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.

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.

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>!

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.

@istima shared a great video: Quake III developers had to perform lots of 1 / sqrt(x) calculations. But it worked too slow. So, they’ve come up with an algorithm, that produces a good enough approximation, but works much faster. Enjoy!

Check out this talk by Yegor Bugayenko. It’s about the basics of EOLANG in it’s current state. It looks scary, it looks funny, watching it was interesting, try for yourself.

A long post on XDA with rumors and speculation about Android 12. Material NEXT? Custom themes support out-of-the-box? Scrolling screenshots? OS UI mockups look kinda nice by the way.

A very practical page of Elm guides: Types as Sets. By using well-tailored types we can protect ourselves from different kinds of invalid states in our programs. So why not just use this approach?

Two for the price of one this time. Bruce Eckel (you’ll most probably know this guy, at least for the “Thinking in Java” book) in his post has criticized Gradle a bit, and Cédric Champeau (was building Groovy, is building Gradle) has tried to challenge Bruce’s points.

Here we go again: @Deprecated annotation has become deprecated itself because of a tiny bug in documentation processing.

Big boys want discuss big toys! Big boys want build big toys! Big boys start Mobile Native Foundation. Very nice!

By the way, check out the discussions page, it’s somewhat interesting to read.

Check out this new library from Square - Curtains. It’s a bunch of Window-related APIs to make some very unpleasant things a little bit easier.

Looks like an important thing: the 1st release of Projector is out. This tool allows us to stream IDE from a powerful server to a weak client.

The title of this post speaks for itself: “What every developer should know about TCP”. Nothing mind-blowing, just a nice reminder.
