Reproducibility is a critical feature of science. The chaotic features of nature contribute to artifacts in our measurements, but these errors can be mitigated by taking more measurements ¹. The subsequent trials can reveal the random variation, and hint at the true quantity being sought.

Reproducibility is no guarantee of correctness. It will never indicate if the correct thing is being measured, or if it's even important. It does, however allow for more reliable results in science.

I often have friends recommend me their art pages or creative works that solely exist on the corporate social media websites:

• instagram
• medium
• facebook
• tumblr
• wix

If you care about discoverability and long term viability of your online presence, creating your own website is better in every way.

The common criticism against creating your own website is that it's a lot of work for something that these corporate platforms provide for free. Creating your own website is like buying a house, using corporate social media is like renting. Like house ownership gives you autonomy in your life, owning your own webspace gives you creative freedom.

This summer, I took a course called MSE428: Design of Mechanism. It was a challenging course but in the end I got to build an automaton.

An automaton (ɔːˈtɒmətən; plural: automata or automatons) is a self-operating machine, or a machine or control mechanism designed to automatically follow a predetermined sequence of operations, or respond to predetermined instructions. - wikipedia

For our automaton, we chose to tell the humilating story of losing first place in mario kart to someone that just got the bullet bill item. The shafts and supporting structure was 3d-printed.

Youtube has been tearing apart the sub feed for a couple of years now. Things like: videos not appear in chronological order, terrible general layout, and enhancing difficulty it takes to get to the youtube subfeed¹. In this post, I will be explaining how to make a better youtube sub feed.

I love qutebrowser for its vim keys but I found that qutebrowser's cpu usage was too high. Indeed, the cpu usage reached 80% on my sandy bridge i7 laptop when I had one archwiki tab open. To fix the high cpu usage, I disabled software rendering. Here are the steps I followed:

1. Open qutebrowser
2. Type in :set
3. Look for qt.force_software_rendering and set the option to false
4. Restart qutebrowser

Keep in mind that if you use Nouveau drivers you must have software rendering enabled and this fix will probably not work for you.

Required Readings

• Multicore Programming with NI Labview
• Wait (ms) Function
• High Resolution Relative Seconds VI
• Boolean Crossing PtByPt VI
• Probes

Important Notes

• “Wiring a value of 0 to the milliseconds to wait input forces the current thread to yield control of the CPU.” - See “wait (ms)” in required readings
• Using wait (ms) block causes timing issues.
• Use a global timer
• Avoid using sequences

Note: This patch has been merged with upstream. Simply update your archlinux machine and npt should just work.

The new npt patch allows you to enable npt on ryzen cpus and get native performance in a virtual machine. Please be advised that this patch is not mainline and may cause other problems. As always, make backups.

For this procedure we will be using the Arch Build System so that pacman will manage all of the files and so we can rollback a kernel by looking into /var/cache/pacman/pkg/ and using pacman -U.

I recently installed a matrix (synapse) on the server. It has encryption, high quality image uploads, bots, and all the data is stored on my own server. In order to use the chat service:

1. Message me to make you an account

2. Go to riot

3. Press custom server

   Home server URL: https://momi.ca:8448

   Leave identity server URL as https://vector.im

4. Enter the username and password I gave to you

5. When you join a room with encryption, you will be asked to accept keys. For now, tell everyone that you’re signing in from a new device and tell them to accept the keys.
