Cloudflare's Automatic Key Exchange Slashes TLS Retry Requests by 93%

Cloudflare has introduced a feature called Automatic Key Exchange (AKE) aimed at improving TLS handshake efficiency between its edge servers and origin servers. The technology addresses a longstanding inefficiency where mismatched key exchange preferences triggered HelloRetryRequests during TLS connections. Following deployment, the rate of HelloRetryRequests dropped dramatically from 52% to just 3.7%. This improvement reduces latency and computational overhead for origin servers handling HTTPS traffic routed through Cloudflare. The company detailed the technical implementation and results in a post on its official engineering blog.

Building AI Agents Demands a New Product Mindset Beyond Traditional SDLC

A growing perspective in software development argues that building AI agent-based products requires a fundamentally different approach than traditional software delivery. Rather than designing features users manually interact with, agentic products are built to understand user intent and act on their behalf, with the ability to plan, self-correct, and recover from failures. Architects must now design across three layers — patterns and capabilities, behavior and runtime, and operations — going well beyond simply integrating a large language model. The guiding principle is not maximum autonomy but the right level of autonomy for each specific capability. This shift demands what proponents call an 'Agentic Product Mindset' applied consistently across product, architecture, engineering, and operations phases.

Milldown app converts document folders to RAG-ready Markdown entirely on your Mac

A developer has released Milldown, a native macOS app that converts PDFs, Word files, spreadsheets, and other document formats into clean Markdown without uploading files to any external server. The app uses Apple's Vision framework for on-device OCR and is powered by Microsoft's open-source MarkItDown engine bundled locally within the app. Key features include folder mirroring, watch folders, RAG chunk export in Markdown or JSONL format, a command-line interface, and token-usage accounting. Benchmarks published by the developer show web pages require 72–95% fewer tokens than raw HTML, while PDFs use 71–84% fewer tokens than native PDF attachments. Milldown requires an Apple Silicon Mac running macOS 14 Sonoma or later, offers a 14-day free trial, and is priced at $39 for a perpetual single-user licence covering up to three Macs.

Valve Launches Steam Frame VR Headset at $1,049 Amid Stagnant Market

Valve has released a new virtual reality headset called the Steam Frame, priced at $1,049. The device represents the company's latest attempt to reinvigorate consumer interest in VR technology. The hardware arrives at a time when the broader VR market has struggled to maintain momentum after early enthusiasm.

Daydream App Lets Users Shop Outfits From Photos Using Apple Intelligence

Fashion app Daydream has launched new features powered by Apple Intelligence following the release of iOS 27. The update allows users to convert saved outfit photos from their camera roll into shoppable product results. Additionally, shoppers can now search for fashion items through Siri without needing to open the Daydream app directly. The integration leverages Apple's on-device AI capabilities to streamline the fashion discovery and shopping experience.

Valve's Steam Frame Wearable PC Reviewed: Comfortable but Costly at $1,059+

Valve has released the Steam Frame, a wearable PC that doubles as a headset, priced at $1,059 for the 256GB model and $1,299 for the 1TB version. Unlike conventional VR headsets, the device is positioned primarily as a wearable personal computer rather than a virtual reality peripheral. A reviewer at The Verge spent nearly three weeks testing the device, noting it weighs just over one pound and leaves no facial marks even after extended use. The Steam Frame costs two to three times more than visually similar headsets from Meta, making it a premium offering in the wearable display market.

Valve Steam Frame VR headset launches at $1,059, bundles Half-Life: Alyx

Valve has announced pricing for its Steam Frame headset, with the base 256GB model starting at $1,059 and a 1TB version priced at $1,299. The device is capable of running both flat and VR games locally, as well as streaming either type from a PC. Every unit will include a copy of Half-Life: Alyx, which Valve has optimized to run natively on the headset. The headset is available in multiple regional currencies, with European pricing set at €1,049 and UK pricing at £889 for the base model.

Valve bundles Half-Life: Alyx with new Steam Frame headset via ARM64 port

Valve has launched the Steam Frame, its first VR headset since 2019, priced at $1,059. Every unit comes bundled with Half-Life: Alyx, the acclaimed 2020 VR title. To make this possible, Valve ported the game to ARM64 so it runs natively on the headset's Qualcomm Snapdragon Gen 3 chip. This means buyers no longer need a separate VR-ready desktop or laptop PC to play the game. The port is a significant technical achievement given the game's original high hardware requirements.

Valve's Steam Frame Headset Reviewed After Three-Week Beta Test

The Verge's Sean Hollister spent three weeks beta-testing the Steam Frame, Valve's new mixed-reality headset that the company is careful not to label as a VR device. The device comes with controllers, an ergonomic accessories kit, and an Arcturus Vision Camera. Hollister described the Steam Frame as a potential glimpse into the future of cross-platform gaming. He hosted a live Q&A session at 4PM ET to answer reader questions about his hands-on experience with the hardware.

Dell XPS 13 (2026) Returns as a $700 Rival to Apple's MacBook Neo

Dell has revived the XPS 13 lineup with a 2026 model priced at $700, positioning it as a direct competitor to Apple's MacBook Neo. The company had previously considered retiring the XPS brand, but earlier resurrected it with the higher-end XPS 14 and 16 models. The new XPS 13 is designed as an affordable thin-and-light ultraportable, targeting a more budget-conscious segment than its predecessors. Reviewers note that its key hardware components — including the display, keyboard, trackpad, and speakers — are rated great to excellent. Outside of Apple's offering, the 2026 XPS 13 is considered among the best-built laptops available at its price point.

Why Argon2id Beats Faster Rivals for Secure Password Hashing

Argon2id is a memory-hard key derivation function designed to be deliberately slow and resource-intensive, making large-scale password-cracking attacks computationally expensive. Unlike older functions such as PBKDF2, which are vulnerable to GPU-based attacks due to their low memory requirements, Argon2id forces each derivation attempt to consume 64MB of RAM, limiting how many guesses an attacker can run in parallel. It is a hybrid of two Argon2 variants — combining GPU-cracking resistance from Argon2d with side-channel attack resistance from Argon2i — without leaving either weakness badly exposed. Configuration parameters like time cost, memory cost, and parallelism must be tuned to balance security against the performance needs of legitimate users. OWASP and other security bodies currently recommend Argon2id as the preferred choice for password storage and key derivation.
