comment What are the time and space complexities of Classify/Predict?
Good idea, will try tonight... Ive always found complexity hard to get a handle on in mma because there's a lot going on under the hood. I thought maybe a dev would know offhand which libraries mma uses for each type of classifier

I'm reading the pdf on the Bayesian Change Point detection in R, this is a great resource, thanks!

comment Detecting components in timeseries
Is there a way to flatten out the discontinuities at {517, 539, 596, 632} and at {2218, 2237, 2368, 2392, 2708, 2735} so that the graph looks more like @dr.belisarius's graph? And in general there many be many more plateaus not just the two means, but n means, will your approach work for that too?

Nice work, but I'm still wondering how to find the x points 1k and 2k where the boundaries are?

I was able to use your observation to write up a solution, thanks.

comment How can I encrypt/decrypt a directory?
You are missing the middle two steps, i.e. save the encrypted information to a standalone file, and then read that back in.

You're right, that's weird that it won't work with out that, hmm.

comment How can I encrypt/decrypt a directory?
Your answer only address a previous issue, but doesn't answer the question. If you can get the steps to encode and decode a local file/directory, then I can award you the points!

Also "AspectRatio -> 1/4" seems to break the sizing.

Ah yes, SetDirectory[StringTake[$LocalSymbolBase, 8 ;;]]; FileNames[] works

@PatrickStevens That is giving me a SetDirectory::cdir: Cannot set current directory to file:///Users/Library/Wolfram/Objects/LocalSymbols. >>

@PatrickStevens This isn't working for me: In[7]:= LocalSymbol["ab"] = 1 Out[7]= 1 In[8]:= FileNames[$LocalSymbolBase] Out[8]= {}

comment Aliases for keys?
With this approach, everytime I do a query I'll need to use MatchQ which is slow.

In[211]:= <|"Major" | "Maj" -> {0, 4, 7}|>["Major"] Out[211]= Missing["KeyAbsent", "Major"]

comment How to zip a folder?
Ah we are getting to the heart of the issue -> I don't think it replaces a shell, but the shell is a process that RunProcess and friends were made to work with. Am I misunderstanding something?
