GIMP Image Editor 2.10.24 Available to Install in Ubuntu 20.04 & Higher

Last updated: April 1, 2021

Before the next major GIMP 3.0, a new maintenance update for the 2.10 series GIMP 2.10.24 now is available to install.

~~Though it’s not officially announced at the moment of writing~~, GIMP has provided the 2.10.24 source tarball & Windows exe for downloading in its website.

And both the Flathub repository and unofficial Ubuntu PPA have updated the packages for the new release.

What’s new in GIMP 2.10.24 according to the release note:

Off-canvas point snapping
GeoTIFF metadata support (georeferencing information embedded within a TIFF file used by map makers)
Many improvements in the metadata viewer and editor
Many file format supports improved: HEIF, PSP, TIFF, JPEG, PNG, PDF, DDS, BMP, PSD
New “Negative Darkroom” operation to simulate enlargement prints from scans of photographic negatives.
The RAW image import now handles darktable 3.6 and over
New Kabyle translation

How to Install GIMP 2.10.24 in Ubuntu:

Method 1: Install GIMP via the universal flatpak package:

If you’re OK with the flatpak package which runs in sandbox, open terminal and run following commands one by one to install it:

1. Firstly add PPA for updated Flatpak package (required for Ubuntu 18.04 only):

sudo add-apt-repository ppa:alexlarsson/flatpak && sudo apt update

2. Install flatpak daemon if you don’t have it:

sudo apt install flatpak

3. Add flathub repository which hosts the software packages:

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

4. Finally install GIMP flatpak package via command:

flatpak install flathub org.gimp.GIMP

NOTE: as flatpak runs in sandbox, it takes much more disk space for run-time libraries.

5. (Optional) If you want to remove the package, run command:

flatpak uninstall org.gimp.GIMP

Method 2: install GIMP via Ubuntu PPA:

For those prefer the classic .deb packages, the unofficial PPA has made the new release packages for Ubuntu 20.04, Ubuntu 20.10, and Ubuntu 21.04.

Due to compile issue, the package for Ubuntu 18.04 is stuck at v2.10.22 at the moment.

1.) Open terminal from system application launcher. When it opens, run command to add the PPA:

sudo add-apt-repository ppa:ubuntuhandbook1/gimp

Type user password (no asterisk feedback) for sudo prompts and hit Enter to continue.

2.) If an old version of GIMP .deb package was installed, upgrade it via Software Updater (Update Manager) utility.

or run apt commands in terminal to install GIMP:

sudo apt install gimp

If you’re going to upgrade the image editor from command line, I’d recommend to RUN this command instead, so to also install the updated dependency libraries.

sudo apt upgrade

3.) (Optional) To restore GIMP to the stock version in main Ubuntu repository, run command to purge the PPA:

sudo apt install ppa-purge && sudo ppa-purge ppa:ubuntuhandbook1/gimp

GNU Emacs 27.2 Released! How to Install it in Ubuntu

Last updated: December 27, 2021

GNU Emacs text editor 27.2 was released as a new maintenance release.

Emacs 27.2 is a bug-fix release with no new features. According to the changelog, it changed the behavior of the user option ‘resize-mini-frames‘. If set to a non-nil value which isn’t a function, resize the mini frame using the new function ‘fit-mini-frame-to-buffer’ which won’t skip leading or trailing empty lines of the buffer.

Emacs now ignores modifier keys when IME input is used. By default, pressing Ctrl, Shift, and Alt keys while using IME input will no longer apply the modifiers to the produced characters, as there are IMEs which use keys with modifiers to input some characters. Customize the variable ‘w32-ignore-modifiers-on-IME-input’ to nil to get back the old behavior.

And the user option ‘tramp-completion-reread-directory-timeout’ is now obsolete.

How to Install Gnu Emacs in Ubuntu:

For those prefer the classic apt repository, keep an eye on the Kevin Kelley’s PPA, though it’s not been updated at the moment of writing.

For those do not like Flatpak and Snap packages, here’s also a step by step guide building Emacs from source tarball.

Emacs is also available as the containerized Snap package, which is however at version 27.1 at the moment.

The community maintained Flatpak package has built Emacs 27.2 for Linux users. Ubuntu 20.04 and higher users can open terminal and run following commands one by one to install it:

Install flatpak framework if you don’t have it:
```
sudo apt install flatpak
```

Add flathub repository which hosts the flatpak packages:

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

Finally install Emacs flatpak package:
```
flatpak install flathub org.gnu.emacs
```

(Optional) To remove the flatpak package, simply run command in terminal:

flatpak uninstall org.gnu.emacs

Firefox 87 Released with SmartBlock to Less Breakage in Private Browsing

Last updated: March 23, 2021

Firefox 55

Mozilla Firefox 87.0 was released today with further efforts on improving user privacy.

Firefox 87 introduced SmartBlock, a new intelligent tracker blocking mechanism for Private Browsing and Strict Tracking Protection Mode. By providing local stand-ins for blocked third-party tracking scripts, you’ll encounter less website breakage while fully protected from trackers.

As today’s web is on the way to becoming https-only and browsers are taking steps to improve user privacy, the 87 browser release introduced new default HTTP Referrer policy instead of ‘no-referrer-when-downgrade’.

It’s ‘strict-origin-when-cross-origin‘ which will trim user sensitive information like path and query string in the URL to protect privacy.

Other changes in Firefox 87 include:

New locale: Silesian (szl)
Improved “Highlight All” feature on Find in page.
Full support for macOS built-in screen reader, VoiceOver.
Disable the Backspace key for browsing back.
Various security fixes.

How to get Firefox 87 in Ubuntu:

For all current Ubuntu releases, the new Firefox package will be published in Ubuntu security & updates repositories in the next few days.

At that time, you can easily update the web browser through Software Updater (Update Manager)

Audacity 3.0.0 Released! Now Save Project into Single .aup3 File

Last updated: July 4, 2021

The Audacity audio editor 3.0.0 was release as a new major update a day ago.

Audacity 3.0.0 features .aup3 project format. The audio project was previously saved as large number of small data files, with an ‘.aup’ file to coordinate the lot. Now it saves project as the new all-in-one-file aup3 file format.

According to the Privacy Notice, Audacity may COLLECT personal data necessary for law enforcement, litigation and authorities. And it dissuade those under 13 years old from using the App.

It is incompatible with the GPL license. USE IT AT YOUR OWN RISK!

Working with the new .aup3 projects editing audio should be a little faster than before, however, finishing and closing a project at the end can be quite a lot slower.

You can open your older .aup projects in the new version, where they will be converted to the new .aup3 format.
