I've heard people talk about thinking in a programming language.

Is this hyperbolic, meaning simply having a mastery of a language so it's rules are intuitive to you or does the Sapir–Whorf hypothesis possibly apply to programming languages as well?

>>58770852
>does the Sapir–Whorf hypothesis possibly apply to programming languages as well
Yes, of course it does, it's probably the easiest place to see it in action. Someone used to using an OO language will want to use objects for everything, someone used to using a Lisp will want to use macros everywhere, etc.

>>58770852
The brain optimizes out the translation layer at some point.

>>58770876
This, and someone using FP will create software that works.

>>58770852
Well, only mastering a limited number of languages probably affects how you approach problems; Since you spend a lot of your time thinking in terms of the semantics of a language, you will come up with solutions to problems under those semantics as well.
For instance, if a problem requires traverse some sort of structure and you write a lot of C, you'll probably be drawn to for loops, while someone who writes a lot of FP will probably reailze the appropriate fold that would accomplish the task.
It's important when learning multiple languages to realize the equivalencies between the constructs presented in both, and to make sure that you are considering the constructs of both rather than just trying to rephrase constructs from language X into language Y.
FOr instance a new lisper may be tempted to use flags and conditions when it may be a better solution to use higher order functions. But a lisper going to C may try to use recursion and function pointers where it is inappropriate because of C's poor support for the constructs from lisp that is attempting to be emulated.

>>58770852
>>58770876
I should specify that it's more like that person is ONLY used to using certain types of language. The more different languages you know, the less you will be affected.

In my university we learn Java in a strange way but it presents us with the equivalence between FP and OOP.
For instance the following haskell code:

data NamedColor = Red | Blue | Green
data RGBColor = RGB Float Float Float

toRGB :: NamedColor -> RGBColor
toRGB Red = RGB 255 0 0
toRGB Green = RGB 0 255 0
toRGB Blue = RGB 0 255 0

Is the same as the following Java code:

class RGB {
  float r, g, b;
  RGB(float r, float g, float b) {
    this.r = r;
    this.g = g;
    this.b = b;
  }
}

interface INamedColor {
  RGB toRGB();
}

class Red implements INamedColor {
  public RGB toRGB() {
    return new RGB(255, 0, 0);
  }
}

class Green implements INamedColor {
  public RGB toRGB() {
    return new RGB(0, 255, 0);
  }
}

class Blue implements INamedColor {
  public RGB toRGB() {
    return new RG(0, 0, 255);
  }
}

This is of course known the value problem, and while the Java code is obviously more verbose, it does have it's advantages (if you were to add more colors).

>>58770941
This just isn't correct.

How anyone can claim that Go development isn't fast just shows that you don't know what you're talking about.

What language should I learn next?

>Scheme

Scheme is a meme language. This is my conclusion after taking the EdX Systematic Program Design course from UBC.

The reason is, we spend all kinds of time commenting and templating about what types of data the program should use, but it's all comments that don't do anything.

Trying the same thing in a language with a proper type system would make all the comments redundant and make the programs safer.

I'm going to finish the course, but I'm learning Haskell or OCaml straight after.

>>58771121

It's meant to be a teaching language. You don't have to specify design recipe bullshit in real programs. They teach this way so that it makes more sense when you are introduced to statically typed languages. And so that you understand that the purpose of types are documentation and verification (not just appeasing the compiler gods, like the poor kids in the intro Java course struggling with the garbage type system).
Python babbies don't even understand the merits to good type systems; they prefer to have special language syntax that are essentially comments ("annotations" gege).

I've been writing a lot of Racket lately and I always include a one line comment and a type signature comment above my functions just so I remember the argument order / return type without having to delve back into the implementation. However I spend the majority of my time writing code or coming up with algorithsm.

I agree with "documentation and verification". However, a type signature comment does not provide any verification.

>Python babbies don't even understand the merits to good type systems; they prefer to have special language syntax that are essentially comments ("annotations" gege).

There are a lot of reasons for a Racket hacker to legitimately snob out against Python, but I don't think types is one of them.

>I've been writing a lot of Racket lately and I always include a one line comment and a type signature comment above my functions just so I remember the argument order / return type without having to delve back into the implementation.

You are a beginner and we would prefer you not have to fight with the verification tools just yet.

Fair enough.

>Cool that you're doing productive work in Racket. I can definitely see, after using it for a few weeks, what a good dev environment it is.
I really enjoy it. But I'm mainly doing PL stuff, which is kind of what Racket is pushing to be good at anyways.
I also used it to generate plots for a physics lab report, which was very neat and easy to use.

>>58771361

Look at Racket's contracts. Many scheme implementations support something similar.

>Trying the same thing in a language with a proper type system would make all the comments redundant and make the programs safer.
But this has drawbacks: runtime type information is powerful, and allows one to reuse components in rich ways. Often times, we are working with incomplete and evolving data. Static typing doesn't model this reality particularly well, except for contrived examples in relatively well-defined problem domains. Rather than focus all of your time defining types, Lisp puts an emphasis on defining operations to work over generic data.

Common Lisp has a very impressive type system, and Clojure's new spec system is really game-changing.

Of course Scheme doesn't have standard support for these things -- it was designed by programming language theorists to be flexible enough to try out new ideas quickly.

Saying
>Scheme is a meme language

>Static typing doesn't model this reality particularly well
I'd say many of Haskell's libraries are great examples of static typing done right. Things like functors and monads crop up everywhere. They're fantastically generic and reusable.

Come on..

>>58773318
Right, but when you are dealing with evolving data models, incomplete data, etc. Haskell's type system __tends__ to get in the way. It solves the problem fine when it is well-defined, but as an application is forced to evolve, it certainly becomes possible to paint yourself into a corner with the type system. Hence, it is possible to make elegant, generic, and reusable code in Haskell for generic, well-defined problems, but as the problems evolve in their complexity (and I'm speaking more of the reality of software engineering in a large environment, not how difficult an algorithm is to implement), it becomes less well-suited compared to other options.

It's no C but it's a good in-between

Why does no one talk about C# here? I'm currently taking online tutorials on it but i'm wondering if there's an easier language to start with? Is C/C++ a better choice? Any advice would be great.

>>58774037
C# is better than C++ but it's also more OOP so you want to try to avoid that

>>58774037

C# is occasionally posted here, particularly when OSGTP is around. C is the easiest language to start with, C++ commands a bit more of the programmer to actually understand the nuances of the language to make effective use of it.

don't get me wrong, i've come a long fucking way. last august i didn't even know what a REST API was, now i'm designing fully-featured, dynamic web applications for the startup from scratch. in the span of 6 months, i've gone from doing data entry into the database, to a developer role. i've learned a fuckton, but when it comes to moving on from this company, i won't fare well in the interview process because i don't have a formal education in algorithms and data structures and shit. everything i know now i learned by breaking shit, figuring out what broke, then fixing it.

and fuck the idea of getting into any top company like fb/amazon/goog/palantir. fuck the idea of getting a 6 figure salary. i don't think that will ever happen in the next 10 years.

>>58774192
I sympathize, anon. Tech hiring is really broken.

The only time I've ever needed to implement an algorithm I learned in college has been in my hobby projects, where I'm deliberately writing lots of things from scratch. Implementing binary search or whatever has never come up in my day job.

I think part of it is that it's really difficult to test well good someone is likely to perform on real problems in a one hour interview slot. The interview would be over before you finished explaining all the necessary context. So you end up with really artificial problems and/or algorithms quizzes.

>>58774229
i really don't care that the hiring process is broken or whatever, i just think i started preparing way too fucking late. i graduated with a degree in applied mathematics last year, when i could have been doing something useful like a cs degree that would have at least prepared me a little bit with courses on algorithms/data structures.

I hate javascript as much as the next guy but please don't criticize it on a basis that is true for every other language; it just nullifies your argument.

Actual bad things about javascript:
> weakly typed == and operators other than + (arguably weak + is bad too, but many languages allow it)
> 'this' argument, which has to do with prototypes and was built because they didn't think closures would be as popular
> adding new slightly-different syntax ("""arrow functions""") usually doesn't actually fix the language, as evident by e.g. C++
> variable hoisting, which is a lazy way to fix mutually recursive functions. again fixed by "patching" new features.
> prototyping isn't useful and hardly any javascript code takes real advantage of it
> object key iteration is fucked because of prototyping, and you have to be very careful and use things like Object.keys to avoid bad things
> object keys being coerced as strings is arguably bad; they """fixed""" this with weird Symbol shit
> other minor inconsistencies and dumb shit, like .map pointlessly applying extra arguments and .sort sorting numbers alphabetically, or the parser interpreting the function keyword differently if its an expression or a statement

Note that you could create lists like these for most shitty blub languages.

Programming is a terrible profession. For one, you are not respected at any normal company. You're known as 'IT' or 'tech' and everyone gossips about how disgusting everyone is in the department. Every day, some Alpha who probably does nothing at his job except get his secretary to suck his dick in his corner office cucks you into doing random bitch work, and then yells at you when it's not done by the deadline despite it being impossible to complete the work requested. Not only that, the code rarely works, your co-workers are smelly Indians brought in by Tata Consultancy and connive to replace your job at all times for half the salary, and the work never, ever ends. You pollute your body with sugar and toxins, deprive it of sleep, and let it rot while you sit the majority of the day, neglecting any healthy exercise, social interaction or life goal attainment. It's like a Postal worker, but coupled with feelings of patheticness, lonliness, helplessness, rage and total hopelessness.

Women, when they hear you are a programmer, instantly remove you from the potential pool of mates as they know your earning potential is maxed early and your career over at 35. They are also instantly disgusted by you. It is far better to tell a woman you are on welfare than to out yourself as a computer programmer. It's also highly embarrassing for a woman to date or be married to a programmer, as virtually everyone knows they are the grown up version of the hopeless virgin in high school. One who never really grew up and became normal and fit into society, but rather found an environment where he could escape the reality of his situation and be invisible, able to hide the toxic shame and utter humiliation that is the programmer.

>Exercise 1.8. Newton's method for cube roots is based on the fact that if y is an approximation to the cube root of x, then a better approximation is given by the value

Use this formula to implement a cube-root procedure analogous to the square-root procedure. (In section 1.3.4 we will see how to implement Newton's method in general as an abstraction of these square-root and cube-root procedures.)

Python is very easy to learn, but if you want to go all in and learn the least high-level high-level language, go with C

Also, steer clear of object oriented programming if you're only beginning to learn.

Your conclusion is not well drawn.

However, what you've hit on is a good reason to prefer static over dynamic typing. That said, dynamic typing does have some advantages.
