If I used a racecar to go 25mph in a residential neighborhood, I’d make a similar conclusion.

I think that figure (haven’t verified it but assuming it’s true) isn’t complete. It hides who and where those people are - for example, I imagine art history skews towards higher ranked schools in the first place.

If we’re defining on-prem as fitting in a rack - then every frontier model can be hosted on-prem.

Now this might not be the most cost effective (and may require a bit extra power), but you only need a datacenter for training or cost optimization.

This statement is well known to be incorrect for at least a year.

If by "happened to" you mean pour significant resources for well-over a decade on many different AI research groups then yes, that's accurate. Depending on your definition of AI, it might even be two decades.

In fact, OpenAI was founded largely with the direct goal of preventing Google from being the sole winner in AI...

This isn’t quite accurate. Data weighting is quite important in pretraining.

From a user perspective it is nice to know that the person decoding will likely support a given format, both now and in the future.

More use cases for a single popular format makes this more likely.

I really wish that there was an “almost yolo” mode that was permissive but with light restrictions (eg no rm), or even better, a light supervisor model to prevent very dangerous commands but allow everything else.

I can assure you that lacking knowledge in DPO (and especially GRPO it’s just stripped down PPO) is not a dealbreaker.

This seems like the perfect case for legislation that starts out targeting higher volume devices/larger companies and lower over time.

I don’t see why the industry couldn’t move to providing this documentation/full source over a few years.

A lot of developers (including myself) don’t want to notarize/sign their binaries that they want to run on their own machine(s).

Seconding another commenter. I went to a state-school (maybe in the top 5 US state schools) and got an offer without any elite background.

Related: I've been pretty frustrated with cursor that you can't call any APIs directly, and it all has to go through their backend. Along with this, they have essentially refused to fix bugs in their custom API key page for months, forcing you to use their "1st party" tokens.

upbeat_general — Thu, 13 Mar 2025 06:05:27 +0000

Here’s the simple reason why this is not the case:

If you provide the 6DoF trajectory (+ gripper joints), a lot of robotics (manipulation in particular) is basically solved. The problem is, we don’t have these good trajectories.

Sure, joint space is commonly used for learned policies, but cartesian space isn’t uncommon either.

IK is really just not a major focus on the learning side of robotics because it’s not the problem. The problem is we don’t know what to do even at the slightly higher level.

Not a war crime, China has plenty of agriculture.

See the Cuban missile crisis. It is an act of war but certainly not as escalatory as direct attack.

The challenge here is not IK. Sure, you don’t need IK if your policy directly operates in joint space but this isn’t the motivation for doing RL.

IK to my knowledge is well known in every setting I am aware of.

upbeat_general — Thu, 20 Feb 2025 01:15:08 +0000

Has anyone used Typst for academic conferences/journals?

To me it’s sorta like CSS where the availability of templates is more important than the core language (at least for people lacking design abilities).

It’s less reproducible than docker (assuming the pip usage is correct). Docker specifies a lot of OS properties that UV ignores.

That being said, UV is great.
