ZFS in Linux and BSD

  • ZFS On Linux Runs Into A Snag With Linux 5.0

    While the Linux 5.0 kernel has a lot of enticing features and improvements, if you rely upon ZFS On Linux (ZOL) you will probably want to hold off on trying the Linux 5.0 release candidates at this time.

    ZFS On Linux currently fails to build against the Linux 5.0 kernel sources. This isn't due to a trivial API change but rather the 5.0 kernel is no longer exporting the __kernel_fpu_begin and __kernel_fpu_end symbols, which the ZOL kernel module relies upon as part of the file-system's checksums.

    There isn't a simple solution for this immediately, especially one that doesn't involve using GPL symbols, due to license compatibility issues with the out-of-tree ZOL kernel code. But surely with time and new code a solution can come about as it doesn't look like the upstream kernel developers are interested in any maneuvering to help out ZOL specifically (or rarely out-of-tree modules for that matter).

  • [Older] The future of ZFS in FreeBSD

    The sources for FreeBSD's ZFS support are currently taken directly from Illumos with local ifdefs to support the peculiarities of FreeBSD where the Solaris Portability Layer (SPL) shims fall short. FreeBSD has regularly pulled changes from Illumos and tried to push back any bug fixes and new features done in the context of FreeBSD. In the past few years the vast majority of new development in ZFS has taken place in DelphixOS and zfsonlinux (ZoL). Earlier this year Delphix announced that they will be moving to ZoL

Software: Genome Browsers, EtherCalc and Curl

  • Best Free Web Based Genome Browsers

    In the fields of molecular biology and genetics, a genome is the genetic material of an organism. It consists of DNA (or RNA in RNA viruses). Each genome contains all of the information needed to build and maintain that organism. In humans, a copy of the entire genome—more than 3 billion DNA base pairs—is contained in all cells that have a nucleus. The study of the genome is called genomics. In bioinformatics, a genome browser is a graphical interface for display of information from a biological database for genomic data. They are important tools for studying genomes given the vast amounts of data available. They typically load very large files, such as whole genome FASTA files and display them in a way that users can make sense of the information there. They can be used to visualize a variety of different data types. Genome browsers enable researchers to visualize and browse entire genomes with annotated data including gene prediction and structure, proteins, expression, regulation, variation, comparative analysis, etc. They use a visual, high-level overview of complex data in a form that can be grasped at a glance and provide the means to explore the data in increasing resolution from megabase scales down to the level of individual elements of the DNA sequence. There’s a wide range of web based genome browsers. We’re going to restrict our selection to the top 4.

  • Daniel Stenberg: curl 7.65.2 fixes even more

    Six weeks after our previous bug-fix release, we ship a second release in a row with nothing but bug-fixes. We call it 7.65.2. We decided to go through this full release cycle with a focus on fixing bugs (and not merge any new features) since even after 7.65.1 shipped as a bug-fix only release we still seemed to get reports indicating problems we wanted fixed once and for all. Download curl from curl.haxx.se as always! Also, I personally had a vacation already planned to happen during this period (and I did) so it worked out pretty good to take this cycle as a slightly calmer one. Of the numbers below, we can especially celebrate that we’ve now received code commits by more than 700 persons!
