Graph Type Rendering Update 3

Sven

Just another little update, the 3rd, see first update and the second one for progress.
Basically one bug within the TypecastRenderer has been fixed, transforming the Glyph into our OutlineShape. Furthermore it may produce Java code to be pasted in a test class to test remaining issues. Continue reading “Graph Type Rendering Update 3” →

Graph Type Rendering Update 1

Sven

After releasing JogAmp 2.4.0 (see feature/buglist), it was time to tackle an outstanding issue once again: Type Rendering. Motivation was born again by finding the most interesting feature to use Java with JOGL on Desktop, Mobile and Embedded Devices. At least for my taste, I identified this to be Graph UI,  an immersive UI within the 3D scene including text and UI objects and user interaction. Continue reading “Graph Type Rendering Update 1” →

What is Direct-BT? Where is JogAmp 2.4.0?

What is Direct-BT?

I happily joined Xerxes’s call to enhance the
Bluetooth experience on embedded GNU/Linux for Zafena.

This ended up in a new Bluetooth LE (almost done) and BREDR (in progress)
C++-11 implementation named Direct-BT.

It exposes a modern Java binding to the refactored original TinyB. Continue reading “What is Direct-BT? Where is JogAmp 2.4.0?” →

Resurrecting a dying Species? Bring back Java™ to the Browser?

Sven

While I was doing the admin work for the next JogAmp release 2.4.0 I added some old video teaser supporting the point of enabling high performance hardware accelerated features to anything Java™’ish for any platforms.

It rang some belts that all these demos were easily and interactive launched used Applets within the browser.
Sadly today, browser don’t support such plugin’s anymore, which enabled simplified launching of Java™ Applet’s and its seamless integration into the web page.

I well remember the debates back then, about bloated browsers and security issues. But what do we have today? Bigger (or bloated) browsers containing the VM implementation itself, only that this time it is not Java™ but a JavaScript VM. Not a big qualitative change, but a restriction to choice, IMHO. This move only disabled third parties enabling their content via the browser interface. Almost sounds like the old Microsoft and Firefox browser wars, only that this time all browser vendor are aligned and believe to be the good guys now 😉
Most notable for me is that the security issues has not changed here at all. Continue reading “Resurrecting a dying Species? Bring back Java™ to the Browser?” →

Cross Compilation to Arm64 for OpenJDK, JogAmp on GNU/Linux, iOS, ..

Sven

Finally pushed our crosstool-ng-projects configuration to our SCM repositories and published the latest signed & hashed binaries here.

Changes to the last April toolchain builds are multiple:

  • Updating crosstool-ng to latest release 1.24.0
  • Aligning configuration with Debian 10 (Buster):
    • glibc 2.28
    • binutils 2.31.1
    • gcc 8.3.0 (unchanged)
  • Using 4-tuple symbolic links to 3-tuple, dropping vendor. This allows drop-in usage for OpenJDK cross-compilation via –with-toolchain-path=/usr/local/x-tools/aarch64-unknown-linux-gnu/bin

Debian 10 (Buster) ZFS Live Image Recipe

Sven

First of all KUDOS to Debian’s new release this month, Debian 10 (Buster).

Notable to me is the effort for reproducible binaries, which aligns with my security Source Certification Contract (SCC) goals of Are You Who You Say You Are? Trust the Source, User.
Debian’s Buster release PR accordingly:

Thanks to the Reproducible Builds project, over 91% of the source packages included in Debian 10 will build bit-for-bit identical binary packages. This is an important verification feature which protects users against malicious attempts to tamper with compilers and build networks. Future Debian releases will include tools and metadata so that end-users can validate the provenance of packages within the archive.
