Bloody posted:another day, another round of being driven to madness by mutable data Join the loving club. im trying to convince the people in charge of our data that maybe they should not overwrite existing data, but actually keep a record of changes so we can reproduce the state of the data at a later point in time.

lmao we've been generating invalid "ghost" <a> references on this grid for years because the grid plugin was trying to load from a data structure that didn't exist because the base table was pre rendered, but we never noticed because the function over the data did this:code:and ofc javascript is terrible so if data[FartID] doesn't exist it returns undefined which then silently casts to string, builds an invalid url to \undefined, but because CellValue is already a valid url because we pre rendered it, it creates a weird nested anchor that renders as an invisible <a> with no value and then a valid one next to it so it all looked fine unless you inspect the elements only noticed because there was a non-url column that the same render function was applied to and it threw a "value is undefined" error because it didn't need to concatenate anything so didn't do the implicit cast

MononcQc posted:It sure required less mutability. I did end up going with the easy thing of generating all points in both paths and then just combining them as a set intersection because I couldn't remember how to properly do line collision effectively and I didn't want to look dumb on video. I should probably figure it out that way though. mystes fucked around with this message at 20:48 on Dec 3, 2019 |

Wheany posted:....yeah, i guess i'm not going to even bother starting the advent of code I just did a brute force thing: if the line is from {0,5} to {3,5}, I just add {0,5},{1,5},{2,5},{3,5} to a set, do that for all lines, and check for the sets that share the same points. If you use the proper data structure, it takes a reasonable amount of time and does not feel like brute-force at all.

mystes posted:You mean you literally just generated all the points in each segment rather than looking at pairs of segments to see if they intersected? Checking for intersections isn't that bad because the segments are all either vertical or horizontal. Yeah exactly. Then I put each wire layout in a set, find the intersecting points, and then do the calculations they ask for. If you keep a list of all the points in order then part 2 is just about counting all the non-matching points until you get the matching one. Took me about 200ms in Erlang (which isn't a super fast language) including disk access for the problem definition. Was fast enough for me to call it a day.

the database people have to trust the filesystem people though, since they rely on the filesystem for things like "cache this page" or "sync to disk". well postgres does anyway, oracle not so much

There is an MBA CFO who somehow has the responsibility for IT, but no understanding of it... I'll let you figure out if IT is a value-generating entity in his eyes, or a cost to be minimized aggressively to the point where i have to argue when I want a VM with more than 2 gigs of RAM and 40 gigs of space
