This paper describe a highly flexible and configurable replacement for std::allocator for use with node-based standard containers. One of the most attractive features of C++ is the Standard Template Library (STL). At the root of the STL is an incredibly rich set of containers. The STL provides default implementations for contiguous storage, lists, sets and maps. As is always the case, however, general solutions do not come without a price. The default implementations of std::allocator provided by STL implementations vary in complexity by the STL implementation from thin wrappers around new and delete to carefully built allocators running to thousands of lines of code. Pool allocators are an extremely efficient method for providing allocation services for objects of fixed size s. The basic strategy is to reserve a chunk of memory sufficient for storing N objects of size s all at once. A potentially more serious caveat is that, since the allocator uses nonstatic data, it is not technically standard compliant because the standard requires that allocators of the same type be equivalent. The StoragePolicy is the most interesting and challenging part of the allocator. It dictates how individual PoolChunks are stored in a BunchOfChunks. It is also responsible for actually releasing the memory allocated by BunchOfChunks. StoragePolicyBoundary is similar to StoragePolicySimple, but it does a bit of extra housekeeping to enforce a boundary between full and nonfull chunks. Each BunchOfChunks object has a GrowthPolicy member that is responsible for calculating the size of the next chunk to allocate.

The article discusses a research paper by computer engineering professor Rajesh Menon, published in September 3, 2018 issue of "Optic Express," which focused on an optics-free camera. Topics discussed include the algorithm created by Menon to use a glass as a lensless camera; the light emitting diode (LED) light board used by Menon on one side of the glass; and the potential use of this technology in future autonomous vehicles.

This article traces the history of programming from source to frameworks. The notion of dynamic linking, which long predates Window's Dynamic Link Library, now lets programs invoke common routines without including them in every program's executable file. Programs become nondeterministic on a grand scale, because they depend on Other People's Code that not only is not included in the executable file, but may differ from run to run. On the hardware side, classic small-scale embedded system design started with datasheets for single integrated circuits that were actually comprehensible to one person. Evaluation board code tends to be written for the very specific purpose of showing how the circuit works. Considerations of reliability, error handling, overall structure, and security tend to fall by the wayside even in ordinary projects, but particularly for sample code that is written very, very early in the chip's design stage. Early in 2005, a trio of researchers from Shandong and Princeton Universities announced, without giving the details, an attack on SHA-1 message digest algorithm. Dallas Semiconductor subsequently produced a white paper describing the effect of the attack on its high-security memory devices.
