a better mousetrap #2: RESTing HATEOAS

Eventually a rather short thought relating to my attempt trying to, well, build a better mouse trap. Maybe in course of exploring things and slowly growing a technical environment into something new, there’s always the chance of discovering a show-stopper to immediately prove a given approach limited or even wrong altogether, but at the moment, I am pretty much entertained by following HATEOAS and HTTP ‘ideas’ for building an (external, internal, whatever) system interface all anew. Why?

a clueless start to node.js

node.js is a technology that has been on my “to-try” stack of technologies for quite a while now. There has been quite some fuzz out there recently regarding this framework, and as so far I wanted to have a closer look on what’s possible in JavaScript outside the browser, anyway, it seemed a good reason for dealing with something “new” just for the sake of it, even without immediately having any meaningful use cases at hand… Read on. :)

modeling, technologies and culture

Looking back at yesterdays Dresden Eclipse Indigo demo camp, I ended up with a couple of thoughts in my mind, both related to the technologies demonstrated there, and related to how to make meaningful use of them in a real-world environment. Overally, this demo camp event mainly was dominated by topics related to modeling tools and concepts on top of Eclipse technology – hardly a surprise knowing that itemis, the company behind tools such as XText, also appeared as main sponsor and organizer of this evening. Consequently, XText also appeared on the agenda in its latest EMFText and how to easily build (or, better, “have around”) an Eclipse integrated debugger for EMFText based domain specific languages at no additional costs. Running a DSL interpreter and doing debugging just the way you’d do it in Java code surely is an interesting experience. Not even talking all too much about ProR integrated with XText for the purpose of capturing requirements in a somewhat formal way. In some situations, this is just what you want or need, and problems to eventually be solved by using these tools are obvious almost immediately…

a better mouse trap #1: persistence, document storage and couchdb

Ever considered building a better mouse trap? Well. I do, actually, each and every day anew. I will leave out most of the more in-depth considerations related to this, as for now they don’t matter – the only thing worth knowing, initially, is that the process of “migrating”, “updating”, “rebuilding”, … an existing, fairly complex application system is something that is painful beyond all imagination, and this even while “just” considering the mere technical effects and aspects of this procedure…

Locked in?

Es dürfte dem einen oder anderen nicht verborgen geblieben sein, daß ich das Gros meiner Tage damit verbringe, Software in einer In-House – Umgebung gleichermaßen zu betreiben, zu entwickeln und auch, irgendwie, in ihrer langfristigen Ausrichtung und Entwicklung zu planen. Ich bin seit ehedem Anhänger der Idee “Freier Software” (mit großem “F”, wie in “Freie Rede”, nicht wie in “Freibier”…) oder, wenn pragmatischer, technischer, zumindest des Ansatzes von Open-Source-Software-Entwicklung, im Wesentlichen aus denselben Gründen (offener Umgang mit “gemeinschaftlichem” Wissen, Respektieren der Rechte und Interessen aller Beteiligten, Lösen von einem starren und meist falschen “Produzent”/”Konsument”-Verhältnis und so weiter und so fort). Im Alltag indes zeigt sich, bisweilen, daß diese Frage zwar interessant und relevant ist, aber letztlich nicht weit genug springt, um gewisse Probleme zu lösen, und auch nicht in jedem Fall allein geeignet ist, um “Lock-In”-Effekte, die übermäßige und faktisch nur extrem schwer lösbare Bindung an bestimmte Produkte oder Hersteller, von vornherein zu minimieren.
