Also its multiplayer, using the UDP servers I made a while back. I still need to implement TCP for sending packets other than game updates though.

Also the terrain is destructible, forgot to add that.[/QUOTE]

You gonna open-source that? Also if it's uploaded anywhere, link plz

Pretty sure most of you don't know me but I've managed to land in twelfth place in the swedish "Programming Olympiad" ([url]http://progolymp.se/[/url]) which is a yearly contest for highschools in which you are to code 7 programs in order to solve problems, in 6 hours. This competition is held in whole sweden so woo!
This is also connected to the IOI (International Olympiad in Informatics) which is held in Australia this year, if you've managed to get to the swedish finals you can compete in a weekend competition where you have a chance to fight for sweden in the IOI, which means I have a chance getting to Australia!

Woo!

[Mr Kirill]

I've been working on a program for a trading company for over a month now, which has a large variety of features, such as multiple user types (operators, branches, admins), management of clients, goods, currencies, transports, branches, imports, orders, drafts, returns, invoices (with printing) and a lot of more minor functionalities. The whole thing is supposed to run in standalone applications in different offices and countries. All the program clients are connected to a single cloud server, which handles all the functionality and stores all the databases, synching all the branches together.

This is my most complex project to date! I know you like pictures but since I have to blur lots of info in the screenshots, the pic below is the best I can do. When a tab is selected, more tabs become available (there may be 2-3 rows of tabs visible at a time):

And now something different.

This is not exactly what I'm working on, but rather what I've stopped working on. Some of you might know that I've ran a blog for over 2.5 years where I published my own programming tutorials every day, I wrote about AS3, Flex, Air, Android and some more technologies. It's really sad but today I basically closed my blog with a [url="http://kirill-poletaev.blogspot.com/2013/03/hiatus.html"]final hiatus post[/url]. It was a long run and I learned a LOT of stuff during these years.

Here are some stats it has gained over the years:

985 posts
602,380 all-time hits
74 followers
650 comments
average daily pageviews: over 1000

On a bright side, I'll have time to work on new projects that won't require that much time dedication every day.

Been working on an application that helps users know some information when driving, it's all done with voice-recognition and crowdsourcing in mind. If I do continue I will probably add the ability to answer calls and messages too.

I've kind of fallen in love with [URL="http://questionablecontent.net/"]Questionable Content[/URL], but I wanted a simpler way to go to the next comic, so I decided to make a ruby script that'd download the images, and then I'll put them into a PDF.
And now I'm in love with Ruby. I thought that Ruby was a little simple, and that I couldn't really use it for anything, but here I am.

But for some reason, it keeps stopping at random times, which is kinda annoying.

require "open-uri"

puts "Enter start comic: "
start_comic = Integer(gets.chomp)
puts "Enter end comic: "
end_comic = Integer(gets.chomp)
for i in start_comic..end_comic  
  puts "Downloading #{i}.png"
  open("http://questionablecontent.net/comics/#{i}.png"){|f| 
    File.open("#{i}.png", "wb") do |file| 
      file.puts f.read
    end
  }

end

Cool concept and app, though the grammar in the video bothers me a little (I get the accent, but you missed a word somewhere in there with the text), and the audio is a little loud, and I feel like it could startle me while I'm driving or something. (it actually kinda startled me a couple times while watching that video)

Change Integer(gets.chomp) to gets.chomp.to_i, it's more Ruby-like that way

Thanks for the feedback! I completely agree with you, to give more of a backstory, this was done for a competition and as usual with these things I spent most of the time worrying about the app itself than the video which left it a little bit rushed, but this shouldn't be an excuse. You can control how loud you want the voice to be in app though.

Really just gets.to_i, String#to_i already ignores surrounding whitespace.

[redx475]

Finished adding constant table support to my vm's compiler. I need to make it also always use the same endian, but I'll deal with that later.

Here is a useless program:

ctable "nope"
ctable "yep"

thisisalabel:
  push 9
  push 3
  push 88
  push 0
  push "Hello World!"
  push true
  push false
  goto thisisalabel

The compiler takes all non-integer pushes, adds the constants to the constant table if needed, then replaces them with loadk (load from constant table onto stack). ctable just manually adds constants to the table (the compiler doesn't care where you put ctable, though the order of the ctable statements matter).

It gets compiled into this:

[t]http://i.imgur.com/KaKBQBj.png[/t]

The current format for my binary is as follows (in C-like pseudocode):

// Header
char[3] identifier = "SVM"
uint32 version // Version of the compiler, right now it is 2
uint32 ctable_count // Number of entries in the constant table
// Then come all of the constants in order. Each type is stored differently

// Constant - nil/null
uint8 type = Shogun::Data::NIL

// Constant - integer
uint8 type = Shogun::Data::INTEGER
int32 data

// Constant - boolean
uint8 type = Shogun::Data::BOOLEAN
uint8 data

// Constant - string
uint8 type = Shogun::Data::STRING
uint32 length // Including NULL-terminator
char[len] data

// Then comes the opcodes
uint8 opcode
int32 argument1 ... argumentN // If there are any arguments at all

I haven't had a chance (or the patience) to fully check the binary to see if everything is correct, but I did check at least the header and constant tables (though there is some weirdness in the size of each field - i need to check that).

The issue is not with cli, the command line requires sudo to change the date and time. The issue is with desktop environments not requiring it when done through the UI.

I took a week off from my space game project to fiddle around with an AOE2 clone again. Red Rect = Debug View Rect, Blue = Culling Rect

I have simple terrain rendering/batching/culling going on, a bit of a simulation backend with fixed math to ensure it runs correctly on different computers. I also imported the data system I'm using for my other game to save some time.

I just don't get integer promotion rules with the unary ~ and -

[cpp]unsigned long long i = ~(unsigned char)1; // Promoted to 1ULL before doing binary negation and assignment
unsigned long long i = ~1UL; // NOT promoted to 1ULL before doing negation (as far as the standard is concerned, I think it should)

unsigned int tmp = 1;
unsigned long long i = ~(unsigned char)tmp; // Promoted to 1ULL before doing negation
unsigned long long i = ~(unsigned short)tmp; // Promoted to 1ULL before doing negation...
unsigned long long i = ~(unsigned int)tmp; // Surprise! Not promoted to 1ULL before negation.
unsigned long long i = ~tmp; // Not promoted.[/cpp]

When passed to functions, however, it gets promotions like it should

[cpp]void func(unsigned long long x);

func(~(unsigned int)1); // Surprise again! This time it gets promoted to 1ULL before negation[/cpp]

This behaviour is in GCC and MSVC

Bonus:

[cpp]// Bob has 18 quintillion apples
unsigned long long bob = ~(unsigned char)1; // 18446744073709551614

// He gives 4 billion of them to Alice
unsigned long long alice = ~(unsigned int)1; // 4294967294

// How many apples is Bob left with?
unsigned long long bobn = ~(unsigned char)1 - ~(unsigned int)1;[/cpp]

[sp]Bob is left with 0 apples![/sp]

Ecma-334(C#) has information on the craziness of numeric promotions. Even though its C# it should be very similar to C++.

Been exploring how steam stores data and stuff. Checked into bioshock infinite, apparently the game is uploaded to the steams servers, has a 953.7 MB steam cloud storage availability, the install script installs direct x, vc redist 08, vc redist 10, and d3d11 install, it has these languages: "languages" "english,french,italian,german,spanish,japanese,brazilian", it's definitely singleplayer, has a lot of dlc: "ListOfDLC" "214930,214931,214932,214933,214934,214935,214936,214937,214938,220140,224090",

I was in the qualifying round some years ago and passed to the final, but that clashed with other stuff, so I never participated. I was going to try again the next year, but that never happened. :v:

I've been working on a game called Vanity, which is a top-down arcade shooter that is supposed to be so fast paced you don't know what the hell is happening, or something like that.

The music was made by a friend of mine named Pitfall, who had most of the music made before the game was even created!

I've got the game and the latest version on [url="http://www.indiedb.com/games/vanity"]IndieDB[/url] and [url="http://gamejolt.com/games/arcade/vanity/12625/"]GameJolt[/url], but I will most likely sell the game on Desura and Steam once it is finished.

And now I got the whole weekend to work on it. Yay!

You shouldn't be changing the date and time, unless you're the sysadmin (root). The only exception to this is adjusting the user's time zone, which shouldn't matter since Unix stores dates as UTC then adds the time zone on. I have no idea if that's per-user, though...

They're all physically simulated circles, works really well. Also I added throwing and picking up weapons like Hotline Miami

I found a use for the scary java:

Turns any window--into an 8bit music generator! [URL="http://filesmelt.com/dl/musical_chairs.7z"]musical_chairs.7z[/URL]
(Only works on windows machines, to open the overlay press shift+tab)
Good examples:

This is extremely cool (the program itself, and how advanced these have gotten)

[Map in a box]

Took only 3 hours getting the overlay to work properly(it's just a window over another window) and like 30 minutes to get the music part(i already have a library for it :v:).
But yeah it's insane how far they've gotten. Given time, I wonder if there will be a music generator.

Found this old snippet from an old thread that enumerates all the possible capitalizations of a given string.

[QUOTE=swift and shift]

import Data.Char
import Data.Function

caps [] = [[]]
caps (x:xs) = on (++) (flip map $ caps xs) (toLower x :) (toUpper x :)

main = print $ caps "waywo"

[/QUOTE]

Decided to rewrite it a bit shorter:

import Control.Applicative
import Data.Char

caps = mapM $ (<*>) [toLower, toUpper] . pure

main = print $ caps "waywo"
