Most obscure does not really mean anything for reverse engineering, but it does possibly mean that you're going to be using instructions that may not be as well optimized by the chip producer.

its code obfuscation, I don't care about speed. This is only meant to replace certain operations in non-performance critical pieces of code, mostly I/O bound stuff.

The choice for C over C++ for a beginner is to get a sense of how a program manipulates data in memory without the complexities of higher level abstractions getting in the way. It makes sense to learn the lower levels of abstraction first, as it is easy to see how higher level abstractions are implemented, and how they can save you time programming in the future. Knowing C allows you to understand how higher level languages are implemented, and can give an appreciation for many of their design choices and tradeoffs.

There are a few reasons why C is a better choice for beginners than assembly languages:

1. C is generic, assembly languages work on one type of processor only, and may have a different way to interface functions on different operating systems as well.
2. C is structured. Most commonly used programming languages have loops, functions, and if statements in some form or another. Assembly has none of these. It is so distinctly far off from regular programming that knowing assembly cannot be said to transfer over.
3. Assembly is way too fucking tedious compared to C, even for basic tasks.

>>58431962
C code with C++, sorry.

>>58431929

It's not that C is more low level than C++.
It's that idiomatic C++ has more high level abstractions than C.

It is not difficult to describe to a beginner the printf function. Describing std::cout opens up a can of worms because cout isn't a function; it's an object. The function call is the << operator. In effect, you either have to explain a lot in the beginning, teach C++ like C, or tell the beginner "this is a special syntax and we'll worry about it later." Personally, I feel that no beginner should be satisfied with, "we'll worry about this little bit of magic later."

I'm making a bot to play HentaiVerse for me (muh credits, and it's a good opportunity to learn some new stuff) using Python + Selenium.
I want to have four spells active at all times (Spark of Life, Regen, Haste, and Protect), so as part of my battle subroutine, I have the following code:

filenames = {'sparklife', 'regen','haste','protection'}
        for x in filenames:
            try:
                driver.find_element_by_xpath('.//*[@src="/y/e/%s.png"]'%(filenames[x]))
            except:
                #cast relevant spell
                
                print('Spell expired: %s . Recasting.'%(filenames[x]))
                success = castSpell(self, filenames[x])

Basically, when the spells are active, there are icons on the top of the screen. When the spells expire, the icons disappear. That means that an exception will be thrown when a spell expires, and the catch routine re-casts it. The xpaths for the spell icons are, for example,

.//*[@src="/y/e/regen.png]

.

I'm getting the following exception:

 File "C:\Users\You\My Documents\LiClipse Workspace\HentaiVerse\HV1.py", line 385, in fightRoutine
    print('Spell expired: %s . Recasting.'%(filenames[x]))
TypeError: 'set' object is not subscriptable

Anyone know what I'm doing wrong here? I can't work it out and Google isn't helping.

This is literally my first Python project, so I don't really get what you're implying. I'm sure there's something simple I'm not understanding in terms of syntax, but if I had the knowledge to get the point of this post, I wouldn't have an issue in the first place.

>>58432804
>Try printing <filenames> before the TypeError thrower (line 385, HV1.py).
That spits out
{'protection', 'haste', 'sparklife', 'regen'}
Which is pretty ordinary-looking to me.

>>58432852
This is probably the issue. Does "for x in filenames" make x into the string itself, or is it an integer index (this is what I had assumed)? My program crashed somewhere else, but it got past this hurdle when I replaced all of the "filenames[x]" with just "x".

>>58432922
>>58432934
Since you can only complete one action each turn, the "success" is whether or not the turn was actually expended. If you try to cast the spell but don't have enough mana or it's on cooldown, you want to do something else with that turn. Basically there's a

 if success: continue 

in the while loop somewhere.

>>58432958

>>58432958
>filenames[x]
>TypeError: 'set' object does not support indexing

for file_name in file_names:

>>58432958
You're definning a hash table or whatever it's called in python (I think it's "dictionary") without key-value pairs. Use an array (tuple, list?) instead.

That's why >>58432800 pointed the {...}.

>>58433033
Yeah, I guess that makes sense. I'm not sure how I came to believe that it was an index.

>>58433036
I think you're also right - I should be using the square brackets. I think it converted the dictionary to an array in compilation, but it's still sloppy even if it works.

>>58433077
>I should be using the square brackets.
if its a static list then a tuple is the correct pattern. Only use an array if you want the code to update it with new values.

All in all another disappointing Vim presentation that absolutely misses the point on what makes vim good.
And what's unfortunate will still newbies to the wrong direction (spacemacs + evil instead of emacs, neovim instead of vim, bloated vim with shit plugins instead of plain vim).
The guy sure has some skill though, but the sneaky way he attacks Vim and Bram with misinformation is low class.

also vim has async now, and neovim has had it even longer.

>>58431906
I'm not wearing girly clothing, I'm just egging on the other anon.

>>58433591
I still think that async isn't worth it in a text editor, it makes things complicated for no reason.

But Vim has it now and anyone who wants it can use it. I just hope the base Vim behaviour (make, grep, quickfix, omnicomplete) will stay synchronous.

If an operation in a text editor takes too long, making the operation async is just masking the problem, I believe a better course of action is to wonder if you really need this very slow operation in a text editor and find another faster operation.

And not all time adds up. Waiting 2 seconds for ctags to scan your files is not the end of the world as the async proponent pretend.

Is there an editor with a feature (or a plugin) which draws each level of parenthesis in a different color?
Just thought that might be something cool, but someone probably did it already. It doesn't really need to draw each level in a different color, 3-4 colors would suffice to distinguish between them, so it wouldn't fuck with other syntax coloring. Different brackets could have different palette.

Async is very worth it in some cases.
But I agree that it shouldn't be used for everything, because that would be retarded.

Things that take a long time that you want to let happen while you edit should be async. Things like uploading/downloading over the network for example. Consider git, or running Maven stuff, and that sort of thing. It makes things slightly better, and enough slightly betters makes for a huge difference.

Should grepping your file be async? Fuck no. Should pushing to git be async? Yes. And it's worth having the extra complexity there.

But you need to have some taste and style to make that distinction.

C, of course. Also, reported to the FBI ;)

>>58434869
Nah, too many ways to fail like buffer overflows. I need something more secure.

How do these people function?
It just bothers me so much when people can't analyse their tools in an objective manner. He later does the sin of complaining about the libraries he chose, libuv, for having function callbacks.

I can't go on, people like this put me off a language completely. Fuck.

>>58434887
If you're worried enough about buffer overflows, forget it. You're not skilled enough to engineer a ransomware.

>>58434920
So people who wrote OpenSSL are also not skilled enough?

Yes, I am, I'm just aware that everybody makes mistakes and it's easier to account for that when your language works with you, not against you.

>>58434843
asm

>>58434843
c++ is better

>>58434887
lmao, stop while your ahead

>>58434887
>too many ways to fail like buffer overflows
Sounds like a personal problem.
Also buffer overflows tend to happen in overcomplicated code or just be the straight up obvious mistakes when indexing.

Just write your own language/compiler first so analysts have issues.

>>58434920
>You're not skilled enough to engineer a ransomware.
That's a stretch, it's a babby project.
>>58434934
>So people who wrote OpenSSL are also not skilled enough?
I'd say yes actually. Opensource overall tends to be quite a mess when it comes to security, too many chefs who obfuscate their security flaws.

>>58434843
I've been meaning to write a programming language for malware which compiles highly non-deterministicly and in a very obfuscated manner with easy access to undocumented APIs and the ability to do easy ROP chains and shellcode. I just never really work on it much anymore.

>>58435008
It doesn't matter. Most malware targets normies. Normies won't know where to look for solutions. The most successful pieces of malware can be shoddily slapped together in high level languages unless you're doing this as an exercise in computer security. Even metasploit can be useful in real world scenarios despite being detected by literally everything.

Not sure why, but I'm stimulated af after drinking tomato passata (homemade, I usually dilute it with water, so it's basically a tomato juice). It's far, far more stimulating for me than coffee. If i drink too much of it I literally can't sit in a chair for longer than 5 minutes. If I drink it in the evening, I'm guaranteed to spend a sleepless night. I'm pretty sure it's not a placebo effect, but it might be something very specific to me as I haven't heard anyone beside me and my mom to have similar experiences with it (idk, maybe something to do with my neurochemistry?)

Ok, I'm trying to setup Vim for the first time.

But what fucking filetype should the _vimrc file be? It only seems to work (affect vim) when it has no filetype designated and this is hugely annoying and obstructive to editing the actual file.

>>58435192
you call it .vimrc and you open it in vim to edit it dummy

>>58431906
C is like latin a century ago: it doesn't have that much real uses for everyday dev, but is a de facto lingua franca of programming languages and is used to teach you how to program properly (like latin was used to teach proper grammar)

>>58435215
.vimrc is an illegal name in windows though

I've a file called _vimrc with no extension type thus not allowing it to be defaulted to open with Vim.

>>58435233

I'm using debian and I have no issues with opening a file without a filetype in the file explorer. what kind of error do you get?

I am learning c# and after i used

System.Math.Sqrt()

Method i tried to see its source code, how did MS programmers implemented it

When i Go to Definition i only get this

//

        [SecuritySafeCritical]
        public static double Sqrt(double d);

This still doesn't explain anything. Where to find exact source code?

>>58435245
S-sorry. I saw my professor using it in class and couldn't believe how quickly and effectively he could edit his code. It really appealed to me since I've long felt my IDE to be a cumbersome bloated thing which I didn't even use half its functionality for (so..many...buttons...). but maybe you're right, it does seem Vim on Windows is more of an afterthought.

>>58435320
No error, Windows just lacks an associated program for the non-file type, so it prompts you to choose something to open it with, but since it has no designation you can't make it a fixed option. I guess it's not a big deal...I just thought, surely this has to be some type of file? I tried making it a .vim file but then Vim ceased being affected by it, so, yeah.

>>58435342

return pow(d,0.5);

>>58435353
aren't there options for this? right click it and properties or something so you can set what program this file should be opened with

Again, this only works if it has an associated file type. A file type file cannot be associated to a specific program in Windows. You must designate everytime what to open it with.

Hey I asked this yesterday, but asking once more (will probably not ask after that). If you're interested in learning about computer graphics with c++ as the language and opengl as the api, would you like to form a two-person team where we will communicate over IRC (or whatever) and share our insight about what we learn, and write code, read books/articles, compare implementations etc.? I think it will make the process more fun and together we might learn quicker compared to alone. Like a programming pal kind of thing.

>>58436166

Started learning python today, I got this simple exercise : writing a program that counts all the vowels in a word, here's my solution :

#!/usr/bin/python3
   
   count = 0
   s = str(input("type in a word : "))
   for i in len(s):
       if s[i] == 'a' or s[i] == 'e' or s[i] == 'i' or s[i] == 'o' or s[i] == 'u':
           count += 1 
   print("Number of vowels:", count)

and it says "TypeError: 'int' object is not iterable" for line 5 (so the initiation of the for loop), what's wrong ? I've been at it for 30 minutes, can't seem to find a solution

In Clojure, I have these two functions

(def mult-by-2 (partial * 2))
(def my-inc (partial + 1))

And I want to apply both of these functions to a list/sequence, so I do the following:

user => (map my-inc (range 0 10)) 
(1 2 3 4 5 6 7 8 9 10)

user => (map mult-by-2 (range 0 10))
ClassCastException java.lang.Long cannot be cast to clojure.lang.IFn  clojure.core/map/fn--4785 (core.clj:2644)

Any ideas why? I can't seem to apply the mult-by-2 function to sequences, but I can apply the my-inc function.

this is for the ((->) a) applicative
you can also use "pure" rather than const

here's another

f >>= k = \ r -> k (f r) r

and since

f >=> g     = \x -> f x >>= g

you get

(f >=> g) x r = g (f x r) r

(i think that's accurate?)

This leads to magic like

Rust is "designed to be faster than C" but in real programs it's almost always slower than Java. The compiler is very slow (because it's written in Rust) and single-threaded (what happened to "fearless concurrency?") and the core team admitted that this will take at least a year to fix, in which time no new features will be added to the language. Error handling is very cumbersome, far more verbose than in other languages, and the way it's implemented yields constant branch mispredictions no matter which path is taken so they don't even have the excuse of "doing it this way is faster than exceptions."

But that's all just icing on the cake compared to the real problems. Remember, the entire point of Rust is to make a language that automates manual memory management without using GC. Originally they said it would not have memory leaks, but after some users discovered a design flaw they quietly dropped that claim from the sales pitch. In the last few months more of these design flaws have been discovered that produce a variety of use-after-free situations. They're blaming most of these on LLVM, or stalling and saying they'll get to them after the compiler rewrite is finished in a couple of years. Meanwhile their would-be users are abandoning the sinking ship in droves, moving to languages like Go and Nim where the compilers are written by competent programmers instead of a crack team of token minorities installed by Mozilla's department of virtue signalling.

Doesn't matter, there's no reason not to act like you're the king of the world. If you do, many people will believe you actually are, since you're acting that way.

>He should respect himself, his skills and his time much, much more, otherwise everybody will keep stepping over him. Pathetic.
Making up his mind to behave like an actual male will not cause his balls to descend. He's incapable of taking what he wants because he doesn't know what he wants. His body doesn't make the right chemicals for that.

>.vimrc is an illegal name in windows though
It's not. Dotfiles are legal in Windows. If they weren't, every git user on Would have a lot of problems with the .git directory and .gitignore file.

Filenames in Windows are allowed to contain any unicode character except for the following:

<
>
:
"
/
\
|
?
*
NUL (integer value 0)
Any character with an ASCII value between 1 and 31 inclusive.

Not allowed to use the following names: CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9

Not allowed to end a filename with a space or period, however filenames are explicitly allowed to begin with a period (i.e. .temp)

I firmly believe it's all in the mind and it's all a matter of attitude. If you're a skilled engineer you are literally among the top 1% of the most intelligent people on the planet, even if you're pretty shit. Not even mentioning all the time and effort he wasted posting on his little blog. It's pathetic, and he deserves ridicule until he mans up. I could dissect his entire post in many ways but you guys are all thinking the same thing as me anyway.

>>58437717
Yes it is.

.vimrc would not be allowed

..vimrc would be

Windows assumes the dot operator in the first delineates the point between the file name and the file type, thus there is no name, which is not permissible.

>I firmly believe it's all in the mind
You don't have a mind. You have a brain. It's part of your body and exists only to obey the needs of your body. The quality of your body and your quality as a person are exactly the same. If you're a fuckup, if you're unsuccessful in life, it's always because your body is fucked up.

If you don't know this, it means you're a beta SJW cuck.

It's good for learning, solving a simple problem in a complicated way, instead of a simple one could help to learn. What other way would you do it?

Jesus, what a bitch. He should try applying to Microsoft though. They were famous some years ago for hiring people like that on conditions no one would ever take if it wasn't MS. I guess that's the charm of big names; they attract abundance of skilled but other than that somewhat dysfunctional people.

Is there a tool that I can use to make sure if I add a new field to a datatype to also change a method that needs to consider all fields like equality or a hash function? This is just an example. I'd like to use this for serialisation and deserialisation.

What language is this for?

ew

>>58438294
C++

>>58437933
>>58438409

Okay, so you've got a C++ class...
And you want to add or remove a field...
And you want this tool to change all methods on that object associated with all previous fields?

How is this tool supposed to have an idea what the intent of these methods is in the first place? Even if it's something as simple as equality, it's not always as simple as using == on all of the fields...

>>58438467
I don't really need full automatic code generation. I just want to see a warning if I forgot to change two related things.
e.g.

class Foo {
    int x;
    int y;
}
//some annotation like
all_fields(Foo, Foo.x, Foo.y)
boolean operator==(Foo& left, Foo& right) {
     return left.x == right.x; //y is ignored in this case
}

// now I add a field
class Foo {
    int x;
    int y;
    int direction;
}

//to stop the warning
all_fields(Foo, Foo.x, Foo.y, Foo.direction)
boolean operator==(Foo& left, Foo& right) {
     return left.x == right.x && left.direction == right.direction;
}

A simple solution would be an external tool that verifies if I've manually annotated the operator with the fields I've already considered and if a field is missing then it would show a warning.

>>58438693

I do not think such a tool exists. Might be an interesting project though.

Hello /g/,

I am extremely desperate, that's why I'm here. I'm studying Bionformatics. And I am looking for whatever example source codes based on machine learning for thyroid cancer detection.
