Information security is challenging, and can be breathtakingly expensive in money and staff energy. Smaller organizations may not have the money or staffing expertise to do the job right, even when the need is the greatest. At OSCON 2016, Kelsey Gilmore-Innis of Sexual Health Innovations (SHI) gave a really interesting talk on how her small nonprofit has done some creative thinking about security, and how that influences the deployment and operation of their application. read more

This guide explains how to set up an NFS server and an NFS client on CentOS 7. NFS stands for Network File System; through NFS, a client can access (read, write) a remote share on an NFS server as if it was on the local hard disk.

Matrix Labs’ FPGA-driven “Matrix Creator” IoT daughter board for the Raspberry Pi 3 is loaded with sensors, 802.15.4 radios, and a mic array.

It could be said that this principle also extends to the Process Table, which I have discussed in previous articles in this series. Consider, for example, the treasure trove of gems to be found if you delve deeply into the “procfs” pseudo-filesystem, located in root level “/proc” on your filesystem.

Axiomtek’s “MANO0500” Mini-ITX board supports 6th Gen Intel Core, Pentium, and Celeron CPUs, and offers three SATA, two GbE, and mini-PCIe with SIM. Mini-ITX boards are typically among the first form-factors to support new Intel Core chips along with COM Express modules. We’re not sure why Axiomtek, one of the more prolific of embedded vendors, […]
