WhatsApp Introduces Ads in Its App

nytimes.com/2025/06/16/technology/whatsapp-ads.html?unlocked_article_code=1.PU8.G1Jy.5fcLP_rl3lYC

Eli Tan and Mike Isaac, reporting for The New York Times:

On Monday, WhatsApp said it would start showing ads inside its app for the first time. The promotions will appear only in an area of the app called Updates, which is used by around 1.5 billion people a day. WhatsApp will collect some data on users to target the ads, such as location and the device’s default language, but it will not touch the contents of messages or whom users speak with. The company added that it had no plans to place ads in chats and personal messages.

(a) I’ve never once looked at the Updates tab in WhatsApp; (b) does anyone believe they’re not going to put ads in the other tabs sooner or later?

100% effective

Every time I get into an online conversation about prompt injection it's inevitable that someone will argue that a mitigation which works 99% of the time is still worthwhile because there's no such thing as a security fix that is 100% guaranteed to work. I don't think that's...

Exoplanet System

Sure, this exoplanet we discovered may seem hostile to life, but our calculations suggest it's actually in the accretion disc's habitable zone.

Quoting Paul Biggar

In conversation with our investors and the board, we believed that the best way forward was to shut down the company [Dark, Inc], as it was clear that an 8 year old product with no traction was not going to attract new investment. In our discussions, we agreed that continuity of the product [Darklang] was in the best interest of the users and the community (and of both founders and investors, who do not enjoy being blamed for shutting down tools they can no longer afford to run), and we agreed that this could best be achieved by selling it to the employees.

The lethal trifecta for AI agents: private data, untrusted content, and external communication

If you are a user of LLM systems that use tools (you can call them "AI agents" if you like) it is critically important that you understand the risk of combining tools with the following three characteristics. Failing to understand this can let an attacker steal your data. Th...

Solide Unterhaltung. Der Wald war cool, Max Giermann war cool. Der Tochter hat's gefallen. Wir haben im Kino zu viel Popcorn gefuttert.

Florian asks everyone to please add their email address to their RSS feeds. Because then, FeedCity lets you directly reply to any of that feed’s posts via email (it’s a simple mailto: link).

Of course, I want you to do this, too! It’s one of those many underutilised data from a feed that can be really useful.

One thing to note is, that FeedCity won’t show the email reply button publicly (in FeedCity, all feeds have a public page) – it’s only shown for logged in users (or “citizens” as I call them). Prevents any email harvesting bots from gathering those addresses from the site.

Quoting Joshua Barretto

I am a huge fan of Richard Feyman’s famous quote:

“What I cannot create, I do not understand”

I think it’s brilliant, and it remains true across many fields (if you’re willing to be a little creative with the definition of ‘create’). It is to this principle that I believe I owe everything I’m truly good at. Some will tell you should avoid reinventing the wheel, but they’re wrong: you should build your own wheel, because it’ll teach you more about how they work than reading a thousand books on them ever will.

DetailsPro

detailspro.app?utm_campaign=dfwwdc25

My thanks to DetailsPro for sponsoring last week at DF — including being a sponsor on The Talk Show Live From WWDC 2025. DetailsPro is a designer/developer tool that lets you design with SwiftUI anytime, anywhere — from iPhone, iPad, Vision Pro, and, of course, Mac.

With WWDC 2025’s introduction of Liquid Glass, Apple has introduced the biggest design overhaul since iOS 7. DetailsPro is ready for it, enabling you to prototype new and updated interfaces fast. You can build real SwiftUI layouts directly on your iPhone — no code needed. Export clean SwiftUI code straight to Xcode when you’re ready.

While everyone else is still thinking about how to adapt to the Liquid Glass era, you can already be building. DetailsPro is free to use, with pro features if you need them — via subscription, or a one-time purchase.

🎬 The Nice Guys

Movie poster for “The Nice Guys”.

Ha, nice! Had a great time with this last night. Maybe I was a little too tired to follow the fast-paced plot and its twists and turns at all stages. But regardless, this was really funny, had great action, great dialogue, and the two detectives were just perfect. I especially like Ryan Goslings acting. A movie I could easily enjoy multiple times.

🎬 A Clockwork Orange

Movie poster for “A Clockwork Orange”.

Wow, I haven't seen this in a long time. And I pretty much couldn't remember the second half. Enjoyed this a lot. The characters, the sets and the visuals in general, the soundtrack. The content is often questionable. It's partly gross, yet cheekily funny, but always entertaining.

The interesting thing to me when watching old classics like this, is how I discover how influential they have been. Or at least I think I do see those references in other movies. Anyway, I saw elements of Wes Anderson, Michael Haneke and Yorgos Lanthimos in there; and certainly forget a whole bunch of others.

Saw this at the Metropol, where the staff gave yet another lovely introduction to the film.
