Useful Link: PagerDuty Incident Response Documentation

This documentation from PagerDuty on incident response is pretty good. It would need to be tailored for local conditions but it does highlight aspects of incident response that people might not be aware of (different roles during a major incident, for example). https://response.pagerduty.com/

Repost: ANTLR Trinity

This post is a repost of an article I had on a previous incarnation of this blog. I hadn't intended to transfer it over, as the technology is old now (ANTLR is on version 4), but I recently came acros a slide deck online, where the post was referenced, so I am reposting in case anyone was looking for it. There are 3 components to a really useful software development technology: innovative features, clear and comprehensive documentation, and solid tools. The recent release of ANTLR v3.0 is a perfect example of this. This parser generator tool has all 3 components and each component is done superbly. ANTLR is a parser generator tool that is capable of targeting multiple output languages. Out of the box it will generate Java, Python, C, C#, or Ruby code for parsers. Other target languages are possible if the code generators are written. Amongst its cool features are: LL(*) parsing: This is an extension to the normal, top down with looka

First Post

Hello and welcome to the inane ramblings of an Irish software developer. The title of the blog comes from Lewis Carroll's, Through the Looking Glass . In the book, Alice goes running with the Red Queen, but they don't seem to make any progress. Alice remarks on this, saying, "Well in our country, you'd generally get to somewhere else - if you ran very fast for a long time as we've been doing." The Red Queen replies, "A slow sort of country. Now, here, you see, it takes all the running you can do, to stay in the same place." The Red Queen Effect is quite applicable to the software industry, and as I probably will be talking quite a bit about the software industry, I thought it would be a good name for a blog. I have a few objectives for my new blog. By writing here, I hope to learn how to write well. That is, I hope to learn how to write clearly and concisely, and be interesting at the same time. I also hope that this blog will become a good prof

Useful Links: Logs and Metrics

This article explains why storing log messages alone is insufficient for robust operation of a software service. Metrics also need to be gathered and stored. https://medium.com/@copyconst…/logs-and-metrics-6d34d3026e38 tl;dr - Log volume can spike dramatically when user activity increases, especially when things go wrong. This makes it possible for an alerting system based on logs to be swamped. For a metrics system, volume increases with the number of metrics collected. This is stable and much less likely to fail or slow down during a crisis.
