You can use this query to show the size of a table:
 
SELECT table_name AS "Table", 
round(((data_length + index_length) / 1024 / 1024), 2) "Size in MB" 
FROM information_schema.TABLES 
WHERE table_schema = "$DB_NAME"
 AND table_name = "$TABLE_NAME";
or this query to list the size of every table in the database, largest first:
 
SELECT table_name AS "Tables",

When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.

To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.

What to expect

Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.

B = before
A = after

grep -B [number of lines] -A [number of lines] [search string] [file]

If you want the same number of lines before and after you can use -C num.

grep -C [number of lines] [search string] [file]

# get the submodule initially
git submodule add ssh://bla submodule_dir
git submodule init

# time passes, submodule upstream is updated
# and you now want to update

# change to the submodule directory
cd submodule_dir
