Obviously Rust needed more powerful abstractions, GAT (generic associated types) implementation stabilized, also going even further to HKT (higher kinded types, also referred as types of types, or type constructors), and dependent types, with following implementation of CoC (calculus of constructions).

And as a systems language there're a lot more things should be done to use Rust even more widely, espesially for embedded systems (automotive and aerospace sphere for example). For example, fault tolerance to run-time memory allocation exceptions in stdlib collections, dealing with infallible methods (panic on allocation failure in operations with collections), more improved error handling (to handle panics in main thread), and process recovering, after alloc errors, not yet fully supported in Rust stdlib's collections API (see this issue: https://github.com/rust-lang/rust/issues/29802).


Intel SGX and thus AWS Nitro enclaves are having vulnerability.

AES-NI and RSA keys easily leaked through APIC registrers and MMIO memory, i.e. through data transferring between L2 and L3 cache. This is Intel's architectural vulnerability, affecting 10, 11, 12 generation.

Microcode update (with registers and MMIO pages cleaning after every operation with enclave) is already on its way.
Also it's recommended to use MSR registers (x2APIC mode) instead of MMIO (xAPIC mode) to use and access APIC registers.

Really close example of the weakness of any L1 crypto liquidity ("beware of crypto whales", especially rightful for BTC):

What was happened with Terra (LUNA) and their TerraUSD (UST) stable coin and what became the reason why the whole crypto market is down now - really good analysis, which shows the weaknesses of the whole crypto market, especially for the altcoins, which has the paired stable coins and liquidity pools in BTC (which is true for the most of other coins) - read in this thread:

Must watch/listen episode of Lex Fridman podcast, especially in current situation on crypto market (which will alienate many people from decentralized cryptos, definitely, and then may swamp into the developed market of centralized proprietary digital currencies of central banks) - discussion about money, currencies, assets and values with a very solid person:

Rust release 1.59.0

https://blog.rust-lang.org/2022/02/24/Rust-1.59.0.html

Be aware that incremental compilation now off by default and should be enabled explicitly via set RUSTC_FORCE_INCREMENTAL=1 environment variable.

What's new:

Cargo and rustc now support stripping when the binary is linked, this can be enabled in Cargo.toml.

In generic types default values for const generics can be specified now.

Inline assembly in unsafe blocks via asm! macro.

One step to more wide application of Rust in aerospace sphere!
Obviously, there're a lot more things should be done to use Rust even more widely, espesially for embedded systems. For example, fault tolerance to run-time memory allocation exceptions in stdlib collections, dealing with infallible methods (panic on allocation failure in operations with collections), error handling, and process recovering, after alloc errors, not yet fully supported in Rust stdlib's collections API (see this issue: containers should provide some way to not panic on failed allocations · Issue #29802 · rust-lang/rust · GitHub)
But the Genie is already out of the bottle!
More things to come and that's will be huge!

Something unusual are happening with Facebook, Instagram and WhatsApp right now - they are completely not exist on the internet, even in BGP routing protocol! Facebook just un-internet itself.... Looks like a massive outage...

Great article by Leah Rowe, the founder of Libreboot project, for defend Richard Stallman.
Mainly all this fraudulent activity around FSF about displacement and exclusion of Richard Stallman is targeted and tried to reach only one goal - to move the FSF under control of Big Tech, as it happened previously with Linux Foundation and OSI.

Richard Stallman speech on a WebSummit in 2016, about current risks to freedom and privacy in nowadays in the internet and how to reclaim peoples freedom using free/libre open source software:

https://youtu.be/n9YDz-Iwgyw

Without Richard Matthew Stallman (aka RMS) there wouldn't be GNU project, without GNU there wouldn't be GNU/Linux and Linux kernel would be useless, without RMS and GNU there wouldn't be Free/Libre and Open Source Software communities and organizations as we know them - we must to remember the commitment of Richard Matthew Stallman for his groundbreaking work on GNU, we must be grateful and appreciate RMS for the Freedom in Software which we have today!

If you are truly support Free/Libre Open Source movement, use FLOSS in a daily work and in a daily life, and appreciate work of founding fathers in this movement - you are already part of this movement and community!
