📄 Minimal Linux OS runs in a 6MB PDF Document in Chrome.A version of the Linux operating system can now be run inside a PDF opened by a Chromium-based browser. The developer [Ading2210] explains that Linux need a modified version of the TinyEMU RISC-V emulator.

![If you wish to try out the LinuxPDF, it requires a Chromium-based browser to work correctly (I checked, but it didn't work in Firefox on PC).
On the topic of speed and efficiency, [Ading2210] humbly admits that performance might be the largest problem with LinuxPDF. "The Linux kernel takes about 30-60 seconds to boot up within the PDF, which [is] over 100x slower than normal," notes the developer. With Chrome's current PDF engine having its Just-in-Time (JIT) compiler disabled, [Ading2210] sees no way of speeding up the code, for now.](https://nerdculture.de/system/media_attachments/files/114/211/704/385/933/637/original/7142a6047423bdbc.jpeg "If you wish to try out the LinuxPDF, it requires a Chromium-based browser to work correctly (I checked, but it didn't work in Firefox on PC).

The TinyEMU RISC-V emulator runs in the PDF thanks to a technique where its code is compiled "using an old version of Emscripten that targets asm.js instead of WebAssembly." This is embedded and loads in the PDF, subsequently auto-running a minimal Linux kernel targeting that architecture.
In this implementation, once you agree to 'Start Emulator' in your browser, you will see the LinuxPDF UI load, and a welcome message in the Linux viewport, as you wait for the OS to boot.](https://nerdculture.de/system/media_attachments/files/114/211/705/349/712/707/original/513838969c81eb99.png "[ImageSource: Ading2210]

Below the Linux viewport in the PDF is a soft keyboard created by an array of PDF buttons. However, it is likely quicker for everyone with a decent physical keyboard to input commands into the 'type here for keyboard inputs' field to the lower right of the keyboard UI area.](https://nerdculture.de/system/media_attachments/files/114/211/706/326/556/776/original/9f7e2d1a8c32c083.png "[ImageSource: Ading2210]

Threat actors are taking advantage of the rise in popularity of DeepSeek to promote two malicious infostealer packages on the Python Package Index, where they impersonated developer tools for the AI platform.

The malicious packages, deepseeek 0.0.8 and deepseekai 0.0.8 were uploaded to PyPI on January 29, 2025, with only twenty minutes between them.
Positive Technologies quickly discovered and reported them to PyPI, which quarantined and blocked downloads of the packages, followed by their complete deletion from the platform.
Despite the quick detection and response, 222 developers downloaded the two packages, most from the United States (117), followed by China (36), Russia, Germany, Hong Kong and Canada. Those developers who utilized these packages should immediately rotate their API keys, authentication tokens and passwords, as they may now be compromised.](https://nerdculture.de/system/media_attachments/files/113/963/687/409/845/888/original/26ce13670f89cd53.png "[ImageSource: Positive Technologies]

Malicious payload contained in both packages.
The stolen information was exfiltrated to a command and control (C2) server at eoyyiyqubj7mquj.m.pipedream[.]net using Pipedream, a legitimate automation platform. Threat actors could use this stolen information to access cloud services, databases and other protected resources utilized by the developer.
"Functions used in these packages are designed to collect user and computer data and steal environment variables", reads the Positive Technologies report. "The payload is executed when the user runs the commands deepseeek or deepseekai (depending on the package) in the command-line interface."
"Environment variables often contain sensitive data required for applications to run, for example, API keys for the S3 storage service, database credentials, and permissions to access other infrastructure resources."](https://nerdculture.de/system/media_attachments/files/113/963/688/343/436/642/original/9a479c6c50735793.png "[ImageSource: Positive Technologies]

The tech giant also noted it prevented 1.3 million apps from getting excessive or unnecessary access to sensitive user data during the time period by working with third-party app developers.

NESFab has some smart features developers of NES games will certainly appreciate, most notably automatic bank switching. Instead of doing this manually, but NESFab will automatically carve your code and data up into banks to be switched in and out of memory when needed.

![“NESFab is a new programming language for creating NES games. Designed with 8-bit limitations in mind, the language is more ergonomic to use than C, while also producing faster assembly code. It’s easy to get started with, and has a useful set of libraries for making your first (or hundredth) NES game.”
There’s also an optional map editor, which makes it very easy to create additional levels for your game. All in all, a very cool project I hadn’t heard of, which also claims to perform better than other compilers.

I'd like to compile some arguments and ideas to make life easier at work, but I think sourcing from beyond my own perception can be helpful.
Are you a #software #developer who has #adhd or #autism (or both)? What are the conditions or accommodations that help you thrive at your job?
*Boosts for reach are welcome and appreciated.*
I'm an #iOS and #macOS #software #developer, experienced in #UIKit, #AppKit, #ObjectiveC, #Swift and #SwiftUI, have worked with the #Parse framework as well as #Realm / #MongoDB and the whole toolchain around it. I have been working in software development for about 30 years and am looking for a remote position (permanent role, preferably in an AT/DE startup).
So if you know someone who knows someone. Thanks for sharing. 🙏🏻
