The Ex Machina movie that recently hit theaters has a moment where the protagonist asks if the robot was designed based on his porn profile. He was querying the creator of a Google-like search company.

Google should totally be spending R&D on that instead of augmented reality and self driving cars.

In retrospect, while I am very glad that I dropped/washed out of my PhD program with a Master's, I am also very glad I went. I learned a lot, both through coursework and research, and many of those ideas have been helpful in my work. Now, it could be that my work is more theoretical / mathematical than most. But I am always very skeptical of programmers saying that "everything I needed to know, I learned on the job", because even in my fairly short career (10-15 years, depending on what you count) I have met an awful lot of ignorant, bull-headed programmers. I've known quite a few excellent programmers who never even finished undergrad, or didn't study programming in school; but in every single case they saw that as a defect that they needed to fix, usually just by studying independently whatever they'd missed in classwork.

What's even the point of a CS master's or PHD unless you're really into research?

Personally I went into the PhD because I did undergraduate research with a passionate young faculty and loved it. Then I came to grad school, ended up working with a senior faculty/administrator (on some very cool stuff never the less). Yet I realized that the whole process is as much of a pyramid scheme as people describe, it is much less about he advancement of science than it seems from the outside and that industry is actually more intellectually challenging while being much much more rewarding. Most folks in PhD programs that I've met (excluding those from top 5-10 schools) are less outwardly intelligent, less motivated, less social, less productive and much much more miserable than the majority of people I've interacted with in industry.

The problem is that I realized those things about three years into my PhD and after turning down a job offer at a big three firm. So I grinder for another three years. I don't necessarily regret my choice (starting a PhD is what got me in the U.S. In the first place). But if I were to do it again I'd do it differently.

So yeah, if your TA has issues, he's depressed and probably on the verge of a meltdown, so cut him some slack.

There's something really sick happening to universities in general and I'm not really sure how to fix it. The problem you describe extends well beyond CS postgrad stuff. It's even worse in some fields where you're not considered even equipped to be entry-level until you've got your first doctorate.

Some disciplines there is just a lot to know, when I did my math phd the first 3-4 years were solid coursework, and I came out with huge gaps in major areas (I had no graduate-level algebra or topology classes, and only one semi-formal graduate number theory class).

PhD is just a 5-7 year low-paying job that lets you work on really cool stuff you probably otherwise would not be able to do fresh out of undergrad. (If you're doing a PhD, you don't want to be a professor, and the previous sentence does not describe you, you should probably get out now. There is no other payoff.)

For me, it was compilers and PL design stuff. I had a blast.

I'm a PhD student in AI/Machine Learning, way more heavily towards the former side (I deal with decision making and planning, imitation learning, and some simulation). I'm sure I could've probably tried to get a job at some company doing data analytics or something, but grad school was my plan since undergrad. I'm probably "underpaid", but I also get to work on making computers play games and poo poo. The market for the stuff I like to work on is pretty small. Some video game AI is within what I do, but the stuff I like to work on is closer to "the creature in Black and White" or "The Sims", and not what 98% of games use for AI. Not to mention I hear the game industry can be almost as exploitative as academia.

The closest to the type of jobs I'd like in industry are closer to "Mars rover pathfinding" or "Google car", which seem rarer and harder to get than platinum*, at least with only a BS, so I have a sweet gig working on the stuff I like as a student. If I can't get a tenure track position (likely), I'll basically be hoping I can eventually find something like that. Writing web anything or predicting what consumers would like to watch next on Netflix is my hell.

* I guess there's some industrial robotics, which really isn't my first choice, but I suppose it's vaguely in the realm of what I do.

You want to return a boolean, not a number such as 0, 1, or 1.5. Also n % 2 returns a truthy value when n is not even.

Clearly you all have been blinded by these worthless dynamic languages and need the power of a good static type system!

code:

#[derive(Debug,Copy,Clone,Eq,PartialEq)]
enum Parity {
    Even,
    Odd,
}

fn parity(n: i64) -> Parity {
    if n % 2 == 0 {
        Parity::Even
    } else {
        Parity::Odd
    }
}

fn isEven(n: i64) -> bool {
    parity(n) == Parity::Even
}

The real horror is that I'd probably actually do this.

Julia auto-promotes ints to floats for division, but there is a special operator for integer division. It seems to work pretty well there, but then Julia is also a scientific computing language.

IMO that's actually pretty reasonable.

I was playing with this example though and I was trying to figure out how to make it generic over the Rem trait. What's the Rust way to cast the 2 to the appropriate type? (The fact that I can't figure this out probably means that I am the coding horror)

Nah, I couldn't figure it out either and gave up, changing it to i64. I figured it wasn't worth it for a silly throwaway code block on an internet forum. I got stuck on the same part. I guess you could do two using One + One from the num crate, but that'd be pretty ridiculous.

E: You're right that it's probably not terrible, but unless you're going to do something interesting with Parity other than an evenness check, it's probably overengineering.

Best way I could figure out, short of doing something like from_str("2"):

code:

#![feature(zero_one)]

use std::ops::{Add, Rem};
use std::num::{One, Zero};

#[derive(Debug,Copy,Clone,Eq,PartialEq)]
enum Parity {
    Even,
    Odd,
}

fn parity<T: One+Zero+Add<T, Output=T>+Rem<T, Output=T>+PartialEq>(n: T) -> Parity {
    let zero: T = Zero::zero();
    let two: T = <T as One>::one() + <T as One>::one();
    if n % two == zero {
        Parity::Even
    } else {
        Parity::Odd
    }
}

fn is_even<T: One+Zero+Add<T, Output=T>+Rem<T, Output=T>+PartialEq>(n: T) -> bool {
    parity(n) == Parity::Even
}

fn main() {
    println!("{}", is_even(42_f64));
}

Even that requires the nightly branch instead of stable. They used to have more traits for writing code generic over numeric types but I think they didn't want to commit to them for 1.0 so they all got yanked a while back.

Update: this may be out of date, but it may be impossible to use constants in generics right now. (Luckily, for this specific use case there's an is_even method in the num::integer::Integer trait, but no multiplying arbitrary numbers by 5).

Julia's pretty cool, but I had a hell of a time developing anything with command line or file input in it. Juno is not built for that, which is a shame because it has so many nice features. I also had this annoying problem where Juno and Julia's packages were not in sync (stored in different places), so it would've taken a lot of package installing to switch to the command line version. I literally ended up hard coding absolute file paths.

To be fair, this isn't at all Julia's fault so much as a mix of Juno and Atom's.

Atom is super annoying in general because it gives you no installation options or configuration. If your main drive is a small SSD, there is literally no way to inform Atom (or anything derived from it) to kindly install to another drive. Just double click the installer and it pops up a beautiful splash screen designed by some wonderful graphic design guy and proceeds to autoinstall wherever the hell it feels like it. It's so "simple" and "elegant". And "horrible".
