Dave Cutler is a seminal figure in computer science, renowned for his contributions to operating systems. Born in 1942, he played pivotal roles in the development of several OSes, most notably VMS for Digital Equipment Corporation (DEC) and Windows NT for Microsoft. Cutler’s design principles emphasize performance, reliability, and scalability. His work on Windows NT laid the foundation for many subsequent Windows versions, solidifying its place in enterprise and personal computing. A stickler for detail and a rigorous engineer, Cutler’s influence is evident in modern OS design and architecture. He’s a recipient of the Computer History Museum’s Fellow Award for his unparalleled contributions.

Interpolation and digital cropping are two techniques which are commonly used by marketing folk to embellish the true specifications of a device. Using digital cropping a fictitious zoom level can be listed among the bullet points, and with frame interpolation the number of frames per second (FPS) recorded by the sensor is artificially padded. This latter point is something which [Yuri D’Elia] came across with a recently purchased smartphone that lists a 960 FPS recording rate at 720p. A closer look reveals that this is not quite the case.
The smartphone in question is the Motorola Edge 30 Fusion, which is claimed to support 240 and 960 FPS framerates at 720p, yet the 50 MP OmniVision OV50A sensor in the rear camera is reported as only supporting up to 480 FPS at 720p. To conclusively prove that the Motorola phone wasn’t somehow unlocking an unreported feature in this sensor, [Yuri] set up an experiment using three LEDs, each of which was configured to blink at either 120, 240 or 480 Hz in a side-by-side configuration.
As [Yuri] explains in the blog post, each of these blinking frequencies would result in a specific pattern in the captured video, allowing one to determine whether the actual captured framerate was equal to, less than or higher than the LED’s frequency. Perhaps most disappointingly about the results is that this smartphone didn’t even manage to hit the 480 FPS supported by the OV50A sensor, and instead pegged out at a pedestrian 240 FPS. Chalk another one up for the marketing department.

Reddit ignited a war this year. Dramatic changes in API access pricing (from free to unaffordable) was one of its most polarizing moves ever. It resulted in apps beloved by long-time Reddit users, including moderators and people with accessibility needs, closing shop. Community trust was sacrificed, too. Disgusted with Reddit for how it handled third-party apps, abruptly ushered in pricing changes, and treated moderators who protested, numerous valuable, knowledgeable users quit the platform.
Originally, Reddit framed its API pricing changes as a way to prevent generative AI companies from using Reddit data to train large language models (LLMs) without Reddit getting anything in return. With Reddit no longer dealing with small third-party developers—all of which are now either paying Reddit or getting some sort of exemption—Reddit is reportedly taking the fight to where it should have been focused the entire time: generative AI firms.
On Friday, The Washington Post, as spotted by The Verge, said Reddit "has met with top generative AI companies about being paid for its data," citing an anonymous source.

On the surface, a programmable logic controller (PLC) might seem like nothing more than a generic microcontroller, perhaps outfitted to operate in industrial settings with things like high temperatures or harsh vibrations. While this is true to some extent, PLCs also have an international standard for their architecture and programming languages. This standard is maintained by the International Electrotechnical Commission, making it so that any device built under these specifications will be recognizable to control engineers and maintenance personnel worldwide. And, if you use this standard when working with certain Arduinos, this common platform can become a standard-compliant PLC as well.
The IDE itself supports programming ladder diagrams, functional block diagrams, and other programming systems covered under the IEC 61131-3 standard. Not only that, it allows the combination of these types of PLC programming with Arduino sketches. The system offers many of the perks of PLC programming alongside the familiar Arduino platform, and supports a number of protocols as well including CANOpen, Modbus RTU, and Modbus TCP. It can also be used for monitoring a PLC system, essentially adding IoT capabilities to existing systems, enabling continuous monitoring, debugging, and program updates.
While not every Arduino is a great platform to build a PLC around, there are a few available for those looking for a system a little less proprietary and a little more user-friendly than typical PLC systems tend to be. There’s a reason that PLCs are built around an international standard and generally have certain hardware in mind to run it, though, and this comparison of a Raspberry Pi with an off-the-shelf PLC goes into detail about why certain components aren’t good choices for PLCs.
