So does this mean that whenever one is working in 8 bits that it’s taken for granted that the upper bounds represent negative integers? Or does it rather depend on the context?

Very well explained.

Amazing! Thank you for sharing.

My wife and I are moving from a Bortle 9 (NYC) to a Bortle 3-4 (Upstate) soon and I'm excited to start attempting more DSO imaging. Up to now I've been mostly focused on capturing Jupiter and Saturn which are, honestly, challenging as it is.

After trying to perfect my ramen broth recipe I’ve incorporated seaweed into all kinds of other foods. I made an outstanding (if I may say so) ragu the other day that I began by including dried seaweed (and bonito flakes) in the soffritto.

This reminds me of an investigation by the Times from September 2022 into Providence health system’s training of employees, with the aid of McKinsey, to “[wring] money out of patients — even those who were supposed to receive free care because of their low income.” https://www.nytimes.com/2022/09/24/business/nonprofit-hospit...

A project I worked on a while back highlighted the problem of speculation in Detroit’s land market.

No comment other than I’m very happy to see this from my alma mater on the front page of HN. I hesitate to say it’s a woefully underrated school, but I’m nevertheless proud of it.

I love my hometown.

Mid-19th century?

Apropos of nothing about the house, I’m confused why someone would use the “Antebellum era” to periodize something in New York?

It's unclear to me how social democracy could be achieved without a labor movement.

Perhaps, but favorable labor legislation often depends on a robust organized labor movement, especially in the United States (where no labor party is present).

My friends and I had only a few LAN parties that I can recall, at least ones that took place at any of our homes. There was, however, a PC repair shop in town that had a (pretty high-end for the time) LAN gaming room. I wanted to learn about computer repair, and so offered to work for them once a weekend or so, for a few hours, in exchange for learning about computer repair and free gaming for my friends and I. After raising an eyebrow, they agreed.

In the end, I don’t think I really learned all that much. (The solution was often to just backup what we could of a person’s storage and reformat.) But my friends and I had a good time at this shop, run by two computer geeks of an older generation, that was probably just a few years shy of being wiped out by the Geek Squad and Genius Bar.

Apart from that, my school district had a kind of magnet career skills center that offered a network administration course. On Fridays the instructor would let all of us in class play Counterstrike on the classroom’s LAN. I think that was put a stop to, however, after a district supervisor came into the room just as a student gleefully yelled, “Headshot!”

You mean like swapping caps lock for control?

The Schooner Trinidad just doesn’t have the same ring as The Edmund Fitzgerald.

The first couple of episodes of the podcast “The History of English” about PIE are fascinating. I’d highly recommend it for anyone interested in a quick intro to PIE (or the rest of the podcast in general, if you’re interested in the history of the English language).

Speaking personally, I feel like any time I save by reducing keystrokes would be lost by having to think about shortcuts (or making corrections). However, I Once believed the same thing about vim-mode (which I believe saves me time though I couldn’t prove it).

I read “On Writing Well” recently and really enjoyed it. The author cites “Elements” frequently.

The fact of un-readability isn’t necessarily implied by the statement being replied to. `map` and `filter` are names for common operations on lists, not less performant alternatives other things. If there’s a more performant alternative to either operation, give it a name and express it in a function. That’s what functions are for, no?

In the early-mid aughts I volunteered at an anarchist bookstore in Detroit. One day, this guy comes in to tell us about a show he’s playing. He’s holding a promotional poster for it.

“So you want to put the poster up? No problem!”

“No, man. This is the only poster I have. I’m just going around to show it to people and let them know.”

Later, someone told me his name was Rodriguez. I thought that was so funny at the time, but even more so after the success of “Searching for Sugarman.”

Rest in peace.

Don't get me wrong, I really believe there are helpful tools out there. For instance, Notion has been one of the most genuinely useful applications I've ever used (like, it has genuinely improved my quality of life by helping me organize things for work, my personal life, household chores, side projects, etc). On the other hand, I also see how for others like me with ADHD, something like Notion could be overwhelming and therefore totally useless.

I suppose that's my point. ADHD has such a diverse battery of symptoms (many of which are also expressed in other pathologies) that targeting just one of them with an app and then pitching it as "an app to help with ADHD" is very unconvincing (if not downright lazy, if not cynical). An app made to do a generally useful thing pitched to anyone who has the need for that thing, however…

> it solves problems that I don't have, and ignores the ones I do have

This is exactly what I suspect of virtually any kind of app, software, platform, etc. I’m advertised as intended to help me with ADHD. ADHD is expresses itself in such a broad variety of ways. I just don’t trust that any kind of app is actually so tuned into my experience of ADHD that it could actually be helpful.

I hesitate to say this: but, it’s hard hard not to feel offended at times by the ways in which ADHD appears to be radically oversimplified to fit into a narrow product specification and pitched to people who might really need help.

+1 to “The People’s Tycoon”

“America By Design” and “Forces of Production” by the historian David Noble[1] discuss the relationship between capitalism, management, and the development of technology.

From Wikipedia,

> “America by Design”…was published to unusually prominent reviews. Robert Heilbroner hailed it as a work that "makes us see technology as a force that shapes management in an industrial capitalist society.”

> “Forces of Production”…recounts the history of machine tool automation in the United States. [Noble] argues that CNC (computerized numerical control) machines were introduced both to increase efficiency and to discipline unions…[and] argues that management wanted to take the programming of machine tools…out of the hands of union members and transfer their control, by means of primitive programming, to non-union, college-educated white-collar employees working physically separate from the shop floor.

Sorry, but could anyone share some background (reading, links, etc.) on set vs. category theory as applied type systems?

Good time to grab a beer!

I had no idea about these elements or their APIs. Maybe one downside to living in JSX all the time is that it can encourage ignorance of the foundation it’s built on.

For me, not taking my hands off the keyboard (or more specifically, not touching the mouse) is less about speed, and more that it helps me remain focused on what I’m doing.

I was coming here thinking the same thing. The important thing isn’t abstractions in general, it’s whether those abstractions are useful (defined here as reducing the cognitive load of a reader, but there’s probably dozens of other meaningful definitions of a “useful” abstraction). That can depend on a number of factors, e.g. the particular programming idioms, flavor, style, etc. of a team; the quality of documentation and onboarding of new engineers to a team; the specific task at hand, etc.
