kandi X-RAY | exhaustive Summary
The exhaustive package and command line program can be used to detect enum switch statements that are not exhaustive. An enum switch statement is exhaustive if it has cases for each of the enum's members. See godoc for the definition of enum used by the program. The exhaustive package provides an Analyzer that follows the guidelines described in the go/analysis package; this makes it possible to integrate into existing analysis driver programs.

QUESTION
I am working on a p2p application and to make testing simple, I am currently using udp broadcast for the peer discovery in my local network. Each peer binds one udp socket to port 29292 of the ip address of each local network interface (discovered via GetAdaptersInfo) and each socket periodically sends a packet to the broadcast address of its network interface/local address. The sockets are set to allow port reuse (via setsockopt SO_REUSEADDR), which enables me to run multiple peers on the same local machine without any conflicts. In this case there is only a single peer on the entire network though.
This all works perfectly fine (tested with 2 peers on 1 machine and 2 peers on 2 machines) UNTIL a network interface is disconnected. When deactivacting the network adapter of either my wifi or an USB-to-LAN adapter in the windows dialog, or just plugging the usb cable of the adapter, the next call to sendto will fail with return code 10049. It doesn't matter if the other adapter is still connected, or was at the beginning, it will fail. The only thing that doesn't make it fail is deactivating wifi through the fancy win10 dialog through the taskbar, but that isn't really a surprise because that doesn't deactivate or remove the adapter itself.
I initially thought that this makes sense because when the nic is gone, how should the system route the packet. But: The fact that the packet can't reach its target has absolutely nothing to do with the address itsself being invalid (which is what the error means), so I suspect I am missing something here. I was looking for any information I could use to detect this case and distinguish it from simply trying to sendto INADDR_ANY, but I couldn't find anything. I started to log every bit of information which I suspected could have changed, but its all the same on a successfull sendto and the one that crashes (retrieved via getsockopt):

I need to pass some props to a third-party drawing library, but I need to pass only the initial value of the prop. I've made a wrapper component which captures the initial props in state, and then passes them to the third-party component.
This works, but since setZoom and setCenter aren't used, it feels like an anti-pattern:

How to write f2 using dependent pattern matching? (Code below compiles except definition of f2)
ANSWER
Answered 2022-Feb-24 at 12:25I'm not very familiar with fancy match expressions, but, in this very specific case, it seems it would be easier to just use Some _ in the match. You could prove, if you need this, a lemma stating that f1 No is always Some No_parse.
You could also instead define f2 to take an argument of type option (exp No), and delegate the issue to the function caller.
Of course, all this may be stating the obvious...

Answered 2022-Jan-11 at 17:06It looks like you have defined custom paths in your TypeScript config (usually tsconfig.json). The import plugin doesn't know about the correct location of the TypeScript config and hence cannot resolve those paths. What you need to do, is to specify the correct path to your TypeScript config via the project parameter in the resolver options:

Answered 2022-Jan-23 at 19:52The version of base is tied to the version of GHC. It looks like you're on GHC 9.2, which a lot of libraries still don't support yet. You can try passing --allow-newer to cabal, but I expect that to cause other problems. Downgrade to an older major version of GHC instead.

QUESTION
I have a database table of user interactions. I would like to create groups of users based on the time & place of interaction. That is, if users are interacting at roughly the same time (e.g., 2 minute window) in the same location, I would consider them a group. The groups do not need to be mutually exclusive, but they do need to be exhaustive. Every user interaction belongs in one or more groups.
I've done something similar to this in the past with python and a disjoint set. But now I am limited to a SQL solution.
Assume a toy data table like

QUESTION
I have a custom hook to help with async queries to an API. The hook works similar to a common useState statement in that you can set an initial value or leave it undefined. In the case of the built-in useState statement, the type of the state is no longer undefined when an initial value is specified (e.g. the type changes from (TType | undefined) to (TType)). In my custom hook, I have an optional parameter for the initial state, but I need to specify the type of the useState in the hook to be (TData | undefined) in case no initiaState is passed in.
But... when an initialState is passed in, I want the type to be only (TData) without the possibility of it being undefined. Otherwise, I need to put checks in place everywhere I use the hook, even when an initial value is set and it will never be undefined.
Is there a way to set the generic type of the useState inside my hook conditionally (i.e. when (initialState !== undefined) then the type is simply (TData), otherwise it is (TData | undefined)?

Answered 2021-Dec-18 at 10:05I originally came up with something that seemed overcomplicated so I asked Titian Cernicova-Dragomir to look it over. He was able to simplify it (as I suspected). It turns out the key was something I'd done quite late in the process of building my original: Using & {initialState?: undefined} in one of two overload signatures to add in undefined to the possible types that the data member of the returned object could have.
Here's the result, with explanatory comments. There's an assumption in there: That you want the setData function not to accept undefined even when there's no initialState (and so TData has undefined in it). But there are instructions for removing that if you want setData to accept TData (even when it includes undefined).
QUESTION
I have a NextJS project, using the NextJS router to route the user to a page based on a certain state variable.
I looked up how to do what I want using the NextJS router documents which has this example:
...ANSWER
Answered 2021-Nov-11 at 07:03Currently, this is a bug.
It seems that the useRouter methods changes useRouter itself. So every time you call one of these methods, useRouter is changing and that leads to this loop.
And the other problem with this is that Next.js is not memorizing useRouter, so it changes even if the value is the same.
Currently, the closest workaround I have found comes from a comment on this open issue https://github.com/vercel/next.js/issues/18127#issuecomment-950907739.
And what it does is that it "converts" useRouter into a useRef and exports the push method. So every time you use this method, this reference won't change if the value didn't change.
Workaround:
I quickly came up with this, which seems to have worked:
