  • Semantic Placement in Augmented Reality using MrEd

    In this article we’re going to take a brief look at how we may want to think about placement of objects in Augmented Reality.

    Designers often express ideas in a domain appropriate language. For example a designer may say “place that chair on the floor” or “hang that photo at eye level on the wall”.

    However when we finalize a virtual scene in 3d we often keep only the literal or absolute XYZ position of elements and throw out the original intent - the deeper reason why an object ended up in a certain position.

    It turns out that it’s worth keeping the intention - so that when AR scenes are re-created for new participants or in new physical locations that the scenes still “work” - that they still are satisfying experiences - even if some aspects change.

    In a sense this recognizes the Japanese term 'Wabi-Sabi'; that aesthetic placement is always imperfect and contends between fickle forces. Describing placement in terms of semantic intent is also similar to responsive design on the web or the idea of design patterns as described by Christopher Alexander.

  • ArangoDB: Three Databases in One

    ArangoDB, a German database expanding its business in the United States, has released new capabilities in version 3.5 of its eponymous database management software to make it easier to query and search growing data sets across multiple data models.

    Multimodel databases take on the issue of effectively using data stored in different ways, but also of managing multiple databases, each with its own storage and operational requirements, including data consistency.

    With ArangoDB, data can be stored as key-value pairs, graphs or documents and accessed with one declarative query language. And you can do both at the same time — a document query and a graph query. The combination offers flexibility and performance advantages, explained Claudius Weinberger, CEO.

  • Open Source Is Poised To Have A Greater Impact On Security [iophk: marketeering]

    Falco, another open source security project, is a native runtime protection/detection tool for hosts and containers. It lives right in the container environment and can ascertain everything going on by watching system calls, obviating the need for agents in each container. It also provides rich out-of-box policies/rules that can be used to detect anomalous behavior in different levels, including the host, container and cluster levels.

10 Open Source Static Site Generators to Create Fast and Resource-Friendly Websites

Technically, a static website means the webpages are not generated on the server dynamically. The HTML, CSS, JavaScript lie on the server in the version the end user receives it. The raw source code files are already prebuilt, the source code doesn’t change with the next server request. It’s FOSS is a dynamic website which depends on several databases and the web pages are generated and served when there’s a request from your browser. Majority of the web is powered by dynamic sites where you interact with the websites and there are plenty of content that often change. Read more

7 Amazing Linux Distributions For Kids

Linux is a very powerful operating system and that is one of the reasons why it powers a lot of servers on the Internet. Though there have been concerns about its user-friendliness which has brought about the debate of how it will overtake Mac OSX and Windows on desktop computers, I think users need to accept Linux as it is to realize its real power. Today, Linux powers a lot of machines out there, from mobile phones to tablets, laptops, workstations, servers, supercomputers, cars, air traffic control systems, refrigerators, and many more. With all this and more yet to come in the near future, as I had already stated at the beginning, Linux is the operating system for future computing. Because the future belongs to the kids of today, then introducing them to technologies that will change the future is the way to go. Therefore they have to be introduced at an early stage to start learning computer technologies and Linux as a special case. One thing common to children is curiosity and early learning can help instill a character of exploration in them when the learning environment is designed to suit them. Having looked at some quick reasons why kids should learn Linux, let us now go through a list of exciting Linux distributions that you can introduce your kids to so that they can start using and learning Linux.
