There's the easy way... Published: 2024-11-17 | Origin: /r/programming The content discusses a tech project involving Python and Electronic Design Automation, focusing on an algorithm to find the longest sequence of integers from input data. The author critiques a previously suggested solution that couldn't achieve O(n) time complexity due to its reliance on sorting. They propose using Python's sets for O(1) lookup times and suggest a strategy for forming and extending integer ranges by tracking the longest range found. The approach involves checking for integers that could extend existing ranges and using a dictionary to manage these ranges and |
Reverse Engineering iOS 18 Inactivity Reboot Published: 2024-11-17 | Origin: Hacker News The content explains the differences between the "Before First Unlock" (BFU) and "After First Unlock" (AFU) states on an iPhone.

How AWS Lambda Supports Container Images up to 10 GiB in Size Published: 2024-11-17 | Origin: /r/programming Function-as-a-Service (FaaS) has significantly transformed software development over the last decade by allowing engineers to focus on code without worrying about infrastructure management. AWS Lambda, a leading FaaS platform, facilitates on-demand loading of large container images (up to 10 GiB), maintaining rapid scalability and low startup times. Traditionally, Lambda functions were restricted to 250MB code archives, limiting data movement and cold start times. However, the new capability to handle larger container images presents challenges in data |

Perry aims to expand Motion's functionality, improve support and |
Nash equilibria in Ballmer's binary-search interview game Published: 2024-11-17 | Origin: Hacker News Arthur O’Dwyer discusses a puzzle presented by Steve Ballmer, which involves guessing a number between 1 and 100 with diminishing payouts based on the number of guesses. The goal is to determine the expected value of playing this guessing game assuming Ballmer chooses his secret number uniformly at random. He notes that using a binary search strategy seems logical and results in an expected value of approximately $952. However, if Ballmer is aware that the player will utilize binary search, he will avoid certain |
