What happens when you turn a computer on?

Working on a computer is so easy nowadays that we find even children handling them expertly. However, several things start to happen when we turn on the power to a computer, before it can present the nice user-friendly graphical user interface (GUI) screen that we call the desktop. In a UNIX-like operating system, the computer goes through a process of booting, BIOS, Master Boot Record, Bootstrap Loading, grub, init, before reaching the operating level. Booting As soon as you switch on the Read more [...]

Connect with a New Type of Li-Fi

Many of us are stuck with slow Wi-Fi, and eagerly waiting for light-based communications to be commercialized, as Li-Fi promises to be more than 100 times faster than the Wi-Fi connections we use today. As advertised so far, most Li-Fi systems depend on the LED bulb to transmit data using visible light. However, this implies limitations on the technology being applied to systems working outside the lab. Therefore, researchers are now using a different type of Li-Fi using infrared light instead.

Python Libraries for Machine Learning

Machine learning helps with many practical applications, suitably augmented by deep learning and with extensions of the overall field of artificial intelligence. Many people, with the help of analytics and statistics, are busy navigating the vast universe of deep or machine learning, artificial intelligence, and big data. However, they do not really have to qualify as data scientists, as popular machine learning libraries in Python are available. Machine learning is promoting deep learning and Read more [...]

Raspberry Pi to Displace the Business PC

For a business establishment, maintaining PCs for each of their several hundred employees can be an expensive proposition. It is much simpler and cheaper to have a centralized workstation with several thin clients connecting to it. The ubiquitous single board computer, the Raspberry Pi (RBPi) is a suitable component for use as such a thin client. As the low cost of the Raspberry Pi makes it a very attractive proposition for use as a thin client computer, Citrix is offering an HDX Ready Pi to replace Read more [...]

RX300 – The Windows 10 Thin Client with the Raspberry Pi

The Raspberry Pi (RBPi) has no hard disk, is stateless, and can work as a desktop terminal, which makes it an ideal candidate for use as a thin client. It connects to the data center for all its applications, sensitive data, memory, and runs a Remote Desktop Protocol such as the Windows Terminal Services. That makes the RBPi a virtual desktop computing model, as it runs virtualization software, and accesses hard drives in the data center. Thin client computing has thin clients, software services, Read more [...]

Tinker Board: Raspberry Pi Competitor from ASUS

The community of single board computer users is passionate and the DIY enthusiasts are growing daily. While they are infatuated with the amazingly tiny package called the Raspberry Pi (RBPi), they are constantly clamoring for more performance and connectivity features. This demand has produced several competitors to the RBPi, and the tech giant, ASUS Computers is now providing one in the form of a Tinker Board. The ASUS Computers product is a mini-PC based on the ARM core, and its actual model Read more [...]

How Do You Count People Using Wi-Fi?

Other than providing wireless communication facilities, Wi-Fi can have other uses as well. Researchers at the UCSB are now experimenting with a common wireless signal to tell them the number of people present in a designated space. Astonishingly, these people need not be carrying any personal devices on them. At Professor Yasamin Mostofi’s lab in the UC, Santa Barbara, researchers are demonstrating that wireless signals have more uses than simply providing access to the Internet. With a Wi-Fi Read more [...]

Pi-Top: Convert your Raspberry Pi into a Laptop

Although we call the Raspberry Pi or RBPi as a single board computer and it is small enough to fit in your pocket, it is hardly useful as a computer when you are on the move. This is mainly because the SBC comes without a keyboard, display, and mouse, intended to keep the costs down. However, if you are interested in turning your RBPi3 into a laptop, there is the Pi-Top. You get everything necessary to turn your $35 single board computer into a laptop. For instance, you get a 13.3” HD LCD screen Read more [...]

PINE64 : A 64-bit Contender for the Raspberry Pi

Earlier, a DIY computing project could cost an enthusiast hundreds of dollars. Now, with single board computers such as the Raspberry Pi or RBPi or its latest kin, the Raspberry Pi Zero, anyone can start a new project at the cost of a cup of coffee. Seen from the other side of the fence, a competitor has to include a better choice of components, offer a better price or both. PINE64 Inc. has taken the third route. PINE54 Inc. is attempting to improve on the legacy so far built up by the RBPi. According Read more [...]

Thin Clients with the Raspberry Pi

When deploying a large number of computers at a single location, it is a common practice to employ thin clients. In such cases, several client computers access a powerful central server computer that controls resources such as the hard disk data and Internet access. The logical operating system of the server is isolated from the clients accessing it via a concept known as desktop virtualization. Implementation of desktop virtualization or VDI follows several conceptual models. One can broadly Read more [...]
