Capacity and speed requirements keep increasing for networking, but going from where are now to 100G networking isn’t a trivial matter, as Christopher Lameter and Fernando Garcia discussed recently in their LinuxCon Europe talk about the world of 100G networking. It may not be easy, but with recently developed machine learning algorithms combined with new, more powerful servers, the idea of 100G networking is becoming feasible and cost effective.
The idea of 100G networking is becoming feasible and cost effective. This talk gives an overview about the competing technologies in terms of technological differences and capabilities and then discusses the challenges of using various kernel interfaces to communicate at these high speeds.
Vim text editor turned 25 late last year – the first public iteration was launched on November 2, 1991, a couple of weeks after Linus Torvalds announced Linux. To celebrate Vim's anniversary, creator Bram Moolenaar recently dropped version 8.0.
Ordinarily the update of a text editor wouldn't be worth mentioning, but this is the first major Vim release in ten years. In today's world, where web browsers drop major point updates (what they consider major, anyway) several times a year, Vim's lack of major updates is not just refreshing, but speaks of an entirely different approach to developing software.
Even leaving aside the absurd version system of today's web browsers, eight releases in 25 years would be considered slow by today's software development standards. Interestingly, though, Vim's biggest rival, GNU Emacs, has a roughly similar development pace. GNU Emacs began life in the 1970s and is currently at version 25, which means it averages two releases to Vim's one, but still definitely on the slow side.
Learn-to-code site Code.org is apologising to its students after being caught by a database table maxing out, and dropping progress for an unknown number of participants.
In its mea-culpa blog post, the group says it was burned by a database table with a 32-bit index.
GCC 7 moved on to only bug/documentation fixes but an exception was granted to allow the BRIG front-end to land for AMD's HSA support in this year's GNU Compiler Collection update. As of this morning, the BRIG front-end has merged.
BRIG is the binary form of the Heterogeneous System Architecture Intermediate Language (HSA IL). This BRING front-end also brings the libhsail-rt run-time into GCC. So far BRIG in GCC has just been tested on Linux x86_64.
The best open source software 2017
The term ‘open source’ refers to software whose source code is freely available to download, edit, use and share. There are different types of open source license, which give users different degrees of freedom, but the main aim of open source is to encourage collaboration.
Open source software has lots of advantages over other ‘free’ options you’ll come across – even if you’re not a developer yourself. It’s usually maintained by a community and updated frequently to patch vulnerabilities or squish bugs as soon as they’re identified; there are no restrictions on commercial use, so you can happily use it for your home business; and the ability to edit the source means there’s often a wealth of user-created plugins available to download.
COM duo expands upon quad -A53/FPGA Zynq UltraScale+
Enclustra unveiled two Linux-ready COMs based on the quad-core Cortex-A53 based Zynq UltraScale+ ARM/FPGA SoC with DDR4 RAM up to 8GB.
Enclustra’s SODIMM-style Mars XU3 and larger Mercury+ XU1 computer-on-modules run Linux on the Xilinx Zynq UltraScale+ MPSoC. They follow Enclustra’s announcement earlier this month of a Linux-friendly Mercury+ AA1 COM running on an Intel/Altera Arria 10 ARM/FPGA hybrid. Enclustra offers several SODIMM-style Mars and larger Mercury COMs equipped with Altera and Xilinx FPGAs or FPGA/ARM hybrid SoCs, including the Altera Cyclone V based Mercury SA1.
