The main reason to switch is that IPv4 only allows around 4 billion internet addresses. In order for one device to communicate with another on the internet each of them has to have a unique internet address (IP address). With the number of devices currently on the market – computers, smartphones, smart tvs and set-top boxes – we are already out of addresses. However, clever manipulation allows some devices to share IP addresses with other devices, but this is not an ideal situation. The sharing of addresses makes it difficult for devices to communicate freely on the internet, thus limited functionality.
IPv6 solves the IP address issue simply by introducing a new type of IP address that can handle 3.4e+38 – or 4 billion times 4 billion times 4 billion times 4 billion. It a huge number – difficult for most people to understand. But lets just assume that we will not be running out of IP address ever again.
Today (6/6/12) was been chosen by the Internet Society to mark the launch of IPv6 . IPv6 has been around for many years but the deployment very limited – and mainly used for research within companies and institutions. ISP, hosting providers and other companies on the internet have been repluctant to start offering services on IPv6, primarily because of the investment required both in hardware, software and training.
The Internet Society on the other hand has tried to initiate a movement encouraging ISP, webiste and hardware vendors to take the leap to IPv6 anyway – and thus promote their businesses by using cutting-edge technology.
Another reason why IPv6 has taken such a long time to be accepted is that it is not compatible with IPv4, even though they can exist side by side. But not being compatible means that every piece of software communicating on the internet has to be re-written to support IPv6. The communities around each of the open source projects have a natural interest to support new features; and many projects strive to be forerunners in these areas.
On Open Source Alternative we have tagged each open source project that supports IPv6 with an IPv6 tag – making it easy to see and search for software that supports IPv6. A list of all IPv6 enabled open source projects is available here: Open source alternatives with IPv6 support
One of the most important projects is Apache – the open source web asian gay hookup app server that hosts almost 2/3 of all websites on the internet. Apache is also the web server used by Open Source Alternative to make our website available on both IPv4 and IPv6. The software, however, gets you nowhere, unless your hosting provider also supports IPv6, which is the reason why Osalt switched to Linode VPS for great hosting and IPv6 connectivity to the internet.
It has a GUI (graphical user interface) based on Qt framework and its 3D viewer allows quick rendering of 3D scenes
On the other end of a connection to an IPv6 webserver is of course an IPv6 web browser. Again, the open source community has the answer in terms of Firefox and Google Chrome.
Nevernote was created in response to popular demand of Linux users. A clone of Evernote, it was originally intended for Linux but can also run on Windows. Nevernote is a note-saving program that also lets you save photos, sound files and documents.
One of the first things a person will notice is that the interface, written in Java, is not slick and attractive. It is, however, very functional and does exactly what it is supposed to do. The interface is very easy to interact with and largely self-explanatory, making for a very short learning time. You’ll see different sorting options; for instance, if you click on a tag like “business meetings” you will see all the notes you’ve made for that subject as well as photos you took of presentation material, etc. In the largest space on the screen the actual note you selected appears.
Nevernote will sync your notes and other saves across all your computer, iPad and SmartPhone. You can save notes, photos, anything you see or hear and even leave yourself a voice memo if you like. Just type a note and it is saved automatically.
At this time, Nevernote doesn’t have Ink Notes; you cannot write in cursive or print and have it show up on your Android or be able to edit them on your iPad. However, you can make ink notes on your computer and file them for future reference. You will also find that the search function is adequate but the more specific you are in titling your notes the easier it is for the search function to find them.
Nevernote is an easy to use, viable alternative to those Linux users who want a program nearly exactly like Evernote.
For instance, FreeCAD has a plugin/module framework, divided into the core software and modules that can be added when they are needed. Geometry types and nearly all the tools are stored in the modules that can be added or taken off as needed. Tools are grouped around workbenches so that only the tools you need are displayed according to the task you are doing. This provides an uncluttered workspace that is both functional and easy to work with.
This 3D CAD modeler has the ability to sketch in 2D or to take details from a 3D model and create 2D production drawings. Its focus is not specifically on 2D drawings or animation although it does have advanced motion simulation features; it is very adaptable and can be used in a broader area than software like Cinema 4D or Maya.
Luckily, a lot of software already supports IPv6 – and especially open source software
A user can create a collection of parts and manipulate it with open or closed 3D loops. The parts can be connected with motors, springs, joints, torques or gravity; a multibody dynamics analysis can be used to predict its motion according to the laws of gravity.
