The natural light and diffuse light are good tips.
Next is to get a big screen eg. 85" 4K and put it 1.5m away. That should be your main display. I don't have that all the time, but then I get some variety, 85" @ 1.5m a lot of the time, laptop some of the time, driving/walking etc. for longer range.
1.5m is the midpoint of focus for the muscles in your eyes.
I built augmented reality displays and this was the focal plane we selected for to minimize eye strain and the felt sense of vergence/accommodation conflict.
We could then throw graphics as close as ~30cm, or at infinity using vergence adjustments, even though the accommodation was at a fixed 1.5m. Graphics felt best at that distance, but they also felt ok in the range 0.5-10m, which suited nearly all productivity scenarios.
> do you not get sore having to dart your eyes about to read the corners?
I wouldn't be surprised if this is what makes it healthier. Not only are you exercising your eyes, you're also giving them a chance to let you know when they need a break.
I do almost exactly this, but instead use a cheapish 65" 4k/60hz TV instead. I can see bits of my surroundings with my peripheral vision, but only with the parts of my vision that are already blurry.
I suspect that 85" was chosen to maximize immersion for gamers (cover the entire field of view), rather than to minimize eyestrain. For me doing development work on a 65" from about 1.5m is close to ideal.
I have a 4k projector setup which I use from time to time instead of my regular 27” monitor. It makes a pretty big difference especially as it is reflected light. I can sit in front of it for hours without any noticeable eye strain.
It’s fine for doing graphical work or web browsing but really not ideal for things like code or excel as I lose my place too often with my eyes having to dart around further. Might just be sitting too close though.
Tell your optometrist you want that, and they'll write the prescription.
Last I went, they wrote me two different prescriptions: one with an up-close focal point for books/screen work, and a second one with the focal point further out for driving.
Yes. You can have reading lenses or lenses for medium distance. Measure the distance from your seat to the screen. Get a max, minimum and most common distance in your different seating positions.
The magic words I think are “occupational multifocals”, which have a small area at the top for distance vision and the remaining 75% set for whatever your occupation is. You need to be very specific on the distance setting
Some expensive lenses like Zeiss, Varilux, and Hoya make you an extra pair when you by one. I tought that the extra pair must be equal the first one, but it isn't necessary. I could have asked for a general one and one with a greater area for medium distance.
I would disagree with 1.5m, but I do recommend checking how close you are to your monitor.
Let's assume you have a reasonably sized office monitor (27" or so). Extend your arm with your hand as a fist, forward. If your screen is closer to you than your knuckles, it's too close.
Now, for the height: all monitor stands are too low. If you keep your head straight and look at the monitor, you should be looking at the upper third. VESA mounting arms or monitor stands solve this problem.
GP said too low, not too high. I'm thinking a typo though because that doesn't make much sense to me and I agree with you - I always have to adjust monitors as low as they can go in the office.
Not a typo. Most monitors are too low. You should not have to bend your neck to look at your monitor.
But some office setups have other issues, such as chairs that are too low, or desks that are too high, in which case your monitor might end up at the right height, but that doesn't mean much if the rest of your setup is wrong.
Begin with the desk+chair: they need to be set up so that when your hands are on the keyboard, your elbows form a right angle, or very close to it. Look at piano players for reference. Most setups fail that test. But once you get that right, you will notice that your monitor is way too low and all the stands are too low, which was my point.
You need to be looking at the top third when staring straight ahead, otherwise you will need to bend your neck to look at the lower part of the monitor and you will end up with neck pain. Top third, ideally around 2/3 of the monitor, so not the very top.
marginally relevant. space based dawn dusk LEO solar infra is the answer. vastly more power than we'll ever get on the surface of this rock and then onto Sol.
This is an awesome guide, but with mix dialyzer taking that long I'm curious: are you caching your PLTs? And if so, why not?
I've worked on some pretty huge Elixir apps, and I've seen the dialyzer take that long on the first run, but once the PLTs are cached it usually takes only a minute or two even in GH Actions
how much analysis have you done on this? I'm working on a series around Kardashev II work - space solar, asteroid mining, dyson spheres and the real work that is happening to support this now. contact me if you'd like to discuss - @bensand on X
Having built similar tech (Meta, YC S13), it's been a great year with Vision Pro, Orion, Spectacles and more coming out.
Currently at my co, seeing most day to day use out of XReal, and keen for Visor.
AR/XR/MR/VR app I'm most looking forward to is a 360 location share with the sharing user in AR, and the receiving user in VR, with additional virtual objects shared between. Orion would be great for the send side, with a few extra cameras and Vision Pro on the receive side.
The main thing letting down tech today is how open the platforms are for external developers.
The lack of projecting black I don't see as an issue, clip on something for VR (ok 70 degress isn't quite enough but getting fairly close), or just dim and use gradients for day to day work.
I think we're still at the most basic level in terms of understanding optical physics and ultra high resolution much smaller devices will come out, probably not too soon though.
I remember Meta (your old Meta not the new Zuck's Meta) had an amazing section of the site where you could submit and see sort of like Kickstarter proposals for use cases and I always wondered where all that creative devkit type passion went. Probably on a couple hard drives in a lockup.
Ah yes! I remember working on this. It was born out of asking all the YC founders what they wanted to see - and anyone else we met as well. Formed the basis of our second kickstarter which we self hosted and was much more successful.
> The main thing letting down tech today is how open the platforms are for external developers.
You mean how closed they are? Apple was bad about this, but I think Meta is pretty good with helping spatial / game devs? Am I wrong about that? I don't work in the space, it's just my impression
Yes, correct. As in their degree of openness (not much) is what's letting them down. I see how you could have read it as I meant their too open, which I definitely don't think is the case!
Hard edged, per-pixel light blocking is impossible for the foreseeable future. What's possible today, and what Magic Leap has, is diffuse dimming of large areas of the display.
The problem with light blocking is that when the blocker is millimeters from your eye it is completely out of focus. Unlike for the display, you can't use optics to make it appear farther away and in focus because the direction of the light it needs to attenuate can't be modified (or else your view of the world through the glasses would be warped).
For a near-eye light blocker to work, it would need to be a true holographic element which can selectively block incoming light based not just on its position but also its direction. Each pixel would essentially be an independent display unto itself that selectively blocks or passes incoming light based on its direction, instead of indiscriminately like a normal LCD. I have no idea how such a thing could ever be fabricated.
Damn! That's a throwback. I remember reading about you guys in an airplane magazine once and getting hooked on the concept. I always wondered where y'all went...
a bunch at Vision Pro, some at Zuck's Meta, some at Hololens, some doing other things. Meron is doing BCI, I'm doing AI infra - strongcompute.com (YC W22)
This strategy makes sense when the odds of winning are known, and the jackpot is not shared.
The powerball jackpot is shared so you would need to factor in the likely number of people you would share with which would be complicated to figure out.
There are cases in gambling where the jackpot is not shared, for example poker machines.
The odds of winning remain fixed, yet the jackpot slowly increases, moreso when there are many machines linked to build the same prize.
At a certain level of jackpot the math works out and it's a sound strategy to pour money into the machines.
If you were going to invest in lotto with shared jackpots I've heard anecdotes that choosing numbers 32 and higher is a better way to go because people tend to pick birthdays. I think looking at past drawing results and whether there was a winner or not you could analyse if numbers are picked disproprotionately, but I'm not sure what sample size would be needed to generate meaningful results.
All that said, I can think of many things I'd rather develop expertise in than reverse engineering the payout odds of poker / progressive jackpot machines.
Only if you're arriving from outside of Schengen. Within Schengen, there are only ID checks if the airline themselves have them there to avoid ticket resales.
I was planning to get most of these printed on a board of some kind, so they be more durable than posters, although I haven't chosen a supplier yet.
Depending on your use of the poster and the printer you go with you may need a rights release from the artist, so often it's easier to find a commercial print and get it framed, if you are willing to have all that glass.
Next is to get a big screen eg. 85" 4K and put it 1.5m away. That should be your main display. I don't have that all the time, but then I get some variety, 85" @ 1.5m a lot of the time, laptop some of the time, driving/walking etc. for longer range.
