PeerTube Cannot Play Video? Install FFmpeg!

Bismillahirrahmanirrahim.

Previously, I don’t know why my Firefox (latest version on latest Fedora Rawhide) cannot play videos on PeerTube. Yes, you’re correct, the video I watch is Introducing GNOME 3.30 “Almeria”. The web says “No compatible source was found for this media” but clearly the commenters seem to be able to play the video so this problem is only for me. Then I installed FFmpeg (from RPMFusion “free” of course) and finally videos playing without error on Firefox. It works! However, it’s Firefox 62 and ffmpeg 4.0.2 on Rawhide I got at 15 September 2018. Thanks Framasoft and PeerTube Project, Mozilla and FFmpeg Project, thanks Fedora community, and thanks GNOME Project for making great video of 3.30 available at PeerTube.

If you want to know more about PeerTube, a federated “YouTube” that is free software, read on official website and FAQ.

Install GNU/Linux on External SDCard with Btrfs

Bismillahirrahmanirrahim.

Some reviews I’ve written on UbuntuBuzz lately about Bionic Beta 2 flavors, are, all installed on a 16GB SanDisk SDCard using a USB card reader. Not only Bionic, but Trisquel prerelease version is also installed there. One common problems among all systems I’ve installed there is they are all broken after one or two times of using. Broken here means failure in the filesystem, aka, corrupted, aka fsck checking needed. And in all systems after I did fsck on each of them, all the data inside the partition are gone (deleted, or removed into lost+found/ directory). So this breakage was the problem.

I want to solve this problem, however. And finally I think “how about changing the filesystem to btrfs?”. Yes, as you could see on UbuntuBuzz, all my tutorials recommend EXT4, because I myself only use EXT4 in all time. So this time I tried to change it to BTRFS. I installed Trisquel 8.0 Final Stable two days ago and yes! The problem seems gone. I can use the SDCard with Trisquel over BTRFS there without breakage, without fsck checking too, and without corrupting the partition! Then it is solved for now. This way I can continue my review to the new Trisquel and more. Ah, yes, I should say that installing with EXT4 into SDCard takes 30 minutes, while with BTRFS I found it takes 1 hours.

However, I don’t know if the same problem could happen again in next time. Walhamdulillah.

Internet Privacy For Newbie, Briefly

Bismillahirrahmanirrahim.

This is a short summary in protecting internet privacy that is easy to practice for any computer user.

One

Don’t use Google Search. Change your search engine to StartPage.com.

Two

Don’t use Google Chrome. Change your web browser to Mozilla Firefox, use privacy addons:

  • uBlock Origin: the best advertisement blocker.
  • HTTPS Everywhere: the encryptor of whole connections of each webpage you visit. With this, all connections are secure.
  • Privacy Badger: the antitracker, the purger of all online trackers, it secures your privacy by removing each website’s personal-info-collectors that do not respect your privacy.

Three

Remember one thing: anything sent to the internet cannot be erased, forever. Best practice: don’t post your complete address on the internet, the same goes for everything else, so:

  • don’t send your phone number to facebook or others
  • don’t send copy of your photos, National ID Card, Driving License, or Family Registry, to facebook or others

Warning, packagekitd and snapd Eat Bandwidth!

Bismillahirrahmanirrahim.

Now I know for sure why each distro I ran eats my bandwidth extremely a lot without my permission, that’s because of PackageKit’s packagekitd daemon doing automatic updates in stealth. Not only that, but also Snappy’s snapd daemon eats my bandwidth without my permission too. Those two packagekitd and snapd are serious problems for limitedly-bandwidth users! These happened on neon, my favorite KDE distro, and also Ubuntu, Kubuntu, even openSUSE, and even Fedora. Tonight I do some searching and I finally understand packagekitd action is a part of GNOME Software or KDE Discover automatic update. Continue reading

First Time Running GNOME Builder

Bismillahirrahmanirrahim.

  • sudo dnf install gettext-common-devel gettext-devel autoconf-archive gtk3-devel gcc-c++
  • Fedora 26
  • I encountered errors while building pre-build samples such as ‘AX_GENERATE_CHANGELOG: command not found’
  • GNOME Builder can download big amount of data (Flatpak library things) without my permission by default and I dislike this, I value my internet bandwidth more than this
  • I have experiences in Qt Creator previously (I like it so much), so GNOME Builder is a new thing for me
  • Clean interface, easy to understand, no excessive number of buttons, build buttons are straightforwardly placed on center (this is good)
  • Build output are placed in a way that is simple and understandable, easier to copy the messages to the internet

I really like the licenses selection on new project screen. This eases new programmers to get accustomed to free software development. Good job, GNOME Developers!
