Locating ‘identifiers’ quickly (ARM NEON edition)
A common problem in parsing is that you want to find all identifiers (e.g., variable names, function names) in a document quickly. There are typically some fixed rules. For example, it is common to allow ASCII letters and digits as well as characters like ‘_’ in the identifier, but to forbid some characters at the beginning of the identifier (such as digits). E.g., ab123 is an identifier but 123ab might not be.

But you got slots and ports and the ability to use it like a desktop computer — two computers in one! — and that was crucial because without any Dock, even the smaller Mini and MicroDocks, you had hardly any ports at all (MacBook Air has entered the chat). Docking was so important that Apple even intentionally gimped the 2300 by keeping the 100MHz 603e on a 32-bit bus to maintain Dock compatibility. Yet because Duos were irrepressibly cute, they turned up in many other TV shows and even movies, most notoriously Hackers: [...]

Growing Oxides On Silicon On The Road To DIY Semiconductors
Doing anything that requires measurements in nanometers is pretty difficult, and seems like it would require some pretty sophisticated equipment. But when the task at hand is growing oxide layers on silicon chips in preparation for making your own integrated circuits, it turns out that the old Mark 1 eyeball is all you need.
