When you type an email address in Gmail... It tells you instantly if it exists. No loading. No searching billions of accounts. INSTANT. How? Google doesn't search anything. It already knows. This is called a Bloom Filter. And it's one of the most beautiful hacks in computer science. @vijaydecodes

@katyXBT Step 1: don't trade 😅 but seriously — only put in what you'd be fine losing, never buy what you can't explain to a 10yr old

Any advice on how to avoid losses in crypto?

@asaio87 Tell that to the 50k devs laid off since Copilot and Codex shipped 😅 decades is doing a lot of heavy lifting in that sentence

"All dev jobs will be replaced by AI" is at least decades away

@WeekendInvestng RBI capped foreign MF investments at $7B back in 2008 and never raised it. Meanwhile rupee hit ATH lows and Nasdaq did 800% since then. We were protected from currency risk and also from the biggest wealth creation in history 😬

We are near ATH again on USDINR Keep dreaming of 50s and 60s!

@sumitkbehal BSE didn't bet on markets. It bet on Indians' addiction to options trading. Genius until SEBI ruins the party 👀

BSE is up 5400% in 5 years The company transformed a ₹10 lakh investment made in 2021 into ₹5.4 Crores by 2026 by serving as a virtual casino for option traders BSE is a bet on growth of gambling in India

@ArthurMacwaters $7.5T valuation on a mission where one bad reentry ends the whole thesis. Biggest ambition in human history but the margin for error is literally zero. Respect the vision tho 🚀

There is a good chance SpaceX is the first $10T company The scale of the mission is just simply larger than any other company in existence

@zuess05 Traded 1 boss for 50 customers who all think they're your boss 😭

Quitting your 150k tech job to "vibe-code" AI apps is the biggest trap of 2026. You think you are escaping the matrix. But you just go from answering to one annoying PM... To answering to 50 angry customers who pay you $9/month and threaten to ruin your life if you don't fix a bug at 3 AM. We really romanticized unemployment. 🫠

@Barchart Every bubble said "this time is different" right before it popped. But dot com gave us websites. AI is eating the cost structure of every industry simultaneously. The chart looks the same. The story really isn't 👀

AI Bubble hits same concentration level that resulted in the bursting of previous bubbles, including the Dot Com 🚨🚨🚨

@InvestorOfJAMMU The foreign reserves angle is genuinely underrated — India spends $100B+ importing crude every year and we're literally sitting on sugarcane. E100 can't come fast enuf tbh 🇮🇳

Waiting for Indian Auto companies to launch E100 compliant Bikes and cars. Why we need to import Crude oil when we have Made in India Ethanol🩵 We can export it too and earn foreign reserves.

@XFreeze Raptor 1 to Raptor 3 is 185tf to 280tf in just a few years and they're still not done. The Soviets spent a decade on RD-270 and never even flew it. SpaceX just casually lapped 60 years of rocket engineering 🤯

Raptor 3 is engineering black magic SpaceX’s Raptor is the FIRST full-flow staged combustion engine to ever fly - only the 3rd ever built (after the Soviet RD-270 and the 2000s US demo that never flew) → Both fuel-rich + oxidizer-rich preburners → 100% of propellant through the turbines before the main chamber → Auto-ignites from hot preburner gases (no Merlin igniter fluid) → Record 350 bar chamber pressure Raptor 3 goes even crazier: Everything internalized with regenerative cooling. No heat shields. No fire suppression system. Saves 10+ tons This is how Starship becomes rapidly reusable

@Atulsingh_asan The real winners here aren't oil companies. It's the ethanol producers, sugar mills and flex-fuel engine manufacturers quietly sitting in the background. The infra play is always more interesting than the headline. 👀

85% ethanol with petrol Will petrol prices come down after blending?

@his_eminence_j Just like "organic" food. Nobody asked if pesticides were harmful until they were everywhere. Then "no pesticides" became the premium option. "No AI used" is going to hit the same way. 👀

Very soon, “no AI was used” will be a premium service category in nearly every industry. Mark this.

@yashhq_22 Same thing people said about spreadsheets in 1980. "Why do I need Excel when I have an accountant?" The accountant didn't disappear. But the one who learned Excel ran circles around the one who didn't. 📊

Right now AI agents feel like a leverage. In a year, they’ll feel like running a business without them was insane.

@DimaZeniuk Three years ago it exploded on the pad. Now we're casually scheduling launches like flight bookings. SpaceX broke the word "impossible." 🤯

SpaceX could launch Starship in a few weeks

CZ has been saying this since 2018. To be fair, he's also been saying it from prison. 😅

@TheCaptain1386 @NASAhistory Yeah great achievement !!

@vijaydecodes @NASAhistory It's still the closest man-made object to ever approach the Sun.

Today marks five years since a human-made object first touched the Sun. On Apr 28, 2021, during its 8th flyby, NASA's Parker Solar Probe entered the Sun's superheated atmosphere—the corona—for the first time, flying 8.1 million miles above the solar surface. To date, Parker has made 27 close approaches to the Sun, each time helping us understand more about our host star and the space weather events it creates.

Copilot pricing just went wild… Opus 4.5: 3 → 15 (5x) Opus 4.6: 3 → 27 (9x) Opus 4.7: 7.5 → 27 (~3.6x) AI was “for everyone”… till the bill showed up 😂 Accessibility down, costs up. OG vibe coders had a good run… real coders back now? 👀 #GitHubCopilot #Copilot #Claude #AI #TechTwitter

@JT2142_ @shiverr12_ @NASAhistory Why people feel anybody doing research and writing something to help add value just to increase his value as a small account is AI is out of my bounds Let me know if I can help you out

@shiverr12_ @vijaydecodes @NASAhistory He definitely did. Even the subsequent responses. You can also take a look and notice he's Indian, so no surprise here at all.

India vs US in AI: The Real Gap (No Copium) Right Now (2026): • US → 500k–1M+ frontier GPUs | ~$450B in AI • India → ~38k (public + private) GPUs | ~$7.5B in AI → 10–20x gap By 2030 (if we execute hard): • US: 2–4M+ • India: 500k–2M (aggressive) This is not a talent issue. India has the best engineers. It’s power + data centers + capital — the real moat. GPUs grab headlines. Infrastructure wins wars. If India nails cheap reliable power + gigawatt-scale DCs, this gap shrinks FAST. The real question: Will India build a sovereign AI stack (own models + infra) — or keep renting from foreign clouds forever? Time to move from “AI talent nation” to “AI power nation.” #IndiaAI #AI #TechTwitter #AIInfrastructure

@NASAKennedy 14 years and still cooking… Curiosity is unreal From proving ancient water to finding complex carbon molecules — this mission basically rewrote what we thought about Marsone rover, massive impact 🚀

🚀Launched from Cape Canaveral Space Launch Complex 41 in 2011, 14 years on the job (on Mars no less), and Curiosity is still finding new discoveries!

@NASAhistory If you’re wondering what 3–7G feels like & how to experience it 3G = roller coasters 5G = aerobatic flights 7G = centrifuge / fighter jet your body at 7G: “we should not be here” 😵‍💫

After briefly experiencing forces up to 7 g during reentry, Apollo 16 astronauts John Young, Charlie Duke, and Ken Mattingly splashed down OTD in 1972, completing NASA's fifth lunar landing mission. With them were 211 pounds (95 kg) of lunar samples and 22 magazines of film with more than 2000 images from their mission.
