Since I started playing with the ancient version of Linux Deepin in my junior year (2011), it’s been 14 years now. During this long period, I’ve used Debian/RedHat/Arch-based distros, but except for accidentally deleting my graduation thesis in my final year of grad school, I’ve never encountered any malware or viruses on Linux distributions.

However last week, our company server… actually got infected…

Compile the OpenFyde Image for Fydetab Duo by synthesizing official instructions and forum articles, aiming to compile the latest R120 version image. The goal is to compile the latest R120 version image.

At one point, the biggest obstacle to my daily use of Linux distributions was the lack of QQ. Back then, I was a third-year student and QQ was an essential software for both learning and life. Although smartphones had already come into being, transferring files between phones and Linux computers was quite inconvenient at the time, and there wasn’t even a WPS Linux version… So, I eventually switched back to Windows.

I have always been interested in the status of domestic Linux systems (although I haven’t used any long-term except for an ancient version of Linux Deepin), so when Flint OS was still called FydeOS, I paid attention to this Chromium OS-based special edition. This also led me to understand why Chrome OS, which has a mysterious high share overseas in the past, is popular.

Recently, while organizing our materials for using graph databases, I thought of a problem. Actually, from a performance perspective, graph databases may not necessarily achieve better performance. For us, the significance lies in simplifying the requirements for database design.

Today, after upgrading Manjaro, the most basic ssh login suddenly had issues, and the prompts were as follows:

1
2
3
4

Unable to negotiate with UNKNOWN port 65535: no matching host key type found. Their offer: ssh-rsa,ssh-dss
lost connection

sign_and_send_pubkey: no mutual signature supported

Upon investigation, I found out…well, OpenSSH deems the ssh-rsa encryption method insecure and has directly disabled this key type for logins by default starting from 8.8…

When using a Linux system, it’s often necessary to set up things that start automatically at boot. For distributions that use systemd, writing your own service files and enabling them is a great choice.

As long as you use multiple devices for work, you will inevitably encounter the problem of mutual synchronization between different devices. Now that it’s not the era when cloud services just started to rise and were cheap and generous, there probably isn’t a reliable and user-friendly service provider that won’t suddenly run away or change its terms of service. So, we still have to rely on ourselves to set up our own…

Recently, my work requires me to understand some common machine learning methods. I’ll just write a post about it…
