If you’ve always wanted an Italian sports sedan but assumed the price would be out of reach, there’s now a compelling opportunity in the used market. The 2023 Alfa Romeo Giulia, in its non-Quadrifoglio trims, has depreciated enough that well-equipped examples can now be found for less than $25,000. That’s a rare price point for a European performance-leaning sedan with distinct style and engaging dynamics.

I started a climate modeling project assuming I'd be dealing with "large" datasets. Then I saw the actual size: 2 terabytes. I wrote a straightforward NumPy script, hit-run, and grabbed a coffee. Bad idea. When I came back, my machine had frozen. I restarted and tried a smaller slice. Same crash. My usual workflow wasn't going to work. After some trial and error, I eventually landed on Zarr, a Python library for chunked array storage. It let me process that entire 2TB dataset on my laptop without any crashes. Here's what I learned:

The bar for a NAS can be lower than the ultra-expensive hardware it usually requires. Sometimes, it can be as simple as a hard drive or a DAS plugged into a Wi-Fi router via its USB port.

I use free apps every day, and I write about them constantly. In many cases, they’re genuinely great. Some of the most useful software on my phone and computer doesn’t cost me a cent upfront. But that doesn’t mean it’s actually free.

I spent months tasting my way through vegan meal kits and prepared meal delivery services to find the tastiest plant-based options.

This new prescription hearing aid has a special chip designed to improve hearing in noisy conditions.

A thin, watery layer coating the surface of ice is what makes it slick. Despite a great deal of theorizing over the centuries, though, it isn't entirely clear why that layer forms.

You don't need to Ernest Shackleton yourself to reap the benefits of cold plunging. A calm, controlled ice bath is key.

Q&A with David Liu, CEO of PlusAI, which is slated to go public next month, on the ongoing commercial trial of its autonomous truck driving software, and more  —  With his company set to hit the public markets in February, Liu envisions a future where most vehicles, commercial or not, are driving themselves.

In [Big Clive]’s recent grab bag of tat ordered from Chinese commerce platforms, there were two touch light control boxes that can turn any ungrounded conductive surface into a mains load dimmer control. Of course, the primary reason for the purchase was a teardown, and a teardown we got.

These unassuming little boxes are built around the Tontek TT6061A, listed as a ‘touch dimmer’, which uses a triac to control the output current. There are four levels, ranging from off to full brightness, before the next touch event turns the output off again.

With the output off, [Clive] measured 0.7 W power usage. After popping open the plastic enclosure, the circuitry turned out to largely follow the recommended application circuit from the datasheet — as can be seen in the above screenshot — with apparently a few cost optimizations, in the form of omitted diodes and a capacitor.

The problem with these devices is that they are only really suitable for dimming low-power resistive loads like incandescent lights, with LED lights likely requiring the unpopulated capacitor spot on the PCB to be populated to tweak the chip’s triac timing, among other changes. There are also the slight issues with no real concern with them radiating EMI, and the exciting possibility of getting shocked at mains voltage without at least a class-Y capacitor installed.

Perhaps using a capacitive touch controller instead that works through plastic, for example, isn’t such a crazy alternative here, especially since they’re not really much more expensive and less likely to shock you. Want to create your own triac designs? We have just the post to get you started.

Mention the INDIRECT function in an Excel forum and you'll start a fight. It's volatile, meaning it's always awake and recalculating, which can turn a fast spreadsheet into a sluggish mess. But used correctly, it's a power user's secret weapon for building dynamic, reactive dashboards.

Home Assistant is arguably the best choice for anyone looking to start a smart home, but this is especially true for power users. If you want unhindered freedom to decide how your smart home functions and you’re not afraid to get your hands dirty, there’s no better choice.

Google Sheets is hiding a massive productivity feature in plain sight: the timeline builder. It's dynamic, it's colorful, and best of all, it updates itself. So, forget the manual formatting—here's how to build your own visualized project tracker in just five minutes.
