What is a level of indirection

>>58932743
It means how many times you can dereference a pointer before you hit the original stack pointer.

Also, what happens when you try to dereference beyond that?
Is it undefined behavior?

>>58932645
>>58932628
this kind of shit is worthless, toxic garbage and the community should shun it. i have nothing against lisp and i even like haskell, but advocating it on this fuzzy ineffable nonsense — this "oh trust me you'll get it when you learn it" horse shit — is antithetical to what should be in a convincing argument. it persuades people that are already on board and offers absolutely nothing to people that are even on the fence except condescension.

philosophers are able to express the nuances of different relatively abstract ontologies; programming languages are designed by humans and should be much, much easier to describe in relatively concrete terms.

if you can't articulate what other languages are lacking that lisp offers, or why haskell is better than java, then stop trying to push it.

>tfw 'programming' assembler 8051 in class and teacher is probably not a very good one

For more than a year we program basic stuff like chaser lights, pyramids and bar graphs. I get it, but I'm slow as fuck compared to C# and C (via CVI), which we also learn. E.g. I can complete any assignment, but only if time is unlimited. In case of a test or smth I'm pretty much fucked.

How do I get to do this easier besides writing actual code for the n-th time? What is the particular mindset I need for this to speed my assembler(((skills))) up?

Memery aside, I don't get all these people claiming Lisp will set your mind free. Your language is homoiconic and can do macros, sure, that's cute, but I fail to see what the fuck makes it so mind-blowing.

Fuck off Bjarne nobody likes you.

What language is best for competitive programming? Should I use a (relatively) low level language like C++ for speed or a high level one like haskell or scheme for less boilerplate and more expressive power?

>>58933628
In programming competitions, you write what you know best, and you better have practiced it 1000 times before.

>>58933628
>competitive programming
As in what?

>>58933479
I think it is because you can write domain specific languages quickly with macros and layered abstraction (separation of concerns). This makes code more robust (errors affect less code) and prototyping becomes much easier.

#include <stdio.h>
int main(void){
                       printf("Hello World!\n");
                       return 0;
}

Where do I learn more? This is the only program I can write without looking anything up.

>>58933628
I would choose python even though I know lisp or java better.
Lisp tend to be little verbose and require more thinking, java is just verbose and requires compiling.

With python you get interpreted language with kind of terse syntax which I feel is great for fast prototyping and hacky scripts.

>>58933662
But is it worth it to develop your skills in a high level language? Or are all (mainstream) languages equally good

in the planning stage of my next project and have a conundrum on how to tackle a problem.

Basically, comparing very similar XML files and displaying the differences. Mainly focusing on console/report but might look into GUI.

I could use a library like XMLunit but not sure on performance. Maybe build tress and compare them against each other. I will care about order of that as the XML files are basically maps of a web app, just need to compare changes between versions

>>58934346
No. They're not. Because expressive power is very different depending on your goals. For some applications C and the likes are very expressive. For others higher level languages are more expressive.

As for elegant i don't even know what that supposed to mean. It sounds like a 'pretty code' thing.

>>58934681
Actually, that's not what 'expressive' power is usually taken to mean in PLT:
https://en.wikipedia.org/wiki/Expressive_power_(computer_science)

As for elegance, it essentially means 'minimal': you can express all of the necessary concepts by combining only a few atomic pieces (e.g., the half-dozen or so axioms of LISP).

Anyway, I can see you have a chip on your shoulder about this, so I'll leave you to it.

>>58934714
>expressive
With that definition it's entirely useless because almost any modern language has the expressiveness to do whatever. Comparing lisp to others it's difficult to consider it anything but the same as other languages in expressiveness. You can do oop in C for example. It's ugly as all hell but it can be done.

I find my idea of it to be more useful. My idea concerns itself with the practical application of the programming language to problems. When you write in a language you likely chose the language because it fits your problem. The type of expressiveness you find in the language matches your problem. You would probably not try to do low level state mutations in haskell for example. But it's appropriate for other things.

You can't just say 'it's expressive'.

I don't see elegance as a virtue. There can be issues with too many features but compressing your language into few pieces can be just as bad because for a specific common problem you could have another atomic which handles that case well. It's a balance to strike clearly. And yes minimalist sounds exactly like code prettiness to me. It has some virtues like in the case of lua (interpreters are very easy to do), but it's not a universal good.

>>58932693
rolling

>>58934885
Did you read the article? It does go through what 'expressive power' means in the context of PLT.

>I don't see elegance as a virtue.
That's okay, I didn't say you had to :) But some people do, which is why they tout it as a benefit.

Is C++ a good language to learn as a starter and to move on to other things? I was recently gifted a Udemy course that teaches C++ by making games with unreal and the reviews seem like the course is worth it. Is this a waste of time or should I give it a shot?

No I didn't bother to read it all since you said it didn't agree with me.
Now upon further inspection I see that it does. I'm basically just reiterating what it's saying.

It doesn't tout the same definition as yours, but regardless, my point was that 'expressive power' is well-defined, and I'm glad you agree with that.

>>58932693
Roll cuz I'm a piece of shit

>>58935027
If we accept that definition, yeah. But Stallman statements doesn't fit it particularly well. And that's what bothers me.

>>58934962
>Is C++ a good language to learn as a starter and to move on to other things?
No. C++ is a good language to study for ten years and still not understand it deeply because there will still be parts of it you've never fucking heard about. Experienced C++ programmers are rare experts compared to the industry overall. Most of them are working in game dev.

>>58934127

I don't get how you can screw up these jobs where you're supposed to follow programming memes. It'd be a bit of a struggle to go against common sense all the time but still. It's not like you can't do it if you wanted to.

>>58935051
What Stallman means is essentially 'you can do a lot without typing much'. People tend to like this in languages, not just due to laziness but also because bug counts tend to be related to SLOC.

Languages have tended towards this trait with time, and for good reason.

>>58935064
I dont want to get into game dev so what would be a better alternative?

>>58935071
I screwed up because I legit didn't know, not because I refused to do it. This is the first job where I've had any kind of programming performance meme. I thought if I just did a lot of work and did it well it would look good, but because I did all of it as one big chunk I looked like an idiot

>>58935099
Python is a good language to learn early and then abandon. A couple people are gonna reply to this saying Python is "a meme" but they're scrubs who wouldn't know an interrupt handler from a parallel universe, so ignore them.

Once you've picked up some momentum, C# is a good language to use as your day-to-day tool. If you find it too difficult, give Go a shot, but I personally think Go is dumb and making things in it is counterproductive.

>>58935087
>you can do a lot in brevity
That's nice and all but the SLOC comment isn't really about serious programmers.
Serious programmer have to fight complexity. Very few programming languages help with that so far. Approaches like functional programming help because their constraints lock it down quite a bit but it's not an ultimate solution. There's more to do.

>>58935125
Just calm down and catch up anon. You will do fine.

>>58935099
Different anon here:

Depends on what you want.
For learning: Python, JavaScript, Golang
For getting a job: JavaScript, C#, Java, etc
For performance: C, Rust, C++

I'm biased of course, but Python, Golang and Rust are my personal favorites. It doesn't really matter what language you choose, you just have to stick with it.

The three languages were actually made at around the same time. Fortran was made in 1956, LISP was 1958, and COBOL was 1959.

>>58935158
It's interesting that you raise that, because expressivity, like abstraction, is a great way to stave off complexity; that's why people like it.

Anyway, we're getting off track here: you were saying that the claims mad were vague and hand-wavy, I hope I've convinced you that the terms Stallman used have a lot of meaning behind them.

>>58935355
Ah, cool. Didn't know that. I guess that makes sense considering how old GNU is, and the fact that Emacs uses lisp.

Improved this so it doesn't overflow after ~25 iterations. Now uses arbitrary precision math (adjustable, default 65536-bit because why not) and prints the first 1000 iterations in the Fibonacci sequence.

>>58935364
Yes a lot of meaning but not a single meaning. At best we can say lisp is the best language for Stallman and people who share his concerns. Which isn't a particularly impressive conclusion.
>abstraction starves off complexity
I've had this discussion before and no, usually it doesn't. When it does its often a side effect.

Abstractions are too fine grain to reduce complexity in systems. You need more coarse grain to achieve anything meaningful.

I think you'll find that 'expressive power' is fairly well-defined, but now we're going around in circles.

Poor abstractions add complexity, opaque abstractions remove it, but that's a conversation for another time.

See you later, bro.
And remember: if you're not sure what they're talking about, just try it for yourself and see.

>>58935474
It's fine, but you're not error checking strtol properly.

>>58935541
What do

>>58935541
If ptr == argv[1], it means that strtol couldn't read a number from the string.
You're just checking if it returns 0, which is actually a valid return value from that function.

Also with overflow protection in case it ever reaches > 2^131072.

Lately there is a constant effort by the SJWs to denounce C for being "unsafe" and blaming the language for shitty programmers who write code that contains bugs. It is a trick to replace C with an inferior meme language so programmers can be controlled, instead of the other way around, programmers being IN control. That is the whole point of programming, being in control. A language should give you as much control as possible, to make you the god of your own code. The SJWs want to stop you from being a god.

1 gave me a think for a half second
2 did as well - but not sure of any system which wouldn't crash on the null pointer dereference anyway so it's a bit of an odd one
3 was obvious, aliasing is always the answer on these "tricky" questions with pointer arguments
4 applies to many other languages too
5 was obvious and quite banal
6 was super obvious and another banal "trick" question we see so often on these "C is bad for you and here's why" quizzes
7 bleedingly obvious UB from the start
8 another common banality of "hiding" the comma operator in what looks like real syntax
9 & 10 amazing, signed overflow isn't defined? this is C 101
11 there's a different range in negative and positive range? waow never would have expected that

It's a matter of style.
I understand why someone wouldn't want to do it, but I'm not vehemently against it.
If the variables are somewhat related
e.g.

int day, month, year;

I'm not against it, but if they're a bunch a different shit, I'm more against it.
When it comes to pointers though, don't mix that shit together with normal variables.

>>58937747

It depends how crowded the line is, and whether or not the vars are related in some way.

for instance:

int width, height;
int bitDepth;

I don't declare variables in chunks. I hate people who puts a block of declarations at the start of the function without any context whatsoever. Just declare each variable right before you start using it (so do declaration + initialization) and you will rarely have that dilemma

pleb here

anyone here knowledgeable in bash scripts?

Been trying my first bash script, and I'm trying to move all files with a filename that matches a string of an array and put it in a folder with that name

like, i have an array MONTHS = [jan feb mar may apr... and so on] a bunch of pictures with file name "april2016", another bunch with "may2016", I want to move all the april pics in a april folder and all may pics in a may folder

as of now the way i'm trying to do it is

for file in ~/../public/pictures #folder with all the pictures 
do
     variable = 'MONTHS[@]' #save the current month iteration
      for file in ~/../public/pictures
              ls -l | grep -c -i  #and i dont know what to do from here
               done
        done

I'm trying to find a way to feed ls -l to grep's standard input to read the filename and then move whatever file matches the current array variable being read

Any anons could shed just a little bit of a light my way?

I know it will be fucking trash, I know some assembly but not C which is what I would prefer to use.

>Scheme > Common Lisp
Why?
And is Idris just haskell with dependent types?

>>58940086
The graduate-level operating systems class at my University used C++ to build an object-oriented kernel.

>>58940183

Trying to figure out how exactly this implies it being trash??

At the kernel level basically until you implement the libraries to support all the fancy c++ shit, it's pure old school c programming.

>>58940183
Really? Did they use assembly as well?

>>58940206
I would prefer to use C as C++ is just unnecessary, I just don't know it.

>>58940210
>Did they use assembly as well?
Of course. Assembly is undergrad tier anyway.

>>58940206
You still get to use templates, inheritance, operator overloading and lambda functions.

Easiest fucking class I had, he was just giving away A's. He even gave a lecture near the end of the semester about how if you've made it this far then you should get a free pass, he only goes hard on the beginner courses. I kind of agree with him on it though

Is a decent summary for the minimal requirements.

>>58932693
Eh. Bored at work

>>58940230
Would you recommend holding off on this project until I am stronger with c? I have been putting it off for too long anyway.

roll.
Gotta go to uni first though

Quick question: I am looking to log to a file with 30 or so lines per second being generated (each line is in the region of 100 characters) in C#. I'm thinking I really shouldn't be attempting file I/O that often so I want to occasionally dump a stored buffer of these logs every now and then (not specific period just "append all the shit stored to the file and start logging fresh"). What's best practice for doing that? I can't have a fixed-length array for the bytes because I have no idea how long it will store for. Currently I'll be adding a line to a list of strings and presumably when I want to dump into the file iterate over the list, combine it into one byte array then write that single array to file.

Maybe a stringbuilder using
<code>
byte[] info = new UTF8Encoding(true).GetBytes(value);
fs.Write(info, 0, info.Length);
</code> ?

>>58932693
Do I get to use any language?

I've been learning the python but I don't really like object-oriented. I feel an affinity towards imperative, almost want to learn fortran; is functional good?

>For big important programs do you need to rewrite all the variables you used upon closing?

Not unless you're worried about someone reading it. By say running another program that is given that memory and reading it without initializing it. Some luks commands make sure keys are no longer in data. For best security you should zero out any sensitive data as soon as you don't need it. Nobody can steal something from you if you don't have it.

Using string in this manner is very inefficient especially if your pulling an item from the front because it has to shift.

Lisp is perfect whether you use it or not.

>>58940379
Right so I'm thinking of stringbuilder currently. 30 times a second I'll be appending 100 characters to the stringbuilder and every now and then (region of 10-30secs) convert that stringbuilder to a byte array and write to file.

>>58940347
Use a data structure such as a queue. Do you know how to build a circular array? Does the ordering of the information matter?

Yeah I just don't really use C#. All I'm trying to do is avoid hammering file IO cause I'm sure it'll fuck up performance. Don't think memory will be anywhere near an issue with the volume of data I'm collecting between dumps

>>58940435
Just throw them in a linked list then, quick and easy

>>58940455
yeah it's the next part once you have that linked list though. I've got a LL of 3000 lines. I want to write it in one IO operation instead of 3000. So shouldn't I just use a stringbuilder (I think append is O(1)) to generate a 3000 line long string then append that single string to a file?

Use C because writing _good_ C++ is very difficult and takes at least a decade to master. Not even most C++ experts know everything about the language.

It's easy to write C++ that works, but it's hard to write high quality C++.

>>58932693
rolling for an ASM thing aswell

>>58940529
k

rolling again tho

>>58940547
yeah no

>>58940498
yes

Since death is perfection, no wonder Lisp is the Latin of programming languages.
