In the Map, set the value not to the cumulative total time for the employee so far, but to a whole employee object that contains the total time inside it. Spread the first object found so as not to mutate the input.

Understanding splitting list item to variable python code

ANSWER

Answered 2021-Jun-16 at 01:27

I 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.

How to make an axios get request on page load, then render a am4chart with that data?

Asked 2021-Jun-15 at 22:40

I have the wackiest bug. Like....the wackiest! If any of ya'll want to put eyes on this, awesomesauce! I really appriciate it! I am creating a survey with REACT, Redux, SQL, HML, Material-ui, and CSS.

I've created a graph of information with am4charts using data from a database. Everything is working and will show up on the page......but not on page load. What I am seeing in my console is that the page will load, it fires off my get request but doesn't return with the data fast enough (I think). By the time that the get request loads, my graph has populated with no data.

Here is the code that I have for the page that I am rendering. What is really odd is that, once my code has run, I can cut a line of code (I've been using a console log). And then the graph will render and load.

QUESTION

Good way to switch between 2 versions of the same dependency in package.json?

Asked 2021-Jun-15 at 21:43

Turns out you can't have comments in JSON files, and it's a bit awkward to have people refer to some documentation telling them what line to copy/paste in and where in order to achieve this.

I think I can make a python script to copy/paste in one of two package.json files depending on what flags they pass in, but that feels overcomplicated.

I think I can include both dependencies (under different names) but that would create a requirement for both to be available, which is not good either.

Looking for ideas/thoughts on a good way to accomplish this. I have a release and dev version of the same dependency and I often need to swap between the two. Would like to improve the workflow beyond just having a notepad on the side with the two lines pasted in it...

QUESTION

How to use select() to set a timer for sockets?

Asked 2021-Jun-15 at 21:17

I'm currently using Winsock2 to be able to test a connection to multiple local telnet servers, but if the server connection fails, the default Winsock client takes forever to timeout.

I've seen from other posts that select() can set a timeout for the connection part, and that setsockopt() with timeval can timeout the receiving portion of the code, but I have no idea how to implement either. Pieces of code that I've copy/pasted from other answers always seem to fail for me.

How would I use both of these functions in the default client code? Or, if it isn't possible to use those functions in the default client code, can someone give me some pointers on how to use those functions correctly?

...

ANSWER

Answered 2021-Jun-15 at 21:17

select() can set a timeout for the connection part.

Yes, but only if you put the socket into non-blocking mode before calling connect(), so that connect() exits immediately and then the code can use select() to wait for the socket to report when the connect operation has finished. But the code shown is not doing that.

setsockopt() with timeval can timeout the receiving portion of the code

Yes, though select() can also be used to timeout a read operation, as well. Simply call select() first, and then call recv() only if select() reports that the socket is readable (has pending data to read).

QUESTION

How would you set up a database to handle comments for a blogging site?

Asked 2021-Jun-15 at 19:59

I'm a student learning about database design and currently learning about the relationships of - one-to-one, one-to-many, many-to-many. I understand the concept well enough, but feel like I'm lacking experience/information on how it would be implemented in a real production scenario.

My question is this

If I have a blog website with a Blog Post as an entity and comments for each blog post, how would you handle the comments in the database?`

Would you use a one-to-many relationship and just store all the comments in a single table. Then link those comments to each blog post and user who created it?

What if each comment had a sub-comment? Would you create a separate table for sub-comments and link it to a single comment? Would that cause too much overhead and confusion within the DB itself?

I get the concepts and all, but don't understand best practices for handling what seems like basic stuff.

Thanks in advance!

...

ANSWER

Answered 2021-Jun-15 at 16:06

The simplest solution is to stick with a one-to-many relationship. Use one table and store one comment per row, with references to the post and the comment author, and a timestamp so you can sort the comments chronologically.

You seem uncertain about whether you need a "threaded comment" hierarchy. This is more complex, so if you don't need it, don't bother.

If you do need to show comment threads, then you should learn about running recursive queries in MySQL 8.0: https://dev.mysql.com/doc/refman/8.0/en/with.html#common-table-expressions-recursive

You still only need one table. Don't create a second table for sub-comments. Just store comments like in your one-to-many example, but each comment may link to its "parent" comment when it is a reply.

Another solution that many sites use is to skip implementing their own comment system, and just embed a comment service like Disqus. That's likely to be much more reliable and safe than yours. But if you're doing this as a learning exercise, that's worthwhile too.

Save Outlook Mailitem to local folder

Asked 2021-Jun-15 at 19:38

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 19:38

You 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.
