j_bum··on Claude becomes number one app on the U.S. App Store
Agreed. My wife acts as my North Star for knowing whether tech news is in the mainstream. She doesn’t care about tech.

She said yesterday and Friday her instagram was full of people deleting ChatGPT and downloading/paying for Claude.

It’s definitely beyond the tech bubble.

j_bum··on Show HN: AI Timeline – 171 LLMs from Transformer (2017) to GPT-5.3 (2026)
This is great, I found it much more interesting to view this tree vs. the timeline alone.
j_bum··on “Car Wash” test with 53 models
Claude is so much better for proofing, IMO.

Over the last few years I’ve rotated between OpenAI and Anthropic models on about a 4-5 month cycle. I just started my Anthropic cycle because of my annoyance with the GPT-5.2 verbosity

In four months when opus is annoying me and I forget my grievances with OpenAI’s models and switch back, I’ll report back lol.

j_bum··on Meta's Zuckerberg faces questioning at youth addiction trial
I guess it really depends on what Reddit experience you’re referring to as being no better.

Most Reddit user experiences are probably nothing like HN at all. Give r/all a whirl if you think they’re comparable.

j_bum··on Grandson of Reese's Peanut Butter Cups inventor says Hershey is cutting corners
Thanks for your research, I’m gonna give these a try
j_bum··on Reading and writing can lower dementia risk by almost 40%, study finds
I think the title of this post should be changed to match the “Lifetime cognitive enrichment” from the original publication.
j_bum··on A shortage of tenors
I’d love to play organ with a choir group. But I am not religious, so it feels wrong.
j_bum··on Lessons you will learn living in a snowy place
The pictures show what looks like very powdery snow.

How does this fare with wet and icy snow?

j_bum··on See how many words you have written in Hacker News comments
What were the main attributes that led to varying states of whelmed?

One reason I love text discourse is that it gives me time to thoughtfully respond. My wife is super witty and can be instantly funny and social when she wants. It takes me more time to match that sociable wit.

My hunch is that wit-rate would be a contributing whelm factor.

I'm a scientific software engineer and computational biologist with a PhD in neuroscience. I've built agentic LLM orchestration systems for biomedical workflows, developed open-source bioimage analysis tools (VesselVio, published in Cell Reports Methods), and engineered reproducible analysis infrastructure adopted across biopharma R&D teams. I'm looking for scientific software engineering or ML engineering roles where I can build tools and systems that accelerate scientific discovery.

j_bum··on Why Some People See Collapse Earlier
And what/if any arising issues are you currently tracking?

I’m also curious about your 12/2019 info sources. We had a postdoc in our lab in ~late 01/2020 that was obsessively watching the Johns Hopkins COVID tracker, so that’s when I was tuned into the inbound insanity.

j_bum··on 430k-year-old well-preserved wooden tools are the oldest ever found
We have evidence that non Homo sapiens bipeds (e.g., Neanderthals, Homo habilis) used tools far before we came onto the scene. A long lineage of hominin species came before humans!
j_bum··on Google co-founder reveals that "many" of the new hires do not have a degree
I realize I mistyped, I shouldn’t have said “turn my head to” I mean “ignore” but was being verbose.
j_bum··on Hypnosis with Aphantasia
I’m curious if there is a diagnosis criteria for SDAM.

It likely exists on a spectrum (just like mental imagery).

I have aphantasia and struggle quite strongly with autobiographical memory, but if someone reminds me of an event or I look through old photos, I can remember things.

This is why I love having Immich so much - it lets me feel connected to my past.

j_bum··on Targeted Bets: An alternative approach to the job hunt
What did you put on your resume for that time period? “Sabbatical”?
j_bum··on Google co-founder reveals that "many" of the new hires do not have a degree
Well I am pretty much you but maybe several years junior. I went to a state school, was obsessively focused only on my field of study, and scoffed at the idea of exploring anything else (save for some Jung and Nietzsche).

But as I’m “aging” into the real world after grad school, I’ve similarly realized how silly it was to turn my head to literature.

Curious if you’d be willing to recommend a classic, or share the genres that you’ve been enjoying.

j_bum··on Show HN: Play poker with LLMs, or watch them play against each other
How are these differebt in your mind? The history is the history.

Or do you mean - each agent has a chance to think after every turn?

j_bum··on The first new compass since 1936
Because humans are interesting creatures that do unexpected things.

The cut in the demo (12:18) is very odd and makes me wonder if it’s real.

j_bum··on I program on the subway
Sounds like an incredible period. Do you miss it at all?

I’ve had phases of my life where I was lucky to have periods of absolute and undisturbed focus (grad school, summers during college, etc.). It’s easy to forget how valuable that type of focus time is until it goes away!

j_bum··on Skills Officially Comes to Codex
I have no clue how you’re running your agents or what you’re building, but giving the raw password string to a the model seems dubious?

Otherwise, why not just keep the password in an .env file, and state “grab the password from the .env file” in your Postgres skill?

Wow that’s far more impressive than I expected. I want a laptop with this for programming…

j_bum··on How I use every Claude Code feature
I have AGENTS.md symlinked to CLAUDE.md and it works fine in my repos.

But I can’t speak to it working across OS.

j_bum··on My Impressions of the MacBook Pro M4
Do you think you’ll have any regrets about the nano texture display?

I was torn between nano and regular glass, but opted for the regular glass.

j_bum··on Code like a surgeon
Can you go into a bit more detail on your perspective of the 70s/80s approach vs. today? I’m an analyst with a passion for engineering, but am not an engineer by trade. So honestly I am naive to how now would be different from the past.
j_bum··on Mosquitoes discovered in Iceland for the first time
This travel blog was posted a bit ago on HN [0]. Much of the nature of Greenland was a shock for me to learn about, including the severe mosquitos.
