konsalexee··on Bootstrapping a side project into a profitable seven-figure business
The parrot on the OGs shoulder is the goal (besides raising the ARR lol)
konsalexee··on Show HN: NYC Subway Simulator and Route Designer
I love it! Amazing work.

A slider to do a bit of time-travelling if possible would be also a nice to have

konsalexee··on How to Network as an Introvert
> Start with: “How do you spend most of your time?” Not “What do you do?” It opens people up beyond job titles.

This is something that feels alien in SF people. A fundamental difference for example from Greece and people living in SF is this.

- Greek opening question: "Which city are you from?" - SF opening question: "Which company do you work for?"

konsalexee··on What 'Project Hail Mary' teaches us about the PlanetScale vs. Neon debate
It was really enjoyable to read. And I also do not read a lot of fiction, with my last book being the Hitchhiker's guide to the galaxy series.

My verdict is that Project Hail Mary was way much more engaging in terms of story-telling. The concepts were cool, and tbh I look forward for the movie and see if the adaptation will be nice

konsalexee··on What 'Project Hail Mary' teaches us about the PlanetScale vs. Neon debate
Long story short, I didn't want to make that analysis/distinction because it would miss the point.

They excel in their respective areas based on the architectural decisions they've made for the use cases they wanted to optimize for.

PlanetScale, with their latest Metal introduction, optimized for super low latency (they act like they've reinvented the wheel, lol), but they clearly have something in mind going in this direction.

Neon offers many managed features for serverless PostgreSQL that were missing in the market, like instant branching, and with auto-scaling, you may perform better with variable workloads. From their perspective, they wanted to serve other use cases.

There's no reason to always compare apples to oranges, and no reason to hate one another when everyone is pushing the managed database industry forward.

I second this!
konsalexee··on A new, faster DeepSeek R1-0528 variant appears from German lab
It is always about the trade-off between those two parameters.

Of course an increase in both is the optimal, but a small sacrifice in performance/accuracy for being 200% faster is worth noting. Around 10% drop in accuracy for 200% speed-up, some would take it!

konsalexee··on One Billion Cells – Another Multiplayer Demo with Clojure
What is the full stack you are using? What parts also require scaling up? DB, bandwidth orrr?

konsalexee··on Couchers is officially out of beta
Nice I was loving Couchsurfing until they started aggressively monetising it. Had really great experiences with hosting people! Hope Couchers will revive the great experience of hosting people
konsalexee··on Effectiveness of trees in reducing temperature, outdoor heat exposure in Vegas

I have no clue

konsalexee··on Effectiveness of trees in reducing temperature, outdoor heat exposure in Vegas
This is a repeating study, seeing this again and again, so not sure about its novelty.

In Europe we even assigned our first "Chief Heat Officer", which makes total sense.

konsalexee··on Nimtable: Open-source web UI to browse and manage Apache Iceberg tables
Amazing work! An interactive demo of how it work, before investing time to set things up would be really cool
konsalexee··on Show HN: TokenDagger – A tokenizer faster than OpenAI's Tiktoken
> simplifying the algorithm to forego regex matching special tokens at all

Does that mean there could be cases with less quality in terms of tokenization?

konsalexee··on Ask HN: What Are You Working On? (June 2025)
Cleaning up repo to open-source a remote pair programming software: https://gethopp.app/

Built in Rust(tauri), GoLang TypeScript and Livekit as WebRTC infra

Definition of testing straight into the production, "what could go wrong"
konsalexee··on Implementing fast TCP fingerprinting with eBPF
Sure, buts its a nice exploration to layer 4 type of detection

My personal thought experiment, or better explained as drawing parallels with game theory, around achieving immortality as humans—a feeling that we secretly but deeply think will be achievable anytime soon.
konsalexee··on We Chose Tauri over Electron for Our Performance-Critical Desktop App
Agree, and really minimal breaking changes, exceptionally smooth migration for us. We start a few months before stable v2 and we did not have any problem upgrading.
konsalexee··on We Chose Tauri over Electron for Our Performance-Critical Desktop App
Costa here, post author.

For the performance critical part, which is the screen-sharing and remote control, everything is done from Rust which is low level and gets the job done.

Native UI in this case wouldn't offer us much more. There is a case that maybe it could be faster in the video rendering in comparison from the browser's <video> tag, but we have not make any tests yet, maybe we should test this in the future.

konsalexee··on Lessons learned building a sub-100ms remote control app with Rust and LiveKit
Costa here, one of Hopp builders.

We chose to go native with Rust instead of just using the screen-sharing provided from Webkit for a few reasons: 1. Granular access to OS APIs. For example on MacOS you can select applications that you want to exclude from screen-sharing, which we know we want to use in the future. https://developer.apple.com/documentation/screencapturekit/c... 2. Being able to tweak the WebRTC client. In our case we patch libwebrtc for minor bugs, and tweak parameters to allow lower latency in video streaming 3.

Small post I made on how to debug performance of Golang executable.

Most posts online focus on HTTP servers and though it might be useful to some

Many front-end developers rush to call themselves “Senior” because they can build React apps, but how many truly understand the fundamentals of JavaScript?

After interviewing over 100 so-called “Senior” devs, I’ve found that too many struggle with basic concepts like closures, array methods, and loops. If you can’t explain why your JavaScript code works (or doesn’t), are you really a Senior Developer? What's your take and easy way to filter them out before reaching the code-pairing?

konsalexee··on Ask HN: Do AI-generated images ruin technical posts for anyone else?
Like the article having the word "Delve" into the very first sentences
konsalexee··on Ask HN: Do AI-generated images ruin technical posts for anyone else?
Its impossible though to be unbiased.

And I reflectm on my own biases, thus this observation.

konsalexee··on Ask HN: Do AI-generated images ruin technical posts for anyone else?
Smart, your joke is valid.
konsalexee··on Ask HN: Do AI-generated images ruin technical posts for anyone else?
Not so much. I believe in the wild there are less stock images in tech posts, as engineers would not even bother to search something generic.
konsalexee··on Ask HN: A Sci-Hub alternative for Medium Posts?
I use Brave and I do that.

The most confusing part for me is that I am unable to "clap" or bookmark the articles inside medium when I use incognito, in order to revisit them in a future time.

Bookmarking them in Raindrop is the current solution for me, but still I feel that there is a lot of friction going on.
