MultiTail allows you to monitor logfiles and command output in multiple windows in a terminal, colorize, filter and merge.
MultiTail lets you view one or multiple files like the original tail program. The difference is that it creates multiple windows on your console (with ncurses). It can also monitor wildcards: if another file matching the wildcard has a more recent modification date, it will automatically switch to that file. That way you can, for example, monitor a complete directory of files. Merging of 2 or even more logfiles is possible. It can also use colors while displaying the logfiles (through regular ex...

Stream processing, Event sourcing, Reactive, CEP… and making sense of it all - Confluent
"Some people call it stream processing. Others call it Event Sourcing or CQRS. Some even call it Complex Event Processing. Sometimes, such self-important buzzwords are just smoke and mirrors, invented by companies who want to sell you stuff. But sometimes, they contain a kernel of wisdom which can really help us design better systems.

In this talk, we will go in search of the wisdom behind the buzzwords. We will discuss how event streams can help make your application more scalable, more reliable and more maintainable. [...]

In this presentation, I’m going to discuss some of the ideas that people have about processing event streams. The idea of structuring data as a stream of events is nothing new, but I’ve recently noticed this idea reappearing in many different places, often with different terminology and different use cases, but with the same underlying principles."

roidrage/lograge: An attempt to tame Rails' default policy to log everything.
"Lograge is an attempt to bring sanity to Rails' noisy and unusable, unparsable and, in the context of running multiple processes and servers, unreadable default logging output. Rails' default approach to log everything is great during development, it's terrible when running it in production. It pretty much renders Rails logs useless to me.

Lograge is a work in progress. I appreciate constructive feedback and criticism. My main goal is to improve Rails' logging and to show people that they don't need to stick with its defaults anymore if they don't want to.

Instead of trying solving the problem of having multiple lines per request by switching Rails' logger for something that outputs syslog lines or adds a request token, Lograge replaces Rails' request logging entirely, reducing the output per request to a single line with all the important information, removing all that clutter Rails likes to include and that gets mingled up so nicely when multiple processes dump their output into a single file.

Instead of having an unparsable amount of logging output like this:

Started GET "/" for 127.0.0.1 at 2012-03-10 14:28:14 +0100
Processing by HomeController#index as HTML
Rendered text template within layouts/application (0.0ms)
Rendered layouts/_assets.html.erb (2.0ms)
Rendered layouts/_top.html.erb (2.6ms)
Rendered layouts/_about.html.erb (0.3ms)
Rendered layouts/_google_analytics.html.erb (0.4ms)
Completed 200 OK in 79ms (Views: 78.8ms | ActiveRecord: 0.0ms)

you get a single line with all the important information, like this:

method=GET path=/jobs/833552.json format=json controller=jobs action=show status=200 duration=58.33 view=40.43 db=15.26

The second line is easy to grasp with a single glance and still includes all the relevant information as simple key-value pairs. The syntax is heavily inspired by the log output of the Heroku router. It doesn't include any timestamp by default, instead it assumes you use a proper log formatter instead."

Minimalicious testing in Ruby 1.9 with MiniTest - Random notes by Arvid Andersson
"In this blog post I am going to try to do a introduction on writing tests in the style of Behavior Driven Development (BDD) specifications, also called specs, with ruby's MiniTest framework. BDD is a big subject and I am going to focus on the tools MiniTest provides for specifying the behaviour of code. There are a lot more to BDD than what is mentioned in this blog post."
