    1. CODepends what you're caching. If the information cached is private to a user, a hash collision could mean leaking private data (which I would call an earth shattering bug). Granted there are hashes that make hash collision probability effectively nil, but crc32 isn't one of them. It only takes slightly over 77000 values for the odds of a hash collision to be 1 in 2 (http://preshing.com/20110504/hash-collision-probabilities). Using a better hash function for the key helps, but every hash table implementation I know of accounts for collisions. It's not hard; just store and check the key.

    2. COI thought about this myself. I just always wondered if hashing to md5 was somehow reducing the security. Another way I thought of is that you could have an indicator tied to the account which indicates if the password is old or new. If new, hash to md5 then bcrypt. If new, just bcrypt. This, would allow you to convert the existing database completely so you aren't waiting on users to convert their old passwords.

    3. COThis should be the accepted answer. It's precisely what the error message is referring to. In my case when I cloned I had used a FQDN, but on my new machine I had only logged in using the short local domain name. I had to login via putty or plink as the FQDN to cache the key for the host name on the origin. It can help to cross check the hostname being used as the remote using "git remote -v".

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
