Cheat-sheets: for all EE in Analog audio circuit design - www.patreon.com/posts/cheat-... - github.com/SecondOrderH... [email protected]

for those who haven't been folllowing on chaos.social or facebook (I understand, believe me!). We have been working on our own analog audio designs, from SMT PCBs, soldering & modding clones of classic console pre-amps, EQs and compressors to modding existing gear/kits. check secondorderharmonics.eu

automated testing of PCB manufacture after panelization and PCB production: youtu.be/2zGisPMNstI?...

too much text apparently I've been comparing TRMS Multimeters expensively bought (years ago) and new cheap Chinese, very positively surprised: chaos.social/@azet/115573...

MIT OpenCourseWare has excellent material on Secure Hardware Design (2025 spring): shd.mit.edu/2025/ excellent readings, lectures and materials also labs! amazed.

interesting new findings on DRAM errors related to solar/cosmic rays in large compute environments "DRAM Errors and Cosmic Rays: Space Invaders or Science Fiction?": arxiv.org/html/2407.16...

Calling all makers, breakers & teachers! Workshops are debuting at #BSidesVienna 0x7E9. It’s the first time—your chance to set the tone. CFP is open now. cfp.bsidesvienna.at

ever wondered how to design directed energy weapons with OTC components, cheap china parts? and a custom PCB that we let the MuskAI design & we verify. why not add industrial/rugged components, burst, AM, FM, freq hopping & a epaper status display? 1. x.com/i/grok/share... 2. x.com/i/grok/share...

native load balancing via nftables/netfilter with modulo operations or hashing for distribution (supports "maps" [changable definitions pointed to by rules] for bigger setups): wiki.nftables.org/wiki-nftable...

netfilter connection tracking in detail for the uninitiated, from a usenix login article (2006 but nevertheless current): people.netfilter.org/pablo/docs/l...

It begins! On November 22nd, 2025, #BSidesVienna is back at Urania Sternwarte. Fresh insights, familiar faces, and the same legendary venue. More to come—stay tuned. bsidesvienna.at/venue/

how.complexsystems.fail great read!

did you know NASA maintains it's own cryptography library for space up/down link and telemetry among other things? it's used with the core flight system for example. github.com/nasa/CryptoL...

merged recent book additions with a better place for sunlight for plants on a shelf left over by the previous occupant. happy books, happy plants, happy partner. :)

there's yet another stupid proposal - this time for debugging not middle box vendors - in the TLS working group to standardize key export among other encrypted traffic details. please don't. cryptolibs provide these & we all know how to handle wireshark. mailarchive.ietf.org/arch/msg/tls...

Breaking RSA with Overclocking-induced GPU Faults: ia.cr/2025/145

A Robust Variant of ChaCha20-Poly1305: ia.cr/2025/222 "We present a new nonce-misuse resistant and key-committing authenticated encryption scheme, called ChaCha20-Poly1305-PSIV, that is based on carefully combining the ChaCha20-Poly1305 [...] into the NSIV paradigm [...] without performance loss."

TIL: so many tuns, tons, tonnes! "Recent specialized uses include the ton as a means of truck classification. It can also be used as a unit of energy, or in refrigeration as a unit of power, sometimes called a ton of refrigeration." see also: en.wikipedia.org/wiki/Ton_of_...

the bandwidths for AI/ML workloads in cloud datacenters are unbelievable. Petabit/s+ per Rack, so 64x200G switch optics don't do the job anymore - naturally they started building on-die high-density WDM with 10Tbit/s: 64λ@200G per fiber www.youtube.com/watch?v=mrl8...

jemand hatte wohl spass mit fefe's blog software (nope, lese die schrecklichen balkonmuppet beitraege & "gesellschaftskritik" selbst nicht - kam per msg) und einen bug gefunden, war wohl zu secure! besser nochmal mit C drueber schreiben das ganze, inline __asm__ fuer AVX koennte es vmtl optimieren.

amazing talk on TCP stack fuzzing by the great illja: www.youtube.com/watch?v=DobI...

Only a couple of days left till #BSidesVienna! Please be sure to return your tickets if your are not able to visit the event on the November 23. There are many people on the waiting list, do not let a ticket go to waste please. Thanks!

A long time ago in a hacker space far far away... 
@bsidesvienna.at is on again soon and the t-shirt design is epic. See you there 23/11/2024 @ Urania. Check the website for all the Infos.
