The holiday season is almost over, so it’s high time to plan the next one!

Since sandboxing agents is recent hobby of mine, I’ve been looking at the new Docker Sandboxes (sbx), and how they compare to Sandcat.

My goal is to create an environment where I can let Claude Code work autonomously on an issue: write tests, code, iterate on the solution, and finally create a PR.

Why learn another editor in the first place?

Most Java/Scala/Groovy project depend on a number of libraries, these libraries depend on other libraries, and so on for many levels deep.

I recently wrote about Event Sourcing and Free Monads.

Recently we released MacWire 2.0, with a number of new features and general code cleanup.

If you haven’t yet heard about Supler, it’s a Rapid Form Development library, working with your favorite Javascript frontend and Scala backend frameworks.

A couple of days ago MacWire 1.0 was released!

It’s been some time since the last release of Supler.

Quicklens is a small library which allows to modify deeply nested fields in case classes e.

TL;DR: Quicklens: modify deeply nested fields in case classes, e.g.: modify(person)(_.address.street.name).using(_.toUpperCase).

It’s 2015.

Supler is a library which makes writing complex forms easier.

A couple of days ago MacWire 0.8.0 got released.

Supler aims to make complex web forms development easier, without tying you to a web framework.

In the last two posts on reactmq, I described how to write a reactive, persistent message queue.

Let’s face it.

MacWire is a Lightweight and Nonintrusive Scala Dependency Injection library.

Some time ago I wrote how to implement a reactive message queue with Akka Streams.

An updated and extended version of this post is available on SoftwareMill’s website.

SQS, Simple Message Queue, is a message-queue-as-a-service offering from Amazon Web Services.

Docker is great for running isolated containers on a single node.

Update 15/09/2014: introduced API changes from akka-streams 0.7.

We have recently released version 2.0 of Codebrag, our code-review tool.

Recently I took part in the Discrete Optimization class at Coursera.

Docker is a pretty new, but very exciting project; with Docker you can create lightweight, self-sufficient containers with any application inside, and later run the containers on a variety of hosts.

Indoor positioning is a very popular topic recently, mostly due to the iBeacon technology promoted by Apple, and adopted by other vendors.

The first Makerland is over – if you read only the first sentence of this blog, the conference was great, watch out for the second edition (hopefully there will be one)!

There’s a lot of hype about “big data” and a general trend to try to apply Hadoop to almost every problem.

I would like to describe a pure-Scala approach to modularity that we are successfully using in a couple of our Scala projects.

Recently I’ve been doing some simple face detection in a Scala-based project.

iBeacons are certainly a trending topic recently.

A couple of weeks ago I read about Elm, a new functional language, which compiles to JavaScript and HTML.

I just came back from the BuildStuff conference in Vilnius, Lithuania (actually this was almost a week ago, but I was writing that back at the airport ;) ).

Apache Mahout is a “scalable machine learning library” which, among others, contains implementations of various single-node and distributed recommendation algorithms.

Recently we’ve been implementing a recommender system for Yap.TV: you can see it in action after installing the app and going to the “Just for you” tab.

Interceptors are very useful for implementing cross-cutting concerns.

This year I had the chance to attend JavaZone 2013.

Macro Annotations are a new type of macros, which are one of the candidates for inclusion (see also comment by Eugene below) in the upcoming Scala 2.

The most recent release of MacWire (0.4) (a Scala macro to generate wiring code for class instantiation, DI container replacement) comes with new utilities which make it easier to integrate with frameworks which require by-class instance lookup.

Veripacks already allows to specify and verify which classes should be visible outside of a package (in a package-transitive way) as well as require importing and import packages within a project.

I was recently working a bit with Twitter’s Storm, and it got me wondering, how does it compare to another high-performance, concurrent-data-processing framework, Akka.

Factories are useful when we need to create multiple instances of a class at run-time, usually providing some parameters, but still without using new explicitly; we want to make some complex object creation abstract.

ElasticMQ 0.7.0, a message queueing system with an actor-based Scala and Amazon SQS-compatible interfaces, was just released.

Akka is a great tool for writing distributed applications.

MacWire generates new instance creation code of given classes, using values in the enclosing type for constructor parameters, with the help of Scala Macros.

One thing that I miss in GitHub is the ability to get e-mail notifications on each push/commit.

Using Dependency Injection is almost a standard when developing software.
