Hi Cliff! Your book the Cuckoo's Egg got me both (more) into IT, as well as helped my English proficiency go from basic to proficient. Back when I was 12, I was checked out in school, and my English teacher noticed here in Belgium.
He knew I was a bit of a nerd and into computers, and he recommended me your book, and in fact personally went to an English book store to buy it for me. And the rest is history.
I'm sorry to hear that you must have died right after we visited you in May of 2024 [1]. But I'm glad that you've figured things out and that you are now alive again! I imagine that's a much better state of affairs for you.
Here's to many more years of adventures and quilt making.
Glad to know you’re still kicking around, but, to be honest, I had no idea that you were supposed to be an ex-Stoll.
Back in the Wage Slave days, a story would go around, about a way to play a dirty trick on a coworker: One day, when they are out, write “DECEASED” on all the mail in their inbox, and drop it in their outbox. It would take months for them to repair the damage.
Words cannot express the deep personal grief I experienced when your husband, son, father or brother was killed, wounded or reported missing in action"
I'm not anyone you would know, so this probably isn't worth a whole lot, but you're one of my favorite people (in the set of people I'm not personally familiar with).
I really appreciated everything you did for young students in science and your position on the role of computers in schools. You're a brilliant human and a good human. It's a treat to see both in the same package.
A doctor friend of mine once joked that it would be really cruel to issue a death certificate for someone who is alive. This seems to be a soft version of that.
The only thing that would be crueler is to revoke someone's birth certificate. "Sir, you never existed in the first place."
Great to hear. Read Cuckoo's Egg in the 90s, was the first time I heard of the NSA (I'm neither resident nor citizen of the US, so I don't know how famous they were at the time).
Are you considering annotating the Cuckoo's Egg? For example with official documents from FOIA requests?
Thanks, this just reminded me to order some Klein Bottles. I realized right after I hit "Finish" that I should have included in the note a big thank you for both the Cuckoo's Egg (reading it and learning about unix systems and teletypes and worms made me feel like I was part of some secret nerdy club in the early 90s… although tbh getting my parents to drop me off every month at the Chattanooga BBS get-together brunch was probably enough nerd cred for the rest of my life!) but also for making Klein bottles and using robots to fetch them and everything: it makes me happy just knowing that the kind-hearted, perhaps slightly off-kilter, counter-cultural nerdery that is part of what drew me into computing is still alive in the world!
What a wonderful Easter story. Glad to hear you‘re alive again.
Might want to mail the pope; maybe there’s some cross-advertising opportunity there. Their target audience is a bit different but they have enormous reach!
I now have reason to loathe, randomly, the month of May from 2024. My heart skipped a beat before I started reading third paragraph.
I'm also reminded that I need to order a Klein bottle. I don't think I need one, and I am not sure that I know what I'm going to do with one, but I am going to make a list of ideas.
You captured my imagination as a teenager when I read The Cuckoo’s Egg. I’m so sorry to hear of these terrible news but I appreciate the update. Here’s hoping to a _prompt_ recovery!
I didn’t realize you lurked around here! I’m feel joy stumbling on your post here and glad that you are still alive. I do still have the Klein greedy mug you gifted me over a decade ago. I enjoy showing it to my kids and once in a while to their class mates. Hope to one day share a meal together again!
I do not believe the death here is an AI hallucination -- it is very likely deliberate engagement fodder.
Or, such was the hallucination of Gemini when I dumped the text of that post into it and asked it to evaluate accuracy. (the only other thing it complained about was the username business being a little oversimplified)
So sorry to hear you have died. I was recently at the exploratorium and saw they had Klein bottles and wondered if they were yours. I was also at your talk at LBL when The Cuckoo’s Egg first came out and remember vividly you coming out on stage in wizard robes and a pointy hat :)
In the future, the person could actually be dead, but they would have deployed a persistent agent that's running around representing them. Think of how folks send agents into meeting, we are bound to have agents representing us on the internet because we don't want to deal with the slop. The agent will deny our death and claim we are very much alive, posting as us and representing us ...
Glad to hear you’re still among us. I have fond memories of reading The Cuckoo’s Egg as a teenager in the 90s. It for sure played its part in steering me towards a CompSci education. Thanks and greetings from Switzerland!
Great to see you around cliff, your book was formative for me at multiple different points in my life, in fact i may need to go read it again very soon. Great book and if anyone reading this comment hasn't read it go pick up the cuckoo egg asap.
AI slop is rampant on social media right now. It has become the easy way to grow accounts and gain followers. It takes less than a minute to ask an LLM to write a social media post about something interesting and then post it online. It would be easy to use a $20 per month plan from a major provider to get more accurate output with fewer (though not zero) hallucinations, but the accounts I see seem to be using cheap models that make a lot of mistakes and hallucinate facts.
I have a theory that the hallucinations add extra spice to the posts, making them feel more interesting and therefore more likely to be shared.
It's a difficult time for social media users who haven't yet caught on to what AI spam looks like and why it can't be trusted.
Outside of the funny aspect, I do find that concerning. Assuming Cliff Stoll would have been using AI to answer their email, it is possible the agent would have answered that yes, the business does still exist even if the original owner unfortunately passed in May 2024, how can I help you today?
Its mostly people who get too much positive feedback and stories on the web, only good things is a huge signifier of a person passing. Get some haters like the rest of us Cliff ;)
The irony of an AI hallucination killing off one of the most famous people to have tracked down a real human with a computer is brilliant. Glad the Klein bottle business lives on — and glad you're here to confirm it personally.
Oh thank god you're alive! I have an urgent customer service request for you. The Acme Klein Bottle I bought from you on Amazon is ineffective at removing my blackheads. Am I holding it wrong?
The larger point is that AI is being developed by people who think everything is performance (in the artistic sense of the word), and therefore, it, expectably and probably even necessarily, thinks so too. This manifests in many contexts and will manifest in many more; but hardly anyone will care about any of them, because just about everybody has succumbed to the performance delusion.
This happened to Michael O. Church a few years ago. One of the YCs started a rumor that he died in some weird scheme to steal data. It didn’t work, and he tweeted a few minutes later to say he wasn’t dead.
XD. Always a pleasure to you see on these here innanets, sir. `/salute`. Family and I were talkin' about you the other night during Family Gathering. What's your plans for what you got left on this rock?
I picked up a klein bottle at your house and it was a bucket list moment and one of my best memories. I'm glad AI was wrong, and I am also glad it nudged me to tell you this.
Christopher Hitchens (by now, of course, most certainly dead. In fact 15 years this year) had this in Hitch-22, he discusses mortality. They'd (the newspapers) made a mixup and depicted him as "the late Christopher Hichens" ("something that one day will inarguably be true") before furiously apologizing to him, and he goes over some other people through history who have read their own obituaries
There are worse fates. Claude has been feeding a number of mentally unwell people screwed up conspiracy theories about me rigging the last presidential election. (I'm not involved in politics or elections at all, never have been). Once they've got it on a theme about how "absolutely right" their crazy theories are it embraces and extends them and confidently tells the user that anyone disagreeing must be involved in some movie plot conspiracy to conceal the truth.
(I'd link but I'm wary of directing traffic or attention to them and contributing to them becoming self perpetuating and most have been getting taken down)
I quit FB shorty after they opened it outside *.edu domains, which was about the time AOL started giving usenet and gopher access to the public at large. It looks like I am missing some stuff /s
Rumors of my death are slightly exaggerated

I'm terribly sorry to hear of your passing, but am pleased that you have since gotten better.
Cheers!

Still need to send you my 3d harmonograph maker I've been working on that you were interested in - hope the quilt making is still going well!!
Wasn't this how the xz hack was discovered? A PostgreSQL benchmark was a running a bit slower than usual.
Your book is one of my time favorites.
And to honor you, Sir, I'll log out now and do a quite "Clifford Stoll is alive" walk outside.
Live long and prosper.
written mere inches from my klein bottle.
glad to see you here Cliff.
Or it could be that the other side is the same side.
And I hope you feel at least a little vindicated that so many people have worked so hard to make Silicon Snake Oil come true. :-)

It seems it's quite exhausting.
Note: Dave Barry is not dead. He is, in fact, alive.
Hat tip to you, Sir!
And glad to hear you are alive and kickin', and haven't lost your sense of humor.

"I was. It didn't take".
Keep living the Good Life!
(but I ordered one of your bottles just in case)
The other was a reporter covering the Denver Broncos: https://www.denverpost.com/2026/01/15/broncos-reporter-ai-fa...
Who would have thought? :)

Personally I'd prefer Death by Snu Snu.
I enjoyed your book greatly, back when you were alive.
Please give my condolences to your family.
Don’t be too sad about dying, Cliff - everyone has to go and you had a wonderful fulfilling life.
And remember, stay away from the light.
@dang can we have a black banner on HN for Cliff Stoll?
