Abstract: Embodiments of the systems and methods disclosed herein includes a NAND flash memory having a boot volume. The boot volume can include a primary boot partition, a secondary boot partition, and a rootdisk partition. The primary boot partition can be configured to receive a kernel component of a file. The secondary boot partition can be configured to receive a copy of the kernel component of the file. The rootdisk partition can be configured to receive a root filesystem of the file.

Abstract: A method of reducing a concentration of hydrogen peroxide from wastewater includes diluting the wastewater with water having a lower concentration of hydrogen peroxide than the wastewater to produce a diluted wastewater, contacting the diluted wastewater with a dissolved iron compound at an acidic pH to form a partially treated wastewater having a lower concentration of hydrogen peroxide than the diluted wastewater, and precipitating iron solids from the partially treated wastewater by raising a pH of the partially treated wastewater to form a neutralized partially treated wastewater.

Abstract: A method is provided for authenticating two distinct objects using a single signature stored on one of the objects. On initiation of a hardware system a valid hash value can be generated based at least in part on a rootdisk file and a kernel can be modified to contain the valid hash value. On subsequent boots of the hardware system, the valid hash value stored within the kernel can be compared with a value of a potential rootdisk file and if the valid hash value and the rootdisk hash value match, the hardware system can proceed with the boot process.

Abstract: Various implementations described herein are directed to technologies for providing a software stack migration. A flash memory is provided. The flash memory includes a plurality of memory partitions. The plurality of memory partitions include at least two reserved memory partitions and a file system partition. A file system upgrade stored in one of the plurality of reserved memory partitions is provided. Partition sizes of the plurality of reserved memory partitions and the file system partition are changed in response to the provided file system upgrade.
