Appreciate if you can spare some time to peruse this little experiment of mine to use Comics as a medium to explain computer science topics. This particular issue explains the protocols and internals of HDFS. I am eager to hear your opinions on the usefulness of this visual medium to teach complex protocols and algorithms. [My personal motivations: I have always found text descriptions to be too verbose as lot of effort is spent putting the concepts in proper time-space context (which can be easily avoided in a visual medium); sequence diagrams are unwieldy for non-trivial protocols, and they do not explain concepts; and finally, animations/videos happen "too fast" and do not offer self-paced learning experience.] All forms of criticisms, comments (and encouragements) welcome :) Thanks Maneesh
