The Computation — Claude Shannon and the Art of Choosing a Problem
"The point I want to make is that there is no problem unworthy of a solution. Note that while pursuing such toy interests, Shannon wasn’t a nobody dwelling in his garage from day to night. He was one of the most well-known mathematicians of his time, even before his information theory breakthrough at age 32. It would be a no-brainer for him to decide to focus on more “important” problems instead of juggling for example."

"If you are interested in something, then there is nothing keeping you from exploring it deeper. Leave aside your truly mandatory responsibilities, and everything else is optional. There is no problem you shouldn’t try to solve."

Welcome to DiscDAG ...
" In email, for example, top-posting has won. So people quote the entire email and put their response at the top. So they say ... "I quite agree. With what? What do they agree with? There were seven different points in this email ... do you agree with all of them? If not, then which ones? "

"You have nodes with comments, and people can reply to individual nodes, or entire threads, or even multiple threads all at once. "

Fast Light Toolkit - Fast Light Toolkit (FLTK)
lobsters: "And if Tcl/Tk isn’t good enough? You know, sometimes that higher standard of quality is required for consumers, and if it is, you’ll waste so much time trying to get that quality out of a “cross-platform GUI framework” that you might’ve just as well used a “native” framework and written your code twice, because your program will always be bigger than your competitors, and slower than them, and it’ll always feel a little bit off even if you do everything else right."

How SNES emulators got a few pixels from complete perfection | Ars Technica
"Today, we enjoy cycle-level accuracy for nearly every component of the SNES. The sole exception is the PPUs (picture processing units), which are used to generate the video frames sent to your screen. We mostly know how the PPUs work, but we have to make guesses for some functionality that result in less than total perfection."

"I want this final piece solved so that I can feel confident in my retirement that the SNES has been faithfully and completely preserved through emulation. No stone was left unturned, no area left unfinished. I want to say that it's done."

Seizo Watase’s Heart Cocktail – ZIMMERIT – Anime | Manga | Garage Kits | Doujinshi
"Modern “short” anime (that is, short episodes rather than short seasons) tends to skew towards absurd comedy to make the most of limited budgets, but what if those limitations were embraced and taken in the opposite direction? It might look a lot like Heart Cocktail[based on Seizo Watase’s manga]"

The 'S' in Zoom, Stands for Security | Objective-See
- 2009 0day for quietly creating a unsecured webserver on localhost
- Facebook Metrics API usage without telling people
- invoking the AuthorizationExecuteWithPrivileges API...but delegating to a (easily-replaceable) shell script
- Code injection for mic/camera access: the app is compiled on OSX with the 'Hardened Runtime' profile...but then uses the "Disable Library Validation Entitlement" flag, which almost completely defeats the purpose(allows ANY library to be loaded into the address space)

GitHub - musnix/musnix: Real-time audio in NixOS
a add-in or Nix Channel that "provides a set of simple, high-level configuration options for doing real-time audio work in NixOS, including optimizing the kernel, applying the CONFIG_PREEMPT_RT patch to it, and adjusting various low-level system settings."
Do note that using a RT Linux kernel can introduce other fun problems, so this is mainly if you need pro-level audio work. Also if you want to get JACK to work?

Bend it like gen_statem
"You see, the challenge is being able to breathe ‘gen_server’ as if one has gills, so that one can keep the maze of their state-machine straight in their head. It helps to first mock up your state-machine in a truth-table, give it some thought, sleep on it, re-work it, before jumping into the code. If you do that, then the task of crafting a state machine using ‘gen_statem’ isn’t too grueling."

It’s Amazing That Anyone Upgrades Their iPhone - 500ish
"I’ve owned every iPhone since the original one back in 2007. Each time that I get the latest version I do something many people consider crazy: I set it up as a new iPhone, rather than restoring a backup of my last device. My rationale is both simple and silly: I like the idea of this being a natural “reset” of my phone — a way to determine which apps I really want, or more to the point, need, on my device. It’s always far fewer than I think. And certainly less than I would have if I restored and deleted just the ones I thought I wouldn’t miss."
"Anyway, I bring this up because this process, while in a way liberating, is also a pain. It takes a long time to re-download every app that I actually want. And, of course, even longer to log in to each of these apps. One by one.
And yet I was reminded this week that my process actually isn’t that much more laborious than the more traditional restore. A few weeks back I bought my wife the latest iPhone — she had been using an iPhone 8, and I wanted her to have the best camera to take pictures of our little girl¹ — but she kept pushing off setting it up. When I asked her why, she noted that the restore process is incredibly slow and cumbersome."

Moé for Moai – ZIMMERIT – Anime | Manga | Garage Kits | Doujinshi
"Ultimately, it’s hard to pin down one reason why Japan is so moé for moai (okay, first you have to accept that premise itself, but man, I don’t see America erecting fake moai all over the country, putting them in video games and VHS logos or selling moai-shaped chocolates). "
"And despite an obvious difference in size, Easter Island and Japan are both islands, subject to the whims of earthquakes and tsunami. Whatever it is, there seems to be something in moai that appeals to Japanese... emotion."

Coronavirus is leading states to close their borders - Vox
"As Pritzker writes, “it’s the federal government’s job to make sure that a nurse being properly equipped in Illinois doesn’t come at the cost of a doctor being ready for work in California.”

If the Trump administration is unwilling or unable to uphold its end of the post-New Deal bargain, the implications are staggering. Trump’s inaction does not simply threaten to exacerbate a pandemic. It threatens the very concept of what it means to be the United States of America."

I had the opportunity to touch upon it when I was writing the Game Engine Black Book: DOOM two years ago but I wanted to go deeper. My curiosity was so great that I decided to relax my rules and use DOOM instead of Another World at a pretext to dig in. "

F-Zero GX/AX – 2003 Developer Interviews - shmuplations.com
"In these interviews, members of Nintendo and Sega’s Amusement Vision studio, including long-time F-Zero designer Takaya Imamura and Amusement Vision head honcho Toshihiro Nagoshi, discuss their collective vision for the 2003 Gamecube racing game F-Zero GX and its arcade counterpart, F-Zero AX.

Born from Nintendo’s “Triforce” initiative, which saw them team up with arcade veterans Namco and Sega to produce externally-developed arcade games using Nintendo IP with the eventual goal of securing much-needed third-party software for the Gamecube, these games represented both Nintendo’s long-awaited return to arcades and Sega’s first genuine collaboration with their long-time rival, with the end result being a pair of games that are considered by many to be the series’ apotheosis.

How are Unix pipes implemented?
"This important property, along with the POSIX requirement that writing up to PIPE_BUF (at least 512) bytes into a pipe must be atomic, allows processes to communicate with each other over a pipe in a way that regular files (which have no such guarantees) could not support. With a regular file, a process could write all its output and hand it over to the next process, or they could operate in lock-step by using an external signalling mechanism (like a semaphore) to let each other know when they were done reading or writing. Pipes eliminate all this complexity."

DOJ Wants to Suspend Constitutional Rights for Coronavirus Emergency - Rolling Stone

"While the asks from the Department of Justice will likely not come to fruition with a Democratically-controlled House of Representatives, they demonstrate how much this White House has a frightening disregard for rights enumerated in the Constitution."

(it's basically suspending habeas corpus, and suspending statute of limitations until a year after "the emergency is over")

Simplify: move code into database functions | Derek Sivers
"In 1997, I started in Perl. In 1998, I switched to PHP. In 2004, a rewrite in Rails. In 2007, back to PHP. In 2009, minimalist Ruby. In 2012, client-side JavaScript. Each time I’d have to re-write all of the logic around the database: how to add a new person into the database, how to verify an invoice is correct, how to mark an order as paid, etc. But that whole time, my trusty PostgreSQL database stayed the same. Since most of this is data logic, not business logic, it should be in the database. "

How Deeply Is COVID-19 Impacting Anime Production? - Anime News Network
"A number of anime studios have told their employees to work from home, which can have a varying impact depending on the studio, according to one producer I spoke to. Many freelance animators already work remotely, so there's not a ton of disruption there. Some CG studios, however, only provide employees access to expensive 3-D software on their office computers, so working from home requires setting up a VPN (virtual private network) to allow them to log into the computers remotely. This can cost them precious time while they transition to the new setup! "
"However, the real risk comes from ripple effects. The anime industry is a tight web of studios that hire each other for supplementary production work on each other's shows. A sick artist or a project getting pushed back can throw studios' careful schedules and budgets completely out of whack. Most studios also outsource work to the rest of the industry, meaning that issues with their contractors can delay delivery of in-betweens, backgrounds, or CG animation. "
