#1: Let Me Contain That For You
Straight from Google, lmctfy (pronounced lem-kut-fee) is the open-source version of Google’s Linux application container stack. The vaguely French-sounding containers allow for the isolation of resources used by multiple apps running on a single machine, giving them the impression of running exclusively. Google’s latest project aims to provide container abstraction through a high-level API built around user intent.

#2: Joblint

This barometer of sorts by Rowan Manning simplifies the job hunt by testing job specs for issues with sexism, culture, expectations or “recruiter fails.” Whether you’re a recruiter looking to make a job spec more attractive to a broad range of candidates, or a developer looking to filter out bad opportunities, Joblint can tip the scales.

#3: Mapsicon
Mapsicon is a free collection of maps of almost every country in the world. This online atlas by Régis Freyd has maps available in 11 sizes, ranging from 16×16 to 1024×1024 pixels, plus SVG formats. Freyd created all the icons using Adobe Fireworks, intending them more as project illustrations or placeholders than replacements for extremely detailed, precise world maps.

#4: fullPage.js
Exactly what it sounds like, fullPage is a simple and easy plug-in to create full-screen scrolling (a.k.a. single-page) websites. Written in JavaScript by Alvaro Trigo, the plug-in also adds landscape sliders inside site sections. Not much more to it, really. Trigo was going for simple and easy, and that’s what fullPage is.

#5: Semantic UI was featured in one of our previous Top 5 lists.
