High frequency is generally bad for transmission line losses, so getting power from A to B is better at lower frequency — DC is a great option here.

If we switched to DC, many things would still flicker though as they would presumably use switching power supplies, but those could be relatively high frequency like you said.

Interestingly, airplanes use 400Hz, as transmission over distance doesn’t matter, and transformers can be made much smaller/lighter.

Never tried it, but hot peppers can be added to birdseed to prevent this — birds aren’t sensitive to capsaicin, so it only affects the mammals.

Gnarly PDEs aren’t exactly the same beast as differentiating single variable polynomials.

Sounds like this was basically the plot of the first Nolan Batman.

Obviously you should use an exponential search, assuming you don’t know the age of the oldest human.

Torvalds uses it too I believe, so you’re in good company (Debian for me, though my heart belongs to Slackware).

VNC? You have your choice of servers, and clients are ubiquitous.

A big gotcha is that you need to be careful with encryption/security, as in classic UNIX style VNC does one thing (remote desktops). It’s easy to forward over ssh though.

You can also use VNC to share, which is not what you want; this depends on the type of server/settings. But you can definitely create a new virtual X11 session and access it remotely.

Not a historian, but folks on The Internet have characterized the Soviet program as a series of milestones, with the US program a series of stepping stones in support of a single goal.

This makes sense with the cartoon, where the Soviets were first in basically everything except walking on the moon.

Not sure how much merit it has, but it’s kinda interesting.

It’s turtles next guys all the way down I guess.

I hate meta as much as the next guy, but according to this they are the #3 organization in terms of kernel contributions, behind only Intel and Red Hat…

I got a lot of problems with you people! And now you’re gonna hear about it!

Resistors.

How does the 2016 slaying of Harambe affect the gorilla bdsm market, and specifically, what’s the impact on Go-spank’s value? Do I need to diversify before 2016, or do I double down?

Sorry for such a newb question.

Per the Linux kernel coding style:

Tabs are 8 characters, and thus indentations are also 8 characters. There are heretic movements that try to make indentations 4 (or even 2!) characters deep, and that is akin to trying to define the value of PI to be 3.

Mac at work. Yabai+sketchybar is no i3wm replacement, but it works ok.

My .zshrc is basically the same as I use on my personal computers, and aside from a few coreutils differences it…kinda just works. I have apt aliased to brew so I can feel more at home.

Stock terminal works fine—I use xterm on Linux, so I’m used to relying on tmux for nice features anyway.

Basically, I miss the window manager, but practically speaking that’s a about it. (I obviously have xscreensaver installed!)

nc is useful. For example: if you have a disk image downloaded on computer A but want to write it to an SD card on computer B, you can run something like

user@B: nc -l 1234 | pv > /dev/$sdcard

And

user@A: nc B.local 1234 < /path/to/image.img

(I may have syntax messed up–also don’t transfer sensitive information this way!)

Similarly, no need to store a compressed file if you’re going to uncompress it as soon as you download it—just pipe wget or curl to tar or xz or whatever.

I once burnt a CD of a Linux ISO by wgeting directly to cdrecord. It was actually kinda useful because it was on a laptop that was running out of HD space. Luckily the University Internet was fast and the CD was successfully burnt :)

I’m a ~/tmp man myself.

I would recommend PoE security cameras. You probably want support for RTSP / ONVIF.

I have some Amcrest cameras talking to Frigate. It is completely local—cameras on a separate VLAN that can’t talk to the Internet, footage is recorded on a server running Frigate. Works very well for me. No vendor lock-in is also nice!

640k 780k ought to be enough for anybody…
