In past articles, I've covered different ways to understand, analyze and improve the performance of your web applications. I've shown that between your network connections, server hardware, database design and HTTP server configuration, you can change and improve the performance of your web application—well, sort of.

This guide explains how you can set up an AoE target and an AoE initiator (client), both running CentOS 7. AoE stands for "ATA over Ethernet" and is a storage area network (SAN) protocol which allows AoE initiators to use storage devices on the (remote) AoE target using normal ethernet cabling. "Remote" in this case means "inside the same LAN" because AoE is not routable outside a LAN (this is a major difference compared to iSCSI). To the AoE initiator, the remote storage looks like a normal, locally-attached hard drive.

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.
