JoeAltmaier··on The Surprising Self-Awareness of Fish Revealed in Mirror Study
Makes sense - surface reflections are a thing they normally have to navigate?
JoeAltmaier··on Growing proof that autonomous cars save lives
Human-readable? Why? Just sprinkle RFID tags in the roadway, and drive it and register the tags and GPS/Inertial frame with a database and now you know where you are with machine-readable 'signs'.
JoeAltmaier··on Growing proof that autonomous cars save lives
And what fraction of the traffic?
JoeAltmaier··on Growing proof that autonomous cars save lives
Pedantically true. By population density, NYC is essentially the whole state, or what matters anyway, to the huge majority of residents.
JoeAltmaier··on Growing proof that autonomous cars save lives
We'll have arrived at the automated transit network when they stop putting up road signs. The cars know where they are, and how to get there. Signs are for fallible ignorant humans.
JoeAltmaier··on Le Creuset x Star Trek: limited-edition pieces bring Star Trek into the kitchen
Grotesqueries that would give me nightmares. With the exception of the communi-grater which is just cool.
JoeAltmaier··on The Growing Proof That Autonomous Cars Save Lives
Just numbers? Was there a link to the sources in there?
JoeAltmaier··on Nobody Is Saying Why OpenAI and Anthropic Had Outages
Not that uncommon. It's so easy to just put up the new thing and make the old thing the failure route. But the old thing nearly never had the bandwidth for today's traffic. A famous EBay outage some years ago was just such a scenario.
JoeAltmaier··on The Computer Museum of America reclamation project
Cool! The pictures remind me of my business partner Tom's basement - full of every computer and device he ever owned since the 1970's. But his are more orderly, sorted and filed and often in the original packaging. It'll be a great contribution to some museum one day.
JoeAltmaier··on Senator calls for criminal investigation of RFK Jr after Guardian report
Really? The man directly responsible for defeating all measures meant to protect the public? Sounds serious to me.
JoeAltmaier··on Coconut oil jet fuel matches kerosene's efficiency in engine tests
Thanks - I was using the wrong table, total coconut or something.
JoeAltmaier··on Coconut oil jet fuel matches kerosene's efficiency in engine tests
All water under the bridge. Ethanol is now a paying proposition. And it uses corn we used to dump.
JoeAltmaier··on Show HN: I wrote a BASIC interpreter that boots on UEFI machines
Very cool! The raw-metal boot part is impressive.

BASIC requires more support than you'd expect. Here's an interpreter, with a similarly long list of features it has to support:

JoeAltmaier··on Z80 – The 1970s Microprocessor Still Alive (2021)
It's still active as a mask for a more complex system on a single die. Even the support chips are available. The Juno project, orbiting Jupiter, had a Z80 compatible core for the radar signal processing.
JoeAltmaier··on Z80 – The 1970s Microprocessor Still Alive (2021)
My first ambitious project was a Z80 assembler. The Z8000 (much later) was distinguished by being the last random-logic (not microcoded) microprocessor of it's day.
JoeAltmaier··on I like 'em thick: an apology to my English teachers
About the benches: seems like an oxymoron. New Yorkers love busy places! Of course; they live in New York. Plenty of people on the benches in my midwest city park. Because we by and large are uncomfortable with crowds and noise. Why we don't live in New York.
JoeAltmaier··on Why the Ocean Cleanup hasn't solved the plastic pollution crisis
Agreed
JoeAltmaier··on Why the Ocean Cleanup hasn't solved the plastic pollution crisis
Read again? Negative is the enemy of good, and this project was a net negative. As PR it went well, if you didn't examine it too closely. It was a misnomer from the start - it was 'harbor cleanup' or 'river cleanup' really. Where the big obvious plastic objects are. I don't believe they proposed any method for actually cleaning up the 'garbage patch' which consists of pepper-sized particles of plastic that requires a sieve to see. And which has been colonized by many marine creatures, so 'cleaning it up' would have the side effect of mass sterilization.

Issues are hard. PR is easy, especially if you hand-wave over the hard stuff.

JoeAltmaier··on How to put 170 atoms in an atom
Wait - if the 170 atoms are a Bose-Einstein Condensate, then they are really just one atom. That's the whole deal with Condensates.
JoeAltmaier··on RISC-V: They Should Have Known Better
Oh I remember SYSENTER/SYSEXIT, I think. I worked on CTOS, widely released by Burroughs/Unisys back then. CTOS used all the clever instructions. They performed badly. Later I learned from an Intel customer consultant on porting code, that we were the only ones who ever embraced fancy things like task gates etc. Everybody else just continued using regular push/pop and simple traps. Because they ran faster.
JoeAltmaier··on Shattered skeleton is first confirmed death from trebuchet
Interesting find! I wonder if the massive damage could also be explained by the falling wall (documented in the article).
JoeAltmaier··on We're entering the human era
SOrry, I meant 'from the consumer point of view'. Once the billions are spent, I just update my version.

Yes so far the AI takeover is overblown. I see that changing - at some point, the AI functionality will improve to the point it CAN replace people for many things. Every year it is leaps and bounds beyond what came before.

JoeAltmaier··on U.S. and Ukrainian Forces Went Head-to-Head in an Exercise. Ukraine's Drones Won
Hell, let some inventive sergeant command the exercise 'insurgents' and they win every time. Such examples are remarked upon in nearly every branch of the US services.
JoeAltmaier··on Could distributed systems be taught from first principles?
Like this? https://dthain.github.io/distsys-fa24/syllabus.html
JoeAltmaier··on We're entering the human era
The argument balances on, AI Doesn't Care. Well, put that module in, then it does care.

The advantage to AI (why it will never go away) is that it can be updated, universally, on a dime. With new techniques, skills, logic and ultimately even 'caring' whatever that means to us.

We're entering the AI era. Don't be fooled.

JoeAltmaier··on "Revolution by robot – The Brain that talks to Tools"(Popular Mechanics 1959)
Science fiction investigated so much. Like, if AI can control our technology directly, why do we need to be in the equation? We've invented a superior intellect. In every way it exceeds our own.
JoeAltmaier··on The Day We Almost Let a Bot Lose Us a Loyal Customer
My bank AI support says it solved my problem, fixed my account and so on. And then precisely nothing happens. It's maddening. I just go into the bank now, and talk to a VP. How does that improve the situation?
JoeAltmaier··on AI Fortunes Are Reviving an Old Debate About Private Power
Non-voting shares? That you can't sell? How is that ownership? The rules for these shares seem to strip all ownership rights from them.
JoeAltmaier··on AI Fortunes Are Reviving an Old Debate About Private Power
A nice thought. But the early options/shares issued at a startup have been gamed to the point that only the principals can ever get a significant cash payout. THe rest of the employee shares are of a special class that may as well be called 'worthless paper'.
JoeAltmaier··on Matt Mullenweg's Messages Went Missing Amid a Failed Backup and Two Lost Devices
In my personal history, no self-made backup tool has ever produced any good result in a failure.

It's a case of, if you haven't tried it, it doesn't work. And who tests their backup?
