A fab takes years to build even when you have the necessary know-how. If you don't it'll take some additional experimenting before you can compete with the established manufacturers. By the time you can produce a usable chip the shortage might be over.

Slack recently introduced this option where it can tell you what kind of animal you are (not kidding) based on the conversations you had. When I saw this I immediately thought "managers pushed poor folks at Slack to incorporate more AI into the product".

In Poland it's on 26th of May.

Anecdotal, but the company I work for offers to the juniors only +15% to what it used to offer 15 years ago. The salaries are growing mostly because previous government introduced huge increases to minimal salaries, but I don't feel the wages in IT grew significantly over the years. Which actually make sense - we used to have huge disproportion between regular worker salaries and IT ones, now the difference is getting smaller.

I know that Ukraine takes Polish experiences into account and consults with Poles on what went well and what not during our post-communist transformation and later the EU membership. They are keen on not repeating our mistakes. There were many Ukrainians working in Poland long before the full scale work so naturally many Ukrainians were looking at Poland hoping that their country could eventually replicate polish success.

But I don't think our example has an effect on morale and spirit of resistance.

I'll use the opportunity to ask what's the cheapest cold storage in the EU? I am looking for an alternative to AWS Glacier Deep Archive.

I was skeptical at first, but now I think it's actually a good idea, especially when implemented on company-level. Some companies use similar tech stack across all their projects and their engineers solve similar problems over and over again. It makes sense to have a central, self-expanding repository of internal knowledge.

A couple of years ago someone associated my email with their bank account in Santander UK. I tried to get in touch with Santander but turned out that the only way to do so is to either make an international call (I don't live in UK) or send them a paper letter. I gave up and just routed these emails to separate folder.

Long before AI era I read an article about homilies exchange online forum in Poland. The priests spoke how they struggle to come up with a fresh content every week for Sunday masses. AI is not the source of the problem, it's just an attempt at a solution.

Like the article mentioned many EU countries have their own payment systems. The challenge is not to build something from the scratch but rather to make existing solutions interoperable. The first talks about cross-border integrations started many years ago but they went very slowly. However, some work is being done, just a week ago a first transfer was done from Spanish Bizum to Polish Blik.

TBH many European payment apps use the phone number as an ID and people seem to love it. I share the privacy concerns but if I don't want someone to know my phone number I just give them my IBAN.

In Poland all transactions related to housing or land must be notarized with both buyer and seller present, the notary is supposed to check their IDs. Sadly it happened a couple of times that scammers presented a fake or stolen ID to a notary who did not recognize the forgery. Nowadays you can mark your personal number (equivalent of SSN) in the central, governmental database as restricted. This prevents notarized transactions, bank loans or issuing SIM card duplicates in your name. When you need a loan or buy a property you just log in to the system (or open the governmental app) and uncheck the checkbox.

This is pretty much a standard salary range for a Senior Dev in Poland. Outside of Warsaw it can be even lower.

Animals on tracks remain a problem, although they do not pose risk to human life (just damages to the trains). One of the attempts to protect animals include acoustic deterrents, here's a Polish one as an example [1] but they are manufactured around the world. The Polish one plays sounds of predators, dying creatures, hunting dogs, etc to scare away forest animals (search for "UOZ-1" on youtube if you want to hear the sounds). Such devices significantly lower the number of collisions but unfortunately they are not 100% effective.
