19:40:28 <orby_work> It's actually quite interesting to think about the various ways one can usefully cast between a logical, integer, list, and set. A logical most obviously casts to a bit list, but when casting to a set you can think of a logical as an inclusion mask for the set (i.e. if bit i is set, then integer i is in S).
19:41:02 <orby_work> While an integer might just cast to a singleton set.

20:48:43 <ais523> could someone tell me if there's currently an Internet backbone dispute going on? many websites work fine for me, but many connections on port 80 get a "connected", followed by no response from the other end until the connection times out
20:48:55 <ais523> and all the websites I normally check to see if there's an ongoing backbone dispute are in the latter group
20:49:23 <ais523> so either something's gone badly wrong at my ISP, or else there's a rift in the Internet again, and I'm trying to determine which

21:01:05 <b_jonas> hi
21:01:52 <ais523> currently struggling with a malfunctioning Internet connection, a sizeable minority of websites are failing (if I connect to them on port 80, the connection is accepted but the website never sends anything), I'm wondering if it's a backbone dispute or whether it's something at my ISP
21:02:32 <orin> the internet is working fine for me
21:02:52 <ais523> oh, hmm, it just fixed itself
21:03:06 <orin> maybe a DNS crapout
21:03:08 <orin> ?
21:03:30 <int-e> it could be some "transparent" HTTP proxy
21:04:00 <ais523> orin: definitely not DNS, that's the first thing I checked
21:04:13 <ais523> but it'll be hard to diagnose now that it's stopped

21:08:54 <ais523> and the failing sites just sent no response, even though the connection wasn't refused

21:17:01 <orin> b_jonas: not yet
21:18:28 <orin> b_jonas: I did manage to do it by simply dumping the characters and running sort over them

22:42:33 <FreeFull> ais523: Maybe packets were just being dropped hard en-route?
22:42:45 <FreeFull> And TCP had to keep retrying?
22:42:53 <ais523> FreeFull: yes, it's consistent with the packets being hard-dropped
22:43:04 <ais523> although, would TCP report "connection established" before a single inbound packet was received?
22:43:16 <FreeFull> ais523: Next time it happens, try pinging some IP and seeing how long the responses take, and how many get dropped
22:43:41 <FreeFull> A connection definitely requires a bit of back and forth to be established
22:43:50 <FreeFull> But it's possible the first few packets were always getting through for some reason

23:07:01 <orin> Tim Apple, and his friends Satya Microsoft and Sundar Google

23:08:01 <shachaf> have you considered putting all your c++ files into one compilation unit to make the build faster hth
23:08:12 <shachaf> itim translation unit
23:10:10 <orin> shachaf: we can't even fit the list of c++ files into a single command line
23:10:40 <orin> I don't thing even a tenth of it would fit in memory at once
23:11:21 <shachaf> imo make your builds fast
23:11:25 <shachaf> then you'll be less miserable
23:13:27 <fizzie> Have all your developers sync to last green of a CI build, then you can cache compilation artifacts.
23:14:10 <shachaf> continuous integration is the worst name
23:14:24 <shachaf> integration already sounds like the math
23:14:37 <shachaf> and the word "continuous" seems to settle the matter unambiguously
23:14:44 <j4cbo> d e v o p s
23:28:32 <orin> fizzie: lol compilation artefacts
23:28:50 <orin> fizzie: this thing compiles the same files multiple times for some reason
23:29:28 <shachaf> orin's build system is just a disaster, is the background behind all this
23:29:45 <shachaf> and orin inc. would rather have builds take 12 hours than fix it
23:30:51 <fizzie> On the other hand, "orin inc." sounds pretty snappy. Financial, maybe.
