Ask HN: What's a good 3D Printer for sub $1000?

At least a 256x256x256mm print volume. Needs to be enclosed or enclosable. Need to be able to print with more durable, temperature/chemical resistant materials such as PC/Nylon/ABS or infused materials. I do not need to print multi material models. I would prefer something that doesn't phone home and can work offline. Opensource firmware/software and repairability are important. I am ok assembling the machine and learning how to dial it in. I can do CAD work and make models by hand; I was a mac

Nothing’s generous Phone 3 loyalty deal puts trade-ins to shame

Ryan Haines / Android Authority TL;DR Nothing is offering $300 off the purchase of a Phone 3. To get the deal you need to submit the IMEI of your Phone 1 or Phone 2. No trade-in is required, but there are some important restrictions to be aware of.

Show HN: Making a cross-platform game in Go using WebRTC Datachannels

(The following was adapted from a talk I gave at DWeb Weekend 2025 at the Internet Archive in San Francisco on August 17, 2025) Simplifying WebRTC Datachannels for Games First of all, to get some stuff out of the way, instead of using the “super complicated” WebRTC datachannels, why don’t we use something simpler?

Apple Store Goes Down Ahead of iPhone 17 Event

In the series of predictable events leading up to every iPhone launch is the moment the Apple Store goes down -- and it's just happened. There's just hours to go until the Apple event, during which the company is set to announce the iPhone 17 series and updates to its wider product lineup, including the Apple Watch Series 11. For now, when you take a trip to the tech giant's online emporium, it features the familiar boilerplate text: "Be right back." When the store pops back up later today, the

Don’t let outdated IGA hold back your security, compliance, and growth

If organizations want to have any chance of protecting their data from unauthorized access in 2025 and beyond, there is no way around Identity Governance & Administration. But conventional IGA solutions are the wrong option for most businesses. For companies trying to keep their data secure while maintaining a competitive edge, the stakes could not be higher. Faced with an onslaught of identity-based attacks, they need a way to efficiently manage their increasingly complex IT environments while

‘KPop Demon Hunters’ Songwriter on Crafting the Movie’s Breakout Hit

The biggest earworm from KPop Demon Hunters, “Golden,” has helped propel the hit Netflix and Sony animated feature to success atop both the streaming and music charts. And now we know a bit more about the lore behind the Huntr/x track. Songwriter and singing voice of Rumi, one of the film’s lead demon hunters, EJAE talked about the film’s breakout song with Variety. “One of the biggest assets I brought to the movie, or when writing the songs, was being bilingual,” she shared about bringing cul

How to Clean Your Dog's Ears and Clip Your Cat's Nails—Experts Weigh In (2025)

The internet is filled with questions like “How to clean your dog's ears?” to “Do you really need to brush your pet's teeth?” Thanks to the crowdsourcing nature of the web, there's a bevy of instructional TikToks and fellow pet parents engaging in heated debates on everything from what your dog's poop means to how to best clip your cat's nails. With so much information to sift through, I decided to test some pet hygiene products on my cats, chat with experts like vets and groomers, and do a lit

10 pocket-sized tools that make life easier - and how I use each

My keychain essentials. Adrian Kingsley-Hughes/ZDNET Follow ZDNET: Add us as a preferred source on Google. I've collected my fair share of multitools and gadgets, but I've lost track of how often I've needed one -- only to realize it's sitting at home or in the car. Carrying a full toolbox everywhere just isn't practical. What I do have with me almost all the time, though, is my keychain -- and it turns out, it's the perfect way to keep essential tools within reach. Also: Are Amazon Basics t

Deepnote (YC S19) is hiring engineers to build a better Jupyter notebook

We started Deepnote to help data teams solve the hardest problems. We don’t just need better algorithms, bigger data sets, and more computing power. We need tools that help us explore, collaborate, and share. These tools don’t exist yet. We need to invent them first. Data work is as much a scientific and creative process as it is an engineering one. It involves working together, failing, learning, and going back to the drawing board. Data professionals are explorers. To make projects successful

Simple prompt or agent workflow? How not to overthink AI

Start with the simplest tool that solves your problem. Sometimes you'll need a prompt, and other times an agent workflow. "You're probably making AI harder than it needs to be." This advice from Corey Noles and Grant Harvey's latest episode of The Neuron podcast urges greater simplicity in what has become a complicated and c

A mini-book on AWS networking

If you have ever tried to put an app on AWS, you know that you first need to absorb a ton of knowledge about AWS networking. Before you set up that first EC2 instance, you need to know terms like VPCs, subnets, security groups, and internet gateways. You need to remember how CIDR notation works, and that networking class you took suddenly feels like a long time ago. Without a solid understanding of AWS networking, you may be able to start up an EC2 instance, but you will have a hard time getting

Worried About Losing Your Job? Pack a Digital Go Bag

Getting fired by email or by being locked out of your work laptop is not normal. And yet it's happening to US workers who have few rights and protections under the law. Even federal government employees who formerly had some of the most secure jobs and strong unions are getting axed without warning. You may not be able to protect yourself from an unexpected job loss, but you can make sure that your most important information doesn't get held hostage by your former employer. To do that, you need

The MiniPC Revolution

Vibe Debugging: Enterprises' Up and Coming Nightmare

It's 12:45 PM, and my morning has vanished into the black hole of debugging my vibe-coded meme stock valuation site. The monthly growth numbers are spitting out garbage. What should be a steady 3-5% is showing wild swings between -50% and +2000%; the numbers don't add up.

Good system design

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.

Swiss vs. UK approach to major tranport projects

Start with the timetable So, let’s imagine the UK had done this in 2008. What might the planners have noticed? Well, first up, they'd have spotted that our major cities need more frequent and faster rail connections from suburbs to centres and that these are prevented at the moment by insufficient platform capacity in stations like Leeds, Manchester Piccadilly and Birmingham New Street. So we need more station capacity in our city centres. They'd have identified that many suburban lines into
