melting_snow··on Ask HN: Who is hiring? (June 2026)
Exeon | Remote (Switzerland and Germany) | Senior scala developer

We're Exeon - a Swiss cybersecurity company out of Zürich that uses AI/ML to detect sophisticated network attacks that conventional tools miss. Think NDR (Network Detection & Response), but actually smart.

What you'd actually be doing:

- Owning architectural decisions for new features and legacy refactors

- Mentoring backend teammates (we're growing)

- Contributing to both the backend and the GUI layer

- Working closely with a genuinely international team

What we're looking for:

- 8+ years of software engineering experience

- Strong Scala skills with a taste for architectural thinking

- You know when to refactor and when to ship

- Comfortable with tests (unit + integration) as part of normal coding, not an afterthought

- Fluent English; German is a bonus

melting_snow··on Brazil's Pix payment system faces pressure from Visa and Mastercard
> but because it can give ideas to other countries doing the same

This is happening right now in Europe. You have systems like Blik, Twint, Swish etc.

I know that at least Blik is working on making it possible for international payments.

melting_snow··on Ask HN: What are you working on? (February 2026)
Im working on ebpfence https://github.com/CucumisSativus/ebpfence

I want to create a tool that would automatically block the stealers from stealing your previous credentials or crypto wallets. I had this idea after the Shai-Hulud attack

It's an experimental side project, but so far it looks very promising.

I was in a team that built a bigger telco project for machine to machine communication, using akka actors. It was okayish, the only thing that I hated was how the whole pattern spread through the whole code base

Burning coal and wood wouldn't be that bad. Unfortunately its quite common that people burn their trash

The issue with solid-fuel ban is that its banned only inside of the city itself, not in the surrounding towns
melting_snow··on Kraków, Poland in top 5 worst air quality worldwide
During covid, when car traffic went to almost 0, the air quality was also extremely bad. Its mostly coal in the houses plus some people are not even using coal in their heating systems
melting_snow··on Kraków, Poland in top 5 worst air quality worldwide
There are many houses in Poland that are using coal heating, and unfortunately a lot of people burn there their thrash. Kraków is surrounded by smaller towns and villages, where single family houses are common. To make things even worse, Kraków is in a basin, which makes the air flow even more difficult. If you add there years of city mismanagement when it comes to air flow, you land in such a situation
melting_snow··on A decentralized peer-to-peer messaging application that operates over Bluetooth
Im not saying that those are the only use cases, but I really see that there multiple other apps that make the "normal" communication much easier.

I see two use cases: * Communication between protestors * Illegal activities, but here I can imagine that bluetooth range is too small
