Broadcom is shit. Period.

Today I spend some time in the video recording using my Nikon Z50II, I asked Google's Gemini 2.5 Pro, and the conclusion feels pretty solid.

The conclusion is that:

1. Recording in 4k30p will use the full CMOS data and super sampled to 4K
2. Recording in 4k60p results into a 1.5x crop in addition to the APS-C sensor, which results in a 1:1 mapping from the CMOS pixel to the video frame pixel. Due to the bayer filter, each pixel on the CMOS will only record one channel of RGB colors, and the video will look soft compared to 4k30p.
3. Recording in FHD (1080) will also use super sampling, even with the Hi-Res Zoom enabled. But the overall benefits are not worth downsizing from 4k to 1080.

In my case, I think details are pretty important. Today I took a video from about 150 to 200 meters away for a little grebe (Tachybaptus ruficollis). I tried both 4k30p and 4k60p, none of them can capture the details. I can distinguish it because it's a blob of black with some red at its neck. But in 4k60p, without super sampling, everything, including the little egret (Egretta garzetta) at 115 meters away, is soft and lacking details. In contrast, 4k30p can give a better viewing experience since everything is sharper (but smaller).

I'd prefer 4k30p, even with birds. If 30 fps is not enough, then I probably need a Z8.

@trinsec From 3am to 1pm? But yes, still 10 hours. I didn't wake up in the middle, and it's 1pm as soon as I wake up and open my eyes.

Me at 2am last night: Frieren is so good, it's worth staying up late to finish it

Today, me woke up at 1pm, exhausted: No, it's not.

I also made a comparison with Sony PCM-A10, which is my original plan for recording audio: https://www.youtube.com/watch?v=MBPM3fwlfdY

The PCM A10 doesn't have too much directivity, and the audio sounds flat. I would say MKE600 worth the money

Bought a sennheiser MKE600 microphone, for its price, I'm planning:

1. record video with it so I can capture the birds singing.
2. use it on my work machine so I can join meetings on my nuc.

For the second purpose, I need a P48 power supply. I searched aliexpress, but all of them require AC18V input, while P48 output DC48V. Not sure why.

> I though I'm using virtiofs, but it's actually 9p.

Don't ask how long it takes me to figure that out. I spent half of my day to search why file mmap failed on virtiofs, all result suggest it shouldn't be.

Switched from Tixati to qBittorrent for BTN support since my nas has been leeched by a list of datacenter IPs.

Then I noticed that qbittorrent failed to write any file. After some digging, it turns out the C lib failed to do `file_mmap`. I'm using unraid and it offers both 9p and virtiofs to mount shares to vm. I though I'm using virtiofs, but it's actually 9p. The 9p mode failed to support mmap and the read performance is slow. With my ZFS setup, it can only read 60MB/s.

After switching to virtiofs, the read performance is back to normal, reaching about 700MB/s and mmap is working out of box.

I think unraid should really make the virtiofs as the first option, instead of 9p.

Looks like 48GB RAM is not enough for 60+ chrome tabs, 18 docker services, and 6 electron based applications.

No... Not really.

Although I hate Adobe, I still rely on them to process my photos, especially Lightroom Classic, I haven't seen any good alternatives yet.

For Photoshop, I tried alternatives like affinity photo, which is a good commercial product, but I'm not really into it. Not mention gimp and darktable.

I love sleeping

Wow, sleeping is magical. No matter how sad I am, a good sleep always makes me feel better.

I had a conflict with my parents, and I feel down. I was typing a bunch of words here, maybe not sharing with anyone, just want to spill them out and hopefully make me feel better. Then, suddenly, I thought, screw that, I lost the mood of typing and explaining that thing. I don't want to talk to anyone because I feel tired, down, a bit of anger, and eventually, frustration.

Finally, at this time, I realized that I became a pathetic man. The pathetic man who struggles but doesn't have the motivation to solve the issue or at least make himself feel better. The pathetic man that I hate to become. The pathetic man who is always escaping, running away. Heck, I'm writing this in English because it's not my native language. It gives me a third-person-perspective-ish isolation, so it feels like I'm describing something that happens on someone I really know instead of myself.

With my pathological overthinking, I was never expecting life to become hard in this way.

For the conflict itself, shortly speaking, I cherish the novels I bought from Taiwan, and I have been trying to keep them in the best condition I can. But for my parents, they are just a pile of paper wasting space. I clearly told them to put the books back to their original place after the repairs were completed, but my parents decided to take them out and put them in the outdoor utility room. Based on past experiences, everything there will be conquered by nature, mostly oxygen and moisture. Those will be destroyed, and I can do nothing. Now? I still treasure those books, but now I feel like I'm able to lose everything, including my life, at any time. I simply stop caring about anything so they won't hurt me. I know the reason behind this, but I have no way to fix it.

I don't want to admit, and my brain says everything is totally fine, but I can sense there are serious issues with my mental health. They might not be serious enough to blow me up, but something could go wrong in the long term with the current pace. However, I don't care to do something about it. Sounds familiar? I hope that don't-care mood won't expand to other things.

Anyway, it's 2am, enough gibberish. Good night, my friends.
