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”
Agile vs waterfall
Oh, the endless war. While principles of both methods can be explained within a paragraph, we see an amazing amount of £2000 courses, which will tell to you that user stories have to be only one user story size big and never bigger. It’s a blasphemy otherwise. “ACKCHYUALLY, user stories are in SCRUM and SCRUMContinue reading “Agile vs waterfall”
Learning progression
“Do you want a job at Google, Amazon, or Facebook? Sign up for these courses to learn to code/data science/cloud etc.” Or whatever these ads say. I’m not going to complain about it. It’s great we have a lot of resources and great resources to learn to code or learn other aspects of software development.Continue reading “Learning progression”
ETL vs ELT
Have you seen something like “Future is ELT!“, “ETL is dead! Long live EL(T)!” etc.? and you wonder what is it about? TL;DR; There is no point in distinguishing them! “One is Extract, Transform, Load. The other one Extract, Load, Transform. They are not the same you silly thing.” you say. Let’s break it down.Continue reading “ETL vs ELT”
The joy of cleaning up data
Some of us have a garage. And some of us use it as storage for things we don’t want to see. The rest of you will have to just use your imagination. You’ve seen an ad on an architecture firm doing remodeling of garages to a new hip space. Maybe you want some new spareContinue reading “The joy of cleaning up data”
