Revision 2. </p> <p>Tail multiple pidgin IRC logfiles. </p> <p>Pidgin should be connected to IRC with the channels one wants to tail joined, and it should save logs as text.</p> <p>The script needs two arguments:</p> <pre class="prettyprint"><code>the directory containing the directories with channel logs a list of channel names, quoted and separated by spaces </code></pre> <p>Example command:</p> <p>python pidgin-irctail.py -d <a href="mailto:~/.purple/logs/irc/YOUR_IRC_HANDLE@irc.freenode.net">~/.purple/logs/irc/YOUR_IRC_HANDLE@irc.freenode.net</a> -c "#chan1 #chan2 #chan3"</p> <p>Some text elements are higlighted, and channel names are inserted into the log lines after the time info.</p> <p>If more than one channel is entered, the output of the logs is merged. </p>

<p style="color: grey"> Python recipe 578966 by <a href="/recipes/users/4191156/">Matteo Bertini</a> (<a href="/recipes/tags/threads/">threads</a>). </p> <p>Sometimes it is necessary to ensure that only one instance of application is running. This quite simple solution uses mutex to achieve this, and will run only on Windows platform.</p>

Revision 2. </p> <p>The following class implements a reader-writer lock to use in the second readers-writers problem with python threads. In this problem, many readers can simultaneously access a share, and a writer has an exclusive access to this share. Additionally, the following constraints should be met: 1) no reader should be kept waiting if the share is currently opened for reading unless a writer is also waiting for the share, 2) no writer should be kept waiting for the share longer than absolutely necessary.</p>

<p style="color: grey"> Python recipe 577926 by <a href="/recipes/users/4179733/">Petr Zizka</a> (<a href="/recipes/tags/threads/">threads</a>). </p> <p>Progress bars are popular when trying to show how much of a job has been completed. In my case, it was encrypting and decrypting files. A GUI interface was written, but something was lacking. How was the user of the program supposed to know if the program was doing its job? A progress bar seemed like a good answer, so a simple GUI progress bar was written using Tkinter.</p>
