x86 is an ancient design mired in legacy and problems, so Intel/AMD Intel and AMD had to make it work for a modern world even if that involved kludges, band-aids, and crutches. Whilst you do have a point there, personally I do not find

Sun was one of the few RISC design houses who stubbornly resisted NUMA in favour of SMP, which they have perfected in the hardware and in the software (Solaris). The «Solaris internals» book discusses the subject of SMP vs NUMA vs ccNUMA in

Well. The Latin version of Roman is Romanus, which is believed to have descended from Romulus, one of the two legendary founders of Rome. The popularity of Roman in Eastern and Western Slavic cultures is likely due to the cultural influence

I see Swift as a more approachable version of Rust. If somebody is mulling over Rust but finds it too difficult to grasp, they could start off with Swift first and then move over to Rust. One of the main advantages of Rust is a more develop

Not just interoperability with Objective C but with C (full) and C++ (increasingly better but not full) as well. Swift is also interoperable with different versions of itself courtesy of the Swift stable ABI (Application Binary Interface)[0

The vast majority of virtual machines, including JVM and .NET, are stack based. And, whilst compiling C and C++ the JVM / .NET CLR byte codes is very uncommon, both VM's have become very popular compilation targets for other progr

Once again – respectfully – this remains largely twaddle as the facts themselves state otherwise. Even at the microarchitecture level, the hard part is not raw CISC-ness but irregularity and compatibility baggage. In that respect x86 was us

by inkyoto 7mo ago
Respectfully, this is nonsense. «More CISC-y» does not by itself mean «harder to optimise for». For compilers, what matters far more is how regular the ISA is: how uniform the register file is, how consistent the condition codes are, how pr

PDP-11 was a major source of inspiration for m68k architecture designers. The influence can be seen in multiple places, starting from the orthogonal ISA design down to instruction mnemonics. It is quite likely that not allowing the misalign

PDP-11, m68k – to name a few, did not allow misaligned access to anything that was not a byte. Neither are RISC nor modern.

The math is a bit off. One day amounts to 24 hours. Assuming no overtime, one day translates into 3x 8 hour shifts, or 3x engineers. Suddenly, $260k a year buys 3x engineers. Now, assuming that the dark factory stuff can actually work as co

Given that linguistics does not have a concept of what makes a language «hard» or not, the language hardness classification is highly subjective and perceptional. I have already commented on why I do not think that Cantonese tones are hard,
