I visited ESA’s antenna laboratory so now you get new wallpapers (for free even!)

@NanoRaptor this is what they took from us

PROGRAMMING TIP
avoid repeating the same 4 lines of code twice by writing 270 lines of beautiful, abstract, generic code

@th @exiliaex amusing:

@g4dbn question on surface RMS for reflectors & horns: do you know if EDM could work for this?

At Microwave Update in BC (https://www.microwaveupdate.org), one of the vendors had a 170 GHz spectrum analyzer. How is it possible in a device this size? #hamradio #microwave #amateuradio

Toured the TRIUMF particle accelerator in Vancouver BC, got to stand on top of a cyclotron. The magnetic field was strong enough to prevent paperclips from laying flat. It’s also where they store old focusing magnets (which become radioactive).

OMG I want to tell you about the coolest thing I've learned about in a hot minute! (Maybe everyone already knows about this, but it's new to me & I LIKE LEARNING STUFF LET'S GO ON A JOURNEY OF EXPLOSIVE DISCOVERY TOGETHER)

SO. Under certain precise conditions, natural deposits of uranium can develop spontaneous nuclear fission chain reactions identical to the kind we make on purpose in modern nuclear reactors

*This has already happened at least once.* About 1.7 billion years ago in Oklo, Gabon

Tweety.

Just like I did for 6.10, I wrote up a "what's new with io_uring" but for the 6.11/12 kernels. 6.11 wasn't super exciting in terms of features, so bundled these into a single page.

Seriously, I only have two DVD/CD drives, both are slot drive and choke on this. It's 2024 and I'm buying a tray-drive.

What am I supposed to do with this? Wrong answers only.

Tomorrow I'll be hosting a Linux Security Modules (LSM) BoF at LPC. If you have any LSM questions or a related topic to discuss, please join us!

Great write-up by @psychomario on a root privilege escalation toolchain which leverages DBus, CUPS, and WPA on Ubuntu: https://snyk.io/blog/abusing-ubuntu-root-privilege-escalation/

@ljs @vegard cardio? Is that a type of pasta?

Free livestream info is here: https://events.linuxfoundation.org/linux-security-summit-europe/attend/live-stream-information/#general

@ksaj the operations that a quantum computer are theorised to perform faster than a classical computer are well understood, so post-quantum cryptography chooses mathematical problems that are known to be hard even for a QC.

https://nap.nationalacademies.org/catalog/25196/quantum-computing-progress-and-prospects is a good and fairly comprehensive introduction to quantum computing for non-physicists :)

Please help us test OpenSSH ahead of the 9.9 release, due in a few weeks.

New features include a new post-quantum key exchange based on ML-KEM, improved controls to disallow unwanted connections and better performance for the existing PQ key exchange.
