My experience has been that anything less than a 4-bit quant has a tendency to go off the rails. There’s a threshold of coherency that is being crossed somewhere internal to the model I guess. Try the same prompt with a larger quant (even i

That README hits all my “this is authored by an LLM” instincts. I presume the codebase is also written by an LLM?

In the video I linked Felix only talks about DFUS, which has no value tilt. He may talk about their other funds in other videos, but not this one.

Most of the Dimensional ETFs seem to be following some kind of value investment strategy where they take an index but nudge it a bit by some value factor which is claimed to be based on long standing research. It wouldn’t be surprising if t

Dimensional runs a bunch of ETFs which are effectively US & world equity index trackers that don’t slavishly follow the indices & can therefore avoid being forced to buy into IPOs or index updates. E.g. DFUS is effectively VTI (IIRC

This was a laptop, so cooling was very constrained. The fans can only be so big & you can only shift so much air in & out of a MacBook. I presume Apple knew perfectly well but wanted the halo product to sell to those people who will

The i9 was notorious. Would thermally throttle almost instantly & for any sizeable build job would end up slower than the i7 IIRC. Intel really made themselves unpopular with Apple during that period.

I know this is kind of old hat by now, but it kind of blows my mind that I can upload a hand drawn decision tree & get a transcribed dot file back on consumer hardware using a pile of linear algebra that wasn’t even particularly special

Clover is a nitrogen fixing plant - used to be that you’d plant clover for a year in between other crops to make your soil fertile again. (It’s the bacteria in the roots that do the actual nitrogen chemistry.)

In the UK the all in cost of a PhD student starts somewhere around £45k once you include overheads I believe. If you need expensive lab support then it probably goes up from there. So about $75k for the bottom end? The quoted numbers sound

Only the M4 Pro Mac Minis have faster RAM than you’ll get in an off-the-shelf Intel/AMD laptop. The M4 Pros start at $1399. You want the M4 Max (or Ultra) in the Mac Studios to get the real stuff.

I honestly have no idea! I strongly suspect the systems that are uppercasing everything were not written to handle unicode in the first place though.
