Choosing the right tool for multiple jobs can be tough. There are countless brands to choose from, and each one offers hundreds of tools with various models that often look identical. Earlier this year, I finally bought a Ryobi High-Torque Impact Wrench, and not only is it the tool upgrade I needed, but it's something everyone should own.

LAS VEGAS โ After spending nearly two hours trying to impress the crowd with new LLMs, advanced AI chips, and autonomous agents, Amazon Web Services CEO Matt Garman showed that the quickest way to a developerโs heart isnโt a neural network. Itโs a discount.
One of the loudest cheers at the AWS re:Invent keynote Tuesday was for Database Savings Plans, a mundane but much-needed update that promises to cut bills by up to 35% across database services like Aurora, RDS, and DynamoDB in exchange for a one-year commitment.
The reaction illustrated a familiar tension for cloud customers: Even as tech giants introduce increasingly sophisticated AI tools, many companies and developers are still wrestling with the basic challenge of managing costs for core services.
The new savings plans address the issue by offering flexibility that didnโt exist before, letting developers switch database engines or move regions without losing their discount.ย
โAWS Database Savings Plans: Six Years of Complaining Finally Pays Off,โ is the headline from the charmingly sardonic and reliably snarky Corey Quinn of Last Week in AWS, who specializes in reducing AWS bills as the chief cloud economist at Duckbill.
Quinn called the new โbetter than it has any right to beโ because it covers a wider range of services than expected, but he pointed out several key drawbacks: the plans are limited to one-year terms (meaning you canโt lock in bigger savings for three years), they exclude older instance generations, and they do not apply to storage or backup costs.
He also cited the lack of EC2 (Elastic Cloud Compute) coverage, calling the inability to move spending between computing and databases a missed opportunity for flexibility.
But the database pricing wasnโt the only basic upgrade to get a big reaction. For example, the crowd also cheered loudly for Lambda durable functions, a feature that lets serverless code pause and wait for long-running background tasks without failing.
Garman made these announcements as part of a new re:Invent gimmick: a 10-minute sprint through 25 non-AI product launches, complete with an on-stage shot clock. The bit was a nod to the breadth of AWS, and to the fact that not everyone in the audience came for AI news.
He announced the Database Savings Plans in the final seconds, as the clock ticked down to zero. And based on the way he set it up, Garman knew it was going to be a hit โ describing it as โone last thing that I think all of you are going to love.โ
While Black Friday is one of the biggest shopping days of the year, Home Depot isn't slowing down and still has epic tool deals for Cyber Monday and beyond. While there are several available, if you're looking to stock up on Milwaukee battery packs, one deal in particular caught my attention.
Are you an aspiring mechanic or someone who prefers to fix things yourself? If so, having the right tools can make all the difference. In fact, having the wrong tool or not having what you need can be the difference between a quick job and spending hours fighting nuts and bolts. So, here are a few must-have Ryobi tools for at-home auto repairs.
Sometimes you need to know what temperature something is, but you donโt quite want to touch it. At times like these, you might want a temp gun on hand to get a good reading, like the one [Arnov Sharma] built.
The build is a relatively simple one, and is based around an Waveshare ESP32 C6 development module that comes with a small LCD screen out of the box. The microcontroller is set up to read an MLX90614 infrared temperature sensor. This device picks up the infrared energy that is emitted by objects relative to their temperature. The sensor has a great rangeโfrom -70 C to 380 C. The readouts from this sensor are then displayed on the screen. Battery power is from a small 600 mAh LiPo cell, which is managed by a IP5306 charge module.
Itโs worth noting that these infrared temperature sensors arenโt infallible devices. The temperature they perceive is based on certain assumptions about factors like an objects emissivity. Thus, they donโt always give accurate readings on metallic or shiny objects, for example. Itโs also important to understand the sensorโs field of view. Despite many commercial versions featuring a laser pointer for aiming, many of these infrared temperature sensors tend to average their reading over a small spot that gets larger the farther away they are from the object being measured.

While AI bubble talk fills the air these days, with fears of overinvestment that could pop at any time, something of a contradiction is brewing on the ground: Companies like Google and OpenAI can barely build infrastructure fast enough to fill their AI needs.
During an all-hands meeting earlier this month, Googleโs AI infrastructure head Amin Vahdat told employees that the company must double its serving capacity every six months to meet demand for artificial intelligence services, reports CNBC. The comments show a rare look at what Google executives are telling its own employees internally. Vahdat, a vice president at Google Cloud, presented slides to its employees showing the company needs to scale โthe next 1000x in 4-5 years.โ
While a thousandfold increase in compute capacity sounds ambitious by itself, Vahdat noted some key constraints: Google needs to be able to deliver this increase in capability, compute, and storage networking โfor essentially the same cost and increasingly, the same power, the same energy level,โ he told employees during the meeting. โIt wonโt be easy but through collaboration and co-design, weโre going to get there.โ
As you know, there are plenty of automation tools out there, but most of them are closed-source, cloud-only services that charge you per operation and keep your data on their servers. For those of us who value privacy and transparency, these solutions simply wonโt do. Thatโs where n8n comes into the picture โ a free, private workflow automation platform that you can self-host on your own infrastructure while maintaining complete control over your data.
In this article, we explore n8n, set it up on a Raspberry Pi, and create a workflow for monitoring security news and sending it to Matrix. Letโs get rolling!
What is n8n?
n8n is a workflow automation platform that combines AI capabilities with business process automation, giving technical teams the flexibility of code with the speed of no-code. The platform uses a visual node-based interface where each node represents a specific action, for example, reading an RSS feed, sending a message, querying a database, or calling an API. When you connect these nodes, you create a workflow that executes automatically based on triggers you define.
With over 400 integrations, native AI capabilities, and a fair-code license, n8n lets you build powerful automation while maintaining full control over your data and deployments.
The Scenario: RSS Feed Monitoring with Matrix Notifications
For this tutorial, weโre going to build a practical workflow that many security professionals and tech enthusiasts need: automatically monitoring RSS feeds from security news sites and threat intelligence sources, then sending new articles directly to a Matrix chat room. Matrix is an open-source, decentralized communication protocolโessentially a privacy-focused alternative to Slack or Discord that you can self-host.
Step #1: Installing n8n on Raspberry Pi
Letโs get started by setting up n8n on your Raspberry Pi. First, we need to install Docker, which is the easiest way to run n8n on a Raspberry Pi. SSH into your Pi and run these commands:
pi> curl -fsSL https://get.docker.com -o get-docker.sh pi> sudo sh get-docker.sh pi> sudo usermod -aG docker pi
Log out and back in for the group changes to take effect. Now we can run n8n with Docker in a dedicated directory:
This command runs n8n as a background service that automatically restarts if it crashes or when your Pi reboots. It maps port 5678 so you can access the n8n interface, and it creates a persistent volume at /opt/n8n/data to store your workflows and credentials so they survive container restarts. Also, the service doesnโt require an HTTPS connection; HTTP is enough.
Give it a minute to download and start, then open your web browser and navigate to http://your-raspberry-pi-ip:5678. You should see the n8n welcome screen asking you to create your first account.
Step #2: Understanding the n8n Interface
Once youโre logged in and have created your first workflow, youโll see the n8n canvasโa blank workspace where youโll build your workflows. The interface is intuitive, but let me walk you through the key elements.
On the right side, youโll see a list of available nodes organized by category (Tab key). These are the building blocks of your workflows. There are trigger nodes that start your workflow (like RSS Feed Trigger, Webhook, or Schedule), action nodes that perform specific tasks (like HTTP Request or Function), and logic nodes that control flow (like IF conditions and Switch statements).
The main canvas in the center is where youโll drag and drop nodes and connect them. Each connection represents data flowing from one node to the next. When a workflow executes, data passes through each node in sequence, getting transformed and processed along the way.
Step #3: Creating Your First Workflow โ RSS to Matrix
Now letโs build our RSS monitoring workflow. Click the โAdd workflowโ button to create a new workflow. Give it a meaningful name like โSecurity RSS to Matrixโ.
Weโll start by adding our trigger node. Click the plus icon on the canvas and search for โRSS Feed Triggerโ. Select it and youโll see the node configuration panel open on the right side.
In the RSS Feed Trigger node configuration, you need to specify the RSS feed URL you want to monitor. For this example, letโs use the Hackers-Arise feed.
The RSS Feed Trigger has several important settings. The Poll Times setting determines how often n8n checks the feed for new items. You can set it to check every hour, every day, or on a custom schedule. For a security news feed, checking every hour makes sense, so you get timely notifications without overwhelming your Matrix room.
Click โExecute Nodeโ to test it. You should see the latest articles from the feed appear in the output panel. Each article contains data like title, link, publication date, and sometimes the author. This data will flow to the next nodes in your workflow.
Step #4: Configuring Matrix Integration
Now we need to add the Matrix node to send these articles to your Matrix room. Click the plus icon to add a new node and search for โMatrixโ. Select the Matrix node and โCreate a messageโ as the action.
Before we can use the Matrix node, we need to set up credentials. Click on โCredential to connect withโ and select โCreate Newโ. Youโll need to provide your Matrix homeserver URL, your Matrix username, and password or access token.
Now comes the interesting partโcomposing the message. n8n uses expressions to pull data from previous nodes. In the message field, you can reference data from the RSS Feed Trigger using expressions like {{ $json.title }} and {{ $json.link }}.
Hereโs a good message template that formats the RSS articles nicely:
Click the โExecute Workflowโ button at the top. You should see the workflow execute, data flow through the nodes, and if everything is configured correctly, a message will appear in your Matrix room with the latest RSS article.
Once youโve confirmed the workflow works correctly, activate it by clicking the toggle switch at the top of the workflow editor.
The workflow is now running automatically! The RSS Feed Trigger will check for new articles according to the schedule you configured, and each new article will be sent to your Matrix room.
Summary
The workflow we built today, monitoring RSS feeds and sending security news to Matrix, demonstrates n8nโs practical value. Whether youโre aggregating threat intelligence, monitoring your infrastructure, managing your home lab, or just staying on top of technology news, n8n can eliminate the tedious manual work that consumes so much of our time.
