  • News got you down? The coffee at @yesplzcoffee.bsky.social is always a good pick me up. (The current decaf smells amazing…. )

  • ChatGPT 5 always seems to use “thinking” mode when I ask it stuff. Much more than I would have used the reasoning models for 4o / o3…

  • I’m not sure ChatGPT-5 is really an upgrade.

  • RIP AOL dial-up tones

  • I just learned about the phrase “plot armor”. I’m old.

  • Ugh, openAI is doing cross-session information sharing. This is modestly annoying.

  • See if you can guess which LLM I’m talking about with each picture!

  • The problem with llm vibe coding is you get hidden bombs like this.

       463.               if (numNodes <= 0 || numNodes > 10000000) { // Sanity check
   464                    throw new Error(`Invalid number of nodes: ${numNodes}`);
   465                }

    This easily works with 100m nodes.

  • Wow, I’m probably more aggressive in spending less time at airports than Nate Silver! (And I’ve never actually missed a flight because I’m late – cut it very close to missing bag check deadline one time we were checking bags) His approach is basically what I do. (Target 60 mins pre departure.)

  • Nice to attend my first meeting as a Siam fellow!

  • I knew it! That zoo costume designer is fantastic. Australia Admits All Those Animals Made Up - The Onion

  • Ooh, SIAM news wrote about my talk. Maybe I should record a video on this one! www.siam.org/publicati…

  • Apple needs to fire its advertising team. This is the …4th or 5th major screw up. www.macrumors.com/2025/07/3…

  • Sometimes I try to think of what would it take me to get to yes on something like personalized AI-based pricing as in arstechnica.com/tech-poli… In this case, I’m fine if companies need to disclose lowest price in 6 mo

  • Whenever I hear “AI Tools Did Something Catastrophic”, I just replace “AI Tools” with “Intern” and it sounds just normal! Give an intern unrestricted DB access and you know what to expect!

  • Thanks to @arstechnica for keeping this up (https://arstechnica.com/uncategorized/2002/02/2339-2/) — helped me find the original Google Programming Contest URL (https://web.archive.org/web/20020206161024/http://www.google.com/programming-contest/), not the weird mooglemb.com one.

  • Yellowstone

  • Visiting the badlands at sunset is interesting. Feels like reality has scanlines like on a TV.

  • This was written in 2012 as the worst-case scenario for 2030. info.publicintelligence.net/GlobalTre… Fun to revisit to see what’s still relevant and what isn’t.

  • Seriously, C++ is where Claude code is really hitting its stride for me! This is awesome. No performance wonkiness.

  • Our house kills dehumidifiers so it’ll die before their “smart devices” servers do. bsky.app/profile/x…

  • Claude code makes C++ so awesome. Seriously, if you’ve been a python fan, just dump it and go back to C++. Claude just handles all the BS and you don’t have to worry if you are on some ridiculous fast-path or have an optimized library or … anything. Just good algorithms and performance.
