CIA & FBI can neither confirm nor deny they know about these Operating Systems
Gentoo Linux, OpenBSD, and even Windows Vista are hush-hush.

After I published “The CIA invests in these Tech companies”, it was pointed out to me — by one of The Lunduke Journal Community members — that the CIA had rejected a Freedom of Information Act Request for documentation about the Plan 9 operating system.

Not joking. Here’s the rejection letter from the CIA:

The FOIA rejection letter from the CIA.

That’s right. When it comes to Plan 9 (an open source research OS originating at Bell Labs in the early 1990s), “the CIA can neither confirm nor deny the existence or nonexistence of records” about it.

The Lunduke Journal can neither confirm nor deny that this is a screenshot of Plan 9.

Which is pretty doggone funny. I’d like to imagine that Plan 9 is part of some complex spy program. Possibly involving Nazi’s. And space lasers.

But this got me thinking… What other Operating Systems can the CIA “neither confirm nor deny” knowing about?

Let’s find out!

Linux and the CIA / FBI

Well, according to the CIA, they know nothing at all about Gentoo Linux.

This isn’t even a “can not confirm nor deny” scenario… The CIA straight up says, without ambiguity, they’ve never even heard of Gentoo Linux. No memos, emails, letters or reports that even casually mention the existence of Gentoo Linux.

Harsh!

Same goes for Yggdrasil, one of the earliest Linux distributions (from back in 1992).  The government has never heard of Yggdrasil!

How about for Qubes OS (a security focused Linux distribution)? Turns out the FBI “can neither confirm nor deny” that one.

Same with TAILS — a desktop Linux system designed to be used for whistleblowers, journalists, and others who might need extreme privacy. We get a “Neither confirm nor deny” by the CIA.

This time, an appeal was filed… that appeal was… drum-roll please… rejected by the CIA (they’re sticking with the whole “neither confirm nor deny” thing).

But, here’s a crazy bit. The same FOIA request was sent to the FBI regarding TAILS… and the FBI accepted it! Took a little back and forth, but the FBI released at least some documentation showing they know what TAILS is.

As far as I am aware, this is the only Freedom of Information Act Request where a government agency has actually acknowledged the existence of Linux at all. Which is a little amusing.

Also interesting… While the FBI admits to knowledge of TAILS… they “refuse to confirm or deny the existence of” records that shows the FBI actually uses TAILS.

From the FBI’s response to the TAILS FOIA.

OK, FBI. Got it. You can neither confirm nor deny that you use TAILS. Wink, wink. Nudge, nudge. Say know more. Know what I mean, know what I mean.

BSD and the CIA / FBI

What about BSD? Well. It turns out that the FBI is willing to admit a little knowledge of OpenBSD. How much knowledge? One document.

A single, highly redacted, document detailing a time (in 2002) when the openbsd.org servers were hacked. In Canada.

That’s it, and that’s all. Otherwise the FBI claims to have no knowledge of this “OpenBSD” thingamajig.

The CIA, on the other hand, can — say it with me now! — “neither confirm nor deny” that they’ve ever heard of OpenBSD.

Riiiiiight.

Microsoft Windows and the NSA

What about Windows? Surely there’s some interesting stuff the CIA, FBI or other agencies know about Windows!

Well, as it turns out, there is only one publicly published FOIA request — that we know of at the moment — that asks about Windows. Specifically, it requests documents relating to the NSA’s evaluation of Windows Vista.

Seriously.

And, while the NSA admits they have documents about Windows Vista… they can’t let the public know what’s in those documents.

Because… obviously… Windows Vista is a national security issue. Or something.

On the hunt for more

I have yet to be able to find FOIA requests for MS-DOS, AmigaOS, NetBSD, BeOS, PalmOS, Ubuntu, or many others. But I shall not give up the quest!

Because this is just too much fun.

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! 🤣

Macs: The final frontier

Below is a joke e-mail I sent to my best friend, a total Trekker (he insists it's Trekker, not Trekkie, though I'm such a castles-&-magic nerd that idk the difference - but I wrote it for him so I tried to go the space-&-aliens nerd route; a fun writing exercise if nothing else). After the joke e-mail is my first impressions, in a separate section.

I thought I had explored the farthest corners of the known universe.  I enjoy visiting the Retro Quadrant, with its ancient civilizations still thriving.  Commodore, DOS, Atari, and so many others, all alive and well, despite the constant attacks by newer and more advanced life forms.  Despite not having been born there, I consider that to be my home.  Then there's my actual home, in the Linux system; I say "system" but it's really more like an asteroid belt than a solar system.  Debian, Arch, Xubuntu, Kali, and the list goes on and on and on.  So many moons, all revolving ...

Top 5 Tech Stories of 2025 (According to Lunduke Journal's Viewers)
Gay software, Leftist Activists destroying computing, attacks on privacy, & more. Plus: Lunduke Journal had 14.9 Million views in December alone.

What follows are the top 5 most viewed Tech News stories, published by The Lunduke Journal, during 2025.

Presented in descending order of views received, starting with the most viewed.

[Links are to Substack, but all stories are freely available on several platforms.]

  1. Installing Linux Software Just Got More... Gay [Nov 24, 2025]

  2. Linus Torvalds Tells Google Dev His “Garbage Code” Should “Get Bent” [Aug 10, 2025]

  3. Leftist Activists Demand Removal of Ruby on Rails Founder, DHH [Sep 26, 2025]

  4. Microsoft’s Goal: Replace “Every Line of C” with Rust by 2030? [Dec 26, 2025]

  5. Use Firefox? Mozilla Says it Can Use Your Data However it Wants. [Feb 27, 2025]

And, just for the sake of posterity, here are the next most viewed stories, 5 through 10.

  1. Wikipedia Made $184 Million in 2025, Spent $3.4 Million on Hosting [Dec 5, 2025]

  2. Cloudflare Rewrote Their Core in Rust, Then Half of the Internet Went Down [Nov 19]

  3. Ubuntu’s Rust GNU Utils Replacement 17x Slower & Buggy [Sep 16]

  4. GNOME Foundation Discusses Refusing Funds from Framework Computer [Oct 17, 2025]

  5. Python Says Discriminatory DEI Policies More Important Than $1.5 Million Dollars [Oct 28]

Of those 10 stories… 4 of them were not reported on by any other major Tech News outlets. And 3 of the other stories were first reported by The Lunduke Journal (and then picked up by other journalists).

That’s… wild.

Worth Pondering

We know that The Lunduke Journal gets more social media traction and views than any other “Mainstream” Tech Journalism outlets (including the ones which claim to have “millions” of followers).

While we don’t know the current exact viewership numbers of the other major Tech Journalists out there, based on all available numbers it would appear that these are among the most viewed Tech News stories from any publisher.

Period.

Which means that this list of “Top Tech News of 2025” is about as close to definitive as we’re likely to get.

While we’re at it, for the sake of massive transparency, here are detailed statistics for The Lunduke Journal for last month. (Something the other big Tech News outlets would be terrified to reveal.)

Lunduke Journal Stats for December

Here’s some Lunduke Journal stats for December, 2025:

  • 14.9 Million views (or listens) during the last month (December).

  • 151,224 free subscribers (not including audio podcast feeds).

  • 2,196 new free subscribers on the primary platforms.

  • 342 shows, in total, in 2025.

  • $0.00 (zero) taken from any corporation.

December is, typically, the most quiet month for Tech Journalism. Fewer big stories. Lots of people on vacation. “View” numbers are, almost always, significantly lower than a typical month.

Despite that, The Lunduke Journal had a pretty stellar month in December of 2025. Second biggest month of the year (only slightly behind the previous month, which set multiple records), clocking in at just shy of 15 million “views”.

I’ll take it.

 

Total Free Subscribers also saw pretty decent growth, considering it was December (“the quiet month”), of over 2,000 new subscribers. Now topping 150,000.

 

A huge thank you, as always, to the amazing subscribers to The Lunduke Journal.

None of this work would be possible without you.
