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.

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]

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 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.

![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.
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.

What if you want to control a vehicle that’s hundreds of kilometers away, or even on the other side of the planet? Cellular is an option, but is obviously limited by available infrastructure — good luck getting a cell signal in the middle of the ocean.

![Modern remote control (RC) radios are capable of incredible range, but they’re still only made for line-of-sight use. But what if you could beam your commands down from space?
That’s what [Thingify] was looking to test when they put together an experimental RC boat using a Starlink Mini for communications. Physically, there was no question it would work on the boat. After all, it was small, light and power-efficient enough.
The downside? Starlink is a fairly expensive proposition; you’d need to have a pretty specific mission in mind to justify the cost. The Mini receiver currently costs $599 USD (though it occasionally goes on sale), and you’ll need at least a $50 per month plan to go with it. While this puts it out of the price range for recreational RC, [Thingify] notes that it’s not a bad deal if you’re looking to explore uncharted territory.](https://nerdculture.de/system/media_attachments/files/114/092/809/711/140/631/original/9e4cb0f46f9a54c5.jpeg "Modern remote control (RC) radios are capable of incredible range, but they’re still only made for line-of-sight use.

But would the network connection be up to the task of controlling the vehicle in real-time?
During early ground testing, the Mini version of the Starlink receiver worked very well. Despite being roughly 1/4 the size of its predecessor, the smaller unit met or exceeded its performance during benchmarks on bandwidth, latency and signal strength. As expected, it also drew far less power: the Mini’s power consumption peaked at around 33 watts, compared to the monstrous 180 W for the larger receiver.
On the water, there was even more good news. The bandwidth was more than enough to run a high-resolution video feedback to the command center. At the same time, the boat moved autonomously between waypoints, and when [Thingify] switched over to manual control, the latency was low enough not to be a problem. “We wouldn’t recommend manually piloting a high-speed aircraft over Starlink, but for a boat that’s cruising along at 4 km/h, the lag didn’t even come into play.”](https://nerdculture.de/system/media_attachments/files/114/092/811/040/659/614/original/c92e0ce273ebda10.png "[ImageSource: Thingify]

As expected, it also drew far less power: the Mini’s power consumption peaked at around 33 watts, compared to the monstrous 180 W for the larger receiver.
On the water, there was even more good news. The bandwidth was more than enough to run a high-resolution video feedback to the command center. At the same time, the boat moved autonomously between waypoints, and when [Thingify] switched over to manual control, the latency was low enough not to be a problem. “We wouldn’t recommend manually piloting a high-speed aircraft over Starlink, but for a boat that’s cruising along at 4 km/h, the lag didn’t even come into play.”")
Fan made Dreamcast Port of GTA 3 [Steals the Show].Thanks to [Stefanos] and his team, the genre defining Grand Theft Auto III [GTA 3], can now run on Sega’s hardware. Their combined efforts have yielded a fully playable port of the PC version of the game for Sega Dreamcast.

![The porting effort was years in the making. It began with reverse engineering the entire source code of GTA 3 then implementing it into the homebrew SDK for the Dreamcast, KallistiOS. All the in-game graphic and sound assets are only pulled from a user provided PC copy of the game. Steps for those seeking to compile a bootable Dreamcast image of their own have been provided on the project’s website.

Recently one of the original developers of GTA 3 [Obbe Vermejj], divulged that the game actually began development on the Dreamcast. The project was obviously transferred onto PlayStation 2 for commercial reasons, but with this port from [Stefanos] and crew, we no longer have to dream of what could have been.](https://nerdculture.de/system/media_attachments/files/114/087/246/934/693/980/original/4b01ad863ad1aaaf.png "The porting effort was years in the making.

As it turns out, Sega’s long defunct Dreamcast console is still thinking. The company behind the machine cut support long ago due in part to the commercial pressures applied by Sony’s PlayStation 2 console, but that never stopped the most dedicated of Dreamcast fans from seeking out its true potential.
This port of GTA 3 represents what could have been a true butterfly effect moment in console gaming history. The game was a major hit in the early days of the PlayStation 2, and it has been theorized that it could have proven to be a major commercial success for Sega as well had it been pressed onto a Dreamcast GD-ROM disc.](https://nerdculture.de/system/media_attachments/files/114/087/248/031/147/040/original/9e05caf297cb79fb.png "[ImageSource: Stefanos]
