Inspired by Jedda’s Postroll, here is an incomplete list of blog posts that I’ve read and enjoyed in the last 3 months. This list refreshes daily.

The Impact of Digital Authorship by Benjamin Hollon

Like Ben, I also am able to type out faster than I can think. When writing, this turns into a back-and-forth: think for a minute -> quickly type out thoughts -> think again. I also generally context switch between drafting and editing when writing. I’m not entirely convinced that it’s unproductive to do so, but maybe it has to do with the type of writing we’re talking about. For me, when it comes to technical long-form writing, I like to outline via bullet points the concepts I want to hit, and then work towards crafting sentences that meet all those points.

Post-Quantum Cryptography in February 2025 by Jan Schaumann

In my life, I hear smattering of quantum updates. I’m currently studying at a university with a quantum computer, and I’ve worked at IBM’s Thomas J. Watson Research center which houses plenty of quantum research.

As with any up and coming technology, there’s lots of hype and fear regarding it’s widespread use. Luckily, we’re geared as a society to solve technical problems ahead of us. This post, as well as Jan’s from last year, gives a concise overview on the state of quantum computers, the current standards for post-quantum cryptography, and the implementations that exist currently and their roadmaps. Check it out!

Image manipulation with ImageMagick by Sage

I use ImageMagick in my scripts for both compressing the images and extracting out the GPS info for my tracks page. What I didn’t know is that I used the version 6 of these commands which is over 10 years old! I’m now up to date for this decade. Check this post out for other cool things you can use ImageMagick for like making animated GIFs.

Programatic Money by Pierce Freeman

The opinions shared in this piece still hold three years later. For the most part, cryptocurrencies today are too volatile to use as a means of exchange from day-to-day. Additionally, trust and ambiguity are useful features in our society that we should seek to keep and not eliminate. See his post for examples of these claims. The author states that winners in this space will address these issues while also enabling a modern way of handling money. Stablecoins I feel are a step in this direction. They address the volatility issue by pegging to an existing stable asset. They don’t, however, seek to address trust and ambiguity. Imagine the efficiencies we can unlock when we’re able to have trusted actors in the system.

A Friendly Introduction to Container Queries by Josh Comeau

After spending many years writing media queries, it’ll take me some time to adjust to the newer container queries. However, this approach definitely seems more intuitive. Consider defining styling rules based on the container’s size, rather than the entire viewport size.

Building software for connection (#1: Local-First) by Seth Larson

“Concurrency is not needed to feel connected.” In this post, Seth brings up the original Animal Crossing. The game was a multi-player experience, even though you couldn’t play it at the same time as someone else. Instead, it focused on the concept of a “shared space”.

Traditionally for blogs, these shared spaces are comments and guestbooks. My blog in 2025 has webmention support, and I have to say that it brings me joy to see the network of mentions, replies, and likes across the Internet.

Car trouble by Dynomight

I have a similar experience to this piece. One day my car started making a cylic mettalic noise when I was driving. I took my car to the mechanic and it turned out that part of the underbody got bent out of place. The technician bent it back and I went on my merry way.

I agree that it’s easy to overcomplicate things. Especially when it comes to complex technologies like a car. Start simple first, and if needed, work your way into complication.

Smuggling arbitrary data through an emoji by Paul Butler

I heard of watermarking text and zero-width characters before, but this provides a deeper dive (with code!) on how you can hide data in Unicode.

Since this technique relies on variation selectors, you cannot hide a message in any arbitrary unicode character. However, it seems that it works for all the ASCII characters and many emojis. I’m not sure if I would trust hiding it in an emoji though, since new ones are added regularly.

On not taking it personally by Joel Auterson

Commonly, active software projects evolve with time and with the demands of their users. This is different than a lot of creative professions, where outside of preservation techniques, the work stays largely unmodified. Even so, it’s easy to feel an attachment to the coding work we’ve done, and become upset when it’s no longer needed. Joel provides a new perspective in this post. He reminds us that we’re paid to solve problems, and not for the lines of code we write.

Can We Retain the Benefits of Transitive Dependencies Without Undermining Security by Laurence Tratt

As this post describes, the computer process is an excellent abstraction in which programs cannot affect each other. However, we don’t have similar mitigations within the process itself. As more and more of the code that runs an application comes not from the author themselves, but in their dependencies and their dependency’s dependencies; it becomes important for us to know how to prevent a rogue actor from stealing sensitive information. This post presents some potential solutions, and I look forward to seeing how this area progresses.

How does your URL parser handle Unicode? by Daniel Lemire

Specifications exist for many popular data formats and algorithms, but it is up to the implementor to faithfully follow it. Unfortunately, this doesn’t always happen. This post explores the URL parsers that exist in the standard library of many popular programming languages.

Incremental Databases by Chrisman Brown

When I say databases, we normally think of SQL-powered systems such as Postgres/SQLite, or JSON-document based systems like MongoDB. But what if we say that a simple text log can be a database? This post starts from those humble beginnings, to GNU Recutils, to finally SQLite. Before this post, I haven’t heard of GNU Recutils. It allows for your data to be structured with mandatory fields and arbitrary constraints all while being text-based!

Januartuary by Zak

The first of an exciting series of seven posts. Within it, we get a peek at Zak’s life through a daily drawing. Even though it’s summer right now in New Zealand, I always find it crazy to think of seeing luscious green hills when it’s actively snowing where I live right now.

Maximizing Communication, not Traffic by Jeff Kaufman

As a reader of many blogs on the Internet, I imagine that I take inspriration and absorb the styles of others in my own writing. I haven’t really sat down and thought about the intentions others have when writing. However like Jeff, I’m also among the minority that doesn’t monetize their website. Therefore, the tactics that some writers use to captivate attention and increase the amount of time that a reader spends on their website doesn’t necessarily apply to me. It’s a great reminder to be mindful and think about the style of communication that I’m trying to cultivate on this website.

Nobody Gets Fired for Picking JSON, but Maybe They Should? by Miguel Young de la Sota

Wow. From a human-readable standpoint, I enjoyed working with JSON. However, when it comes to using it for inter-process communication, I always felt that it didn’t quite cut it. I mostly thought of this issue in terms of data efficiency, however, it turns out that the problem goes deeper than that. This post shows that since many details are left to the implementors, there are JSON (de)serializers out in the wild today that will result in data loss when parsing integers with more than 16 digits. Some credit cards have more than 16 digits.

Planet Scale by Mark Pitblado

It’s common to measure success by what is quantifiable. For example, a blog post is succesful if it obtains 100 views. Often what ends up happening though, is that the goal posts move. Only 100 views? That’s failure territory, it needs at least 10000 to be successful. The Internet, as interconnected it is, enables this as it’s possible for millions of people to consume your work. Mark reminds us that we don’t need to live life this way. In fact, he notes that often we matter the most to those that are closest to us.

Reverse engineering a car key fob signal (Part 1) by Sami Alaoui Kendil

Many years ago I attempted to decode my keyfob with a friend using GNURadio. We didn’t complete the project, so it’s great to see Sami here write about their experience. I recommend checking it out if you have any interest in RF technologies. The post covers many topics you need to graple such as hardware, modulation, encoding, and cryptographic codes.

This Is Not Your Last Job by Chris Krycho

Well said. Even if your job doesn’t use the technology that you’re interested in, doesn’t mean you shouldn’t pursue it. Your career may end up transitioning beyond your current job, and pursuing your interests creates oppurtunities that may not exist otherwise.

Comments are Back by Matthew Weier O'Phinney

If I am to embed comments on my website, I think I would do it in this exact way. I haven’t heard of the Remark42 commenting system before, but from the looks of it, the system checks all of my requirements as well. Unfortunately at this point, I’m not convinced to have comments on my blog. I really enjoy the emails that my readers send. Maybe some day…

Putting a Dumb Weater Station on the Internet by Colin Cogle

This is exactly the post that tickles my amateur radio spirit. I’ve been curious about the Industrial, Scientific, and Medical (ISM) bands for a while and setting up a weather station seems like a perfect use case! I’ll have to set up rtl_433 on my software-defined radio and see what transmissions are going on in my area. For all I know, someone has already set up a weather station for me :D

Doing dumb stuff with docker and saving containers for offline installs by Dom Corriveau

A nice and simple technique for keeping docker images you care about around, given that you already have a Forejo instance running. I currently sync copies of GitHub repositories I care about, but I haven’t thought to do the same about docker images, linux system packages, etc. Worth thinking about in case there’s an Internet glitch someday, or one of our benevolent corporations decide they don’t want to provide free hosting anymore.

My 18-Months Rule for Open-Source Contributions by Jens Oliver Meiert

It makes a lot of sense to me to close PRs that’s been open for longer than 18 months. If the maintainer ended up wanting to merge the code, likely they will request changes from the author. At that point, the author of the change would have forgotten the context of the codebase and the reasons for their changes. However, I feel that bugs and issues are different. I feel that it’s still important for others to know whether a bug still exists in the software.

Service Reliability Mathematics by Addy Osmani

I haven’t before seen laid out exactly how much downtime each percentage uptime corresponds to for a given year. According to my monitoring service, my website in the last 6 months had 31 minutes of downtime. Extrapolating, this would put me around a 99.99% uptime – Not quite at the five-nines availability. The Wikipedia page on High Availability includes a large table of uptime percentages and how much downtime is permitted by year, quarter, month, week, and day. That and this blog post really gives you an appreciation on the amount of work it takes for our lives to run smoothly.

What are the Rosettas of formal specification? by Hillel Wayne

Back in the day, my favorite program to write when learning a new programming language was estimating pi through a Monte Carlo simulation. Funny enough, I haven’t thought of a Rosetta for formal specification languages. Mainly, I end up following a tutorial to do something standard like common list operations. This is fun to think about, and the article shares some Rosettas for formalizing concurrent systems.

21c/Q2 – new habits for a new quarter-century by Johnny Decimal

I love it when people think big. Instead of only trying to make it to the end of the week, to think about life in years or even quarter-centuries! I resonate with the vision to “check stuff less often”. I did this with checking investments myself; deleted the app from my phone. Unfortunately, however, another habit fills its place. I find it difficult to as Johnny said “embrace boredom.”

Do check out the rest of Johnny’s list though, and think about how you want to live your next quarter-century.

Be aware of the Makefile effect by William Woodruff

There’s too many languages to learn as a developer, and this blog post highlights a byproduct of this. I admit to copy-pasting prior conceptions of Makefiles/CMake build scripts myself.

This is also why I’m extremly hesitant to fully learning new build languages. For example in GithHub actions and Ansible, I call out to external bash scripts that I write by hand. Another separate issue is that I have a slight aversion to introducing build-dependencies. If I determine that the package is performing a task that I can quickly write myself, I often will. That way I’m not trusting yet another software party that I feel I don’t need to.

The Relationship Between Luck and Skill by Lucio

This post explores defining luck and skill in the context of games. I agree with most of the points and intuitions brought up in this blog post, except I don’t believe that “imperfect information” is a necessary component of luck.

For example, consider the heads-tails game. The player tosses a coin and with a 50% probability it will land heads, otherwise tails. The goal is to land as many heads as possible.

If the player tosses the coin 1000 times and each of them land heads, then I would consider the player incredibly lucky. This is regardless of the fact that the player has perfect information regarding the probabilities of each outcome.
