Installing .NET on Debian 9

After installing Visual Studio Code I followed the instructions from .NET Tutorial – Hello World in 10 minutes, basically:

wget -qO- https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.asc.gpg
sudo mv microsoft.asc.gpg /etc/apt/trusted.gpg.d/
wget -q https://packages.microsoft.com/config/debian/9/prod.list
sudo mv prod.list /etc/apt/sources.list.d/microsoft-prod.list
sudo chown root:root /etc/apt/trusted.gpg.d/microsoft.asc.gpg
sudo chown root:root /etc/apt/sources.list.d/microsoft-prod.list

Then:

sudo apt-get update
sudo apt-get install dotnet-sdk-2.1

Then for example to create a new console project:

dotnet new console -o myApp
cd myApp

I ended up reading MICROSOFT SOFTWARE LICENSE TERMS for the MICROSOFT .NET LIBRARY which included this doozy:

The software may collect information about you and your use of the software, and send that to Microsoft.

Ah, Microsoft. You haven’t changed.

I found some notes about how to disable telemetry:

Telemetry
———
The .NET Core tools collect usage data in order to help us improve your experience. The data is anonymous and doesn’t include command-line arguments. The data is collected by Microsoft and shared with the community. You can opt-out of telemetry by setting the DOTNET_CLI_TELEMETRY_OPTOUT environment variable to ‘1’ or ‘true’ using your favorite shell.

Read more about .NET Core CLI Tools telemetry: https://aka.ms/dotnet-cli-telemetry

I have added the opt-out environment variable via jj5-bin.

Installing latest version of Scala on Debian

So this is basically a combination of this and this:

sudo apt-get purge scala
sudo apt-get autoremove

cd ~/desktop/scala
wget http://downloads.lightbend.com/scala/2.11.8/scala-2.11.8.tgz
tar xzf scala-2.11.8.tgz
sudo mv scala-2.11.8 /usr/share/scala

sudo ln -s /usr/share/scala/bin/scala /usr/bin/scala
sudo ln -s /usr/share/scala/bin/scalac /usr/bin/scalac
sudo ln -s /usr/share/scala/bin/fsc /usr/bin/fsc
sudo ln -s /usr/share/scala/bin/sbaz /usr/bin/sbaz
sudo ln -s /usr/share/scala/bin/sbaz-setup /usr/bin/sbaz-setup
sudo ln -s /usr/share/scala/bin/scaladoc /usr/bin/scaladoc
sudo ln -s /usr/share/scala/bin/scalap /usr/bin/scalap

Everything is easy when you know how!

Installing Subversion on Mac OS X with WebDAV support (serf library)

cd ~/Development/svn-install
wget http://prdownloads.sourceforge.net/scons/scons-2.3.4.tar.gz
wget http://mirror.ventraip.net.au/apache/apr/apr-1.5.1.tar.gz
wget http://mirror.ventraip.net.au/apache/apr/apr-util-1.5.4.tar.gz
wget http://mirror.ventraip.net.au/apache/subversion/subversion-1.8.10.tar.gz
tar xzf scons-2.3.4.tar.gz
tar xzf apr-1.5.1.tar.gz 
tar xzf apr-util-1.5.4.tar.gz
tar xzf subversion-1.8.10.tar.gz
cd scons-2.3.4
sudo python setup.py install
cd ../apr-1.5.1
./configure --prefix=/usr/local
make
sudo make install
cd ../apr-util-1.5.4
./configure --with-apr=/usr/local --prefix=/usr/local
make
sudo make install
cd ../subversion-1.8.10
sh get-deps.sh serf
cd serf
scons APR=/usr/local APU=/usr/local OPENSSL=/usr/local PREFIX=/usr/local
sudo scons PREFIX=/usr/local install
cd ..
./configure --with-openssl --with-serf=/usr/local --prefix=/usr/local
make
sudo make install

Nuff said!

Oh, wait… there’s a problem with misconfigured CA certificates…

cd ~/Development/svn-install
wget https://distfiles.macports.org/MacPorts/MacPorts-2.3.3-10.10-Yosemite.pkg

Run the MackPorts*.pkg…

xcode-select --install

Then…

sudo /opt/local/bin/port install curl-ca-bundle

Then…

sudo -s
cd /System/Library/OpenSSL/certs/
ln -s /opt/local/etc/openssl/cert.pem cert.pem
cd /usr/local/etc/openssl/certs
ln -s /opt/local/etc/openssl/cert.pem cert.pem

Testing:

openssl s_client -connect www.progclub.org:443 -CApath /opt/local/etc/openssl/

Using MacPorts OpenSSL:

sudo port install openssl
cd ~/Development/svn-install/subversion-1.8.10/serf/
scons APR=/usr/local APU=/usr/local OPENSSL=/opt/local PREFIX=/usr/local
sudo scons PREFIX=/usr/local install

Done!
