Is python a good first language?

>>57084481
Yes.

>>57084481
No.

>>57084481
yes. Just make the mistake of thinking it's a good langugae in general.

it makes me sad to see that so many of you waste your talents with being NEETs. i have the impression that some of you are really fucking talented but instead all you do is piss in bottles and jack off to lolis

Supposedly Python is easier for first time programmers to learn, but you'll end up abandoning it when you realize it sucks and wish you had put that time into learning a real language.

>>57084505
Sort of: my own 16-year long experience in writing Python code for various tasks.

Compared to most other languages, Python is fine for beginners. If nothing else, it beats Java in everything. Java is fine for certain tasks, but not for beginners. Java rots their mind, like BASIC did back in the day.

>>57084587
>it beats Java in everything
Java is much faster
Java is much better for large codebases simply by virtue of the fact it is statically typed.

Java isn't even a good langugae in comparison to other langugaes you could be using.

>>57084596
>python ruins you for life
>python rots your mind

if you don't know what you are doing

>>57084481
Just learn C. It's the only language you need.

At least we can all agree that Haskell is unironically an excellent first choice of language

>>57084624
no, it's the last choice of language

all languages come before it

>>57084481
i personally think it is
it is really fun to write some cool scripts and shit like that to automate boring tasks

i'm new to python but it has helped me a lot

>>57084631

Hey,

I'm doing the a/A jumpstart program. Has anyone applied to app academy? if not, what's your thoughts on the program? I'm trying to make the jump from my STEM degree and shift into programming. I don't feel like going back to school to get a masters in bioinformatics just to get an understanding of programming. So far, I'm in a week in and I feel like the culture of the program isn;t all that welcoming for newbie who are trying to make the shift into programming.

Yes, that's the problem. I can write fast code in C, and I can write code fast in python. Never had the need to use haskell for something.
I wanted to use it for prototyping but I find slow to iterate between write-compile loop.

just bored and thought id try to play with some js my questions are

1)I figure I need a submit button on the html?

2) and I need to call the function after defining it?

3) should I just take the inputs with JS and leave out the HTML, what do people usually do? (although I kinda like learning the HTML with the JS, dont think id bother learning it on its own lol)

4) are those alerts written right, i just tried to write it like python's print

    <!DOCTYPE HTML>
    <html>
    <body>
        <p>Please Enter A Temperature</p>
        <input id="temp" type="number">

As of yet, no. There was an issue with juno's product. Also, I understand why you have that kind of mentality, but would you rather deal with the side effects or live with a crippling disease? The only true evil with pharm companies is how they treat their workers and the readiness to shift to a new product or cut ties and sell the name of the drug while fucking with their workers who got them there.

If this is Main.java

public class Main {
    public static void main(String [] args) {
        for (int i = 0; i < args.length; i++) {
            System.out.println(args[i]);
        }
    }
}

And you compile it and run it from your terminal

javac Main.java
java Main hello world blah blah

It will print "hello world blah blah" with each word on its own line, because each word is an argument in the args array (a "token").

When a type theorist is asked what Haskell is good for, he says type theory. And then he'll be hard pressed to come up with anything else. At least those on /dpt/.

When a systems programmer is asked what C++ is good for, he'll name many concrete applications that don't feed back into systems programming. Such as browsers, kernels, etc.

Haskell is mastubatory because it's a closed cycle with no output.

>>57086395
Haskell is useful for literally everything except systems development and high-performance applications

Just say you know nothing about Haskell and have never used and be done with it already. You're only embarrassing yourself.

So I have a .obj file reader I wrote for my openGL project

It reads the text file and stores the vertices as a "vertex" type, which is just 3 floats with x y and z

I realized that it is probably I good idea to switch this to using GLM types because that's what OpenGL will use. Should I store 3d coords as vec3s in an array? maybe some type of matrix? or perhaps as vec4s with a zero w component?

>>57086432

a) mumble something about type theory

Making a shit c# program for a uni project, using WPF, I need the user to be able to select multiple items (seats for a play).

I'm thinking the best way to implement it would be with a listbox, but if I understand correctly, the user would have to use shift click to select multiple items, which isn't the easiest for new users to know, unless I label it I guess.

Is there any other better way? I found a tutorial on a checkbox combobox by some pajeet which was like 500 lines of code kek

Calling all Pajeets / Enterprise bros / Java professionals...

I'm creating my own data mapping layer. I'm NOT using any frameworks such as Hibernate, etc... or ORMs / other abstractions.

My problem is I have a bidirectional many to many relationship in my domain model. Loading into memory seems simple enough - load the object, then load all of it's corresponding objects (while checking that they're not already in memory). The brain twister comes when I am inserting an object...obviously I'll want to also insert all of it's corresponding objects...which will then try to insert all of it's corresponding objects...and so on...

How do I structure this in a nice way? Could I keep track of what has already been inserted? Would a "unit of work" help out here?

Again, inb4 "use hibernate bro", I'm doing this all by hand.

>But Haskell has already been deprecated by the next FP meme language which even the Haskell people admit is better at FP than Haskell: Idris.
that's bullshit though
GHC has a ton of features Idris doesn't
Idris is supposed to be performant but has less optimisations than GHC

>>57086801
Users of real time haskell will be shocked. Shocked.

>>57086791
But why not use JPA/Hibernate?
In those frameworks there is a concept of a proxy.
Each object you get from a database is actually a dynamically created subclass of your object, and they use the mechanism of so called lazy fetching, other objects are fetched from the database only when you want to use them.
So basically when you get Person object from the database, then the Address object contained in it is not actually there, until you use it.

>>57086729
I want do something like, "variablename value" as input and then change the variable to that given value.
I need to do this as i cant hardcode the values and the python script will only run as subprocess controlled by another program.
Exec seems to be pretty close to what i am looking for.

>>57086770
I'm currently spread over a few things at the moment, the book "The Little Schemer" is supposed to be good but its format is quite confusing to me.

I'm not sure how lazy loading with virtual proxies would solve my problem here. That's definitely something I would like to implement in the near future tho.

but for now, I would like some way to keep track of what has been inserted already, so I don't get locked into some sort of cycle between the dependencies.

currently my saves look like :

protected void save(DomainObject obj) {
    // update row with specific domain object state
   // call save method for all objects in it's list of objects that it is related with
  // map relationship to association table
}

If this was for a job, or a personal application, I would definitely learn Hibernate / JPA / whatever. But this is for a college course on building enterprise systems. There's no way in hell any hand rolled solution would even be 1/1000th as good as what goes on underneath the abstraction of a framework like Hibernate, but I need something that works for a small system, and is sufficient clean and not overly complicated and messy.

Between dogs and cats my degree of choice is so great that it would never occur to me to compare the two. I have no active dislike for dogs, any more than I have for monkeys, human beings, negroes, cows, sheep, or pterodactyls; but for the cat I have entertained a particular respect and affection ever since the earliest days of my infancy. In its flawless grace and superior self-sufficiency I have seen a symbol of the perfect beauty and bland impersonality of the universe itself, objectively considered; and in its air of silent mystery there resides for me all the wonder and fascination of the unknown. The dog appeals to cheap and facile emotions; the cat to the deepest founts of imagination and cosmic perception in the human mind. It is no accident that the contemplative Egyptians, together with such later poetic spirits as Poe, Gautier, Baudelaire, and Swinburne, were all sincere worshippers of the supple grimalkin.

Naturally, one’s preference in the matter of cats and dogs depends wholly upon one’s temperament and point of view. The dog would appear to me to be the favourite of superficial, sentimental, emotional, and democratic people—people who feel rather than think, who attach importance to mankind and the popular conventional emotions of the simple, and who find their greatest consolation in the fawning and dependent attachments of a gregarious society. Such people live in a limited world of imagination; accepting uncritically the values of common folklore, and always preferring to have their naive beliefs, feelings, and prejudices tickled, rather than to enjoy a purely aesthetic and philosophic pleasure arising from discrimination, contemplation, and the recognition of austere absolute beauty. This is not to say that the cheaper emotions do not also reside in the average cat-lover’s love of cats, but merely to point out that in ailurophily there exists a basis of true aestheticism which kynophily does not possess.

>>57087360
The real lover of cats is one who demands a clearer adjustment to the universe than ordinary household platitudes provide; one who refuses to swallow the sentimental notion that all good people love dogs, children, and horses while all bad people dislike and are disliked by such. He is unwilling to set up himself and his cruder feelings as a measure of universal values, or to allow shallow ethical notions to warp his judgment. In a word, he had rather admire and respect than effuse and dote; and does not fall into the fallacy that pointless sociability and friendliness, or slavering devotion and obedience, constitute anything intrinsically admirable or exalted. Dog-lovers base their whole case on these commonplace, servile, and plebeian qualities, and amusingly judge the intelligence of a pet by its degree of conformity to their own wishes. Catlovers escape this delusion, repudiate the idea that cringing subservience and sidling companionship to man are supreme merits, and stand free to worship aristocratic independence, self-respect, and individual personality joined to extreme grace and beauty as typified by the cool, lithe, cynical, and unconquered lord of the housetops.

>>57087372
Persons of commonplace ideas—unimaginative worthy burghers who are satisfied with the daily round of things and who subscribe to the popular credo of sentimental values—will always be dog-lovers. To them nothing will ever be more important than themselves and their own more primitive feelings, and they will never cease to esteem and glorify the fellow-animal who best typifies these. Such persons are submerged in the vortex of Oriental idealism and abasement which ruined classic civilisation in the Dark Ages, and live in a bleak world of abstract sentimental values wherein the mawkish illusions of meekness, devotion, gentleness, brotherhood, and whining humility are magnified into supreme virtues, and a whole false ethic and philosophy erected on the timid reactions of the flexor system of muscles. This heritage, ironically foisted on us when Roman politics raised the faith of a whipped and broken people to supremacy in the later empire, has naturally kept a strong hold over the weak and the sentimentally thoughtless; and perhaps reached its culmination in the insipid nineteenth century, when people were wont to praise dogs “because they are so human” (as if humanity were any valid standard of merit!), and honest Edwin Landseer painted hundreds of smug Fidoes and Carlos and Rovers with all the anthropoid triviality, pettiness, and “cuteness” of eminent Victorians.
