but for product reviews or political things there's definitely an incentive to make real-sounding posts that are fake.

for basic sentiment analysis, maybe. but any slightly discerning person can tell fake reviews, or at least reviews that aren’t useful. when someone starts talking about how they like it a lot but the button has a weird catch to it, oh but here’s my workaround you can tell it’s real. ai reviews will never be able to go deep enough in detail that reveals idiosyncrasies of real people and signals that this is a person who interacted deeply with this product

for banking i use gmac ally, which has been pretty decent actually even if not having any physicality can be annoying in a pinch. even before interest rates were popping off they were very generous

wait you know about the gmac to ally name change and still went with them? they changed the name because they had such a bad reputation it was toxic to their business

wait a loving second the assignment mightve just told me how to do it
i can just have an "occurances" attribute on the nodes. find one node and just check its occurances

that sounds exactly right, yeah

probably something like have a tree with occurrences property on each node, and when you load the data into the tree check if a node exists. if not, add it with occurrences set to 1, otherwise find the node and add 1 to the current occurrences count.

btw how the gently caress do i calculate big o notation they never taught us that (just that it exists)

this is a big question because the “secret” of computer science is that the whole subject is essentially minimizing the big o. data structures? you pick ‘em based on which has the smallest big o. search algorithms? again chosen based on if you add data more often or if you lookup data more often - and thus by the big o of adding or searching for stuff. in the end there tends to be about 5 commonly used values.

constant big o - O(1) - this is an array. look it up in ~1 operation each time. amazing.

logarithmic big o - O(log n) - grows real slow! log 2 is 1 but log 8 is only 3. log 1000000 is only like 7 or 8. very good, this is binary search trees

linear big o - O(n) - pretty fast until you get to big numbers. easy to look up when you have 10, less so at a million

n logarithmic big o - O(n * log n) - log grows slowly, then you multiply by a constant. grows sorta quick but not bad. this is like doing a binary search on each character in a string (n characters, log n searches for each character)

polynomial big o - O(n^2) - uh oh. this grows fast. n of 10 is 100 but n of 100 is 10000 - the more you have the worse it does. go back and find an n log n algorithm unless you have like less than 1000 elements.

exponential big o - O(2^n) - oh poo poo. this grows fuckin fast you are in trouble. this is the land of traveling saleman, and if n is 100 it’s gonna take years for a computer to calculate. you hosed up if youre here

calculating it takes math or, later, intuition. why is a binary tree O(log n) for search? because each time you move down from the root you eliminate roughly half of the possible values you need to check. so if you have 8 elements, you have 3 levels and go from 8 possible to 4 possible to 2 possible to the value. log 8 is 3 - you went down 3 levels in toys search so O(log n) where n is 8.

But! worse case for binary search is O(n). why? you might have inserted the data in the exact order where the tree forms a line and degenerates to a linked list and so you don’t do the average 3 searches, you do 8 because the value you are looking for is the last one in a line of 8.

from there you learn how to map an algorithm’s shape to big o. if there’s a loop within an outer loop? probably looking at O(n^2). and so on

i think im missing something because none of this is actually helping me to calculate anything. it's just telling me what certain predefined algorithms are
someone said somewhere its the amount of lines it has to run, which makes me think its just the line count (minus whitespace) plus however many times loops have to iterate, worst case???

the secret to all this is think in terms of 10 and a million. how many times through the code does it roughly take if you have 10 things? now what if you have a million things? some algorithms will take 10 and a million ( lines executed, time units, whatever). others will take 1000 and 10 billion instead. determining how much longer or how much more space an algorithm will take as n goes from small to large is what the big O value tells you.

it’s a measure of efficiency as you go from small numbers of stuff to large.

DELETE CASCADE posted:

the key thing to understand about big-O is not just that it's looking at the worst case, but that it's looking at the asymptotic behavior, meaning the behavior as N gets huge

this lets you wave your hands a lot. those lines inside the loop? they probably don't matter. whatever small operation they are doing will be dwarfed by the fact that you are looping over N elements, and N is huge

however this does not apply if those lines inside the loop are doing something like "loop over another data structure that is also of size N". then they matter

actually doing the math here involves limits of infinite sequences and other loving annoying bullshit that i forgot as soon as i could

this is a good post. put another way if you have an algorithm that does 100 lines of code n times vs a different one that does 1 line of code n^2 times, the second one is way worse when n gets big. if n is like 4 it will kick the crap out of 100*n, but at n = 1000000, 100*n will be the easy winner. it’s about how it changes (or dominates?) as n gets big

alright so this first one takes a user-provided number and then iterates two nested for loops that many times, so... O(n2)?

i mean it also does some other poo poo but that doesnt seem to make anything iterate so

sounds right. the key is that the other poo poo matters a lot when n is small, but what if n was one billion? now that’s a shitload more than n*the other poo poo

if you’ve survived in the industry for 5-6 years you can absolutely figure all that stuff out. it means you have soft skills to get along, and now you just gotta work on tech skill stuff. read Wikipedia, or better perhaps, look for illustrated in-depth blogs about b-trees or red-black trees or whatever. the concepts are not difficult, they are trees that just have more complex rules to keep them balanced - which is another word for making searches quick guaranteed. read one article a day, that’s 20 in a month. 240 in a year. small steps add up, don’t let anxiety gently caress with you

that’s very interesting because I have some mild form of pots and looked into reynaud’s in the past. I suspect there’s more to it regarding eds and collagen and tissue and genetics where a very mild form(s) are present in many people. but as usual medicine doesn’t understand the body well as has to start from the extremes by finding syndromes and then works backwards towards harder to uncover causes so this goes unnoticed (we only notice stuff that “disturbs” your health or ability to work)
