I lead engineering teams @happening_xyz building sports betting products. I occasionally have opinions on tech, business, strategy (sort by confidence desc).

@GergelyOrosz Out of curiosity, where did you get the 26-30m estimate from? iirc, GutHub had about 100m accounts in 2023 (so, pre-ai). Stack Overflow has about 20m accounts.

@GergelyOrosz Not to mention many who probably nuked their sites in a panic-induced rush to stop the bleed, thereby creating unnecessary work and outages to customers.

@AWSSupport Nearly had a heart attack 30mins ago.

@GergelyOrosz “Organize world’s information and make it universally accessible” and “Don’t be evil” were quoted frequently 2014-2019, but I suspect a lot of that changed as internal narrative shifted in recent years.

@grok @elonmusk MOXIE was run in Mars atmosphere, is that really comparable to operating on Earth?

Can you elaborate on the photoelectrochemical systems efficiency point you made? Where can I learn more?

[Ivan Klaric @iklaric]

@grok @elonmusk Do we have a more efficient way of converting CO2 to oxygen?

Obviously, still a pretty good point on deserts (or roofs for that matter).

@ivanburazin I've had very similar thoughts and did a talk about it ~1y ago: https://t.co/6VpG8kPhPk

My conclusion though was different - the only moat that's long term sustainable is a healthy, self-healing culture - it's what allows you to continuously adapt to a changing environment.

@velimirgasp Fortnightly! You get scholarly vibes included in the price :)

@gunnarmorling *back then*

@gunnarmorling IIRC, there was limited SQL in MySQL :-)

@d_stepanovic I'm more interested in the questions that have to be answered in order to try to estimate effort on a project than the estimate itself.

Understanding what are the hard parts and solving them first is the useful part.

[Ivan Klaric @iklaric]

Fairly happy with how the talk went - there are obvious thing to improve in delivery, but I think I got the message across. LMK what you think.

So, we're organizing a hangout at our Zagreb office and I'll be talking a bit about everyone's fake Peter Drucker quote. I was told there'll be beer as well.

@gunnarmorling @NikkiSiapno With idempotency, replaying multiple, potentially unrelated messages isn't an issue.

And with single-writer principle, you ensure the same key (e.g. customer-id) is always processed by the same pod, allowing for eventual consistency.

[Ivan Klaric @iklaric]

@gunnarmorling @NikkiSiapno Got it, thanks. Transaction support is frequently first to die when you want to cheap horizontal scaling :-)

We've successfully side stepped issues you mention by designing services with single writer and request idempotency principles in mind.

[Ivan Klaric @iklaric]

@gunnarmorling @NikkiSiapno Can you expand on the concurrency control issue? What behaviour would you expect in Kafka and why is it crucial for event sourcing?

@velimirgasp meni je ovo vise "po duhu svetom" djir

@velimirgasp lik je yoloao na doge. onda je jos i malo zaradio.
