+I like to play around with lots of different programming languages, but install too many and they pollute your working environment, so it's better to have them installed as a user instead of root. 
+Here's a way to get several of them installed into your unix user directory. 
+If things go wrong, or you get bored you can easily `rm -rf` the installation.

+To start using RVM you need to run `source /etc/profile.d/rvm.sh` or re-login to re-load `~/.profile`
+
+From here you can run - `rvm list known` and you'll see a list of ruby flavors and individual versions. 
+
+```bash
+# MRI Rubies
+[ruby-]1.8.6[-p420]

+[ruby-]2.6[.0]
+```
+
+MRI Ruby is the reference version of Ruby so let's install the latest version.
+
+`rvm install ruby-2.6.0`
+
+I'm running debian and rvm might ask for your root password to install some prerequsites from apt before compiling a new version. 
+
+Congrats, you now have a ruby install 
+
+```shell
+$ ruby -v
+ruby 2.6.0p0 (2018-12-25 revision 66547) [x86_64-linux]
+```
+
+from here you can now do whatever since I'm blogging this using jekyll
+
+`gem install bundler jekyll`
+
+
+# go
+Go is a language that releases new versions on a regular basis. 
+There's a similar tool to rvm called gvm. It's a "go version manager" available from here `https://github.com/moovweb/gvm` that'll let you install multiple versions and set $GOPATH and $GOROOT.
+
+
+as a regular user:
+```shell
+$ bash < <(curl -s -S -L https://raw.githubusercontent.com/moovweb/gvm/master/binscripts/gvm-installer)
+Cloning from https://github.com/moovweb/gvm.git to /root/.gvm
+No existing Go versions detected
+Installed GVM v1.0.22
+
+Please restart your terminal session or to get started right away run
+ `source /root/.gvm/scripts/gvm`
+```
+
+ you should be able to run and see 
+```shell
+$ gvm version
+Go Version Manager v1.0.22 installed at /home/john/.gvm
+```
+
+Run `gvm listall`
+which will give you a list of all the available versions of go.
+
+```shell
+$gvm listall
+
+gvm gos (available)
+
+   go1
+   go1.0.1
+   ...
+   go1.11rc1
+   go1.11rc2
+   go1.11.1
+   go1.11.2
+   go1.11.3
+   go1.11.4
+   go1.12beta1
+   go1.12beta2
+```
+of which there are entirely too many. 
+
+From here, we can install go as our user via binary here: 
+
+`gvm install go1.4 -B`
+
+try it out
+```bash
+$ go version
+go version go1.4 linux/amd64
+```
+We can see it gets installed here:
+```bash
+$ echo $GOROOT
+/home/john/.gvm/gos/go1.4
+```
+
+From the gvm link earlier, in order to compile a go build environment for versions 1.5 on we require another go build environment. 
+Go compiles itself! Neat huh?
+
+As of now the latest version is go1.11.4
+```bash
+$ export GOROOT_BOOTSTRAP=$GOROOT
+$ gvm install go1.11.4
+```
 
 ```bash
+$ go version
+go version go1.4 linux/amd64
+```
+you can run
+`gvm use        - select a go version to use (--default to set permanently)`
+
+```shell
+$ gvm use go1.11.4 --default
+Now using version go1.11.4
+$ go version
+go version go1.11.4 linux/amd64
+$ echo $GOROOT
+/home/john/.gvm/gos/go1.11.4
+$ echo $GOPATH
+/home/john/.gvm/pkgsets/go1.11.4/global
+$ ls /home/john/.gvm/gos/go1.11.4
+AUTHORS  CONTRIBUTING.md  CONTRIBUTORS  LICENSE  PATENTS  README.md  VERSION  api  bin  doc  favicon.ico  lib  manifest  misc  pkg  robots.txt  src  test
+ls $GOPATH
+overlay  pkg  src
+```
+
+Be sure to set --default so you keep the same version when you relaunch the shell, so that whatever you install stays where you expect it. 
+
+# node js
+node.js, the server side javascript framework
+
+nvm is Node Version Manager. Install it like this:
+`curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash`
+
+
+Since there are major revisions to the javascript language between node 4, 6, 8 I've found I've had to switch more often between these versions according to project than I did with other languages.
 
-rvm list known
+You can run `nvm ls-remote` and get a list of all the node versions available
 
+
+```
+$ nvm
+Example:
+  nvm install 8.0.0                     Install a specific version number
+  nvm use 8.0                           Use the latest available 8.0.x release
+  nvm run 6.10.3 app.js                 Run app.js using node 6.10.3
+  nvm exec 4.8.3 node app.js            Run `node app.js` with the PATH pointing to node 4.8.3
+  nvm alias default 8.1.0               Set default node version on a shell
+  nvm alias default node                Always default to the latest available node version on a shell
 ```
 
+so if you run 
+
+```bash
+$ nvm install 10
+Downloading and installing node v10.15.0...
+Downloading https://nodejs.org/dist/v10.15.0/node-v10.15.0-linux-x64.tar.gz...
+######################################################################## 100.0%
+Computing checksum with sha256sum
+Checksums matched!
+Now using node v10.15.0 (npm v6.4.1)
+Creating default alias: default -> 10 (-> v10.15.0)
+
+$ whereis node
+node: /home/john/.nvm/versions/node/v10.15.0/bin/node
+```
+
+and you can set it to be the default so the setting persists between sessions
+```
+nvm alias default 10
+```
 
-* To start using RVM you need to run `source /etc/profile.d/rvm.sh`
