IoT Security, Privacy Vital from the Outset

For any new technology to be trusted, it must be secure. That is why privacy and security are essential to the development of new technologies from the outset. They must not be an afterthought.

This is especially so for the Internet of Things (IoT) and the plethora of devices that are now available. These devices are gradually being integrated into daily life as we enjoy the benefits they bring. In a number of cases, we are also increasing our dependence on them, such as fitness monitors and home automation.

But poorly-secured IoT devices and services can serve as entry points for cyber attacks, compromising sensitive data and potentially threatening the safety of individual users, as well others.

Attacks on infrastructure and other users, fueled by networks of poorly-secured IoT devices, can affect the delivery of essential services such as healthcare and basic utilities, put the security and privacy of others at risk, and threaten the resilience of the Internet globally.

As concerns mount about the need for regulating the ecosystem and policymakers around the world consider ways to secure it throughout its product lifecycles, it is important to consider the risks this fast-growing technology poses, as well as what steps Continue reading

How to manage your Linux environment

The configuration of your user account on a Linux system simplifies your use of the system in a multitude of ways. You can run commands without knowing where they're located. You can reuse previously run commands without worrying how the system is keeping track of them. You can look at your email, view man pages, and get back to your home directory easily no matter where you might have wandered off to in the file system. And, when needed, you can tweak your account settings so that it works even more to your liking.Linux environment settings come from a series of files — some are system-wide (meaning they affect all user accounts) and some are configured in files that are sitting in your home directory. The system-wide settings take effect when you log in and local ones take effect right afterwards, so the changes that you make in your account will override system-wide settings. For bash users, these files include these system files:To read this article in full, please click here

As memory prices plummet, PCIe is poised to overtake SATA for SSDs

A collapse in NAND memory prices and a closing of the price gap between PCI Express-based and SATA-based solid-state drives (SSDs) means the shift to PCIe SSDs will accelerate in 2019, with the newer, faster format replacing the old by years' end.According to the Taiwanese tech publication DigiTimes (the stories are now archived and unavailable without a subscription), falling NAND flash prices continue to drag down SSD prices further, which will drive the adoption of SSDs in enterprise and data center applications. This, in turn, will further drive the adoption of PCI Express drives, which are a superior format to SATA.To read this article in full, please click here

BrandPost: Robots in Retail are Real… and so is Edge Computing

I’ve seen plenty of articles touting the promise of edge computing technologies like AI and robotics in retail brick & mortar, but it wasn’t until this past weekend that I had my first encounter with an actual robot in a retail store. I was doing my usual weekly grocery shopping at my local Stop & Shop, and who comes strolling down the aisle, but…. Marty… the autonomous robot. He was friendly looking with his big googly eyes and was wearing a sign that explained he was there for safety, and that he was monitoring the aisles to report spills, debris, and other hazards to employees to improve my shopping experience. He caught the attention of most of the shoppers.To read this article in full, please click here

? The Wrangler CLI: Deploying Rust with WASM on Cloudflare Workers

? The Wrangler CLI: Deploying Rust with WASM on Cloudflare Workers

Today, we're open sourcing and announcing wrangler, a CLI tool for building, previewing, and publishing Rust and WebAssembly Cloudflare Workers.

If that sounds like some word salad to you, that's a reasonable reaction. All three of the technologies involved are relatively new and upcoming: WebAssembly, Rust, and Cloudflare Workers.

Why WebAssembly?

Cloudflare's mission is to help build a better Internet. We see Workers as an extension of the already incredibly powerful Web Platform, where JavaScript has allowed users to go from building small bits of interactivity, to building full applications. Node.js first extended this from the client to the server- unifying web application development around a single language – JavaScript. By choosing to use V8 isolates (the technology that powers both Node.js and the most popular browser, Chrome), we sought to make its Workers product a fully compatible, new platform for the Web, eliding the distinction between server and client. By leveraging its large global network of servers, Workers allows users to run code as close as possible to end users, eliminating the latency associated server-side logic or large client-side bundles.

But not everyone wants to write Continue reading

When I Knew Cloudflare Was the Right Place For Me

When I Knew Cloudflare Was the Right Place For Me

Let’s be honest, interviewing for a new job can be a long, difficult process. Not only is it emotionally draining to handle multiple rejections, slow responses, and prolonged processes, it can be physically exhausting to sit through hours of stale interviews. A former colleague of mine compared interviewing to navigating a jungle; one misstep here, one wrong answer there, and you barely make it out alive. I once had an interviewer set out a 200-piece puzzle for me to complete in order to “evaluate my problem solving skills”. Basically, when it comes to interviews, you never know what you are going to get. As you may be able to tell, my feelings towards finding a new job this past fall were grim, until I interviewed with Cloudflare.

If you truly want to be impressed by Cloudflare, interview with them. Every employee knows the process is deliberate, thoughtful, and diverse in taking the time to get to know a candidate while the candidate gets to know Cloudflare. It is humbling to realize that any employee interviewing has also passed through this challenging process. It all starts with a phone call, as most interviews do, and the process is fairly standard until Continue reading

Motorola taps CBRS spectrum to create private broadband LMR system

In a move that could upend how workers access data in the enterprise, Motorola has announced a broadband product that it says will deliver data at double the capacity and four-times the range of Wi-Fi for end users. The handheld, walkie-talkie-like device, called Mototrbo Nitro, will, importantly, also include a voice channel. “Business-critical voice with private broadband data,” as Motorola describes it on its website.The company sees the product being implemented in traditional, moving-around, voice communications environments, such as factories and warehouses, that increasingly need data supplementation, too. A shop floor that has an electronically delivered repair manual, with included video demonstration, could be one example. Video could be two-way, even.To read this article in full, please click here
