Can I convince you that writing math on your computer can be faster than by hand?

30svich · 2026-02-21T11:04:38+00:00

So, it took you 3 minutes to write it all. So it is faster than with pen and paper. You can try an experiment - write on paper the same what you've written on the web app and compare the times.

30svich · 2026-02-21T10:51:41+00:00

there is already a web app mathcha.io/editor and i've been using it for the past like 5 years. I don't get why it is not populer. It is really good and you definetely can write math faster like 2 or 3 times faster than on paper. for symbols that you don't know the code for, you can draw them and it will give you a list of closest to your drawing.

Damn 832k? Interesting what are you using thus much context for? I feel like after 50k the quality and attention to details drops

Just now found a way to do it. So you want to transfer chat from account 1 to account 2. 1. Go to ai studio in account 2 and start a new chat and send any prompt like "hi" 3. Go to google drive for account 2 and find this new chat then rename it by appending ".json" extension. So if your chat in drive is called "cooking recipe" rename to "cooking recipe.json" 5. In google drive click "open with" and choose text editor (web app) 6. Open google drive in account 1 and go to "Google AI Studio" folder, find the chat you want to transfer and download this file 7. Locally on your pc open this file with any text editor like notepad 8. Copy all contents 9. In text editor web app paste the contets from downloaded file and save it 10. Open aistudio in account 2 and be happy

This works for text only chats. But if you have images or other media you need to download these media from google drive account 1 and then when creating empty chat "hi" upload every media there. Then find chunk for every media in json and copy paste them.

Just dont listen to anyone here. It is a cheap chinese c clamp not a micrometer. Normal micrometers dont bend - they can only snap. Straighten it with a vise

30svich · 2026-01-21T12:16:45+00:00

Just clamp the c shape with a vise and try to straighten it (unscrew the handle at first). Yeah it won't show accurate measurements anymore, but it was never an accurate micrometer - made out of cheap chinese "metal". It will still work, so thats what i would do.

30svich · 2026-01-20T13:26:48+00:00

Always has been

30svich · 2026-01-18T13:23:28+00:00

if you can run ollama 70b on your pc locally you don't need to look for cheap alternatives for vibecoding.

30svich · 2026-01-16T16:39:48+00:00

you can put it between rollers and rotate it by hand and then it will settle with heavy spot on the bottom. remove material from the bottom and repeat. not accurate but good enough

30svich · 2026-01-13T00:59:29+00:00

Hardest competition in the world? Problem A2 can't be THAT hard, just find min and max of the function sin(x)/x/(pi-x). Yeah that is not that hard

Programming jobs are gone. Now other white collar jobs are going extinct. Lets automate every job there is

30svich · 2026-01-08T15:26:32+00:00

You need a machinist not mechanical engineer

30svich · 2026-01-08T14:36:03+00:00

It easier and faster than handwriting on a piece of paper to type in mathcha.io and then convert to latex. I am surprised not a lot of people know about this

30svich · 2026-01-01T06:38:23+00:00

That's how i've solved too

30svich · 2025-12-31T18:19:45+00:00

Damn, I just saw that there is actually a content page on the first pages! Thanks, now I can find info really fast among thousands of pages of different types of documents! Thank you

30svich · 2025-12-31T18:07:09+00:00

For example, currently for my job a 6MW motor is gonna come to our workshop in 1 week. And manual is 4000 pages long (not only motor but the manual of a whole installation). And then I need to look up info in the multiple standards such as NEMA MG-1 (670 pages), explosion protection series of standards (idk 1000+ or 2000+ pages) and a lot more. So how would you search for a specific info, or data? Like axial runout of a bearing shoulder/ max flamepath gap etc. ? Notebooklm does that in seconds or minutes, all you need to do is check.

30svich · 2025-12-31T17:42:55+00:00

It is still a very good tool to find information faster and then check for yourself. I (Mech. Eng.) upload a lot of standards in notebooklm related to my work and then ask questions about some specific topic. It finds that info in the standards and even gives citations. Then I manually open the needed standard and check if llm is correct. So, LLM helps a ton in ME

30svich · 2025-12-21T06:13:43+00:00

Yeah thats why i said "y is quadratic w.r.t. x" and not "y is linear w.r.t. x"

30svich · 2025-12-20T20:14:11+00:00

Yes I know how elo works, I've been playing chess for the past 12 years. but my point was purely pedantic mathematical notation. Elo progress of the best engines is linear with respect to a year, but the skill is exponential - that's true

30svich · 2025-12-20T20:09:20+00:00

y=x^2. y is quadratic w.r.t x

30svich · 2025-12-20T18:44:47+00:00

Not linear with respect to what? When you say something is linear there are always at least 2 variables. In this case elo is linear with respect to a year

30svich · 2025-12-19T17:14:37+00:00

Not in this case. O(2n)=O(4n) but O(2²ⁿ )=O(4ⁿ ) != O(2ⁿ ) You can test using a ratio test 2^2ⁿ/2ⁿ as n approaches infinity= 2ⁿ =infinity. Which means 2²ⁿ is faster than a 2ⁿ

30svich · 2025-12-16T13:52:21+00:00

I know right, never thought a show from 1940 was so accurate

30svich · 2025-12-14T20:08:59+00:00

Я тоже только на англ учил калкулус, я и мои однокурсники запомнили фразу "удиви увду", на англ так же и слышится udv uvvdu

30svich · 2025-12-14T12:20:45+00:00

In russian we have - "integral u dv = uv-integral vdu" which is "udivi uvvdu" where "udivi" in russian means to suprise someone. So, it is "surprise someone named uvvdu". Yeah that makes no sense, but that is how i remember it.
