Universities have disinvested from their presses just as much as their libraries

publicbooks.org — At the university press where I work as an acquisitions editor, my email inbox is a reminder of how much authors care about their books—and with good reason. Scholarly books are the culmination of years of intensive research, writing, and revision, often with major personal and professional stakes. They are labors of love and many other feelings, too: excitement, anxiety, frustration. Many are written in hopes of getting a full-time faculty position, tenure and therefore long-term job security, or promotion. But that’s not always the case or the result, especially given the brutal adjunctification of the academic workforce. I wrote my own university press monograph while working full-time outside academia and hoping—for a while at least—to get a tenure-track job. That was before I started ... UNIVERSITIES, 5

Why does trying to break into the NT 3.1 kernel reboot my 486DX4 machine?

stackexchange.com — I installed Windows NT 3.1 on a Compaq ProSignia 3080 system, because of several reasons: I know that this machine was running Windows NT 3.1 when it was in productive use. And I think this machine was one of the machines Microsoft explicitly targeted with Windows NT. For improved performance, I maxed out the RAM at 128MB and swapped the socketed Intel 486DX-33 by an AMD enhanced 486DX4-SV8B (write-back cache and SMM) in a voltage adapter socket. I postponed dealing with BIOS support for 486DX4 processors, and jumpered the processor to a 2x multiplier. Without chipset support for L1 write-back and with a 2x multiplier, the processor is supposed to be software compatible to the Intel 80486DX2-66, which is a supported option for that system. WHY, 11

A Comparison of ARM Cortex-A Series Processor Performance Classifications

forlinx.net — In today's era of electronics, brands or appearances alone are no longer enough to tell the pros and cons of a product, and its built-in processors are naturally one of the criteria for distinguishing whether a product is high-end. So today we might as well take a good look at the more mainstream RAM processors in electronics in recent years. COMPARISON, 17
