The Alternative Dictionary of Web Design Terms

Webdesigner Depot runs “The Alternative Dictionary of Web Design Terms“.  It’s simple, yet pretty funny and accurate.  I liked all of it, but a few of my favorites are:

  • Agile: A development methodology that advocates self-organizing teams and flexibility, allowing startups to more efficiently realize they’re building something that no one wants.
  • Backlink: Before experimenting with dogs, Pavlov trained online marketers to salivate whenever he said “backlink”. It still works.
  • Code: The stuff they show on computer screens in the less-offensive Hollywood representations of hacking.
  • Comments (in Code): In-jokes and clever insights that only total nerds will ever see. One day, someone will achieve true enlightenment, and the secret will written down as a code comment, and lost to an obscure GitHub repository.
  • Navigation: The quickest and easiest way for a customer to get lost.
  • URL: U R Lost.

 

Extract, Transform, Load

I’ve been doing all kinds of data migrations and system integration for years now.  But only yesterday I’ve learned that there is a very specific term linked to the process.

In computing, extract, transform, and load (ETL) refers to a process in database usage and especially in data warehousing that:

  • Extracts data from outside sources
  • Transforms it to fit operational needs, which can include quality levels
  • Loads it into the end target (database, more specifically, operational data store, data mart, or data warehouse)

ETL systems commonly integrate data from multiple applications, typically developed and supported by different vendors or hosted on separate computer hardware. The disparate systems containing the original data are frequently managed and operated by different employees. For example a cost accounting system may combine data from payroll, sales and purchasing.

What the hell is a serial killer?

I’m watching TV series “The Bridge“, and in the 5th episode of the 1st season there was this great scene where two Mexican thugs are discussing what’s a serial killer.  The TV series are not a comedy by any means, and the whole scene is done with a straight face, but I think it’s one of the funniest things I’ve seen recently.

Water testing is not a term (for software testing)

I’ve been hearing the term “water testing” for one of the work projects that I am involved in.  The term is used to describe the stage of the project when it’s available on the production servers with live data, but open only to a subset of the users.  After searching around for a bit, I can’t find a reference to this term anywhere, except the water industry:

Water testing is a broad description for various procedures used to analyze water quality.

So that of course sent me on to the path of finding the correct term.  The closest by analogy that I heard of is “smoke testing“.

The plumbing industry started using the smoke test in 1875.

Later this usage seems to have been forgotten, leading some to believe the term originated in the electronics industry: “The phrase smoke test comes from [electronic] hardware testing. You plug in a new board and turn on the power. If you see smoke coming from the board, turn off the power. You don’t have to do any more testing.”

Specifically for software development and testing:

In computer programming and software testing, smoke testing is preliminary testing to reveal simple failures severe enough to reject a prospective software release. In this case, the smoke is metaphorical. A subset of test cases that cover the most important functionality of a component or system are selected and run, to ascertain if the most crucial functions of a program work correctly. For example, a smoke test may ask basic questions like “Does the program run?”, “Does it open a window?”, or “Does clicking the main button do anything?” The purpose is to determine whether the application is so badly broken that further testing is unnecessary. As the book “Lessons Learned in Software Testing”  puts it, “smoke tests broadly cover product features in a limited time … if key features don’t work or if key bugs haven’t yet been fixed, your team won’t waste further time installing or testing”.

Smoke testing performed on a particular build is also known as a build verification test.

A daily build and smoke test is among industry best practices.

This sounds very much like “sanity testing“:

sanity test or sanity check is a basic test to quickly evaluate whether a claim or the result of a calculation can possibly be true. It is a simple check to see if the produced material is rational (that the material’s creator was thinking rationally, applying sanity). The point of a sanity test is to rule out certain classes of obviously false results, not to catch every possible error. A rule-of-thumb may be checked to perform the test. The advantage of a sanity test, over performing a complete or rigorous test, is speed.

[…]

In computer science, a sanity test is a very brief run-through of the functionality of a computer program, system, calculation, or other analysis, to assure that part of the system or methodology works roughly as expected. This is often prior to a more exhaustive round of testing.

After reviewing all sorts of testing types, I think the correct term for our scenario is actually “beta testing“:

Beta testing comes after alpha testing and can be considered a form of external user acceptance testing. Versions of the software, known as beta versions, are released to a limited audience outside of the programming team. The software is released to groups of people so that further testing can ensure the product has few faults or bugs. Sometimes, beta versions are made available to the open public to increase the feedback field to a maximal number of future users.
