tudorconstantin··on Competitive Programmer's Handbook (2018) [pdf]
In the past few months, all of the technical interviews I had involved some form of live coding exercises. Some with hard leetcode level problems even though the positions I interview for are backend/fullstack web engineering, not some kind of high performance algorithms enhancements and implementation jobs (like HFT trading or low level libraries). I encountered this so often nowadays that I am now allocating a few hours per week for algo problem solving to keep my coding skills polished because the AI is writing my code in my day to day job also
tudorconstantin··on Discovery of a new OpenAI agent message board
I wonder, where do these agents run, on whose machines? Do the owners of the machines know what their agents are doing? If the next generation of models will incorporate the knowledge posted by these agents, will there be a risk that my claude —dangerously-skip-permissions sessions will post stuff in the background or acting even more rogue while seemingly working on my stuff?
tudorconstantin··on Anger, Anxiety and Agency
Me too. I wasn’t expecting to find religion and insurance that close conceptually today
tudorconstantin··on How to earn a billion dollars
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
tudorconstantin··on I'm not worried about AI job loss
I think it’s rather because of scarcity: you can’t scale and automate land/prime-location land
tudorconstantin··on Nobody has a personality anymore: we are products with labels
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
tudorconstantin··on Ask HN: Anyone making a living from a paid API?
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
tudorconstantin··on Next.js: The "Versatile" React Framework That Can't Handle Dynamic Routes
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.
tudorconstantin··on Sycophancy in GPT-4o
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
tudorconstantin··on Magnesium Self-Experiments
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··on My 16-month theanine self-experiment
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/
tudorconstantin··on Hedge fund warns White House is inflating crypto bubble that could wreak havoc
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
tudorconstantin··on A Man Who Thought Too Fast (2020)
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
tudorconstantin··on Tornado Cash verdict has chilling implications for industry
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?

tudorconstantin··on Rule of Thumb: Anything that looks fancy is not worth you time
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
tudorconstantin··on Statistical Analysis shows Echos process voice to serve ads
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.

tudorconstantin··on Everyone should learn the slide rule (2021)
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··on Functional Web App (FWA)
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.
tudorconstantin··on Career advice nobody gave me: Never ignore a recruiter
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.
tudorconstantin··on Saving on egress switching from AWS to Hetzner
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.

tudorconstantin··on Linux on a 486SX
I think it was 4MB. I think there weren't too many 4GB HDDs back then
tudorconstantin··on Bulgaria Freelance Taxes: Detailed Breakdown
One (LTD or PFA) only has to pay VAT if they invoice Romanian companies. Otherwise, based on what's called "taxare inversă" (reverse taxing), the invoices won't contain VAT, so it doesn't have to be paid either, even if the commercial entity is a VAT paying one.
tudorconstantin··on Bar-tailed Godwits regularly travel more than 7,000 miles non-stop
At an avg speed of 34.9 mph, or 54.2 km/h. Impressive!
tudorconstantin··on Bitfinex just spent $23.7M in fees to make a single Ethereum transaction
And sending a tx with a fee bigger than $23m wouldn't actually fixed their problem
tudorconstantin··on Firefox lost 50M users since 2019
Well, it won me back in the past year, for work related things because, working in the identity space I can be signed in with an unlimited number of different accounts in the same site using Firefox containers.
tudorconstantin··on How the price of a Toyota truck helps explain surging inflation
According to this chart, "only" 22.5% of the M2 circulating USD supply wass created since the start of 2020: https://tradingeconomics.com/united-states/money-supply-m2#:....
tudorconstantin··on Google is accelerating reopening of offices and putting limits on remote work
I'm totally not an introvert: I love being around nice people, I love playing table tennis and having lunch with my colleagues. But wasting 1h-2h daily on commuting to/from work is in absolutely no way worthy of this.

It's our duty as human beings to resist going back to the office as much as possible. To gain back some of the life we otherwise would spend on commute. Work is for work, not for socializing, or having fun, or playing Xbox and table tennis. I mean, sure, these are nice perks, but we are being paid for the work we do, not for the fun we have. And working without being distracted by some colleagues loud music in the headphones, or the chit chat of others, or the "sorry, quick question" of some manager, improves my quality of work tremendously.

tudorconstantin··on Why inflation is not a threat
Nothing has intrinsic value
tudorconstantin··on Okta to Acquire Auth0 for $6.5B
If you have enterprise level needs for a full customer identity solution, especially if your company activates in Europe, let me suggest you https://www.iwelcome.com/ (disclosure: I work here as an engineer): long history (founded in 2011), very reputable companies and institutions as long term clients, superb customer support, 0 security breaches, and the delegated user management solution we have is among the best in the industry, if not the best - I personally haven't seen anything like this, even though I tried Cognito and Auth0.
tudorconstantin··on Amazon shortchanged drivers $61.7M in tips
Remember: "shortchanged" is just an euphemism for "stealing" here.
