Testing mastodon federation
Hello! Does this work?

Interestingly, I got this notification just now! But it does work :-)

Hello! I don’t speak much german yet, but I would be happy if you would allow federation with this instance (mander.xyz)!

I also noticed that you are federating with and linked to pleroma.schuerz.at. What does this mean? Is there a way for lemmy to communicate with a pleroma instance via activity pub?

As a scientist, for me this gap was bridged by doing a master’s and PhD.

In my field, learning involves performing experiments using very expensive equipment and potentially very expensive failures. We need to spend a lot of time doing things that will build our own value (like reading papers and manuals and performing failed experiments) without necessarily producing a valuable output in the short term. It is difficult to do these things on our own without help and financial support from academia or industry. One would need to be in a very privileged position to be able to bridge the gap on their own.

I moved to the Netherlands for my studies from a place with zero cycle lanes, and my answer is absolutely yes. I think that cities should should have more cycle lanes!!

I am testing out Obsidian at the moment and I am liking it. I am still trying to figure out what the best way to sync between devices. At the moment I have found this script and Syncthing, but I am still only using it locally. Their phone app is still in closed beta, so probably not the best choice if you want to access notes from your phone.

Cool, a lot of these I don’t know about! I always load files using split screen, I didn’t know that I could also keep files open in the buffer and move through them with :bn/:bp. This will be very useful.

I am not sure what level I fit in because my regularly used skills are all over the list. I have not managed to get used to “hjkl”, so that might make place low in the eyes of true Vim masters. I still manage to look like a wizard to my co-workers though.

Thanks, I will check these out!

That’s a good point. I haven’t gotten to ‘de-googling’ my Android and I do use Chrome in my phone. I feel silly now for overlooking that!

That sounds abusive.

In the report linked above there is a section on Plant-Closing Threats. They point out the following:

Employers recognize the value that plant-closing threats add to an overall anti-union strategy, and they frequently issue such threats even when they do not intend to carry them out. Bronfenbrenner (1997) found that half of all employers involved in union organizing campaigns nationally issued threats to close all or part of their operations should the union be victorious. Just three percent actually followed through on these threats after workers voted in favor of union representation. (Bronfenbrenner 2000)

There is also a section that discusses the legality of such anti-union strategy:

Most Employer Tactics Are Considered Legal or Difficult to Prove as “Unfair”

At first glance, many of the tactics that employers use appear to violate the law. For example, the threat of company closings or relocations is one of the most common anti-union tactics used during organizing campaigns. The following are examples from the CRC Survey of the ways in which employers delivered the threat that avoid explicitly connecting the closure of the facility to employees’ decision to join or vote for the union or engage in protected activity:

• “I can close this company if I want to.”

• "I might have to close [the company] because we don’t have money. I might shut down [the company] and re-open it under a different name.”

• "The company is losing money and can’t compete with a union in place.”

• "The company next door closed because of a union. A lot of companies are closing down or leaving the U.S. because of the unions.”

• “Unions make our business unviable”

With a culture like this it makes sense that they would want to protect their rights to own a gun. If receiving their first gun is a special milestone during their youth, and the person grows up shooting guns with family and friends, I can see how guns can become part someone’s identity.

Most of my life I have lived in countries were guns are banned, so from my perspective it is easy to say “No, of course that I don’t want it to be easier for the people around me to own guns!”. But I can appreciate that it is different when you talk about removing a freedom that is accessible at the moment.

Huh, I wouldn’t have guessed such a small share for Firefox.

What are some valid reasons for workers to vote against unionizing?

I did find this report on the topic, which I will try to look at later. I am pretty ignorant about the topic of unions.

Federation is currently off for that instance, is that on purpose?

It can be turned on by adding the following to the lemmy.hjson file:

federation: {
enabled: true
tls_enabled: true
# allowed_instances: lemmy.ml,other_instances

If you don’t uncomment #allowed_instances, then you have open federation.

I prefer bow and arrow in the shooting range and a camera for wild animals.

As for control. I am sure that there are people who have very good reasons for owning a gun, and I do not like blanket bans. I am in favor of a process that allows a citizen to obtain a gun legally. However, it is my understanding that it is easier to obtain a gun than a diving certificate in the US, and that to me seems like an incredibly low bar.

When you do delete your account you have 30 days to restore it. I think that their reasoning behind this is that it gives you time to regret your decision and come back.

But you can use the psychology of this feature in a different way: Delete your account while giving yourself explicit permission to restore it if you need it within the next 30 days. I did this and, well, it’s truly deleted now :-)

You can also export all of your photos to another cloud storage service automatically.

I find particle physics to be quite intimidating with its infinite number of paths involving a zoo of particles doing an infinite number of things, but this is clear! Very cool, thanks for sharing

There is a protein in bacteria called a "tryptophan repressor". This protein can change its conformation when it binds to tryptophan. Tryptophan is structurally similar to auxin, which is a very important plant hormone. The researchers engineered a modified the tryptophan receptor that will bind reversibly auxin instead of tryptophan. They also engineered it such that it will produce a specific type of fluorescence only when auxin is bound to the protein. This is done by using this shape-changing protein as a bridge between two different fluorescent proteins, one which acts as a donor and the other as an acceptor. Energy transfer from the donor to the receptor can only occur when the protein bridge is in the conformation elicited by auxin binding. The end result is a protein which, when excited with light, will produce a different light output depending on the local concentration of auxin. By adding this new gene to a plant one is able to visualize the concentration of auxin directly using a microscope.

Mod logs should be public by default on reddit so that there can be more transparency about issues like this…

What’s the article that they are banning?

It is really cool to be able to witness how the Fediverse is being built in real time. I am excited to see how the different projects become intertwined in the coming years! I think that this is a step in the right direction for the future of the internet, and I have high hopes.

It works. I can see the Accept events and the new posts are fetched.

The problem was that RUST_LOG=verbose does not print anything. I had to set it to RUST_LOG=debug to see the activities.

Thanks. I couldn’t figure out where these activity logs are stored. I checked the nginx logs and ‘docker-compose logs -f lemmy lemmy-ui pictrs’ with RUST_LOG set to verbose. I will read more carefully the docs tomorrow.

Alright, thanks!

I have done the following:

  • Clicked “remove”, then “restore” on all of the communities.
  • Made a new account and subscribed to all of the lemmy.ml communities

I will see if this resolves it tomorrow. I am not sure if clicking remove/restore is enough to submit a new follow request.


It appears like the communities that I followed before I was in the allow-list will not be fetched automatically. Is there a way for me to jump start the automatic requests again?

As an example, this announcement was not fetched: https://lemmy.ml/post/59511 even thought there are 3 subscribed users in the instance.

[Burns, John A., Ryan Kerney, and Solange Duhamel. "Heterotrophic carbon fixation in a salamander-alga symbiosis." Frontiers in microbiology 11 (2020): 1815.](https://www.frontiersin.org/articles/10.3389/fmicb.2020.01815/full) **Abstract** The unique symbiosis between a vertebrate salamander, Ambystoma maculatum, and unicellular green alga, Oophila amblystomatis, involves multiple modes of interaction. These include an ectosymbiotic interaction where the alga colonizes the egg capsule, and an intracellular interaction where the alga enters tissues and cells of the salamander. One common interaction in mutualist photosymbioses is the transfer of photosynthate from the algal symbiont to the host animal. In the A. maculatum–O. amblystomatis interaction, there is conflicting evidence regarding whether the algae in the egg capsule transfer chemical energy captured during photosynthesis to the developing salamander embryo. In experiments where we took care to separate the carbon fixation contributions of the salamander embryo and algal symbionts, we show that inorganic carbon fixed by A. maculatum embryos reaches 2% of the inorganic carbon fixed by O. amblystomatis algae within an egg capsule after 2 h in the light. After 2 h in the dark, inorganic carbon fixed by A. maculatum embryos is 800% of the carbon fixed by O. amblystomatis algae within an egg capsule. Using photosynthesis inhibitors, we show that A. maculatum embryos and O. amblystomatis algae compete for available inorganic carbon within the egg capsule environment. Our results confirm earlier studies suggesting a role of heterotrophic carbon fixation during vertebrate embryonic development. Our results also show that the considerable capacity of developing A. maculatum embryos for inorganic carbon fixation precludes our ability to distinguish any minor role of photosynthetically transferred carbon from algal symbionts to host salamanders using bicarbonate introduced to the egg system as a marker.

Journal of Experimental Biology, 214(2), 303-311.](https://jeb.biologists.org/content/jexbio/214/2/303.full.pdf) **Summary** Symbiotic animals containing green photobionts challenge the common perception that only plants are capable of capturing the sun’s rays and converting them into biological energy through photoautotrophic CO~2~ fixation (photosynthesis). ‘Solar-powered’ sacoglossan molluscs, or sea slugs, have taken this type of symbiotic association one step further by solely harboring the photosynthetic organelle, the plastid (=chloroplast). One such sea slug, Elysia chlorotica, lives as a ‘plant’ when provided with only light and air as a result of acquiring plastids during feeding on its algal prey Vaucheria litorea. The captured plastids (kleptoplasts) are retained intracellularly in cells lining the digestive diverticula of the sea slug, a phenomenon sometimes referred to as kleptoplasty. Photosynthesis by the plastids provides E. chlorotica with energy and fixed carbon for its entire lifespan of~10 months. The plastids are not transmitted vertically (i.e. are absent in eggs) and do not undergo division in the sea slug.However, de novo protein synthesis continues, including plastid- and nuclear-encoded plastid-targeted proteins, despite the apparent absence of algal nuclei. Here we discuss current data and provide hypotheses to explain how long-term photosynthetic activity is maintained by the kleptoplasts. This fascinating ‘green animal’ provides a unique model to study the evolution of photosynthesis in a multicellular heterotrophic organism.
