![Most people think touchscreens sense pressure or heat.
But the real answer of what is technically going on… is way more interesting.
Your phone uses what’s called a capacitive touchscreen.
Under the glass is a hidden grid of transparent electrodes that creates an invisible electric field.
So here’s the big question: how does your finger trigger it?
Because your body conducts electricity, your finger changes the local capacitance basically how much charge that spot can hold.
The system measures that disturbance instantly and knows exactly where you touched.
That’s why your finger works, but a pen or most gloves don’t they’re not conductive.
And it’s also how multitouch works: the grid can detect multiple changes at the same time, which is why pinch-to-zoom feels effortless.
Older phones sometimes used resistive touchscreens that relied on pressure, but they were slower, less precise, and couldn’t do multitouch.
So every tap, scroll, and pinch isn’t pressure or heat… it’s your body becoming part of an electrical circuit.

![That’s a wrap on this year’s Meta Connect and honestly, what an incredible few days. I don’t even know where to begin.
✨ First, the people. The Meta team is hands down the most supportive, creative group I’ve ever met. Beyond Meta Connect itself, they’ve been cheering me on through my entire time as a newly working mom and now even supporting me as I travel with baby to San Francisco. The thought and care they put into every detail means the world to me.
✨ Then, the creators. Being in the same room with so much talent and energy is inspiring. Every single person brought something unique… whether creativity, business savvy, or both and it was incredible to be part of it.
✨ And of course, the tech. Watching Mark do live demos made the whole experience feel real and raw. I got to try the new Meta Ray-Ban display glasses which I was blown away with how crisp the display was both indoors and outdoors. I honestly couldn’t believe this tech is already here. The Neural Band? That’s another level altogether… deep dive video coming soon.
On a personal note: sitting here now on the patio, typing this with my 3.5-month-old son and my mom who came along to support me, I just feel so grateful. This season of life means I’m more selective about which events I attend and Meta Connect was #1 on my list for a reason.
And a quick thank you to the theparkjames team, who were absolute stars in making our stay as a first-time traveling mom so smooth.
Here’s to next year’s Meta Connect and in just a few weeks, picking up those Ray-Ban Meta display glasses!]()

![Who needs a phone when you can use these meta Ray-Ban display glasses?
I tried them out today and honestly… I was blown away.
The display was crystal clear whether I was inside or standing in bright sunlight. And the EMG band? Was wild. It picks up tiny movements in your fingers so you can control the glasses without waving your hands around. It felt natural.
What impressed me most is how all this tech fits into something that actually looks and feels like normal glasses. They’re lightweight, not bulky at all.
Can’t wait until these officially drop I’m definitely going to be getting a pair.

![Your plane isn’t connected to the internet the way you think… it actually calls space first.
Have you ever asked yourself how a plane even has Wi-Fi up there at 35,000 feet?
Here’s the surprising part: the plane isn’t connecting straight to the internet. Instead, it beams your data to a satellite which could be 36,000 km away in geostationary orbit, or just a few hundred kilometers up in low-Earth orbit. The satellite then bounces it back down to a ground
station connected to the web.
But wait wouldn’t that round trip make it really slow?
Exactly. With those faraway satellites, signals can take half a second just to go up and back.
That’s why airplane Wi-Fi used to feel so laggy. Newer systems fix this by skipping satellites entirely and connecting the plane directly to special antennas on the ground, basically turning the plane into a flying cell tower.
And the latest upgrade? Airlines are starting to use low-Earth orbit satellites, like Starlink, which orbit much closer. That cuts latency from hundreds of milliseconds down to just a few dozen, making in-flight internet almost as fast as on the ground.
So next time you’re online mid-flight, you’re not just connected, you’re linked to a network that literally spans Earth and space. Pretty wild, right?

![We’re starting (adding) a new chapter! stanford here we come…. 💻
For me, the year has always felt like it runs September to September. Something about the seasons changing into fall makes it feel like a natural reset….
Looking back, this last year has been a big one. It started with me flying to SF to interview Mark Zuckerberg. From there, focusing on expanding and growing my Talk Tech with Tiff podcast (on quality interview trying to release max one a month…) sitting down with thought leaders like Jensen Huang, Satya Nadella, Eliot Horowitz, and many others.
Outside of the podcast, life also changed in a big way: end of May we welcomed our baby boy, who by the way is coming with me on his first trip to San Francisco today (wish me luck travelling haha). Starting him early in tech, I guess.
I also focused more on public speaking, expanded our YouTube deep dives, and took on consulting with some of the biggest tech companies in the world.
And before I found out I was pregnant, I had actually started graduate studies that I ended up putting on hold. That time away made me realize how much I wanted to keep pushing myself, so I applied to Stanford and I’ll now be starting my graduate studies in AI & ML next week! I will be studying remotely of course but can’t wait for this next chapter and to share my learnings with you alll. I deciddd to do this because I talk a lot about these topics and consult on them… why not continue to gain as much education on them as I can?
I don’t know exactly how we’ll balance it all, but that’s kind of how things have always gone: we just figure it out.
Here’s to what’s next 🥂]()

![How does Google Maps still track you underground when GPS disappears?
Here’s the thing: when GPS cuts out, your phone doesn’t quit it starts guessing. But how does it do this?
It uses a system called dead reckoning. The accelerometer measures how you’re moving, the gyroscope senses turns and rotation, and the compass gives direction.
Put together, they estimate your new position until GPS comes back.
That’s why your blue dot can keep moving through a tunnel though the longer you’re without GPS, the more error creeps in.
And here’s the crazy part: the same idea is used in airplanes when satellites aren’t available.
So when GPS vanishes, your phone is basically navigating like an airplane ✈️

![A major AI milestone just dropped…
Abu Dhabi’s MBZUAI + G42 just unveiled K2 Think, the world’s most advanced open-source reasoning model. Unlike today’s 700B+ parameter giants, K2 Think delivers frontier-level reasoning at just 32B parameters… proving that AI doesn’t need to be massive to be powerful. It’s faster, leaner, and designed to be transparent in ways we’ve never seen before.
Why it matters:
-At just 32B parameters, it rivals (and sometimes beats) models 20x bigger.
-It ranks #2 in math reasoning benchmarks like AIME and HMMT.
-It’s designed for the real world… meaning faster deployment, smaller footprints, and lower costs.
-And unlike most open AIs, this one is fully transparent from training data to test-time optimizations.
This is a big step for AI: proving that smarter, leaner, accountable models may be the future, not just endless scale.]()

![The amount of tech that goes on behind the scenes to trick our brains is wild 🤯
Here’s something wild: when you watch Netflix or YouTube with Bluetooth headphones … the video you see is actually delayed on purpose.
Why is this? Because Bluetooth audio is always late. Your phone has to compress the sound into a smaller format like SBC, AAC, or aptX.
Then your headphones have to unpack it, rebuild the audio, and run it through a converter chip before you hear it. That whole process adds around 100 to 300 milliseconds of lag.
But what would happen if apps didn’t compensate? voices would look totally out of sync.
So streaming platforms secretly hold back the video to line up with the slower audio.
Pretty interesting, right? But there’s a thing… if you’re gaming or using apps that can’t delay the visuals like listening to music, you really feel the lag.
What about newer tech to fix this? There are newer codecs like these aptX Low Latency or LC3 shrink it, but no matter what, wireless audio will always have some delay. And the only true zero-lag option? A wired connection.
Share this with someone who loves to learn about new tech!

![If no one put airplane mode on their phone during ✈️ takeoff would the flight crash?!
Here is what’s really going on…
Technically, it disables all your device’s wireless communication: cellular, Wi-Fi, Bluetooth, GPS. But here’s the thing, it’s not because your phone is going to crash the plane.
The real concern? Radio frequency interference. Cell phones emit signals in the same spectrum that airplanes use for navigation and communication, especially during takeoff and landing. It’s rare, but enough overlapping signals from hundreds of devices could potentially cause noise in the cockpit.
But that’s only part of the story.
Modern aircraft are heavily shielded, and newer phones are better at isolating signals. In fact, the FAA and airlines are starting to allow Wi-Fi and Bluetooth even during flight. So today, Airplane Mode is more about network congestion and legal compliance, not safety.
And fun fact: your phone constantly searches for towers at 30,000 feet, draining your battery fast. Airplane Mode? It saves power and stops your phone from screaming into the void.
It’s not about crashing planes… it’s about managing signals in the sky.

![Why did most major tech companies decide to make their AI assistants female? Siri, Alexa, Google assistant … they all started with women’s voices. And no, it wasn’t a coincidence.
If you’re thinking of Siri or Alexa, you’re probably hearing a female voice. But why is that? It’s not just a coincidence.
Back in the 1960s, a man named John Pierce was working at Bell Labs, trying to create the first
computer-generated voice. And he made a key observation: people were already super comfortable getting help from women’s voices. Why? Because for decades, telephone operators were exclusively female.
But here’s where it gets really interesting. Studies showed that people didn’t just accept female voices they actively preferred them in helper roles. We found them more welcoming, more
trustworthy, and yes, less threatening than male voices.
So when tech companies started creating AI assistants, they weren’t just copying what came before, they were tapping into decades of social conditioning. Pretty wild, right?

![This blew my mind… some bullet trains don’t even touch the tracks? They actually hover… no wheels, no friction. But how can something that heavy float at all?
They use something called magnetic levitation, or maglev. Powerful magnets in the track repel magnets on the train, lifting it a few centimeters off the ground. But here’s the real question: once you’re floating, how do you actually move forward?
That’s where another set of magnets comes in. Instead of just repelling, they’re arranged to pull the train forward. Imagine a magnetic wave racing down the track, the train is basically surfing that wave. Pretty wild, right?
But if there’s almost no friction slowing it down… just how fast do you think it can go?
The fastest test train in Japan hit over 600 km/h. That’s faster than a jet taking off, yet smooth enough for passengers to sip coffee without spilling. So is this the future of travel…?

![This blew my mind… your phones GPS finds you using time, not maps.
When you open Google Maps, you might think satellites are sending down your location. But they don’t send maps at all. They send time signals… precise atomic-clock timestamps. So how does your phone turn those timestamps into your exact spot on Earth?
Here is how it works.. your phone measures how long each satellite’s signal took to arrive.
Since signals travel at the speed of light, even a delay of a few billionths of a second means you’re thousands of meters closer to one satellite than another.
By turning those times into distances, your phone draws invisible spheres around each satellite.
Where those spheres overlap… That’s your location. With at least four satellites, it locks in your latitude, longitude, and altitude with meter-level accuracy.
And it only works because those satellites carry atomic clocks so precise they drift about a billionth of a second per day. Think about it: if the timing was off by just one microsecond, your GPS would be hundreds of meters wrong.

![Can someone unlock your iPhone with Face ID… while you’re not looking? The tech behind this is really cool! But don’t worry for most people this setting is set to ON for default.
Here’s what’s going on: Face ID uses an infrared camera, flood illuminator, and over 30,000 invisible dot projections to map the exact geometry of your face in 3D. It matches that map to the one stored securely in your iPhone’s Secure Enclave.
So if your face matches, even with your eyes closed, it unlocks. Which means if you’re asleep, distracted, or even unconscious, someone could access your phone.
The fix is simple: in Settings → Face ID & Passcode, turn on Require Attention for Face ID. That forces the system to use infrared sensors to confirm your eyes are open and focused before unlocking.

![What if I told you... the thumbnail you see on Netflix isn’t just a guess it’s calculated, personalized, and optimized by a machine learning system built to predict exactly what you’ll
click?
Here’s what’s happening behind the scenes:
For every show or movie, Netflix doesn’t make one thumbnail... they create dozens. Different characters, colors, even different emotional tones.
And to figure out which one to show you, they use a contextual multi-armed bandit algorithm.
It’s a type of machine learning that makes decisions by balancing two goals:
Exploration: testing new thumbnails you might like
Exploitation: using thumbnails it already knows you engage with.
Each time you open Netflix, the algorithm pulls in your context your viewing history, browsing behavior, even subtle signals like which thumbnails you hovered over but didn’t click.
Based on that context, it chooses the thumbnail with the highest predicted probability of getting you to engage. And it keeps learning in real time, a technique called online learning.
It’s not just trial and error. Every interaction you have becomes feedback.
In fact, Netflix even tracks how artwork affects completion rates not just clicks tying thumbnail selection to actual watching behavior.
So the next time you scroll through Netflix thinking you’re choosing what to watch...
Remember: their machine learning system chose the thumbnail specifically for you before you even made your choice.

![This blew my mind when I first learned about it! However there are some big limitations to when it’ll work… the tech is there but since 2018 restrictions have been put on use cases because of things like Face ID for extra verification.
This feature relies on a special chip inside your phone called the secure element. It can store just enough power from NFC terminals to let you use stored passes but with some big limitations:
iPhones: Since the iPhone XS (2018), Apple allows only your default transit card (like in Apple Wallet for subways/buses) to work when the phone is dead. You can’t buy coffee or pay at a store this way it’s strictly for transportation.
Android phones: Some models support a similar feature, but it depends on the manufacturer and whether they’ve enabled it. Like iPhones, it’s mostly limited to transit cards, not general payments.
Why? Authentication. Normally, Face ID, Touch ID, or your passcode verifies you. With the phone off, that’s not possible so Apple and Google restrict it to low-risk, high-convenience cases like public transport.

![You probably don’t realize this… but whether you’re on iOS or Android, your phone is actually running two computers at the same time and one of them you’ve never seen.
It’s called a Trusted Execution Environment, or TEE and it’s built right into your phone’s
processor.
Think of it as a tiny, locked-off computer inside your main one. It’s there to handle your most sensitive information things like your fingerprints, payment details, and encryption keys in a space the rest of your phone can’t even look into.
When you do something secure like scan your face, unlock a file, or approve a payment your request skips Android or iOS completely and runs inside the TEE.
But what if a hacker took full control of your main operating system? It has its own stripped-down operating system, its own memory, and everything in there is encrypted.
So they still couldn’t get inside.
And it’s not just in phones you’ll find TEEs in laptops, game consoles, even cloud servers. It’s basically a vault, welded right into the hardware.

![Delete an app, and your personal data is deleted too… right? Not exactly. A lot of apps can keep tracking you long after they’re off your phone.
When you install an app, it often creates an account or a unique ID for you on its servers, that’s where the real tracking happens. Deleting the app just removes the interface from your phone. The account, and all the data it’s collected, still exist.
Some companies go further, using device fingerprinting which is details like your phone model, IP address, and system settings to recognize you even if you reinstall later. And if you signed in with Google, for example, your activity can still be linked across other apps and websites.
The only way to really stop tracking is to delete your account directly with the company.
So… have you actually stopped that app from tracking you or just made it invisible on your home screen?

![How does Netflix block you from password sharing?
When Netflix announced a password-sharing crackdown, most people thought they’d require logins or two-factor codes.
But the tech is way more subtle and smarter.
Netflix uses a combination of device fingerprinting and home network analysis.
That means they track:
-What device you’re using
-Your IP address
-Your connection type
-Even the way your device behaves when streaming
They create a digital fingerprint so if you’re suddenly watching from a new Smart TV 800 miles away on a different Wi-Fi?
That raises a flag.
They also use heuristics pattern detection.
Maybe you log in from one place 90% of the time… but your roommate logs in from 5 cities in 3 months? That’s suspicious.
But here’s the interesting part:
Instead of locking you out, they “nudge” you.
Netflix lets you add “extra members” or verify new devices because they know too much friction means canceled subscriptions.

![How did someone think to invent this?!? It’s wild to me. In this video we’re breaking down how do noise cancelling headphones actually cancel sound?
Here’s what’s happening: Most ambient noise like the hum of an airplane engine or a train… is low-frequency, predictable sound, usually under 1000 Hz.
Noise-canceling headphones have outward-facing microphones that constantly sample these incoming pressure waves. Then, a digital signal processor (or DSP) analyzes that waveform and calculates its inverse… a sound wave that’s equal in amplitude but 180 degrees out of phase.
This inverse signal is played through the speakers inside your earcups at the exact same time the original noise hits your ears. The two waves interfere destructively, meaning they cancel each other out at every point. That’s destructive interference.
All of this happens in under a millisecond. The DSP needs to process, invert, and play back the signal before your brain can even register the noise.

![Apple Pay is one of the only payment systems built not to track you.
They literally designed it so they can’t see what you buy.
When you use Apple Pay, your real credit card number is never sent to the store.
Instead, Apple creates a Device Account Number a unique token stored securely in your phone’s Secure Enclave.
That token stands in for your real card.
And every time you tap to pay, your iPhone generates a one-time dynamic security code, like a temporary CVV.
So what does the store get?
Just a random-looking number, tied to a single transaction.
They process the payment like usual but they never see your actual card.
And Apple? They don’t store your transaction history.
In fact, they don’t even know what you bought, how much it cost, or from which aisle.
That’s all handled between the merchant and your bank.
