| 03:30 | <@Reiv> | A puzzle in SQL (SQL Server, if it makes a difference): |
| 03:30 | <@Reiv> | We all know how LIKE works. |
| 03:31 | <@Reiv> | Is there a way to compare two columns against each other with a LIKE in place? |
| 03:31 | | * Reiv suspects the question is nonsensical, but isn't too sure how else to do it. |
| 03:33 | | Kindamoody[zZz] is now known as Kindamoody |
| 03:38 | <@Reiv> | Basically, I have two columns, and am trying to find out how many rows of these are mostly, but not quite, the same. |
| 03:39 | <@syksleep> | um |
| 03:39 | <@Reiv> | To which I mean I'm willing to accept up to two characters at the front of each, or one non-numeric character on the end of either, and provided the rest in between is the same, it's considered equivalent. |
| 03:40 | <&Derakon> | So if a[2:-1] == b[2:-1] then they match? |
| 03:40 | <&Derakon> | Well, but you have that non-numeric constraint. |

| 09:14 | <@Syk> | tamber i hate you and your nice weather |
| 09:14 | <@Syk> | well when i move to sydney, they have a good 10 or so rainy days a month every month |
| 09:14 | <@Syk> | i can pretend i'm living in birmingham or something |
| 09:14 | <@Tamber> | What, with only 10 rainy days a month? |
| 09:15 | <@Syk> | i said pretend |
| 09:15 | <@froztbyte> | Syk: sounds about right |
| 09:15 | <@Syk> | okay so |
| 09:15 | <@Tamber> | la |
| 09:15 | <@Syk> | i had some rain two weeks ago |
| 09:15 | <@Syk> | like, a bit |
| 09:15 | <@froztbyte> | around where I stay in .za, it can be up to 30-odd some time in the evening still |
| 09:15 | <@Syk> | for like an hour |
| 09:15 | <@TheWatcher> | Tamber: "ominous void"? your METAR reader has a sense of humour. |
| 09:15 | <@Syk> | where is za |
| 09:15 | <@Syk> | oh south africa |
| 09:15 | <@Tamber> | TheWatcher, I have a small list of random crud to use if METAR doesn't return a weather condition. :) |
| 09:16 | <@TheWatcher> | That said, that is Manchester Airport, Ominous Void is probably accurate... |
| 09:16 | <@Syk> | okay so |
| 09:16 | <@Syk> | the whole year so far |
| 09:16 | <@Tamber> | Wouldn't surprise me in the slightest. |
| 09:16 | <@Syk> | like, to-the-day |
| 09:16 | <@Syk> | 79 days of rain |
| 09:17 | <@Syk> | with the highest being 75mm in one day |
| 09:19 | <@Syk> | Tamber: the lowest ever recorded temperature is 6.7C |

| 09:22 | <@Syk> | Tamber: that was in 2008 |

| 09:22 | <@Syk> | >lowest maximum ever recorded: 16.7C |

| 15:22 | < RichyB> | gnolam: aren't those two completely different axes? |
| 15:23 | <@TheWatcher> | I wonder just how many people questioned the existence of cake in the context of testing, anyway. |
| 15:27 | <@froztbyte> | hahaha |
| 15:29 | <@Syk> | the cake is a l-*shot* |
| 15:30 | < RichyB> | gnolam: I wonder whether you'll get a single fasted AND cheapest implementation... |
| 15:30 | < RichyB> | or whether a bunch of people will come up with a non-dominated front. |
| 15:30 | < RichyB> | Some faster, some cheaper. |
| 15:31 | <~Vornicus> | what is "cheap" and what is "fast" in this context |
| 15:31 | < RichyB> | oh, good point Vornicus. |
| 15:31 | < RichyB> | 3 different axes. |
| 15:32 | <@froztbyte> | from another channel |
| 15:32 | <@froztbyte> | <cwillu_at_work> susceptibility to flour-based incentives is a key requirement in any candidate |
| 15:32 | < RichyB> | Fast is time taken to decode some sample image(s), which is easy enough to measure. |
| 15:32 | < RichyB> | Actual wall-clock time is unambiguous. |
| 15:34 | < gnolam> | He said fastest first. Then changed it to cheapest above a certain FPS threshold. |
| 15:34 | < gnolam> | In other words, he'll decide which he likes best. ;) |
| 15:34 | < RichyB> | One axis of "cheap" is, "how many transistors does it take to build this circuit?" (or logic units or whatever they're called, on an FPGA) |
| 15:34 | < RichyB> | The other axis of "cheap" is "how many joules does this circuit burn while decoding the sample image(s)?" |
| 15:36 | <@Syk> | does that cover computationally cheap |
| 15:37 | < gnolam> | Hardware units. |
| 15:37 | <@Syk> | oh SOC is circuits isnt it |
| 15:37 | <&ToxicFrog> | System On Chip. IC design. |
| 15:38 | <@TheWatcher> | gnolam: Bonus points for an implementation that makes http://l-userpic.livejournal.com/68895387/2147443 appear as a watermark in decoded images~ |
| 15:38 | <@Syk> | oh dear jpg on a chip |
| 15:38 | <&ToxicFrog> | And yeah, "cheapest implementation capable of 30fps decoding" sounds reasonable as long as you can agree on which metric is used for "cheap" |
| 15:38 | < gnolam> | TheWatcher: :) |
| 15:38 | <@Syk> | maybe i might take up something like that when I move to the city |
| 15:39 | <@Syk> | i'd love to get into circuitry, even low-tech sort of stuff with ardunios and all |
| 15:39 | <@Syk> | but there's not a radioshack for ten hours drive :( |
| 15:39 | <@Syk> | and waiting 999 weeks for Australia post to mangle your breadboards and resistors isn't fun |

| 18:49 | <@Tamber> | "badly"? |
| 18:51 | < jeroid> | Barely? |
| 18:52 | < Tarinaky> | The internet police are currently investigating someone sending spoofed emails from staff. |
| 18:52 | <@Tamber> | Occasionally, then it explodes? :D |
| 18:52 | <@Tamber> | the "internet police"? |
| 18:52 | < Tarinaky> | As in the Uni has contacted the Police. Who, naturally, haven't done much. |
| 18:52 | <@Tamber> | Of course. |
| 18:53 | < Tarinaky> | Due to not knowing one end of a USB cable from the other :) |
| 18:53 | < jeroid> | Why not ask the IT people? |
| 18:53 | < Tarinaky> | They've blocked the website used to generate the emails. |
| 18:54 | < Tarinaky> | As far as I am aware, nobody seems to have gotten into any serious trouble. |
| 18:54 | < jeroid> | (Who likely don't know any better.) |
| 18:54 | < Tarinaky> | I imagine it'd be gossipped about. |
| 18:55 | <@Tamber> | Not really anything worth getting the police involved in, then? |
| 18:55 | < Tarinaky> | It's pretty annoying because we've been kicking up a fuss about the president of the union making a remark blaming us for hacking the Union website (it was an automated attack injecting adverts for cialis etc...) |

| 20:02 | <&Derakon> | Okay, so. We have an experiment which is a sequence of actions. The experiment chops itself up into subsections based on the Executors that can perform the actions in those sections. |
| 20:03 | <&Derakon> | E.g. a 100-element experiment where the first 50 actions can be done by 1 Executor, then 1 action by another one, then the remaining 49 by the first one -- three subsections of size 50, 1, 49. |
| 20:03 | <&Derakon> | The bug here is that we're only getting image data for the first subsection; after that no more images arrive, and I don't know why. |

| 20:04 | <&Derakon> | AFAICT we don't change the camera state at any time after we start executing sections. |
| 20:04 | <&Derakon> | I can force the experiment to subdivide itself into finer intervals and get similar behavior, so it's not the actual actions that are causing the problem; it's the subdivision. |
| 20:05 | <&Derakon> | Best guess is that the executor isn't actually doing its job, but it certainly appears to be. |
| 20:06 | <&Derakon> | And this is where I'm stuck. |
| 20:09 | < ErikMesoy> | Is the first subsection hogging the camera without sending anything more? |
| 20:09 | | Kindamoody is now known as Kindamoody[zZz] |
| 20:10 | <&Derakon> | The device that executes subsections is just a signal source; it does not seize resources. |
| 20:10 | <&Derakon> | So it sends a digital "take a picture now" signal, then the camera takes a picture and forwards it to the cockpit. |
| 20:11 | <&Derakon> | The camera shouldn't care about the exact timing as long as signals don't arrive too close together. |
| 20:11 | < ErikMesoy> | Help me understand the architecture a bit more. Subsections send messages to camera which sends pictures to output? |
| 20:12 | <&Derakon> | We have three systems here. |
| 20:12 | <&Derakon> | Cockpit handles UI and telling some devices what to do. |
| 20:13 | <&Derakon> | Cameras receive images and send them to cockpit. |
| 20:13 | <&Derakon> | DSP acts as signal source to control cameras with strict timings. |
| 20:13 | <&Derakon> | We put the cameras into a "receiving" state. |
| 20:13 | <&Derakon> | In this state, every time they get a signal from the DSP, they take an image, and send it to the cockpit. |
| 20:14 | <&Derakon> | The DSP is handed a list of actions to execute -- this is the subsection. |
| 20:14 | <@froztbyte> | how are you actually doing the image transmission? |
| 20:14 | <&Derakon> | Pyro4 is a network comms library; I can send Numpy arrays through it. |
| 20:15 | <&Derakon> | s/network comms/remote object/ |
| 20:15 | <@froztbyte> | k |
| 20:15 | <@froztbyte> | and when you say subsections, do you mean like actual image slicing, or ... ? |
| 20:16 | <&Derakon> | No, the sections are sequences of commands handed to the DSP. They have nothing to do with the camera. |
| 20:16 | <&Derakon> | Like, one section says "open laser shutters at t=0; close shutters at t=10; activate cameras at t=11". |
| 20:16 | <&Derakon> | (For example) |
| 20:17 | <&Derakon> | Then another section says "open shutters at t=20; close shutters at t=30; activate cameras at t=31". |
| 20:17 | <@froztbyte> | okay |
| 20:17 | <&Derakon> | If I send everything as a single combined "section", then it executes correctly, but when I chop it up, it doesn't. |
| 20:18 | <@froztbyte> | so the handler/divider that splits the sections up into subsections, what's the structure for that like? |
| 20:18 | <@froztbyte> | pre and post hooks, input var, dumps out what it handled plus results? |
| 20:19 | <&Derakon> | http://pastebin.com/pUNua91N |
| 20:19 | <&Derakon> | Broadly, find the executor that can do the most lines in the action table, tell them to do it, repeat until we've completed the entire table. |
| 20:20 | <&Derakon> | You can ignore the stuff about multiple reps; self.numReps is 1 in this case. |
| 20:20 | <@froztbyte> | I'd starting dumping curIndex to a terminal or logfile |
| 20:20 | <@froztbyte> | look for patterns |
| 20:21 | <&Derakon> | No, you're looking in the wrong place. Note how I'm artificially forcing smaller subsections on line 17, for testing purposes. |
| 20:21 | <&Derakon> | The bug has nothing to do with where the division occurs. |
| 20:24 | <&Derakon> | Found it. |
| 20:24 | <&Derakon> | The problem was that the latter subsections hadn't rebased their timings. |
| 20:24 | <&Derakon> | So section 2's first event happens at t=30 instead of t=0. |
| 20:25 | <&Derakon> | But the DSP was also told that its entire execution should only take 29 time units (or whatever). |
| 20:25 | <&Derakon> | So it was stopping before doing anything. |
| 20:37 | <&Derakon> | Sorry about my tone there, froztbyte. I wasn't meaning to be dismissive. |
