Ok, but yours is an unnecessarily difficult approach. At each step of the merge process, you want half of your threads to wait for the other half to finish, and the most natural way for one thread to wait for another to finish is to use pthread_join(). If you wanted all of your threads to continue with more work after synchronizing then that would be different, but in this case, those that are not responsible for any more merges have nothing at all left to do.
This is what I've tried:

dissolve()as you describe, have not bothered with fact some of the attributes cannot be summed (long and lat) - simpler to see through visualisation, so have provided plots as each stage
- updated to use pandas

QUESTION
I want to separate a character string using the special characters in that string as cutting lines. After each division the next group of strings should be copied in the next column. The picture below shows how it should work.
My first approach doesn't work and maybe it's too complicated. Is there a simple solution to this task?

In MS Access I have a table with a Short Text field named txtPMTaskDesc in which some records contains numbers, and if they do, at different positions in the string. I would like to recover these numbers from the text string if possible for sorting purposes. There are over 26000 records in the table, so I would rather handle it in a query over using VBA loops etc.
While the end goal is to recover the whole number, I was going to start with just identifying the position of the first numerical value in the string. I have tried a few things to no avail like:
...ANSWER
Answered 2021-Jun-15 at 07:02If data is truly representative and number always preceded by "- No ", then expression in query can be like:
Val(Mid(txtPMTaskDesc, InStr(txtPMTaskDesc, "- No ") + 5))
If there is no match, a 0 will return, however, if field is null, the expression will error.
If string does not have consistent pattern (numbers always in same position or preceded by some distinct character combination that can be used to locate position), don't think can get what you want without VBA. Either loop through string or explore Regular Expressions aka RegEx. Set reference to Microsoft VBScript Regular Expressions x.x library.

QUESTION
I'm a newbie in Python and recently tried my luck setting up a bot (as you do...) made by Mark Powers called Telegram Arcade
As it was evident, it was built with python-telegram-bot framework. Even though it looked simple to set it up (with included instructions) I can't get it to work.
Even after I updated some of the code to be in line with the changes to the framework, now i get an error that is displayed along with the user that is interacting with the bot: function error at 0x7fcfa257f790 .
The code as of right now is as follows:
...ANSWER
Answered 2021-Jun-13 at 06:56python-telegram-bot changed how callbacks work in v12, which was released two years ago. The repo you're using seems to still work with the old callbacks. I recommend to first try & get it to work with ptb version 11.1. or 12.0 without passing use_context=True (in v12 this still defaults to False for backwards compatibility). If that works fine and you want to upgrade to newer python-telegram-bot versions, I highly recommend reading the transition guides for v12 and v13.

QUESTION
I am currently working on a labview project and have found myself stuck on how to make a while loop exit when I press the abort (stop) button. For a simple while loop I understand how to do this - but the problem is that this while loop is nested inside of an event structure and I'm guessing that the button cannot be pressed while the loop is executing. Attached here is a picture of part of my code (that contains this specific event case which is causing me problems): To spend a little more time explaining what the problem is - I think the code is doing what I want it to do (namely output a set of commands in a repeated cycle with a wait timer) but I cannot stop the code mid cycle (pressing the abort button with my mouse does nothing - as in the button doesn't show it being pressed and the indicator shows no change, I also can't use any other functionality of my program during the cycle which I'm assuming is related). And I do not want to stop the labview program from running entirely - just the code inside the while loop pictured above. This is what the front panel is configured too for completeness:
Essentially what I want to happen is the while loop to execute when I press DWG and in the middle of the cycle be able to abort it. Sorry if my code seems a little messy. Additionally, I've tried the same code with a for loop originally (via a conditional terminal so it could stop early) and that didn't work either. Thanks for any help I appreciate it!
...ANSWER
Answered 2021-Jun-13 at 05:14Your problem is that inside the event structure, by default the UI is frozen so no UI actions (keyboard/mouse/etc) are processed until you exit that frame.
Option 1. You can right click the Event Structure and select "Edit events handled by this case" dialog and then uncheck the "Lock panel" checkbox -- that will allow the UI to be live while you are in that frame. I do not recommend this solution generally unless you have an extremely simple user interface because it leads to the user being able to change controls without the events behind those controls being processed (not a good UI experience for users). But if the UI is simple enough, that works.
Option 2. You can create a user event that is the code you want inside your While Loop. When the Deg Wait Go button is pressed, use the "Generate User Event" node to trigger that event. Do the same thing in the user event case so that the event re-triggers itself if and only if the Abort button has not been pressed.
Option 3. Create a separate loop OUTSIDE your UI loop that does your processing with some sort of command queue running between the UI loop and that other loop. The other loop moves into various states at the request of the UI loop... it's the one that does nothing until it receives a "go" message and then keeps looping until it receives a "stop" message. You can Google "queued message handler" for extensive details of this solution. This is the most common solution for complex UI requirements, especially useful for separating concerns of the UI code from the execution code.
QUESTION
I have a list of integers. Now I want to sort from the middle. By this I mean:
- starts from the number in the middle if the length of the list is an odd number;
- starts from the larger of the two numbers in the middle if the length of the list is an even number;
- alternatingly take the numbers on the left and right (or right and left, depending on their magnitudes). Always first take the larger of the two.
I managed to write the following code, but only works for odd-size lists. It will not be hard to write an even version for this, but I feel like there has to be more general and "Pythonic" way to code this. I'm actually surprised that this trivial question has never been asked before.

QUESTION
I'm implementing Binary search. But I don't want to pass the size of an array as an argument in the binarySearch function. I'm trying to find array size in function. I use sizeof operator, but the output of the binary search is wrong. when I try to pass the size of array as an argument then the output is fine. My question is why & what is the problem for calculating array size in function? is it possible to calculate array size in function?
Here is my approach:
...ANSWER
Answered 2021-Jun-12 at 14:47My question is why & what is the problem for calculating array size in function
The problem is that arr is a pointer to an element of the array. The size of the pointer has nothing to do with the size of the array, which is why your attempted sizeof(arr) cannot work.
The warning message also explains this quite well.
is it possible to calculate array size in function?
Given only a pointer to an element, it is generally1 not possible to determine the size of the array. That is why you must pass the size as an argument.
Another approach which I prefer is to encapsulate the pointer and the length in a class. There is a standard class template for this purpose: std::span.
QUESTION
#include
using namespace std;
int binarySearch(int a[], int size, int x, int low, int high){
if(low > high) return -1;
int mid = (low + high)/2;
if(a[mid] == x){
return mid;
}
if(a[mid] < x){
return binarySearch(a, size, x, mid+1, high);
}
else{
return binarySearch(a, size, x, low, mid-1);
}
}
int main(){
int a[] = {1, 2, 3, 4, 5, 6};
int size = sizeof(a) / sizeof(a[0]);

Answered 2021-Jun-10 at 08:00If you don't return from a non-void-return-type function, it'll lead to undefined behavior. Logically it should still function properly, but technically, on some compilers it'll work, on others it might not.
Compiling on gcc with -Wreturn-type enabled will also give you a warning (as you've mentioned):
warning: no return statement in function returning non-void [-Wreturn-type]
