-
-<p>A window manager is a software that can manage the layout and appearance
-of every window spawned in your desktop, most people confuse them with
-desktop enviroments, which isn’t the same since a desktop enviroment is
-more of an ecosystem, they come with a more ‘complete’ set of tools,
-like a basic web browser, a terminal emulator or calculator, an example
-of desktop enviroment would be gnome, xfce or kde plasma; instead a
-window manager is only the program that manages the windows spawned,
-although there are window managers that come with a little more, like
-docks or taskbars (openbox for example).</p>
-
-<p>In my case I use dwm, which is a window manager written in C developed
-by suckless software. The most relevant thing of this window manager is
-that out of the box it comes with the most basic functionallity, and if
-you want to extend it you need to patch it.</p>
-
-<p>By default dwm comes with 9 workspaces, in which you can open as many
-windows as you please; to spawn a new window for example a web browser
-you need to assign it a keybinding or use an application launcher like
-<a href="https://tools.suckless.org/dmenu/">dmenu</a></p>
-
-<p><a href="screenshot.png" title="Screenshot of my dwm build"><img src="screenshot.jpeg" alt="Screenshot"/></a></p>
-
-<h2>Installing dwm</h2>
-
-<h3>Requisites</h3>
-
-<ul>
-<li> GNU/Linux or BSD based operating system</li>
-<li> A C library and a C compiler</li>
-<li> make utility installed</li>
-<li> X server installed</li>
-<li> dwm source code, you can clone the repository or download as a tar file at the web</li>
-</ul>
-
-<p>As you can see above you can only install dwm on GNU/Linux or BSD based
-distros, unfortunally dwm is not available for Windows users but I’m
-sure there is an alternative.</p>
-
-<h3>Installation</h3>
-
-<p>In order to install dwm you can visit the web of the creators at
-<a href="https://dwm.suckless.org/">suckless.org/dwm</a>, where you can download
-the source code as a tar file, or clone the repository.</p>
-
-<p>After you obtain the source code you need to navigate to the root folder
-of the source code and execute the following command</p>
-
-<pre><code class="language-console"><span class="pun">$</span> <span class="pln">sudo</span> <span class="kwd">make</span> <span class="pln">install</span>
-</code></pre>
-
-<p>after that you can log out of you user account, if you use a display
-manager you can select dwm as window manager and log back in, if you
-dont use a display manager you need to edit your .xinitrc file located
-at you home folder so that when you start X dwm gets launched too, you
-do this by adding `exec dwm` to the end of the .xinitrc
-file, its important that you add it to the end of the file.</p>
-
-<pre><code class="language-console"><span class="pun">$</span> <span class="pln">cat</span> <span class="pun">$</span><span class="typ">HOME</span><span class="pun">/</span><span class="pun">.</span><span class="pln">xinitrc</span>
-<span class="kwd">exec</span> <span class="pln">dwm</span>
-</code></pre>
-
-<p>Then you can start the X server by executing `startx` on a tty and it
-should open dwm without any problems.</p>
-
-<h2>How do you configure dwm?</h2>
-
-<p>Basically you configure it by editing its source code, inside the root
-folder of the project there is a C header file named
-<a href="https://github.com/klewer-martin/dotfiles/blob/master/.config/dwm/config.def.h">config.def.h</a>
-which if you open with a text editor you can see that there is some C
-code that you can edit, for example the line “static const int topbar”
-defines a variable named topbar which you can set to 1 or 0, to select
-if the status bar should spawn in the top or the bottom of the screen.
-After every change you make to the source code you need to copy
-config.def.h to config.h and then recompile dwm</p>
-
-<h3>Show information on the status bar</h3>
-
-<p>dwm by default won’t show any information on the status bar, this is
-done by using the xsetroot utility, which sets the WM_NAME enviroment
-variable that dwm uses, lets assume you want to set the clock and date
-on the status bar, well you could execute the following command</p>
-
-<pre><code class="language-console"><span class="pun">$</span> <span class="pln">xsetroot</span> <span class="pun">-</span><span class="pln">iname</span> <span class="pun">$</span><span class="pun">(</span><span class="pln">date</span><span class="pun">)</span>
-</code></pre>
-
-<p>and all the output of the command `date` would be printed on the status bar, this
-makes dwm status bar highly scriptable, in fact there are a ton of status
-bar implementations, the one that I use is called
-<a href="https://github.com/torrinfail/dwmblocks">dwmblocks</a> and its also
-written in C and the configuration its pretty much the same as dwm, in
-order to get information you need to have scripts that prints the
-desired data to stdout, then you can include it on the config.h of
-dwmblocks by having them on a folder which is included in the $PATH
-variable of your user.</p>
-
-<h3>Getting emoji support on dwm</h3>
-
-<p>dwm by default doesn’t come with emoji support, if you want to render
-an emoji in the status bar its going to either show it as a box or in
-the worst case crash, so in order to get emoji support first you need to
-get a font with emojis, I’m using <a href="https://www.joypixels.com/">JoyPixels®
-font</a> you can also use
-<a href="https://fonts.google.com/noto">Google’s noto font</a>, or any other font
-that comes with emoji support. Then open dwm configuration file and
-append to the fonts array the name of the font you want,
-in my case it’s JoyPixels®.</p>
-
-<pre><code class="language-c"><span class="kwd">static</span> <span class="kwd">const</span> <span class="kwd">char</span> <span class="pun">*</span><span class="pln">fonts</span><span class="pun">[</span><span class="pun">]</span> <span class="pun">=</span> <span class="pun">{</span> <span class="str">"Source Code Pro:style=Regular:size=9"</span><span class="pun">,</span>
- <span class="str">"JoyPixels:style=Regular:size=8"</span><span class="pun">,</span>
- <span class="str">"DejaVu Sans"</span> <span class="pun">}</span><span class="pun">;</span>
-</code></pre>
-
-<p>After you setup the font you need to remove or comment a chunk of code
-from drw.c, a file located in the root of the folder where dwm source
-code resides, between lines 136-150 there is a function named IsCol, you
-need to remove it or comment it.</p>
-
-<p>Finally you can recompile dwm and you will get emoji support. Sometimes
-even though you made all this procedure you still get boxes insted of
-the proper emoji, I solved this by adding another font name in the
-fonts array, like a fallback font.</p>
-
-<h3>Patches in dwm</h3>
-
-<p>Since dwm is a simple program than doesn’t include much features, if
-you want to extend it, for example by adding a
-<a href="https://dwm.suckless.org/patches/systray/">systray</a> to the status bar,
-you need to patch dwm. To do this first you need to download the patch
-from <a href="https://dwm.suckless.org/patches/">suckless.org/patches</a>, then
-make sure you got it ‘patch’ installed, although I think it comes with
-most linux distributions by default nowdays.</p>
-
-<pre><code class="language-console"><span class="pun">$</span> <span class="pln">patch</span> <span class="pun">-</span><span class="pln">p1</span> <span class="pun"><</span> <span class="pun"><</span><span class="pln">file</span><span class="pun">.</span><span class="pln">diff</span><span class="pun">></span>
-</code></pre>
-
-<p>If you never patched dwm before then probably no errors would be
-reportjd, but if you already have applied a ton of patches then probably
-you would get a HUNK ## FAILED, in this case you need to get your hands
-dirty, and manually patch all the files that failed, you do this by
-opening the files with .rej extension (short for rejected), and the
-corresponding file to be patched, for example dwm.c and dwm.c.rej, and
-then you add all the chunks of code from the rejected file into the
-corresponding place in the non rejected file, you know where you should
-put the chunks of code because in the rej file you can see at the start
-of every chunk there is a ‘@@’ followed by a number of line; also
-lines starting with plus means add, and minus means delete, if I’m not
-clear you should google how to use diff and patch to modify a file.</p>

-
-<p>This will be my second time that I attend to this event since I’ve been there for the first time in 2019. I remember that <a href="https://en.wikipedia.org/wiki/Jon_Hall_(programmer)">John ‘Maddog’ Hall</a> was making a presentation called “50 years of UNIX and the landing on the Moon”, you can find a record of the presentation <a href="https://www.youtube.com/watch?v=9O_FnKZI6_M">here</a>.</p>

-
-<p><img src="sav.gif" alt="" title="Gif showing SAV working"/></p>

-
-<p>The main purpose of this app was to put in practice the knowledge I gained in C as well with algorithms, and it was like a challenge since I’d never used SDL2 graphics before. In the end was a very enjoyable project since SDL2 per se is a very simple and easy to use library.</p>

-<li>bubble sort improved</li>
-<li>insertion sort</li>

-<p>If we think for a moment about software we are going to realize that the
-core of every program is just plain text, literally, just words in a
-file that someone wrote, this webpage it’s just text interpreted by
-your web-browser, whose also just plain text implemented by another
-program, some software has more complexity than others, for example the
-linux kernel it’s estimated that has around 27.8 million lines of code,
-which is also just plain text</p>
-
-<p>The way we tell computers what to do it’s with text, so in order to
-write that text we just need a text editor and this is were Vim it’s
-known for. Vim it’s just a text editor. The term Vim stands for Vi
-IMproved, Vim it’s a rewrite and improved version of Vi, a text editor
-that dates from 1978.</p>
-
-<p>In this article I want to show how this text editor became my best
-frient (?), I learned to love about Vim keybindings and now I even have
-and extension on my browser to use vim like keybindings.</p>
-
-<p>Vim is a console text editor (altough you can find distributions like
-gvim, which comes with a gui), a benefit of this its that It’s very
-lightweign in terms of system resources. Vim it’s also highly
-configurable, you can do this by editing the <em>.vimrc</em> text
-file, which should be in you home directory in Linux or BSD bases OSs,
-if not you can <em>create</em> a new blank one and start from zero</p>
-
-<p>If you installed Vim and you don’t know how to move around or insert
-text, first you need to understand the basics, Vim has 3 main “modes”</p>
