Amazon Web Services experienced a major outage yesterday that took down numerous websites. Many sites came back online within a few hours. All AWS services returned to normal operations shortly after 6 PM ET. The outage was first reported at 3:11 AM ET. The AWS status page said it was a DNS issue with DynamoDB, a database service that underpins many AWS applications.

<strong>How Sam Altman Tied Tech's Biggest Players to OpenAI (16 minute read)</strong>

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
OpenAI CEO Sam Altman went on a dealmaking blitz to achieve his vision of securing seemingly endless computing power for his company. He played the egos of Silicon Valley's giants, resulting in a game of financial one-upmanship that has tied the fates of the world's biggest semiconductor and cloud companies to OpenAI. Vast swaths of the US economy are now betting on the success of a startup that is nowhere near turning a profit and facing a mounting list of business challenges. Investors don't seem to be bothered, as the stock prices of companies that have made deals with OpenAI have soared.

<strong>Vision Restored Using Prosthetic Retinal Implant (5 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Researchers have restored some vision to people with a loss of retinal photoreceptors using a prosthetic retinal implant. The vision restored is black and white, blurry, and has a small field of view. The implant receives signals from glasses and a camera that projects infrared images to the artificial retina. Most patients do not see better immediately - they need months of training. The researchers are in talks with the FDA about selling the device in the US.

Genome writing is humanity's next great moonshot. The Human Genome Project-write (HGP-write) and SynHG, the Synthetic Human Genome Initiative, aim to develop the technology to write DNA. DNA synthesis could transform biology, medicine, and industry. Global cooperation would ensure that the technology is used wisely and for the common good.

<strong>Claude Code is unreasonably good at building MVPs (4 minute read)</strong>

<br>

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Concerns about technical debt and quality are premature in the prototyping and validation stage. Perfect code isn't required to validate whether people want your product. What is needed is the ability to test more ideas quickly. Claude Code allows people to validate through building and testing. The ideas that survive contact with actual users are the ones worth refactoring, hardening, and scaling.

<strong>Front-end maximalism (7 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Just considering a front-end maximalist approach can lead to better designs. Doing almost everything on the front end is underrated and increasingly viable. Don't divide responsibilities between the front and back end just out of habit. It is possible to get all the modularity you need by structuring your code appropriately.

<strong>With SpaceX Behind Schedule, NASA Will Seek More Moon Lander Ideas (9 minute read)</strong>

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
NASA is looking for a Plan B to carry astronauts to the Moon's surface because SpaceX is behind schedule. It is opening bidding on a contract to build a new lunar lander. The agency wants to beat China, which is aiming to send astronauts to the Moon by 2030. President Trump wants the moon landing to occur before the end of his term. SpaceX CEO Elon Musk responded dismissively to the news, saying that SpaceX is moving at a lightning pace compared to the rest of the industry and that Starship will end up doing the whole Moon mission.

It is possible to act without prediction. Most good businesspeople don't attempt to predict the future. They instead design their lives and organizations for fast adaptation under uncertainty. You can safely ignore any essay that attempts to predict the future. Just look at what is happening right now - you'll have plenty of time to adapt.
