ggm-at-algebras··on Honda is killing its EVs
In Shenzhen for a tech meeting. The streetscape is quieter, despite high traffic levels and I hear not only MORE birdsong, but the birds do more complex songlines.

The air is clean. For sure some of this is because it's a coastal city and has fresh sea breezes, but I've been in other Chinese coastal cities in times past and the air was significantly less clean.

There are social upsides for an almost-all-EV city.

This is an 18m person city. It's not exclusively wealthy people, its just a city with a very high local EV population and it shows.

ggm-at-algebras··on Paying without Google: New consortium wants to remove custom ROM hurdles
I really want Europe to succeed but I keep thinking the tpm/trust zone keys are going to be a killer here. We need something akin to DNSSEC key ceremonies, combined with the CAB forum to police who gets admission.
ggm-at-algebras··on Rendezvous with Rama
It would seem passing strange that Gentry Lee came up with all the awful bits and the consulting oversight didn't.

Nothing in this thread makes me feel I should change my mind but de gustibus and all that.

If he'd stopped after one, it would have been fine. He decided to do a series. It got weird. I still read them but the original is a decent standalone and you won't die unhappy if you never read the following.

The same could be said of 2001.

ggm-at-algebras··on Notes by djb on using Fil-C
Mate, we're not talking about the future, but about 3 letter guys now. I'm one, I've carried it with me for 40+ years as have the ten or twenty peers of mine I know by their tla. I got it at pobox.com when the door opened, the guy at the desk next door got a one letter name. I set up campus email for the entire uni in 1989 and gave myself the tla with my superuser rights before that. I'd done the same at ucl-cs in 85, and before that in Leeds and York.

My point here is we're not famous we're just old enough to have a tla from the time before HR demanded everyone get given.surname.

Every Unix system used to ship with a dmr account. It doesn't mean we all knew Dennis Ritchie, it means the account was in the release tape.

There are 17,000 odd of us. Ekr, Kre and Djb are famous but the other 17,573 of us exist.

Not to trivialise but being a 3 letter guy means being old. So, it's at best a celebration of achieving longevity and at worst a celebration of creaky joints and a short temper.

ggm-at-algebras··on Humans have an internal lunar clock – but light pollution is disrupting it
> Before around 2010 – when LED lighting and smartphone use became widespread – many women’s menstrual cycles tended to begin around the full Moon or new Moon phases. Afterwards, that synchrony largely vanished, persisting only in January, when the Moon-Sun-Earth gravitational effects are strongest.[0]

Usually I just pass by the refs but this time I felt moved to read.

ggm-at-algebras··on AI models may be developing their own 'survival drive', researchers say
Strong agree. The misuse of analogies to state what these systems are doing is part and parcel of the problem.

Plug an OTG cable in and connect to that, so you don't repeat plug-unplug?
ggm-at-algebras··on Unlocking free WiFi on British Airways
At some point the cost of the meter exceeds the value of the product being metered. This happened very soon after hotels really jacked up telephone bills. Somehow they decided not to stop being silly, simply to bill the ignorant or lazy and airlines look to be cut from the same DNA: we're maybe going to wind up with viable cellular comms inside aircraft that bypasses the airline.

"Stealing" ip flows over Port 53 isn't the way out, the path out is having RF which doesn't flow through the airline's base station.

ggm-at-algebras··on Cardioprotective effect of semaglutide are independent of adiposity and weight
Paper title: Semaglutide and cardiovascular outcomes by baseline and changes in adiposity measurements: a prespecified analysis of the SELECT trial

Interpretation The cardioprotective effects of semaglutide were independent of baseline adiposity and weight loss and had only a small association with waist circumference, suggesting some mechanisms for benefit beyond adiposity reduction.

ggm-at-algebras··on Optical diffraction patterns made with a MOPA laser engraving machine [video]
You need a mechanism which forms interference fringes. Chocolate blooms, so you might be able to etch the bloom.

Otherwise, it's skim an edible oxide layer over the chocolate to etch.

ggm-at-algebras··on EQ: A video about all forms of equalizers
The history behind vU meters is also fascinating. People used to calibrate off the BBC techs, or off American techs.

No BIPM, no SI units: what the BBC say.

ggm-at-algebras··on If It's Worth Your Time to Lie, It's Worth My Time to Correct It
"Lie" is a word I dislike in much discourse. Being wrong, fine. Misunderstanding, fine. The implied intentionality in "lie" demands evidence.

Not always wrong, but overused. My own personal nitpick hot buttons:

* "learnings" should be lessons

* "jealous" should be envious.

ggm-at-algebras··on California Democrats Agree to Roll Back Landmark Environmental Law
The proof of the pudding will be affordable housing, which demands both a fall in property values and acceptance of a lower return on investment for property.

I wish I believed there won't be social engineering and lobbying to counter this.

ggm-at-algebras··on Ask HN: What features would make a Hacker News Chrome extension indispensable?
As few variances from the unadorned ui as possible.
ggm-at-algebras··on Ask HN: What's the 2025 stack for a self-hosted photo library with local AI?
Dedupe over edited photos, and handling highly approximate date information are my "nobody has this right yet" criteria.
ggm-at-algebras··on The Unsustainability of Moore's Law
There has been a relationship between die area and speed for much of time. That stopped being true. Perhaps it was only a side effect of shorter paths on chip.
ggm-at-algebras··on The $25k car is going extinct?
Confirmation bias but a very good friend did this: bought back the hail damaged car from the insurer in preference to keeping the undamaged VW Beetle, sold the beetle, has been driving the hail damaged car with the minimum legal insurance to third parties for 15 years since. She's streets ahead in costs of car ownership and drives long and short distance, urban and country.
ggm-at-algebras··on The $25k car is going extinct?
if you don't believe in market regulations, this is confirming evidence of the distortions of trying to regulate an open market.

If you believe in climate change, this is evidence of how the vested interest behind profit in cars manipulates the intent of the regulations, to continue to get what they want.

It's a bit fish/bicycle, but the point is, we wanted more people to drive smaller, cheaper, less polluting cars. We didn't want the car manufacturers to find ways of maximising sell, including boosting F150 and F250 class truck sales to mummies on the kindy run.

ggm-at-algebras··on The Unsustainability of Moore's Law
I think its possible. When 128 bits came along, I wondered if the very long instruction word people were going to come back into the room. If we imagine mapping addressing into the world, how about making some rules about top bits addressing other nodes in the DC and see how "shared memory" works between distinct racks?
ggm-at-algebras··on The Unsustainability of Moore's Law
What does economics in die area say about using die for highly repeatable simple memory forms, vs complex instruction/ALU? I would think there is a balance point between more cores, and faster cores with more cache and more lanes between them.

We're on 8 as a mixture of fast and slow, hot and cool, on almost all personal devices now. I routinely buy Intel instruction racks with 16 per CPU construct, and a TB of memory. At one remove, chips seem to be fulfilling my mission but I am not in GPU/TPU land. Although I note, FPGA/GPU/TPU seems like where a lot of the mental energy goes these days.

VLSI is a black art. Quantum effects are close enough to magic I feel confident saying few people today understand VLSI. I know I don't, I barely understand virtual memory. I ache for the days when a zero pointer was a valid address on a pdp11

ggm-at-algebras··on The Death of the Middle-Class Musician
Surgeons also police membership, it's an old school guild. We could have many more sugeons, if the restrictive practices were changed. I don't think this answers your fundamental point btw, I think musician==surgeon is only analogous in the time to achieve mastery, the application of the skill diverges.

We did in some ways (cosmetic procedures) go to low cost rental models. They're terrible.

ggm-at-algebras··on The Unsustainability of Moore's Law
More parallelism. Less clock. More l1 cache per CPU and less disk stalls. Are there plenty of tricks in the sea, when clockspeed goes flat?

Dual ported TCAM memory isn't getting faster and we've got to 1,000,000 prefixes in the internet and ipv6 are 4 times bigger. Memory speed is a real issue.

ggm-at-algebras··on The Death of the Middle-Class Musician
Surely for most time, musicians have been working class. And precarious?

I'm not arguing in favour, I'm noting the deep historical social worth of a musician. It's classic veblen goods for a few, and serfdom for the rest.

Composers had ambiguous social standing. Virtuosi were superstars, but you didn't want your daughter to marry one.

What if the underlying relative value of music was returning to its organic roots? Maybe this is a version of the burger index and their labour value has been overweight for 50 or more years?

The cost in time and effort to become a musician is comparable to an apprenticeship or a surgeon. That cost isn't reflected in their value in the market.

Mrs Norris is also superbly well personified. She knows the worth of a roll of green baize. Her life and livelihood depends on it.
