Doug Hull was the founder and owner of this blog for 10 years. I talked about his contributions in my first post.
Find out what he is up to these days in his interview with John Kelly over on the MATLAB Community blog.

Here I continue with my analysis of the log files of a different server. I need to modify my map function to create some variables and strip some rows which I am not able to do during file reading.
Features covered in this video include:

datastore
mapreduce
regexp

I want to carryout the analysis I did in my previous post on another server. However, that server has a different log file format. So I decide to make a parameterizable function that can return a datastore for any server.

mapreduce

Here I’m using the MapReduce functionality in Parallel Processing Toolbox to process several hundred GBs of server logs from our web site. I want to be able to visualize the counts per minute of certain quantities and also filter the data to look for certain special requests to our website…. read more >>

Here I show how the new arithmetic expansion rules in release 16b can be used to answer a blog post comment question. See the great post by Loren on the subject.

Here I take the analysis I did in this post to group website crawl data by the hour, and incorporate it into another function that runs daily. I forgot to turn on my webcam for this one, so its just screencast video.

Here I add another data column to my table, which is the Levenshtein distance between the redirecting source and destination URLs. This turns out to take much longer than I expected to compute, so I try using parfor to speed it up.

Here I’m doing some pretty mundane everyday modifications to an existing script (code-along style). I need to add an additional data column to a table I’m creating. I don’t explain completely what the code is doing but hopefully you will get an idea of some everyday coding work.
The picture is… read more >>

Last week I used varfun on a datetime variable in a table to count rows by hour. One of my colleagues said I should take a look at retime which operates on timetables. Here I give it a try.

When I analyze our website, the testing system I use downloads all pages. It can take several hours as there are almost a million of them in the subset I look at. Sometimes it takes longer than usual and I’m not sure why. I want to start doing some analysis… read more >>
