adult greenhouse frog

baby greenhouse frog

Found many of these frogs under a wet trash bag in a back yard in Mérida, Yucatán. I made use of a handheld flash with a remote trigger for lighting, and a Sigma 105 mm as my macro lens.

These frogs do not seem to match with any of the local frogs reported in Julian C. Lee's field guide to the amphibians and reptiles of the maya world.

From a reverse image search, I mostly found images of the green house frog Eleutherodactylus planirostris. Eleutherodactylus planirostris is native to Cuba and the Bahamas, and is often introduced with plants that come from green houses in those areas. These frogs go from tadpole to frog while still inside of the egg, which explains why the baby frogs are so small.

The visual aspect, the incredibly small baby frogs, and the fact that they were found in a back yard in the city with greenhouse plants, all lead me to conclude that it is likely Eleutherodactylus planirostris.

When a website can be accessed via a clearnet and a .onion url, is there a benefit to making use of the .onion url?


Context:

I am considering pointing a ".onion" url to my instance (mander.xyz).

I did some tests with and it seems like mlmym works well with JavaScript disabled. Since JavaScript is often disabled in the tor browser, I could make the .onion url point at that front-end instead.

This would be fun to do, but I wonder if there is a practical benefit to the ".onion" url as opposed to simply accessing the clearnet url via the tor browser.

EDIT: I went ahead and created an onion URL to try out, but I would still like to know if there is an actual advantage to .onion urls:

If the timing is right, I would bring a mushroom grow bag with mushrooms sprouting.

If not... probably my radiacode gamma spectrometer and some of my radioactive items. Maybe a clock with radium painted dials and a piece of trinitite. I think that there are many different points of discussion that can be of interest to a broad audience (radioactivity, spectroscopy, electronics, US labor law story of the radium girls, nuclear explosions, background radiation.... etc). As a bonus I can bring a UV flash light and show the radium fluorescence. Adults love UV flash lights.

I think that they are referring to Paxillus involotus

It is quite an interesting mushroom. It was considered "safe to eat" for a long time, but it contains an antigen that a human's immune system can learn to attack.

The antigen is still of unknown structure but it stimulates the formation of IgG antibodies in the blood serum.

I once looked into whether this immune response builds up over many exposures, or if it is a random event that has a probability of happening for each exposure. I don't remember finding a convincing answer... If it is a random event, then mushroom could be considered a "Russian roulette" mushroom that will usually provide a nice meal, but, if unlucky, you may experience the following:

Poisoning symptoms are rapid in onset, consisting initially of vomiting, diarrhea, abdominal pain, and associated decreased blood volume. Shortly after these initial symptoms appear, hemolysis develops, resulting in reduced urine output, hemoglobin in the urine or outright absence of urine formation, and anemia. Hemolysis may lead to numerous complications including acute kidney injury, shock, acute respiratory failure, and disseminated intravascular coagulation. These complications can cause significant morbidity with fatalities having been reported.

I agree with you that this is probably unrelated to the "generally similar to humans" comment. I feel like this fantasy is a combination of the above fact mixed in with the fact that the Fungi belong to the Opisthokonts, which places them closer to animals than plants, and so they share some interesting cellular characteristics with us. This places them closer to animals than plants, but "generally similar to humans" is perhaps a bit of a stretch ^_^

But, it is just a meme about a guy being hyped about mushrooms. Hopefully people don't expect memes to be super accurate 😁

First of all, congratulations for bringing a baby girl into this world!! You must be really excited! I am very happy for you!

This looks very cool. I set up a wiki (https://ibis.mander.xyz/) and I will make an effort to populate it with some Lemmy lore and interesting science/tech 😄 Hopefully I can set some time aside and help with a tiny bit of code too.

Expatriate/expat

Maybe it is not a popular opinion. And perhaps calling it "bigotry" is too far. But I work in a different country from where I was born, and I consider myself an immigrant. I have however seen this trend of referring to educated professionals as "expats" to distinguish us from people who immigrate to escape conflicts and/or poverty. I don't agree that this distinction is necessary or valuable, and I feel uncomfortable when I am described with that term. If I am called that, I usually chuckle and let people know that I'm an immigrant!!

  • Password hashing occurs server-side. Even without removing the hashing step an admin can intercept the plaintext password during login. Use unique safe passwords.

  • An admin can intercept the jwt authentication cookie and use any account that lives in the instance.

  • Private messages are stored as plaintext in the database

  • Admins can see who upvotes/downvotes what

  • These are not things that are unique to Lemmy. This is common.

  • To avoid having to trust your admin, run an instance.

Full genome sequencing.

The price of sequencing continues to decrease as the technology evolves. I have already seen claims of under $1,000 for a full human genome. I haven't looked carefully into those claims, but I think we are around there. In some years full genomes will be so cheap to sequence that it will be routine. I want to buy one of those small Oxford Nanopore MinION sequencers in the future. I'll use it like a pokedex.

Really cool! I'm excited to learn more about you and the project!

What's the format? Should we submit questions beforehand, or will you process questions that arrive at the start time? I've never participated in an AMA 😅

We experience ourselves and our surroundings through our consciousness, and yet it is such a mysterious thing. Since we know consciousness only through our own experiences, we find it natural and easy to point out at things that make us special - like our ability to use language and our complex reasoning patterns - and then somehow extrapolate that these things that make us special are intimately connected to our ability of experiencing consciousness.

But, unless I am very mistaken, there is literally no evidence to support this hypothesis. It is a conjecture that we've made up because it is easy to believe it. We start from the position that we agree that we humans are conscious - and then other systems have to somehow prove their consciousness... Despite our inability of proving that humans experience consciousness!

Personally, I am of the view that the phenomenon of consciousness is a lot more widespread than we currently imagine. It find it hard to believe that that we are so special, and that it was necessary for humans to evolve until this magical phenomenon of "consciousness" began to take shape.

My view is: I don't like this cultural element, and I am glad that I live in a country without it. But if I am a visitor from abroad I would not resist the local culture and try to impose my own values. If I am aware of this cultural element and I dislike it, my options would be to either avoid restaurants and other tipping situations as much as I can, or simply account for the tip when making my financial decisions, and pay it.

If I live in the country then it is different, because then I am more entitled to be a driver of change. Personally, my approach would be to support businesses with explicit no-tipping policy, and to refuse receiving tips myself.

Well, good thing that you prepared well in advance and have already built a nice alternative.

Reddit is done

I am curious about why lemmy.ml is blocked in your country. Is the 'ml' domain generally blocked? Or was lemmy.ml specifically added to some block list?

A small cloud server + a domain name costs less than a Netflix subscription. The developers have taken care to package lemmy in ways that are relatively straight forward to deploy, so a dedicated person with a small amount of experience can have an instance up and running in an evening. As long as a few percentage of users are willing to pay a netflix subscription to keep a server running, the financial burden would be spread.
