jaxn··on 2x, not 10x: coding with LLMs in 2026
This ignores that non-developers have gone from 0x to 0.5x.
jaxn··on The zero-cost fallacy: open-source software in the agentic era
Yes. Because that is where the intent is/was. In the future, as more changes are made, having the history of the intent is helpful context. And in that back and forth there are also details of what you didn't want, and why. Some of that can be captured in decision docs, etc.

when devs work in isolation, that context/memory is siloed. Same is true when working across platforms (codex, claude, etc).

jaxn··on The zero-cost fallacy: open-source software in the agentic era
they are saying the prompt is the source, the code is the artifact. I think it is a valid comparison. when reviewing a PR, I do want to see the prompt(s) that generated the change.
jaxn··on The Sneakerweb
it’s the wifi hotspot name.
jaxn··on GLM 5.2 and the coming AI margin collapse
though Okta is the first provider working on the enterprise mcp stuff.
jaxn··on Does code cleanliness affect coding agents? A controlled minimal-pair study
agents are pretty good at cleaning up a codebase, finding dead code, fixing bad abstractions, etc. You just have to spend some focusing the agents on that goal.
jaxn··on The Sneakerweb
my cellphone has been named “sneakernet” for years. it’s a throwback to a time when it was faster to walk a zip disk across campus than it was to send it.
jaxn··on Turn your site into a place people can bump into each other
Fun fact. My wife and I met on something similar in 2006 or so. "My Blog Log" was a sidebar widget that showed other people who we reading that blog. She was in marketing, I was in tech, and it was a blog at that intersection written by Rex Hammock (RIP).
jaxn··on Anthropic's open-source framework for AI-powered vulnerability discovery
i have been thinking about this from a different direction: how do we make these shared within a company in a way that increases the productivity floor of the team/department/company. Sure, they can still be extended/enhanced by individuals, but we don’t need everyone configuring mcps, building institutional memory, etc.

for me, it’s not about the cost to leave, it’s about lowering the cost of onboarding and change.

jaxn··on Three Ways to Get Paid (2018)
I think the fourth would be "lie to those who want you to tell the truth".

His father's saying may have been: "There are three honest ways to make a living".

The fourth option is where scams and fraud live.

jaxn··on Waymo pauses Atlanta service as its robotaxis keep driving into floods
Nashville is paused too. I don’t know why.
jaxn··on Was my $48K GPU server worth it?
I assume he is calculating the loss as depreciation - what they would have spent on cloud bills if they hadn’t been doing this locally.
jaxn··on The Claude Code Source Leak: fake tools, frustration regexes, undercover mode
But copilot code review agent is pretty good at catching when code and comments diverge (even in unrelated documentation files).
jaxn··on The Claude Code Source Leak: fake tools, frustration regexes, undercover mode
I didn't even know there was a "three em dash". Bravo.
jaxn··on “Design me a highly resilient database”
i also first thought of point of sale servers
jaxn··on Fontcrafter: Turn Your Handwriting into a Real Font
I used something like this tool to create 10 different fonts of my handwriting. Then I wrote scripts to randomize which font was used for each character, ensuring that no word had that same variant of a single letter. It worked incredibly well for a personalized printed mail campaign. It really did look hand written.

edit: basically what DANmode replied to the same parent. I did this 10 years ago while running for political office.

jaxn··on Labor market impacts of AI: A new measure and early evidence
For some of us, the world has already changed drastically. I am shipping more code, better code, less buggy code WAY faster than ever before. Big systemic changes for the better to our infra as well. There are days where I easily do 2 weeks worth of my best work ever.

I totally understand that not everyone is having that experience. And yet until people live it, it seems they just discount the experience others are having.

I'll take the 12 month bet.

jaxn··on Google Workspace CLI
the LLM writes that too
jaxn··on Ask HN: Do you have any evidence that agentic coding works?
I have a small-ish vertical SaaS that is used heavily by ~700 retail stores. I have enabled our customer success team to fix bugs using GitHub copilot. I approve the PRs, but they have fixed a surprising number of issues.
jaxn··on The Gorman Paradox: Where Are All the AI-Generated Apps?
I have been using AI to remove tech debt faster than ever before.
jaxn··on GPT-5.2
People are confidently incorrect all the time. It is very likely that people will make up plausible sounding answers on StackOverflow.

You and I have both taken time out of our days to write plausible sounding answers that are essentially opposing hallucinations.

jaxn··on Show HN: Data Formulator – interactive AI agents for data analysis (Microsoft)
There are references to using connectors to connect to databases, but I can't find any documentation on how to actually do that.
jaxn··on Public Montessori programs strengthen learning outcomes at lower costs: study
Part of schools "affording" the best teachers is not money, but the amount of discipline problems they need to deal with. Which correlates to the financial status of the families at that school. For tons of reasons.

Which families tend to win the lottery to go to these schools? The parents that can afford to. Even if the school is free, the transportation is often not. Plus the parents have to have enough free time to be aware of the lottery for their 3 year old.

jaxn··on Apps SDK
Google wasn’t always profitable.
jaxn··on Dicing an Onion, the Mathematically Optimal Way
Which is exactly how I was taught to do it while working in kitchens 25 years ago.

The other thing is that this seems to ignore that the onion is round in the other direction too. As far as I can see, it only covers the first dice cut.

jaxn··on Where are vacation homes located in the US?
So, no income tax right when you have less income?
jaxn··on FICO to incorporate buy-now-pay-later loans into credit scores
That is true when you close an account (like paying off the last $10k on a home loan), but I don't think that is correct when paying a credit card down to a $0 balance and leaving it open.

The reason is that your credit score is impacted by both your available credit (higher is better) and credit utilization (lower is better). When you pay of the last of a home loan and close that account, your available credit goes down and your credit utilization goes up (assuming you had any other debt). Both of those hurt you. When you pay the credit card down to $0 and leave it open, your available crediot stays the same and your utilization goes down.

jaxn··on Encryption Is Not a Crime
I believe encryption is the most important 2nd Amendment issue of our time, but I never see it framed that way.
jaxn··on If you get the chance, always run more extra network fiber cabling
Maybe in an apartment. In a house, you want wired backhaul on access points, and wired streaming devices.
jaxn··on Ask HN: Should you reply STOP to unwanted texts?
START works as well. At least for numbers provided by twilio: https://help.twilio.com/articles/223134027-Twilio-support-fo...
