Meanwhile, my ISP is offering me 17 Mbps. This is in the UK, in the centre of a "SuperConnected City". I use a phone hotspot for internet instead, because it's faster than any fixed line I can get.

The transforms are specified so you can position things perfectly these days, when aligned with screen pixels. Think of the compositing of layers of translucent windows used in modern 2d window managers, while dragging them around. Or even

I get 2 to 2.5 million IOPS for 4k random-reads on my personal server. Running Linux LVM software RAID over 3 x Samsung NVMe SSDs. That's not a read-write measurement, but it's a satisfying number for a not particularly high end

For what it's worth, exit() is not a syscall, but _exit() often is.

You can't use a smaller subnet than /64 for devices that use SLAAC for address allocation. (Unless you're putting them behind an IPv6 NAT, so thry can have their oen private /64).

Those IPv6 privacy extensions still reveal when the same node connects to a sequence of destinations within the address change interval, though. E.g. observers can see a single device connects to Facebook, OnlyFans, Pornhub and PayPal in th

It's not obvious that QEMU's JIT has to be a lot slower, but it is. It may be that Rosetta 2 is just more thoroughly engineered and tuned for Apple Silicon. Among other things, Rosetta 2 is able to use the CPU's special TSO

On my x86 MBP, I run GNU/Linux in VMWare Fusion, full screen. That gives me a combination of both worlds, which I can easily switch between with 4-finger swipe. I did battery life tests running the same Linux distro natively vs in a VM

Speaking for a friend. Yes there is, but quietly and slowly bootstrapped without publicity. Life events got in my friend's way so it's just as well they didn't take funding those years ago. VC in the UK is a pale shadow of

I've seen my Firefox process peak at 67GB (uncompressed) when viewing certain webapps, and it regularly goes over 16GB (uncompressed; about 10GB compressed). With only 16GB RAM that's too much swapping. It's slow due to the

There is a limit, but it depends on the materials and transistor geometry because those shape the potential wells, which affect tunelling. For example, high-κ dielectric materials. From Wikipedia: > As the thickness [of the gate insul

His claim to fame is making small ICs in his home garage while still a teenager, fairly recently. That's no small achievement. (He seems to have had access to the kind of garage and equipment other engineering kids can only dream of t

There are pros and cons, but here are a few things which favour stackful. Function coloring is a disadvantage of stackless (assuming it's mixed with regular, non-async C++ code). Async and non-async libraries can't interoperate t

Thread context switches don't flush the TLB either. This is an important performance optimisation in the kernel context switch code.

There are significant differences, because proof-of-work crypto mining is inherently a digital logic operation, so it's not amenable to photonic analog computing used for, e.g., approximate matrix multiplication and summation used in

Little known fact: Simulating quantum physical systems was the original motivation for building quantum computers, because those simulations are infeasible without one, and someone figured out it would be, in principle, feasible to run thos

I bought a high end MBP nearly 10 years ago with discrete GPU, thinking I would use it for numerical physics simulations, graphics development (I used to be a game engine dev), and maybe even games. Turns out in that nearly 10 years I'

Incognito isn't as private as the name suggests. I was surprised one day to open a tab in Incognito and see the site I visited knew who I was. That's because I had logged in to a related site in a tab I'd forgotten about in a

I agree, it is important to have at least two payment providers, ideally running them in parallel. It is still a problem if you're taking recurring payments, because you can't transfer customer payment details to the other when o

I agree that all it takes is one manager. Sometimes even when there are multiple managers and your line manager is ok, one nearby person in the org chart with enough influence over who is kept is enough to make everyone in their sphere more

I think you underestimate the number of developer type people who buy Apple laptops because of the great hardware (M1, screen, battery life, touchpad etc) and are comfortable with MacOS, but they are not Mac developers and would also be com

The general case adds ambiguity which makes it more of a design choice, rather than an obviously good generalisation. In the general case of 2 or more comma-separated arguments, is "func a, b" a call with two arguments, or a tuple

Syntax highlighting can help with distinctions like that. You might prefer Nim's visually distinct "let" for immutable, "var" for mutable. "const" is also available and means resolved to constant at compil

It doesn't need feedback from the type-checker. The type is not required, only whether a symbol is a type symbol. So it is enough to have feedback from the lexical scope, which can be tracked during parsing without any type analysis. I
