Open Source Systems Software Adventures

I have been looking at how Linux does The Internet. Some people think of Open Source as an ecosystem, but to me it's a bit more like studying geology than ecology. See Laura Hiking in The Grand Canyon in The Snow. The processes at work are things like deposition, uplift and erosion on a background of plate tectonics processes which occur on a much longer timescale. I even found something akin to Powell's Great Unconformity. See Rusty's Remarkably Unreliable Guides and Farewell from Rusty Russell (kernel.org). Early on, the uplift processes resulted in iproute2 and the basis for networking knowledge was washed away and replaced by Netfilter. But other uplift processes have been at work and there has been some igneous intrusion in the kernel in the form of the Berkeley Packet Filter. I wonder if this latent volcanism will ever come to anything? Meanwhile, aided by Gnomes --- some sort of petrified dwarves, I think --- deposition processes have been going on: we now have virtual machines and containers and snapcraft so we have something called netplan which sits on top of the freedesktop project's Network Manager. I wonder if they're feeling any heat yet? Now, can someone at Canonical please tell me how to find the information I need to set up my Ubuntu 24.04 desktop as a Proxy firewall/NAT gateway through my home router? That's not such a big deal, is it? I did it using OpenBSD in half an hour or so, but I am now three weeks into researching the same process on Ubuntu 24.04 and all I have so far is manually configured static routes to the local network.

A derivative is linearisation, and differential calculus is essentially linear algebra, ...  See  Freya Holmér - Why Can't You Multiply Vectors?  and  Freya Holmér on Continuity of Splines .

Alan Edelman talking about expressing mathematics as computer code. The idea is that you can use computer languages to communicate mathematical ideas precisely to other people.

... and his posterity too? See  On Communication in Linear Time And Hypertext And The Gospel of Sophia . So it looks like El Cielo of the cistine [sic!😂] chapel is not the limit anymore.  I think I just met one of his descendents. A guy called Versailles Toledo who is from Chiapas. That might explain the murals I mention in my recent untitled post , just before the post mentioning this video. I also just took this photo of Rafael Gonzales, born here in Tecate, B.C., who told me about a spring near here called Agua Fría , half way from Tecate to Loma Tova , where, a few decades ago, people used to go to have barbecues and stuff, but now he thinks it may be private land. If someone reading this has a Facebook account, please write a link to this post onto his FB page. To see why I took the photo, look at his T-shirt and the horse-shoes and ponder this: Subscribe to BeatrizER and her video(s?) about mathematical logic, ...
