Most of us will never get a chance to drive a Ferrari F50 around the Nürburgring in real life, but we can all do so in a racing sim. To get the most out of that experience, many people build serious and elaborate racing sim rigs. What if one could use their racing sim rig […] The post Using a racing sim rig with a real RC car appeared first on Arduino Blog.
We’re excited to introduce the new Image Map Widget in Arduino Cloud! This powerful feature allows you to overlay live data onto an image, creating interactive and highly visual dashboards. Whether you’re managing a factory floor, an office space, or a piece of industrial equipment, this widget brings your data to life in a whole […] The post Introducing the Image Map widget: A smarter way to visualize your data appeared first on Arduino Blog.
A conventional model rocket engine is simple combustible solid fuel (black powder or more advanced composites) molded into a cylinder that uses expanding gas to produce thrust. Though it is minimal, there is some danger there. An alternative is compressed gas, which will also expand to produce thrust — just without the explosive chemical reaction. […] The post A homemade launchpad for compressed air-powered rockets appeared first on Arduino Blog.
Today’s digital slot machines are anything but “fair,” in the way that most of us understand that word. There is tight regulation in most places, but the machines can still adjust their odds of payout in order to maintain a specific profit margin. If the machine thinks it has paid out too many wins recently, […] The post This student made his own odds with a DIY slot machine appeared first on Arduino Blog.
Safes are designed specifically to be impenetrable — that’s kind of the whole point. That’s great when you need to protect something, but it is a real problem when you forget the combination to your safe or when a safe’s combination becomes lost to history. In such situations, Charles McNall’s safe-cracking autodialer device can help. […] The post Forgot your safe combination? This Arduino-controlled autodialer can crack it for you appeared first on Arduino Blog.

Around 2003, my mother had a laptop: the Compaq Armada 1592DT. It ran Windows Me, the worst Windows to ever exist, whopping 96 MB of RAM, and a 3 GB hard drive. My mother used it for important stuff, and I played games on it. Given the limitations of the 3 GB hard drive, this soon lead to a conflict: there was no room to store any new games! I did my best to make additional room by running the disk cleaner utility, disabling unnecessary Windows features and deleting some PDF catalogues that my mother had downloaded, but there was still a constant lack of space. Armed with a lack of knowledge about computers, I went further and found a tool that promised to make more room on the hard drive. I can’t remember what it was, but it had a nice graphical user interface where the space on the drive was represented as a pie chart. To my amazement, I could slide that pie chart to make it so that 90% of the drive was free space! I went full speed ahead with it. What followed was a crash and upon rebooting I was presented with a black screen. Oops. My mother ended up taking it to a repair shop for 1200 EEK, which was a lot of money at the time. The repair shop ended up installing Windows 98 SE on it, which felt like a downgrade at the time, but in retrospect it was an improvement over Windows Me. I had no idea what I was doing at the time, but I assume that the tool I was playing with was some sort of a partition manager that had no safeguards in place to avoid shrinking and reformatting operating system partitions. Or if it did, then it made ignoring the big warning signs way too easy. Still 100% user error on my part. If only I knew that reinstalling Windows was a relatively simple operation at the time, but it took a solid 4-5 years until I did my first installation of Windows all by myself.
Oh boy, Meta released their latest llama models this weekend (I guess because they leaked, hence the rushed weekend release?), and it benchmarked quite well on LMArena. However, as Kyle Wiggers reported for TechCrunch, not all may have been on the up and up: Meta’s Benchmarks for Its

Microsoft today released updates to plug at least 121 security holes in its Windows operating systems and software, including one vulnerability that is already being exploited in the wild. Eleven of those flaws earned Microsoft's most-dire "critical" rating, meaning malware or malcontents could exploit them with little to no interaction from Windows users.
Alas, it’s time once again to revisit VUCA. Early in the pandemic, I gave two presentations about dealing with uncertainty. Institutions were struggling to respond to COVID. Many people were freaking out. But not me: I had a conceptual framework that helped me make sense of what was going on. Now that we’re again living through uncertainty, I wanted to share what I said at the time. Turns out, I never wrote about the framework itself. Let’s correct that. When contexts shift, it’s harder to act skillfully. The end of the Cold War was such a time. The tense order that emerged after World War II had ended; military leaders had to make decisions in unfamiliar territory. In response, the U.S. Army War College produced VUCA, a framework for describing unsettling contexts. It’s an acronym of their four main characteristics: Volatility: things are changing fast and often. You may understand what’s happening, but the pace of change makes it hard to respond skillfully. Uncertainty: you may understand the challenge’s basic cause and effect, but not much else. Key knowledge might be missing, but you don’t know. Complexity: the challenge has too many factors and components to grok. You have access to information — perhaps too much to connect the dots. Ambiguity: the situation is unclear, even if you have information. Causal relationships aren’t obvious, and past experiences may not apply. These four characteristics are often rendered in a 2x2 matrix. One dimension measures the degree to which we can predict the results of our actions. The other measures how much we know. For example, if we can’t predict outcomes and lack reliable knowledge, we’re in ambiguity. If we understand the situation but things are changing rapidly, we’re facing volatility. Adapted from a diagram by Nate Bennett and G. James Lemoine in the Harvard Business Review As you may expect, different characteristics call for different responses. My understanding comes from Bob Johansen’s VUCA Prime framework, which I paraphrase here: Volatility calls for vision. Draw a clear, compelling picture of where you’re heading beyond the current turmoil. Uncertainty calls for understanding. Look past headlines to the deeper forces driving change. Complexity calls for clarity. Map the system; get a grip on the entities and relationships driving change. Ambiguity calls for agility. Take the next small step; get your bearings; correct course quickly. Keeping cool isn’t easy, but it can be done. It requires some detachment. Tune out the news and take a longer-term view. Read the Stoics. Ask yourself: what’s the worst that could happen? How much is actually under your control? How can you take care of yourself, your family, and your community? Managing and structuring information flows is crucial. You need systems that surface the right information — clear, trustworthy, timely, and aligned with your goals. Information architects can help, since our focus is designing environments that support insight and skillful action. Above all, don’t panic. Nobody guaranteed this would be an easy ride. Change is the nature of things. If you panic, you’ll freeze or thrash about; either response makes things worse. Business as usual isn’t in the cards for us, but acting skillfully can be. If you found these ideas useful, check out Johansen’s Leaders Make the Future, which offers ten skills leaders can develop to thrive in a VUCA world. Much of what I know about the subject comes from this practical, well-grounded book. (Aaand… I just realized there’s a new edition — time to re-visit!)
