Is Facebook an anti-democracy tool?

Read The Autocracy App, published in The New York Review of Books, and draw your own conclusions. It’s a long, but well worth, text about the impacts of Facebook on our societies and the apparent inclination it has for favoring dictatorships and autocracies.

It gave me the chills…

Things to do after installing Fedora


Third-party repositories will be enabled and it was only tested on Fedora 28. This could have an impact on your system ranging from none to destroying all cat videos on the internet. You have been warned.

Disable annoying AMD iommu warnings on boot

Only for some AMD CPUs, like mine, an AMD A9-9420

Edit the /etc/default/grub file and append the following to the GRUB_CMDLINE_LINUX line:

iommu=soft amd_iommu=off

Full example:

GRUB_CMDLINE_LINUX="resume=/dev/mapper/fedora_localhost--live-swap rhgb quiet iommu=soft amd_iommu=off"

Finally, generate the new GRUB configuration to take effect on your next reboot and any kernel update thereafter:

sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

Enable Negativo17 multimedia repository

Negativo17 has more repositories. You can use them to install Steam, Spotify and more apps. Check their website for more info.

This repositories contains codecs and multimedia software (HandBrake and Blender with CUDA support, for example). A must have.

sudo dnf config-manager --add-repo= -y

Enable third-party repositories “supported” by Fedora

Refer to the Fedora Wiki for more info.

Enable Visual Studio Code repository

sudo rpm --import

sudo sh -c 'echo -e "[code]\nname=Visual Studio Code\nbaseurl=\nenabled=1\ngpgcheck=1\ngpgkey=" > /etc/yum.repos.d/vscode.repo'

Install all codecs

sudo dnf install gstreamer1-{plugin-crystalhd,ffmpeg,plugins-{good,ugly,bad{,-free,-nonfree,-freeworld,-extras}{,-extras}}} libmpg123 lame-libs --setopt=strict=0 -y

Apps to install with DNF

Needs Negativo17 repos enabled (not only the multimedia one)
sudo dnf install -y snapd gnome-tweaks dconf-editor mpv gnome-mpv vlc dnfdragora gimp gimpfx-foundry gimp-luminosity-masks gimp-fourier-plugin gimp-focusblur-plugin gmic gmic-gimp inkscape flameshot vokoscreen kodi jpegoptim optipng micro steam qemu-system-x86 youtube-dl mplayer qbittorrent spotify steam pycharm-community pycharm-community-plugins code

Apps to install with Flatpak

First, enable flathub repo for Flatpak
sudo flatpak remote-add --if-not-exists flathub
Then install the apps
sudo flatpak install flathub io.github.wereturtle.ghostwrhiter com.github.marktext.marktext io.github.Pithos

Blacklist radeon driver

For some reason, the system completely freezes randomly if I don’t blacklist the radeon driver. Maybe it interferes with the amdgpu driver that is needed by my GPUs or maybe it’s something related to Prime, but this are just guesses.

echo 'blacklist radeon' | sudo tee --append /etc/modules.d/blacklist.conf

(Optional) Install minimal Plasma Desktop Environment

sudo dnf install @critical-path-kde plasma-workspace plasma-workspace-wayland kde-settings kde-settings-plasma kde-settings-pulseaudio plasma-nm plasma-nm-openvpn plasma-nm-ssh plasma-applet-redshift-control plasma-browser-integration kde-l10n-pt kde-gtk-config dolphin konsole gwenview plasma-workspace kate-plugins kate konsole5 kde-gtk-config ksysguard -y

Thanks, /u/jflory7, for the tips to improve this “guide”.

IQ tests are flawed?

Popular Science published an article on May 2018, that I only just read, about flaws in the concept of IQ and IQ tests. The text actually presents some good arguments. From the article:

Too many of us use the terms “IQ” and “intelligence” as if they’re interchangeable. They’re not. An IQ score isn’t a magical signifier of smarts; it merely quantifies your ability to take a particular kind of test. Wealthy, white Westerners tend to perform among the best on these exams, but that doesn’t mean they’re smarter than the rest of the world. Research increasingly indicates that the advantages that group enjoys—like better education and healthcare—set them up for success on such evaluations. And it doesn’t hurt that the most expensive education is generally geared toward improving one’s ability to fill in the proper bubbles. Access to money, school, and medicine can all change apparent acumen—but IQ ignores inherent intellect.

Sara Chodosh – Popular Science

Well, I guess my average of 130 IQ points (don’t know the scale used, however) now feel sad.

The “joys” of IBS

About 7 or 8 years ago, I was diagnosed with IBS. If you don’t know what it is, it stands for Irritable Bowel Syndrome and it’s a functional gastrointestinal disorder that’s estimated to affect 10% to 15% of the world population.

In most cases, as far as I know, a simple change in diet allows one to keep the symptoms mostly at bay and have a normal life. For some unlucky few, it will fuck up their life in ways they can’t imagine. And I don’t mean quitting coffee like I had to do (I had an gigantic headache during the first two weeks after quitting) or develop a lactose intolerance (like I also did) that forced me to exclude even more food from my diet. I mean things like wanting to go out with your girlfriend and/or friends but choosing to stay at home because your bowl feels a little strange and that’s always a sign that acute pain or some other symptom is just around the corner. Or feeling outright tired for no reason other than being in pain.

The negative effect is not just in your social life. Your work will be affected and no employer wants to deal with that. If you’re unlucky and have severe and frequent symptoms, you’ll probably not be able to keep a job for too long, even if you work harder than anyone else.

But you know what’s the worst part? Those closest to you patronizing or antagonizing your pain. I’ve lost count of the times someone told me to take a pill when I’m in acute pain (most of the times, only strong painkillers work and sadly not that much) or to go to the bathroom. I wish it was that easy…

This causes stress. A lot of stress. And stress in one trigger for IBS. So, sometimes, the people closest to you make you and your life worst. If you happen to have someone like this in your life, cut him/her off. Your bowel and overall health will thank you.

It doesn’t help that most doctors either don’t know a thing about IBS or only know outdated and usually incorrect information. I’m including here so-called gastroenterologists . I’ve met a few that know way less than I do about this.

If all of this seems exacerbated to you, let me tell you: I’m with a sick leave, tried a ‘but load’ of different medications, fasting for two days so I could give my lower intestine some rest, did several exams (that, like always, show nothing wrong, a normal thing with IBS), and it’s 06:41am (at the time of writing) and I’m awake again, with pain, trying to write this for the last three or four hours in an attempt to distract me a bit from the cramps.

Yay for the shitshow that is IBS.
