It's good the BBC is carrying this article on facial mis-recognition; hardly surprising but good it's not hidden:

I should really chat to the radio folks at EMF to ask about an idea I have involving a really tall telescoping mast pole...

I have an idea for a project which may never end up coming to fruition, but it would be truly ridiculous.

@gsuberland I've still got the 60ft telescoping mast I'm trying to get rid of ....

penguin42,
@penguin42@mastodon.org.uk avatar

@gsuberland It's a Strumech 60ft I believe; so I think it's 3x20ft-ish ; looking at a pic I took before we got it down I think untelescoped only adds a few ft to the total (see https://www.treblig.org/pics/tower/mast-backview.JPG ). It was planted in the garden so relied on the post in concrete rather than guys, and I don't see a guying spec in the manual.
We've got it un-telescoped lying flat at the moment;

Another HP 3325B synthesizer / function generator for repair. Two problems number one: the power switch only turns off the fan. The device itself stays on. Problem two: Fail 021 amplitude too high when calibrating.

I’ve been pretty stressed recently, due to changes at work, being a dad and not really being able to run which is usually how I cope.

I rode motorcycles for years but sold my last in about 2018 as it wasn’t getting used. However I’ve always missed it, could use my own transport and want a bit of a project to distract me.

So this week I bought a lightly crashed BMW R1150RT. It’s getting delivered some time in the next few days. 😁

Tonight on "what the frisk?", a Raspberry Pi device tree overlay that works fine on 32-bit Pi OS, but on a 64-bit Pi Zero 2W it kills the WiFi. I have no idea where to even start figuring this out.

@philpem Mapping something into the address space or IRQs or something related to the wifi?

penguin42,

@philpem Yeh, I don't know how the Pi's connect their wifi; and can't easily find it (!)

@brennen Ignoring the more common ones; I'd give 'California Earthquake' from the Mama's and Papas and 'The Devil goes down to Georgia' from Charley Daniels band. But I've got a whole pile of others (loads of Tennessee ones in Blues)

This is utterly wild... am I a little smooth-brained, or is this totally unrealistic?

  • 200 Mbps compressed to under 1 Mbps
  • Realtime, i.e: ~1ms latency or better
  • Encode and transmit in <10mW (yes, including radio)
  • Lossless
  • High-entropy input

... if you succeed, just email them your solution - no mention of any reward or Nobel Prize nomination.

Some StarTrek banter makes sense...

The constant "logging what you are doing" is something we do in the data centre, via irc, so we know what happened just before shit hit the fan, or we can but in and say "wait!".

But the captain having to say "deploy damage control teams", or "seal off that affected area", or "divert auxiliary power", makes zero sense...

Bugger, over thinking again.

🙂

penguin42,
@penguin42@mastodon.org.uk avatar

@revk It's obviously for legal backup in case of a court martial. 'So Captain, please explain how you lost another starship....well, I did everything by the book, sealed off the affected areas, deployed the damage control teams...'

An easy way to kick off an unattended Linux reinstall:

# kexec --load path/to/kernel --initrd path/to/initramfs --command-line ...  
# systemctl kexec  

No need to set up a PXE server or attach an ISO through a BMC. You can find the kernel, initramfs, and command-line in the installer's network booting documentation.

penguin42,
@penguin42@mastodon.org.uk avatar

@stefanha Oh, yeh that's a neat trick, especially where you don't have control of a working PXE server.

If I'm ever feeling a bout of imposter syndrome, or feel like I've screwed up (e.g. with a bug deployed to production), I like to remember the time that an outsourcing company failed to provide enough security guards for the London Olympics and the gap had to be made up by the Royal Marines and paratroopers.

None of my mistakes have involved the armed forces being deployed.

Is anyone keeping a list of stupid things the Google AI suggests?

Off the top of my head (with additions from replies):

  • Throwing car batteries in the sea (recharges the electric eels)
  • Putting glue in pizza sauce to keep the cheese from falling off
  • Eating rocks for their mineral content
  • "Squat plug" for weight lifting
  • Cooking spaghetti in gasoline
  • Cooking chicken at 38 °C
  • Snake fights at thesis defences

There must be more.

@mansr I guess dropping the thesis on small snakes should work.

Does anyone know why booting a kernel in qemu takes forever to enumerate CPUs in the guest? Example:

[ 0.161515] smp: Bringing up secondary CPUs ...
...
[ 19.231546] smp: Brought up 1 node, 128 CPUs

AMD host, and seemingly scales with ncpus^2 in the host.

@axboe I guess Paolo is probably a good bet to ask? But I guess if your lpj is screwy I guess it's a screwy clock, if you can find which clock...
