I'd like to try OpenCPU in my own server. Official Installation Manual linked from https://public.opencpu.org/pages/download.html is not found.
Where can I get install instruction?

The new version of OpenCPU, which hasn't officially been released yet, runs locally as well:
library(devtools);
install_github("opencpu", "jeroenooms")
library(opencpu)
Note that you need a recent version of httpuv.
For now you can also have a look at the API doc, the opencpu.js javascript library and the cloud server.

I need to install Rtools in order to work with keras package. I've successfully downloaded Rtools from https://cran.r-project.org/bin/windows/Rtools/, but then I need to "put it on a path", as it is stated here on this website. I don't understand what is written here about doing that. Could you,please, explain it to me in a simple way and, desirably, with an example?
Thank you for your help.
The path is the list of all directories the operating system is going to look to find a program when you call it.
An alternative instead of modifying the system path, is to create a file which tells R where to find RTools.
As stated in the installation doc, just open an R console and execute once:
writeLines('PATH="${RTOOLS40_HOME}\\usr\\bin;${PATH}"', con = "~/.Renviron")

why is there not a url such as :
https://console.firebase.google.com/u/0/project/axel-02/database/firestore/data~2Fusers
but for local developement. It would be for example :
https://localhost:9000/console.firebase.google.com/u/0/project/axel-02/database/firestore/data~2Fusers
I mean, the data viewer is usefull... but it s a pain that it does work with the emulator in local dev.
You can use the following third-party tool: https://github.com/ablehq/firestore-explorer.
The emulator suite is a pretty recent release, and there's a long list of features that would make it more useful.
If you think the product would benefit from having such an explorer built in, file a feature request with Firebase support or on the Github repo of the project.

What does 0-cloud mirror stands for in R 3.x.x ? Just after installation R 3.0.1 I spotted that there is new mirror called "0-cloud" what is it ? I can't google it, I suppose that appeared just in 3.0.1 version.
It is a content-delivery network (CDN) created by RStudio to provide "local" CRAN mirrors. CDNs essentially bring mirroring to "the edge of your network". Think Akamai hosted by or near your particular ISP. The Wikipedia article I linked to has more.
I always presumed the name was mostly chosen to sort highest...

I'm trying to get some code off of google code and the message given is:
Non-members may check out a read-only working copy anonymously over
HTTP.
svn checkout http://ims-dev.googlecode.com/svn/trunk/ims-dev-read-only
How would I "copy anonymously over HTTP"? If it matters, I have a Mac.

svn checkout http://ims-dev.googlecode.com/svn/trunk/ims-dev-read-only
