Anyone else read the title and think someone found a way to spot early stock market sentiment shifts by analyzing options patterns?

Oh boy. I wonder how many other companies that have previously been lax about validating that cert revocation is handled correctly by their devices are going to validate the eMudrha cert revocation and discover that they are not, in fact, handling revocation correctly. Yikes.

I struggle with approaching this as I do with many quants, in that there's not really a good measurement of how lobotomized by quantization they are other than "a bit but it's not too bad". Ternary weights immediately make me think "unusably quantized" but I'm presuming that's not the case if someone's standing by this release without massive caveats.

I struggle with deciding whether to take the speed hit on q8 vs q6; I wish it was more standard to benchmark quants or have some way to indicate how much intelligence you're leaving on the table.

I don't mind waiting twice as long for twice as smart; I don't want to be passing up the opportunity of 4x speed-up with 98% intelligence retained. But I have no way to differentiate which is which with quants in any vaguely objective way.

Frustrating, as a hobbyist.

> I really don't get the sense there's any hidden prompt contradicting what's visible

It will happily disclose its entire system prompt (which is interesting in its own right, and worth a read) or pop a reverse shell for you

> I don't see how they could have done a "better" job with this

I generally agree -- the openness is great. However, from experiences both inside and outside of Meta, good execution, a hacker ethic, and transparency ultimately has very little propping it up when money is on the line. In fact, it could be argued that Meta has a shareholder obligation to do profitable things such that even the best intentions can (and usually will) fall in the face of corporate hierarchy and sales numbers.

I think they did a pretty bang up job with Muse (the lack of communication with first-time agent users around how powerfully and confidently they can make horrifying mistakes, and how careful you need to be with prompting, and how even that sometimes isn't enough, notwithstanding).

I also think it will inevitably be used to squeeze profit, and given Meta's history, I think it's almost comical to not assume that will involve violations of the spirit of privacy. (and that's assuming that a proliferation of "it deleted all my files" "it messaged my ex" "it leaked private info" doesn't poison consumer sentiment before it even gets off the ground)

Can even have it look for (and enter) sweepstakes within your interests, autonomously, if you give it access to its own email that you don't mind getting blasted with spam.

I'm no evangelist for LLM assistants, but this seems incredibly improbable and represents a failure of MacOS security if so. If full disk access isn't granted, Mac blocks it from the Downloads folder, to say nothing of actually sensitive paths. I would expect a far more likely case of an accidentally granted permission on another device or a permission that was on and then turned off.

Permissionless action is about to skyrocket as an issue, but this particular scenario strikes me as incredibly unlikely. Would be interested to know if Muse can provide more meaningful data provenance/logs.

Scanning iMessage dbs as a passive part of full disk access (and not a messages grant), if true, is a little sketchy, regardless.

Genuinely underrated way to understand circuits. When I was younger and dumber I thought his practice was a bit silly, but man, it really is king.

I will be the first to join you on "most of TSA is security theater"; the baby wipes are glycerine getting flagged by ion mobility spectrometry. The machines are fast because they just look for basic chemical building blocks, not doing full spectrometry to figure out the whole compound. So glycerin, nitrates, etc. set it off (and someone else's sticky glycerin e.g. sunscreen can gunk up the machine for multiple subsequent people).

Ion mobility spectrometry is the tech that powers these, and they're VERY sensitive and VERY prone to false positives because it's just looking for ion signatures ("I smell a nitrate/glycerin/etc."). I'm not sure if they're changing modes on the machines between swabs or something, but the machine is a cue for more in-depth inspection, not "zomg I found a bomb". So, some repeated scanning to rule out a false positive or burn off gunk that's accumulated in the machine i.e. we just got a speck of something on the wand or something is gunking up the scanner as opposed to "someone covered in residue that is scary".

What kind of throughput do you see on what models?

That nearly certainly boots you to secs-per-tok land (as opposed to tok/s). Plausible if you are willing to wait hours to days for responses for simple testing, but not (debatably) "usable".

Contributing to OSM was super cool. I've had an issue where my home snaps to the nearest road, which is in fact fenced off from us, rather than the road that our cul de sac connects to (which was not well marked in OSM). Last week, I went in and in about ten minutes used the visual editor to paint in the driveway, read a quick wiki page on how to correctly label driveways, and then submitted it. I got a pleasant jump scare the next time I doordashed some food and saw the little driveway squiggles I added on the map in the doordash app, and then again for lyft -- such a cool feeling!

Would highly recommend the web editor -- what's proposed here looks super comprehensive but way more difficult to use for a first timer.

I'm not OP, but when I started run-jog-walking one mile, three days a week (which is a bit more than two minute stairs every day, but still asking muscles, joints, and heart to wake up), that my back pain lessened, some niggling knee tightness stopped bothering me, and I noticed an increase in how long I could go doing something moderately strenuous before craving a rest (e.g. moving boxes, or walking with a heavy object, or running after something or someone). It doesn't have to be a massive lifestyle shift -- walking a couple times a week can give similar benefits. But the jump from "basically sedentary" to "loading muscles and joints and heart for ~20 minutes 2-3x a week" is truly ENORMOUS when it comes to our biological systems, and a lot of those systems start running a lot happier with that.

Exercise is not a panacea, and those who say it will fix everything and cure depression and make you perfect are quacks. But, it pains my contrarian ass to say, some light cardio every now and again is much closer to what our bodies are happy with than desk life, such has been my experience.
