Introduction to MySQL Indexes Indexes in MySQL are database structures used to optimize data retrieval speed and efficiency. They are a roadmap that speeds up the process of finding specific rows in a large table. As such, index design must strike a balance between improved query speed and efficient data modification.

This blog post gives a glimpse of the computer systems research papers presented at the USENIX Annual Technical Conference (ATC) 2019, with an emphasis on systems that use new hardware architectures. Intel Quick Assist Technology (QAT) was the focus of the QZFS paper which used this new hardware device to speed up file system compression.

High-speed networks through 5G may represent the next generation of cord cutting. Rural connectivity is a persistent problem; many rural users (and some urban users) are still limited to dial-up speeds. But that’s also a problem that 5G vendors could solve; virtual LANs ( VLANs ) are hardly a new concept. I don’t, do you?
