01:41 | <&McMartin> | Technically breaks the Shellshock record but I do not count it. |
02:50 | <&Reiver> | the what |
03:05 | <&McMartin> | Shellshock: a vulnerability in bash, a program used worldwide and whose source code is published freely |
03:05 | <&McMartin> | And which lay there undetected by defenders and attackers alike for 25 years |

09:27 | <@TheWatcher> | "this vulnerability has no real-world implications". Glad they noted that. |

23:02 | <&[R]> | https://i.imgur.com/JlqSFnd.jpg <-- dubious |
23:04 | <&McMartin> | Let's see here |
23:04 | <&McMartin> | 6% of 50 = 6 * .01 * 50 |
23:04 | <&McMartin> | 50% of 6 = 50 * .01 * 6 |
23:04 | <&McMartin> | ... as long as multiplication is commutative I think you're good? |
23:04 | < abudhabi_> | It's not necessarily easier. |
23:05 | <&McMartin> | You pick the easier one when doing mnemonics |
23:06 | <&Reiver> | The statement is factually true. It is not always useful, but if you notice either number is "Oh hey, that one is an easy percentage to do", it can prove handy. |
23:06 | <&Reiver> | Still won't save you from 17% of 23 or anything, but it's the sort of thing where "Hey guys, some days you'll realise there's an easier way around and the wisdom costs you little" sooo |
23:17 | | Kindamoody is now known as Kindamoody[zZz] |
23:18 | <&[R]> | Fair enough |
23:19 | <&[R]> | TIL, thanks! |
23:20 | <&McMartin> | Yeah, if your dubious was "I don't think this works in the general case" rather than "I don't think this makes it easier in the general case", a little pencilwork shows it to be true of the real numbers at least. |
23:22 | <&McMartin> | It will not work for arbitrary rings |
23:30 | <&[R]> | Yeah, I wasn't thinking on how to mathematically prove it |
