Four panel screenshot of classic Simpsons episode where crowd is booing Mr burns. He asks Smithers “are they booing me?” Who says “uh no. They’re saying boo-urns, boo-urns”. Burns asks the crowd if they’re saying boo or boo urns. The crowd boos. Coleman says “I was saying boo urns”.
The Usher “watch this” meme
An image of the cat from "Stray" on a playstation branded image, but it says "PSPSPS" like a cat. It's a riff on the "would" repetition from the original post.
An image of the Yatsi TypeScript interpreter playground, showing correct output for some console.log functions and a fibonacci calculation function to demonstrate return values, arguments, and recursion.
A screen shot showing some TypeScript code that calls a function which calls console log. The source has the function body, and we see an expected output, with a status of "PASS" in the corner.
A picture of Inigo Montoya that says “Hello, my name is Inigo Montoya. Chain React tickets are on sale. Prepare to buy.”

A screenshot of Chivalry 2 stats showing a positive kill death ratio with 6831 kills to 6830 deaths among other stats like 15,889 batteries
A user opens a web site and a mac app next to each other. On the web site, they press a button to start a simulator and stream. The simulator begins streaming output to the website. On the mac app, they press to shut down the simulator. It shuts down and then the stream gets cleared on the website.
A graph showing eight lines: total outlays for a user based on premiums, deductibles, and copays for health insurance. The graph is quite complicated.
A screen recording where a user uploads an iOS app to a barebones web interface. Once it's done uploading, they click a button to install on a simulator. The web site triggers an install on a simulator running on their computer, which streams its output back to the web browser. The user then taps the app tile from inside the browser. The browser forwards that action to the simulator, which opens the app. The user then shows some of the UI for the Mac OS app managing the simulator.

A messy home office in the middle of being put together.
A sample Lox program with a closure is run inside Xcode and the correct value is printed.
A Lox interpreter in C is run with an invalid program (too many parameters to a function). It fails with a stack trace that identifies where the error was.

Tyler Williams stands in front of a slide with a Fairly Oddparents meme that reads "this is where I'd show you a cool custom workflow - if I had one". The slide text is hidden behind the speaker, who is gesticulating wildly with his hands. The content of the slide is mostly about how the original presentation was going to be about a custom EAS workflow, but Expo created a much better way to accomplish the task with a pre-packaged workflow, so the presentation had to be re-done, which is kind of funny when you think about it.
A screen recording of an if/else statement in Lox, being compiled in a Lox compiler through Xcode.
Screen recording of an Xcode window where the user presses play to run the program. In the bottom-right, they then type (1 + 3) * 4. The Lox REPL interprets the arithmetic, and spits out debugging information including the stack trace of the computation, along with the final result.
Michael Scott saying “PowerPoint” three times in the episode where he clearly did not do the PowerPoint training he was supposed to beforehand.

A poll organizer with an/pm slots
TWO pill organizers on a shelf. Also other decorations like a wedding photo, candle, dice
A screen recording of an iOS app on a simulator, next to a Cursor code editor. The app shows four items of text with different styles, including a counting timer. The author adds a new line of JavaScript code, which draws another Text on the screen, and the code re-evaluates (we can tell because the counter text resets to 0).
A man sets up a set of dominoes in increasing sizes. The smallest domino is the Shiba doge meme. The largest domino is captioned "No one know show to maintain the US Nuclear Arms Stockpile anymore".
Panel 1: "Hi! My name is Jason". Panel 2, second person: "Ah! Nice to meet, you Jason". Panel 3, the person is taking that name and trying to jam it into their brain, where there are already some squares in their cartoon head. A small rectangle says "friends", a small one says "family", and a much larger one is the Expo logo. The first person's name is squished going in, clearly not sinking in. Panel 4, second person: "Say Jarvis, wanna hear about building truly universal native apps with React ath run on Android, iOS, and the web?"

A twitter screenshot from @TkDodo - the first tweet says What's the scenario 😅? The benefit is that every time someone uses them, it might backfire later. There are mostly two usages: 1) Write data to local state / redux / zustand etc. This is a) an anti-pattern and b) will get out-of-sync as soon as you read data from cache only Second tweet says: 2) use it to display success / error notifications, which breaks as soon as you use the same hook in two components, because each component calls the callback ... You'll wind up with multiple notifications, which is unwanted Half a reply is cut off but it’s less relevant

An image of a cat that says "I wake up, there is a new Jira ticket" with repeating arrows around it. A play on the "I wake up, there is a new technological advancement" meme
A screenshot of a Sleeper fantasy football team. The team name is a classic SQL injection that would drop the players table in a vulnerable database. It’s funny.
Two astronauts face earth. There is a fake code editor overlayed on the planet. One astronaut is slightly forward and asking “wait it’s just a bunch of text files?” And the one behind has a gun to the first one’s head, captioned saying “always has been”
Grandpa Simpson quote about how things are always changing and it’ll happen to you
A screenshot of the Legend of Zelda, with a caption that says "It's Dangerous to Go Alone - Take this", and instead of a sword like in the original, it's an Expo logo, to express the poster's strong recommendation to build native apps with Expo.
