I have spent several years as a Team Leader (also known as an Engineering Manager), heading up teams of about 4–6 developers from different backgrounds, seniority levels, and abilities. The first time I led a team was during my army service as an officer in the elite 8200 unit.
As a QA an important part of your tasks consists of continuous improvement of your Test and delivery process. Being a key member of your organisation you will have to participate in different workshops, meetings and trainings in order to figure out the best balance you and your team can
As I sat in my office, staring blankly at the computer screen in front of me, I couldn't help but feel a sense of disappointment and frustration wash over me. It had been a month since I was passed over for the position of R&D Director,
Returning back home. I get this buzz on my phone. Turns out it’s an email from Linode. Daym. I thought was I billed already? Trust me on this, I was really not sure what to do of this for the first two minutes when I read the email. I
Keep your server safe with a few extra steps. SSH is essential to server management. This post will walk you though some of the options available to harden OpenSSH. The instructions may work for other flavors of Linux but is intended fro Ubuntu 16.04 LTS. Warning: Messing with how
The Criticality of Security One of the most discussed issues related to the Internet of Things (IoT) is security. From agriculture to hospitals, from residential smart homes to commercial smart buildings, and from power stations to traffic management systems, IoT systems and technologies will touch many parts of the world
Bluetooth Smart is an emerging short range wireless technology aimed for low power devices. Bluetooth 4.2 core specification provides various methods to secure the communication between devices and establish trusted connections. This paper describes the design considerations to secure the Bluetooth smart devices. 1. Introduction Bluetooth smart (also known
For the past few months, I’ve been playing around with the new Web Bluetooth API which is about to ship in Chrome 56 in February 2017. And let me tell you, this new feature just unlocked lots of new possibilities for the Web. As a Web Advocate, I was
A Short Introduction Web Bluetooth is a a new technology that connects the Web with the Internet of Things. Web Bluetooth is so new, it’s still being built and prototyped! But of course, that doesn’t mean we can’t play with it… Essentially, Web Bluetooth lets you control
First things first Beacon technology provides location data much like GPS. But beacons are not a replacement for GPS technology. While the actual workings of the two technologies vary drastically, the end result is similar. The main selling point of beacons is their ability to provide a user’s location
An iBeacon app relies on an active Bluetooth connection to detect the beacons around it. Without bluetooth, the app wouldn’t know when to trigger certain location related features. Handling bluetooth settings and permissions on the iPhone can sometimes be tricky. If you don’t request permissions correct and check
Low Energy Bluetooth (BLE) is widely used in various smart devices and IoT scenarios as a low-power, short-range wireless communication technology. However, due to the characteristics of BLE, it is susceptible to various security threats. Therefore, when designing and developing BLE applications, it is crucial to focus on security issues
In the physical layer of the Bluetooth protocol stack, there are two useful parameters: LQI and RSSI. Both are used by the receiver to evaluate the current wireless environment quality (link quality) and guide subsequent actions. However, the calculation principles and application scenarios of these two values differ significantly. LQI
Smart cards have become an indispensable part of our daily lives, used in various applications such as finance, transportation, and identity verification. At the heart of smart card technology lies the Secure Element (SE) and the 7816 protocol, which together form the foundation of security and reliability. In this blog
As computer communication professionals, we are well aware of the significance of wireless communication protocols in today's connected world. Among the numerous wireless protocols available, Zigbee has emerged as a popular choice for low-power, low-data-rate applications. In this blog post, we will delve into the details of the
As the Internet of Things (IoT) continues to grow, the need for efficient and reliable data transfer between devices has become increasingly important. One approach to achieve this is by emulating the Universal Serial Bus (USB) protocol over Bluetooth Low Energy (BLE) technology. In this blog, we will explore the
