Is it time to build my own CMS?

This website has become increasingly dynamic. However, I love the idea of a static generator and being able to bring the website with me wherever I need.

After an epiphany, I bought a new domain: hacdia.sh ๐Ÿ˜ฏ What do you think? Should I move everything there? Sounds interesting.

Moving to a different country during a pandemic

Moving to a different country is never an easy and seamless experience. I moved during a pandemic and this is my experience. Was it worth it?

Hey y’all! I know I’ve been quite silent recently and haven’t even send out my newsletter. I’ve honestly run out of ideas, but I hope I can get back on track with that again soon. Also, next two weeks are exam weeks so I will be busier than usual.

A few days ago, it snowed here in Eindhoven and I was quite happy. I come from a place where it doesn’t snow and even though I’ve seen snow before, it’s not something that is usually part of my life.

Stay safe! ๐Ÿค—

Recently: 2020 Edition

That time of the year has come. It ended and the last digit of the year went up. 2020 was a different year to say the least.

One keeps hearing about some cryptocurrency projects and how people got rich with Bitcoin.

Well, I’m going to try to quickly explain the best I can. First of all, blockchain and cryptocurrencies are not interchangeable. Secondly, “crypto” was historically used to refer to cryptography and not cryptocurrencies. I don’t agree with whoever started this trend.

But somehow I donโ€™t understand the whole purpose behind it and Iโ€™m beginning to suspect that itโ€™s just a pyramid scheme.

Even though I don’t agree with the way Bitcoin works and believe Ethereum is a much better alternative (more on this below), this documentary is fantastic to explain the problems we have nowadays and how Bitcoin (or any other cryptocurrency) can help solving it. Right now, both Bitcoin and Ethereum are based on Proof of Work (PoW). PoW is the mechanism that allows the network to come to a consensus and this mechanism uses a lot of electricity. However, Ethereum is moving to Proof of Stake (PoS), which uses much less energy. Here’s a nice article that quickly explains the differences.

Wouldnโ€™t there be much better ways to exchange money anonymously and uncensored?

How? I’m pretty sure everyone is open to suggestions.

In order to generate any kind of coins, a lot of electricity is used (also from fossil fuels or atomic energy),

True, for now. But that was a choice of Bitcoin, and Ethereum. Ethereum is changing. There’s more cryptocurrencies, obviously, but I’m not aware of how they all work.

until today no project based on cryptocurrencies or the blockchain principle has really caught on

I think the main difficulty is making it easier for the end consumer, and also making the end consumer care. I know countless of people that are aware that many companies have way too much of their data. But do they care? How to make people care? How to make this technologies easy for people to use without all the technical terms, like public and private keys, addresses, etc?

I actually have some notes on blockchain that are not very explained, but there’s so many applications. For example, smart contracts is probably one of my favorites, since they’re trustless contracts. The transaction will happen, no matter what. You don’t need to trust the other party.

Well, I have to go eat breakfast ๐Ÿ˜…Hope I managed to explain something!

Access a network behind a Carrier Grade NAT with Wireguard

Nowadays, a lot of ISPs are putting their clients behind giant NATs which blocks us from easily accessing local services from the outside.

Well… I moved recently and was thinking about setting up a VPN with my new fancy router. But I discovered something: the ISP put behind a giant NAT. Didn’t even know that Carrier Grade NATs were a thing and it never happened to me back in Portugal. Suggestions? I want a simple way to access the network remotely: just for the machines, not for the Internet.

Find visible segments by sweeping

Geometric algorithms can be quite fascinating things. I dive a bit into sweeping line algorithms and how to find visible segments in a plane.

Thanks for noticing the typos. I have considered org-mode for Emacs but I didn’t have time, nor patience to go around it and try it as I should. For now I kept using Hugo and publishing some notes here. I might try in the future.
