Blogging

One of the many reasons I don’t blog regularily is the fact that it is not easy for me to do some necesary preparation tasks:

• cd into content directory
• create a folder
• decide what laguage I want to use (en or pl)
• create a file and add frontmatter or
• use hugo new <path> which is better as it prepopulates frontmatter
• update the frontmatter with description
• use my tool to check what are the tags I used to assign to my posts so that I can reuse them (check go-lista-tagow(pl))

These tasks are tiny but very effective in growing in my mind as “stuff” I need to do first. In order to make hard things easy and build better habits I decided I need to minimize this friction and created a bash script that does this for me, asking questions as I go. And this bash script should be fun to run and use.

This article is the result of me taking notes and trying out basic concurrency concepts presented by Rob Pike in his talk available here: YT video by Rob Pike.

Spawning a goroutine

When you just want to run a goroutine, it does not make the caller wait. The program behaves as if you just spawn a shell command with & at the end.

package main

import (
	"fmt"
	"math/rand"
)

func idea(text string) {
	fmt.Printf("Idea #%d: %s", rand.Int31n(1000), text)
}
func main() {
	go idea("Where is the spring?")
}

We could wait some time for the goroutine to finish:

As a Java senior developer I am always interested in the latest advancements in Java (24). I decided to take a look and summarise what’s happening “at the Edge” of Java.

This release brings a host of new features and improvements that promise to enhance our development experience and push the boundaries of what we can achieve with Java. Each release makes tons and tons of Java tutorials onliny simply deprecated and this is particularily important for those who start to learn java. Perhaps I’m getting old, but the pace makes me feel like I just don’t follow along 👵

I wish you all Merry Christmas!

Jakie zmiany w języku i bibliotece standardowej są warte uwagi? Krótki przewodnik dla zabieganych programistów.

One day when listening to one of Jon Gjengset videos I felt inspired to build something in Rust using https://app.codecrafters.io/catalog page. As a Rust beginner and self-diagnosed ADD thought my inspiration would not last long.

Interestingly, I continued with tasks day by day, slowly making progress till the end (of the beta version available for free). At the moment my interpreter is comfortably sitting in the GitHub repo and you can see the mess I did there.

New tools

I thought I will give a try and install two applications:

• alacritty - terminal emulator - almost 55k (!) stars on GH (I need to find out why)
• zellij - which is a “terminal workspace with batteries included” (hm, why it is so popular?)

In the meantime, I also try out:

• broot - file finder/browser (just checking if I need it, I’m rather happy with fzf defaults.
• yazi - which is ranger alternative written in Rust (“Blazing fast terminal file manager written in Rust, based on async I/O.”)

My playground

• I’m trying out alacritty. Installs without issues on ubuntu with snap. Works just fine. I don’t know why people love alacritty so much.
• I remember I needed to download zellij, but now I found it on snap;
• broot is strange and confusing, I played a little with it, it has its potential, I probably need to learn about it more
• yazi looks nice and promising; it is sooo much faster than ranger (which is witten in Python)
  • however, I need to find out how to change the default configuration of alacritty or yazi so that .png files can be rendered somehow inside the terminal without launching feh or eog
  • (3 mins later) I found this note saying I need to install Uberzug (sounds German and scary, how can people use German unwelcoming names for thei software, I don’t get it.)
• I also enabled Caret Browsing in firefox to improve working with keyboard only.
• I watched “How to useand configure Alacritty” by Eric Murphy
• then The Algorithm just took me over and I started watching, in order:
  • How ThinkPads Became The Internet’s favourite laptop
  • Caring about privacy almost ruined my life.
  • videos about Obsidian Plugins by Christian Lempa

Dopamine levels: through the roof… …wait and calm down! No, you’re not jumping into Obsidian plugins right now! Hold your horses!

Rust - again

I have no idea what is causing that: I am starting to learn Rust for - I think - a third time. Perhaps it is the Youtube bubble in which I’m flowing that is suggesting Rust-related videos; perhaps it is my ADHD brain trying to find something “new” after it got bored with Kubernetes training which took me too long. Whatever the reason, here I am, read to dive in.

The Stoic Developer: Delivering Value with Focus and Serenity

As software developer and contractor, I see the how fast the world changes:

• we’ve barely migrated our codebase from java 8 to java 17 whereas java 23 is going GA in two months time
• we’re constantly prioritizing the releases required to fix vulnerability issues
• other functionalities suffer from tight deadlines
• requirements are evolving “by default” in the “agile process”
• libraries are upgraded, new frameworks are created, software conference videos and podcasts are uploaded
• daily.dev, reddit and hackernews are dangerously pumping up my fomo levels In this whirlwind, it’s easy to feel overwhelmed - it is true for me and for my colleagues in the team: our work can suffer.

Here’s where ancient Stoic philosophy offers a surprisingly potent toolkit.
