I tried out Facebook Live this afternoon, doing a MATLAB code-along using problems from Cody. I went through the Cody Challenge problem set that is recommended for new Cody users.
Here is the video on Facebook:

In part 2 of this Cody problem you need to select the next departure from a train time table based on certain criteria. It does take me a few tries to return the answer in the format the problem wants.
Features covered in this code-along style video include:

timetable
datetime

I offered to help my colleague Josh to convert a bunch of video caption text files from one format called DFXP to another called WebVTT. The text files store lists of voice-over captions with start and ending timestamps plus language information. I used some of MATLAB’s string handling functions to… read more >>

I need to save multiple MATLAB tables into an Excel spreadsheet; one worksheet for each table. I want the worksheets to be formatted to be easily read. So I develop a function that will do this by starting with a template worksheet and replicating it many times.

Here I realize that an assumption I had with the contents of a MATLAB table was wrong, so I need to find a way to ensure it is true so that the rest of my code works. I do it by inserting some dummy rows.

Are my blog post titles getting out of hand? Too many levels of hierarchy?
This Cody problem introduces the newish timetable datatype which I don’t know much about. Let’s take a look and see how you can use it. I get hung-up on one aspect of the problem until the very… read more >>

Here I try the first problem again in the Release 2016b Features Challenge. This time I don’t use regular expressions (with regexp), but use a new function in release 2016b (which I was kind of supposed to do the first time).

If I find a defect on our website, I first look for other similar defects and then create a test that runs regularly to catch future occurrences. I recently noticed a video thumbnail was not the correct aspect ratio: it was 4:3 instead of 16:9, like the middle one in… read more >>

In this problem in the Release 2016b Features Challenge set on Cody, you just need to combine an array of first names with an array of last names to create an array of full names.
Features covered in this code-along style video include:

+ for strings

I did part 2 of the text manipulation set of problems in the Release 2016b Features Challenge but forgot to record it (Doh!). So here is part 3 where you need to insert text into a string. I like to find the strangest looking frame from the video to use… read more >>
