JavaScript Updated 2025-07-16

The language all browsers converted to as of 2019, and therefore the easiest one to distribute and most widely implemented programming language.

Hopefully will be killed by WebAssembly one day.

Because JavaScript is a relatively crap/ad-hoc language, it ended up some decent tooling to make up for that, e.g. stuff like linting via ESLint and reformatting through Prettier is much more widespread than in other languages.

JavaScript data structure are also quite a bit anemic, which makes libraries such as lodash incredibly popular. But most of that stuff should be in the stdlib.

Our JavaScript examples can be found at:

Node.js example: examples that don't interact with any browser feature. We are just testing those on the CLI which is much more convenient.
JavaScript browser example: examples that interact with browser-specific features, notably the DOM

Ciro Santilli's favorite music genre.

Ciro's 2020 perfect Friday evening: jazz fusion + study quantum field theory on an Amazon Kindle. Ahhhhhh.

JCVI-syn3A Updated 2025-07-16

NCBI: www.ncbi.nlm.nih.gov/nuccore/CP016816.2

essential metabolism for a minimal cell (2019) mentions:

JCVI-syn3A, a robust minimal cell with a 543 kbp genome and 493 genes, provides a versatile platform to study the basics of life.

Based on JCVI-syn3.0, they've added a few genes back to give better phenotypes, including slightly faster duplication time. Because the development cycle time is your God is also true in biology.

As of essential metabolism for a minimal cell (2019) it had only 91 genes of unknown function! So funny.

JCVI-syn3B Updated 2025-07-16

www.biorxiv.org/content/10.1101/2022.09.19.508583v1.full

CVI-syn3B strains differ from JCVI-syn3.0 by the presence of 19 additional non-essential genes that result in a more easily manipulated cell. JCVI-syn3B additionally includes a dual loxP landing pad that enables easy Cre recombinase mediated insertion of genes

It is also interesting to see how they are interested in co-culture with HeLa cells, presumably to enable infectious bacterial disease studies.

At biology.indiana.edu/news-events/news/2023/lennon-minimal-cells.html (2023) they let it re-evove to it it would regain some fitness, and it did.

Jean Baptiste Perrin Updated 2025-07-16

This seems like a cool dude. Besides a hardcore scientist, he also made many important contributions to the French education and research system.

Jeff Bezos Updated 2025-07-16

Jeff has spoken a lot in public about Amazon, perhaps even more than other comparable founders, see e.g. Section "History of Amazon". Kudos for that.

Jena SPARQL hello world Updated 2025-07-16

They have a tutorial at: jena.apache.org/tutorials/sparql.html

Once you've done the Apache Jena CLI tools setup we can query all users with Full Name (FN) "John Smith" directly fom the rdf/vcard.ttl Turtle RDF file with the rdf/vcard.rq SPARQL query:

sparql --data=rdf/vcard.ttl --query=rdf/vcard.rq

and that outputs:

According to jercos the transaction was finalized over IRC chats. Jercos was 18 at the time of the transaction.

youtu.be/HqWWoaA8pIs?t=1053 Fairchild had won the first round of a Minuteman contract, but lost the second one due to poor management

Jimmy Wales Updated 2025-07-16

One thing to note is that Jimmy was a finance worker before starting wikipdia, e.g. he had capital to hire Larry Sanger.

Maybe that's the way to go about it, make money first, and later on change the world.

Starting just after the beginning of the Internet can't hurt either. Though tooling must have been insane back then.

Jim Simons Updated 2025-07-16

Ciro Santilli's wife, who was frustrated with academia at some point, admires the fact that Simons managed to make infinite money, and then invested back in actual science, e.g. through the Simons Foundation.

Congratulations on the second prize. With the third you get to keep the king!
The king asked my mother [Bardeen's son speaking]: "Where's he family"? The mother answered: "Well, they're at home or school". And the kind replied: "Well, next time, bring them!"
