Highload saga, here we go again. The main subject is the same, but today we're taking a sneak peek at some relatively low-level things we need to know about data storage subsystems.

Read on ivanzakutnii.com or on dev.to

Hello, no memes today.
New part of the highload saga. Basic things about OLTP/OLAP differences and how OLAP storage systems essentially work.

Until next time.

Good evening, ladies and gentlemen.
Sometimes I wonder, looking at all this quirky crap - is there another kind of beauty in the software design universe?

Yes, there is. Yes, of course, it smells of FP... what did you expect? 😐

Hello, dear subscribers. I've been away for a while.
Well... some of you know why. There's been a lot of NOT REALLY INTERESTING work out there.

No interesting posts for today, just a small note on why I've changed the blog domain and what I am thinking about where this blog should go from here.

take care 😊

The nature of time is a cause of numerous bugs in computer systems, and not only. Take a look at this great post about time from Marc Brooker:

https://brooker.co.za/blog/2023/11/27/about-time.html#foot10

Thus shall you think of this fleeting world: A star at dawn, a bubble in a stream; a flash of lightning in a summer cloud, a flickering lamp, a phantom, and a dream.

Hello.
Nothing technical today, really.
Just some thoughts that struck me a few days ago.

ChatGPT is not your friend.

I have no doubts that you know about the "personal data flow" business; it is an old story — giant companies are "stealing" our data and selling it to each other.

I am not paranoid (maybe a little). They are not stealing. We are simply a herd willingly giving it to them.


So, OpenAI is no different at all.

There are a few amusing legal issues with them using YouTube videos for ML, but there's more from my recent experience.

A few days ago, I was having a small talk with ChatGPT about a very specific topic.

I hadn't googled it, or any related topics at all, not from my laptop, my phone, or any other device.

In this session, ChatGPT did not use Bing, yet the next few days my YouTube recommendations consisted of videos on that particular topic.

LMAO. Not surprised, just LMAO.

Still chilling from tech articles here, so here's one more unrelated to Pr0GramMeeng stuff.
Or... is it more related than any other topic?

Hey.

As a continuation of the last post, I want to talk about music.
For the time being, I thought that music affects people with varying degrees of distraction.

I keep hearing two opposite opinions:

- Music is distracting;
- Music helps to focus.

I believe the truth lies somewhere in the middle:
I think that songs distract much more than instrumental music.

•••

It's the case at least for me; I don't know how it works for you.
For me, if there are not just songs but also vocal samples or some samples mixed with a vocal synth, it grabs my attention instantly.
Really, it just flips a switch in my brain, and 70% of my attention immediately focuses on the sound. It's so strange.

It's the complete opposite with instrumental music.
Not any specific genre — I won't argue about music tastes because that's pointless.
Either music taste exists, or it doesn't.

I'm joking, sorry :D

•••

Well, yeah. Instrumental music.
And this is interesting! I found this study -> click.
Even though it has a small sample size, the answers and results sound pretty familiar to my empirical experience 🤔


A few weeks ago, I stumbled upon a "Music for Coding" playlist on Apple Music and clicked on it without checking the content.

It was just... full of Drake and other songs.

I'm just curious — How The Heck Can Someone Code While Listening To These Full Of "Some Sense" Tracks?
If you can, react with the 🎹 emojie to this post.

I can not.

Another interesting thing is that playing drums helped autistic teenagers significantly reduce hyperactivity and inattention difficulties.

But I don't play drums, and I'm not autistic .

I do love listening to drums while studying or working intensely.

For a long time, I listened to music with strict drum parts, like minimal techno. When I got terribly bored with it, I switched to extremely neuro bassy DNB stuff.
When I was burned out from working in DevOps outsourcing, I switched over to slamming deathcore bands ⚰️

No understandable words yet
🤣

So, the BPM of the drums doesn't really matter.

It seems that the drums matter, and the "gaps" between these drums.

•••

And still, perfect silence is better if one can focus without jumping around browser tabs procrastinating.

The problem is... It's so hard to find this silence.

Such silence is impossible in group offices, and such silence is not possible when working remotely from home if you have kids or a construction site just across your window.

I'm building up now a great (to my taste) playlist for programming, without words (99%) and mostly consisting of cinematic music, minor dub (like "Kryptic Minds"), and more intense electronic stuff (like "The Algorithm").

And it's working so well so far.

Will share it later.
