That stage1 example is pretty ugly - using __builtin_ia32<x> would work, but they are the only things harder to read than the intrinsics themselves! Plus there are some intrinsics that are just macros, (sets, masks, etc), and you don&

Solves and creates different issues. With FMV you essentially have to build the compile unit with the highest level of microarch support so that the pre-processor interprets the intrinsics headers and doesn't eliminate intrinsics you m

The article only touches on the more troubling of NZ fault lines - if the Alpine Fault ruptures, or "unzips" as it is commonly referred to, then really bad things will happen. M8+ earthquakes and major changes to the rest of the S

Mostly the latter. They have large - and growing - offices right in the middle of the Sydney CBD.

'sudo rmdir'? I don't think that does what they think it does.

I wish we'd used it for a recent senior c++ dev hire. And this was an internal hire. They were just way too good at playing the game and it took us way too long to get rid of the person - fired, not just dumped.

Honest question from an interested party: have you actually had it alert you about someone else changing the files? I've been in the previous boat: of having it running on a system I've inherited, and given up because it seemed to

Junos has run on x86 for years - Juniper had i686 control planes in some devices. As well as PPC and a few different kinds of MIPS (Octeon, XLR) - although those are usually data plane. Newer products use virtualization, i.e. running the Fr

Yeah, it is interesting, as the other big RE listings player in Australia also has a tech blog: http://tech.domain.com.au/ realestate.com.au is Murdoch, in fact, but was a Melbourne startup many years ago.

I think when I looked single instr crc32 was ~5 times faster than the pclmulqdq version. As an aside, if they have a server in production that doesn't support CLMUL, they should junk that machine - it appeared in Westmere and Bulldozer

That $15 vs $150 comparison is stupid - where I can buy a A9 for $15? The A9 is a great jump forward by Apple - and I'm impressed by my iPhone 6s - but I'm yet to see the "crushing" benchmark, except for those that are s

Content blocking requires an ARMv8 processor (so 5S and later) - must be a requirement of whatever they are using for regex.

There's a few problems with that chart, but the one that jumps out is that there is no Intel Core i5-4660. Might be a typo, but makes you question the attention to detail.

The graph would be even more complex if you trace all the part acquisitions and divestitures in and out of Avago (LSI, PLX, Infineon, Axxia, SSD tech to Seagate, Emulex). Then again, Broadcom liked to buy things, for example ServerWorks, Re

Proper fenders and racks, or clip on ones that fall off if you look at them the wrong way? We don't need a Waze-alike - Strava heatmaps already do it. Cyclists are pretty good at finding the most efficient paths.

So many WTF, so little time. They designed a carbon frame and fork for a commuter bike, going through the huge time and money sink that is creating their own moulds (plus need at least one per frame size and they are expensive) and it doesn

I'd also suggest adding --track-origins=yes for uninitialized scans - it might be a bit slower, but is very useful for nailing these things quickly. We make sure all of our unit tests run clean under valgrind, including the unit testin
