    Publishing in a more prestigious journal usually means that your work will be read by a greater number of people. The journal that a paper is published on carries weight on the CV, and it is a relevant parameter for committees reviewing a grant applicant or when evaluating an academic job applicant.

    Someone who is able to fund their own research can get away with publishing to a forum, or to some of the Arxivs without submitting to a journal. But an academic that relies on grants and benefits from collaborations is much more likely to succeed in academia if they publish in academic journals. It is not necessarily that academics want to rely on publishers, but it is often a case of either you accept and adapt to the system or you don’t thrive in it.

    It would be great to find an alternative that cuts the middle man altogether. It is not a simple matter to get researchers to contribute their high-quality work to a zero-prestige experimental system, nor is it be easy to establish a robust community-driven peer-review system that provides a filtering capacity similar to that of prestigious journals. I do hope some alternative system manages to get traction in the coming years.

  • 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.

    Some time last year I learned of an example of such a project (peerreview on GitHub):

    The goal of this project was to create an open access “Peer Review” platform:

    Peer Review is an open access, reputation based scientific publishing system that has the potential to replace the journal system with a single, community run website. It is free to publish, free to access, and the plan is to support it with donations and (eventually, hopefully) institutional support.

    It allows academic authors to submit a draft of a paper for review by peers in their field, and then to publish it for public consumption once they are ready. It allows their peers to exercise post-publish quality control of papers by voting them up or down and posting public responses.

    I just looked it up now to see how it is going… And I am a bit saddened to find out that the developer decided to stop. The author has a blog in which he wrote about the project and about why he is not so optimistic about the prospects of crowd sourced peer review anymore: , and related posts referenced therein.

    It is only one opinion, but at least it is the opinion of someone who has thought about this some time and made a real effort towards the goal, so maybe you find some value from his perspective.

    Personally, I am still optimistic about this being possible. But that’s easy for me to say as I have not invested the effort!

  • 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.
