This may not be a appropriate post for this community, and is not strictly web development. It is browser related, specifically qutebrowser, but i don't think the behaviour is qutebrowser specific, it may be chromium specific though, but i don't know how to test on any other browser because i hardly know js. If this is not valid for this community, please do tell.

I was writing a way to redirect other lemmy instance links to my home instance. I am basically trying to write lemmyverse.link (it's working is explained in the following issue, but essentially we just ask the instance where we want to be redirected, if they have the post, if so, they return json, which will have post_id in that instance, and we can use that.

https://github.com/RikudouSage/lemmyverse.link/issues/14

I think I have implemented that somewhat successfully, and it works for all the instances that i have tried, except lemmy.world (why could it not be some tiny instance which i could ignore). For lemmy.world, browser ui shows as if it is loading. I checked dev tools, and we do get the redirection (see the post_id change below in the attched video, and when i click that, i get redirected to correct page). It shows a red errors, but i can not find how to find errors (none of tabs show any errors).

https://envs.sh/s/NhX_dHEZh52CD1MwcXXLwg/cSI.mkv

(the video show succesful redirection for some instance, and unsucceful redirection for other)

I hope someone who knows how to do this help, I could not find anything wrong, and hence am not able to even search for errors online.

If you can go through it, please do, there are some references for some claims, if not you can go through the following ai generated summary (if it helps, it is a local llama)

The original poster (sga) expressed concerns about the practice of trimming cat nails, comparing it to declawing and suggesting that it may cause trauma for the cat. Other users (Bamboodpanda and Chairman Meow) responded that trimming cat nails is a normal and necessary practice, especially for indoor cats, to prevent overgrown nails and damage to furniture. sga argued that cat claws are an essential part of a cat’s predatory nature and that trimming them may impair their ability to hunt and defend themselves. Chairman Meow countered that cat nails are not as robust as sga suggested and that trimming them does not impair their usability. sga provided several sources suggesting that indoor cats often engage in predatory behavior outdoors, despite being fed at home. SupremeDonut responded that the sources sga provided referred to free-range and feral cats, rather than indoor house cats. sga provided additional sources to support the claim that indoor cats also engage in predatory behavior outdoors. sga also mentioned the hypothesis that some amount of injuries or exposure to allergens can be beneficial for children’s immune systems, and provided a source to support this claim.

It is somewhat of xy problem too, so please read the post for more details.

A bit about my background - I am currently doing Bachelours of Technology (last semester) from a somewhat reputed university. (If you belive in those sham rankings - it is in top 200 in world).

I want to do a doctorate (and stay in academia/research, not interested in industry). I am still not fixated on a particular research field (intersted by many things) but I have a strong inclanation towards one, so currently that only.

One option is to do phd in my current uni only, but thing is that my uni is not that great in terms of research (can be generalised to country as well to some extent) - mostly it comes down to lack of funding and lack of students interested in doing research, most people are interested in joing some or other industry.

Other option is to go abroad. Considering the current environment, my current preference would be "Europe only".

From what I know, doing a doctorate in most european schools requires masters.

Also before anybody says this - I know for doctorate, the school matters less, and a good supervisor matters more. I understand this, but I can not really find any way to find a good supervisor. Maybe it is my ignorance, but I have never really paid attention to any names, and If I staart looking up names, there are tons. Also, I don't really know how to rate people. One thing would be to find someone with my interests, and ask them, but I do not know anyone. One is to rank them by their publications, but that definitely does not feel right to me. Some people just have a easier chance to get in bigger journals. I know at the end of the day, citations do not depend much on journal, but still it does not feel right. Also, most newer profs are definitely handicapped here (because they just have not had enough time to get enough citations, or may be their research may not be justly appreciated)

Another thing is, I would prefer to do masters in the same institution in which i would be potentially doing my phd, mostly because I do not want to spend a lot of time relocating (I am lazy).

Another thing is - I would really prefer a school where there is no or low academic fees (for low, lets say 1000-1500 Euros, because that is roughly what I pay currently). I do not really want to burden my parents anymore, and not having to pay a exorbident amount would be a great help.

I have done some lookup - in europe, from what I can find, it is mostly german uni which are offering no tution fees (I know that is not a general statement, for example I checked TU Munich has my prefered interest as masters program, and also no tution fees, but there are more)

I have tried doing "interest" phd and "interest" masters and a billion results come, mostly reasearch groups - but they all seem good to me.

One way to compare is use the said "sham" rankings. I think they do a good-sh job in rough categorisation, for example if they say some school is top 10, and some school is 1000+, I would generally accept that (but I think in that sense, most people would be able to tell that, sometimes just by having a look). But how their rankings swing wildly for some schools, where nothing really changed, and also, they don't put out weights for individual components, they say they use n number of components to judge, and also claim n components have n different wieghts, but we don't know them. They also sometimes give subject/domain wise rankings, which is better, but there is still a fundamental problem - their sources for ranking, and being private ventures, potential for being swayed by "some people" is deal breaker for me. So I can not blindly depend on them. I would much rather prefer human opinion on forums. Reddit has helped to some extent - but there are definitely both sides of opinions present, and I can not compare.

Also if anybody wants to know how did i choose when I did for bachelours - well I did not choose. In our country we have a nation wide entrance exam, for our best schools, and you are alloted based on ranking in that exam. So only choice I had made was to give that exam.

I want to know both - in general - how to compare different schools/supervisors and more specific to me - what should I do (for this part, name of schools/programs would be helpful)

I had this effectively a shower thought idea - why don't we have ceramic 3d printing?

Let me clarify - before posting, I looked it up, and I could not find exactly what I was looking for. There are already commercial offereings for Clay 3D printing, but that is not forming the ceramic in situ, we are depositing what is effectively ceramic in a solvent, and drying it. What I was thinking was making the ceramic on site.

Here is a example setup

• Imagine a regular polymer 3D printing setup

• imagine instead of filament, we have a tank of Ca(OH)~2~ (calcium hydroxide, or slaked lime) (not necessarily just this, but for example, consider this combination)

• imagine we instead of droping a full thread like layer of semi-solid polymer, we form a trail of really tiny water drops

• we sprinkle in Ca(OH)~2~ onto the drops (or this step can be skipped if we can pre mix it with water, and then somehow figure how to deposit really tiny drops of what is effectively a very strong base

• now we let CO~2~ in, and form CaCO~3~

• deposit a layer to fill voids in this layer (we dropped a non continous strings of drops earlier)

• evaporate remainning water

• repeat this step until this layer is complete.

• repeat process for next layer

Now I can think of many problems here

• how to handle very strong base - maybe a tip of refractory alloys, or something like Inconnel (or Ni Cr alloys in general), or ceramic (maybe alumina) coated metal (probably cheapest, but hard to make)

• how to control solidification - we are effectively doing a solidification reaction, and growth of crystal would largely be dependant on the crystal facettes, and we would not be able to have any sharp angles. Also, we would not be able to have a very small width with this.

• surface tension of water will not allow to easily create uniform small dots - only thing I can think of is using something mechanical to hit the water droplets at tips to effectively launch tiny droplets. (Imagine shuriken (stars or blades) breaking droplet, and water landing) - still we would not have control

• how to control solidification rate in exothermic process - maybe easy, but we would need something like fans or coolant, otherwise we would form big drops at a spot due increased nucleation rate

• how to introduce CO~2~ fast enough - we would have to have a very strong CO~2~ environment, somehow not let it solidify at tip. Also this reaction is very slow (maybe that is only the case at bulk solidification). Maybe the whole process would be very slow

Does this process already exist? If it does - any resources related to it would be helpful. If not, Why? Is it because we have not been able to solve the issues I listed, something I did not list? Would this be practical (economically)? I can definitely see both artistic and engineering use cases, and both of those can allow some big budgets.

Lets submit a India entry - !lemmyvision@jlai.lu

We will submit a song (by replying to this post) - and others should vote (upvote or downvote) any existing submission they would like to too - the most upvoted song across all three India communities (listed below) will be considered as our submission. Song requirement is basically - Something released in last 1 year (basically Jan 2024 to March 2025) which is openly accessible (that is not paywalled, so anything on youtube works, and so does non premium spotify, patreon, etc. stuff)

Hey everyone!

I hope you’ve had a wonderful year and are ready to discover new music, because the Lemmyvision song contest return now for its second edition! For those not in the loop, read below to learn more about this Lemmy Event:

TL;DR

From right now and until April 1st, discuss with your country’s community on Lemmy about which song to send to the contest. Submit the song in this community by makign a new thread. On April 2nd, voting will begin, where you will rank your favourite songs in a form. Any song not submitted by this date will not be featured. On April 8th, results of everyone’s favourite songs will be published. You can use !lemmyvision@jlai.lu for any question, this will be the community for updates and results, make sure to subscribe if you’d like to stay in the loop. What is Lemmyvision?

Lemmyvision is inspired from Eureddision (itself a reenactment of the Eurovision song contest) which was held on r/europe some years ago, and based on the participation of national communities / instances and the delicate musical taste of their members (you!).

Every country/community is welcome to participate! The contest follows the rule of “national languages only” but regional languages are welcome too, if your community would like to feature a song in a regional language of your country, that’s awesome. The aim is to promote different languages and cultures from around the world, to share more between our online communities across Lemmy, and discover songs from lesser known artists.

Last year, an exception was made for the programming.dev Lemmy community to participate by sending a song related to their main interest (they sent a video game soundtrack), if your community does not represent a specific country or language but wants to participate by sending a song related to your instance center of interest, you’re welcome to do so! For example, lemmy.blahaj.zone could send a song composed by a Queer person!

How it works:

This post, and the !lemmyvision@jlai.lu community will be open until April 1st, and I will start promoting the event on various instances and communities. Lemmy communities who want to participate have the responsibility to gather its members and vote on a single song to send for the contest. On April 2nd, the songs will be locked in. A playlist will be created to allow you to listen to all of the submitted songs, and communities will be invited to vote on their favourite. The voting is estimated to last for about a week. On April 8th the results will be published, with a ranking of everyone’s favourite songs!

I don’t expect countries with a “small” population to be accurately represented on Lemmy, so no worries if you don’t have a community and are just a small group of people, or if your country is not even on Lemmy but another platform (Kbin and whatnot), I can make exceptions, just reach out!

Regional languages are welcome as well! Basque, Welsh, Cherokee… You’re welcome to promote a non official language instead!

Song submission:

Each Lemmy community is responsible for their own organization. Only one (1) song is to be sent to represent your community. If the song contains vocals then it must be in (one of) the official language(s) of your choice, or a regional language of your choice. Songs must have been released within the last year (after January 1st, 2024). Songs must not be international hits[1]. Submit your songs in their own thread in this community Verification will just require a link to the discussion thread created within your community, to ensure it’s a community (not a single person’s) decision. [1] this is to prevent drama that happened in the past on Reddit, where Germany sent a Rammstein song and obviously won. It’s up to my own appreciation of what international hit means, because it’s hard to measure (metrics on youtube or spotify aren’t the same), but I’m pretty lenient, just ask me if you’re not sure, better to discuss it than argue

Voting:

Voting will be done through a form created on tally.so. I will set up the form near the end of the month, and share it in a new announcement post when the time has come. If you’re worried about privacy, there will be no questions about personal data, and last year I deleted the form and its results a week after the event was done. On Federation:

I don’t discriminate based on instances, if your account is not on the same instance as your community, that’s totally fine. Additionally, if you’re on another Fediverse/Activitypub platform and would like to participate, and you’re able to federate with your representing Lemmy community, you’re welcome to join us, I’d just like to keep organization within Lemmy so it’s easier to track participations.

Would you like to help?

Last year went really well, and I managed to handle the thing alone. Programming.dev even helped with setting up the playlist! If you’d like to help in any way, please feel free to reach out, I’d love to have as many people as possible involved!!

Cheers!
