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.

In daily work, there are always times when you need to create a presentation document to show project progress or results. However, creating a PPT is quite time-consuming (my obsessive-compulsive disorder always makes me adjust the font and position). I’ve never used any of the fancy elements and features of PPTs, so I found Marp to save some effort.

It was a night when I felt overwhelmed by reading papers (March 29, 2022). As I browsed through the messy directory tree in Zotero… it suddenly occurred to me how many papers I had read over the past few years? Exporting from emails… I was shocked… 561 entries, 419 PDFs downloaded… really… If I had gone straight for a PhD, I probably wouldn’t have read so many papers.

Although DingTalk is somewhat of a tool that exploits people, it’s still necessary for work. It’s already better to have one less annoyance choice (speaking of which, Tencent). After all, being exploited is bad enough, but being both exploited and annoyed… being able to eliminate one annoyance is already an improvement.

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…

I’ve been using my Nuts Pro for over three years, and everything is slow, and the storage is always running out. It’s time to make a final effort… Desperate times call for desperate measures, so I’m going to try flashing it. If it works well, I can keep using it for another year and a half. If not, I’ll have to buy a new one with my end-of-year bonus.
