lebuffon··on Is the Q source the origin of the Gospels?
John to me as the youngest gospel, is an attempt to solidify what Christianity was becoming as it separated from the remains of Judaism after the destruction of the temple in year 70. It could have been written as late as 200 CE from what I have read. In my opinion that is why it diverges from the synoptic books. It had to address the new religion's theology more overtly as it had developed by then. Christianity was becoming popular quickly, once it became clear that pork chops were on the menu and surgery was no longer needed to join.

lebuffon··on Aboriginal ritual passed down over 12,000 years, cave find shows
I have often wondered if these flood stories document something much larger that might have occurred as the major ice sheets collapsed and raised the sea levels to unseen heights.

But the one that is most intriguing IMHO is the mediterranean sea event that happened but it is 6M years ago. Could ancestors of genus Homo have passed that story long for all that time even across speciation???

lebuffon··on Swiss Broadcasting Corporation to pull plug on FM radio
That "sound" is partially due to the design of the current AM system. It was built to pack more transmitters into the allocated frequency range.

There are no technical impediments to high fidelity audio because of amplitude modulation. In the past the big limitation was the bandwidth of intermediate frequency (IF) amplifiers in the receivers which were typically tuned for maximum gain and not flat audio band response. The transmitters have flat response out to the legal limits. Radio stations have a monitor receiver that has proper IF audio response and the sound of those are very good.

lebuffon··on A Forth Story (1995)
Correction: The CPU was named NOVIX 4016. The next iteration was the Harris RTX2000.

A quick history of this work is contained in this thesis by Charles Eric LaForest.

An interesting test would be to correlate birth date results with people from the southern hemisphere. "Western civilization" is very north biased IMHO.
lebuffon··on A Forth Story (1995)
Ya that chip is really weird. Each core is so minimal that people struggle to understand how to use the chip. I think something less "fanatic minimalism" would be better but hey that's just me.
lebuffon··on A Forth Story (1995)
IMHO the world has missed the real thing Chuck Moore invented, that being an alternative CPU architecture. The use of two stacks, one for data and one for sub-routine linkage had not been seen to my knowledge, before Moore.

Forth is not a language. It's an extensible instruction set. You like RISC. Are 31 instructions "RISCy" enough? :-)

I have wondered what Chuck's CPU designs could have become if they had been given more financial and intellectual support at the level that we see for the dominant machines in the world.

Chuck's first CPU NOVIX 2000, performed multiple instructions per clock without pipelining, Interrupt handling in 2 clocks, sub-routine calls in 1 clock and return was 0 clocks on many instructions. That was done with a ridiculously small number of gates.

In later years Chuck realized that a dogmatic use of only the data stack was not ideal and he added an a address register and a loop counter register to make the machines faster.

It would be cool to see someone carry these concepts forward to see what's possible.

lebuffon··on Are animals conscious? New research
Sorry, no I do not.
lebuffon··on Are animals conscious? New research
Harari gave me some insights when he explained that when humans lived closer to nature, as hunter gatherers, we tended to see the continuum of life on earth. "God" was in everything. After the advent of agriculture and animal husbandry it became necessary to change our views in order to raise animals to slaughter and eat them.

Religions after that time separated humans from the rest of the animal kingdom and provided the justification we needed from a "higher power".

lebuffon··on Viagra improves brain blood flow and could help to prevent dementia
Marketing as I was taught in a fortune 500 is the end to end process of delivering a product/service to the target customer. Good product is the table stakes. (entry requirement) Everything else is in the marketing plan.
lebuffon··on Viagra improves brain blood flow and could help to prevent dementia
I know a former executive of the company that was developing this drug for cardiovascular problems. He told me that they sold it because it had this "side-effect" that they couldn't get rid of. ;-)

Marketing is the key to business success. (Talking to you, tech people)

lebuffon··on Ancient Chesapeake site challenges timeline of humans in the Americas
There is an elephant in the room in my opinion on the matter of a migration to N. America across the atlantic, however I have not read a definitive evaluation of this piece of evidence.

There exists, mostly in the northern tribes (Ojibwa 27%, Sioux 15%) mtDNA of the X type. As I understand it the other highest group in the world is the Druze population in the Levant. (27%) What it all means is above my pay grade.

lebuffon··on A ‘plague’ comes before the fall: lessons from Roman history
It is possible for both dying "from" and dying "with" to be true. (although the medical meaning of each is imprecise IHMO)

I have read that many (most?) of the victims of the 1918 flu pandemic did not die from the virus, rather the virus weakened them to the point where pneumonia bacteria took hold in their lungs. With no recourse to antibiotics many did not survive the bacterial infection.

This sounds like how my great-grandfather died. It was reported that he contracted the flu and was sick for two weeks but began to recover, then relapsed and died. Sounds like a bacterial secondary infection after a viral infection.

lebuffon··on Ask HN: Seeking ideas for preschool/school projects
Not really I cobbled together some notes from Internet content. Of note since it was a church based group, I referenced ancient time to biblical figures and the estimated dates of their time because they new of these characters. (I had to puncture the 6,000 year old earth idea, but I didn't hear complaints from parents so I guess they are not in that camp)
lebuffon··on Ask HN: Seeking ideas for preschool/school projects
The 4 year olds may be too young,but I am a big fan of teaching how we got here.

I gave a 6 session course to a homeschool coop on the History of Technology starting from stones and moving through bronze age, iron age, steam power, electricity, telegraph demo (big hit) radio and TV and early computers.

(I think Engineering schools should have a course on tech history)

lebuffon··on AM radio law opposed by tech and auto industries is close to passing
FM takes whatever bandwidth you allow it. The harder you hit it the wider it goes. The limiting factor is when modulation exceeds the bandwidth of the receiver, it clips very badly.

Narrow band FM is used for aircraft. police, fire, amateur radio communication and since 2021 it's even legal for CB radio in the USA. It's deviation is limited by law to about +/-2.5KHz, from centre frequency.

Setting up the modulation depth on an a broadcast FM exciter, I have used a spectrum analyzer and Bessel function information to make sure it was legal.

lebuffon··on AM radio law opposed by tech and auto industries is close to passing
"AM" is the modulation scheme. A more accurate name for this radio service is used in Europe, "middle-wave".

The modulation scheme is not the reason for propagating around mountains and bouncing off the ionosphere at night. The reason for that behaviour is the low frequency used. 540 Kilo-herz to ~1700 Kilo-herz. (I was told once by a young engineering colleague that 1,000 Khz was not RF. :-))) )

So the question is valid. FM could be used in the "middle-wave" band. It would reduce noise but might suffer more when bouncing off the ionosphere at night. (I have read this but never heard FM bounced)

The reason FM is not used in the middle-wave band is legacy regulation not technology.

lebuffon··on How Matzo Is Made
If you have latin american ancestry there are people known as conversos. There were other places besides Spain, in middle ages Europe where people hid their Jewish backgrounds, attended church and blended in to protect their families but some traditions persist. There may be a family secret in your background. Mazel tov!
lebuffon··on No joke: FTC boss goes on the Daily Show and is told Apple tried to block her
This book has an interesting insight on these matters.

https://www.amazon.ca/Technofeudalism-Killed-Capitalism-Yani...

To me the 20th century leaders completely failed to understand the immensity of the changes brought by information tech and so failed to use the legal tools available. The anti-monopoly laws were only applied to Microsoft, as I recall, around the browser/Operating-System combination. That showed they had little understanding of the big picture IMHO.

So they missed that one, imagine how badly they are going to miss the AI revolution...

We have so many "bandaids" but very few cures these days. Perhaps AI systems will allow us to find root causes of these insidious diseases.
lebuffon··on Younger Generations Have Larger Brains. Is That Healthier?
"It would be cheaper to cure the disease..."

<pessimist> Cheaper would also mean less revenue generated by ongoing symptom control medication. (Asthma inhalers for example: ~$13.4B global 2021, CAGR=20% !!)

There is less business incentive these days to prevent or cure disease from what I can see. We have prevented a lot of the really big diseases that scared the hell out of people in history. (with some notable exceptions)

Today a cured person is a lost consumer to a pharmaceutical company.

The only solution to that issue, that I know of, is some form of government incentive to artificially subvert the natural market pressure but that is distasteful in free-market countries and money "invested" in political campaigns can "motivate" politicians to steer clear of those waters.

lebuffon··on How photos were transmitted by wire in the 1930s
These were called "leased" lines. You ordered them and the Telco set them up for you and billed you like any other service.
lebuffon··on How photos were transmitted by wire in the 1930s
Yes. The audio quality of land line phones was dictated primarily by transducers. This was by design. The TIA published specs for USA, Canada had their own as well as most other countries.

The response of a twisted pair was pretty good over 2 to 4 miles as I recall but for a audio grade (50Hz to 5000Hz) various techniques were used that at the simplest involved coils but there were also active equalizers available for long haul circuits and/or "hi-fi" requirements. Remember DSL lines were/are shipping 1..2Mhz carriers over those same old telco lines. :-)

Of course some old trunk lines used paper insulation. Really. Which meant noise went up ... when it rained.

lebuffon··on How photos were transmitted by wire in the 1930s
Yes, ISDN was the higher priced product offered by the telcos but ISDN was not available until the 1980s. Radio broadcasting started over 60 years earlier and analogue lines were the only option.
