you can create a python virtual environment, and you do not even have to install python for that. you can install python in a user only mode, and then create a virtual environment (these can be made anywhere, so for example, your downloads or documents folder(assuming you are allowed to access these folders, you usually do)), script would have to be modefied a bit, but still doable. In case you need help for this, feel free to reply/message

In India, Punjab Haryana side (north west near pakistan border) were traditionally the bread baskets. But after a crop failures and droughts in 1960s and in 70s, they were experimented here and they were successful - a gree revolution for 10 or so years. But these varieties were very water intensive, and seeing the yields, most farmers just continously year on year did atleast 2 ccrops a year (a winter one (wheat) and a summer (rice)). This made the lands a lot less productive and many parts of the land since then have nearly become barren. 2 crops per year were normal, but it usually was never this intensivem and natural processes to restore the land (artificial or natural fertilisers, or burning parts of previes crops, or tilling) were just not effective. This lead to reduction in output, and today, a lot of youth just can not do farming, either because they do not want to (they have seen/heard of hard times from parents, or just do not have good land left to farming. This is also one of the reasons why a lot of punjabi-haryanvi diaspora is now outside India - many students just did not see a future here, and if their parents had some money from the good times, they sent their children abroad (us and canada makorly).

The intention to improve crop yield was right, but the implementation went wrong, and consequences were not great. We did not have a major famine since. Many other states took the job of producing these crops (either they partially adopted the newer seeds, or just had external investments, and used older stuff in a less intensive manner), but atleast the punjab side region lost a lot.

What I meant was for example, if someone is weak in, let’s say, english, but understands their shit, then they conduct their research however they do, and then have some llm translate it. that is a valid use case to me.

Most research papers are written in English, if you need international cites, collaboration or accolades. A person may even speak english but it is not good enough, or they spell bad. But then the llm is purely a translator/grammar checker.

But there are people who use it to do the latter, use it to generate stuff, and that is bad imo

others have given pretty good picture of what you have to do, but you can also do this in some other language, for example in binary, or ascii, and then reduce the font size to something close to 1 pixel. the actual text of pdf is stored in seperate xml tags. Plus you can also write it simply in plain text anywhere near margin of page (no need to do color or size shenanigans) and simply crop pdf out. Cropping of pdf does not remove the stuff, just hides it. Unless you rasterise pdf afterwards and then submit, the stuff is simply there with no special amount of work required.

that someone else in the chain of custody of my work decided to do the same, and suddenly this is attached to my name permanently.

sadly, that is the case.

The only useful application for me currently is some amount of translation work, or using it to check my grammar or check if I am appropriately coming across (formal, or informal)
⁨Comment⁩ on ⁨you miss all the shots you don't take⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:
that could be the case. but what I have seen my younger peers do is use these llms to “read” the papers, and only use it’s summaries as the source. In that case, it is definitely not good.
⁨Comment⁩ on ⁨you miss all the shots you don't take⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:
you can do that if you do not have integrity. but i can kinda get their perspective - you want people to cite you, or read your papers, so you can be better funded. The system is almost set to be gamed

⁨Comment⁩ on ⁨you miss all the shots you don't take⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:
often this stuff is added as white text (as in, blends with backround), and also possibly placed behind another container, such that manual selection is hard/not possible. So even if someone reads the paper, they will not read this.
⁨Comment⁩ on ⁨pHun⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:
I know this is a meme, but in case someone is interested, we usually do not want to use strong acids/bases to maintain buffers, instead, weaker acids (for eg, acetic acid), weaker bases (nh4oh), or their correponding weak-strong salt pair, or if it is really close to 7, then weak-weak, weakly dissociating salts (likr (nh4)2 co3).

I am probably forgetting the proper names for this, but idea is that waker acids/bases do not dissociate completely. for example, iirc, nh4oh is something close to 9-10, so if you want a basic buffer, then you use nh4oh in bulk to get close to required absolute amount of oh- ion concentration (maybe, because you want some reaction to happen in proper stoichiometric ratios), and for fine tuning, use very low concentration of stronger acid/base (depending on the fact that your target is above or below the value of bulk). stronger acids/bases almost immediately completely ionise. for example, i want to make something like 8.5, then i start with nh40h with 9, and slowly add hcl to reduce ph. with this, you make nh40h + hcl -> nh4cl + h2o. this nh4cl, is now acting as weakely dissociating. this reaction is also reversible. around the equillibrium ph, if you add more h+, then reaction goes forward. but simply by adding more water (or diluting), you can reverse this. with salt like nacl(nacl + h2o -> na+ + cl-) , they will practically never recombine, and you can not use this to your advantage.

the actual salt/acid/base to be used will also depend on solubility of present ions, miscibility, organic or non organic (in this context, organic means carbon related molecules)

this is regardless of that. The meme explains it a bit wierdly, but we start with 17 squares, and try to find most efficient packing, and outer square’s size is determined by this packing.
⁨Comment⁩ on ⁨Peasants⁩ ⁨⁨3⁩ ⁨weeks⁩ ago⁩:
I have a script which fetches bib entries for pdfs, and then renames it to my prefered format (names of author (no more than 2) - name of paper).

in case you are interested
```
#!/usr/bin/env sh

newnamefn(){
	bib="$(pdf2bib "$1")"
	name="$(echo "$bib" | grep "title = " | cut -d'{' -f 2 | cut -d'{' -f 1 )"
	authors=$(echo "$bib" | grep "author = " | cut -d'{' -f 2 | cut -d'{' -f 1  | sed -z 's/\ and\ /\n/g' | head -n 2 | tr '\n' ' ')
	echo "$authors-$name" | detox --inline
}

for i in "$@" ; do 
	newname="$(newnamefn "$i")" 
	mv "$i" "${i%/*}/$newname".pdf
done
```
detox --inline is just a utility which makes the file names shell friendly (removes special characters and spaces), but that is optional. Also, technically the newnamefn is what does all of the job, and below is just a loop to iterate on all files that are given as input like script file1 “file2” file3, where file2 had some special characters, so enclosed in “” quotes. you can also translate it to python, then you would not even require sed and grep (you can just get output in json-esque format). I have a small keybinding in my file manager, which renames all selected files, so I do not have to spend any amount of my mind

you can make it work in any os (maybe use some llm for it), you just have to install pdf2bib

⁨Comment⁩ on ⁨Material scientist wet dream⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:
most solids and liquids are practically incompressible (when comparing with gasses). there is a relationship between bulk compressibility, shear stress and youngs modulus for solids, which can be extended for liquids. It does not work for gasses

⁨Comment⁩ on ⁨How are roundabouts made?⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Well it depnds on what amount of cost you want to put in, and how are you making the roundabout, and are you going to put something on it, and essentially wht budgets you have. Where I live, we almost always have some statues or soemthing put on them.

They are made with essentially make shift compasses where I live. This is what is done for a roundabout of radius, lets say in ball park of 5-10 m. Initially marking is done (this is simply done by measuring out a tape of desired radius, and holding wwhen end at center, and other person revolvinng around it, and laying down something - could be simple as white chalk, or use jackhammer to make actual indents to ground, or lay down some bricks) This will serve as guide for curve, and any further curved elements could be made by just maintaining a constant distance from this circumference. Then the interior is usually dug to lay a foundation for whatever you put on it (could be as simple as excavating, and just plastering, but that is still expensive, often manually digging and then laying a firm dirt layer is enough). then it is covered with something (could be custom designed pizza slice shaped stone or marble wedges, but usually just bricks or cinderblocks). While making, we do not really make a great curved edge, and just make a n-gon, where n can be 20 or 50 or 100. This is simpler because straight edged bricks are cheaps, and you can lay them vertical, filling the gaps with plaster. The depending on your budget, you could get great finishing, again done with applying plaster, but this time, excess is applied, and some is removed, so we get a curved edge. Now you mostly have the exterior ready. On the top, you could have marble or stone, which can be grinded to match the curved edge, or it could be a thin plaster layer, which will take the shape of boundary.

⁨Comment⁩ on ⁨Damn⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
in simplification, you could derive that curvature of the orbit is basically the force between objects, with radius, from the centre of mass. Once you know curvature at a point, you ca define a series of curves fitting, and substitute with other postions to find all constants. And what is curvature? you can find online, that curvature is just a function of second order derivative, and you just have to solve a second degree differential equation.
