<h2>Keyboard Navigation Enhancement</h2>
<p>
Switching between typing and navigating is time-consuming, since typing
requires both hands to be on the keyboard, while navigating requires the
right hand to be either on the arrow keys or the mouse. This is especially
worse for laptop users.
</p>
<p>
To reduce the need of switching, I produced a series of scripts that allows
the keyboard to be used as a mouse and a number pad. My work is hosted on
GitHub here:

<h2>Filament Dry Box</h2>
<div class="fig">
<img
src="Images/others-dry_box.jpg"
alt="Image of my filament dry box">
DIY filament dry box containing lightweight PLA, PETG, TPU, and PLA+.
</div>
<p>
Since I print with PETG and sometimes with TPU, and since my room has a
humidifier, I decided to create a DIY passive filament dry box, so that the
filaments can be quickly changed.
</p>
<p>
This dry box was made using an 18L waterproof box with a PVC pipe as the
spool holder. Nuts and bolts held the 3D printed pipe holder in place, and
PTFE tube with coupler was used to reduce moisture going into the box.
Silica gel packets were placed inside as a passive dryer.
</p>
<h2>Take Back Your Control: Android</h2>
<p>
If you use Android, it likely comes with bloatware --- pre-installed apps
that you do not use nor need. Worse, there are applications running in the
background that constantly degrade battery life --- in particular, almost
all of Google services. Worst, the Android that you paid for will not be
supported nor last as much as you may want it to.
</p>
<p>
In search for making my cellphone battery last longer hours, and the phone
itself to last more years, I began the journey of 'De-Googling' my phone.
This does not mean removing all Google components. To me, it means utilizing
as little closed-source and power-hungry applications as possible, which
apps made by big tech tend to be. My process was as follows:
<ol>
<li> Switching to an open-source OS that does not contain bloatware and
major Google backends by default.
<li> Utilizing open-source or minimal applications.
<li> Regaining ability to use Google applications.
</ol>
<a href="https://divestos.org/misc/e.txt">Here</a> is a comparison of some
of the major open-source OS that does not have tracking, and is Google free.
If you use a Pixel device, it is best to use <a
href="https://grapheneos.org/">GrapheneOS</a>. Otherwise, <a
href="https://doc.e.foundation/devices">\/e\/</a> is an option that is ready
to use upon installations. I personally use <a
href="https://lineage.microg.org/">LineageOS for MicroG</a> since it allows
me to utilize some required Google Apps.
</p>
<p>
The very first installation is expected to be the hardest. The process
should be the same regardless of what Android you use:
<ol>
<li>
Backup all files: the easiest method is to directly connect your phone
to your computer, and copy all files that you have. I additionally
recommend going to each app and exporting any configurations that you
may have (e.g. contacts, text messages, authenticator codes, etc.). I
also recommend having a list of a list of apps you realistically use so
that you can re-download them later.
</li>
<li>
Unlocking the bootloader: There are several existing online tutorials
for unlocking the bootloader. <a href="https://youtu.be/ksbRMo00uTA">
Here </a> is an example; despite being over 6 years old, the
methodology is applicable today. You can use the <a
href="https://developer.android.com/tools/releases/platform-tools">
developer's page </a> to download platform tools which will be
needed as you follow along any bootloader unlock video.
</li>
<li>
Once unlocked, you can follow <a
href="https://wiki.lineageos.org/devices/">your specific device's
instructions on how to install LineageOS </a>. However, if you want
LineageOS <em>for MicroG</em>, which allows better 'De-Googling' while
still being able to use Google applications, you should use the image
file (.iso file) from <a href="https://download.lineage.microg.org/">
MicroG's website </a> instead of Lineage's .iso file. You will not have
to install any additional files using this method.
</li>
<li>
After completing the reboot, check out F-Droid and all the interesting
things LineageOS for MicroG comes with! You will find many better and
ad-free alternatives to certain applications you used to use. Or you can
use your backup to regain all your past files and re-download your past
apps through Aurora Store (which can be downloaded through F-Droid).
</li>
</ol>
It is possible to go even further and root your phone with <a
href="https://topjohnwu.github.io/Magisk/install.html">Magisk</a> which
allows even greater customization such as significantly <a
href="https://www.celsoazevedo.com/files/android/google-camera/">improved
camera quality</a>, <a
href="https://github.com/di72nn/callrecorder-axet">access to call
recording</a>, and <a
href="https://github.com/MatteCarra/AccA">controlling how much your
phone charges</a> (e.g., to increase longevity of your battery).
</p>
<p>
