Custom HTTP headers : naming conventions
...ion here is whether there are conventions for (B). There are. They involve grouping the parameters together alphabetically, and separating them from the many standards-relevant headers of type (A). Using the "X-" or "X-ACME-" prefix is convenient and legitimate for (B), and does not conflict with (A...
How do emulators work and how are they written? [closed]
... this compiled code and execute it. Then when you hit a given instruction group again, you only have to execute the code from the cache. (BTW, most people don't actually make a list of instructions but compile them to machine code on the fly -- this makes it more difficult to optimize, but that's ...
What is “entropy and information gain”?
...ate, imagine the task of learning to classify first-names into male/female groups. That is given a list of names each labeled with either m or f, we want to learn a model that fits the data and can be used to predict the gender of a new unseen first-name.

Why do x86-64 instructions on 32-bit registers zero the upper part of the full 64-bit register?
... has to issue in a cycle by itself, while AL merging can be part of a full group.) Haswell/SKL doesn't rename AL separately from RAX at all, so mov al, [mem] is a micro-fused load+ALU-merge, only renaming AH, and an AH-merging uop still issues alone. The partial-flag merging mechanisms in these CP...
