From 27th to 30th of December there will be the [31st Chaos Communications Congress](https://events.ccc.de/congress/2014/wiki/Main_Page).

I will be attending the event for the first time. I am very excited about all the [Talks](http://events.ccc.de/congress/2014/Fahrplan/), [Assemblies](https://events.ccc.de/congress/2014/wiki/Static:Assemblies) and great people I will see and meet there. During the Congress I will update this post with my impressions of the event.

For all of you who will not be there, the CCC VOC will provide [Streams](http://streaming.media.ccc.de/) of all the talks.

__Update:__ Of course I did not update this post during the congress. Shortly: It was _really awesome!_ For some impressions check my [Twitter Feed](http://twitter.com/jonas_w) from 27th-30th of Dec, 2014. You can find the recordings of the great talks [here](http://media.ccc.de/browse/congress/2014/).

 

Enable Continuity on MacBook Pro Early 2011

2 min read

Today I was able to to enable [Continuity](https://www.apple.com/ios/whats-new/continuity/) on my early 2011 MacBook Pro. As Continuity depends on Bluetooth Low Energy which is part of the Bluetooth 4.0 standard and the early 2011 MBP does not have a BT4.0 chip, my MacBook did not support Continuity by itself when OSX Yosemite was released.

So I ordered a [new Airport/Bluetooth Card](http://www.aliexpress.com/item/Free-Shipping-MD101-MD102-WiFi-Airport-and-Bluetooth-Card-for-Macbook-Pro-Unibody-A1278-2012/2033102338.html) for my MacBook Model and replaced the old one. Here I got help from an [iFixIt-Tutorial](https://www.ifixit.com/Guide/MacBook+Pro+13-Inch+Unibody+Early+2011+AirPort-Bluetooth+Board+Replacement/5131). The replacement was not too hard to perform, only one time when you have to peel some tape from the card tray I wasn't sure not to break anything. But after reassembling the Laptop without loosing any screws I was able to boot the MacBook and see that the new card was recognized as expected.

The only thing left to do to enable Continuity was to start the [Continuity Activation Tool](https://github.com/dokterdok/Continuity-Activation-Tool) by dokterdok, a greatly maintained github project. The author of the tool is currently working on a version to use with BT4.0 USB-Dongles instead of the internal wireless card.

Now I can use Handoff (continue to work in the same App across several devices), Instant Hotspot (use my iPhone's internet connection without even touching the phone) and AirDrop (direct file transfer between iOS and OSX) on my 3.5 year old MacBook Pro.

 

ownCloud

2 min read

I just decided to setup my very own [ownCloud](http://owncloud.org/) to get rid of Apple and Google for my personal Calendar and Contact Sync. Gladly the great team of [uberspace](https://uberspace.de/) has already set up a [Wiki](https://uberspace.de/dokuwiki/cool:owncloud)-page describing how to install and configure it on their servers. (Installation is in fact just running a php-script)

After setting up an admin-user, you're in. By default you have a view for all your Files in your ownCloud as well as special views for images and documents. When you install the [ownCloud Desktop Sync Client](http://owncloud.org/install/) you can use it just like Dropbox or Google Drive: Place any Files in the ownCloud Folder and they will automatically be synced.

Primarily I want to use ownCloud to sync my calendars and contacts between my MacOS- and iOS-Clients. All you have to do for this is:

* Export Calendars as .ics-files and contacts as .vcf-files
* Place these files in your ownCloud Folder and wait for their upload
* In your ownCloud webfrontend open each file and add its contents to the calendar/contacts apps.
* In the settings of the apps you can find the urls to your new CalDAV/CardDAV Server. They look something like this (for calendar, contacts is slightly different):
> https://DOMAIN/OWNCLOUD_FOLDER/remote.php/caldav/principals/USERNAME/
* Add these URLs to your *Internet Accounts* in the MacOS *System Preferences* alongside your ownCloud credentials.
* Check if the data has been downloaded to your calendar/contacts.app and delete your old Google/iCloud subscriptions.

OwnCloud has many more great features, for example an RSS-Reader. Let's hope that mobile RSS-Readers like [Reeder](http://reederapp.com/) will support ownCloud soon.
