Very good timing in my opinion, especially if you look towards AM4 and AM5 platforms from AMD. Lots of PCI lanes available that you can throw towards GPUs and tons of other i/o like fast nvme pci storage or usb c ports

I wrote my own version of this many years ago for a music app I built and daily drive, the code hasn't been updated in years haha kind of perf sensitive due to rendering thousands of tracks in a virtualized table. Could use some love

#FreeJavaScript: We responded to Oracle's Motion to Dismiss our fraud claim.

Oracle argues submitting one valid specimen excuses submitting a fraudulent one.

Our position: one legitimate submission doesn't erase another fraudulent act.

I made a midi controller with Svelte.
This thing can be played by your computer keyboard, top two rows for keys, bottom row for chords.
In locked key mode, you can change the key and play all chords within that key.

This is probably a p0 value add for phoenix

In this case what do you do with the final output from deepseek? Does it let you stop running after the reasoning is complete?

Could probably do some interesting evaluation workflow where you perform the steps in the video, but at the end compare 3.5 + reasoning to deepseek's final output

Is there a way to "report" posts that trigger keywords but don't actually fit the feed? I've had a few instances of posts that are _very_ unrelated to web dev but contain phrases like "js" or "css" so I understand why they made it in πŸ˜…

We use off screen canvases quite a bit so good shout

I'll give the GitHub repo a look and report back if we're able to make it work. Very cool project πŸ‘

This is so extremely relevant to my near term interests πŸ˜€ my friend is building a physically rendered game using JS and we were just discussing options for shipping it outside of a browser with minimal changes. Only uses canvas APIs and everything else is written from scratch

I've had exactly the same takeaway. Both langchain and vercel have a vested interest in improving and optimizing their js AI libs however as they build more and more first class AI services into their own platforms with js. Presumably they are dog fooding heavily πŸ˜…

What are you rendering to? Presumably canvas doesn't work when compiled to wasm. Have been curious about this

I keep saying this, JSX is my favorite side effect of react adoption. It really gels with my intuitive understanding of how an interface should be modelled

I struggled for a long time to understand why people would open source "serious" software. Over the years I've come to understand that the code alone is not some closely guarded secret that needs defending, it's only the output of a dedicated team executing a vision, and that cannot simply be copied
