8E means the instruction is MOV, 06 means it moves r/m16 to segment register, 0x18F8 is the address of var1.
>>55587203
Usually binary formats will have a header that has information about the file at certain specific offsets. It's not really parsing, just look up the spec and just read the files at those offsets. Reading the actual body of the file will vary wildly depending on the format.
>>55587241
Assuming this is x86, var1 moves the address into es, [var1] would move the value at the address of var1 into es

Anyway. I have a function that includes this, but would rather it compiled to something like a state machine. There appears to be two options. Make two loops, or include the if check within one loop. The latter is wasteful. I desire a third approach where I can use the same loop for two purposes, without redundant checks (if make_upper is true, it will always be true).if (make_upper) {
while (read_pos <= length) {
ext[write_pos] = string[read_pos]^0b00100000;
//std::cout << read_pos << " " << write_pos << "\n" << ext[write_pos] << "\n";
++write_pos;
++read_pos;
}
}
else
{
while (read_pos <= length) {
ext[write_pos] = string[read_pos];
//std::cout << read_pos << " " << write_pos << "\n" << ext[write_pos] << "\n";
++write_pos;
++read_pos;
}

coding newbie here, trying to understand factories. I'm sort of grasping the concept but not the application. Is the following visualization of mine a sound analogy to the workings of a factory?
>a car dealership offers several different feature packages for a car
>customers come in and choose what they want on the car using a terminal or just filling out a checklist of options and submitting it
>the dealership sends their request to the factory, where the correct car is made based on their specifications
>the car is then sent to the customer for their use
>the customer doesn't actually know how the internals of the car work, but they know how to interface with it via the vehicle controls in the driver's seat, so they can use the car
so in that analogy:
>customer - ?
>factory - factory
>car - product of factory
>vehicle controls - interface
Is that right? Or am I off still?
>>55587990
Ah, good idea. I'll see what kind of assembly this generates later.
>>55588005
That's a very literal interpretation of factory. In the context of design patterns, a factory is a class that is in charge of creating objects.
https://sourcemaking.com/design_patterns/factory_method
>>55588053
Good luck anon. I think it's nice and readable and doubt it'll really cause an impact.
>>55588063
He did say it was an analogy. I think it fits well into how factory is used in oop.
>>55588063
>a class that is in charge of creating objects.
so it's any class because every class is made to create objects
>>55588005
OOP is bullshit
>>55588125
No, it isn't.
Some people like applying dependency injection *EVERYWHERE*, resulting in no object creation being present anywhere.
It's insane, I know, but those people then throw all that instantiation logic into a factory.
That's Java for you. Someone once said that if you pass dependencies instead of instantiating them yourself it's easier to test because you can mock the dependencies with non-expensive dummies.
Java devs took that advice and somehow came to the conclusion that it'd be a good idea to apply this principle *everywhere*, even when there's barely an advantage in mocking the object.
The resulting code was so impractical that they decided that they need factories to control the complexity they created.
>>55588063
>>55588094
So what would be a practical application of this in a real program? I'm having a lot of trouble understanding when/why you would use a factory.

>still doesnt have a logo
gl with project bruh
>>55588219
When you want your application to be put together in one big place.
>>55588197
You have to create objects somewhere anyway. It isn't dependency injection all the way down.
>>55588219
Maybe you have multiple classes implementing an interface and you want to return the instance of a certain one depending on certain context. Maybe you need to create dependencies to instantiate an object but you don't want to expose that to the user. There's many reasons.
>>55588197
I suggest you review the meaning of "class" in the context of oop. Your definition is literally that of a class.
>>55588331
What? Care to point out the parallels between that and the definition of a class?

Regarding sockets in C: A client connects to a socket on the server. The server accepts that connection and assigns a new socket to it, so that it can accept more connections. How does the client know that, despite connecting to the accepting socket, it should send() stuff to the new socket created?

>>55588492
OOP is just like material design: looks flashy but is actually shit.
>>55588317
so if you were making something like a bunch of electronics and wanted them all to have a 'turn on' function, then you could make an interface for ElectronicDevice and have 'TurnOn" as a function, then make a factory that took parameters like "DeviceName" or "DigitalStorageCapacity" and assigned them as relevant to the user's needs? ie. The user is putting together a cell phone, and they put together this parts list, and then the factory takes the interface for ElectronicDevice and builds a 'CellPhone' out of what parts were requested, and returns said object to the user? So it's a way for users to be given an interface that they can use to instantiate specific objects at runtime, but not realize that they're instantiating them?
>>55588500
I mean in general. Design patterns rose from hurdles people have come upon while designing systems. Nowadays people are just blindly told to apply them because they're "the right way" even if they don't know why they're doing it.
>>55588516

I'm working on a very cancerous project atm and I need a good way to determine the dominant color of an image.

Is go worth learning? I toyed with it a bit and it just seemed like middle ground between Python and C but not as good as either
>>55588488
Anyone? I've been trying to understand this for a few hours now, but unfortunately socket programming in C seems like a mix of outdated practices and black magic that no one is 100% of. I'm going to try asking again in a more descriptive manner.
My mental model right now is something like:Server get a socket suitable for what it wants to do (getaddrinfo + socket)
Server binds a local socket (bind)
Server listens on that socket for attemps to connect to it (listen)
Client asks the server for socket addresses suitable for what it wants to do (getaddrinfo)
[1] Client connects to a socket on the server (socket + connect)
[2] Server accepts the connection and arranges for a new socket to be connected to the client, leaving the accepting socket unaltered so it can continue to accept other requests for connections (accept)
[3] Server and client send and receive data between them (send + recv)
Server and client eventually close their sockets (close)
The thing I don't understand is: The client has a socket descriptor in [1] which is the same it uses to interact with the server in [3], but the server altered the socket that's talking to the client in [2] (or else the socket used in accept would be busy talking to a single client instead of accepting more connections). Does the socket descriptor, despite remaining the same, actually refer to a different socket after [2]? Is the client aware that it's now talking to a different socket, or is that hidden by the server? Is this information about this change relayed to the client by accept?
I'm guessing the answers are: "yes", "the client is aware, it just changes the information associated with that socket descriptor" and "yes", but I don't know how to confirm this.
Anyone? Any information would be appreciated.
>>55588658
Only if you're doing something network related.
>>55588609
But wouldn't that make it extremely hard to talk to multiple clients while accepting new connection requests at the same time? I'd guess that to be implemented as an assoc list of (client talking to some socket, local socket to forward the message to) in the socket descriptor, but it seems like it would get very inefficient, very fast.
>>55588658
go is meant for bigger projects, it's very opinionated and explicit (better readability, more annoying to write).

What's the best way to determine if a number is prime?
I can use either Java or C for this.
I tried a for loop with an if statement that just checks to see if it's divisible by anything other than itself or 1 with a remainder of 0, but the number I am working with is like 6 quadrillion so it takes forever. There's gotta be a more efficient way.
>>55588730
You don't have to check divisors greater than the square root of the number. That should speed things up considerably.

developing an android app here.
so i contact an api and i recieve back a JSON array filled with data.
within this data is strings for file names.
to get that json i boot up an AsyncTask,
the asynctask gets the strng data, and turns it into local java objects.
what do i do if i want to get those images as well?
do i boot up another AsyncTask for them alone? or do i have to get those in the same thread? what's the best way to go on about this?
>>55588730
You only need to check up to sort(number), that saves a lot of time. Alternatively you can use the sieve of eratosthenes or some other prime sieve which is faster because multiplication is less computationally intensive than float division.
>>55588730
Protip: You don't have to check every single number that's less than the number your dividing.
>>55588658
go is better than both
compare the use of thirdparty libraries across platforms, go's import/package system combined with static linking is literally perfect
compare go's concurrency primitives (goroutines and channels) and their performance with what's available in python and C (os threads)

>>55588935
>As someone coming from python
Start with the C and work your way up to the A N C E and R
>>55588935
honestly just learn rust, it will succeed C in ten years anyway
>>55588935
The C standard library is notoriously paltry, especially compared to Python's.
Learn the syntax. Learn what behaviour is defined and what is undefined. Study pointers and their relationship to arrays. Study dynamic memory allocation and manual memory management.
>>55588935
If you're used to python, you may be surprised at how barebones the c standard library is. I'd recommend getting a good book and working through it. The c primer one seems like it's good.

The highest level math was probably a grad class in functional analysis.
>>55588920
Linear algebra is so inextricable from the rest of math it's hard not to learn it. I've studied up to Markov chains and abstract vector spaces and got sick of it but general matrix and vector stuff is everywhere.

b-but muh safety
Does anyone have a copy of https://www.amazon.com/Data-Structures-Using-Yedidyah-Langsam/dp/0130369977
for (auto enemy = level.getEnemies().begin(); enemy != level.getEnemies().end();)
{
for (auto projectile = projectiles.begin(); projectile != projectiles.end();)
{
if (SDL_HasIntersection(&enemy->getRect(), &projectile->getRect()))
{
enemy->damage(projectile->getDamage());
projectiles.erase(projectile);
}
else
{
projectile++;
}
}
if (enemy->isDead())
{
level.getEnemies().erase(enemy);
}
else
{
enemy++;
}
}
Okay, so the vector returned by level.getEnemies() is actually a vector of unique_ptr. And when I try to call enemy->getRect() it gives an error saying that unique_ptr has no method getRect.
How do I get around this?

I'm still an amateur programmer, but I'd love to know more about this stuff. Honestly, I've been programming for companies for two years now, and I'm ashamed at how little I know about anything despite being the only developer.
>>55589005
Since vector.begin() gives you an iterator, to dereference the pointer you'll have to do two dereferences. (*enemy)->damage

I try to get better at programming by building something useful for me but there is no anything that will help me out so I am stuck.
This really bothers me cause now I had to practice by making prison manager programs and such. These are fun too, making UML diagrams and practise OOP design, but these are not useful.
How can I get out of this?
I use Java and C# and now I am learning python.

This has helped me immensely in being a better programmer (try starting with the medium/difficult projects)
>>55589302
Well, what I meant is that it's much more inefficient than my idea (somehow tell the client to redirect all future messages to another socket). Are you sure that's how it works/do you have any sources for that being how it works in an actual implementation?
>>55589308
Most of these require a GUI.
Is there anything that I can make in a console app?
I haven't even install a GUI designer for Eclipse. I try to write my first programs console based then move to GUI.
I did the same with C#.
>>55589381
Honestly, I think anything that can be done in a simple console application SHOULD be done in a GUI instead, if you're learning.
It forces you to learn the logic and the best way to serve and modify data behind a presentation layer at the same time.
I learned C# doing GUI from the get-go, and now I only use console applications for automation pieces that should be silent.
Buttons and drop-downs are better than manual typing of parameters, even on personal productivity tools.
>>55589364
>it's much more inefficient than my idea
you don't fully understand how tcp works; what you're thinking simply moves complexity from the server to the client for no reason and doesn't scale (you couldn't have more than 65535 open ports per protocol)
>redirect all future messages to another socket
sockets are a tcp/ip concept and are local to the machine; you can't tell a remote client anything about a socket because it's not visible outside the local machine; you're confusing sockets with ports; ports, sockets and descriptors are all different things

It's pixel sorting. It's obscenely popular actually. Especially among "glitch artists" and those montage video people.

No it wouldn't.
Do you have any experience at using OpenGL or writing shaders at all?
GLSL is not hard to learn, it's very C-like and once you have learnt it (not hard) it's a breeze to do calculations in.
>>55590841

Only a little bit of OpenGL experience I will admit.

>>55590853
>How so?
Because vector and matrix math is SO much easier to do in GLSL, the language was designed with it in mind.
And the benefit of this outweighs any downside of having to learn it because it's a very easy language to learn.
>>55590878
I fail to see what would cause problems with matrix and vector math if they used C instead of their own.

GLSL has to reflect the restrictions of the GPU's SIMD hardware. A freer language like C would allow for many ways to ruin your performance. Global memory access in shaders is extremely slow for instance. The language has to account for the locality of memory.
I don't see the problem to be honest. Few languages are more similar to C than GLSL.
>>55591017
