QUESTION
I'm working on a C++ 98 project with platform toolset version v120 on VS 2013. I'm trying to implement Discord bot API in my project. I've tried several unofficial Discord libraries for C++, like Sleepy-Discord, DPP, and Discord.CPP. But it seems like none of them are compatible with my project's C++/platform toolset version. Unfortunately, I cannot update my project as it's too big. I want to know if there's any solution for this.
What I'm expecting:
- A Discord lib for CPP compatible with my project's PTV v120.
- Or a way to downgrade one of the Discord libraries to make it compatible with my project.
- Or a way to interact with the Discord API through my project.
- Any other way.
Thank you.
...ANSWER
Answered 2022-Mar-21 at 03:41As stated on the Discord Developer Portal, their API can be accessed entirely through web requests. You don't need any additional libraries, except if you want to use a prebuilt REST or WebSocket library for easier use, which - if available to you - i would highly recommend.
QUESTION
I have a table which I would like to get the latest entry for each group using Kusto Query Language. Here's the table:
DocumentStatusLogs
ID DocumentID Status DateCreated 2 1 S1 7/29/2011 3 1 S2 7/30/2011 6 1 S1 8/02/2011 1 2 S1 7/28/2011 4 2 S2 7/30/2011 5 2 S3 8/01/2011 6 3 S1 8/02/2011The table would be grouped by DocumentID and sorted by DateCreated in descending order. For each DocumentID, I want to get the latest status.
My preferred output:
DocumentID Status DateCreated 1 S1 8/02/2011 2 S3 8/01/2011 3 S1 8/02/2011Is there any way to get only the top from each group using KQL?

...ANSWER
Answered 2022-Mar-09 at 09:29- Both OMPR and GLPK are slow for large models.
- You are duplicating
sum_over(x[i,j], j = 1:ncol(LCMat)). That leads to more nonzero elements than needed. I usually try to prevent that (even at the expense of more variables).
QUESTION
I am trying to read a file which in default is supposed to have 7 columns but probably there might be some commas within some strings which is causing other rows to have more than 7 columns.
Regardless of which info that is in other columns my only goal is to read the first 7 columns. However, fread is not reading the whole file even after adding the argument select = 1:7

QUESTION
I am making a program, and one feature I would like to implement is a error-checking type of thing, where if the C++ program searches through the program and doesn't find a match, it will return the closest matching string.
I currently have a setup like so:
...ANSWER
Answered 2021-Dec-06 at 03:31Part 1 (see Part 2 below)
As suggested by @BasileStarynkevitch, you can implement Levenstein distance, which measures edit distance (number of insertions, deletions, substitutions) between two strings, or in other words how similar two strings are, the closer value of Levenstein distance to 0 the more strings are similar.
Just now I implemented from scratch this distance computation in C++. And showed an example of using this distance function to find closest string among given strings to the query string.
Function Levenstein() is implemented according to WikiPedia (link above), and is not optimized only to make it easy to read and understand, for educational purposes. In production code to make it much faster use Memoization technique (cache results of same function calls), because as you can see my implementation will be quite slow for larger strings, for same two strings it will do a lot of redundant same function calls. Another way to speed up computation is to use Dynamic programming approach to cache and reuse previous results inside array.

Answered 2021-Jul-29 at 12:27You are seeing different performance because you have changed the meaning of the condition. The new condition just happens to be easier for the DBMS to optimise.
In SQL, as in most programming languages, the AND operator has higher precedence than the OR operator. That means that your original code:

QUESTION
In my project, I need to get organization data's from api firstly, then ı need to get another specific data's from another api with sending as a parameter organizationEIC property of my organization data which ı get in first request. I can get the organization datas successfully and set them to items state successfully. But when ı came to the second API request which made in getPlants() method, my program and my RAM fail and ı get net::ERR_INSUFFICIENT_RESOURCES error for each request. I just put the incoming data to the datas array in order not to setState every time and to prevent the component from rendering again, but the program still crashes. I got some solutions with using hooks but I'm beginner in react and ı don't have any knowledge about hooks and want to solve this issue with basic react to develop myself better.
...ANSWER
Answered 2021-May-09 at 13:07(1) This probably happened because you are calling .getPlants() on every render. You should probably call getPlants inside componentDidMount instead.
(2) You may use promise.all to speed up your fetch.
