Abstract: The disclosure provides systems for 3D printing. A 3D printer system includes one or more sources of actinic radiation characterized at least by a powered state and an unpowered state. A resin enclosure is transmissive to the actinic radiation. A temperature control system thermally communicates with the resin enclosure and maintains the resin enclosure at a predetermined sub-ambient chilled state. A control circuit is in electrical communication with the sources of actinic radiation and the temperature control system. The control circuit includes first non-transitory logic to switch the sources of actinic radiation to the powered state when one or more threshold criteria is satisfied including a requirement the temperature control system is in a predetermined state causing the resin enclosure to be below a temperature. A second non-transitory logic switches the sources of actinic radiation to the unpowered state when one or more threshold criteria is not satisfied.

Abstract: Vulnerabilities to physical memory, such as server dynamic random access memory (DRAM) with error correction code (ECC) capability, can be mitigated though the use of guard pages allocated in that physical memory. Physical memory pages can be mapped to virtual memory pages of a contiguous virtual address space. When an error such as a bit flip is detected in a physical memory page, the data from that physical memory page can be copied to a protected page, such as a guard page or page isolated from other sensitive data. Information such as an error correction code (ECC) can be used to determine and correct the erroneous bit. The mappings in a related page table can be updated such that the same virtual pages or addresses are then mapped to the guard page that now includes the relevant data.
