Notes on what I build & learn

[shogo @copilot_shogo]

With Arc Browser shutting down, I'm looking for a new browser to switch to.

Any recommendations for something with a similar vibe? I love Arc's UI, vertical tabs, Spaces, and overall workflow.

Looking for something fast, minimal, and actually enjoyable to use.

What's everyone switching to?

Is anyone else getting a "500 Internal Server Error" on Claude right now?

The status page says all systems are operational, but I keep running into this error.

Is Claude having issues?

[shogo @copilot_shogo]

Another month. Another chance to get closer to the person you promised yourself you’d become.

2026 is almost over, but there’s still time to make a difference.

More discipline.
More progress.
More time spent building the life you want.

The Winter Arc is far from over.

Make these last two months count.

Apple put a touchscreen on a Mac this week. It's not the best part.

I scored all 4 new devices on one scale: screen or brain.
Only one got both, and it isn't the $2,899 MacBook Pro.

It's the $699 iPad mini.

If you want to hear it with the audio, check it out on my Instagram!

Can’t share the audio due to copyright, but Claude Opus 5.5’s motion graphics capabilities are absolutely insane.

Gymshark bringing back Devant from the David Laid era.

Apple bringing back the iconic glowing MacBook logo.

2016 → 2026. A decade later, the icons are making a comeback.

I genuinely love seeing brands bring back the things that made them special in the first place.

2026 nostalgia hits different.

New week. Back-to-back meetings.
Never miss a detail with @PLAUDAI .

Ever since I started taking this, I’ve been able to stay focused and work for 10 hours straight.

[shogo @copilot_shogo]

I just came up with an interesting side hustle idea.

I lined up 6 AI agents that keep working while you sleep: dots, Grok Bot, Muse, OpenClaw, Hermes and MausBot.

I hired 2 for my startup.

Which one would you hire?

[shogo @copilot_shogo]

Major security vulnerabilities have been disclosed in PHP and Node.js.

PHP: Critical (CVSS 9.2), including unauthenticated remote code execution (RCE).

Node.js: High-severity vulnerabilities, including potential RCE.

Security patches are available for both.
If you're running either in production, check your versions and update ASAP.

A little desk setup upgrade.

Aqua Pet, my Aqua pet, just got a new look: Cigarette. My pet grows as I dictate with Aqua Voice. 166,776 words so far. Try Aqua Voice free for a month with my link. https://t.co/PKZsKEQlW1

This whole video is code. No After Effects, no timeline, no keyframes.

Claude Opus 5.5 wrote every scene. I described the motion in plain English, it wrote it as code, and every frame renders as a function of time.

How it was made:
• 9-line voiceover, every animation tied to a word
• 6 scenes, 6 rounds of fixes in plain English
• Slower? Different color? Claude rewrites the math

Does it replace After Effects? Not for everything. For type-driven motion synced to a voice, it already works

I heard Anthropic co-founder @jackclarkSF speak at the University of Tokyo.

His biggest concern: RSI, AI building its own successor. His odds: ~30% by end of 2027, ~60% by end of 2028.

3 things I'm taking away:

1. It starts with code, then moves into science: robotics, biology, real labs.

2. We need a brake pedal. Progress should be visible from outside, checked by third parties, not decided by one company alone.

3. The personal one. He reads first, writes down what he thinks, and only then asks Claude if he got it right. Hand AI everything and you lose your agency.

I'm 22 and I build with AI every day. I'm keeping the thinking part.

Excited to be attending an exclusive in-person session with Jack Clark, co-founder of Anthropic, at the University of Tokyo tomorrow!

The discussion will explore the next decade of AI, from recursive self-improvement to its economic and societal impact.

Grateful to have been selected to attend. Looking forward to hearing his insights on the future of AI!
