This tiny Italian town boasts sweeping countryside views - but it's a 43cm-wide alley that's stopping visitors in their tracks.

Python is (in)famous for its "batteries included" approach to a standard library, but it's not that notable that it has plenty of standard data structures, like dicts. Nor is in surprising that dicts have all sorts of useful methods, like pop, which removes a key from the dict and returns its value.

Because you're here, reading this site, you'll also be unsurprised that this doesn't stop developers from re-implementing that built-in function, badly. Karen sends us this:

def parse_message(message): def pop(key): if key in data: result = data[key] del data[key] return result return '' data = json.loads(message) some_value = pop("some_key") # <snip>...multiple uses of pop()...</snip>

Here, they create an inner method, and they exploit variable hoisting. While pop appears in the code before data is declared, all variable declarations are "hoisted" to the top. When pop references data, it's getting that from the enclosing scope. Which while this isn't a global variable, it's still letting a variable cross between two scopes, which is always messy.

Also, this pop returns a default value, which is also something the built-in method can do. It's just the built-in version requires you to explicitly pass the value, e.g.: some_value = data.pop("some_key", "")

Karen briefly wondered if this was a result of the Python 2 to 3 conversion, but no, pop has been part of dict for a long time. I wondered if this was just an exercise in code golf, writing a shorthand function, but even then- you could just wrap the built-in pop with your shorthand version (not that I'd recommend such a thing). No, I think the developer responsible simply didn't know the function was there, and just reimplemented a built-in method badly, as so often happens.

As the Mobile World Conference begins in Spain, Lenovo brought a new attachable accessory for their laptops — an AI agent. CNET reports: The little circular module perches on the top of your Lenovo laptop display, attached via the magnetic Magic Bay on the rear. The module is home to an adorable animated companion called Tiko, who you can interact with via text or voice... [I]t can start and stop your music, open a web page for you or answer a question. You can also interact with it by using emoji. Give it a book emoji, for example, and it will pop on its glasses and sit reading with you while you work... The company wants to sell the Magic Bay accessory later this year — although it doesn't know exactly when, or how much it will cost. It even comes with a timer (for working in Pomodoro-style intervals) — but Lenovo has also created another "concept" AI companion that CNET describes as "a kind of stationary tabletop robot, not dissimilar to the Pixar lamp, but with an orb for a head." With a combination of cameras, microphones and projectors, the AI Workmate can undertake a variety of tasks, including helping you generate and display presentations or turn your written work or art into a digital asset... It's robotic head swivelled around and projected the slides onto the wall next to me. Lenovo created a video to show this "next-generation AI work companion" — with animated eyes — "designed to transform how modern professionals interact with their workspace." It bridges the physical and digital worlds — capturing handwritten notes, recognizing gestures, summarizing tasks, and proactively helping you stay ahead of your day. The moment you sit down, Lenovo AI Workmate greets you, surfaces priority tasks, and keeps your work organized without switching apps or losing context. From turning sketches into presentations to projecting information for instant collaboration, [it] brings on-device AI intelligence directly to your desk — secure, responsive, and always ready... It's not just software. It's a smarter way to work. It looks like Lenovo once considered naming it "AI Sphere" (since that name still appears in its description on YouTube). Lenovo also showed another "concept" laptop idea that PC Magazine called "futuristic": The ThinkBook Modular AI PC looks like a traditional laptop at first glance, but a second, removable screen fastens onto the lid. You can swap that screen onto the keyboard deck (in place of the keyboard, which can then be used wirelessly), or use it alongside the laptop as a portable monitor, attached via an included cable.... While Lenovo is still working on this device, and it's very much in the concept phase, it feels like one of its best-thought-out prototypes, one likely to make it to store shelves at some point. Another "concept" laptop is Lenovo's Yoga Book Pro 3D Concept, ofering directional backlight and eye-tracking technology for the illusion of 3D (playing slightly different images to each of your eyes). It offers gesture control for 3D models, two OLED displays, and some magical "snap-on pads" which, when laid on the display — make the GUI appear on the screen for a new control menu to "provide quick-access shortcuts for adjusting lighting, viewing angle, and tone".
