    PRTG Catches Network Issues Before They Cause Downtime

    Threshold-based alerts flag problems early, so your team can act before users notice, not after.

    Reactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.

    Random Color

    Random Color

    A tiny script for generating attractive colors

    A color gen­er­a­tor for JavaScript. There are lots of clever one-lin­ers for gen­er­at­ing ran­dom col­ors. Unfortunately, this code nat­u­rally pro­duces murky greys, browns and greens. ran­dom­Color gen­er­ates at­trac­tive col­ors by de­fault. More specif­i­cally, ran­dom­Color pro­duces bright col­ors with a rea­son­ably high sat­u­ra­tion. This makes ran­dom­Color par­tic­u­larly use­ful for data vi­su­al­iza­tions and gen­er­a­tive art. Once you’ve in­cluded ran­dom­Color.js on your page, call­ing ran­dom­Color() will re­turn a ran­dom at­trac­tive color. Beneath is the out­put of ran­dom­Color called 54 times. You can also pass an op­tions ob­ject to ran­dom­Color. This al­lows you to spec­ify the hue, lu­mi­nos­ity and the num­ber of col­ors to gen­er­ate.

    Gutenberg Typography Kit

    Gutenberg Typography Kit

    A meaningful web typography starter kit

    Gutenberg is a flexible and simple-to-use web typography starter kit for web designers and developers. It’s a small step towards a better typography on the web. Beautiful typographic styles can be made by setting base type size, line height (leading), and measure (max-width). Gutenberg is a work-in-progress project by Matej Latin that brings meaning and craftsmanship to web typography. The reader should be able to read the message of a text easily and comfortably. This depends to a not inconsiderable extent on the size of the type, the length of the lines and the leading. Gutenberg sets the baseline grid to establish a proper vertical rhythm and makes sure all elements fit into it. It sets up the macro typography so you can focus on the micro–typographic details. All calculations in Gutenberg depend on base type size and line-height. Multiplication of these two results in leading which is essential for setting a correct vertical rhythm and a baseline grid.
