Recently I have come across a nice article: Many Hard Leetcode Problems are Easy Constraint Problems, and I figured, I really should learn how to use these things! What else do I really have to do? I have had use for solvers (or as they are commonly called: theorem provers) In a previous article, but then I tried to prove the things with good old algorithms. I looked at z3 at the time, but found the whole concept a bit too opaque. Now however, it seemed a bit easier to get into. To be clear, as

Arm has just unveiled its next-gen processor technologies for upcoming smartphones, which could potentially land in consumer hands as soon as the end of the year. As usual, we have new CPU and GPU parts to cover, but there are also a lot of subtle changes to the familiar formula to get our heads around this year as well. That’s hardly surprising, the landscape has changed quite rapidly in the last twelve months. Qualcomm has gone down the custom Arm-based CPU route with the Snapdragon 8 Elite,

C1 modem planned for the iPhone 17 Air is slower on some carriers

9to5mac.com Ben Lovejoy 2025-10-06 19:39:20

Apple has been working for many years on developing its own mobile data modem to replace the Qualcomm ones on which it has traditionally relied. The first of these, the C1 chip, was used in the iPhone 16e, and is also expected to be used in the upcoming iPhone 17 Air. There have so far been mixed messages on how well it compares to Qualcomm’s current chip, and a new study by Ookla provides our most detailed comparison yet … Ookla’s speed tests If you’ve ever tested your home or mobile broadba

Apple’s new C1 brings two killer features, and it’s just the start

9to5mac.com Ryan Christoffel 2026-01-16 12:49:31

Apple’s forthcoming iPhone 17 Air will come with a key component many years in the making: the C1 modem, which debuted in the iPhone 16e. The idea of a new modem may not sound very exciting, but already with this first version it’s become clear why Apple spent so long developing it. There are cost benefits to ditching Qualcomm, but also user-facing improvements. Here are two killer features Apple’s new C1 enables. #1: Battery life gains Who among us wouldn’t appreciate a little more battery li

Hands on: Spigen adds to C1 line with iMac G3-inspired Apple Watch stand

Spigen is one of my favorite Apple accessory companies because they know how to evoke nostalgia. Last year I picked up their C1 iPhone case and Magsafe wallet that themed my iPhone 16 Pro Max like the old school iMac G3 that I grew up using in school. I loved every part of that experience, and it was a great conversation starter! This year, they have added to their C1 lineup with their Apple Watch stand that isn’t just themed after the iMac G3, but looks like a tiny G3 iMac. Here is what you sho

Reverse Engineering the Microchip CLB

Microchip added a very cool peripheral called the Configurable Logic Block (CLB) to there new PIC16F13145 microcontroller family. It’s essentially a small FPGA (32 LUTs) that can connect to the internals of the chip. However, they don’t document how to configure it yourself, only referring you to their online configurator tool that submits jobs to an API that places and routes to LUTs. The [CLB] Interface does not appear as an SFR in the Register Map and is not directly user-accessible; it is

Apple’s C1 is coming to this product next, and skipping the rest

When Apple launched its iPhone 16e earlier this year, it included a brand new component: the C1 modem. But more recent devices like the M3 iPad Air and A16 iPad haven’t included it. Here’s where the C1 will appear next, and which products are not expected to get it. Why the C1 modem was worth the wait For many years, Apple has been working to develop its own cellular modem tech. Absent that tech being ready, the company has had to rely on Qualcomm to supply 5G modems for its devices. While Qu
