I give up.

I guess that I deserved it, I did forgot a comma at line 101 and the endmodule declaration at line 132 cuz I was too busy minding if I connected the modules correctly

Even though I know how it works reasonably well now, to this day, I still feels like that automatic differentiation is pure magic. Especially considering its applications and implications.

Really reminded me of the rheostat they taught us how to use in middle school.

The rheostat I played with as a kid and the Delay-Locked Loop I played with as an adult...

Found this screenshot of the Bolzano-Weierstrass Theorem while scrolling through the countless screenshots our AuDHD brain took then promptly forgot:

Well looking back, I can't help but to remember the Poincaré recurrence theorem. That's it really. I don't have more to say.

TIL: Let's say here's a simple piece of of C code:

struct node{ int data; struct node *next; };

and now we do this, because we're too lazy to manually set the next pointer to null:

struct node *n = (struct node *) calloc(1, sizeof (struct node));

while calloc() is guaranteed to set those bits to zero, the null pointer is NOT guaranteed to be (stored as) all zero, and while this code will run just fine most of the time, it's NOT correct.

Once a friend of mine quipped that she's just like DRAM; she's [so perpetually tired and] needs to be refreshed all the time.

I thought for a moment and replied: so, if I refresh you fast enough and in a specific pattern, can I trigger a row hammer?

Her honest reaction: remind me to not get on your bad side [scared emoji]

(for those who don't know what the row hammer is:)

Why MIT CSAIL is (afaik) not on Tumblr, I want to reblog this so badly

[cascadingcascade]

Hello Tumblr, it is with great sadness that I announce that due to academic stress and some triggering events (I wasn't fronting much recently, she's the only one who's decent at math and has to front continuously because exam season), our resident math nerd stress split last night and our new headmate has a lot of unmitigated aggression, she won't even talk to the rest of us and has been beating us up, while I'm typing these words on our phone I'm basically running and hiding from her in headspace, oh well

I can't blame her can I, I was forced to front continuously a month ago because my headmates can't handle some stuff, and I stress split too and did some really stupid things (that's also kinda triggering both for myself and others so we're not going to talk about it). The new headmate disappeared/merged back after we recovered a bit and I just hope it will this time too

Also since we're all pretty tense and stressed out, I hope it won't snowball and turn our headspace into a complete dumpster fire

Actually it would be kinda funny if were not for how dark it is, plural chain reaction: stress split causing more stress& triggering events and more split, releasing huge amounts of unspeakable things just like nuclear fission. We're definitely going to joke about it once we're recovered enough to joke about such things

This is a intro post

"Icarus never was a parable about the limitations of humanity, it's a parable about the limitations of beeswax." - a quote that while represents only the personal belief of one of our members, is agree upon as reasonably cool

This is a personal blog, owned by a plural system that don't really have a system name/blog, so we put Ashley's name there. For the most part she operates the account too (and our accounts on other platforms), and posts made by other members goes through her first (we have a ton of drafts she didn't approve just sitting there) so we guess it's appropriate?

More details&rambling below the cut:

We have three members, we think. All of us are (trans) girls and uses she/her. Since we usually only interact with other people in each member's individual capacity, there's really no need to address us as a system unless we're doing it ourselves. We probably should sign off our posts too, but we are not really sure if it will be understood/well received by people outside the plural community

Our (most commonly used) names are Ashley, Ellie and Sharon. Yeah they're all stolen because stealing names is a time honored tradition among trans girls and we literally don't know how to come up with original names. Blame the autism if you will. But no, our personalities/appearances are original and completely unrelated to the people/fictional characters we stole our names from.

We are traumagenic ourselves (don't really want to talk about it, we got absolutely horrifyingly and continuously abused for more than two months before we ended up where we are), but we're open-minded about endos, please don't argue with us about it, we're of the opinion that we'll know fakers we see them

We are autistic AF, with some ADHD too, but we still can't agree on how much ADHD we actually have and what's caused by ADHD and what's not. Special interests differ between members, but most of the time you'll probably see us being a math/computer nerd

Our gender/sexual preferences vary by member. Some of us are transbian, some are autigender/ace. By the way physically we're 20 years old.

Saw some people playing Stardew Valley, and I can't help but to think, if in real life, we have simple and unambiguous social signals like in the game, giving somebody a flower bouquet means you want to date them (and nothing else), life would be much easier for us autistics. When I say something I mean something, literally, why can't neurotypicals do it? Speaking in a roundabout way gotta be harder than being straightforward, right? It makes no sense. And why, when I explicitly said I mean something, neurotypicals STILL act as if I mean something else neurotypical-y, that I'm just being courteous or something. I mean I literally told you that, what's so hard to understand about being told in a literal and straightforward way, it also makes no sense.

But nooo, in real life, not even "talks to you at length, (as sincere as I can ascertain at the time) compliments you repeatedly, and asks for your contact information" means "they want to befriend you". Yeah, that happened to me a few days ago. I was so excited thinking I am finally going to get a new friend. Was.

I have around a dozen friends, all of them would rate at least "somewhat autistic", and three or four of them are outright hardcore autistics. It's not that I don't want neurotypical friends, but every time, either it won't happen at all, or in one case, we were casual friends for awhile, then he just can't handle talking in a straightforward, "when I said it I mean it" way and told me that I'm so rude and quit.

I was reading some Halloween themed programming jokes, then it suddenly hit me: "trick or treat" is not logical or at all, it's a Cartesian product: {treat, ¬ treat} × {trick, ¬ trick}, and presumably ¬ treat ↔ trick

Update: I looked around for how to input superscript/subscript, and found another very interesting solution:

But unfortunately it does not appear to be compatible with Samsung devices for whatever reason, as both my own testing and the issues section on GitHub would indicate. I don't really know about Android development, but I took some glances at the code, combined with my own experience that the service usually works once and only once per app start, my guess would be that the system killed the service's listener and won't let it recreate the listener again. I really should've bought a Pixel.

I googled "how to type the integral symbol [filled by suggestion: in mobile keyboard]" and this is what Google gave me, what can I say

But fortunately I found a much better solution:

Got an algorithm and data structure exam question where I am supposed to code an algorithm that takes a singly linked list node and sorts the list today. I imagine that the 'correct answer' is to repeatedly transverse the list and insert the minimum node into the front, just like insertion sort.

But I cannot help but to notice how unrealistic it is. I mean, in reality, we don't just use naked linked list nodes, the linked list object we encounter in the wild has memory pool and various bookkeeping, all access to the underlying data structure are encapsulated. If I am asked to implement a linked list from scratch and give it a sorting method, I would just garbage collect the memory pool as needed (or design the comparator function so freed nodes are automatically considered the largest/smallest and moved to the end, where they can be deallocated easily), do a quick sort on the memory pool (which can be random-accessed), then re-link the whole list.

But nooo, it's a (pretty tightly) time limited exam, and I am not allowed to change the function signature, so I said screw you and made a quick and dirty solution that pulls all data into an array, sorts the array then puts the data back.
