My article about the HN's top bloggers of 2025 is on the front page of HN. Honestly, I'm quite relieved after it flopped yesterday. I don't mind pandering to HN, but it's embarrassing when even that fails.

The underlying data for this is available as CSV files with open CORS headers, so I had some fun loading it into Datasette Lite and querying it with WebAssembly SQLite simonwillison.net/2026/Jan/2/m...

Three years ago I sold my agency to one of our long time clients and went to work for them. I made it 11 months before I got fired. I wrote about the experience, how it felt, and what I took away from it: www.andrewaskins.com/how-to-get-...

From @evanhahn.com "These old books often have passages that lack clarity but overflow with panache. If you like hearing someone described as 'impervious to the shafts of ridicule and insensible to slights,' you’ll like this writing style." evanhahn.com/story-of-the...

I was recently re-reading Crafting Interpreters and was struck by how delightfully effective its introduction is. In just four sentences, @stuffwithstuff.com establishes exactly what you'll learn from the book and why you'll enjoy learning it with him. refactoringenglish.com/blog/craftin...

Law enforcement: we need to break encryption to get access to Signal to protect the children!! Also law enforcement: for years couldn’t catch a pedophile sex trafficker who used email to coordinate all of his pedophile sex trafficking

One of the simplest ways I've improved my writing is deleting words like "very" and "much" that add virtually no meaning.

I've recently been reading an early access version of Refactoring English by @mtlynch.io . I have to say this is a great book, with lots of hard-won tips and advice on how to make your writing more accessible and get it in front of a relevant audience. 

New Podcast Episode: @matt.godbolt.org is back after 5 years! And he's sharing stories about breaking through layers. Sometimes your “disk write” is a network hop in a trench coat, and your “fast path” hides a page fault. Godbolt's rule will help. corecursive.com/godbolt-rule...

Google just suspended SSLMate's Google Cloud account for the third time: www.agwa.name/blog/post/go... The obvious fail is Google's trigger-happy account suspensions, but the more important fail is that Google is disincentivizing the secure options for cross-provider access with Google Cloud. 1/4

Design docs are difficult to write, so if your team can't review them effectively, you're doing most of the hard work but missing out on a huge amount of value.

In my September retrospective, I think about whether to try low-stakes blog posts, share why I doubled my freelancing rates, and whine about how hard it is to send customers an email after they buy my product through Stripe mtlynch.io/retrospectiv...

I started reading software blogs before I got my first programming job 20 years ago. At this point, I’ve read thousands of blog posts and essays about software, but only a small handful stuck in my mind and changed the way I think. refactoringenglish.com/blog/softwar...

This appeared on a web payment form I was filling out. For a second, I thought, "Wait, how are they getting my desktop's local LAN IP?" And then I realized they're just logging their reverse proxy's IP.

In August, I got useful feedback about my book, spent way too long editing a video, and had way too much fun creating the transcript. I also helped a blogger reach #1 on Hacker News and Lobsters when my goal was just the front page. mtlynch.io/retrospectiv...

New achievement: I repaired a CPU with bent pins! I bought a used AMD Ryzen 7 5700G CPU for my home NAS because my old Athlon 3000G was choking on 4K video. The new CPU arrived with bent pins. Thought about returning it but managed to repair it myself with a utility blade.
