[$] Saving birds with technology

목, 2019/02/07 - 2:26오전

Two members of the Cacophony Project came to linux.conf.au 2019 to give an overview of what the project is doing to increase the amount of bird life in New Zealand. The idea is to use computer vision and machine learning to identify and eventually eliminate predators in order to help bird populations; one measure of success will be the volume and variety of bird song throughout the islands. The endemic avian species in New Zealand evolved without the presence of predatory mammals, so many of them have been decimated by the predation of birds and their eggs. The Cacophony Project is looking at ways to reverse that.

[$] Mozilla's initiatives for non-creepy deep learning

목, 2019/02/07 - 12:13오전
Jack Moffitt started off his 2019 linux.conf.au talk by calling attention to Facebook's "Portal" device. It is, he said, a cool product, but raises an important question: why would anybody in their right mind put a surveillance device made by Facebook in their kitchen? There are a lot of devices out there — including the Portal — using deep-learning techniques; they offer useful functionality, but also bring a lot of problems. We as a community need to figure out a way to solve those problems; he was there to highlight a set of Mozilla projects working toward that goal.

[$] Fixing page-cache side channels, second attempt

수, 2019/02/06 - 1:40오전
The kernel's page cache, which holds copies of data stored in filesystems, is crucial to the performance of the system as a whole. But, as has recently been demonstrated, it can also be exploited to learn about what other users in the system are doing and extract information that should be kept secret. In January, the behavior of the mincore() system call was changed in an attempt to close this vulnerability, but that solution was shown to break existing applications while not fully solving the problem. A better solution will have to wait for the 5.1 development cycle, but the shape of the proposed changes has started to come into focus.

[$] Python elects a steering council

화, 2019/02/05 - 6:04오전

After a two-week voting period, which followed a two-week nomination window, Python now has its governance back in place—with a familiar name in the mix. As specified in PEP 13 ("Python Language Governance"), five nominees were elected to the steering council, which will govern the language moving forward. It may come as a surprise to some that Guido van Rossum, whose resignation as benevolent dictator for life (BDFL) led to the need for a new governance model and, ultimately, to the vote for a council, was one of the 17 candidates. It is perhaps much less surprising that he was elected to share the duties he once wielded solo.

[$] Rusty's reminiscences

토, 2019/02/02 - 7:45오전
Rusty Russell was one of the first developers paid to work on the Linux kernel and the founder of the conference now known as linux.conf.au (LCA); he is one of the most highly respected figures in the Australian free-software community. The 2019 LCA was the 20th edition of this long-lived event; the organizers felt that it was an appropriate time to invite Russell to deliver the closing keynote talk. He used the opportunity to review his path into free software and the creation of LCA, but first a change of clothing was required.

[$] Design for security

목, 2019/01/31 - 6:01오전

Serena Chen began her talk in the Security, Identity & Privacy miniconf at linux.conf.au 2019 with a plan to dispel a pervasive myth that "usability and security are mutually exclusive". She hoped that by the end of her talk, she could convince the audience that the opposite is true: good user experience design and good security cannot exist without each other. It makes sense, she said, because a secure system must be reliable and controllable, which means it must be usable, while a usable system must be less confusing, thus it is more secure.

Dana Lewis said that her keynote at linux.conf.au 2019 would be about her journey of learning about open source and how it could be applied in the healthcare world. She hoped it might lead some attendees to use their talents on solutions for healthcare. Her efforts and those of others in the community have led to a much better quality of life for a number of those who suffer from a chronic, time-consuming disease.
