Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Acos - Advanced Content Server

Acos server and related sub-projects are a method of distributing browser-based smart learning content in a reusable and interoperable way. The core idea is that different types of smart learning content can be hosted in Acos and offered to various Learning Management Systems (LMS) using different protocols.

This is a joint project with PAWS Lab at the University of Pittsburgh and Learning + Technology research group at Aalto University aiming at producing smart learning content on Python programming. The project Advanced Distributed Learning (ADL) Initiative.

The project is led by Professor Peter Brusilovsky. In Aalto University, the following persons are working with the project:

  • Professor Lauri Malmi
  • Lassi Haaranen
  • Teemu Sirkiä

The Acos server is designed and implemented by Lassi Haaranen and Teemu Sirkiä.

Installation

To install Acos server, clone the repository and install necessary dependencies by running npm install in the acos-server directory. Note that acos-server expects npm version 3 in order to install dependencies of content packages correctly.

For the time being, to install content types and packages use github notation with npm. E.g.:

# For JSVEE content type
npm install github:acos-server/acos-jsvee
# For JSVEE Python content
npm install github:acos-server/acos-jsvee-python

# When using npm3 you can also install the dependencies of a content package
# straightaway, e.g. this would also install acos-jsparsons correctly:
npm install acos-jsparsons-python

Running

To run the server use node bin/www.

Key Concepts

Acos Concept

For content developers, Acos offers an easy way to add new content without the need to delve into details of various protocols used to transmit learning content.

For educators, Acos offers a repository of ready-made content that can easily be incorporated into an existing course. With certain content types, customization is also possible.

Content Type

Content type is an Acos package that defines a type of smart learning content. It does not contain any actual learning activities or exercises but rather the libraries and other code needed for those activities. Activities are defined in Content Packages.

Content Package

Content packages defined concrete learning activities of a particular content type. It always depends on the parent content type package to function. Different sets of activities of a particular type are packaged into content packages, e.g. packages for program visualizations (acos-jsvee-) exists for various programming languages.

Protocol

Different learning management systems use various protocols to transfer smart learning content and associated metadata such as points a learner has achieved. An example of such a protocol is Learning Tools Interoperability.

Content within Acos can be utilized by various supported protocols. These link external protocols, used with LMSs, to Acos content packages and types. Content types are implemented in a protocol-agnostic manner, so after a content type is implemented as an Acos-package it can be utilized by all supported protocols.

Tools

Acos also has the concept of a tool where various utility packages can be installed. As an example, Python code can be submitted to acos-python-parser in order to receive concepts used in the code which are parsed from AST.

Development

Please see doc/development.md.
