The era of AI is booming, and recently the US stock market's storage sector has been talked about every day, with NAND, DRAM, and HBM flying everywhere. Do you all know what they are? 😂 Here's a popular science post to boost your knowledge 1. NAND Pronounced /nænd/, roughly like "Nan-de" in Chinese. Full name NAND Flash, which is flash memory. Its main feature is that data is not lost when power is off, providing persistent storage. It's everywhere around us: SSD solid-state drives, USB drives, memory cards, the 256G or 1TB internal storage in phones—all of these use it. Large SSDs in enterprise servers also use NAND. SanDisk's core asset is NAND; AI datasets and vector databases ultimately rely on it. In short, it's used for storing data. 2. DRAM Pronounced /ˈdræm/, roughly like "Dram." Full name Dynamic Random Access Memory, which is the running memory. All data is cleared when power is off, but it's much faster than NAND. Corresponding products include computer RAM sticks, 12G/16G phone RAM, and server memory. Temporary data during GPU computations is stored in DRAM. In short, it's used for running processes; it doesn't store data long but runs fast. 3. HBM No need to memorize the pronunciation; just say the letters one by one. Full name High Bandwidth Memory, a high-end upgrade of DRAM. While regular DRAM chips are laid flat on the motherboard, HBM stacks multiple layers of chips vertically, maximizing bandwidth. High-end AI GPUs like Nvidia H100/H200 and AMD MI series come standard with HBM. Note that HBM is not a separate category; it is still part of the DRAM family, just a high-end form. Production mainly relies on three companies: Micron MU, Samsung, and SK Hynix. Finally, just remember roughly: NAND is for storage, DRAM is for running processes, and HBM is a special fast-running memory for AI. Is everything clear now? #AI 🦧 #USStockMarketKnowledge

I'm planning to start trying out some new creator earnings from Kaito Studio, but I'm not sure if it's worth it? Since Kaito reconciled with X, it seems like fewer people are participating in the new mouth-rolling gameplay. I haven't really seen much of it on my timeline, maybe because I haven't been playing or paying much attention. Kaito needs a breakout moment, a big result from a mouth-rolling project; then probably many people will pick it up again. The first new mouth-rolling project is @axisrobotics, which just finished its initial offering. Whether it can rise and lead a new wave of Kaito mouth-rolling depends on Axis's scale~ Also, I recently discovered @0xhazels, a new super powerful NFT project. The equity-type genesis NFT is about to launch, and on October 1st, a two-week $15,000 creator event will start simultaneously. I suddenly have a feeling that this time Hazels might just take down Kaito~🫣

Starship really entered Earth's orbit this time, launching 26 satellites in one go, sending the new generation Starlink V3 satellites into space. The process was even more eventful than the result: one Raptor engine on the ascent stage shut down prematurely, and a SpaceX spokesperson said on the spot that it wouldn't reach orbit, but the orbital ignition still succeeded. However, the mission didn't complete the full duration; originally planned for ten hours, it ended early with a splashdown in the Pacific. SpaceX's stock price fell 2% that day, with volume higher than the previous days, and the price steadily declined. At first glance, I really didn't understand the market reaction to what seemed like a successful flight. Looking back, I guess the market was focused on the engine issue and whether the subsequent launch schedule could be maintained. On the A-share side, the sentiment was exactly the opposite; the commercial aerospace concept stocks have been actively accumulated by margin traders in advance these days. The same news caused a sell-off in US stocks but buying in A-shares, which is quite interesting. We'll see at today's opening whether this sector can hold on.

Can't projects in the crypto space just do direct airdrops? So much simpler. They have to do new token launches one by one to sell chips. Sell, sell, sell, but can't go to the big A to ring the bell. 🌝 Recent new launches: $AXIS $JUMP $ETHOS

RT @oceansbaby_: In various investment circles, the principle basically never changes~ If you look at this issue from a game theory perspective, you will find that, it is necessary to trap retail investors at the high point, which is beneficial to society as a whole. Only by trapping a large number of retail investors at the high point can they give up the illusion of financial freedom and be motivated to create diligently. 😂 https:/…

Everyone have a happy workday, Work 3 days and rest 7 days. After hardship comes sweetness, hehe✌️

Fortunately, I was busy these past two days and didn't have time to be on the chain, otherwise I definitely would have been involved in the giwa fake chain incident. It's fate; besides my own mistakes, I haven't suffered any major losses.

The moon on the 15th is rounder than on the 16th. Yesterday morning, I received Mid-Autumn mooncakes from @GMWalletHK and @KittanSex, super happy, and started eating them right away last night. The kids at home said the taste was delicious and especially liked the exquisite box for the mooncakes, haha, very thoughtful 🫡 Thanks to the bosses for their kindness, wishing GM all the best!

Have you seen people walking cats and dogs? Have you seen people walking ducks? 😂 Haha, so funny #LifeSnapshot

Riding on the recent low traffic, I'll first boost my followers a bit. Theoretically, everyone who comes to X has their own ideas: Some purely want to share, those who are good at sharing Some just ramble, people who like to vent and relax Of course, more are there to gain Elon’s appreciation and, along the way, earn some hard-earned money. Right? So which type are you? You need to figure this out to better find like-minded people.
