+# Remote Dictionary Server (redis)
+
+Q: What is the best way to learn redis?
+A: Read this: https://raw.githubusercontent.com/redis/redis/unstable/redis.conf
+
+Q: Are keys unique to each database?
+A: Yes. `SELECT <n>` switches the context to that database #.
+
+```bash
+モ telnet 127.0.0.1 6380
+Trying 127.0.0.1...
+Connected to localhost.
+Escape character is '^]'.
+KEYS *
+*0
+SELECT 0
++OK
+GET xlgmokha
+$-1
+SET xlgmokha "was here"
++OK
+GET xlgmokha
+$8
+was here
+SELECT 1
++OK
+GET xlgmokha
+$-1
+SET xlgmokha "dissappear"
++OK
+GET xlgmokha
+$10
+dissappear
+SELECT 0
++OK
+GET xlgmokha
+$8
+was here
+QUIT
++OK
+Connection closed by foreign host.
+```
+
+Q. What does the append only file format look like?
+
+```plaintext
+*2
+$6
+SELECT
+$1
+0
+*3
+$3
+SET
+$8
+xlgmokha
+$8
+was here
+*2
+$6
+SELECT
+$1
+1
+*3
+$3
+SET
+$8
+xlgmokha
+$10
+dissappear
+```
+
+Q: Is that it?
+A: Yup! What more do you want?
+
+Q: Do you like Redis?
+A: Yes, I appreciate how simple it is.
