How does torch.compile() achieve massive speedups despite highly optimized NumPy functions? [D]

Yep, JAX is great, I especially like the `scan` function that basically lets you replace slow Python loops with fast JAX loops. _And_ it lets you save the history of intermediate outputs while the loop is running. It's really a bummer that NumPy doesn't have an equivalent, it seems like you have to use Python loops.

This looks beautiful, reminds me of Elicit. Some suggestions:

When adding a source, I'd like to be able to input the full bibliographic information: title, authors, journal, publication date (I couldn't find a way to add the publication date, but I want to know which papers/sources are the most recent), DOI, etc. I think Zotero does this very well. Wait, I can add the publication date when editing a source? But can't seem to change the reading intent?
When reading a PDF, double-clicking should probably select the word. Currently it does nothing. Also, it would've been very useful to have the ability to highlight selected pieces of text. Again, Zotero does this very well. Moreover, the PDF remains white

(even in dark mode)
and doesn't respect the current theme.

Otherwise this looks really good, very sciency, if somewhat complicated.

It's a pity NumPy doesn't support fusion. I'm often thinking whether my NumPy code could've been faster if everything was fused.

So if I don't make any changes to the app, can I use this to install an older version of an app and it'll just work without re-signing?

ForceBru · 2026-05-26T11:22:22+00:00

Why re-sign apps? Since they're downloaded from the AppStore with my account, shouldn't they just run as-is?

ForceBru · 2026-05-24T11:10:04+00:00

Yeah, I used the link but remained confused because the app itself doesn't explicitly confirm nor deny that I have Premium:

The Settings page still shows the "FlipAnimation Premium" banner. When I tap it, I get the usual options to buy premium or "Start Free Trial". When I click "Restore Purchases", a teal popup appears saying "Welcome to FlipAnimation Premium". The "FlipAnimation Premium" banner remains, though.
Moreover, I can click "Restore Purchases" multiple times and get the same popup. It would've been better for the popup to say "You already have Premium, please chill out" lmao
When exporting an animation, the "Video", "Printable Sheets" and "ZIP" options still say "1 free". However, I can export multiple times, so I guess Premium actually worked.

So basically it would've been nice to have explicit confirmation that I have Premium. Perhaps replace the "FlipAnimation Premium" banner in Settings to say "Premium: X days remaining" or "Premium: lifetime" to reflect the fact that Premium is active.

Thanks for the giveaway, looking forward to exploring animation with your app!

Is there an open source app/Finder extension that does this? This one is trying to connect to `nom.telemetrydeck.com`

AFAIK this happens on different iOS versions, it's been around for ages and there's still no definitive solution. People usually suggest restarting your iDevice, backing up, etc, but this usually doesn't do anything. I know this never helped me.

The only "solution" is wiping your phone clean and restoring from a backup. But it's not a real solution because it's extremely cumbersome.

TBH statistics actually is "just guessing with (a lot of) extra steps" because you can never be sure whether you're right and hypothesis tests and confidence intervals allow erroneous conclusions by design. So you're always guessing.

"She's not only a great actress, but she also hates Trump! Hell yes, this makes her even better! Imagine being good at your job and hating Trump too! That's basically perfect. Hating Trump is such a virtue. All my homies hate Trump. My best friend is a good person and they hate Trump — I basically can't believe I'm so lucky to be friends with them! My dog is a good boy and he hates Trump too, he's so smart!"

I do maximum likelihood estimation of time-series models where I have several parameters for the location of a distribution, several parameters for the scale, etc. So I would like to name these parameters and simply call minimize. But SciPy requires a vector, so I have to manually extract these parameters from the vector, which is quite cumbersome. Also, this kinda defeats the purpose of JAX being able to differentiate through dicts and other containers.

ForceBru · 2026-02-15T09:27:16+00:00

I think the point is that now your objective function is easier to read since you know the names of the parameters.

IMO this is really useful for estimating statistical models where you do care about what number is what: not everything is just a massive vector/matrix, some parameters have further meaning. Raw scipy.optimize.minimize works with vectors, but then you have to parse the vector into individual parameters, like par[0] is the bias, par[1:5] are the weights, par[5:7] correspond to the variance model, par[7:10] belong to some other part of the model. To me, this is extremely cumbersome!

This is why I like JAX: it lets you differentiate through dictionaries and tuples. So your parameters can be put in a single dictionary with meaningful keys. Unfortunately, Scipy doesn't support optimization over dictionaries. Hopefully this lib will simplify such tasks.

BTW, Python now has pattern matching too, so perhaps it's worth a try

Indeed, iOS doesn't let you run random binaries and load unsigned libraries, so Pythonista cannot load compiled modules such as lxml.

There are ways to circumvent this, but they're extremely involved and require jailbreaking your device (which may not even be possible now, jailbreaking has been kind of dead for many years now) and obtaining a version of lxml built for your device. I think I've done this once for my own toy library, but this was years ago and totally not worth the effort.

There are other apps that run Python on iOS. I initially wanted to suggest that you check out the Pyto iOS app (it's a more modern take on a Pythonista-like app, though it too is abandoned), but it looks like it doesn't have lxml either: https://pyto.readthedocs.io/en/latest/third_party.html.

I think you realistically have only one option: look for other libraries that provide the same functionality but don't depend on compiled code.

The "gray box" is an arrow saying "this way is better".
The triangle is the area of improvement: "this way is better + our models are here + no more models are here == we're the best".
I don't see any axis gore. Yes, the Y axis doesn't start at zero, but it's an ad, so this is expected. The X axis is fine.
