06:42 <Jbbouille> mcguire: I have llvm-devel-3.7.0-4.fc23.x86_64 and I don't know where the `LLVMOrcJIT` is coming from. See full trace at https://gist.github.com/Jbbouille/e2443cbdcb0c88f20278b2b023825cf3

06:42 <Jbbouille> mcguire: should I re install llvm ?

06:43 <Jbbouille> mcguire: Thx for the answer by the way.

07:42 <Jbbouille> For the record I found my issue

07:42 <Jbbouille> I wasn't using the right version of LLVM (3.7.0 instead of 3.7.1).

13:02 <SeanTAllen> 3.7.0 is very broken

13:57 <Candle> What is the correct pattern for "I can't set this variable to what I need it to be at constructor time, and therefore I will have to check that it's the type I want every time I use it" (i.e. 'if (field != null) field.bar()')

14:29 <jemc> Candle: checking the field type every time is definitely one pattern, for example: `try (field as Foo).bar() else ... end`

14:30 <jemc> another pattern is using an interface as the type of the field, and providing a no-op class that meets the interface

14:30 <jemc> I'll see if I can pull an example like that from my code

14:33 <jemc> Candle: here is a file with an example

14:33 <jemc> https://github.com/jemc/pony-zmq/blob/master/zmq/zmtp/session.pony

14:34 <jemc> I create an interface called `SessionHandleReceived`, and a class called `SessionHandleReceivedNone` which implements that interface, but does nothing when it receives a message

14:35 <jemc> so I can set the field with that as the initial value, and assign a "real" handler to it later `var received: SessionHandleReceived = SessionHandleReceivedNone`

14:35 <Candle> jemc: Thanks. The type in question is a TCPConnection, so creating an interface for it doesn't fill me with enthusisam.

14:37 <jemc> well, if it helps, you only need to make an interface with the methods that you use

14:38 <Candle> That's true...

14:38 <jemc> it's up to you to decide whether it is more onerous for you to check the type everywhere or define an interface and dummy type

14:44 <ohir> jemc: is there some talk avaliable to the slides you gave recently (about the herd of ponies as of sept 13)?

14:45 <jemc> ohir: I don't think I gave such a talk - you might be thinking of someone else's talk?

14:48 <ohir> {04/26/2016 22:16 jemc/#pony} http://www.doc.ic.ac.uk/~scd/Disributed_Pony_Sept_13.pdf

14:50 <jemc> oh, I see, you mean "gave" as in "pasted the link" - I thought you were talking about a talk that I "gave" as in "presented"

14:51 <ohir> :) yep.

14:54 <ohir> jemc: slides look like they were prepared for a seminar or webinar

14:54 <jemc> I don't know of a video link for that, but I just did a youtube search and found this, which may be helpful: https://www.youtube.com/watch?v=fNdnr1MUXp8

14:55 <jemc> also found this, but may be less related: https://www.youtube.com/watch?v=KvLjy8w1G_U

14:56 <ohir> jemc: thx, first I have, second I will in an hour :)

14:56 <ohir> jemc: as for the slides, the MSc paper has more details.

22:41 <mcguire> This might be a bit of a personal question, but just out of curiosity: why does the runtime do funny things to the tty? stdin_tty in libponyrt/lang/stdfd.c
