haskell-language-server is giving me some hints on how to reduce code length, but while I'm learning I would like to disable this hints temporary so I can work on examples from books without the annoying hints polluting the editor. I still want error report, just disable the hints

QUESTION
I'm learning C++ and have come to a bit of a halt. I'm trying to iterate over a vector with a range-based for loop and update a property on each of the objects that belong to it. The loop is inside of an update function. The first time it fires, it works fine; I can see the property gets updated on each member of the vector. However, the next time the for loop is initiated, it's still updating the original data, as if the previous run did not actually update the source values. Is my range declaration configured correctly? Pointers are still a bit of a mystery to me. In general I'd be very thankful for any help!
...ANSWER
Answered 2021-Jun-15 at 23:19Vector3 position = point.position; makes a copy of point.position. The following code then updates this copy, which in turn is thrown away when it goes out of scope at the end of the if statement.
The solution is simple enough - use a reference instead: Vector3 &position = point.position;. The rest of the code can be left as-is.
QUESTION
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 16:06The 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.
QUESTION
I'm currently learning HTML, CSS, and JavaScipt. I'm trying to make a basic project, but I'm having problems with adding a new image on the new card. When I click on the 'add item' button, I create a new card with image. However, when I add another card for the second time, my image from the first card that I created will disappear. Can someone help me on how to fix this solution. Thank you.
...ANSWER
Answered 2021-Jun-15 at 19:05Rather than using two different function, one for adding card image and one for card content, try combining both of them.. here use the code for your reference.
QUESTION
I am a beginner learning from a tutorial on how to change the colour of a selected area of a picture with a range of colour options.
I can figure out how to change one area, but unsure how to implement the other areas.
What I want to achieve is to click on the selected area, it highlights the border (CSS), then change the colour by using the colour options.
What is the best way to implement this? I'm I correct in thinking maybe a switch statement with onclick to select the specific area of the picture?
...ANSWER
Answered 2021-Jun-15 at 11:48You could try having a "select" function run when you click on one of the areas. This function would "highlight" the area (border-color), and save the id of the area in a variable.
Then when you click on the color swatches another function would run that will take the value previously saved id and select the HTML element based on that.
QUESTION
Hey just doing some exercises in c, one is saying to replace tabs in the input string with any other characters , i restrict myself to only using getchar(), no gets() fgets() etc..., as my learning book didn't catch it yet, so i tried to not break the flow, the code below just printf() the same line it receives, can you please examine why ?

Answered 2021-Jun-15 at 16:33c, which is used inc != '\n', is not initialized at first. Its initial value is indeterminate and using is value without initializng invokes undefined behavior.- You are checking
line[i] != '\0', but you never assigned'\0'tolineunless'\0'is read from the stream. - You should initialize
ibefore the second loop and updateiduring the second loop. - Return values of
getchar()should be assigned tointto distinguish betweenEOFand an valid character. - You should perform index check not to cause buffer overrun.

I am using Visual Studio code for learning python, but I am unable to use the input function (in python). All other functions work properly. I am using python 3.9.2 and I have also installed the python extension in my VS Code. Here is an image of my code.
