Abstraction boundaries are optimization boundaries

news.ycombinator.com Unknown 2025-08-23 10:12:10

Abstraction boundaries are optimization boundaries The N+1 query problem occurs when your application code sends one SQL query per element in a collection. The N queries are redundant; since all of the data is in the database already, a single query should be enough. This problem is usually caused by a leaky abstraction; the ORM, or whatever database abstraction you are using, can’t anticipate that it would need to send N queries, so it can’t automatically optimize this down to a single query.

cnbc.com Annie Palmer 2025-08-26 01:01:07

"But there's going to be other jobs." Even as AI eliminates the need for some roles, Amazon will continue to hi

Ask HN: 80s electronics book club; anyone remember this illustrator?

In the early 80's in the US, a popular DIY electronics magazine had a book of the month club that I loved. Most were small and leather bound hardback with topics like: make your own hydrophone; augmented reality (required a full room and a boom arm, sadly); an LCD model rocket launcher ignition; computer vision; lots and lots of robots.

This Survey Asked Neuroscientists If Memories Can Be Extracted From the Dead. Here’s What They Said

gizmodo.com Natalia Mesa 2025-08-26 13:20:54

The allure and terror of transferring your consciousness to a computer has long been fodder for cyberpunk novels and billionaire-backed immortality startups. But a substantial chunk of neuroscientists think it might be possible to extract memories from a preserved brain and store those memories inside a computer, according to a new study. The study, published in the journal PLOS One, suggests that most neuroscientists believe that memory has a physical basis and, on average, give a 40% probabil
