(in reply to end of DATA command)Very neat, and impressive. The one downside I noticed for the exemplar page is the browser CPU load. constant 33% of 1 CPU on an AMD Ryzen 7 1800X with Firefox v103.0.2, and around 32% with Chromium v104.0.5112.79.
I guess that's fair though since the 'page' is playing Towers of Hanoi AND animating the Hilbert curve AND a linear watch (clock)!
I enjoy the presentation itself too - no wasted space, nice multi column, no space-wasting top-bar, no annoying sidebars.
Being able to invoke the code editor with the floating resizeable text-area feels so natural.
The one thing that would be good seeing as the page is a viewport onto a larger canvas is auto-scrolling the viewport when the pointer approaches the margins - so we don't have to chase, make visible, and manually grab the browser scroll bars. That would make the page naturally follow where our attention currently is.
Certainly brings a whole new meaning to "Single Page Application".
Not even going to attempt to view it on a small device though!
The only downside is requiring client-side Javascript to render - I wonder if there's a way to have a fallback to render server-side in that case?
I've been procrastinating over choice of some kind of simple wiki-like static site generator for recording many real-time stream-of-consciousness disparate unrelated bug investigations,fixes and code hacking across a wide range of open-source software.
This has a quirkiness to it that I like and it feels like a nice fit for someone with a coding ethos (even if not usually into functional!).
It may even conquer my preference for Markdown!
Time to explore!
Since buyer's time is valuable, and wasted negotiating time frustrating, having a friction-free non-delayed experience would surely be a valuable data-point to many -- as in "I don't want to use a dealer whose average time-to-final-price is more than 30 minutes."
Can't do that in voice chat.
In the usual case of IRC channels the contributors are in the minority and so it can take the form of a voyeuristic learning experience for the passive bystanders - and very highly educational most of the time.
If I'm not present when friends are chatting I don't get to replay what they were saying before I arrived, or after I leave.
I think that is the fundamental disjoint - features are attributed to IRC that were not intended, and then attempts to bolt them on through services, bouncers, or whatever, is never going to create a seamless rich experience that many seem to want.
For me, IRC has always been the avenue for mostly throwaway, real-time at-this-moment off-the-top-of-my-head stream-of-consciousness discussion, with Usenet or forums and email mailing lists for more long-running considered and logged discussions.
I've never been impressed or attracted to products that try to force the two styles together.

In your scenario, 10:1 contention ratio, "up-to" 1Gbps throughput, 1Gbps link-speed.
In the UK British Telecom originally offered 'consumer' ADSL at 50:1 and 'business' (more expensive) at 20:1 contention ratio specifically to deal with the backhaul limitations.
As of now we have over 12K Starlinks in Ukraine. They help with access to high-quality internet in difficult conditions. Still we are wondering of all possible ways to use @SpaceX tech. Our telecom team made Starlink test drive on the road at a speed of 130 km/h. Check the video.
Unfortunately (for me at least), the recently re-recorded collection (by the Pratchett estate) using different voice artists (Indira Varma, Peter Serafinowicz, Bill Nighy, Steven Cree) don't capture the same 'magic' as the original voices and often fail to recognise and pronounce the subtle double and triple entendres (e.g. of the Nac Mac Feegles) - which suggests they and the editors don't fully appreciate the humour Pratchett intended.
Don't miss the "The Science of Discworld" series (book I (1999), II:The Globe (2002), III:Darwin's Watch (2005), IV:Judgement Day (2013)) where the chapters alternate between stories of the Wizzards (voiced by Stephen Cohen) of Unseen University accidentally creating Roundworld (Earth and our universe) and then tinkering with its evolutionary timeline in a battle with the Elves, eventually leading to humans leaving the planet using a Space elevator, and serious explanation and exposition of the sciences by Jack Cohen and Professor Ian Stewart (voiced by Michael Fenton-Stevens).
Those make a great introduction to science for kids young and old!
"The Folklore of Discworld" and some of the loosely related stories such as Mrs Bradshaw's Handbook (voiced by Penelope Keith - a skit on the Victorian era "Bradshaw's" railway travel guide [2] and a spin-off from "Raising Steam", featuring her travels on the Ankh-Morpork and Sto Plains Hygienic Railway), "The World of Poo" (Sam Vimes son's fascination with collecting poo specimens) and, unrelated to Discworld but written in the same tongue-in-cheek style "Dodger", a tale set in Victorian London featuring a lovable Tosher discovered by 'Charlie' (Charles Dickens).

user.max_user_namespaces = 127864Fix is introduced in commit 7e6bc1f6cabcd30aba0b11219d8e01b952eacbb6. On the wider point of kernel corruption it isn't absolutely clear if the PoC relies on specific attributes of the target kernel builds or a suitable .config, and if so which, or very specific kernel versions between v4.1-rc1 and v5.19-rc7.
Article talks specifically about "Ubuntu 22.04" and shows kernel 5.15.0-27-generic in the poc.gif but the github README.md says 5.15.0-39-generic. No mention if this affects the -lowlatency kernels.
Recent Linux stable tree kernels carry the patch (e.g. v5.18.12 commit 6b7488071ea8ed6265a39afebd5a5920f6975d02).
The exploit fails (here) on stable tree v5.18.9 in an interesting way!
$ ./poc
[+] Second process currently waiting
[+] Get CAP_NET_ADMIN capability
[+] Netlink socket created
[+] Netlink socket bound
[+] Table table created
[+] Set for the leak created
[+] Set for write primitive created
[*] Leak in process[-] add_key: Disk quota exceeded
The message via perror() is of course wrong; in fact during the call via SYSCALL_DEFINES(add_key, ...) in security/keys/keyctl.c a return value of 122 (EDQUOT) is returned. There are 3 call sites in that function that call PTR_ERR() - a function that determines if a pointer value is a valid 'errno' value - so one of strndup_user(), lookup_user_key(), or key_create_or_update() failed.

As others have said, originally Fedorov Mykhailo, a Ukraine vice prime minister, publicly tweeted a request for Starlink service and terminals [0] and later thanked SpaceX after they arrived in-country [1] and today, in Ukraine media, the mayor of Kyiv is pictured with terminals about to be deployed [2]:
"“Friends! StarLink global satellite Internet stations are already in Kyiv. Two stations were provided by the Ministry of Digital Transformation. I and Volodymyr [Klitschko] agreed on provision of ten stations with international partners and friends," Kyiv Mayor Vitaliy Klitschko posted on Telegram.
According to him, StarLink will help ensure the critical infrastructure of the city and the defense of the capital."

Much fun was had programming in machine language by looking up op-codes in Rodney Zak's "Programming the Z80" and counting the clock cycles to figure out the most efficient set of op-codes. As I recall the fastest op-code requires 4 clock cycles but some instructions would need more than 10 so much performance could be gained by knowing and optimising. This was before there was a Z80 assembler available so the hex of those op-codes had to be typed and POKEd into memory from the BASIC interpreter.
A side-note - don't forget the ZX81 was preceded by the Sinclair ZX80 in 1980 [0].
Most accessory sockets are rated 10 or 15 amps.

Once you analyse what is required to be truly self-sufficient and self-reliant, even for short periods of time, the amount of equipment needed is quite surprising.
In settled life many of those things are externalised costs or can be obtained on-demand.
I'd still love to give it a go at some point - but would need to move to Alaska to do it (Only rain and mud in the UK!)
Traditional nomadic life was about entire communities or extended families (rather than individuals), usually carrying their entire home and possessions with them either on travois or animals and/or carts, and travelling between home sites as the seasons changed or the food source moved.
In current times it's not too challenging to carry one's entire digital possessions in a back-pack if you trust to there being an always-on quality network connection, but it'd be far more comfortable to kit out a mobile home, caravan, recreational vehicle, boat, or similar, if you want basics with you such as favourite clothing, personal items, and physical documents.
A challenge of this minimalisation is overcoming built-in obsolescence of most digital devices that often leads to collections of older 'stuff' kept 'just in case', as well as connectors, adapters, wires, and other bits. Oh, and avoiding buying 'convenience' single-purpose devices.
Having Siberian Huskies I once tried to figure out if I could live off the back of a sled and have the huskies be my means of transport. The sled would have needed to be 5 meters long and about 2 tall so I abandoned the idea!
