On god, tho. It kinda sucks to copy this.

I kinda wanna make a copy button now for the code blocks.

## Pull boot.img

If you want it from the A partition, use this:

```bash
spd_dump exec_addr 0x65015f48 fdl fdl1-dl.bin 0x65000800 fdl fdl2-dl.bin 0x9efffe00 exec read_part boot_a 0 64m boot.img reset
```

If you want it from the B partition, use this:

```bash
spd_dump exec_addr 0x65015f48 fdl fdl1-dl.bin 0x65000800 fdl fdl2-dl.bin 0x9efffe00 exec read_part boot_b 0 64m boot.img reset
```

Yes, I know. It's literally one character difference.

## Flashing GSI

Download the GSI, go into fastboot mode, and run this:

```bash
fastboot delete-logical-partition product_a
fastboot delete-logical-partition product_b
fastboot delete-logical-partition system_ext_a
fastboot delete-logical-partition system_ext_b
fastboot flash system gsi.img
fastboot flash userdata userdata.img
```

## Fixing brightness on GSI

> If you're on Kitsune Mask debug build, I suggest taking a quick read of [this post](/shorts/kitsumask-su) before continuing.

Go into Termux and type this command:

```bash
su -c echo 500 > /sys/class/backlight/sprd_backlight/brightness
```

You can change 500 to the range between 1-4095.

## Kitsune Mask latest debug build workaround for Termux

In general, latest debug builds of Kitsune Mask changed the mounting
location of `su` binary from `/system/bin` to `/apex/com.android.runtime/bin`
to reduce bind mount. This is a good thing, but it breaks Termux's hardcoded
`su` path.

This is not a permanent solution and is merely a dumb way of some sorts
to make commands at least work in Termux.

```bash
alias su="/debug_ramdisk/su"
alias sudo="/debug_ramdisk/su -c"
```

Yes, it's that dumb. But it works.

## The legendary PSD poem

Created for documentation and archive reasons. Apparently this guy doesn't like PSD:

```
// At this point, I'd like to take a moment to speak to you about the Adobe PSD format.
// PSD is not a good format. PSD is not even a bad format. Calling it such would be an
// insult to other bad formats, such as PCX or JPEG. No, PSD is an abysmal format. Having
// worked on this code for several weeks now, my hate for PSD has grown to a raging fire
// that burns with the fierce passion of a million suns.
// If there are two different ways of doing something, PSD will do both, in different
// places. It will then make up three more ways no sane human would think of, and do those
// too. PSD makes inconsistency an art form. Why, for instance, did it suddenly decide
// that *these* particular chunks should be aligned to four bytes, and that this alignement
// should *not* be included in the size? Other chunks in other places are either unaligned,
// or aligned with the alignment included in the size. Here, though, it is not included.
// Either one of these three behaviours would be fine. A sane format would pick one. PSD,
// of course, uses all three, and more.
// Trying to get data out of a PSD file is like trying to find something in the attic of
// your eccentric old uncle who died in a freak freshwater shark attack on his 58th
// birthday. That last detail may not be important for the purposes of the simile, but
// at this point I am spending a lot of time imagining amusing fates for the people
// responsible for this Rube Goldberg of a file format.
// Earlier, I tried to get a hold of the latest specs for the PSD file format. To do this,
// I had to apply to them for permission to apply to them to have them consider sending
// me this sacred tome. This would have involved faxing them a copy of some document or
// other, probably signed in blood. I can only imagine that they make this process so
// difficult because they are intensely ashamed of having created this abomination. I
// was naturally not gullible enough to go through with this procedure, but if I had done
// so, I would have printed out every single page of the spec, and set them all on fire.
// Were it within my power, I would gather every single copy of those specs, and launch
// them on a spaceship directly into the sun.
//
// PSD is not my favourite file format.
```

## Uhh so

A bit of reminders that:

- Need to somehow reduce the bundle size of the app
- A shortlink generator might be useful
- Commenting system and an issue tracker is also helpful
- What kind of database should I use?
- Analytics is also important
- I kinda wanna make it PWA
- Migrate some of the old posts from the old blog
