As developers, we use databases all the time. But how do they work? In this series, we'll try to answer that question by building our own SQLite-compatible database from scratch. Source code examples will be provided in Rust, but you are encouraged to follow along using your language of choice, as we won't be relying on many language-specific features or libraries. As an introduction, we'll implem

It’s not just you, Next.js is getting harder to use I wrote a blog post the other day about how Next.js Middleware can be useful for working around some of the restrictions imposed by server components. This led to some fun discussions in the world about whether this was a reasonable approach or if Next.js DX was just... bad. From my perspective, Next.js’ App Router has two major problems that mak
The other day I asked what folks on Mastodon find confusing about working in the terminal, and one thing that stood out to me was “editing a command you already typed in”. This really resonated with me: even though entering some text and editing it is a very “basic” task, it took me maybe 15 years of using the terminal every single day to get used to using Ctrl+A to go to the beginning of the line
A possible posthumous artistic depiction of Yasuke, though as you’re about to find out, it also might not be.Few subjects around Japan attract more attention and fascination than the stories of the country’s ancient samurai class. Whether it’s because of their elegant swords, intricate armor, or ideology, there’s undoubtedly something about samurai which has captured the imaginations of countless
I know people will ask, so here they are: SeniorMars’ Dotfiles. Moreover, I will be assuming you are using Neovim 0.10! Improving the (Neo)Vim Experience Although, I stated this was not for beginners, I still need to point out the fundamentals. Without these, I would not consider neovim to even approach the basics of a PDE. If you think this is too basic, then you can skip this section – I promise
A Mini Monitor for a Pi
This post outlines how I used a small 2 inch display as a monitor for my pi. Where it can display tty terminals and X desktops and applications as if it was a normal screen connected over hdmi. My overall goal is to have a sort of handheld “console” that I can connect a keyboard to and use as a normal computer. This post implements the display functionality needed to fulfill part of the goal. I la
A critical review of Marketing Mix Modeling — From hype to reality
Context Most companies spend large chunks of their budget on marketing. Often, without knowing the return of that investment. Marketing Mix Modeling has been promoted as the one method to shed light on the effect of marketing. Not quite coincidentally, this is mainly supported by people that have a self-serving interest to advocate MMM. Opposing standpoints are few and far between. In this post, I

As they say, all good things must come to an end, and so it is with our sponsorship from Red Hat. We recently received notice that after 12 years of support, JRuby funding at Red Hat would conclude. Recent reorganization has changed priorities, and unfortunately there’s no
Foundry competition heats up in three dimensions and with novel technologies as planar scaling benefits diminish.

Inside a 1 dollar radar motion sensor | Maurycy's blog
I recently got some cheap RCWL-0516 microwave motion sensors, mostly because I was wondering how China managed to make a radar for under a dollar: Click for mirrored back view Getting one working was quite easy, I just connected the VIN pin to 5 volts, GND to ground, and added a 1 uF decoupling capacitor on the 3V3 pin. When someone moves within ~5 meters, the OUT pin goes up to 3 volts for 3 seco
How fast is javascript? Simulating 20,000,000 particles The challenge, simulate 1,000,000 particles in plain javascript at 60 fps on a phone using only the cpu. Let’s go. Ok, this is not a particularly difficult challenge if you did all the work on a gpu but the rule of the challenge is to use the CPU only or as much as possible and to stay in js land so no wasm. I know what you are thinking. This

How to think in writing
The reason I've spent so long establishing this rather obvious point [that writing helps you refine your thinking] is that it leads to another that many people will find shocking. If writing down your ideas always makes them more precise and more complete, then no one who hasn't written about a topic has fully formed ideas about it. And someone who never writes has no fully formed ideas about anyt
How To Improve Your Microcopy: UX Writing Tips For Non-UX Writers — Smashing Magazine
Not all companies can afford to hire a full-time UX writer (or are mature enough to consider it yet). As a result, UX writing is often outsourced to team members who may not have sufficient expertise in working with text, such as UX designers and product managers, or to the content or marketing team, who may lack expertise in UX. Meanwhile, interface copy plays a crucial role in the overall user e

The sad state of property-based testing libraries Posted on Jul 2, 2024 Property-based testing is a rare example of academic research that has made it to the mainstream in less than 30 years. Under the slogan “don’t write tests, generate them” property-based testing has gained support from a diverse group of programming language communities. In fact, the Wikipedia page of the original property-bas

Setting the Stage Does this sound familar? You make a change to a library to optimize its performance or clean up technical debt or fix a bug, only to get a bug report: some very large, incomprehensibly opaque test is now failing. Or you add a new compiler optimization with a similar result. Now you have a major debugging job in an unfamiliar code base. What if I told you that a magic wand exists
