64-bit nanosecond values are actually pretty common on Darwin already. See e.g. clock_gettime_nsec_np(3).
It might not be the memory concern it once was, but today it might very well be a power concern. Modern laptop display pipelines can save power if they don't have to redraw any of the screen: constantly updating status…
There's code for it in Darwin's libmalloc, but it's not exposed as API. reallocarray() has some difficulties as an interface, mostly inherited from realloc(). I'm a bigger fan of reallocarr(), but that's NetBSD only. We…
Until signal handlers get involved...
That won't be editable anymore. But you could disable SIP from recovery mode, make the change, then re-enable it.
Do you have a bug number, by chance? (If not, consider filing one at bugreporter.apple.com)
As far as "modern signal handling" goes: On OS X, you can also just create a dispatch source of type DISPATCH_SOURCE_TYPE_SIGNAL. If your code already uses dispatch, this is much easier than trying to wire up to kqueue…
I think the hesitations about passphrase being subject to brute force, rainbow table, etc. are warranted, but I have another concern: If my passphrase gets compromised, I have to retire the keypair. That's true of a key…
Thinking aloud: could one build a combination fossil fuel and solar steam-powered turbine? When the sun is out, you use (supercritical) steam as they describe being able to generate. If the sun goes away, you feed the…
Amazingly, this sort of use-after-free causes compatibility problems for allocator writers even today. Imagine if you change the implementation of malloc() such that smaller allocations get their own mmap() region…
Is this perhaps because ruby calls it a case statement instead of a switch statement?
Keep in mind: This class is part of a conservatory-style BFA program. These students are already, or will soon be, custom to public critiques. And learning how to accept public criticism, positive and negative, is…
It looks like there's a few different exemptions: http://www.dol.gov/whd/regs/compliance/whdfs36.htm
What? I'm pretty sure it's not available until the fall.
Go watch this video: http://www.heart.org/HEARTORG/CPRAndECC/HandsOnlyCPR/Hands-O... That's all you need to know as a lay-rescuer. And if you forget, the 911 operator will walk you through it. ( Or, if you'd rather:…
This seems like an intentionally misleading title. I think the many people who work in "no cameras" facilities might love the option of a camera phone with an employer's profile that makes the phone safe to bring into…
If you mmap a file, and then access the mmap'ed region, pulling in the pages of the file from disk is considered paging the file in. Watch the output of fs_usage to see examples of this.
"Hi there, I was retyping a link to my invoice and screwed up a digit. It took to someone else's page, which seems odd. For example, my link was <link> and I accidentally typed <other link>. Not sure if…
I wonder, is the glass just holding the phone at the right angle for the polarity of the phone's antenna and the available signal to match up? If so, this trick wouldn't likely work places other than that restaurant.
