Recently I gave ionic a try. Ionic is a "open source front-end SDK for developing amazing mobile apps with web technologies". Since there is also a ionic generator for yeoman it was rather easy to scaffold a project from scratch. It was just a matter of running these two commands to get the generator installed and a new ionic project set-up (assuming you already have yeoman running):
Am 04.09.2015 findet in Arhaus der Shopware Community Day 2015 statt. Ich freue mich mit meinem Vortrag "Offline. Na und?" als Sprecher im Tech Track dabei zu sein.
This article is the last of a three-part series and describes how we optimized the persistence process of bulk data in our code in combination with PostgreSQL. Make sure you covered the first article about how we tweaked PHPExcel to run faster while reading Excel and CSV files and the second article about how we optimized our data processing and reached performance improvements tweaking our code.
A few weeks ago I gave a presentation at the Jenkins User Conference London 2015 about how we have set-up and use Jenkins to power our builds. One idea I mentioned in the talk and I`d like to share now is how we bind our jobs to specific buildnodes. Given the fact that we are doing lots of different projects for different clients we have quite a few buildnodes to cover every use case we need. When we started using Jenkins about 4 years ago we bound every job to a set of specific buildnodes (e.g. buildnode01 || buildnode02). When our setup grew, it was not easy to keep up-to-date to figure out which buildnodes offer which capabilties. In the end this lead to jobs failing every now and then because Jenkins picks a buildnode from the list which does have all the required tools installed, this behaviour I call the "Jenkins law".

Google Chrome 43, which was released in mid-May, has introduced several problems for applications using the ExtJS 4.x or the Sencha Touch 2.x frameworks. For example, the 'painted' event is no longer fired, list components cannot be scrolled, submenu items disappear, and the loadmask no longer plays the spinning animation. This is mainly caused by the removal of the formerly deprecated 'overflowchanged' event. As a reaction, Sencha has offered three overrides, which need to be required in app.js. The overrides can be found here.
A few weeks back I covered a small article about a CSV-Tool optimized for memory usage and additionally tweaking performance.
Am 29.09.2015 und 30.09.2015 findet in Hamburg die Konferenz code.talks 2015 statt. Ich freue mich als Sprecher dabei sein zu dürfen und meinen Votrag "Composer for Corporate Use" zu halten. Der Vortrag stellt dar warum es Sinn macht Composer einzusetzen und wie man Composer konkret im Projektkontext im Unternehmen einsetzen kann.
Recently in an AngularJS project we used the ngTagsInput directive for AngularJS. In the documentation it is shown how to set-up your own function to load the data for the autocomplete functionality. Since our API returned the data in a way that ngTagsInput did not expected it, I needed a way to convert or extract the data before returning it to ngTagInput. It turned out to be quite easy:
I recently covered our Vagrant setup. As mentioned in the blog post we mostly use the Vagrant shared folders setup which unfortunately is rather slow. When searching for alternatives I came across the vagrant-gatling-rsync plugin which seems to work better compared to the built-in rsync support of Vagrant. As it seems the built-in rsync support uses a lot of CPU and disk I/O especially when working with very large rsynced directories. The vagrant-gatling-rsync plugin is designed to work well with such large rsynced folders and performs a lot better. In addition to that you are able to fine-tune the rsync latency via your Vagrantfile which is also a huge win. To install the plugin simply run the following command:
