Search Your Gmail Messages with ElasticSearch and...
If you’d like to check out ElasticSearch, there’s already lots of options where to get the data to feed it with. You can use a Twitter or Wikipedia river to fill it with gigabytes of public data, or you can feed it very quickly with some RSS feeds.
But, let’s get a bit personal, shall we? Let’s feed it with your own e-mail, imported from your own Gmail account.

Monittr: A Ruby and Web Interface for Multiple...
On my current contract, we have Monit set up to monitor a number of servers. Obviously, when you monitor something, you’d like to check its status from time to time. And while the default Monit web interface is good enough for a quick check of one system, it has several major shortcomings.
You have to remember or bookmark the URL and credentials for the interface. The interface is “good...

Explaining Ruby on Rails Infrastructure...
Last week, I had a workshop on Rails infrastructure, deployment and hosting for one of the major hosting companies in Czech Republic, Active24.
I was confronted with the task of explaining and showing the various pieces (web server, application server, configurations, RubyGems management, etc) without browsing some previously setup server, opening configuration files in Vim, and relying on blind...

Doplněk k přednášce o CouchDB na Webexpo 2010
Děkuji všem za online i offline reakce na moji přednášku o CouchDB. Snažil jsem se věnovat hodně prostoru obecnějším otázkám spojeným s využitím „netradičních“ databází, které CouchDB dobře reprezentuje a zároveň ryze praktickým zkušenostem, které jsem díky intezivnímu používání CouchDB za poslední rok získal. V tomto článku bych rád dodatečně doplnil či upřesnil některá témata či zodpověděl...

Resque Ruby lessons: Do not abuse rescue →
I was just about to fix this with something akin to rescue NoMethodError; [], but this solution from @defunkt makes so much more sense, is &infinity; × more secure, and just right. You should read Resque’s source instead of those blog post you may be wasting your time with.

Rack Middleware Use Case Examples
At the Prague Ruby meetup on Wednesday, I had a talk about Rack and middleware. In trying to deliver as fast as possible, I kinda forgot the main point of the talk: explaining why it matters. So let’s try to remedy it a bit in this way, at the very least.
Rack
Let’s briefly state the obvious so we get a starting point. So, what is Rack? Rack is this:

Create Printable PDF Cards from Your Pivotal...
If there’s a better project management tool for Agile workflow then Pivotal Tracker I have yet to find it. If you haven’t already, do check it out for user story management and reporting.
That’s why I was shocked to discover that it does not provide any sort of printable output. You just cannot print the cards. I have never noticed, not having the need on smaller projects.

Fix Textmate's Shoulda bundle broken shortcutes...
When you’re using Shoulda — and you should :) — on a Mac, you’re probably addicted to ⌘⇧R and ⌥⇧R shortcuts for running currently focused should/context.
That works rather well until your testfile is deeply nested (like in test/unit/my_module/something/complicated_test.rb) — then it falls on it’s face with Load Error: no such file to load — test_helper.

Data structure for Salvatore's Twitter clone in...
If you’re interested in Redis, you should definitely check real-world scenario, @antirez’s tutorial on building a Twitter clone in Redis and PHP. It’s worth to pay close attention how all the information is modeled in Redis, so I have put the overview of the architecture in the following gist:
