mFixman··on Silicon Valley is pricing academics out of AI research
My crazy and political idea what will fix all problems is to give proxy votes to parents for each of their children.

A lot of teacher salary problems come from idle retirees outvoting children on personalised social care vs mass school funding. There is no reason for children to have absolutely no representation in government.

mFixman··on Linux TTY font for Chinese, but treat it as a syllabic writing
Can coda 'r' be combined with any initial, medial, or rhyme other than 'er'?

I thought er-hua was only used for 儿 and homonyms.

mFixman··on Simpson's paradox
It would be Simpsons' Paradox if Google services in Indonesia were initially slow because Indonesians tend to use YouTube more often than lighter services.

There wasn't an error in the conclusions of the initial measuremen. It was the solution that had problems.

mFixman··on Open-source project ZLUDA lets CUDA apps run on AMD GPUs
Neat, that makes sense.

Still, giant missed opportunity for AMD not to focus on this when NVIDIA has an almost monopoly on massive GPGPUs.

mFixman··on Open-source project ZLUDA lets CUDA apps run on AMD GPUs
Why is it so hard to develop a CUDA-like to AMD-opcode compiler?

If it wasn't taking the tech community so long I would imagine it would not be harder than porting GCC to a new architecture.

mFixman··on Dune: Part Two Is the Best Sci-Fi Film of the Decade
I read the Dune books after seeing Part 1, and I was slightly disappointed at how _little_ characterisation most characters have. Most of them have no history or relationships outside of the ones present in the book and very broad "Paul's doctor came from the secret society of very good doctors".

IMO Dune a good piece of literature, but the lackluster worldbuilding makes the Universe feel small and empty. Nothing interesting happened in the prior 10k years to anybody who's not a protagonist.

mFixman··on Ask HN: What are some actual use cases of AI Agents right now?
> You can do handwritten digit recognition with 90% accuracy? Sounds pretty good, but if you need to turn that into recognizing a 12 digit account number you now have a 70% chance of getting at least one digit incorrect.

You are assuming that the probability of failure is independent, which couldn't be further from the truth. If a digit recogniser can recognise one of your "hard" handwritten digits, such as a 4 or a 9, it will likely be able to recognise all of them.

The same happens with AI agents. They are not good at some tasks, but really really food at others.

mFixman··on PEP 701 – Syntactic formalization of f-strings
Be sude that would make it hell to write strings with literal {}.

I like having different types of strings with different sets of magic characters. Even having identical `'` and `"` strings just to avoid backslashes in a few cases is great.

mFixman··on I applied for a software role at FedEx and was asked to take a personality test
Don't all of these have obvious right answers? What's the point of these if 99% of the people would choose the same?
mFixman··on A new way to discover places with generative AI in Maps
I expect SEO to break Google's AI soon, like they broke PageRank.

Imagine finding guides on HN about how to make your shop appear first when searching for any of the top 500 words.

mFixman··on Android now lets you transfer eSIMs between your phones
I use https://esimdb.com/uk instead of a single app.

It lists the cheapest e-SIMs for travelling to each country.

mFixman··on Noisy brain may underlie some of autism's sensory features
I found that podcasts help a lot with noisy brain at night, particularly long-form multi-episode podcasts that force you to pay attention.

Podcasts flood my brain with non-anxious information and, unlike books, you don't stop "reading" them when you are dozing off and in the early phases of sleep.

mFixman··on Americans are spending billions on stuff they forget to cancel
I just cancel most monthly subscriptions as soon as I get them so I have to consciously re-subscribe every month if I want to use them.
mFixman··on "Paste this post into ChatGPT 4"
Also under that thread, a seemingly white background image that produces an ad when lasted on ChatGPT: https://x.com/goodside/status/1713000581587976372

This is a fantastic attack vector. It sounds like something from an Asimov novel.

mFixman··on Spot Bitcoin ETF receives official approval from the SEC
What's the difference between those 11 tickers? Shouldn't all of them go up or down the price of bitcoin plus/minus a very small error rate?
mFixman··on ChatGPT for Teams
Like a big chunk of the language, English capitalisation is nonsensical and descriptivist. Different organisations have different rules just like different audiences have different expectations, and there is no single way to capitalise words in titles.

I'm with the parent comment on this one: for this particular headline it makes sense to lowercase "teams", since the HN audience will tend to correlate the uppercase version with the incorrect meaning of the headline.

mFixman··on Disney's earliest Mickey Mouse enters public domain as US copyright expires
Does that mean that I can publish a Mickey video in New York that's illegal to watch in California for the next couple of hours?

Neat.

mFixman··on DeskHop – Fast Desktop Switching
Can't you double click the left or right edges of the video to scroll 5 seconds to the past or future?

This works in my modded old version of the YouTube app; Alphabet might have removed it in newer versions.

mFixman··on Uniqlo's Automated Self-Checkout
The evolution of this is fully automated checkout like in Amazon Fresh stores.

It's fantastic: I can go to the store, shove some groceries in my pockets or backpack, and walk out in 45 seconds. Amazon pings you a notification telling you how long you were there after you leave, and I'm convinced they do it to have people try to improve their shortest times.

mFixman··on My failed attempt at using a closet as an office
Back during the pandemic I made a couple of bicycle laps in my local park as a commute between my bedroom and my study before I started working, and a couple of bicycle laps the other way around when I finished working.

It was fantastic to have a mental break between work and not-work, and I didn't fall into the trap of working an extra hour because I have an hour fewer of commuting.

mFixman··on Location history data in Google Maps will soon be stored on user devices
Many countries don't stamp your passport anymore, many that do don't put a date, and even if I relied on that information stamps are messy, out of order, and fading.

The government probably has a list of international flights I've taken somewhere. I honestly don't think they will use it they probably don't deny citizenships because I missed a couple of trips (unlike, say, not reporting frequent trips to North Korea).

It's still nice to do the right thing and fill up that data to the best of my knowledge.

mFixman··on Location history data in Google Maps will soon be stored on user devices
It was priceless when filling my naturalisation application, which required me to write the exact dates of every international trip I did in the past 5 years.

Also, it's great for trying to fit loose memories in dates and locations.

mFixman··on Ubuntu 24.04 LTS will enable frame pointers by default
Ohh, I misunderstood what Ubuntu was doing.

So the only change is that GCC and its toolkit will compile programs using a register as frame pointer by default? That seems like a very reasonable change. If having an extra general purpose register is critical for performance of then this can be disabled in that program's the makefile.

mFixman··on Ubuntu 24.04 LTS will enable frame pointers by default
Could programs compiled in architectures with 16 general purpose registers fail in one with 15?
mFixman··on Ask HN: Is ChatGPT making tech publishing obsolete?
Agreed completely.

LLMs are making the quick jot to Stack Overflow obsolete, which solves your immediate problems using the least amount of brainpower.

They are also making reference-style documentation and long-form books more important than ever, since you still need to learn things and correct your own knowledge biases.

mFixman··on According to Plutarch, Julius Caesar was once captured by pirates
The introduction of the potato and the invention of the steam engine changed Europe several orders of magnitude more than Napoleon or any other great man.
mFixman··on Brain waves usually found in sleep can protect against epileptic activity
I'm lucky to never have had seizures but I had a constant muscular ticks when I was a teenager that mostly went away as I became an adult.

My experience is consistent with your theory of neural pathways getting set, with the exception that I still have get repetitive head ticks on multi-day periods of high anxiety. I completely believe that better and more consistent sleep as an adult (outside high-anxiety periods) also has a lot to do with it.

mFixman··on New York will plant trees using new tech to maximize foliage impact
If migration is the only reason rents increase, why have they been increasing everywhere?
mFixman··on Python Is Easy. Go Is Simple. Simple != Easy
To be honest, I used to use Go before generics became a thing.

I'm glad that they implemented some basic library functions 10 years down the line.

mFixman··on Python Is Easy. Go Is Simple. Simple != Easy
I used Go for many years. My issue is that it's _almost_ a great language, but in its current version it's just a collection of foot guns that makes it difficult to get shit done.

Go doesn't have some of the most library functions, so large codebases shared between teams end up with a dozen different implementations of functions like "minimum" or "filter". Good luck debugging a bug in one of the implementations.

The exception-less error handling would be great if they used sum types instead of (val, error) tuples. Return types are required to have a "default" value if you want to return an error, and good luck finding bugs where you use that value and forget the "if err != nil"`.

Worst of all, they removed most "fun" C things about pointers (like subtracting pointers in the same array) but kept the null pointers themselves. There's no way to ask for a not-null pointer at the type level, so you have to check for nullity everywhere and good luck debugging those runtime panics.
