Even a huge believer in technology like me has to laugh when some character talks about how they’re going to change the world with an app that tells you whether what you’re eating is a hot dog or not.

sorry bill but one could argue in a round about way that andrej karpathy did do just that ;P

the hot dog identifying app is one of my favourite examples of how spot on the show is

here(o) is a question i asked to one of the show's technical consultants whether the choice of 'not hotdog' was a reference to one of karpathy's early demos(i||ii)

timanglade> Ha seems like a fun coincidence.

I would argue you make it a mandatory piece of the curriculum for voting age, or to be, high schoolers

Researching and reading all of the supportive material for a ballot's fill of decisions is a skill and effort

Detailing how to develop that skill and establishing that effort as habit could affect students to continue to keep an interesting in voting

Take your time with each element of the next vote's ballot

let the students discuss multiple viewpoints and coach a civil fact based discourse

fantastical speculation inbound..

dragon ball super(o) recently made me think that in a world where teleportation is possible we could just teleport the baby out of the womb, avoiding the pain of labor

of course there is still the hardships of carrying the child, and who knows what kind of havoc such a sudden event would cause to the mother's hormones

how much of the bodily functions associated with labor are evolutionarily built in necessities of human reproduction? do cesarean births have any hormonal consequences differing from vaginal birth?

i advocate for computer education being complementarily folded into the current math curriculum

i have interest in changing the math curriculum as well, but for people who like the current math curriculum I think there are enormous benefits of teaching computer skills.. science.. through implementation

HA! that is exactly what this is.. my bad

i had thought the shorter clips were just that, clips from the 3b1b videos, but when i decided to click through it's much more than that

they are calling it explorable video

the videos are fully interactive.. this is awesome!

i'm unsure exactly how frames are drawn..

the repo has a number of custom self defined objects that allows for pretty abstracted handling

it appears the frames are drawn ad hoc using PIL, SVG and or cairo libraries with the spatial reasoning done explicitly in the source

oof, the one thing i am wont to want with 3b1b videos is an interactive suite accompaniment.. unreasonably ungrateful i know ;P

i had high hopes this would be it, but this is just a concise lesson form for the series.. which is great! i am a huge fan of both eater's and sanderson's entire ouvre

what's great is that 3b1b releases the code that generates these videos and i have cloned the manim(o) library a number of times in the past when a video had an idea i wanted to play around with but the effort usually gets a low priority and i get distracted with more pressing projects

i figure a simple localhost python server serving up dynamic frames generated by manim could do the trick, maybe i'll work at it again this weekend

when i want to learn a new mathematical concept i like to write the source myself, which is great for getting at the nuts and bolts but it is usually after i have done this and start to tweak the models or constants that i begin to gain a real intuitive understanding of an underlying concept

it looks like all of your links are basically only addressing my initial list item

the first link is about modifying a system's c compiler which the op's tails live usb is infact a solution to

the second is about altering firmware on harddrives, which is an engrossing writeup, thank you, but does fall short of suggesting ways to identify and remedy such an invasion

your third one is about intel's ME which i figured i'd see someone link to

unfortunately, the really interesting listed elements in my original post are the preventative and resolutive elements

sounds horrifying

can you point to any resources on a few things:

(o) examples of these kinds of malware, either code or writeups

(i) ways of detecting these kinds of malware

(ii) ways of removing these kinds of malware

(iii) ways of preventing these kinds of malware from getting installed

i hear you

electricity should be treated with respect

but i made a point to emphasise that the majority of problems are blown capacitors

this is a prevalent problem(o) that is easy to diagnose and easy to fix

for the listed examples my only diagnostic tool was my eyes, when a capacitor blows you can tell.. that is it looks like it failed in some way

to replace it you have to desolder two connections and solder in a replacement

the capacitors usually give you all of the information you need right on them: capacitance, rated voltage, positive and negative lead; so without needing to know what those things are or why they are important finding a replacement is straight forward and replacing is plug and play, with a bit of solder, if you keep track of how the original was oriented

but like all things it takes time to get comfortable and you get better with more exposure, which is why i emphasised a desire for basic ee to be a part of early education

first time i worked on a car myself i was driving on the highway and my car just stopped, roadside said it'd take 2 hours to get to me, i was unfamiliar with car mechanics but i thought 'i'll just look at it and see if i can see what's wrong, maybe i can fix it', i popped the hood and looked at the engine, it a took a minute to suss it out but when i found the problem it was glaring, the air intake for the engine had popped off, the screw band had rusted and failed, i just pushed the tubing back on the intake pipe, used a dime to screw the rusted band on enough to get me to a hardware store to replace the screw band

i knew i'd be unable to disassemble the transmission on the side of the highway, the first time i opened a car hood, in less than 2 hours, but those expectations were too exaggerated, all i had to do was push a tube on a pipe

i think repair cafes are less about having an in house solution to all problems and more about having broad solutions to the problems that occur the most, and like a bike cafe it could be a hands on experience where there are people there who can help, showing you how to troubleshoot and repair

a film called manufactured landscapes(o) completely shook me when i saw it in theatres when it was first released

the film addresses ewaste issues like the fact that a lot of electronics rely on toxic elements, but there is also the shear vastness of dumpsites

there is shot of a dump of motor armatures which could be argued to be one of the least likely failure points in consumer goods that use motors like washing machines, blenders, drills, et al

the film was even released in 2006, one year before smartphones become a cultural ubiquity

it is also wild to think that most of what is being documented is a result of manufacture happening only over the previous 50 or so years.. which is only 0.00025% of the hypothesised almost 200k year human history

it is a film 'documenting a photographer's technique' so retains an air of lacking bias but the subject matter is just so affecting that audience bias becomes seemingly inevitable

you could just as easily goog 'ewaste concerns' and find a myriad of issues but i highly recommend this film.. i was in awe from the opening sequence

precedent is a court document

you linked to an article pretrial

the person in the article took food from a bin stead ewaste

i tried to find a followup article or court decision but was unable

i did find a similar article from iceland where people were charged under an 1824 vagrancy act which was ruled unworthy of prosecution(o)

your linked case reads like a power tripping manager to me

this practice was part of the squat culture as well: every few days we would do a 'skip hop'.. skip being the term for a large trash bin.. we'd go to grocery stores who were legally bound to throw away food that expired that day at the end of the day as well as forbidden from giving away 'rotten' food, so the employees would stack the food items carefully in separate trash bags from the 'actual' rubbish and put these bags next to the bins

pageantry of plausible deniability is a hilarious thing

ha! depressing

though i doubt the people i was living with who would break into abandoned buildings to establish residence are all that too concerned with your rubbish 'theft' precedent

the tablet salvage was in the states and unfortunately i'd be unsurprised if there are equally uncharitable precedent here as well

.. as an aside, i would be interested in reading your referenced precedent, i agree going through someone's bin to get personal info or to file false credit card offers on their behalf should be illegal, but i'd be interested to read the ruling if it is literally a broken electronics salvage

i've fantasised about something like this before

my neighbors are consistently throwing away perfectly fine electronics where 90% of the problems are a blown electrolytic capacitor

there is a place in our apartment complex where we place electronic rubbish and just two days ago i noticed a tablet with a destroyed screen

i popped it open and everything inside looked pristine so i bought a new screen for some ~20$ and am now waiting on it to arrive

i've fixed a toaster oven with a busted resistor, 50in plasma tv with a blown capacitor i now use as a monitor for my laptop when working at home, a blender with a broken container and blown capacitor.. an older blender model that actually has a standard thread size so i am able to use mason jars as a, what i think is superior, container

i think repair should be taught in schools, a la 'home ec', educationally its a three`for : repair, basic ee, basic applied maths

when i was living in squats in london part of the squat culture was to slowly accrue enough bike parts in the hope that you could one day open your squat doors as a bike repair cafe

i have thought quite often something similar for basic everyday electronics would be great for educational and environmental concerns

there is so much unneccessary eWaste, even if something is beyond simple component swap repair it can itself be used to source parts for other fixable devices

the idea that we toss away a salvageable device, or even its sometimes hundreds of functioning discreet components, because of a single blown capacitor, frayed wire or dislodged headphone jack is upsetting

you forgot ip contracts

i recently had a company try to have me sign a document claiming ownership of anything i create in the time i work for them; meaning the tenure

i asked for clarification and without flinching they asserted that, 'yes, that includes on your own time and your own hardware even in a field wholly disparate from the one the company was in'

i thanked the interviewer for having me in and explained that though i felt they seemed like a kind person the company they were representing was offensive and unethical

first time i ever ended an interview early

You can contest facts, he said, but not images.

with the ubiquity of photo editing, and ai driven video manipulation, i'd argue one can contest images too(i):

> Ghost in the Shell addressed this issue in 2005(o) > The Tachikoma units are debating how to stop a nuclear strike and one suggests that broadcasting a live feed of the nuclear sub would help, but the idea is reasoned against due to the technological capabilities to fake such a feed: > "Pictures don't prove anything anymore. It would just end up as a source of amusement for the uninvolved masses, an image from an unknown source that showed up at an all too convenient time." > beyond this inflection point one must now trust both the content and the source

there are a couple definitions you would need to elaborate on to realise this question fully

by particle physicists usually mean any electromagnetic phenomena that seems to have distinct energy levels and so can refer to any number of things depending on context: photons, electrons, protons, atoms(o)

as for interact, what do you mean by this? would you consider entanglement an 'interaction'? the idea of a wavefunction is basically that every particle is 'interacting' with every other particle in existence in every direction with potential of collisions being discernible by the probabilities of the particle's position being spread out ad inifinitum

according to relativity light has a constant speed, meaning it is always moving at 'c'

since the photon is moving it has energy and though it has a 'rest' mass of 0 it is without a rest frame because it is always moving at that constant speed and so always has some measurable mass

because of this even in a universe with only a single photon without anything to interact with the photon would still affect spacetime

if you remove the 'only' from your question then the answer is an emphatic yes because you yourself are a collection of 'particles' 'interacting' and you are affecting spacetime

i built something similar for a home project

i ended up taking it down due to concern of having all of that weight above me

when a huge mass is suspended above you the potential gravitational energy becomes very palapable

seems logical.. i would argue the inflection point in the ubiquity of pooled compute services came as bandwidth needs increased due to more businesses interacting directly, remotely and in real time, with customers, be they consumers or other businesses

if compute needs were all internal, as they are with desktop apps.. namely, compilation.., and with the majority of computationally expensive machine learning demands.. namely, training.. then i'd argue the pooled compute model would have remained niche

The description that General Relativity puts forth ... needs to be augmented to include an uncertain position that has a probability distribution to it.

i am sorry but 'needs' is too strong here

quantisation(o) was established before, necessarily so, probability was introduced to explain the behaviour of electromagnetic phenomena

to claim that probability is necessary for quantisation seems to have it reversed

the current understanding is both unknown whether gravity is quantised but also whether probability is necessary to describe quantum behaviour

with current understanding the only thing one can say with certainty is that requiring probability is a result of the math used to best model quantum behaviour of electromagnetic phenomena, namely fourier analysis(i)

i learned to surf as an adult

it can be a supernatural feeling.. paddling hard until the moment the wave picks you up and says, 'i got you from here' and just carries you off

when picking a board you should know the bigger the board the more stable it will be and the more forgiving it will be as you stand up, ~40-60cm taller than yourself is a good rough metric for a medium sized board, you can start bigger and as you get better try smaller and smaller boards

i have been body surfing and boogie boarding since i was a kid so, unfortunately, i am unable to give you any good tips on picking a good wave and figuring out the timing, but i think this may be a skill that can develop on its own with time

as for the surf.. the best advice i can give:

1) when waiting for a wave: stay on your board; the more time you spend on the board the more intimately you will get to know it and the more you will develop your stabilizing muscles and core

2) when paddling for a wave: arch your back as much as you can to lift your chest off the board; it will look like the 'bhujangasana'(o), or 'cobra', yoga pose and this helps to keep the board level in the water and allows for more strength in your paddles

3) when standing up: look down at the board to ensure you place your feet in the center; early on i had the tendency to look up at the shoreline and would place a foot a bit off center and the board would flip

4) when standing up: bend your knee and plant your back foot first; early on it was more natural for me to plant my front foot first but bending your knee and planting your back first ensures your center of mass is directly above your foot

5) once stood up: keep your knees bent; this keeps your leg muscles activated allowing for better balance and control

of course, most important: have fun!

gp> it’s a calculation which proves there is indeed a complexity point whereby quantum computing will exceed classical computing

'Prove' is correct for the research but a bit strong for the language of your summary

The important caveat:

tfa> determination of the smallest computational task that is prohibitively hard for today’s classical computers.

'today's classical computers'.. or more timeless: 'contingent on p!=np'

I've wondered something about dreams that if taken as explanation is very similar

Conjecture: during sleep the mind moves short term to long term memory, when formed, the memory fires adjacent nuerons and these fired nuerons form the dream

In your case, seeking an old memory may have fired other adjacent nuerons, perhaps ones that have been dormant for some time

I will do this when trying to remember something.. think around an memory and my own exposure to it contextually hoping to indirectly find the desired memory
