Did you implement formulas from scratch, or used a third-party lib?

Probably better to use partitioned table and drop old partitions.

> We had createScheduledPosts.ts that would run every 15 minutes, scan our table of scheduled posts and create any that needed to be published.
Why not set the publication_date when you create a post and have a function getPublishedPosts that fetches a list of posts, filtering out those with a publication_date earlier than the current date? With this approach, you don't need cron jobs at all.

Is it possible to use batch mode with fine-tuned models?

I think this is a fabrication by the journalist. Overall, it seems to me that there was an ideological agenda behind this story. In the USSR, no topic could cause a stir in major media outlets without an ideological directive.

Does it implement JS standard library, for example Map, Set etc?

So, it's impossible to transfer a value from one machine to another if there's no network connection between them? How did this extremely trivial observation become a well-known theorem?

I am developing an online IDE capable of visualizing a program's call tree. Within this IDE, users can select a node in the call tree to observe detailed information, including function arguments, return values, local variables, and intermediate expressions. Additionally, the IDE features a time-travel engine that displays the values of mutable objects at the specific moment when a particular function and statement were executed.
You can try it online here: https://app.leporello.tech/?example=fibonacci

I am building an IDE for functional JS. It can visualise a call tree of a program, helping to understand execution of recursive functions

>> you can use print statements and step debugging, together, at any point in time in the recording
I am working on something similar. I am building an IDE that allows to jump from the line printed by a console.log call to a corresponding code location, and observe variables and intermediate expressions.
It also displays a dynamic calltree of a program, allowing to navigate it in a time-travel manner.
Currently it only supports pure functional subset of JavaScript, but I am working on support for imperative programming (mutating data in place).

There was a similar tool developed by Oracle called mod_plsql, which served as an Apache web server module. As far as I remember, it allowed you to configure a mapping from a URL to a stored procedure. These stored procedures could receive HTTP request parameters and return HTML content.
I've always felt that this approach is the right way to build applications. Application servers seemed like an unnecessary layer to me, essentially serving as intermediaries that merely passed data from the database to the browser. In the past, they played a more critical role in generating HTML, but nowadays, application servers are primarily used for handling APIs. Consequently, they often lack meaningful tasks to justify their existence.
Having your code closely integrated with the data also has the benefit of improving performance.

Leporello.js: https://leporello.tech/
Leporello.js is an interactive functional programming environment designed for pure functional subset of JavaScript. It executes code instantly as you type and displays results next to it. Leporello.js also features an omnipresent debugger. Just position your cursor on any line or select any expression, and immediately see its value. Leporello.js visualizes a dynamic call tree of your program. Thanks to the data immutability in functional programming, it allows you to navigate the call tree both forward and backward, offering a time-travel-like experience.

Shameless plug: I have always been fascinated by edit-and-continue and I build a JavaScript IDE centered around it.

>> How does it deal with patterns from popular frameworks or libraries that are borderline frameworks. React, Vue, Express, NestJS etc.
React is a great fit for Leporello.js. There is an example of React TODO app that you can write and debug in Leporello. It is showcased in the video. You can play with it yourself if follow the link https://app.leporello.tech/?example=todos-preact
Speaking about backend frameworks, basically you code is a function Request -> Response. How do you organize your code is up to you. You can code it in a functional manner. What is great about Leporello, is that it remembers all the calls your app made to databases, other microservices and external APIs and allows to debug them in a time-travel manner, seeing requests and responses. You can run your code once, and then debug and navigate it forward and backward, seeing runtime values that were generated when your code was executed. It a huge time saving, especially when external resources are slow and may require complex setup or teardown before or after being called.
>> It feels like leporello has to store a lot of possible branch-outs of the state
Could you please clarify, what do you mean by branch-outs of the state?

>> That is, how leporello handles a codebase that's partially written in freestyle JS and not the subset that leporello specify handles?
Leporello is based on the idea that you can have much more powerful dev experience (time-travel debugging, better debugger UX) if you adhere to functional code. Look at the recent news from Jetbrains [0]. They presented predictive debugger for their .NET IDE. They called it "a game changing look into the future" and it is actually a huge improvement of ergonomics. But with FP, you get predictive debugger for free. It is just a trivial consequence of not having data mutations. So inside the function, each name is binded to single immutable value.
If you have freestyle JS, then Leporello is not a good fit for you. It requires some buy-in from a developer. The good thing is that you still write plain vanilla javascript, without non-standart extensions that require some kind of transpilation.
