Android is Linux (and Java)

In case you did not know, Android 2.1, Éclair, runs on the 2.6.29 Linux kernel. However, the user space it is built atop Dalvik, a Google-designed custom JVM (Java virtual machine).

This is pretty interesting, when you think about it. The core of Android is the linux kernel, and the standard unix/linux shell exists and is easily accessible; however, user applications are Java-based.

I have read some news reports with some strong opinions about "pure Linux" or "pure Java" and issues with Android.

At The UNIX and Linux Forums, it has always been both our mission and policy to steer clear of any "religious wars" between the various flavors of unix and linux. We don't even permit windows-bashing here!

All operating systems are equally of interest here, so if you are like me and interested in Unix and Linux, you are also interested in Android, because Android is Linux.

Making all this more interesting, of course, are all the predictions that Android will be the dominate mobile phone OS in a few years. This means there will be millions of more Linux users on the planet!

Yea!

NAME
regulatory.bin, regulatory.db - The Linux wireless regulatory database Description regulatory.bin and regulatory.db are the files used by the Linux wireless subsystem to keep its regulatory database information. regulatory.bin is read by crda upon the Linux kernel's request for regulatory information for a specific ISO / IEC 3166 alpha2 country code. regulatory.db is a newer, extensible database format which (since Linux 4.15) is read by the kernel directly as a firmware file. The regulatory database is kept in a small binary format for size and code efficiency. The regulatory.bin file can be parsed and read in human format by using the regdbdump command. The regulatory database files should be updated upon regulatory changes or corrections. Upkeeping The regulatory database is maintained by the community as such you are encouraged to send any corrections or updates to the linux-wireless and wireless-regdb mailing lists: linux-wireless@vger.kernel.org and wireless-regdb@lists.infradead.org SEE ALSO
