OpenSUSE Linux on Windows 10 (!)

Before doing this, you might want to remove the early version of Ubuntu for Windows by running

lxrun /uninstall

(source). Then, enable Linux sub-system in Windows by running

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

as Administrator in PowerShell. After this, simply install your desired Linux distro from Windows Store (source). Finally, here is the link to OpenSUSE.

This
should help with a bunch of Open Source software that was struggling to
publish a Windows version, or compiling them yourself.

Bye, bye Resharper

The last function I missed in Visual Studio, that was keeping Resharper on, was locating a file by name or by class name.



However, it turns out that the feature already exists, as explained here:

https://visualstudioextensions.vlasovstudio.com/2017/06/14/new-code-navigation-shortcuts-in-visual-studio-2017/

It is called 'Go to All' and is easy to assign to the familiar Ctrl+T shortcut.



Good bye, slowness.

In addition, notification channels need to be created for any notifications on API >= 26. Notification channels are useful. They allow grouping of notifications so that end users can disable or enable them as they see fit.

NextCloud on Raspberry Pi

Considering the new Raspberry Pi has mobile and Wi-Fi interfaces built-in, it makes a fantastic candidate for being a home access point as well as a NextCloud server.



Now there is also an official project, a Raspberry Pi image of the latest stable NextCloud release:

A wonderful candidate for the next winter hobby project.

Use your SD card as Internal Storage on a Samsung phone

It requires some tinkling because Samsung disabled this native Android functionality (wtf?!).

In any case, the method works and my phone can breathe again.

Instructions

Edit, 2018-03-19: Now the phone provides the option to add an SD card as an internal storage. However, be careful to perform the data migration after formatting the card. This will move the data and make pointers for the data folders. Otherwise, you may end up with the card formatted but not being used by the system as the data folders still point to the phone's memory card.
