Our biggest launch in years: nbdev2, now boosted with the power of @quarto_pub!

Use @ProjectJupyter to build reliable and delightful software fast. A single notebook creates a python module, tests, @github Actions CI, @pypi/@anacondainc packages, & more
fast.ai/2022/07/28/nbd…
What can you create with #nbdev with @quarto_pub? Well, for starters, check out our beautiful new website.

Created with nbdev, of course!

nbdev.fast.ai
That website is generated automatically from the notebooks in this repo.

Take a look around -- all the things you'd hope to see in a high-quality project are there. It's all done for you by nbdev. For instance, see the nice README? Built from a notebook!
github.com/fastai/nbdev/
nbdev v1 is already recommended by experts, and v2 is a big step up again.

"From my point of view it is close to a Pareto improvement over traditional Python library development." Thankyou @erikgaas 😀
Here's an example of the beautiful and useful docs that are auto-generated by nbdev+Quarto.
nbdev.fast.ai/merge.html
Here's an example of an exported function in a notebook cell. This is automatically added to the python module, and the documentation you see on the right is auto-generated.
nbdev.fast.ai/merge.html#nbd…
Every time we update a notebook to change the docs, library, or tests, everything is checked by @github Actions automatically
Here's the @pypi pip installer that's auto-generated. See the description? That's created for you from the notebook you use for your documentation homepage (just like the README, and the description for your conda package)
pypi.org/project/nbdev/
I've barely scratched the surface in this brief tweet thread! For much more information, take a look at the blog post authored with @HamelHusain
fast.ai/2022/07/28/nbd…
This launch wouldn't have been possible without some amazing people. I'd especially like to highlight Hamel & @wasimlorgat, who made nbdev2 a far better product than it would have been without them, JJ Allaire @fly_upside_down & the @quarto_pub team, & the @fastdotai community

Wow, actual grown men are still doing the "I asked the LLM about itself and it said" thing.

In 2025.

Folks, LLMs don't know anything about how they themselves are built or deployed, unless they've been explicitly programmed with that information (which they almost never are). Image
If you are using a Chinese cloud based service hosted in China, then your data will be sent to a server in China.

Because that's how computers work.

It's not a conspiracy.
I hadn't heard of this guy before, but apparently he'll teach you how to learn AI.

Cool. Image

I've recently been surprised to discover that a few of my friends are choosing to use nicotine to help them with focus, even though they are not ex-smokers.

I decided to look into it, and it turns out that there are documented health benefits of nicotine for some people. 🧵
I specifically looked into nicotine for ADHD, since, at least among children, ADHD and giftedness go hand in hand statistically (which would apply in adulthood too), and because focus was mention as an area where nicotine can be helpful.
There is a great overview below. But "Very surprisingly, there are… no further… studies.

Research into active ingredients… is expensive.

In addition, nicotine has a very poor image… which impairs its marketability"

I'll get straight to the point.

We trained 2 new models. Like BERT, but modern. ModernBERT.

Not some hypey GenAI thing, but a proper workhorse model, for retrieval, classification, etc. Real practical stuff.

It's much faster, more accurate, longer context, and more useful. 🧵 Image
ModernBERT is available as a slot-in replacement for any BERT-like model, with both 139M param and 395M param sizes.

It has a 8192 sequence length, is extremely efficient, is uniquely great at analyzing code, and much more. Read this for details:
huggingface.co/blog/modernbert
Seven months ago, @bclavie kicked things off, and soon @benjamin_warner & @antoine_chaffin joined him as project co-leads. I don't think anyone quite knew what we were getting in to…

It turns out that training a new, SoTA model from scratch is actually pretty hard. Who knew? 🤷 Image

Oh wow. This is gonna be super tricky to figure out what to do now.

There isn’t any easy automated way to install a full deep learning stack from scratch after this change afaict.
I wonder if the @PyTorch analysis behind this is mistaken. I suspect most of the pypi installs they’re seeing are from CI and similar. Conda installs are the standard for end user installation of PyTorch afaik
@PyTorch Conda aggressively caches installs so looking at relative download numbers won’t give a great sense of real usage.

New version of sqlite-minutils (our stripped-down fork of @simonw's sqlite-utils) just released.

It has a fairly major and quite interesting change.🧵
github.com/AnswerDotAI/sq…
For the 1st time, we've decided to significantly change behavior from sqlite-utils: we've changed from using Python DB API transaction behavior, to original sqlite behavior.

That is - we've set `isolation_level` to 'none', and removed `with db` clauses.
docs.python.org/3/library/sqli…
Original sqlite is in "autocommit" mode at all times, unless/until you explicitly begin a transaction. I find this behavior convenient and intuitive, so sqlite-minutils now sticks to it too.

Today @answerdotai is proposing `/llms.txt`. This is a file you can use to tell models where to find LLM-friendly content for your website.

It provides background information, along with links to markdown files providing more detailed information.
answer.ai/posts/2024-09-…
We're providing a website with details of the proposal, & javascript and python parsers. There's also an example of how to incorporate llms.txt into an editor--rather than weight into the emacs vs vim vs vscode wars, we picked ed, the standard text editor
llmstxt.org
Today websites are not just used to provide information to people, but they are also used to provide information to large language models.

For instance, language models are often used to enhance development environments used by coders.
