blog.rust-lang.org/inside-…022.html 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. https://aepicleak.com https://aepicleak.com/aepicleak.pdf https://github.com/IAIK/AEPIC 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. www.intel.com/content…657.html www.intel.com/content…pic.html -

Here's my conversation with John Carmack, legendary programmer & engineer. At over 5 hours, this is officially the longest conversation I've had on the podcast, and we can talk many more times. This was really fun and a huge honor for me. https://www.youtube.com/watch?v=I845O57ZSy4 -

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: twitter.com/OnChain…70382851 -

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: https://youtu.be/gp4U5aH_T6A More on this topic: https://t.me/technologique/1351 https://t.me/technologique/1490 https://t.me/technologique/1491 -

Interview of Lex Fridman with Michael Saylor (CEO of MicroStrategy) - Michael explained a lot of the crypto economy things clearly, one of the best explanations of crypto ideas and principles ever! https://www.youtube.com/watch?v=mC43pZkpTec -

Rust release 1.59.0 blog.rust-lang.org/2022/02…9.0.html Be aware that incremental compilation now off by default and should be enabled explicitly via set RUSTC_FORCE_INCREMENTAL=1environment variable. What's new:Cargoandrustcnow support stripping when the binary is linked, this can be enabled inCargo.toml. In generic types default values forconstgenerics can be specified now. Inline assembly in unsafe blocks viaasm!macro. #Rust -

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! https://github.com/CIUDSE #Rust -

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....

A really well written article, contains a weighted observation about advantages and disadvantages of both languages - definitely worth reading! https://pvs-studio.com/en/blog/posts/0733/ #Rust #CPP
