Last year, entrepreneurs, investors and married couple Dave and Brit Morin teamed up with James Higa, who was a senior director at Apple for nearly a dozen years, and Tonal cofounder Nate Bosshard, to create a new venture firm called Offline Ventures that, very notably, counts Apple as an anchor investor. The idea, in part, is to use their collective interest in mental health and hardware to help inform Apple’s road map, though the team is looking at much, much more, and is even in the process of incubating some startups. We talked recently with the Morins — who each logged some time at Apple early in their careers — to find out more in a conversation that’s been excerpted below and edited lightly for length.

Asa Forsell Contributor Share on Twitter Asa Forsell is a senior product manager for automotive at The Qt Company . Matt Murphy, the CEO of U.S. chipmaker Marvell Technology, predicted in October that the semiconductor shortage will extend into 2022 and beyond . The shortage is already having a huge impact across the world, with German carmaker Opel announcing the pause of some of its operations until the start of next year . And this is far from an isolated incident — the Society of Motor Manufacturers and Traders recently revealed that the number of new cars registered in the U.K. in September was the lowest since 1998 . Across the world, automotive manufacturers are struggling with the semiconductor shortage, unable to build and sell enough cars to meet demand. The impact, however, is even broader. Having seen a surge in demand through the pandemic, consumer electronics are also starting to be affected by the semiconductor shortage, with research suggesting that smart

Adam Selipsky gave his first AWS re:Invent keynote this morning since taking over as CEO from Andy Jassy earlier this year. He had big shoes to fill, but it’s not as though Selipsky was a complete stranger to the AWS team. In fact, he had been at the division since its earliest days, helping Jassy to build it into a substantial business, before leaving in 2016 to become CEO at Tableau. He began the day with a history lesson, and he didn’t need to count on others to feed the background to him, given he had been there when they opened their doors in Seattle all those years ago, a pig-in-a-poke of an idea to sell web services. As Selipsky told it when he presented the cloud infrastructure concept to early potential customers, they didn’t quite get it. “What does this have to do with selling books?” he was continually asked. While he didn’t share the answer he gave, I would speculate that it had nothing to with it, and it had everything to with it. Years ago, at a presentation with A

On-demand shuttle and software company Via has raised another $130 million, capital that has pushed its valuation to about $3.3 billion as demand from cities to update its legacy transit systems rises. The round was led by Janus Henderson with participation from funds and accounts managed by BlackRock, ION Crossover Partners, Koch Disruptive Technologies and existing investor Exor. To date, the company has raised $800 million. Via, which today employs about 950 people, has two sides to its business. The company operates consumer-facing shuttles in Washington, D.C. and New York. Its underlying software platform, which it sells to cities, transportation authorities, school districts and universities to deploy their own shuttles, is not only the core of its business; it has become the primary driver of growth. Co-founder and CEO Daniel Ramot previously told TechCrunch that there was was little interest from cities in the software-as-a-service platform when the company first launched i

At AWS’s re:Invent conference this morning, the company announced AWS IoT TwinMaker , a new service that makes it easy to create and use digital twins of real-world systems . For context, digital twins are virtual representations of things like buildings, factories, production lines, and equipment that are regularly updated with real-world data to mimic the behavior of the systems they represent. The company outlines that with this new service, users can create digital twins by connecting data from sources like video feeds and applications without having to move the data into a single repository. “You can use built-in data connectors for the following AWS services: AWS IoT SiteWise for equipment and time-series sensor data; Amazon Kinesis Video Streams for video data; and Amazon Simple Storage Service (S3) for storage of visual resources (for example, CAD files) and data from business applications. AWS IoT TwinMaker also provides a framework for you to create your own data connecto

Facebook parent company Meta is losing its top crypto executive later this year. David Marcus who leads crypto unit Novi and previously helmed the company’s Messenger unit, announced Tuesday that he will be leaving the company later this year. Marcus joined Facebook in 2014.

The sensitive fern—named due to its sensitivity to drought and frost—is a widespread species found throughout eastern North America and eastern Asia. It is a dimorphic plant because it has two distinct types of leaves—one for photosynthesis and one for reproduction. While most fern species in temperate regions produce and disperse their spores in the summer, the sensitive fern has an atypical timing of spore dispersal. In the early summer they produce heavily modified spore-bearing fronds (or leaves) with leaflets tightly enveloping their sporangia and spores. These fronds deteriorate with age, yet continue to persist above ground during the winter as dead mature structures. In the early spring their leaflets open to disperse spores. While the timing of spore dispersal has been observed for over 120 years, the structural mechanisms driving this phenology have remained elusive. from Phys.org - latest science and technology news stories https://ift.tt/3I51Ae9

Well, so much for a relaxed post-holiday week on Monday. News broke this morning that Twitter CEO Jack Dorsey is stepping down from the company entirely . The company’s CTO, Parag Agrawal , will be taking over at the helm. Saleforce exec Bret Taylor will take over as board chairman. So, Amanda and Natasha and Alex jumped into onto the mics — and, ironically, a Twitter space — to riff on all things Jack and future of Twitter. From the show: Crypto and the CTO, what can we read from the tea leaves? Jack’s dual role, and its detractors. The fact that Twitter’s product work has been  great lately, which we don’t want to stop. When is a good time to leave a company, is it on the up and up or when things are quiet? And, finally, Jack’s somewhat biting words regarding founder-led companies, which are, frankly, a bit at odds with his own behavior until now. The show is back on Wednesday, unless some other major CEO resigns. Equity drops every Monday at 7:00 a.m.

In 2019, AWS launched Braket , its quantum computing service that makes hardware and software tools from its partners Rigetti, IonQ and D-Wave available in its cloud. Given how quickly quantum computing is moving ahead, it’s maybe no surprise that a lot has changed since then. Among other things, hybrid algorithms that use classical computers to optimize quantum algorithms — a process similar to training machine learning models — have become a standard tool for developers. Today, AWS announced improved support for running these hybrid algorithms on Braket. Previously, to run these algorithms, developers would have to set up and manage the infrastructure to run the optimization algorithms on classical machines and then manage the integration with the quantum computing hardware, in addition to the monitoring and visualization tools for analyzing the results.

A few years back, my former colleagues and I at SiriusDecisions introduced what we called the Intent Data Framework (IDF).

Already, it’s clear we left something out of the IDF and even BSF: product-led growth. Signal substitution syndrome Both versions of the framework were attempts to address a misunderstanding that was, and still is, so rampant in B2B that I have a name for it — signal substitution syndrome.

Controversial facial recognition company Clearview AI is facing a potential fine in the UK. It has also been handed a provisional notice to stop further processing of UK citizens’ data and to delete any data it already holds as a result of what the Information Commissioner’s Office (ICO) described as “alleged serious breaches” of national data protection law. The ICO has been looking into the tech company — which sells AI-powered identity matching to law enforcement and other paying customers via a facial recognition platform that it trained covertly on photos harvested from Internet sources (like social media platforms) — in a joint investigation with the Australian Information Commissioner (OAIC). The OAIC already, earlier this month , issued an order to Clearview to delete data after finding it broke national laws down under. So the ICO has been the laggard of the two regulators. But today it issued the notification of a provisional intention to fine Clearview over £17 million
