Rudder fall 2018 bug crunch

Middle of Autumn is that kind of period of the year where you look back at the past month, the lovely spring, the hot summer, the crazy La Rentrée, and wonder… Why on earth are there so many bugs open in our ticketing system? Especially so many little things, not the kind that cause serious […] Read more

RUDDER 5.0 is out!

The initial RUDDER model consisting of a single software block which includes all features, thus imposing a greater and greater complexity on all of our users, has reached its limits. We have now reached a sufficient understanding of the domain, its challenges, and the way RUDDER is used, to make us realize that this all-in-one […] Read more

RUDDER 4.3 – Focus on the ‘Technique Parameters’ feature

RUDDER aims at providing an easy to use configuration management solution. One of the key design choice that allows it is the separation of configuration according to different abstraction levels: Techniques which are configurable configuration templates Directives which are ready-to-use instances of a technique Directives are then linked to machines (using rules and groups). Techniques […] Read more

RUDDER 4.3 – Focus on the ‘API rights’ feature

Since RUDDER 2.7 (Almost 5 years ago!), we provide an API that gives you access to almost all data and features from RUDDER so you can build your own scripts and integration and make RUDDER more integrated in your IT environment (more details about the API here: https://www.rudder-project.org/rudder-api-doc/), there was one flaw in our design: […] Read more

RUDDER 4.3 – focus on the ‘node lifecycle’ feature

Until Rudder 4.3, there wasn’t any notion of node lifecycle in Rudder, and so no native way to differentiate between different states of a node. That used to cause some troubles, for example when nodes are no longer connected to a Rudder Server (typically for a maintenance period). So far, in such a case, the […] Read more

RUDDER 4.3 – focus on the ‘properties by inventory extension’ feature

Rudder directives management can be quite complex when dealing with heterogeneous nodes, needing different configurations. In order to limit the multiplication of directives we could use variables or node properties to pass different parameters and try to factorize some code. The 4.3 release comes with a new feature to expand the node inventory with arbitrary […] Read more

The new RUDDER agent for Windows is out!

To deal with increasingly complex infrastructure growth, reliability and security issues, the establishment of a continuous approach into IT automation tends to progressively become the obvious answer to these evolutions. This complexity results from the infrastructure manager struggle to handle a double heterogeneity : technlogy diversity and team members skill disparity. However, to take advantage of all its […] Read more

Per-file compilation time in a Scala/Maven project

Where is Moore when he is needed ? Scala is a fabulous language, the tooling is now quite good, but it still have one big drawback… One that makes wonder if XKCD 303 wasn’t drawn with Scala in mind. Scalac takes forever to compile anything. In a non trivial project, that forever means (tens of) […] Read more

Scala Pitfalls For Java Refugees (SP4JR) #0: because what you think you know might be a hammer waiting for a thumb

Java++… or something else? This article is the first of what should be a really short series, because as you know, Scala is just Java++, and so the differences between the two are almost non-existent. OK, I don’t think I could have said more wrong things in one sentence, so now, let’s be serious! Scala […] Read more

Set up Eclipse workspace in RAM

In the last article, we covered basic optimization paths for Eclipse. But it remains that Eclipse spend an awful amount of time performing I/O, reading and writing big amounts of (often small) files – and you can’t imagine how numerous theses files are. Of course, there is all the class resources file you are editing […] Read more

Java LDAP SDK for SyncRepl replication showcase

Java LDAP reborn As you may know, I’m rather fond of the LDAP protocol and its open source server and client implementations. But I’m also found of the JVM, and in a not so far past, the only maintained Java LDAP SDK was Sun’s LDAP-JNDI, which is at best a call for masochists to make […] Read more
