@DaiAoki30 Tomorrow is the single week for waiting my mac app submission 😢

Claude code is down. Got this errors.

API Error: 500 Internal server error. This is a server-side issue, usually temporary — try again in a moment. If it persists, check https://t.co/oy9VJMUTlN.

I found one reason Claude Code can hit 401 auth errors. When /api/oauth/usage is called too often on a schedule, it starts returning 401 just a few hours later. CodexBar seems to use that approach too, so I switched my menu bar widget to read JSONL instead.

It feels like personalized services will move from apps to agents.

But in the end, the ones that survive will probably be services centered on connecting people to each other, or on sharing, not SNS-style sharing, but data sharing.

[John Cho @cr8rcho]

As more information accumulates in llm-wiki, conflicting or contradictory definitions start to appear.

It feels useful for lint checks to also produce a parallel review list of items that should be double-checked by a human.

Not just auto-cleanup, but better surfacing the places where human judgment is still needed.

Wow.. I spent all day yesterday struggling with OpenClaw Chrome CDP, and it turns out it was a 2026.4.12 issue after all.

It’s working normally again in 2026.4.14. Sharing this so no one else has to waste time on it.

The screenshot tool I originally made for myself is slowly getting more and more features.

I think it already covers most of the core things a capture tool should do, and now it can also be used to edit existing image files too.

It’s a free app, so give it a try, and let me know if there’s a feature you want.

If Caps Lock suddenly prints [57358u in the Claude Code terminal, this setting fixes it for now:

"terminal.integrated.enableKittyKeyboardProtocol": false

Most people probably won’t notice any downside in daily use.
Feels like a good temporary workaround until VS Code fixes it properly.

What if consumer Cybercab worked like this?
1. Set personal use hours
2. Set a minimum return time for charging
3. Outside those hours, it goes out and earns money
- Use that income for charging.
- (Only spend it on Tesla products.)

Updated iobook.

When adding bulk transactions, I often paste full rows from Excel, and once the list gets long, checking duplicates manually gets annoying fast.

Now, if an imported item matches an existing transaction by date and amount, iobook flags it as a duplicate automatically.
You can still override it if needed.

Trying to make bulk input a little less painful.

It's been a while since I worked on my Apple Watch app, and it turns out App Group setup and even the default iCloud Sync now work without any issues. Nice!

I've been thinking about something new lately.

I'm building a new app, and until now I've focused on human usability and design. But after spending so much time with AI, I'm now wondering: what if AI uses my app?

Is this obvious? Maybe it's time to consider AI's CRUD operations when building apps.

OpenClaw dashboard showing the old version after updating from Control UI?

The issue: https://t.co/D4ZApdsVPo restarts the gateway via SIGUSR1 but never refreshes the LaunchAgent plist. So OPENCLAW_SERVICE_VERSION stays stale.

This is still an open issue on OpenClaw's GitHub, so here's the workaround:

openclaw gateway install --force
launchctl unload ~/Library/LaunchAgents/ai.openclaw.gateway.plist
launchctl load ~/Library/LaunchAgents/ai.openclaw.gateway.plist

If that doesn't work, openclaw gateway restart as a final step.

Tired of clicking approve every time you run exec commands in OpenClaw Discord? Three simple config changes and you're done:

1. approvals.exec.enabled: false
2. tools.elevated.enabled: false
3. Remove channels.discord.execApprovals

Built owlcode — an open-source CLI bot that gives you remote Claude Code access via Telegram.

Send a message from your phone, get Claude Code's response back. Browse projects with inline buttons, sessions persist across restarts.

npm install -g owlcode

ioshot 1.5.0 is out.

Previously, hover states would disappear when capturing. Now fixed — hover, tooltip, and focus states are all preserved in your screenshot.

Great for design system docs and UI reviews.
Lives in your menu bar, capture with a shortcut. Free.

iobook 1.6.2 is here.

Fixed a bug where custom app icons weren't showing up on iOS versions below 26.

Sorry for missing this on older versions.
Update now and your icons should display properly.

Working on a debit card feature for my finance app based on user feedback. Had to migrate the SwiftData schema — added new fields to Asset and Transaction models.

Wrote up the whole process: VersionedSchema, SchemaMigrationPlan, the typealias pattern that saved me from touching 100+ files, and the pitfalls I ran into.
