Grimoire Lab-GitHub - Stats On Steroids

Grimoire Lab is an open source toolkit built on Python, Elasticsearch and Kibana. It taps into GitHub's raw data through Perceval, a module designed for retrieving data from repositories related to software development.

Perceval forwards the data to another tool for filtering, the so called Sorting Hat, responsible for managing and merging identities that correspond to the same real person/commiter and potentially come from different sources, before finally rendering the data manageable and accessible through rich UI Kibiter dashboards. Kibiter, a fork of Kibana, is what enables the user to create and edit visualizations as well as perform queries facilitated by the underlying Elasticsearch REST APIs.

JSON Feed - The New RSS?

SON Feed is a new take on the web syndication format, but unlike RSS and Atom it's in JSON, not XML. So what does it try to do better?

Mainly overcome the perils of XML; it's complex, heavyweight, difficult to parse and not in sync with the current trend wanting web data exchange happening almost exclusively in JSON document representation.

In contrast, JSON is easier to both write and parse, manipulate and consume, especially given that its data types are exact reflections of their native Javascript counterparts.
Devised by Brent Simmons, the original developer of the popular NetNewsWire and Manton Reece creator of Micro Blogs, both with a great background on publishing with RSS, it's a certainty that JSON Feed will emerge as a strong competitor to both Atom and RSS, being based upon their decade long experience on decentralized formats.

On top of that it also tries to tackle a few other issues plaguing RSS, mainly the lack of realtime client notification whe…

Graphcool Eases Your Way Into GraphQL

GraphQL, dubbed by many as REST's successor, is a query language in which you can query database driven, JSON schema-exposed APIs. The problem is that because it is so different from REST, getting the hang of GraphQL when starting out is not that easy.
But why go the trouble now that there are cloud-based FaaS (Framework as a Service) services such as Graphcool which take the pain out of the process of setting up, configuring, running and testing your GraphQL backend?
Graphcool is a newly established GraphQL backend for mobile and web developers that lives on the AWS cloud:
Data is persisted in a high-availability cluster of AWS Aurora databases combined with a Redis-powered caching layer.
Files are securely stored in Amazon S3 and can be accessed through a fast CDN.
Business Logic is implemented as serverless functions and deployed to AWS Lambda.
Website Hosting uses Netlify's CDN. and lowers the entry barrier in getting into GraphQL.

With Graphcool you don't have…

Perlito - 4 Years On

Perlito, the open source compiler collection that implements a Perl5 and a Perl6 compiler has just launched a brand new Java backend. It seemed a good time to catch up with the project by talking to its lead contributor, Flavio Glock.

Last time I interviewed Flavio Glock about Perlito was back in 2013 when the project was in its first steps. At that time Perlito could compile Perl 5 or Perl 6 programs into various backends,  including JavaScript, Python, Ruby and Go, but it was also designed with extensibility from the ground up so it could be further extended to other backends in the future.

Well this time has come, with Flavio just announcing a brand new Java backend! In those 4 years the project has really taken off, a lot has changed, and given the opportunity of this new and great development I thought that a follow up was in order.

Flavio was once more deeply insightful and provided links to three very interesting video presentations on the topic that took place du…

AWS and Ionic Team Up In Starter Project

Amazon is quick in recognizing that just offering support for a number of popular programing languages is not enough to lure hoards of developers to the platform. That's why we are seeing a move towards wrapping its AWS services with greater user-friendliness.

The start was made with the introduction of CodeStar, which aimed to simplify the setting up of a project's AWS infrastructure, especially  with regard to policy and authorization, as we examined in CodeStar to Simplify Development On AWS. 

It continues this trend with the release of the open source Ionic AWS starter project Mobile Web and Hybrid Application which aims to act as a skeleton, or boilerplate, Ionic application tweaked in such a way to give developers a headstart in configuring their mobile Ionic front-end applications in relation to an AWS backend.

Three Tips for the Linux Shell Addict

This time around we have three great tips for the Linux shell addict, three sites that will increase your productivity and save valuable time in your daily interactions with the shell.

The first one is ok-b.org. It's a shell snippet search engine where you get to  describe the task you are after in natural English and in return be presented with closely related snippets.

For example, in looking up "How to list only files?", will bring up:
Bash: How to list only files?
find . -maxdepth 1 -type fls -l | egrep -v '^d'ls -l | grep -v '^d'
List only common parent directories for files
read -r FIRSTLINE
DIR=$(dirname "$FIRSTLINE") while read -r NEXTLINE; do
  until [[ "${NEXTLINE:0:${#DIR}}" = "$DIR" || "$DIR" = "/" ]]; do
    DIR=$(dirname "$DIR")
  done
done echo $DIR
How to list files in directory using bash?
for file in /source/directory/*
do
    if [[ -f $file ]]; then
        #copy stuff ....
    fi
