I just released lettuce 3.4.Final and lettuce 4.1.Final. You can find the full details about 3.4.Final and 4.1.Final on Github.

These release contain numerous features and bugfixes. Lettuce introduces reusable client-resources, an EventBus, client metrics, and support for newly introduced commands. This versions work with Redis 3.2 RC3 but Redis expects a change in the format of CLUSTER NODES. So watch out for a new release of lettuce as soon as Redis 3.2 RC4 or a final is released.

The Wiener process is a continuous-time stochastic process named in honor of Norbert Wiener. It’s commonly used to represent noise or financial development with a random component.

The geometric brownian motion can be calculated to visualize certain bounds (in quantiles) to hint about the absolute range.

I read The full stack developer is a myth story written by Scott Hadfield the other day. Once I got through the post, I realized a couple of things. The first major point is, there’s no uniform understanding what full stack developer means. More issues are the views of the commenters to the article and the opinion of companies mentioned in the article. It shares my experience how companies deal with so-called full stack developers. This article will clarify that view. Let me give you some context before I come back to full stack developers.

I wanted to build something cool and scary for Halloween. Here in Germany Helloween is just about to become a trend. Meet the ScareOS, a thingy to spice up Halloween.

Features

  • Moving eyes (object tracking perhaps in version 2 - have to figure out how to integrate motion tracking)
  • Discovers if someone is around by using a ranging sensor
  • Plays Halloween sounds when it's awake
  • Sleep state if no one is around for a while
  • Whines when someone comes too close

The plan for this year's Halloween: Built a scary thingy based on Arduino. Halloween is over now.

I built an Arduino-backed jack-o'-lantern with LED matrix panel eyes, an ultrasonic ranging sensor for the nose and a sound module to play scary Halloweenish sounds. It is impressive to see the whole thing assembled. They eyes move around, the thing can go into sleep if no one is around and wake if someone comes close to the pumpkin.

lettuce 4.0.Beta2 features ReadFrom Settings. ReadFrom affects how lettuce routes read operations to the members of a Redis Cluster.

By default, lettuce routes its read operations to the master node. Reading from the master returns the most recent version of the data because write operations are issued to the single master node. Reading from masters guarantees strong consistency.

You can reduce latency or improve read throughput by distributing reads to slave members of the Redis cluster for applications that do not require fully up-to-date data. ReadFrom is set per connection, meaning you can use different connections with different ReadFrom settings.
