They should rewrite it in rust again to get another 3x performance increase /s

There are explicit residual connections in a transformer block. Look up "residual connections" in Google images and you will see.

Thanks for the explanation. Honestly, your explanation is better than the entire video. - I watched it in full and got really confused. I completely missed the part where he said the light is pulsing at 30kHZ and was really puzzled at how he is able to move the mirror so fast to cover the entire scene.

Does using a constraint solver actually solve the question under the time ... constraints?

If not, how can you claim you have solved the problem?

Where do you even get the $3,000 standing desk? I am don't even compare prices and I got mine from Amazon for $200-$300. Sure the quality might not be the best but I just can't see there are people buying $3000 standing desks.

> And as someone who's into spy stories, I know that a big part of tradecraft is of formulating your questions in a way that divulges the least about your actual intentions and current information.

Not necessarily disagreeing with you, but if everyone started doing this, we will be in XY problem city.

I don't think they used AI nor claimed to have used AI. The interviewee just said "We monitor abnormal deformation of the buildings in real time."

Yeah, the commonjs to esm transition has been the python 2 to python 3 transition of JavaScript, except the benefits are limited (at least compared to the hassle created).

There are many libraries that have switched to esm only (meaning they don't support commonjs), but even today, the best way to find the last commonjs version of those libraries is to go to the "versions" tab on npm, and find the most downloaded version in the last month, and chances are, that will be the last commonjs version.

Yes, in a vacuum, esm is objectively a better than commonjs, but how tc39 almost intentionally made it incompatible with commonjs (via top-level awaits) is just bizarre to me.

This comment might be one of the meanest comment I have ever seen.

New comment by SCLeo in "Supercharge SQLite with Ruby Functions"

SCLeo — Wed, 29 Jan 2025 09:00:08 +0000

This explanation is extremely misleading. For many of my projects, vast majority of the operations do not use the database . And the few that does, contains long running huge joins/aggregates. Using the sync API is just straight up terrible because the task will block literally everything else that does not use the db in js, meaning generating a report in the background can literally prevent you from handling any requests. (I did end up using better sqlite 3 because they are personal projects and getting stuck for 2 seconds when the scheduled report generation happens is ok ish for the a few people using it. But I will not consider using better sqlite 3 for any future projects)

I believe they wrote their own image handling and did not contribute back to llama.cpp.

I feel so stupid to left out h1-h6. Also completely forgot about the entire table related tags.

I think most people just start typing "HashM..." and trigger auto complete, and hit tab to import and auto complete HashMap.

If you have a namespace, can't people just globally-claim namespaces instead? like serde/serde or something similar. I feel if you really don't want people claim whatever they want, you have to do the Java package style where namespaces are tied to domain names.

SCLeo — Tue, 03 Oct 2023 15:28:23 +0000

I think all other methods require a reflow as well (internal or external). Because at the end of the day, you still need to measure the height of the text before rendering a larger box.

In all seriousness, what fuck is going on in Fandom? It has soooo much ads!

I just turned off my ad blocker and literally only 21% of the page is content and the remaining is ads. After 2 seconds, it got replaced by a full screen ad. What? How? What are the people at fandom thinking? This is completely unusable without adblockers!

Don't believe me, here are the screenshots I just took: https://imgur.com/a/sNg3IlJ

New comment by SCLeo in "Petition to stop France from forcing browsers like Firefox to censor websites"

SCLeo — Thu, 17 Aug 2023 14:05:30 +0000

I am actually not sure if this is satire, but in case it is not, I don't think Firefox is in the position to boycott France, when Google Chrome exists, and is very likely to comply with the new law.
