January-August 2023

Translated from Simplified Chinese by AI.Read the original

More than half of 2023 has passed, so let me sum up these past six-plus months. Even though it's all just a mundane diary, at least it helps me recall and sort out what I've done, and keeps me from feeling like I've wasted my time (a bit of psychological comfort, I guess (/▽\)

Cover: a cloud I cropped out

January

I was mainly busy building my own anime media library; the related stuff is all in this repository. Basically, a Scheduler periodically pulls RSS updates of nyaa.si search results, dispatches tasks to a Fetcher, and the Fetcher downloads them and uploads to OneDrive via Rclone. I tweaked onedrive-vercel-index a bit as the frontend, added some reverse proxy stuff, and so far the whole project is running well.

In the end I realized I really don't have much time to watch any of it..

February

I mentioned before in my planted tank setup log that I put together my own filtration system using a non-powered canister and an external water pump. It was very cost-effective, but there was one drawback: leaks easily

After about half a year, the system started leaking and trapping air and air-locking. Leaks could be fixed, but I really couldn't figure out where the trapped air was coming from. In the end I couldn't avoid buying a ready-made filter canister. I chose a positive-pressure canister; no need to suck on the hose to bleed air, it starts with one button.

Filter media space is also much larger than before, and the water looks clearer (yay!)

Then school started. Because of the pandemic, last semester's final exams were pushed to the start of this semester. In the end I speedran them in two weeks with online course videos ( ̄ ω  ̄o)

March

I set up a 15cm*15cm*20cm unfiltered small tank in the dorm:

But because the water volume was too small to stay stable, it grew black brush algae, and I ended up giving it away at the end of the semester..

I threw together an online CD shelf, including some metadata, my reviews, and lossless ripped audio; the repo is on GitHub. The jewel cases were rendered and exported in Blender, and I stacked a bunch of effects before the jewel cases and CD covers looked somewhat harmonious.

Finally, to be lazy, I used it as the final project for the school's web frontend programming course (

Ripping and collecting metadata is also a hassle, so there are only a few CDs for now (;´д `)ゞ. I should gradually add more later.. probably

April

I was mainly busy with the school's C language engineering practice; I don't think I did much else.

May

Also because my first semester of freshman year was affected by COVID, the start of school and military training were postponed, so our military training was made up this semester.

To sum up: dead tired + got tanned. On the last day, during the presentation performance, I had a fever, tested positive on an antigen test, and got COVID. It took five days of misery before I improved.. My sense of smell took about a month to recover.

Sure enough, that previous article jinxed it, huh /_ \

June

Finals month, busy speedrunning (

But I also stole some time from the busyness; when I went home for vacation I recorded this planted tank log:

July

Summer vacation started (≧∀≦)ゞ

When I got home I found the planted tank was in bad shape, and on top of that the hardscape had loosened and branches had fallen off, so I decided to redo the tank.

alt Making a new scape

Learning from last time—complex layouts are hard to maintain—this time the layout is quite plain.

Also, because I really like the shimmering effect created by spotlights, I tried DIYing a spotlight for the planted tank.

alt A pretty crude shell, right

The LED chips are from the Luminus CXM-14 series, 5000 K color temperature, and I adjusted the constant-current driver board to 25 W.

I tried 3D printing a shell and made a soldering fume extractor fan; it looks pretty good (

August

I got a Tamron A030 and a second-generation FTZ mount adapter, and took them out to play → Gallery: 2023-8

I took over from the lab's frontend team lead Zongzi (I got it by rolling 〒 ▽ 〒), and then I was busy with the lab's recruitment work—writing training manuals, making assessment questions, and stuff like that. Ah, kind of a hassle (


That's about it for this post. I actually created the file for this record at the end of March and put it off for a very long time. The title I picked back then was still 春よ、来い, and now it's already the start of autumn (a little realization
