Hydra Incompatibility with Certain gdb* Versions

There is a known compatibility problem between Hydra and versions 7.2 and 7.3 of the GNU* Debugger (gdb*).  When running Hydra under one of these versions, Hydra will hang.

Please use a different version of gdb in order to run Hydra under gdb.

This has only been seen in Linux* at this time.

  • Tips and Tricks to Optimize Android Apps on x86

    Intel has a vested interest in helping developers provide Android applications that run well (or even best) on Intel architecture. While Intel is working at the community level - optimizing Dalvik Java, V8 engine, and Bionic C; contributing to the code base; and providing releases with both 32 bit and 64-bit Kernels for IA; they are also creating new tools to help  Android developers. Many of these focus on improving performance beyond that available with the default ARM translation layer for x86: libhoudini
