CORS When you work whit services on a different domain, the horror and pain from fighting with CORS are unavoidable. Exactly, was unavoidable, before I discover how to prevent browsers to send “silly” preflight OPTIONS request. I was desperately trying everything, middleware, proxying requests, and accepting and dropping OPTIONS requests on the server side. But when you don’t have control on the server side, […]

Software is licenced under MIT Readme.md from Git vue-cv CV & Resume created with Vue and JSON Vue is best javascript framework I’ve ever been learned. For that […]
This is the original article on GitHub site. After you’ve checked for existing SSH keys, you can generate a new SSH key to use for authentication, then add it to the ssh-agent. If you don’t already have an SSH key, you must generate a new SSH key. If you’re unsure whether you already have an SSH key, check for existing keys. If […]
Network monitoring on Linux This post mentions some Linux command line tools that can be used to monitor the network usage. These tools monitor the traffic flowing through network interfaces and measure the speed at which data is currently being transferred. Incoming and outgoing traffic is shown separately. Some of the commands, show the bandwidth used by individual processes. This […]
Quite a few frameworks have built-in HTTP APIs. Angular 2 has the http module, JQuery has $.ajax, and, up until Vue 2.0, Vue.js had vue-resource. In Vue 2.0, the developers decided that having a built-in http client module was rather redundant, and could be better serviced by third-party libraries. The alternative most frequently recommended is Axios. Axios is a great http client library. It uses promises by default and runs on both the client […]
My way of adding project to GitHub This is my shortest possible explanation, I am glad if someone finds this post useful. This is for Linux users. For Win and Mac user you can find instructions here, on the original GitHub documentation. Create a new repository on GitHub.

.htaccess A .htaccess file is a directory-level configuration file for Apache HTTP server, which allows one to override the web server’s system-wide settings without modifying the global configuration file (e.g., httpd.conf or apache2.conf). Things like per-directory access control, password protection, URL redirection or hotlink prevention can be configured in the .htaccess file. You should avoid using file.htaccess completely if you have […]
If your server has multiple hostnames that resolve to a single address, and you want to respond differently for www.example.com and www.example.org. Creating virtual host configurations on your Apache server does not magically cause DNS entries to be created for those hostnames. You must have the names in DNS, resolving to your IP address, or nobody else will be able to see your website. You […]
