From the littlei know from a breath holding workshop I did awhile ago (for trying to get into freediving) it's the carbon dioxide build up in our blood that gives us the urge to breath, and not the lack of oxygen. If this method allowed for the removal of carbon dioxide from the blood then holding your breath might not even be discomforting.
The acid base balance of the cerebrospinal fluid is the primary driver of the respiratory drive, like allude to with your comment on the CO2. I did want to add that the lack of oxygen can affect respiration, which is detected by the peripheral chemoreceptors, like in the carotid bodies.
Additionally, the thoracic stretch receptors are important for respiratory drive, where the lack of expansion of the chest will promote respiration. When a healthy young person holds their breath for short periods, say 30 seconds or so, their blood CO2 and O2 are not much different, but they still will have to fight the instinct to breathe!
I was kinda similar when I first started using it. I watched heaps of videos and had so many plugins installed but I was never really sure if I was doing it "right". Then one day I got annoyed and uninstalled every plugin and just went back to basics. I only reach for plugins when I feel something is missing, but honestly the only plugins I use are Style Settings which let's me customize the theme a bit more and Calendar so I can have... well... a calendar.
I think the real power of it is the fact you can extend as much, or as little as you want!
I know technology has come a long way, but it is amazing to me that they can fly two hunks of metal through space and align their positions down to a millimetre, while being a footy field and a half apart.
I wouldn't even know where to begin to tackle a problem like that.
Greg Egan's story "Riding the Crocodile" features a fancier version of this trick, fire three objects from three origins at close to maximum speed, precisely timed to arrive at a point despite the enormous relativistic delays, the objects incorporate powerful magnets, and are designed such that they don't actually collide per se if timing is correct - but as they pass each other at the point where they would collide if shaped differently the magnetic force slows them all and so they eventually stop, together, at this focal point.
The Amalgam in that story have fantastically better technology than we do, but this is certainly at the edge of what's practical for them. It's a fun idea though, I wonder how close we could get with our technology.
I love line scan cameras. Wikipedia has an awesome photo of a tram taken with a line scan camera on the relevant wiki page[1].
I've just moved to a house with a train line track out front. I want to see if I can use a normal camera to emulate a line scan camera. I have tried with a few random YouTube videos I found [2].
I think the biggest issue I face is that there simply isn't the frame rate in most camera's to get a nicely detailed line scan effect.
A normal frame rate is probably enough if you do it with groups of columns rather than a single column of pixels. That's what https://trains.jo-m.ch/ does with a Raspberry Pi camera, posted in https://news.ycombinator.com/item?id=35738987 with lots of questions and answers.
Oh wow that's neat! I honestly didn't think of using chunks instead of a single line and the result looks pretty good.
I love the fact the top (or first?) comment is by dllu, and looking on their webpage I saw the tram photo from Wikipedia! It's cool to see the photographer talking about their work. I think about that tram photo so much.
I remember years ago seeing a prerelease version of one of the wolverine movies. As the CGI models were still grayscale, it was cool to see at what points the fights were actors and what points it was CGI.
That was X-Men Origins: Wolverine. I was also thinking about that when I heard about this leak. This was the infamous Deadpool scene from it without the finished special effects, it's actually pretty interesting to see it this way.
Odysseus is the one of the few things to get me truly excited an quite some time. I will most likely never be able to attend one but by god I would love too.
I want to try get involved in the local event scene to get some experience. I think the only way I will get to experience something like Odysseus it is to run my own.
Man, there is no way I can read this. I got choked up just reading the titles of the blog posts, knowing what was coming.
I remember being younger and not being emotionally bothered by anything. Yet as I get older I am able to relate to so much more and everything hits so much harder because of it.
I made the mistake of reading it with my baby kid sleeping in the next room. I am not normally religious, but I'm probably going to say at least a few prayers before bed tonight.
I started reading from the beginning, and by the time I got to the post about her cancer recurring, and her parents having to tell her that she's going to die, I was sobbing.
Had to take a break. Not sure I can go back to it.
Edit: goodells explained it better!
