    In peer-to-peer environments, peers are often located behind routers which complicates the connection set-up to them. NatTrav provides a common platform for traversal techniques which are used to establish connectivity in these cases. As NatTrav development was stopped quite a while ago, please consider looking at more production-ready libraries like STUN (https://sourceforge.net/projects/stun/). For educational purposes, I still strongly recommend to have a look at both library and example application (chatapp) which are both documented fairly well. To download the latest version of NatTrav, please access the SVN sources in the Code section (project sits in "/nattrav/trunk/").

    Nataly

    Nataly

    A framework that translate name-based pointcut to analysis-based ones

    Nataly, which can translate name-based pointcuts into analysis-based pointcuts automatically. Analysis-based pointcuts, can specify join points through static program analysis. But another problem is that there are few approaches can generate analysis-based pointcuts. We implement Nataly to tackle these two problems with a novel pattern, which is generated by static analysis.

    NextBase

    NextBase – the enterprise level applications development platform.

    NEXTBASE FRAMEWORK Group of enthusiasts are having experience programming various enterprise systems highlighted some conceptual moments that helped with the design of this platform. These moments are the following: The platform supports, along with standard primitive types of data such as text, number, etc., some types that represent objects with certain fields and behavior model. These objects represent complete business modules which carry out a row of interconnected operations and simplifies programming the applications focused on business. For example, there are such objects as Control, The Coordination Block, the Link to the connected document etc. The set of integrated businesss-objects allows to simplify applications programming as much as possible and solve the majority of problems of automation. Documents have access rights for reading and editing at the level

    NoHttp

    NoHttp

    Android implements the Http standard protocol framework

    NoHttp is an Android networking framework that implements common HTTP request, response, caching, cookie, and download workflows. Applications can use HttpURLConnection by default or add the optional OkHttp execution layer. Global configuration controls connection and read timeouts, retries, headers, parameters, SSL behavior, and host verification. Cache data can be stored in a database or on disk, while cookie handling can use built-in or custom stores. The framework supports file downloads with automatic naming and resumable transfer when the server accepts range requests. Its sample application demonstrates cancellation and resume behavior by rebuilding interrupted download requests. The maintainer still supports NoHttp but recommends the newer Kalle framework for new projects.
