Newlib is a very popular libc targeting embedded systems. It’s the libc that ships with the GNU Arm Embedded Toolchain published by ARM. This article takes a look at one of the commonly used functions provided by the Newlib C library: memcpy. We’ll examine the default nano implementation and the performance implications, comparing it against the faster non-default implementation. Like Interrupt?

Internet Of Things has always played a significant role in the retail industry, stocking and warehousing. And its value is projected to rise from USD 14.5 billion in 2020 to USD 35.5 billion by 2025, at a CAGR of 19.6% The term Internet of Things was coined by Kevin Ashton when he was faced with a challenge in logistics and supply chain management while he co-founded the MIT Auto-CAD centre.
Data is at the heart of every business today. But if we don’t understand the data or if the data isn’t accessible, it doesn’t do us much good. More important than the data itself is having the right data in the hands of the right people who can execute at the right time. This need has given rise to edge computing, which helps businesses glean insights from data by processing it as close to the source as possible.
Canonical and DFI announce that the GHF51 and EC90A-GH, have been certified, based on the latest AMD-based platform. Both offer improved performance, a smaller footprint, and full access to open-source software with Ubuntu and Ubuntu Core. These are part of the first wave of products that passed the Ubuntu IoT hardware certification.
A typical IoT application with any physical system or process in the field can have hundreds of on-site sensors generating copious amounts of data every second and possibly communicating in several different protocols.
It’s official! We’re excited to announce that Ivanti has acquired an industrial internet of things (IIOT) platform from the WIIO Group. WIIO is one of Ivanti Wavelink’s channel partners and is based in Paris, France.
The 2010 Stuxnet malicious software attack on a uranium enrichment plant in Iran had all the twists and turns of a spy thriller. The plant was air gapped (not connected to the internet) so it couldn’t be targeted directly by an outsider. Instead, the attackers infected five of the plant’s partner organizations, hoping that an engineer from one of them would unknowingly introduce the malware to the network via a thumb drive.
We recently had a hackathon at Grafana Labs. Anyone who wanted could get several work days without normal responsibilities to do whatever they found meaningful in the wider Grafana community and/or Grafana Labs commercial offerings. This allowed me to invest some time into Kraken, a project designed for reading out different sensors, and to update it for modern hardware and libraries.
