Aktores

I added a new sample, PingPong, to my actor model implementation in C#

https://github.com/ajlopez/Aktores

The idea is to start measuring message processing performance. I added a variable number of worker threads, that affects the performance. I want to add a TryEnter method call but with a timeout. If some actor is busy, its messages retry process could be intensive in terms of time.

SimpleCards

I started the project

https://github.com/ajlopez/SimpleCards

to implement simple cards and deck to be rendered in web application (browser and mobile). I remember the great HyperCard. This project is simpler: only the cards and their content are specified, no position or render info are needed. There is render code adapted to the application (web browser, mobile) but the decks/cards are agnostic to device.

RustScript

My Rust language interpreter in JavaScript:

https://github.com/ajlopez/RustScript

I added the for command (parse and evaluation), and the built-in range function (to produce an iterator).

SimpleKache

I wrote and published version 0.0.1 of:

https://github.com/ajlopez/SimpleKache

A simple in-memory, in-process cache for Node.js/JavaScript.

SimpleAsync

My project to call a sequence of async/sync functions:

https://github.com/ajlopez/SimpleAsync

now has a map function that support functions with callback, not only sync functions. So, map can received an array and it can transform each elements calling asynchronous functions. I fixed a previous bug related to do, and published the version 0.0.3. Now, I’m starting to refactor the internal implementation. TDD rocks!

Others

I also worked on three non-public projects.

More fun is comming.

Keep tuned!

AjGenesis Agents

I started to add agents support to AjGenesis for Node, Express tasks:

https://github.com/ajlopez/AjGenesisNode-Express

The idea of agents is: instead of having code to render or produce page, code, classes, the agents are queried to solve problems: render this field, render this input, create the validation code, etc. Each agent could accept or not the problem: if an agent specialized in Angular detects that Angular is not being used in the application, then it is not loaded. Work in progress.

Ruby in C#

I updated:

https://github.com/ajlopez/RubySharp

My Ruby interpreter in C#. I added local variables detection. Ruby is a language where the local variables used in an scope can be listed. I wrote code to retrieve the name of local variables from expressions.

Clojure in C#

I worked on:

https://github.com/ajlopez/ClojSharp

There are a few new primitived forms and special form, and more parser/lexer support.

Scala in C#

I started to add dynamic object support to

https://github.com/ajlopez/ScalaSharp

The idea is to have objects with defined methods. Maybe, I will re-implement the object without dynamic methods: these should be defined at compile time, instead of runtime. I’m thinking about the definition of classes for many objects, and singleton classes for only one object.

Rust in JavaScript

I updated my Rust interpreter in JavaScript:

https://github.com/ajlopez/RustScript

with the support of modules, and public functions exposed in modules. I should add the references to them, using double colon operator.

AjLisp in Scala

To practice TDD and the use of SBT (Simple Build Tool), I started:

https://github.com/ajlopez/AjLispScala

Where I’m reimplemented AjLisp ideas in Scala, using scalatest library for TDD

JavaScript Samples

To explore WebGL, canvas, and implement some code katas, I created:

https://github.com/ajlopez/JavaScriptSamples

WebGL is not easy: lot of details to setup an scene. Canvas examples were borrowed from other of my projects. To practice TDD, I started to wrote simple code katas, using SimpleUnit and Node.js

I was working on two non-public projects, too. More fun is coming.

Keep tuned!

Talks

I finished my presentation about Node.js Distributed Applications:

https://github.com/ajlopez/Talks/tree/master/NodeDistributedApps
http://ajlopez.github.io/Talks/NodeDistributedApps/index.html

Last week I gave this talk at the JSConf Uruguay http://jsconf.uy/ Great days, interesting people, projects and ideas. I should post about my experience. In this talk I mentioned my projects:

https://github.com/ajlopez/AjFabriqNode
https://github.com/ajlopez/SimpleStorm
https://github.com/ajlopez/SimpleActors
https://github.com/ajlopez/NodeSamples/tree/master/Fractal/distributed
https://github.com/ajlopez/SimpleGA/tree/master/samples/tspdistr

And I did a quick description of some other basic projects I used to build the demos:

https://github.com/ajlopez/SimpleBus
https://github.com/ajlopez/SimpleQueue
https://github.com/ajlopez/SimpleRemote
https://github.com/ajlopez/SimpleBroadcast
https://github.com/ajlopez/SimpleMessages
https://github.com/ajlopez/ObjectStream

SimpleGammon

I updated my project

https://github.com/ajlopez/SimpleGammon

Now it has to samples: one, with position evaluation at browser, and another with position evalution at server side. Next steps: add worker nodes, at server side, to distributed the position evaluation, maybe with a tree search in many levels (now it explores 2 plies), or more levels using montecarlo.

RustScript

After talking with @LostOracle at JSConfUy, I started an interpreter for Rust Language, in JavaScript:

https://github.com/ajlopez/RustScript

The hello world is working:

https://github.com/ajlopez/RustScript/tree/master/samples/hello

I use and updated my grammar generator

https://github.com/ajlopez/SimpleGrammar

Dog fooding is good!

Annalisa

I added new rules and some refactor to my projects:

https://github.com/ajlopez/Annalisa
https://github.com/ajlopez/PreciosaAnnalisa

I want to add a JavaScript application running at client side, to cover the main use case of Preciosa Project.

I worked on two non-public projects. Now, I’m back at Buenos Aires. More fun is comming!

Keep tuned!
