Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Popular XMPP App "Conversations" Removed from PlayStore by Google
Relevant copypasta:
Fellow humans, there are alternatives to Google and Apple! Your neck need not be under anyone's boot! You don't even need to give up any functionality:
Data service:
The simplest thing is to buy a prepaid SIM and top it off with cash. The lovely people over at /r/nocontract maintain a big spreadsheet so you can filter by various properties of the available contracts.
Another way to go is to pay for a postpaid plan with a virtual credit card (VCC) like at privacy.com. It won't be linked to your name at the telco, but of course privacy.com knows who you are. There is also Abine Blur, and some others.
Yet a third way to go, which is nascent, is buy an eSIM with crypto. You can also buy prepaid VCCs with crypto.
An interesting new choice is PGPP https://invisv.com/pgpp/ who rotate your IMSI and do some other cool stuff. It works by e-sims.
All these methods make you /pseudo/nymous, but obviously you're still identifiable by subscriber number and possibly IMEI, to put aside correlational things like your traffic profile. You can help this problem by routing everything through a VPN. Then you're pseudonymous but the cell carrier knows nothing about you other than that you use a VPN. Pay for the VPN with crypto. Of course now the VPN provider knows your traffic, but you're much more anonymous to them than you are to a telco. You make your choices. Defense in depth. Etc.
OS:
GrapheneOS: https://grapheneos.org/ Very much like Calyx, but extra-hardened and with no MicroG. No involvement with Google at all by default. You can make a secondary profile in which you install Google Play Services to set up an environment where you can run unprivileged Play services + whatever crapware you need that requires them. Unprivileged here means it's like any other app: if you don't give it access to your location, it won't know where you are. If you end the profile session when you leave, Play Services stops running and stops talking to Google.
CalyxOS: https://calyxos.org/ Privacy-respecting Android distribution that replaces Google spyware with MicroG, so you can have your cake and eat it too. Most everything will work as you're used to, but it does still talk to Google to make that happen.
LineageOS: https://lineageos.org/ The successor to CyanogenMod, will work with many different phones. More privacy and control than stock Android.
There are also many others: Sailfish, Replicant, e
Hardware:
CalyxOS and GrapheneOS run best on Pixels. The path of least resistance is to get one of these phones and run GrapheneOS with Google Services installed in one profile or other.
You could also buy a Librem 5 https://puri.sm/products/librem-5/ If privacy and security and hacking are really important to you.
Or a pinephone: https://www.pine64.org/pinephone/
Neither work very well by regular standards, but they're cool :-)

LineageOS is currently installed on 1.5M Android devices
It might be worth to switch to GrapheneOS if you have Pixel phones: https://grapheneos.org/
It is a more serious project than LineageOS in the sense that they take security very seriously and they take their development more professionally too. There are no disadvantages to using GrapheneOS compared to LineageOS.
You can see a comparison here: https://eylenburg.github.io/android_comparison.htm

Recommendations for an Android repair shop?
If it still powers up but just won't boot you could try installing https://grapheneos.org/.

Iphone Vs Android
On 4thgen Pixels and up you can install GrapheneOS which is a security and privacy focused Android build. It does not come with any Google services pre-installed but you can put them on. https://grapheneos.org/

Are you happy
yes... will also de-google it cuz we can install GrapheneOS and also close the bootloader

Replacing musl's malloc with mimalloc: any ideas?
mimalloc: mimalloc is an open source implementation of malloc, currently the best performing allocator.

Reptar
Some compiler writers thought that was the case, if [0] is related to OP. I don't have a "modern" (after 6th gen) Intel CPU to test it on, but note that most programs are compiled for a relatively generic CPU.

Is the JVM a upside or downside to Scala?
Yes, it's very efficient and that's not where the main problem lies. However, small allocations with modern C heap allocators like mimalloc or snmalloc has gotten extremely efficient as well. Would be interesting to see a benchmark comparison with Java's G1 and ZGC.

Z Garbage Collector: The Next Generation
Memory management for C is not itself a solved problem, not only is there a lot of performance to squeeze out of malloc itself (the benchmarks on https://github.com/microsoft/mimalloc exemplifies the variance between the implementations), but it's up to the programmer to implement memory management in the large in an efficient way, which is not an easy task. One sure mark of a slow C program is one with a ton of mallocs and frees strewn all over.

It's a very terse howto for replacing Factorio's memory allocator with Microsoft's mimalloc, and configuring mimalloc so that memory is always allocated on huge pages by using madvise().

Differences between Lean4 and Koka reference counting
I was wondering if Koka's perceus referencing counting style is any different from the reference counting that Lean4 implements? I understand that both rely upon the mimalloc (https://github.com/microsoft/mimalloc) library in the backend.

pmr implementation in c++14
If you are fine with heap allocations then there are only few dozens operator new/delete to override to regain control over normal C++ code memory use. Allocators and STL all need to call those. At least that's what gaming does on all platforms. If you need examples you can check Mimalloc on github ( https://github.com/microsoft/mimalloc/blob/master/include/mimalloc-new-delete.h ).
