Everything I know about good system design

news.ycombinator.com Unknown 2025-08-16 07:38:46

I see a lot of bad system design advice. One classic is the LinkedIn-optimized “bet you never heard of queues” style of post, presumably aimed at people who are new to the industry. Another is the Twitter-optimized “you’re a terrible engineer if you ever store booleans in a database” clever trick. Even good system design advice can be kind of bad. I love Designing Data-Intensive Applications, but I don’t think it’s particularly useful for most system design problems engineers will run into. Wha

GPT-5 brings big improvements to Mac vibe coding

Have a Headache? These Are the Best Foods to Help Relieve It

cnet.com See Full Bio 2025-08-19 21:39:00

Headaches can be annoying and persistent, and taking aspirin or simply lying down may not always help. If that sounds like you, you may want to look at changing your plate of food for more relief. Of course, just changing what food you consume won't automatically cure headaches or migraines, but some foods may help ease them when they arrive -- in addition to hydration, exercise, sleep and stress management. Tracking those habits and symptoms over time can be easier with the right smartwatch. "

Misunderstood “photophoresis” effect could loft metal sheets to exosphere

arstechnica.com Unknown 2025-08-20 06:28:50

Most people would recognize the device in the image above, although they probably wouldn't know it by its formal name: the Crookes radiometer. As its name implies, placing the radiometer in light produces a measurable change: the blades start spinning. Unfortunately, many people misunderstand the physics of its operation (which we'll return to shortly). The actual forces that drive the blades to spin, called photophoresis, can act on a variety of structures as long as they're placed in a suffic

Researchers Harness Black Metal to Turbocharge Solar Power

gizmodo.com Gayoung Lee 2025-08-21 14:00:39

Several years ago, an optics expert developed a technique for turning shiny metals pitch black. The trick resulted in a material perfectly suited for absorbing sunlight—so much so that generators built with it produced 15 times more power than comparable devices. The team used black metal to develop a new design for solar thermoelectric generators. Known as STEGs, they can convert various types of thermal energy into electricity. However, technological limitations significantly curbed their pot

‘Are You Surprised?’: Trump Shrugs Off New Suspected Hack of Documents by Russia

President Donald Trump was asked on Wednesday about the recent hack of a computer system that holds highly sensitive federal court documents. Russia is suspected to be behind the attack, as the New York Times first reported on Tuesday. But Trump doesn’t seem to think it was a big deal, even as the president prepares to meet with Russia’s President Vladimir Putin.

Why AI Shouldn’t Replace Historians Anytime Soon

Microsoft recently released a study about the types of jobs most likely to be augmented by AI in the future. It led many people to assume those are the jobs that will soon be replaced by machines, and since “historian” ranked second highest on the list, it raised more than a few eyebrows among historians on social media.

New adhesive surface modeled on a remora works underwater

Most adhesives can’t stick to wet surfaces because water and other fluids disrupt the adhesive’s bonding mechanisms. This problem, though, has been beautifully solved by evolution in remora suckerfish, which use an adhesive disk on top of their heads to attach to animals like dolphins, sharks, and even manta rays. A team of MIT scientists has now taken a close look at these remora disks and reverse-engineered them. “Basically, we looked at nature for inspiration,” says Giovanni Traverso, a prof
