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.

Nicola Wrachien with Silicon Labs created this fun handheld, porting Quake using the Arduino Nano Matter. For easy playing a custom controller shaped board was designed with joysticks and a screen.

For a much tougher challenge, a group from Silicon Labs decided to port DOOM‘s successor, Quake, to the Arduino Nano Matter Board platform instead even though this platform has some pretty significant limitations for a game as advanced as Quake.
<https://community.silabs.com/s/share/a5UVm000000Vi1ZMAS/quake-ported-to-arduino-nano-matter-and-sparkfun-thing-plus-matter-boards?language=en_US>
To begin work on the memory problem, the group began with a port of Quake originally designed for Windows, allowing them to use a modern Windows machine to whittle down the memory usage before moving over to hardware. They do have a flash memory module available as well, but there’s a speed penalty with this type of memory. To improve speed they did what any true gamer would do with their system: overclock the processor. This got them to around 10 frames per second, which is playable, but not particularly enjoyable.
The further optimizations to improve the FPS required a much deeper dive which included generating lookup tables instead of relying on computation, optimizing some of the original C programming, coding some functions in assembly and only refreshing certain sections of the screen when needed.](https://nerdculture.de/system/media_attachments/files/114/206/081/241/901/037/original/72dec8d287dd1c33.png "[ImageSource: Nicola Wrachien]

GitHub uncovers new Ruby-SAML Vulnerabilities allowing Account Takeover Attacks.Two high-severity security flaws have been disclosed in the open-source ruby-saml library that could allow malicious actors to bypass Security Assertion Markup Language (SAML) authentication protections.

"Attackers who are in possession of a single valid signature that was created with the key used to validate SAML responses or assertions of the targeted organization can use it to construct SAML assertions themselves and are in turn able to log in as any user," GitHub Security Lab researcher Peter Stöckli said in a post.
The Microsoft-owned subsidiary also noted that the issue boils down to a "disconnect" between verification of the hash and verification of the signature, opening the door to exploitation via a parser differential.
Versions 1.12.4 and 1.18.0 also plug a remote denial-of-service (DoS) flaw when handling compressed SAML responses (CVE-2025-25293, CVSS score: 7.7).
⚠️Users are recommended to update to the latest version to safeguard against potential threats.⚠️
The findings come nearly six months after GitLab and ruby-saml moved to address another critical vulnerability (CVE-2024-45409, CVSS score: 10.0) that could also result in an authentication bypass.](https://nerdculture.de/system/media_attachments/files/114/177/947/075/555/612/original/721ecee68734690f.jpeg "[ImageSource: GitHub]

The feat was devised by Software Engineer Dmitri Mitropoulos, founder of Michigan Typescript and co-founder of Squiggleconf. He released a video showcasing the results of a year-long effort to get Doom running inside of Typescript's Types system.

Typescript is a language built on top of Javascript, that add static typing to catch many errant mistakes before your executes, think of it as guardrails which check that functions and other variables are being used correctly. While this is commonly used in all kinds of development, it's unheard of to run a game within Typescript's Type system.
The port itself runs inside three and a half trillion lines of types, totalling a gargantuan size of 177 TB. This is run through Typescript's Type tracker, which takes 12 days to compile the first frame of Doom (0.0000009645 fps). This meant that 20 million type instantiations were running every second in order to get the output.
Mitropoulos explained in the Michigan TypeScript Discord server that this could be improved to take "1 to 12 hours", as long as someone works on it, with the developer noting that he has notes for where potential performance optimizations could be made.
<https://discord.gg/pfKUSmSY>
This was done by running the project within a custom WASM runtime, which is then processed through Typescript within an editor to display a frame.

To do this, the developer needed to remove limitations within the Typescript compiler itself, highlighting just how large the project got, with the Type tracker runtime consuming over 90 GB of RAM while it was running.
This huge overhead meant that common tools within Typescript could not be used, which meant that the herculean task of encoding every element of Doom in types. This required learning to develop elements like an L1 CPU cache, within Typescript Types itself. Due to Typescript requiring iteration on a single string from the left-hand side, binary algorithms had to be input in reverse.
"Oh, and AI can't help" Dmitri Mitropoulos added, describing that the work was so low level that AI couldn't possibly assist with any of the tasks. Too bad, Grok 3.
Mitropoulos said that he undertook the challenge after completing "every other" Types challenge, and wanted to understand why Doom wouldn't be able to run within Types. However, he managed to find "ridiculous" workarounds to make it all work, despite his own disbelief in the project.](https://nerdculture.de/system/media_attachments/files/114/166/742/069/675/680/original/110e43577d22fe1d.jpeg "Dmitri Mitropoulos further explained that each value within the Typescript Types system equates to a line of pixels [totalling 128,000 lines of pixels in total], resulting in a \"resolution\" of 320x200, displayed in ASCII.
