It's alliiiive! It's an assignment for a data structures class. I know it's not very exciting but this is the first real confirmation I've gotten in some time that my code works, aside from tracing algorithms and crunching numbers and tracing it on a paper grid to make sure what it was doing made sense. Next step is to get gnuplot to make it pretty for me. The numbers are rovers, and the Xes are obstructions. Rovers enter the world not knowing anythign but what they've seen, and have to explore and map the surface while trying to minimize terrain costs (they don't even know how big the world is so most of my headache has been keeping track of them using different systems on the inside and the outside and reconciling the two, so that the outside knows where the rover is in order to tell it what it can see). Underneath that is a randomly generated world like this, where the cost to move from any given cell to the next is determined by the relative heights:  The rovers don't know anything about each other yet, and when they step on each other currently Bad Things Happen. It appears in my screenshot that 4 has already been eaten. Rest in peace, rover 4. Ultimately they should sync their map data when they become adjacent but this isn't a requirement (though it may be a final exam thing and I've written what I have with that addition in mind). I've imagined a clever algorithm for doing it efficiently so I want to do it at some point. Also, gently caress the boost graph library's documentation forever Bonus animated gif of my terrain generator doing its thing on a 250x250 grid: http://i.minus.com/ibfCc5XFfKEUB2.gif (linked because it's big) I wish I knew how to animate stuff like this in realtime inside the program instead of having to deal with gnuplot.

 A small web app that will send you a notification if a band you like is coming to town. I found out that one of my favorite bands had been in town two weeks earlier.. they broke up several years later, without ever coming back.. this is something that's stuck in my mind since. Edit: It's up and running at http://concertsby.me

Spime Wrangler posted:drat, that's some sexy output. What kind of pathfinding are you using? e: the rover has to map the accessible surface, with costs and constraints related to slope as well as obstructions (the red checks), knowing only about cells it has been adjacent to It's just dijkstra from the BGL at the moment. It runs until it finds a shortest path to an unvisited vertex, then stops the algorithm and pushes that path into its command queue. Then it follows the command queue until it discovers a new unvisited vertex, either on the way or at its destination, at which point it dumps whatever's left in the queue and recalculates. I've been pondering how I might better implement the pathfinding but I'm already above and beyond what the assignment calls for and I really need to stop working on this and do linear algebra and physics stuff  I've never used the BGL or done pathfinding stuff or dealt with adjacency lists in actual code so aside from having to get my head around the awful, sadistic BGL documentation and generic witchcraft I've had fun slaving away over this thing. poverty goat fucked around with this message at 17:26 on Apr 17, 2012 |

Next you need to have the rovers build 'communications towers' when they reach the tallest point of land they're on. These could transmit map information to any other rover in line of sight

I continue to crack away at Marathon's map format in my spare time. I now render it using actual WebGL calls (gl.drawElements) rather than 2D canvas calls. Also, I can read the polygon type (water, platform, etc.) and respond accordingly. I'm incorrectly rendering secret doors, landscaped textured polys, and a few other things, but it's a solid first cut I think. I have the first cut at getting the lines in, but again, it's a first cut. I'm not properly ignoring lines between similar elevations, or the bolding the lines on the edge of the map.  Exploring all this is incredibly cool and rewarding. WebGL is surprisingly different than the version of OpenGL used in Aleph One which is forcing me to actually understand both the OpenGL and the WebGL. The fact that javascript isn't strongly typed is making the code considerably simpler -- that and I don't need to hack in support for different platforms or SDL.

Not a screenshot, but my website/tutorial on Erlang, Learn You Some Erlang has officially got its page to be published by No Starch Press as a dead tree book. Pretty happy about it, although I'm fighting a bit to get the book cover to look a bit more like the site. That will be the conclusion of roughly 4 years of hard work during weeknights and week-ends, very eager to hold a real copy in my hands

This is sort of a repost but I'm picking up this project again and would like to get some feedback on what kind of features would be helpful to implement. This video shows some of the changes I've made since the currently-released 0.15 version. https://www.youtube.com/watch?v=T26nQX1Pc6g To avoid clutter in this thread hit me up on IRC or on the Facebook page I just made for it.

I know this can be frowned upon, but other than buying the book through NoStarch press (Sept. 2012 and I'm a horrible cheap bastard) is there any other way to offer some voluntary compensation? I've been plowing through the book online and feel a little guilty about giving nothing back.

I've been plowing through the book online and feel a little guilty about giving nothing back. I've never set up a channel to receive money. This is because I always feared that I'd get people to donate who would then ask me to cover topic X and Y and be really persistent about it, waving donation money as if it had bought them a right to try and boss me around on stuff to write. I knew full well that I would be losing money putting stuff online, that people would be getting the information for free (this was in fact one of my main objectives). You don't have to pay me anything or compensate in any way. If you don't feel like paying No Starch for the book, just don't. I'm fine with it. Even publishing the book isn't something that I plan will bring much money. It is very likely that it will take a long time before I can say I wrote the book for even the minimum wage. I got my true compensation in terms of reputation and job offers with better salaries already, so really, no guilt to feel on your part.

It kind of speaks for itself. We'll be going into beta someday today, and it should soft-launch on Facebook sometimes soon after that. Right now, I'm in DB hell, since I have to hand-enter all of the sweater definitions with raw PHP. If it succeeds, I'll... you know, actually make a tool for this. For now, though: Ugh.

More work on this, most visibly region capture (with optional + default region select helper thing):  Minimalist but functional. Since the app doesn't have a single instance limitation yet, I used the region-selecting capability of instance #2 to take this.  Again, if anyone wants to try this out, just hit the link I quoted above. Also since last time I added Ctrl + Shift + PrintScreen which takes a great documentation quality screenshot of the current foreground window and directly uploads it to Imgur and copies the link to your clipboard. That functionality has been possible for quite awhile, but now it's in the default out of box configuration. If you're one of the four people who've already downloaded this app all you need to do to update is hit the 'Relaunch to update' menu item on the system tray icon, and it will (should!) silently bring you up to date. Streamlined, no-thought updates are a priority for this app (should be for all desktop apps) and so I'm pleased that that appears to be working.

I knew fuckall about web based programming when I started this. And now I know a little bit of Javascript and PHP. I scraped some info and created a database of 5000+ home addresses and the prices that they were evaluated at according to the national association of realtors. Then I used the google geocoding api to get their latitude and longitude values and store that in the DB. Now i display them in pink / red circles based on price. Also you can see schools. Foreclosures are the red balloons with links to their webpages. Only one zipcode and thousands of circles on a page chews up memory though. http://www.somethinglikecorkscrews.com/

Could you shade a street at the average price and only plot majorly different prices as dots? Save the fine plotting of each house value to a zoomed in view.

Been playing MUDs lately, and realised I only needed to tweak my roguelike engine a little bit to make text-based input easily done even as a main method of control. Ended up actually making my sample project for the engine use this by default, since it's easier to show off and test the extensibility of the engine with it!

Not much to see here visually, but I finished full code-coverage tests for the 6502 implementation I'm writing for an NES emulator. With the CPU pretty much done, time to dive in and start building the PPU. Writing the whole thing in Go (and planning to use SDL for the graphics/audio layer). I've written a handful of VM's in Go recently and really like it for that kind of task.

The PPU was never publicly documented so that will be a lot of reading up on reverse-engineered information and learning from what other folks have done as well (that's true for the APU as well).

I am a terrible, terrible Draw Something player, so rather than admit I can't figure out an obvious-in-hindsight drawing, on the bus yesterday I wrote a quick Python script that brute-forces all possible words of a certain length that could be spelled with the 12 supplied characters.
