Images, undated and uncaptioned, include Vladimir Nabokov lines written on women and show Bill Gates and Noam Chomsky

Democrats on the House oversight committee have released a new batch of photos from the estate of convicted sex offender, Jeffrey Epstein, as the deadline for the justice department to release its files related to Epstein looms.

The images, released on Thursday, are undated and lack captions or context. Among them are photographs of what appear to be lines from Vladimir Nabokov’s novel Lolita written on different parts of a woman’s body.

In a statement after the release Robert Garcia, a US representative and ranking member of the committee on oversight and government reform, said that “oversight Democrats will continue to release photographs and documents from the Epstein estate to provide transparency for the American people.”

“As we approach the deadline for the Epstein Files Transparency Act, these new images raise more questions about what exactly the Department of Justice has in its possession,” he said.

Here, my summary of key features and decisions of Guix:

1. Guix is a package manager that can (optionally) run on top of Linux distributions or other POSIX systems, like cargo, pip, conda or Conan. In difference to the pip and cargo package managers, it is language-agnostic, supports many different build systems and languages, and features around 29000 packages now.
2. Guix allows to define a fully reproducible system. This works by using a declarative language for immutable version-controlled package descriptions, and by deriving any software from package definitions and a fixed version (commit hash) of the source code. In that, it is similar but much stricter than Nix and NixOS. The key point is that any software built, and all its dependencies, go back to unambigously, immutable versions of source code and build recipes - and all inputs to the system are open source and can be reviewed.
3. Important for programming, this can also define isolated build and development environments, like Python's venv, but also Docker containers. This means that Guix can be used to develop, build, package, and deploy software, very much like Snap packages. And that's independent from the distribution you work in, very much like pip or cargo are independent from the system you work in. (And yes, it supports Rust!).
4. This allows it, and also makes it technically possible, that any software package can be re-built and run years later. To make this legally possible, the official distribution of Guix also demands all components to be open source (FOSS). This is also a key difference to NixOS and non-free forks of Guix, which allow non-free binary packages, but sacrifice reproducibility. (To illustrate: If you have a binary, proprietary scanner driver in NixOS, and the owning company practices planned obselescence and decides that you should buy their new hardware, and pulls that driver, you are out of luck. In Guix, this can't happen.) (Note that as your own private conponents, you can define any package you like, you can also distribute your definitions as a complement to GNU Guix. Non-free packages for Guix do exist, in the same way as you can buy and run Steam Games software for Linux. Such non-free software just can't become part of the official Guix distribution, just like Amazon or Apple can't sell their non-free software via Debian or the Linux kernel project (or, for that matter, Apple has no obligation to market and distribute, say, Oracle products).
5. All inputs being open source also means that any software component can be reviewed, that mis-features such as privacy-invasive behaviour can be removed, and that it is hardly possible to hide malware in the system. Because this also applies recursively to all compilers and build tools, this solves also Thompson's "Trusting Trust" problem. In fact, the whole system can be build from a 512 byte binary root (called MER). (Interestingly, that level of user control gets a lot of hate online -- certain companies don't seem to like it).
6. Because it would take too long to build every user package from source every time, the produced packages are normally cached (while their correct binary content can be easily verified).
7. The declarative description language for the packages is a well-defined, established, minimalist language called Scheme. This is a member of the Lisp family of languages. That Lisp is very well suited for declaratively building and configuring large systems has been proven with GNU Emacs, whose software, but more importantly, whole user configuration, is written in Emacs Lisp.
8. The Scheme implementation used is called Guile. It has especially good support for the POSIX environment and has also much better-than-average interactive debugging capabilities compared to other Scheme implementations.
9. Also worth noting is that the Guix project has superb online documentation. This is a practical advantage compared to Nix.

As example: you are on Debian stable and quickly want to try a recent version of the kakoune editor (as kakoune is in ongoing development): They are available under the Guix package manager. Just

guix install kakoune

and bang you have it!

According to sources close to Reuters, China has developed a working prototype of an EUV machine, which is currently undergoing testing. This domestic achievement involved Chinese companies successfully reverse-engineering ASML's EUV lithography scanners and creating a functional version using second-hand components. The new EUV prototype reportedly takes up an entire factory floor, comparable in size to modern High-NA EUV machines from ASML. Chinese companies are said to have obtained parts from older ASML machines on secondary markets. The Chinese government initially set a goal of producing working chips from the prototype by 2028.

weak shit, smh give me some novel free electron laser shit, mrx chinese

In early 2025, we reported that a new EUV machine was undergoing testing at Huawei's Dongguan facility. This machine leverages laser-induced discharge plasma (LDP) technology, representing a potentially disruptive approach to EUV light generation. The LDP approach used in the Chinese system generates 13.5 nm EUV radiation by vaporizing tin between electrodes and converting it to plasma through high-voltage discharge, where electron-ion collisions produce the required wavelength. This methodology offers several technical advantages over ASML's laser-produced plasma (LPP) technique, including a simplified architecture, reduced footprint, improved energy efficiency, and potentially lower production costs.

although tpu suggest they are not doing full reverse engineering, but what on earth could take that much space with different light emission mechanism, they don't need tin inkjet printers
