Embarcadero has released its latest version of RAD Studio, 10.2 Tokyo.
There is the first Linux LLVM-based compiler for Linux Enterprise development, with support for RedHat Enterprise Linux and Ubuntu Server.
To get started with Ubuntu, run the following commands in a terminal:
sudo apt-get updatesudo apt-get upgrade
sudo apt-get install joe wget p7zip-full curlsudo apt-get install openssh-serversudo apt-get install build-essentialsudo apt-get install zlib1g-devsudo apt-get install libcurl4-gnutls-dev
On distributions of Linux supporting yum, use the following:
yum install glibc-staticyum install glibc-develyum install zlib-develyum install compat-libstdc++-33yum install compat-gcc-44-c++
Then, extract PAServer using the tar.gz, and run it.
In 2017, with the release of Delphi 10.2 Tokyo, Embarcadero introduced a specialized implementation of the Observer pattern into the System.Classes unit. While it has been in the wild for 9 years, it remains a "hidden" architecture for many, primarily because it serves as the invisible engine behind LiveBindings. Other than live bindings, you can also use the Observer pattern as a way to update component settings to the Windows registry, an .ini file, or persist it elsewhere.
