I got into a discussion about monads recently. On a search to find some resources to share, I realized that most essays explained them with type signatures and rules. A missing ingredient to grok them, I think, is to understand the intuition behind them. How could you end up inventing monads?
I get it, you’re too good to vibe code. You’re a senior developer who has been doing this for 20 years and knows the system like the back of your hand. Or maybe you’re the star individual contributor who is the only person who can ever figure out how to solve the hard problems. Or maybe you’re the professor who…
Jujutsu worktrees are very convenient! In git, worktrees are an old concept. The idea is that you can effectively work on your project in 2 different folders …

Though most strings online today follow the Unicode standard (e.g., using UTF-8), the Latin 1 standard is still in widespread inside some systems (such as browsers) as JavaScript strings are often stored as either Latin 1, UTF-8 or UTF-16 internally. Latin 1 captures the first 256 characters from the Unicode standard…

Embrace innovation with Red Hat's cloud solutions for enterprise-wide automation
Over the past year, I've been rewriting large portions of the Middleman codebase to better reflect how I like to write code (as opposed to the silly version of me who did the original version 6 years ago). I've learned a lot since then, spent pretty much every day writing mostly Javascript and trying to find any…

An essay that bids farewell to x87 – a computing architecture too long for this world.
Writing my curriculum in LaTeX was a task that has been on my TODO-list for quite a while. I liked the style of my Word-written CV and I believed it would take hours to come up with a reasonable CV in LaTeX. Nevertheless, I recently sat down, began writing, and after not too long, I ...

A versioned Go command must decide which module versions to use in each build. I call this list of modules and versions for use in a given build the build list . For stable development, today’s build list must also be tomorrow’s build list. But then developers must also be allowed to change the build list: to upgrade…
A rough edge with promises that can sneak up on you.
In 1582, under the inter gravissimas papal bull, the Catholic world transitioned from the Julian Calendar to the Gregorian Calendar . This new calendar shortened the length of the year from 365.25 days to 365.2425 , a reduction of just 0.002% .

A new search engine in 2024? Yes, but stateless — index on S3, serverless — no cluster state, with all Lucene features — filters, autocomplete, facets. And also with local embedding & RAG inference.
Another masterpiece from Bret Victor: The Future of Programming. What you probably don’t know is that his talk was actually an hour long. The second half was censored from the internet by an …
