I'm really excited about making Use-After-Free exploits much harder in the #Linux #kernel.

CONFIG_RANDOM_KMALLOC_CACHES has landed:
https://git.kernel.org/linus/3c6152940584

CONFIG_SLAB_VIRTUAL is coming:

The excellent CCC VOC people published the AllSystemsGo! videos from this week. Here's the UKI talk I did there:

Enjoy!

@pid_eins what's stopping you from commuting like this?

Day 2 talks will kick off at 9:45 Berlin-time.
As a reminder, streams for both rooms can be found here: https://streaming.media.ccc.de/asg2023

It's already been 8 years since @LIGO made its first gravitational wave detection! Happy birthday GW150914!

@mcdanlj I'd read that spiral flute taps are weaker and more likely to break for small taps, so I haven't tried them yet. Thanks for the pointers!

The start of the conference is coming very soon! in the meantime we are fine-tuning the last details and we are very very happy to see you again very soon ! #kr2023

Metalwork for the linear amp is going GREAT. First I drilled the wrong hole sizes for the heat sink, then broke two 4-40 taps. Will figure out how to extract these then try a thread forming tap instead of a cutting tap.

Weekend goal: get the metalworking started for the HF/6M amplifier project. kW+ RF deck by W6PQL. #amateurradio #hamradio #electronics #radio #meteorscatter

Anyway, something good -- found a building full of electronics stores in Singapore a couple of weeks ago. So much stuff you don't see on shelves in the US or Australia now, all kinds of niches.

Location is Sim Lim Tower.

You realize that the Fediverse or Threads or bsky could be the new Twitter by next week, right? If a moderate handful of major celebrities and their sponsors got together and jumped to one of these, it would start an avalanche.

@Lee_Holmes This is crazy, even for CVE

There is zero shame in buying preassembled boards, modules, jacks with presoldered wires attached or anything like that. Or kits with all the surface mount work done for you.

There's a lot of great options for constructing things from modules and cable harnesses out there these days, and if it's the easiest way to build the project you're envisioning, go for it!

This is especially true if you are unable to solder or do fine detail work well!

At the end of the day, you still made something, and it's yours.

(Also, if you think I solder all of my own connectors and surface mount stuff, you'd be wrong)

Yes, this is a subtoot based on DMs and conversations that have happened over the past few months where folks have commented to me that they don't feel like they're doing real hardware hacking because they're not designing their own PCBs or soldering every wire or something.

Just go out there and make things!

Troubleshooting a Tek spectrum analyzer PSU. Gonna need a bigger boat. I mean, an ESR meter.
Any recommendations on a budget ESR meter? 🤔

A new batch of Linux Security Summit stickers has arrived! These will be distributed at upcoming conferences, starting with LSS-EU in a few weeks. There's also now a "Europe" 🇪🇺 version of the sticker.

Best meteor scatter rx so far: 1127 km. With just a dipole & preamp on 6m.
