Still listen to the soundtrack multiple times per month. The best. HACK THE PLANET!
The movie "Hackers" was released 30 years ago today. It still stands as my favorite hacker movie. What is your favorite "Hackers" movie quote? Here are some reasons why it remains my favorite: - The hacker handles suggested by Joey were aliases of real hackers (at the time) -

At this point I’m just switching back and forth between cursor, zed, and clis every single week.

i’ve transitioned to cursor-agent cli so I can switch between models more regularly it’s a nice middle ground
crazy how fast the tables switched from claude code to codex in my experience, both are very good but gpt-5 just being better makes me lean towards codex

I’m amazed by the recent “AI isn’t making a difference” narrative… Is it still a secret that AI is fundamentally changing so much? Goodbill would, quite literally, be out of business by now without AI making us 10-1,000x more efficient. Instead, we are growing like crazy.
Sigh. When I want to read about AI, I don't want to hear how the AI *business* is booming. I want to know if it's actually being helpful and making a difference. Yes, business is booming. Does it help? Apparently not much and not often. This is a strange new world.

My most unpopular opinion is that we’ve already reached AGI and are too stupid to realize it. Today just cements that fact.

When will we see a SOTA coding model that is trained on very hard to find backdoors that litters the world with state-sponsored ways to get into any system? Seems not far away from China trying something like this.

I have an almost 9yo, 5yo, and 4yo. None have a clue what a “YouTuber” is. When does this start?
30% of kids ages 8 to 12 listed “YouTuber” as their top career choice, per WaPo

Ranking most impactful AI coding tools: 1. @DevinAI 2. @zeddotdev + @AnthropicAI 3. @cursor_ai 4. (everything else) Devin has a 10x bigger impact on our business over the rest.

He infected me, too, but I ended up with macOS + AeroSpace + sketchybar. Just the coolest macOS setup I’ve ever had. None of the mess of Linux.
DHH infected me with the Linux bug and now I have a framework laptop with nixos running niri. Living the 90s tinkerer dream. Amazing.
