The Apple Watch Ultra 4, which launched with a $799 price tag, is now available on Amazon for $699.99, a $99 reduction. This marks the first significant discount since the watch's release and undercuts the previous 2024 low of $774.
Amazon is selling the Apple Watch Ultra 3 (49mm GPS + Cellular, titanium case, Light Blue Alpine Loop, size L) for $649, down from its $799 list price, a 19% discount. The model carries a 4.7-star Amazon rating and includes features like dual-frequency GPS, satellite Emergency SOS, a sapphire crystal display, and up to 42 hours of battery life.
Apple is preparing to unveil redesigned MacBook Pros at an Oct. 28 'Pro and tell' event in LA, featuring OLED displays, touch support, a lighter build, and M5 Pro/M5 Max chips. Reports have circulated about possible cellular connectivity using Apple's in-house modems, though it remains unconfirmed whether this generation will include it.
A comparison explains that eSIM and physical SIM cards offer identical network reception and data speeds, with the key distinction being how service is activated and transferred. eSIMs let users activate plans via app, QR code, or settings, store multiple profiles, and set up travel plans in advance without hunting for a local SIM vendor. Physical SIMs remain simpler to remove and swap manually, though eSIM activation requires compatible, unlocked devices.
Rule 30 is one of 256 simple cellular automata built from a single logic rule applied repeatedly to rows of black and white squares, first studied systematically by Stephen Wolfram in the early 1980s. Despite its simplicity, the automaton's central column of cells has never been proven to either repeat or avoid repeating, even though statistical tests show it behaving like a fair coin toss. The pattern was long used to generate random integers in Mathematica and has been applied decoratively, including on buildings at Cambridge.
Apple has posted a job opening for a 6G Cellular Modem Systems Engineer, offering a base salary between $175,000 and $308,500 plus stock and other benefits, according to a listing spotted by MacRumors. The role calls for defining requirements and algorithms for next-generation modems, at least 10 years of cellular industry experience, and familiarity with 3GPP standards, MATLAB, C/C++ or Python, as well as generative AI tools to speed up engineering workflows.
A new report suggests the Exynos version of the upcoming Galaxy S27 could receive improved cellular modem performance and efficiency, narrowing the historical gap with the Snapdragon variant. Samsung typically splits Galaxy flagship production between its own Exynos chips and Qualcomm's Snapdragon processors depending on region.
A technical write-up details how NetHack generates its Gnomish Mines levels: 40% of cells are randomly set as floor, then four passes of cellular automata rules (based on counting floor neighbors) reshape the grid into organic cave layouts, with a final step adding corridors to connect any isolated caves. The author breaks down each pass's rule set, noting that the first pass is applied without buffering while the remaining three use buffered updates across the whole grid.
Rubedo Life Sciences, a Mountain View biotech, presented early data at the Aging Research and Drug Discovery meeting showing its experimental topical cream reduced skin biological age by about two years on average in an 11-person trial. The cream targets senescent 'zombie' skin cells in patients with atopic dermatitis, and an independent analysis by Mitra Bio found reduced inflammation markers and a 10 percent rise in elasticity-related collagen after four weeks of use.
Apple's iOS includes a Low Data Mode, found under Settings > Cellular > Data Mode, that reduces streaming quality, pauses automatic updates and backups, and limits background refresh to conserve mobile data. Users can also disable Background App Refresh selectively through Settings > General, or block individual apps from using cellular data entirely via the Cellular settings menu.
Weeks after its launch, the Apple Watch Ultra 4 is being sold for $700, down from its $799 list price, with the discount applying to the black titanium model paired with a burgundy trail loop. CNET notes pricing varies by color and band combination and can change without notice.
Amazon is selling the 46mm cellular Apple Watch Series 12 in a night blue ceramic case with navy sport band for $900, down from $949, on the last day of its Prime Day sale. The aluminum 46mm cellular version is also discounted by $49, to $500. Apple says the Series 12 includes new heart-rate and health sensors, a Readiness app, and Siri support.
