Root access in Android as of 2018

I already wrote about the topic “rooting of Android” in 2013. Since then the direction of Android itself changed a lot.

Things which where not very popular five years ago are now quite normal: films are being watched on mobile devices with services such as Netflix and games like Pokémon GO generate huge sales (by the end of 2017 about 890 million USD). For the providers of such services it is of course important that the data of the apps is not accessible by third parties – for example to protect DRM mechanisms.

Another area are payment services, such as Google Pay, which got introduced in 2015 – and again, it is important that no third party can access confidential data.

Three years smoke-free

As today’s the World No Tobacco Day, it’s appopriate to mention it: I’ve been smoke free and happy with it for three years now :-). In May 2015, I smoked the last cigarette and live since then smoke-free. Aside from the health aspect, I also grossly estimate to have saved well over 5000 EUR not spent on cigarettes. Money, which I can use in a better way for other things.

If you are interested, I also wrote some other articles about my experience (in German only yet): Der lange Weg zum rauchfreien Leben und Ein Jahr rauchfrei.

 

Segmented type displays to play with

Probably everybody knows public displays which are composed of segmented characters.

On https://aresluna.org/segmented-type/ you find an emulator for that which displays different variations from 8 to 93 segments per character. You can type any text on your own  and select different display variations with the displayed text.

Does anyone still remember the time when the first pinball machines started using 14 segment displays which allowed to show not only the current scores but also any kind of messages?

Experiences with NextCloud

Many years ago I already had look at OwnCloud, which was first released in 2010 and claimed to offer an alternative to commercial services like DropBox or Google. The idea was good, only the implementation and the security was lacking at the beginning, which had kept me back from permanent use.

For exchanging files I later discovered Seafile as an alternative. For addresses and appointments I used Baïkal to synchronize the data between my Android devices and different computers with CalDAV and CardDAV. Added to this is Roundcube as a webmail client with an extension for using the Baïkal address book via CardDAV.

Although this constellation basically worked, there were some drawbacks: a browser-based calendar does not exist at all and Baïkal has no longer being actively developed for some time – the latest version is from August 2016 (see release page at Github).

Periodical 1.0

After a longer break I finally extended “Periodical” by the functions which already have been planned for a while:

  • single days can be added to a period or removed from a period individually.
  • days of the period can be marked with an invididual intensity.
  • the calendar shows the current day of the cycle.
  • you can add notes and symptoms to every day in the calendar.

The new version is available as download or at Google Play. F-Droid will follow soon.

MouseJack and Logitech

If you are using wireless mice and keyboards you should be aware of the risks. Also see this article at Computerworld.

At least Logitech provides a firmware update which fixes the problems:

Announcement at Logitech concerning “MouseJack”

The program also checks if there is an update needed at all. So I found out that even the Unifying Receiver of a new keyboard (K270), bought in January 2018, was still shipped with an outdated firmware.

Only when the update tools displays a message that all found devices are up to date, there is no risk.
