Magnus Numerus

From building a half-adder(1) to dealing with the overflows of life, it has been a ride. Contemplation of my limits about mathematics has stirred a deep seated feeling of hopelessness. It’s working. I chose to study it, because it was fun and made me feel dumb(a.k.a. challenged). Never expected to feel this dumb, though.

To error is human, and to persist is demonic, according to good Augustine. Also, according to him, we are basically irrelevant except to the eyes of Lord. This made me think of the little things, the more mundane things. In this case, numbers.

Si Vanitas

Vanity rules this world. There’s no reason for fancy cars, phones, and many others. Consider the case of NFTs, in which you basically you owned a UUID for some given image, most of the times.

For the uninitiated, a UUID is a Universally Unique IDentifier, which basically means a pseudorandom sequence of characters with a low probability of being repeated in a system. It’s useful for technical reasons, but “owning” something like that is just ridiculous. It’s just a name. It’s like a brand, but less useful.

Fac Vivere

I ought to revisit old half dead projects, and it was so this weekend. Today, a storm hits the coast of my dear country. The weather could be worse, but it’s not a day to be outside. It is not pouring dogs and cats, but the wind is strong and merciless.

My darlings sleep and rest, while I leave the comfort of home for the cafe. It’s half empty and the sun shades float, until one has just flown. There’s some rustle and cries of the desperate workers trying to close them. They worry as it might break inside the glass windows.

Move from jekyll to Hugo

cpmachado@protonmail.com (Carlos Pinto Machado) — Wed, 21 Feb 2024 16:09:50 +0000

Recently I grew weary of my jekyll setup, which previously powered the present blog. The move was surprisingly simple, yet minor adjustments were in order. I’m still looking for a solution for the bibtex plugin I used in jekyll, which I’ve found no serious replacement. It might be a project I’d be interested to take, but time is scarce.

I’ve found Hugo to be less flexible than jekyll’s liquid language, yet powerful as any other. Any open source project can be as flexible as you’re willing to make it, yet, as stated before, time is scarce.

CLI et TUI vivunt

This is not clickbait, I promise. It is however a very trivial article. The title means that CLIs and TUIs live, in Latin. You might ask yourself if this is yet another article on why CLIs and TUIs are great. Is it though?

For the past month, I’ve been looking into Go. A mate talked a lot about it, in early August. It made me consider of what it would be to go back to it.(bad pun, I know)

GitHub cleanup/Paradigm Shift

cpmachado@protonmail.com (Carlos Pinto Machado) — Sun, 30 Jul 2023 14:14:54 +0100

For those who know me personally, it’s not news that life’s been kind of harsh in my twenties. For the last few days I took drastic measures, and start to organize my whole life, with reasonable goals. This sounds crazy as it sounds a completely unreasonable goal from the start.

GitHub and my cleanup #

I’ve been around for years with many different handles, for the other ones I care little nowadays. This one had around 40+ repositories associated with it, spread across different organizations.

Template de latex para a UAb

cpmachado@protonmail.com (Carlos Pinto Machado) — Tue, 06 Jun 2023 16:25:50 +0100

Mal comecei a tirar a Licenciatura de Matemática e Aplicações, na Universidade Aberta(UAb), vi uma necessidade em criar templates de

$$\LaTeX$$

para os meus trabalhos. No decorrer do primeiro semestre, fui desenvolvendo este template, que reside no repositório:

https://github.com/cpmachado/uab-efolio-template

Actualmente suporta tudo o que um estudante de Matemática pode necessitar para cadeiras de 1º ano, excepto no que toca a código. Este é um tema que sempre assombrou, porque nunca gostei das listagens de código. Se tiver uma boa ideia, por amor de Deus, envie um e-mail.

Counting integer divisors

cpmachado@protonmail.com (Carlos Pinto Machado) — Tue, 30 May 2023 18:37:46 +0100

TL&DR: Although I’ve been using Python for years, its set notation still amazes me for its expressiveness. In this case to count integer divisors, given a specific predicate.

Context #

This semester I’m doing a course on Discrete Mathematics. I had an exercise to count integer divisors of a given number, which weren’t divisible by another given number.

To verify my reply, which involved a bit more of analysis, Python enabled me to write a quick script that could do it.

What is happening to my code?

cpmachado@protonmail.com (Carlos Pinto Machado) — Sun, 05 Dec 2021 12:18:09 +0000

TL&DR: Rambling about how my code quality as been consistently decreasing.

Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live.

– John Woods

Background #

My code has consistently been growing dumber over the last year. It might be the symptom of many causes. Nevertheless, it frustrates me a bit.

Like Romero states about coders being artists, I abhor sloppy code, and the one that hurts the most, is my own.
