Principle Misundertandings by @kevlin.bsky.social at #dddsw #sketchnote

"You can’t change the laws of physics" — unless you’re a SW Eng. with a deadline 😅 In this brilliant talk, @kevlin.bsky.social explores the physical limits behind software, scalability, complexity & why reality always wins in the end. Smart, funny & painfully relatable. 👉 youtu.be/lMZ7I3fQzVs?...

Alright people. I'm creating a new talk for @devoxx.uk next week, and as usual I want your insights into The Real World. If you're using AI as a developer or engineering leader, let me know which fundamentals or "stuff that we've known for ages" are helpful.

When talking about guardrails in the context of LLM instructions, remember that these are not safeguards in an engineering or deterministic sense: they are suggestions that are subsumed into the context of a completion process.

Fancy sharing your recent experiences with 250,000+ software engineers? At Modern Software Engineering, we are all about helping techies be the best they can be by sharing advice, knowledge and learned experience as far and wide as possible. 👇

Umm, no autocorrect, (1) 'burpees' does not need correcting, (2) especially not to 'burgers' 🍔

One of my favourite things that happens is when advertising video screens display errors and this is the best one yet: a giant screen next to the highway showing a windows recovery error

Vulture Culture by Teedy Deigh Did I make it big in cloud computing? No… no, I did not. We were all told having the right cloud strategy was important. Hiring a bunch of meteorologists, however, turned out not to be that strategy. That one was on me. @accuorg.bsky.social accu.org/journals/ove...

Overdue 😍 Post-punk icons Joy Division and New Order have finally received the recognition they deserve: Both bands have been inducted into the Rock & Roll Hall of Fame Class of 2026. After three nominations—the first two of which failed—they've finally made it. #postpunk #joydivision #neworder

Vulture Culture by Teedy Deigh (@accuorg.bsky.social Overload) "Remember all the fuss around the metaverse? Trying to build on an SF trope from the 1980s while pretending that the 1990s and three decades of the Web hadn't happened might not be a solid business plan." accu.org/journals/ove...

That does not look good.

Is it some unwritten law of Teh Internets that proclamations about how "<X> is dead" must be followed by a textbook description of X as the better alternative? "Pastry is dead. Instead, we should bake a dough made from flour, fat, and water"

Nice analysis by @kevlin.bsky.social about being a human using ai coding tools. His focus on the engineering and general principles rather the day-to-day tactics. youtu.be/vpYJMr1pJRY?...

The framing of ADHD in terms of hypercuriosity offers a more perspective than either the clinical 'disability' on the one hand or the overcompensation of 'superpower' on the other. aeon.co/essays/how-t...
