Some years ago I moved into my own home. At that time I had the idea to setup christmas lights in our garden. Maybe not as large as Carson Williams setup, but at least something. And well, you know, it grew from year to year. Now I came to the point where I want give you control over the lights.

Some time ago, I wrote about finding the right NoSQL data store. It depends pretty much on what you want to do. After a series of tests I finally have some results I want to share. My goal: Find the most appropriate NoSQL data store for our project's use case.

Requirements

The requirements is to parse XML files which are stored on a storage system and put relevant keys into a data store to be able to find the data again. It's a sort of index. The data is hierarchical with two levels (master and detail). The data stream is continuous and there is a lot of data (not big data). 10's of TB's.

lettuce 3.0 was released. Lettuce is a scalable thread-safe Redis client providing both synchronous and asynchronous connections. Multiple threads may share one connection provided they avoid blocking and transactional operations such as BLPOP, and MULTI/EXEC. Multiple connections are efficiently managed by the excellent netty NIO framework. Support for advanced Redis features such as Sentinel, Cluster and Redis data models are included.

Some of the major changes are:

  • Support for the latest Redis commands
  • Redis Cluster support
  • Redis Sentinel support
  • Upgrade to netty 4.0.19 (from netty 3.x)
  • CDI and Spring support
  • Streaming API
  • Listenable Futures (using Guava) for true async operations
  • Tons of bugfixes, tests and documentation

Lettuce 3.0 is a fork of original lettuce@wg with preserved packages and mostly the same API. The original lettuce is no longer in active development.

What's next?

My plan is to keep up with tight Redis development and to integrate the new fork into Spring Data Redis. Redis Cluster has to get mature, and the current implementation has to prove in production.

Elasticsearch, Logstash and Kibana are widely used for log management. I wrote in earlier posts about submitting application logs towards logstash. Let’s approach access logs today.

A while ago I was inspired by the story of Gameboy to SuperPiBoy, a Raspberry Pi within a Gameboy case. This was reason enough to start my own project. I was owner and a fan of a Gameboy at the age of 10.

My RaspiBoy features:

  • 3.5" TFT display
  • 32GB solid state drive
  • RasperryPi inside
  • three more buttons
  • WiFi
  • Logitech Unify receiver
  • Original Gameboy controls
  • External Volume control with Speaker and stereo audio connector

A choice of decision for a NoSQL data store depends on several factors. It's no longer a hot-or-not decision. The big hype is over, reality comes back now.

I'm progressing on my RaspiBoy project. So I'm getting in touch with a couple of yellowish Gameboy cases and game cartridges.

Older game console cases, such as Gameboy, Nintendo NES, Commodore 64 and so on, start yellowing. The more sun they get the more yellow they become. There is finally a solution (beside sand paper and overpaint) to de-yellowize them. It's called Retr0bright.
