And that would be true today as NZ is not currently allowing anyone without citizenship or a residency visa in at all (with some minor exemption for touring sports teams and the performing arts)

That's what we did on the old swap based systems, on modern paged systems we don't read pages in untill there is a page fault, to do that efficiently we need to align page boundaries with disk block boundaries - elf (and coff bef

I worked with a.out on early unixes and elf on later ones - not addressed here is the main reason for switching: ELF allowed you manage pages contiguously on disk so that they could be paged in directly (stuff can be page aligned within the

Well the US constitution explicitly allows slavery in this particular case, why not?

I did the same thing 40 years ago. Still hasn't grown back

I'm 63, literally up until 5 minutes ago I didn't realise that most people (or any people) actually see images when they imagine things, I'm quite flabbergasted, in retrospect it explains lots of things

Yes, NZ had 2 parties trading off power for decades until we got rid of the FPP system (like the US/UK), we now use MMP (the same as Germany) and we haven't had a government that wasn't a coalition since (even this time when

At what level of reality does it become a warcrime to turn it off?

cd arrived in the v7 Bourne shell, v6's shell was by Ken Thompson (it's just the name of the system call that cd calls)

heh - always sync twice - almost 40 years later my fingers still do that sometimes when I'm thinking .... (I used to port Unix for a living, early ports were always a tad unstable after that first prompt)

Were these normal punched cards? surely you could duplicate the deck on any card punch?

If you were lucky enough to have real core then you may not have had to toggle in bootstrap after powering on ...

I've certainly had situations where 'fibers' made more sense - a verilog runtime system with literally millions of them (where the compiler can figure out exactly how much space 99% of the fibers need - so stack sizes of 12 b

Also I designed a Mac graphics accelerator gate array back in the late 80s, we were worried that the promised VRAM performance would not be fast enough so I designed in the ability to add extra clocks to RAS and CAS timings - it ran at full

We had a Burroughs 6700, at some point (late 70s) we agreed to pay for what was called the "$50,000 screwdriver" which upped the clock speed - we wrote a contract where we would run a benchmark before and after and if it wasn&#x2

Here in New Zealand most banks no longer provide paper statements. I have a US Etrade account, recently they wanted a paper statement of any sort and I realised that I no longer receive anything that meets that requirement (I could turn sta

I'm not an expert but I've seem them characterised as "the return of Cray vectors", so maybe yes

The E version only has half as many registers
951.
by Taniwha 5y ago
you have to include the branch instruction too in any comparison

The main distinction is that the 16-bit RISCV-C ISA exactly maps to existing 32-bit RISCV instructions, its implementation only occurs in the decode pipe stage
953.
by Taniwha 5y ago
Yeah but the code required for an overflow check is just one extra instruction (3 rather than 2)
954.
by Taniwha 5y ago
So this is one tiny corner of the ISA, not something that makes ALL instruction sequences longer - essentially RISCV has no condition codes (they're a bit of an architectural nightmare for everyone doing any more than the simplest CPU

Endianness within bytes (or words) is actually a thing - IBM long numbered bits from the most significant starting with 0 (think of 360s and the like, not PCs) - there are modern chips with registers numbered the same way (a current family

I'm not sure that there exist 'safety' glasses that would actually be safer in this situation
957.
by Taniwha 5y ago
yup, but I'm using it as an example to make a point here (hence my use of the word 'naive') - also the whole point of doing async stuff is that you don't have to worry about 'ticks'

More importantly unlike other DNS providers (like the root servers) it censors the domain names that it will resolve, Sony's argument is that because it chooses some domains it should censor the ones that it wants too

Well to some extent metastability is a result of having a clock (and the tiny feedback loops that we embed in synchronous flops to create storage) - instead you use logic structures that are designed to be asynchronous and that can adjust t

Well for example imagine you have a 64-bit adder - and you add two numbers together - let's assume that on e of the in puts is '1' - how long does it take until the output is stable? it depends on the second value an d more
