JavaScript Trends

Maris has presented JavaScript trends. This lecture started with the history of JavaScript, its usage in the very beginning and the way it has developed. The main goal of the presentation was to show that starting from the language for the annoying popups and alerts a JavaScript turned to the language that is very powerful. New technologies and frameworks are introduced which make JavaScript really powerful. Ajax requests, hardware acceleration, native mobile applications even server code is something that can be used with JavaScript nowadays. And the most amazing thing is that presentation was prepared with JavaScript framework help. Slides: http://www.rvl.io/zemgalis/javascript-trends

TDD – Why and How?

Raimonds in his presentation introduced the public with the Test Driven Development (TDD) which is a software development process that relies on the repetition of a very short development cycle: first the developer writes an initially failing automated test case that defines a desired improvement or new function, then produces the minimum amount of code to pass that test and finally refactors the new code to acceptable standards. Raimonds clearly described the benefits of using this approach and the problems which typically arise if software development and testing are done by separate individuals or teams. Presentation included practical demo of writing software on the spot implementing TDD approach. Source code for the demo with step by step guide are available from his GitHub public repository.

This time there will be a lot of information about JavaScript and TDD.

Venue and time for this event: 15.11.2012 18:30 at Hotel "Radi un draugi", Mārstaļu iela 3.

Here's the speaker lineup:

• Māris Zemgalis from C.T.Co will talk about "JavaScript Trends"
  (Language – English )
  JavaScript was used for displaying alert boxes and opening annoying pop-up windows.. That was the common use for it for some long time.. It was then.. Now in the era of browser wars JavaScript is used to build enterprise level apps in browser environment, to build native & hybrid mobile apps and even used for building server side applications. In presentation I'll cover the demise of Flash, rise of the JavaScript frameworks and fancy tools to make your work productive and entertainment more fun.
  Tags: JavaScript, node.js, Titanium, PhoneGap, Backbone.js

  Māris Zemgalis helps people to get things done by giving them simple and beautiful tools to organize themselves. He has enthusiasm for beautiful, pragmatic code and an eye for simplicity.

• Surprise
• Raimonds Simanovskis from eazyBI will talk about "Test Driven Development (TDD) – Why and How?"
  (Language – English or Latvian)
  There are many myths about Test Driven Development (TDD) – takes too much time, not applicable, not working in real life etc. In this presentation these myths will be "busted" and main benefits of TDD will be explained and recommendations how to try it out and start doing. In the end small practical live TDD will be demonstrated using JavaScript.

Requirement: Code Quality – Gunta Strode

The main idea behind this presentation was that developer should write the code in such way if person who will have to maintain this code afterwards is a maniac who will come after him or her with a knife. Gunta Strode also wanted to show that good code is very subjective and depends on who is looking at the code. She told that good code has meaningful names and code is simple and self-documenting and company or Microsoft guidelines are taken into account. Everyone in a project should care about code quality!

Functional programming – F# – Valdis Iļjučonoks

Valdis has a goal to learn a new programming language every year and this time he got to F#. Valdis believes that F# didn’t become mainstream and is great tool for solving various problems with unconventional methods. Through the course of the presentation Valdis showed simple examples and many versions of the same solution. Unusual aspects of the F# syntax and tools for comfortable work with the language were also reviewed. A very appropriate question for the topic was: “Why learn this language and where can it be applied?”.  The main fields are financial, insurance, mathematical models, life insurance which has very complicated formulas and research. Of course the language also enriches your general view of problem solving.

PHP – life after fork() – Arvīds Godjuks

Arvīds spoke about his personal experience working with PHP daemons, about stereotypes, cases of utilization, as well as methods of avoiding various non-obvious mistakes. In general the presentation was quite constructive as well as multilateral, quite fully covering the topic. Solutions and tools for using PHP daemons for personal objectives as well as production were reviewed. From personal experience Arvīds knows that he found a rather convenient and useful tool.
