QUESTION
I have a sidebar with anchor links that point to a specific content part when I click on them.
The problem appears when I'm scrolling the content, the link in the sidebar gets highlighted when the section title barely appears at the bottom.
How can I make the link change when the title of chapter content reaches the top of sidebar?
Here's what I tried so far but isn't working exactly as I want.
...ANSWER
Answered 2020-Oct-05 at 08:04The reason this is happening is because section.offsetTop is returning the position of the section relative to the offset parent. In this case the parent is the div that contains the sections
To fix the problem, we just need to adjust the value for the top of each section to take into account the distance of the parent from the top. We do this as follows:
1. Add an id to the parent container to make it easier to select, e.g.
QUESTION
I don't know how Return to Menu (for if you are in info) doesn't find startmenu.html though I know that it should. After all, all of the other Return to Menu's work and I am using the same exact line of code for all of them.
info.html:

Answered 2020-Sep-25 at 22:39The nature of the problem is evident in your off-site example, but not in the code you're showing. So it seems you're looking in the wrong place.
Your other pages can use this link because they're all in the same folder as the "menu" page:
QUESTION
I have a sidebar with links that are changing when I'm scrolling a long content. The problem is that the change is happening too early when the chapter title is barely at the bottom of the page.
How can I write if(fromTop >= 100) differently, to get sticky when it reaches the row startContent?
Thanks for any suggestions!
...ANSWER
Answered 2020-Oct-04 at 20:42I added an identifier to the container of the chapters, so the sidebar gets sticky only when the top of such container reaches the top of the window. Is this what you intended?

QUESTION
I implemented the lazy pirate pattern for my client module, which works great for retrying the requests. But here's the problem.
- REQ Client sends message to REP server. [OK]
- REP server interprets the message. [OK]
- REP server executes some action, and prepares the response. [OK]
- REP server sends back the response. [OK]
- REQ Clients polls message but doesn't receive any until it timeout. [NOT OK]
- REQ Client restarts the socket, and retries to send the request again. [NOT OK]
- REP Server executes the action again. [THE PROBLEM]
- This time REQ Client successfully receives the response. [OK]
That's the problem, I'm executing the action twice which was intended to be only executed once. I think this is the best way I could explain it.
In certain occasions client can send simultaneously send request to server as I have a coroutine running on a thread, separated from the main thread both of which has functionality that sends request to server. Could this be the cause of it?
I also have multiple of these clients connected to the server, could this be the problem?
Thank you!
...ANSWER
Answered 2020-Aug-09 at 19:56Q1 : "Could this ... coroutine based co-existence ... be the cause of it?"
Yes,
mostly if coroutines use the same instance of the REQ-archetype.
Q2 : "... could this ... multiple of these clients connected to the server ... be the problem?"
No,
given each client operates on it's own instance of a REQ-archetype, connected towards the REP-(server)-side, there ought be no reason to imminent blocks ( for details, read more about the REQ/REP principal certainty to fall into an un-salvagable mutual dead-lock, where the only thing you cannot know is, when it will happen, but we all may be sure, it will happen )
If an atomic, singleton-alike unique executions are needed ( and if server implementation permits that ), one may log each REQ's task-{UUID}, to prevent double-shots onto the same task-target.
There is hardly to tell more, without the actual MCVE / MWE-representation of the problem ( the .poll-ing loop logic / timeout / remedy-strategies )

QUESTION
I imagine the solution to this can be found i similar topics, however, it seems a little bit different from problems I have seen.
The redirect, in add_post view, should send me to the Post class, where I have a get_absolute_url.
But it happens that I get the following error message: get_absolute_url() missing 1 required positional argument: 'self'
I literally copied the coded form the "Django Projects Cookbook" in case you wanna check it out and try the code yourself.
Thank you.
...ANSWER
Answered 2020-Jul-22 at 22:24You use the Post class, not its object to redirect. You thus need to use post in:

I want to run this example about 1D Gaussian Mixture Example: http://www.astroml.org/book_figures/chapter4/fig_GMM_1D.html But I have this error all the time:
...ANSWER
Answered 2019-Apr-22 at 19:10The newer versions of scikit-learn don't have that module. From looking at the versions it was deprecated in v 0.18 and removed in v 0.20. Here is the link to the OLD 0.18 module, which is the first instance i could find that shows a deprecation warning. https://scikit-learn.org/0.18/modules/generated/sklearn.mixture.GMM.html#sklearn.mixture.GMM if you want you can install an older version
pip install -Iv scikit-learn==0.15, or if you want to use the newer version, adapt the parameters of your GaussianMixture to reflect their new names (e.g. in GaussianMixture, max_iter is the number of iterations, instead of n_iter).
QUESTION
I'd like to install some application data in C:\ProgramData folder using nsis installer. I'd like to avoid hardcoding it, because it may not be on C: drive.
The documentation https://nsis.sourceforge.io/Docs/Chapter4.html doesn't have any constant that defines ProgramData. What is the nsis way of installing in ProgramData folder?
ANSWER
Answered 2020-Mar-23 at 23:45Microsoft moved and renamed some of the special folders in Vista. %ProgramData% is CSIDL_COMMON_APPDATA and you can get that path in NSIS:
