grzaks··on Chess.com regional pricing: A case study
I was a Platinum subscriber for a few years. It's definitely not a scam, but in my opinion, they completely fail at detecting cheaters.

It's very frustrating when you lose a lot of games to cheaters. I cancelled my subscription and moved to Lichess — and although I still lose games, I don't feel like I'm being cheated nearly as often as on Chess.com.

Excellent! I was looking for a lightweight OSS alternative to Freshdesk/Zendesk and, honestly, didn’t find any worth deploying. Yours looks very promising, and we’ll definitely assess it.

We use https://cube.dev/ as intermediate layer between data warehouse database and Superset (and other "terminal" apps for BI like report generators). You define your schema (metrics, dimensions, joins, calculated metrics etc) in cube and then access them by any tool that can connect to SQL db
grzaks··on How to learn chess as an adult (2021)
My biggest frustration with chess online is the huge number of cheaters on platforms like chess.com and lichess. It really takes the whole fun away.

I never really understood WHY people are cheating in online chess games. There is no fame, no money in it. This is puzzling for me.

My frustration is that chess.com and lichess are extremely week at finding and banning cheaters. Sometimes is sooo obvious, when for example somebody blunders a piece in first few moves and from this moment starts playing just perfect moves.

grzaks··on How to learn chess as an adult (2021)
Yeah. You have to realize that in chess there are two players and one of them is going to lose. Sometimes it's you, sometimes it's your opponent. To progress in chess you need to win more games than you lose. 50.5% win rate is enough in the long term.

My suggestion based on my own emotions with chess is that you should start playing quick games like 3+2 or something. The time and emotional "investment" in those games is low enough that you might not care when you lose. Just start another game and try again. Losing classical game that you were playing for 2 weeks is a different beast.

> I think there are a lot of people that would like to pay for IDA but can't get it.

Many years ago we wanted to buy IDA Pro license and were quickly declined because we had whois privacy protection enabled on our domain.

grzaks··on NSO Pegasus was used by Polish gov against opposition during 2019 elections
Not all polish press. Just the national, govt controlled television. The same that used materials from compromised smartphone of Krzysztof Brejza in 2019

PiS, the party ruling in Poland since 2015 used Pegasus spyware about 30 times against Krzysztof Brejza, senator and chief of opposition party electoral campaign during 2019 elections.

Please be aware, that the most popular emule server software available many years ago was backdoored. That's why it was distributed as a binary, without code.

Polish society is still liberal. Please do not think our current government and their actions are representative of what Poles think and support. Majority is at the moment fighting our own government ...

grzaks··on Postmates earned 400% more on a delivery than the delivery guy
Typical mistake. Service price is never based on the costs of development but on a value it creates. You might have extremely expensive IT solution that creates no value to anybody and is worth $0. You might have email-based manually operated business that provides service worth thousands USD.

Postmates creates value both for you and the delivery guy. After all - you used their service for some reason and paid for it right? You get the quality service, delivery guy gets the demand for his services.

Alternatively the delivery guy could develop an app for himself only, put it on the appstore and wait for you to download it. But he would never earn anything this way.

grzaks··on Lyft Plus
It's most probably because they have KPIs to fulfil set by Uber and they are gaming the system that way. If I were Uber I would definitely monitor quality of service by measuring the arrival times for each driver.
