@reach_vb The official Visualize skill isn't available in codex cli. I did write my own version.

[kurr m @0xkurtca]

@forwarddeploy @console__ @lighthousehq_ Would love to join next one as well!

I have that Davies jersey as well 😂⚽️

@zack_overflow @redabylka_ greenfield stuff much easier just like anything

[kurr m @0xkurtca]

@zack_overflow I even made pane 3 codex to explain implementation codes to me using my pane 0 neovim and asked codex to scroll up and down neovim pane as fit

[kurr m @0xkurtca]

@zack_overflow It’s funny when codex pane utilizes the tmux cli to type “Codex here…” to prompt claude lol.

New blackboard lecture w @reinerpope

How do chips actually work – starting with basic logic gates, and working up to why GPUs, TPUs, FPGAs, and the human brain each look the way they do.

0:00:00 – Building a multiply-accumulate from logic gates
0:16:20 – Muxes and the cost of data movement
0:25:59 – How systolic arrays work
0:39:00 – Clock cycles and pipeline registers
0:51:40 – FPGAs vs ASICs
1:03:14 – Cache vs scratchpad
1:07:16 – Why CPU cores are much bigger than GPU cores
1:11:49 – Brains vs chips
1:15:22 – A GPU is just a bunch of tiny TPUs

Look up Dwarkesh Podcast on YouTube/Spotify/etc to watch. Enjoy!

tmux's superpower is it lets your agents manipulate your terminal sessions:

- read logs from any pane/window
- answer prompts in interactive CLIs
- send keys/clicks into TUIs and capture the screen
- run subagents in separate windows and inspect their output

完全是的！我发现用 Tmux 的一个好处，就是 Coding Agent 会主动使用 tmux capture-pane 去获取别的 tmux window 甚至别的 tmux session 里的内容，从而获得更多的更准确的上下文。

比如：
1. debug 某个后端的错误日志
2. 去跟别的 Coding Agent 的 session 进行联动

这都是 Tmux 自然而然的用��，而且现在的 LLM 都用得很丝滑。

So @loaibassam asked me my stack recently, I replied:

FREE:
Nginx web server on Ubuntu (free)
Auto upgrade with unattended-upgrade (free)
Scheduled workers with Cron (free)
Vanilla PHP for site backend (free)
Vanilla CSS (free)
Vanilla JS for code (free)
Game servers I do in vanilla Node JS (free)
SQLite for DB (free)
Python for tool scripts (free)
Cloudflare with Cloudflare tunnel for DNS/SSL (free)
Tailscale for security (free)
OpenFreeMap for maps (free)

CHEAP:
xAI for AI API (cheap)
Stripe for payments (cheap)
Cloudflare R2 for image storage (cheap)

Hetzner VPS ($4/mo)
Cloudflare domain reg (~$10/year)

So about ~$5/mo total costs with about ~5M unique visitors per month per site (these are site averages)

how the fuck is tailscale free for personal use

[kurr m @0xkurtca]

damn, we are still so early...

[Tibo @thsottiaux]

Happy Tuesday. Codex has hit 4M active users, adding over 1M users in less than two weeks. To celebrate we will reset the rate limits again in a few hours. Enjoy!

[kurr m @0xkurtca]

@raealisa If I want to be picky, the high agency line is generic, could probably scratch that. Maybe writing something very concise but unique point is better.

[kurr m @0xkurtca]

@raealisa Right I was thinking about that. It’s easy to write a long ai sounding paragraph to tell ur life story. But we all have ai reading fatigue now. Better just go straight to the point.

[kurr m @0xkurtca]

@baibaida @fi56622380 Just keep buying $QQQ is my takeaway 😂

[Teng Yan @tengyanAI]

if you use claude code for complex engineering, here are the confirmed workarounds:

type /effort max at session start or set: CLAUDE_CODE_EFFORT_LEVEL=max and: CLAUDE_CODE_DISABLE_ADAPTIVE_THINKING=1

and also..

[Zephyr @zephyr_z9]

why is everything getting leaked and hacked today

[Yuval Adam @yuvadm]

if you don't have these in your configs you're ngmi

[Feross @feross]

🤨 People keep asking how to protect yourself.

#1: set min-release-age=7 in .npmrc

#2: install Socket for GitHub (it's free!) to protect PRs from bad dependencies: https://t.co/D9bsRJj65R

#3: install Socket Firewall (also free!) to protect your laptop: https://t.co/u1NRD57PQ8
