An Early Look At Some PHP 7.4 Performance Benchmarks

The initial PHP 7.4 Alpha 1 release is just two weeks away already... Curious about the performance of this yearly update to PHP7, I ran some benchmarks on the latest development code as of this morning compared to the earlier PHP7 releases and even PHP-8.0 that is in development on Git master. PHP 7.4 has been working on preloading options, short closures, custom object serialization, FFI work that didn't end up making it for PHP 7.3, the null coalescing assignment operator has been added, and various other changes. The PHP 7.4 alpha releases are supposed to kick off on 6 June while the betas will then fire up starting on 18 July followed by at least six release candidates beginning at the end of August. If all goes well, PHP 7.4.0 will make its debut around the end of November or early December. PHP-7.4 has been branched since January while PHP-8.0 development is on Git master for that next major PHP8 release with JIT functionality and other changes in the works. Read more

Bringing the Benefits of Linux Containers to Operational Technology

Linux container technology was introduced more than a decade ago and has recently jumped in adoption in IT environments. However, the OT (operational technology) environments, typically made up of heterogenous embedded systems, have lagged in the adoption of container technologies, due to both the unique technology requirements and the business models that relied on proprietary systems. In this article, I explore recent innovation in open-source offerings that are enabling the use of containers in OT use cases, such as industrial control systems, IoT gateways, medical devices, Radio Access Network (RAN) products and network appliances. Enterprise IT leaders have adopted “cloud-native” computing architectures because of the innovation velocity and cost benefits derived by the approach. To leverage containers, developers segment applications into modular micro-services that enable flexible development and deployment models. These micro-services are then deployed as containers where the service itself is integrated with the required libraries and functions. On containerization, these application components have small footprints and fast speeds of deployment. The applications become highly portable across compute architectures due to the abstraction away from the hardware and the operating system. Read more

Open-spec Omega2 LTE SBC features Cat 4 and GNSS

Onion’s $99, sandwich-style Omega2 LTE SBC for remote sensor applications with a MIPS-based, WiFi-enabled Omega2S+ compute module, a Quectel EC25 chipset with LTE Cat 4 and GNSS, plus USB Type-C, microSD, and battery support. Last December, Onion updated its MIPS-based, WiFi-enabled Omega2 board with a similarly OpenWrt-driven Omega2 Pro SBC that increased RAM to 512MB and flash to 8GB and added real-world USB host and micro-USB ports. Now, the company has returned to Crowd Supply with a similarly open source, OpenWrt Linux driven Omega2 LTE model with 4G LTE and GNSS location connectivity. Pricing ranges from $99 for the board alone to $199 for a fully loaded “Ultimate Collection” kit, all with early August shipments. Read more
