With the help of some advanced selectors a dropdown menu can be easily created with CSS. Throw in some fancy CSS3 properties and you can create a design that was once only achievable with background images and Javascript. Follow this tutorial to see the step by step process of building your own pure CSS dropdown menu.

RStudio provides open source and enterprise-ready professional software for the R statistical computing environment. We started RStudio because we were excited and inspired by R. RStudio products, including RStudio IDE and the web application framework RStudio Shiny, simplify R application creation and web deployment for data scientists and data analysts.

This site looks like an interesting resource to find useful open source packages. Webmin is listed as second in this list of 7 control panels. I have been using Webmin forever but might try out ISPConfig. Although something is listed on this site I always download packages from sourceforge.net.
As demonstrated, this vulnerability wasn’t a result of insufficient system testing; it was because of insufficient unit testing. Keith Ray himself wrote a “Testing on the Toilet”8 article, “Too Many Tests,”11 explaining how to break complex logic into small, testable functions to avoid a combinatorial explosion of inputs and still achieve coverage of critical corner cases (“equivalence class partitioning”). Given the complexity of the TLS algorithm, unit testing should be the first line of defense, not system testing. When six copies of the same algorithm exist, system testers are primed for failure.
When using the Cordova APIs, an app can be built without any native code (Java, Objective-C, etc) from the app developer. Instead, web technologies are used, and they are hosted in the app itself locally (generally not on a remote http server).
And because these JavaScript APIs are consistent across multiple device platforms and built on web standards, the app should be portable to other device platforms with minimal to no changes.

The Utilite can have the processor configured up to 1.2GHz, up to 4GB of DDR3 RAM, up to a 512GB mSATA SSD, up to a 128GB Micro-SD SDXC, and two display ports — HDMI 1.4 and DVI-D — up to 1920×1200 resolution at 60Hz. The specs of the GPU aren’t listed, but rather what is listed is what it supports: OpenGL ES 1.1 and 2.0, OpenVG 1.1 and OpenCL EP, multi-stream 1080p H.264, VC1, RV10, and DivX HW decoding. What seems static on the Utilite, at least, is Bluetooth 3.0, two Gigabit Ethernet ports, 802.11b/g/n WiFi, stereo line-out and in, four USB 2.0 ports, a micro-USB OTG connector, and two RS232 serial ports.

So then a bug shows up which leaks the content of memory mishandled by that layer. If the memoory had been properly returned via free, it would likely have been handed to munmap, and triggered a daemon crash instead of leaking your keys.

The MinnowBoard Max will go on sale early in the third quarter. Two versions will be offered initially: a $99 entry-level model, with a 1.46GHz single-core E3815 SoC and 1GB RAM; and a $129 model, equipped with a 1.33GHz dual-core E3825 SoC and 2GB RAM. Additional details will soon be available at Minnowboard.org as well as at CircuitCo’s MinnowBoard product page.

Graphics give games a visual appeal, but it’s the internal physics engine that gives the game’s world life. A physics engine is a software component that provides a simulation of a physical system. This simulation can include soft- and rigid-body dynamics, fluid dynamics, and collision detection. The open source community has a number of useful physics engines operating in the 2D and 3D domains targeted to games and simulations. This article introduces the use and basics of a physics engine and explores two options that exist: Box2D and Bullet.

One of the most common questions I get asked is how to get started with data visualisations. Beyond following blogs, you need to practise – and to practise, you need to understand the tools available. In this article, I want to introduce you to 20 different tools for creating visualisations: from simple charts to complex graphs, maps and infographics. Almost everything here is available for free, and some you have probably installed already.
