Vortex's Wireless Take On the Model M Keyboard: Cover Band Or New Legend?

3 weeks 1 day ago
IBM's legendary Model M keyboard was sturdy and solid. But "What would happen if you took the classic layout and look of the Model M and rebuilt it with modern mechanical guts?" asks long-time Slashdot reader uninet. Writing for the long-running tech blog Open for Business , they review a new wireless keyboard from Vortex that was clearly inspired by the Model M: The result is a unique keyboard with one foot in two different decades... Let's call it the Vortex M for simplicity's sake. I first became aware of it on a Facebook ad and was immediately fascinated. It looked so close to the original Model M, I wondered if someone else had gotten access to an original mold and was trying Unicomp's game. No, they've just managed to copy the aesthetic to a nearly uncanny level... The Vortex M eschews the normal eye candy we expect on modern keyboards and attempts the closest duplication of IBM's staid early PC design sensibility I can imagine. Off-white, rugged and absolutely no frills of lighting. If you're looking for cutesy, forget it. The keyboard's casing has the same highly textured plastic that looks and feels instantly familiar to anyone who spent too many hours interacting with early PCs. Model M to a tee. The keycaps likewise look the part... The Vortex M looks like a Model M. Its build quality feels like a Model M. But one key press and it becomes clear this is a different beast. Underneath the Model M-styled skin, Vortex's keyboard is a very modern design — everything the Unicomp is not. For our test, Vortex provided a keyboard with Cherry MX Blues, the classic clicky option the company and I both thought would best match up against Model M's buckling springs... Vortex's product configurator offers a variety of common and less common Cherry and Gateron options, if you want to get a different sort of feel in lieu of the clicky I tested. This is possible with an MX switch-style keyboard and impossible with buckling springs with their one option of bold clicky. Not only can this be done when ordering, but also later on, thanks to hot swap switches that allow changes without soldering. Following the modern premium board theme, Vortex paired high end switches with a gasket mount and foam padding. The combination provides a solid feeling, sound dampened typing experience. Ironically, though, for a keyboard that apes the design of perhaps the loudest keyboard on the market today, the Vortex M is (relatively) quiet even with the clicky Blues on tap... The review's highlights: "The keyboard is exquisitely crafted to look like the IBM original... " "The Vortex M supports connecting to three different devices via Bluetooth, along with a 2.4 GHz receiver and a USB Type-C wired connection. " There's a full complement of media hot keys — "including an emoji key ala recent Macs. " "For repetitive tasks, the keyboard is programmable with macros... And unlike Unicomp's boards, Vortex's can switch between PC and Mac layouts with the press of a hotkey." The keyboard uses AA batteries rather than having a built-in rechargeable battery The keyboard ultimately gave the reviewer some cognitive dissonance. "How am I typing on a Model M and not making a racket...?" "Pricing varies based on options, but as tested, it clocked in at $154. That's the low end of the 'premium' market and this is an exceptional board for that price."

The Toughest Programming Question for High School Students on This Year's CS Exam: Arrays

3 weeks 1 day ago
America's nonprofit College Board lets high school students take college-level classes — including a computer programming course that culminates with a 90-minute test. But students did better on questions about If-Then statements than they did on questions about arrays, according to the head of the program. Long-time Slashdot reader theodp explains: Students exhibited "strong performance on primitive types, Boolean expressions, and If statements; 44% of students earned 7-8 of these 8 points," says program head Trevor Packard. But students were challenged by "questions on Arrays, ArrayLists, and 2D Arrays; 17% of students earned 11-12 of these 12 points." "The most challenging AP Computer Science A free-response question was #4, the 2D array number puzzle; 19% of students earned 8-9 of the 9 points possible." You can see that question here. ("You will write the constructor and one method of the SumOrSameGame class... Array elements are initialized with random integers between 1 and 9, inclusive, each with an equal chance of being assigned to each element of puzzle...") Although to be fair, it was the last question on the test — appearing on page 16 — so maybe some students just didn't get to it. theodp shares a sample Java solution and one in Excel VBA solution (which includes a visual presentation). There's tests in 38 subjects — but CS and Statistics are the subjects where the highest number of students earned the test's lowest-possible score (1 out of 5). That end of the graph also includes notoriously difficult subjects like Latin, Japanese Language, and Physics. There's also a table showing scores for the last 23 years, with fewer than 67% of students achieving a passing grade (3+) for the first 11 years. But in 2013 and 2017, more than 67% of students achieved that passsing grade, and the percentage has stayed above that line ever since (except for 2021), vascillating between 67% and 70.4%. 2018: 67.8% 2019: 69.6% 2020: 70.4% 2021: 65.1% 2022: 67.6% 2023: 68.0% 2024: 67.2% 2025: 67.0%
