I wrote a test app that scans for plugins in a directory, calls their getWidget() method (implemented in my interface), and adds that widget to a layout.
The problem is that when I added a QTimer to my plugin class, it didn't work! Why?
And will it be easier to write the thing in Python and not use QPlugin? I just want to define a QWidget and have it added to the app.
I wanted to make some modifications to a Kate plugin, so I cloned the git repository, started doing a few changes, and it compiled. The problem is that when I run it, it uses the version of the plugin installed in the system, not the one compiled with Kate.

I have an interdependent collection of scripts in my ~/bin directory as well as a developed ~/.vim directory and some other libraries and such in other subdirectories. I've been versioning all of this using git, and have realized that it would be potentially very easy and useful to do development and testing of new and existing scripts, vim plugins, etc. using a cloned repo, and then pull the working code into my actual home directory with a merge.
The easiest way to do this would seem to be to just change & export $HOME, eg
cd ~/testing; git clone ~ home
export HOME=~/testing/home
cd ~
screen -S testing-home
# start vim, write/revise plugins, edit scripts, etc.
# test revisions
However since I've never tried this before I'm concerned that some programs, environment variables, etc., may end up using my actual home directory instead of the exported one. Is this a viable strategy? Are there just a few outliers that I should be careful about?
Trying to watch videos for the first time using Fedora 13 there was just a black screen where the video play button should be, both on Firefox and Google Chrome, and the message: ?You need to upgrade your Adobe Flash Player to watch this video?. So I downloaded Flash Player 10.0 for x86_64 from Adobe Labs. They advised: To install it, copy libflashplayer.so to your 64 bit browser plugins directory (such as /usr/lib64/browser-plugins/). How do I do this? I know how to sign in as root, but don?t know how to go to /usr/lib64/browser-plugins/, nor do I know how to ?copy libflashplayer.so to your 64 bit browser plugins directory?

I am trying to use a shell script to find a string in a file and do something when found. code...
What should happen is pppd will start in a different process and stream it's output to pppdout. pppdout should be created in the current folder. Then the script should periodically check the pppdout file for the string Script (which eventually will appear, some seconds later) and when found exit the script. Ultimately the script will do something useful when the text is found. However, the output from the program is a repeating: 'scriptname.sh: 12: FOUND: not found'
Where scriptname.sh would be the name of your script and 12 refers to the line with 'done'.
Why does grep not find the text, or at least why deos my script not check the grep output correctly?

View 2 Replies View RelatedI started to run a C++ my program in Linux and I don't know how to test my program that works fine with a text file. This is a project for my uni and to explain more clear, My program is a sample database for modify or add and search and it read data from a binary file and also write into a binary file. I have got an input from my lecture and she said after compiling in Linux I must write:
1-to compile:
Code:
g++ (files with cpp)
2-to see the output:
Code:
./a.out
3-to test with input:
Code:
./a.out < input.txt >
My problem is in step three. What I must write in the command part after" step2" to see the output?
I ran a perl script in background with nohup and disown to make sure my script runs even after the parent process is terminated.
Method 1: nohup
> nohup perl run.pl &
[1] 2080
Method 2: disown
> perl run.pl &
[2] 2448
> disown
In either method, the script process doesn't seem to connect to init process, when I checked using pstree command. I thought, the disown or nohup command detaches the process from its parent and attaches it to grand grand parent init process. And it disables SIGHUP signal to my script process. But the pstree command didn't show me what I expected. It still shows my script process attached to my current terminal process. I just don't understand the concept behind these two commands (nohup and disown). Is there any way, I can see the list of processes that are run by nohup or disown command?

I am exploring the Python 3 standard library and am currently attempting to test the bin function. It converts an integer into a binary string. I believe the module I wrote is flawed somehow. Here's the source code:
Code:
#!/usr/bin/python3.1
#This module tests the bin() function.
import sys
def get_input():
x = input("Enter an integer: ")
def use_bin():
[code]....
As you can see, the binary form given is always 0b10111. I'm no expert on binary code (or hexadecimal notation), but surely 9000 and two would have different results?
EDIT: Added a line in the module to repeat back what integer the user entered, and then the binary form. It would appear that no matter what integer the user enters, Python thinks it's "23".
Example output:
Code:
>>>
Enter an integer: 1
You entered 23
The binary form of this integer is 0b10111
>>>
I'm writing a code to get the index of the last occurrence of a given substring in a string.
Code:
int StringHandler::lastIndexOf(string src, const string s) {
unsigned int lastIndex = string::npos;
if (src.find(s, 0) == string::npos) {
return -1; } else {
bool isLast = false; unsigned int i = 0; do {
lastIndex = src.find(s, i);
if (lastIndex != string::npos) { i = lastIndex + 1;
if (i == src.size()) { isLast = true;
} } else { isLast = true;
} } while (!isLast);
} return lastIndex;
}
My problem is: execution steps into an if with a false condition! Check the values of i and src.size() at the right panel. How could be possible for the program to run the highlighted statement? The if condition above is false! [URL]. I could use char arrays, for example, but this kind of false validation has happened to me more than once, I'm using G++ 4.5 with these flags: -O0 -g -Wall -c

Few 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 ?
I was windering, if you are writing a C program, I don't think you are supposed to commit the .o files and executables. How can you test your program without making a copy outside the git working dir?
