The internet of things (IoT) remains a popular subset of the information technology (IT) realm. However, despite its advancements, IoT is still in its infancy. By 2027, the global IoT market is estimated to be worth over $1,463.19 billion USD.
With massive leaps in IoT technology and a rapidly changing landscape, IoT security is a budding concern. Here's what you need to know about IoT security.
While loads of digital video game vendors exist, Valve reigns supreme as arguably the most popular. Its Steam Link hardware debuted in 2015 as a means of streaming Steam games from a PC over a home network. This in-home streaming feature allowed for playing video games on a TV or projector for a console experience with PC gaming. However, in 2018, Valve halted production of the Steam Link. Alternatives such as the third-party Moonlight or Parsec for game streaming exist. But Valve released its own Steam Link app for Android, as well as the Raspberry Pi 3. Learn how to install the Steam Link app for Steam streaming on the Raspberry Pi 4, 3, or 3 B+ for the ultimate Raspberry Pi gaming build!
Often, particularly in the maker community, the term open source gets thrown around. There's open-source hardware and open-source software. Many Linux operating systems (OSes) for instance are open-source. But there's also free and open-source. Learn all about what open-source is, the difference between free and open, why you should contribute to open-source communities and projects, plus more!
Recently, I was performing some server maintenance on my home lab, a Lenovo ThinkServer TS140 running Ubuntu that I have as a dedicated Plex media server. When I first set it up, I installed Ubuntu 16.04 LTS and I finally decided to upgrade from 16.04 to Ubuntu 20.04. However, when I attempted to run a full operating system (OS) upgrade, I got an error that there was not enough space. As such, I realized that I'd need to clean the boot partition. Learn how to free up more space in boot on Ubuntu, and why your Ubuntu boot partition may be full!
On Ubuntu and other Debian-based Linux distributions (distros), the boot partition stores various files required to boot up your OS. The boot partition is mounted to the aptly-named /boot directory. Among the various files you'll find in your Ubuntu Linux boot partition are GRUB bootloader configuration files.
The Raspberry Pi has a ton of different uses. Since it's small and energy-efficient, uses such as a network-attached storage (NAS) device, media server, game server, smart home hub, or any number of Internet of Things (IoT) projects run extremely well on the Raspberry Pi. Since the credit-card-sized Raspberry Pi sports a tiny footprint and sips power, it's ideal for an always-on device. And with superb internet connectivity, whether running on a wireless network or via a wired Ethernet port, the Pi is suitable for handling network traffic. Learn how to build a Raspberry Pi VPN (virtual private network) server!
Ok, so what is a VPN? It's a virtual private network, a means of connecting to the internet with a secure, private connection. Rather than using your IP address, network traffic is routed through a gateway server, so you'll have a public-facing IP address of another location. For instance, you might be located in New York City, but with your VPN, making it look as if you're connecting in London, UK.
Linux is an awesome ecosystem for a variety of uses. For instance, Linux is the de facto server environment, powering over 96% of the top 1 million servers. And for programming, Linux is arguably better than Windows. Check out the best Linux distros for programmers and developers!
My Linux journey began back in the day when I inherited an ancient Shuttle XPC desktop sans an operating system (OS). Rather than purchasing a copy of Windows, I decided to install the Ubuntu derivative Lubuntu, and since then I've been a convert. Likewise, one of the reasons many motivations for programmers to use a Linux OS is that it's free and open-source.
