MononcQc: May 29, 2007

I've recently been working on a dispatching application in Erlang that aims to work for high-performance, low-latency resource dispatching & pooling requirements. The lib is at https://github.com/ferd/dispcount, and this morning it made it in production for some of our Cassandra connection pools:

The most important point: we no longer see nearly as many timeouts, which is vital for our real time bidding business and being able to know when we will or won't be able to bid. Plus, in general we managed to get more performance out of the same database. The 'not_found' values are only misses, and getting many of them is as good as getting 'hits' performance-wise. Not shown on the graph: doubling the number of workers/connections giving even better results.

I'm pretty happy about it. A good way to begin the week.

Playing with canvas again. :getin:

Hand coded everything just for fun. It's hardly an efficient way of doing 3d stuff but it's pretty cool. For example, the 3d rotation is calculated like this:

code:

	function translate3d(p) {
		var x2 = p.x*Math.sin(this.rotation.z)-p.y*Math.cos(this.rotation.z);
		var y2 = p.x*Math.cos(this.rotation.z)+p.y*Math.sin(this.rotation.z);
		var x3 = x2*Math.sin(this.rotation.y)-p.z*Math.cos(this.rotation.y);
		var z2 = x2*Math.cos(this.rotation.y)+p.z*Math.sin(this.rotation.y);
		var y3 = y2*Math.sin(this.rotation.x)-z2*Math.cos(this.rotation.x);
		var z3 = y2*Math.cos(this.rotation.x)+z2*Math.sin(this.rotation.x);
		var x = x3/(2+z3/2)*0.85;
		var y = y3/(2+z3/2)*0.85;
		return {x:x,y:y,z:z3};
	}

Where p is the x y and z co-ordinates of a point. The z3 is stored to re-arrange an array of faces based on z value for the drawing order.

The poly itself is stored as a series of 3d co-ordinates based on the golden ratio, it's loving hideous. Eg, one of the faces:

code:

		var phi = ((Math.sqrt(5)+1)*0.5);
		out.face(0,[
			{x:s+ox,y:s+oy,z:s+oz},
			{x:phi+ox,y:0+oy,z:(s/phi)+oz},
			{x:s+ox,y:-s+oy,z:s+oz},
			{x:0+ox,y:(-s/phi)+oy,z:phi+oz},
			{x:0+ox,y:(s/phi)+oy,z:phi+oz},
			{x:s+ox,y:s+oy,z:s+oz}
		]);

S is the size, ox, oy and oz are offsets, etc.
It's a pretty versatile little setup, i've set it up with cubes and stuff. It's hardly efficient though and starts choking at about 20 or so faces with a bunch of rotation.

Oh and it's got some half assed click-drag rotation support that doesn't work right. :effort:

Yeah that's much more efficient than mine. I kinda built mine so I could do stupid stuff with it. My shading algorithm uses the same cripplingly inefficient add-as-you-go z values to do its thing as my z-sorting. I can do this though.

Been working on a dungeon crawler engine inspired by blending roguelikes with Ultima Underworld, to the end of making an iOS / Android game. The world is tile based with per tile ceiling and floor heights, which has made implementing AABB collision super simple and should also allow me to piece together randomly generated floors. Basic combat and pathfinding is in, I'm now mulling over whether to implement an inventory system or do things Hack/Slash/Loot style and just let you swap out items.

Looks interesting, I'll watch your progress.

I've just read through the README file, I can see why you might want to use a different serialisation format than JSON for this.

At work we use JSON extensively for our internal web api's and I'd be interested if you could expand a bit on the 'hosed up unicode' support in JSON as its not a problem I've hit, yet.

# ? Feb 25, 2012 11:51

tef: May 30, 2004; -> some l-system crap ->

json doesn't handle outside the bmp well.

quote:

To escape an extended character that is not in the Basic Multilingual
Plane, the character is represented as a twelve-character sequence,
encoding the UTF-16 surrogate pair. So, for example, a string
containing only the G clef character (U+1D11E) may be represented as
"\uD834\uDD1E".

the rfc also says things like this

quote:

Encoding considerations: 8bit if UTF-8; binary if UTF-16 or UTF-32

JSON may be represented using UTF-8, UTF-16, or UTF-32. When JSON
is written in UTF-8, JSON is 8bit compatible. When JSON is
written in UTF-16 or UTF-32, the binary content-transfer-encoding
must be used.

Edit: I wonder if in the future you could attempt to set up some form of system that plays separate piano together to achieve the sound of the chord currently on the screen. It'd only need as many sound files as there are notes, ie not many. Then again there's guitar too, plus coding it might be a bit difficult. But seriously, if you added that it'd be the actual best site on the internet in regard to these kinds of tools.

I found some old plans I made for a vacuum chamber and decided to model it and render it with my ray tracer. This is the exploded view, I didn't actually design it to require floating bolts.

I finally implemented explicit direct lighting as well. This was something I'd been avoiding for some time for stupid ideological reasons.

gently caress you for being so much more awesome than I.

Because nuts go around bolts. They serve different purposes.

Thanks guys. Just for giggles, I re-rendered the image overnight but with the chamber made of plexiglass.
