Didn’t apple used to make their own IR remote for that? Is the hardware onboard the Mini preset to use their hardware or is it more generic once Linux is installed?
Others have some good information here - all I’d like to add to the root is that Windows and Mac have a built-in DNS cache and it’s pretty straightforward to add a DNS cache to systemd distros (if it’s not already installed or in use) using systemd-resolved or dnsmasq if you really dislike systemd. Some distros enable this from install time.
Systems that utilize a DNS cache will keep copies of DNS query results for a period of time, making the application-level name lookup speed essentially 0ms for a cached result. Cold results obviously incur the latency of the DNS server itself.
HLS is a bidirectional protocol though - the system’s total network latency affects how quickly it can change to a new bitrate stream as conditions improve or degrade. And despite the name, it’s not just limited to live content. You can use this to deliver fixed-length content
Not on a flash based motherboard (so basically almost everything recent). On modern systems usually the only thing the battery powers is the clock, which is why they have a separate reset to defaults header/button/switch.
(The CMOS memory of old is replaced with flash memory, al la SD Card or flash drive)
They confirmed that there was a range of CPUs affected by a fabrication issue outside of the press release that went to media. So while we know about the i7/i9, manufacturing process is often shared between different CPU models and with Intel being opaque about what they found it’s hard to understand what actually happened and what’s truly unaffected.

Gonna be honest I did not figure that one out.
I assumed he was part of a hunting party and had been injured separately.
TLDR: probably a lot of people continue using the thing that they know if it just works as long as it works well enough not to be a bother.
Many many years ago when I learned, I think the only ones I found were Apache and IIS. I had a Mac at the time which came pre installed with Apache2, so I learned Apache2 and got okay at it. While by release dates Nginx and HAProxy most definitely existed, I don’t think I came across either in my research. I don’t have any notes from the time because I didn’t take any because I was in high school.
When I started Linux things, I kept using Apache for a while because I knew it. Found Nginx, learned it in a snap because the config is more natural language and hierarchical than Apache’s XMLish monstrosity. Then for the next decade I kept using Nginx whenever I needed a webserver fast because I knew it would work with minimal tinkering.
Now, as of a few years ago, I knew that haproxy, caddy, and traefik all existed. I even tried out Caddy on my homelab reverse proxy server (which has about a dozen applications routed through it), and the first few sites were easy - just let the auto-LetsEncrypt do its job - but once I got to the sites that needed manual TLS (I have both an internal CA and utilize Cloudflare’ origin HTTPS cert), and other special config, Caddy started becoming as cumbersome as my Nginx conf.d directory. At the time, I also didn’t have a way to get software updates easily on my then-CentOS 7 server, so Caddy was okay-enough, but it was back to Nginx with me because it was comparatively easier to manage.
HAProxy is something I’ve added to my repertoire more recently. It took me quite a while and lots of trial and error to figure out the config syntax which is quite different from anything I’d used before (except maybe kinda like Squid, which I had learned not a year prior…), but once it clicked, it clicked. Now I have an internal high availability (+keepalived) load balancer than can handle so many backend servers and do wildcard TLS termination and validate backend TLS certs. I even got LDAP and LDAPS load balancing to AD working on that for services like Gitea that don’t behave well when there’s more than one LDAPS backend server.
So, at some point I’ll get around to converting that everything reverse proxy to HAProxy. But I’ll probably need to deploy another VM or two because the existing one also has a static web server and I’ve been meaning to break up that server’s roles anyways (long ago, it was my everything server before I used VMs).
A static PNG tile database for world.osm is even larger. Without a solid vector tile solution, this is the most efficient data format for disk space.
Also, there’s a post render CDN cache in front of the rendering layer to offset load, plus there’s I think some internal caching in renderd. It’s a pretty complex machine, but databases of the world are in fact huge.
OSM’s core tile servers have dozens of cores, hundreds of GB of RAM each, and the rendering and lookup databases are a few TB. That’s not trivial to self host, especially since one self hosted tile server cannot always keep up with a user flick scrolling.
Edit: car GPS maps and the old TomTom and Garmin devices have significantly less metadata embedded than a modern map.

I work on an open source project in my free time. Officially we support Linux, Windows, and macOS.
I had to change ~2 lines of code to port the Linux/Mac code path to FreeBSD. Windows has a completely different code path for that critical segment because it’s so different compared to the three Unix/Unix-like.
This is a very specific example from a server side code that leaves out a lot of details. One being that we wrote our project with the intent that it would be multi platform by design. Game software is wildly complicated compared to what we do. The point here is that it should be easier to port Unix to Unix-like compared to Unix to Windows.
A well managed server won’t init an arbitrary drive and has a lock screen with a password so that the most a rubber ducky would be able to do is reboot it. Which is something you’d already be able to do if you had access to the front panel with the power button.
You may not but your phone will fail over to data if it loses its lease and stuff like background update tasks will cease to function (like Windows Update or dnf cron)
On/off:
I have 5 main chassis excluding desktops. Prod cluster is all flash, standalone host has one flash array, one spinning rust array, NAS is all spinning rust. I have a big enough server disk array that spinning it up is actually a power sink and the Dell firmware takes a looong time to get all the drives up on reboot.
TLDR: Not off as a matter of day/night, off as a matter of summer/winter for heat.
Winter: all on
Summer:
VMs are a different story. Normally I just turn them on and off as needed regardless of season, though I will typically turn off more of my “optional” VMs to reduce summer workload in addition to powering off the one server. Rough goal is to reduce thermal load as to not kill my AC as quickly which is probably running above its duty cycle to keep up. Physical wise, these servers are virtualized so this on/off load doesn’t cycle the array.
Because all four of my main servers are the same hypervisor (for now, VMware ESXi), VMs can move among the prod cluster to balance load autonomously, and I can move VMs on or off the standalone host by drag-and-drop. When the standalone host is off, I usually move turn it’s VMs off and move them onto the prod cluster so I don’t get daily “backup failure” emails from the NAS.
UPS: Power in my area is pretty stable, but has a few phase hiccups in the summer. (I know it’s a phase hiccup because I mapped out which wall plus are on which phase, confirmed with a multimeter than I’m on two legs of a 3-phase grid hand-off, and watched which devices blip off during an event) For something like a light that will just flicker or a laptop/phone charger that has a high capacitance, such blips are a non issue. Smaller ones can even be eaten by the massive power supplies my Dell servers have. But, my Cisco switches are a bit sensitive to it and tend to sing me the song of their people when the power flickers - aka fan speed 100% boot up whining. Larger blips will also boop the Dell servers, but I don’t usually see breaks more than 3-5m.
Current UPS setup is:
With all that setup, the gauges in the front of the 3 UPSes all show roughly 15-20m run time in summer, and 20-25m in winter. I know one may be lower than displayed because it’s battery is older, but even if it fails and dumps it’s redundant load onto the main newer UPS I’ll still have 7-10m of battery at worst case and that’s all I really need to weather most power related issues at my location.

Jokes aside, I get the classification. I’m pretty solidly in the category of 2c - more tech than some medium business but without the SLA to go with it.
