IBM Leak: IBM's "Word Usage Council" hunts for engineering words to be offended by
"White Hat" & "Black Hat" and... "Yellow Zone" & "Brown Zone"?
April 14, 2024

Companies and organizations (such as Red Hat / IBM, Intel, and Microsoft) have spent the last few years pushing for the elimination of technical terms such as "Whitelist", "Master", and "Man-in-the-Middle".

What follows is a bit of an inside glance into some of the exact conversations, within IBM (thanks to brave whistleblowers), around replacing these words -- a company which has been a strong driver in the war on engineering language.

"Subtle Racist Views"

Some of those expressing concern about technical and engineering terms appear to have little or no experience in the broader Computer Science field.  Case in point, this curious post from someone who (according to Linked In) is a "Mainframe Application Engineer" who first learned of the words "White Hat" and "Black Hat":

"I wanted to share an example of the implicit bias in their training materials.  I don't believe this is IBM-specific.  This looks to be application security sector specific.  Clearly this reveals that there is not enough diversity or black representation in that field.  This is offensive and plays on the subtle racist views."

This is one example -- of oh-so-many -- where the mere existence of a color is declared racist by those within IBM.

What's interesting about this: Neither "White" nor "Black", in this usage, has anything to do with skin color or ethnicity.  It, literally, has to do with the color of cowboy hats.  

"Brown & Yellow Zones"?

Another, absolutely delightful, example is this message -- posted by a Software Development Manager -- who just found out about the words "brown zone" and "yellow zone":

"OK, I'm on a call and I'm hearing about security-related terms like 'brown zone' and 'yellow zone'' are those terms we should be concerned about?"

Note that the original poster simply heard the words for a color and -- despite not being able to think of a reason why they would be objectionable -- thought he should reach out to see if anyone else can help him find a way to find it obectionable.

The responses?  "Using colors as identifiers can be unclear epecially for people who are color blind" and "I can readily see them being problematic."

Do either of these colors have anything to do with skin color?  Nope.  Having colored "zones" within networking is pretty gosh darned common.  Because it makes visualizing things easy.  Case in point:

Unless, of course, the "Blue Zone" in that slide above is specifically being racist against Smurfs.

Side note: I can't be the only person who giggles when he hears the phrases "brown zone" and "yellow zone"... right?

The IBM "Word Usage Council"

Of course, all of these IBM internal conversations resulted in IBM officially banning a wide range of terms from all internal communication -- and from all products.

"To be consistent with the tech industry and to reflect IBM values, the IBM Style and Word Usage Council has prohibited the terms 'blacklist' and 'whitelist'.  Instead use the terms 'blocklist' and allowlist' in all new and changed content.  The term 'slave', which has been allowed only for products with a history of using it, will also now be prohibited."

Yes.  IBM has a "Word Usage Council" that decides which engineering terms programmers within the company are allowed to use.  They have their own "Ministry of Truth" for technical words.

Not a joke.

Of course, we all know this has spread far beyond IBM -- with several companies (including IBM and Red Hat) forming the "Inclusive Naming Initiative".  Specifically to find engineering words to ban.

The wildest part of all of this -- as far as The Lunduke Journal is concerned -- is the existence of a "Word Usage Council" which can decide what words -- engineering words -- employees are allowed to use.

Truly wild.

The futility of Ad-Blockers

Ads are filling the entirety of the Web -- websites, podcasts, YouTube videos, etc. -- at an increasing rate. Prices for those ad placements are plummeting. Consumers are desperate to use ad-blockers to make the web palatable. Google (and others) are desperate to break and block ad-blockers. All of which results in... more ads and lower pay for creators.

It's a fascinatingly annoying cycle. And there's only one viable way out of it.

openSUSE says "No Lunduke allowed!"

Those in power with openSUSE make it clear they will not allow me anywhere near anything related to the openSUSE project. Ever. For any reason.

Well, that settles that, then! Guess I won't be contributing to openSUSE! 🤣

79 Million Views in 6 Months for The Lunduke Journal

Welcome to February, all of you amazing nerds!

January was a fun month for The Lunduke Journal (thanks to all of you). For those interested in a little Inside Baseball, I’ve pulled together some stats and charts below.

The short version: Great month. Crazy news stories. Solid growth. Can’t complain!

Revamped Lifetime Wall

Oh! And the “Lifetime Subscriber Wall” is getting a “retro” facelift.

This is what the four Lifetime Walls currently look like:

 

Once that 4th Wall is filled (a little over 75% of the way there as of this morning), I’ll be introducing the new designs (for all the walls) along with the starting of Wall Number 5.

Each Wall now has its own, distinct look and theme. Very Retro Computer-y. You’re going to dig it.

To make that “Wall Number 5” get here as fast as possible, I’ve gone ahead an reinstated the “$89 Lifetime Subscriber” deal. But only until Wall Number 4 is full.

Want to be on the Wall? If you don’t have a Lifetime Subscription, grab one. If you already have one, email me (bryan at lunduke.com) to let me know how you want your name to be displayed.

Once Wall 4 is full, the Super-Mega-Ultra Discounted Lifetime Subscription goes back to regular price. And, the next day, the new Lifetime Wall design appears at the end of new shows.

At the current rate, I expect that to happen in the next couple days.

Stats for January, 2026

Now let’s look at the stats for January.

Can’t lie. I’m pleased.

  • 30 new shows (just shy of one new show every day)

  • 15.2 Million views (including podcast downloads)

  • 2,326 new subscribers

The most popular story of January, 2026:

Taking a high level view: This means that, in the last 6 months (Aug ‘25 - Jan ‘26), The Lunduke Journal has had:

  • 79.4 Million views

  • 21,694 new subscribers

Bonkers, right?

Here’s a chart of “views” for last 6 months:

The long-term trend continues to be solidly upward, with February (in the first 7 days, so far) currently tracking slightly ahead of January.

For those interested in the specific platforms: The Lunduke Journal is seeing the most growth on X and the Audio Podcast.

Here’s a combined subscriber chart for January (up 2,326 subscribers from the month prior):

Image
 

Wild. It is truly amazing to me how widely these stories are spreading nowadays.

Over 15 million. In one month.

These are numbers that most of the big, “Main Stream” Tech Journalists could only dream of.

The reach of The Lunduke Journal, thanks to all of you, is now wildly exceeding any other publication I have ever worked with.

Even though most “Main Stream” Tech Journalists are refusing to cover some of the biggest stories in Tech… those stories are still getting out there.

They are being seen. Far and wide.

Thanks to all of you.

$89 Lifetime Offer Ends at Midnight!

I’ll make this quick: The $89 Lifetime Subscription offer for The Lunduke Journal ends at midnight tonight (Saturday, January 31st).

Once the calendar reads “February” — poof — the deal is gone.

If you wanted to save 70% on a Lifetime Subscription, these are your final hours.

A huge thank you to everyone who has signed up during this crazy deal. We are this close to filling up the 4th Lifetime Subscriber Wall (there’s a possibility it might fill up in the next few hours).

Far beyond anything I was expecting. All of you are absolutely amazing. The Lunduke Journal would not be possible without you.

If you were on contemplating grabbing that Lifetime Sub, I’d jump on it right now. The price goes back up to normal ($300) in about 12 hours or so.

Get it while it’s cheap!

The End of the $89 Lifetime Sub is Nigh!

Quick reminder: The massive deal The Lunduke Journal has been running — 70%+ off Lifetime Subscriptions, 50% off all other subscriptions — ends after tomorrow (Saturday, January 31st).

Considering that, here are the steps I recommend:

  1. Grab the $89 Lifetime Subscription before it ends tomorrow night.

  2. High five yourself for saving money and supporting Indie Tech Journalism.

  3. Maybe… grab a donut?

That is all.
