Hoo boy...what have I gotten myself into?

Sigh, (work) gmail and its clunky, weak-ass filtering.

My kingdom for a procmailrc.

48-hour average TPD (tacos per day) currently sitting at 5.5. Feeling pretty good about my life choices.

Hot 8 Brass Band was every bit as awesome as expected at the High Dive on Saturday.

@regehr If you're into this kind of heat nerdery and don't already have one, I highly recommend acquiring a thermal camera. Fancy new ones can be kind of pricey, but with a bit of craigslist-watching I snagged a decent-enough used one for <$100 recently.

All sorts of commonplace things are interesting to look at with it, like your "footprints" after walking across a floor barefoot. It's also useful for all sorts of miscellaneous troubleshooting (home, car, electronics...) and taking thoroughly eery photos of your pets.

Realized while making some updates to it that one of my most-used personal programs just turned 10 (as measured from its first commit).

Extrapolating, by 2034 it could in theory have as many as three entire users!

And thus begins day 1 of trapping the wily ion...

@cks @0x0ddc0ffee @drscriptt

In theory I guess you could have the (soft) power switch wired to the BMC as basically a GPIO pin and then the BMC controlling the 'power switch' wired to the PCH or wherever it would go

On the platforms I've developed BMC firmware for that's pretty much exactly how it's arranged. Yes, it's more moving parts between the physical button and actually powering on the host, though often mitigated somewhat by a "GPIO pass-through" feature of popular BMC SoCs (Aspeed parts, at least), wherein you can configure the GPIO controller to basically just bridge two pins together in hardware so there's no software in between and it acts like a direct connection, which can be useful for times when the software that usually manages those GPIOs isn't able to do so for whatever reason (like during the BMC's boot sequence).

Some rocks just don't want to split even after extensive sledgehammering. Fortunately with the right blade a circular saw can make it a little easier.

Also, wow that's by a wide margin the fastest I've ever drained a 4Ah battery (and given that I guess the thermal self-protection shutoff shouldn't have been a surprise).

This week's project: back yard concrete demolition.

Started out with a rotohammer and 42" bolt cutters for the rebar. It...worked, but was very slow going, so I decided to try renting a jackhammer instead.

Found that the jackhammer was sufficiently heavy that setting it down and picking it back up (when switching between it and the crowbar) was a non-negligible fraction of the overall work -- turning the ladder and some scrap 2x4s into an improvised stand for it turned out to be a big win.

I wonder how much energy could be saved globally by web sites not having gratuitous constant background animations burning CPU cycles on every single client that loads the page for as long as they keep the tab open.

(This post inspired by my suddenly-audible CPU fan.)

@cks @mhoye ...except that's still prone to race conditions, because there's a non-zero (brief, but not entirely negligible) window of time between passing the point of no return on deciding to press a key or click a button and actually doing so, and if the focus-theft happens within that window you're still screwed.

I think what I want is "no program can steal input focus ever, period".

@rk @sj Except rmdir(2) is going to fail with ENOTEMPTY, no? You can hold an open fd for an empty directory, but then creating a new file inside it via openat on the directory fd still fails with ENOENT (and similarly if you hold on to it by chdir-ing into it instead of opening it and then creating things in ".").

You could also put secrets in anonyous tempfiles, but at least on Linux other processes could still access it via /proc/$PID/fd.

@rk @mos_8502 In my experience AFS is mostly reasonable to use (modulo Kerberos complications and learning a new permissions system) and from an abstract design standpoint definitely the "nicest", but having once years ago briefly looked into what would be involved in setting up and running it myself I decided it made NFS look comparatively trivial and did not pursue it further.

Realistically, for the kinds of usage I'm picturing from @mos_8502's post, I'd reach for sshfs -- the setup process is basically "run sshd on server, run sshfs on client" and you're done.
