> Wow, I guess China and the CCP really are great after all. Way better than the USA.

How does the parent imply China and the CCP are better than the US?


Yeah, neither goes twice into seven.


This is the best TLA+ specification of the Paxos algorithm I can find, for anyone interested. I was surprised that although Leslie Lamport has published a TLA+ spec for Paxos consensus¹, he has not published one for his Paxos algorithm itself, aka multi-Paxos. These Stony Brook academics did, complete with improved TLAPS machine proof and the added feature of preemption. Their digressions to existing Paxos proofs with other tools and the history of this algorithm's formal specification are also interesting.

¹ Paxos consensus refines specs for consensus and voting. See the spec and accompanying material here: https://lamport.azurewebsites.net/tla/paxos-algorithm.html


I think back to this essay every year and have done so for years. Worth re-reading. I learned the King James Ecclesiastes verse because of it.


"Time and chance happeneth to them all" is a phrase you read once and it is with you forever.


As Powell's chief of staff Col. Lawrence Wilkerson once recalled, that speech resulted in a resumption of hostilities for a war that already received Security Council approval back in the '90s - the original war never stopped, as no truce was ever agreed to, only detente. North and South Korea are in a similar state of detente. Powell's speech itself was an effort to receive political support for reengagement.


In case anyone missed the IEEE Spectrum piece "Here's How We Could Brighten Clouds to Cool the Earth" published Sept 7:

I want to test engines on the back of containerships to loft saltwater. That's the kind of R&D that is needed.

Or develop a shipping fuel additive that accelerates the production of clouds.

These won't solve the problem, but they can buy time. We need time.


Linux is "just" the kernel, and statements like

XNU UI > Linux UI > Windows NT UI

don't make sense because Linux has many different UIs. I'm pretty sure there is no macOS UI comparable to my preferred tiling window managers Sway and i3, and in that sense which UI is better is a question of personal preference and habit. In fact, I'm pretty sure only one macOS UI is available. Same for Windows: only one Windows UI available per Windows version.


Most people think of Linux as GNU/Linux. But of course you are technically right.


Just FYI for anyone having this issue, Tor 2.0 is deprecated and has been hit or miss for roughly the past year. As long as you're using their Tor 3.0 onion address you should have few issues.


From "Skynet Basics"[0],

> Behind the scenes, a Skynet portal is a Sia renter that rents and stores data for its users and can retrieve files from storage being rented by other portals.

I think you're describing one such portal.

"We refuse to" might be clearest of all.
