If you are just getting started with Redis or simply want to explore it a bit, Simon Willison’s tutorial is a good place to start.

Try Redis – Try Topic Maps?
Try Redis is a clever introduction to Redis.
I recommend it to you as an introduction to Redis and NoSQL in general.
It also makes me wonder if it would be possible to create a similar resource for topic maps?
Granting that it would have to make prior choices about subject matter, data sets, etc. but still, it could be an effective marketing tool for topic maps.
I suspect so even if the range of choices to be made to effect merging were limited.
If I were a left-wing one political blogger in the US I would create a topic map that includes donations to Republican PACs and white collar crime convictions by family members.
Or for the right-wing, a mapping between the provisions of ObamaCare and various specific groups and agencies.
Such that users could choose additional information and it shows up in some visually pleasing way to make the case that the user already thinks is true.
Will have to give this some thought in terms of a framework with a smallish number of framework topics and the ability to quickly add in additional topics for a particular demonstration.
Such that it would be possible to quickly create a topic map demo for some breaking news story.
Could provide useful additional content but the main purpose being a demonstration of the technology.
Useful content is fairly rare so no need to tax a topic map demo with always providing useful content. Sometimes, content is simply content. 😉

Redis Command Page – Topic Map Improvements?
Via Alex Popescu Redis: One Page Command References, an alternative to the Redis command page with Redis One Page command listing.
Take a look at both and then come back to this post.
Do you notice anything odd about the command information from Redis? Redis command page
While I appreciate the Time complexity information, that seems like a mis-nomer for most of the information present. The content is mostly an explanation of the command.
One reason I mention it is that I am thinking a topic map of the commands could certainly treat time complexity as a subject and therefore present all commands of a given time complexity. That could be useful in terms of planning a series of commands.
Another subject would be the examples. How many of them are shared and by which commands?
Will have to push it back and forth this week to see what develops.
Interface suggestions? Occurs to me that the traditional Unix man page layout, albeit with enhanced information, such as “example -> occurs in -> here be all the commands where it occurs” could be text/hyperlink bound might be a useful one.
Just enough addition to a traditional interface to make the additional information from a topic map available.
(The traditional topic map interface qualifies for the “an ill-favoured thing sir, but mine own” comment. I think we can and should do better.)

Interview with Salvatore Sanfilippo on Redis – Podcast
Redis with Salvatore Sanfilippo Podcast from MyNoSQL by Alex Popescu.
Sanfilippo says that Redis is a key/value database to be sure but from another point of view, it is also specific values that have data models. (?A fifteen minutes introduction to Redis data types)
See the Redis homepage
Which reminds me of a post on the nature of keys that I have been meaning to finish. More on that topic soon.

Redis Under the Hood
Via Alexander Popescu’s MyNoSQL blog.
Compelling examination of how Redis works. Some the diagrams are look a lot like diagramming subjects and relationships between them.
Take a look and judge for yourself.
Suggests 1,002 uses for topic maps doesn’t it?
Anyway, if you want to get into the internals of Redis, either for the sheer discipline of it or because you think it may figure in your topic map future, here is a good place to start.

Cassandra vs MongoDB vs CouchDB vs Redis vs Riak vs HBase comparison – Post
Cassandra vs MongoDB vs CouchDB vs Redis vs Riak vs HBase comparison
Not enough detail for decision making but a useful overview nonetheless.
