Plorkyeran posted:mutation testing is totally awesome, but something that only .1% of projects will have any use for. there's no point in using some fancy tool to find code which is insufficiently tested when you can just look at your code coverage report and see that 30% of your code is never run at all. it is incrediby useful as an object lesson to people when they start writing tests (or write garbage tests) and chase 100% coverage you get what you measure, and if you don't have a metric to fight a metric you'll get all sorts of weird brain justifications to make the numbers go up

coffee cup "musings" so, if i rewrite my python io thing into a generator (which it kinda is but it's my own hot take continuity, not something ive seen real people do elsewhere), i can then/before migrate everything to 3.5 or later, and use async/await/other asynchronous buzzwords to achieve multithreading, or make decent steps towards it?

Blinkz0rz posted:i'm porting a piece of software we wrote in javascript to go as a proof of concept and it's not a great language to write in if you don't know the shape of your data until runtime languages that allow and whose standard libraries include heterogeneous maps (where keys can have different types of value) make dealing with this kind of stuff fairly straightforward if a language has ADTs you can get an equivalent effect with a bit more verbosity

fleshweasel posted:I don't know how you can write a program that operates on data whose shape you know jack poo poo about unless it's serialization or tree traversal or something else that really doesn't care how many attributes there are on a particular node or whatever, it just slurps them all up. the software coordinates and layers properties from a bunch of different sources and serves an endpoint for archaius so we can tune our services on the fly. nothing gets evaled so we basically just assemble a list of source properties then recursively mash them all together in the right order. the contents of the data are inconsequential as long as thet can be serialized to json, hence the reason we did this in javascript originally. there are other internal bits that are simple to model as types but the data being served is almost entirely unknown. every attempt i've made to rewrite this in another language has started with modeling most of the rest of the system and then stuff falls apart when i have to wrestle the language into dealing with unknown and semi-unstructured data

the best way to do it is render serverside w/ the server talking to the api on behalf of the client. oauth makes that very easy

Sapozhnik posted:i mean i'm still going to use it, i just feel like, you know, if this is the good framework (the single source of truth thing is actually a really good point you bring up) then god help anybody who has to work with something worse than that. it truly does get so much worse. maybe one of the reasons react isn't compelling to outsiders of the js world is that the reasons for it can't be illustrated with just TodoMVC or something. you have to work on giant piece of poo poo proprietary codebases with people who don't know what they're doing to truly understand all the need for over engineering. I use redux-saga pretty heavily and I love it. my best use case for it is wrapping this huge bloated 3rd party component I have to use. I use event channels to wrap its async initialization (it requires data from my server,which it uses in a call to a 3rd party api before it can be used) and to wrap the events that it fires while it's running. so I have a generator function that handles the entire lifecycle of the component as a synchronous-looking generator function that (1) waits for the user to navigate to the page where this component will be displayed (2) dispatches an event for the loading indicator (3) creates the initialization event channel (4) responds to the success/failure of initialization (5) on success, dispatch the loading done action (6) create the runtime event channel (7) forks the saga into two loops: (a) one that waits for 3rd party events and dispatches them to redux and (b) one that does poo poo to the component after certain redux actions its all pretty easy to read and follow, top to bottom. it manages to avoid both pyramid-looking callback hell as well as a need to jump around to more than one place in the codebase to understand the sequence. as far as the rest of the app is concerned its a nice black box where its just messages going in and out seemingly-synchronously.
