This looks sooo sexy, and yet all it is is a power block.

@stsquad @dick_turpin It looks plausible; it's fairly high output, and a nice charge display/power measure - and you can see where the smoke is coming from.
(Good luck on an EMC test)

@dick_turpin Being a tight bastard, I really don't understand how someone spend that much on something so simple.

JEkis, to infosec

I really want to make a career in the field. Security is my passion. I haven't yet decided which role I'd like to get involved in. All I know so far is that Malware Analysis isn't for me. I'm interested to hear from folks in the field who are , have , or both. What roles have been a good fit for you? I'm guessing that Incident Response would be far too high stress, but I could be wrong about that. Boosts appreciated.

@JEkis Be careful to avoid regulated enterprise stuff; there's more box checking than security.

I'm sure there's a shortcut for changing a selection to be what you have yanked elsewhere, it's not ergonomical to do

  • yanking
  • "caw" or similar
  • Hit esc
  • Press P

@penguin42@mastodon.org.uk avatar

@juliank I think there are two ways:

  1. Yank, move to dest, P, then dw to delete the old text.
  2. yank, v for visual mode, select the old text, P, esc to exit visual

@TechConnectify I love the detail on this series, and the historical bits.
I'm kind of curious how much overlap there was between the telephone design engineers and the pinball engineers; things like uniselectors and such all seem similar tech.

For the developers among you:

Documentation/process/stable-kernel-rules.rst[1] now mentions how to tag commits you do not want to see backported to stable/longterm series without an explicit request.[2]

Ohh, and it now mentions the difference between stable@kernel.org and stable@vger.kernel.org, too.[3]

@kernellogger Having two almost identical email addresses, where one is for sensitive information is doomed, there's no way people will get that right. The sensitive one needs to be noticeably different, like stable-sensitive or something.

Because I'm a bit sick at home and don't have enough projects already I started another, albeit small, project. Making a mould to make a mould, to cast some epoxy and to make use of my ZnS:Ag I have here ;-)

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,
@penguin42@mastodon.org.uk avatar

@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.

Iโ€™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 wasnโ€™t getting used. However Iโ€™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. Itโ€™s getting delivered some time in the next few days. ๐Ÿ˜

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

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

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.

@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...'
