ZFS 的新功能,增加硬碟進已經存在的 RAIDZ 裡面
整理 Hacker News Daily 上看到的,可以直接把硬碟加到 ZFS 裡已經存在的 RAIDZ 群組裡面了:「ZFS 2.3 released with ZFS raidz expan
@solar_chase #nuclear isn't "clean", and everyone who claims so has never seen the any #Uranium mine, #refinery or has a Spent Fuel Storage Facility in their backyard.
Months pass too quickly
Two-thirds behind already
Better unmeasured

RAID6 的 Erasure code 實作
Daily Hacker News 上看到的紋章,「Erasure Coding for Distributed Systems」這篇討論了 Erasure code。
以前在學校裡面學 coding theory 的時候有學到一些經典的演算法,尤其是一定會教到 Reed-Solomon error correction 這個演算法,不過實務上 Reed-Solomon 因為用到 finite field 運算 (又稱 Galois field,所以簡寫常用 ),所以效率並不算好,在 RAID 系統上面除非 controller 的

Finite:
Life
in a physical body
Infinite:
Existence
in all its experience
I live
I exist
I experience

@g3om4c to me that's criminally "#WastefulComputing"...
Also wasting the very #finite nuclear fuel to boil water to make a turbine go brrr and churn out electricity is not only insulting to the universe in terms of wastefulness but also a bad application for said resources that could be used more efficiently in more pressing matters of #science and #technology.

Q: What are Eleventy’s states?
While trying to understand Eleventy better, I found myself wondering how I would draw a state diagram of Eleventy.
(Aside: Not a diagram I have a lot of experience creating, but I find looking at them useful!)
I know Eleventy is not _implemented_ as a finite state machine...but is it possible to _represent_ its states like one?

Crazy how much difference the right data structure / #algorithm for a task makes.
This week I learned about #Deterministic #Finite #Automata and #Nondeterministic Finite Automata just to redo my clunky #AdventOfCode2023 day 12 challenge, written in #Rust #RustLang
Runtime for part 1 dropped from 1-2secs to milliseconds. Part 2 also milliseconds
Are there any good Rust crates for DFAs/NFAs?
Many people solved that problem with #Dynamic #Programming - something else for the learn list
@TwraSun #Bildbeschreibung fehlt...
Ansonsten #FragWarum - vielleicht weil jene #embedded sind mit den #Energiekonzernen die #finite, #fossile #Energie [und ja auch #Atomkraft gehört dazu, nur weil's mineralisch ist wird's nicht weniger endlich!] produzieren und nutzen???
We are happy to announce that our Research in Teams visitors Naoyuki Kanomata and Akifumi Sako published a new paper on #Finite Φ3-Φ4 #HybridMatrix Model.
Look into it if your favourite field is #HighEnergyPhysics.

@codingquark Well, if you assume that the #universe is fundamentally #discrete and #deterministic, the implied result is either a repeating #finite system, or as I said in the following post, a non-repeating system that necessarily is experienced by versions of you that differ from current-you without bound. #cosmology #conjecture

@unicorn_bianca Yep, everyone was sinful, including the orangutans. And the sloths. And the carp. And the breakfast cereals...
But yeah, #FreeWill under threat of #infinite #punishment for #finite acts isn't #free, #just, #sensical, or #fair. Following that line of reasoning leads to the conclusion that #God created people specifically without truly free will for the purpose of being punished for eternity.
