Do I trust it to do this for me in an automated pipeline? Definitely not.

Will I use this for persisting hand drawn diagrams in the future? Probably yes.

Gemini impressed me today.

I uploaded a picture of my whiteboard and asked it to generate xml for a draw.io diagram based on the image. First in cleaned up the image into something like clipart and then it generated the xml.

Uploading the xml into draw.io worked first time and was 95% correct.

Personally, I hate having to lie to compete.

Sometimes I opt for lies of omission to assuage my conscience.

But we live in a world where many people lie to get ahead, or even just for fun. You’re probably working with people like that already.

Are you that person?
Was it worth it?

Interviewing is a sales meeting.
You’re selling yourself.

Some people lie to sell. It can increase their chances of closing, if they get away with it.

Some people despise lying. These people avoid the risk of being caught but increase the risk of failing to sell.

This is a little more optimistic about AI than I feel, but I like the emphasis of skepticism as a virtue. Optimists often mistake skepticism as pessimism. But we could all use a healthy dose of skepticism to prove out our ideas and help validate our decisions.

On the question of debt When dealing with systems, there are four types of debt that I tend to consider β€” technical (code), evolutionary (value chain), cognitive…

This post by @swardley.bsky.social expresses some of my fear of using AI to code.

It doesn’t just generate tech debt. It generates a debt of understanding. It doesn’t understand the dependencies and consequences. It’s not using reasoning to make good decisions.

Claude Code Agents Are Completely Useless
Claude Code Agents Are Completely Useless YouTube video by Tom Delalande

This is how I feel about most coding agents today.

To be fair, it kinda feels like even with exclusively human authors, most coding projects eventually become an unmaintainable mess.

Agents just get there faster, sometimes before it ever actually works.

Seems like a supply and demand problem.

Vendors used to pay money to be more secure.

Now everything is insecure and finding new vulnerabilities is trivial.

The industry doesn’t need more bug finders. We need more bug fixers, and companies willing to pay for more security.

Reviewing inputs into abstraction layers is pointless if you don’t trust the abstraction layers.

GitOps of infra and platform config is full of lazy half abstraction layers that don’t have schema or tests… multiple layers of them.

Why do we do this to ourselves?

Reddit is overrun by bots and assholes.

Facebook is selling your eyeballs to propagandists.

X is full of nazi fascist pedophiles.

Instagram is full of fake influencers.

TikTok is full of misinformation.

And Bluesky is depressingly real.

Where do you go for good vibes?

Yes, I’ve heard the standard advice:
- Pick your battles
- Collaborate instead of correcting
- Make them think being wrong is their idea by asking questions

How do you tell people they’re wrong when telling people they’re wrong gets you put in the doghouse?

Do you just let them be wrong when you know it’s going to be a problem for you and your team later?
