Easy to confuse these words. Especially if you hear them with the novice ear.
brazier - container for fire
brasserie - literally, a brewery in French, but in actuality, a more informal restaurant. Some put restaurant, then bistro and then brasserie and finally cafe...
brassiere - bra in French
Forvo makes it easy to learn the ways to pronounce these words too.

Tomcat should not be confused with the Apache web server
If it's been awhile since you've been in the Apache tool space you may have wrapped up Apache into Tomcat.
They're still a separate product offering and NOT bundled together. Wikipedia even mentions it here.
If you're looking for httpd.conf and configure files, those only are for the Apache web server, NOT in Tomcat...
I used the Apache server for a lot of Perl programs I wrote in the late 90s and early 00s; especially when I first started at Sun and had to maintain some legacy Perl scripts.
While I was an intern at Sun, Tomcat had been introduced by one of Sun's engineers and I began using it (in addition to JRun) for hosting JSP/Servlet applications.

Agile
There's a few tenets to agile programming/development.
- Customer satisfaction by rapid delivery of useful software
- Welcome changing requirements, even late in development
- Working software is delivered frequently (weeks rather than months)
- Working software is the principal measure of progress
- Sustainable development, able to maintain a constant pace
- Close, daily cooperation between businesspeople and developers
- Face-to-face conversation is the best form of communication (co-location)
- Projects are built around motivated individuals, who should be trusted
- Continuous attention to technical excellence and good design
- Simplicity
- Self-organizing teams
- Regular adaptation to changing circumstances
Maybe it should be made into a rhyme like, "Jack be nimble, Jack be quick...," just for easier memorization of some of the tenets.
That rhyme could be updated for agile methodologies!

Shenanigans
Love the word shenanigans.
Maybe it means questionable goings-on with the understanding that whatever is going on can be treated with levity, irony and good sense of humor.
Seems to be a more popular word in my vocabulary these days :)

Oracle SQLPlus versus SQL Server and MySQL
Tested creating tables with some scripts we have here. Testing was against: Oracle 10g, SQL Server 2005, and MySQL 5x.
Somehow Oracle is this least intuitive.
I need some links for next time:
Connecting to SQL Plus
SQL Plus FAQ
Deleting tables (called dropping in Oracle)
Creating and dropping sequences
Creating a Trigger
Using a *.sql script from within SQL Plus
Dropping a trigger
Seems a lot more complex than MySQL or SQL Plus

We're a bearer token company
It was mentioned in a meeting in my first week that we're a bearer token company. The more I learn about my job and the different aspects of our company, the more I realize how true it is.
I've used tokens in the past and they have many definitions. Just type define: token in Google search.
Tokens in computer software - and in our company - provide identity delegation. They can be proxies for you so you don't have to keep logging into different sites with the same username/password, which is the idea behind SSO (Single-Sign On).
A user logs in once and a token is then used in their place when they want to use a service that's outside of their initial domain where they logged in first. Ping Federate bears the brunt of creating the token and passing it between disparate domains, saving the expense. For example, a user would login to United Airlines to buy a round-trip ticket. That user would also need to rent a car so United would use our SSO Ping Federate solution to allow a token to be passed from United to Hertz so the user could rent a car and not have to login again when transfered to the Hertz rental site.
Since tokens are the basis of communication between our federated servers, they can be quite simple, from passing on basic user credentials, or the more complex, providing further information or attributes to a requesting service provider.
In the beginning I had a bit of confusion with some terms that really meant the same thing. Since a lot of terms overlap I'll just list them here.
We use SAML tokens. These are the same as SAML assertions (or to be exact, are enclosed within a SAML message), which are basically XML documents sent over the wire. Whether you use token, assertion, SAML message, SAML assertion, XML assertion, in many ways, they are all synonymous terms. They provide the mechanism to proxy for an initial sign-in and pass that sign-on to another domain. By passing on the initial sign-on we are forwarding assertions about the initial users credentials.
Assertions are also called claims. Since tokens contain assertions/claims, you can have simple claims that state who you are (basic authentication) to more extensive assertions/tokens/claims (see how I interchange them?) that also authenticate you and/or provide more attributes about who you are. It all depends on what you want an assertion/token to do and what is requested by the service you are trying to access.
This is the basis of what we do.

find and locate
I've been using Unix find on the command line for many years and it's certainly saved me some time trying to find files or strings within files.
Here's an example usage that I've liked to use:
find . -name "*.java" -exec grep -l "Boolean" {} \;
This will find all java files from the current directory down that contain the string Boolean and then list their paths.
For something a little more basic where I just need to search for file extension types I use something like this:
find . -name "*.properties" -print
But, one thing I never heard about until yesterday was the locate command.
Locate uses indexed search results and was helpful when I was trying to find some JAR files in a local repository.
Basically it takes find and cron together, run at scheduled intervals, to index the local filesystem. Then when you use locate, it will use that index to quickly give back results, that might have taken long with just the find command.
