Logic and microcode behind modern CPUs.

New tool in our lab: RF teaching kit from Rohde & Schwarz. It's basically a DUT that contains up/down converter, cal kit, synthesizer, attenuator, bandpass filter, amplifier, mixer, I/Q modulator etc. Used for hands-on training with spectrum analyzer, VNA, and signal generators.

I know I'm a bit late to the party here but the Boltgun devs releasing a free TYPING game to advertise Boltgun 2 is the best bit of Boomshot marketing I've seen in a long time:

🔗 OpenBSD sysadmin flex: # cat /etc/hostname.vlan100 parent em0 vnetid 100 inet 10.0.100.10 255.255.255.0 2 lines. VLAN interface ready. No ip link complexity, no netplan VLAN stanzas, no NetworkManager VLAN profiles. Just elegant simplicity that actually works 🎯 #OpenBSD

if you thought RF was black magic before just know they’re using QR codes as filters now

Lovely hack to pay less to OpenAI when transcribing. Just speed up the audio you send to them.

All a man needs…

to marinate your brain properly in pointer. - you just need to lock in for 2 hours, that's it.

It’s fun to think of programming “costs” in terms of light distance traveled: int -> float conversion: Crosses your Laptop Screen Branch misprediction: Runs your room Thread context switch: 3 Football fields Cache invalidation: Travels to Another city

What is my wifi provider on bro

Was asked for material on universal algebra from a computer science perspective, and i came up with the following suggestions; 'Universal Algebra and Applications in Theoretical Computer Science' by Denecke and Wismath and chapter 3 in 'Handbook of logic in computer science

Interesting use of CN0566 by 2 students from university of Washington: They built a system to generate ISAR images from near-shore maritime vessels (up to 1.8km range, with 0.3m resolution) This was done as part of IEEE radar challenge 2024.

Just. Wow. As we went over Mexico and the U.S. this morning, I caught this sprite. Sprites are TLEs or Transient Luminous Events, that happen above the clouds and are triggered by intense electrical activity in the thunderstorms below. We have a great view above the clouds, so

Responsible parenting ;)

Humans live at 10 bits per second. The brain takes in ~11 million bits per second of sensory data, yet the inner conscious workspace is massively compressed. Most people speak at ~40 b/s. How can we speak faster than we can think? It's all about error correction:

Heads up, wardrivers! Registration for the RF Hackers Sanctuary DEF CON 33 #WWWD opens July 18th - start thinking about where you plan to drive this year!

This is so cool! Thanks!
