| 18:53:13 |  SolarDrew | I'm afraid I may have to skip it again this week |
| 18:53:47 | SolarDrew | I need to clean the fish tank, which I realise is not a great excuse but I just haven't had the time recently and it really needs doing |
| 18:54:21 |  Nick Murphy | No worries! I'm sure the fish will really appreciate it. |
| 18:55:18 | Nick Murphy | In any case I'm behind on all things PlasmaPy because of having to finish up a review article I'm co-authoring that is due on September 30, 2019. |
| 18:55:47 | SolarDrew | lol |
| 18:57:32 |  Dominik Stańczak | forgot as well! >_< I'm here though |
| 18:57:37 | Dominik Stańczak | * forgot as well! >_< I'm here though |
| 18:58:55 | Dominik Stańczak | this agenda link could come in handy |
| 19:45:25 | Nick Murphy | My internet connection got grumpy for a few minutes but I think the meeting may have ended. Oops! |
| 19:46:54 | Dominik Stańczak | Your connection status was green, we assumed you were in ninja mode due to some interruption or another |
| 19:47:27 | Dominik Stańczak | But yeah, not much more to discuss atm |
| 19:47:40 | Dominik Stańczak | I'll try to wrap some prs up over the weekend |

| 19:36:38 | Nick Murphy | Something I didn't know before now but is really cool: functools.partial |
| 19:37:50 | Nick Murphy | If you have a function for which you always want some of the args or kwargs to be specific values, then functools.partial will create a new function that freezes in the values that you provided for the args and kwargs |
| 19:42:05 | Dominik Stańczak | Yeah, it's handy |

| 16:07:59 | Dominik Stańczak | Apologies, but I will have to skip tomorrow's meeting due to the usual subjects of past procrastination and impending deadlines :( |

| 18:38:36 | Nick Murphy | A friendly reminder that we'll have our next community meeting in about 20 minutes at 19 UTC on PlasmaPy's Jitsi channel. Please feel free to edit our agenda and minutes. |

| 23:42:50 | Nick Murphy | Turns out that if you set the default for an argument to be a mutable object, and then you change it, then it will remain changed in future function calls. The reason (if I remember from what I read yesterday) is that the object is created only once, when the function is declared, so changes to that object persist. |
| 23:45:33 | Nick Murphy | The moral of the story is that we should not have lists or dictionaries as the default for a keyword argument. It's better to have the default be perhaps None, and then create a list or dictionary inside the function. |
| 23:50:44 |  rocco8773 | Make sense, even though this would not have naturally occurred to me. It's a good thing I've always preferred None, since None is more explicit/literal. Literally, nothing has been passed into the function. |

| 10:54:14 | Dominik Stańczak | yup |
| 10:57:24 | Dominik Stańczak | h5py wheels for 3.8 are out, and so we are green on 3.8 tests (check master)! |
| 17:17:49 | Nick Murphy | Awesome! I love it when things get fixed without having to do anything. 😺 |
