How to get a local Cloud Foundry Instance?

I’m looking to learn about Cloud Foundry and I’m trying to get a development instance of it set up on my local Windows 10 PC. But I’m not having any luck.
I’m finding a lot of information about PCF Dev which was deprecated a while ago. I also looked at the replacement for PCF Dev, CF Dev (https://github.com/cloudfoundry-attic/cfdev). Its git page mentions that its repository is no longer receiving updates. I still went ahead and tried installing it using the instructions in the README:
cf install-plugin -r CF-Community cfdev
But the link it uses to download the plugin is broken:
Starting download of plugin binary from repository CF-Community...
Get "https://d3p1cc0zb2wjno.cloudfront.net/cfdev/cfdev-v0.0.18-rc.36-windows.exe": dial tcp: lookup d3p1cc0zb2wjno.cloudfront.net: no such host
Can anyone recommend a way to get a development instance of Cloud Foundry set up on my local machine so I can play around with it?
Thanks
Yes, steer clear of pcf-dev and cf-dev, they may still work but are definitely not getting updates so will be way out of date by now.
My understanding, although I haven't tried this process in a while, is that the way to run locally is with VirtualBox. You can run one locally using bosh-deployment & cf-deployment and Virtualbox.
For instructions installing Bosh in VirtualBox using bosh-deployment, see the Install Section to install Bosh.
With Bosh installed, follow the deployment guide to get CF installed. You can skip to step 4, since you're installing into VirtualBox. Be sure to read the entire document before you begin, however pay specific attention to this section which has specific instructions for running locally.

C++ on Jupyter Notebook for Windows

Has anyone successfully installed and used C++ on Jupyter Notebook on a windows machine? The installation instruction here never worked for me.
conda install -c conda-forge xeus-cling
gives me
"PackagesNotFoundError: The following packages are not available from current channels:"
If anyone has succeeded in installing on Windows, could you please share your instructions? Thanks.
The "issue" is that conda-forge/xeus-cling isn't available for Windows (yet?) (as indicated on this page of conda-forge/xeus-cling on anaconda.org). You can instead use gouarin/xeus-cling (you still have to have the compatible environment, though). Of course, the online C++ Jupyter Notebook is available too.

How do I update my h2o version on AWS working with flow?

I installed h2o using the AMI on the marketplace. It installed 3.14, and I am trying to update the version to the latest stable one of h2o.ai so my co-workers can use flow. How can I best do this?
I have tried uninstalling using
pip install http://h2o-release.s3.amazonaws.com/h2o/rel-wolpert/4/Python/h2o-3.18.0.4-py2.py3-none-any.whl
And directly by SSH-ing into my instance via terminal. However, even if it says "successfully uninstalled", it seems to keep reverting to the version 3.14.
I suspect there is a script at startup that is reinstalling and loading 3.14, but I can't figure it out. Any help is appreciated.

How do I go about installing ColdFusion 11 Trial on an Ubuntu 14.04?

I want to try changing my development environment from Windows 8 to Ubuntu so I would like to know if it is possible to install CF11 Trial on an Ubuntu? It will be my first time working with Linux. I already know how to install Postgre 9.3 and pgAdmin. I'm clueless with CF though. Can anyone help me?
Ubuntu 13.04 and 13.10 are supported with ColdFusion 11. Here is the list of supported environments. You can download CF11 here. For installation instructions, see: Installing the Server Configuration

Vagrant, VirtualBox built-in or no?

Trying to get set up with Vagrant but getting the error:
The "VBoxManage" command or one of its dependencies could not be found.
Please verify VirtualBox is properly installed. You can verify everything
is okay by running "VBoxManage --version" and verifying that the VirtualBox
version is outputted.
Just confused because the Vagrant documentation states:
"The getting started guide will use Vagrant with VirtualBox, since it is free, available on every major platform, and built-in to Vagrant."
Don't want to install VirtualBox separately if its supposed to be included when I installed Vagrant. Running OSX 10.8 if it's relevant, guessing I just need to install VirtualBox? If that's the case, what do they mean in the documentation when they say it's "built-in"?
Installing VirtualBox is required if you plan on using VirtualBox with Vagrant. I'm guessing they meant that the VirtualBox integration is built-in?
Recently, they've abstracted out the VirtualBox specific code and are working on allowing for multiple providers. I believe VMWare is now supported in addition to VirtualBox.
I had this message but my problem was different. I use Vmware_fusion as the provider. Vagrant was not able to detect what provider I am using.It assumed that I am using VirtualBox. Had this issue fixed by calling vagrant up provider flag. Here is the full command
vagrant up --provider vmware_fusion
