| 00:45 | <&ToxicFrog> | Huh |
| 00:46 | <&ToxicFrog> | I think this is the first stack trace I've gotten out of lua that's completely, legitimately useless |
| 00:46 | <&McMartin> | ...gratz? |
| 00:46 | <&ToxicFrog> | luajit: bad argument #2 to '?' (function expected, got nil) |
| 00:46 | <&ToxicFrog> | stack traceback: |
| 00:46 | <&ToxicFrog> | [builtin#21]: at 0x00447210 |
| 00:46 | <&ToxicFrog> | [C]: at 0x00404980 |
| 00:46 | <&Derakon> | Haha. |
| 00:46 | <&Derakon> | That is not very helpful, no. |
| 00:50 | <&McMartin> | Start looking for one-argument built-in functions that need two arguments? |
| 00:51 | < catalyst> | Pray to the moon? |
| 00:53 | <&ToxicFrog> | Found it! |
| 00:53 | <&ToxicFrog> | This is what happens when you forget to pass an error handler to xpcall() but also call it in tail position so the stack frame gets thrown away |
| 00:54 | <&ToxicFrog> | It can't figure out what name you called the function as |
| 00:54 | <&McMartin> | That was less than ten minutes! Not bad at all |

| 02:25 | <&ToxicFrog> | Argh. |
| 02:25 | | * ToxicFrog tracks down an issue with log messages from program startup not being logged |
| 02:26 | <&ToxicFrog> | So, it used to be that stuff logged before argument parsing just got dropped |
| 02:27 | <&ToxicFrog> | I did some reworking; it loads the minimum possible, then does a permissive parse to pick up (among other things) --log-level and --log-to |
| 02:27 | <&ToxicFrog> | Then it loads everything else so that all the flags are registered and then does a strict parse. |
| 02:28 | <&ToxicFrog> | But this causes --log-to to get parsed twice, which means it re-open()s the log file with mode 'w'. |
| 02:30 | <&McMartin> | argh, everything is terrible |
| 02:31 | | * McMartin hives off his entire branch he's been working on all week, because it's achieved nothing but demonstrate a huge set of overly-strict preconditions within the rest of the codebase. |
| 02:31 | <&McMartin> | Time to go fix *those*. |

| 18:23 | | * jerith tries to figure out a factorio program. |
| 18:24 | <&jerith> | As inputs, I have a chest with an iron plate count and a chest with a copper plate count. |
| 18:26 | <~Vornicus> | ooh, factorio |
| 18:26 | <~Vornicus> | these plates are of course actually in the chest yes |
| 18:26 | <&jerith> | As outputs, I want a line that says "copper ore" if iron+X>copper, otherwise "iron ore", and a second line that says "copper ore" if iron>copper+X, otherwise "iron ore". |
| 18:27 | <~Vornicus> | and X is coming out of a constant combinator? |
| 18:27 | <&jerith> | Either that or hardcoded. |
| 18:29 | <&jerith> | The idea is that if I have too much of one or the other, my furnaces only smelt the one I have less of. If I have about the same amount of each, half my furnaces smelt one and the other half smelt the other. |
| 18:29 | <~Vornicus> | Right. |
| 18:29 | <&jerith> | I'm pretty sure I can do this with two arithmetic combinators and four decision combinators. |
| 18:30 | <~Vornicus> | this 13.x or 12.x |
| 18:30 | <&jerith> | 0.13.9. |
| 18:32 | <&jerith> | (I don't think 0.12.x has enough functionality to actually do this.) |
| 18:32 | <&jerith> | I *really* want to base my decision on the logistic network data, but I haven't been able to figure out how to get that into combinators. |
| 18:33 | <&jerith> | So I'll satisfy myself with using these boxes for now. |
| 18:34 | <&jerith> | I was hoping to do it with two arithmetic and two decider combinators, but I don't think that's actually possible. |
| 18:34 | <~Vornicus> | feels like you should be able to do it with two decision combinators |
| 18:34 | <~Vornicus> | heh |
| 18:40 | <&jerith> | There doesn't seem to be a way to ask for the maximum signal or whatever. |
| 18:40 | <&jerith> | So I'd have to make that out of a pair of deciders or something. |
| 18:41 | <&jerith> | Hrm. |
| 18:43 | <&jerith> | I could use a pair of arithmetic combinators to take the average of two values. |
| 18:43 | <&jerith> | Then I can use a decider to pass along any signal with a value larger than that average. |
| 18:44 | <&jerith> | That gives me a "max" for the cost of two ariths and a decider. |
| 18:44 | | ion [Owner@Nightstar-6grqph.vs.shawcable.net] has quit [[NS] Quit: disconnected] |
| 18:48 | <&jeroud> | That, along with my threshold logic, comes to a total of six ariths and two deciders. |
| 18:49 | <&jeroud> | Which is more expensive than the other thing. |

| 18:52 | | * jeroud resists the urge to design a neural network made of deciders, because there's no way automate weight adjustment. |

| 18:59 | <&jeroud> | It would be nice to have a way to set various combinator parameters from the outside. |
| 19:00 | <&jeroud> | Then you could blueprint a circuit and have one place to say "look at these signals". |
| 19:00 | <&jeroud> | (Instead of configuring each component by hand.) |
| 19:03 | | * jeroud resists the urge to build a thing that reads some kind of signal expression and outputs an optimal combinator circuit. |
| 19:03 | <&jeroud> | It's probably not all that hard to do, actually. |

| 19:06 | | Derakon[AFK] is now known as Derakon |
| 19:06 | <&jeroud> | I've just figured out how to do the max thing with one arith and one decider, but I need an extra combinator as an isolation buffer to make it work. |
| 19:06 | <&jeroud> | I think. |
| 19:07 | <~Vornicus> | does it *have* to output copper ore or iron ore? what if they output other signals? |
| 19:08 | <&jeroud> | I'd need another component to translate back into the signal I need. |
| 19:08 | <&jeroud> | This is going to set filters on inserters. |
| 19:09 | <~Vornicus> | oh I see. I thought it was pulling in ore from two different |
| 19:09 | <&jeroud> | My inputs are plate and my outputs are ore. |
| 19:09 | <~Vornicus> | like, two belts, one with copper and one with iron on it, that you then fill onto the furnace system |
| 19:10 | <~Vornicus> | so you could just turn on the inserters. |
| 19:10 | <&jeroud> | I have one belt with both ores on it and select which to insert into the furnaces. |
| 19:11 | <&jeroud> | I could just switch the inserters, but then I need twice as many. |
| 19:13 | <&jeroud> | At the moment, I have filter inserters that decide if they're on or off by comparing iron plate to copper plate in the logistics network. |
| 19:13 | <&jeroud> | But that's either all one or all the other. |
| 19:14 | <&jeroud> | I want the three state system. |
| 19:15 | <&jeroud> | It would be nice if the decider let one choose between two outputs. |
| 19:16 | <&jeroud> | But then that wouldn't play nicely with every/any/each. |
| 21:07 | | * Tamber ponders. |
| 21:07 | <@Tamber> | Reason: "Internal error on microcontroller board" Solution: "Change or change main-board" |
| 21:30 | <&ToxicFrog> | Hmm. |
| 21:31 | <&ToxicFrog> | This is the place where (binding) would be really, really handy. |
| 21:31 | <&ToxicFrog> | Sadly, Lua doesn't have it. |
