I am having trouble understanding how constant constructors and the constructor initializer list in dart.

I have this small code:

I'm quite new to Gtk3 and just learned how to load an image, but I do not want it to be hardcoded in, so I can share my app and it works for everyone without changing anything.

TL;DR: Is it right to assume, given enum NAME {...};, that enum NAME n is the same as int n during execution? Can n be operated on as if it were a signed int, even though it is declared as enum NAME? The reason: I really want to use enum types for return flags, as a type 'closed' with respect to bit-operations.

For example: Let typedef enum FLAGS { F1 = 0x00000001, F2 = 0x00000002, F3 = 0x00000004 } FLAGS ; Then, FLAGS f = F1 | F2; assigns 3 to f, throwing no related errors or warnings. This and numerous other compiler-permitted usage scenarios, such as f++, makes me think I could legit treat f as if it were a signed int. Compiler used: MSVC'19, 16.9.1, with setting "C17 (2018) Standard (/std:c17)";

I searched the standard (the sketch here) and looked at other related questions, to find no mention of what suspect (and wished) to be a "silent promotion" of enum NAME x to signed int x, even though the identifiers have that type. This leads me to believe that the way enum behaves when assigned a value that isn't a member, is implementation dependent. I'm asking, in part, in order to confirm or deny this claim.

I'm trying to clean up podcast descriptions in PHP to get rid of bad characters like invisibles, emojis, random bytes, etc, to write to MySQL. The problem is podcast descriptions are in all languages and contain legit text I need to keep in every imaginable character set, probably including some unimaginable ones. I can't see a way to create either a character whitelist or a character blacklist. Any suggestions?

Here is my useEffect with a simple clean-up function () => { inbox?.destroy(); }, but it raises a warning when I let the clean-up function there. Why is that, isn't the clean-up function a legit syntax? How to fix it (of course without removing the clean-up function)?

I have a rather simple question on using react-table from React.js.

I cannot find any samples nor documents regarding useMemo for a local json, pretty much all of the tutorials are based on asyn api.

The objective is to create a table as such: https://codesandbox.io/s/github/tannerlinsley/react-table/tree/master/examples/pagination?file=/src/App.js

The only difference between the tutorial and mine, is the makeData file would be an actual json file with legit data.

This is what I tried:

I'm building a React application that uses API Gateway and Lambda on the back-end. I'm going through the process of integrating Cognito authentication. I've completed the following:

Typical legitimate email "header from" fields look like:

From: DHL

From: DHL

while non legitimate email "header from" fields look like:

From: DHL

I would like to write a regex that matches in case of non legitimate email "header from", that is, if DHL appears after the "From:", then what is inside the <> must end with dhl.com

I came with the following regex using negative lookahead (not sure it's 100% exact but it seems to work):

^From: DHL <.*@(?!.*dhl\.com>$)

Now the problem is that my regex engine does NOT support negative lookahead and I'm trying to replace it by an equivalent non capturing group like:

(?:[^d]|d[^h]|dh[^l]|dhl[^\.]|dhl\.[^c]|dhl\.c[^o]|dhl\.co[[^m])

without success so far. Any idea ?

And if there is a solution, I would like to support case mixing as well (like DhL.COm).

I am looking for a Postfix solution, ideally one which does not require PCRE.

I've got a code snippet that is supposed to download an S3 file using file streaming:
