QUESTION
I'm new to React and I'm doing a learning project where I build an extremely simple Mad Libs game. I'm struggling and not sure how to go about doing it.
I built a skeleton, but I'm not sure how to pass props from
and also not sure how to deal with useState
.
I'd appreciate any help. This is what I have so far:

QUESTION
Sorry for the wording in the question. Probably my biggest issue with this is not knowing how to phrase it correctly, as I've not been able to gleam a single hint of an answer from google.
Using api routes in Next.js I want to serve a data.json
file. This works no problem, however I also want to be able to edit this file afterwards and for the api to reflect the updated content. As it stands after building and running if I edit the file the api still returns the old one, hell I can even delete it. I assume this is because Next.js makes a copy of the file at build time, and puts it somewhere in the .next directory(?), haven't been able to find it there though.
Below is a boiled down version of what I'm doing:
...ANSWER
Answered 2021-Jun-07 at 01:21Using require
to include a file in any Node app will definitely tie the json file to the apps run time or build time.
The feature you describe sounds like static file serving but next caches those files as well.
Try reading the file in the API instead

Answered 2021-May-28 at 11:04It does appear as if Chrome has trouble applying a clipping path to images. It seems to be a little worse when the image is moving - as in your case.
However there is an easy fix. Use a instead.
Or I expect switching the gleam from an image to an SVG object with a linearGradient would also work just fine.
Example using a mask instead of a clip path
(Note that I've trimmed the SVG down to just show the important bits)
QUESTION
Hello all,
i am having problems getting the file preview (the one shown on the right side in the Windows Explorer window) for a certain file.
So far fetching the file preview works fine, but it takes a long time (between 0.5 and 2 seconds). Thus i do not want it to be executed in the main thread (as this would interrupt the program gui).
I tried to execute the file preview extraction in a worker thread, but this yields a SIGSEGV
.
The call stack is also not really useful, it only shows that the exception is raised in ShellObjHelper
in Line 141 (see source code below).

Answered 2021-Apr-13 at 07:07Thanks to the comment from @IInspectable, that's the hint i needed.
Solution:
Add CoInitialize
before calling GetExtractImageItfPtr
and add CoUninitialize
after receiving the file preview, but still within the worker thread.
Ensure that CoUninitialize
is called even if exceptions occur by using try
and finally`.

I know this sounds really strange, but I don't know how to even ask this properly. I've been trying to P/Invoke into NVidia's NVML library with limited success: I've managed to call a few of the APIs exported by that library
Now I am trying to call nvmlDeviceGetHandleByIndex_v2
but I've been stuck for a long while on this one. It takes in a nvmlDevice_t
pointer, but I've found nothing on what nvmlDevice_t
actually is beyond this header definition:
ANSWER
Answered 2021-Feb-19 at 00:03If you look at the source, that is just an internal pointer used by the SDK. The value it points to has no meaning to you. You use it to identify a device you are working with.
Think Handle
or HWND
in Windows. You call something like FindWindow()
, it returns what seems to be a random value back to you. You don't care what that value holds, you just use that value to identify that window when you call GetWindowText()
or any other windowing methods.
So, you are on the right track with using ref int
, but what you want is a pointer. So you should use out IntPtr
to get the value.
QUESTION
I'm trying to follow a tutorial online for a project using django channels. Trying to install the requirements.txt resulted in an error when trying to install Twisted==16.4.0, so I tried just pip install Twisted to see if the latest version results in the same error.
And it did. I'm not sure exactly what the problem is, I ran into a very similar problem trying to install greenlet for a flask-socketio project, which made me give up and try django channels. This is quite demotivating.
I did this in a virtual environment, I think there might be something wrong with my visual studio C++ stuff? I really can't gleam anything from this error, seeing as to how it's so long and I'm really new to this.

I'm creating a cross-platform GUI App with fltk-rs. Depending on which platform I'm targeting (OSX or Windows), I'd like to use a different struct for my menu bar. If I'm targeting OSX, for my menu bar I'd like to use fltk::menu::SysMenuBar
and for Windows, I'd like to use fltk::menu::MenuBar
.
I don't want to keep to separate versions of my code, one for Windows, and one for OSX, just so I can use different a different Struct for my menu.
What are some approaches to changing which struct is used based on the build target without creating different codebases?

QUESTION
Okay, I've been reading articles and the paper about Kademlia recently to implement a simple p2p program that uses kademlia dht algorithm. And those papers are saying, those 160-bit key in a Kademlia Node is used to identify both nodes (Node ID) and the data (which are stored in a form of tuple).
I'm quite confused on that 'both' part.
As far as my understanding goes, each node in a Kademlia binary tree uniquely represents a client(IP, port) who each holds a list of files.
Here is the general flow on my understanding.
- Client (.exe) gets booted
- Creates a node component
- Newly created node joins the network (bootstrapping)
- Sends find_node(filehash) to k-closest nodes
- Let's say hash is generated by hashing file binary named file1.txt
- Received nodes each finds the queried filehash in its different hash table
- Say, a hash map that has a list of files(File Hash, file location)
- Step 4,5 repeated until the node is found (meanwhile all associated nodes are updating the buckets)
Does this flow look all right?
Additionally, bootstrapping method of Kademlia too confuses me. When the node gets created (user executes the program), It seems like it uses bootstrapping node to fill up the buckets. But then what's bootstrapping node? Is it another process that's always running? What if the bootstrapping node gets turned off?
Can someone help me better understand the concept?
Thanks for the help in advance.
...ANSWER
Answered 2020-Jan-09 at 19:56Does this flow look all right?
It seems roughly correct, but your wording is not very precise.
Each node has a routing table by which it organizes the neighbors it knows about and another table in which it organizes the data it is asked to store by others. Nodes have a quasi-random ID that determines their position in the routing keyspace. The hashes of keys for stored data don't precisely match any particular node ID, so the data is stored on the nodes whose ID is closest to the hash, as determined by the distance metric. That's how node IDs and key hashes are used for both.
When you perform a lookup for data (i.e. find_value
) you ask the remote nodes for the k-closest neighbor set they have in their routing table, which will allow you to home in on the k-closest set for a particular target key. The same query also asks the remote node to return any data they have matching that target ID.
When you perform a find_node
on the other hand you're only asking them for the closest neighbors but not for data. This is primarily used for routing table maintenance where you're not looking for any data.
Those are the abstract operations, if needed an actual implementation could separate the lookup from the data retrieval, i.e. first perform a find_node
and then use the result set to perform one or more separate get
operations that don't involve additional neighbor lookups (similar to the store
operation).
Since kademlia is UDP-based you can't really serve arbitrary files because those could easily exceed reasonable UDP packet sizes. So in practice kademlia usually just serves as a hash table for small binary values (e.g. contact information, public keys and such). Bulk operations are either performed by other protocols bootstrapped off those values or by additional operations beyond those mentioned in the kademlia paper.
What the paper describes is only the basic functionality for a routing algorithm and most basic key value storage. It is a spherical cow in a vacuum. Actual implementations usually need additional features or work around security and reliability problems faced on the public internet.
But then what's bootstrapping node? Is it another process that's always running? What if the bootstrapping node gets turned off?
That's covered in this question (by example of the bittorrent DHT)
