I'm running Google Chrome Canary. Is there a way to, via the command line, force Google Chrome Canary to reload?

https://www.amazon.com/dp/B00JLRBC7S <-- apaprently this doesn't work with apple either

besides matrox, does anything work with apple for splitting one displayport into 2 (non-mirrored) monitors

@qqq sorry i can't help you there, instead i'd like to ask a counterquestion: during your research, have you found evidence of somebody driving a 4k/60Hz display successfully with a 2012 MBPr?

it would have to be through thunderbolt i presume.

@shem: do you have this 2012 MBPr on hand?

2.5km away

@shem: if you click apple icon -> support -> specifications, it'll pop up a webpage which will show precisely the model you have and what it supports; mine for example, is https://support.apple.com/kb/SP704 which clearly says only 2 external monitors basically I've concluded that youtube/blogs about "year-X mbps supporting XYZ" are worthless and I should only trust the apple specs 🙂

right. I'll check this. i'm beginning to think 4k/60 is a pipe dream with this machine.

thanks

@shem: my 2014 model only supports

Support for 1080p resolution at up to 60Hz
Support for 3840-by-2160 resolution at 30Hz
Support for 4096-by-2160 resolution at 24Hz

that's under hdmi though. it says nothing about resolutions under thunderbolt video

the discrete video card in my machine is GT650

ah; that's true; I know nothing about thunderbolt displays

That moment when you run this in Python, and it works: assert 0 in [False, None]

(facepalm) why can't all languages have sane equality semantics?

user> (= 0M 0.0M)
true
user> (.equals 0M 0.0M)
false

But that's just Clojure vs Java equality

@tbaldridge I spent a lot of time debugging some Python code written by a clojurian, until I realised that the code was falsey when it wouldn't be in Clojure.

It is, yes, and I don’t… entirely disagree with clojure’s choice tbqh, but it was surprising when I discovered datomic uses Java’s definition of equality 😕

Oh really?

@donaldball how did that manifest?

Simply a failure to process import jobs idempotently, when the entity in question already was stored with e.g. value 2000.00M, and the potential entity to transact had value 2000M. The outerlying problem was entirely my failure to read the fine print on the bigdecimal divide method, to be sure. My underlying takeaway is that equality is damn hard, even for principled projects developed by the same authors. 🙂

anyone here using an AppleTV as an external monitor? if so, what is the lag like? (and which generation, 1st, 2nd, 3rd, or 4th are you using)
