Oof, still feeling the muscle aches from the attempted hedge trimming - and I only barely got half way through. Hopefully 500mg of para will take the edge off the aches even if they don't stop my joints from sounding like a badly improvised drum&bass set.

@philpem It's not too bad when you know why they hurt!

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.

penguin42, 22 days ago

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

penguin42, 22 days ago

@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.

@BoscoLab It makes a change from things that won't turn on

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. 😁

@cablespaghetti @fedops Maybe only 36k miles, but the last one was a bit rough :-)

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. #RaspberryPi #RaspberryPiZero

penguin42, 22 days ago

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

penguin42, 22 days ago

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

@adrian erm - is that normal?

I've done about eight straight hours of soldering today, including a bunch of fine pitch rework on things, and I have not been this exhausted in months.

penguin42, 22 days ago

@gsuberland Lovely day for soldering.

200 lines of comments, 964 lines of code, and a complexity of 405 whatever that is.

OK
$ scc apt-pkg/solver3.*

Estimated Cost to Develop (organic) $25,994

I spent like 2 weeks on this, not 3.44 months, and I am 1 person not 0.67.

penguin42, 23 days ago

@juliank That makes you a 10.268x engineer!

brennen, 23 days ago to random

it's true that there are a lot of good songs named after states, but boy are there a lot of songs named after states

penguin42, 23 days ago

@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)
(and I'm a Brit so don't have a state preference)

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.

@attie Reads as a job ad to me; I mean if you can convince them you have some ideas then you can get years out of them not getting there.

gorplop, 24 days ago to random

whoever is running these mirai(?) infection scripts now started to UPX-pack the binaries (I checked just the x86 one so far)

penguin42, 24 days ago

@gorplop What are mpsl and spc?
I guess mpsl could be little endian mips?

penguin42, 24 days ago

@gorplop Oh yeh, makes sense; I'd love to see their stats on architecture spread; MIPS/sh4 and sparc must be pretty rare.

revk, 24 days ago to random

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, 24 days ago

@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...'
