That boolean should probably be something else

news.ycombinator.com Unknown 2025-10-28 18:31:15

Monday, June 30, 2025 One of the first types we learn about is the boolean. It's pretty natural to use, because boolean logic underpins much of modern computing. And yet, it's one of the types we should probably be using a lot less of. In almost every single instance when you use a boolean, it should be something else. The trick is figuring out what "something else" is. Doing this is worth the effort. It tells you a lot about your system, and it will improve your design (even if you end up usi

Crystal Dynamics announces layoffs, but says Tomb Raider will not be impacted

Crystal Dynamics, the studio behind the recent Tomb Raider games, announced an unspecified number of layoffs today. In a post on LinkedIn, the game developer kept the size of the cuts vague, only stating that "a number of our talented colleagues" would be impacted. In what's becoming an all-too-familiar refrain, the company cited "evolving business conditions" as the reason for the layoffs. "This decision was not made lightly," the post reads.

Using information theory to solve Mastermind

How you've just played optimal Mastermind Mastermind is a game all about information. The Code Master selects one of $ 6^4 = 1\,296 $ secret codes. Each incorrect guess gives us information by eliminating some of these; the more codes that are ruled out, the more information that guess has provided. Let's quantify this insight! Suppose a guess gets some response that reduces the number of possible keys from some number $n$ to a smaller $n'<n$. The convention in information theory, a branc

Verizon's Bringing Back That Landline Feeling With Its New Family Plan Feature

When we talk about a cellular "family plan," we mean a bundle of several individual phone lines for each person in a typical household. The plan usually includes features like high-speed data or a streaming video service that each family member can share. Now, Verizon has updated an add-on for its phone plans that's meant to bring the family closer together. The Verizon Family Plus perk, which offers features such as location check-ins and content filters, now includes Family Line, where up to

Both DHL and UPS currently have no working solution, so on their advice, we are temporarily suspending all shipments to the USA effective immediately. The issue is that we are now required to collect all taxes and tariffs on U.S. shipments in advance. However, there is no functioning calculator for this, which has created chaos.

Busy beaver hunters reach numbers that overwhelm ordinary math

But just how much harder? In 1962, the mathematician Tibor Radó invented a new way to explore this question through what he called the busy beaver game. To play, start by choosing a specific number of rules — call that number n. Your goal is to find the n-rule Turing machine that runs the longest before eventually halting. This machine is called the busy beaver, and the corresponding busy beaver number, BB(n), is the number of steps that it takes. In principle, if you want to find the busy beav

Thus, the rational numbers are seen to be incomplete. One seeks to complete them, to fill these holes, forming the real number line ℝ.
