You either need to quit or keep your head down, I can’t tell which.

This sounds like a constraint I model in my bin packing optimization routine.

Bin packing is theoretically NP Hard but practically solved all the time on real world datasets.

Pro-tip - the older it is, the more likely it is to be good.

This sounds like a broken culture to me. Teams shouldn't tolerate it... it is both harmful and contagious.

A lot of organizations right now are dealing with the "Claude says..." problem. It's not that you should never include any AI generated text in a conversation with other engineers,…

You can just look at the diff when you do a pull request, no prayer needed, and if you want it to be “surgical” in that way, your prompt (and agents.md) can be specific. You can al…

I’m fine with bulk review, it just has to get reviewed before a merge. You don’t need to review the LLM output as you work except as it aids you to work.

LLM editing should be done to produce deterministic output. That is, the LLM should produce a diff, and the user should accept the diff. It seems like a bad pattern to just tell th…

I am familiar with all the particulars, check my HN profile ;)

eBay already had warehousing ops, I assume larger than tcgplayer’s. Last year, eBay shut down tcgplayer’s only fulfillment facility in Rochester, NY and switched to using eBay’s fa…

For my marketplace, I was friends with someone who could make it look like not a ghost town for the supply (an established game store with lots of trading cards in stock). Then, we…

You could argue that compute was a decisive factor in World War II even (used in code breaking and designing nuclear weapons).

We use Mercury’s treasury account to get yields on cash, and what appeals to me is it is easy to manage. I don’t have to worry about setting up processes to move money around and i…

This doesn’t read to me like it was personally written by one person. It’s not Dario we should read this as being written by, it’s Anthropic as an entity.

the shakespeare code tuned a little with different training data does a good job of generating Magic The Gathering commander decks

This is neat, I have a simple CSS effect that I apply to foil cards on my Magic card marketplace site, but I have wondered what it would take to replicate all the different foil ef…

This almost exact thing happened with me with a hiking app I used to make. We had a 7-day trial when you started the app, but we shipped a release that broke this and made all the …

The same could be said for books about writing, like Williams or Strunk and White. The trick is to not apply what you learn indiscriminately.

I find using AI very educational in some respects. I am way more knowledgeable about SQL than I have ever been, because in the past I knew so little I would lean on team members to…

In GIS world, a vector tile is a chunk of geographic data (the vectors) limited to a geographic region (the tile boundaries which fit into the projected checkerboard of your map). …
