Visa is valued at $585B and Mastercard is valued at $444B. Is Stripe making more revenue per transaction than Visa and Mastercard?

Lithium NMC, which I think is the most common, is 3.7V. Lithium iron phosphate, which some power packs do use, has a nominal voltage of 3.2V.

Why is this an app and not a website?

Yes, they are on the BIS Commerce Control List. It doesn't need to be particularly advanced to be export controlled.

5A001.g Passive Coherent Location (PCL) systems or equipment, “specially designed” for detecting and tracking moving objects by measuring reflections of ambient radio frequency emissions, supplied by non-radar transmitters. Technical Note: For the purposes of 5A001.g, non-radar transmitters may include commercial radio, television or cellular telecommunications base stations.

Ask HN: How do middle schoolers talk to each other if they don't have phones?

syedkarim — Mon, 02 Jun 2025 15:35:31 +0000

I have a kid starting middle school in the fall. She does not have her own phone and neither do any of her friends. None of her friends have home phones, either. So how do middle schoolers talk to each other over summer break? I'm assuming her situation is not unique, so this is a general question.

SpaceX isn’t providing a discount to student groups. The program, Cubesat Launch Initiative, is funded by NASA and covers the cost of launch and integration into the deployer.

Thanks for the reply. Are you able to comment a bit more on the costs. I’m particularly curious about your statement about balloons being orders of magnitude less expensive than satellites. Does that mean 1/1000 the cost or 1/100 the cost? I ask because LEO satellites with usable power (50W) no longer cost millions, or even a single million to put on orbit. And they have operational lifespans of 5 years.

Are you staying under the 12-pound ICAO-limit for a payload (which must be split into two packages)? If so, how much power is continuously available to the payload and how long can each balloon stay aloft?

Why do unsubscribe-regulations work so well? What is the punishment for not complying and is enforcement particularly swift?

Which part of it do you think is not true? The written application is not extensive at all. It takes maybe 1-hour of focused time. That’s all I had ever spent on the written part of the application and I’ve been interviewed three times as a solo founder. And the interview really is just ten minutes long, though sometimes they go a little over the limit.

Alternatively, the aperture of the antenna on the satellite can be increased. So high-gain from space, but low gain on Earth, which is the approach of AST SpaceMobile.

Ask HN: What do you use as a home phone, if you have kids without phones?

syedkarim — Thu, 19 Sep 2024 13:59:47 +0000

As an adult, I have never had a landline in my home. I now have several pre-teen kids and none have their own cellphone. When the older ones are home alone, I leave out an old iPhone that is connected to the home wifi network; that's enough for them to call family (through Facetime) or 911. But this isn't ideal because the phone is not always charged or the younger kids hide it. Is a landline the only real solution?

$5 is not even the price of the tuner (R860) at the MOQ of 4900 pieces. Where are you finding new RTL-SDR dongles for $5?

What’s strange is that it’s just a PCB. It should not be an issue for them to stock or quick-build a circuit board. They can’t possibly still blame the chip-shortage bogeyman.
