When reading about how to get the most out of Azure Tables, they mention "Avoid scans for dominant queries" as part of their conclusion.
What does it mean by "dominant queries"?
I've seen it mentioned in a few other questions but I do not have enough reputation to comment on other's answers yet so am asking as new question. Feel free to give feedback on that rather than downvoting this question.
"dominant queries" - most frequently run queries
"Select the dominant queries and updates based on such criteria as high frequency of execution, high volume of data accessed, response time contraints, or explicit high priority. Remember this rule of thumb: Any process whose frequency of execution or data volume accessed is 10 times that of another process is considered to be dominant."

On Monday I have big SQL exam for a job. (Have zero idea what they'll give me but as their system is still early DB rebuild it'll probably ask Q's about referencing disparate tables/info.)
My Q is: Come Monday, if I get some proc statements I can't figure out/make sense of is THIS a good please to come ask a question about a SQL statement? (It will be time critical I suspect.) OR, is there another "quick question about a proc stmt" website that would be better?
(FYI: Most of the role is finance-centric and my central wheelhouse, but I will get a SQL exam and would like to hedge my bet - to get back employed PLEASE!)
THANKS TO ANY AND ALL!

These words seem to be widely used to naming variables.
What do these words stand for and why are they so frequently used?
By the way, what's the origins of them?
These two words are just placeholders in computer programs. Wikipedia https://en.wikipedia.org/wiki/Foobar seems have a good answer. There are several origin of foo:
A nonsense word in the 1930s comic Smokey Stover by Bill Holman due to having seen it on bottom of a jade Chinese figurine in Chinatown, San Francisco, meaning "good luck".
US Army WWII acronym FUBAR, "F-ed Up Beyond All Recognition", which also explains the origin of bar.
The use of foo in a programming context is generally credited to the Tech Model Railroad Club (TMRC) of MIT from circa 1960.
It comes from the term FUBAR, which again stands for Fucked Up Beyond All Repair/Recognition. More on it from Wikipedia, here https://en.wiktionary.org/wiki/FUBAR
They have been used to name entities such as variables, functions, and commands whose exact identity is unimportant and serve only to demonstrate a concept. The words themselves have no meaning in this usage. Foobar is sometimes used alone; foo, bar, and baz are sometimes used, when multiple entities are needed.

In ZMQ messaging library there is large number of patterns derived from a base "Pirate" pattern. To quote the documentation:
I like to call the Pirate patterns (you'll eventually get the joke, I
hope).
I have a pretty through understanding of the ZMQ architecture, having worked with it over a half dozen projects and couple of years. Despite this, and reading basically the entire guide, I don't get the joke.
Perhaps there isn't one, but I can't help the itch that I am missing something fairly obvious. Thanks.
From the docs:
reliable request-reply (RRR) patterns that I like to call the Pirate patterns
Pirates say 'arrrr!' like RRR, hence pirate patterns.

Are SQL Developers and SQL Programmers same people? I have basic knowledge about SQL and want to improve it. plz help me?
No, I disagree - if you read Mike Gunderloy's excellent book Coder to Developer you'll understand a developer is a coder - but also a lot more.
A coder (= programmer) typically only writes code (possibly including unit tests) and that's about it. He usually gets a clear spec or task from someone else. A coder/programmer is more or less only concerned with writing, testing, and verifying code - nothing more.
A developer is a much more encompassing job description - a developer also deals with putting things into perspective, breaking up tasks into chunks that a coder can work on, he spends his time thinking about deployment and a lot more. A developer needs to know a lot more in his daily job than a coder.
Mike's book is good ... but if your going for a job the two terms SQL Programmer <-> SQL Developer are pretty much interchangable.
It just depends on what the hiring manager feels like calling the position.

Okay, you don't need to be a guru, but if you happen to have a good working knowledge on SSIS and you used some tutorials around the web to get you there, then please share them. I have been trying to find some solid stuff (screencasts maybe), but I am having a hard time.
Any solid links would be appreciated and I will add them to this question in an aggregated format at the end. Thank you.
So far we have:
http://blogs.conchango.com/jamiethomson
http://sqlis.com
http://blogs.conchango.com/jamiethomson/ A very, very good place to start,
I would recommend en excellent series of articles by Marcin Policht
There are about 50 articles at the moment and each focuses on different aspect of the SSIS, they are pretty detailed and I found them to be an excellent source of information on the subject of SSIS
Another great resource besides Cochango (great blog btw!) is http://www.sqlis.com/
I also found these two books to be very helpful:
Microsoft SQL Server 2005 Integration Services
Expert SQL Server 2005 Integration Services
I read them in the order that they are listed above.
These links are mainly components, but they have good information resources also.
http://www.sqlbi.com/ - Some great SSIS components for data warehousing BI
http://www.konesans.com/products.aspx - Some more useful components
The current Jamie Thomson blog is located here, where he continues to write about ETL stuff:
