Maybe? I don't know what you mean anymore. A loaded question means a question that incriminates you in some way regardless of the answer. That doesn't make sense here.

>>57166514

It's a way (one of many, but the first one I always try) to spawn a TTY shell when you exploit a machine and have a non-interactive shell.

Newbie here. What is the proper way to do this, or how would you handle this:

>I have a page to edit a specific document in Db. It takes an `id` param.
>I have a class to regroup all validation functions, one of them checking if the id exists in Db.

I felt like if I were to check if the id exists in Db, and only after fetch the entire document, it would be a waste. That's two Db request a bit for nothing.
So right now, I do something like this:

>The validation function returns false or the object.

And in my controller, there's now something like this:

if($document = Validation::id($id)){
    // ...
}

Is that okay? I don't really like the fact that my validation function returns a bool or an object. I think it should be either one.
But searching for the id to see if it exists, then searching it again to get the document seemed like a waste of time.

How would you do it? Is there a proper way to do this?

I'm the other guy. I agree it's not a fantastic benchmark. I wrote one of them. Basically, the benchmark comes down if your language has a package or can link to a package to do the work for you. Not actually doing pidigits, just how well the language can link to other packages.

You can traverse from one point to the next if it's within a certain deviation (ie. +- 5) from the first point's value

>Best OS if I'm going to be learning C, C++, Java?
For Java it doesn't really matter. For C++ I prefer Linux because of its tooling, because installing libraries on Windows is a bitch, and because you effectively have one compiler on Windows. There's MinGW etc. on Windows but if you're using those, you might as well get the real deal and install Linux.

For C it's no comparison, C development support on Windows is non-existent.

what can someone do in functional programming that one can't do in OOP?

Any 'oriented' paradigm can do anything because it accepts you move outside the paradigm itself.

>>57167781
(You)

>>57167781
Write code that adapts to changing requirements. OOP only works if you can plan everything out ahead of time and stick with that plan.

>>57167621

What's wrong with bootstrap? It jest werks.

>>57167831

We'll never know if that's true because a large software package has never been written in a functional language, nor will it ever be.

You'd actually have something of scale to measure up adaptability to changing requirements. Chances are, your super neat fizzbuzz will never change, and so you haven't got a good frame of reference.

>>57167933
>Chances are, your super neat fizzbuzz will never change
But not because it's small.

Whenever I am with C++ programmers they always need to tell me that C++ can do nearly everything C can do and even more than that, and that I should just switch to C++.

To which I always reply that I could start writing in C++, but then it would basically just be C again. And then those programmers would start foaming from their mouths because I don't use their static/reinterpret/dynamic/const/whatever casts and use templates only when necessary, which is almost never.

In other words: I am not using C++ not for my sake, but for others'.

>>57167952
C is indeed okay. C Primer Plus is an okay book because it will introduce you to memory and how compilers work early on, which is good.

>>57167953

That's really not an argument. Large projects are, as a rule, more susceptible to change than smaller projects.

>>57167975
It's for both of your sakes. You obviously don't want them to start having pseudo-complaints about the code rather than a neatly bundled 'you're using the wrong language'. That's why I stopped using C++.

>>57167995
Well, obviously. In any case, "a large software package has never been written in a functional language" isn't true in the first place.

>>57167995
Technically, no. The relative amount of change is smaller the bigger the codebase.
This is what happen when you dig your own shithole out of fallacy.

>>57168002
>'you're using the wrong language'

If that was the case they wouldn't tell me that I should switch to C++ in the first place. To them, anything should be solved in C++.

You will often hear about how FP is great for prototyping and rapid development, i.e. without things being meticulously laid out beforehand. That's my experience with using those languages as well.

Though I'm sure your idea of "large" has been warped by overengineered OOP codebases. Large should refer to scope, not LoC. Functional languages are also great at expressing a lot with a little.

post the project

The one "killer feature" of OOP, encapsulation, is basically irrelevant now that we have dependent types. Instead of maintaining an invariant by hiding implementation details, you just put the invariant in the type and code that breaks the invariant will simply not type check.

Of course, there's also hiding implementation details for the purpose of abstracting yourself away from them (e.g. for cross-platform) but that's not an OO-specific thing at all.

>>57168214
Sort of in line with this. But when people say that they're C++ 11 programmers and 'only use useful abstractions' what should I be weary of especially?

If that was true nobody would use OOP because without encapsulation you don't really have any objects without twisting the definitions, i.e. a function is an object that responds to the "call" message.

>Dependant types doesn't seem ready for use though.
If by "ready for use" you mean "implemented in a mainstream language" then no. But that's only because the languages haven't taken off, for the same reason all new languages have a hard time taking off.

That doesn't really mean anything, but thank you for clarifying.

>>57168393
First: this
Second: there are also padding bytes inserted by the compiler to make memory accesses faster. Everything that is align to the native word size of the processor will usually have the best speed (unless we're talking about special things like SSE/AVX)

in C++ why can literals be strings, but to store them you need the library?
what the fuck

>>57168515
You don't need the library. You can keep them on the static data segment of your application (which is really fast) rather than using the library and thus heap memory (which is really slow).

Also, it's a C thing.

>>57168515
The literals are just a faster way of writing

 'f''o''o''b''a''r''\0' 

. It's not C++ and you can use the char type with this.

How about you make the language yourself? You've obviously abandoned any hope of producing anything that runs super fast so just go for it. You'd be out of luck in the 70's and 80's but now you can just do whatever, fling shit on the walls. Have every variable in a hash table at runtime and just say fuck it.

Just write your God dammed front end. If it's good enough people will clean up for you when you're done.

Thinking about it some more, you're probably right.

That said, it's because "compiles without overhead" is kind of meaningless. Overhead is relative.

>>57168723

I hope you're just memeing.

>>57168786
>Why do Rust programmers virtue signal in bold like breathing?

It's a result of their inner SJWism.

>>57168783
You have never compiled Firefox, then. g++ takes a STUPID amount of time compiling ONE source file.

>>57168786
If Rust were 100% safe, it would be useless. That's why there's really two Rust languages: safe and unsafe Rust. Safe Rust is guaranteed to never produce a memory error, assuming the compiler is performing to specification. Any memory error has to come from somewhere within unsafe Rust.

It's a mistake to think that unsafe Rust poisons the safety of safe Rust. There is a DMZ between the two, and that is "unsafe {}". If there is a memory error, there is either a problem with some unsafe Rust somewhere or the conditions of the boundary were violated.

That is all Rust claims.

>>57168830
Oh, you mean compiler performance and not the performance of compiled code. Still, "overhead" is meaningless without a baseline.

>>57168804
>This has nothing to do with concurrency or safety, these are regressions, they're bugs.
Yes, and the rust compiler is written in Rust, so it should have no bugs. You should never believe the malicious, autistic lies of "rustaceans".

>>57168843
There are more problems than just memory errors and Rust doesn't purport to eradicate them all. Just memory errors.

>>57169209
Anon, a pointer simply is the memory address of a variable. When you write

int x = 3;
int *ptr = &x;

You're saying that the value of x should be 3. Then you're declaring a pointer with * (don't let this mix you up with a dereference, they're completely different), and assigning it the address of x. You get the address of x with &.

A dereference

printf("%d\n", *ptr);

"Dereferences" by following its memory address to the actual thing and printing that out. Think going to a house instead of just reading the address.

int array[3] = {2, 4, 7};

Declares an array of 3 integers. When you use just the name "array", you're actually given the address of the first element IN that array. So "array" refers to the address of 2. Cool part here, increment the array by one gives you the next element in line, so the address of 4.

You can pass this array and any other pointer to anything just by giving the address over to a function

function toThree (int *p) {
  *p = 3;
}

function .. {
  int i = 2;
  toThree(&i);
}

>>57169236

>your random temperature in god knows what location, at any time of day, being somewhat high for a winter, is an indication that the entire world is experiencing some form of consistent temperature "change", whatever that may be, of any significance
no really dude, you actually could have skitz. i know you're just going to think im a "conspirator" or whatever too, but this kind of behaviour is a really common symptom, if not one of the defining ones

No problem. As a protip, you should learn to figure out how to use Google intelligently to solve problems like this. For me, it was the first result for common lisp multiple value return.

why are you continuing to attack an anecdote instead of presenting facts?
what next institutions like the NOAA, doctors in their field, are not calculating correctly nor are their computer simulated tests? or are you just thinking of a small time frame that doesn't span past your lifetime?

>>57169694
i think you're expecting too much out of this syntax, which i think they're trying to phase out anyway
and you're not really using it! something like print('a ' * 3) does the same thing

>>57169958
>instead of presenting facts
signed yours truly, anonymous skitophrenic that keeps stating the world is collapsing and everyone who doesn't think so is religious

What tests? It's a bunch of hippies looking at an extremely mild CHANGE, not for better nor worse, and exclaiming the world is imploding. Like u

I joined the conversation out of context, and didn't even mention climate change

weird dude, but seriously,

Check this section out because a lot of it sounds like it might apply to you. My grandmother passed from complications of skitz recently, and she said very similar things.

Not an argument.

Next thread, use when this one dies.

thank you for agreeing at last, you can't argue against facts.

>>57170070
What fact?

Would it be possible to add these two lines of code with assembly editing, or is assembly editing only for simple tweaks and deletions?

public static Equipment FC_AnchorCannon;
EquipmentManager.FC_AnchorCannon = new Equipment("Anchor Cannon", EquipType.FixedCannon, 1f, 2, AbilityManager.L_AnchorCannon, false, new StatModifier[0]);

thanks for your response.
I'm pretty much a total beginner so I have no idea what can and can't be done
