Apart from the usual Super + Arrow keys to manage windows within a desktop, you can use: <ul> <li>Ctrl + Alt + Left/Right Arrow: Move desktops</li> <li>Ctrl + Alt + Shift + Left/Right Arrow: Move window to desktop</li> <li>Super + Shift + Arrow: Move window to another monitor</li> <li>Super + Drag: Drag window from anywhere</li> </ul> </li> <li><code>jq . file.json</code> is an efficient way to pretty-print JSON files in the terminal. (Or <code>jaq . file.json</code>, which is ~30% faster.)</li> <li>GitHub Copilot monthly premium requests were <em>not</em> reset at 12 am UTC</li> <li><a href="https://social.jvns.ca/@b0rk/116297197345549083">How Diffie Hellman Key Exchange Works</a> by Julia Evans is an <em>excellent</em> explanation. Share a random number. A multiplies it by their private key and shares S<em>A. B multiplies it by their private key and shares S</em>B. They multiply the others&rsquo; key with their secret key and they get S<em>A</em>B = S<em>B</em>A. Now <em>both</em> of them have the same <em>new</em> secret they can encrypt/decrypt with, but no one else knows, even though they shared everything publicly! This may be one of the <strong>best</strong> cool uses of math I&rsquo;ve seen in a long time.</li> <li><a href="https://blog.hofstede.it/shell-tricks-that-actually-make-life-easier-and-save-your-sanity/">Shell tricks</a> I didn&rsquo;t know: <div class="highlight"><pre tabindex="0" class="chroma"><code class="language-bash" data-lang="bash"><span class="line"><span class="cl"><span class="c1"># ALT + . cycles through the last arguments typed</span> </span></span><span class="line"><span class="cl">mv file.<span class="o">{</span>txt,md<span class="o">}</span> <span class="c1"># Move file.txt to file.md</span> </span></span><span class="line"><span class="cl">ls <span class="p">|&amp;</span> tee file.txt <span class="c1"># Pipe both stdout and stderr to tee</span> </span></span></code></pre></div></li> </ul> https://www.s-anand.net/blog/why-linux-does-not-need-defragmenting/ Sun, 10 Sep 2006 12:00:00 +0000 https://www.s-anand.net/blog/why-linux-does-not-need-defragmenting/ <p><a href="http://geekblog.oneandoneis2.org/index.php/2006/08/17/why_doesn_t_linux_need_defragmenting">Why Linux does not need defragmenting</a> (via Google Operating System&rsquo;s article on <a href="http://googlesystem.blogspot.com/2006/09/fast-disk-defragmenters.html">fast disk defragmenters</a>.)</p> https://www.s-anand.net/blog/i-am-debian-linux/ Tue, 13 May 2003 12:00:00 +0000 https://www.s-anand.net/blog/i-am-debian-linux/ <p><a href="http://bbspot.com/News/2003/01/os_quiz.php">I&rsquo;m Debian Linux</a>.
