Avalaxy··on Postgres data stored in Parquet on S3: LTAP architecture explained
Super cool stuff. Being able to combine your analytical platform and transactional database into one storage layer without having to set up ETL pipelines in between is really a game changer. Especially since it's just postgres, instead of some proprietary database.
Avalaxy··on Not everyone is using AI for everything
Maybe in your country they also don't have a deposit on bottles/cans, making it pointless to go through trash cans?
Avalaxy··on Statement on US government directive to suspend access to Fable 5 and Mythos 5
You mean randomly attacking countries like Venezuela or Iran?
Avalaxy··on Digital Sovereignty Becomes an Imperative as the US Reads Dutch Emails
That's not the case. Smals will use it, that doesn't mean that the rest of the public sector has to follow.

The netherlands as a whole should do this. Not just holland.
Avalaxy··on Television is 100 years old today
Does anyone here still have television? Ever since I moved out of my parents house (15 years ago), I never had a TV subscription. I did own a TV screen, but only to run apps like Netflix and Youtube. I'd rather have a simple monitor without the TV options to do so, but strangely that never existed or was too expensive.

Edit: to make it clear, I absolutely did not miss having TV for even a second in all of those years.

Avalaxy··on EU moves to ease 2035 ban on internal combustion cars
Absolutely ridiculously unambitious plan. I thought the 2035 deadline was already void of any ambition or urgency. Imho it should have been 2030 or earlier... Every single year counts, we are past several tipping points already. We don't have the luxury to sit on our hands for another 10+ years, as much as people would love to close theirs eyes and pretend that all of this isn't really happening...
Avalaxy··on I wasted years of my life in crypto
I spent 2014 to 2016 working on crypto. I built crypto apps for a lot of companies, including some that are very very big now. Back then, I really believed in crypto. But after the Xth crypto bubble popping, I gave up. So much time had passed, and nothing was changing (for the better). Banks were NEVER going to adopt this (at least not any blockchain that the general public can profit from) and it would NOT dramatically transform the financial system the way I thought.

I had a ton of bitcoins and ethereum. I even bought ethereum in the presale. Present day value would have been around 5 million euros. But I sold it all back then, because I saw that crypto was never going to make a significant impact.

It turned out, I was right. Most of the bitcoin ATMs disappeared, most webshops stopped accepting it, it plays almost no role at all in the financial world. But I overlooked one major factor: the value of these cryptos isn't based on anything else than thin air. People are willing to pump anything as long as they can personally profit from it. And yes, the famous saying applies here: the market can stay irrational longer than you can stay solvent. I saw the fundamentals correctly, but the sentiment wrong.

Avalaxy··on Ticker: Don't die of heart disease
You can order all blood tests you want online in NL. E.g. bloedwaardentest.nl, mijnlabtest.nl, perfectlab.nl. But it isn't cheap so you need to know what to test for to keep the price reasonable.
Avalaxy··on Ticker: Don't die of heart disease
Funnily enough, the things you can do to prevent stroke line up entirely with the things you can do to avoid heart disease.

That didn't hold true for Intel, which once had a monopoly.

I'm so sorry for your loss :(
Avalaxy··on China is eating the world
I would love to NOT have those chains in my country. Especially mac donalds, I associate with trash. Both trashy people, as well as literal trash laying on the streets.
Avalaxy··on I launched 17 side projects. Result? I'm rich in expired domains
This actually killed my motivation to do some of my side project ideas. I would spend a lot of time writing very good specifications, setting everything up for succes by really finetuning my prompting and context, but then the AI would output something that looks impresssive but is completely full of mistakes. And it would take SO many tries to make the AI fix it, but every time it creates more and more bloat, and introduce more and more issues. Until the point I decide to throw away everything the AI produced, and try it from scratch again with a different prompt.

Eventually I spent so much time trying to make it work, only to remain empty-handed.

Avalaxy··on One diet soda a day increases type 2 diabetes risk by 38%
> Nobody drinks artificially sweetened soda unless they have a problem because it just tastes bad. A healthy person would just pick soda sweetened by sugar.

What a bizarre statement. I have no health problems and will always pick the 'zero' variant of any soda, because to me it tastes exactly the same, but minus all the calories.

Avalaxy··on Ask HN: Using AI daily but not seeing productivity gains – is it just me?
Interesting read! My personal experience with Cursor aligns with this. The initial result of my prompt was stunningly good, but adjusting the code afterwards was not a great time. It also aligns with the software 3.0 concept pitched by Andrej Karpathy, making the english language (or other natural language) the new 'code'.

Avalaxy··on Prompt engineering playbook for programmers
I feel like all of this is nonsense for people who want to pretend they are very good at using AI. Just copy pasting a stack trace with error message works perfectly fine, thank you.
Avalaxy··on The heist that made the Mona Lisa famous
Really? This is why the Mona Lisa is famous? Not because of any intrinsic properties of the painting itself?
Avalaxy··on HPV vaccination: How the world can eliminate cervical cancer
Wow, thanks for your story. I'm terrified of getting this too, and I've been wondering what it's like.
Avalaxy··on HPV vaccination: How the world can eliminate cervical cancer
I can't find anything about this, do you have any papers?
Avalaxy··on HPV vaccination: How the world can eliminate cervical cancer
> There is evidence that it helps reduce the risk of progression to a cancerous state

I have not been able to find this. Do you happen to have a link to a paper?

Avalaxy··on HPV vaccination: How the world can eliminate cervical cancer
I really wish we had therapeutic vaccines against HPV. As a man, I always got told "it's not for men", followed by "it is also for men, but only if you never had sex", followed by "it's also for men who had sex, but only to a limited age".

As a male who meets all the criteria to be in a high risk group for HPV throat cancer, and who is dealing with a persistent HPV infection (as proved by warts that won't go away), I'm really sad that I may one day at a young age get cancer in my throat, and there is nothing I can do about it to prevent it. I wish we would put the same amount of energy into inventing vaccines that suppress the virus, or help the body to get rid of them.

Avalaxy··on How to deal with people who are bad at explaining?
I feel like this only works in small groups. Have you (repeatedly) done this in bigger groups? I feel like that's a great way to make everyone hate you. Although I must say that sometimes I have asked this question, and people seemed thankful because they also didn't understand a thing, but simply didn't dare to ask. This is a bit tricky, because if nobody asks questions, I feel like they all understand and I'm the only dumb one who doesn't get it.
