| 17:26 | | * Tamber ugh |
| 17:27 | <@Tamber> | Trying to figure out why I'm having issues with my phone and wifi; and it's very very difficult to construct a useful search for "my android phone sometimes just won't connect to the wifi, either apparently giving up and just marking it as 'saved', sometimes deciding it's 'authentication problem', occasionally getting as far as 'connected but no Internet', and sometimes [...] |
| 17:27 | <@Tamber> | [...] behaving just fine. All without any change to the network settings." |
| 17:28 | <@Tamber> | Because 99.5% of the results are "Just delete the network from your saved networks, and re-enter it."/"You've put the password in wrong." |
| 17:28 | <@Tamber> | And it's frustrating me because I cannot seem to find any way to figure out what the shit it's doing. |
| 17:29 | <&[R]> | I had issues like that when Telus' little problem-maker decided it needed to ping-scan the entire internal network twice an hour |
| 17:30 | <&[R]> | IE: the wifi was flooded |
| 17:30 | <@Tamber> | Yick. |
| 17:32 | <&[R]> | Also it didn't have that behavior before, nor did anyone in the house push an update to it :/ |
| 17:32 | <@Tamber> | (Now I have 'authentication problem' but the router's status page is showing my device as connected. Uhh.) |
| 17:38 | <@Tamber> | I mean, I get it, my network setup isn't 'normal' for a consumer home network; but this is just stupid and frustrating. Roll for network connectivity, I guess? |
| 17:40 | <&[R]> | In what way? |
| 17:41 | <&[R]> | ATM: I have a 10.0.0.0/8 network, DHCP is on one host, DNS is on another and the wifi AP is simply a bridge, the external gateway is a fourth box. |
| 17:41 | <&[R]> | Android wifi works fine with that |
| 17:42 | <@Tamber> | 'Not normal' in that I'm not using the ISP provided router for everything, as is the norm for non-technical households. :p |
| 17:43 | <@Tamber> | I've got a 192.168.0.0/24, DHCP/DNS provided by a box I control, and the ISP router is the modem, gateway, and wifi AP. |
| 17:43 | <@Tamber> | (Because if I let the ISP's little box do the DHCP, I cannot choose what DNS it uses. And theirs is shit.) |
| 17:43 | <@Tamber> | And this setup has worked before. |
| 17:44 | <@Tamber> | Now it doesn't, and I have no way of finding out why. |
| 17:44 | <&[R]> | Ah yeah, that external gatway is it's own box, it connect to Shaw's modem. The Telus router (which is the problem-maker) is no longer on the main network. It merely feeds the TVs now. |
| 17:45 | <&[R]> | Hmm, is the wifi in bridge mode? |
| 17:45 | <&[R]> | Are you getting the DHCP responses? |
| 17:45 | <@Tamber> | no option to say what mode the wifi is in. And I have no way of knowing whether the phone is getting the DHCP responses. |
| 17:46 | <@Tamber> | Other than when it occasionally *does* decide to all work, and it connects. |
| 17:47 | <&[R]> | No other wifi devices to test with? |
| 17:47 | <@Tamber> | Oh! Hang on, I have the dhcpd logs. |
| 17:47 | <@Tamber> | ...and it appears to have worked this time. |
| 17:48 | <@Tamber> | ...and then it randomly went "no signal" and dropped. |
| 17:50 | <@Tamber> | Doesn't look like it's getting to the stage of making DHCP requests. |
| 17:50 | <@Tamber> | oh, it did this time. |
| 17:51 | <@Tamber> | Now it's got an IP address, but it's claiming there's no internet access. |
| 17:52 | <@Tamber> | (now fully connected... *shrug*) |
| 17:55 | <@Tamber> | And laptop has no problems connecting to the wifi and working. So it must be something with the phone. |
| 17:58 | <&[R]> | What phone? |
| 17:59 | <@Tamber> | Cubot Cheetah2, running Android 7.0 |
| 18:00 | <&[R]> | I haven't ever heard of that |
| 18:01 | <&[R]> | FWIW I'm using two Samsung devices (5.0 and 6.0) and one LG device (7.0) on my network without issue. |
| 18:02 | <@Tamber> | *nod* My issues have only started fairly recently, but until then I didn't have any particular problems. |
| 18:03 | <&[R]> | Might be an ISP pushed update to your modem? |
| 18:03 | <@Tamber> | It's always a possibility. |
| 18:03 | <&[R]> | Check for any flooding too |

| 23:34 | <~Vornotron> | ok. array roll in 1-indexed language. |
| 23:35 | <&[R]> | ? |
| 23:38 | <~Vornotron> | making delaunay triangulation in lua. current mini problem is - it's possible to land a new point directly on an edge; in this case I have to split two triangles up into pairs; because of the way this works out it's *way* less of a hassle to roll the triangle's vertices so that the edge we're splitting is the first one, than to try to pick the right indices based on which edge we're splitting |
| 23:39 | <~Vornotron> | But: array rolling is way less pleasant when you are working with 1-indexing. |
| 23:39 | <~Vornotron> | I guess I can just use insert and remove |
| 23:41 | <&ToxicFrog> | "array rolling"? |
| 23:42 | <&McMartin> | like bit rotation but array elements, I think |
| 23:43 | <&ToxicFrog> | insert and remove are O(length of array following the elements you're manipulating) so be wary. |
| 23:43 | <~Vornotron> | triangles, so... 3 |
| 23:44 | <&ToxicFrog> | Oh! I was thinking array of triangles, not array storing one triangle |
| 23:44 | <&ToxicFrog> | If you don't need a general array roll implementation, this is really simple: |
| 23:44 | <&ToxicFrog> | tri[1],tri[2],tri[3] = tri[2],tri[3],tri[1] |
