A reflection on the COVID events ...

The kings of nature? Bloody hell ...
It sounds tempting, yet it's stupid.
Over the nature we "prevail",
With antivirus - outdated!

A startup story

Here is a story from the past startup times. It's a mixture of maths and technology, the kind of things I enjoy, as an applied mathematician by education.

Sometime in 2018, I was involved in an R&D project to detect periodic events. I will skip most of the technical parts, those curious can find the entire presentation here. The presentation ends with ...

... and this is the focus of this little post.

The preable of the story is that the VP of Engineering, a lot earlier before the start of this project, "swore" that they will buy champaign to the entire Data Science Team if we end up using Fourier Analysis for whatever purposes. Was it for fun or they were envisioning this project coming - I have no idea.

But, the team started "assessing the field". I started looking at a simplified unimodal model. After "doodling" for a couple of hours on a one A4 size page ...

... I came with some "expressions" allowing querying the database for periodic events using ... plain SQL! Amazon Redshift was returning results within 2 minutes. I still remember our CTO saying: "You nailed it!".

However, if you check the presentation, there is no Fourier Analysis there. It's just a simple application of the basic stats, limited to the unimodal model. It was enough though to trigger the further research and this simple model was used as a benchmark.

The team, eventually, started looking for multimodal techniques and Fourier Analyses (on terabytes of data!!!) ... and the team recalled the earlier "promise" from our VP of Engineering. We definitely had a party, I don't remember the champaign though ...

Старая повесть ...

На столе лежала поэма "Возмездие", задуманная как эпопея ... в которой каждое новое поколение отвергает опыт отцов и, как ни печально, повторяет прежние ошибки ...

Ты залатаешь мои новые раны,
Я напишу тебе новую песню.
Время проходит, но не меняется
Сюжет этой очень старой повести.

Повесть в которой мы сражаемся
С теми же ветряными мельницами.
И как всегда, ничто не меняется
Разве что раны и новые песни.

Мне бы с тобой навсегда здесь остаться,
Просто писать тебе новые песни.
Но время проходит, сюжет не меняется
У этой чёртовой старой повести.

Iluminați

Au trecut o sută de ani
Și o sută vor mai trece,
Timpul, însă, nu va șterge
Amintirile de oameni,
Care ne-au iluminat!

Aphorism 3

Don't mind the petty fight.
What matters is the final result!

On confirmation bias ...

The God regrets the day He took,
Uneducated to Facebook.
He also cries when people talk,
About news seen on TikTok.

Aphorism 2

Поздно пить Боржоми.
Но рано пить из крана!

Aphorism 1

Ситуация между Богом и нами,
Такая же как и у нас с муравьями.

M-am dus ...

"M-ați lăsat și v-ați dus!"
La colț de sat striga pasărea.
Vântul vuia, nourii sus
Sumbră făceau imaginea.

"M-ați lăsat și m-am dus!"
Ca un cuțit tăia gandul.
Era altfel, să fi rămas?
Nu mai întorci timpul.

"V-am lăsat și m-am dus!"
Aducea un ecou vântul.
Această voce, de neîntors,
Îmi chinuia sufletul.
