| 02:33 | <@celticminstrel> | ...okay. Why is everything I draw offscreen being flipped vertically. |
| 02:43 | | Turaiel is now known as Turaiel[Offline] |
| 02:43 | <@celticminstrel> | I also have no idea whether it's being flipped when first drawn or when copied onto the screen. |
| 02:44 | | Turaiel[Offline] is now known as Turaiel |
| 02:46 | <@celticminstrel> | Or when loaded, for that matter, though I doubt that would be it. |
| 02:49 | <&McMartin> | OpenGL uses mathematical coordinates, which means (0,0) is in the lower left. |
| 02:49 | <@celticminstrel> | If that was the situation, wouldn't everything be flipped? |
| 02:49 | <&McMartin> | Direct3D uses framebuffer address style coordinates, in which (0,0) is in the upper left, and more positive Y is down. |
| 02:50 | <&McMartin> | mmm |
| 02:50 | <&McMartin> | Yeah, good point |
| 02:50 | <&McMartin> | A sign error in your shaders? Crazy-ass side effects of a perspective transform? |
| 02:51 | <@celticminstrel> | I'm not actually sure what magic the display() function does, maybe it's more than simply swapping buffers... |
| 02:52 | | HotShot^Work [HotShot^Wor@Nightstar-kvnesi.sfldmi.sbcglobal.net] has joined #code |
| 02:53 | <@celticminstrel> | Also XCode, seriously, stop taking me to the wrong version of the function. |
| 02:54 | <@celticminstrel> | I know there's three functions with identical signatures, but if you can't do guess which one is right then at least put up a menu to let me choose. |

| 02:55 | <@celticminstrel> | This rendering logic is hopelessly complicated. |
| 02:57 | <@celticminstrel> | It also looks like it's all in the wrong order, though whether that's really the case, I'm not sure. |
| 03:02 | <@celticminstrel> | I guess display() also applies appropriate transformations. |
| 03:02 | <@celticminstrel> | Because calling it fixed the issue. |
| 03:04 | <@celticminstrel> | ...I'm pretty sure several of these rendering functions are being redundantly called twice during rendering. |
| 03:05 | <&McMartin> | Doing offscreen rendering I think does run you through the pipeline twice |
| 03:06 | <@celticminstrel> | That would make sense, but I mean if you make a call graph of the functions I think you'd find some are called twice. |
| 03:07 | <&McMartin> | Ah |
| 03:08 | <@celticminstrel> | Though, possibly with different arguments; some take an argument that determines whether they copy to the screen when done. |
| 03:08 | <@celticminstrel> | I want to simplify this, but I also just want it to work. |
| 03:09 | <@celticminstrel> | I still have to fix all the text being drawn too low. |

| 15:13 | <@celticminstrel> | Is 443 the normal ssh port? |
| 15:13 | <@Azash> | It's the normal HTTPS port |
| 15:13 | <@Azash> | The normal SSH port is 22 |
| 15:14 | <@celticminstrel> | Hm. |
| 15:14 | <@celticminstrel> | Does the Heartbleed thing affect ssh as well as https? |
| 15:16 | <@TheWatcher> | No |
| 15:16 | <@TheWatcher> | But anything that supports TLS is. |
| 15:17 | <@celticminstrel> | Ah, okay. |
| 15:17 | <@Azash> | Nah, heartbleed is a problem with openSSL, not openSSH |
| 15:17 | <@TheWatcher> | So https, ldap with TLS enabled, IMAP with TLS, etc |
| 15:17 | <@celticminstrel> | I thought they used the same underlying protocol. |
| 15:18 | <@Azash> | Heartbleed is an issue with openSSL specifically |
| 15:18 | <@Azash> | Not the protocols nor any other (known) implementation of them |
| 15:18 | <@celticminstrel> | So they do use the same protocol? |
| 15:19 | <@celticminstrel> | Incidentally, I changed my Google password because stackoverflow was affected. |
| 15:24 | <@Azash> | OpenSSH uses openSSL services, but IIRC Heartbleed was related to how it provides TLS, as TheWatcher said |
| 15:24 | <@TheWatcher> | Yep |
| 15:25 | <@celticminstrel> | Blargh, the checker doesn't support STARTLS. |
| 15:25 | <@TheWatcher> | http://xkcd.com/1354/ - a very short explanation of what heartbleed is. |
| 15:25 | <@celticminstrel> | I think I saw that. |
| 15:26 | <@celticminstrel> | Why is the Flash plugin crashing whenever I visit github. |
| 15:26 | <@Azash> | I particularly enjoyed how one of the few worthwhile XKCDs still manages to slip in some invalid IPs |
| 15:26 | <@celticminstrel> | Hm? |
| 15:28 | <@TheWatcher> | (essentially, you can request up to a 64K block of memory as part of the heartbeat check in TLS. Servers with heartbeat disabled are unaffected, even if they're running a vulnerable version of openssl. It's litterally just the heartbeat part of the TLS implementation of openssl that is the problem. This time.) |
| 15:28 | <@celticminstrel> | Connection refused on port 443 probably means it doesn't handle https, right? |
| 15:29 | <@celticminstrel> | Ah, that's why it's called heartbleed. |
| 15:29 | <@celticminstrel> | Wht's heartbeat? |
| 15:29 | <@TheWatcher> | Keeps the connection alive |
| 15:29 | <@Azash> | Or it's listening on a different port or something |
| 15:29 | <@Azash> | But that's unlikely |
| 15:29 | <@TheWatcher> | (well, checks that the connection is still there) |
| 15:37 | <@celticminstrel> | ... |
| 15:38 | <@celticminstrel> | Flash is crashing everywhere. |
| 15:38 | <@Azash> | http://ftp.openbsd.org/pub/OpenBSD/patches/5.4/common/008_openssl.patch |
| 15:38 | <@Azash> | Oh boy oh boy |
| 15:39 | <@celticminstrel> | Why is Flash not working. |
| 15:39 | <@TheWatcher> | Azash: *facepalm* |
| 15:40 | <@Tamber> | celticminstrel: <snark> Because Flash </snark> |
| 15:40 | <@celticminstrel> | Yeah yeah. |
| 15:40 | <@TheWatcher> | Sooo, about those alternatives to OpenSSL.... |
| 15:41 | <@TheWatcher> | Oh, wate >.< |
| 15:41 | <@Azash> | Maybe systemd will include it |
| 15:41 | <@TheWatcher> | Ugh, systemd |
| 15:44 | <@celticminstrel> | The "Send Crash Report" button when Flash crashes sends the report to Firefox, not Adobe, right? |
| 15:45 | <@celticminstrel> | Ah, it must do, the ? button links to Firefox stuff. |
| 15:49 | <@celticminstrel> | I can't change my Skype password because Flash is crashing. o.O |
| 15:50 | <@celticminstrel> | Oh wait, no, it was a cookies issue. |
| 15:50 | <@celticminstrel> | I was accepting cookies for login.skype.com instead of skype.com. |
| 15:52 | <@celticminstrel> | Everyone needs to complain to Microsoft. |
| 15:52 | <@celticminstrel> | They're limiting passwords to 20 characters. |
| 15:52 | <@celticminstrel> | And not accepting spaces. |
| 15:58 | <@celticminstrel> | Why isn't Firefox asking to save my Skype password. |
| 16:03 | <@celticminstrel> | Oh yeah, I forgot Apple sets stupid security questions. And I forgot my illogical answers. |
| 16:07 | <@celticminstrel> | I don't really mind sites requiring mixed-case or symbols, but Apple requires at least one digit and disallows multiple identical consecutive characters. The first is slightly annoying, the second is just stupid. |
| 16:07 | | * TheWatcher readsup |
| 16:08 | <@TheWatcher> | Any time a service limits password length, I default to using a crappy throw-away and not using it for anything more thna I need to |
| 16:08 | <@celticminstrel> | Heh. |
| 16:08 | <@TheWatcher> | because there's a damned good chance they're storing it plaintext |
| 16:08 | <@celticminstrel> | That's an interesting point. |
| 16:09 | <@celticminstrel> | I managed to think of something though. And it's not something I use anywhere else. |
| 16:09 | <@celticminstrel> | I still think everyone should complain to Microsoft though. Maybe if 5000 people complained they'd actually do something. >_> |
| 16:11 | <@celticminstrel> | I could actually answer some of these possible security questions, but it's probably better to use illogical answers. |
| 16:17 | <@celticminstrel> | ...... |
| 16:17 | <@celticminstrel> | Apple accepts spaces but strips them out. o.O |
| 16:17 | <@celticminstrel> | Wait, let me double-check that this wasn't Firefox getting confused. |
| 16:17 | <@celticminstrel> | It wasn't. |
| 16:18 | <@TheWatcher> | wat |
| 16:18 | < Syk> | wat |

| 18:16 | <@celticminstrel> | What sort of container is best for a "history" buffer which saves recent messages? Basically, it should have a maximum length, and if something is added when it's full, the oldest message is dropped. |
| 18:36 | <@Tarinaky> | celticminstrel: A cyclic linked list? |
| 18:37 | <&jeroud> | A deque? |
| 18:38 | <@celticminstrel> | boost::circular_buffer? |
| 18:38 | <&jeroud> | A circular buffer is usually a different thing. |
| 18:38 | <@Tarinaky> | Oh, this was specifically a C++ question. |
| 18:38 | <@celticminstrel> | Hm. |
| 18:38 | <&jeroud> | Byte-oriented. |
| 18:38 | <@celticminstrel> | Yeah Tarinaky, sorry for not mentioning. |
| 18:39 | <@celticminstrel> | jeroud: It's templated. |
| 18:40 | <@Tarinaky> | I don't think there's specifically a container for it in STL |
| 18:40 | <@celticminstrel> | Yeah, there's nothing like that in STL. |
| 18:40 | <@Tarinaky> | You could probably just allocate an array and a pointer offset for the head. |
| 18:41 | <@celticminstrel> | No thanks. |
| 18:41 | <@celticminstrel> | Actually, that's probably how it works right now, more or less. |
| 18:42 | <@celticminstrel> | Yeah, looks like it, except instead of a pointer it stores an index. |
| 18:42 | <@celticminstrel> | Pretty much the same thing. |
| 18:42 | <@Tarinaky> | I said a pointer offset, not a pointer :p |
| 18:42 | <@celticminstrel> | Fair enough. |
| 18:42 | <@celticminstrel> | I guess it's exactly what's being done then. :P |
| 18:42 | <&jeroud> | celticminstrel: You could use a deque and check size on insert. |
| 18:43 | <@Tarinaky> | Modifying an STL container to do /exactly/ what you want isn't worth the candle. |
| 18:43 | <@celticminstrel> | But I want to consider expanding the size of the buffer, maybe even making the size configurable, so... |
| 18:43 | <@Tarinaky> | Then use a vector or a deque instead of an array. |
| 18:43 | <@celticminstrel> | I'm going to double-check boost::circular_buffer first. It might be what I want. |
| 18:44 | <@Tarinaky> | But otherwise just handle the end of the container as a special case. |
| 18:44 | <@celticminstrel> | Now that you mention it, it would be pretty easy to do with a deque. |
| 18:45 | <@Tarinaky> | if next() is the end() return begin() or whatever the names of the methods are. |
| 18:45 | | * Tarinaky really should remind herself >.< |
| 18:46 | <@celticminstrel> | Basically, if I want to add something and it's full, remove the first element. |
| 18:46 | <@Tarinaky> | Not even that, just modify the data of the first element. |
| 18:46 | <&jeroud> | I was actually thinking about undo rather than history. |
| 18:46 | <@Tarinaky> | Don't remove it from the container. |
| 18:46 | <@Tarinaky> | Just overwrite it. |
| 18:46 | <@celticminstrel> | That would be more complicated. |
| 18:47 | <&jeroud> | A deque might not work if you want to access arbitrary entries. |
| 18:48 | <@celticminstrel> | Oh, right, it's not random access, is it... |
| 18:48 | <@Tarinaky> | Which is why I thought a vector would be easier. |
| 18:49 | <@celticminstrel> | A vector doesn't have a remove front method, so I'd have no choice but to do the circular thing manuall. |
| 18:49 | <@celticminstrel> | A vector doesn't have a remove front method, so I'd have no choice but to do the circular thing manually. |
| 18:49 | <@celticminstrel> | Uh, I was going to just ^correct that. Oh well. |
| 18:49 | <@celticminstrel> | Then again, it's already doing the circular thing manually. |
| 18:49 | <@Tarinaky> | I'm still not sure why you want to remove the data from the container instead of just overwriting it. |
| 18:49 | <@celticminstrel> | I was just saying it would be easier to do it that way. It's probably better not to. |
| 18:50 | <@celticminstrel> | There's no fixed-size container with size settable at runtime, is there? |
| 18:50 | <@celticminstrel> | Like std::array with the size a constructor parameter instead of a template parameter. |
| 18:50 | <@Tarinaky> | std::vector's constructor has a parameter for it. |
| 18:51 | <@Tarinaky> | And there's a set size method. |
| 18:51 | <@celticminstrel> | Making the size in std::array a template parameter strikes me as a poor choice, honestly. |
| 18:52 | <@Tarinaky> | It's not a template parameter. |
| 18:52 | <@celticminstrel> | Yeah, std::vector would certainly work, but it's technically not fixed size. :P |
| 18:52 | <@celticminstrel> | Uh, yes, it is a template parameter. |
| 18:52 | <@celticminstrel> | std::array<int, 6> --> an array of 6 ints |
| 18:52 | <@Tarinaky> | Oh. I thought we were talking about vector. |
| 18:52 | | * Tarinaky didn't know there was a std::array o.o |
| 18:53 | <@celticminstrel> | I said quite clearly that I was talking about std::array. :P |
| 18:53 | <@Tarinaky> | Yes, but I thought you were being confused. |
| 18:53 | <@celticminstrel> | Ah. |
| 18:54 | <@Tarinaky> | Anyway, I thought you wanted to change/specify your size at runtime... which means a vector. |
| 18:55 | <@celticminstrel> | Okay, boost::circular_buffer does do exactly what I want, it seems. |
| 18:56 | <@celticminstrel> | "If the latest data is the most important, write over the oldest data" |
| 18:56 | <@celticminstrel> | I was actually using an std::list for undo/redo, by the way. (Because someone mentioned undo.) |

| 19:28 | <@celticminstrel> | I wonder if Firefox has any way to direct links from other applications to a certain tab group... |
| 19:30 | <~Vornicus> | Probably not; I don't think it gets that information. |
| 19:40 | <@celticminstrel> | Really? You don't think it can tell the difference between "link typed into the address bar" and "link requested from another application"? |
| 19:40 | <@celticminstrel> | That's not really specific enough for what I had in mind, though. |
| 19:41 | <~Vornicus> | What I mean is |
| 19:41 | <~Vornicus> | -- and what I thought you meant, at that -- |
| 19:41 | <~Vornicus> | was that I don't think it knows from which application the request came. |
| 19:42 | <@celticminstrel> | Yeah, that was what I wanted. |
| 19:44 | <@celticminstrel> | ...wait. I lost a Firefox toolbar. How on earth did that happen? |
| 19:44 | <@celticminstrel> | My custom toolbar with additional buttons has disappeared. |
| 19:45 | <~Vornicus> | I don't even know what to google to figure out where to look for that information |

| 22:27 | <@celticminstrel> | With stencil function on "always", I'm drawing a square of pixels, some of which are transparent. |
| 22:27 | <@celticminstrel> | Maybe it sets the stencil to 1 even for the transparent pixels? |
| 22:29 | <@celticminstrel> | Hm, no, if I fail to restrain the rect, it doesn't clip to the mask rect. |
| 22:34 | <@celticminstrel> | Oh wait, I may be drawing the wrong mask. |
| 22:36 | <@celticminstrel> | Nope. |

| 23:45 | <@celticminstrel> | I don't understand why this is drawing solid black instead of the desired texture subrectangle. As far as I can tell I'm doing the exact same thing just a bit later (though with a different rect), and it works. |
| 23:54 | <@celticminstrel> | Oh, wait. I had the coordinates swapped for just that one rect. |
