QUESTION
TL;DR: Why do I name go projects with a website in the path, and where do I initialize git within that path? ELI5, please.
I'm having a hard time understanding the fundamental purpose and use of the file/folder/repo structure and convention of projects/apps in the go language. I've seen a few posts, but they don't answer my overarching question of use/function and I just don't get it. Need ELI5 I guess.
Why are so many project's paths written as:

Answered 2021-Jun-16 at 02:46Why do I name projects with a website in the path?
If your package has the exact same import path as someone else's package, then someone will have a hard time trying to use both packages in the same project because the import paths are not unique. So long as everyone uses a string equal to a URL that they effectively "own", such as your GitHub account (or actually own, such as your own domain), then these name collisions will not occur (excepting the fact that ownership of URLs may change over time).
It also makes it easier to go get
your project, since the host location is part of the import string. Every source file that uses the package also tells you where to get it from. That is a nice property to have.
Where do I initialize git?
Your project should have some root folder that contains everything in the project, and nothing outside of the project. Initialize git in this directory. It's also common to initialize your Go module here, if it's a Go project.
You may be restricted on where to put the git root by where you're trying to host the code. For example, if hosting on GitHub, all of the code you push has to go inside a repository. This means that you can put your git root in a higher directory that contains all your repositories, but there's no way (that I know of) to actually push this to the remote. Remember that your local file system is not the same as the remote host's. You may have a local folder called github.com/myname/
, but that doesn't mean that the remote end supports writing files to such a location.
QUESTION
I have a python code I know where is it used but want to know its meaning so that I can use it for my bigger python projects This is my python code
...ANSWER
Answered 2021-Jun-16 at 01:27I don't know if I understood your question, but this is what the code is doing:
var_list is a list with two elements [100, 2025]
.
slice1 and slice2 are being defined as (var_list + [None]*2)[:2]
. This expression adds the var_list to a new list of 2 None objects ([None] * 2 == [None, None]
). The result of this expression ((var_list + [None] *2)
) is the addition of these 2 lists, which is: [100, 2025, None, None]
Then the last part ([:2]
) is just slicing the first 2 elements of this resulting list and assigning it to the variables. And since, in this case, the first 2 items are the var_list itself, it will assign the first element to slice1 and the second to slice2.
QUESTION
I was following along with this tutorial on creating a concurrent counter struct for a usize
value: ConcurrentCounter
. As I understand it, this wrapper struct allows us to mutate our usize
value, with more concise syntax, for example:my_counter.increment(1)
vs. my_counter.lock().unwrap().increment(1)
.
Now in this tutorial our value is of type usize
, but what if we wanted to use a f32
, i32
, or u32
value instead?
I thought that I could do this with generic type arguments:
...ANSWER
Answered 2021-Jun-15 at 23:55I haven't come across such a ConcurrentCounter
library, but crates.io is huge, maybe you find something. However, if you are mostly concerned with primitives such as i32
, there is a better alternative call: Atomics, definitely worth checking out.
Nevertheless, your approach of generalizing the ConcurrentCounter
is going in a good direction. In the context of operation overloading, std::ops
is worth a look. Specifically, you need Add
, Sub
, and Mul
, respectively. Also, you need a Copy
bound (alternatively, a Clone
would also do). So you were pretty close:

This way the 2 def
s that depends on each other will be available at the same time.
IntelliJ worksheets do not like such definitions as they are "evaluated" one by one. You cannot define 2 depending on one the other at the top-level, they need to be encapsulated.
QUESTION
I have two functions one thats triggered on a mouseenter event and the other on mouseleave. Both of these functions are repeated three times.
On mouseenter the classlist "active" is addded 5x and the text content is changed.
On mouseleave the classlist active is removed 5x and the text content is set to an empty string, and the original image is displayed again.
When the mouseenter event listener is triggered, Depending on which image is being hovered (3 images).
the text content property that gets added various between the three "Photosnap" "Dine" "Nike".
As-well as the background color that gets triggered various between "red" "blue" "pink".
Hover state shown as red left image and normal state shown as right image
-The image shown here is one of three. It is displayed with a red background and the text content of "photosnap".
-The other with a blue background and the text content of "Dine".
-The third and final with a pink background and the text content of "Nike".
I hope this paints a clear picture i am having a hard time making this a code snippet.
I am trying to refactor this javascript so its not so repetitive. I'm new to javascript and having a hard time getting this to work as something other than what i currently have. I'm not clear on how to make a function that i can call inside of other functions to cut down on the repeated code. Or possibly use the "this" keyword ?

Answered 2021-Feb-16 at 13:11Upgrade your dagger-hilt dependencies to the same version.

Your app level gradle file
implementation "com.google.dagger:hilt-android:2.31.2-alpha"

ANSWER
Answered 2021-Jun-15 at 09:31This is extreme weird behaviour, and I dont really think github and slack are linked together somehow that magically remove APP as soon as its Token got exposed.
They are, though: https://docs.github.com/en/code-security/secret-security/about-secret-scanning
Secret scanning is a mechanism to do just that, detect accidentally leaked secrets in GitHub and report them to the affected service. There are 40+ partners already participating in this, including Slack.
GitHub scans repositories for known types of secrets, to prevent fraudulent use of secrets that were committed accidentally.
Secret scanning is automatically enabled on public repositories. When you push to a public repository, GitHub scans the content of the commits for secrets. If you switch a private repository to public, GitHub scans the entire repository for secrets.
Probably intentionally publishing a live token to a public GitHub repo is a not the right approach, I'd recommend using a private repo instead.
