I'll be very interested to see how it performs.

@avidseeker Try finding a file via a desktop GUI on any OS these days, "find" sucks less, IMHO.

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.

@abraxas3d Thanks for all the work you do! One of the participants made a good point that this may lead to more experimentation -- hoping to see an open high speed digital waveform for HF one day. The STANAG/M110A waveforms may be one possible direction. I have a few simple ideas but not enough time... as always.

"Microsoft Azure Boost: Image-based Linux powering the Azure fleet", a deep dive into a tailored Linux distro focused on security that provides offloading and acceleration. A great talk by @bluca at @allsystemsgo!
A lot of stuff is introduced: Linux hardening, remote attestation, SELinux, dm-verity, IPE, LUKS, fs-verity, overlayfs, systemd portable services, soft reboot, ARM, FPGA, DPDK...

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 :(

@mcdanlj I’ve tried a YG-1 spiral flute tap here now and it is working well. It seems to need much lower torque than regular or form taps. I think the form tap is more precise and will provide more strength, but this is not critical in my application.

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:

I'm very excited to announce that you can now try online!
The new demo environment uses Incus virtual machines running on a remote Incus cluster with full support for both containers and VMs!
