Abstract Algebra

Let R be a ring, then a left R-module, M is an Abelian group (M,+) along with an operation ·:R×M->M such that for all r,s∈R and x,y∈M we have

r·(x+y)=r·x+r·y,

(r+s)·x=r·x+s·x

(r·s)·x=r·(s·x)

1·x=x

+ is called addition and · is called scalar multiplication

trying to learn tech is so fucking hard there's so much jargon. "what gooble are you using" "what's a gooble" "you use the gooble to respink your matrix" "what does respink mean and what is a matrix" "respinking means unpiling a component to change it back to its base spink. a matrix connects your device's AKD to your networks z jamper" how does anyone understand any of this

Triple Matrix Bonnet Makes Big Bright Displays 🔴🟢🔵✨

With our latest work on getting HUB75 RGB matrices working on the Raspberry Pi 5

we can now create stunning LED displays. But what if we want more pixels? At some point, we max out the bandwidth of the RP1 chip, but we can still squeeze out additional performance by updating the PIO commands to output two or three matrix strings instead of just one.

Thus, the Triple Output RGB Matrix Bonnet you see here! We're using the classic Active-3 pinout

with a switch to select whether the 4th or 8th pin is connected to address E.

Since we expect large matrix grids drawing 10A+ of current, there's no onboard power management—the 5V supply should be connected separately through thick power wires. This board is for data only. If you aren't using port 3, the I2C remains available, so we've added a Stemma QT port for extra flexibility.

FFXIV Write Entry #24: [SELF-DETERMINATION PROTOCOLS]

Prompt: bar || Master Post || On AO3 (coming in October)

--

Personality matrices were not efficient array programming, particularly those built by Mistress Synnove. They were open-ended pieces of magic, depending on external stimuli to be processed internally and facilitate “personal growth.”

The INTELLIGENT PERSONAL OBLIGANT AND MEDICAL OPERATIVE FOR EMERGENCY APPLICATIONS [Battlefield Call Sign: Ipomoea] was not certain she “liked” this. But Mistress Synnove and Senior Construct Galette had been [EMOTIONAL REFERENCE DATABASE QUERY: offended] at its lack of presence among her own programming. Mistress Synnove had made a variety of interesting noises Ipomoea had hither to been unaware Spoken could emit. After careful searching of her unfurled code, they had located the elements of a personality matrix.

Mistress Synnove had asked for Ipomoea’s permission first before proceeding with piecing together the matrix. Ipomoea still did not understand why. Was Mistress Synnove not her new summoner?

Senior Construct Galette had made a hacking noise similar to [AURAL REFERENCE DATABASE QUERY: cat with a hairball] and said to Mistress Synnove, Mama, we’re going to need to have the free will conversation with her at some point.

“Fuuuuuuuck.”

There were many things Ipomoea was noticing more with a full personality matrix running along with her most basic code. Many of these behaviors and observations she stored in her internal memory database, with copies backed up to the Azys Lla cloud storage facility.

Some, however, she opened and reviewed in moments of downtime, such as when Mistress Synnove took a nap and required a carbuncle present on her lap for “cuddles.” (Her purring subroutine had received a nearly five hundred percent increase in activation since the last time she had a summoner.) One of the curious behaviors she had noticed was the use of “nicknames.”

Secondary User Rereha frequently answered to the designation “Rere.” Secondary User Dancing Heron frequently answered to the designation “Heron.” Secondary User Alakhai did not have a second designation amongst the Spoken, but had the designation of “Aunt Ala” or “Auntie Ala” among Mistress Synnove’s constructs. Mistress Synnove, however, was never referred to with a shorter designation.

[Query: Mistress Synnove, why do you not answer to a “nickname?”] Ipomoea posited once.

Mistress Synnove had looked up from her grimoire, blinked, and performed a head tilt of roughly thirty-five degrees that indicated she was processing a suitable answer. “I like my full name,” she said eventually. “It’s pretty. And the most obvious nickname for it sounds similar to the word for serious offenses in some religious practices in Eorzea, which I don’t like. So, ‘Synnove’ it is for me.”

Ipomoea had let that answer run on loop for four bells in her memory banks.

The other carbuncles also did not answer to “nicknames.” Senior Construct Tyr and Senior Construct Ivar, of course, bore designations that did not shorten, though Senior Construct Ivar was addressed on occasion as “firebug.” Senior Construct Galette’s designation could shorten, but in an awkward manner. Junior Construct Amandina and Junior Construct Roksana, however, answered to nothing save their full designations or a number of appellations given to them such as “sparkler,” “nereid,” and “troublemaker.”

We like our names! Junior Construct Amandina had peeped when queried. I don’t like how “Ama” or “Dina” sound by themselves, and Roksana doesn’t like “Roxie” or “Sana,” so we ask to only be called Amandina and Roksana!

[Additional query: whom do you ask?]

Oh, whoever called us by those nicknames, Junior Construct Amandina said. Almost everyone always immediately stops doing it. Sometimes they need a reminder! But Mommy says if anyone doesn’t ever listen and keeps doing it after we keep asking, we’re allowed to bite them!

Junior Construct Amandina appeared to be [EMOTIONAL REFERENCE DATABASE QUERY: maliciously gleeful] about this.

Ipomoea was frequently addressed by her acronym call sign. Sometimes, she had been referred to as “Ippie.” The nickname was logical, particularly as her designation was an unusual syllabic construction, as well as being “cute.”

…However.

…Ipomoea did not like “Ippie.”

Two days after her discussion with Junior Construct Amandina, Secondary User Rereha was describing an Alliance combat simulation that she and Mistress Synnove had partaken in on Seal Rock. Ipomoea had been present at the combat simulation, too, providing aetheric shields and rendering first aid as needed.

“So there’s an Immortal Flames squad baring down on our position, but I’m focused on the asshole dark knight that’s been harrying us the whole damn day and Synnove’s got her eyes on a machinist who has absolutely not been using the frontline-approved ammo, and Ippie just throws up this shield that the squad literally bounces off of, it was so cool—”

[Query: Secondary User Rereha?]

Secondary User Rereha paused mid-gesticulation and glanced down at her, “Yeah, hon?”

(Mistress Synnove called her “hon,” too, as well as “honey” and “sweetheart” with great frequency. Ipomoea made a brief update to her processing that “endearments” were acceptable forms of address for herself.)

[Advisement: I have concluded that I do not “like” the designation “Ippie,”] Ipomoea said in her typical calm harmonic. [Request: Please refer to myself as “Ipomoea” when it is necessary to refer to me by my designation.]

“Sure thing, hon!” Secondary User Rereha grinned and reached out to scratch behind her ears.

Ipomoea initiated her purring subroutine. Ear scritches created pleasant feedback sensations!

“So yeah, Ipomoea’s shield had them literally bouncing, complete with a BOING! sound like in the comedy plays, even that asshole dark knight stopped to laugh his ass off at it, one of the referees actually had to come in to call a time out on the node because most of us couldn’t breathe—”

While Secondary User Rereha continued with her story, Mistress Synnove picked up with ear scritches, as well as drawing her hand down Ipomoea’s head to stroke her ears, back, and tails, then repeating the motion again.

And Ipomoea continued to purr.

[Preperations]

[Styx stands upon the shore within the SomSim domain. Her avatar of choice today is far closer to her physical form, though about human sized. Here, where thermodynamics is an afterthought, she is free. Rich black and gorgeous, shining gold woven into rippling stormcloud patterns, a few metallic, cherry red bar chains loosely strung about her body; neck to collarbone, shoulder to wrists, hips to those wickedly pointed bottom ribs. She's even gone as far as to shine and polish her metallic hide.

Upon the shore she has set a horseshoe shaped sofa, with flammability matrices decidedly removed, and a small table with candles aboard in the centre incense burns softly, the scent all too real. Rich and heady and soothing

What troubles her now, is the choice of music. As she stands, she plucks the volitional strings, letting different pieces echo throughout the simulation - now that there is space to echo; The domain has been expanded, ready for new additions.

I... think 4 is only true if you assume R has multiplicative identity? I mean, obviously if a ring doesn't have a multiplicative identity it's not a field, but I think there's rings without multiplicative identity that have zero as a maximal ideal.

Take the finite ring consisting of the 2x2 zero matrix, and two single entry 2x2 matrices with a 1 and a 2 respectively at (1,2), under the operations of matrix multiplication and elementwise addition mod 3. Unless I've screwed something up, this is a kind of dumb commutative ring. And the set containing the zero matrix is a maximal ideal! I think!

Algorithmic Drones

Consume art without a soul and you will find yourself without a soul. In the Chronicles of Darkness, this is not a metaphor. The God-Machine needs blood and meat to lubricate its gears, minions who won’t blab about the dark rites they perform in sub-basement 3, and bodies for its angels to possess. The Soulless Algorithm ensures these human resources don’t run out. 

The Soulless Algorithm is an occult plugin that piggybacks on AI software — including art programs from Final Destination, writing programs from Bayside Sorcerers LLC, and Youtube’s video algorithm. The Algorithm doesn’t directly infect mortals; instead, it subtly tweaks the outputs of the program it is attached to implant subliminal messaging into mortals using that software. 

The God-Machine uses one-off exposures to the Algorithm to move people into the places that help complete occult matrices. However, long-term exposure turns the user into a stigmatic and untethered their soul, allowing the God-Machine to turn them into a compliant drone. These shells of human beings go about their everyday lives, but they do it without passion or meaning. They remain competent, but they don’t have any real insight anymore, just going through the motions day in and day out. They get their reports done on time, pump out content to feed the social media machine, and continue on as they did before — but inevitably, they lose followers or get passed over for promotion without noticing anything is wrong. 

Integrators hypothesize that the God-Machine only intended the Soulless Algorithm to create the bare minimum of algorithmic drones required to meet its needs. They believe that the rise of AI programs in the early 2020s caused the initiative to spread out of control to the point that the God-Machine cannot reign it back in. Inquisitors and Saboteurs are far more skeptical, assuming everything is going according to plan. Meanwhile, a few morally bankrupt Tempters look for a way to turn the Algorithm to their own advantage. 

Algorithmic Drone

Compliant stigmatic Virtue: Obedient. Drones are all too willing to follow orders from legitimate authorities. Vice: Superficial. Drones take everything at face value, and don’t bother thinking critically.  Attributes: Intelligence 2, Wits 2, Resolve 2; Strength 2, Dexterity 2, Stamina 2; Presence 2, Manipulation 2, Composure 2 Skills: Computers 2 (algorithms), Occult 1, Politics 1, Science 2; Brawl 1, Drive 1; Streetwise 1 Merits: Good Time Management, Omen Sensitivity, Unseen Sense (God-Machine) Health: 7 Willpower: 0 Integrity: 1 Size: 5 Speed: 9 Defence: 2 Initiative: +4 Glitches: The body odor of algorithmic drones smells faintly of brimstone.  Enthralled by the Machine: The drone’s soul has become unmoored, and the God-Machine’s whispers have taken place. The drone suffers from the Soulless, Enervated, and Enthralled Conditions but does not suffer from the Broken Condition as usual. A soul cannot be attached to the drone unless the God-Machine’s influence is first removed. Uninspired: The drone cannot gain or bestow the Inspired Condition by any means.  Unskilled Labour: The drone cannot raise her skills dots above two by any means. If her skills are already above two, they become two until she regains a soul.

Other Drones

The above statistics represent a generic drone who was a software engineer before the God-Machine sunk its circuits into them. Drones from other backgrounds can be created by varying the drone’s skills. If a character turns into a drone over the chronicle’s course, they will pass through the following stages. 

Stage 1: Soulless Art, Soulless Self

When the Soulless Algorithm infects a character, they gain the Soulless Condition. If they are not already a Stigmatic, they become one now, gaining the benefits and drawbacks described in Demon: the Descent p. 225. Stage 1 infectees do not gain additional Supernatural Merits beyond Omen Sensitivity. 

Stage 2: Uninspired

When the infected gains the Enervated Condition, they also lose the spark of creativity that drives morals forward. They cannot gain the Inspired Condition by any means, including by supernatural means. They also cannot bestow the Inspired Condition on another character by any means. 

Stage 3: Enthralled by the Machine

When the infected gains the Enthralled Condition, their conversion into an algorithmic drone is complete. While they retain the abilities they possessed before, they no longer excel at them. The character does not gain the Broken Condition as usual for Enthralled. Instead, all the character’s Skills now have a maximum of two dots. If the character possesses more than two dots in a Skill, reduce it to two dots as long as the character has the Soulless Condition.

Hi, Math Tumblr!

Question first, than I will allow myself to ramble.

Are there names for the families of polytopes¹? Triangle based polytopes are simplexes, square based are hypercubes and orthoplexes, the demicubes are, I guess, demicubes. (I do not yet understand demicubes.) But do 24, 120, and 600-cells have matching group names with their higher and lower dimensional counterparts?

-

Me and my weird little kids love shapes. My youngest also loves collecting and my eldest loves trading (but mostly cubes. Trading is a way to get more cubes). For the last 2 years, I've been making my kids collectible trading cards of convex polyhedra.

If they get a full set (like the 5 platonic solids, the 3 pyramids, or the 8 antiprisms [we don't use any regular polygons above the decagon]) they can trade them in for a special card. In an effort to provide more cubes (there's only one. So it's been a challenge) the special cards are the fundamental complex and regular polytopes in dimensions 3 to 10.

But I don't know much about extra dimensions. My math skills mostly stopped developing when schools brought in the math that requires calculators and ~shiver~ evil decimals. (With a brief glowing resurgence for some aspects of linear algebra in university. Beautiful matrices!) While I COULD just make a set of hypercubes, my completionist tendencies do not accept this. Can anyone tell me if there are names I could use for sets for each of the uniform polychorons?

Additional appreciated information:

Do any of the higher dimensions have a specific term for their polytopes? (Including old terms that aren't often used but sound cool.)

Are there any fun visualization for higher dimensional polytopes? I can use orthographic representations, but anything with pseudo-3D would be more appealing to the kids. Also, do you know somewhere I could find such things online? Currently, I am using wikipedia. I like sets to have consistent visuals with each other, but they don't always need to be consistent with the rest of the cards.

-

¹for the non-math weirdos: 'polytopes' are objects with flat sides (faces). A 2D object is a 'polygon', a 3D object is a 'polyhedron', and 4D things like the tesseract from the Marvel movies are 'polychorons'. You can keep adding dimensions forever.

What Is This?

This is using Tumblr polls to crowdsource the decision-making in order to play through some of the solo adventures from Mayfair's 80's DC ttrpg! Vote in the polls to choose the characters and decide what to do and see what happens!

The solo modules are basically choose your own adventure stories where you read a segment of story, make a decision, occasionally roll some dice and check some matrices, and then go to the next story segment. There may be multiple paths to victory, but there are also multiple paths to FAILURE. Choose wisely! (Or don't! Up to you!)

How does this blog work?

Each decision point will have a poll in order to decide what happens next! Polls will be open for 24 hours (because there are a lot of decision points in a given module). Vote, spread propaganda for your choice, see how we do!

I'll share relevant character sheets with skills and equipment in the intro post for each module, and then add maps or other images as they come up. I'm transcribing the text directly from the physical books I own (as written, occasional weird grammar choices and all).

What if I missed the beginning?

Vote anyway! Join in at any time!

You can also catch up on what's happened so far. Each poll will have a link to the beginning of the game and the previous story segment, and a full list of the entries for the current module will be at the bottom of this pinned post. Modules are also tagged on the post with the title.

What on earth in this game?

This is the DC Heroes Role Playing Game from Mayfair Games! The first edition was released in 1985 (and as a result has some pre-Crisis canon for the characters, which is fun!), with two subsequent editions in 1989 and 1993, plus a TON of extra modules.

(By my count there are 62 additional modules/sourcebooks for this game. It's a lot! My goal is to collect all of them eventually, but so far I have 54, plus the first and second edition base game. Look, everybody needs a hobby.)

If you're curious about how the game works, Wikipedia has a decent summary of the game system, or you can look at a pdf copy of the 2nd edition game manual here. It involves rolling two d10s and then using matrices (plural!) to figure out if you succeed and how much of an effect you have. The second edition box comes with a fun little wheel to help with that.

I have a question about the blog or game system / I want to see my blorbo's character sheet from this game / I want to complain about how voting went

Feel free to submit an ask!

The Matrix Cookbook - Peterson & Pedersen

This one came in as a request from my fiancé, after bearing witness to the blood, sweat and hair-tearing that binding PAPER DOLL resulted in. Fiancé works in academia and this is a useful reference for them, so they asked me to make them a bound copy. I've promised to also do their PhD thesis at a later date, provided they do the spell checking and typesetting. Spotting errors in formulas, plots and dense academic text ain't in my wheelhouse.

The Matrix Cookbook is described by its authors as "a collection of facts (identities, approximations, inequalities, relations, …) about matrices and matters relating to them". Because it's an existing typeset, this felt like a breeze to make compared to other binds. Typesetting is the most labour intensive part of fanbinding for me, although I enjoy it.

This is an 80-page casebound untrimmed textblock with five signatures and handsewn headbands. The paper is "chamois" Q-Connect printer paper which (you guessed it) is a darker yellow IRL than it looked online. Cover is black bonded leather, with leftover green from my Borrasca bind. I'm really happy with the shape of the spine this time around, even if it's not super defined. I haven't levelled up to rounding textblock spines yet.

I printed out a lil copy of my jank homedrawn logo on sticker paper for the heck of it 🐞

This time, I put the bookmark ribbon under the headbands, but it's a little messy looking. The headbands themselves were tricky due to how narrow the textblock is, but adhered reasonably well with the help of additional PVA.

This marks baby's first rodeo with heat transfer vinyl. Unfortunately, this also coincided with the blade on my Cricut wearing out and me not realising. In short: many panels of badly cut vinyl later, I partially succeeded in transferring the tiny author names onto the cover, but mucked up the leather in the process. It's messy, but fiancé is happy and I learned something new.

Sci-Fi Saturday: Doctor X

Week 8:

Film(s): Doctor X (Dir. Michael Curtiz, 1932)

Viewing Format: DVD

Date Watched: July 2, 2021

Rationale for Inclusion:

As mentioned last week, the critical and box office success of Frankenstein (Dir. James Whale, 1931, USA) resulted in a rush to make additional horror and/or mad scientist films. This trend would slow after 1934, in part because the beginning of enforcement of the Motion Picture Production Code sought to limit gruesome and violent content in American movies. The following weeks will include a handful of noteworthy examples of Pre-Code horror sci-fi. The first is Doctor X (Dir. Michael Curtiz, 1932, USA).

The main reason I included Doctor X in this survey, other than being a fan of the film, is that it was shot in two-color Technicolor. The color system, often incorrectly called "two-strip Technicolor", was the third iteration of the Technicolor motion picture color process. The color images produced originated on black and white film where each frame was captured first through a red filter, then a green one. Separate red and green color matrices would be created, dyed cyan-green and orange-red respectively, and in combination during the dye imbibition printing process created semi-realistic color images. 

It's only "semi-realistic" because blues and purples are not reproduced, thus not replicating all colors perceivable to the human eye. This lack would soon be corrected by adding a third color matrix in the fourth iteration of the process: three-strip Technicolor, the famous "glorious Technicolor" of mid-century Hollywood and British cinema.

Part of the joy of going through science fiction cinema chronologically is watching technology advance over time. So far we've gone from silent to sound, and with Doctor X we introduce the first film of the survey shot with a subtractive color process.

Reactions:

Despite the overly elaborate lie-detector and laboratory set pieces in play, Doctor X is more of a horror film than a science fiction one. The main group of characters is a group of scientists and their leader Doctor Xavier (Lionel Atwill) uses a scientific contraption to suss out which of his colleagues is the allegedly cannibalistic serial killer on the loose, but the plot is more concerned with the crimes of the allegedly cannibalistic serial killer on the loose. The film also includes a beautiful woman being menaced by the reporter investigating Doctor Xavier's connection to the crimes, Lee Taylor (Lee Tracy), and the actual killer, in the form of a dark haired Fay Wray, as Doctor Xavier's daughter Joanne. Even before her legacy defining performance in King Kong (Dir. Merian C. Cooper and Ernest B. Schoedsack, 1933, USA), Wray was an established scream queen.

As the film goes on it is revealed that the serial killer was not taking away parts of his victims to eat, as originally thought, but as research samples for creating synthetic flesh. This synthetic flesh can also apparently create muscles, tendons, bones, capillaries and all the other complex structures of the human body because, in addition to using his invention to disguise his face, the killer fashions a fully functional synthetic arm from the magical puddy. It's a shame that this technology is limited to a plot point instead of a core part of the narrative because it is conceptually fascinating. I suppose that's what Clayface plotlines in Batman media are for though.

Interestingly from a production and trivia standpoint is the fact that the horror effects make-up for the synthetic flesh was created by Max Factor. The company was known for its innovations in cosmetics with the specific demands of cinematic production in mind, but its focus was on creating beauty, not monsters. Granted, even Universal Studios' maestro of monsters Jack Pierce had a workload of applying mostly conventional beauty make-up. Specialists in special effects make-up, like Rick Baker, would not exist until after the disillusionment of the studio system.

The Technicolor shows off its ability to display color, but does not descend into what I call "Technicolor abuse," which I define as the use of color for spectacle more than contributing to the overall diegesis of the film. (For examples of Technicolor Abuse see The Adventures of Robin Hood (Dir. Michael Curtiz, 1938, USA) and Babes in Toyland (Dir. Jack Donohue, 1961, USA)) Given the overall emphasis on green in the film's color palette, the red heart beating in the jar in Dr. Wells' (Preston Foster) lab adds to the intended shock value of the moment. Cinematographer Ray Rennahan makes the most of two-color Technicolor's limited range to create beautifully composed, vivid scenes.Doctor X may be more horror than sci-fi, but it's still an entertaining genre flick. It was successful enough at the box office to result in Warner Brothers Studios making a follow up film again starring Atwill and Wray, with direction by Curtiz and Technicolor cinematography by Rennahan, The Mystery of the Wax Museum (1933). Like Doctor X it shows off two-color Technicolor at its best, but unlike its predecessor it's pure horror.

Step-by-Step Python NumPy Tutorial with Real-Life Examples

If you are starting with Python and want to explore data science or numerical computing, then this Python NumPy Tutorial is perfect for you. NumPy stands for “Numerical Python” and is one of the most important libraries used in data analysis, scientific computing, and machine learning.

NumPy makes it easy to work with large sets of numbers. It provides a special data structure called an “array” that is faster and more efficient than regular Python lists. With NumPy arrays, you can perform many mathematical operations like addition, subtraction, multiplication, and more in just a few steps.

This Python NumPy Tutorial helps you understand the basics of arrays, data types, and array operations. It also introduces important features like indexing, slicing, and reshaping arrays. These features allow you to manage and process data in a smart and simple way.

NumPy also supports working with multi-dimensional data. This means you can handle tables, matrices, and higher-dimensional data easily. Whether you’re working with simple numbers or complex datasets, NumPy gives you the tools to analyze and manipulate them effectively.

In short, this tutorial is a great starting point for beginners. It breaks down complex concepts into easy steps, making it simple to understand and follow. If you're planning to learn data science or work with big data in Python, learning NumPy is a must.
