polymer elements in rails - Geek-O-System

https://riesd.com/blog/2013/08/18/polymer-elements-in-rails

Polymer Elements in Rails. Recently for our local ruby meetup group. We had a frontend Battle Royale. The idea was to make a simplistic rails app that could serve as a starting point and then implement a frontend in several different ways (ember, angular, etc) so that we can compare the costs and benefits of these different techniques. We picked a comic book collection as the simplistic app. You can see the code. On the URUG github account. The README. Contains information on the desired UI. Maglev on AW...

Maglev on AWS t1.micro - Geek-O-System

https://riesd.com/blog/2014/02/16/maglev-on-aws-t1-dot-micro

Maglev on AWS t1.micro. TL/DR; If you want to run maglev on a small AWS instance you probably need to reduce the shared page cache size. Try adjusting the SHR PAGE CACHE SIZE KB setting in system.conf. Is really awesome and I want to make a few toy apps and host them on my t1.micro AWS instance. When I did a vanilla RVM install of maglev head I got a bunch of output that ended with this:. Startstone[Info]: Starting Stone repository monitor 'maglev'. Startstone[Error]: Stone process (id=12577) has died.

Puma runs on Maglev - Geek-O-System

https://riesd.com/blog/2014/02/26/puma-runs-on-maglev

Puma Runs on Maglev. Edit: After writing this I discovered that there was an problem with my GEM PATH environment variable so puma was actually running under MRI. No Wonder it was running at almost the exact same speed as MRI :) Sorry for the false information. In my last post I talked about debugging my problems when trying to get puma running under maglev. In just a few short days I’ve gotten help on the mailing list, at a users group and on the Maglev. But I can’t seem to post without some numbe...

Facial Recognition With Spyglass - Geek-O-System

https://riesd.com/blog/2014/04/25/facial-recognition-with-spyglass

Facial Recognition With Spyglass. The first step in working towards Friendly Bot. Is to get some code working that can capture an image from a webcam and detect a face in it. I knew that OpenCV. Had facilities for doing facial recognition, but I was hoping to avoid some of the documentation pain that I have heard about from other people. I did a quick search for rubygems that wrapped opencv and found spyglass. That got me started almost immediately. Haarcascade eye tree eyeglasses.xml. Make a webcam moun...

Planning Friendly Bot - Geek-O-System

https://riesd.com/blog/2014/04/23/planning-friendly-bot

In many ways Robotics was my first tech love. I remember my dad bringing home a broken printer from work and I took it apart and used the parts to make a little machine that had some LED eyes and drove itself forward and backward. It wasn’t really a robot, but it got me so interested in robotics that I started learning to program. I paid my way through university ( BYU. So I started thinking through all my old ideas and tried to find one that is:. Would make a 3yr old excited. I envisioned a robot that.

Controlling a Servo with Artoo - Geek-O-System

https://riesd.com/blog/2014/05/12/controlling-a-servo-with-artoo

Controlling a Servo With Artoo. Now that I have some basic facial recognition. Working we need to be able to control the direction of the camera. The first step to do this is to get some wires connected from my laptop to a servo and send signals that control the motion of the servo. Has a really simple interface for handling gpio like servos. In my case I used a digispark. To get access to some gpio pins that my laptop can control. Eventually I will use the Beagle Bone Black. According to the artoo docs.

PStore is Amazing - Geek-O-System

https://riesd.com/blog/2014/03/25/pstore-is-amazing

TL DR; Want to play with an object database? Skip Maglev and play with PStore. My last few posts have been about my adventures of trying to get Puma to run on Maglev. That adventure began because Johnny T. Infected my brain with the the idea of persistent objects. The idea that I could stop making applications in terms of relational tables and just create object graphs that can be persisted with ACID transactions. The City On a Hill. You might think that removing the Object-Relational Impedance Mismatch.
