#posit — Public Fediverse posts

Positron is Posit’s newer IDE for data science, built for R and Python. Posit Assistant brings AI into the workflow.

Join Kia Mack on 13 August for live demos comparing Positron with RStudio and testing Posit Assistant on everyday data science tasks.

See where the tools help, where they get in the way, and whether they belong in your workflow.

#RStats #Python #Posit

@juliasilge Thanks for your input, Julia. I think your reframing is a meaningful one. Perhaps it might be useful to include that on the Posit website so when others search for the #Julialang extension for #Positron, they will have a more nuanced understanding of the kind of effort and support for Julialang that #Posit has in mind. Thanks for the reframing and helping me see the Julia extension effort in a new light (i.e. the lack of institutional knowledge to robustly support Julia in Positron).

@adamhsparks I was thinking the same thing. When #Posit first came out with #Positron, I was hoping they would embrace more or less the #Jupyter (#Julia + #Python + #R) philosophy of promoting the 3 core data science #EDA languages.

A bit disappointed that #Positron isn't embracing #Julialang as a native language in their IDE. I think #Julia is a strong contender for exploratory data analysis #EDA. I do appreciate the minor support for a very alpha extension, but it's clear #Posit doesn't have real desire to support Julia. It's a wonderful language!

Каталог из 83 форматов с плавающей точкой, который сам себя проверяет

Если вы ловили расхождение точности между двумя реализациями одной сети, то знаете это чувство: один matmul на двух устройствах даёт разные числа, и непонятно — это баг, bf16 округлил или формат не тот. Две команды меряют один результат разными линейками. Я сделал одну линейку с точными насечками: машинно-проверяемый каталог из 83 числовых форматов в 13 кластерах. Для каждого — разрядка битов, смещение, кодирование inf/NaN/субнормалей и общий якорь проверки 0x47C0. Из одного источника истины генерируются Markdown, JSON, Python, Rust, C и RTL для кремния. У каждого формата стоит метка зрелости: 51 Verified, 12 Historical, 11 Experimental, 9 Open. И отдельная ось — граница RTL: где правило e = round((N−1)/φ²) ещё работающее железо (GF16 доведён до кремния), а где уже гипотеза (GF512/GF1024 — экстраполяция без строки Verilog). Внутри — лестница зрелости форматов, связь с IEEE P3109 и реальный баг в умножителе, который нашли только потому, что под форматом есть железо. Как устроена линейка

I've just tried Posit Assistant on the free plan and must say, I'm impressed. Using the super-cheap Gemma 4 26B model (10% cost of Sonnet) on free plan it worked instantly. Hats of to the #posit team for integrating this into RStudio and allowing people to test with free plan!

@JorisMeys One word for this is *unprofessionality*.

RE: https://mastodon.social/@coatless/116514621992544197

Quite unfathomable that Posit basically pointed a Claude bot at an open source project and essentially copied it almost line by line without proper attribution.

The "skills" of LLM too often turn out to be copying someone elses work.

This is sad but unsurprising.

Pues ahora Posit ha metido IAG a RStudio, al menos en su versión de pago. Cosas muy necesarias.
Se agradece que sea con suscripción, así no tengo que molestarme en buscar la opción que lo desactiva (pero voy a mirar, por si acaso).
Sí, incluyo esto en el enmierdamiento, porque sólo puede resultar en mal.

My latest blog post explores a Multi-Material Thermal Analysis using HYPRE BoomerAMG with a custom POSIT accelerator called Uttunga, and compares it to the x86 IEEE 754 standard.

Well crud. Looks like #Posit has gone full #enshittification too. I hope there's a good archive of previous versions that don't have this crap in them. So disappointing, though I can't say that I'm surprised given their direction over the years.

Might publish a blog or two in a few weeks about my work with OpenFOAM, different profilers, and an implementation of an LBM CFD kernel on RISC-V with POSITS.

What a great company to be working for. Learning so much!

Reminder that #Posit the creator of #Quarto works with #Palantir, and this is why we can't have nice things lol https://posit.co/blog/posit-and-palantir/

Is there not enough other clients for data science that you can't resist working for the evil ones??

I do like quarto tho :/

Most Posit issues do not start with a visible failure.

They build up through configuration choices, version drift, and infrastructure decisions that no longer fit how the platform is used.

Over time, this leads to unstable deployments, timeouts, security concerns, and harder upgrades.

At Jumping Rivers, our Posit Health Check reviews configuration, servers, versions, and security to surface risk early.

So today I vibe coded a #positron /vscode extension to detect SQL strings (in R scripts) called by {DBI} and other common packages with functions that call SQL strings, it then provides code completion/suggestions. It also has super buggy code highlighting. Oh and it only really works with #duckdb. It's so rough right now but I feel like it would be amazingly useful if it worked well, does anything like this already exist / can someone build a stable version of it please 🤣 ? #rstats #posit

Still no #CRAN logs from @posit.co is there a known issue? Thanks #R #RStats #CRAN #CRANLogs #Posit

Does anyone have experience regularly developing inside browser-based instances of VS Code or derivatives such as the Positron integrated development environment by #Posit? It seems to work well but some shortcuts that would work locally, like Ctrl+PgDn behave different locally, changing the browser window not cycling the IDE element. But overall, impressed! #DataScience
