Redundancy in Command, Keys and Values

In “Command, Keys and Values”, the first two paragraphs both say almost the same thing. I assume a dejà vu wasn't intentional.

Also, in the title, maybe Commands should be plural?

Russian version

I have fork of your repository with translation into the russian language. Can you put link to it in your README ?

Thanks.

tightlist error

hi, when trying to make a PDF from a markdown file that includes a list, i get the following error.

! Undefined control sequence.
l.213   \tightlist

i have a fix for this, if you want to give me perms to submit a branch and make a pull request i'll submit it, or you can just add the following line to pdf-template.tex:

\def\tightlist{}

I added it to the % Listings section, and now my .md file compiles and the list is rendered properly.

can't make the pdf

When I generate the pdf of the cn version of this book, following error will occur:

markdown2pdf: /tmp/pandoc/redis.log: hGetContents: invalid argument (invalid UTF-8 byte sequence)

I am already search google and some documents, but i can't solve the problem. How should i do for it?

And i can use pandoc to generate the epub successfully.

Chapter 1 - Memory and Persistence: Typo?

In chapter 1, Memory and Persistence, first paragraph you write

" By default, Redis will save the database every 60 seconds if 1000 or more keys have changed all the way to 15 minutes if only a 9 keys has changed"

Did you mean

" By default, Redis will save the database every 60 seconds if 1000 or more keys have changed all the way to 15 minutes if only a key has changed"

or

" By default, Redis will save the database every 60 seconds if 1000 or more keys have changed all the way to 15 minutes if only 9 keys have changed"?

Redis download link points to 2.6.2 (no SCAN is available there!)

Please, fix the link to the last version:

Should rename keys to ids for consistency

Actually for this issue #32, there are two places need to be fixed in the book, and the commit 469405d just fixed one of them.

The keys in below code:

keys = redis.lrange('newusers', 0, 10)
redis.mget(*keys.map {|u| "users:#{u}"})

should be renamed for consistency. (as well a minor range issue: 10 to 9)

ids = redis.lrange('newusers', 0, 9)
redis.mget(*ids.map {|u| "users:#{u}"})

There is also a minor error in this sentence:

...anything you want sorted by an some integer...

(error) ERR Operation against a key holding the wrong kind of value

In the data structures chapter, you get us to create a couple of sets, friends:leto and friends:duncan. In the next section, you get us to add scores to the set items, using zadd friends:leto 100 ghanima etc. I get the following error, though:

(error) ERR Operation against a key holding the wrong kind of value

Are sets and sorted sets completely different data structures? I was able to get through the chapter by choosing a different name for the sorted lists (zadd sfriends etc.) and couldn't find anything online to support the assertion that sets and sorted sets are two distinct data types.

Should hash examples use JSON strings

Examples like set users:leto "{name: leto, planet: dune, likes: [spice]}" should have quotes surround the hash keys. As in other languages , it's hard to parse "{name: leto, planet: dune, likes: [spice]}" such kind of strings without quotes surround hash keys.
