Ergonomic errors in Rust: write fast, debug with ease, handle precisely

Ergonomic errors in Rust: write fast, debug with ease, handle precisely Errors show up in three distinct contexts: when you’re writing code, when you’re debugging code, and at runtime when the program needs to handle recoverable errors. And errors are consumed by two distinct consumers with different needs: the developer debugging an application, and the caller making error handling decisions at runtime. In this post, we’ll explore how stackerror is designed to make working in all three contex

I'm too dumb for Zig's new IO interface

I'm too dumb for Zig's new IO interface You might have heard that Zig 0.15 introduces a new IO interface, with the focus for this release being the new std.Io.Reader and std.Io.Writer types. The old "interfaces" had problems. Like this performance issue that I opened. And it relied on a mix of types, which always confused me, and a lot of anytype - which is generally great, but a poor foundation to build an interface on. I've been slowly upgrading my libraries, and I ran into changes to the tl

Best Standing Desks of 2025

What I like: When cable organization is the goal, the Autonomous SmartDesk 5 Pro is the desk. All of the cable management items, like a 3M cable organizer, cable management tray and magnetized cable runner, come included with the desk. With all the cables managed and out of the way, you have a lot of desktop space to play with. The SmartDesk 5 Pro is an electric motor desk that is quiet, quick and very easy to use and has three memory options. When you're choosing your heights and free-adjusti

The Maker of Ozempic Is in Such Deep Trouble That It’s Going on Hiring Lockdown

Image by Sergei Gapon / AFP via Getty / Futurism Rx/Medicines Novo Nordisk, the Denmark-based pharmaceutical company that makes Ozempic and Wegovy, looks like it's being toppled off its GLP-1 throne. In a statement to Reuters, the Danish conglomerate admitted that it "currently [has] a hiring freeze in non-business critical areas." Though Novo offered no additional explanation, the writing has been on the wall for months that the once-dominant drug manufacturer is in big financial trouble. D

Show HN: NextDNS Adds "Bypass Age Verification"

We just shipped a new feature in NextDNS: Bypass Age Verification. More and more sites (especially adult ones) are now forcing users to upload IDs or selfies to continue. We think that’s a terrible idea: handing over government documents to random sites is a huge privacy risk. This new setting workarounds those verification flows via DNS tricks. It’s available today to all users, including free accounts. We’re curious how the HN community feels about this. Is it the right way to protect priva

SIMD Binary Heap Operations

SIMD binary heap operations Author: Wojciech Muła Added on: 2025-01-18 Introduction Binary heap is a binary tree data structure having some interesting properties. One of them is an array-friendly memory layout, achieved by building (almost) complete binary tree. A binary heap keeps at index 0 the maximum value, or the minimum one depending on convention — let's stick to maximum heaps. There is exactly one invariant: a child node, if exist, keep a value less than the parent node. For compariso

Why You Need an Outdoor Air Quality Monitor (2025)

It wasn’t that long ago that few people were monitoring the air—not the government, not its citizens. Today, weather apps provide estimates of outdoor air quality, and the government’s own air quality monitoring website, AirNow, has an easy-to-use zip code portal and fire and smoke map. There are real health benefits to owning an air quality monitor. Each US state is responsible for developing its own monitoring plan. Even in densely populated urban areas, outdoor air monitors owned by federal,

The 8BitDo Pro 3 Is So Dang Customizable, You’ll Never Need Another Controller

2025 Of all the lower-cost, pick-up-and-play controllers I tested for the Nintendo Switch 2, 8BitDo’s $60 Ultimate 2 easily felt the best in hand. At a steep discount from Nintendo’s now-$90 Switch 2 Pro Controller, it’s an easy recommendation. What else do you need? When we take a step up and look at the $70 Pro 3 wireless controller, we should consider just what we gain and what we’re still missing. No, unfortunately you can’t wake the Switch 2 from sleep with the Pro 3. What you get instead

8BitDo’s Pro 3 is a super customizable controller that’s too limited on Switch 2

As far as I’m concerned, 8BitDo’s Pro 3 is the ultimate controller. You may already know that it makes a model literally called the Ultimate controller, but it plays second fiddle to the new Pro 3 in some key ways. It’s highly customizable, allowing you to change the face buttons, joystick caps, and more. Let me explain: like most other 8BitDo controllers, it’s made to work on multiple platforms, but the Pro 3’s swappable ABXY face buttons allow it to actually transform as needed, say, if you’r

Under the Hood of AFD.sys Part 1: Investigating Undocumented Interfaces

A quick look at how I used WinDbg and NtCreateFile to craft a raw TCP socket via AFD.sys on Windows 11, completely skipping Winsock. Under the Hood of AFD.sys Part 1: Investigating Undocumented Interfaces Introduction This is the first post in a series about my deep-dive into the AFD.sys driver on Windows 11. The idea is that both this write-up and the library that comes out of it will be a one-stop doc set - and a launchpad - for poking at other drivers that don’t ship with an official spec.

I Forgot About the Battery Life on My Blink Outdoor Camera. That's the Best Part

CNET's key takeaways When I tested the Blink Outdoor 4, it was one of the first battery-powered models I had tried from the Blink security brand and, after testing dozens of outdoor cameras from different brands, I wasn't sure what to expect. Yes, Blink makes lofty claims that its lithium AA batteries last a ridiculously long time, but I've heard marketing lingo like that before. This compact wireless cam, however, stayed posted on my fence through all four seasons and well beyond as I waited -

C++26 Reflections adventures and compile-time UML

The first thing I do every time I need to learn a new codebase is to start drawing the UML diagram of its classes, and usually give up soon after I started. The process of doing it manually is certainly useful, but now with reflections I figure it would be fun to try generate it instead. With C++26 reflections[1] the general consensus is that the magnitude of language change is comparable to what happened with C++11. After my little experiment with it, I would cautiously agree. So how does one

Zig's New Writer

Zig's new Writer As you might have heard, Zig's Io namespace is being reworked. Eventually, this will mean the re-introduction of async. As a first step though, the Writer and Reader interfaces and some of the related code have been revamped. This post is written based on a mid-July 2025 development release of Zig. It doesn't apply to Zig 0.14.x (or any previous version) and is likely to be outdated as more of the Io namespace is reworked. Not long ago, I wrote a blog post which tried to expl
