While the Linux 3.16 kernel is now stable, a few days ago the Reiser4 file-system was finally ported to Linux 3.15.
Edward Shishkin released Reiser4 for the Linux 3.15.1 kernel last weekend. Besides being ported to the kernel interface changes for Linux 3.15, there's also two bug-fixes for the out-of-tree file-system. Most of the Reiser4 activity these days continues to just be porting to new kernel versions and bug-fixing. Edward is down to being one of the only main developers left and there's expected to be no effort to mainline the controversial file-system without the support of a major Linux ISV/IHV.
IBM says the channel is in dire need of more professionals with mainframe server administration expertise, and just in time for the new school year, it is promoting a partnership with the Linux Foundation, Marist College and Syracuse University to deliver those skills through a new series of MOOCs on open source operating systems.
So 2038 brings the end of time for 32bit architectures. It being some
twenty four years ahead, it may seem like there is plenty of time for folks
to migrate to 64bit architectures that are (mostly) unaffected by this
issue. However, 32bit processors are still being produced today in
extremely high volumes, and many of those systems are being used in
commercial, industrial and medical environments, where these systems may be
quite literally embedded into the walls and machinery and are expected to
run for 25 years or more. As these small systems become more and more
pervasive, the risks of major trouble in 2038 grow. And thatâs to say
nothing of the impact on future classic-car resale prices for fancy cars
like the Tesla when the high end in-dash display wonât work (gasp!).
MYIR announced a sandwich-style single board computer that runs Linux on a Freescale i.MX28x SoC and features -40 to 85°C operation and a CAN bus interface.
MYIR specializes in low-power ARM single board computers (SBCs) and computer-on-modules (COMs), with the latter including the MYC-SAM9X5-V2 (using Atmel’s ARM9-based AT91SAM9X5) and MYC-AM335X (using TI’s Cortex-A8 based Sitara AM335x). With the new MYC-IMX28X COM and associated MYD-IMX28X development board, the company is mining the Freescale i.MX28x, a 454MHz, ARM9 system-on-chip that has been used in many embedded Linux boards, most recently including Technologic’s TS-7400-V2.
Windows and Linux communities used to virtually battle each other regarding the superiority of one platform or the other, but that is no longer happening, at least not at the same scale. One of the reasons for that might be that Linux is actually gaining ground.
Back in 2011, Nvidia announced to the world that they had acquired a license for the latest ARM instruction set, the ARM v8. But the most exciting part of the deal was that the new ARM instruction set is 64-bit. After making 32-bit mobile CPUs, Nvidia was set to take their Tegra K1 platform to the next level with a 64-bit mobile CPU. At the Hot Chips conference this year, Nvidia revealed their little project that they have been quietly working in for all these year. The Tegra K1 ARM v8 64-bit chip from Nvidia is ready for a release later next year. The new chip is codenamed Project Denver.
NI’s new 4-slot CompactRIO control system combines a dual-core Atom E3825 with a Kintex-7 FPGA, and features industrial temperatures and NI Real-Time Linux.
The National Instruments (NI) “CompactRIO 4-slot Performance Controller” is the high end “performance” big brother to NI’s “value” CompactRIO cRIO-9068 model, introduced a year ago. Whereas the cRIO-9068 runs NI Linux Real-Time OS on a Xilinx ARM+FPGA hybrid Zynq-7020 system-on-chip, the new CompactRIO splits processing duty between an Intel Atom processor and a higher-end Xilinx Kintex-7 325T FPGA. The CompactRIO uses a dual-core, 1.33GHz Atom E3825 SoC from the latest, 22nm Bay-Trail-I generation, featuring a relatively low, 6 Watt TDP.
