How to Ensure Self Describing Log Data Using Log4Net

In a previous article, The Benefit of Having an Enterprise Logging Policy [/2016/04/06/the-benefit-of-having-an-enterprise-logging-policy/], I presented the case for always using self-describing data formats when logging information. Using self-describing formats, such as key-value pairs and JSON, saves time and effort in terms of indexing and subsequently querying your logs on the backend. Also, logs that use a self-describing data format are easier to understand by anyone, at any time. In t

How to: Send SMS messages to Logentries in under 5 minutes (maybe 10)

The “Internet Of Things” continues to be talked about a lot with an increasing number of devices now containing some sort of smart functionality which can be interacted with. Here’s a great article about end-to-end IoT monitoring [/2014/12/end-to-end-iot-monitoring-with-log-data/] by colleague David Tracey. However, not all IoT devices can be in locations with WiFi or 3/4G coverage, so they can not easily (or at all) send or receive data over the internet, and instead rely on standard cellula

How to Compare Google Compute Engine & AWS EC2

Which Virtual Machine is Best: Google’s Compute Engine or Amazon’s EC2? It Depends. The Internet might seem like a Wild West of chaotic connections because it often is.

Do You Still Email Yourself from Your Code? How to Stop the Madness

A few years back now, I took on an assignment to help a company modernize a series of legacy .NET applications.  One of these did some back office processing.  A vendor would stick some files on a shared drive, and a windows scheduled task would invoke this bit of code to parse the file, apply a whole slew of business rules to its contents, and then update the appropriate internal systems.  The details are both proprietary and uninteresting, so I will spare you those.

Brics Vs RE2/J

By Benoit Gaudin and Mark Lacomber Regular Expressions When it comes to searching unstructured data, regular expressions are a very useful and powerful tool. The power provided by popular regular expression libraries does come with a significant performance cost in some cases though, both when compiling regular expressions into automata (state explosion problem when determinising automata) and when using these automata to match input. These constraints are usually acceptable for individuals ne

A point of @Contention- cache coherence on the JVM

Java 8’s major changes- lexical closures, the stream API, e.t.c have overshadowed a slew of little gems, one of which I only discovered the other day- the @Contended annotation. False Sharing Chances are you’re reading this on a device with more than one CPU. There’s therefore also quite a good chance the you have more than one thread of execution running at the exact same time. There’s an equally good chance that some of your fancy multiprocessor CPU’s on-die memory (aka L2/3 cache) is share

Deciphering MySQL Logs: The What, Why, and How

Logs are one of the best ways to understand what a server is doing. Thankfully, MySQL has no shortage of log activity to assist a DBA in its maintenance. It writes out its activity to 5 different logs.  This post will take a look at the existing MySQL logs and how they assist the administrator. * On Windows, - The log is written to the data directory with a .err extension even if not explicitly enabled. * Errors are automatically written to the Event Log. This behavior is standard and

TypeScript Language Primer

What is TypeScript? TypeScript is an open source typed superset of JavaScript [] which compiles to plain JavaScript. Many people have considered JavaScript’s loose typing as a problem, but now TypeScript offers a solution to that. Specifically, TypeScript allows you to code with decorators/annotations, classes, interfaces, private properties and typing compliance. We also might say that TypeScript is ES6 with some extra options. What does TypeScript do?
