In computer architecture terms, the pub/sub system opens the door to more efficient communication in a multiprocessor system, since the data sharing is explicitly known by virtue of the subscriptions; furthermore, a sufficiently intelligent

Are you sure? All architectures I am aware of have mechanisms to do this in a branchless way. On my machine: int main(int argc, char argv) { int x = 0; x |= (argc != 1); return x; } Relevant portion of assembly (no optimi

I'm not understanding what underlying datastore you're referring to in the case of LINQ-to-Objects or LINQ-to-XML. These frameworks perform "queries" on ordinary objects or XML data stored in memory within the .Net process, not on some oth

Ideally, the tools should figure all this out. In practice, figuring out if there is enough work for parallelism to save you time is a hard problem, and programmer annotations help a lot. Additionally, PLINQ (parallel LINQ) in different t

True for LINQ to SQL, not so much for LINQ to Objects as evaluated in the benchmarks. Of course, one toy benchmark over 1k objects doesn't fully characterize its performance, but at least we don't have to worry about the database latency f

It comes from banking. In that context, $6MM stands for the Latin "6 mille mille," or "6 thousand thousands". $6M seems natural for those used to SI units (6 megadollars), but I have heard that in some financial circles that may be taken

I can recommend ExpressPCB, PCBExpress, and Sierra Circuits ProtoExpress ( http://www.protoexpress.com/ ) here. ProtoExpress, in particular, was pretty good in terms of price, specs (minimum trace/space, hole size, ability to do 4-layer

But is SunSpider multi-threaded?
253.
by sparky 16y ago
Yeah, the difference in representations could be a problem. I think a lot of it could be dealt with (with much difficulty) by the compiler -- for instance, you might be able to use the mantissa bits as a two's-complement int and synthesize

Their C backend, at least, uses doubles for all numbers. I initially thought many programs written that make nontrivial use of int s would be broken, but thinking about it a bit more, I suppose it's not a problem for 32-bit ints, since do

Agreed. When I worked at a fabless semi company, we compared ourselves to other fabless semi companies using this metric, and given similar levels of vertical integration, it's not a bad metric. Using it to compare a hedge fund and a fast

I'm guessing he means something like "when the user clicks, drags, and releases something, keep scrolling at the rate the mouse was moving at the release point only if the rate is above some threshold ." It'd be annoying if the mouse had

Were they with a label in 2003? If so, it is certainly reasonable that 100% of a small number (their take from "in Rainbows") could trump 1% of a large number (their take from "Hail to the Thief"). HTTT sold well upwards of a million copi

For the benefit of the philistines, what composable concurrency primitives does Haskell ca. 2005 have, and which would map well to an imperative OO language?

You're right, though I think the implementations differ in that Wolfire uses skeletons made of bones (line segments) and Pixar uses a polygonal cage mesh as the skeleton. It is quite possible that if you view the cage mesh as the 3D extrus

The article is about a vertex weighting system Pixar came up with to deform complex polygonal meshes to track simple skeleton meshes, like you need for character animation. The main problem they wanted to solve was limiting the sphere of i

The article discussed was this one in CACM (link is to discussion on Lambda the Ultimate) http://lambda-the-ultimate.org/node/3824 . I remember seeing it on HN too, but couldn't find the page immediately.

It helps that they sent out a forewarning email to all SX site owners telling them about the impending change; Andrew has an SX site. Still a great effort on Andrew's part to pull it together, thanks!

To be fair, all widely-used C compilers I am aware of have extensions to the C90 and C99 standards, which they accept as conformant code by default.

The founder of MO was on the SO podcast last week ( http://blog.stackoverflow.com/2010/03/podcast-86/ ), and they didn't seem to have any problem with it. They're pretty easy-going. That said, SO is trying to get VC funding, and their i
