Get the correct number of CPU cores on a Linux Debian server: grep "cpu cores" /proc/cpuinfo |sort -u |cut -d":" -f2 | awk ‘{s+=$1} END {print s}’grep "cpu cores" /proc/cpuinfo |sort -u |cut -d":" -f2 | awk ‘{s+=$1} END {print s}’ Here is an example output on an AMD Ryzen 5 3600 Hexa-Core: 66 That […]
While using request package with a NodeJS script I noticed it was causing a lot of errors like ETIMEDOUT, ESOCKETTIMEDOUT and also getaddrinfo ENOTFOUND after some HTTP requests on the same URL.

You can submit a form using jQuery .trigger() function: $(‘#myForm’).submit(function (e, pass_through) { if(typeof bypass_checks == ‘undefined’ || bypass_checks == false) { e.preventDefault(e); // Do some Ajax checks here $(‘#myForm’).trigger("submit", [true]); } });$(‘#myForm’).submit(function (e, pass_through) { if(typeof bypass_checks == ‘undefined’ || bypass_checks == false) { e.preventDefault(e); // Do some Ajax checks here $(‘#myForm’).trigger("submit", […]
You can set strictSSL to false on NodeJs request: var options = { url: ‘http://url’, strictSSL: false } request(options, function(err, resp, body) {});var options = { url: ‘http://url’, strictSSL: false } request(options, function(err, resp, body) {}); More information can be found here: https://github.com/request/request#user-content-requestoptions-callback strictSSL – if true, requires SSL certificates be valid.

You can modify the default request timeout like this: var options = { url: ‘https://www.google.com/’, timeout: 120000 } request(options, function(err, resp, body) {});var options = { url: ‘https://www.google.com/’, timeout: 120000 } request(options, function(err, resp, body) {}); Details of the param timeout can be found here: https://github.com/request/request#user-content-requestoptions-callback timeout – integer containing number of milliseconds, controls […]
With Google Cloud Logs Viewer you can perform advanced logs queries to search, for example, all Load Balancer requests that returned a status code different from 200 (useful to spot connection errors) or you can search all requests where the URL contains a specific string. The official documentation is here: https://cloud.google.com/logging/docs/view/advanced-queries Available search operators: = […]
Here is a quick example of using jQuery .serializeArray() function and then convert all the serialized data into an array, so you can easily access single POST values: $(document).ready(function() { $("form").submit(function(e){ e.preventDefault(e); var fieldsArray = $("form").serializeArray(); fieldsLen = fieldsArray.length; fieldsObj = {}; for (i=0; i<fieldsLen; i++) { fieldsObj[fieldsArray[i].name] = fieldsArray[i].value; } […]
