Your code reminds me of this one:if(Boolean.valueOf(isWhiteTurn).compareTo(new Boolean(Boolean.valueOf("true"))) == 0) {
isWhiteTurn = Boolean.valueOf(new Boolean(false).toString());
}
else if(Boolean.valueOf(isWhiteTurn).compareTo(new Boolean(Boolean.valueOf("true"))) == 1) {
isWhiteTurn = Boolean.valueOf(new Boolean(true).toString());
}
else if(Boolean.valueOf(isWhiteTurn).compareTo(new Boolean(Boolean.valueOf("true"))) == -1) {
isWhiteTurn = Boolean.valueOf(new Boolean(true).toString());
}

you only ever trigger garbage collection if you use objects very wastefully and you'd get similar speed reductions (just "smeared" instead of a momentary freeze of some milliseconds once in a while) in C/C++ by being shitty with your memory management.

It is. It also supports multi core, and in the main release too.

But it technically is type inference.
>>52650143
fair enough, though it's pretty shitty. Generics is pretty broken in Java, as I'm sure you know. That stuff pretty much compiles to:public Object ayy(Object t){
return t;
}
ayy("lmao");
ayy(new Integer(1337));
which is probably why Java doesn't care so much if you don't specify the generics types explicitly.

Scientific computing applications. When optimizing non-linear systems, it often happens that the cost reaches a peak (either even at the very beginning, or it could be later during training if conditioning isn't very good). 2^64 is relatively safe (but not always), 2^62 isn't safe for shit.

It really is. For the realm of the vast majority of everyday programming, you don't need to be smart. You just work with tools others have created, patterns others have proven, etc
Unless you're one of the few high level fags creating algorithms, doing actual CS, implementing research papers on the daily etc your work is trivial and you can easily pick up what you need to know without a degree.

All I'm pointing out is the vast majority of software development people do doesn't require a degree. Agree or disagree?
>>52650527
>keeping everything well structured/modulated and reasonably maintainable is, and shit programmers are notoriously bad at this

Yeah, it's *only* those things...
>>52650533
How so? It's inferring the return type to Collector<Integer, ?, List<Integer>>. From what I can tell the ? is an internally maintained constructed and inferred type so it's impossible to be explicit.

It doesn't need a _degree_. It _does_ need a certain level of clarity of thinking and depth of understanding, which is orthogonal to having a degree.
Dumb people doing programming results in a huge mess of a codebase, speed of development slowing to a crawl, and then - either shifting deadlines, (semi-)unusable software, or an altogether failure of a project.
>>52650396
There's no semantic difference between the two. Camlp4 is part of the distribution and can be run standalone, but the ocaml compiler can invoke camlp4 automatically during compilation.
>>52650485
>there are people who unironically believe this
It's widely known that OCaml has the best GC of any language (least latency and highest responsiveness by a wide margin).
>>52650633
LGPL can't be used on closed platforms, fampai. I wrote *GPL to be inclusive of LGPL too. Previously using LGPL v2.1 on closed platforms was kind of a grey area (even though the Qt devs sort of explicitly stated you shouldn't, in typical legal-nonspeak)

>NO OPERATOR OVERLOADING
But java itself does have operator overloading, it just doesn't let you do overloads. But inside the language there are overloaded operators. Otherwise you wouldn't be able to use + with numbers and strings.
I'm using C++ for the first time in like a decade.
I try to make all my code modular so functions are grouped together but it means I have a bunch of header files shitting up my project directory that only declare one or two functions. Is this normal? It seems awfully retarded, even while saying nothing of the idea of header files in general.
>>52650791

Because it makes it impossible to reason about a program, since you don't know which part, if any, will be transformed. You can still use camlp4, but you really shouldn't. You don't lose any power by using ppx, but you make sure it's clear where the code gets transformed (and by which extension) and when it doesn't get transformed.
>>52650796
>I want the software I write to run in as many places as possible and not be restricted by the legalese of some toe-cheese eating fat hippie fuck who hasn't contributed anything to society in many many years
Yet you were considering using that library until you read the legalese.

No he didn't, the license is cancer and now he actively goes out of his way to fuck projects up (like what he did with gcc and its AST -- as someone who's used it since the very beginning its sad to see its going to be surpassed by clang but thats solely because of his poisonous ideology)
The GPL trades everything for ideals. Other licenses have sane practical considerations. Modern day GPL software would be way better if it wasn't under the GPL.
Even Linux would have been better off; just look at how well clang is doing.

Mostly false.
You can't use GPL/LGPL v3 on iOS (without jailbreaking) because of Apple's control-freak walled-garden bullshit. Most Android-based platforms aren't as restrictive, and the (L)GPL certainly doesn't have a general prohibition on "embedded" use.
As for Qt: you're free to buy a commercial licence if you want to use it in proprietary products (e.g. anything on Apple's store).

> I thought you had to make all your shit *gpl if you wanted to use a *gpl licensed library or program with your own. Is it only true for the main gpl line?
That's the difference between GPL and LGPL. GPL requires that the entire work be GPL. LGPL only requires a) that the library remain LGPL and b) that the user has the ability to actually use a modified library with the program (which basically means that binary-only programs can't link LGPL libraries statically, and you can't use them on "tamper-proof" platforms like iOS).
Plenty of commercial software uses LGPL libraries (e.g. anything which runs on Linux, as glibc is LGPL).
>>52651210
It can't transformhello world
intoprint_endline "hello world"
but it can transform[@@hello world]
into it. Hence, it's like lisp macros (in the sense that only specific forms are allowed as transform-identifiers - in the case of lisp macros it's proc-position symbols, though, which is more natural, but less explicit).

It's only space-efficient. It's significantly more processor-demanding to do all the bit-shifting than to just do an address-offset.

So is started learning C with "C ANSI" book and I'm having problems just on start.
#include <stdio.h>
#define IN 1 /*inside word*/

int c, nl, nw, nc, state;
state = OUT;
nl = nw = nc = 0;
while ((c = getchar ()) != EOF) {
++nc;
if (c == '\n')
++nl;
if (c == ' ' || c == 'n' || c = '\t')
state = OUT;
else if (state == OUT) {

Its years younger as a project and growing at a far faster rate.
The concern of Stallman and his fellow FSF fags is politics and philosophy.
The concern of permissive fags is actually creating useful software. The kind of utility that allows people to push software without having a crack team of lawyers to consult with first, that allows people to create billion dollar business and employ thousands, that allows technology to jump forward in leaps and bounds
But stay huddled in your free software group think and keep donating to the FSF and the SFLC -- surely hunting down the odd chinkphone manufacturer to force them to post up their slightly modified linux kernel online in the name of the GPL is what the software world needs more of

i use a 23" 1080p monitor and i recommend a 27-32" 4k or 5k monitor if you can afford it. also it must be 8 or 10 bit per channel IPS, not any 6 bit shit

Yes it does

No, it's really not. For example if you need to which spaces a rook can take you & 0xFF << (8*rank), then do it on a rotated bit board(which also efficient to do). There's absolutely no, it's just a mask.
>>52651436
no looping*
>>52651436
>& 0xFF << (8*rank)
That's still more complex than "+ (8*rank)".

EOF is ctrl+d on *nix, ctrl+z on Windows.
>>52651479
You're accessing the exact same amount of memory in both cases. That is, two bytes.
>>52651479
>i don't know how L1 caches work
>>52651463
It's not the same thing, the & 0xFF is checking 8 squares, the entire rank.

non-trivial data sets often don't fit in the L1 cache
>>52651490
Thanks for Your help.
So if I want to make a simple stupid webapp with websockets I'm stuck with either python, java or javascript for backend?
>>52651526
64 byte easily fit into any L1 cache on any processor that was produced in the last 20 years.
>>52651617
what are you fucks even talking about? of course you will use more than 64 bits for most things
>>52651575
any of those will work fine.
>>52651526
>non-trivial objects
The L1 cache can hold a fucking page (4096 bytes), what kind of non-trivial local variable doesn't fit in a page anon? We are talking about 64-bit vs 62-bit integers here...
>>52651681
if you need the full 64 bits per variable which you very well could then you're fucked
>>52651638
>what are you fucks even talking about
Uh, what are you talking about? Not him, but I'm pretty sure we're discussing 64-bit ints here.
>>52651575
OCaml.
>>52651691
The point is you can just use 2 32 bit variables.
>>52651638
a 8x8 chess field
>>52651691
You can store 2048 consecutive and aligned 64-bit ints and it would still fit in the L1 cache. How often do you have frame sizes larger than that? (in other words how often so you have 2000 local variables give or take)
>>52651726
2000 is nothing and they don't need to be local you fuck
>>52651762
We were talking about representing a 8x8 chessboard as a bitmap. If you need more than 2000 64-bit integers to do so, I don't think programming is for you.
>>52651720
That wouldn't be as great, you'd have to account for pieces moving off the half boards, your check mask would need to be across 2 variables, rotations would twice as many instructions, and a bunch of other crap.
It's almost like 64-bit int was meant for chess, it just works so well.
>>52651791
any chess program with "AI" is going to be more complex than that
>>52649919
>python is shit
[Citation Needed]
You literally can't store an 8x8 chessboard in a 64 bit integer
>>52651805
Moving the goalposts are we? Nobody said anything about AI, we were talking about how to represent the board.
>>52651811
Of course you can store a completely empty field.
Or are you saying that there can only be an empty field or a figure? Are you saying that black figures should have the same values as white people?
Fucking racist.
>>52651791
As compact as you can go I think would be 8 64-bit ints, 1 for each piece(pawn, knight, ...) and 2 masks for the white/black pieces.
In a chess AI you'd need to store a lot of these to perform a heuristic search.
>>52651827
>you can store a completely empty field
No you can't you retard
>>52651820
any interesting "chess program" is going to have AI
or are you a multiplayeronly shitter?
>>52651833
Explain to me again how a field of 64 bits can't represent an empty board with 64 fields?
What data structure should I use to store a 19x19 Go board?
>>52651832
I think it would be better to use 64 individual bytes tbqh
>>52651832
That's just for the board, chess state would also include + 4 bits for available castling, and +64-bits to store en passant(when available), also 2 counters.
>>52651882
4d string array
>>52651882
my dick, probably
alternatively, as series of descriptive strings, one for each coordinate, that describes what is happening to that particular coordinate.
>>52651859
We weren't talking about the program. We were simply talking about how you represent the board itself. Stop moving the goalposts.
what's the difference?
>>52651882
long double to future proof your app.
>>52651900
why care at all about "efficiency" if you're only storing 64 bits all in all you fucking retard
>>52651875
If you mean the subtype "empty chess board" then it would only have a single possible value, and as such take up no space whatsoever.
You can't store no space in some space.
>>52651884
Most operations are much less efficient on that byte array.
Although if it's meant to be very fast, that implementation is much simpler.
>>52651904
they're probably using the terms interchangeably but shading means all colorization and lighting is specifically the light source effects
>>52651925
*not meant
>>52651904
shading is usually the act of taking geometry (polygons, usually triangles), and running it through a bunch of gpu-programs called 'shaders' to process them and get an image at the end
lighting something you accomplish through the use of certain kinds of shaders
>>52651925
person you're talking to probably didn't think of this but you can sometimes combine operations
e.g. 8x8 checker board, stored { { 00, 01, 02 ... }, col1, col2 ... }
i want to check if there's anything in one column
&FF
>>52651916
>and as such take up no space whatsoever.
But you CAN represent it that way and it would be accurate. Just because there is a better performing version doesn't mean that you can't do it any other way.
>>52651951
No you can't.
How do you represent an empty chessboard in 64 bits? Show me.
>>52651948
That would be a bit board, the 64-bit int, you can't & 0xff on a byte array.
>>52651964

As you said yourself, you need to store it efficiently because you might have heavy algorithms such as an AI. That's why storing it efficiently is important
>>52651977
No, I mean if you want to check a specific column
Plus you could do that too
Check if there's anything anywhere:
8x &FF
alt:
64x &1
