Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Send and receive message remotely with ESP8266
The result is that the WiFiSecureClient doesn't work when used in the bot declaration, so I changed the variable to WiFiClient but I can't use the certificate, so I comment it out and ESP8266.h gives me a thousand errors due to lack of dependencies in its libraries. I should point out that I downloaded the entire project from the Arduino ESP8266, I don't know how to link all the libraries, so I simply took those from the ESP8266WiFi.

Do you have any idea why this program would not work? [ESP32]
#include #include "time.h" #include "sntp.h" char* ssid = "WIFI"; char* password = "w1fi"; const char* ntpServer1 = "pool.ntp.org"; const char* ntpServer2 = "time.nist.gov"; const long gmtOffset_sec = 3600; const int daylightOffset_sec = 3600; const char* time_zone = "CET-1CEST,M3.5.0,M10.5.0/3"; // TimeZone rule for Europe/Rome including daylight adjustment rules (optional) void printLocalTime() { struct tm timeinfo; if(!getLocalTime(&timeinfo)){ Serial.println("No time available (yet)"); return; } Serial.println(&timeinfo, "%A, %B %d %Y %H:%M:%S"); } // Callback function (get's called when time adjusts via NTP) void timeavailable(struct timeval *t) { Serial.println("Got time adjustment from NTP!"); printLocalTime(); } void setup() { Serial.begin(115200); // set notification call-back function sntp_set_time_sync_notification_cb( timeavailable ); /** * NTP server address could be aquired via DHCP, * * NOTE: This call should be made BEFORE esp32 aquires IP address via DHCP, * otherwise SNTP option 42 would be rejected by default. * NOTE: configTime() function call if made AFTER DHCP-client run * will OVERRIDE aquired NTP server address */ //sntp_servermode_dhcp(1); // (optional) /** * This will set configured ntp servers and constant TimeZone/daylightOffset * should be OK if your time zone does not need to adjust daylightOffset twice a year, * in such a case time adjustment won't be handled automagicaly. */ configTime(gmtOffset_sec, daylightOffset_sec, ntpServer1, ntpServer2); /** * A more convenient approach to handle TimeZones with daylightOffset * would be to specify a environmnet variable with TimeZone definition including daylight adjustmnet rules. * A list of rules for your zone could be obtained from https://github.com/esp8266/Arduino/blob/master/cores/esp8266/TZ.h */ //configTzTime(time_zone, ntpServer1, ntpServer2); //connect to WiFi Serial.printf("Connecting to %s ", ssid); WiFi.begin(ssid, password); while (WiFi.status() != WL_CONNECTED) { delay(500); Serial.print("."); } Serial.println(" CONNECTED"); } void loop() { delay(5000); printLocalTime(); // it will take some time to sync time :) }

How do you determine what module/s do you have on your boards or vice versa?

Programming esp32
He meant the Arduino framework. There is an Arduino core for the ESP8266 so you can use Arduino’s IDE and libraries for the ESP with this core here
- rst cause:2, boot mode:(3,6) ERROR :(

Help Needed: ESP NOW between ESP Wroom 32 DevKit and WeMos D1 Mini.
According to this link(https://github.com/esp8266/Arduino/issues/6174) WeMos can't receive broadcasts on SDK 2.2.1.

ESP8266 on ESPNow protocol power consumption/sleep mode
There are 2 ways to minimize power consumption while maintaining an active WiFi connection, but it's not a large power reduction for either mode. Look at Automatic Modem Sleep and Automatic Light Sleep here: https://github.com/esp8266/Arduino/tree/master/libraries/esp8266/examples/LowPowerDemo
- Very unique color clock! Details on https://www.instructables.com/Pingo-Color-Clock-by-Illusionmanager/

lolin boards in close proximity are causing WIFI interferance
That's the Arduino (Uno) library. If you've correctly installed the ESP8266 package then it should be 3.(something-ish) for the ESP8266 version of the WiFi library. Current is 3.1.1 for the core files, and the WiFi is part of the core libraries. If you have your compile options set for verbose then you should see it doesn't access that old Arduino WiFi library.

Is there any way to get a low battery alert from a D1 mini?
Seems it's expected https://github.com/esp8266/Arduino/issues/721

Verified Curl
Again, strange attitude, given that he personally had legal issues with US in the past, the reasons for which were never disclosed[1].
Typical good developers are not Rambo. When law enforcers come to them and force them at gunpoint to make them commit/add a new maintainer, they should not expect active resistance. Minor reminder: curl is not just some http library, they maintain their own CA list[2]. They don't need any intricate hidden lines for backdoor, CA list is a backdoor on its own.

I make the same mistake too, sometimes.
Here are some examples from the ones on most Linux distros (Apple and Microsoft's lists are very similar):
-
Kreait php realtime database cannot get reference!! (cURL 60 error).
Go to the cURL official site and download the latest cacert.pem file. It's linked near the top of this page: https://curl.se/docs/caextract.html
- How come cURL Is Not Outputting?
-
Add trusted root certificate for POST requests (LetsEncrypt)
Haven't tried it myself but curl offers the certificate store used by Mozilla Firefox as a download.

ND/NGD : Let's Encrypt root certificate expiration thread!
I used the cacert.pem from https://curl.se/docs/caextract.html, as suggested by the NZBGet documentation. Is there a difference between these two cacert.pem files? Is one better than the other?
-
Did the Let's Encrypt DST CA X3 Root Certificate expiration break anything for you? On Debian 8 (which you should have deprecated by now), you'll have to disable it as well as install the new ISRG certificate or else it will show all Let's Encrypt Certificates as expired.
https://curl.se/docs/caextract.html and running update-ca-certificates
- I feel like this should be simple??
- Xampp works on my desktop but not on my laptop. More in comments
