00:00:45.860 --> 00:00:50.920 I have never seen ZipApp in accent, but I have heard of ZipApp. 00:00:50.920 --> 00:00:53.200 And it is a very interesting idea. 00:00:53.200 --> 00:00:55.380 New in 3.5, so it's not that old, is it? 00:00:55.380 --> 00:00:56.760 3.5 still sounds new to me. 00:00:56.760 --> 00:00:58.260 I don't care what people say about dates. 00:00:58.880 --> 00:00:59.180 Really? 00:00:59.180 --> 00:01:01.020 It sounds new to me. 00:01:01.020 --> 00:01:02.780 It has async and await. 00:01:02.780 --> 00:01:09.800 And that's the first point where I feel like it's kind of as far back as you can go and still be modern Python. 00:01:09.800 --> 00:01:10.360 Okay. 00:01:10.360 --> 00:01:11.240 I think. 00:01:11.240 --> 00:01:12.740 Don't get f-strings, but come on. 00:01:12.740 --> 00:01:13.780 Still, it's not that old. 00:01:13.780 --> 00:01:15.300 It's not something that's better. 00:01:15.300 --> 00:01:17.360 You're more lenient than I am. 00:01:17.360 --> 00:01:19.920 I'm like a 3.7 is the start of the world. 00:01:19.920 --> 00:01:21.340 But anyway. 00:01:21.440 --> 00:01:21.620 Okay. 00:01:21.620 --> 00:01:23.900 So ZipApp, it's been around for a while. 00:01:23.900 --> 00:01:26.440 So all supported Pythons use it, right? 00:01:26.440 --> 00:01:34.740 So and but apparently there was like a flub up in the announcement when it came out. 00:01:34.740 --> 00:01:37.060 So people didn't quite see it when it came out. 00:01:37.060 --> 00:01:37.900 So it's anyway. 00:01:37.900 --> 00:01:40.600 So what it is, it's in the standard library. 00:01:40.600 --> 00:01:47.160 And it's a module that provides tools to managing the creation of zip files containing Python code. 00:01:47.560 --> 00:01:52.020 And they can be directly interpreted by the Python interpreter. 00:01:52.020 --> 00:01:54.440 So it's a command line interface and an API. 00:01:54.440 --> 00:02:01.000 But the deal is you kind of take like a package or Python package you got or a file or whatever. 00:02:01.000 --> 00:02:03.880 And it creates an executable for you. 00:02:03.880 --> 00:02:08.140 Well, it's not really an executable because it doesn't have the Python part. 00:02:08.140 --> 00:02:09.820 So you still have to run it with Python. 00:02:09.820 --> 00:02:11.940 But it includes all the stuff except for Python. 00:02:12.340 --> 00:02:16.700 It's kind of like if you could hand out just a Python script and say run this. 00:02:16.700 --> 00:02:19.420 But it has dependencies and it has a lot of structure. 00:02:19.420 --> 00:02:22.520 But you don't have to make people deal with that, right? 00:02:22.520 --> 00:02:27.940 You don't have to have them create virtual environments and install stuff because it can all just take the stuff it needs. 00:02:27.940 --> 00:02:30.580 I haven't played with it enough to know if it has. 00:02:30.580 --> 00:02:31.040 Oh, yeah. 00:02:31.040 --> 00:02:32.280 It has requirements too. 00:02:32.280 --> 00:02:36.780 Install all of your applications dependencies in the app directory using pip. 00:02:36.780 --> 00:02:40.500 So, yeah, so there's like a there's a thing. 00:02:40.500 --> 00:02:46.380 There's like a tutorial inside the documentation saying how to create a standalone application with zip app. 00:02:46.380 --> 00:02:48.580 So, yes, it includes your your dependencies. 00:02:48.580 --> 00:02:50.500 And then you just create this little thing. 00:02:50.500 --> 00:02:57.080 So you can say you can give it to somebody and say run this on Python 5 or, you know, or whatever you support. 00:02:57.080 --> 00:02:58.680 And that's pretty cool. 00:02:58.680 --> 00:03:00.500 It's got all that all bundled in. 00:03:00.500 --> 00:03:04.760 I haven't tried this yet, but I didn't even know this was here until recently. 00:03:04.760 --> 00:03:08.860 Brett Cannon mentioned PYZ files. 00:03:08.860 --> 00:03:11.340 And I'm like, what the heck is a PYZ file? 00:03:11.340 --> 00:03:12.740 And I looked it up. 00:03:12.740 --> 00:03:15.940 It's these Python zip app things. 00:03:15.940 --> 00:03:17.620 So interesting. 00:03:17.620 --> 00:03:18.700 Pretty neat. 00:03:18.700 --> 00:03:20.100 There's some examples in there. 00:03:20.100 --> 00:03:25.860 So, yeah, that's just I guess it's just if anybody was trying to think of some way, 00:03:25.860 --> 00:03:31.920 because we have talked about like lightweight ways to ship stuff to Python stuff to people. 00:03:31.920 --> 00:03:37.340 And I think it's fine to tell people to assume that most I mean, depending on your audience. 00:03:37.340 --> 00:03:41.340 But there's a lot of people that it's fine to say it's it's running Python. 00:03:41.340 --> 00:03:42.780 So you have to install Python. 00:03:42.780 --> 00:03:48.660 But then and it's easy to send a file, but sending a bunch of stuff is a little bit harder. 00:03:48.660 --> 00:03:52.840 I mean, you could if they're if they're developers, you can say, here's the repo. 00:03:53.040 --> 00:03:54.720 Just download it, install requirements. 00:03:54.720 --> 00:03:55.860 And there you go. 00:03:55.860 --> 00:03:58.760 But for a lot for a lot of people, that's a little too much. 00:03:58.760 --> 00:03:59.760 So this is kind of neat. 00:03:59.760 --> 00:04:07.100 The other use case that I think is a really cool one that I've seen is using it within CI CD pipeline. 00:04:07.100 --> 00:04:10.420 So if you have a stage that's that you want to you. 00:04:10.420 --> 00:04:13.020 All you're doing is pulling stuff in and running it anyway. 00:04:13.020 --> 00:04:15.200 Might as well just have it all zipped up already. 00:04:15.200 --> 00:04:16.400 So, yeah, it's cool. 00:04:16.400 --> 00:04:16.660 Cool. 00:04:16.660 --> 00:04:17.680 Yeah, it's super cool. 00:04:17.680 --> 00:04:19.160 Just a quick one. 00:04:19.160 --> 00:04:19.520 Yeah. 00:04:19.520 --> 00:04:22.920 Henry on the audience says Python can run zip apps files directly. 00:04:22.920 --> 00:04:26.340 PYZ files has been supported since well before 3.5. 00:04:26.340 --> 00:04:28.020 3.5 just makes it easier to do. 00:04:28.020 --> 00:04:28.740 Oh, really? 00:04:28.740 --> 00:04:29.180 OK. 00:04:29.180 --> 00:04:29.720 Yeah. 00:04:29.720 --> 00:04:30.540 Apparently. 00:04:30.540 --> 00:04:32.060 Yeah, I thought that that was true. 00:04:32.060 --> 00:04:33.820 But yeah, the zip app is really cool. 00:04:33.820 --> 00:04:34.320 Neat. 00:04:34.320 --> 00:04:34.980 Indeed. 00:04:34.980 --> 00:04:35.580 Cool. 00:04:35.580 --> 00:04:37.740 So, well, what do you have for us? 00:04:37.880 --> 00:04:46.780 I want to tell you all about maybe a use case or a story of like how you can just take Python and solve your own interesting little problems. 00:04:46.780 --> 00:04:56.880 So this comes unknowingly through Rhett Turnbull, who shared a blog post in sort of an interesting circular way over on Mastodon. 00:04:56.880 --> 00:05:03.820 It says, great blog post from EQ on reverse engineering the Apple News app with Python and nerd power. 00:05:04.180 --> 00:05:05.140 That sounds fun, right? 00:05:05.140 --> 00:05:05.700 Mm-hmm. 00:05:05.700 --> 00:05:08.140 So this is an article that you can check out. 00:05:08.140 --> 00:05:15.780 And basically it says, look, one way that's awesome to do a bunch of research and gather up a bunch of news is Apple News. 00:05:15.780 --> 00:05:18.460 And there's a way in Apple News to say read later. 00:05:18.460 --> 00:05:24.700 But because it's Apple News, it's like tries as much as possible to keep you within its little walled garden of Apple News. 00:05:24.860 --> 00:05:28.260 For example, if you share it with somebody, it doesn't share the original link. 00:05:28.260 --> 00:05:29.540 It shares the Apple News link. 00:05:29.540 --> 00:05:34.780 And, you know, if you want to access those links outside of the Apple News app, well, nope, you don't get that, right? 00:05:34.780 --> 00:05:43.320 And so this EQ person, who is the nickname or online name of Dave Bullock, says, let's see. 00:05:43.320 --> 00:05:45.420 I reached out to Rhett Turnbull. 00:05:45.420 --> 00:05:56.260 Here's the circular bit about his OXX or macOS photos Python library that he had been using to extract data from photos, which have a similar issue. 00:05:56.260 --> 00:06:02.100 And says, you seem to be familiar with like ripping stuff out of the internal of these macOS apps. 00:06:02.440 --> 00:06:03.500 What about this one? 00:06:03.500 --> 00:06:14.120 And it got a few hints and turned out that I was able to pull in some information to actually get the Apple News link out of a list of saved relator things hidden somewhere. 00:06:14.120 --> 00:06:21.560 And then goes through using Python to actually Python plus beautiful soup to pull that out into something that is meaningful. 00:06:21.560 --> 00:06:24.640 And you can actually share with folks, which is pretty cool. 00:06:24.640 --> 00:06:28.520 And then it said, well, I shared this back with Rhett and Rhett's like, oh, that's awesome. 00:06:28.800 --> 00:06:34.480 How about I create a whole CLI library that lets people do that and stash it into a SQLite one? 00:06:34.480 --> 00:06:38.720 And then who knows, maybe you connect that to dataset from Simon Willison. 00:06:38.720 --> 00:06:41.060 And, you know, like it just it can just go from there. 00:06:41.060 --> 00:06:45.740 So there's Apple News to SQLite as a CLI that came out of this whole journey. 00:06:45.740 --> 00:06:54.040 But I just thought it was a really cool use case of like, look, you don't need to be trying to create the next major API service or the major web app. 00:06:54.040 --> 00:06:56.200 Here's just a fun way to like, I've got this problem. 00:06:56.200 --> 00:06:59.900 I've got the structured data and maybe Python can solve my problem here. 00:06:59.900 --> 00:07:01.340 Yeah, usually can. 00:07:01.340 --> 00:07:01.800 Yeah. 00:07:01.800 --> 00:07:03.240 Anyway, a lot of fun. 00:07:03.240 --> 00:07:04.160 People can check this out. 00:07:04.200 --> 00:07:13.900 And I think if you're looking for ways to get better with Python or practice with Python or do interesting little projects, maybe this will inspire you because it's it's not a ton of work for this. 00:07:13.900 --> 00:07:14.080 Right. 00:07:14.080 --> 00:07:14.540 Yeah. 00:07:14.540 --> 00:07:16.400 We need nerd power t-shirts. 00:07:16.400 --> 00:07:17.280 Nerd power. 00:07:17.280 --> 00:07:17.900 I think. 00:07:17.900 --> 00:07:18.260 Nerd. 00:07:18.260 --> 00:07:19.280 Oh, yes. 00:07:19.600 --> 00:07:25.040 I got some t-shirt stuff to share with you at the end as part of our joke. 00:07:25.040 --> 00:07:27.420 So I don't know if there's a nerd power one out there. 00:07:27.420 --> 00:07:28.840 Just real quickly on the audience. 00:07:28.840 --> 00:07:35.700 Fabio asks, a while ago, I talked about a testing a paid search engine that was Kagi that I've been using. 00:07:35.700 --> 00:07:36.680 I'm still using Kagi. 00:07:36.680 --> 00:07:38.620 I've been enjoying Kagi a lot. 00:07:38.620 --> 00:07:39.600 So that's the one. 00:07:39.600 --> 00:07:43.460 Brian, we ready to tell folks about our sponsor before we move on? 00:07:43.460 --> 00:07:44.720 I think that's a good idea. 00:07:44.720 --> 00:07:45.920 I do as well. 00:07:45.920 --> 00:07:49.000 And as promised, I got something fun for you this time. 00:07:49.000 --> 00:07:52.360 So remember, this one is brought to you by Microsoft for Startup Founders Hub. 00:07:52.360 --> 00:08:00.140 One of the really important things you get is access to the open access and credits to the OpenAI APIs and the Azure OpenAI service. 00:08:00.140 --> 00:08:05.900 So I said, hey, let's take the boring or in the straightforward ad that we had written originally. 00:08:05.900 --> 00:08:08.760 And I asked OpenAI to rewrite it. 00:08:08.760 --> 00:08:15.340 So I said, hey, OpenAI, can you rewrite the Founders Hub ad as an American football coach trying to motivate his team? 00:08:15.340 --> 00:08:16.780 So where do we get back? 00:08:16.780 --> 00:08:18.300 Attention all startup founders. 00:08:18.480 --> 00:08:19.540 This is a call to action. 00:08:19.540 --> 00:08:21.280 Are you ready to reach the next level?

00:09:34.920 --> 00:09:42.180 I do, but just an interesting suggestion from the audience of would it be different if Ted Lasso wrote it? 00:09:42.180 --> 00:09:43.120 Oh, I bet it would. 00:09:43.120 --> 00:09:45.500 Well, you know, there's always next week. 00:09:45.500 --> 00:09:48.040 Yeah. 00:09:48.040 --> 00:09:50.620 So let's talk about context managers. 00:09:50.620 --> 00:10:01.100 So I have used, I love context managers, and I've used context lib, context manager decorator to create context managers. 00:10:01.100 --> 00:10:07.580 And if you've never tried it, it's like the easiest way to make a context manager. 00:10:07.580 --> 00:10:16.480 With context manager, you decorate a function with the decorator context manager, and then you put a yield in the middle of it or anywhere in it. 00:10:16.480 --> 00:10:17.380 It can even loop. 00:10:17.380 --> 00:10:19.420 Wait, maybe it can't loop. 00:10:19.420 --> 00:10:20.540 No, that's something else. 00:10:20.540 --> 00:10:21.900 That's a generator. 00:10:22.520 --> 00:10:30.440 No, context manager, you put a yield in it, but it can be in the middle of like an exception block or tri-accept or something else. 00:10:30.440 --> 00:10:36.560 And then, so it runs the first part, and then after the width block, it tears it down with the teardown. 00:10:36.560 --> 00:10:37.220 It's nice. 00:10:37.220 --> 00:10:41.580 I knew about this, but then I was reading an article from Trey Hunter. 00:10:41.580 --> 00:10:43.940 What is a context manager? 00:10:43.940 --> 00:10:48.280 And it's actually a really kind of nice article that talks about all the stuff. 00:10:48.280 --> 00:10:53.080 Basically, if you didn't have it, so first off, it tells you what a context manager is. 00:10:53.080 --> 00:10:57.880 And one of the ones that people are most familiar with maybe is open file as F. 00:10:57.880 --> 00:11:04.660 So with open file as F or any with block, you're using a context manager, right? 00:11:04.660 --> 00:11:08.040 So opening file is great because then it closes afterwards. 00:11:08.840 --> 00:11:12.380 And then he talks through some things. 00:11:12.380 --> 00:11:16.940 One of the next example he brings up is context lib change dir. 00:11:16.940 --> 00:11:25.220 And I don't know how I didn't know this was here, but what it does is if you use with change dir, it changes your directory. 00:11:25.220 --> 00:11:28.260 But then when you're done with the width block, it goes back. 00:11:28.260 --> 00:11:29.300 Cool. 00:11:29.300 --> 00:11:30.380 Somehow I missed that. 00:11:30.380 --> 00:11:33.240 So I was going in and looking, and there's a whole bunch of other stuff. 00:11:33.240 --> 00:11:36.720 So I did know about closing. 00:11:37.340 --> 00:11:50.020 So like the file open thing, you can anything that has a close statement in it, you can use the context manager closing to use like for line and page. 00:11:50.020 --> 00:11:50.500 Wait. 00:11:50.500 --> 00:11:59.360 With closing URL open as an example, because then when you're done for URL lib, it closes it. 00:11:59.360 --> 00:12:03.280 So anything that has a, you have to do a close command afterwards, you can use closing. 00:12:03.560 --> 00:12:04.360 That's cool. 00:12:04.360 --> 00:12:07.260 But there's a, there's async closing also. 00:12:07.260 --> 00:12:07.800 Cool. 00:12:07.800 --> 00:12:09.320 There's a bunch. 00:12:09.320 --> 00:12:10.160 There's suppress. 00:12:10.160 --> 00:12:17.860 So if for a part of your code, you want to suppress a particular possible exception, you can suppress it for a little bit of your code. 00:12:17.860 --> 00:12:18.940 Super handy. 00:12:18.940 --> 00:12:23.760 Redirect standard out, but just for a little while, you can do that. 00:12:23.840 --> 00:12:27.980 Just there's, and then in really extended error. 00:12:27.980 --> 00:12:30.840 And then there's, there's our changed error, but there's a bunch of stuff in here. 00:12:30.840 --> 00:12:37.200 So I guess I encourage people to go through the, go look at the context lib and look at some of the stuff you can do. 00:12:37.200 --> 00:12:39.080 Cause there's a lot of great stuff there. 00:12:39.080 --> 00:12:39.840 So neat. 00:12:39.840 --> 00:12:40.840 That is really neat. 00:12:40.840 --> 00:12:42.880 I am a huge fan of these types of things. 00:12:42.880 --> 00:12:44.220 And hold on, don't scroll anymore. 00:12:44.220 --> 00:12:46.880 Do you see when a changed or came into existence? 00:12:46.880 --> 00:12:48.340 3.11. 00:12:48.340 --> 00:12:49.380 3.11. 00:12:49.840 --> 00:12:51.360 That might be why we don't know about it. 00:12:51.360 --> 00:12:52.100 Cause that's brand new. 00:12:52.100 --> 00:12:52.740 Yeah. 00:12:52.740 --> 00:12:53.820 Nice. 00:12:53.820 --> 00:12:58.940 But I love these types of things we say for this block of code, I want something to be true. 00:12:58.940 --> 00:13:01.560 And then afterwards, I don't want to think about how it happens. 00:13:01.560 --> 00:13:05.140 Like however I get out of here, early return, exception, done, whatever. 00:13:05.140 --> 00:13:06.900 Just undo the thing. 00:13:06.900 --> 00:13:07.600 Yeah. 00:13:07.600 --> 00:13:08.720 Really, really nice. 00:13:08.720 --> 00:13:16.880 I use some of these, I mean, not, I don't know of a built-in one for this, but that with colorama to say during this section, I want all the output to be this color. 00:13:16.880 --> 00:13:22.020 And then no matter how I leave, roll it back, the default for like text output and things like that. 00:13:22.020 --> 00:13:22.280 Right. 00:13:22.280 --> 00:13:23.420 Oh, neat. 00:13:23.420 --> 00:13:24.880 Otherwise you got to keep resetting. 00:13:24.880 --> 00:13:25.620 Like, oh, I'm returning here. 00:13:25.620 --> 00:13:27.020 So I got to reset here and here. 00:13:27.020 --> 00:13:28.060 And it's just like, nope. 00:13:28.060 --> 00:13:29.560 In this block, it's blue. 00:13:29.560 --> 00:13:30.620 Now it's not blue. 00:13:30.620 --> 00:13:31.040 Right. 00:13:31.040 --> 00:13:31.880 Those kinds of things. 00:13:31.880 --> 00:13:32.680 I just love it. 00:13:32.680 --> 00:13:35.860 So having these built in, I didn't realize there are so many built in. 00:13:35.860 --> 00:13:36.300 This is great. 00:13:36.300 --> 00:13:36.720 Yeah. 00:13:36.720 --> 00:13:38.280 That's a cool use case. 00:13:38.280 --> 00:13:39.000 I like that. 00:13:39.000 --> 00:13:39.540 Yeah. 00:13:39.540 --> 00:13:40.220 Thanks. 00:13:40.220 --> 00:13:41.360 Indeed. 00:13:41.360 --> 00:13:41.640 Indeed. 00:13:41.640 --> 00:13:41.800 Indeed. 00:13:41.800 --> 00:13:49.040 So this next item here that I got for us, Brian, this is a follow-up to a question. 00:13:49.040 --> 00:13:53.440 When you talked about Knox, somebody asked, can I use that with poetry? 00:13:53.440 --> 00:13:56.880 And we didn't know for sure, but you can bet the audience knows. 00:13:56.880 --> 00:13:57.400 Yeah. 00:13:58.180 --> 00:13:58.660 Yeah. 00:13:58.660 --> 00:14:05.280 So yes, in fact, there is a Knox-poetry library that you can use. 00:14:05.280 --> 00:14:07.040 And it's super simple. 00:14:07.040 --> 00:14:12.960 So the way Knox works, quick reminder for folks who maybe didn't listen or didn't listen that 00:14:12.960 --> 00:14:17.120 closely or just forgot from last week is you create a session for some operation. 00:14:17.120 --> 00:14:20.860 And you say, this session is going to run Python 3.10 or 3.9 together. 00:14:20.860 --> 00:14:21.120 Right. 00:14:21.340 --> 00:14:23.680 And then you just say, session install what you need to. 00:14:23.680 --> 00:14:29.540 For example, here, the example on this page says, install pytest and install the local package 00:14:29.540 --> 00:14:31.820 that you're working with plus its dependencies. 00:14:31.820 --> 00:14:33.500 And then run pytest. 00:14:33.500 --> 00:14:35.740 The problem was, there's a couple issues. 00:14:35.740 --> 00:14:44.060 If you don't have something that understands poetry, then you end up, the package with just 00:14:44.060 --> 00:14:47.960 the wheel metadata and not the lock file gets installed, which means you don't get the 00:14:47.960 --> 00:14:53.060 pinned versions installed that you're hoping for, the dependency constraints that you're 00:14:53.060 --> 00:14:53.600 hoping for. 00:14:53.600 --> 00:14:55.800 You just get whatever the latest of those are. 00:14:55.800 --> 00:14:58.220 pytest wouldn't be constrained. 00:14:58.220 --> 00:15:02.160 Poetry would be installed as a build backend every time. 00:15:02.160 --> 00:15:04.340 There's just a bunch of stuff that's a little bit lumsier. 00:15:04.340 --> 00:15:10.000 So what you get here is you basically get a library that you say, sort of from Knox import 00:15:10.000 --> 00:15:12.460 session, you say from Knox poetry import session. 00:15:12.460 --> 00:15:18.200 And this is a wrapper proxy to the underlying Knox session that configures things to make 00:15:18.200 --> 00:15:19.140 sure that poetry works. 00:15:19.140 --> 00:15:24.880 So for example, the install will use the lock file that poetry uses and other types of things. 00:15:24.880 --> 00:15:25.600 There's a bunch of stuff. 00:15:25.600 --> 00:15:27.840 It'll build the wheel from the local package. 00:15:27.840 --> 00:15:33.220 It'll install the wheel as a pytest package and then invoke pytest to run the test against 00:15:33.220 --> 00:15:33.980 that installation. 00:15:33.980 --> 00:15:34.860 That's pretty cool. 00:15:35.180 --> 00:15:40.280 So it also has some other types of things that you can put on it here. 00:15:40.280 --> 00:15:41.020 Where do they go? 00:15:41.020 --> 00:15:43.460 There's a bunch of poetry specific things. 00:15:43.460 --> 00:15:45.280 You can say session dot poetry dot. 00:15:45.280 --> 00:15:46.560 There it is. 00:15:46.560 --> 00:15:52.500 Like session dot poetry dot install root or session dot poetry dot build package as a wheel 00:15:52.500 --> 00:15:54.320 or a disk and export requirements. 00:15:54.320 --> 00:15:55.160 All these different things. 00:15:55.160 --> 00:15:59.640 If you want to leverage the fact that it is actually poetry or you can just use this wrapper 00:15:59.640 --> 00:16:03.220 and write exactly the same code, but it now works correctly with your project. 00:16:03.640 --> 00:16:04.000 Oh, nice. 00:16:04.000 --> 00:16:04.460 Yeah. 00:16:04.460 --> 00:16:04.800 I like it. 00:16:04.800 --> 00:16:11.300 This is from, came to us from not one, but two people said, hey, you guys, John Hagen and 00:16:11.300 --> 00:16:12.040 Mark Pruitt. 00:16:12.040 --> 00:16:15.700 So thank you both for sending in your particular use cases for that. 00:16:15.700 --> 00:16:25.420 And it also comes to us from Claudio Jolowitz, who created the hyper modern Python project cookie 00:16:25.420 --> 00:16:25.700 cutter. 00:16:25.700 --> 00:16:28.400 And this is part of that to support that project. 00:16:28.400 --> 00:16:33.120 I actually had him on Python a little while ago, back in about a year ago. 00:16:33.340 --> 00:16:35.020 Do you want to hear way more about this? 00:16:35.020 --> 00:16:38.100 We probably even talked about this in passing and I was like, oh, okay. 00:16:38.100 --> 00:16:38.460 Interesting. 00:16:38.460 --> 00:16:39.380 Like didn't really. 00:16:39.380 --> 00:16:42.140 So yeah, there it is. 00:16:42.140 --> 00:16:46.220 We hear so many things like sometimes, you know, it doesn't always stick the first time, 00:16:46.220 --> 00:16:46.860 even though we try. 00:16:46.860 --> 00:16:48.320 Yeah, that happens. 00:16:48.320 --> 00:16:49.200 It does happen. 00:16:49.200 --> 00:16:49.900 All right. 00:16:49.900 --> 00:16:54.120 And it also happens that we are at the end of our main topics, but you got any extras you 00:16:54.120 --> 00:16:54.440 want to share? 00:16:54.440 --> 00:16:55.140 I do. 00:16:55.240 --> 00:16:59.080 And it kind of talks about it's a little bit similar to what we're just talking about. 00:16:59.080 --> 00:17:01.480 So I was just at Pike Cascades this weekend. 00:17:01.480 --> 00:17:03.700 This last weekend just got back. 00:17:03.700 --> 00:17:05.080 I took the train back yesterday. 00:17:05.080 --> 00:17:06.440 It's a lovely ride. 00:17:06.440 --> 00:17:06.580 How was the train ride? 00:17:06.580 --> 00:17:07.560 Did you enjoy it? 00:17:07.640 --> 00:17:09.480 Well, I did on the way back. 00:17:09.480 --> 00:17:14.360 On the way there, I kind of thought I would be able to sleep, but I didn't. 00:17:14.360 --> 00:17:15.320 I wasn't able to. 00:17:15.320 --> 00:17:20.920 So on the way back, it's a nine hour drive or nine hour train ride from eight or nine from 00:17:20.920 --> 00:17:22.000 here to Vancouver. 00:17:22.500 --> 00:17:24.360 On the way back, I'm like, I'll just work. 00:17:24.360 --> 00:17:27.540 So I just edited a bunch of audio. 00:17:27.540 --> 00:17:29.620 So I was working the whole way back. 00:17:29.620 --> 00:17:30.020 It's great. 00:17:30.020 --> 00:17:36.500 But one of the things that happened to me there was a couple of people saying, oh, yeah, we 00:17:36.500 --> 00:17:36.800 met. 00:17:36.800 --> 00:17:41.980 I was at, you know, I was at Picon, Portland or Ohio or something like that. 00:17:41.980 --> 00:17:42.400 We met. 00:17:42.400 --> 00:17:43.640 I'm like, that's wonderful. 00:17:43.640 --> 00:17:46.380 I meet so many people and I have such a bad memory. 00:17:46.380 --> 00:17:50.640 I mean, I trust and I don't I feel bad about not remembering everybody I ran into. 00:17:50.640 --> 00:17:56.220 Anyway, I'm sorry if I if I said hi and introduced myself and you already we already have done 00:17:56.220 --> 00:17:56.460 that. 00:17:56.460 --> 00:17:57.060 My apologies. 00:17:57.060 --> 00:17:57.920 I'm bad at it. 00:17:57.920 --> 00:17:59.440 It's not ideal. 00:17:59.440 --> 00:18:01.200 It's also not personal. 00:18:01.200 --> 00:18:02.560 People sometimes take it personally. 00:18:02.560 --> 00:18:05.300 It's like, well, it's really hard when you meet 400 people. 00:18:05.300 --> 00:18:05.800 Yeah. 00:18:05.800 --> 00:18:09.100 And then also the questions of you talked about this one thing. 00:18:09.100 --> 00:18:10.040 It was kind of like that. 00:18:10.040 --> 00:18:10.940 What was that again? 00:18:10.940 --> 00:18:12.720 Like, sorry. 00:18:12.720 --> 00:18:16.440 That's why I have Google or search or whatever. 00:18:16.440 --> 00:18:19.080 So I did give a talk and it's great. 00:18:19.080 --> 00:18:25.560 The the slides are up at Python test dot com slash I cascades 2023. 00:18:25.560 --> 00:18:28.600 And there are they are going to chop up the videos. 00:18:28.600 --> 00:18:31.640 And I think that's what they've told me that they're going to chop up the videos. 00:18:31.640 --> 00:18:33.860 But for now, the day one and day two is available. 00:18:33.860 --> 00:18:38.820 If you really want to watch mine, it's about sharing pytest figure fixtures. 00:18:39.820 --> 00:18:47.140 It's at what hour 22 hours, 40 minutes, 58 seconds approximately on day two. 00:18:47.140 --> 00:18:50.480 But that exact link is in our show notes as well. 00:18:50.480 --> 00:18:54.660 If you want to click through and watch 25 minutes of me talking about packaging. 00:18:54.660 --> 00:18:56.700 So it was really fun. 00:18:56.700 --> 00:18:57.800 I had a good time. 00:18:58.200 --> 00:18:59.960 Do you have any extras? 00:18:59.960 --> 00:19:02.340 Today is talk Python's birthday. 00:19:02.340 --> 00:19:04.260 I believe you got to do math. 00:19:04.260 --> 00:19:06.620 I think it's eight years old, which is nuts. 00:19:06.620 --> 00:19:07.640 It's either seven or eight. 00:19:07.640 --> 00:19:08.660 That's nuts. 00:19:08.660 --> 00:19:14.340 But the reason I thought of that is the latest episode right now is Python tips and tricks for better testing. 00:19:14.340 --> 00:19:17.060 That also brings into some of the stuff that you talked about your talk. 00:19:17.060 --> 00:19:21.580 So if people are interested, they should check out this episode and they can see a cool hat. 00:19:21.720 --> 00:19:22.160 Nice. 00:19:22.160 --> 00:19:24.500 Cool. 00:19:24.500 --> 00:19:25.080 All right. 00:19:25.080 --> 00:19:28.640 That's not what I was planning on sharing, but yeah, it ties right in there. 00:19:28.640 --> 00:19:32.180 Now, what I wanted to share was one thing. 00:19:32.180 --> 00:19:36.520 So let me tell you about my router challenges here. 00:19:36.520 --> 00:19:39.920 So at my, as you know, Brian, but probably almost no one else does. 00:19:39.920 --> 00:19:42.060 I have my office above my garage. 00:19:42.060 --> 00:19:48.240 My garage is a separate building from my house and there's no Ethernet connecting this as much as I've tried to make that happen. 00:19:48.240 --> 00:19:49.420 I haven't been able to make it happen. 00:19:49.420 --> 00:19:52.560 So I'm like, well, how do I make this faster? 00:19:52.560 --> 00:19:56.080 I've been using a two node mesh network. 00:19:56.080 --> 00:19:59.920 And it turns out that people getting stuff around us have been causing a lot of interference. 00:19:59.920 --> 00:20:04.380 And so my wife needs one closer to her office and I need one closer to mine. 00:20:04.380 --> 00:20:05.760 And one's got to be plugged into the internet. 00:20:05.760 --> 00:20:08.840 And we were like kind of like disagreeing. 00:20:08.840 --> 00:20:10.000 Like I want it closer to my office. 00:20:10.000 --> 00:20:10.760 No closer to mine. 00:20:10.760 --> 00:20:11.780 Mine's a separate building. 00:20:11.780 --> 00:20:12.320 I need more. 00:20:12.320 --> 00:20:12.540 Right. 00:20:12.540 --> 00:20:14.540 And, and back and forth. 00:20:14.540 --> 00:20:17.560 And so I ended up solving this with too much money. 00:20:17.560 --> 00:20:22.060 I'm getting this thing called the Atlas Max 6E length this router. 00:20:22.060 --> 00:20:31.140 I don't know if I recommend it because it's really expensive, but it's one of the few things that both has three nodes and it's 6E Wi-Fi, not just Wi-Fi 6. 00:20:31.480 --> 00:20:31.640 Right. 00:20:31.640 --> 00:20:32.640 Good combo. 00:20:32.640 --> 00:20:34.480 So this is not really my recommendation. 00:20:34.480 --> 00:20:35.420 What I want to tell you about. 00:20:35.420 --> 00:20:45.780 My recommendation is I've always considered these mesh network things to be like, well, if I'm on Wi-Fi and that talks to one of the nodes and then the node talks to the main node at the house. 00:20:45.780 --> 00:20:47.740 That's, that's just as good. 00:20:47.820 --> 00:20:51.580 Like why would I ever say plug in ethernet to the secondary node, right? 00:20:51.580 --> 00:20:52.480 Still Wi-Fi. 00:20:52.480 --> 00:20:53.420 It's just one more hop, right? 00:20:53.420 --> 00:20:55.740 Well, I was getting a little interference in the house. 00:20:55.740 --> 00:21:04.360 I said, well, let me just try plugging in not to the thing that connects to the internet, but to the node that wirelessly across the buildings connects to the other thing that connects to the internet. 00:21:04.360 --> 00:21:05.520 Do you know what I learned? 00:21:05.520 --> 00:21:13.020 I learned something insane that I don't know if I can simulate it here across buildings. 00:21:13.020 --> 00:21:15.600 I'm apparently not getting it right now. 00:21:16.020 --> 00:21:20.760 I'm only getting a rough 570 megabit over wireless across buildings. 00:21:20.760 --> 00:21:23.520 Earlier, I was getting 800 megabit over Wi-Fi. 00:21:23.520 --> 00:21:26.420 Well, I mean, you're also streaming video at the same time. 00:21:26.420 --> 00:21:28.640 Yeah, we're streaming video and doing other stuff, right? 00:21:28.640 --> 00:21:29.300 Uploading, downloading. 00:21:29.300 --> 00:21:38.080 But so my advice to people, if you have a mesh network, even though you're connected to one of these nodes, you think, well, that's wireless to the end anyway. 00:21:38.080 --> 00:21:40.060 Like, is it really worth ethernet? 00:21:40.060 --> 00:21:40.740 Yes. 00:21:40.740 --> 00:21:43.180 It's because.net. 00:21:43.180 --> 00:21:44.080 I'll try one more. 00:21:44.080 --> 00:21:47.760 I was completely blown away by how much of a difference it makes. 00:21:47.760 --> 00:21:52.720 But yeah, it's really, really impressive to plug into these wireless things. 00:21:52.720 --> 00:21:56.020 So if you've got a mesh network, try ethernet to it, even if it doesn't matter. 00:21:56.020 --> 00:21:57.580 That's my extra. 00:21:57.580 --> 00:21:58.160 Cool. 00:21:58.160 --> 00:21:58.620 Yeah. 00:21:58.880 --> 00:22:00.060 I had to look it up. 00:22:00.060 --> 00:22:02.500 I didn't know what Wi-Fi 6E was. 00:22:02.500 --> 00:22:04.420 So I looked it up. 00:22:04.420 --> 00:22:06.040 It's 11AX. 00:22:06.040 --> 00:22:06.960 That makes sense. 00:22:07.600 --> 00:22:13.480 So I test Wi-Fi stuff, but I'm testing it on the standard side. 00:22:13.480 --> 00:22:18.140 So we get it before they decide what the buzzwords are going to be. 00:22:18.140 --> 00:22:18.900 Yeah. 00:22:18.900 --> 00:22:19.440 I see. 00:22:19.440 --> 00:22:20.100 Okay. 00:22:20.100 --> 00:22:20.680 Yeah. 00:22:20.680 --> 00:22:21.160 That's really cool. 00:22:21.280 --> 00:22:23.020 AX is really cool. 00:22:23.020 --> 00:22:27.000 It's one of the, it's the first standard that, I mean, that is, now I'm getting nerding out 00:22:27.000 --> 00:22:30.880 on Wi-Fi, but it's the first standard that's not bi-directional the same. 00:22:31.120 --> 00:22:38.500 So the protocol from up from the node to your device is different than the other way. 00:22:38.500 --> 00:22:40.820 Kind of like cellular is like that too. 00:22:40.820 --> 00:22:45.500 But before AX, it was identical. 00:22:45.500 --> 00:22:51.540 The same sort of protocol and traffic and speed and everything from in both directions. 00:22:51.540 --> 00:22:52.540 But this way. 00:22:52.540 --> 00:22:53.000 Yeah. 00:22:53.000 --> 00:22:54.180 So anyway. 00:22:54.180 --> 00:22:55.060 So neat. 00:22:55.060 --> 00:22:55.540 Yeah. 00:22:55.540 --> 00:22:56.520 Anyway, really, really cool. 00:22:56.520 --> 00:22:59.840 Out in the audience, David Poole says, Linksys makes good stuff. 00:23:00.340 --> 00:23:01.880 Wired is always better than wireless. 00:23:01.880 --> 00:23:03.540 I work on Wi-Fi professionally. 00:23:03.540 --> 00:23:04.460 Yeah, for sure. 00:23:04.460 --> 00:23:04.880 Yeah. 00:23:04.880 --> 00:23:05.400 All right. 00:23:05.400 --> 00:23:06.040 Nice. 00:23:06.040 --> 00:23:07.120 Ready for some jokes? 00:23:07.120 --> 00:23:08.100 Yeah. 00:23:08.100 --> 00:23:10.780 So I'm going to take us to an unexpected place. 00:23:10.780 --> 00:23:11.420 Etsy. 00:23:11.420 --> 00:23:12.460 You ready for this? 00:23:12.460 --> 00:23:17.620 Now, this is pretty, I considered not putting this here because it's fairly graphical. 00:23:17.620 --> 00:23:19.680 Like, you need to see it in nature. 00:23:19.680 --> 00:23:23.300 So what I'm going to do is I'm going to take our favorite one and put it as a chapter art 00:23:23.300 --> 00:23:24.220 for people to appreciate. 00:23:24.220 --> 00:23:24.560 Okay. 00:23:24.560 --> 00:23:25.140 Okay. 00:23:25.140 --> 00:23:31.440 So these are like tech signs that have words or sayings that don't necessarily match 00:23:31.440 --> 00:23:32.780 with what you might expect. 00:23:32.780 --> 00:23:37.620 So for example, here's one and it looks kind of like a RAM chip that's hot or something. 00:23:37.620 --> 00:23:39.320 And it has a little heat wave coming up. 00:23:39.320 --> 00:23:43.020 It says, caution, magic smoke cannot be reinserted once released. 00:23:43.020 --> 00:23:46.180 Isn't that awesome? 00:23:46.180 --> 00:23:47.000 Yeah. 00:23:47.440 --> 00:23:47.680 Yeah. 00:23:47.680 --> 00:23:48.360 Here's one. 00:23:48.360 --> 00:23:50.980 This is a throwback to quantum mechanics, I believe. 00:23:50.980 --> 00:23:53.920 It's a little wavy hexagonal lines and a bunch of question marks. 00:23:53.920 --> 00:23:54.720 It's uncertainty. 00:23:54.720 --> 00:23:56.260 Do not attempt to measure. 00:23:56.260 --> 00:23:59.900 This one, I think probably all of us can relate to this. 00:23:59.900 --> 00:24:02.620 I've created some of this myself and had to deal with it. 00:24:02.620 --> 00:24:05.420 It's a hexagon with some piece of technology in the middle. 00:24:05.420 --> 00:24:07.760 It says, caution, cursed technology inside. 00:24:07.760 --> 00:24:08.700 Oh, yeah. 00:24:08.700 --> 00:24:10.060 It's a pentagon in there. 00:24:10.060 --> 00:24:10.420 Cool. 00:24:10.420 --> 00:24:10.920 Nice. 00:24:10.920 --> 00:24:11.280 Yeah. 00:24:11.280 --> 00:24:11.520 Yeah. 00:24:11.520 --> 00:24:12.120 Pentagon rather. 00:24:12.120 --> 00:24:12.620 Thank you. 00:24:12.620 --> 00:24:14.380 And let's see. 00:24:14.380 --> 00:24:16.480 Maybe one more here. 00:24:16.980 --> 00:24:18.140 If we can find it. 00:24:18.140 --> 00:24:18.900 Oh, this one. 00:24:18.900 --> 00:24:19.780 This will be a good one. 00:24:19.780 --> 00:24:20.520 A Gen 2 one. 00:24:20.520 --> 00:24:21.900 It's got a Gen 2 logo in the middle. 00:24:21.900 --> 00:24:26.600 It says, warning, kernel may need recompiling in order to change sound volume. 00:24:26.600 --> 00:24:30.820 All right. 00:24:30.820 --> 00:24:32.540 Well, there you have it, folks. 00:24:32.540 --> 00:24:33.540 That's one of my jokes. 00:24:33.540 --> 00:24:34.740 There's a whole bunch of these. 00:24:34.740 --> 00:24:36.980 You can click around and enjoy them for a while. 00:24:36.980 --> 00:24:38.080 They're pretty good. 00:24:38.080 --> 00:24:38.480 Nice. 00:24:38.480 --> 00:24:39.320 These are great. 00:24:39.320 --> 00:24:39.840 They are. 00:24:39.840 --> 00:24:40.220 Cool. 00:24:40.220 --> 00:24:41.580 Well, thanks again. 00:24:41.580 --> 00:24:42.560 Wonderful episode. 00:24:42.560 --> 00:24:43.320 Sure was. 00:24:43.320 --> 00:24:44.700 Thank you, Brian, for being here. 00:24:44.700 --> 00:24:46.360 And thank you, everyone, for listening. 00:24:46.460 --> 00:24:47.040 Really appreciate it.
