>>20609672
He didn't say "smart pointers". Pointers were implemented in pure C.

>>20609696
No I mean he's a bad programmer and retarded for thinking pointers aren't useful in C++.

>>20609697
It doesn't matter. Pointers are good, anyone who disagrees probably hasn't made anything more complex than a calculator.

>not making everything void*

>>20609711
Oh fuck you, where did I ever state I have something against pointers. Don't put words in my mouth.

I'm learning C++

Finding it difficult to come up with ideas for projects beyond the scope of making calculators or some other worthless shit, but experimenting and doing stuff on my own like this is the easiest way to learn

That's nice.

If it were me implementing it from scratch I'd start with the
http://en.wikipedia.org/wiki/Paley%E2%80%93Wiener_theorem
then find the eigs, perform a independent component analysis, then find the components with the highest kurtosis. It'd still be subject to the frequency leakage though as that paper mentioned. Same time complexity.

I do categorical image processing in biological like settings. Been falling in love with independent component analysis lately. You've got to implement from scratch with your own mutual information estimator because a lot of the code out there right now is garbage.

Wtf, why does switching increase your chances?

>>20609797
It just works, like Macs.

>>20609797
Because statistics.

>>20609797
pick 1/3 chance first time, 1/2 chance second

>>20609797
>Pick a door out of three randomly
Current chance your door is correct: 33.4% [66.7% chance it's one of the other two doors]
>One wrong door is eliminated
Current chance your door is correct: 33.4% [66.7% chance it's one of the other two doors]
>There's only 1 other door, and there's a 66.7% chance of one of the other doors being the correct door
Therefor, by switching you have a 66.7% chance of winning.

>>20609828
That's true but doesn't explain which switching is beneficial? It would be a 1/2 chance switching anyway

>>20609797
There's 2/3 chance you'll miss the first time. And since third door is eliminated, you are left with correct choice for switching.

>>20609828
>1/2 chance second
It's 2/3, not 1/2.

>>20609857
How?

The 3rd door is eliminated by opening surely?

I'm trying to get my Commodore 64 to do some moderately useful shit. I don't have an assembler, or a hex editor for that matter, so I'm basically hand-assembling hand-written assembly code into machine code and typing that shit in through BASIC.

>>20609866
BECAUSE FUCKING STATISTICS, THATS HOW THEY WORK. The 2/3 chance of winning by switching is PROVABLY correct.

>>20609866
Three doors, WLL.
You have 2/3 probability to pick L door.
Another L door is eliminated.
You switch to W.
You win.

>>20609866
>66.666%

You know, instead of using that awkward 5/9 and 9/5 shit, just use 0.555 and 1.8.

Well, ok, use 5/9 then, but there's no reason not to use 1.8.

>>20609933

>Don't know the basic as fuck monty hall problem.


Part 1: You have three doors and a car is behind one of them. You pick a door at random and theres a 33% chance to be a car.The other 66% you pick nothing.

Part 2: If you pick a door with nothing behind it, the host only has one choice of a door to open the door WITHOUT the car. Therefore 66% of the time the door he doesn't open is the door with the car. If you pick a door with the CAR behind it, he can pick either door and they'll both be empty and switching will net you nothing.

I may have explained that badly but its hard to explain it properly in one post.

>>20610059

How about: 66% of the time, the door he doesn't open will be the door that has the car. The other 33% of the time the door he doesn't open is one of the doors without the car

>may have explained that badly

>>20609961
The way I think about it is like this.
Assume that the prize was randomly assigned to p belongs to P. Alternately assume that P is a unordered set, (which can be sliced by magics).

P={1/3,1/3,1/3}
p=P[1]
P=relative_complement(P,p)
P={1/3,2/3}

You can show it's true a lot of ways. A easy way is to think about your initial choice and your switch choice. The initial choice has exactly a 1/3 chance. At this time the host has to choose between one of two scenarios.

1) You picked the prize.

2) You didn't pick the prize.

He's not going to show the prize, therefore he always reveals some likelihood about the current location of the prize. This is the key moment for the contestant.

You can easily simulate it with randns and keep a tally of your wins/losses.

I was never really good at explaining anything, anyways.

Code to read a 10bit analogue value from a microcontroller pin connected to a thermister and use it in an equation to calculate the temperature. It keeps returning 0x00 or 0x10, so i think the equation is off.

If you were wrong initially, you will be right if you switch.

I'm sure everyone can understand why that works, right? Good.

Your first choice will be wrong 66.7% of the time, when there are three doors.

Why the fuck do people still do this? Tradition?

>>20610497

Don't worry, you're not the only one who thinks this is terrible coding.

>>20610481
Python. Torrent books. Code something you find interesting. Read a lot of other's code on github.

Do this for 6 months -2 years, then learn another language like C. Then another language, like Haskell. Then Ada, Ruby, Asm, etc... All while coding useful things and reading on algorithm models.

>>20610481
Grab a copy of Visual studio express (it's free).

Google for tutorials on the language you want to use (C#).

>>20610472
Same. My last decent program is also for backup.
It's a frontend for duplicity and does:
- create read-only LVM snapshot of target partition
- mount it safely
- run duplicity, creating a compressed, encrypted, incremental backup, 1 full per month, 1 incr per day. keeps 60 days worth of data.
- umount everything, release snapshot

Most of the work was error and exception handling and good logging because this runs unsupervised on a server and fuckups with mounting or LVM snapshots could be fatal.

It's written in Python 3 and configurable with a YAML file.

>>20610515
What books to torrent?
>>20610516
so your saying start with c#?

>>20610481
Start with C#/Java and learn OOP. What are classes, methods, prototypes, interface, structs, private, protected, final, package private, ref, out. how does
public void function(int argument) { }
handle argument 'argument'? What is the difference between uint and int? long and longlong? Learn the syntax. Then make shit like quicksort, bucketsort, mkae your own (generic if C#, don't bother if Java) stack/linkedlist/list. Then make a simple application, like a calculator, using the stuff you already made.

http://thepiratebay.org/torrent/5534569/85_Python_programming_books_(May_2010)_(5_new)

The one I downloaded had 92 and was a few months off from this. It shouldn't matter. Read them until it all becomes obvious where they're going. Practice. Dragon book.

Some will introduce you to programming along the way. Some will just cut straight to how things work. Either way it will give you the language.

Watch MIT opencourseware Introduction to Algorithms. Implement them all in python. Next read up on some functional and object oriented algorithms and implement them.

Read code. Write code. Hack together little scripts that you find useful.

I really can't emphasize learning utility with it. You can use ipython as a cli shell and control every aspect and nearly every file type in your entire system through it with the power of python. Do this. I know maybe 6 languages well, but python is the hub of all my projects. C to a lesser, though important extent, but where I need speed. Miscellaneous others rarely. Though they're taught me a lot about programming and thinking about the problems.

I don't use C# or Java at work, but some of my friends and family do, and most of them have secret or top-secret security clearance.
Hell, my mother is a contractor for the government, and she has a 10 year NDA, and she works solely in Java.

I did not say otherwise. I am saying that mass appeal consumer applications are not a good indicator of "which languages are used".

I'm also saying that you've never been in the real world and literally can't even comprehend what a "business requirement" is.
