Best Golang IDE: IntelliJ and VSCode

I've been using IntelliJ + go-lang-idea-plugin for years now (because it's currently the best one for almost everything: Ruby, PHP, Python, Javascript, SQL, you name it..), previously it's ok to use SublimeText + GoSublime, or LiteIDE, but today we got another completely working alternative that is also purely free (like IntelliJ Community): VisualStudioCode + lukehoban.Go. Here's how to install in ArchLinux:

yaourt --needed --noconfirm -S --force visual-studio-code 
go get -u -v github.com/nsf/gocode      
go get -u -v github.com/rogpeppe/godef
go get -u -v github.com/golang/lint/golint
go get -u -v github.com/lukehoban/go-outline
go get -u -v sourcegraph.com/sqs/goreturns
go get -u -v golang.org/x/tools/cmd/gorename
go get -u -v github.com/tpng/gopkgs
go get -u -v github.com/newhook/go-symbols
go get -u -v golang.org/x/tools/cmd/guru
go get -u -v github.com/cweill/gotests/...
code

Then press Ctrl+Shift+P, type "Install Extension", type: "Go", done :3

Everything's works fine now:

In my opinion, IntelliJ still the best, but surely I'll be using VSCode when my IntellJ license ends.

Techempower Framework Benchmark Round 13

After long wait, the latest Techempower Framework Benchmark 13 is out! And just like previous one, Go's fasthttp really really fast. As usual the most important thing is data updates benchmark:

Top ranker in this part (more than 1024 req/s) are Go, C++, Java, Javascript (NodeJS), Perl, C#, Elixir, Dart, Scala, Python, Clojure, and Groovy (Actually PHP are there below the last one on the picture with 1018 req/s). And for the database part would be: PostgreSQL, MongoDB, and MySQL.

Javascript Virtual DOM Framework Benchmark

Recently I found a framework benchmark for javascript (round4 2016-09-12), it shows a lot information. The fastest ranker are:

Framework	Version	Runtime Ratio (% slower than fastest)	MB Start	MB 1K rows
vanillajs		1	2.98	4.85
inferno	1.0.0-beta9	3	3.19	6.60
vanillajs-keyed		4	2.98	4.81
dio.js	3.0.5	4	3.19	7.09
domvm	2.0.0-beta	10	3.15	7.43
kivi	1.0.0-rc2	17	3.17	6.69

Also there are another benchmark (this have fewer framework, last result at this time):

Apparently there are a lot of them around the internet.

Of course you can build your own framework, here's the tips if you plan doing so.
