -- Used Ubuntu's installer to partition the Windows 8 partition and install there Reboot - try to load windows 8 from grub -- Ubuntu loads correctly; windows load reports various problems with permissions and not being able to find files - I'll update what the actual errors are Tried to fix the boot problem using boot-repair: -- here's the output: http://paste.ubuntu.com/1384522/ So, this is my first time trying to setup a dual boot system and I think that UEFI is the main culprit in getting this to work correctly.

The problem with mine is that when I run FAHControl in terminal, it says Error 111 connection refused. This doesnt happen when i run folding at home on windows. Can someone tell me how to fix this? Thanks.

  • How do I tackle top down RPG movement?

    - by WarmWaffles
    I have a game that I am writing in Java. It is a top down RPG and I am trying to handle movement in the world. The world is largely procedural and I am having a difficult time tackling how to handle character movement around the world and render the changes to the screen. I have the world loaded in blocks which contains all the tiles. How do I tackle the character movement? I am stumped and can't figure out where I should go with it. EDIT: Well I was abstract with the issue at hand. Right now I can only think of rigidly sticking everything into a 2D array and saving the block ID and the player offset in the Block or I could just "float" everything and move about between tiles so to speak.
