How to install FreeType 2.7 in Ubuntu 16.04 via PPA

Last updated: September 12, 2016

FreeType, a popular font rendering engine, has reached the 2.7 release with a new default mode for bytecode hinting: Subpixel hinting.

In case you are already using subpixel hinting (for example, by using the ‘Infinality patches’ as provided by some GNU/Linux or BSD distributions, or directly from bohoomil.com), be noted that the new mode might provide subtle differences; the code was simplified to make it much faster. If you are used to the old full-pixel hinting, you will see many rendering changes. If you really dislike them, you can disable them at compile time or using the new FREETYPE_PROPERTIES environment variable.

The new release also has improvements to its smooth rasterizer to make it about 20% faster, fixes to fuzzer, handling of raw CID fonts, and various other bug fixes and improvements. See details at FreeType.org.

Install FreeType 2.7 in Ubuntu 16.04:

The Ubuntu 16.04 build has been made into PPA, available for install/upgrade by following the steps below:

1. Open terminal (Ctrl+Alt+T) and run command to add the PPA repository:

sudo add-apt-repository ppa:no1wantdthisname/ppa

Type in your password (no visual feedback) when it asks and hit Enter.

2. To upgrade from a previous release, just launch Software Updater and you’ll see the new release available in the update list:

Or run the commands below to install or upgrade it from command line:

sudo apt update && sudo apt install libfreetype6

Undo:

Simply purge the PPA via ppa-purge will downgrade FreeType to the stock version in Ubuntu 16.04 repository:

sudo apt install ppa-purge && sudo ppa-purge ppa:no1wantdthisname/ppa

Adobe Resurrect Flash for Linux via 23 Beta [Howto-install]

Last updated: December 15, 2016

By releasing the 23 Beta flash, Adobe announced that it starts supporting NPAPI Flash for Linux again.

Today we are updating the beta channel with Linux NPAPI Flash Player by moving it forward and in sync with the modern release branch (currently version 23). We have done this significant change to improve security and provide additional mitigation to the Linux community.

In the past, we communicated that NPAPI Linux releases would stop in 2017. This is no longer the case and once we have performed sufficient testing and received community feedback, we will release both NPAPI and PPAPI Linux builds with their major version numbers in sync and on a regular basis.

Adobe says it will release both the NPAPI and PPAPI (used in Chrome) versions of Flash Player for Linux. However, the NPAPI version will not support or add any advanced features and capabilities, like DRM, GPU acceleration, Stage 3D, etc.

Users who require this functionality are recommended to use Pepper (PPAPI) Flash for Linux.

Install Adobe Flash 23 Beta for Firefox in Ubuntu:

Flash sucks! But since many websites still use it, we have to use flash to view the content.

So far only 32-bit and 64-bit binaries of the 23 release are available for download at the link below:

Flash Player 23 Beta for Linux (NPAPI)

For Linux, the binary is just a file called: libflashplayer.so. To use it, do:

1. Install Flash Player 11.2 from Canonical Partners repository:

Launch Software & Updates, and enable Canonical Partners repository in Other Software tab. Then close it.
Open terminal (Ctrl+Alt+T) and run command to install Adobe-flashplugin:
```
sudo apt update; sudo apt install adobe-flashplugin
```

2. Move the libflashplayer.so file you just downloaded to /usr/lib/adobe-flashplugin/ folder by running the command:

sudo mv ~/Downloads/libflashplayer.so /usr/lib/adobe-flashplugin/

Finally restart Firefox browser and check your flash version:
