I don’t want an app for that

Leider ist der Eintrag nur auf English verfügbar.Scott Adams of Dilbert fame recently posted an article on why your phone interface is a legacy train wreck. He argues that the way we interact with our smartphones goes all the way back to the beginning of desktop computing. In spite of what Apple probably would have us believe - in spite of swiping, tapping and multitouch - we're still largely using our computing devices as if they were a 1987 IBM PC ...

Regular Languages Are … well … Regular

Leider ist der Eintrag nur auf English verfügbar.A few weeks ago I came across an article describing "A regular expression to check for prime numbers". I was intrigued because processes defined by formal regular languages have an inherently linear runtime while the process described is non-linear. This contradicts the definition of regular languages, specifically the Pumping Lemma. So, how is this even possible? Well, the regular expression discussed in this article and the regex framework it's used with makes clever use of ...

GoodUI Datastories

Leider ist der Eintrag nur auf English verfügbar.GoodUI Datastories is a new service that promises to provide companies with tried and tested UI concepts.

The service allows users to submit their ideas including screenshots and ...

FnordMetric and ChartSQL: Create Charts Directly From SQL

Leider ist der Eintrag nur auf English verfügbar.FnordMetric is an interesting new software package that allows you to create good-looking charts (in SVG format) directly from SQL using a query language called ChartSQL. The are quite a few examples available here.

EstiMate – Accurate Crowdsourced Software Development Estimates

Leider ist der Eintrag nur auf English verfügbar.Following up on last week's post I've launched a product site / MVP for EstiMate: Software development effort estimation probably is one of the more difficult tasks in software development. Even the most experienced engineers' estimates are off, too every now and then. Being a somewhat disliked task far too often effort estimation is neglected or done in a rather haphazard way. EstiMate tries to solve this problem with a measurable and reliable method for ...

About the Pitfalls Of Software Development Effort Estimation

Leider ist der Eintrag nur auf English verfügbar.Software development effort estimation probably is one of the most disliked, even feared tasks in software development and computer science in general. However crucial, even the most experienced engineers succumb to common pitfalls from time to time or their estimates are off, too every now and then. This is an especially striking phenomenon because software development effort estimation actually is a well-researched subject that a plethora has been written about. Starting in the 1950s IBM ...

FormatJS: Localize dates and numbers

Leider ist der Eintrag nur auf English verfügbar.Internationalization and localization still is a somewhat difficult problem in software development. FormatJS is a collection of JavaScript libraries that addresses a part of this problem by formatting dates and numbers according to a selected locale. It makes clever use of pluralization and natural language patterns so the output strings read like a natural language utterance instead of a computer-generated string, for example it generates these outputs for 0, 1 and 1,000 items, respectively: "Annie took ...

Monetizing Open Source Software Is Still Hard

Leider ist der Eintrag nur auf English verfügbar.Some weeks ago the guys behind LocomotiveCMS - an open source CMS that's competing with Wordpress - published a sobering article on how they failed making a profit with open source software so far. Their model basically relies on building reputation from their open source work and benefit from community contributions to their software. Their revenue is generated from both doing consulting for LocomotiveCMS and selling hosting services in a SaaS package. Not too unusual a ...
