📖 Early birthday present! Just got The Web Application Hacker’s Handbook 2.

As I work towards becoming a penetration tester, I’m excited to sharpen my web app security skills.

What’s the one book or resource that’s helped you most?

Finally bit the bullet and got myself a Flipper Zero 🐬💥 Been eyeing one forever—can’t wait to see what kind of mischief I can (legally) get up to 👾🔐

I came from Arch, I use Kali in my lab environment. But it’s mostly everything for my field comes default, so 600+ pentesting tools, privacy focused with anonsurf, Tor and firejail and ready for coding with VScode. Also it’s semi rolling release

just switched to Parrot OS and i’m honestly wondering why i didn’t do this sooner 🦜✨
lightweight, privacy-respecting, and packed with tools straight out of the box.

Rooted my spare Pixel 7 Pro and installed Kali Netrunner General — turning it into a mobile pentesting machine. Ready to dive deep and own the network. ⚡📱🔐

In response to your first question, it’s highly unlikely. We all understand the underlying motives this is clearly about the tariffs that have been implemented. That said, it’s still significant news in the tech industry and raises a number of important questions.

NVIDIA’s kicking off Blackwell chip production in Arizona — first time their AI supercomputers are being built in the US.
Looks like they’re finally moving some serious hardware manufacturing stateside. Could shake up the AI game a bit.

Last year, Japan set the internet speed record: 402 terabits per second.
Still fast enough to download the entire Steam library in seconds 🎮⚡

I skipped straight to Vim as it was made the year I was born haha 😅 maybe I should try vi sometime?

Killua Armstrong @armstrongkillua.bsky.social · Apr 12

Thank you 🙏🏻 think it’s time to start doing some actual work now 😅

Wasn’t satisfied with my Arch + Hyprland setup yesterday, so I’ve started ricing it with a nature-inspired Japan theme—clean, calm, minimal 🌿⛩️ Already feels way better. Anyone else gone for a themed setup lately?
