After counting the rent (for the next 3 months) and common charge (for the next 1 year), the expense for June blows up again.

And I have to buy some electronics for the new house... The total expense might again be around 10K CNY...

Why saving money is so hard :(

Someone: Rolling update will provide more smaller step updates, so it's less likely breaking your setup by upgrading.

Me:

Heavy rain? The thunder is scaring the shit out of me. I want to sleep, but I can't. Because the sudden big bang sounds low and kept me frightened

Moderate rain but 39C?

Is it raining hot water?

Looks like either the seller gives the wrong dimensions or I measured wrong.

Anyway, this unit is wider than I thought. And all of my windows won't fit, so I set it up using the toilet.

Room temperature: 25C
Toilet temperature: 40C

Large: 30km
Normal: 20km
Mini: 15km

When I saw this number of citations, I know someone is serious.

The web ui is kind of weird for this: I saw the citations first, then the main content... And it's too much English for an Asian in a weekend, LOL

36C in door

It's so hot 🔥

The fan is blowing fire instead of wind...

Ordered a window unit. I can't live with 35C ALL DAY. Even during the night it's 33C.

Apparently, the window is not wide enough. But I have an idea. Who said a window unit must be installed in a window? I have a spare door that I am occasionally using. For the rest of the day and night, it's useless. Yes, I'm talking about the loo.

With such high temperatures, I'm forced to come up with something that can at least cool me down.

Found a Taiwan ebook store, managed to make a purchase. It mentioned PDF when purchase but it requires you to either use their web or their mobile app to read.

Then guess what? The JS code for web is raw js. I mean, when almost everyone is using something like typescript and framework, I would never expect something so simple like this would work.

Hijack the code for displaying the image and grab the content. So everytime I read a page, it gets downloaded to my computer.

I would say it's "fair use". In the worse case I can inject my own SSL cert into the system and grab the content anyway. Unless the image data is encrypted and need some js code to decrypt on the client side.

And with a quick poking around during the lunch break, now I can import amazon purchases without a physical Kindle.

And this book can be only purchased by the Japanese account. Luckily a Japanese account is much easier to maintain compared to a Taiwan account. There is traditional Chinese translation on Google Play, but you can only buy it if your account is in Taiwan, which is really hard to register.

Well, just found out you can't export everything from the Google Play book. For the English version, vol. 8, 9 and 12 are not available for export due to the publisher's settings.

And weird enough, this manga is not found on Zlibrary, Anna's Archive, thepiratebay and 1337x.

I love how the open source community works together to crack this DRM bullshit. I bought the book, you should give me the PDF. Not some DRM-protected ACSM shit.

yes, there is an English version on Google play!

Also found a satellite in the image.

By using the pixel merge feature provided by the hardware (instead of using software when pre-processing), the image quality is much better, aka less noise. Today I have no issues when blowing up the saturation slider, and this time there is no noise. Yesterday I couldn't move the saturation slider at all, since even a slight increase, it shows a bunch of noise and makes the image look terrible.

With 4 pixels merged into 1, I got 3.9 μm per pixel, which allows me to bump up the exposure time to 20s. However, I also tested the ISO settings, which show a better result in ISO 1600, compared to ISO 800. However, thanks to the light pollution, 15S with ISO 800 is on the edge of overexposure. So I didn't stick with higher ISO.

However, yesterday night was cloudy, and I'm too lazy to pick the picture one by one. So I dump them all into the software, and thanks to the cloud, now stars are not pinpoints anymore.

Why will the author think HTML and JS are magic? I thought Haskell and Lisp were.

This is a good one, considering I didn't aim for anything interesting but just a random area of night sky where no trees or buildings are blocking the view. I mean, it's pretty random.

You can actually tell the Lyra (Fig 2) and the Sagitta (Fig 3).

And all of this, is shoot on an action camera, costs only 350 USD. Wow, I'm deeply amazed.

BTW I'm using Sequator for stacking, looks like it can handle the lens aberration pretty good.

Tried to stacking some night sky photos...

It looks like DeepSkyStacker is not capable of handling image produced by non-professional gear, I mean the action camera.

I spend a good amount of time calculating the NPF rule for my Insta360 Ace Pro, and trying to figure out how to do the aberration correction. And the result is... I would say not very ideal, when following the tutorial from here: https://www.youtube.com/watch?v=iuMZG-SyDCU

Maybe I should write my own software to do the aligning and stacking?

Also I have a hard time distinguishing if a point is a star or just dust on my monitor...

Instead of changing the sound for the alarm, I would prefer a way to change the way to dismiss alarm. Since for now, I can dismiss alarm without actually waking up. That's why today, I was waking up late.
