I find #Fedimeteo tends to be off a bit on temperature and precipitation amounts here, but pretty accurate on what kind of weather and when

For instance, right now it says it's about three degrees F warmer than it actually is. 🤷

A couple hours ago I checked the forecast, thinking about a ride. @duncan__british_columbia was not very encouraging; basically no chance until about noon - https://ca.fedimeteo.com/duncan__british_columbia/p/1769872477.249978

But Apple's weather disagreed, the rain would taper off in 40 minutes.

I trusted #fedimeteo more. And it is now pouring outside. I will check again in couple hours.

For people in the #UnitedStates:

As US-based #weather models (especially the UFS from NOAA) are becoming less accurate with cuts to funding for scientific research, I’ve added @stefano’s helpful, localized #FediMeteo to my #Mastodon feed. Over the past year I’ve found its Euro-modeled forecasts to be more reliable.

Happy New Year, #FediMeteo friends!

New year, new features! Let’s go step by step:

• Some results for city coordinates were not fully accurate, and forecasts were referring to the center of the administrative area rather than the actual city center. This also affected my own city, with a shift of about 30 km. I have revised the coordinate calculation process and, starting from the next update, the reference point will be the center of the target city. I actually discovered this while implementing the last item on this list...

• In addition to wind speed, FediMeteo will now include an arrow showing wind direction. The direction will also be reported as a value in degrees. This feature has been requested several times in the past, and I think the time has come to introduce it.

• New data added: AQI, the Air Quality Index. Using different indices for each local context would have been complicated, and reporting them all would have made the output unnecessarily complex. For this reason, I chose to use the American AQI for all cities, with a visual indicator to quickly understand the situation at a glance. This is consistent with major weather apps and allows for proper comparisons between different cities. PM2.5 and PM10 values are also included.

Exactly one year ago, on 30th December 2024, I laid the foundation of FediMeteo.

I took a VM, installed FreeBSD, and set up the first jail to support Italy. The goal was to create a tool for my own use, support a few countries, and announce it.

Unexpectedly, the enthusiasm was incredible. That pushed me to keep going, support more countries and cities, and turn it into what it is today.

FediMeteo now supports 38 countries and 2,937 cities, with more than 7,700 followers in the Fediverse alone, not counting the many people who follow via RSS feeds or visit the web pages.

If you are curious to read the story and some technical details, you can find it here:

Today is also Tuesday, a #ThankYouTuesday, so I want to say thanks to:

• OpenMeteo - @openmeteo@fosstodon.org - for providing accurate, high quality data, without which FediMeteo would be far less useful

• @grunfink@comam.es - creator of snac, who made all of this possible using very few resources, on a 4 euro per month VM

• FreeBSD, which thanks to the efficiency of the OS and its jail implementation made it possible to run this service in a stable and efficient way with minimal effort

• FediFollows - @FediFollows@social.growyourown.services - that periodically spreads the word about cities, countries, and the enthusiasm around the project

Here is the CPU usage graph for the last 24 hours of the FediMeteo VM. A full 24 hours, during which a huge number of people are connecting, helped by the traction gained from being among the top stories on Hacker News and Lobsters, as well as the many shares across the Fediverse.

RAM usage? Active, around 450 MB. Then there is cache, ARC, and so on. But in practice, zero swap in use after days of uptime.

39 jails running, 39 snac instances, nginx serving the homepage, and HAProxy. HAProxy caching enabled. ZFS snapshots every 15 minutes, backups via zfs send and receive every hour. The same hourly schedule applies to the recalculation of cities, countries, and followers for the homepage.

All of this on a 4 euro per month FreeBSD VM.

If anyone has doubts about the quality and efficiency of FreeBSD, this is the data to show.

Last year at this time, I was at a nice venue, enjoying a big New Year's Eve dinner and listening to live music, waiting for 2025 to begin.
This year, though, we’re at home, peaceful and relaxed, waiting for my wife to recover her strength after a long bout of the flu.
The common thread? A year ago, I had just set up the 'FediMeteo bot' for automated updates (which, updated and improved, is still running today). And I was planning the announcement date.
This year, I’ve just finished two changes that will further improve the bot and the service.

They’ll go live tomorrow, and I’ll announce them officially! 🙂
