It shouldn't, under the assumptions they are opening up with. Inverse square law twice is appropriate for an approximation that the reflection is entirely diffuse because you assum…

Some day we'll get CREATE TABLE ... ( ... STORAGE ORDER COLUMN MAJOR) to have our transactional cake on the tables that need it and eat our analytics cake on the tables that need t…

The vast majority of POI churn information comes from streetview + machine learning object detection + automatic change detection + human verification. There are many clever algori…

Repeating the exercise with something that is exactly representable in floating point like 1/8 instead of 1/10 highlights the difference.

They are very similar to the pros and cons of having a monorepo. It encourages information sharing and cross-linkage between related teams. This is simultaneously its biggest pro a…

You can't even express static rounding in C. You can't even express them in the LLVM language-independent IR. Any attempt to use the static rounding modes will necessarily involve …

Nothing major , just some oddball decisions here and there. Fused compare-and-branch only extends to the base integer instructions. Anything else needs to generate a value that fee…

Any argument that is filled with this much ragebait should be dismissed out of hand.

ISPC suffers from poor scatter and gather support in hardware. The direct result is that it is hard to make programs that scale in complexity without resorting to shenanigans. An i…

Shout-out to the NOAA GFS team, who publish the GFS analysis directly to AWS S3. https://registry.opendata.aws/noaa-gfs-bdp-pds/

clang-format and clang-tidy are both excellent for C and C++ (and protobuf, if your group uses it). Since they are based on the clang front-end, they naturally have full support fo…

LUTs are commonly used in geodesy applications on or near the Earth's surface. The full multipole model is used for orbital applications to account for the way that local lumpiness…

Exactly what order and degree were you using to evaluate the model? Variations in drag and solar pressure are more significant than the uncertainty in the gravity field for objects…

> "^integer" which is better than "int" I agree that it reads a little better. But as a small-handed person, it is unfortunately much more uncomfortable to type.

Shout-out to Firefox Multi-Account Containers, which Just Works (TM) for exactly this use case.

This comment is a fantastic example of the meta-battle which the tech industry has been waging. They have worked very hard to change the very questions in the privacy debate. In th…

Running multiple test builds in parallel isn't all that difficult, though. One with ubsan, one with asan, and one (opt-in on a test-by-test basis) with tsan.

Its even optional in ARMv7-A and Cortex-A9 doesn't have it.

Big family house in the suburbs with aggressive demand scheduling (ie, we let the temp float a fair amount when nobody is home) versus high-efficiency car.

For my case, it was worse. When normalized to dollars, I spent nearly 2x more in HVAC expenses compared to driving's fuel costs, and that's with a modest commute (20 miles). Its mu…
