Moved FRED (Fire Retardent Extinguishing Device). Cleaning up papers, bio-organic samples have been moved around. Crayfish tank has been upgraded. Leveraged the filter acquired from the diplomatic betta acquisition. Diplomatic betta materials have been located and moved. Documentation is being sorted currently. PCBs and other items have also been moved/relocated.
Soldering station needs to be set up to be movable. Internal drawer contents need to be changed around. Drafting tools have been located. Old parts relocated to safer areas.
Tools need to be located to 5S positions.
Found an old project below. Reverse engineering HDMI switcher that I bought in college. Reverse engineering is legal. Can it be frowned upon? It depends on why you are doing it.

Massachusetts has experienced a influx of snow. The term "Blizzard like conditions" has been used. Today's experiment involved introducing my californian cat Nebula (Nebulus Felinus Managerious) to snow. Nebula has determined that she does not like snow. Meowth (Meowthicus Felinus Managerious) already has data to determine that she does not like snow and has confirmed that she still does not like snow.

Today's reading is:
IEEE's FPGA Implementation of a Hardware-Optimized Autonomous Real-Time Radar Altimeter Processor for Interplanetary Landing Missions. https://ieeexplore.ieee.org/document/11107321.
Update: 3/11/2026: Regarding the navigation system mentioned in paragraph 1 of the Introduction, I assume that regarding radiation induced errors. One might be able to implement more sophisticated ENOB/ENOC to encode or error correct the errors as they come within the system. In paragraph 4, learning what a Ka-band radar altimeter (KaRA) is. I have found an article much leveraging altimeters from the 52nd International Astronautical Congress. Boldmethod indicates that altimeters indeed measure altitude. It is interesting their understanding of altimeters as it is reliant on air. There is data to indicate that air levels are a gradient and as the device mentioned in the article is reliant upon expansion and contraction from air pressure, they may be effective for a much farther distance than I would initially have thought. I would need to find articles with real data for suitability. Unrelated, OpenAltimetry is a thing. Not related to my project, good for exploration. Another site for consideration in the search for space grade altimeters is Sentiwiki. I am taking it that Altimeters for space application are specialty order and created, not available on the open market. Good to know for supply chain purposes, some engineer in the right place at the right time should leverage that. I know I am not in the right place to do so myself. Pass it on!
Kara System, paragraph 2 explains common sense radar methodology.
Specifications of Digital Subsystem of KaRA has a woderful list of specifications in which they may or may not follow.
Digital Subsystem Architecture Design paragraph 2 indicates that Xilinx are used very often within the industry.
Gain Control Estimator paragraph 2 thoughts, regarding "Initially, the RAP receives data with high attenuation, gradually adjusting the gain." - Do they continually stabilize the gain as time goes on? Filtering process with Operational Amplifiers?
Spectrum Computation and Peak Estimation, paragraph 2 pseudo-code.
Field Test, paragraph 1 indicates I need to look into Beechcraft as I am unfamiliar with their equipment. Interesting planes. Free advertising, not sponsored.
Environmental Test section Fault Recovery Mechanism - what was the priority of the flag? From hardware or digitally implemented on top of an overarching network above the level? MIT CSAIL and Facebook has an intriguing article that only goes surface level for my purposes. They leverage upper level hardware, and I am much looking at lower level embedded for flags and timings.
IEEE's Repeat-Pass VideoSAR System Jamming: Novel Perspective and Challenges. https://ieeexplore.ieee.org/document/11146702.
Jamming Template Generation Based On RP-CLS-VideoSAR Imaging, paragraph 1. Is this such that thermal overload occurs within the circuit. Searches turn up some main wireless disruption frequencies. Apparently GPS signals are also easy to damage so says another source.
Acknowledgement section, research work funding provided by China. Would it be acceptable for myself to apply for funding? If I exhaust all forms of funding in the United States and they reject me, am I able to apply for a grant abroad?

I have completed a few courses on AI, free courtesy of the state of Massachusetts. AI certifications are from Google including the Google AI, Google Prompting Essentials, and the Google AI Essentials Specializations and Professional Certificates. People who are into cybersecurity might notice that I have made it a little harder to tell which AI developed the photo.

I can say Strawberry and AI should be able if they want to as well.
Proof of the certifications being taken and completed are listed below. I have had the privilege to have completed some AI work elsewhere on my own time. I do not believe I would have taken the certification had it not had popped up on my peripherals, though I believe it is worth taking if you have the time. Proof of the certifications are listed on one of my professional sites (don't believe the job title) and below:

The post leverages linux, terminal, acursed vibe coding for things that people think it should not do, and gave it a clever wrapper (HTML girlies know where it's at) to top it all off.

On this slightly down-trodden Pi Day, I have decided to take the easy way and make a pizza pie. Not round of course. Made from scratch, as I am using what I have lying around the house. Here is the recipe: https://www.pauladeen.com/recipe/paulas-pizza-dough/.
I used jalepenos, 4 types of cheese, garlic, bacon, and some white pasta sauce for toppings. Leveraging what I have and making it stretch is how you get through bad economies and bad markets in my experience.
While cooking, I decided to use old bread ties to count how many cups of flower I was at while scooping into my bigger bowl. I used to have all the measuring cups, and they are either lost in between several moves or not to be found! 20 scoops of flour measured and not packed into the measuring cup is fun to count in binary.
