Managing data is a pain

That is probably not news to anyone who worked with any data. If not, I’m glad you have read the title. “But we now have all the data science and big data technologies, which solve it, so what you are on about?” Do you remember some of the movies, where the heroes are trying toContinue reading “Managing data is a pain”

Getting into Data field if you are not in tech

“Data science pays boatload of $$$. I want exactly that boatload of $$$.” You’ll start searching “Data science tutorial”, “How to do data science?” and Google will throw at you Python, R, unsupervised vs supervised learning etc. If you are not already a developer, technical analyst of some kind, I would say it’s not aContinue reading “Getting into Data field if you are not in tech”

FIRE movement – the good and the bad

There is a lot of good in the whole FIRE concept, a lot of nonsense, a lot of misdirection and lies, but a lot of good stuff. I think it is because it is hard to sell the concept same as get rich quick schemes. Even though you could still be sold a “trading system”,Continue reading “FIRE movement – the good and the bad”

FIRE movement – real people, real interviews

For those who don’t know this acronym but yet still found this post. FIRE is Financial Independence, Retire Early. Yes, that’s right. You can retire when you are 30 and live your dream life of sitting on a beach in the Caribbean, being server Pina Coladas all day and just getting fatter and fatter. ForContinue reading “FIRE movement – real people, real interviews”

Challenges of data engineering people don’t talk about

Imagine yourself being a data engineer. You wake up with birds chirping outside. Feeling fresh, so you quickly brush your teeth and take a shower. On a way to work you grab yourself a nice latte from your favourite coffee place. The one which you smell already before you turn the corner. The indistinguishable smellContinue reading “Challenges of data engineering people don’t talk about”

One year since the first post

Few things I have learned. I thought I hated writing, I was never good at any language grammar and my last bigger piece was my master thesis, which was a bit more painful to write. In reality, I don’t hate it. I quite like it, even though I’m not particularly good at it. A lotContinue reading “One year since the first post”

Rephrase a problem to solve it. Or not.

I was listening to a podcast talking about steps to financial independence. “Step #1: Create a plan how to become top 20% in your field.” I stopped listening after that sentence, so I might be speaking out of my turn here. However, it is pretty much “How to become financially independent” = “Get millionaire generatingContinue reading “Rephrase a problem to solve it. Or not.”

Authentic hire

When I set up this blog I knew it will be a strange mixture of random thoughts from my personal and professional life. I had to decide if to write it under my name, anonymously, and even if to split it into “personal” and “work-related”. I still remember, when my man P-Diddy asked me “WhatContinue reading “Authentic hire”

The third conditional

If I studied harder, I would have known the grammar of the third conditional. I always struggled with English grammar. Especially, I could never learn that darn third conditional. I always learned it for an exam and then forgot it immediately. It was a big deal though because I’ve heard third conditional in Czech almostContinue reading “The third conditional”
