Oh well, I finally managed to finish my xmonad config. It is now fully usable. Turns out, it's possible to control sound from haskell without any additional tricks. Neat.
Tiling WMs are my sinful love < 3
I will, of course, spend some time ricing it properly, but this will work for most things. Also, yes, this is xmonad config on pop os instead of the usual arch. Because I'm too lazy to reinstall linux on laptop - there is a plethora of apps and packages and I don't want to deal with this now.

I am slowly getting back to my normal schedule, since uni starts on the 8th in February and it seems like we'll have offline classes. Which sucks, because I'll have to commute up to two hours daily in underground during rush hour. The number of new cases is still quite high in Moscow, so it's concerning. Also, social media in Russia now have to delete everything that contains swearing and a list of things including "encouraging unlawful behaviour" and "irrespecting the government", yes, it is the citation.

For my fellow matlab users out there: minimization produces two different results with the same equation, when different units of measurment are used. Which kinda sucks, because I now need to make ugly convertation patches to see if the code even works properly.

Now, while I'm writing this, optimization code is running in the background. I'll need to finish the calculation this week, ideally today, and submit article draft by the 9th of February. Hopefully I'll manage to pull this off.
Yesterday I have more or less finished my xmonad desktop on laptop. It's now mostly functional, except for sound, but I'll fix it soon. Then I'll hopefully be able to tweak config to my liking and upload it somewhere. Maybe I should after all build a website.

This month I am trying analog bullet journaling as opposed to last year's heavily digital planning. It works surprisingly well for me, I've been posting here consistently for a while, and other habits I am trying to build seem to work better, too. We'll see how it holds once the semester starts, of course.
The most important benefit has been the fact that I detach from my screens (PC, laptop, phone) more often, both to plan and/or journal and for other things too. Slowly breaking an addiction, one could say, although there is a long way to come.
Also, a screw has just fallen out of my chair. Gotta fix it before It breaks apart.

I am going through the process of creating my first video on youtube. This will probably be a series about thermodynamic modelling, which is a subject I am interested in. The question is: should I make it in matlab (which is easier for me and very fast) or in python (which is way too slow for anything serious but which more people know)? People of QOTO, what are your thoughts on the subject?

I am now on the train, going home from countryhouse. It's snowing outside, the view is great for once. On the subject of views - it's amazing how ugly winter gets in the city, snow of the road turns into slit and snow off the road turns gray and black. Most of the time winter in the city leaves nothing but disgust and piles of trash after the snow is molten.
Looks ike tomorrow there will be more protests in the city centre. A few metro stations will be blocked officially, in advance, and god knows what will happen. This wont be peaceful, I'm afraid. Probably should stay away from the center.

I can't have my cup of coffee early in the morning because my sister is still asleep and the grinder is very loud. Oh well, I probably shouldn't whine about it. Coffee can wait.
What amazes me in the modern society is how people point out the problemn and expect it to solve itself somehow. So there was a viral tiktok recently about how google knows everything about you. Seemingly, there is not much to talk about - yes, it does, if you don't like it - degoogle, spend a weekend hosting a mailserver, nextcloud instance, switch your browser to brave (since mozilla isn't really an option anymore) with duckduckgo or other as a primary search engine. Yes, there is also your phone, but there are ways to partially de-google it. You don't even have to invent the solution, it exists. Not enough for you? Install linux, get a librem (or try to boot your phone with free OS), and stop hyping the non-existent problem.

I am a programmer and a scientist, and my work as such mostly consists of fighting with frustration. And this is a surprisingly accurate description for everythiog that involves building things, especially for ones with fixed variables, like experiment results or required features for code. No matter how much you yell at the screen, the numbers won't change, and it's your job to build a somewhat decent model to approximate them, or rather use the existing model and tweak statictical weights until it works well enough.
Apart from beung frustrated most of the time, the experience of getting it right after numerous iterations is worth it.

I am currently on the train, going to meet my gf on the railway. Had little (or rather not enough) sleep but it's okay. Realized what is this that I want to do as a hobby yesterday. Challenging endeavor, but not impossible. Stay tuned for news on that.
Also, I sometimes forget how big my country is. It took my girlfriend 17 hours on train to return here and it's not that far for this place.

Just to clarify - I am NOT an anti-vaccine person. I know that vaccines are necessary and useful. My main concern is the lack of data and the massive propaganda around the subject. Actually, this includes a bunch of bloggers posting themselves getting a vaccine. Be sensible, consult your doctor, read up, do a research and then maybe, if the risks are low enough, take a vaccine. It is an important thing to do but it's not a "no-brainer". Nothing is.

No coffee today since I'll need to do a blood test.
I am deeply concerned about the situation with COVID19 vaccine in my country. One of them is being used countrywide already, and this is an adenovirus-based vaccine. Some pharmacy companies has interrupted their trials of adenovirus based vaccines because of the side effects like polyneuropathy or cardyomyopathy.
But these are commercial companies that are interested in their own well-being. If they cell a vaccine and it kills or injures people, they will suffer consequences. Now, sputnik is a vaccine that is pushed a lot by the government that has a very long story of avoiding consequences of it's actions and ignoring the harm it caused.
So, today I'm doing this blood test to see if I even can take the vaccine because I am allergic to some things. And when the time comes I'd like to make an informed choice about which caccine to use and when.

Today I was doing a bunch of C++ programming and fixing linker issues caused by my ignorance and lack of attention to details. The thing I want to share is a stream I randomly stumbled across, from George Hotz/GeoHot (link below), which starts with casual computer architecture axplanation and proceeds to deconstruct a bunch of things from software engineer's and scientist's perspective. I rarely see things like getting a girlfriend or, say, earning $1m deconstructed using input-model-output approach, although it is a very good way to think about some things. I hope this is helpful.

Well, today I'm writing in the afternoon, since the morning was preoccupied with some work. Yesterday's events in Moscow led my thoughts to an interesting conclusion: convenience usually leads to cavpivity. Here in Moscow the majority of transportation (some trains, subway, buses and trams) works with so called "troika" cards which you can top up. Each card is unique and they are usually bought and topped up using your card. So you are identified by these cards; more so, if you choose to buy a ticket, it is also identified with a number and there are more than enough cameras to identify you. But they can't store this footage indefenitely, right? But these tickets expire very soon,m my guess - as soon as the data is purged, a few months I believe.
Actually, think China, these guys dont need to use tickets! Facial recognition and virtual wallet tied to your ID. Oh, how convenient, right?

2021-01-23, 17:51, Moscow: protests are still going on, I really hope the city center won't get too ruined. Approx. 1.5k arrested, according to unofficial sources. I hope no bodies hit the floor today, but in reality it's very unlikely.

This is supposed to be phi over lambda: \( \frac{\phi}{\lambda} \)
This is e=mc^2: \( e=mc^2 \)
And now with []:
This is supposed to be phi over lambda: \[ \frac{\phi}{\lambda} \]
This is e=mc^2: \[ e=mc^2 \]

@freemo, looks like I broke something...

Good morning.

So I happen to live in Moscow. Today there will be some protests for an opposition politic, he is arrested for no reason other than being, well, in opposition. It seems to be his hobby. On a serious note though, there is one leader in this country and one opposing group. No political variety, you can choose whether your group wins or loses the fight waaay ahead. It's obvious who loses.

Also, I want to test qoto's inline latex.
Which I did and it breaks every time. Sad.

Good morning.

2021-01-21, 08:22, Thursday. Drinking my morning coffee (cezve with some cinnamon) and preparing for my report. I'll probably make a separate post about it since it's an opportunity to tell about my scientific research. For now I'm in a mood to write some more "tips".

STEM tips №2: build your foundation. There is a very good reason for all textbooks on the same subject to convey material in the same order. It is not tradition, it is crucial for understanding concepts. The only exception in basic sciences I am familiar with is organic chemistry: Clayden's textbook is wildly diffirent from standart approach, but I'm not sure how it feels to actually use it for studying without prior knowledge of organic chemistry.

I digress. The particular order most textbooks follow builds new concepts on top of previous ones, and this principle applies throughout your academic career. Let's say you skipped a trigonometry introduction in high school. You crammed for the test and did fine, memorizing all your pi-over-2/3/4/6, but there is no solid understanding of the concept. Now you will struggle in your further math classes. Not only that, in mechanics knowledge of trigonometry is implied, the same applies for calculus, most of the physics and a bunch of other disciplines.

So the takeaway is: don't skip basic topics and make sure you know them very well. Otherwise your ignorance will backfire, usually sooner than later.

Good morning.

2021-01-22, 08:20, Friday. Plain black coffee with very high ratio, almost 10:1. I like it, though.

Yesterday I finished my fifth semester with science work report. Might as well write about my work here. So there are a lot of thermodynamic models of liquids. Modern ones are quite precise, but complicated and have a lot of maths involved. They are very useful to predict the reaction equilibrium or solution's properties, but because of their complexity you need to run them through computer. So people tend to create their own implementations of these models and use them, but diffirent implementations perform calculations slightly diffirently and this can affect results of the study.
The idea is to create a more or less versatile program with GUI, that would be easy to use by anyone and make results reproducible. I now managed to make a prototype with saving, loading and calculating quilibria. The core code of implementation is not mine, however, I use pre-coded model (my colleague made it) to create GUI and more or less intuitive logic around it. The entire thing is in C/C++ and runs quite smootly on binary systems.
