San Francisco is taking an interesting approach to this problem: https://www.sfgate.com/bayarea/article/sf-police-wear-flashy-costumes-to-catch-drivers-19769362.php

The only flaw in Corel’s logic was that as soon as you’re running Linux, you lose all desire to run WordPerfect, and develop an irresistible need to align yourself with vim or emacs…

this was always bound to happen as we expand our presence in space.

Yes and no — from a different article:

Radiation associated with Starlink satellites was detected at observing frequencies between 110 and 188 MHz, which is well below the 10.7- 12.7 GHz radio frequencies used for the downlink communication signals.

(The original article said 5M radiation, which should be around 60MHz.)

So Starlink is emitting RF in spectrum where they shouldn’t, which is avoidable, but takes effort.

My guess, and I could be wrong, is that this could be related to something other than the radio(s), such as switching power supplies finding opportunistic structures from which to radiate.

I think you need to include energy cost in the preparation stage. Bread requires a hot oven, which is a real amount of electricity — it’s close to $0.40/kWh where I live. From this link it says that a bread maker uses only .36kWh, but an electric oven would be more like 1.6kWh. So bakita single loaf of bread, you end up with a not insubstantial fraction of the total cost going to heating the oven.

Of course, many bulk foods require heat, so it gets a little sticky this way. Oats/oatmeal probably wins out here, as you can just soak them overnight.

Yeah, “serious” cycling — a sport where a $1k bike barely qualifies as a bike, $5k gets you something rideable, and $10k gets you a pretty decent bike — is so anti-consumer!

(I love cycling, and I’ll defend spending more on my power meter pedels than I would spend on a decent used bike. More bike lanes everywhere please!)

I always say I have a 1969 Wayne Industries Batmobile. Usually a sheepish, “oh, um, we don’t cover that, sorry. click”

Just don’t try plugging it into a Raspberry Pi 5.

No data loss, but won’t work without changing your kernel. The other way around is much worse though — you can use an RPi5 to make a BTRFS drive which essentially only works on RPi5s.

I think (?) it’s generally true that the root user should never mess with users’ files.

Imagine your home directory is shared across many systems on a network (my alma mater did this). It would be really bad if a sysadmin for alpha.university.edu removed a program, and suddenly your personal settings were removed from beta.university.edu — even though that computer still has the program.

This is one of the “UNIX on the desktop” issues — a lot is designed for a sysadmin/multiuser situation, and it has some gotchas when using it as a desktop machine (I’m used to/really appreciate the directory structure and settings management at this point, but it may take some getting used to).

Right, that’s what the & exit is supposed to prevent, since it’s already logged out.

I did all of grad school with i3wm. And I spent a very, very long time in grad school…

I always ran startx & exit to prevent someone from VT switching to a logged in console if my screen was locked :)

Been a while but isn’t that very insecure? Gotta run startx & exit ;)

Any chance you have a DMZ set up on your router?

On your router, are there any settings specific to any host (other than the server maybe)? For example, a static IP or a port forwarded rule.

Do you have a VPN on the phones? Can you traceroute from your phone to the server and post that? (I like PingTools for Android.) You should have 1 hop (you -> server, nothing in between).

Can you verify that you are on the same wifi including same wifi channel? Phone on 5GHz but Linux box on 2.4GHz, for example.

Some mobile clients make it easy to accidentally downvote. I sometimes see that I accidentally downvoted a comment from time to time.

PingTools has been useful for me (though I mostly just use it for iperf).

My username approves.

Quick! Type my username with one finger :)

My username should be a giveaway…

Right, I just meant that you can’t sudo cat file > /dev/sda but you can sudo dd ..., because IO redirection isn’t elevated to root with sudo. I’m not saying anything too profound :)
