> apparently it's code named "red knot" (or "red_knot")

Missed opportunity to call it typy in my opinion


Previously discussed in 2017: https://news.ycombinator.com/item?id=15647452


Just listened to a segment about him on NPR, apparently his writing themes were greatly influenced by an experience he had as a child where he was standing next to someone who was killed by a lightning strike.


Which happens in one of his novels


> fixed-cost universal construction (it only takes fifteen gliders to build anything buildable)

Here’s the Hacker News discussion from when this was discovered: https://news.ycombinator.com/item?id=33797799

Dave, I’m still regularly blown away by this discovery. I don’t know what else there is to be said, but do you have any other comments regarding this?


Definitely I have lots more to say about 15-glider universal construction! It was a really exceptionally interesting collaboration, where several people working together were able to complete something that would have taken any one person a ridiculously long time to sort out.

Development of the RCT has slowed down a bit, though there's a hyper-optimized version in the works that will build a spacefiller instead of a Hensel decimal counter as its example pattern:

There's also another long-awaited project in the works, that will use quite a bit of the same technology along with some new ideas -- a unidimensional (one cell thick) spaceship:

https://conwaylife.com/forums/viewtopic.php?f=2&t=2040

It's improbably complex and awkward, of course, just like an RCT pattern, and it's huge though nowhere near as huge as an RCT pattern -- but there will be one phase of the spaceship that fits in a 1xN bounding box.


Is this the Jolly Roger restored build or a build of X-treme I haven’t heard of yet?


It's been several years I guess but from following my own breadcrumbs, yeah I think it was the Jollyroger build.


Darn. Thanks for checking though, I appreciate the effort


Something tells me it's someone's homebrew dev of Sonic x-treme. If it's that then the same developer also has a killer Quake style engine for the Saturn which is quite a showcase.


A similar website, but using genre clustering instead of artists: https://everynoise.com/


much, much better results and a wealth of additional features like several playlists for each genre, new releases, etc.


This is the best one. Such a cool site.


Demo of it in action, crazy stuff: https://youtu.be/F8jlJapQbFY


If you can find the source for that I’d love to read about it

From the NOVA episode which gets to the human related part, (but that whyy article is on the protomammal rather than primate and thus may be of more interest to you).

> All was going as planned until McCoy’s bioinformatics specialist Steve Howes rushed into his lab in 1997 to show him the sequence of a gene they called syncytin, which their work showed was secreted by placenta tissue.

> Before McCoy could go public with his discovery, he needed to figure out exactly what syncytin did, a job he passed to bench scientist Sha Mi, who everyone called Misha. Misha’s experiments seemed to be going as planned until, a few months later, she, too, rushed into McCoy’s lab with findings of her own.

> Syncytin is produced only by certain cells in the placenta, and it directs the formation of the cellular boundary between the placenta and maternal tissue. Approximately one week after fertilization, the egg, now a hollow ball of cells called a blastocyst, implants itself into the uterus, stimulating the formation of the placenta, which provides the fetus with oxygen and nutrients while removing carbon dioxide and other wastes. It also serves as a barrier to prevent infection and keep maternal and fetal blood separate. (Mixing the two could cause a fatal autoimmune response.) The cells in the outer layer of the blastocyst form the outer layer of the placenta, and those in direct contact with the uterus are the only ones that made syncytin.

I read this theory in The Mom Gene but I'm not sure where it sourced from.


You might notice that your project is already included in the Readme under credits.


I did not notice. Neat. I appreciate the PS1 more. Remembering way back, N64 carts were 10 dollars or so more than PS1 discs, and as a result I had a stockpile of PS1 games. The texture popping of the PS1 I could never make sense of but it became an aesthetic of the era. Nice work OP, and thankyou for the credit


I know there’s another reply with videos here. I’m gonna put an explanation in text.

The N64 had two things which made things smoother. It had sub-pixel precision for geometry after projection, and it had perspective-correct interpolation. This meant that moving objects looked smooth and didn’t “pop”. Games on the PS1 addressed the interpolation problem by subdividing, but you could sometimes see geometry suddenly move when you got closer and saw more subdivisions.

The N64 also had texture interpolation (kind of like bilinear) and antialiasing, but those don’t make as big an impact.

The N64 got all these things right, more or less, but had problems with memory bandwidth and small texture memory.


I was also under the impression the PS1 only had integer precision? Would that contribute to the wobbling and popping?


That’s the “subpixel” precision I’m talking about.

Because the rest of the commentors in this thread seem to not be reading the article, there's a performance issue in Firefox due to the following unresolved bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1190398


5 years old and not a peep. That sounds about right.


5 years? That's nice. https://bugzilla.mozilla.org/show_bug.cgi?id=70315 took 18 years to get solved.


I wonder what exactly is Firefox dev team spending all that time saved by not fixing peformance issues such as the bug linked above.

Chrome seems to be doing some things right and Firefox is just adrift...


The link to the demo comes before the warning to firefox, don't shame commenters who chose to see the content at discussion first before reading below the fold.


Who's shaming anyone?


Guess . . . . "Because the rest of the commentors in this thread seem to not be reading the article"


We'll, they're not reading the article, yet they're expecting people to read their comment. And if not, why comment at all?

I think some selective derision is warranted.


While it says that "[...] you need to use a Chromium or Webkit browser to enjoy MONOSPACE live." (emphasis mine), it does not say "DO NOT USE FIREFOX UNDER ANY CIRCUMSTANCES, it will mess up your device for minutes" anywhere.

We saw so many (warranted or unwarranted) "Best viewed with Chrome"-statements on the web already that we became desensitized to it years ago.


No, please don't add derision to HN threads. When someone else is wrong, it's enough to supply correct information. That enhances the thread without damaging the commons.

Are you saying everything everyone says is above critique, or that derision specifically is not welcome?


The latter. It's never needed and does more harm than good.


Ok. Thanks for answering.
