How to install Oracle Java 11 long-term support on Ubuntu

   Java 11 has arrived. The new release is the first planned appearance of Oracle's long-term support (LTS) releases, although Oracle has also grandfathered in Java 8 as an LTS release to help bridge the gap between the old release model and the new approach



Java 11 Changelog
  • Standardize the incubated HTTP Client API introduced in JDK 9, via JEP 110, and updated in JDK 10
  • New Collection.toArray(IntFunction) Default Method
  • The locale data based on the Unicode Consortium's CLDR (Common Locale Data Registry) has been updated for JDK 11.
  • Lazy Allocation of Compiler Threads
  • ZGC (Experimental): a brand-new garbage collector designed for sub-10ms pause times (even on large heaps) with an aim of no more than a 15% performance penalty.
  • Epsilon GC is the new experimental no-op garbage collector. Epsilon GC only handles memory allocation, and does not implement any memory reclamation mechanism. It is useful for performance testing, to contrast costs/benefits of other GCs.

How to Install GScan2PDF 2.2.0 release on Ubuntu 18.04

    gscan2pdf is a GUI to ease the process of producing PDFs or DjVus from scanned documents. You scan one or several pages in with File/Scan, and create a PDF of selected pages with File/Save PDF. At maturity, the GUI will have similar features to that of the Windows Imaging program, but with the express objective of writing a PDF, including metadata. Scanning is handled with SANE via scanimage. PDF conversion is done by libtiff. Perl is used for portability and ease of programming, with gtk2-perl for the GUI. This should therefore work more or less out of the box on any system with gtk2-perl, scanimage, and libtiff.


GScan2PDF 2.2.0 Changelog: 

  • Check validity of device blacklist regex when applying preferences
  • Modify preference “Force new scan job between pages” to only take effect when scanning from flatbed.
  • Fixed crash switching frontend option in Edit/Preferences between libimage-sane-perl and scanimage.
  • Fixed visibility of scan widgets when switching from libimage-sane-perl to scanimage.
  • Collect all warning and error messages in one dialog.
