  • There is a bit of humor and a bit of truth. I don’t have a garden and so when I was looking into whether it was possible to grow a pumpkin in a pot, most of what I found stated that the pumpkins need a lot of ground to have a strong and healthy root system, and a lot of sun, and so it is not recommended to grow them indoors. I thought that the plant would begin to grow but at some point the pot would not be able to sustain the root system and the plant would die. This has happened to me with many trees that I try to grow indoors - most recently my tamarind trees. They look perfectly healthy and then drop dead. Well, I am not certain of why the trees die but I suspect their roots rot.

    But the humor is that I still don’t think it is a good idea to grow this plant indoors. It has taken over a lot of space! My original plan was to prune it and keep it small, but I noticed that even the farthest leaves are able to pull moisture from the pot with no problem, and so I am letting the plant grow to see what happens.


  • The sensors are from AZDelivery, these ones. They are connected to an arduino nano which reads the capacitance values and sends them over to a raspberry pi 5. The raspberry pi 5 is connected to a few other sensors (CO2, particle counter, air humidity and temperature all from Sensirion), and there is a 7-inch raspberry pi display that the pi writes images to. I was making a home air quality station but I decided to place everything around the pumpkin instead for now, to see if I could get something interesting out of that. But, so far most of them have not been practically useful.


  • I did not know of the term “open washing” before reading this article. Unfortunately it does seem like the pending EU legislation on AI has created a strong incentive for companies to do their best to dilute the term and benefit from the regulations.

    There are some paragraphs in the article that illustrate the point nicely:

    In 2024, the AI landscape will be shaken up by the EU’s AI Act, the world’s first comprehensive AI law, with a projected impact on science and society comparable to GDPR. Fostering open source driven innovation is one of the aims of this legislation. This means it will be putting legal weight on the term “open source”, creating only stronger incentives for lobbying operations driven by corporate interests to water down its definition.

    […] Under the latest version of the Act, providers of AI models “under a free and open licence” are exempted from the requirement to “draw up and keep up-to-date the technical documentation of the model, including its training and testing process and the results of its evaluation, which shall contain, at a minimum, the elements set out in Annex IXa” (Article 52c:1a). Instead, they would face a much vaguer requirement to “draw up and make publicly available a sufficiently detailed summary about the content used for training of the general-purpose AI model according to a template provided by the AI Office” (Article 52c:1d).

    If this exemption or one like it stays in place, it will have two important effects: (i) attaining open source status becomes highly attractive to any generative AI provider, as it provides a way to escape some of the most onerous requirements of technical documentation and the attendant scientific and legal scrutiny; (ii) an as-yet unspecified template (and the AI Office managing it) will become the focus of intense lobbying efforts from multiple stakeholders (e.g., [12]). Figuring out what constitutes a “sufficiently detailed summary” will literally become a million dollar question.

    Thank you for pointing out Grayjay, I had not heard of it. I will look into it.



  • In the case of tempeh keeping the right ambient temperature (~30) and adding a bit of vinegar to the beans is the best way I have experienced to make it grow fast and healthy. The CO2 I only measure to check for stale air. The tempeh fungus breathes in oxygen and exhales CO2, and if you have a lot of tempeh in a small incubator the CO2 can get too high.

    In some techniques for mushroom growing, the mycelium is grown inside of a tub. The fungus exhales CO2 into the closed tub and inhibits this high CO2 condition inhibits fruiting. The fruiting stage can be stimulated by using a fan to push out the CO2. In the case of tempeh one can surround the tempeh with fresh air to stimulate the tempeh to produce spores, which can then be ground with white rice to create a powder to inoculate a lot more tempeh.




  • My plan is to remove the petals from the freshest male flower available and rub that directly.

    I store the previous set of male flowers in a cup with a bit of water in the fridge :

    If I don’t pick a male flower, the next day it looks like this:

    I did this in case that the male flowers would stop coming out when the females came. But I think my worry was not warranted… because the plant is swarming with male flowers. That’s why I have begun cooking them.

    I am still not sure of whether I will pollinate a single flower to try to grow a large pumpkin, or if I will go for multiple pumpkins.


  • The bottle is a carbon dioxide tank. It is connected to a regulator that can open/close the valve to let CO2 out. During the day it brings the CO2 level under the leaves to around 800 - 1000 parts per million (ppm). Usually the level in the air is closer to 400 - 500 ppm, and fast growing plants can grow faster with some extra CO2 in the air to build into sugars during photosynthesis. At least in theory… For me it is an experiment in CO2 regulation as I have measured and decreased CO2 levels in the past (when growing mushrooms and tempeh) but I had never actively delivered it, so I thought this would be a good opportunity to learn.

    It turns out pumpkin flowers are very fragrant, and the odor is very pleasant, but I am not good at describing smells with words, sorry… To me it smells like a mixture of a rhododendron flower and a pumpkin. I recently went to a wedding in which they served ricotta stuffed zuccini flowers (very similar flowers) and the cook clearly knew what she was doing, in that case the zuccini flowers still had some of the fragrance and this made the dish taste very special. In my attempt I filled the flowers with some curry rice and then pan-seared them in butter, and all the fragrance went away in the process. So the flower was just a vessel with the soft texture of a petal and the taste of browned butter. I did not succeed in keeping any flower flavor. It was a quick-and-dirty experiment… I would like to learn more about cooking with flowers while keeping some flavor.









  • Search engines like google aggregate data from multiple sites. I may want to download a datasheet for an electronic component, find an answer to a technical question, find a language learning course site, or look for museums in my area.

    Usually I make specific searches with very specific conditions, so I tend to get few and relevant results. I think search engines have their place.




  • I ordered four of the simpler devices this weekend (LilyGO T3-S3 LoRa 868MHz - SX1262) and I have been reading about antennas.

    Since I live in a city I am not super optimistic about the range. But I am still very curious about the concept, and I would love to be surprised.

    After doing some search about antennas, I have decided to test the following combination:

    I also have a vector network analyzer (LiteVNA) that can be used for checking antennas, so I will also try to build some antennas myself. I doubt that my custom antennas will approach the performance of the professional ones… But I just find it such a cool concept.

    Have you already gotten to play with it? What is your experience so far?

    Sure.

    If I make my own AI image generator and create a nice image with it, or use some AI engine that gives me full ownership of the output, I can choose to share it online with whatever license I want to share it with. I don’t see why the regular copyright rules for digital images and photographs would not hold… If someone shares their AI creation online and wants others to share with attribution, or not share at all, what is wrong with that?

    I can take a ton of photos of objects with my phone, upload them to Flickr, and they are all copyrighted. That doesn’t mean that other’s can simply take similar photos if they wish to do so. The same with AI. One can decide whether to share with attribution, pay someone to let them use it, or to generate the image themselves using AI. It does not seem like a problem to me.
