This author seriously needs to expand all of his TLIs (three-letter initialisms) the first time he uses them, as any writer worth his or her salt would do. There are those who may be interested in what he has to say, but can't follow because of assuming abbreviations.

Though I agree with you on expanding TLIs, if you have to have "ETL" defined for you, you probably won't get the "joke". And though this will come out more cynical than I intend, if you don't know the acronyms, then you probably won't be buying what Stitch Fix is selling. Filtering their funnel, maybe?

While possibly true, it's simply a courtesy to the reader to parenthetically define any acronym the first time it's used in a published piece of writing (of course this would not apply to internal emails, casual comments such as discussion forums here, etc.)

The original post may have been intended for a select audience that would be familiar with the context, so that author may be forgiven, but the person that submitted the post should have kept in mind the much wider audience here.

As a hardware engineer, ETL is a NRTL that competes with UL and CSA. Oh, excuse me, Thomas Edison's Electrical Testing Labs is a Nationally Recognized Testing Laboratory that competes with Underwriters Laboratories and the Canadian Standards Association.

Hm? Stitch Fix is selling clothes, not software. This is just their engineering blog.

TLA is the common abbreviation for what you call TLI, that is Three Letter Abbreviation.

The common abbreviation for a four letter abbreviation is ETLA. That is, Extended Three Letter Abbreviation.

ETL, DBA, API - aren't they all incredibly standard acronyms?

Not to me. I know what DBA and API are, but I've got no idea what ETL is.

Standard for you means that we live under rocks? Obviously if it's standard we must be clueless. Nice way of phrasing it.

100% agreed. I was clueless about ETL too. While the acronym itself may be old, people forget that this field is hip and sexy for maybe like last 3 years or so.

Google fixes your ignorance instantly. This TLI is common enough to assume.

It's a pretty common acronym in the field, actually.

There are many of us here who are not in the field.

Maybe in the data science field, but not in the tech field more generally. Probably doesn't help that the thread title didn't specify it was data science-related.

Might end up sounding like this: https://www.youtube.com/watch?v=BpMwZDfSLBk
