Sorry guys but CNN have officially revealed that ironic "first for _" posting in /dpt/ is no longer funny

C++ is a meme

What has damaged programming the most out of all the OOP languages?
Smalltalk, Java, ...?

friendly reminder that category theory and """purity""" are not silver bullets against shitty software

do not worship these false gods

>>56044442
C++, it was the first mainstream one

OOP has set programming back by decades

>>56044452
agreed. They are mathematical tools, not magic spells.

>>56044452
Patronizing reminder that types prove universal properties about code, whereas tests only prove existential properties.

OOP encourages shared state.
I don't know how any retard could possibly argue FOR shared state.

>>56044519
I didn't say types obviate the need for tests.

>>56044527
>OOP encourages shared state.
the complete opposite you fucking retard, it encourages encapsulation of state

>>56044547
And then you pass that state around and encourage mutation of it. A recipe for disaster.

drop your codeforces handle

>>56044537
types don't do anything put prevent the most basic retard-tier errors and enable autists to sit around and jerk off all day

>>56044547
Encapsulating state doesn't stop it from being shared.
Whenever you call a method on an object, you are indirectly modifying their state. If two or more objects modify the state of another object, there is shared state.
Encapsulating state like that is fundamentally flawed.
The better solution to is minimise the amount of state you have in the first place.

KILL YOURSELF YOU ARE FUCKING RETARDED AND I'M NOT GOING TO WASTE MY TIME ON YOU, JUST SAYING YOU'RE A PATHETIC IDIOT

>>56044567
>>56044601
(You) clearly don't know anything.

>>56044589
If you're using Java's type system, maybe.

Even Haskell's type system is quite limited.

>>56044597
nice gobbledygook idiot

>>56044597
Why do you need an initial a?

Are Haskell programmers TOO smart to be employed?

>>56044589
They also enable better tooling in general, eg. autocompletion and refactoring, which is desirable when you're working on large codebases that actually do things.

>>56044646
a is a parameter that's a type

it's the same as
sort :: forall a. array a -> { x : array a | isSorted x }

>>56044678
I dunno, but the first thing I do on any project is implement a Haskell interpreter

>>56044701
I see, the previous notation was ambiguous to me

Don't you need an Ord instance for it, though?

>>56044701
Define isSorted formally: I'm genuinely curious

>>56044786
isSorted (x:y:xs) = (x >= y) && (isSorted (y:ys))
isSorted _ = True

>>56044808
*y:xs
this is descending order, would want <= for ascending, that would make more sense

>>56044808
Yeah nice, nice

>>56044731
well it's not haskell it's some ambiguous dependently typed language, it might not even have type classes

maybe something like

sort :: (a : ord) -> array a -> { x : array a | isSorted x }

>>56044684
>which is desirable when you're working on large codebases that actually do things.
oh so nothing haskell is used in.

I need a project. Something impressive and something that will take my skills from mediocre at best to where they should be as a senior software engineering student.

The most complicated piece of software I ever wrote was a simple calculator, just to give an indication of how shit my skills are. I'm OK in both C and Java and that is about it.

I love lua. That's where I started my programming career was making WoW addons lol. What ya doing with lua?

>>56044987
My problem is for years now I've neglected to do much of anything during my breaks / outside of class. most always tend to start something, but then give up at the first sign of difficulty / confusion.

I made a calculator for one of my classes in my sophomore year. Other projects have been: multi-threaded scheduler, shell emulator in operating systems, "aliens vs humans", a simple game, in my design patterns class, implementations of sorting algorithms in my algorithms class

...and that's about it. I still have an entire year left of 400 level courses, so hopefully I'll get to work on something truly interesting / challenging

When you start using neat tools like Greenshot along with ahk it's pretty awesome.
Effectively region of the screen capture.

And it's like 2 mouse positions and 2 clicks/presses.

How do i learn to make code go fast?
Beginners guide to optimizing something basically. Assume algorithmic optimization is done of course.

>>56045199
go read book on algorithms and datastructures first, then stop coding performance code in python

>>56044934
>impressive
For non- programmers?
Write a GUI interface for a neat CLI tool. Something like youtube-dl and https://libav.org/.

I recommend using C and imgui. It's really neat. And it allows you to focus on the things that people often lack. Things like exporting a youtube clip to a nicely sized gif/webm file.

It shouldn't be too hard. But if you ever struggle with libav you can just use ffmpeg and call that instead.

>>56045221
>go read book on algorithms and datastructures first
Yeah I already have. What kind of fucking suggestion is this though? I told you algorithmic optimization is already done.

Are you basically saying 'I don't know'? Because it sounds like it.

>>56045159
yeah, pretty much. I really don't deserve to have gotten as far as I've gotten. I've got a plethora of mental issues on top of being just truly mediocre and I can't ever imagine being an actual software developer. I browse /dpt/ all the time, and wonder if I could join in more often, had I applied myself, had I dealt with my borderline autism / crippling depression years ago before entering the program. or maybe I was doomed from the start, and I've always been destined to stock shelves.

sad thing is, I'm actually mid-range in my department. I know plenty of dudes in way worse shape than me. I remember last semester a senior had no idea what a regular expression was, hadn't even heard of the concept. This same guy could barely use a terminal and had no idea how to write a makefile. There was this other guy I was paired with in OS class, and he was a senior at the time. I remember writing 99% of the code for our various weekly labs because he struggled with even basic shit like switch statements and pointers in C.

                printf("\t");
                if (number % 15 == 0){
                        printf("printf(\"fizzbuzz\");\n");
                }
                else if (number % 3 == 0) {
                        printf("printf(\"fizz\");\n");
                }
                else if (number % 5 == 0) {
                        printf("printf(\"buzz\");\n");
                }
                if (number % 3 && number % 5 != 0) {
                        printf("printf(\"%d\");\n", number);
                }
        }
        printf("}\n");

There, a shittier code to make a shitty fizzbuzz.
How would you worsen the fizzbuzz inside the program even more without overcomplicating it?

kind of true I guess. A lot of students learn about them and think that they have to design software systems by putting together different patterns like a puzzle. they're not meant to be spammed left an d right in software design; not meant to be used in that way. I think they're meant to evolve naturally as you build the system.

Also, they are used to communicate with other developers more easily.

Most of the students with nearly perfect grades from local community colleges fail out of their first year of the university I attended.

There are massive differences in syntax among DBMS's, as well as difference ODBC drivers required to interface with them.

That's why you model the data within the application and abstract out methods that can send the same concept to different database tools.

Not really.

Community colleges are generally for shorter two-year degrees, while universities are for those pursuing a more involved field.

That being said, many people who don't get accepted in the university of their choice use a local community college as a stepping stone to try to prove that they can make good grades outside of high-school. Some universities even have arrangements with specific community colleges to choose from their students, and in return, they help guide the curriculum of basic disciplines (basic math, science, literature, etc.).

>Rust is what Go should've been
Are you fucking retarded? Rust and Go are completely different down to their prime principle. Rust follows the C++ creed of zero cost abstraction. It favours decrease in complexity only if it has zero or near zero impact on performance. This results in a more complex language to facilitate this lower level of abstraction. Still less complex than C++ of course. Go on the other hand purposefully simplifies the language at the cost of a higher level of abstraction and lesser performance. Essentially it can be viewed as a middle ground between C and Python/Java/etc. Apples and oranges, retard.

If you're an "animal cracker" programmer, then you have no security.

You're serving the purpose of making working, efficient, optimized, safe, error-proof, module-able, adaptable and readable code.
That is the work of a programmer, which Pajeet can't do half as well.
If you're involved in business decisions you're not a better programmer for it, you're just higher up in the food chain, of course you'd have more job security but that doesn't make the actual programmers dispensable.

Hey guys, I just started learning Python (on Udacity) a couple days ago.

I've got (very) basic C / C++ experience, and the indentation bullshit on Python is turning me off tbqh.

Should I just learn Java instead?

>>56047789
C#, IMO.

It's honestly the best of both worlds with respect to Java and Python.

>>56047787
it's gotta be three unfortunately. I was thinking top and bot but that's not quite right. I wanted to try extending saturn a little since I noticed it was lacking in ways to pull things out of a string. My example program that uses the two instructions I'm implementing:

;reverse a string
main:
    str string
    int slen
    out stdout, 'Please enter a string: '
    get string, stdin

chk_zero:
    len slen, string
    cmp slen, 0
    jne out
    ext 0

out:
    str s, string
    tail s, 1         ;need better mnemonic
                      ;is tail even necessary? head with negative arg?
    out stdout, s
    dec slen
    head string, slen ;need better mnemonic
    jmp chk_zero

It works with any length instruction name because of how the parsing works, it's just that every other instruction in the language is 3 letters long.

Don't do this if you're targeting Linux, unless you're fine with second-class language support. Java is unequivocally superior cross-platform, but C# has some niceties that Java is conspicuously missing. They're very similar (C# was borne of MS's efforts to EEE Java), so learning either will help with the other.

>Java > C# > Ruby > Python
no
/dpt/ is not a good place for advice
python and ruby are decent for scripts, cli applications, high level backend dev and decent if you want to start out with a high level language (you should switch to something else once you can handle basic CLI applications and stuff like control flow and functions, though).
mit and many other unis start with python, but quickly transition to other languages.
c# and java are very similar. c# is mostly limited to windows at this point. c#'s strength is backend webdev and windows desktop applications, java's strength is backend webdev and android dev.
many unis transition to c# or java after python for oop fundamentals, many also start with c#/java directly, although there's more "noise" that you might not understand at the start than in python
a low level start or a functional start isn't unthinkable either.
C / assembly -> C++ for a low level start, lisp/haskell for a functional start (lisp especially if you wanna get into ai)

Rather go for scala since it has better syntax + fp and great java interop

Assuming you already know how to pull in data from the SQLite database, you'd take that data and populate a list of strings or objects containing multiple properties.

Just assign the combobox's ItemSource property to that list:

cboListOfThings.ItemsSource = new List<string>() { "anal beads", "dragon dildo", "fuzzy cuffs" };

If you're expecting the combobox to automatically update based on the underlying data, you need to look up "data binding".

>>56048290

Yes. In fact, its was rolling for a solid 15 years before it ran me over.

I'm literally stuck inside.

Kill me, please.

>populate a list of strings
Makes sense. This list specifically isn't going to change much so this seems like the way to go.

>If you're expecting the combobox to automatically update based on the underlying data, you need to look up "data binding".
Yeah, I've been reading about data binding; it's kinda dense reading-wise on MSDN but that wpf-tutorial.com site feels a little too general. Is data binding the "quick and dirty" way?

We're dealing with the same, with the added bonus of also maintaining the legacy Java code it interacts with.

Eh, not really that bad.

Mostly management - Every attempt to refactor any part of the project requires an act of congress to approve.

Also, management likes to 'help' sometimes. At least I get a fresh batch of bugs to distract me whenever they do...

>>56048415
No, data binding is the "proper" way, actually, as is using full MVVM patterns.

The way I showed you isn't "wrong", but it's static in nature which has its downfalls (data doesn't automatically match the underlying objects if they change).

This means that the state of the data object and the state of the GUI element is independent.

I see singletons. Singletons everywhere. Singletons for timers, filesystem managers, and stupid stdio wrappers.

> they want to make it thread-safe

>>56048483
Singletons are love, singletons are life!
Memory eficient, thread safe, management loves them, they are the best for every situation!
