Firebird 3 by default in LibreOffice 5.4

Lots of missing features & big bugs were fixed recently .
All of the blockers that were initially mentioned on tracking bug are now fixed.

Lionel mentioned that he added a few more blockers that needs to be fixed until Firebird will be switched by default :
I went over
https://bugs.documentfoundation.org/buglist.cgi?quicksearch=firebird
and added a few open bugs to the blocker bug
https://bugs.documentfoundation.org/51780
based on their description (and NEW instead of UNCONFIRMED status)
only, without reading the bug log in great detail.
Tamás Bunth (Wastack) agreed that 6 months time frame is more than enough to fix bugs that will appear
I agree, it would be reasonable to wait a half year. Until that we can
fix the already found and the upcoming bugs, solve the backward
incompatibility. Even if those can be solved quickly we can upgrade to
the c++ API. 
Another issue is importing old hsqldb databases without java installed

It requires making a read-only parser for the HSQLDB "cached" table
data format in another language than Java. Most definitely possible,
the format may even be better documented than "read the source code".


Service for migrating Firebird 2.5 format to Firebird 3.0

On Libreoffice Devel there is a thread about migration of the already created odb files with 2.5 databases inside (fdb) but also about the forward and backward compatibility of the Firebird backup archive (fbk).

Lionel added notes about upgrading in the wiki :

People trade privacy for convenience or the other way round all the time. People that in this case favor convenience can use the hypothetical web service. People that favor privacy can follow the instructions at
https://wiki.documentfoundation.org/Development/Base/FirebirdSQL#Older_Firebird_databases(which the web service should point towards for information).While I'm not exactly lobbying for this web service, we are a volunteer-driven organisation and if Tamás feels like doing it, all the merrier.

Lionel Elie Mamane committed a patch related to this issue tdf#101789 : Firebird 3 - fails to build on OSX 10.11.x with clang

Lionel Elie Mamane committed a patch related to this issue tdf#101789 Firebird 3 - fails to build on OSX 10.11.x with clang.

It has been pushed to "master": tdf#101789 work around DYLD_LIBRARY_PATH limitations on newer MacOS X.

An alternative fix has been in place ever since Stephan Bergmann commit " Allow external/firebird to be built with a custom SHELL under Mac OS X 10.11".

Bunth Tamás commited a few patches related to Firebird driver

Tamás committed a patch related to tdf#74172 issue.
Ensure prepared while setting numeric
It has been pushed to "master":
It will be available in 5.3.0. The patch should be included in the daily builds available at http://dev-builds.libreoffice.org/daily/ in the next 24-48 hours.
More information about daily builds can be found at: http://wiki.documentfoundation.org/Testing_Daily_Builds
Affected users are encouraged to test the fix and report feedback.

Another commit is just code refactoring : get table name from resultset simply. There is a much simpler way to access table name in ResultSetMetadata in Firebird sdbc.

Tensorflow and why i love it

I work for my paper for master degree (Artistic style Implementation with Tensor Flow) and i love Tensorflow



Here are a few reasons why : It's python also i can use it quite easily with my gpus (gtx) also it's distributed across servers using gRPC


Tensor Flow has a clean, modular architecture with multiple frontends and execution platforms. Details are in the white paper.

Firebird 3.0 is released

Firebird Project is happy to announce general availability of Firebird 3.0 — the latest major release of the Firebird relational database.

The primary goals for Firebird 3.0 were to unify the server architecture and to improve support for SMP and multiple-core hardware platforms. Parallel objectives were to improve threading of engine processes and the options for sharing page cache across thread and connection boundaries.

Alongside these aims came new strategies to improve performance, query optimization, monitoring and scalability and to address the demand for more security options. A number of popular features were introduced into the SQL language, including the long-awaited support for the Boolean data type and the associated logical predications.

Read the Press Release for more information. Please refer to the Release Notes for the full list of changes. Binary kits for Windows and Linux on both 32-bit and 64-bit platforms are immediately available for download. MacOS X and other platforms will follow.
