Imagine a tech conference having no CFP, as they reach out to speakers directly. They successfully attract some of the most heavy hitter men speakers in tech, and 3 women speakers.

Now imagine my surprise that 2 of those women are FAKE profiles.

They do not exist.

Nada.
I contacted speakers I know about this.

They had no idea.

One of the fake women profiles is supposedly a core Ethereum contributor, and a staff engineer at Coinbase.

No such contributor, no one heard of her at Coinbase now or before.

Why do this?
Sad to say but going forward if you are invited to speak at a lesser-know conference: do your diligence… if other listed speakers actually exist?!

This is a paid online conference, large number of (paid) attendees, workshops sold out.

What a mess.
Just to be very clear this is about the organisers creating fake profiles.
To spell it out why this conference generated fake women speakers. Because the organizer wants big names and it probably seemed like an easy way to address their diversity concerns.

Incredibly lazy.
Which conference?

Well, where Anna Boyko, Staff engineer at Coinbase and Ethereum core contributor is a speaker.

Her. She doesn’t exist. Except as a listed speaker at a prominent online conference! Image
Or another Java conference by the exact same organizer where Microsoft MVP and WhatsApp senior engineer Alina Prokhoda is a featured speaker.

Would you know there is no such Microsoft MVP and Meta employee.

Speakers listed on these conference had no idea I talked with… Image
This conference doesn’t have a call for papers because they follow the “Hollywood principle” (that sounds made up btw)

But then do AI generated images, fake names and titles for some fake women speakers profiles… and I cannot fathom WHY.

Absolute laziness and dubious ethics. Image
If you bought tickets to DevTernity (“DevTernity”) on 7-8 Dec you’ve been duped with fake speaker Anna Boyle who is still on the website. A made up profile, AI image, no such staff eng at Coinbase.

And some other listed women speakers don’t actually talk

devternity.com
And if you are planning to buy tickets to JDKon 2024 (#1 international conference designed specifically for professional Java developers.) on 22-24 May 2024: save your money because Alina Prokhoda doesn’t exist either.

This conf:

Same organizer.dev.events/conferences/ta…
Anything organized by “Dev events” is by the same organizer who creates these fake women speakers (and has some in the past as well) for some mysterious reason.

All their conferences:



I would avoid like the plague with such dubious ethics.

Why?? dev.events
Image
What do you know - after being called out, the organizer is removing some fake women profiles.

Here’s the archived website. Fake Anna Boyle (staff eng at a Coinbase, core Ethereum contributor) was there for only 10 months, while most tickets were sold.

web.archive.org/web/2023110914…
DevTernity has had fake women speakers listed for years.

Here is fake Anna Boyle’s “colleague” fake Natalie Stadler claimed to be at Coinbase (no such person ever worked there ofc - I checked).

She “spoke” in 2022 there as well.

Just incredible.

web.archive.org/web/2021112802…
Image
And there’s no more conference website.

For now, that is. Image
The website had a public GitHub repo where you could see the full edit history that someone found and pointed to me.

You could see eg how fake Anna was added 10 months ago. Or how after being called out for what it is, the organizer removed fake women speaker profiles.
Image
Image
The organizer responded, claiming he tried so hard to get women speakers but it’s… too hard. For a paid (!) conference w a price of €789 / $870 per person.

Meanwhile others just… invite a variety of people, including so many women. They exist. If you actually care that is.
The conference website is up and fake Anna removed.

But fake Julia is still there. Listed every year as a speaker, never delivered a talk any year (and “dropped out” this year as well) @lizthegrey did some digging.

A fake catfishing profile, it seems.

linkedin.com/posts/efong_ge…
Image
@lizthegrey This is Julia’s Xing profile (basically LinkedIn for Germany). She is/was an architect at Uber Estonia?!

Uber never had no eng office in Estonia. No such person ever worked at Uber.

On LinkedIn, her profile used to have Microsoft in the past as well.

xing.com/profile/Julia_…
Image
@lizthegrey The organizer claims they 1x accidentally added a fake speaker to their conferences. But actually:

2021 & 2022: fake Natalie & Julia
2023: fake Anna, Alina & Julia

All listed as speakers. Never delivered a talk. Not removed from the site till this thread.

Once a mistake, sure.
@lizthegrey Several speakers cancelled, already let the organizer know they won’t present.

I don’t blame them for not wanting to endorse a conference with a history of catfishing with fake women speakers for years.

As fast as the organizer was to remove fake Anna, they are still listed.
@lizthegrey Conference page lists speakers who have cancelled. Several others have asked to be removed.

No one with a sense of integrity will want to be associated with such a conference. One where organisers created fake speakers for 3 years in a row and still deny there was a problem.
@lizthegrey Jetbrains no longer wanting to be associated with DevTernity or JDKonf. Pulled sponsorship and had their logo removed.

Again, show me another conference that has had advertised fake, non-existent speaker profiles for years.

Why would any brand want association with one.
@lizthegrey It’s not just DHH who’s never seen anything like this. None of us have.

A conference organizer inventing and promoting fake, non-existing speakers for years has no business in tech going forward.
@lizthegrey Speakers have been cancelling en masse and asking the organizer to disassociate them from DevTernity and JDKon. They are still on the site so are making it clear in public they have no further association.

Imagine duping such high profile folks. What was this organizer thinking.
@lizthegrey For years, this conference series (DevTernity, JDKon) has been duping speakers who care about diversity and nominate underrepresented speakers for non-diverse lineups.

Obviously on top of duping customers paying ~$800 per ticket for speakers who do not exist.
This thread started as fake speaker accounts at DevTernity and JDKon.

It ends with what is very likely a catfishing Instagram account operated for 5 years: Coding Unicorn. Growing it to 115K Insta followers to promote the conference.

Shameful.

@TimothyMaksim Oh wait you’re an AI generated image. Ok anon.
@AlexeyEccc @simekadam @lizthegrey And sure: some reviews might not be fake. But the only objectively verifiable review is from a fake account!

This goes back to: what can you possibly trust after that?

Perhaps all reviews are real, save for the one with the full name? Maybe. But then, why??
Published a summary, summarizing what I uncovered about the non-existent speakers.

Fun fact: the first fake speaker was added *the same day* as someone complained about the lack of women speakers, here, on Twitter, on 3 Aug 2021!

Coincidence?

I hate this site

The below blue checked account makes up completely fake stuff - that never happened - and it gets 2M+ views. No it didn't happen

People treat as fact, thanks to having a $8/month blue check

Fake news (often written by AI) spreads on this site like wildfire Image
The account fwiw was created a month ago and seems to try to generate outrage to get followers + ad revenue

The post is pretty much all AI generated fwiw

But it plays to the FOMO narrative of AI layoffs, and capitalizes on it. Just sad to see it spread

This account posts 10x posts like this to try and go viral, and finally did with this Amazon one

Notice the 2,847 layoffs he claimed?

2 days ago it was 2,847 applications for a role lol

This is clearly AI + shitposting and people are eating it up… while it causes anxiety Image

Eh. I just don’t buy this because I actually understand specific examples all too well:

1. It paints a picture of DoorDash disrupted by vibe coded alternatives. Dude. DoorDash / Uber moat is NOT software!! It’s real-world physical logistics. AI cannot disrupt DD…

2. (cont’d)
2. The example of AI agents disrupting travel agents because AI agents can find cheaper travel deals than what travel agents offer. Also BS!!

I worked at Skyscanner (massive airline + hotel + car rental aggregator.) Travel agents have the most of offering the cheapest tickets / packages already!! Due to their deep integration, social deals.

In a world where AI agents find the cheapest deals: travel agents win, airlines get slightly less direct business!! AI agents go to Skyscanner, find cheapest deal from a travel agent, buy it!!

Then if you made a mistake you have no option to change it lol
So now the examples from two industries I know pretty well thanks to having worked there / been involved in them (travel agents + ridesharing/food delivery) read well but are just BS at the fundamental level… other parts I don’t know well read well…. but what are the chances it’s BS at its core?

We’re entering the age of AI slop that people believe en masse.

This post is 100% fake and probably AI generated. All made up. Yet massive number of upvotes, views and shares.

Journalist @CaseyNewton got in touch with the “whistleblower.” The guy faked all “evidence” with AI… Image
The Reddit thread: reddit.com/r/confession/c…

Casey’s interaction with the “whistleblower” where he gradually realizes all “evidence” is AI-generated, designed to fool even journalists… then he confronts the faker. Worth the read

platformer.news/fake-uber-eats… Image
We’re entering a time when it’s harder to trust anything online: and surely more people will try to fool journalists with AI-generated “evidence.” In some cases, they will succeed, especially at publications chasing headlines and not doing proper investigation / reporting!

For the last ~20 years, I did most of my coding inside an IDE - the last ~15 with increasingly good autocomplete.

Which is why it’s so weird that I barely opened an IDE the last two weeks, even as I pushed lots of code. I use the CLI, the web and my phone (!!) to prompt code
When I just started out developing I remember being so so so full of ideas that I was coding in my head and wished I could have done programming while commuting / on the bus. With eg a phone. But it was impossible, ofc.

Now it’s possible!! A massive change
I feel we’re in the middle of the biggest dev tooling change happening across the industry - and it’s happening over a few short months. And rapidly spreading everywhere.

Amusing: Google does not allow its devs to use its newly launched IDE, Antigravity, for development.

They can only use an internal version called Jetski: also built by the Antigravity team, with Google-speicfic features (eg monorepo support, docs search etc)

Using Antigravity is specifically disallowed and devs cannot sign up to it with a @google.com work address
The reason for this “ban” is, of course, Google’s “tech island” tech stack: Antigravity is simply not compatible with its monorepo, and not integrated to Google’s custom tooling.

Jetski has all of this - but it's a different product. A bit like Borg vs GCP (most of Google doesn't use GCP!)
Covered a lot more on Google’s unique culture (and how they have probably the most custom tech stack across Big Tech) in this deepdive: newsletter.pragmaticengineer.com/p/google

My personal anecdote on the impact of AI (aka Claude Code + Cursor)

There was this tool I wanted to build that would have helped my business a little bit at @Pragmatic_Eng, but not enough to

1. Do it myself (would have taken ~days)
2. Hire someone (too much onboarding)

But...
... but then I gave it a go with Claude Code + Cursor open.

In 30 minutes, I had something promising. In an hour, I got it done, exactly how I wanted (this was an addition to my existing codebase.) In another hour, I moved it over to a new stack I've been wanting to play with!
... and now it's done, and I've onboarded the first company on to this feature.

Here's the thing without this AI tool, I don't think I would have EVER done it! Not worth it.

So I think AI tools will do this. People + companies doing stuff they wouldn't have, before!
