“Please clear your cache and cookies or reinstall the app.”
That’s not a fix. That’s tech support karaoke. 😡

Want to accelerate your growth as an engineer? Practice informal leadership.

Don’t wait until you’re handed a title. Don’t wait until you think you’re “senior enough”.

Take action on informal leadership by:
- Volunteering to mentor a teammate through a PR

UX Chronicles: Why Streaming Apps Still Suck
Netflix, Prime Video, and others are failing where it matters most—user experience. Glitches, bad recs, paywalls, endless ads... and execs clearly aren’t using their own products.

When I was on Twitter, I ended up with around 2.5K followers. Now on BlueSky, I have 2K.

Thoughts:
* Number games suck, especially "follower count".
* I do not miss Twitter, at all. BlueSky isn't perfect, but it's much better.
* If you're on Twitter, leave. Seriously.

🚨 .NET devs: Are you checking string prefixes the right way?
One common pattern looks fine… but code analysis says otherwise.
Cleaner intent. Better efficiency. Fewer surprises.
👉 Read the breakdown.
