Jun's Blog

At the end of the year 2022, I would share my reflections on the year 2022 with this article. Previously I wrote the 2020 version of the article.

In recent years, I learned how to work with big open-source projects. It was fun and meaningful. Because open-source projects survive beyond one organization. And it gives opportunities to work with people beyond one organization as collective knowledge. When working in one organization or team, knowledge is challenged.

My interest and passion are in the process of 1. Open Software to 2. Open Hardware, 3. Open Bio, and 4. Open Aging Bio.

Filling human's basic needs

To have the motivation to fill human's advanced needs such as self-achievement, it's important to fill human's basic needs such as safety, and comfortability in life.

Studying diet and aging biology, I have improved my diet style. It's fun to see how my body, maybe microbiome and importantly my feeling changed by changing the food I eat. I live with a little sugar including something producing sugar such as carbs. I am comfortable with a little food, and intermittent fasting.

I finally migrated my main PC environment from Mac on MacBook Air to Fedora Linux on Framework Laptop. This makes my daily life fun and gives me lots of fun learning opportunities. Fedora Project and Framework have a thriving community, and staying in the community is a great learning system.

I found and started a new habit about how to spend time on info-tech, bio-tech, and learning the Czech language every week. This was a big change for me. And I should start it earlier. It gives me great happiness.

Living in a place that I found the best in Prague makes me happy. And the place is relatively safe. So, I don't need to pay extra attention to safety. It's important for my energy consumption. And it's accessible for healthy foods.

Open Software

I have been fortunate to work on the Fedora project and the Ruby project and other open-source software projects and to see how the projects work. An open-source project RPM Python Installer I created is growing slowly.

Open Hardware

In the context of open hardware, I spend time on Framework Laptop and Moonlander.

Framework Laptop

I have stayed in the Framework community. I have updated Framework's Wikipedia page. I felt that Framework and Framework Laptop are the best to advocate open hardware. The company surprises me constantly with what they do. We held a Fedora x Framework Talk event in Fedora Nest 2022. I assisted it as a host. As a reference, here is the event info page. The talk was since 3 years after my previous talk about QEMU on the Fedora project.

Moonlander

I also learned how it's fun to tinkering the hardware and customize the keyboard layout on the firmware level on the Moonlander. My latest Moonlander keyboard layout is 34 keys. And I see it's quite comfortable after practicing it.

Biology

In the summer of 2022, I tried FreeStyle Libre and observed what my blood sugar level trends look like by some foods. I am not diabetic. I used the device for my interest.

In September 2022, I helped a workshop (GitHub) for biology and genome sequencing in academia. and presented the demo at ECCB (European Conference on Computing Biology) 2022. It was great that I learned some new things, and I had an opportunity to see what the work in academia looks like. I saw there is a challenge or limitation of the incentivized system in academia for the greater good. The experience also made me study essential genomics, and I am doing it. The book Essential Genetics and Genomics that I am using to study genomics is great.

In December 2022, I submitted Nebula Genomics's WGS DNA test. I am waiting for the result now. Maybe I need to find a good SNPs-driven healthy advisor after I get the result.

Aging Biology

This year I was inspired by the information below about aging biology.

Books
- The Switch - James W. Clement
- Ageless - Andrew Sttele: I am reading it now.
Youtube channel
- The Sheekey Science Show
Paper
- The Hallmarks of Aging

Others

Except for biology, the book I was inspired by in 2022 is Think Again - Adam Grant. I learned that I have biases, and how important to think again.

I referred to the [1].

Install Slack

First, you need to install Flatpak if you don't have it.

$ sudo dnf install flatpak

Install the flathub repo file.

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

Reboot at once in this timing.

$ sudo reboot

Install Slack.

$ flatpak install flathub com.slack.Slack -y

Run Slack

In my environment where running i3 by running the startx, I saw the error below.

$ flatpak run com.slack.Slack
[2 zypak-helper] Failed to connect to session bus: [org.freedesktop.DBus.Error.NotSupported] Using X11 for dbus-daemon autolaunch was disabled at compile time, set your DBUS_SESSION_BUS_ADDRESS instead
[2 zypak-helper] src/helper/main.cc:40(DetermineZygoteStrategy): Assertion failed: bus

I added the lines below, seeing the [2].

diff --git a/home/.xinitrc b/home/.xinitrc

+eval "$(dbus-launch --sh-syntax --exit-with-session)"
+
 exec i3

And it worked after running the startx again.

$ flatpak run com.slack.Slack

Here is the detail of the command above.

$ rpm -qf /bin/dbus-launch
dbus-x11-1.14.4-1.fc36.x86_64

$ dbus-launch --sh-syntax --exit-with-session
DBUS_SESSION_BUS_ADDRESS='unix:path=/tmp/dbus-rqcQtmDHcj,guid=776599334e0d304f27523f2d63868934';
export DBUS_SESSION_BUS_ADDRESS;
DBUS_SESSION_BUS_PID=8326;
DBUS_SESSION_BUS_WINDOWID=31457281;

I added the alias below.

.bashrc

+if flatpak info com.slack.Slack > /dev/null 2>&1; then
+    alias slack='flatpak run com.slack.Slack'
