Hi HN! We’re Jimmy and Ray. Jimmy is a Thiel Fellow with a Ph. D. from MIT who has worked on programming tools for 15 years; Ray became VP of Sales at a $2B company when he was 19 and has built side-businesses vibe-coding. Last year, we set to answer the question “If AI can write code 100x faster, then why aren’t you shipping 100x faster?” What we learned shocked us — even fairly nontechnical people and solo founders told us they were spending more than half of their development time reading the

Linux 7.1 Boosts Intel Arc, Flatpak Integrates ROCm, Vintage AMD Driver Refined Today's Highlights Recent developments enhance GPU performance and accessibility, with the Linux 7.1 kernel providing significant gains for Intel Arc Battlemage graphics. AMD's ROCm compute platform gains broader deployment potential through Flatpak 1.18 integration, while an older AMD GPU driver sees notable code cleanups. Linux 7.1 Helping Intel Arc Battlemage Graphics Achieve Better Performance (Phoronix) Source: https://www.phoronix.com/review/intel-b580-linux-71 Phoronix reports that the upcoming Linux 7.1 kernel release is delivering superior graphics performance for Intel's Arc B580 Battlemage desktop graphics card compared to the current stable Linux 7.0. This indicates ongoing, critical optimization work within the open-source Linux graphics stack, directly impacting the gaming and compute capabilities of Intel's latest GPU architecture. Such kernel-level improvements are vital for unlocking the full potential of new hardware on Linux platforms, ensuring users receive the best possible experience from their Intel Arc GPUs. The performance uplift suggests that deeper integration and fine-tuning of the kernel's display and compute drivers are progressing, addressing potential bottlenecks and enhancing throughput. For users and developers leveraging Intel Arc GPUs on Linux, this kernel update is a significant milestone, promising more stable and efficient operation for various workloads, from gaming to professional applications. It highlights the dynamic nature of Linux driver development, where continuous collaboration leads to tangible performance benefits even before major hardware refreshes. Comment: This shows how crucial kernel updates are for modern GPUs on Linux. Early adopters of Arc Battlemage should definitely keep an eye on Linux 7.1 for a noticeable performance bump.

The ChatGPT maker announced it has filed paperwork to go public, just a week after rival Anthropic took the same step.

I built InvoiceAI an AI powered invoice generator that lets you describe what you want to invoice in plain English and get a fully formatted invoice in seconds, complete with PDF download and a real payment link. Here's how I built it for the #H0Hackathon. The Problem Freelancers and small businesses waste time manually creating invoices. You know what you did, who you did it for, and how much it costs you shouldn't have to fill out a form to capture that. The Stack - Vercel v0 — scaffolded the entire UI in one prompt Next.js 16 — framework Groq (Llama 3.3 70B) — AI natural language to invoice fields AWS DynamoDB — stores every generated invoice Paystack — generates real payment links jsPDF — client-side PDF generation Vercel — deployment How It Works User types: "50 hours of mobile app development at $80/hr for TechLagos Ltd, 7.5% VAT" Groq parses the text and extracts structured invoice data Live preview updates instantly User downloads PDF — invoice is saved to DynamoDB automatically One click generates a real Paystack payment link to send to the client Building the UI with v0 I used Vercel v0 to scaffold the entire UI in one prompt. It generated a production-ready Next.js component with a split-panel layout form on the left, live invoice preview on the right. I just had to wire up the AI and database logic. Connecting AWS DynamoDB Using the AWS SDK v3, I connected DynamoDB directly from Next.js server actions. Every time a user downloads an invoice, it's saved to DynamoDB with the client details, line items, tax rate, and timestamp. This gives the app a real data foundation that scales from day one. await dynamo . send ( new PutCommand ({ TableName : ' invoices ' , Item : { invoiceId : data . invoiceNumber , clientName : data . clientName , clientEmail : data . clientEmail , items : data . items , createdAt : new Date (). toISOString (), }, })) The Result AI generates invoice from plain English in under 2 seconds Real PDF download (no print dialog) Real Paystack

Ask almost any engineer what "Wi-Fi" stands for and you'll hear the same answer: "Wireless Fidelity." It is one of the most repeated facts in tech, it appears in textbooks and product manuals, and it is wrong. Wi-Fi does not stand for Wireless Fidelity. In fact, it does not stand for anything at all. A name invented by a branding agency In 1999, the industry group then known as the Wireless Ethernet Compatibility Alliance — today the Wi-Fi Alliance — had a problem. The wireless networking standard it was promoting carried the memorable name "IEEE 802.11b Direct Sequence." That string is precise, but no consumer was ever going to ask a store clerk for an 802.11b router. The technology needed a brand. So the alliance hired Interbrand, the same firm behind names like Prozac and the Compaq brand, to invent something catchy. Interbrand returned with a shortlist of about ten candidates, and the group chose "Wi-Fi." Phil Belanger, a founding member of the alliance, has been blunt about it for years: the name has no expanded meaning. It was picked because it was short, easy to say, and rhymed with "Hi-Fi," a term consumers already associated with high-quality audio gear. So where did "Wireless Fidelity" come from? The myth has a real origin. Some board members were uncomfortable shipping a brand name that "meant nothing," so the alliance briefly bolted on the tagline "The Standard for Wireless Fidelity." It was a backronym — two words reverse-engineered to fit the syllables "Wi" and "Fi" after the fact. The phrase was clumsy, it never described the technology accurately, and once the alliance brought on more marketing-savvy members it was quietly dropped. The tagline disappeared; the misconception it planted did not. Why this matters if you build connected things This is a fun piece of trivia, but it points at something real for anyone doing IoT and embedded development . The protocols we treat as immovable technical bedrock are often shaped as much by branding, licensing,
