Being as a general purpose programming language, it is influenced by many ancestors including, Erlang, Haskell, Java, Lisp, OCaml, Scheme, and Smalltalk. Scala has many attractive features, such as cross-platform taking advantage of JVM; as well as with higher level abstraction agnostic to the developer providing immutability with persistent data structures, pattern matching, type inference, higher or- der functions, lazy evaluation and many other functional programming features. -

The Scala Experience Safe Programming Can Be Fun!
The Scala Programming Language Mooly Sagiv Slides taken from Martin Odersky (EPFL) Donna Malayeri (CMU) Hila Peleg (Technion) Modern Functional Programming • Higher order • Modules • Pattern matching • Statically typed with type inference • Two viable alternatives • Haskel • Pure lazy evaluation and higher order programming leads to Concise programming • Support for domain specific languages • I/O Monads • Type classes • ML/Ocaml/F# • Eager call by value evaluation • Encapsulated side-effects via references • [Object orientation] Then Why aren’t FP adapted? • Education • Lack of OO support • Subtyping increases the complexity of type inference • Programmers seeks control on the exact implementation • Imperative programming is natural in certain situations Why Scala? (Coming from OCaml) • Runs on the JVM/.NET • Can use any Java code in Scala • Combines functional and imperative programming in a smooth way • Effective libraries • Inheritance • General modularity mechanisms The Java Programming Language • Designed by Sun 1991-95 • Statically typed and type safe • Clean and Powerful libraries • Clean references and arrays • Object Oriented with single inheritance • Interfaces with multiple inheritance • Portable with JVM • Effective JIT compilers • Support for concurrency • Useful for Internet Java Critique • Downcasting reduces the effectiveness of static type checking • Many of the interesting errors caught at runtime • Still better than C, C++ • Huge code blowouts • Hard to define domain specific knowledge • A lot of boilerplate code • -
1 Ocaml for the Masses
PROGRAMMING LANGUAGES OCaml for the Masses Why the next language you learn should be functional Yaron Minsky, Jane Street Sometimes, the elegant implementation is a function. Not a method. Not a class. Not a framework. Just a function. - John Carmack Functional programming is an old idea with a distinguished history. Lisp, a functional language inspired by Alonzo Church’s lambda calculus, was one of the first programming languages developed at the dawn of the computing age. Statically typed functional languages such as OCaml and Haskell are newer, but their roots go deep—ML, from which they descend, dates back to work by Robin Milner in the early ’70s relating to the pioneering LCF (Logic for Computable Functions) theorem prover. Functional programming has also been enormously influential. Many fundamental advances in programming language design, from garbage collection to generics to type inference, came out of the functional world and were commonplace there decades before they made it to other languages. Yet functional languages never really made it to the mainstream. They came closest, perhaps, in the days of Symbolics and the Lisp machines, but those days seem quite remote now. Despite a resurgence of functional programming in the past few years, it remains a technology more talked about than used. It is tempting to conclude from this record that functional languages don’t have what it takes. They may make sense for certain limited applications, and contain useful concepts to be imported into other languages; but imperative and object-oriented languages are simply better suited to the vast majority of software engineering tasks. -

Installing and Running Tensorflow
Installing and Running Tensorflow DOWNLOAD AND INSTALLATION INSTRUCTIONS TensorFlow is now distributed under an Apache v2 open source license on GitHub. STEP 1. INSTALL NVIDIA CUDA To use TensorFlow with NVIDIA GPUs, the first step is to install the CUDA Toolkit. STEP 2. INSTALL NVIDIA CUDNN Once the CUDA Toolkit is installed, download cuDNN v5.1 Library for Linux (note that you will need to register for the Accelerated Computing Developer Program). Once downloaded, uncompress the files and copy them into the CUDA Toolkit directory (assumed here to be in /usr/local/cuda/): $ sudo tar -xvf cudnn-8.0-linux-x64-v5.1-rc.tgz -C /usr/local STEP 3. INSTALL AND UPGRADE PIP TensorFlow itself can be installed using the pip package manager. First, make sure that your system has pip installed and updated: $ sudo apt-get install python-pip python-dev $ pip install --upgrade pip STEP 4. INSTALL BAZEL To build TensorFlow from source, the Bazel build system must first be installed as follows. Full details are available here. $ sudo apt-get install software-properties-common swig $ sudo add-apt-repository ppa:webupd8team/java $ sudo apt-get update $ sudo apt-get install oracle-java8-installer $ echo "deb http://storage.googleapis.com/bazel-apt stable jdk1.8" | sudo tee /etc/apt/sources.list.d/bazel.list $ curl https://storage.googleapis.com/bazel-apt/doc/apt-key.pub.gpg | sudo apt-key add - $ sudo apt-get update $ sudo apt-get install bazel STEP 5. INSTALL TENSORFLOW To obtain the best performance with TensorFlow we recommend building it from source. First, clone the TensorFlow source code repository: $ git clone https://github.com/tensorflow/tensorflow $ cd tensorflow $ git reset --hard 70de76e Then run the configure script as follows: $ ./configure Please specify the location of python.
