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:
...ANSWER
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
May I have a question about my error during valgrind check?
I don't know how to fix this error below: at 0x4C2E2B1: __strcmp_sse42 (vg_replace_strmem.c:852)
...ANSWER
Answered 2021-Jun-15 at 15:03This occurs when the string doesn't a NULL terminated string. In this case, the value "-all" or argv[1] maybe doesn't a NULL terminated string, therefore the strlen will return an indeterminate value, because strcmp goes past the end of the strings and past the memory you allocated for them.
Try add \0 in the end of the string before the strcmp.
QUESTION
I am having trouble tracking down documentation on this, so hoping someone knows as I am not able to get application insights to capture telemetry on starttrackevent and stopstrackevent across pages. This is an asp.net mvc application, so SPA is not in play here.
I am worried I may be doing something incorrectly, however the likely case is it doesn't support it.
Flow:
- user hits site for the first time
- user does action that triggers startTrackEvent("eventName");
- user navigates to a new page
- user does action that triggers stopTrackEvent("eventName");
-- from the appInsights readme https://github.com/microsoft/ApplicationInsights-JS/blob/master/README.md
appInsights.startTrackEvent("event");
appInsights.stopTrackEvent("event", null, {customProp1: "some value"});
ANSWER
Answered 2021-Jun-15 at 22:35Not per documentation, but via testing, can confirm that when a new page loads, appInsights will not persist start/stoptrackevent.

QUESTION
I'm trying to use BS4 to parse through the HTML for an about page on a youtube channel so I can scrape the number of channel views. Below is the code to scrape the channel views (located in the 'yt-formatted-string') and also the whole right column of the page. Both lines of code return either an empty list and a "None" value for the findAll() and find() functions, respectively.
I read another thread saying I may be receiving an empty list or "None" value because the page is accessing an API to get the total channel views to count and the values aren't actually in the HTML I'm parsing.
I know I could access much of this info through the Youtube API, but I want to iterate this code over multiple channels that are not my own. Moreover, I want to understand how to use BS4 to its full extent so I can replicate this process on an Instagram page or Facebook page.
Should I be using a different library that isn't BS4? Is what I'm looking to accomplish even possible?
My CODE
...ANSWER
Answered 2021-Jun-15 at 20:43YouTube is loaded dynamically, therefore urlib won't support it.
However, the data is available in JSON format on the website. You can convert this data to a Python dictionary (dict) using the built-in json library.
This example is using the URL you have provided: https://www.youtube.com/c/Rozziofficial/about, you can change the channel name, it will work for all channels.
Here's an example using requests, you can use urlib instead:

QUESTION
I've been attempting to create a node class which mimics a node on a graph. Currently, storage of the predecessor and successor nodes are stored via a node pointer vector: std::vector previous. The vectors for the predecessor/successor nodes are private variables and are accessible via setters/getters.
Currently, I am dealing with updating the pointer values when adding a new node. My current method to update the predecessor/successor nodes is through this method (the method is the same for successor/previous nodes, just name changes):

The following code does everything I want: pulls email, saves attachments, extracts files EXCEPT save the original email to the folder fDest. I seem unable to see the solution.
This seems to be the problematic line as it won't save the email: "mi.SaveAs fDest2, olMSG"
...ANSWER
Answered 2021-Jun-15 at 19:38You must be sure there are no invalid characters in the filename. See What characters are forbidden in Windows and Linux directory names? for more information. So, I'd suggest using the Replace method available in VBA before passing anything to the SaveAs method.
Another point is that you need to specify unique file names to each email. Make sure the generated file name is unique for a folder.
QUESTION
I am relatively new in dealing with txt and json datasets. I have a dialogue dataset in a txt file and i want to convert it into a csv file with each new line converted into a column. and when the next dialog starts (next paragraph), it starts with a new row. so i get data in format of
...ANSWER
Answered 2021-Jun-15 at 19:08A CSV file is a list of strings separated by commas, with newlines (\n) separating the rows.
Due to this simplistic layout, it is often not suitable for containing strings that may contain commas within them, for instance dialogue.
That being said, with your input file, it is possible to use regex to replace any single newlines with a comma, which effectively does the "each new line converted into a column, each new paragraph a new row" requirement.
QUESTION
This could be just semantics and may be a stupid question, but I'm curious if the following would be considered overloading:
...ANSWER
Answered 2021-Jun-15 at 18:38When in doubt, JLS will help:
If two methods of a class (whether both declared in the same class, or both inherited by a class, or one declared and one inherited) have the same name but signatures that are not override-equivalent, then the method name is said to be overloaded.
So it's not "changing the parameters", it is about not override-equivalent. To find out what that is, you go to another chapter, that says:
Two method signatures m1 and m2 are override-equivalent iff either m1 is a subsignature of m2 or m2 is a subsignature of m1.
And the same chapter explains what subsignature is:
The signature of a method m1 is a subsignature of the signature of a method m2 if either:
m2 has the same signature as m1, or
the signature of m1 is the same as the erasure (§4.6) of the signature of m2.
How you interpret your above methods is an exercise left to you.
