Very few TVs use IPS, since IPS tends to have worse black levels and pixel response time than PVA/MVA (alternatively: it's more expensive to get equivalent specs out of IPS), which are the two specs that TV reviewers care about (black level

But the buffering is not required because of the HDMI link; a display could update each pixel as it receives it over HDMI, just like CRTs did. LCDs buffer at least one frame for many reasons, but "because HDMI requires it" is not among them

Not everyone is in a relationship. The forcing is due to money - if you're poor enough, then you simply can't afford even a studio and are forced into having roommates to split the cost of rent.

No, the compiler couldn't have kept resVal in a register because it doesn't know resVal doesn't alias with any of val1..val7. Therefore, it must store resVal each iteration, and it must load each of val1..val7 each iteration. Otherwise,

No, it got lucky because it's emitting exactly what the author wrote; there's nothing complex going on. In fact, I'm sure the author is stunting where it got smart and hoisted val1+val2+val3+val4+val5+val6+val7 outside of the loop, and it c

That's... not really subtle. That's like pipelining 101. Which is nearly 30 years old now... The only weird thing there is the compiler lucks out in generating a version that allows OoOE to save the programmer from themself.

The only stack-specific special optimization that's done is fusing the decrement/increment of esp/rsp with the store µop. And that's done mainly since push/pop are one byte opcodes, unlike general load/store. Everything else is general memo

Unless I'm mistaken, he only compares the fees for stores. And looking at http://pages.ebay.com/help/sell/fees.html#if_fixed , it seems that for individuals, the new fixed fee of 10% is always worse for anything electronic or $100 or more.

It isn't; there are very few flags that allow the compiler to perform optimizations not allowed by the language standard. Aliasing is not one of them for any compiler I know of. In fact, there are usually flags to go the opposite direction

There's ChrUbuntu, which is easy to install but gives a barely functional trackpad, no sound, and a 75% chance of hanging on wake. Supposedly 13.04 is significantly better, but upgrading is stupidly hard and I've yet to manage to do so (cur

Well, I guess the sensor could theoretically be made using the entirety of a wafer. But it would be useless since the lens needed for such a large sensor would be more than the size and weight of a large ground telescope.

1.8 Gpixel sensors don't exist, due to physics. It's combining 368 sensors. No one stores or transmits uncompressed video outside of RAM. 15Mbps is decent for 1080p24, so 1.8 Gpixel 24fps would be decent at 15Gbps. Assuming say 14 hours of

It's kind of interesting how every teacher I've talked to that's taught for a decade or three agrees that NCLB is awful, yet among the general populace (HN comments), that's considered more evidence that teachers are incompetents. Possibly
