It’s actually easy and straight forward to become an avogadrillionaire, on paper that is, but still an avogadrillionaire: issue a token with a supply of 6.02*10^23, sell one token for $1, bam, avogadrillionaire

I think it’s rather because of scarcity: you can’t scale and automate land/prime-location land

I have this personal theory that some time after an external stress-related impulse (be that negative - ww2, cold war, becoming paralyzed, etc, or positive - inheriting money, winning the lottery, not having to work for the rest of your life, finding the love of your lufe, etc), the brain adjusts and one comes back to the baseline of their perceived normal stress level. And that’s why we see people who are always happy and seemingly stress free despite having nothing, and ones that always seem stressed to the max despite having everything

The blockchain hosting companies like infura live by offering API access to ethereum, solana, binance smart chain, etc. I’d say they are now rather hosting companies because these blockchains are huge and a PITA to host reliably, but back in 2017 it was possible to host them on a personal computer

Am I the only one thinking that going back full circle to server side rendering, but to a way more convoluted way of having it, is actually a regression rather than evolution technologically? We had SSR since the times of Perl, PHP, Python, Ruby and even express. But in a way more straight forward way of doing it: here’s some HTML, with some db queries that takes data, puts it in said HTML and sends it to the browser. Today we have react components that can be executed both on the server and on the client, we need at least 2 servers - one for the frontend and one for the backend, we have to hydrate the components when we render them server side, but not when rendering them in the browser, etc. I feel like we’re inventing stuff just because we can and there’s a huge cohort of engineers who complicate their development experience just because.

I used to be a hard core stackoverflow contributor back in the day. At one point, while trying to have my answers more appreciated (upvoted and accepted) I became basically a sychophant, prefixing all my answers with “that’s a great question”. Not sure how much of a difference it made, but I hope LLMs can filter that out

Show HN: Bulletproof sessions – secure, cookieless session handling

tudorconstantin — Mon, 24 Mar 2025 15:40:35 +0000

I had this idea for a few years already and now I also managed to implement a proof of concept for it: instead of relying on cookies or tokens to identify a user, have a service worker intercept and sign all the requests to the server (with a private key generated when the service worker is initially installed).

The server identifies the user based on the public key corresponding to the signature.

BAM! no more cookie sessions, so no more sessions hijacking and session replay attacks.

I also wrote a blog post [0] detailing some advantages over the traditional session handling mechanisms, but I feel this enables endless possibilities.

Appreciate your thoughts&feedback!

Chess puzzles work quite accurately IME to assess my mental capabilities for the day. Especially the puzzle storm on lichess. There are enough puzzles there to not repeat themselves too often and they are rated so they have similar difficulty for the same rating. In my good days (lots of sleep in previous nights) I have way better scores than on my bad days (30-40% better)

tudorconstantin — Sun, 09 Mar 2025 14:54:50 +0000

A bit unrelated, but try having l theanine after a night of drinking: it makes you wake up fresh and without a hangover because it speeds up alcohol processing and it metabolites by the liver and also prevents alcoholic liver damage. Me and all my friends who tried it say “i wake up totally fresh after theanine”. There’s also a study confirming this: https://pubmed.ncbi.nlm.nih.gov/16141543/

But once that bubble (and any other one) burst, it never reached new highs again. The bitcoin bubble burst multiple times and got back higher and higher

I think “puzzle storms” on lichess can be considered a way of fiddling with chess instinctively. I found it also helps with not giving pieces for free when playing full games and also seeing the blunders your opponent makes way faster

New comment by tudorconstantin in "Tornado Cash verdict has chilling implications for industry"

tudorconstantin — Mon, 20 May 2024 02:45:44 +0000

TL;DR: the Tornado Cash developer, Alexey Pertsev, was convicted by the Dutch authorities to +5 years in prison for money laundering for developing Tornado Cash (not for actually laundering any money).

I wonder: will they go for the monero devs next? What about the creators of wallets that don’t require KYC before creating an address?

I read some time ago on twitter something along the lines of “if you run enough A/B tests, you’ll end up with a porn website” and I guess that’s what the future of high-engagement-web reserves us

I think this could be implemented without listening: I am physically meeting with my friend X who is researching online for his new acquisition (or he already got it). The more obsessed he is with that, the bigger the chances he'll tell me how awesome such a thing is.

So algorithms can percolate his interests to me after we meet and some time it would happen that we talked about it too.

The tech lead I was working with a few years ago was absolutely certain vanilla js is a framework. To the point he dismissed some candidate for not knowing about it. I guess he was referring to this one http://vanilla-js.com/

tudorconstantin — Sat, 12 Mar 2022 09:22:11 +0000

After working for the past ~3 years with a microservice oriented architecture, I can only imagine the horrors of having to work on a project built with lambdas. We're a team of only 2 backend engineers which have to touch up to 4-5 repositories for implementing some features. Orchestrating the deployments of the changes to all those repositories, debugging across all those microservices, having sane rollback strategies for each feature, really brings down the developer experience and speed of development when compared to working with monoliths. I don't want to imagine what happens when one would have to treat every function as a separate entity. Yes, these architectures have their benefits, but for 99% of the projects in the wild the burdens outweigh the benefits drastically: every day, for every feature developed, for every deployment and for every bug being debugged.

I loved the article. I worked in sales for ~2 years before starting my career as a software engineer +15 years ago, so knowing how downputting rejections are, I try to treat all the salespeople as human beings, so I try to respond to all of them. My strategy is to make them refusing me, by requiring "only" a +30% i increase.

New comment by tudorconstantin in "Saving on egress switching from AWS to Hetzner"

tudorconstantin — Tue, 25 Jan 2022 06:36:44 +0000

Watch out that electricity costs went up significantly in Europe in the past months. I am a happy hetzner customer since 2012 I think. Their server monthly costs were just a bit higher than my electricity bill would've been if I were to keep a machine up 24/7 at home, so I rented a machine from them having the hardware basically for free.

Last week I got an email from them saying my server cost would increase from 30eur/month to 48eur/month. I can take afford the increase, but I wonder how many companies with infra bills of tens or hundreds of thousands will be able to afford a 60% increase in hosting costs.
