No. 1970 is 0 in Unix time. The NTP RFC specifies 1900. I had to look it up!

Better to represent it as a 64-bit unsigned fixed-point number, in seconds relative to 0000 UT on 1 January 1900. It’s how he would have wanted it.

In terms of language you are correct. But in terms of SI usage it seems to me OP is expressing it correctly. The SI unit prefixes have a name, a symbol and a multiplier. The prefix is a concept that encompasses all three of those attributes. So “kilo” is one way of identifying the 10^3 unit prefix, but the name kilo is not the prefix itself. It’s just the name we use to refer to it. And the symbol k in km is certainly the unit prefix portion of that unit of measure.

I like LibreOffice Draw for this.

And if you did, and want a fun tech project to track what species are in your yard, check out BirdNET Pi: https://github.com/mcguirepr89/BirdNET-Pi

It can help to download your local map for offline use. The default basemap doesn’t have details like house numbers, but the downloaded maps should.

OsmAnd will do that. If you edit the destinations you can manually specify their order. Click sort there and choose door-to-door to get the most efficient routing.

The app takes some getting used to, but it works very well, and can act as a front-end for contributing to OpenStreetsMap.

See what’s using the space. This will list any dirs using >100MiB:

sudo du -h -d 5 -t 100M /var

I use LibreNMS, which is a fork of Observium. It is primarily SNMP polling, so if you haven’t worked with SNMP before there can be a bit of a learning curve to get it set up. Once you get the basics working it’s pretty easy to add service monitoring, syslog collection, alerting and more. And since it’s SNMP you can monitor network hardware pretty easily as well as servers.

The dashboards aren’t as beautiful as some other options but there is lot to work with.

Interesting. In NC here. Not sure if there’s a difference regionally. I was seeing that kind of RTT on ipv4, but ipv6 was slower. I’ll need to give it another try. The last time I did was at my last place where I had the BGW210. I have the BGW320 now and haven’t tried on that. Maybe that, or changes in their routing since then will make a difference.

Did I read right that it doesn’t use systemd?

AT&T is the same. And the last time I looked they don’t give you enough address space to host your own subnet. You get a /64 instead of a /56. And it’s slower than ipv4.

Every few months I try it out, complain and then switch it off.

Monit works for me. Good basic monitoring solution that can also restart a service/interface.

I also use LibreNMS to do alerting for a variety of conditions (syslog events, sensor conditions, outages and services via nagios). But this is more work to get set up.

I tried draw.io, but ended up liking LibreOffice Draw better for hand-drawing.

If you want to get a live map of the connections on your network you may want to check out netdisco.org or librenms.org. Both are open source network management tools that have mapping.

Obligatory: Debian.

But I’d be tempted to put Proxmox on it and then run containers for each function. Then you get purpose-crafted solutions for each use case, but can easily plug new functions in or shut them down based on what you decide later.

So. Much.

Keep the tv dumb. Don’t connect it to the internet.

I like to check rtings.com for model specs and comparisons. Like, some panel types work well in a bright room, some work better than others when you are watching with a bright light source behind you. The warehouse clubs (Costco, BJ’s, Sam’s) tend to have good deals on midrange tvs.

Then pair it with a streaming stick of your choice. A generic Android TV stick/box would work.

Copy on write is the difference. As I understand it, a btrfs snapshot takes no space when it’s created (beyond the file system record). The filesystem is always writing changes to file chunks as a new copy of the chunk, which is then recorded as a replacement of the old chunk (which is still present on-disk). So a snapshot tracks all of these later changes, and the file system keeps the old file chunks preserved as long as you keep the snapshot. That’s why you can mount a btrfs snapshot. It just shows you the volume through the lens of all of these saved changes.

When you delete a snapshot you are then marking these preserved chunks as free space. So that is also quick.

Monit for simple stuff and daemon restart on failure. LibreNMS for SNMP polling, graphing, logging, & alerting.

Went through a lot of playback apps over the years, and Plexamp is definitely the best of them all. Reliable downloads, good quality, eq settings.
