Why is not ok to say something like "if there's a black history month why isn't there a white history month?"?
Is the implication that white people don't need it?

because white history month is all other months.
>>52287434
The implication is that blacks have very little history, whereas the entire world history is centred around white Europeans, Eurasians and Eastern asians.
>>52287434
It's just racism, plain and simple.
Black people will tell you that racism against white people doesn't exist and not realize the irony in doing so.
Also, the fact that white people aren't really allowed to have their own culture in of itself speaks more about white people than anything else.

Actually, we don't. We don't need parades or a month dedicated to how awesome we are. We already know we're #1, you couldn't even fit all the white accomplishments in a month anyways.

If a weeb worships japan and only enjoys things that comes from japan, is that still his culture?
I need logic help
let's create a simple betting game
you can spend between 1-100 dollars on a round
you have these three types of peices
green chips - costs 1 dollar
blue chips - costs 2 dollars
red chips - costs 3 dollars
you can buy whatever chips you want.
however you don't know the effect of the chips, you think that sure, the more red chips you buy the better off you are but you don't know the multiplier - perhaps it's only twice what the green chips yield in the same value
luckily I have 10,000 round results with random amounts of the different chips
I can tell you how much was spent each round
but how could you solve such a problem?
the actual problem I need to solve is even more complex than this but I simplified things
>>52287559
Dude, this is unsolvable...
>>52287558
That's his culture as he chooses to join that culture.
>>52287558
Sure.
>>52287558
nope
his culture is his original one (unwanted, during childhood), mixed with the one he wants
and that's better like that, so he can have a different view when he encounters the culture he likes, and so modifying that culture
>>52287559
Where is the actual bet in the game?
>>52287559
I still don't understand the spec. It feels like it's missing the idea about the multiplier.
>>52287549
Nope.
>>52287559
don't get the purpose
what does motivate the algorithm?
analyzing 10.000 rounds with probabilistic AI?
Why does learning OpenGL have to be so hard?
Why is every tutorial so shit?
I just want to draw some rotating triangles...
>>52287467
>the fact that white people aren't really allowed to have their own culture
because white culture is kkk, lynching, segregation, slavery, pedophilia, genocide, hitler, ... white culture is being replaced for good reasons, trust me.
>>52287600
I sortof forgot that, I don't think it changes things though
lets say the chips increase your chance of "winning", getting a return of 150% on your investment each round
really this is looking at CSGO rounds mathematically.
you can spend 8000 dollars on a full buy or nothing. you can win the round either way.
but there is going to be a linear relationship between the amount of money spent and your chance of winning the round. I have already successfully parsed all that data, I have about 5000 rounds sitting around.
see this problem is incredibly complex, what you should buy, since you have to think what causes a win in the first place. But we don't have to know how the exact probability increases if I buy an awp or not. Just that it does, in a linear fashion.
So here I am trying to decide what the best way to conduct my analysis is going to run on. Because the goal is to say: ok you have 2700 dollars and an ak an kevlar. buy a flashbang, an HE, and a helmet to have the best chance of winning the round.
see the money is linear, right? but we don't know the probability.

>>52287699
haven't said that but racism takes a large part in the the white culture (same for japanese)
>>52287694
Traps, you say?
>>52287559
On the most basic level, each of the results you find which color 'wins'.
Average the results
Take the average, and each case where a certain color was a higher percentage than the other two and the result was higher than average, give it a 'point'.
Color with the most points wins, you can sort of determine which color is the best to choose.
You can get way more in depth with some statistical formulas, taking into account standard deviations from the average score and by how much above or below the average result is, as well as factoring in percentages of the colors used per round.
Having typed all of this, I just realized that you don't know how many of each color was used each round.
Problem unsolvable, no way to analyze colors as a factor, other than if the amount spent was 1 or 2 dollars.
>>52287725
this is bullshit
white people are the least racist
white people invented "all races are equal" etc bulllshit
>>52287725
Pretty sure this is bait, sounds like a false flag straight out of /pol/.
>>52287693
Where did you get your data?
In a normal game the loadout isn't really randomly picked.
People have their standard loadouts that they are comfortable with and will take those.
Also what about all the other variables?
One player may be used much more with generally less efficient weapons, or different maps favour different loadouts, etc.

>>52287559
>luckily I have 10,000 round results with random amounts of the different chips
>I can tell you how much was spent each round
>but how could you solve such a problem?
I would start by looking at amount spent : number of chips played.
If you can find certain combinations you can solve it directly.
For example 1 dollar spent : 1 chip played = can only have been the green chip, green multiplier = result.
4 dollars spent : 2 chips played = can only have been 2 blue chips, blue multiplier = result / 2.
So basically: Enumerate all possible ways to add up to amount spent using the chips and see if you find any unique matches.

Whats the easiest way to get a C compiler for my architecture? i can't write a compiler, I'm already busy with the assembler, linker, and machine.
I don't want to learn Clangs backend API because it's C++ and it looks like a clusterfuck and I hate C++ code, can i get away with translating LLVM bytecode to my assembler language? are there any libraries that parse LLVM bytecode to an in memory format or will i have to do that too?
I really just want a C compiler, I want to focus mainly on developing the VM, assembler, and linker. Compiler is too much for me to handle.
I want a compiler that fully supports C11 and has competent optimization, so no garbage like lcc.
>>52287819
It's fucking true you idiot
You know there are still fucking african tribes hunting albinos so that they can eat them to gain their magic powers? You know there is plenty of racially motivated anti-white crime in South Africa? You know 90% of what the left does is just hating on white people? You know white people are being displaced from nearly every western country?
>>52287862
honestly, I can't think of any non-white culture that thinks highly of white people
>>52287864
>I suppose it's not actually important to find the precise percentages
Actually, if you want to do a proper statistical analysis, it very much is.
That being said, you're talking about getting into some college-level actuarial stuff, so...

You haven't been to any African refugee camps then, obviously. They actually distrust black/native workers and accuse them of stealing the food for themselves and being corrupt, and only trust whites to actually distribute food fairly and evenly.

If you don't have a compiler, what are you using to make executables for your architecture?

>>52287901

Of course not...
>>52287918
>Of course not...
Well, of course maybe on this board, silly me... I forgot where I was.
But jokes aside, I have two friends (one of them my ex) that went to Africa for two years to work with Doctors Without Borders in my circle of friends, and my sister visited a camp for a couple of days when she was studying.
I'm going to make project Euler solutions in a GUI application for fun.
What are you programming for fun today, anon?
>>52287912
every race in history has colonised, mass killed, genocided, enslaved, etc.
white people were just the most successful race

>>52287910
My assembler and linker run on my host machine.
Assembler code -> assembler -> own object format -> linker -> flat binary -> VM
I don't have an OS on the VM, so ofcourse i have no assembler or linker actually on it either.
All i need is a C compiler that runs on the host and produces assembler code for my architecture, then i just feed that into the chain above.
>>52287912
That has nothing to do with the race.
If the native Americans were white it would have still happened.

This
Vikings went on raids throughout Europe and Russia and took slaves wherever they went and then sold them to Arabs in Constantinopel.
Where do you think the word slave even comes from?
From slavic.
>inb4 slavs arent white
>>52287880
my major is applied math, luckily ;)
econ, particularly
however I meant that you don't need to... well ok lets look at it. you're right, I think. Every peice needs to be weighed against the probability of winning, balanced in order to set priorities.
The chip problem is solvable by isolation of the determining factor
if you look at all the instances where green == red and note the number of blues vs the chance of winning you can get the amount it increases your odds by, if you control for the other two.
It's fuzzy in my brain but I think it'd be doable with some trial and error.
>>52287958
Advanced societies form when it is tough to live solely off the land. If it is easy to live off the land, there is no need to start farming or buildings to live in and work in.
>>52287955
Clang it is, so the easiest option would be to translate LLVM bytecode then.
Also, is there a library that parse the bytecode into an in-memory format?

You're right, anon, what I posted was extremely vapid and simplified the advancement of societies.
To add, another detriment is lack of free trade with other technologically advanced societies. All of Europe and Asia were able to learn from each other's advancements due to proximity.
>>52287994
what does "good" mean?
>>52287944
You do know that you can make both gcc and clang spit out assembly, right? Just make them compile for some really reduced (but similar) instruction set, and then make an assembly translator that translates between that instruction set and your own.
I guess you could write your own back-end, but I don't see why you would do something as complicated as that if you could just parse a text file and do simple substitutions, provided that the instruction set is similar enough.

Most of the vikings were not raiders though. We were farmers, fishers and traders. Saying that vikings were violent raiders, rapist and murderers is like saying that the Roman Empire was all about military conquest and nothing more.
>>52288015
I guess i could do that, I'd rather avoid parsing text though, I've had enough of that from my assembler.
Would translating some text assembly for another architecture really be easier than translating LLVM bytecode?
>>52288024
>Does postgresql use the same query syntax as MySQL?
They both use SQL
Postgres uses a dialect of SQL though, that supports stuff like procedures.

They established trade routes all over the known world. They were 80% traders, 15% explorers and 2% violent raiders and 3% mercenaries.
>Not the retards they left at home.
They all went home. It was uncommon for one single viking to do more than one such raid during his entire life, as one raid would provide riches and slaves to last a life-time in viking-age Scandinavia.

I haven't done nearly as much work in C#, but the only really outstanding difference was how much better UI work is in C#, and JavaFX has improved things a lot on the Java side recently anyway.

There are legitimate criticisms of Python though. It is incredibly slow by programming language standards. It's probably actually the slowest programming language in widespread usage. The whitespace syntax throws many people off, since the most widely used programming languages all use "{}" and ";", and it can hide subtle errors with no indication. Everything is an Object hides the real value of OO programming.
It's a good jumping in point for programming, but that's about it.

It's a common misconception on /g/ that Python is only suitable for prototyping stuff. It is one on the most mature scripting environments out there with libraries and frameworks to do anything from heavy number crunching and video analysis to full-fledged web frameworks, and the only reason /g/ still holds on to this myth is because they somehow think that Python is just another Perl.

>It is incredibly slow by programming language standards. It's probably actually the slowest programming language in widespread usage.
While you can argue that "hurr durr python is slow" because of how it handles concurrency (aka the dreaded interpreter lock) and secondly because it lacks a proper JIT compiler, the fact that it is widely used for number crunching should make you stop and think for a second. It's a well-known fact that any library worth anything in Python is implemented in C, and even large parts of the Python standard library is implemented in C.
>The whitespace syntax throws many people off
It really doesn't, as most people do in fact indent their code regardless of whether it is required or not from a syntactical point of view.
>and it can hide subtle errors with no indication.
Python is no more prone to scope errors than any other language, but it does not have block scope (scope is on a function namespace).
>Everything is an Object hides the real value of OO programming.

>>52288640
People who are using Python for number crunching obviously don't need real time performance, or their "crunching" isn't as hard as it might seem.
Sometimes code can be better formatted by breaking the usual formatting rules, if you had to do that in python, can you remember how?
Everything is an object doesn't mean everything is a first class citizen, it just means that everything runs slower.
Also, the one advantage of Python is that it is easy for new learners to pick up. This ends as soon as you start trying to do GUI work in it, which lots of learners want to do. Have fun pulling your fingernails out with tk, or trying to integrate with a GUI toolkit written in a different language. In my personal opinion, C# (I actually shudder saying this, but it's true) is a better beginner language than python. It may be more complex, but OO concepts are much easier to learn when you can explicitly see them all the time, rather than hidden behind the curtain like Python does. Yes, you can do explicit OO in Python, and you should at a certain size, but it's similar to the old "To learn C++, you must first learn C" argument.

Yeah, I'm sure all the use of numpy in academia isn't "hard" at all, amirite...

You're talking like Python enforces a single kind of formatting, it doesn't. The only requirement is that you are consistent, and if you format your code inconsistently you are a shit programmer desu senpai.
>Everything is an object doesn't mean everything is a first class citizen,
It does in Python's case

Python's argument was never one about speed. If speed is your argument, then any language besides C, C++ and FORTRAN are shit. Is this really your argument?
>the one advantage of Python is that it is easy for new learners to pick up.
And a direct consequence of that is that seasoned programmers are able to cut the cost of development drastically as well.

>Have fun pulling your fingernails out with tk, or trying to integrate with a GUI toolkit written in a different language.
WTF are you talking about? Do you have any experience with this at all, because it really doesn't seem like it. The GTK+ python bindings are easy-peasy, if you're familiar with GTK in any language the same concepts apply in Python. The same is also true for Qt (PyQt)....

>>52288954
>This is what Python script kids actually believe
This is what any tech competent would actually believe, as most of the reasons anything is considered "slow" these days is because they are IO bound. There are some exceptions, but these are usually solved by implementing smarter algorithms. The last resort, when you have eliminated IO bound stuff and optimised your algorithms and data structures is to speed up the calculations themselves, by implementing them in said languages and exploiting architecture specific features such as vectorisation (SIMD, SSE) and GPGPUs (CUDA, OpenCL).
Doing network traffic or writing stuff to disk is equally slow in C++ as it is in Python and in Java.
>>52288958
I prefer the more modern XML style layout stuff, or the amateur hour VS drag and drop designer. So many amateur Python applications use it, and it looks even worse than Java's Swing, if that is possible. I never looked very deeply though, because I had a bad first impression of it.

Baby duck syndrome
>>52288995
OO is probably the least intuitive paradigm. They only teach it to beginners in university because it take a while to grasp if you don't understand the 'why'. And shouting the why at students faces doesn't do shit. They must experience it.

>>52288974
> Just use OpenGL, unless you like fucking with platform compatability/hardware independency.
If only it was that simple. Writing OpenGL code which is actually valid (rather than "works on my system") isn't trivial. All implementations let some errors slide, but the details vary from one to another. For anything to do with memory coherence, you can screw up heavily and it will typically work most of the time, but fail often enough to be noticeable.
>>52289036
All of the above
If it's not on a given platform, either it's because of politics (Apple) or because the hardware isn't general-purpose enough (like pre-GCN or pre-Fermi)

Not only is that a completely different point that I didn't say anything about, but it's bullshit. There are plenty of slow tasks that have nothing to do with IO. Python is a slow fucking language and there's no way you'll convince anyone here otherwise.

The operation of AMD and Nvidia GPUs is not very different, apart from some minor details which will be handled by the (now extremely cut-down) drivers, as well as availability of certain optional features like conservative rasterization or async compute
Mantle has to be generalized a bit to support all the platforms that it does, plus it will probably get some new features like bundles, but looking at D3D12, I can tell you that Vulkan will be like 95% the same
>>52289036
Vulkan hasn't been released yet, so it doesn't actually "work" with anything.
