Code used to obtain these results can be found at the url https://github.com/joschu/modular_rl, commit 50cdfdf375e69d86e3db6eb2ad0218ea6aebf371. The command line expression used for all the environments can be found in the text file below. Note that the same exact parameters and policies were used for all tasks, except for timesteps_per_batch, which was varied based on the difficulty of the task. The important parameters are:

• gamma=0.995: discount
• lam=0.97: see GAE paper for explanation
• agent=TrpoAgent: name of the class, which specifies policy and value function architecture. In this case, we used two hidden layers of size 64, with tanh activations
• cg_damping: multiple of the identity added for conjugate gradient

ruby-1.9.3-p327 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.

Requirements

• rbenv
• ruby-build

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.

2015-01-29 Unofficial Relay FAQ

Compilation of questions and answers about Relay from React.js Conf.

Disclaimer: I work on Relay at Facebook. Relay is a complex system on which we're iterating aggressively. I'll do my best here to provide accurate, useful answers, but the details are subject to change. I may also be wrong. Feedback and additional questions are welcome.

What is Relay?

Relay is a new framework from Facebook that provides data-fetching functionality for React applications. It was announced at React.js Conf (January 2015).

Option 1: Via macOS environment variable:

1. mkdir -p ~/Library/LaunchAgents
2. Put tlskeylogger.plist at ~/Library/LaunchAgents/tlskeylogger.plist
3. launchctl load ~/Library/LaunchAgents/tlskeylogger.plist, so it will load on the next restart
4. launchctl start ~/Library/LaunchAgents/tlskeylogger.plist, so it will load the environment variable immediately
5. Restart your browser(s)
6. See how TLS keys are being written to ~/.tlskeyfile via tail -f ~/.tlskeyfile

NB: This may be hit or miss and many apps do not respect the env var.

Internet Scale Services Checklist

A checklist for designing and developing internet scale services, inspired by James Hamilton's 2007 paper "On Desgining and Deploying Internet-Scale Services."

• http://mvdirona.com/jrh/talksandpapers/jamesrh_lisa.pdf

Basic tenets

• Does the design expect failures to happen regularly and handle them gracefully?
• Have we kept things as simple as possible?
