I’ve had the Fydetab Duo for over a month, and I’m still trying to find ways to make the most use of this device. At the very least, I’d like to write some blogs during my downtime with it. Hence the following exploration.

Bioinformatics is an interdisciplinary field, and the toolkit or technology stack used in bioinformatics is also quite “interdisciplinary”. The level of fragmentation is, in my opinion, absolutely not less than that of Linux distributions… This also brings us a common challenge: the deployment of bioinformatics analysis environments.

Recently, out of… well, let’s say a bit of dissatisfaction, I sold my previously purchased Lenovo Chrome Duet2, but then I bought a Pixelbook 2017… Now that I have this device, I still want to tinker with it for a while, trying to find a way to use this Pixelbook 2017 as a replacement for my work computer for general office tasks. In the process of practising, the main issue wasn’t resolved, but I did come up with a few practical by-products… writing Hexo blogs using Codespace is one of them.

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.
