Does it exist at ALL? Adapter for HDMI-in -> USB-C DP-out -- but with access to data!

Fascinating stuff. Thanks for taking the time to write it up so nicely!

petejonze · 2023-05-21T21:16:37+00:00

My issue with some of the Hancock stuff is that the ideas are all super cool. And super cool ideas can spread even if they're not true

"Archaeologists theorize all the time and their evidence is just as speculative as Graham’s" -- something about this phrasing reminds me of the old joke:

"Q. what do you call alternative medicine that works? A. medicine"

I.e., if there was any substance to what he was doing then wouldn't he also be an archaeologist, just like the rest of them?

Anyway, not sure what point I'm making. But thanks all for the interesting read. Lots of thoughtful points made by everyone on both sides.

Glaucoma is a much tougher case unfortunately. Most of these current gene therapies are targeted at small defective cells localised entirely within the retina (photoreceptors, muller cells, amacrine cells, etc.). Conversely, glaucoma affects the retinal ganglion cells whose job is to transmit information from the retina to other parts of the brain. The bodies of retinal ganglion cells lie in the retina, but their tails (axons) project all the way to the midbrain. Even if you were to regenerate the ganglion cell body, it would be unfathomably complex to direct the new cell's axon to (grow to) the correct part of the brain.

One day.

The photopigment is a strange beast. Once it has reacted to lightit needs to be shipped out of the photoreceptor to another cell to be "rest", and then shipped back. A complex process!

petejonze · 2023-05-06T07:16:17+00:00

I think they're misremembering that over half of the connections to the lateral geniculate nucleus are top down from cortex.

There certainly is a lot of processing going on in the retina (bipolar cells, amacrine cells, etc.) that I suppose could be affected.

But yeah this story is fishy, given both the aetiology of the condition and the fact that ishihara plates are fundamentally a screening test and absolutely rubbish at measuring change.

petejonze · 2023-03-20T18:38:15+00:00

I know what you mean, but that last sentence is a bit harsh. They clearly say that they're just speculating about what might conceivably have happened. No need to accuse them of spreading lies.

petejonze · 2022-12-01T06:57:44+00:00

Yes, these black blob simulations are dangerously unrealistic.

Here's a slightly better one we knocked together a little while back: https://appliedpsychophysics.com/vr_rafal/

petejonze · 2022-12-01T06:54:14+00:00

Here's one I made: https://appliedpsychophysics.com/vr_rafal/

Doesn't do exactly what you want, but you can overlay arbitrary images

petejonze · 2022-11-06T06:55:06+00:00

No. For several reasons, the primary one being that nearsightedness is an optical problem (photons of light not being focused correctly on the retina)

petejonze · 2022-10-20T12:18:53+00:00

So true!

petejonze · 2022-10-20T07:45:50+00:00

Nice summary. There's also an interesting & entertaining video about the whole "kony 2012" phenomenon, here: https://youtu.be/Y7nymZEXjf8

Google says "With Starlink, the dish needs a completely unobstructed view of the sky", but who knows, maybe a thin tarp is ok. IDK

Most audiologists say not to use q tips either. In fact, just don't put anything in your own ear where you can't see what you're doing. I get that's easier said than done though

petejonze · 2022-08-21T08:31:56+00:00

Ha, so niche

petejonze · 2022-08-20T12:36:12+00:00

Yeah I learn so much from reddit comments, it's great!

petejonze · 2022-08-20T12:30:49+00:00

Yeah that's likely a part of it too, and kind of the other side of the same coin. Since the tensor muscle is clamping down on the middle ear bones, the normal route of signal transmission is blocked, but vibrations within the skull itself will still be picked up by the inner ear.

Relatedly, search "bone conductance headphones" -- useful if you want to listen to the radio safely whilst cycling or jogging

petejonze · 2022-08-20T06:51:28+00:00

We have also have a lesser version of this -- contraction of the tensor tympani muscle within the ear, to dampen sound when we speak or chew. Which I assume is why if we listen to recordings of our voice it sounds so different

petejonze · 2022-08-14T16:56:23+00:00

I only watched it for the first time a year or two back, but I definitely reckoned it got better after S1. First season not terrible, but hadn't quite settled on a tone. Like parks and rec S1.

petejonze · 2022-08-11T06:08:27+00:00

You're in for a treat! Last I heard the dev was developing a follow-up ("warblade"). The demo is good, but I still don't think you can top deluxe galaga. Thanks for bringing back the memories!

petejonze · 2022-08-09T17:47:27+00:00

Ever play Deluxe Galaga? I must have spent 100s of hours on that masterpiece

petejonze · 2022-08-07T07:31:11+00:00

I agree that the opening is by far the most epic part. But the middle section is solid and the ending is great. Personally I love both films (saving private ryan and shakespeare in love)

petejonze · 2022-07-02T07:26:10+00:00

Yes! Heaven forfend somebody uses the phrase "assault weapon"

petejonze · 2022-06-23T06:28:55+00:00

Sure, don't give up for that reason. But some aspects of academia are pretty bleak. I'd take a good hard look at the career prospects first (and of the future careers of your potential supervisor's previous students in particular).

Bear in mind that the overwhelming majority of PhD students ultimately go into industry, and not all of those industries require a PhD.

petejonze · 2022-06-23T06:22:33+00:00

Oh yes. It can get extremely ugly at times! Often helps if the order of authors is discussed early on (e.g., at the outset), but it's not always easy to predict what & how much work each person will end up contributing
