Today's lesson: never use move to move data. Use copy + delete.

Today I was moving the data out and in zfs pool since I initially get the parameter wrong, and I want to clean up the mess.

Suddenly, the light goes out. The power is gone. My NAS has a UPS and triggers the shutdown at 70% remaining capacity, but somehow the moving process prevents the system from shutting down, and eventually the battery died, and my NAS lost power.

The good news? ZFS is recovering, by rolling back something, I don't know.

The bad news? The source is deleted but zfs rolling back some pointer discarded the written data. Now I lost the file.

Luckly I have backup covering my ass.

I like this quote.

While Nikon doesn't do a great job on focusing (figure 1), it does a great job on VR (vibration reduction, or Image Stabilisation for Cannon and Optical SteadyShot for Sony).

Picture 2 is shot under a low-light condition, which my camera model is not expensive enough to handle it, so I limit the ISO to 6400. If the picture is still underexposed, then I just give up since that means my camera can't capture this scene.

However, with limited light and the shutter speed well below the safety range (usually the safe shutter speed is 1 divided by focal length, in this case, 600mm should use at most 1/600s, which is 1/640s in my camera), it managed to capture one photo that is in focus, and sharp enough to let DXO Photolab to recognize all the details and enhance them.

Amazing. (of course, DXO is also an amazing software)

got my Google takeout file. Looks not bad, at least all Metadata is here. So now I hate Microsoft more.

Now I equally hate Google and Microsoft.

It has been 4 hours and google takeout is still not ready yet. Microsoft onedrive is hard to download in bulk. Right now I'm using cyberduck to download folders in 10 threads. Hopefully they won't rate limit me.

Deployed immich on my NAS, now trying to download all photo backups from Google and Microsoft.

It's easy to upload your stuff onto cloud, but it's super hard to get them back.

Google requires you to use takeout to bulk get your data in their own format. Microsoft doesn't give you a change, it streams files into a zip via HTTP, it's a very fragile connection....

As steam said, I play game on Linux. I like suffer. LOL

I sincerely don't understand why people will include emoji in their writing.

This will be a new reason for me to not like python.

Wait, what?

Ministry of the Interior of France, telling me the BreachForums is reopening?

Must be some email trick. Can't verify on my phone but maybe France government doesn't enforce their dkim settings. Or they really get hacked?

Compared my recordings with the soggfy‘ogg. Other than the silence is a bit off (I still didn't figure out a perfect way to decide when the new song starts), the rest of the content is more or less identical (in terms of hearing)

Got something for the Spotify recorder.

Instead of connecting java to dbus, which has 1 or 2 seconds of latency, playerctl provides a perfect way for recording when Spotify switched to the next track.

Now I'm recording a play list with w64 (wav but support more than 4GB), then try to slice them into individual wav files. Still having trouble on deciding the start of each track, since dbus is not really real time, I saw 300 to 500ms latency (from Spotify switch track to the script record timestamp).

I think we should have a law to enforce every song to have a 100ms silence at the end. Otherwise it's a headache for me to decide how to cut the spotify recordings. LOL

Spotify finally got the lossless option.

Now it's a good timing to figure out how to permanently secure my music collection.

Ladies and gentlemen, I hereby announce, this is my new co-worker.

Trying to find a HD portrait for Father Godwin, but no luck. So I tried Gemini 3 pro. God that works so great.

Remind me years ago when I first tried waifu2x.
