  • New Oracle Java 11 Installer For Ubuntu Or Linux Mint (Using Local Oracle Java .tar.gz)

    As many of you already know, Oracle Java requires logging in to an Oracle account to download most versions (all except Oracle Java 12). A while back I created Oracle Java 11 and 12 installer packages (based on the package by Web Upd8), and a PPA for Ubuntu and Linux Mint.

    Since Oracle Java 11 can't be directly downloaded from Oracle any more, the installer no longer works, so I created a new installer that requires the user to create an Oracle account, download the Oracle Java 11 .tar.gz archive (the same version as the installer), and place the archive in /var/cache/oracle-jdk11-installer-local/. After this, you can install the oracle-java11-installer-local package, and it will set up Oracle Java 11 for you.

    Everything else works as before. You can install the oracle-java11-set-default-local package to set Oracle Java 11 as default for example (not only set it as default using a .jinfo file and update-alternatives, but also export the JAVA_HOME environment variable, etc.).

  • My first month on GSoC

    This first month of GSoC was a great learning experience for me, when speaking to my colleagues of how Summer of Code is being important to my professional life, I always respond that I’m finally learning to code and the basic of C++.

    Yes, maybe this is strange, I’m a second year undergraduate Computer Science student, have two year experience with C++. I should have learn to code by now right? Well, at least on my Campus you don’t learn to code applications or how to build stable, clean code. You learn to solve problems, and that’s something I got pretty good at, but when it came to code, well, I’m learning that now and I’m liking it a lot.

  • Snapshot Docker

    The idea of snapshots is to make copies of the current document and allow users to return to them at a later time. This is a part of my whole Google Summer of Code project, which aims to bring Krita a better undo/redo system. When fully implemented, it will fully replace the current mechanism that stores actions with one that stores different states. That is to say, Krita will create a snapshot of the document for every undoable step.

    [...]

    Another interesting thing is the palettes. Krita 4.2.0 allows documents to store their own, local palettes. The palette list is but a QList<KoColorSet *>, meaning that only creating a new QList of the same pointers will not work. This is because, the palettes are controlled by canvas resource manager, which takes the responsibility to delete them. Therefore, when taking snapshots, we had better take deep copies of the KoColorSets. And then another problem comes: the snapshots own their KoColorSets because they are not controlled by the resource manager in any way; but the KisDocument in the view does not. So we have to set up another flag, ownsPaletteList, to tell the document whether it should delete the palettes in the destructor.

    And now the work has shifted to the refactoring of kritaflake, the library that mainly handles vector layers and shapes. I converted the whole KoShape hierarchy to implicit sharing where possible, but some tests are broken. I am now on Windows, where unit tests do not run. I will continue the development of flake as soon as I get access to my Linux laptop.

Neon: A Wannabe Linux Distro For KDE Lovers

KDE Neon is a bit of an oddball Linux thing. Linuxland has an impressive collection of oddball things. Neon looks and feels much like a Linux distribution, but its developers assert quite openly on their website that Neon is not a real Linux distro. It just installs and functions like one -- sort of. That can make deciding to use it a little confusing. Neon appears to be a Linux operating system. It boots your computer. It displays a full desktop environment. It runs *some* applications so you can go about your computing tasks much like using any other -- ahh -- real Linux distribution. That last part is a clue to what makes KDE Neon different. Getting somewhat technical for a minute, KDE Neon is more of a specialty offering than a fully endowed operating system. Other distros support a wide range of applications from the same software format type. For example, Ubuntu runs .Deb formatted packages from the Debian Linux family. All .Deb packages will run on Ubuntu- and other Debian-based distros. Which desktop environment is used does not matter, be it KDE, Xfce, GNOME or whatever. Ditto for RPM-based Linux distributions, like Fedora and Red Hat. All you need is a package management tool or knowledge of the commands for apt, yum or pacman, depending on the distribution's Linux family. However, that is a skill set that lots of Linux users never had to learn. Not so with KDE Neon. Neon runs only a specific category of KDE applications: the latest. Neon's developers assert that their "pseudo" distro does not support most other software. In fact, non-KDE packages most likely will not even install on Neon. Read more

  • Data in a Flash, Part IV: the Future of Memory Technologies

    As it relates to memory technologies, the future looks very promising and very exciting. Will the SSD completely replace the traditional spinning HDD? I doubt it. Look at tape technology. It's still around and continues to find a place in the archival storage space. The HDD most likely will have a similar fate. Although until then, the HDD will continue to compete with the SSD in both price and capacity.

  • Jonathan McDowell: Upgrading my home server

    At the end of last year I decided it was time to upgrade my home server. I built it back in 2013 as an all-in-one device to be my only always-on machine, with some attempt towards low power consumption. It was starting to creak a bit - the motherboard is limited to 16G RAM and the i3-3220T is somewhat ancient (though has served me well). So it was time to think about something more up to date. Additionally since then my needs have changed; my internet connection is VDSL2 (BT Fibre-to-the-Cabinet) so I have an BT HomeHub 5 running OpenWRT to drive that and provide core routing/firewalling. My wifi is provided by a pair of UniFi APs at opposite ends of the house. I also decided I could use something low power to run Kodi and access my ripped DVD collection, rather than having the main machine in the living room. That meant what I wanted was much closer to just a standard server rather than having any special needs. The first thing to consider was a case. My ADSL terminates in what I call the “comms room” - it has the electricity meter / distribution board and gas boiler, as well as being where one of the UniFi’s lives and where the downstairs ethernet terminates. In short it’s the right room for a server to live in. I don’t want a full rack, however, and ideally wanted something that could sit alongside the meter cabinet without protruding from the wall any further. A tower case would have worked, but only if turned sideways, which would have made it a bit awkward to access. I tried in vain to find a wall mount case with side access that was shallow enough, but failed. However in the process I discovered a 4U vertical wall mount. This was about the same depth as the meter cabinet, so an ideal choice. I paired it with a basic 2U case from X-Case, giving me a couple of spare U should I decide I want another rack-mount machine or two.

  • Public Statement on Neutrality of Free Software

    F-Droid won’t tolerate oppression or harassment against marginalized groups. Because of this, it won’t package nor distribute apps that promote any of these things. This includes that it won’t distribute an app that promotes the usage of previously mentioned website, by either its branding, its pre-filled instance domain or any other direct promotion. This also means F-Droid won’t allow oppression or harassment to happen at its communication channels, including its forum. In the past week, we failed to fulfill this goal on the forum, and we want to apologize for that.

  • An Indian research university has assembled 73 million journal articles (without permission) and is offering the archive for unfettered scientific text-mining

    The JNU Data Depot is a joint project between rogue archivist Carl Malamud (previously), bioinformatician Andrew Lynn, and a research team from New Delhi's Jawaharlal Nehru University: together, they have assembled 73 million journal articles from 1847 to the present day and put them into an airgapped respository that they're offering to noncommercial third parties who want to perform textual analysis on them to "pull out insights without actually reading the text."

    This text-mining process is already well-developed and has produced startling scientific insights, including "databases of genes and chemicals, map[s of] associations between proteins and diseases, and [automatically] generate[d] useful scientific hypotheses." But the hard limit of this kind of text mining is the paywalls that academic and scholarly publishers put around their archives, which both limit who can access the collections and what kinds of queries they can run against them.
