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?

JoeAltmaier··on Assembly Hall of Shame
Was I thinking of 0x86?
JoeAltmaier··on 2027 memory capacity is reportedly sold out
It takes a billion dollars and years to produce a new chip fab line. So no, it cannot just be produced for you on a dime.
JoeAltmaier··on Assembly Hall of Shame
There were several NOPs - XCHG BX,BX and so on. Those were taken later to be prefixes for new classes of opcodes.
JoeAltmaier··on Owner of bike maker Raleigh files for insolvency
In the US, it's estimated the average kid's bike goes less than 10 miles in it's lifetime.

JoeAltmaier··on What if I can just do it faster than talking to you?
What if you end up with unmaintainable junk? What if it almost works, and you have to fix it, and you have no idea how?

None of this is new ground.

I admit at first, I thought the title meant, what if I can fix the issue faster than you can explain it to me? Because I wrote the code, and know where the demons hide.

JoeAltmaier··on Karpathy’s Pelican
I ride a recumbent trike, and the chain path is even more grotesque. I think I could draw it.
JoeAltmaier··on The Quest to Track Down Every Official Liberty Bell Replica Created by Congress
Reminds me of the copper statue-of-liberty program at a similar time. Local youth groups (largely the Scouts) would do a fundraiser for the pedestal, then a foundry in Kansas City would ship you a six-foot (or so) replica in metal. Still can be found throughout the midwest - Iowa has some 200 in parks and public places.

JoeAltmaier··on Zitron: "Everyone Has Been Sold a Lie" on AI
Another view of that is, hedging their bets. Which businesses do all the time.
JoeAltmaier··on The tiny holdout building in the middle of Macy’s is back in view
"The Bronx" was "The Bronks", a farm owned by a Dutch family and a popular picnic destination before it was subdivided and built over.
JoeAltmaier··on So you want to use plants to reduce CO₂
Of course, do it with vats of plant cells in floating oceanic CO2 factories. Not in your living room.

Or, just let the oceans recover, let the mollusks return to the bays and shores, let them do their efficient thing.

JoeAltmaier··on Why DNA damage from smoking and UV rays cause cancer in some but not others
In mice
JoeAltmaier··on After laying off Battlefield 6 developers, EA pays its CEO $38M
Contractors same deal. Work on some big company moonshot style thing and just as it's all in the can, you're let go.
JoeAltmaier··on Finland to Cut Cable Lines Carrying Up to 70% of Russia's Foreign Web Traffic
Ballsy
JoeAltmaier··on Headteacher had the most guessable username-password combo you could imagine
All of us prioritize our lives over cybersecurity. This whole security theatre game was thrust upon us. It has no bearing on our real lives; it's just a task we've been given with a dozen different rules and dire consequences.
JoeAltmaier··on The First Thing That Ever Sold Online Was Pizza (2018)
Swiftly followed by an Orange County Harley-Davidson shop that sold parts and shipped around the world. Was much talked about at the time.
JoeAltmaier··on The state of open source AI
capability has been advancing faster than raw FLOPS
JoeAltmaier··on The state of open source AI
A bold prediction. Phones have gigabytes today. There are famous laws of growth that put terabytes at just a few years away - perhaps 10 isn't too bad an estimate?
JoeAltmaier··on The US grocery slowdown is real
Shelves are fairly spotty in my town. Never saw that before, not in 50 years.
JoeAltmaier··on The Zilog Z80 has turned 50
My son programmed a Z80-based instruction set into a Juno probe sensor. Still kicking.
JoeAltmaier··on Was ¥4.3T Wiped Out from China's Stock Market Today?
Contrary to that old headline about questions always answerable by no, curiously this one is Yes. Despite 'explanations' that reframe the loss and temporizing that maybe it will probably come back, without evidence.
JoeAltmaier··on Guide to help people Transplant to the Bay from the Midwest
We didn't need a guide in the 1980's. My first job out of Stanford was a startup called Convergent. Somebody put a wall map of the US up, with pins, Where are you from? Two from LA, one actually from San Jose and so on. And six from Iowa. One of them was my classmate and one a TA from one of my classes at UofI.

None of us knew the others would be there.

Turns out the issue was more, locals getting used to Midwesterners I guess?

JoeAltmaier··on Solving Santa Claus Puzzle
Confused: they are 'waiting' if they are in the queue when the queue is polled. What else could 'waiting' mean? How is time involved at all?
JoeAltmaier··on India reached Mars on its first try with a mission that cost less than a film
I wonder if a microsat could do the elliptical orbit and small nudge technique to leave Earth and enter Mars orbit too? A microsat has very little reaction mass. But it has very little mass altogether - under 100 kilo by definition.

It might be a way to deploy GPS satellites to Mars without a major mission effort?

JoeAltmaier··on Washington Law Says to Alert the Public When Doctors Are Accused of Misconduct
Who do we alert when Washington is accused of misconduct?
JoeAltmaier··on Ask HN: Are we there yet? Can I create a human analogue using AI?
I'd guess the training data would be a combination of baseline personality behaviors (turn-taking conversation, basic social skills, education level) with data specific to an individual. Recordings, letters, perhaps online posts but that's potentially not representative of the person since online is typically 'impersonal' by design.

Some of us may have too little to 'go on' to make a convincing avatar. Others may have biased samples, perhaps from lectures or recordings of performances.

Probably it may require an interview with those than knew them well. There would be memory bias, and the natural tendency to speak kindly of the dead. That might even serve the purpose better - it's a memorial after all, meant to be presentable and maybe not reflect the worst aspects of a personality.

JoeAltmaier··on World-War-Ⅱ-era telephone line still in use in Upper Tanana Valley Alaska (2021)
Pockets of frozen technology persist from time to time. As a kid (60 years ago) we had a wooden telephone with a cone on a hook and a speaking horn out the front. A large D battery inside the wooden box. You took down the cone and rattled the switchhook it hung from to get the operator's attention - your light would flash on her switch board. She'd ask, and plug your line into whoever you wanted to talk to.

In the 1960's long past the time that party lines and manual operators were supposed to be extinct. But, rural Iowa.

JoeAltmaier··on Can humans hibernate their way to Mars?
Curious idea. How about, use an atomic rocket engine and get there in a couple of weeks? Binge on Netflix the whole way.
JoeAltmaier··on Fundamentals of Wireless Communication (2005)
Lots of innovation in 802.11 and it's ilk.

Early versions had a fairly fatal flaw. They responded to bad reception (reception but failure of checksum etc due to interference) by 'downshifting' e.g. reducing their transmission rate from 10Mbit to lower rates.

This seems rational, but in practice it usually shifted all the way to the minimum (1Mbps!) and got no relief. In fact, packets were 10 to 100 times 'longer' in airtime, congesting the channel so nobody got anything through.

Why did they get no relief? Because frequently the noise was bursty e.g. microwave oven pulse or auto spark plug noise. Going slower meant larger (longer to transmit) packets, which provided a 'bigger target' for the noise to poke a hole in.

A more useful response was to try the fastest rate, a smaller packet which got hit with fewer 'darts' impacting any particular packet.
