UUIDv47: Store UUIDv7 in DB, emit UUIDv4 outside (SipHash-masked timestamp)

news.ycombinator.com Unknown 2025-09-28 00:02:29

UUIDv47 - UUIDv7-in / UUIDv4-out (SipHash-masked timestamp) uuidv47 lets you store sortable UUIDv7 in your database while emitting a UUIDv4-looking façade at your API boundary. It does this by XOR-masking only the UUIDv7 timestamp field with a keyed SipHash-2-4 stream tied to the UUID’s own random bits.

How to Motivate Yourself to Do a Thing You Don't Want to Do

news.ycombinator.com Unknown 2025-09-28 01:25:24

We have an air bike in our basement. If you are unfamiliar with air bikes, they are similar to stationary bikes with foot pedals but also have handles you push and pull with your arms. It uses air resistance, so the harder you pedal and move your arms, the higher the resistance. It’s also known as an assault bike. 😬 Which is apt, because it’s a butt-kicker of a workout. I use it about once a week, more frequently in the winter when it’s too cold to run, and less often in the summer when I can

Nvidia just can’t seem to catch a break. After beating a ban on China sales imposed by the Trump administration, the tech giant is now facing a ban on its products by Chinese regulators. Chinese internet regulator Cyberspace Administration of China (CAC) ordered top Chinese tech companies like Bytedance and Alibaba to end their testing and orders of Nvidia’s RTX Pro 6000D chips, the Financial Times reported on Wednesday citing people with knowledge of the matter.

Unprecedented ‘Einstein Cross’ Reveals Fifth Ghost Image and a Dark Matter Surprise

gizmodo.com Gayoung Lee 2025-09-28 01:30:14

When gravity—an invisible yet ubiquitous force—bends and distorts light from distant galaxies, Earthbound observers get a rare glimpse of elusive cosmic phenomena. And the weirder the glitch, the more insightful the finding, as a team of astronomers recently discovered. These glitches are formally referred to as Einstein Crosses. As light from a distant galaxy travels toward our observatories, the gravitational force of galaxies closer to us bends that light, creating an image of four bright do

A New Island Has Popped Up in Alaska

gizmodo.com Ellyn Lapointe 2025-09-28 01:50:04

Glaciers along the coastal plain of southeastern Alaska are rapidly retreating, spilling meltwater into expanding proglacial lakes. One such lake—fed by the receding Alsek Glacier—has grown so much that it transformed a small mountain into a new island. The Alsek Glacier once enveloped this rocky mound—known as Prow Knob—near its terminus. Over the past 40 years, both of the glacier’s arms have retreated more than 3 miles (5 kilometers), creating Alsek Lake. Landsat images captured in 1984 and

Inside Trumpworld’s Reality Distortion Field

Before a suspect was even in custody, Trumpworld was on a wartime footing. Charlie Kirk had been fatally shot. Graphic video of the assassination hit terminal velocity online. Several sources of mine were close friends of Kirk, and when I spoke to them last week, it was clear this incident had changed the level of aggression with which they were willing to pursue a crackdown on their boss’s perceived enemies. “I think we want to confront violent left wing rhetoric.
