Quake ported to Arduino Nano Matter. [Using only 276kb RAM]
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.

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]

US Nat'l Tsunami Warning Center NTWC cancels tsunami advisories for Puerto Rico, US Virgin Islands & British VI after sea level data indicates no destructive tsunami was generated by M7.6 sea floor #quake in the Caribbean. (While the US NTWC doesn't cover Caribbean islands closer to the quake, this sounds like [edit... nevermind, they retained the advisories closer to the quake].) https://www.tsunami.gov/events/PHEB/2025/02/08/25039000/4/WECA40/WECA40.txt #earthquake #geology

M7.6 #earthquake in the Caribbean Sea 209km SSW of George Town, Cayman Islands. A magnitude 7-8 #quake is capable of a local- to regional #tsunami affecting the Caribbean. Caution for sea level changes and unexpected currents. Data from USGS: https://earthquake.usgs.gov/earthquakes/eventpage/us7000pcdl/executive #geology
#Europe facing dual #seismic #crisis events with #earthquake swarm continuing at the Campi Flegrei super #volcano near #Naples, #Italy with strong #tremors: State of #emergency declared on #tourist hot-spot #Santorini in #Greece with largest #quake yet, region shaken by earthquakes every few minutes as thousands flee island: #travel #news #eruption
If you felt that Maine earthquake, be sure to fill out your paperwork! If you were in the area and others felt it, that information is important, too! Fill it out - it's a quick survey!

New England folks, sounds like you might have just felt an #earthquake centered off of York Harbor, #Maine? #quake #Boston
If you want to help scientists do their thing, please consider filling out the USGS "Did You Feel It" survey:

(I'm in meetings the rest of the morning & in Idaho, so I won't be responding here. Thanks for understanding.)
Before January 17 is over in my time zone, I should point out today has two historic #earthquake anniversaries:
* Northridge M6.7 1994 in California https://en.wikipedia.org/wiki/1994_Northridge_earthquake
* Kobe M6.9 1995 in Japan https://en.wikipedia.org/wiki/Great_Hanshin_earthquake
Lessons in construction learned from both. Apartments above ground-level garages (soft 1st story) have extra bracing after Northridge. Bridges/viaducts held by pairs of columns learned from a single-column expressway viaduct that toppled in Kobe.
#quake #geology #history #TDIH
I wish there were a way to filter out any comments regarding a quake below 4.5 that has happened or is happening in the #SFBA because anything below that level simply is NOT worth mentioning. 
The filter on my #MyShake app is set at that level & the only quake at that level which was recently reported was a 4.7 #quake in #Cobb on 1/1 that no one said 
about around here.

Geological Survey USGS - For the upcoming 20th anniversary of Dec 26, 2004 Sumatra-Andaman M9.2 #quake & Indian Ocean #tsunami, USGS recounts the events as data showed quake big enough to make a tsunami. And the Indian Ocean had no warning systems at the time to tell people on its shores. Lessons learned: today all ocean basins have tsunami sensors. More evacuation sirens being built. https://www.usgs.gov/news/featured-story/night-earth-shook #tsunami2004 #TDIH #history #earthquake #geology
