I've been looking for something to find in webtechnologies, which will allow me to get interesting information about the user's computer. I needed something on the client-side. After a tedious search, I used Javascript for common things like operating system, resolving, browser. I have also encountered WebGL technology that works exclusively under Chrome, but it offers a deeper view of the user's computer. WebGL can detect the depth of the color buffer, the number of processor cores, including virtual ones, the name of the DirectX graphics card. The application utilizes a total of 8 javascript files that allow you to obtain this specific information about the client's hardware. The web app also works on Android smartphones. Note the interesting thing that computers have a 24-bit buffer and Android phones 32-bit. Where does this application have use? Internet contests for the most powerful graphics card, player rankings based on graphics card and processor cores, O

Today, we will devote our microcontroller and its general use to a rather unusual purpose. Specifically, I will be talking about how I made a microcontroller from a webscraper. (If this can be called when processing your own backend information). As many of you know, a web scraper is a device that performs the task of retrieving information from that web site. The most wanted information from websites is e-mail addresses, phone numbers. Recently, however, this phenomenon is also used for a variety of statistical tasks where the scraper receives data on products, their prices, and evaluates them. Even similar devices are used as robots for trading with cryptomas or common names. At the most appropriate time (statistically) the robot pedal and bought another - a suitable menu with a rising tendency. In my case, I was interested in getting information from websites, specifically phone numbers and email addresses. We will therefore go directly to the realization. I have used 3 kinds

Hello everyone, today we look at how to easily send e-mails through Arduino using a webserver on internet. We will use Arduino with W5100 Ethernet shield and ESP8266 dev board - NodeMCU in the client mode to send emails through the PHP script that the microcontroller will attach to the client. We will send text that will be pre-defined in the php file to be sent to the specified mail. Most web hosting sites also support extensions as a mail feature, allowing for communication with the SMTP server on localhost (at webhosting service). So we will use the external website on internet that have local SMTP server. With PHP mail function, we can send emails to different email addresses directly from the web site, sending them to the email address of the domain's registrar (your e-mail address) from which these emails will be sent a.k.a. pre-defined e-mail. Tested hostings: php5.sk, sweb.cz PHP file on which we will make request: <?php $msg= "Hello Word!" ; $msg= wor
