Breaking into Web Development

I work as an analyst contractor, these days my roles are often a mixture of development and management. I have been asked by a countless number of people what they need to do to get the jobs I’m offered – and it’s simpler than most expect. The market for talented developers in the United Kingdom (and in many talent-lite communities around the world) is such that anyone who merely knows what they are doing has a very good chance of getting a job. Even a job contracting (which ordinarily has senior-level requirements).

To become a web developer with a good salary and employment expectations you need skills. Below I’ll provide a plan to get you towards the top of the largest market: PHP Web Development. Advanced knowledge of everything on this list would immediately make you one of the best, so just strive to have an exposure if not a comprehensive understanding (though the *starred points are essential). To learn these technologies you should use several in combination on on

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

I have some early benchmark results for our work on a high performance NATS server in Go.

Quick Summary:
We can process ~2M msgs/sec through the system, and the ingress and egress are fairly well balanced.

The basics of the architecture are intelligent buffering and IO calls, fast hashing algorithms and subject distributor/routing, and a zero-allocation hand-written protocol parser.

In addition, I used quite a bit of inlining to avoid function overhead, no use of defer, and little to no object allocation within the fast path. I will share more details and the code at a future date.
