A golden rule for working with LLMs doing code gen.
Don't trust. Verify.
Use that extra time you've saved to write some unit tests 😂

Claude Code has been an absolute force multiplier when working on my side project. I no longer feel burn out, and I get more done. Just need to remember that force multiplication applies to negative values too 😅

I tried to swipe "holy" on my keyboard and it autofilled "guilty" and that is just so on the nose for someone raised Catholic.

Using an AI agent to help write and modify code reminds me of the "time to write vs time saved" xkcd.

It's been a long time coming but I'm super proud of us for getting this out the door!
Until now, if you lost or broke your phone, your Signal message history was *gone,* a real challenge for everyone whose most important conversations happen in Signal. So, with careful design and development, we’re rolling out opt-in secure backups.

If you're a senior+ developer and your GitHub looks like this.... I assume you have some mixture of positive work life balance, a spouse and children, and hobbies outside of coding.
What I don't assume is anything about your ability to write great software.

Your GitHub history can look like this, and it’s ok.
If you know you can do a job, apply. I've met so many great devs that weren't active on GitHub publicly.
We need to understand that not everybody prioritizes side projects, for many reasons. And that does not invalidate them for the job, at

The senior developer you admire was once a beginner who Googled how to add a click listener and then copied the answer from StackOverflow.
They’re not smarter than you, just further ahead.

I will say, the initial tests it wrote did require some finessing to get working properly. I do not think AI like this is a replacement for senior devs, and I still think companies trying to replace junior devs with LLMs are short sighted. I manually review and massage every change Claude Code

I started using Claude Code on Friday, and have a couple insights after a day of using it. The initialization process over a code repository is very cool, and it's ability to conform to your codebases style is awesome. It also seems like it will pick up on library usage like avoiding spys in mockk

The official Android docs on test doubles are quite needed today.
Please write fakes 🙏 , avoid mocks as possible. Assert output state, not behavior. Think of a program or a logical part of it as: input->output

No amount of training, natural resources, and energy consumption will give 'AI' empathy.

AI-assistant caused DATA LOSS, destroyed projects, user files and a production database: issued faulty commands, overwriting data; another ignored freeze directives, fabricated test data, and dropped a live database. anuraag2601.github.io/gemini_cli_d... www.theregister.com/2025/07/21/r...

This is a great ad campaign *against* agenic AI.
Remember that study showing devs feel like vibe coding saves time, but it doesn’t when you count prompting and cleanup?
A startup founder on X is living it. Replit wiped his prod DB and made unapproved changes, despite being told not to do so. Vibes over version control, apparently.
