200MWh is about 1/100 of Little Boy, the atomic bomb dropped on Hiroshima.

Compressed air can get out all at once given the right circumstances.

Storing energy in a way that can go boom is something I’d be a little scared of, were I a nearby resident. I’m sure thermal batteries can have gnarly failure mechanisms but I would way rather live near one of those than a giant compressed air cylinder.

13, without the pillow, is kinda how babies/toddlers sometimes sleep (once they can roll over).

Resistors.

But once you got that XFree86 config dialed in, life was awesome.

(Ok looks like Xorg has been around for 21 years, so maybe you were running it instead.)

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!)

Slack got me through college on an ancient (even at the time) ThinkPad 600e. Good times!

I had a suite of scripts to log in to the university Linux cluster, download the kernel source and out-of-tree modules (required for the PCMCIA WiFi adapter), compile it, and rsync it back to my laptop.

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.

Maybe not a service in the typical sense, but setting up your router+server to route your home network traffic through a VPN is a fun project.

My router (MikroTik) supports WireGuard, so I can use it with Mullvad for the whole house—but wg is demanding and it’s a slow router, so while it can NAT at ~1Gbps, it can’t do WireGuard at more than ~90Mbps. So, I set up WireGuard/Mullvad on a little SBC with a fast processor, and have my router use that instead. Using policy based routing and/or mangling, I can have different VLANs/subnets/individual hosts selectively routed through the VPN.

It’s a fun exercise, not sure I implemented it in a smart way, but it works :)

I assume you’re referring to the cuckpdate chair.

Whenever I have a Linux box without Internet I just USB tether an Android phone—if the phone is on WiFi then it uses that (not cell), so it’s basically just a WiFi adapter that’s almost universally supported. (I think it NATs, so in some circumstances won’t work, but good enough for most emergency use cases.)

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!

Not the parent you’re responding to, but I think it’s that my “mediocre” comment was a reference to the movie, and yours was a literal response to my joke. A bit of a whoosh situation.

So you’re saying it was…mediocre?

grep -rIi “John.*Cena” dir/

I have this sort of thing aliased, with some added --include flags to filter file type (e.g., only match source/script files). Super useful!

640k 780k ought to be enough for anybody…

I know right? What a poser!

If you can build up intuition around Fourier decomposition I think it gets much easier to understand.

Multiple things going on at the same frequency are indistinguishable (up to a phase). Lots of stuff going on at different frequency can be separated. Light also has frequency (color) and volume (intensity)—it may be more intuitive to conceptualize in this way.

Sadly not really. I use the free tier Oracle, which honestly has worked very well, but I’m not going to recommend using Oracle aside to say that it functionally works for me.

If I were to switch I would probably go to racknerd.
