Mar 10, 2010I am very new to Linux and I hope someone on here can provide some help.
Goal:
I am am developing an embedded application on Linux 2.6 that will hopefully run without a GUI. There will be no user input just simply displaying information to the user in a graphical form. I will be drawing the screen in C and outputting this to the display.
Problem:
I don't know how to draw to the display? From reading and talking with others, I think I can write to the frame buffer and that will output to the display, but I am not sure this is rite. If it is correct, can someone explain how this is done? Is there another way to draw to the screen without using the windows API?

Ubuntu :: Getting The Circle Dock Equivalent?
Feb 12, 2011Circle Dock which is(in my opinion)a very cool Open source application which is essentially a circular, Oval, spiral dock for windows which is implemented in .Net using C#. Ever since I got to use it on windows I have been desperate to find an equivalent for Linux-The closest thing I have found is Circular application menu which is very different. I was wondering if anyone knew of something like circle dock that runs on linux?

View 2 Replies View RelatedProgramming :: Get Started With Making 'a SIMPLE Dock'?
Mar 22, 2011This is probably hopelessly ambitious as I'm not a C or C++ programmer (I normally like to stick to scripting languages like BASH or Perl). Basically I'm looking on good advice to get me started with writing a Application Dock with the functionality of the OSX dock but without the overly flamboyant graphics that have characterised the Linux versions.At the moment the closest I've found to what I would like is bbdock. However it falls well short of the functionality of what I would like.
What bbdock does is read a file to create an icon for the openbox dock/fluxbox slit/wmaker whatever that launches an application when first clicked, shows an little arrow when the application is running, and brings the application to the fore when clicked once running.Here's a screenshot of it doing just that.The drawback to bbdock is that it doesn't really look for running applications, only those launched from bbdock. So for example it wont notice if I've launched an instance of pcmanfm from the openbox menu. And therefore it obviously also doesn't add icons for other applications that are running.
What I would like to be able to do is detect new running applications and add a bbdock icon for them. Also to detect if an application already with a shortcut has been run and update it's status to show it's open. Probably have an up and down arrow to move the icons up and down when there are too many to fit on the screen. None of the above needs fancy animation. The fade to gray effect used by bbdock is quite nice and could probably be augmented with a fade in and out to grey to represent another action, say fading to grey and back when launching and greyed when iconified.So, my question is what do I need to get started doing this? Am I best using the pretty outdated bbdock wmaker dockapp style? What functions and libraries am I likely to need to achieve the effects I want? Are there any examples of how to monitor running applications (well windows and figure out what constitutes a new application) that I could look at for inspiration. Is there anyone who's into C++ for linux who would be interested in helping me out to get this small project working?

Programming :: Making Existing MS Excel App Web Based
Jun 7, 2010I have a LAMP based web hosting account (BlueHost). I have an existing simple MS Excel application which I would like to make it web based. However I am not sure what tools or features of PHP are out there that will aid me with this task. Here are some details:
1. I don't want to create an entire Excel program online. For that there are plenty of existing applications like Google Docs, MS's own online version of Excel, etc.
2. My current excel file uses some of the following excel functions:
a) SUM
b) Product Sum
c) Conditional Formatting (like changing font color if an amount is below a threshold, etc.)
d) Sorting (Date, Amount)
e) Drop Down Box to select pre-defined values
3. Ability to add/delete/modify a entry (row)
4. I don't care whether the application has the same look-n-feel as MS Excel.
As you can see it is a very simple home grown excel application with few basic mathematical functions. Here are some few thoughts that I have currently in my mind:
i) Just start coding intuitively as you would develop a normal web based application.
ii) Do (i) but use some of the PHP's excel oriented helper functions (COMs?) if there are any
iii) Use completely a different set of tools permitting that they run on LAMP environment.
I could have started with (i) but before making a costly mistake I thought I would get some opinion from the community to see if this is the right approach.

Jun 25, 2010I'm trying to make my first c project (a simple tic tac toe console game), and I am wondering how to make a final product (copy all source code files to a distribution folder upon compilation). Should I use a bash script or should I use a makefile to make the distribution folder? I'm not terrible familiar with either; I have a basic makefile to make an executable, and that's about all I know of make.
And if I do use a bash script, how do I copy over source code files? I tried cp ./*.c and cp ./*.h, but I think the script read it literally as moving a file named ./*.c (and ./*.h), and couldn't find it.
My makefile is pretty much this:
Code:
objectFiles = main.o io.o board.o game.o
ttt : $(objectFiles)
cc -o ttt $(objectFiles)

Programming :: RHES 5 - Making Sed Snippet To Be Portable
Jul 27, 2011I have an odd issue that I am running into. My objective is to insert the following lines at the end of /etc/inputrc on an RHES box:
Code:
# alternate mappings for "page up" and "page down" to search the history
"e[5~": history-search-backward
"e[6~": history-search-forward
I would like this sed snippet to be portable and thus far it's worked. However, I ran into one box where after I ran the snippet, Subsequent sessions lost the ability to use the letter "e". The original version I was using looked like this:
Code:
mv /etc/inputrc /tmp/inputrc.orig
sed 's/'$endif'/
# alternate mappings for "page up" and "page down" to search the history
"e[5~": history-search-backward
"e[6~": history-search-forward
&/' /tmp/inputrc.orig > /etc/inputrc
Then instead of using s/ I thought perhaps i/ would be better so I re-did it as:
Code:
mv /etc/inputrc /tmp/inputrc.orig
sed '/'$endif'/ {
i
i
# alternate mappings for "page up" and "page down" to search the history
i
"e[5~": history-search-backward
i
"e[6~": history-search-forward
}' /tmp/inputrc.orig > /etc/inputrc
Both of these produce the expected result BUT they both resulted in the loss of the letter "e". As I mentioned earlier in the post, this was working on 'newer' RHES 5 and up but I have the misfortune of having to support some older RHES 4 boxes in a closed lab. This particular box is an RHES 4u6.

Dec 11, 2010I need to write a shell script that will be run from cron every minute or so. The script will use rsync to keep some folders across several machines in sync. I am very new to shell scripting so some answers might seem obvious but they are not to me:
1. How do I check at the beginning of the script if the script is already running and abort if it is? I saw that most processes use a PID file for that but I am not sure this is the right case for that and in fact how to do it exactly
2. Assuming the list of target machines/dirs to sync are supposed to come from some config file. How should I code that? Just use the normal shell tools that I already know (cut etc) or is there a better way?
Programming :: Do Not Miss Any Cases While Making The Test Case Doc?
Jul 28, 2010Few months back I learnt a *few* concepts about bits/bytes and started writing a program for bit packing in C++. Now that program has grown upto 600 lines and I am still working on it. Yesterday I realized I missed some special cases due to which the program was malfunctioning. Now I have modified the program and it is working properly but I think If I would have designed all the possible test cases before writing the code, I would have finished the program long ago.
I. What is proper way to design the test cases before coding?
II. How should I make sure that I do not miss any cases while making the test case doc. ?
III. Does writing test cases prior to coding solve messy code issues or should I consider something else ?
