If you're in trouble and cannot find an answer to a question which goes beyond Stack Overflow...
If you have a not-so-usual solution for your problems but need to justify it to your boss...
If you like to think on your own rather than blindly follow "common wisdom" and "profound truth"...
...then 'No Bugs' Hare on Soft.ware might be the right place for you.

MCUs are quite different from traditional-CPUs-we’re-dealing-with-most-of-the-time, and often require different handling.

Bringing Architecture of Operating Systems to XXI Century – Part II. Desirable Improvements

Quote: “low-end versions of the new OS should be lean enough to run on a ~$1 MCU (these days ~=4K RAM, 32K ROM)”
Another Quote: “last N minutes of the life of the production program before crashing, should be replayable on my development box.”

Journaled Flash Storage – Emulating EEPROM over Flash, ACID Transactions, and More. Part II – Existing Implementations by Atmel, SiLabs, TI, STM, and Microchip

Quote: “Whenever a developer is using something named ‘X Emulation over Y’, she may expect that a faithful emulation exhibits the same properties as original (non-emulated) X.”
Another Quote: “Unfortunately, as discussed in detail above, none of five implementations is a really faithful EEPROM emulation.”

Journaled Flash Storage – Emulating EEPROM over Flash, ACID Transactions, and More. Part I – Flash vs EEPROM

Quote: “You cannot erase single byte of Flash, but need to erase the whole page”
Another Quote: “First of all, we want to be sure that whatever-is-already-written to our persistent storage, stays there; this property is known as Durability.”

Modified Harvard Architecture: Clarifying Confusion

Abstract: Definition of “Modified Harvard” architecture is confusing and overbroad. Proposed alternatives are “Almost-Harvard” and “Almost-von-Neumann”
Quote: “One thing nobody realised for a while is that the system with the least possible amount of chargebacks is the system which rejects all transactions outright”
