Oracle ha annunciato il rilascio di NoSQL Database 2.0, DBMS non relazionale

New and enhanced features in Oracle NoSQL Database 2.0 include:
  • Better Performance: enterprise-class elasticity with near linear scalability and under five millisecond latency enables users to dynamically grow a cluster as their data grows with no interruption in service. In recent performance tests, Oracle NoSQL Database 2.0 delivered more than a million YCSB operations per second on a 2.4 terabyte database on an 18-node commodity cluster setup. (1)
  • Automatic Rebalancing: dynamic management of compute and storage resources to maintain SLAs in response to increased demand and changing processing requirements;
  • Enhanced Manageability: a simple, easy to use web console to manage all aspects of deployment and monitoring, as well as document management and structured data management in one product;
  • New APIs: a new C API helps improve developer productivity, a new Large Object API supports efficient Large Object management, and new automatic serialization APIs simplify application development;
  • Tighter Integration with Oracle Database: Oracle Database users can view and query Oracle NoSQL Database records directly from SQL via External Tables, making NoSQL data immediately accessible and available for integrated analysis;
  • Improved Management & Monitoring Support: SNMP/JMX support enables integration with Oracle and third party management tools;
  • Improved Hadoop Integration: tighter integration with Hadoop through JSON object and schema evolution support for data storage and serialization using Avro.

Embarcadero ha introdotto in C++ Builder XE3 un compilatore a 64 per Windows (BCC64) che si va ad aggiungere al vecchio compilatore a 32 bit (BCC32) che è utilizzabile per Windows e Mac OS X, a differenza del nuovo compilatore da 64 bit che è disponibile solo per Windows e per processori Intel. In questo post sono illustrate alcune differenze tra i due compilatori.

Il nuovo compilatore supporta gli standard C++98, C++TR1, C++11, ANSI C, ISO C, C99, C11, ed usa la versione 5.3 del Dinkumware's Standard C and Standard C++ libraries, mentre il compilatore a 32 bit usa la versione 5.01. Inoltre il nuovo compilatore usa la versione 1.5 delle Boost C++ libraries. Il vecchio compilatore a 32 bit non supporta la versione 1.5 delle Boost C++ libraries, ma la versione 1.39, e non supporta parte dello standard C++11.

Some compiler and Windows differences to be aware of (most of the time the compiler and RTL will take care of things for you unless you have platform specific code):

  • 64-bit Windows Applications use the familiar Windows API
  • Windows API calls must be 64-bit versions.
  • Try blocks are supported in 64-bit Windows programs.
  • A 64-bit Windows application can use a 32-bit Windows type library (as some 64-bit MS Office applications do).
  • Cannot mix 32-bit and 64-bit code in the same process.
  • DLLs, components, libraries, and packages require that you compile or install separate 32-bit Windows (design-time) and 64-bit Windows (run-time) versions if you want to use the Form Designer.
    64-bit Windows is needed for OS extensions, shell extensions.
  • The size of LRESULT, WPARAM, and LPARAM all expand to 64 bits, so message handlers will have to be checked for inappropriate casts.

Rilasciata la versione beta di Fedora 16

This release of Fedora includes a variety of features both over and under the hood that show off the power and flexibility of the advancing state of free software. Examples include:

  • Cloud Updates. Fedora now includes a number of new and improved features to support cloud computing, includingHekaFS, a "cloud ready" version of GlusterFS, including additional auth*/crypto/multi-tenancy; pacemaker-cloud, application service high availability in a cloud environment; and IaaS implementations such as Aeolus andOpenStack.
  • Virtualization. Once again Fedora raises the bar on virtualization support, including expanded virtual network support, an improved Spice for managing virtual machines, restored Xen support, a new virtual machine lock manager, and improved ability to browse guest file systems.
  • System Boot. Fedora 16 introduces GRUB2, the long-awaited next-generation boot-loader for Linux. GRUB2 automatically recognizes other operating systems, supports LVM2 and LUKS partitions, and is more customizable than the previous version. In this release, only x86 systems with a BIOS uses GRUB2 by default. Work is ongoing for making GRUB2 the default for other architectures and systems.
  • Services Management. Fedora 15 introduced the Systemd services management program. This release features better integration of Systemd via conversion to native systemd services from legacy init scripts in many software components -- for desktop users, this means faster boot times; for system administrators it means more powerful management of services.
  • Desktop Updates. The two major desktop environments have been updated to the latest releases: KDE Software Compilation 4.7 and GNOME 3.1 development release. GNOME 3.2 is available in the updates testing repository, enabled by default in this release.
  • System Accounts. Fedora now standardizes on login.defs as authority for UID/GID space allocation, and has moved boundary between system and user accounts from 500 to 1000 to match conventions followed by several other Linux distributions. Upgrading from a existing release will not be affected by this change and you can use kickstart to override this change during installation if necessary.
  • Developer Improvements. Developers get many goodies with Verne, including updated Ada, Haskell and Perlenvironments, a new Python plugin for GCC and a number of new and improved APIs.

La lista completa delle nuove features è disponibile a questa pagina. Download della versione beta di Fedora 16 da questa pagina.

  • A comprehensive I/O interface for working with file systems that can access a wider array of file attributes and offer more information when errors occur. (JSR 203: NIO.2)
  • New networking and security features
