OpenAI will purchase $300 billion in computing power from Oracle over roughly five years. The deal, which far outstrips OpenAI's current revenue, is one of the largest cloud contracts ever signed. It will require 4.5 gigawatts of power capacity, the amount consumed by roughly four million homes. Oracle's share price recently surged, increasing its Chairman Larry Ellison's wealth by more than $100 billion. OpenAI and Oracle's contract will start in 2027.

Elon Musk said during a podcast on Tuesday night that Starlink could become a mobile carrier. SpaceX recently reached a $17 billion deal to buy radio spectrum from EchoStar, BoostMobile's parent company. The deal will give SpaceX access to several 1.9GHz and 2GHz bands in the US. Some hardware changes may be required as these frequencies are not supported in current phones.

SpaceX is readying a bigger version of Starship capable of carrying more than 100 tons of payload to orbit. Its current iteration of the vehicle has a capacity of about 35 tons. SpaceX is aiming to demonstrate full reusability for Starship next year.

Construction robots are revolutionizing the industry by printing floor plans directly onto concrete slabs, offering unparalleled precision and efficiency. Traditional methods of laying out floor plans are labor-intensive and error-prone. New robots use Building Information Modeling data to autonomously print accurate floor plans, eliminating the need for manual measurements and chalk lines. A video showing one of the robots in action is available in the article.

It's possible to beat the best sort implementations with domain-specific knowledge, careful benchmarking, and an understanding of CPU micro-architectures. However, assumptions will become invalid and mistakes may creep in silently. Good sort implementations can be surprisingly fast even without prior domain knowledge. Developers should think twice about replacing high-quality sort implementations with something home-grown.

Automation is a tool, not a goal. We should never automate something for the sake of it. Automation is great for self-documenting, and it can help fight human error, but it should be wielded with purpose. It shouldn't be the default regardless of its effectiveness at being fit for any particular purpose.

TikTok is primed to disrupt Google. New research shows that there is a closing gap between Google and TikTok's search engines, especially among Gen Z. Many people are turning to TikTok while searching for specific categories like fashion and beauty advice, cooking, entertainment, and DIY. If Google continues down its current path, we could be headed into a fragmented search world where ChatGPT handles complex queries, TikTok serves users who want audio-visual results, and Google plays the middle while hanging on to its market share.

Oracle recently revealed in its fiscal first-quarter report that remaining performance obligations more than tripled from three months ago to $455 billion. The company has even more multibillion-dollar deals in the pipeline that could take that number past half a trillion. The sharp rise in revenue was fueled by demand for artificial-intelligence computing. Oracle now expects its cloud infrastructure revenue to hit $114 billion in the 2029 fiscal year.
