How about this claim: pieces of string when stressed emit sounds that are picked up by nearby strings. Should be investigate this claim? What does it mean that the world of string acts this way. For those that haven't witnessed it, I w

My first hand accounts mostly come from my Father. He was a young Marine Corp officer on Okinawa during World War II. What a sad and terrifying time. He was stationed next to an air base on Okinawa and was issued a gas mask after the bombin

I think you are right, at least from what I've read; I have to admit to no actual experience with actual, modern hardware construction. Maybe some day I'll try tinkering with a hardware project again. I was in college when 555 tim

My digital design class in the mid 1970s used the older RTL (resistor-transistor logic) gates. They had only 2 NOR gates per (TO-5) package; you can still buy these on Ebay for around $6. At the time I wished that I could be using the much

The Pentax 645 was one of my favorite cameras, but years ago I saw that the future was digital. My second consulting contract was for Kodak in late 1990. They were developing a software/hardware platform to support digital media. A few

Algol 60, Algol W, and Algol 68 were influential in the historical development of subsequent programming languages. C gets its type on the left order from the Algol family. Pascal, Modula, and Ada are all type on the right languages and wer

I was in elementary school in Detroit (a city in the US) during the 1950's and the only name I ever heard used for that ubiquitous playground device was "monkey bars". I really enjoyed them as a kid.

I am not the poster you are replying to but calling that post “bad faith participation” surprised me. Stopping ethanol production will lower demand for corn so it is conceivable that this would reduce the marginal value in producing corn an

Macros provide abstractions that often make programs easier to understand. I myself have dozens of the usepackage macro in my Emacs configuration, they hide and standardize the boilerplate that I could use instead. Nevertheless, I have se

I find the big advantage of rolling to be easier access to the rolled items at my destination. I can pick a rolled shirt or pants to wear without rooting through a stack of folded clothes, which usually results in some of the stacked items

According to Wikipedia, Polonium is 5000 times more radioactive than Radium (just 0.001g of Po emits the same number of particles as 5g of Ra). It has a half life of just 138 days so in only 4.6 years the missing Polonium will be equivalent

I agree that it is unlikely to be increasing precisely linearly, but do you have a more specific claim? It is my understanding that the GCMs in use have many “tunable” parameters some of which are strongly stochastic, the component of the m

There is a lot of discussion here about renewables. I recommend a recent paper published in Nature Communications titled "Geophysical constraints on the reliability of solar and wind power worldwide"[1]. It considers mixes of So

The first laser device was demonstrated in 1960. By 1961, patents on lasers already indicated applications in communication and meteorology[1]. Subsequent patents included uses for range finding, chemical analysis of gases, drilling, and ot

The article gets some dates wrong: > The age of the amber monitor lasted from about 1987 until 1990, a mere moment in the history of computers. I remember the first time I used an amber monitor. It was in a dimly lit lab at MIT in my las

Barbra Liskov’s CLU language had multiple returns in 1973, ten years before Common Lisp. I was a student of hers back then. I’m pretty sure I saw multiple returns used in pseudo-code on a class handout the semester before I started working

Naturally, the “curse of Turing” means that virtually any programming language can, with enough effort, do anything. I wouldn’t classify Prolog as appropriate language for general purpose vs say Python. In theory, I could write a replacemen

This isn’t an option for US citizens. Income made anywhere in the world is taxable and requires reporting and payments to the US. Furthermore, giving up one’s US citizenship requires an exit tax that taxes all unrealized gains as if you s

I found Jack London's story so compelling as a kid when I read it. Perhaps it was because I grew up in snowy, cold winter part of the country. Maybe that's why I have around a dozen books on survival, living off the land, tracking

This is an interesting list. I'd add hashing and hash tables to the list. There are lots of interesting variations of these as well. I would put hash tables ahead of piece tables because of their generality. For text editors I've

This is so terrible. It makes me think about comments I heard from John Gretton "Jocko" Willink, an ex-Navy Seal podcaster on YouTube. During the height of the defund the police movement he suggested that doing so would make thing
