I just finished the CS7210 Distributed Computing this Fall. Don’t be scared by the OMSCentral review, the course is wonderful. It does require amount of more time and effort than many other courses, but the schedule and workload have been modified from the Sprint semester which it was first offered, and it felt much more balanced now. For the last projects, it’s not hard to get it working under simple conditions; however, it’s really hard to get full credits with a fault-tolerant version, particularly for messages being delayed or duplicated, and servers being crushed and recouped.
I took the summer class CS6200 Graduate Introduction to Operating Systems, which is primarily geared towards students with non-CS background like me, and I found the course to be very informative.
This past spring I took the class CSE6220 Intro to High Performance Computing. Though the name says introductory, the content is pretty hard and the workload is heavy. However, the projects were quite fun. Since all projects were implemented with C, pointer manipulation is a must to master in order to achieve a good performance score. Recursion is heavily used too.
This post is the continued talk about the persistent storage for Nordic nRF52840. In part I we went over using the Flash Data Storage (FDS) library. In this part II, I’ll be discussing another import component, user information configuration registers (UICR).
There are mainly two ways for persistent storage of data in NRF52840: flash and UICR. I’ll be discussing the flash mainly in this part I, and UICR in part II.
Nordic has a good tutorial Bluetooth low energy Advertising, a beginner’s tutorial, and two guides of GAP advertising Part I and Part II. In this post, we will go through some of advertising features in details.
The nRF Serial Port Library is designed as a more sophisticated replacement for the app_uart module, as pointed out at the library’s page, there are many advantages of this module over app_uart:
Nordic provides good examples, but mostly independent from each other. To make a BLE UART service with DFU support, we’ll need to merge the two examples:
Noric provides detailed documentations of Bootloader and DFU modules
