Simplex for Ruby - Daniel Lucraft
http://danlucraft.com/blog/2013/12/ann-simplex-for-ruby
I’ve released a pure-Ruby implementation of the Simplex algorithm. For solving linear problems. It may be useful to you if you can only run Ruby, or if you want to learn about the Simplex algorithm from a simple implementation. I really really didn’t want to write my own LP solver implementation. If someone else told me they had done this, I would smirk. It’s a notoriously hard algorithm to implement correctly. Have you tried compiling them on Heroku. For Ruby 2.0. Max x y 2x y = 4 x 2y = 3 x, y = 0.

Learning about Redis through writing a Twitter clone - Daniel Lucraft
http://danlucraft.com/blog/2009/05/learning-about-redis-through-writing-a-twitter-clone
Learning about Redis through writing a Twitter clone. Is a fast key-value database by Salvatore Sanfilippo. With some new ideas. Sometimes it’s called a ‘data-structures database’ because it supports sets and lists. I spent a few hours this morning writing a Twitter clone that uses Redis as its datastore, which is now online at http:/ retwisrb.danlucraft.com. The code is available on Github. Requires list traversal by Redis. Would they be useful? Anyway, I encourage you to try Redis out soon.

http://danlucraft.com/blog/2011/03/built-in-profiler-in-jruby-1.6
How to use the new JRuby profiler. The JRuby team released version 1.6. Yesterday, with lots of improvements and fixes. My contribution was extending the profiler with a graph mode and a Ruby API (with a lot of help from Headius. This profiler is built-in to the JRuby interpreter, no installation necessary! JRuby 1.5 included the. Option, which profiles all Ruby code run during the JRuby execution and outputs a flat profile:. In 160 there is now an additional profiling flag. How to profile blocks of code.

And do some other stuff too, sometimes. Terraframe: Making HashiCorp’s Terraform Awesome. January 10, 2015 — 5:04 AM UTC. Is a cool infrastructure-as-code system with a boatload of functionality. It makes building out entire clouds on AWS. Super easy and super fun. I am a fan. I started my new job as Lead Platform Engineer at Leaf. And I was really happy to have the chance to use Terraform in a greenfield project where I could play with it. But I wasn’t happy with it, and so I’ve done a thing. Doing this...

App ID struggle | App Mecha
https://appmecha.wordpress.com/2009/10/24/app-id-struggle
A focus on Web applications, in particular Google App Engine. I just tried for 10 minutes to get an unused application identifier that would make sense for the new example app. Adding insult to injury, every single supposedly taken ID I tried to access via the appID .appspot.com URL was a 404. Perhaps there is a bit of squatting going on? Yeah you can map to domain name, but it makes writing tutorials that much more of a pain😉. Designing cu3w0rx →. 3 Responses to “App ID struggle”.

Platform Poll Results | App Mecha
https://appmecha.wordpress.com/2008/11/14/platform-poll-results
A focus on Web applications, in particular Google App Engine. So we got a whopping total of 9 votes (and one “other” that gave no alternate answer). Predictably the top answer was Java (60%) with Ruby running second (30%) . On the surface this makes sense, since there is a well-established developer community and Google itself uses Java for a lot of their projects.
