Lamborghini Revuelto review: perfect harmony

With the dawning of a new era of hybridization in the automotive industry, more and more manufacturers are integrating electric propulsion into their lineups. Mild-hybrid systems are well-established, and more beneficial plug-in hybrid systems keep getting better and better.

James Wan Offers a Mildly Discouraging Update on That ‘Train to Busan’ Remake

Released in 2016, Yeon Sang-ho‘s Train to Busan proved there were still plenty of fresh thrills to be mined from the zombie genre. It spawned an animated prequel and a sequel, and nobody was surprised when an American remake, to be titled The Last Train to New York, was announced. A 2023 release date made things official… almost. Obviously, The Last Train to New York—which at one point had Timo Tjahjanto (May the Devil Take You, this year’s Nobody 2) attached to direct and Gary Dauberman (It an

How much slower is random access, really?

by Sam Estep, 2025-06-23 You may know that, because your computer has different caches (L1, L2, L3...), and memory operations operate on cache lines of about 64 bytes each, you should write programs that exhibit locality to get maximum performance. L1 L1 L1 L1 L1 L1 L2 L2 L2 L2 L2 L2 L3 RAM (Disk not shown, of course.) But how well do you understand this idea? For instance, let's say you have an array of floating-point numbers, and an array of all the indices of the first array. You have a p

A Review of Aerospike Nozzles: Current Trends in Aerospace Applications

The design of rocket nozzles aims to expand the combustion gases until the exit pressure matches the ambient pressure, thereby maximizing thrust. However, ambient pressuredecreases as the rocket ascends, posing a challenge for conventional nozzles, which operate efficiently only at a specific altitude [ 30 ]. By adjusting their flow characteristics to the varying atmospheric pressure, aerospike nozzles offer a significant advantage in this regard. To quantify this impact, the thrust coefficient

Insta360 has a cheaper Flow 2 gimbal for the masses

It duplicates many of the features from the Flow 2 Pro, which launched in January. Insta360's new gimbal isn't quite "Pro," but its pricing isn't, either. The Flow 2 includes many of the features from the Flow 2 Pro while costing $50 less. The Insta360 Flow 2 ticks most of the boxes that its Pro sibling does. (The more expensive gimbal launched earlier this year.) Like that model, the Flow 2 features a built-in selfie stick and a tripod. It supports advanced subject tracking, golden ratio subj

Muvera: Making multi-vector retrieval as fast as single-vector search

Neural embedding models have become a cornerstone of modern information retrieval (IR). Given a query from a user (e.g., “How tall is Mt Everest?”), the goal of IR is to find information relevant to the query from a very large collection of data (e.g., the billions of documents, images, or videos on the Web). Embedding models transform each datapoint into a single-vector “embedding”, such that semantically similar datapoints are transformed into mathematically similar vectors. The embeddings are

Russia frees REvil hackers after sentencing

Four members of the REvil ransomware group have been released from custody despite pleading guilty to fraud and malware distribution charges. The Dzerzhinsky Court of St. Petersburg allowed Roman Muromsky, Andrei Bessonov, Mikhail Golovachuk, and Dmitry Korotaev to walk free after sentencing them to five years in prison on Monday, ruling that the gang members had spent enough time in a Russian detention center while awaiting trial. The case is unrelated to the prolific and high-profile ransomwa

Best Internet Providers in Oakland, California

AT&T Fiber is CNET's pick for the best internet provider in Oakland thanks to its extensive coverage and speeds of up to 5 gigabits.

The Internet Choice Ordinance regulation, introduced a few years ago, ensures landlords of multiunit properties can’t restrict tenants’ internet options, giving renters more flexibility to find th

Assembly Theory of Time

If the lineages are followed back beyond the origin of life on Earth to the origin of the universe, it would be logical to assume that the memory of the universe was lower in the past, which means that the universe's ability to generate objects of high Assembly is limited by its size in time. Some objects are too large in time to come into existence in intervals that are smaller than their assembly index. For complex objects such as computers to exist in our universe, many other objects had to f
