Troy

2016-09-07T00:00:00+00:00

Troy is an open source macro-based Cassandra driver, similar to Slick and Quill, provides type-safe & compile-time checking for database queries. Nevertheless, it doesn’t impose a DSL to express the queries in Scala. Instead, it allows developers to write plain Cassandra-query-language (CQL) queries within Scala code, complete with schema validation. In addition, it provides cross-validation against the previous versions, ensuring safe and smooth schema migrations.

It is worth noting that Troy doesn’t connect to Cassandra during compilation. Instead, the schema is provided as CQL scripts, checked-in within same code base, consisting of plain CREATE TABLE CQL statements. That get’s loaded at compile-time into a light-weight Schema engine capable of analysing queries and providing information about column types. Those CQL scripts can be written as increments, by adding new scripts containing ALTER TABLE statement, instead of editing existing scripts. This allows Troy to check backwards and forward compatibility of queries against different versions of the schema. As well as providing tools to write migration scripts.

Currently, Troy uses reflection-based black-box macros. But also has a working proof-of-concept using the new style inline/meta as well.

All you need to know about Play’s routing DSL

2016-03-14T00:00:00+00:00

Play 2.4 introduced a new way to write your applications that can be appealing to developers with minimalistic preferences. Now it’s straightforward to embed Play into your application, adding only the necessary dependence, and using a sexy routing DSL.

In this post, we will go through creating an embedded Play application step by step, then we will take a tour of Play’s new routing DSL features, explaining different usecases, including some advanced ones.

Inspecting Akka’s Supervision Strategy

2016-02-23T00:00:00+00:00

Akka’s OneForOneStrategy has a maxNrOfRetries parameter, that would result in a Stop rather than a Restart if its limit was exceeded. How can we Escalate instead?

I won’t say this course is enough. But it is more than a good boost for your skills to continue learning through Coursera, edx and other online eductions websites.

Structure & Interpretation of Computer Programs

2015-01-02T00:00:00+00:00

This course is about the art of programming, how to think and write beautiful, readable code. This course is not about Javascript details, we are only using Javascript to demonstrate programming concepts that can be applied using other languages too.

#Target Audience

Either you are completely new to programming or you have some experience but want to improve.
You want to be a code artist! not just a developer!
Committed, Committed, Committed! This is not an easy course. You have to be completely free, dedicated and focused.

##Contents The course is based on the first 3 chapters of SICP and it’s Javascript version, in addition to some extra content. The following is highlights of some topics to be discussed in the course.

Introduction
- Where can I use Javascript
- What is an interpreter
- Exploring tools
Basics of programming (Expressions, Combinations, Abstractions, Conditionals and Predicates)
Functions
- Functions as a way of abstraction
- What is recursion (Linear, Tree, and Logarithmic)
- recursion vs loop
How to analyse performance and memory consumption of programs
Higher order functions, and Closures
Immutable Data (Building your own datastructres)

- Sets
- Binary Trees
Mutable Data (Building your own datastructres)
- Lists
- Queues
- Tables

##Duration We are going to simulate a real work environment. The course consists of 6 classes, each class is 9 hours long, including breaks.

##Location The course will be held in Mansoura, Egypt.

##Homework Exercises in the book are important part of the experience. Your solutions should be published on your Github account, so that you can show off your work. Best solution will be merged into the main repo. If you don’t know about Github or Git. Don’t worry, I’ll introduce them.
