The last days of Unix

Filed under
OS

Unix, the core server operating system in enterprise networks for decades, now finds itself in a slow, inexorable decline. IDC predicts that Unix server revenue will slide from $10.2 billion in 2012 to $8.7 billion in 2017, and Gartner sees Unix market share slipping from 16% in 2012 to 9% in 2017.

Jean Bozman, research vice president at IDC Enterprise Server Group, attributes the decline to platform migration issues; competition from Linux and Microsoft; more efficient hardware with more powerful processor cores, which is less expensive and requires less maintenance; and the abundance of Unix-specific apps that can now also run on competitor’s servers.

New Arduino boards include first FPGA model

Arduino launched a “MKR Vidor 4000” board with a SAMA21 MCU and Cyclone 10 FPGA, as well as an “Uno WiFi Rev 2” with an ATmega4809 MCU. Both boards have a crypto chip and ESP32-based WiFi module. In conjunction with this weekend’s Maker Faire Bay Area, Arduino launched two Arduino boards that are due to ship at the end of June. The MKR Vidor 4000 is the first Arduino board equipped with an field programmable . The Intel Cyclone 10 FPGA. will be supported with programming libraries and a new visual editor. The Arduino Uno WiFi Rev 2, meanwhile, revises the Arduino Uno WiFi with a new Microchip ATmega4809 MCU. It also advances to an ESP32-based u-blox NINA-W102 WiFi module, which is also found on the Vidor 4000. Read more

DragonFlyBSD 5.3 Works Towards Performance Improvements

Given that DragonFlyBSD recently landed some SMP performance improvements and other performance optimizations in its kernel for 5.3-DEVELOPMENT but as well finished tidying up its Spectre mitigation, this weekend I spent some time running some benchmarks on DragonFlyBSD 5.2 and 5.3-DEVELOPMENT to see how the performance has shifted for an Intel Xeon system.
