This is a list of companies that I know of and want to share with others. As undergrads or early career devs we are not even aware of the various opportunities that exist out there. You mostly here about large companies like FAANG or really old and established ones like IBM or mass recruiting consultancies like Accenture or some popular mid-large scale startups that usually end up being a ride hailing or food delivery service.

But other companies with diverse fields of work exists out there, they can be of different sizes, they could be working on OS development and systems programming instead of building the next "unicorn" app. Be it dev tools companies or companies that pay you to work on open source projects I will try to compile as many as I know.

Benchmarking Nginx with Go

There are a lot of ways to serve a Go HTTP application. The best choices depend on each use case. Currently nginx looks to be the standard web server for every new project even though there are other great web servers as well. However, how much is the overhead of serving a Go application behind an nginx server? Do we need some nginx features (vhosts, load balancing, cache, etc) or can you serve directly from Go? If you need nginx, what is the fastest connection mechanism? This are the kind of questions I'm intended to answer here. The purpose of this benchmark is not to tell that Go is faster or slower than nginx. That would be stupid.

So, these are the different settings we are going to compare:

• Go HTTP standalone (as the control group)
• Nginx proxy to Go HTTP
• Nginx fastcgi to Go TCP FastCGI
• Nginx fastcgi to Go Unix Socket FastCGI
