I've recently been finding myself writing more SQL, on Windows with MSSQL and LinqPad and while I want to experiment on Ubuntu to get more of a handle on databases and I have no love lost for MSSQL, I'll be using MySQL I do want to find a LinqPad equivalent.
What I mean by this in more concrete terms is not the most powerful tool but more of a scratch-pad like LinqPad is, where a novice can quickly write down a query and run it to see what happens, also something which is fast to start and run.
Sorry, this is such a beginner question, but I've recently begun programming with C++ on Ubuntu 12.10 and I've installed a few libraries I need to work with, for example PCL and I can't find them to add them to my project. I'm using Qt Creator as the IDE and qmake which comes with it.
For example, with PCL, I followed the instructions on their site:
sudo add-apt-repository ppa:v-launchpad-jochen-sprickerhof-de/pcl
sudo apt-get update
sudo apt-get install libpcl-all
And as no problems occurred I have to assume they are correctly installed.
Most of the tutorials dealing with adding external libraries I've found on the web assume you're on Windows and know where you downloaded the library.
Since I don't have experience with adding external libraries in C++, could someone please tell me in what file, if there is one, are libraries installed by default in Ubuntu?
What is the extension of these library files?
Is there a script/command which can help detect a library or all the libraries installed?
I'll be honest I've run both OpenOffice and Libre Office and I'm not impressed with their speed/resource consumption both of them lag on my laptop and I don't think it's because of my hardware, for example Kile a Latex development environment based on Kate runs better although it's doing, I think more stuff in the background.
So is there another office suite/ word processor for a Kubuntu 12.10 installation, going with Kate seems too low end while doing everything in Kile is bringing in the big guns to early.
I am mainly interested in speed and of course saving in a reasonably used format, not in having a lot of bells and whistles.
Hello I'm running Kubuntu 12.04 and I've installed Inkscape because I need to edit a .cdr file, Inkscape works like normal but the sole task I need it to do is edit said .cdr file which I understand it should be capable off by default.
Whenever I try to open the file though I get the following error:
UniConvertor failed:
The eror itself is longer but what it seems to be saying that it can't find this application, and I myself haven't found it in the package manager.
If someone has experienced something similar or has a simple solution for editing cdr's I'm no artist I just need to change some names, I would be very gratefull.
Hello I'm running a brand new Kubuntu 12.04 single boot on my laptop, this is the first time I tried connecting to a wireless network.
I tried using the network manager app allready on the task bar, but it doesn't let me tick the column to search for wireless networks, i.e. it will untick it automaticaly, it's dissabled by the software or the hardware, but I doubt it.
I've tried searching the other questions on this site, and I can't see anything which helps with my problem.
I know my wireless card is a Atheros AR9285, I don't think I installed any firmware for it, I'm sorry I can't offer more info but I'm completely new to networking and all that I have for the network to connect to are it's name and password of course.
I have a HP 630 with an i3 processor on which I run Windows 7 64 bit without any problems, I also dual booted Ubuntu 10.04 32 bit I believe, now I upgraded to 11.10 and the clean install doesn't have any apparent problems.
But first thing I update, my Ubuntu won't start it just goes into the purple screen, or more rarely a black screen with a blinking cursor, where it stays indefenetly. The only clue I could find was that when I entered recovery mode the last instruction which appeared on screen before it friezed was:
Booting Node 0,Processors #1
After I tried to install the 32 bit version of Ubuntu 11.10 from a USB stick It froze at exactly the same instruction and wouldn't let me install.
So it's a dual core problem, and maybe a BIOS problem, because it seems that it doesn't want to pass from one processor to another, I added to the grub command line maxcpus=1 and it worked but I don't think it's healthy and it looks like hell.
What is the problem and how do I fix it?
Hello I am running Ubuntu 10.04 and learning the ROS (Robot Operating System) which means that I enter quite a lot of shell commands
I am currently creating some BASH script files to make my work easier, but there are certain commands which must be run in another console.
So please tell me what commands I must write in my .sh file so that it can run it's commands in one window,then start another window in which it run other commands, but from the same .sh file
Or they could be in different .sh files they just need to run in different consoles.

I am have installed Ubuntu 10.04 right now, and I am getting quite a bit of code examples from my browser, Firefox, where the usual ctrl-c short cut works but it doesn't seem to work for pasting the code directly, ctrl-v, into the shell console.
This isn't a critical issue,pasting with the mouse still works,but any suggestions as to how to activate ctrl-v or what the correct native short-cut for the console is would be great.
Hello I've recently installed Ubuntu 10.04 and entered a wrong password for my apartment's wireless network.
Upon entering the network options to edit the password it will allow me to delete it and rewrite but not to save,the save edit button disappears.
I have already tried deleting and recreating the connection but it starts up with the incorrect password already in,also restarting both my wirelesses and laptop have failed.
I feel I'm forgetting some permissions or something and that I should be able to change it from the terminal.
I will accept any solutions but please don't suggest upgrade to the newest edition there's a reason I'm running the old one.
