czechdeveloper··on Global Glacier Extinction Explorer
Why do people like to pretend AI is reason for climate change?

Climate change has been problem for way longer.

czechdeveloper··on Surely the crash of the US economy has to be soon
Mini stocks were traditionally used as way to invest in asset as a security. But currently with all the ETFs that are backed with physical asset itself, I'd choose that way.

Holding asset yourself (gold) causes logistical issues and massive buy/sell split on your side, but it has some advantages too.

czechdeveloper··on Surely the crash of the US economy has to be soon
Assets traditionally used for such hedge are already massively inflated (look gold an silver price charts), so I'm not sure it's worth it.

This all depends on what timelines you work on, how many assets you are trying to protect.

Alternatively you protect yourself by lowering your dependence on steady income.

czechdeveloper··on Gmail will no longer support checking emails from third-party accounts via POP
They did the same with free version of Google Workspace. It's just no longer free.
czechdeveloper··on MCP Specification – version 2025-06-18 changes
Nango is cool, but pricing is quite high at scale.
czechdeveloper··on LLM function calls don't scale; code orchestration is simpler, more effective
My daily job by now is massively using AI to develop AI agent designer, which means a lot of stuff like this.

I really did not even want this, it just happened.

czechdeveloper··on Mongo but on Postgres and with strong consistency benefits
I suggest you add https://github.com/tensorchord/pgvecto.rs for vector search as well
czechdeveloper··on Why we no longer use LangChain for building our AI agents
I used langchain in one project and I do regret choosing it over just writing everything over direct API. I feel their pain.

It had advantage of having standardized API, so I could switch local LLM to OpenAI and just compare results in a heartbeat, but when I wanted anything out of ordinary (ie. get logprobs), there was just no way.

czechdeveloper··on Which Electric Cars Have Bidirectional Charging (V2L, V2G, V2H)
Vehicle by definition can't be connected to the house constantly. I can imagine this lowers need for house battery size, but not need for it's existence. House power consumption is very random.
czechdeveloper··on Alexei Navalny has died
This sounds so random. Did Russia ever proved they can do AI in any significant capacity?
czechdeveloper··on Ask HN: What is your go-to stack for the web?
BE: .Net minimal API, Entity Framework (SQLite or PG as database) FE: React + Tailwind and few other libraries
czechdeveloper··on Implementing a ChatGPT-like LLM from scratch, step by step
Such a great source of information. Thank you.
czechdeveloper··on Goodbye non-KISS appliances
By now, making UI with (by now not completely) SPA frameworks specifically made for that task is just better developer experience. I won't go back to pretty much html string concation via templates. Why do people keep pretending it's better in any way is lost on me.
czechdeveloper··on What PWA Can Do Today
Not everyone has apple devices to test on for their toy project. I know I don't.

czechdeveloper··on I stopped cosmonauts from carrying guns (2014)
As a gun enthusiast, that sounds really impractical. Amount of compromises involved must have made it bad in all use cases.
czechdeveloper··on Ask HN: What apps have you created for your own use?
I made universal CLI project where adding new function as is simple as adding new class with arguments parsed into an object.

It has 49 actions now even when I keep removing obsolete ones.

I also made PDF viewer for comparison of 2 documents - synchronized zoom and scroll, even overlay.

czechdeveloper··on Methane under the seabed is thawing as oceans warm
Because it's a pipe dream. We are our bodies, they not something to be overcome.
czechdeveloper··on Lapce Editor 0.3
Looks better than last time I checked. I like the idea and it's getting there.
czechdeveloper··on What's new in C# 12: overview
With small classes and dependency injection as fist class citizen, default constructors make sense for developer ergonomics.
czechdeveloper··on Tech giants are hijacking the internet
It's not that article is old, but that this has been happening for a very long time.
czechdeveloper··on Productivity has grown faster in Western Europe than in America
It's not like engineers struggle, so playing such games against your colleagues is totally moral failure.
czechdeveloper··on Zuckerberg,Bezos,Gates.Behind Every Self-Made Millionaire Is a Father with Money
To be honest, I do care way more about how horrible work conditions they provide in their companies. Especially to the more vulnerable and low paying positions.
czechdeveloper··on Zuckerberg,Bezos,Gates.Behind Every Self-Made Millionaire Is a Father with Money
You know what is difference between a million and a billion?

Approximately a billion.

czechdeveloper··on You Don't Need UUID
Plus I could easily represent UUID in base64, such as JlEt5BSYe0enwB7nxl5V6g, which makes it shorter if I need that.
czechdeveloper··on I don’t want to grow my freelance design studio into an agency
You're giving me hope, because this is exactly my plan now.
czechdeveloper··on A Critical Analysis of the What3Words Geocoding Algorithm
All the more reason to not use it as they may turn to some way of aggressive monetization to fix that.
czechdeveloper··on Show HN: LearnLingo – Converse with an AI-powered language tutor
While that answer is not complete, it's also definitely not "no answer". I agree that there should probably be some company associated, but as MVP from single developer, do you expect to get his full address too?
czechdeveloper··on It doesn’t take much public creativity to stand out as a job candidate
I understood it more as taking current US gun debate to Trademark Policy. Very weird.
