Early days, but Hypervisor.framework patches are being built that allow QEMU to run an Arm build of Linux (and Windows) at native speed. https://twitter.com/jonmasters/status/1333555759737663489 The reality is tha

You are of course correct that the CA was announced then, but the news article was also about the fact that Let’s Encrypt had just turned five years old on the day that the article was published, and was a look back at what they have achiev

When I was a kid decades, we used to go sledding in the snow approximately every Christmas. These days snow is such a rarity that my kids have hardly ever seen snow in this country. They’ve gone sledding once or twice in their lives. Furthe

The bcc-tools ship a Clang/LLVM compiler to compile and build the BPF programs, which takes additional resources and adds a requirement for kernel headers to be installed on the machine. The libbpf-tools uses a compiler at build time (

The M1 is an Arm+ in the sense that it supports a stronger memory model option that plain Arm doesn’t, and it’s this feature that is used by Apple’s OS and the Rosetta translation engine that gives the performance boost for x86 translated p

As I said, the write up was quite interesting, so don’t take it the wrong way! A long read - including the journey taken to get there - can be educational itself (including wrong turns, proof of concepts etc). The only reason I posted the t

It looks like they were unlucky in the number of chargers stops they went to that were either not working or were already occupied. It does say that they didn’t want to use a 7kw charger because of the time it would have taken to charge it;

It is probably pretty safe. The issues that occurred are now widely known about and pilot training will include dealing with an MCAS issue, so an exact repeat is incredibly unlikely. Although the FAA and EASA have certified the Max as safe

Whoops! Yes, you’re right. I had misremembered its colour depth, but I recall it was bigger than the 256 colors of the VGA displays of the time. Unfortunately I can’t go back and edit the original post to fix. Thanks for correcting me!

It triggers mild OCD reactions for me, since there is inconsistency between the formatting of posts, a bit like missing apostrophes do, and as noted in a sibling comment affects how screen readers cover it. Perhaps keep it a mod only featur

The issue is that dispatch needs to know what’s running and to allow for the threads to effectively work with the thread schedule to service dispatch in an appropriate way. On macOS, the implementation is done in kernel, although there is a

Sure, but Delphi was released in 1995 as the first version, whereas this was something I was programming in 1992 (and I came late to the party with Nextstep 3). https://en.wikipedia.org/wiki/History_of_Delphi_(software)

At the time of NeXT’s heyday in the early ‘90s, most GUI programming was textual. You’d call add(button) and button.text = “Hello World” to build up your GUI, and have to wire up the events from your button to take specific actions. Quite a

There is very heavy integration between libdispatch and the kennel on macOS. In fact, when porting libdispatch to non macOS platforms for Swift on Linux, the developers were surprised that they couldn’t just unilaterally introduce changes i

The major downside of these “fleets” is that they will be able to be used to harass others but subsequently hide the evidence of that automatically after 24h.

The fact they are on the same package means that the electrical signals have a lot less far to travel from memory to cpu, and therefore you don’t have the signal losses or interference from the board having to route memory lines externally.

In this instance, Bannon gets away with it because he is white and shares political views of Zuckerberg. If an (e.g.) Muslim had said the same thing about a high profile (far)-right candidate, many of the people who supported his post would
