G+_Joe C. Hecht Posted June 20, 2014 Share Posted June 20, 2014 TWiT's Coding 101 - Episode 22 - Perl: Ifs, Thens, and Regular Expressions Episode 22 was a well thought out episode, presenting basic Perl concepts. The host's level of confidence was readily apparent in this episode, and the material was carefully rolled out like a set targeted bulletpoints, delivered with the tempo of a well timed Swiss watch, and presented in a clear, concise manner. Recommend. There were few shortcomings with this episode. The "shebang" line was notably missing in the host's examples, yet was included in the "Guru's" examples, and it's purpose has yet to be well explained. While this will not be a problem for Windows users, this may cause a few viewers using Mac machines to stumble a bit, while most Linux user's are probably well familiar with having to adjust the "shebang" line in a script file. The Guru (TWiT's Patrick Delahanty) presented code to explore regular expressions. The code could have been a little cleaner, and the overall explanation of "what a regular expression is" fell somewhat short of the complexity of the code presented. It would have been a very nice touch had the guru issued "clear" commands between run's of the exercises, instead of allowing the output from differing runs to jam together on the screen. Overall, the guru might want to put a bit more planning into his presentation, so that looks at least as clean and crisp as the host's code. The Padre did a great job of explaining the use of $variables that are embedded into output statements. One could argue that also presenting the difference of using single quotes and double quotes (and embedding dollar signs) into expressions might have been a very timely concept. A pointer to the first Perl episode detailing installation might have helpful to any new viewers coming in the door. Overall, I have to say the hosts seemed very focused in delivering a lesson that was very well planned. Kudos! Joe C.

G+_Patrick Delahanty Posted July 1, 2014 Share Posted July 1, 2014 I was pretty sure that we had covered what the "shebang" line was for in the first episode. If not, I apologize. Link to comment Share on other sites More sharing options...
