What Is Raspberry Pi and How Can I Use It for My Home Internet?
A Raspberry Pi computer can do a little of everything, including keeping you occupied if you need a new project (or distraction). This teeny-tiny computer not only clocks in at a low price, but could potentially help you trim costs by becoming a DIY router. Saving money is appealing: A recent CNET survey showed that internet costs spiked for 63% of US adults last year. When our budgets are tight, having a device that can cover the gamut is appealing, from hosting your home internet to providing a platform for your next gaming experience. What was once a simple tool for teaching students about computers has become a fun tech experience for computer lovers everywhere. Not familiar with a Raspberry Pi computer? Let's take a closer look at these pocket-sized machines. What is a Raspberry Pi computer? Raspberry Pi is a tiny, inexpensive computer about the size of a credit card. It was initially developed in the UK to teach school kids about computer science. As the single-board computer has become more popular over the years, people have used it for various projects. It has evolved into newer, better versions with Bluetooth and Wi-Fi capabilities, and its price has kept falling. Raspberry Pi computers don't have hard drives — they don't have much at all — but this is why they're great starting points for people who want a project. They have ports so you can plug in a monitor and keyboard, as well as a microSD card, and once you've installed an operating system, you can use the Raspberry Pi as a full-fledged desktop computer. The Raspberry Pi 5 is the most recent iteration, with a 16GB model that launched in January. It has a 2.4GHz quad-core 64-bit ARM Cortex-A76 CPU and a VideoCore VII GPU, a significant upgrade from the Pi 4. It's also available in 2GB, 4GB and 8GB, with prices from $50 to $120. The Raspberry Pi Zero is the most minimal model, retailing for only a few dollars. While it can still run many of the same functions as the other Pis, it doesn't run nearly as smoothly (or as quickly) as the ones with more RAM. Locating local internet providers What is Raspberry Pi mostly used for? Raspberry Pi isn't most people's first choice for a desktop computer. You're most likely getting this computer if you want to tinker with it or have another project in mind. However, Raspberry Pi can function as your primary computer. Popular ways people use their Raspberry Pi include as gaming consoles, running their smart devices and as internet routers. In terms of gaming, one option is to configure your Pi for throwback games with RetroPie, an open-source software that works with any Raspberry Pi. You can also link a Raspberry Pi computer with your smart devices to conveniently control your lighting, TVs and more. You can also use it as a router for home internet (more on that later). The uses and capabilities of this tiny computer are endless, and a quick Google search will turn up even more ideas you can do with it. Why would I use a Raspberry Pi computer? Many people use Raspberry Pi computers because they enjoy the thrill of building a computer and like the uniqueness of what Raspberry Pi provides. Truthfully, there is no specific reason to use a Raspberry Pi computer versus any other computer or machine. Various other devices exist in much the same way. It is often about the novelty that this one provides. If you surf through the Raspberry Pi subreddit or the Raspberry Pi Forums — both of which are packed full of Raspberry Pi folks, from novices to pros — you'll find thread after thread of people discussing their Raspberry Pi projects, big and small. Within the discussions, you'll see notes on how they're using the pocket-sized computer, why they're doing it, advice and more. All of this is to say that you'll often use a Raspberry Pi computer because it's fun and a challenge. It was originally created as a teaching tool, and it continues to be a great learning device for anyone who wants to understand more about computers without breaking the bank. Plus, you can do some cool things with them. As you figure out all the uses of your Raspberry Pi, you may want to reward yourself with some raspberry treats. Getty Images Is it safe to use a Raspberry Pi computer? Regarding security issues, a Raspberry Pi computer is relatively safe, though it has risks. Then again, so does any desktop or laptop. Where you run into some trouble with a Raspberry Pi is the Linux operating system it runs on, because it uses a microSD card. That leaves your computer a bit vulnerable (though the open-source Linux is quite solid and many prefer it to any other OS) because someone could simply walk away with the microSD card, as a DZone report points out. You can ensure that your Raspberry Pi is more secure internally and physically by encrypting the device and making it more difficult to steal your information. It's highly recommended that you do this (much like you'd do with any computer to prevent hacking or data breach) but, in general, Raspberry Pi is no more vulnerable than other computers. Can Raspberry Pi help my home internet? Your Raspberry Pi can be used as an internet router on your home network, though admittedly, the Pi is better equipped to handle smaller networks. Some Raspberry Pi users have found more success as a travel router because it functions better as a Wi-Fi tool or hotspot in small use cases. But don't worry, you can still use it at home for your internet. There are a few handy guides to set up your Pi for internet access at home. These will essentially walk you through the process of ensuring your Pi is up to date, has the right software and can bridge between networks. This guide on Medium turns your Raspberry Pi into a Wi-Fi router, and this Raspberry Pi YouTube video shows how to add Ethernet to your Pi. Finally, a Raspberry Pi 5 can also be turned into a Wi-Fi extender using this handy guide. Raspberry Pi FAQ What are popular Raspberry Pi projects? Many people use Raspberry Pi for retro gaming consoles, controlling smart home devices and as a media center. You can also use it as a desktop computer if you install an operating system. Is it safe to use Raspberry Pi? A Raspberry Pi computer operates like any other computer, with an operating system and an internet connection that is as secure as you make it. You are responsible for taking the necessary measures to ensure the security of your information.

Remote SSH for IoT Devices Behind a Firewall – Step-by-Step Tutorial
Achieving a safe and reliable remote access IoT behind a firewall can seem complicated especially when your IoT devices are on private networks or behind stringent firewalls. However, with proper planning, SSH IoT behind the firewall can be set up securely without compromising your network safety. This guide will lead you to accomplish remote SSH access through practical steps without intricate networking. Picture yourself running an IoT controller, a smart sensor, or a Raspberry Pi at a remote location. You need to monitor performance, push updates, or troubleshoot, but the device is behind a NAT router or a firewall. The traditional port forwarding is not ideal as it is unsafe and exposes your network to significant threats. The enhanced option? Understanding how to enable SSH IoT behind a firewall in a modern way. Before you begin, ensure the following are available: Any functioning IoT device (like Raspberry Pi, Arduino with Linux, etc.) The device must have internet access. SSH must be enabled and installed on your device. Desktop/laptop with SSH client like PuTTY for Windows or Terminal on MacOS/Linux. Let us start by enabling SSH on the IoT device: For Raspberry Pi: Take the SD card and put it in your computer. Go to the boot partition and create a file named ssh (make sure to leave the extension blank). Remove the SD card and put it into the Pi, then turn on the Pi. Your Pi will now accept SSH connections. Check that your device is linked to the same local network. Use SSH to connect to it and ensure everything is functioning as it should. For We have now reached the part that requires some thought – how do you securely have remote access to IoT behind the firewall? Below are the most reliable choices: Reversing the SSH Tunnel inverts the normal SSH connection. The IoT device will phone out to a machine that you manage, such as a cloud VPS, thereby evading the firewall. RemoteIoT is an easy-to-use cloud platform which makes it simple for you to access your IoT devices without having to adjust your firewall. This method is best for those who don't want to deal with network configurations and custom scripts. A VPN (Virtual Private Network) allows a device to connect to the PC virtually as if both were in the same locality. Once connected, it is possible to SSH (Secure Shell) as if you were part of the same Local Area Network (LAN). As with any SSH IoT behind firewall configuration, security can never be overlooked. How to secure your connection: Implement SSH keys for authentication instead of passwords Turn off root logins Alter the default SSH port (if permitted by the firewall) Update the software on your device Ensure connection from a different location Set automatic reboots or watchdogs for the devices in case disconnection occurs. Maintain logs of usage for easy tracking and auditing. Remote access IoT behind firewall is manageable. With technologies like Remote IoT, reverse SSH, VPN, managing IoT devices has been simplified, secured, and made more efficient than before. There are several ways to facilitate secure access to multiple devices such as employing reliable remote access services or a central server. Secure remote SSH access is only a few clicks away.

Uptime Industries wants to boost localized AI usage with an 'AI-in-a-box' called Lemony AI
Uptime Industries is taking a bet on on-premise AI infrastructure with an "AI-in-a-box" handheld device called Lemony AI. The size of a sandwich, Lemony AI can supposedly run a large language model (LLM), AI agents and AI workflows all on one node. Each Lemony requires only 65 watts of power to run, the equivalent of charging a laptop, and can be stacked and connected to form bigger AI clusters. Sascha Buehrle, co-founder and CEO of Uptime, told TechCrunch that each node can sustain an LLM up to 75 billion parameters in size, and can host open-source models or retrofitted versions of closed models. In a cluster of Lemony nodes, each device can run a different model. Uptime is launching with partnerships with IBM and JetBrains to provide its customers easier access to AI models, including IBM's closed models. Like most tech startups, the idea for Lemony AI stemmed from a side project: Uptime's co-founders, Buehrle and Ivan Kuleshov, were trying to figure out if they could distribute language models on Raspberry Pi's micro computers, and while this wasn't originally related to generative AI, when it worked, they started trying to see what else these Raspberry Pis could handle. When they realized running models on local devices could prove the key to unlock more AI adoption by organizations — say, enterprises that don't want to use cloud-based models — they started building a device of their own. They figured going small with an emphasis on data privacy could get companies to adopt AI quicker. "We need to build something small which can go easily into the teams, and which [does] not require any organization-wide decision making — bringing on-premise generative AI solutions into the business teams, basically," Buehrle said. Clusters of small and powerful devices can help the system grow according to a customer's needs, he added. The company says it has already seen strong demand from business in heavily-regulated industries like finance, healthcare and law. "Everything stays in your box," Buehrle said. "So your documents, your files, your emails — the models are hosted in the box, the agents are running locally in the box, and nothing is leaving the box." Uptime has so far raised $2 million in a seed funding round led by True Ventures, with participation from Alumni Ventures, JetBrains, and some angel investors. The company will use the funds to further develop its devices. The startup says the plan now is to get the software it has developed for its micro AI computers, Lemony OS, to work on other companies' hardware, like the Nvidia DGX Spark. It also wants to expand the software from its current, single-user focus to one that can be used by teams. Lemony AI costs $499 a month to use, and can be accessed by up to five users.
