Before beginning, I know this is not apprpriate question, and there may be better places to ask these questions. I also know that I as a mod am kinda abusing my powers 9not pinning the post, but still breaking the 1 important rule - to post a uplifting news, and this post is neither upliftiing nor a news. I also do not know how it is decided in other communities, I am a relatively new mod, so I do not know how to act in certain situations. But by the powers that have been vested to me by the gods (previous mods), I want to ask a lot of questions.

Also for the time being, lets say the world has 2 major groups, martians, and venusians, there are other minority groups too, but if funded govts can not bother to listen to them, how can i, a under paid corrupt mod do that. (/s just in case people do not get it).

What I am basically asking is, is please help me make a 'constitution' (for the galactic rulings, obviously) on how should I (or maybe others if they choose to accept it) moderate, certain galaxy.

More seriously, please help discuss democratically, what should be the rules. To you questions may seem to have obvious answers, they did to me too, but what was not obvious, that different people have different obvious things (mind blown /s). And you all will get a chance to be "immortalized" by getting your name in the constitution drafting committee.

• What deserves a deletion of content (a comment or a post)?

-> my current understanding -> anything that breaks obvious rules. Lets say a martian, non sarcastically says - all venusianns are morons, illeterate wild animals who do not deserve to live. I would consider this as hate speech, and delete it. If someone posts something nsfw, but does not mark it appropriately, i should delete it. But what if someone posts something stupid - lets say someone thinks venusians have seven legs, when they actually have 4, and say, i want all 7 legged venusians to die. What should i do - should i upvote it, considering it is a attempt at humor, and support them, or delete it since they are still killing "hypothetical" venusians, or ignore them (that is what i have been doing right now for some reports)

• what deserves a ban?

-> similar to prior, so not explaining any further. Sometime back, i had a discussion with another mod, that we should have a strike system - something like, post hate speech 3 times, or something alike, then we ban, because you were given ample chances to figure out that you are doing something wrong (there comments would still be deleted, they would still get the downvote beating, just not a instant ban)

these questions were general, and not community specific, but following are

there are going to be lots of situations, to which you have to vote yes or no, is it uplifting or not (you are welcome to write 20 para replies too, but atleast 1 letter is required, something like 1 y, 2 n)

1. a female dog gave birth to ten little cubs

2a) cure to cancer has been found, and the researchers have patented it, and selling it for 1 million usd (for each patient) (and i know there is no 1 single cure to cancer, consider a hypothetical situation)

2b) cure to cancer has been found, and they make it free for all

3a) linux market share grows by 5 times, used by 30% of desktop users

3b) microsoft windows is now open source

3c) apple makes all their hardware designs open

Also, for the following part - any resemblence to reality is purely coincedental and unintended, i do not even live in mars or venus to know much about their politics. 4) (this question requires context) - We all know about the martian leader, he is currently leading everyone, some martians love him, others are ok with him, but he absolutely hates all venusians, and does not even acknowledge existence of saturnians, and calls them confused folk (because saturnians wear rings on them). He lies, he robs, he takes away the very last saved bite you keep while eating the food (the best bite™).

4a) the martian leader is defeated in a peaceful manner

4b) the martian leader has been taken down in a millitary coup

4c1) people march to martian leaders door, and he leaves under pressure

4c2) people march to martian leaders door, and he leaves after a bit of riot (a "few" people become "martyrs")

4d) the martian leader today opened amusement park

4e) the martian leader finds cure to cancer, and makes it free

4f1) martian leader is sad because his house has been a lot less "dusty" lately (he loves sand, because it coarse, rough, and gets everywhere)

4f2) martian leader is sad because his house has been a lot more "dusty" lately (he hates sand, because it coarse, rough, and gets everywhere)

4g) he is sad because his dog died

4f) he is sad because his business is making less profits.

I will not reveal my answers here, not to bias you people, but i would leave my general strategy in the spoilers section below

Many people might already be knowing this, for example people who use custom keyboard layouts, or people using different keyboard layouts, other than US, which most manufacturers and operating system and desktop environmnets use as default.

Most of my applications use vi like bindings, so pressing shift + ; to get : was a bit annoying, and so i was trying to find a way to swap them, and while doing so, I added most of greek alphabet, makes my technical writing a bit more easier (instead of doing $alpha$, I can do alt + a to get $α$), If you use TeX, then you can use #XeTeX to enter unicode, I use Typst, so I can directly use them, and they are used appropriately in text and equation mode. This also is helpful if your notes system does not have some math mode rendering (like plain markdown, without any katex).

If you are multilingual, but don't write much in the other language, this approach works well, if you write comparable amount in both languages, then you should consider setting a keyboard shortcut in you DE/WM config to switch the keyboard layouts

The following procedure is linux specific (or maybe other posix systems too, if they use xkb to manage keyboard stuff (this also works on wayland)), but I am sure windows and macos will have something similar (though i have not bothered to check for it, sorry for that). This does not work as a daemon sitting in between, this is using the standard way to modiify keyboard layout.

You can start by making a file like the following, and you can start with /usr/share/X11/xkb/symbols/us (or the base language of your choice, for most european language layouts, base is /usr/share/X11/xkb/symbols/latin). You have to save it in the /usr/share/X11/xkb/symbols/ directory (in my case, my original file is in config dir, and I have symlinked it to /usr/share/X11/xkb/symbols/us-custom). For list of valid symbols (most of unicode, the thing we want is the correct names) please refer /usr/include/X11/keysymdef.h. You can choose what modifier you want to use with include "level3(ralt_switch)" - I am using right alt as the third modifier, so to get the third layer, I go alt + <key>, for 4th layer, mod3 + shift + <key>. Then you can set to use this custom symbol map in your DE/WM config, in my case I have added xkb_layout "us-custom" in my sway config (for input keyboard).

// parent system is US, with a lot of greek sybols appended, and some more
// ; -> :, : -> ; - mostly for vim modes (easier to do : now)

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.
