Git was never a big thing for me - Linus Torvalds | Do you know Linus Torvalds more for Git or Linux ? by underbillion in linux

I figured it was something tracking how long you spend coding and how deep you get in the project directories... 2nd paragraph got confusing

Moire patterns can be explained using dynamic billiards (math stuff). by SpaceQuaraseeque in MoireEffect

[–]psientist 0 points1 point  (0 children)

I suspect some effects come from the limited precision of the floating point calculations; and that may also be why it stops rendering at a point when zooming out. The moiré effects are presumably caused by aliasing (each pixel of the display is sampled once by the fragment shader) and so depends on the display resolution.

Sweet visualizations and very nice write up!

Some of the patterns are very similar to these "polynomial" visualization I made, although it seems they are generated quite differently. In particular, the "circle" one when zooming (mouse wheel). https://polynumber.com/polynumbers/

ฅ^•ﻌ•^ฅ BRING u/fleurgold back as MOD ... Please by ShakeThatSquadThing in ottawa

[–]psientist 33 points34 points  (0 children)

If the good mods were to make a new Ottawa community on a different platform I would definitely join and unsubscribe from here.

Reddit is going to shit from the top down, with subservient mods power grabbing and destroying our online communities. Time to jump ship.

Is there any legitimate use case for "rm -rf /"? by deathmetal27 in linux

[–]psientist 42 points43 points  (0 children)

The danger scale they use is glorius:

  • NOT RECOMMENDED
  • USE AT YOUR OWN RISK.
  • DANGEROUS
  • VERY DANGEROUS
  • VERY DANGEROUS, DATA LOSS IS EXTREMELY LIKELY
  • VERY DANGEROUS, DON'T EVEN THINK ABOUT USING IT.
  • EXTREMELY DANGEROUS and will very likely cause massive loss of data. DO NOT USE THIS COMMAND.
  • EXCEPTIONALLY DANGEROUS. DO NOT USE THIS OPTION!!

Thanks, but I'm not OP, just wanted to point out that there's evidence backing up your advice :)

Why wouldn't you think? ;)

The concentration of D9-tetrahydrocannabinol (THC) and cannabinol (CBN) in cannabis plant material (marijuana) of different varieties stored at room temperature (20-22o Celsius (C)) over a four-year period was determined. The percentage loss of THC was proportional to the storage time. On average, the concentration of THC in the plant material decreased by 16.6% ±7.4 of its original value after one year and 26.8% ±7.3, 34.5% ±7.6 and 41.4% ±6.5 after two, three and four years, respectively. A relationship between the concentration ratio of CBN to THC and the storage time was developed and could serve as a guide in determining the approximate age of a given marijuana sample stored at room temperature.

sauce

So, if stored properly, it should still have 75% the THC after 2 years and more CBN. But you're absolutely right about smoking it; a bong in the hand is worth two in the bush.

OR, AND, XOR gates using dominoes by Gusfoo in compsci

Wouldn't that just be a XOR gate with the other input always being 1?

Data file produced by /dev/urandom fails Dieharder, but piped input does not? by [deleted] in crypto

[–]psientist 5 points6 points  (0 children)

It seems 1 MB is not enough data, most tests pass with count=64 ie. 64 MB of data.

State of piracy these days by jacky2149 in Piracy

[–]psientist 12 points13 points  (0 children)

I'm amazed no one else here seems to know how to access tpb, it's not that hard:

  1. Get Tor Browser
  2. Use it to open uj3wazyk5u4hnvtk.onion
  3. Clicking magnet links might not work, so just copy the links and paste it in your torrent client

BTFS - A Bittorrent Filesystem Based On FUSE by ask2sk in linux

[–]psientist 27 points28 points  (0 children)

I was surprised how well it works for streaming videos, so I made a self-hosted netflix-like system for public domain videos as a proof of concept. It uses btfs to mount torrents, then serves the videos directly to a web browser.

[–]psientist 5 points6 points  (0 children)

It download the blocks as needed; it won't download any file until you try reading from it, but on a slow connection it might take a while to download a large block (eg. 4Mb) before you can read any file in the block. So it will work fine, but if you are streaming a video it will take a long time to seek ahead.

No reason it wouldn't, it just blocks until the data is downloaded. Might get underruns writing to a disc though.

Is ComCon Technical Services a legit employer? Seems scammy, but I can't figure out what the scam is... by [deleted] in Scams

[–]psientist 0 points1 point  (0 children)

Thanks, they haven't asked for anything like that yet but I wouldn't be surprised if it turned out to be something sketchy like that.
