It's essentially ObservableHQ, but with Datalog instead of JS while reusing the same plotting libraries. Genius.

DDnD — Development, Deployment and Delivery.

https://www.inkandswitch.com/crosscut/

Очень крутая попытка сделать визуальное программирование в смысле визуального моделирования, а не очередной неуклюжий GUI для представления графа потока данных и абстрактных функций. Поэтому Crosscut работает на основе непосредственной манипуляции конкретными объектами. Конечно, наглядно-образное мышление супротив абстрактного работает только до определённого предела, но при наличии компьютерной поддержки этот предел отодвигается удивительно далеко. Обратите внимание на "bidirectional evaluation".

Кот выкатил тяжёлую ортиллерию.

Pretty cool Vangelis' Blade Runner vibes. 😁

Судя по https://algorithmsbook.com/#outline — очень крутая книга.

A proof of uncountability of Reals for those who don't like Diagonal Argument but like Games. 😁

Yay, they've uploaded the recording! A fascinating but puzzling topic. Bayesian priors update is not as simple as LessWrong fans make it sound. 😁

Every Data Analysis platform attempts to expand until it includes a Spreadsheet. Those platforms which cannot so expand are replaced by ones which can.

Or maybe

Any sufficiently complicated Data Analysis platform contains an ad hoc, informally-specified, bug-ridden, slow implementation of half of Excel.

(Paraphrasing https://en.wikipedia.org/wiki/Jamie_Zawinski#Zawinski's_Law and https://en.wikipedia.org/wiki/Greenspun%27s_tenth_rule if you didn't recognize them at once. 😊)

Though curious thing about this tool is that it generates Python code that performs transformations you specify in the spreadsheet. Advantages are obvious. Would be super cool if it could synchronize the other way round, but it can't unfortunately.

In other news. Lawrence Paulson started a series of introductory posts to Isabelle/HOL: https://lawrencecpaulson.github.io/2022/05/04/baby-examples.html

WOW this is mind-blowing: http://liamoc.net/holbert/
A browser-based notebook-style theorem prover for higher-order logics. Aimed at educational applications, and as such can switch between more formal tree-like and a book-style natural deduction proofs presentation.

Here's a notebook about MLTT: http://liamoc.net/holbert/?https://gist.githubusercontent.com/brendanzab/1b4732179b15201bf33fed6dbca02458/raw/mltt.holbert

Rust's Crates.io выходит на уровень NPM и PyPi, так сказать. Печально, но это действительно был всего лишь вопрос времени.

Но моё внимание, как обычно, привлёк следующий пассаж:

When the function was called, it checked whether the GITLAB_CI environment variable was set, and if so it downloaded a binary payload into /tmp/git-updater.bin and executed it.

Это про функцию Decimal::new. Да, она должна просто создавать число.

И кому только может понадобиться разделять чистый код и эффекты в системе типов языка? Зачем? Бесполезная бюрократия на ровном месте!

Alan Kay is at his shit again! That's year-old news actually. Some quotes.

"A little company named Adobe" was founded by the guys who invented the PostScript. Insane.

If I ever have enough money to invest in a startup, my first question will be "what have you invented?" Adobe was founded by the guys who invented PostScript, Google was founded by the guys who invented PageRank, what the fuck have you invented?!

"Against all applications".
Not in "Appstore Applications" sense but in "Job Applications" sense.

Writing portable code is hard: https://www.chemistryworld.com/news/structures-in-more-than-150-papers-may-be-wrong-thanks-to-nmr-coding-glitch/4010413.article

The error is the result of a simple file sorting problem. On operating systems without default file name sorting, the script fails to match the files containing a conformer’s free energy with its chemical shift – leading to an overall wrong value.

Which meant the script worked fine on Windows while producing incorrect results on GNU/Linux. This jeopardizes some 150 chemistry papers.

Good news: worthy new ideas are not harder to find in all areas (art, science, business and what not). Though I suspect ideas might become harder to develop to a "competitive state".

Bad news: doing science indeed becomes harder for all sorts of wrong reasons. 😒

Jupyter-like notebooks for Elixir but with some twists.

It looks like they aim not at Data Analysis but something akin to DevOps tasks automation. Though they have SQL and visualizations too.

Speaking of which their approach to Widgets (they call them Smart Cells) is curious. Smart Cells are basically a UI to generate some Elixir code which gets then executed in a usual way. At any point you can replace the UI with the code and start rewriting it manually however you please.

Integrated package management through Mix API seems nice and much better than separately installing libraries and importing from different places.

In the end they're building 100% source code backed notebook interface. Well they got me hooked to a degree. 😊
