A great post about RCE vulnerability in MX Player. The funny part is the RCE was gained because of some Facebook SDK.

setCurrentScreen method in Firebase Analytics is now deprecated. You're free to track the screen_view event whenever you like.

Several great examples of what you can build using simple gradient in XML.

Google introduces a replacement for SharedPreferences - DataStore.
This thing can handle errors, knows how to work in a non-blocking way and even has transactions! Moreover, now you can store protobuf-serialized typed objects.
Looks very promising, I'm looking forward to a stable release.

A nice tutorial on how to build your very own daemon. I was surprised to learn that single fork() invokation is not enough.

An investigation post: how much memory do objects really hold on Android? Primary conclusion - Android heap dumps give us the real size of instances.
 
#art #memory #cpp

In Android 11 ART can update class layout on-the-fly. It can be used with features like Apply Changes in Android Studio. This thing is called Structural Class Redefinition and you'll find a bunch of interesting details in the post.

How to leak memory with two hands, PackageManager and some references?

After a long day of fighting RecyclerView and UI thread it’s always nice to just sit, relax, and learn how to build an async ViewHolder creator using Kotlin Channels.

#recycler #async #channel

Found an interesting idea in this post: using suspend modifier to mark all non-pure functions and to prevent us from invoking those functions from the pure ones. The idea becomes especially interesting with Redux-like approaches.

#kotlin #coroutine #fp

Working with timestamps and timezones is almost always a hassle. Moreover, SQLite doesn’t have a dedicated type to store such values. However, there are some built-in functions to simplify such tasks. In this post you’ll find a good example of using them in a real production app.

P.S. Here you’ll find a funny video about general problems with dates, time and timezones.

#sqlite #db #date

In this post you’ll learn how to apply coroutines for awaiting a layout pass completion or an animation end.

#ui #view #coroutine

If using multiple nested .copy calls on data classes is your case for whatever reason, take a look at this post, Arrow-kt will probably make your life a bit easier.

#arrowkt #fp #library

In this post you’ll find a nice explanation of how tail call optimization works. Surprise-surprise, the optmization also works fine with non-recursive functions.

#compiler #optimize #recursion

Draft JEP on Primitive Objects.
It’s something like an immutable class without identity. Copy of such an object is an exact copy of that original object. And there are plans on treating int, boolean, etc. as primitive objects. We’re waiting for you, List<int>!

#java #jep #primitive

Fun, fun, fun! There’s an issue in linuxmint/cinnamon-screensaver: some kids were fooling around with lockscreen, clicking and typing random stuff, then screensaver crashed, letting them pass into the system.

Why would anyone want to fix broken toilets or to stop using GNOME, if they can keep enjoying this sweet pain?

Contempt Culture
I wonder, are there similar attitudes in the world of MDs? Do oncologists despise otolaryngologists? Do otolaryngologists in turn disdain proctologists? Does the whole bunch of them disrespect therapists?
All right, then. Who will patch my butt up after the explosion that usually happens when I spend a day fighting Android SDK?

@dsvoronin has recently shared “The Tragedy of systemd” talk by Benno Rice (one of FreeBSD contributors). systemd is a controversial piece of tech. In his talk Benno tried to dig deeper into the history of systemd, what it is criticized for, and why it’s not all that bad.
The talk itself is great by the way. I’ll put some quotes into the discussions.
