Most e-readers lock you into one screen, one store, and one way to read your digital library without much choice or flexibility. For book lovers who crave the feel of a real book, the freedom to own their library outright, and the ability to repair their devices without manufacturer permission or expensive service plans, mainstream options from Amazon and Kobo can feel frustratingly limiting and restrictive.

Diptyx is an open-source, dual-screen e-reader that changes this dynamic entirely. Designed by Martijn den Hoed, this device features a book-like design, modular hardware, and DRM-free reading capabilities. It’s built for tinkerers, readers, and anyone who wants to truly own their digital books and the device that displays them without corporate gatekeepers controlling access.

Diptyx’s form factor is instantly familiar and comforting. Two 5.83-inch e-ink screens open like a hardcover book, displaying two pages at once and closing to protect the displays without requiring a separate case. The device is slim, lightweight at 300 grams, and portable, making it perfect for reading on trains, planes, or curling up at home.

The modular case, visible screws, and user-replaceable SD card and batteries make repairs and upgrades easy for anyone comfortable with basic tools. When a component fails or new technology emerges, you can fix or upgrade Diptyx yourself rather than buying a whole new device, extending its lifespan and reducing electronic waste from landfills.

Powered by an ESP32-S3 processor, Diptyx runs custom open-source firmware currently designed primarily for EPUB reading. Upload your books via USB-C, adjust fonts and margins to your preference, and personalize your experience without accounts, cloud services, or digital rights management restrictions. However, format support is currently limited to EPUB files, meaning PDF, MOBI, or other formats require conversion before reading on the device.

The open firmware invites community contributions and modifications from developers worldwide. Developers can add Wi-Fi capabilities for RSS feeds, custom games, or even offline Wikipedia access for reference. The firmware is released under the MIT license, encouraging users to fork, modify, and share improvements with the growing community of Diptyx users who value open technology and collaborative development.

Dual 1500mAh batteries and efficient circuitry mean Diptyx runs for weeks on a single charge, with deep sleep mode extending standby to months. When it’s time for a recharge, USB-C makes it convenient and fast. If a battery ever fails or degrades over time, you can swap it yourself using basic tools and readily available replacement parts.

Diptyx’s minimalist design, black-and-white e-ink screens, and tactile case feel satisfying to hold and use during daily reading sessions. The device fits equally well in a backpack, on a nightstand, or in a maker’s workshop environment. For readers who value ownership, privacy, and the joy of tinkering with their technology, Diptyx offers a rare e-reader that puts complete control back in your hands.

Clair Obscur: Expedition 33 developer Sandfall Interactive and publisher Kepler Interactive have announced a "major game update" is in development for the Game of the Year contender, according to a news release. Creative director Guillaume Broche noted the update is intended as a "'thank you' to [the game's] fans for their support."

Scientists have built an artificial neuron that’s so realistic it fires, learns, and responds to chemical signals just like the real thing – a breakthrough that could transform computing, medicine, and the way that tech merges with biology.

Cyberpunk 2077 is coming to macOS later this week, after it was originally set to debut in early 2025. Cyberpunk 2077: Ultimate Edition will officially be available for Apple silicon devices for the first time on July 17th, from Apple’s own Mac App Store, Steam, Epic Games Store, and GOG.com.

CD Projekt Red has optimized Cyberpunk 2077 for a variety of Mac hardware, all the way from the early M1 models up to the latest M4 chip family. Only some M1 and M2 Macs are supported, though — you’ll need a Mac with 16GB or more of unified memory to play Cyberpunk 2077, so base 8GB M1 and M2 chips won’t be compatible.

There will be graphics presets that are optimized for each Apple silicon model, and more powerful Apple silicon chips will also fully support features like path tracing, a film-like full ray tracing mode that greatly improves lighting and occlusion in the game.

AMD’s FSR upscaling and frame generation will also be available in Cyberpunk 2077 on Mac, helping the game feel more smooth with options like path tracing enabled. MetalFX upscaling is also available, alongside support for Apple’s Magic Mouse and Trackpad hardware.

Apple and CD Projekt Red haven’t shared performance data for what to expect across different Apple silicon Mac configurations. If you own an Apple XDR display, or any other HDR monitor, you’ll get HDR support in Cyberpunk 2077, and there’s even spatial audio and head-tracking with Apple AirPods.

Mac owners have technically been able to run Cyberpunk 2077 on their devices for a couple of years now, thanks to Apple’s own Proton-like game porting tool. This official release means the game takes full advantage of Apple silicon and Apple’s native Metal graphics APIs, including Apple’s Tile-Based Deferred Rendering (TBDR) architecture.

Cyberpunk 2077 debuts on Mac just as CD Projekt Red releases the latest 2.3 patch for the game, which includes additional cars and a new photo mode. Cyberpunk 2077: Ultimate Edition on Mac will support cross progression across all platforms, and includes the Phantom Liberty expansion and all of the major updates to the game so far.

President Donald Trump’s Department of Justice is coming after us.

That’s not a metaphor. It’s real. 

I wish I could tell you more, but I’m not allowed to say anything further. Convenient, isn’t it? A perfect gift for an authoritarian regime—using the power of the state to silence dissent and debate, all while shielding Trump from criticism.

We’ve watched them go after ActBlue. After Media Matters. I guess it was inevitable that we’d get our turn.

But you all know me: I don’t back down from a fight. This is what I’m built for. Mounting a vigorous legal defense doesn’t come cheap, though. And as you all know, independent media isn’t flushed with cash these days. We certainly aren’t. 

You—our supporters—got us through our legal fight with Robert F. Kennedy Jr., and I’m counting on you to help us now. I’m not exaggerating when I say that this one is existential. 

So please contribute to Daily Kos’ legal defense.

Honestly, we were planning to fundraise for something entirely different—the next great version of Daily Kos. A new platform built for this community, with the features you’ve been begging for over the last two decades.

I can’t wait to tell you all about it. I’m downright bursting at the seams!

But first? We’ve gotta deal with this bullshit. 

Here are other ways to support us in this fight.

As always, thank you for being here. We couldn’t do this without you.
