TESLA BEGINS LIMITED ROBOTAXI SERVICE IN AUSTIN

Tesla began limited operations of its self-driving taxi service yesterday in Austin, Texas. The service is only available to 'Early Access' riders and the vehicles are confined to certain streets. Tesla employees will be riding in the front passenger seats and the vehicles may not operate in bad weather. Tesla's stock market valuation rests largely on promises that the company will be able to use artificial intelligence to allow its vehicles to drive autonomously pretty much anywhere there are roads - the Austin project will provide the first indications of whether Tesla's technology can match its ambitions.

SCALING OUR OBSERVABILITY PLATFORM BEYOND 100 PETABYTES BY EMBRACING WIDE EVENTS AND REPLACING OTEL

ClickHouse scaled its internal observability platform, LogHouse, to over 100 petabytes by developing SysEx, a specialized system for ClickHouse-to-ClickHouse data transfers. SysEx, unlike OTel, preserves native ClickHouse types and removes intermediate conversions, resulting in a 20x increase in event volume handled with significantly less CPU usage. They use HyperDX, a ClickHouse-native UI, for seamless data exploration, correlation, and root-cause analysis, while still using Grafana for existing dashboards.

TEXAS SIGNS STRATEGIC BITCOIN RESERVE BILL INTO LAW

Texas became the third state to establish a strategic Bitcoin reserve after Governor Greg Abbott signed SB 21 into law, creating a stand-alone, publicly funded fund managed by the Texas Comptroller of Public Accounts. The companion HB 4488 shields the reserve from periodic treasury fund-sweeps and ensures its legal existence even if no BTC is purchased by next summer. Industry observers, including the Texas Blockchain Council, anticipate the state investing tens of millions of dollars into the fund.

PSYCHE KEEPS ITS DATE WITH AN ASTEROID, BUT NOW IT'S RUNNING IN BACKUP MODE

The NASA Psyche spacecraft launched in October 2023 and proceeded normally until April 1 this year, when it detected a drop in pressure inside the line that feeds xenon fuel to its four thrusters. The craft reacted to the pressure signature by powering off the thrusters - this will have no effect on the mission's scheduled arrival at asteroid Psyche in August 2029. The spacecraft recently switched to its backup fuel line and resumed full thruster operations. The next waypoint on Psyche's voyage will be a flyby of Mars in May 2026.

MIT STUDENT PRINTS AI POLYMER MASKS TO RESTORE PAINTINGS IN HOURS

MIT graduate student Alex Kachkine developed a technique that uses AI-generated polymer films to physically restore damaged paintings in hours. It works by printing a transparent 'mask' containing thousands of precisely color-matched regions that conservators apply directly to an original artwork. These masks can be removed whenever needed, so it's a reversible process. Using the technique creates a digital record of what mask was used, so future conservators will have an extremely clear understanding of what was done to every artwork.

HOW TO VIBE CODE AS A SENIOR ENGINEER

Vibe coding is a new way of building software where you let the AI models do most of the work. Users write prompts, sketch out a plan, and let the model take over. This allows users to build features in hours, but it requires some experience to wield. This article provides some tips on how to vibe code for people who know what they're doing. It covers how to write a good prompt, what AI is good and bad at, the required tools for vibe coding, and more.
