New (free) resource for stock photos

Shopify launched a new project called „Burst“ that you can add as a new stock photo resource. The service provides „Free photography for entrepreneurs“ as it is described on Burst’s homepage.

The photos come along with a Creative Commons Zero license, which means you’re allowed to basically do everything with the photos (see details on Burst’s FAQ). Tho you’re still allowed to credit the author 😉

Mac Apache not starting because of PHP standard module

If you have a problem with Apache not starting although there’s no error log entry (and sudo apachectl configtest also doesn’t help), try
sudo apachectl -X
That way the debug mode is enabled and you get to see every problem that prevents Apache from starting. Even if it’s a PHP warning that is caused by the standard PHP module:
Warning: PHP Startup: Unable to load dynamic library '/usr/local/php5/lib/php/extensions/no-debug-non-zts-20160303/' - dlopen(/usr/local/php5/lib/php/extensions/no-debug-non-zts-20160303/, 9): Library not loaded: /usr/local/php5/lib/libcurl.4.dylib

If you encounter that warning / error, comment the php5_module line out (to find in /etc/apache2/httpd.conf):
#LoadModule php5_module libexec/apache2/

The reactive programming paradigm

I think I’m getting old. There’s a new programming paradigm floating around (for four years) which I’ve barely heart of. And now that I know it exists (by „stumbling“ over it via learning Angular 2) I can’t imagine coding without it ever again. There’s even a manifest (see:

Reactive programming focuses on the change of a state over time not just on the state in that particular moment.
The inevitable advantage of that kind of programming is that we actually don’t need to take care of the new state but let the application handle everything necessary (like seen in Angular 2’s Two Way Data Binding).

As debugging is also affected by the paradigm it was very unfamiliar to work with streams and observables at the beginning. You can’t console.log your way from everywhere in the application. You have to follow the „flow“ (i.e. stream) to get the desired information. But once you got used to it, working reactive feels more natural than the old approach.
