| 00:00 | <@mac> | <McMartin> That's always the joke, but I can't deny the possibility that this time it isn't |
| 00:00 | <@mac> | It isn't, but it might be alpha particles from trace radioactives in the chip casings. |

| 00:46 | <&McMartin> | OK, now that I've altered the logic and compilation options to match up the Pascal and C compilers are producing basically identical results |
| 00:48 | <&McMartin> | But even when they're both using the same assembly-based graphics core, changes in options alter run speed between 14 and 90 seconds. |
| 00:48 | <~Vornicus> | What options didn't match up |
| 00:48 | <&McMartin> | Pascal's "real" type is some weird 48-bit custom wacky thing |
| 00:48 | <~Vornicus> | Wacky |
| 00:48 | <&McMartin> | So, swap that to doubles and then turn on "generate code that uses the floating point unit" |
| 00:49 | <&McMartin> | This still doesn't explain why only DOSBox is posting the slowdown |
| 00:49 | <~Vornicus> | Yes. |
| 00:49 | <&McMartin> | But now that I've added proper timing code I guess I can test that on Win98 too and see what that's all about |
| 00:49 | <~Vornicus> | You'd expect it to pull the same thing as the BASIC |
| 00:50 | <&McMartin> | This also means that now that I've done proper apples-to-apples comparisons, the core graphics libraries aren't *that* bad |
| 00:50 | <&McMartin> | I needed to make a custom rendering primitive to actually beat them head to head |

| 06:14 | <&[R]> | Ha, someone found a weather API that defaults to kelvins. |
| 06:16 | < gizmore> | Finally unemployed... and now i can put comma as the last character in objects |
| 06:16 | < gizmore> | screw IE5 |
| 06:16 | < gizmore> | maybe i will ommit a few semicolon today *mwahahaha |
| 06:16 | <&[R]> | Webkit's JS chokes on that. |
| 06:16 | <&[R]> | The comma thing. |
| 06:17 | < gizmore> | screw webkit? nah |
| 06:17 | <&[R]> | Which means Safari and Uzbl. |
| 06:17 | < gizmore> | and mobiles |
| 06:17 | < gizmore> | and chrome |
| 06:17 | <&[R]> | Possibly others, like Konkerer. |
| 06:17 | < gizmore> | :) |
| 06:17 | <&[R]> | Not Chrome, Chrome uses V8. |
| 06:17 | < gizmore> | ah okay |
| 06:19 | <&[R]> | AFAIK there's only four major JS engines you need to worry about: Spidermonkey (Firefox), V8 (Chrome), webkit's (Tons of shit), whatever Edge uses (Edge, since IIRC they dropped JScript for something new they just wrote) |
| 06:19 | <&[R]> | I am not sure what Vivaldi and Opera run ATM. |
| 06:20 | <&[R]> | Spidermonkey does provide a CLI accessible REPL, V8 has a CLI REPL in the form of node.js |
| 06:21 | | * [R] does too much JS for his own good |
| 06:23 | | * [R] can't give the same information for layout engines. Firefox uses its own, Webkit is what Chrome and a bunch of other stuff use. |
| 06:24 | <&[R]> | Beyond that, no clue. |
| 06:24 | < gizmore> | Opera migrated to webkit |
| 06:24 | < gizmore> | so i guess v8 too |
| 06:25 | <&[R]> | V8 isn't part of webkit |
| 06:25 | <&[R]> | Webkit provides its own JS engine. |
| 06:29 | <&[R]> | Ah |
| 06:29 | <&[R]> | Opera does use V8, also Blink, which is Chromes fork of Webkit's layout engine. |

| 19:19 | <@simon_> | okay, I'm tracking a bug in our PDF parser. for some reason, U+0080 (belonging to a Unicode character class called "Cc" / Control characters) is supposed to be rendered as a ⬠(euro) sign. |
| 19:20 | <@simon_> | I'm unsure why exactly. I imagine that maybe it's a dynamically bound character code. |
| 19:20 | <@simon_> | maybe it's a sequence thing. |
| 19:20 | <@simon_> | (i.e. the subsequent byte indicating something else) |

| 19:20 | <~Vornicus> | https://en.wikipedia.org/wiki/Windows-1252 |
| 19:25 | <@simon_> | ah |
| 19:25 | <@simon_> | 0x80 is actually ⬠on windows-1252. I just realized four minutes late :) |
| 19:29 | <&McMartin> | I would normally expect Unicode to track Latin-1, not Windows-1252, but I see that Latin-1 doesn't define 80-9F as printable, so... |
| 19:31 | <~Vornicus> | Indeed, and Unicode follows latin-1 as well |
| 19:32 | <@simon_> | so somewhere in this PDF file there probably is some instruction to use Windows-1252 when those 0x80s show up. |
| 19:34 | <@simon_> | WinAnsiEncoding, it's called. |

| 20:03 | <@simon_> | hm, apparently not, exactly. WinAnsiEncoding has ⬠as 200 (0xC8), PDFDocEncoding has ⬠as U+20AC, and the Symbol set as 240 (0xF0). |
| 20:04 | | * simon_ is just thinking aloud. |
| 20:06 | <@simon_> | "Table 5.12 Differences between MacRomanEncoding and Mac OS Roman encoding", page 431 in the PDF Reference is a list of 15 codepoints where PDF's MacOS encoding differs from MacOS'es own encoding. what a depressing table. |
| 20:06 | <@simon_> | basically: "We think the MacOS encoding people are stupid for making backwards-incompatible updates to their tables, so we refuse to acknowledge these changes." |
