It's people over 65. Cell phone ownership is pretty much universal, but only 78% of people 65+ own a smartphone. I don't think that's really surprising at all. I wouldn't expect an 80 year old to adopt a smartphone when their cognition, fine motor control, and/or vision is going. And who needs one in a nursing home? I bet if they broke it down further you'd find that the non-ownership skews towards people who were already elderly ~15 years ago.

Tragic. Most of the crew onboard were almost certainly aerospace engineers tasked with collecting sensor data.

Perhaps unsurprisingly, in New England jam seems more popular than jelly. The FDA regulates the labels...jelly is made from fruit juice, while jam is made from fruit chunks. The only jelly I routinely see is concord grape jelly. Jams are usually apricot, raspberry, or strawberry.

Given the number of small batch jams available at various farmers markets, my guess would be that for smaller farms, making jam is more practical than jelly.

> Reviewing code is important, but it's only 50% of the learning process, at best

I don't know about everyone else, but the code I reviewed as a Junior was high quality code I was expected to learn from. That's entirely different from doing code review on whatever CC outputs.

BitTorrent also enabled search engines to be built easily, which created discoverability. Unfortunately it's a much harder problem for git repos, especially when competing with GitHub search.

Oh, that's pretty cool! Now I can't decide whether that approach or one based on AT is better...

Is there really nothing like BitTorrent for git, or have we just not heard about it because of GitHub's network effects? It feels like this problem was solved long ago for binaries.

Things Fall Apart

Turning and turning in the widening gyre

The falcon cannot hear the falconer;

Things fall apart; the centre cannot hold;

Mere anarchy is loosed upon the world,

The blood-dimmed tide is loosed, and everywhere

The ceremony of innocence is drowned

Except ASML licensed the technology from the US Government, after the government labs built the first EUV fab in 2001. Not to take anything away from ASML...all the US companies that also licensed the tech failed to commercialize it, but the US Government blocked Canon and other Japanese companies from acquiring the technology. The entire reason ASML has the technology and nobody in Japan does is geopolitical.

Optics and photoresist materials too. The partnership developed the first EUV lithography in 2001: https://www.llnl.gov/article/27641/euvl-partnership-makes-it...

Let's not forget the really big gamble (inventing EUV) was made in the 1990s by US national labs: Sandia, Lawrence Livermore, and Lawrence Berkeley.

I mean, your brain has an order of magnitude more neurons than there are people on the planet. I think humans are just incapable of wrapping our heads around the sheer number of tiny things that fit in small macroscopic spaces.

Why would a machine need to make anything? Is a robot arm not a machine? How about a trash compactor? Are the 6 types of simple machines not machines?

> the relational model can subsume "graph" queries, but for all the reasons Codd laid out back in the 60s... network (aka connected graph) databases cannot do the latter.

Except network databases have little in common with graph databases...they're much more closely related to hierarchical databases.

I would say that Graph databases are now a strict superset of relational databases, not the other way around. In a graph database a node's named edge can naturally point to a node of any type or having any property schema. Doing this in a relational model requires one of several approaches that could only be classified as fighting against the model (or torturing it, as my PI liked to say).

Oh you're right! I was looking at the last documentation update timestamp, but the original release was 2006. That makes a lot more sense than Itanium support in 2021.

> Oracle® Database Platform Guide 10g Release 2 (10.2) for Microsoft Windows Itanium (64-Bit)

Well, I guess that at least confirms Oracle on Itanium (!?) still supported RAW 5 years ago.

I'm guessing everyone's on ASM by now though, if they're still upgrading. I ran into a company not long ago with a huge oracle cluster that still employed physical database admins and logical database admins as separate roles...I would bet they're still paying millions for an out of date version of Oracle and using RAW.

It seems like Claude has taken Github's place in terms of developer reaction to it being unavailable. It's like everyone forgot how they did things 18 months ago.

I'm so old I remember working on databases that were designed to use RAW, not files. I'm betting some databases still do, but probably only for mainframe systems nowadays.
