I just want to point out this guide uses many of the same tasks I use when migrating websites between servers while minimizing downtown.

- reduce dns ttl (if not doing an ip swap)

- rsync website files

- rsync /etc/letsencrypt/ ssl certificates

- copy over database (if writes don't happen often and database is small enough, this can be done without replica, just go read_only during migration)

- test new server by putting new ip in local /etc/hosts

- turn off cron on old server

- convert old server nginx to reverse proxy to new server

- change dns (or ip swap between old and new server)

- turn on cron on new server

France is trying to switch to desktop linux. https://news.ycombinator.com/item?id=47716043 and https://news.ycombinator.com/item?id=47719486

I think AI also makes it easier to deal with issues that come up.

This is a super interesting story and I'm surprised it hasn't made the headline on Hacker News.

Edit: looks like this one is the most popular, from Jan 3rd. It even was put into the 2nd chance pool, but still didn't get catch on: https://news.ycombinator.com/item?id=46472040

Yes, for me I think it was around Nov/Dec 2025, along with harness improvements, and hearing about lots of successes with agenic programming. Having the agent managing its own context and doing the full software engineering loop with writing code, running it, and seeing if it works. That was already there before February 9th.

I think they emailed everyone about this, but I might be wrong. Maybe they only emailed people who actually use copilot.

If you lock your dependencies, it should fail if the hash doesn't match.

uv also has --exclude-newer-package which I think can be used for overriding just a certain package.

New comment by collinmanderson in "So where are all the AI apps?"

collinmanderson — Tue, 24 Mar 2026 16:39:44 +0000

There are more apps, fewer libraries.

You don't need as many libraries when functionality can be vibe-coded.

You don't need help from the open source community when you have an AI agent.

The apps are probably mostly websites and native apps, not necessarily published to PyPI.

"Show HN" has banned vibe-coded apps because there's been so many.

> "Red/green TDD" is apparently the nomenclature

From your link:

> what "red/green" means: the red phase watches the tests fail, then the green phase confirms that they now pass.

> Every good model understands "red/green TDD" as a shorthand for the much longer "use test driven development, write the tests first, confirm that the tests fail before you implement the change that gets them to pass".

New comment by collinmanderson in "Put the zip code first"

collinmanderson — Sun, 08 Mar 2026 02:02:50 +0000

I agree using the preferred city name works just fine for USPS, though maybe not for UPS/Fedex.

What I want to know is: Why isn't this preferred city+state mapping dataset for zip codes publicly available from USPS? It would be like 40kb of data for the entire thing. Why is this not public domain from the US Government?

Edit: or is this what I'm looking for (the "Physical City", "Physical State" columns? https://postalpro.usps.com/ZIP_Locale_Detail

It's missing 00501 at least (which zippopotam has), and military zip codes (which zippopotam doesn't have). Military zip codes are included in this file: https://postalpro.usps.com/areadist_ZIP5

Also fun fact 88888 is for "Operation Santa" uspsoperationsanta.com, which zippopotam is missing, but appears in the areadist_ZIP5 file.

I suspect they have generic SVG drawing that they focus on.

Yes, this is super annoying.

and: '550 (x.x) [x.x.x.x]:xxxx is currently not permitted to relay through this server. Perhaps you have not logged into the pop/imap server in the last 30 minutes or do not have SMTP Authentication turned on in your email client.'

> it could not be more unpopular right now to tell people to stop eating meat

If we phrased it from a carbon perspective that would probably help it be more popular, at least for beef which is a huge methane emitter.

Can you rsync a repo from GitHub?

I consider apt kinds slow. I wish it were much faster.
