A Simple Jekyll Portfolio Theme

Posted on June 3, 2019October 14, 2020 by Robert Hafner

I write a lot of software, and I like sharing it with the world. So when I decided to redo my portfolio it was only natural that I release the theme itself as an open source project.

GitStars – A Github API for Front End Development

Posted on May 27, 2019May 26, 2019 by Robert Hafner

TLDR: GitStars Github, Documentation, and New Badges. Developers love badges. For these reason there are a ton of different Github Badges websites that let you build out your own badges for your projects. Most of them have the same issue though- they stop working quickly due to the Github API Ratelimiting, which only allows 60…

secretcli – an interface for the AWS Secrets Manager

Posted on October 21, 2018October 20, 2018 by Robert Hafner

I love the AWS Secrets Manager, but have found the awscli tools for it to be a bit bulky. Most of the time all I want to do is download a file, edit it, and upload it again- and even then I normally just want to quickly change a single value inside of my “secret”….

urlparser – a simple python program for extracting info from URLs

Posted on October 13, 2018October 12, 2018 by Robert Hafner

I regularly run into the need to use part of a URL inside of shell scripts- such as extracting the hostname and port from a URL in order to check if the service is reachable- and got a bit tired of screwing with regex. The urllib python library’s parse component is a great tool for…

ec2details, the missing EC2 Instance Metadata API

Posted on March 28, 2018April 3, 2018 by Robert Hafner

When working with the AWS EC2 service in a programmatic way I’ve repeatedly run into a simple problem- how can I get up to date metadata about the various instance types in a programmatic way? It turns out this simple problem does not actually have a simple solution. AWS offers their Bulk API, which has…

GitConsensus now available as a Github App

Posted on February 28, 2018February 27, 2018 by Robert Hafner

Last year I introduced a way to manage open source projects with GitConsensus, an open source Github bot that anyone can download and run. Today running GitConsensus is even easier with the availability of a new GitConsensus GitHub App. Developers can now add GitConsensus directly to their repositories simply by enabling it in GitHub and…

Manage Github Pull Requests with gitconsensus

Posted on August 23, 2017August 23, 2017 by Robert Hafner

This weekend I dug into the Github API to build gitconsensus, which lets communities create truly democratic projects using Reactions as a voting mechanism. Projects can define consensus rules (minimum age of pull request, quorum for votes, threshold needed for passing) using a yaml file in their project root. Pull Requests that meet the consensus…

Introducing jsonsmash – work with large json files easily

Posted on May 29, 2017May 28, 2017 by Robert Hafner

Over the last year I’ve run into some pretty massive JSON files. One recent examples is from AWS, which publishes a 120mb file containing a list of their available services that they have yet to provide documentation for. Attempting to open that in a standard editor is not going to be pleasant, and while tearing…

Stash v0.14 Released with PSR-6 Support

Posted on February 10, 2016 by Robert Hafner

Release v0.14.1 is a major update to Stash, and quite likely the last line of releases before v1.0.0. The biggest addition is support for PSR-6. Stash now implements the various interfaces natively, allowing it to be directly injected into PSR-6 compliant libraries. This did require a few API changes (which prompted some cleanup of deprecated…

New Release of Stash and Stash Bundle

Posted on August 3, 2015August 2, 2015 by Robert Hafner

Stash 0.13.1 Dropped support for PHP 5.3. Updated dependencies. Removed various PHP warnings (exceptions are still thrown where needed). Various optimizations, such as reduced function calls during repeated operations. Added “isPersistent” method to driver classes. Stash Bundle v0.5.1 Dropped support for PHP 5.3. Added ‘logger’ config parameter to caches so that they may be injected…
