jebarker··on Evidence of inconsistencies in evaluation process and selection of winners
Ego is also at play here. In inherently competitive fields like academic science using LLMs to get results more quickly is an alluring siren.
jebarker··on Old and new apps, via modern coding agents
What makes this a hobby project? He’s a university professor so developing teaching material is part of his job.
jebarker··on FAANG Simulator
I know many, many people that have continued to increase their expenses as their income grows but would also like to FIRE in theory. There’s a whole movement called FatFIRE that is basically full of these people
jebarker··on FAANG Simulator
I don’t doubt it’s possible, but suggesting that the game isn’t simulating FIRE because it includes lifestyle inflation seems wrong.
jebarker··on FAANG Simulator
Are you suggesting that everyone with FIRE aspirations avoids lifestyle creep?
jebarker··on Reflections on the Guillotine (1957)
Exactly, it’s about the choice of word but I don’t think it’s meaningless semantics.
jebarker··on Reflections on the Guillotine (1957)
No, we don’t agree it’s “deserved” in any cases. I agree in the self defense case it’s justifiable based on near certainty about the outcome if you don’t respond with lethal force. That has nothing to do with “deserved”, which is always subjective unless we discover some universal moral code we’re all bound to abide by. So I think where we agree is that it’s all opinion.
jebarker··on Reflections on the Guillotine (1957)
I don’t find this a convincing argument. This works as an argument for permitting lethal force to end a life-threatening attack. But once someone is already detained there’s no way that killing them meaningfully increases public protection over just keeping them locked up.
jebarker··on Reflections on the Guillotine (1957)
How do you define “deserve” in any kind of objective way?
jebarker··on CarPlay Is Additive
As far as I’m aware there is no native Pandora app, just TuneIn for internet radio. Do for Pandora you’d have to stream from a phone via Bluetooth.
jebarker··on CarPlay Is Additive
As an R1S owner I feel like the elephant in the room is that the Rivian developed infotainment software is just not very good. For example, the Spotify app has weird scrolling issues and the interface for offline downloads is clunky and unreliable. The maps/route planning is fine but not really any better than Apple/Google Maps (or ABRP). So I find it hard to give much credit to their argument against CarPlay when they’re not providing a better experience via their native apps.
jebarker··on Show HN: I Derived a Pancake
This works with dairy-free milk too. My daughter has a dairy allergy and figuring out we could turn pea milk into pea buttermilk with a tbsp of white vinegar upped her pancake experience significantly.
jebarker··on Making peace with your unlived dreams (2023)
This is so true. A few years ago I was volunteering at a running race that’s very hard to get into and many people have as a life dream. I found it kind of amusing how many people were having pity parties in the latter stages of the race despite having dreamed of getting into it for years, maybe decades.
jebarker··on I am retiring from tech to live offline
Thanks for the great answer and practical steps involved in the transition.
jebarker··on I am retiring from tech to live offline
How did you transition from tech to teaching?
jebarker··on I am retiring from tech to live offline
What does it even mean to say you want to build something but you don’t know what it is?
jebarker··on Dispatches from the possibly last days of human relevance
I think it depends what they’re hoping to get out of it.
jebarker··on Ferrari Luce
Imagine being able to afford a Ferrari and then buying the one that looks like a fancy Prius
jebarker··on How diamonds are made
It’s kind of surprising that diamonds still have appeal as jewelry at all given the rise of lab-grown. I always assumed that people liked them because they were rare and expensive.
jebarker··on We've made the world too complicated
AlphaFold has a shared technical ancestry with LLMs and many people believe that was a truly significant advancement of science that may lead to benefits for humanity and the planet. I don't think this was a one-off fluke, strongly generalizing pattern matchers will be useful in many areas of science even if LLMs turn out to be overblown.
jebarker··on What's a Mathematician to Do?
By having a job. If that job is the same as your intellectual/artistic pursuit then you have to balance the needs of satisfying your employer and what keeps your motivation going over the long term. All I’m saying is that worrying too much about future achievement or “great contributions” are a recipe for burnout and disappointment.
jebarker··on What's a mathematician to do? (2010)
“Comparison is the thief of joy.”

Do the math because you enjoy doing the math and if you do it long enough you may well do something of value to someone else. Same goes for most intellectual and artistic pursuits I think.

I’ve learned for myself that as soon as enjoyment is based on some future achievement or ranking my work against others the day to day satisfaction dries up.

jebarker··on Pulitzer Prize Winners 2026
I’ve been gradually reading prior Pulitzer winners for fiction and I have to say I haven’t hit a bad one yet. Maybe I’ll try and read this years before it’s several decades old.
jebarker··on For thirty years I programmed with Phish on, every day
> the actual engineering

I was with you until the last three words. Craftsmanship in writing code is also “actual engineering”, it’s just not the engineering that people will pay a human to do now.

jebarker··on Ask HN: Is the Job Market Actually Bad?
Retire earlier?
jebarker··on A Dumb Introduction to Z3 (2025)
I wonder how often interviewers object to the approach of solving their dynamic programming problem using a constraint solver?
jebarker··on I run multiple $10K MRR companies on a $20/month tech stack
What has your career looked like? I'm interested because I've spent 20 years in applied research and I've only more recently realized the continual stress that I've felt for 20 years from trying (and mostly failing) to innovate in the "what to build" space.
jebarker··on Improving my focus by giving up my big monitor
I find it useful to have multiple monitors or a large monitor that can support multiple windows comfortably useful for development, e.g. multi-pane IDE, terminals, documentation all visible simultaneously. The distraction problem is that everything else (slack, email, internet) is just a click away. I wonder if the answer is to treat the computer desktop like a real desktop that only supports having the materials open for one task at a time. So consciously switch tasks by putting the old things away and getting out the new things.

Maybe the fact that slack and outlook take a painful amount of time to open is a feature not a bug

jebarker··on What major works of literature were written after age of 85? 75? 65?
What do you think caused you to stop caring as much? I’ve been becoming more aware of my finitude recently for a variety of reasons relating to middle-age and having kids. A side effect of that is definitely caring less about lots of things in order to focus on others. But I have an internal battle going on with the part of me that says I should still be ambitious and make a dent in the world.
jebarker··on Mathematical methods and human thought in the age of AI
I don’t see why “natural evolution of human tools” implies “such that it can replace and supersede human labor altogether”. Can you clarify?
