What I did today

#2161

Finally finished writing an ogg music decoder from scratch and have it hooked in to my openal player for streaming music

I know there is JOrbis out there that does the same thing but JOrbis is a complete line by line clone of an old libvorbis version and it is written in a very c like way (same variable names, same method names etc). It is also pretty complicated to get data out of it.

Partly for reasons of wanting to know more about the ogg vorbis format and partly for wanting a nice, simple and easy to use version I wrote my own version.

I started the project just by using the vorbis spec and used JOrbis/libvorbis as a debugging tool (Either the spec is not 100% accurate in some places, or libvorbis decided to do things differently!!), the only thing I copied from JOrbis was the inverse MDCT code (which was taken from libvorbis)

#2162

Implemented projectiles and weapon tiles. Been a long time since I have developed this.

I had to go put down my girlfriendā€™s dog yesterday which was my first direct face-on-face experience with death. It was quite definitely the most ā€œrealā€ moment Iā€™ve ever had in my life, nothing can prepare you for when you stare death in the face and finally understand how finite life truly is, and how cold and stone-walled death is. Later that night I also had a very spiritual moment where I felt connected to the Earth and to his soul. I canā€™t describe it, and I probably sound crazy, but I felt the Earth in that moment and the universe and the unknown.

Anyway, this isnā€™t high school and Iā€™m not writing a report. This is a programming forum, Iā€™m just fairly worked up over his passing because he was like family to me. Over the past almost two years heā€™s been there for some major changes in my life, both good and bad, and he was just almost comforting in a way to have there everyday. His death kind of symbolized an end of a period of my life for me, my life is much more stable now and now he is goneā€¦

R.I.P. Ralphie, I will miss you and I love you. You were an amazing friend and a great dog. Thank you for anyone who took the time to read this, I really needed to write something about it.

#2164

Held a lecture about the framework of my thesis at the Colloquium of our University.
Most of my fellow student know nothing about modern OpenGL :clue:

Thatā€™s sad to hear, you have my sympathy. :frowning:

#2165

Tell your girlfriend ā€œSome guy named DarkCart sends his regardsā€

#2166

Added stb bindings to LWJGL 3:

(will post details when the build is up)

#2167

Ahā€¦if youā€™ve include the voxel libraryā€¦that should make some people very very happy.

#2168

The voxel library is great, but thereā€™s no API to configure it; just a bunch of compile-time #defines. So you canā€™t really make bindings to it and keep everyone happy.

Also, I believe such high-level functionality is outside the scope of LWJGL.

#2169

Questions:

  • For what platforms will this be available?
  • Is this going to be built right into LWJGL3?

Because this looks awesome!

#2170

Itā€™s a small C library with no dependencies, so built-in and available on all platforms.

#2171

Awesome stuff, finally a decent AWT free solution for Java to read/write images and generate fonts on the fly.

#2172

Made some progress on my OS. Added a GDT and IDT almost successfully. Still some bugs to work outā€¦
But Iā€™ve got a working cross compiler, vga text, pretty good libc, and some other features :slight_smile: all in a week. Feeling good about this new project. I like OS development me thinks.

#2173

Finally got my cable thatā€™ll allow me to record guitars (as opposed to the vsts that just donā€™t sound as great without spending as much as an actual guitar costs). Played with that for an hour and a half. I need better amps, but I overall really enjoy the sound of it.

I also made this: https://soundcloud.com/literature-corner/the-beach
The levels and balance hasnā€™t been messed with too much, so itā€™s a bit off, but eh.

#2174

Canada Wide Science Fair was a bust, didnā€™t win anything, It was fun though! Iā€™ve been learning and programming neural networks for about 2 weeks now. Somehow a local summer science camp for teaching kids found me and shot me an interview. So on Saturday I will be going to my first job interview, for teaching PreK to Grade 6 how to program in Java, manage web-servers, and make robots with EV3 / NI-RoboIO platforms.

#2175

Reminds me of my first major science fairs, I did neural nets, albeit really basic stuff. Seemed to go over well with judges though, they probably didnā€™t expect that at an 8th grade gig.
You would like this, currently at the top of /r/programming: http://karpathy.github.io/2015/05/21/rnn-effectiveness/

#2176

So not really done today, but the last change on my project was that the Android-Implementation doesnā€™t force close any longer if it fails reading some user generated files :slight_smile: (and reading user generated files is like the one and only purpose of this app) - YAY

#2177

(I think this is becoming a problem)

In other news, I joined Reddit today :smiley:

#2178

DarkCart, run away from Reddit quickly. Seriously. Unless you want to be addicted to it like I am and go on it everyday for years and your work productivity nosedives!

If you do decide to stay then check out /r/programmerhumor, its really funny.

#2179 

private static void clean(File file) {
	if (file.isDirectory()) {
		for (File child : file.listFiles()) {
			clean(child); // with the holy water...
		}
	} else {
		file.delete();
	}
}

I find myself funnyā€¦ ;D

#2180

Bookmarked. :slight_smile:
RNNs always seemed very interesting to meā€¦ In every example of ANNs, they always avoided RNNs, and here they are doing awesome stuff like I thought they would.

Finally, for the decades LWJGL has existed, we now have a good font library. Seriously, awesome work you guys are doing.
