I'm having some trouble with reflection in C#.
Say I have a whole bunch of classes where every method inside them is private except for one, and all are argless with the same title.
The easiest solution would be to make them all derive from a base abstract class and then use reflection to call the override methods in each one. But I'm stuck at telling it which one specifically to call.
Is there some way to utilize reflection to determine derived class names so I can just parse out the one I want based on input?

Here we go, actual b8. Assembly is the king of languages, he can only control his kingdom and does it uniquely to all the other kingdoms. C is the guy who said, "fucking hell why are all these similar kingdoms being ruled differently but essentially work the same?"
C brought together all the kingdoms and established universal rules of law to follow. Now what's bad about that?
>>54138028
do you write unit tests?

>C brought together all the kingdoms and established universal rules of law to follow. Now what's bad about that?
it wasn't good enough. thankfully c++ saved us

I don't. They are way too much of an hassle for what they do. We also use tests that actually opens application and do larger tests and I think that is enough.

C was made in the 70's and hasn't evolved since then. even at that time it was considered to be a shitty PL. The people who acclaim C are PLT illiterate.

/dpt/ joke of the day:
why do programmers only drink canned beer?
i want to make a script that scrapes a website and returns a rss-format file
is there a better way to do this?
>>54137816
Okay so I've got it where I can pull in the derived classes and get info about them
I cannot, however, run the override method in question.var methods = Assembly.GetExecutingAssembly().GetTypes().Where(t => typeof(Problem).IsAssignableFrom(t)
&& t != typeof(Problem)).ToArray();
Console.WriteLine("Please enter the problem number you wish to run");
var input = Console.ReadLine();
var method = methods.Where(t => t.Name == "Problem_" + input).First().GetMethod("Run");
object o = Activator.CreateInstance(method.ReflectedType);
this will create me an instance of the object I asked for, but it's only displaying some private static variables I defined within the class itself. I don't see any methods.

You're the entire fucking reason every codebase I've had to work with at every job is an unintelligible mess riddled with regression bugs.

non sense. it's not about fixing things but about new technology.
>>54138372

>>54138352
I'm specifically referring to UI tests, where mouse clicks are done on specific elements by an automated agent. I've had terrible experience with those kind of tests.
>>54138283
air through nose/10
>>54138461
Because you've probably never had to specifically work at that 8 hours a day. Blackbox and UI testing is certainly incredibly fragile, but if your test engineers wrote everything smartly (namely using a page-object-model for easy maintenance) then the exact same goes for it.
Short of complete and total UI overhauls, those test bases should remain usable and valid for a long time. They require closer inspection on failure and also require very strict success thresholds, but that's why "Test Engineer" is it's own, separate job.
That being said I've worked those jobs too, and the asshole who skip unit tests, even just here or there for one tiny thing, made my life a living fucking hell because the blackbox testing would intermittently fail shit and it takes god damn eons to determine whether it's the test code fucking up or if it's some dipshits undocumented red code bugging up

>>54138372
You are wrong. Tearing down a computer, it still works with bits and bytes. The fundamentals don't change, so why should a language that works so closely with the fundamentals change?

There's nothing wrong with pointer arithmetic or any of the things found in C (or any programming language) from a theoretical perspective. You could even use lambda calculus and/or set theory (or whatever your favorite formalism is) to describe C if you wanted to.
A programming language is just a formal system. Parts can be nondeterministic or undefined. There's nothing wrong with that.
If a language was wrong in a theoretical sense, it wouldn't be able to exist. We wouldn't even be able to describe or talk about it.

Is C/C++/python a good combination?
Is C worth learning today compared to learning C#/C++? It seems like most jobs in my city are looking for people to work in C# and everything webdev
>>54138885
>learning python first
oh man I hope you don't hold on to those fundamentals. START LEARNING C++ NOW. Yes right now. Like, read this right now http://www.learncpp.com/
>>54138885
C++ and Python are definitely a potent combination.
C is a very niche language and has been practically superseded by C++. There are very few areas where C is useful. That said, if you are a student I would recommend learning it. It will teach you a lot, even if you don't end up using it in production.
>>54138942
It will teach you a lot, but learning C might encourage bad habits when getting to write C++. Learning C++11 first will give you a taste of actual programming. Going to C make the two language seem separable. That's important... imo

Don't worry. I learned 2.7 about six months ago then I've forgotten pretty much most of it.

>>54138942
That's what I was thinking. Ideally jobs don't interest me as much as research positions so I'm thinking doing C just to wrap my head around a bit of history that could lead into a better understanding of other languages would help unless I'm just wrong in thinking like this.
>>54138984

drop PROCEDURE peopleInCompany
GO
CREATE PROCEDURE peopleInCompany AS
SELECT * FROM person As p
WHERE EXISTS (select * from workplace as w where w.cpr = p.cpr)
EXEC peopleInCompany
Any clues to why the procedure shits itself?
>>54139186
Learning order doesn't have an accepted standard, although I strongly recommend if you want to develop programs (careful wording) you should learn C++ first. It will help you develop programming intuition and will be a platform for you to be able to learn new languages more seamlessly. After experience with C++, go to C if you want to interact with more low level elements. At that point, it's not as much about developing programs as it is about having the fastest code (careful wording) on the block. Decide for yourself, but in either case, I would still recommend learning c++ first. Keyword is, "I".

This is computers we are talking about. The rules stay the same, the universalization expressed with slight abstractions. Creativity comes from an operator's ability to manipulate these rules.

you can make a pointer variable, call new (or even malloc if you wanted to) and get a pointer back into the heap and manipulate the pointer, do address arithmetic etc

>>54138071
>>54139487
A lot of 70s graphical workstations and capability-based architectures wouldn't be able to run C. Many of them were built around the notion of making language-level objects available system-wide.
For example, instead of a text file, you would have a text object, which is like a string with some metadata. On a lower level, you would just be reading from pointers and the virtual memory would handle everything. The Classic Mac resource manager was inspired by one of these systems.
This is a big difference from the "disk operating system" model used by Unix and Windows.
This kind of technology might show up again in the future. It would be a pretty good fit for the various features provided by HTML5.
>>54139690int** x; //pointer to a pointer of ints
it's a common way of implementing C-style matrices, it's a real fucking pain to manage though and should be avoided.

x[0] = new int[3];
x[1] = new int[3];
...
now you have to remember to delete all the inside arrays, then delete the outside array. requires keeping track of how many inside arrays you have. total pain in the ass and not worth it.

Who do you think would be better coming into learning programming, someone with experience in web development or someone with experience in networking?

I want to get into programming and eventually computer science but I'm coming off mental health issues and need to take a small course just to pass the time so my dad stops bullying me
>>54140971
>computer science
Do you like math?
Because it's basically computer math.
Think probability and worst case time complexity for a search algorithm given a data set. It's the "science" of computation.
>>54141033
I've lurked enough to understand that and I like both math and programming so computer science or software engineering seems like a valid option.
That's all in the future though so right now I'm just wondering if there's any merit to learning networking over web dev. Both courses seem to be VERY basic and primarily about learning how to function in a workplace environment and it seems like at least web dev is more actual work with dealing with markup languages compared to being a systems admin
I'm just looking for any advice I can get.
>>54141215
sysadmin stuff is cooler than webdev
it would hinder you to learn JavaScript before learning any other programming
just do sysadmin pls
>>54141215
if you like maths, you're better off in backend webdev or sysadmin, it's deeper than frontend shit
same for mental health problems - sysadmin/backend is more about dealing with machines, while frontend is more of a, uh, normieland, with all that it entails
so you're again better of in sysadmin/backend area

Personally, I'd multiply the float by 1000 and cast it to an unsigned.

>>54141789
was actually unaware of fabs(). neat little hack, thanks.
>>54141978
I have never heard of fabs though it might just be the same as abs except in a typed language
>>54142105
fabs apparently commonly does this (I didn't check my specific implementation, g++)float x;
*(((int *) &x) + 1) &= 0x7fffffff;
and abs is just overloaded for it to work with non floats also.
Anyone write "getting started with X language/framework" ebooks? Can I realistically make a worthwhile sum of money from doing so, assuming I'm good at it.
>>54142203
glibc uses __builtin_fabs, using the fabs CPU instruction on x86 computers and probably emits something similar on other architectures.
Also, in that form, that code is undefined behaviour, as it violates the strict aliasing rule.

Does anyone know how I can move a circle along this grid one square at a time? I'm using

Can anyone help me? I'm trying to code in c++, coming from processing and python.
In java/processing i can declare, lets say, ImageClass foobar; and it's unitialized, but it seems in c++ that is equal to ImageClass foobar = new ImageClass(); which is not what i want. Is there a way around this?
Also, what do i include where? Say i have a class that references another class, and both reference a framework. Do i include framework.h in every header file? Is the rule "include what you use" for every file, or is it enough if i include a thing in main.cpp?

Why is that an issue? The default constructor is the same thing as allocating memory on the stack but not initializing it. Maybe it costs you a stack frame at init time but a compiler should be able to optimize it away.
>>54143163
> Is the rule "include what you use" for every file
Yes
>>54143228
I'm not >>54139300 but it's not unheard of to use the preprocessor to get hacky "parametric" typed functions (the more popular approach was to just pass void pointers and trust downstream to know the right cast at the right time. Templates solved that problem.
>>54143294
Okay, that makes more sense, I thought they were saying that macros were a no-no or something.

However, I think it's just distributed across the group.
Either way, though, I got so much better at Java, and even improved my skills with recursion, searching algorithms, and trees, as well as learned how to do file reads (never was familiar with Java before this semester; file handling's much different than C++).
So, if nothing else, just gotta learn how the web applets work and the Swing library, and I'm pretty close to ready to make games with it, while they still don't even know what's going on.

Replace C++ from what? It doesn't really have a niche to replaced from.
>>54143528
>If you truly gave a shit about the quality of your random numbers, you wouldn't be using shit from your standard library.
Why? Maybe C programmers have a habit of dropping their standard library at the first sign of trouble, but C++'s random number facilities are first rate. You have the choice between several cryptographically secure random number generators, which can be implemented to form uniform, normal, Poisson, and other distributions.
What are good books about responsive css?
>>54143454
Java is ok.
If you know C++, you can probably get into it pretty fast. I learned a lot of it from my Data Structs and Algs class (because that's the language they decided to use).
Obviously, it has a lot of potential for web-based stuff and games (which I'm interested in).
On the other hand, it's also kind of annoying as hell...
It really cemented a lot of what I already knew about classes, inheritance, polymorphism, and interfaces, but it's COMPLETELY object-oriented. Like, to a fault.
If you don't mind OOPing every single thing you do, go for it.
It doesn't allow operator overloading though...
I can't tell you how many times I tried to compare class objects using regular operators, see an error, and "Oh yeah, just gotta ov-"
"never mind..."

https://smile.amazon.com/gp/product/B00QUBHNFI/ref=oh_aui_d_detailpage_o03_?ie=UTF8&psc=1
It covers a LOT more than CSS, but it covers CSS, CSS3, and jQuery to use on CSS in a number of the chapters.
jQuery is fucking hot.

If you are looking for personal enjoyment I would recommend against Java. It's not a bad, just very dull. I know I'm not alone when I say that I'm never excited to program in Java. The excessive, engrained OOP is annoying; it lacks expressiveness; the standard library is meh; no low level control; and who gets excited about portability.
That said, it's certainly a useful language to know, but others are more fun. Consider Python.

I understand the constraints that C is operating under. However, it's a fact that C's random number generation is really bad, and that's a problem with the language for most applications. Yes, if you are doing some embedded stuff you might be thankful that C offers and easy-to-implement standard library, but for 99% of cases it's really annoying that you have to rely on non-portable extensions to get high-quality random numbers.
>>54143566
They don't have defined dynamic data types but you can make one. That's the beauty of it. Plus, C has Glib, it's like boost for C++ and has something like vectors in it.
>>54143625
why do you need high quality random numbers?
>>54143634
Monte Carlo simulations and cryptography are two examples.

>>54143668
It's still good practice for any application to use decent random numbers. it's not that hard to invoke a function that returns a random number from Mersenne and random_device
>>54143626
>They don't have defined dynamic data types but you can make one.
Just like you have to make everything else. Worse yet is that anything truly 'generic' has to be implemented entirely in macros.
kvec is good, but it shouldn't be necessary.

When writing something that'll take a while, I tend to either listen to ASMR or 10-hour challenge vids, like Fukkireta, Miku's version of Ievan Polkka, or more recently Nya Nya Song. Sometimes, I try to find a decent techno mix, but all the Electro Swing I can find is remixes of fucking Disney songs, and the Nightcore mixes often include serious dumbass shit.
I'd say, though, 75% of the time, ASMR, 20% anime songs and/or 10H challenges, and the remaining is whatever, sometimes techno

Today I have done some Flex and Yacc programming. I think the only real challenge was dealing with nested comments for my professor's custom programming language that we have to build a compiler for. And that wasn't even really a challenge. Most everything else was reading documentation on Flex and Yacc.

Just plop in some headphones and listen to that the next time you need to focus on something. Granted, it's not much better sounding than white noise, but it does have some evidence to suggest it's good for focus and relaxation (and a number of unsubstantiated claims about other benefits)

Dealing with UML garbage. I spend more time trying to figure out exactly what little arrowhead/diamond I should be using for the relationship between two classes than I do actually designing the damn program.
Advice on aggregation/composition has ranged from "use the black diamond if the first class completely owns the second class" to "the black diamond is useless, always use the white one" to "the white diamond is not defined in UML" to "don't bother with arrows at all."
There's tons of "don't do this" with no actual suggestions about what to do.
>>54144212
A lot of ASMR actually uses binaural tracks for the audio.
It's pretty good, but I don't usually like to listen on headphones, so I don't get the full benefit of binaurals.

How the fuck do I make generic algorithms in Java?
Say I'm trying to write a sorting algorithm. The logic is all done but I need to make the sorting algorithm work with generic object arrays. This means making generic arrays, which means everything is fucked.
I can:
>Make a wrapper class and wrap and unwrap the array before and after the sorting (gay)
>wrap array up as arraylist, not sure how I would get that back to a generic array safely
>fuck it, just make the function take a list and deal with the performance hit

No, it's Business with Information Technology.
Next year, I'll be taking course in Discrete Maths, Infor Assurance, HCI, and Software Engineering.
I took almost all my business courses in my Associate's degrees, so I was able to take almost all IT courses for my upper levels.
My 2 favorite courses so far were probably Web Systems Development (my final project is gonna be similar to this website), and Systems Analysis and Design. Sys A&D was relaxing, but also fun.
I enjoyed it more and more the more complicated the diagrams got.

That's kind of a retarded restriction, since arrays are implemented with vectors.#lang typed/racket
(require math/array)
(define arr (array #[9 10 11 12 13] : Real))
(for/array ([i (in-range (array-size arr))])
(array-ref arr [vector (- (sub1 (array-size arr)) i)]))
