Thought for the day
Having strings compute their hash when they're created and use that for string comparison

>>62301784
second for op is shit

>>62301800
Better thought, have a generic hash + value container that works for more than just strings and lets you avoid modifying the string type.

>>62301818
That makes more sense

p://www.emulator101.com/reference/8080-by-opcode.html

This guy says here that on 8080, little endian is used.Ok.

But let's take for example
00 00 00 c3 d4 18 00

he says that its:
NOP
NOP
NOP
JMP $18d4
NOP

Why are d4 and 18 reversed after c3?

I have a hard time understanding little/big endian.It is an extreme clusterfuck for me.

>>62301800
>strings don't change
>>62301818
std::unordered_set

Oh boy I sure do love functional programming yes sir I do

>>62301844
I don't mean a container of multiple values, I mean a container of a single value that computes a hash and uses it to accelerate certain operations.

>>62301800
>>62301818
Have the hash generated at comparison time if it doesn't exist already, if it's already been generated just use it.

>>62301836
> Why are d4 and 18 reversed after c3?
Because it's little-endian, the least significant byte, d4, goes first.

>>62301844
Can have it recomputed with assignment

>>62301784
Hey goys, what is the problem here? I can't find it.

I have this function

std::ostream& operator<<(std::ostream& os, Rational const& r) {
    os << r.num() << '/' << r.denom();
    return os;
}

I try to do this:

    Rational r1(1, 2);
    Rational r2(2, 4);
    Rational r3 = r1 + r2;

    std::cout << r3.num() << "/" <<  r3.denom() << std::endl;
    std::cout << r3;

And I get this:

 error: invalid operands to binary expression ('ostream' (aka 'basic_ostream<char>') and 'Rational')
    std::cout << r3;
    ~~~~~~~~~ ^  ~~

>>62301869

so the rom file there is in big endian?

On the fence about dba stuff, exclusive and coders whine but watevs

>>62301959
No? Everything is little-endian, go read the wiki.

>>62301925
>I have this function
To be clear, that is a nonmember function, right?

>>62301925
What if you use just Rational r as the param without const reference?

>>62302013
fucfuckfuckfuck
I just realized, I only implemented it in the .cpp and didn't declare it in the .h
thanks doe, you made me check the header file

>>62301925
It looks fine, must be something with the compiler not being able to find the operator implementation. Where did you put it? It's better to have it as an inline function in a header with Rational itself.

Is Smalltalk worth learning? Is it an interesting language?
I've already learned OOP with C++, but Smalltalk is apparently a very well liked language

>>62302088
t. Uncle Bob

>>62302088
Yes, Pharo looks good and it has a lot of nice documentation, literally several nicely done books, I've been thinking about giving it a try for a while now. Stil tho, don't expect it to be of any practical use other than experience, the language is inherently slow, the libraries and community are non-existent and everything good was stolen by Python and Ruby decades ago.

can any one explain the array of pointers casting. is (void **) lineptr is equivalent to (void *) lineptr[]

>>62302134
sorta.

>>62302134
An array is not a pointer, an array will decay to a pointer to the first element of the array when referenced as a non-array.

What specific line/problem are you having trouble with?

>>62302151
why the need for another * though since we know from preceding declaration that lineptr is an array of char pointers. now wouldn't it make more sense to cast (void *) lineptr ?

>>62302253

>>62302269
Obviously you have to test the strings themselves if the hashes are equal.

>>62302269
Stop having shit luck

>>62302292
. . . so a guaranteed efficiency loss if we're in a situation where most of our comparisons are of identical strings, right?

>>62302134
>is (void **) lineptr is equivalent to (void *) lineptr[]
no.

>>62301800
Java sort of does this, it saves the hashcode value for the String when it is computed and uses that.

For C++ it would be very easy to make a type of structure that wraps an immutable object and stores the hashcode.

>>62302345
Yes. If you have a finite set of strings you can use a perfect hash function, of course, and then you don't need to compare both the hash and the string each time.

>>62302226
can you help me with this >>62302235

>>62302374
Yeah of course that'd happen in that case. But if, for example, we have unknown data which always tends to contain many repeats, a perfect hash function wouldn't be possible so the whole thing would be a pointless exercise

>>62301784
Totoro!

>>62302408
If you anticipate having many equal strings, a solution might be to have an indexed set of strings that acts as a perfect dynamic hash function. When a new string is encountered, it's checked against all the strings in the set. If it's already in the set, you assign it its index. If not, you add it to the set and assign it the next index. Then you can simply use indices to compare strings already in the system.

>>62302482
Seems like a good solution. I'm fairly convinced that this is a decent idea now.

>>62302391
Here's my best guess, qsort expects an array of pointers to something(void), lineptr is an array of pointers to chars, if you were to do (void *) lineptr you'd be casting the array as a pointer to void which it isn't, it's a pointer to a pointer to a char, the function wants the base address of the array which is **lineptr.

I'm no expert so I could be wrong on this, I often have to reference documentation when dealing with shit like this myself.

It's not really accurate to say 'Calculus is easy/hard/anything', since it depends to what depth you're studying it. Same for algebra, topology, anything really.

>Having strings compute their hash when they're created and use that for string comparison
Dumb idea. Who said the user wants to waste cycles computing hashes for strings that will never be compared to anything (which could very well be the vast majority of them)? If you really want to support this use case out of the box, provide a fast compare method that computes and caches a hash on demand.

>>62303730
You need to create the base application in java, then you can use something like SDL with opengl for graphics. There are existing templates that you can just for the java project. You can check sdl's android examples or something like that.
You could also compile GTK for android but there's some limitations.

>>62304073
If you want truly non-bloated applications, write everything in assembler.

If you want to produce apps this decade, stop worrying too much about bloat.

In Java, I have an iterator that fetches every thread on 4chan.

Iterator<Thread> threads = ... 

Obviously I dont want to keep all the threads in memory at once, so my iterator lazily fetches new threads as they are needed. The tricky bit is I only really care about all the posts in the thread, so I either want

Iterator<Post> posts = ... 

or

Iterator<Iterator<Post>> posts = ...

is there a way to create posts without destroying the lazy fetching of threads?

what is this exactly

Im new to java and im having trouble producing function code. Does anyone know the boofa command?

>>62305440

:send is a method on every object in Ruby that takes a string or symbol, and any number of arguments, and sends the string as a method to the object, with the rest of the arguments as arguments to it.

1.send :+, 2 # resolves to 3
1.send :eval, "puts 'hello world'" # What do you think happens?

>>62305551
>1.send :eval, "puts 'hello world'" # What do you think happens?
idk ruby, but let me see

1 shoudln't have an eval method right?
or maybe it has an eval inherited from above, since ruby is interpreted if i remember correctly

basically it runs eval(1, "puts 'hello world' ")

if that's the case then that's indeed wacky

>>62305551
>eval is a security risk
stop the fucking presses

>>62305438

Ruby is vulnerable iff:

1. You are dumb with untrusted inputs
and
2. You take advantage of its flexibility

>>62305609

eval is a private method defined on the module Kernel, which is included by Object. send doesn't care if a method is private, protected, or public. You can use public_send as an alternative, but since send is a public method...

Anyways, it's not a language I would use for a server per se. It's a super flexible scripting language though.

But it's also good for servers. Just don't use that ugly motherfucker Rails, but take something less confusing and more elegant, like Hanami, Cuba or Sinatra.

Yes, Sinatra is what I would use if I needed to use Ruby for a server. But strictly speaking, I don't see running servers as its strong point.

Right, but it's not often the Ruby way of doing things. Ruby doesn't have to be verbose if you don't want it to. In fact, you can make it as ugly as Perl if you really prefer. Also, you don't seem to make a lot of use of string interpolation, which can make things shorter. For instance...

You can cut back on the + operations on line 70 like so:

puts "Writing #{lines.size} lines to total..."

And you can merge lines 76 and 77 into one line like so:

puts "Game against unlisted team encountered #{line}"

Oh, and I just realized you never closed your open file in create_team_hash

>>62306376
Wouldn't it automatically get closed after the call to create_team_hash when the GC kicks in?

>>62305905

Python and Ruby are similar in many ways. So it's probably more a matter of personal taste.

I prefer Ruby because it has more things "out of the box" without imports, and I find the syntax easier to remember.

But that's just me, I don't want yet another flamewar..

# print all ruby files in current directory
puts `ls -a`.split.grep(/\.rb/)

>>62305991

I would look into Hanami, it's a better/cleaner/newer version of Rails.

But honestly, I'm trying to get away from Ruby and think about getting into Clojure for webdev. I'm just not good enough (yet).


>>62306085

Your pic is not ideomatic Ruby code, it's not very well written..

For example lines 59-67:

def create_team_hash
  File.open('/home/(...blabla..)/index.txt').each do |line|
    # do matching here
  end
end

Also:

>ruby is too verbose and wonky

I've done Python and Ruby, and Ruby is one of the very few languages that is even more concise than Python. The main reason is that Python just hates functional goodies while Ruby often reads like an OOP version of Haskell..

(1..100) . filter {|n| n.odd?} . map {|n| n < 50 ? n**2  : n**3} . reduce :+

>ruby
>verbose
you should explain how you came to hold this opinion

>>62306718
>

puts `ls -a`.split.grep(/\.rb/)

that's not a very portable way to do so

I'd say there's 10% right off the bat that can't be solved no matter what due to a broken sample image, incorrect answer key, or other issue

then there's probably a further 20% that can be solved by people but probably not by a bot, for example an image that is partially obscured but a person can tell what it is (street sign?) and fill in the last letter or two

they also add new squiggly fonts that your bot wont be able to handle until you train it by collecting enough samples manually
which they then remove after a month to make you feel like you're wasting your time
