I thought it was "The candidate I'd most like to see elected".
So many flaws in this poll.

Google is moving more and more utilities to Play Services, which is not open source.
Play Services is not only about Google-related services, it is also about OAuth for instance.
Unknowing developers rely on Play Services, making their apps incompatible with pure-Android devices.

To solve this problem, an Open Source implementation of Google Play Services is being developed:

SharePoint has a vastly superior alternative called Alfresco.

SharePoint is slow, limited and does not respect standards like CMIS: http://cmissync.org/CmisCompat...

If you are looking for an app, ask at http://softwarerecs.stackexcha...

People there will search for apps that fit your particular requirements (features, OS, license, etc).

It is also a good way to find new project ideas, just look at the app requests that have no fit yet: http://softwarerecs.stackexcha...

Item #8 will make your head explode!

Yes, with Anki you can memorize stuff much more efficiently, for long-term.
Available for Linux, Mac, Windows, Android (AnkiDroid), iOS (Anki Mobile).
You can easily sync between devices.
All open source except for iOS.

Yes, ZIM is the best format for this, easy to use on Android too. Full-text search.

And everyone's phone should have Wikivoyage, whole world travel guide in ~1GB (ZIM or HTML files).

Some friendly users translated my free (open source) app to Simplified Chinese.

Where should I upload the APK to reach most of the Chinese market? What 2-3 app markets are the most popular in China? Thanks a lot!

If your company/country wants to create its own private cloud storage, here is the fast way:

1) Set up an Alfresco server on Linux. Enterprise-class, scalable, very customizable.
2) Have users install CmisSync, it looks like a Dropbox client, but syncs with Alfresco (or any other CMIS-compliant server).

Not a cloud service, but this can help Ubuntu users:

Lightweight: no UI apart from the status bar icon, which develops into a menu that shows recent items (optionally in sub-menus). Click on an item to open it in your browser.

The BnF (French National Library) has started doing this in 2006 for a selection of .fr websites.
In 2011 they had 16.5*10^9 files.
They store content on "Petaboxes" made by the Internet Archive.

Anki has free flashcards about any topic you can imagine.
Open source runs on Linux, Mac, Windows, Android, Blackberry, web.
A session is 10 minutes by default, but you can change it to 1 minute.
I use it even when I know I only have 20 seconds (ex: queueing)
