Just created a complete analysis of AI infrastructure opportunities covering chip manufacturers, power companies and system integrators. I shared this analysis with my 20,000+ students. For 24 hours, it's yours for FREE. Like, RT & Comment "AI" and I'll DM it to you.

@anggadmnk "uang ketabung ga kepakai" do some investment on assets maybe..

Craziest DM I ever received, from a VP at a global retailer: "Our app is shit and we know it's shit". I met her for coffee and she asked me if I could solve the biggest unsolved problem in retail. This is a deep dive into why and how Hyper built a 1m-accurate indoor GPS. This DM arrived in 2017. My outdoor AR navigation demos had just gone viral, and my new open-source project for Apple had elevated me to be the top trending iOS developer on GitHub. The retail exec told me they wanted to bring indoor maps and navigation to their retail stores, so customers could find what they’re looking for, and they could pop up relevant promotions along the way. It turns out that every office, university, events venue, hotel, airport, warehouse, factory — basically everywhere indoors have some need to navigate people around, provide relevant information, and improve efficiency. I assumed this was a solved problem. No. They do have maps on their app, but they aren’t able to navigate people because GPS doesn’t work indoors. They tried every solution out there to provide the blue dot, but nothing worked. I did know something about maps and location already — the first startup I worked at built an early version of Pokemon Go. I’d been tasked with generating the gamified maps, and populating the monsters and rewards. So I knew a bit about maps, coordinates and GPS — and monster training. But indoor navigation was new to me. Over the years, I’ve slowly become an expert in this, so let me explain. For indoor navigation to work well, the blue dot location needs to be 2x as accurate as a strong GPS signal. An aisle in a store is usually about 2 meters wide, so an accuracy wider than 2 meters would be fixing you in the wrong aisle. There are many research studies aimed at solving this, and Apple and Google have made acquisitions to help them in this area over the years. There were also many startups who claimed to have solutions, but when I spoke to their customers, I discovered that they weren’t happy with anything they’d tried: - Bluetooth beacons. Install thousands of these small sensors, which are a bit like AirTags, and use them for triangulation. But the bluetooth signals are noisy, making the location about 5 meters accurate, so it would jump you between multiple aisles in a store. Plus, lots of infrastructure to maintain. - WiFi. More promising than beacons, because every business has WiFi installed already. But the same radio signals problem means the location isn’t accurate enough. - Magnetomers, which use the earth’s magnetic field. This one sounded more promising. But it takes several minutes of walking around until it will give you a “blue dot”. So this was a bad user experience. - Computer Vision, which works like Google Street View. The user holds up their phone to scan the environment, it recognises their surroundings and locks them in. But this is clunky for the user, and they need to do this repeatedly every time they want a location update. Once again, bad user experience. Here’s an example of Apple’s own accuracy using WiFi. (I’ll show our own performance on these same sessions further down).

Have you guys heard of ✨relational algebra✨?

Hi, aku mau share loker dari side job company aku, senior frontend engineer, highly skill on react + react native. ON SITE di bali, Salary start at 25jt++ vacancies: 2 org. boleh kirim cv nya di dm yah.

if Cursor writes this React code, DON'T ACCEPT IT! i spent the last 2 weeks fixing unnecessary useState + useEffect sync. this is unmaintainable and adds tech debt unless you have a good reason, don't do this!

saya suka perdebatan di pagi hari xixi..

njirrr mau di tembak sama arsenal ... meriam mau meruntuhkan kerajaan 🔥

"You never walk Alone" respect banget sama liverpool, mereka deserve menurut gue Thropy UCL musim ini,sebagai madridista, sangat ikhlas ga dapet UCL musim ini, trust me gess, tidak satupun dari london akan ke final klo itu bukan liverpool! you guys deserve it more better!

damn... why not rust? because...

bntar, ini emng semudah itukah pinjol? berarti klo data ktp kita bocor, enak banget dong di buat pinjol? atau harus foto selfie pake ktp? serem njirr baru tau.. fak, malah data ktp di indo dah bnyk yg bocor lagi

@sarbeh_ alhamdulillahh, sukses selalu mas, semoga nular 🔥

damn.... finally ada yg bring this problem within the solution 😭

I'm happy to announce that I can't take it anymore

@ZikriIsmal gapernah wkwkwk

it is surprisingly catchy and energetic
