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 sounds interesting, thanks for info! I decided to stick with octave for my next project, but Julia looks like something worth learning.
@zpartacoos
Yeah, would be nice. I think I'll opt for Octave for now since it's a decent replacement for matlab. And my love for c/c++ is mostly irrational because it's the first language I learned and keep using to this day.
@zpartacoos
It is true, but I'm more interested in native features, to be honest. Also, lack of semicolons triggers me :D
Plus for every package there is a syntax to learn, which kinda makes it troublesome. I am considering Julia, as @nic@nwerneck pointed out, it is an option. I might go full out nerdiness and code in pure c/c++, though...

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.

Matlab is fast enough for the most part, to be honest... Are there good nonlinear optimization libraries for julia? I remember trying like 1.0 version, wasn't exactly smooth.
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?

@zpartacoos
I do. Or rather I did, as for the previous protest from the 23rd of January. For this one both parties, protesters and authorities, have prepared thoroughly, both had a week. I am concerned about possible bloodbath. Civil war is rarely a good idea.
Note: I support them, but I don't attend them. There are reasons for it.

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.

Yeah, this is just what was on top of my head at that moment.

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.
@FailForward
I probably would say something similar about the platform.

# 3 weeks of Mastodon@QOTO
So it's 3 weeks since I joined Mastodon@QOTO. My motivation was a low threshold scrapbook place were I can throw whatever I want to remember and/or share with friends.
After these couple of weeks, I can say this:
* works - kind of. Feels a bit weird, probably because I never did this kind of stuff in public before
* obviously what I am doing is not very standard (more than 200 chars), but within the design envelope of Mastodon and QOTO (kudos for all the customisations, I like it!)
* probably what I am doing would be better called mini-blogging (more than Twitter, less than a blog). When called this way, I took a look at services which do that (e.g., Tumblr) and the usage pattern fits
* timelines are somewhat distracting, but I'll try to use this in a somewhat introvert mode anyway
* interactions are not a bad part of the experience, but need to be managed - can be easily distracting
* lots of strange stuff fly around, but can be filtered out when needed
* the images people post are a throwback into 90's when we were sending this via e-mail (I still have a couple of GBs in my mailbox archive just funny pics and powerpoint slidedecks full of one-off jokes). Since I left this subculture, I never thought it still clogs the Intertubes elsewhere. Still fun, but I could do without.
* tooling: Tusky proved useful, `toot` is good too, web interface a bit overwhelming and distracting
* still need to work out how to deal with hashtags - probably will ignore

This makes sense since for some people (most, as far as I'm aware) trains are a very soothing experience, even if the ride is fairly long. You get a small, cozy space, no internet connection for the most part and either silence and solitude or a fellow traveler whom you can talk to freely, because odds of meeting them again after the ride is over are negligible.

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.

@trinsec @stevax@mastodon.neoziggurat.com
I guess Stevax misread it. My point is that anyone can get a shot, even if your health isn't fine (no one checks your record), while the trial's third phase will only be finished in May. And people apparently are brainwashed enough to enthusiastically book for vaccination.
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.
