APPLE AND SPACEX LINK UP TO SUPPORT STARLINK SATELLITE NETWORK ON IPHONES

Apple has been working with SpaceX and T-Mobile US to add support for the Starlink network in its latest iPhone update. T-Mobile this week enabled a small number of iPhones as part of its beta test of the Starlink service. Users in the program have access to a new toggle switch in their iPhone cellular data settings to manage the satellite feature. T-Mobile is aiming to support the vast majority of modern smartphones when the service fully launches.

WHAT'S OAUTH2 ANYWAY?

OAuth2 is a widely used authorization framework that allows users to grant third-party applications access to their data without sharing their credentials directly. This post goes over the history and security concerns addressed by OAuth2. It then dives into the different OAuth2 flows (authorization code, implicit, client credentials, resource owner credentials, and device code), outlining their functionalities, security implications, and appropriate use cases.

'CRYPTO IS BACK': VARIOUS INVESTOR GROUPS SEE A NEED TO RAMP UP AMID US POLITICAL SHIFT

Analysts report growing institutional interest in crypto markets amid the Trump administration's policy shift, with diverse investor groups across finance, tech, and energy looking to increase their crypto exposure. Bernstein maintains a $200,000 Bitcoin price target for end-2025, citing catalysts like Trump's executive order, potential strategic digital asset reserves, and a projected $120 billion in Bitcoin ETF and corporate purchases in 2025. While institutional investors remain neutral on direct Bitcoin exposure, they show particular interest in crypto-related equities, with Robinhood seeing a 370% rise over 12 months and mining companies pivoting toward AI capabilities, leading Bernstein to maintain outperform ratings on several sector stocks including MicroStrategy, Robinhood, and Core Scientific.

DEEPSEEK CHIEF'S JOURNEY FROM MATH GEEK TO GLOBAL DISRUPTOR

China's DeepSeek is led by Liang Wenfeng, a math geek who caught the investing bug. Liang's hedge fund, High-Flyer, manages around $8 billion, making it one of China's largest quantitative funds. He has been described as a hands-on leader who sometimes sleeps in the office with colleagues as they rush to get projects done. Liang keeps a low profile and was surprised to see DeepSeek turn into a frenzy overnight. DeepSeek's sudden popularity caught the company off guard, making Liang work with his team to address the demand before taking a break for the Lunar New Year holiday in China.

Boom Superconic's XB-1 demonstrator plane went supersonic in the skies over California's Mojave Desert on its 12th test flight. It cleared Mach 1 and stayed supersonic for around four minutes, reaching Mach 1.1. This is the first time a supersonic engine has come from something other than a nation-state. Boom already has customers waiting for its technology when it matures. The company is doing some work with the US Air Force, but it remains focused on making supersonic passenger travel a reality again.

NEW GLOWING MOLECULE, INVENTED BY AI, WOULD HAVE TAKEN 500 MILLION YEARS TO EVOLVE IN NATURE, SCIENTISTS SAY

Scientists used an AI model to simulate 500 million years of molecular evolution, which resulted in the code for a previously unknown glowing protein similar to those found in jellyfish and corals. While the simulated protein only exists in computer code, the model used to create it may help in the development of new medicines. The model, called ESM3, doesn't design proteins within the usual constraints of evolution - it is a problem-solver that fills in gaps of incomplete protein code. ESM3 learns fundamental biology and then creates functional proteins outside the space explored by evolution.

COMPLETE HARDWARE + SOFTWARE SETUP FOR RUNNING DEEPSEEK-R1 LOCALLY

This thread details a $6,000 setup for running the full DeepSeek-R1 model locally. The setup requires two CPUs and 768GB of RAM across 24 RAM channels. It doesn't include a GPU, though a GPU can be added for faster generation speed. The build described in the thread can generate six to eight tokens per second, depending on the specific CPU and RAM speed purchased. A video of the build running inference is available in the thread.
