Hey ---, nice to talk with you yesterday! Giant email ahead!

Here's what we talked about:

All open source projects use version control tools like git for code submission. Mozilla uses two version control tools (hg and git) to track the history of code changes: hg (also called mercurial) is used for Firefox code, git is used for other supporting projects. The underlying concepts for hg and git are similar, but I think the documentation for git is much better so I suggest you focus on git first. Github is a web-based user interface for git. Locally (i.e. "on your computer"), you will interact with git using the terminal instead by entering commands. Version control is all about tracking project history so that it's easy to merge work from many different people or go back in time; it's an extra step/tool in software development on top of writing/testing your code.

To start working on any open source project, the first step is to get a copy of the source code repository (e.g. git clone). Then the programmer ch

1. Clone your fork:

git clone git@github.com:YOUR-USERNAME/YOUR-FORKED-REPO.git

2. Add remote from original repository in your forked repository:

cd into/cloned/fork-repo
git remote add upstream git://github.com/ORIGINAL-DEV-USERNAME/REPO-YOU-FORKED-FROM.git
git fetch upstream

Story: Writing Scripts with Go

This is a story about how I tried to use Go for scripting. In this story, I’ll discuss the need for a Go script, how we would expect it to behave and the possible implementations; During the discussion I’ll deep dive to scripts, shells, and shebangs. Finally, we’ll discuss solutions that will make Go scripts work.

Why Go is good for scripting?

While python and bash are popular scripting languages, C, C++ and Java are not used for scripts at all, and some languages are somewhere in between.

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

The situation

Searching can be an efficient way to navigate the current buffer.

The first search commands we learn are usually / and ?. These are seriously cool, especially with the incsearch option enabled which lets us keep typing to refine our search pattern. / and ? really shine when all we want is to jump to something we already have our eyeballs on but they are not fit for every situation:

• when we want to search something that's not directly there, those two commands can make us loose context very quickly,
• when we need to compare the matches.

A better way
