Cawbird – Native Linux Twitter Client for Gnome 3 (‘Corebird’ fork)

Last updated: November 28, 2019

Cawbird is a modern lightweight Twitter client for GNOME 3. It features inline image and video preview, creation of lists and favorites, filtering of tweets and full text search.

“Cawbird is a fork of Corebird, which became unsupported after Twitter disabled the streaming API. Cawbird works with the new APIs and includes a few fixes and modifications that have historically been patched in to IBBoard’s custom Corebird build on his personal Open Build Service account.”

Cawbird has the following limitations due to changes in the Twitter API (imposed by Twitter, not the fault of the client):

  • Cawbird will update every two minutes
  • Cawbird does not get notified of the following, which will be refreshed on restart:
    • Unfavourite
    • Follow/Unfollow
    • Block/Unblock
    • Mute/Unmute
    • DM deletion
    • Some list changes

How to Install Cawbird in Ubuntu:

The easiest way is simply search for and install cawbird from Ubuntu Software.

This is a Snap package runs in sandbox. And it’s maintained by the community.

For those prefer native .deb package, go to the developer maintained repository at the link below:

Select Ubuntu, then click ‘Grab binary packages directly‘ and download the .deb package for your system.

Finally install the .deb via Gdebi package installer (available in Ubuntu Software) and enjoy!

[Quick Tip] Speed Up Installing (Downloading) Snap App in Ubuntu

Last updated: April 24, 2024

This simple tutorial shows how to speed up the downloading process of snap application package by associating IP address with the snapcraft server in Ubuntu.

Snap is a containerized package format, that makes many great applications (e.g., Spotify, Skype, the latest Blender, and more) easy to install in Ubuntu 18.04 and higher.

However snap is LARGE in file size. Due to slow international network speed, downloading a snap in 20MB even take more than half an hour in my case.

1.) Open terminal either via Ctrl+Alt+T keyboard shortcut or by searching for ‘terminal’ from application menu. When terminal opens, run command:

dig fastly.cdn.snapcraft.io

In the terminal output, copy the IP address under ‘ANSWER SECTION’:

2.) Then run commands to edit the hosts file:

sudo gedit /etc/hosts

Type user password (no asterisk) when it prompts and hit Enter.

When the files opens in gedit text editor, paste following line:

151.101.42.217 fastly.cdn.snapcraft.io

Replace the IP address with which you got in step 1, and finally save the file.

That’s it. Enjoy!

Linux Kernel 5.4 Released! How to Install it in Ubuntu

Last updated: November 25, 2019

Linux 5.4 Kernel was released today. Here’s how to install it in Ubuntu and Linux Mint.

Linus Torvalds announced the 5.4 Kernel on lkml.org:

“Not a lot happened this last week, which is just how I like it. And as expected, most of the pull requests I got were for the 5.5 merge window, which I’ll obviously start working through tomorrow.”

Linux 5.4 Kernel brings a lot of new hardware support，including AMD Arcturus GPU, Navi 12 and Navi 14 GPUs, AMD Dali and Renoir APU support，Intel Tiger Lake “Gen 12” graphics，Qualcomm Snapdragon 855 SoC, Intel Ice Lake Thunderbolt support. The new release also features Logitech Linux LOCKDOWN LSM, Lightspeed receiver support, Microsoft exFAT support, and a plethora of other new features and improvements.

How to Install Linux Kernel 5.4 in Ubuntu:

The mainline kernel packages for Linux 5.4 are available for download at the link below:

Depends on your OS type, download and install the packages in turns:

  1. linux-headers-5.4.0-xxxxxx_all.deb
  2. linux-headers-5.4.0-xxx-generic(/lowlatency)_xxx_amd64.deb
  3. linux-modules-5.4.0-xxx-generic(/lowlatency)_xxx_amd64.deb
  4. linux-image-xxx-5.4.0-xxx-generic(/lowlatency)_xxx_amd64.deb

Select generic for common system, and lowlatency for a low latency system (e.g. for recording audio), amd64 for 64bit system, i386 for 32bit system, or armhf, arm64, etc for other OS types.

Alternatively you can download and install the kernel binaries via terminal commands ( open terminal via Ctrl+Alt+T):

For 64-bit OS:

cd /tmp/

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4/linux-headers-5.4.0-050400_5.4.0-050400.201911242031_all.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4/linux-headers-5.4.0-050400-generic_5.4.0-050400.201911242031_amd64.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4/linux-image-unsigned-5.4.0-050400-generic_5.4.0-050400.201911242031_amd64.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4/linux-modules-5.4.0-050400-generic_5.4.0-050400.201911242031_amd64.deb

sudo dpkg -i *.deb

No 32-bit packages so far as build for 32-bit failed.

Once installed, restart your computer and enjoy!

Uninstall Linux Kernel 5.4:

Restart your machine and select boot with the previous kernel in boot menu ‘Grub2 -> Advanced Option for Ubuntu’. Then run command to remove Linux Kernel 5.4:

sudo dpkg --purge linux-image-unsigned-5.4.0-050400-generic

Glimpse Image Editor (GIMP Fork) 0.1 Available to Install in Ubuntu

Last updated: November 24, 2019

Glimpse, a downstream fork of the GNU Image Manipulation Program (GIMP in short), released version 0.1 a few days ago. It can be installed in Ubuntu 18.04 and higher via either Snap or Flatpak.

Due to the problematic word “gimp”, Glimpse forked the well known image editor so there are no potential barriers to using the software in businesses and educational institutions.

“If English is not your first language, then you may not have realised that the word “gimp” is problematic. In some countries it is considered a slur against disabled people and a playground insult directed at unpopular children. It can also be linked to certain “after dark” activities performed by consenting adults.

…”

Glimpse 0.1 is based on GIMP 2.10. So far they just look like same application with different names (in my own opinion).

How to Install Glimpse in Ubuntu:

For Ubuntu 18.04 and higher, you can easily install the community build Snap package of Glimpse image editor from Ubuntu Software.

If you’re familiar with command line, run command in terminal to install the Snap package:

sudo snap install glimpse-editor

The software also offers official Flatpak package available in Flathub repository:
