  • Oracle's Kernel Test Framework Might Be Added To The Linux Kernel Tree

    Knut Omang of Oracle is working on integrating the Kernel Test Framework into the Linux kernel source tree/repository.

    The Kernel Test Framework is used for unit testing of the Linux kernel as well as different component testing of the code. Up to this point the Kernel Test Framework has been developed separate of the Linux kernel tree in order to allow for testing against arbitrary versions of the Linux kernel. Now, however, Oracle is wanting to get this kernel testing framework as part of the Linux kernel source tree.

  • Essential Developer Guide for Building Blockchain Applications Using Hyperledger Sawtooth

    Hyperledger Sawtooth is an enterprise blockchain platform for building distributed ledger applications and networks. The design philosophy targets keeping ledgers distributed and making smart contracts safe, particularly for enterprise use.

    Sawtooth simplifies blockchain application development by separating the core system from the application domain. Application developers can specify the business rules appropriate for their application, using the language of their choice, without needing to know the underlying design of the core system.

    Sawtooth is also highly modular. This modularity enables enterprises and consortia to make policy decisions that they are best equipped to make. Sawtooth’s core design allows applications to choose the transaction rules, permissioning, and consensus algorithms that support their unique business needs.

Leftovers: Kate, Krita, UCLA Library and RcppExamples

  • Kate - Document Preview Plugin - Maintainer Wanted!

    At the moment the Document Preview plugin that e.g. allows to preview Markdown or other documents layout-ed via embedding a matching KPart is no longer maintained. If you want to step up and keep that plugin alive and kicking, now is your chance!

  • The Sprint

    Hi -)) haven’t posted for some time, because I was busy travelling and coding for the first half of the month. From Aug 5 to Aug 9, I went to the Krita Sprint in Deventer, Netherlands. According to Boud, I was the first person to arrive. My flight took a transit via Hong Kong where some flights were affected due to natural and social factors, but fortunately mine was not one of them. Upon arrival in Amsterdam I got a ticket for the Intercity to Deventer. Railway constructions made me take a transfer via Utrecht Centraal, but that was not a problem at all: the station has escalators going both up to the hall, and down to the platforms (in China you can only go to the hall by stairs or elevator (which is often crowded after you get off)). When I got out of Deventer Station, Boud immediately recognized me (how?!). It was early in the morning, and the street’s quietness was broken by the sound of me dragging my suitcase. Boud led me through Deventer’s crooked streets and alleys to his house. For the next two days people gradually arrived. I met my main mentor Dmitry (magician!) and his tiger, Sagoskatt, which I (and many others) have mistaken for a giraffe. He was even the voice actor for Sago. He had got quite a lot of insights into the code base (according to Boud, “80%”) and solved a number of bugs in Krita (but he said he introduced a lot of bugs, ha!). Also I met David Revoy (my favourite painter!), the author of Pepper and Carrot. And Tiar, our developer who started to work full-time on Krita this year; she had always been volunteering to support other Krita users and always on the IRC and Reddit. And two of other three GSoC students for the year: Blackbeard (just as his face) and Hellozee. Sh_zam could not come and lost communications due to political issues, which was really unfortunate (eh at least now he can be connected). It is feels so good to be able to see so many people in the community – they are so nice! And it is such an experience to hack in a basement church.

  • How UCLA Library preserves rare objects with open source

    The University of California, Los Angeles, (UCLA) Library houses a collection of millions of rare and unique objects, including materials dating from 3000 BCE, that could be damaged, destroyed, or otherwise threatened if they were displayed. To make these special collections widely available while keeping them secure, the UCLA Library has been modernizing its digital repository, which was established 15 years ago on now-outdated software. [...] Watch Jen's Lightning Talk to learn more about the UCLA Library's rare collections digitization project.

  • RcppExamples 0.1.9

    The RcppExamples package provides a handful of short examples detailing by concrete working examples how to set up basic R data structures in C++. It also provides a simple example for packaging with Rcpp.
