How the fuck does a coder not know what a variable is

>>9838709
>>9838723
Presumably the "variable" part is not the problem

>>9838709
No, but programmers should be able to think abstractly enough to have no problems dealing with them, even if they have only finished high school

>>9838709
Yes but that would require standards which would then cause a disproportionate number of blacks to fail which will lead to backlash over the White Illuminati enforcing a false Eurocentric curriculum that structurally, systematically, and institutionally harms and oppresses historically marginalized groups and ostracizes them from high paying work that propagates life long poverty and continued ghettoization as well as continues the shameful legacy of the cis-hetero-normative patriarchal ideology of capitalistic meritocracy and discriminative educational ableism of advancing those that know over those that don't know which hopelessly falls sort of our collective progressive values of inclusivity and diversity.

Of course people will always be afraid over change including getting rid of education curriculum but it is for the advancement of our greatest ideals and values that should (and must) happen. Remember that we are the future, we are on the right side of history, it's 2018.

The saddest part of this is that even front-end webshits would have to work out scaling factors in their heads, or at least write functions that use them!

Drunk right now so I'm going to rage at you. CS is a great major and you will have a good life if you major in it. Have fun making $30k because you can't get a job with your math degree. Have fun having to get a PhD to make as much as CS majors do

It's amazing how sheltered college students are.

Average people can't creatively apply middle school math. If you had paid attention in school you would remember the insane focus on just teaching the bumbling retards a bunch of procedures they have to memorize and follow to the letter to pass tests, which they often fail anyway.

I'm an engineer learning machine-learning for fun. Literally, just for fun (and maybe job opportunities.)

First hand experience, there is no possible way a normie could ever learn this stuff. If you can read up about a perceptron and implement it in any programming language you are 1% of humans who could do that with their current skill set. You are 0.01% of people who even know what I am talking about.

Sometimes I think /sci/ is just so disconnected from the real world that it's laughable. The normies are at the pool today.

You are literally part of the flood. Look at the views machine learning channels are getting. The field is already mature, the big players are in, and now dumb normies like us are finally learning about it, 20 years behind the curve. You can find whole courses, freely available online, teaching utter brainlets like us how to make a neural net with no understanding of any advanced math concepts. It's been watered down and sanitized. Machine learning is babby's first html page tier nowadays

*imports tensorflow as tf*

For an engineer like myself who learns online for fun, this whole machine learning thing is no match. For normal folk though? Completely impossible. I'm part of a gifted few. The elite. For me, mastering a domain like this takes only a few hours of Youtube tutorials, and I have it down. Not a lot of people can say that.

>>9840416

>>9840584
Haha yeah bro. You won't believe this, but I managed to write an image classifier that NAILS the MNIST data set with over 92% accuracy, only using tensorflow!

Hey /sci/!! My wife's boyfriend just bought me a copy of "Machine Learning for Dummies" on the Nintendo Switch. So awesome! How long do you think it is before I can start making six figures? Basically I want to be a data scientist for Google or Microsoft. I took some CS courses at community college but dropped out because they wanted me to take pre-calculus again (even though I passed it in high school?? Idiots lol)

>>9840559
Well as I was 8 years old 20 years ago; i'm not sure how you expected me to master neural networks at that age. Once again, a sci-tard creates impossible standards and is upset nobody can obtain them.

The machine learning videos from Standford on Youtube average less than 100,000 views. How many do you really think are breaking into the field? Lets say half of them make it which is a big if. You are saying 1 in 50,000 humans understand machine learning. It's a barely saturated field for a reason. Come back in another 20 years and argue the flood has started.

Yeah, well, so were many of the guys pushing the limits. But unlike you they got into college at 14-15 and got scouted by the tech companies starting to do it as a business. There is no place for you, or I, or anybody who is just now starting out.

Narrow fields that are about creativity can get saturated really quickly. How many people are engineers? Yet the job market is utter shit in most of the western world and the field is flooded with low paid 90iq pajeets.

What does that even mean? That there are no more Edisons, Gates, Musks, or Einsteins in the world? If a genius is going to be born it's likely he will born from 1990 to 2040 just by sheer numbers alone.

>>9840681
you are not that genius, the 15 year old PhDs are.

I'm not saying there is not going to be another bubble or another enterpreneur, I am saying that machine learning is already underway and you're late to the party. Maybe you can get in on something else, but it's unlikely since you're so far behind the curve. Don't worry, you're not the only one, but don't delude yourself. Look at how common and trivial machine learning is nowadays. Any s o i boy with a masters in engineering has put together a few machine learning startups nowadays.

>>9840686
Your motto seems to be since I can't be the best don't even bother learning. I might as well quit working out too since I'll never be an Olympian.

>>9840708
Not him but I get what he's saying. What's your plan exactly? Land a job as an ML engineer? How are you going to beat actual experts to that position with your "for fun" learning and a completely irrelevant educational background?

There's a gazillion people who want to do the same thing as you, and half a gazillion who have actually pursued the correct qualifications by now and will beat you to a job every time (since you missed the early-entrance window and can no longer ride a shortage of trained professionals into the market)

Working out despite not being the best has the potential to create tangible benefits for you. Your vague, surface-level interest in another field does not

>>9840723

I'm in controls engineering. I'm as close to machine learning as an engineer can get without being a ML engineer.

The reason why maths exist is to give teachers employment so they can teach their hobbies and to make schools more money. It's not fair for middle school and college students to learn math when most are never going to use it.

>>9840835
The state of education everyone.

Math is useful for more than you can possibly imagine.

>>9840914
Give me a real life example whereas learning Algebra would help a person.

>>9840919
do you mean high school algebra or college algebra ?
HS algebra you use literally everywhere. If you need to be explained why knowing proportionality, affine functions and logarithms is useful, you are clearly unfit for managing your finances.
Linear algebra is not as obviously useful to everyday life, but it is the foundation of all higher math, pure and applied, including all numerical methods for differential equations (many of which boil down to inverting, computing powers or eigenvalues of matrices in the fastest way possible) which have many very real applications (basically any sort of mathematical modeling).

>>9840919
>proportionality, affine functions and logarithms is useful, you are clearly unfit for managing your finances
Wow, really just for those three things? Is that the crux for your rebuttal? You want pre-teen and teenagers to go spend six years in school to learn those three things just to learn finance when they can just pay somebody who works in the bank to do those things?

>>9840919
>Give me a real life example whereas learning Algebra would help a person.
It let's everyone else know that you're not so stupid that you can't understand algebra.

>>9840979
>If you need to be explained why knowing proportionality, affine functions and logarithms is useful, you are clearly unfit for managing your finances.
Is it crazy so make students to take algebra for six years just to learn finance when they can just ask somebody who works in the bank to do it for them.

Also, most students never go to higher levels math or do any sort of mathematical modeling.

>>9840991
are you retarded? there's a lot more, but "just those three things" can go a long way, you want to make a budget? you need algebra, from shopping, to insurance, to retirement, you absolutely need algebra. Or you can pay someone, that someone knows algebra and you are losing money because you are too much of a brainlet to learn basic math.

You want to open a business? same deal, what are you selling, what you should buy, how much can you expect to grow/earn each month?, not knowing this is a good way to go broke.

You saved some money? should you invest? where? how much can you expect to earn? are you taking shit like inflation into consideration? all baby equations, and proportions, but really fucking useful. Math is literally THE tool for modelling, you can use it everywhere.

>>9841023
>take algebra for six years
>6 years

More like 6 months if you're a 1st grader with ADD.

It would make my life a lot easier if people were expected to know basic algebra.

Lambdas basically generate a unique class named lambda_4350984_3458 (random name each time it compiles) and the lambda function is a member of that class. Like this

class Lambda_34895_6542rfi4u5t3_4358
{
static int impl(int x, int y){ return x + y; }
}

Using the auto keyword on parameters like that makes is so that the member method is a template function taking arbitrary parameters. It's pretty cool how these new features aren't even random shit hard-coded in, they instead just fit with the existing language behavior. Like this

class Lambda_843598_54o86735849_943
{
template<typename T, typename U>
static constexpr int impl(T x, U y) { return x + y; }
}
