Well AI can't understand or write good BLE code but it is good in wiring up UI options over them, in 3 different places. 🤗🤗🤗

Just listened to adbackstage.libsyn.com/android-deve.... Hate it.
This really is as terrible as it sounds.
Not even addressing the orange elephant in the room (bad government actors!), or that anonymity is often crucial for personal safety.
This feature can, and definitely will, be abused. 1/2

Also the remote MCP server support is very cool e.g. accessing a Figma design and converting it into Compose code

Casey Muratori pretty much sums up how I feel about LLMs for coding:
"The AI will always be useless for me. I physically can't get what I want from programming when AI is involved, because what it is doing is robbing me of the experience that I wanted to have and the knowledge that I wanted to get"

What would be the way to extract rgb and alpha part out of a video via ffmpeg?
I am trying to implemented the outlined here in this post only using ffmpeg instead of adobe after effects.
Specifically the input format of the video must be

What RenderNode really is 🧶
(thanks @romainguy.dev 🤩)
They are a list of drawing commands with some other properties like transforms (e.g: translation). These commands can be used to issue GPU commands by the internal renderer. They are not GPU commands on their own.

Where does one start with improving Android app performance? Should I start with writing benchmarks to establish a baseline? Should I enable StrictMode and LeakCanary first? How can I implement metrics in production?
Are there any good guides for beginners you'd recommend?

In a register a boolean is already an int. So the code I showed just disappears completely. This means I can do for instance (myBool.toInt() shl 6) - 1 to create a mask without using a branch. Sometimes an if will turn into a branchless condition but not always.

PSA: if you write v.pow(2f) (also .pow(3f)) on Android, please write v * v instead. pow() is a (relatively) expensive function call that won't get optimized away (yet). On a Pixel 6, pow(2f) is 5x slower than a multiplication. For long expressions, use inline fun square(v: Float) = v * v

I love Kotlin but please don't abuse its features. I regularly see code like in the first function when you can instead write a simple if statement: it's shorter, easier to read, and doesn't allocate an object!
Thankfully both functions compile to the same assembly when R8 is turned on.
