Writing more readable parsers in Haskell using keep and skip from elm/parser

The CPS transformer from Chapter 6 of EOPL3 reuses the LETREC language from Chapter 3 with the addition of multiargument procedures and multideclaration letrec expressions. I already wrote a parser for it when I solved exercise 3.33 so I decided to start writing my implementation of the CPS transfor...

VisuaLeaf as a MongoDB Compass Alternative

If you spend some time working with MongoDB, you will inevitably reach a point where collection browsing is no longer enough. At first, everything is fine. You connect, open your collections, run your queries, and look at your data. But as your data grows, so does your need for more control, more c...

What brings you by a conference booth?

I'm thinking about in-person events more and more these days, so I'm curious - what brings you by a conference booth? What's a good experience or design you've seen? Or when do you avoid a booth (or booths!) entirely? LMK 😊

How AI Agent Payments Actually Work — And Where They Break

OpenAI spent months building Instant Checkout — "Buy it in ChatGPT" with Stripe, Etsy, a million Shopify merchants. By March 2026, they pivoted away. Couldn't onboard merchants, couldn't show accurate product data, couldn't handle multi-item carts. They retreated to dedicated retailer apps that redi...

Database Subsetting for PostgreSQL: A Practical Guide (2026)

Every team that has tried to copy production data into a dev environment has hit the same wall: production is too big, full of PII, and growing. The fix is not a bigger laptop or a faster pg_dump. It is database subsetting — extracting a small, self-contained slice of the database instead of all of...

Migrate your Drools rules to OrqueIO DMN

Introduction In a business process, decision-making is essential because it defines the logic that guides the execution of activities. Historically, this logic was externalized into rule engines such as Drools, separating decision-making from orchestration. However, in today’s environment...

What changed after our IVR started pulling data from the CRM

Last year we rebuilt the IVR for a mid-size financial services company. Around 2,500 inbound calls a day, mix of existing customers and new leads, five departments handling everything from account inquiries to collections. The original IVR had been running for three years. It worked. Calls got answ...

Age verification is a mess but we’re doing it anyway

In the span of a few years, age verification went from an idea to standard practice on large parts of the internet. Seeking to prevent kids from accessing porn, other inappropriate content, or social media altogether, laws mandating age-gating have spread rapidly across the globe, reaching the UK, t...

The Cybertruck of e-bikes is here to replace your car

It was at about 36 miles per hour that I decided the Infinite Machine Olto is not a bike. Sure, it has pedals, you don't need a license to ride it in most (but not all!) places in the US, and the folks at Infinite Machine assured me it is allowed in the bike lane. […]

AI Doesn't Fix Weak Engineering. It Just Speeds It Up.

"Weak engineers with AI still produce weak output. Just faster." That was the whole point. AI changes speed. Not judgment. If your team already struggled to make sound architectural decisions, the tool doesn't rescue them. It just helps them make more bad decisions faster. The same gaps. Compressed...

The Setup Is the Strategy: How I Orchestrated a Product Migration with Claude Code

Most engineers using Claude Code are getting a fraction of its value. Not because the tool isn't capable — but because they're using it out of the box, unconfigured, the way you'd use a new IDE without installing extensions or setting up your build system. The default experience is decent. The conf...
