2023 X was a better Twitter (for me)

I wouldn't have expected to say this, but X (Twitter) worked well for me in 2023. I got good things out of it. In the previous years, I had a tormentedrelationship with the platform, so, what happened? First, Mastodon happened. Elon Musk's acquisition of Twitter provoked a stampede of the most politically radicalized folks to Mastodon....

When everyone has a say

I don't think creative processes benefit from democracy — quite the opposite. After presenting the new Turbo 8 stuff in Rails World, some people opined that Rails needed to improve collaboration in the frontend space. I got a variant of this question in a couple of podcasts, which also happened when we released Active Record Encryption...

Demo of how page refreshes with morphing work

This article was originally published in the 37signals dev blog. We published a demo showing how Page Refreshes with morphing work in Turbo 8. Comparing code helps a lot in software discussions, so I thought it would be valuable to show how the new feature compares to Turbo stream actions for performing partial updates and broadcasts. ...

The radiating programmer

This article was originally published in the 37signals dev blog. You are an individual contributor at heart. You like writing code and solving technical problems. You dislike meetings and ceremony. Here’s what you can do to maximize what you like and minimize what you don’t: radiate information. The daily standup meetings that Scrum po...

Towards smoother page updates in Turbo

I recently published two articles in the 37signals dev blog related to how we will improve page updates in Turbo 8. • A happier happy path in Turbo with morphing. What we will do. • Exploring server-side diffing in Turbo. An investigation of an alternative approach to fulfill the same vision. I hope you like them!

Navigating personal information with care

This article was originally published in the 37signals dev blog. Accessing personal information from customers is a serious matter. With the launch of HEY in 2020, we developed some technology and processes to support a very simple principle: employees shouldn’t have access — intentionally or unintentionally — to personal information f...

Minding the small stuff in pull request reviews

This article was originally published in the 37signals dev blog. Nitpicking in pull requests reviews means offering insight that looks excessive, pedantic, and unimportant. It’s a pejorative term. I don’t question there are cases where the term applies, but many folks assimilate it to paying attention to the small stuff. By projecting ...

Difficult and complex

There is complex and there is difficult, they are not the same. Being able to run a marathon is very difficult. But what you have to do to prepare is simple. A small sheet of paper is enough to describe the steps. You will need tremendous effort and discipline - so it’s hard - but it is simple. Software development is different: it is ...

Globals, callbacks and other sacrileges

This article was originally published in the 37signals dev blog. Sacrificing purity for convenience is one of the Rails pillars. This principle informs several Rails features that some recommend avoiding but that we happily use in our apps. In this post, I’ll discuss how we use three of those in Basecamp. I’ll show some examples involv...

Let people be

• Have side-projects / don’t have them. • Do open source / don’t do it. • Have tech-related hobbies / have completely unrelated ones. • Have children / don’t have them. • Work long hours / never put in an extra hour. • Small and risky / large and secure. • Work for others / work for yourself. • Work out of passion / work to pay the bil...

Social media evilness (II)

Back in the day, I wrote some notes on the puzzling question of why so many people act so maliciously toward others on social media. A book introduced me to the concept of moral outrage, which brought some answers to my questions. A recent tweet by Dr. Jonathan Shedler referred an article that suggests a pretty different angle: the pri...

Remote struggles

I've worked fully remotely for the last ten years. I find the discussion about remote work fascinating. Is remote better or a lesser evil? Is a decision full of tradeoffs? Something that works in some circumstances, but that is not a good default? As with every complex subject, people – me included – love to reduce it to a dichotomy. A...

Erase and rewind

Imagine a problem you can't understand without solving it first. The first time I saw software development described as a wicked problem was in Code Complete by Steve McConnell, and I haven't seen anything but a constant validation of this proposition throughout my career. And it's a paradoxical one with several counterintuitive coroll...

Energy

Internal energy is tricky. On the one hand, energy is more reliable than happiness. I liked this reflection by Jocko Willink in the Huberman podacast. Everyone experiences joy and sadness as part of their daily lives: keeping a certain energy level is more feasible than a certain level of happiness. On the other hand, as with anything ...

Pending tests

I recently started working on a new thing at 37signals. We have a blank slate in front of us, and nothing is set in stone, which means we are moving fast. I find myself creating meaty pull requests every day. This is how every single pull request I open ends: This is just a reflection of how, most of the time, I write tests at the end....

Sensations

I’m fascinated by the sensations that the things we use induce in us. Not their usefulness, suitability, ergonomics, or aesthetics, but sensations. I don’t have a better term to capture something as substantial as difficult to describe, but I can illustrate with some very personal sensation-driven opinions: • Zelda Breath of the Wild’s...

Writing is thinking

You don’t need an audience to put writing work for yourself: • Writing can let you access things you know but can’t access deliberately. This is a powerful and utterly counter-intuitive insight. • Writing down assorted ideas as they pop up in your mind will bring all the benefits you are looking for here. In my experience, formalities ...

The best presenter ever

I learned about Benjamin Zander in 2011. I was reading Resonate by Nancy Duarte, and she used his Ted Talk from 2008 as a case study in one of the chapters, to illustrate several concepts on how to deliver presentations. Nancy Duarte knows one thing or two about presenting, so her description of him as a "master communicator" caught my...

The augmented programmer

If you are a programmer and have tried ChatGPT, you have probably realized it’s a landscape-changing technology. The history of programming is a history of raising the abstraction level, and with all the cautions and disclaimers you want, the jump that ChatGTP represents is monumental. Right after college, I got a research grant to exp...

Learning with ChatGPT

I’m learning Python these days. The reason is that there are two domains I want to explore and play with — finance and artificial intelligence — and everything I want to use is built in Python. Being Ruby my go-to language, a recurring problem I’ve suffered for years is building my own infrastructure for most things I wanted to do in t...

2022

Some assorted reflections on my 2022: • I wrote a lot, more than ever. This was my favorite piece. This was my biggest hit. And I’m proud of this series, into which I put quite a bit of effort. I had many interesting conversations with people with shared interests, which I enjoyed a lot. I intend to continue writing for myself in 2023....

Stuck

I have referenced this article by Kent Beck in my last twopieces. Here goes the last one. When discussing whether coupling was good or bad, Beck says: “This is where I got stuck for a long time (years).” I can’t think of a more influential author than Kent Beck. His contributions have defined what modern software development is. This s...

Code I like (V): Active Record, nice and blended

This article was originally published in the 37signals dev blog. Persisting objects in relational databases is an intricate problem. Two decades ago, it looked like the ultimate orthogonal problem to solve: abstract persistence out so that programmers don’t have to care about it. Many years later, we can affirm that… it’s not that simp...

Compared to what?

This article was originally published in the 37signals dev blog. I loved this article by Kent Beck on cohesion. At some point, when discussing how cohesion and coupling are opposing forces, it says: “Wait!? Isn’t coupling bad? But cohesion is good? But cohesion is coupling of subelements? Isn’t that bad? And good? This is where I got s...

My curse with plain code editors

I think the first IDE I used was Borland Delphi in 1999. I remember being marveled by its code insight features, where the editor would suggest what properties and methods were available for a given symbol. I remember being puzzled about the programming sorcery powering that — pretty much the same feeling I have today when I play a mod...

What defamation looks like

Last Sunday a friend shared with me this Twitter thread by Kasper Timm Hansen: He confirmed later in the thread he was referring to me as the author of the Vanilla Rails article I recently published in the 37signals dev blog. Kasper starts by presenting a history of friction during PR reviews between us, where he was careful with words...

Code I like (IV): Vanilla Rails is Plenty

This article was originally published in the new 37signals dev blog. Read it there. I have often heard this: vanilla Rails can only get you so far. At some point, apps become unmaintainable, and you need a different approach that brings the missing pieces, because Rails encourages a poor separation of concerns at the architectural leve...

Online discussions, the good parts

Some recent positive experiences made me think about the source of my distaste for online discussions. The blame is on me: I assimilated online to social media or online comments in the wild. I can’t imagine a worse discussion platform than Twitter. Any meaningful discussion requires nuance, which Twitter eliminates by design. Making p...

Code I like (III): Good concerns

Rails concerns have received much criticism over the years. Are they the solution to all the problems or something to avoid at all costs? I think a problem with concerns is that you can use them however you want, so no surprise you can shoot yourself in the foot when doing it. After all, concerns are just Ruby mixins with some syntax s...

Aging programmer

Back in college, they told me that I would start my career writing code, but eventually, I would move to a position where I would ask others to code my designs. To celebrate that this turned out to be completely false, here are some assorted reflections as a 40-year-old programmer that looks back: • Compared to my younger versions, I f...
