Maybe it's because IRC requires a client and forces you to be online to see replies to you?

I've never really understood the appeal of idling all day on some dead channel.

>>56718630
i see literally no minors i like because i want something that goes with csci but hate stats and math, and those are the 2 minors. so i think i'll take the csci electives i think look cool

>>56718622
So I've just read through K&R as revision for C as I haven't done any in months.

But I feel I should write a decent program in C before I move on and claim C as "learnt".

Or should I just get on with learning OO and consider C learnt?

>>56718656
learning curve I guess. Nice GUI for Discord, whereas irc needs typed in commands.

Slack is just irc too, but it's much nicer to use.

Thinking about starting to put my github on my resume, only problem is I do like 50-100 commits in one night then nothing for weeks will this matter? what makes a github good for resumes?

>>56718656
I thought grown-ups used Slack?

For Discord, inline images/media (including emoji), modern interface, stronger social features, voice chat. Plus I think most people around 18/19, maybe even 20 have never even heard of or used IRC.

>>56718688

50-100 commits a night may look hacky.

Can someone please review this code and tell me if anything is glaringly wrong before I complain to the professor? It's worth noting that we could only upload a single text field and we haven't learned best practices for classes yet so I didn't use them, and that it's a Java class and not a general CS class so I wasn't expected to implement my own algo.

As much as I like IRC for it's simplicity, most people already think IRC is some complex text-only thing from the 90s and telling them they need to set up some external service to collect replies while they're offline is going to scare them away.

shitty code desu

Why are accessors for data structure all so non-standardized?
Shit, even Arrays and Lists in every language I've ever used have different method names for retrieving length

>>56719011
Because different languages have different design philosophies.

>>56719011

length :: Foldable t => t a -> Int

Haskell

>>56719011
Sometimes I think syntax and actual languages should be two separate things that you can just mix and match to your liking. But then I think it'd probably be more hassle than it's worth.

>>56718809
Why do you have this saved?
https://warosu.org/g/thread/S56453560#p56457825

>>56719028
no I mean
within a language
Array and lists have different methods to call to retrieve how big they are and that's just silly

Am I right in assuming fork a project, git pull it from my fork then when I git push it only pushes to my repo?

>>56719118
>Array and lists have different methods to call to retrieve how big they are and that's just silly
In what language? Getting the length of a array is generally just reading an int. Getting the length of a List usually means it needs to be calculated. It's often felt that the difference needs to be distinct to programmers.

if you want the original repo to merge your changes, they need to pull your branch and merge back into their master branch.

nah
It's not some sort of magic bullet but it works very well.

>>56719191
Yeah, just not as well as other stuff people can be using instead.

>>56719243
Java is cross-platform, has lots of support and third-party packages, and it supports a LOT of web-related stuff right out of the box so it's very friendly for that.

Also, and this is a more recent development, it's actually not slow. It's slightly slower than other languages but not by a lot.

There's no reason to use it over .NET these days.

>>56719345
Alright
I'm not related to this discussion but here's a question I've always been afraid to ask
What the hell is .net in this context? I know that C# uses (or is?) it, but C# only runs on Windows machines... but people always claim that .net is cross-platform.
They also say things like "I'm a .net developer" without specifying a language
someone help me out here

>>56718622
I just realised
>tissue box on the desk next to the computer

>>56719368
>but C# only runs on Windows machines...
This is wrong. C# targets .NET which is cross-platform.

>>56719391
Oh, my bad
I must have been thinking about XNA

>>56719405
XNA proper is not cross platform, but it is effectively cross platform because FNA implements it.

To answer your original question .NET is a platform analogous to Java's JRE. In fact, much like you can take a .jar and run it on any platform with a JRE, you can actually run a .NET exe on any platform that supports .NET (assuming you don't use an non-cross-platform stuff).

>>56719368
.NET is basically the C# ecosystem. The runtime, the libraries etc.

>C# only runs on Windows machines... but people always claim that .net is cross-platform.
C# runs on all platforms. More so than Java even.

>They also say things like "I'm a .net developer" without specifying a language
.NET supports many languages, not just C#. Here's also VB.NET and F#.

https://en.wikipedia.org/wiki/Common_Intermediate_Language

C#, F#, and VB are all languages with different compilers. Well, C# and VB use Roslyn now, and F# has its own compiler. These compile the language so it can talk to...

.NET, which is a massive set of libraries, tools, and a runtime that takes the instructions from the compiler and converts this all to CIL that can be interpreted by the CLR into straight bytecode.

Or something like that.

In any case, the current .NET 4.6 runs on Windows. It's equivalent is Mono, which is an open-source cross-platform implementation of .NET that is now funded and supported by Microsoft.

There is also .NET Core, which is also open-source and cross-platform, but it is a limited feature, lightweight implementation of .NET.

Xamarin is built upon Mono, is also open-source, and is used to port .NET's capabilities to mobile applications and OSX.

In fact, I think the only thing I've mentioned that isn't open-source and MIT licensed is the .NET 4.6(and prior), which only runs on Windows.

good, looks like this time you remembered the 6 million.

    if (age <= 10)

        if(weight < 80)
        {

        }
        else if(weight >= 80 && weight <=200 )
        {
            System.out.println("You must ride the " + rc[1]);
        } 
        else if(weight > 200)
        {
            System.out.println("You must ride the " + rc[2]);
        }
    } 
    else if (age <= 20)
    {
        if(weight < 80 )
        {
            System.out.println("You must ride the " + rc[3]);
        }
        else if(weight >= 80 && weight <=200 )
        {

OK, so this takes care of any negative values. Now how do I handle letters?

JAVA ISN'T GOING TO LET SOMEONE STORE A LETTER IN AN INTEGER YOU FUCKING BAKA, YOU DON'T HAVE TO CHECK WHETHER OR NOT THE INTEGERS ARE LETTERS

>>56719743

You need to prevent yourself from reading bad(malformed) input in the first place.

Java has something called hasNextInt for integers to check if the input you will read will be something else in Scanner. Read more about it here.

https://docs.oracle.com/javase/8/docs/api/java/util/Scanner.html#hasNextInt()

Once you have established the input will be an integer and you read it in, you can just check if it is greater than 0.

That should solve your two problems.

>>56720013
I think Java as a built-in isNum() function, you might wanna google that [spoiler]I wish you luck anon but holy fuck do you need to git gud

>>56720013
Ok, here's the thing.
All standard input is received as a stream of characters.
Your language's standard library is automatically converting things that look like numbers to integers.
It's smart enough to ignore non-numerical characters, hopefully.

>>56720052

It's going to throw some exception if it does, I would think.

You catch the exception and do something in reaction to it.

>>56720104
yes this is what I needed, how do I do that?

>>56720118
catch

>>56720094

What do you mean? Any letter of the alphabet or anything that isn't the '-' character + 0-9 should return true if you put it through Scanner.hasNextInt();

So putting in 'ass' will return false for that function. The only thing that will return true will be pretty much negative and positive numbers so only after you get true from Scanner.hasNextInt() should you use Scanner.nextInt() to read the input.

>>56720150
Not him, but is that really the best Java's got? The logic for checking whether something is an integer and the logic for actually parsing a string into an integer, possibly failing, is practically identical. You have to do duplicate work just to avoid an exception?

>>56720150

* Any letter of the alphabet or anything that isn't the '-' character + 0-9 should return false if you put it through Scanner.hasNextInt();

Sorry for that mistake.

>>56720150
This is an issue that simply doesn't exist in modern software development because the issue of user input sanitation is a solved problem.

And it starts by not using the standard I/O library to read numbers without checking the numbers first.
What you should be doing is take the entire inputted string, tokenize it, and then check if the first token is a numerical string.
Then dump the rest and ask for more inputs.

>>56720212

That is the only way to do user input nowadays. Any other way is not acceptable.

The problem is that the jump from doing simple user input with Scanner.next* to that is quite a jump. I'm just not sure if it is wise to let beginners do this for simple input.

     // Obtain user input.
    System.out.println("Please enter an age.");
    age = checkValidInt();
    System.out.println("Please enter your weight.");
    weight = checkValidInt();
    
    
    // Selection structure
    if (age <= 10)
    {
        if(weight < 80)
        {
            System.out.println("You must ride the " + rc[0]);
            
        }
        else if(weight >= 80 && weight <=200 )
        {
            System.out.println("You must ride the " + rc[1]);
        } 
        else if(weight > 200)
        {
            System.out.println("You must ride the " + rc[2]);
        }
    } 
    else if (age <= 20)
    {
        if(weight < 80 )
        {
            System.out.println("You must ride the " + rc[3]);
        }

    else{

    }
  }
  return -1;
}

What is going wrong ?

>>56720301

True, but string parsing isn't something you teach beginners until near the middle or end of an introductory course.

Restricting input when beginners expect input and output to be equals and as easy as one another sucks.

>>56720349

You can't just post what's going wrong with code. Say something about what it is doing when you run it. Like segfault, wrong values output, etc.

>>56720349
You're running the program and it's not giving expected output
Hope that helps!

>>56720212
Why would you tokenize the whole thing only to throw most of it away? Just try to read in a number until certain characters are reached and then either finish or fail.

>>56720368
>string parsing isn't something you teach beginners until near the middle or end of an introductory course.

        MOV EAX, FFFF0000h  // Move constant into EAX
        AND EDX, EAX        // Bitwise AND. Store result into EDX
        MOV EAX, 00001041h  // 00001041h is the original entry point

        JMP EDX             // Jump to the address store in EDX
    }

My executable patcher now works around ASLR. Very fun to watch in a disassembler.

NewMain()

is now the new entry point and will jump to the old entry point given at memory offset 1041h

>>56720520
You can express the exact same thing with FAR less code using for loops. It will also be less error-prone since you don't have to just copy/paste and change parts, which is easy to mess up.

That said, it looks like you've dug yourself into a bit of a hole by using named components instead of a 4-component array. You could probably retrofit it by using an anonymous union, though.

Decided to learn CMake. Figure I'm probably going to need to use it eventually. That said, it's got some weird quirks about it. For instance, on Windows, it defaults to MSVC. I would like it to default to MinGW, and if possible, never make an attempt to use MSVC. It also uses -std=gnu11 if you set C_STANDARD to 11, rather than -std=c11, which is... awkward.

Not that it matters. A shitty programmer may have more useful program ideas. They're implement it badly, but it will be implemented as an idea for people to enjoy. A good programmer may very well do the same, but may be shy about sharing for code, or using it for anything. Who is more successful?

Haskell, [700, 700 - 13 .. 200] is a list consisting of the values 700, 700 - 13, 700 - 26, ... 206

GHCI is a repl, so if you entered that it would print it back to you

>>56721988
That is it. Just a simple loop, like everyone has done a thousand times in class.

Just... instead of looping from 1-10, loop from 700 to 200. And instead of increments of 1, do decrements of 13.

Much, much simpler than FizzBuzz.

But if a person cannot program, they cannot do it.

>>56722022
Why did you choose an ending value that won't be hit?

>>56721968

I believe that the problem with this is that if you were counting down from 700, decrementing 13 each time, you would never reach 200. It would either print 206 or 193 at the end.

for (var i = 700; i > 200; i -= 13) { console.log(i); }

This will count down to 206, not 200.

Add an expression whose result is a function closure. Evaluating (function x E) creates a function that takes parameter x and yields the value of expression E. (x is required to be a symbol).

For example, expression (function d (plus d 1)) yields a function. If the function were called d, it would be defined by f(d) = d + 1.

A function is allowed to use variables that have definitions at the point where the function is built. For example, evaluating (eval-expr (function q (time q w)) ((w 4) (r 20))) yields a function f defined by f(q) = q*4.

Accomplish this by representing a function in the form (closure x E env) where x is the function's parameter (a symbol), E is the function body (an expression) and env is an environment (the environment that was in effect when this function was evaluated).

Aye. I'm just saying that there could be a source of confusion caused by the fact that, in counting down by 13, one would not reach 200. Regardless, however, that was not the problem raised by your candidate. The problem was that he was a retard. I am curious to know what your more "advanced" questions would be. That is, to show that they know MORE than someone with a week of programming skills.

Because really, that is just a basic for loop. It can be one lined in any language. It even looks cute in CoffeeScript.

>>56722113

Format of output was unspecified, and therefore open to interpretation. Printing to stdout is just a standard way of obtaining an answer.

>>56722196

Shouldn't that be *= 13? I think he did a *= 13. I am not sure why, however.

I am not looking for the next Carmack. Just proving that you can do some intermediate programming tasks would be sufficient. I have not actually thought of anything beyond "count down from 700 to 200 in decrements of 13", because I have not had candidates pass that yet.

>>56722282

>because I have not had candidates pass that yet.
I am not sure if I should be optimistic or pessimistic. On one hand, if a good portion of my competition in the workplace is total retards, my actual experience (though I have not a ton to show for it aside from my degree) may be more valuable. On the other hand, too many idiot programmers means that a lot of the infrastructure that I will be working with is going to be built and maintained by idiots.

>>56722169

A halfwit could do FizzBuzz even without knowledge of the modulo operator. Just store the remainder as a separate variable that is incremented, and reset every time it hits 3 or 5. As long as you know how to use variable assignment, for loops, if statements, and basic arithmetic (literally just + and -), the problem is trivial.

>>56722400
>Would interviewers tell you what the thing looked like?
They might, or might not. The point is not just to test your "dry" skill, but to also see how well you can think on your feet, in cases of ambiguity.

I remember reading about an interview technique where they ask a general question with an open solution: "A restaurant is failing, and you are hired to help. What do you do first?" Then, whatever answer you give, they will say: "And if you cannot do that, what will you do instead?"

People can memorize FizzBuzz without understanding it. Companies want employees who can think, not just memorize!

>>56722319

>What is your problem?
it's making a scheme interpreter in scheme. the instructions have us do it piecemeal, adding small bits of functionality

first, a number is evaluated to itself, and then we added cases like (plus 1 2) to read the head of the list and perform that operation on the tail parameters

then we added if capability

then we added an environment, which is another list separate from the expression that is a parameter to the evaluation function, and contains associations between symbols and values. so (evaluate 'y '(y 5)) results in 5, because y is 5 in the environment.

the next part was tricky and it allowed the evaluator to interpret (let (x y) e) where x is associated to y in the environment, and e is then evaluated. i managed to get this working, except for when y is a function itself.

this next part i'm stumped, pic related. i have no idea what to do. genuinely 0 clue. it might be because it's late. i suspect it has something to do with lambda, but i don't see what that would work within this context
