  • Overlayfs snapshots

    At the 2017 Vault storage conference, Amir Goldstein gave a talk about using overlayfs in a novel way to create snapshots for the underlying filesystem. His company, CTERA Networks, has used the NEXT3 ext3-based filesystem with snapshots, but customers want to be able to use larger filesystems than those supported by ext3. Thus he turned to overlayfs as a way to add snapshots for XFS and other local filesystems.

    NEXT3 has a number of shortcomings that he wanted to address with overlayfs snapshots. Though it only had a few requirements, which were reasonably well supported, NEXT3 never got upstream. It was ported to ext4, but his employer stuck with the original ext3-based system, so the ext4 version was never really pushed for upstream inclusion.

  • Libreboot Wants Back Into GNU

    Early this morning, Libreboot’s lead developer Leah Rowe posted a notice to the project’s website and a much longer post to the project’s subreddit, indicating that she would like to submit (or resubmit, it’s not clear how that would work at this point) the project to “rejoin the GNU Project.”

    The project had been a part of GNU from May 14 through September 15 of last year, at which time Ms. Rowe very publicly removed the project from GNU while making allegations of misdeeds by both GNU and the Free Software Foundation. Earlier this month, Rowe admitted that she had been dealing with personal issues at the time and had overreacted. The project also indicated that it had reorganized and that Rowe was no longer in full control.

  • Understanding the complexity of copyleft defense

    The fundamental mechanism defending software freedom is copyleft, embodied in GPL. GPL, however, functions only through upholding it--via GPL enforcement. For some, enforcement has been a regular activity for 30 years, but most projects don't enforce: they live with regular violations. Today, even under the Community Principles of GPL Enforcement, GPL enforcement is regularly criticized and questioned. The complex landscape is now impenetrable for developers who wish their code to remain forever free. This talk provides basic history and background information on the topic.

  • After Bill Gates Backs Open Access, Steve Ballmer Discovers The Joys Of Open Data

    A few months ago, we noted that the Gates Foundation has emerged as one of the leaders in requiring the research that it funds to be released as open access and open data -- an interesting application of the money that Bill Gates made from closed-source software. Now it seems that his successor as Microsoft CEO, Steve Ballmer, has had a similar epiphany about openness. Back in 2001, Ballmer famously called GNU/Linux "a cancer". Although he later softened his views on software somewhat, that was largely because he optimistically claimed that the threat to Microsoft from free software was "in the rearview mirror". Not really: today, the Linux-based Android has almost two orders of magnitude more market share than Windows Phone.

  • New Open Door Policy for GitHub Developer Program

    GitHub has opened the doors on its three year old GitHub Developer Program. As of Monday, developers no longer need to have paid accounts to participate.

The new replication features in MySQL 8

Filed under
Server
OSS

This year at the Percona Live open source database conference, I will present a talk on the latest replication features in MySQL 8.0.

It was a huge amount of work to get the MySQL Group Replication plugin out with MySQL 5.7.17. Group Replication is a new plugin that gives the user some nice replication properties by resorting to group communication and state machine replication. This makes the system able to protect data against split brain situations, enables fault-tolerance and high availability, and provides coordination between servers committing transactions that change the data.

In addition to Group Replication, the team has also invested quite a bit on core replication features. Some of these features were already released, and others will be released at some point in time in a MySQL Development Milestone Release (DMR).

  • Event report: FOSSASIA 2017

    FOSSASIA 2017 reminded me of foss.in. After a long time, finally, a conference which has the similar aspects. Similar kind of tight organizing team, the presence of upstream communities from different locations. The participation from the local Singapore tech community along with Hackerspace Singapore is a serious boost. This was my 4th FOSSASIA conference, and also 3rd time in Singapore. I should thank Mario, Hong, and rest of the organizers to make this event a very pleasant experience.

    Our code is available on GitHub at https://github.com/Midburn/. And while it still need to be more tidy, I prefer the release early and often approach. The main idea we want to bring to the Burn infrastructure is using Spark as a database and have already began talking with parallel teams of other burn events. I’ll follow up on our technological agenda / vision. In the mean while, you are more than welcome to comment on the code or join one of the teams (e.g. volunteers module to organize who does which shift during the event).

    Some medicines, however, are too expensive. Some don’t work too well and there are, of course, many terrible diseases for which we have no medicines at all. These issues affect rich and poor nations alike.

  • Should Desktop 3D Printing Be Open Source or Closed Source?

    Open source development has brought a lot of advantages to desktop 3D printing. Is our flirtation with open source a youthful indiscretion that will soon be discarded? Or is open source the key to our recent past and to unlocking the future of 3D printing?

  • How desktop 3D printing's open source platforms shaped the industry's diverse material supply

    Ten years ago, John Kawola remembers the 3D printing industry as a very different place to how it looks today. While still a dynamic field with innovation aplenty, it was dominated by a handful of players. “3D Systems, Stratasys, EOS and EnvisionTEC,” the President of Ultimaker North America lists. Between them, they dominated the 3D printer business, they drove innovation at a rate smaller companies could not keep up with, and they all had a closed materials environment.

  • System76 wants to build its own hardware for its Linux-based computers
    System76 is building up quite a name for itself, being one of a very limited number of companies selling only computers running Linux-based operating systems. Now the aim is to branch out; System76 wants to design and build its own hardware, while representing the open source community as it does so. At the moment, the hardware used in System76 systems is outsourced, but in the future this will change. The company says that it is moving into phase three of its development cycle, and this "moves product design and manufacturing in house." And you should set your expectations high: "We're about to build the Model S of computers. Something so brilliant and beautiful that reviewers will have to add an 11 to their scores."

Beijing Zoo is No Place for Pandas

Pandas in Beijing Zoo
Photo credit: Nick Hopkins

I am a Panda lover. I work as a support engineer in an I.T company here in the United Kingdom. Most of my spare time is spent watching different Panda videos -- both old and new videos. Basically, it is my therapy; a 'stress release' for me. I find them to be adorable and precious creatures. As a matter of fact, I would like to volunteer to come to Sichuan. I want to experience and feel what it's like to be a Panda keeper, to be able to interact with them for real. The Panda is China's National Treasure, so it's a shame to watch the Panda videos from Beijing zoo, as the place is disgusting and not ideal for Pandas to live in (and for sure for all the rest of the animals who unfortunately got stuck in this prison cell).

The place looks like a ghost town. Lifeless and languished. Knowing that Pandas wear a thick fur on their body, can you imagine what it feels for them in 30C or 35C (summer temperature)? What it probably feels like all the time? Come on, if you really care, you must do something now, otherwise these Pandas will die. Please bring them back to their sanctuary where they really belong.

Linux 4.11 File-System Tests: EXT4, F2FS, XFS & Btrfs

With the Linux 4.11 kernel potentially being released as soon as today, here are some fresh benchmarks of Btrfs / EXT4 / F2FS / XFS on a solid-state drive and comparing the performance of 4.11 Git back to Linux 4.9 and 4.10. For those wondering if the block/file-system changes of Linux 4.11 have any impact on EXT4/F2FS/XFS/Btrfs for common I/O workloads or how these file-systems are comparing on this latest kernel, here are some benchmarks.
