Every developer have to deal with backups. In the linux world the most used tool is probably rsync, and often it is run through rsnapshot, which lets you create incremental snapshots of your directories.

You could solve this ...

Managing location related tasks inside a react-native project can be quite frustrating. I've encountered many problems, for example when getCurrentPosition was always returning me a cached position object, despite of my configurations. For this reason I wrote a getLocation function that tries to incapsulate all the code needed to get a reliable position with a fallback to low accuracy mode.

But getting the real location is only a part of the story, which consists of many other tasks:

• authorize the app to access location
• enable location setting if disabled
• inform the user about what it's going on
• ...

So I finally decide to wrote a reusable component which tries to manage all this stuff in one place, which makes use of ...

I've had many problems with react-native geolocation module.

In particular I faced a weird behaviour of the getCurrentPosition method: while the world was lamenting timeout problems, probably due to the fact that gps tracking is not fast at all in closed spaces, my problem was that with highAccuracy set to true, the returned value was always a cached one, no matter how I set maxAge option.

If your problem is a timeout problem, then you can just call getCurrentPosition with ...

I always use django-ckeditor in my web site projects when I need an html editor. CKEditor is a nice tool, highly customizable, which produces a well formatted html. Here at Otto srl there was the need to include custom app's contents inside the editor in an easy way, since the tool has to be used by unexperienced people.

I approached these requirements developing a custom CKEditor plugin, which can communicate with django apps async through ajax requests. Every app can ...

This was the first time I had to manage serious translations for a react-redux project. I use to develop my applications starting from the awesome react-redux-starter-key by davezuko.

This starter kit doesn't include i18n support out of the box, so some work is needed. I followed this article from freecodcamp and changed things a bit, so let's start.

I was a happy developer using django-suit for all my working projects. Now django-suit v1 is becoming a bit oldie, it is based on bootstrap 2.3, and rewrites so many templates that its compatibility with some other apps begins to suffer (i.e. django-filer). It's a shame, it was in my opinion the best admin app overthere.

I know django-suit v2 is on stage, at the moment of this writing it is in development, and I'm quite sure it'will ...
