Yeah, as distance (latency) to RAM increases, the amount of on-die cache increases (another handy way to distribute heat with a performance bonus) and coherency becomes more costly, so in effect it becomes the core-specific RAM you mention.

I don't think there's much NUMA action on single socket at the moment, but as CPU area increases and more of the transistors are not actually doing CPU work (to spread out the heat-making bits) which increases distances on a singl

Routes are back! Bit of a BGP blip there. Nothing to worry about. It's not like anyone's been practising attacks on fundamental Internet infrastructure.

DNS is fine. Routes are gone. Seeing the same in Sydney and Dallas. Pretty worrying.

The ARM world is rapidly moving towards UEFI, partly thanks to Microsoft insisting there be something like it for them to build on. Even better, u-boot implements enough of it to boot a UEFI operating system. So on some new devices you&#x27

Any distro that complies with the GPL will generalise its requirements to everything else, and thus host original sources for every single package. :-)

It's "acceptable-throughput" for that use case, and you can balance the tradeoffs of compilation time to optimisation (for time or code size) by adding -On parameters. That's a very different kind of throughput to "

ELB is HAproxy. :-) Sure, you get a lot of flexibility configuring HAproxy yourself, but you also have to run it yourself. 90% of the time it's easier to just use ELB (plus it has some direct integration with other services, like IAM

dry run for cfn == create change set :-) (also, it helps to use nested stacks)

Now that is a properly researched and presented well-actually! Thanks, this is cool. :-)

I wonder if the acceptance of complexity in page zeroing was more about mapping and zeroing multiple pages… which makes me curious about DragonflyBSD's approach to that, as well as zeroing superpages.

by jdub 10y ago
Yes, Linux (and Windows for that matter) does everything DragonflyBSD just removed.

When a program needs memory, the operating system maps a physical page of memory (4KB in most cases) into its virtual memory space. That page might have been in use by a different program only moments before, so the new program could go pok

You'd have to implement your own stack unwinding in a bare metal context, if you wanted it at all, yeah.

The copyright of seL4 was not given (or licensed) to OK Labs AFAIK. It's currently owned by General Dynamics, and OK Labs no longer exists.

by jdub 10y ago
Nitpick: It was NICTA's (now Data61 at CSIRO) seL4 that was verified, not OK Labs' OKL4. The seL4 copyright is owned by General Dynamics.

It's not developer class desktop hardware, at least for native code. Good for all kinds of things, but doesn't satisfy what the author is looking for.

Sure there is, but it's quite reasonably smaller and/or less visible than a social movement standing against a fundamental existential threat.

Yes, state cops on the beat have pistols. The special AFP officers who guard parliament house (who replaced private security contractors) have submachine guns.

It was fairly controversial when the Australian Government recently decided to have submachine gun-armed Federal Police provide security at our national Parliament House. It was rationalised by claims of terrorist threats, of course. To an
