Recently I wanted to install an application on a Mac, but it required an old version of R (3.2). On Linux and Windows, that is easy, since you install the application on its own path. Now, on a Mac, you can do it as well, but it will require extra work if you build it from source. There is something better!!! Here I outline what you can do easily…
Note that this illustration assumes that you want R 3.2 & 3.3 on the same system and be able to run either of them when you choose.
- Let’s assume that you already installed R 3.3 by downloading it from CRAN.
- To install R 3.2, you will need to download an old version from CRAN old R
- Before installing R 3.2, run the following commands
sudo pkgutil --forget org.r-project.R.mavericks.fw.pkg
sudo pkgutil --forget org.r-project.R.mavericks.GUI.pkg
sudo pkgutil --forget org.r-project.R.mavericks.GUI64.pkg
- Install R 3.2 by double clicking on *.pkg
- Now, download and install RSwitch (RSwitch link), which it will allow you to switch between R version by clicking on the R version of your like.
Finally I was able to find some documentation on how to configure Sophos VPN UTM.
For years now I have had a successful split tunnel VPN with my Sophos UTM. Recently I’ve wanted to have a full tunnel option for greater security in remote areas (hotel wi-fi, etc.) Unfortunately setting up such a thing in Sophos is NOT straightforward. The biggest problem I had was that no websites would work … Continue reading Configure full VPN tunnel in Sophos UTM →
Just recently with the announcement of Win 10 made available for free, I wanted to upgrade, but got an error message that I can not upgrade due to SVGA drivers compatibility. Between VMware and Microsoft, they are both pointing fingers to one another and nobody wants to take responsibility. So, the easiest way to do it, would be to download the ISO and perform the upgrade yourself.
Here is the direct link -> https://www.microsoft.com/en-us/software-download/windows10ISO.
So, I tested this in Ubuntu 14.04 LTS and Firefox 38. This tool did not worked in Chrome 43.
You will need to add the PPA to your Ubuntu box and then install the program.
- open “Terminal”
- type “sudo add-apt-repository ppa:mjblenner/ppa-hal”. Then go through the prompts
- then, type “sudo apt-get update && sudo apt-get install hal”
- Open up Firefox and give it a ride!
Getting Amazon Prome, 4OD, Demand 5, or Google Play Movies to work on Ubuntu 13.10 requires a little bit of effort, but it can be done.
