bottombutton··on Ask HN: What are you working on? (June 2026)
I'm finishing a game I started writing before my first daughter was born. The in-laws have been beta testing and they like it so far!

bottombutton··on A Universal Cancer Treatment?
They genetically engineered a kind of bacteria that divides into non-living 'nanocells' that can't multiply further. These cells contain a special kind of RNA and a cell entry mechanism that lets them enter the cancer cells. The RNA interrupts the cell's ability to prepare for division. The article kind of implied that these nanocells follow the bloodstream pathways that cancer cells open when they metastasize.

The researchers main concern was whether those nanoncells would also enter healthy cells, but the tests seem to show healthy cells were not affected.

bottombutton··on How to solve an NP-complete problem in linear time
You might even luck out with those heuristics. Simulated annealing often results in the shortest/best/lowest-energy-state solution by accident.
bottombutton··on A Solution of the P versus NP Problem?
Kind of like proving that you can't solve the halting problem, it lets us put to rest the idea that you can reduce the complexity of NP problems to a deterministic polynomial solution. The collective brainpower can be used to solve other problems.
bottombutton··on Show HN: BotEngine – Easy tool for creating chatbots
I saw a demo recently where someone used Microsoft Bot Framework for what you described. Can't find the video at the moment, but might be worth looking into. [https://dev.botframework.com/]

bottombutton··on Ask HN: Slow engineers, did you get faster? How?
This struck a chord.

[Edit] I had an essay explaining why, but long story short... it's just that I had the same experiences on my old team as you described, so I left out of frustration for what I consider my dream job. Now it feels ruined because I can't really start fresh, and I moved halfway across the country to take this new role. How are we doing on time travel? Any progress?

bottombutton··on Microsoft Shakes Up Its Leadership and Internal Structure
SAP too. Even newer, cloud-based companies like Workday are looking like very promising contenders for the same small/midsize businesses as AX, GP, NAV, and SL.
bottombutton··on Finding topics in Harry Potter using K-Means clustering
This is neat... I love projects like this. When the number of clusters is unknown or hard to predict ahead of time, I'd lean toward something like affinity propagation or mean-shift. Why k-means?
