FWIW. I've made a couple of essentially duplicate postings across X and Fediverse recently for testing purposes.

Conclusion: I'm pretty sure that engagement on RF/Microwave/Amateur Radio is better here now, and also that there are many more bots on X than real people. I also suspect that followers on X are not seeing much from regular users. Infosec seems reasonably strong in the Fediverse.

There is still a lack of critical mass here in many areas, which is unfortunate. X is close to dead for normal people, but many are still primarily or only present there.

I'm not seeing anything worthwhile on bsky or threads.

What are others seeing re. social media trends? Are blogs making a comeback?

On this week's #HacksterCafe , I interview Emma Fletcher – cofounder of Learn to Solder Kits and Evergreen Support, which helps small #hardware businesses succeed. (Plus, we went to high school together!)

Yes, #systemd switching everything over to #pidfds.

* Most of the internal process tracking is being changed to use PIDFDs instead of PIDs when the kernel supports it, to improve robustness and reliability.

Not sure who needs to hear this but microwave ovens operate at UHF.

The Linux v6.7 merge window has been open for a few days now, here are the SELinux and audit highlights:

So we merged this → https://github.com/systemd/systemd/pull/28891 into systemd today. I like to believe that this is a major step towards closing the "TPM gap" we have on Linux toward other OSes. It can automatically generate an automatic TPM2 PCR policy from various inputs covering the PCRs that generally are hard to predict by the OS vendor, i.e. things like local firmware versions, extension cards and so on. It stores this in an NV index in the TPM. Things like LUKS can then be locked against that NV index.

Working on some long-needed updates to my 1.2m dish setup. Mounting an azimuth sensor (ETS25 absolute encoder) directly under the Az slew drive. A previous belt-driven version was too complicated. This is all upside down, btw. #amateurradio #hamradio #radioastronomy #electronics #microwave

Reminder, the big day starts Monday 8:30. You can still join remotely! @netdev01 0x17 https://netdevconf.info/0x17/pages/sessions.html #netdevconf

@breakingtaps interested in any info here, too.

Video overview of #Incus 0.2 is live now!

Made some millimeter waves today, presumably at 47.088 GHz. Using a Kuhne synth at 11.772 GHz into a WA1MBA quadrupler. I’m able to detect power in this band (6mm), but not frequency (yet). #microwave #mmwave #hamradio #amateurradio.

Ran a full disk threat scan on my Mac with MS Defender ($work requires it), and it found my archive of Linux malware from 1997, and wants to delete it :(

📢 Save the date! The Linux Security Summit North America (LSS-NA) will be held in APRIL 2024, in Seattle, WA, USA.

👉 Note that the CFP is expected to close before the holidays at the end of 2023.

It will be co-located, as usual, with OSS-NA: https://events.linuxfoundation.org/open-source-summit-north-america/

Specific details for LSS-NA to follow soon.

The Kernel Recipes Live Blog is going at full steam #kr2023 https://kernel-recipes.org/en/2023/live-blog-day-1-morning/

Uh oh, I forgot never to fly via CDG.

The 2nd and final day of LSS-EU starting with @mjg59 talking about TPMs and per-process secrets. #linuxsecuritysummit #infosec #linux #opensourcesummit cc. @linuxfoundation

Pro tip ?

We recently added a new document to the systemd website focussing on one specific facet of the service manager: the fdstore. A concept that people should really use more to facilitate "seamless" service restarts and various other things. Please have a look:
