The price at IPO will obviously be influenced by expectations of a future purchase by index funds... as an analogy, if it became public knowledge that next week, 1,000,000 people would all be required to buy gold, the price of gold would go up today, not next week

I was curious so I gave it a try and switched my photo editing site [0] to jpegli. Here's a comparison between a 29kb avif file (left) and a 146kb jpeg file (right), as produced by my site: https://files.catbox.moe/wdo9gf.png . The avif looks much better to my eye, and is of cource much smaller

Hmm, I don't think so. I think at a fixed file size, chroma subsampling usually allows you to have fewer noticeable artifacts. Humans are so much more sensitive to luma that it doesn't make sense to treat it equally to chroma with respect to lossy compression. That said, if you don't like it, AVIF supports 4:4:4 just fine.

In my tests, AVIF beats PNG easily for lossless compression of actual photographs (for things like charts and screenshots, PNG wins of course). And for lossy, it's much smaller than jpeg and supports HDR unlike WebP. So if you need HDR and are doing lossy compression on the web, it's your best option as far as I know.

I love HDR, but until recently dynamic HDR content was hard to render in the browser. But now, with browsers shipping support for WebGPU and canvases with extended color spaces, it's actually feasible.

So what I wanted to was make an image editor capable of doing the simple edits I often need to do, but with full HDR support, which is rare in browser editors. Turning up the brightness on an HDR-capable monitor is a great way to see what your monitor can do :P

I tried to go overboard in every way I could. So brightness/saturation/hue adjustments use the okLCH color space, and there's an option to do a "content-aware resize" with seam carving, which is fast because it's parallelized using Sam Westrick's triangle-blocking algorithm [0].

Also, the site supports importing HEIC photos as taken with an iPhone, which is surprisingly hard to do correctly. Libraries like libheic don't fully support the format used by iPhones, so if used naively the HDR colors come out wrong. I'm working on a blog post about this, but the short version is that you have to use ISO 21496-1 gain map composition (which isn't even what apple documents). I'm pretty sure that pictolab is the *only* website that allows you to convert HEIC to JPEG or AVIF without messing up the HDR.

There is also a local background-removal model. Enjoy!

Once they get quicker to train, I expect this to be a popular use of them

If states all worked together, they could plausibly prevent this race to the bottom by agreeing on a universal sales tax minimum, but there are many obstacles to that as well besides some vague sense of "lobbying". You'd want all states to work cooperate on their minimum tax, but every state has a big incentive to break from the cartel and offer lower taxes in exchange for getting all the datacenters built there. There are lobbyists who are working against this, but it's not just meta and google, it's also local utility companies and construction/trade unions (who all want their state to defect and be the one to get all the new money and jobs)

I also want to shorten the intro, thanks for the feedback

The basic idea is to combine spaced repetition (like Anki) with comprehensible input. So the app tracks what you know and tries to give you sentences that are at your level and that reviews what you need to review. The sentences are pulled mostly from movies and TV shows so you get to review every word in a natural context and with realistic usage. I find this much more fun than just looking at flashcards.

Currently I support French, Spanish, German, Italian, and Portuguese. I also have early support for Russian and Korean.

I originally made it to help myself learn French, but my friends kept asking to use it, so I thought I'd add some more languages and release it publicly. I have friends using it for German, Spanish, Italian, and Korean right now. I'm not interested in making money from it right now so there's no monetization.

P.S. For people who like pimsleur, you can also choose to review words from any pimsleur lesson in Yap.
