How to send bulk calendar invites?

20 March 2026 @ 7:32 am

want to: Send invites in bulk Personalize each invite (name, details, etc.) Ensure it works across Google Calendar and Outlook One approach I found is using APIs that handle calendar invite generation and delivery. For example, platforms like Let’s Calendar provide APIs to send bulk invites, personalize them, and manage delivery across different calendar systems. Are there any other recommended approaches or best practices for handling this efficiently? Any guidance would be helpful.

Replacing part of a character string in Perl

20 March 2026 @ 6:59 am

The is a rewrite of my previous post on the same subject with, hopefully, a clearer MWE. The issue is to replace "Rain" in the string "RainOb" by "Temp" so that the string becomes "TempOb". subsequently this has to be modified to "WindOb" and "HumOb" and back to "RainOb". #!/usr/bin/perl use strict; use warnings; my @lines=<DATA>; my $var1="Temp"; foreach my $line(@lines){ if($line =~ m/plot\(df/){ if($line =~ m/color='b'/){ #$line =~ s/"(?<=\w)(Ob)"/"${var1}"/; #no error, no change effected $line=ax[0,0].plot(df['Date'], df["${var1}Ob"], color='b', label="${var1}Ob"); #syntax error at line 14, near "ax[" print "$line\n"; exit; } if($line =~ m/color='r'/){ $line =~ s/"(?<=\w)(Ob)"/"${var1}"/; #This remains u

No Certified Authority template works for auto-enrollment but one

20 March 2026 @ 6:56 am

For context, we're setting up a new forest from the ground up. We only have two domains attached to it, however that's not what is important. Two weeks ago I set up the ADCA and duplicated the implicit "Computer Authentication" template making it universal for basically everything in our domain (DCs, users, services, computers), now, that is not secure and I wanted to make one template for each need and manage them through security groups. However, for some reason, auto-enrollment fails, I can manually "install" the certificates on the clients and it works great, but auto-enrollment fails and I have no clue why. I tried making the settings 1-1 to the old template and it doesn't work, however, if I try duplicating my first template (the one I made, not computers) and then changing the settings, it works. It's not due to permissions since I've tried setting up the a template with the same exact settings as the one that works and it doesn't.

Clang++ linker failed [duplicate]

I don't know much C++, so I decided to write a simple script to refresh my knowledge. So, I have two .cpp files (for example they called): dir/include.cpp и main.cpp. dir/include.h #include <iostream> #include <vector> using std::cout, std::endl; using std::vector; template<typename T> void printVector<T>(vector<T> &vt); dir/include.cpp #include "include.h" template<typeame T> void printVector(vector<T> &vt) { for (auto t : vt) cout << t << " "; cout << endl; } main.cpp #include "dir/include.h" int main() { vector<int> vi{1, 2, 3, 4, 5}; printVector<int&g

How to authenticate with GridDB Cloud REST API using API key vs Basic Auth?

20 March 2026 @ 6:42 am

I'm trying to query data from GridDB Cloud using its REST/WebAPI endpoint. The official docs mention both Basic Authentication and API key-based access, but I'm unclear on the exact header format and which method is preferred for production use. For Basic Auth, I've tried the following: import requests import base64 credentials = base64.b64encode(b"admin:mypassword").decode("utf-8") headers = { "Authorization": f"Basic {credentials}", "Content-Type": "application/json" } url = "https://<cluster-host>/griddb/v2/<cluster-name>/dbs/public/containers" response = requests.get(url, headers=headers) print(response.status_code, response.text) I consistently receive a 401 Unauthorized response. Is the cluster hostname format <clusterName>.griddb.net or something else for the GridDB Cloud Free Plan? Does GridDB Cloud Free Pla

I think I'm close however refuse to look up answers online and just copy and paste a solution. Can someone have a look at this code and make suggestions. This is for a number guessing game. Hopefully someone is able to run the code and identify issue quickly. Thanks in advance. import os import random os.system("clear") # Select number using random num = random.randint(1, 100) print (num) count = 1 # Input first guess of 5 guess = input ("Enter a number between 1 and 100: " ) while (count < 6): if count == 5: print ("You lose!!!") elif int(guess) < num: print ("Your number is too low.
