April 2014

April 8th, 2014 by Mark Luffel

Another hack report! We remember to post updates sometimes! Tonight is a night that we remembered to post to the blog. Here it goes:
– Installing GameMaker
– Going through tutorial on low-poly game art: “How to make cool stuff in Unity
– Low-poly game art in SketchUp
– Found that tutorial that Rob’s going through
– Updating her website to include design work (not just photography)
– Minimum spanning trees in Processing this weekend
– Texture synthesis via randomized graph traversal in Mathematica (as in “Painting by Features“)
– Recently: GStreamer to capture slit-scans of trains moving past his apartment
– Cocos3D for viewing photos

Puzzlescript and NaNoGenMo hack

November 5th, 2013 by Mark Luffel

We haven’t posted in a while, but we’re still hacking!

Tonight was Jordan, Rob, Mark. Vinny has been joining us regularly too.

Recently we’ve been doodling, reading The Baffler, writing Puzzlescript, plotting for NaNoGenMo, making comparatr and incomparatr, playing at Nophest 2013 as Blanca Noche, writing a scripts for a communal streaming music server, resurrecting the Atlhack server.

We had a visitor, Kiril, who knows Atlhackers (Mark, Vinny, and Karthik) via David Stolarsky (because they went to UIUC together. Kiril writes code at Weather Channel, and previous collected behavioral data at Yerkes Primate Center.

hang out and chat hack!

June 12th, 2013 by alexr

Tuesday night!

Participants: Mark, Alex, Vinny

Topics discussed:
– languages and the future thereof
North Sentinel Island
– business plans
– starting a bar called The Trading Floor, where prices on beer floats based on market forces. For extra credit, make it so that bar patrons can also sell beer, and you have to run around all furious, wearing a suit and shouting into a phone about how buying and selling should happen. There need to be futures on beer, and it needs to be possible to go short on it. Maybe somebody will ring a bell loudly.
– copyright and the future thereof (or lack of a future thereof)
– places and traveling to them
– funding for research
– getting stuff fabricated for hardware prototypes
– Atlanta startup situations
souls and their relationships with mathematics
– Paraguay and its history
– Graham Keith Coleman
– the ATLHack IRC channel on freenode and how people on it don’t seem to be on the facebook community? is there a facebook community? I thought we had a googlegroup or something… but not a circle. Maybe there’s a circle? Maan, I don’t know. But I love all of you and I wish I got to see you more often and I kind of want to move back to Atlanta but atlhackers are worldwide now anyway <3

Packaging for Deployment Hack

– Graduated Georgia State ’08
– worked at Inovalon, a nice place
– Tonight: Working on his .vimrc
– will upload to github
– Emily is just hanging out

– adding lua functions is easy
– their svn contains an iOS skeleton app
– has a scene editor, live reloading of lua scripts
– took an internet break this weekend, sketched out ideas for his game (in the “finger-racer” genre)

Atlanta 8 Jan meeting, Octane

* Since Last Week

** Graham
*** Fixed some bugs in mosaicing code, found others.
*** Mark helped compile unaudicle for Mac, it basically works.
*** Also helped me find some bugs, put them in my org-mode bugtracker.
*** Vinny showed me how to use org-mode’s time tracking C-x C-c [C-i, C-o]
*** C-c C-x C-j takes you to current clocked item.

** Rob
** Jordan
*** they are entering Killscreen and ouya CREATE competition
(24 Jan deadline!)
*** settled on the platform and have a plan of attack.

** David
*** went to Israel.

** Vinny
*** changing coworking spaces from Strongbox to Atl Tech Village.

** Karthik
*** isosurface extraction, and some nonlinear least squares, in python
using marching squares (for shape deformation, for a new project).
*** found multiprocessing python, probably better than threading.

** Mark
*** worked on upper body in Tango interface.
*** found a human population map for whoblinked.org

* This Week’s Plan

** Graham
*** Try to get supercollider accepting code over OSC.

** Rob
*** get controller input working.

** Jordan
*** Install Unity and play around with it.

** David
*** working on an iphone app.

** Vinny
*** working with collections in backbone-js (client side js)

** Karthik
*** create an animated sequence from slices.

** Mark
*** model your tango database and synthesize a dance.

* This Week’s Reality

** Graham
*** got a basic OSC shell that executes a working supercollider file.
*** looking for a way to safely compile bad code. looking into try/protect

** Rob
*** has a joystick-controlled vomit guy.

** Jordan
*** made a triangle move and read about metaball – a way to fake fluids.

** Vinny
*** has listItem rendering, but no appropriate data to render.

** David
*** switch statement.

** Karthik
*** extracted slices and wants to run some tests on them for patho cases.

** Mark
*** wrote a class that impl. histograms + main loop of synth +
drank a beer + talked to Hamza about genetic memory.
