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.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
