R: Scraping the Release Dates of Github Projects

Javalobby Syndicated Feed - Sun, 28-Jun-15 22:00
Continuing on from my blog post about scraping Neo4j’s release dates I thought it’d be even more interesting to chart the release dates of some github projects. In theory the release dates should be accessible through the github API but the few that I looked at weren’t returning any data so I scraped the data together. We’ll be using rvest again and I first wrote the following...

Oracle License Revenue and the MySQL Ecosystem

Javalobby Syndicated Feed - Sun, 28-Jun-15 22:00
Written by Jim Doherty Preview Text:  Oracle was in the news recently with the story of its license revenue declining as much as 17% in the recent quarter. This is blamed on transitioning to the cloud in some publications, but others, such as Bloomberg and TechRepublic, look deeper, seeing open source software responsible for the bulk of it. ...

Scraping Github Pull Requests and Their Code Review Comments

Javalobby Syndicated Feed - Sun, 28-Jun-15 19:30
Github stores its pull-request and code review data in MySql. I’d much prefer a git reperentation for both (JSON, commits, audit trail, etc). Kinda the way Github Wiki pages are stored. That’s an aside though, this article is about storing code-review comments long term. The problem I’m trying to solve is one of deletion of users thich causes their pull requenst commentary to also get...

Drop Books

Javalobby Syndicated Feed - Sat, 27-Jun-15 22:30
The vast majority of books I purchase are for my own enjoyment, but not all of them. There are a few books that I buy over and over, and drop on the desks of friends and colleagues. These books, all technical, are books that I think most programmers will benefit from reading. I call these books "Drop Books"; I drop them and never expect them to be returned. My main motivation for dropping...

Launching Missiles With Haskell

Javalobby Syndicated Feed - Sat, 27-Jun-15 22:30
Haskell advocates are fond of saying that a Haskell function cannot launch missiles without you knowing it. Pure functions have no side effects, so they can only do what they purport to do. In a language that does not enforce functional purity, calling a function could have arbitrary side effects, including launching missiles. But this cannot happen in Haskell. The difference between pure...

Agile is Punk - Agile is Democracy

Javalobby Syndicated Feed - Sat, 27-Jun-15 22:30
From time to time I’ve been heard to say: “Agile is Punk.” But I’ve never explained myself. I’ve also been heard to say things life “Agile is about democratising the workplace” but I’ve never explain myself there either. Let me try… What I mean when I say this is: Agile (software development) has a lot in common with Punk rock. Preview Text:  ...

How Much For This Software?

Javalobby Syndicated Feed - Sat, 27-Jun-15 22:00
"Here is the specification; how much will it cost to create this software?" I hear this almost every day from clients of Teamed.io and prospects that are planning to become our clients and outsource the software development to us. My best answer is "I don't know; it depends." Sounds like a strange response for someone who claims he knows what he is doing, isn't it? "Here is the 20-page...

Docker Events and Docker Metrics Monitoring

Javalobby Syndicated Feed - Fri, 26-Jun-15 23:00
Docker deployments can be very dynamic with containers being started and stopped, moved around the YARN or Mesos-managed clusters, having very short life spans (the so-called pets) or long uptimes (aka cattle).  Getting insight into the current and historical state of such clusters goes beyond collecting container performance metrics and sending alert notifications. ...

The real competitive advantage from Big Data lies in two areas: how you use the data, and how you provide access to the data. The way you address both of those goals can make or break an application – and, in some cases, even...

Business leaders like to be in control of every aspect of their operations, but if any element is outsourced, that sense of governance becomes much more difficult to maintain. Outsourcing can be appealing to organizations looking for talent at reasonable costs - it just takes significant planning to pull off successfully.
