🔍 Reproducibility Verified: @SeedSigner v0.8.6 ✅
We independently rebuilt the image for Raspberry Pi Zero 1.3 and confirmed a bit-for-bit match with the official release.
This strengthens trust in SeedSigner’s transparency and security.

This is actually a job in the Philippines. They pay "coconut climbers" about 2 PHP per coconut they bring down.

It would actually benefit Mixin Messenger's Users, if their communications were not misleading.
Image 1 appears to show that the desktop app has a "crypto wallet"
Image 2 is the documentation - which you'll only read if you're a guy like me. Otherwise, you would be given the run around to install the desktop app, then the mobile app - which is needed to run the desktop app - before realizing that the desktop app does not have a wallet!

🚿⚡ Can you generate electricity from municipal water pressure?
Yes — it’s called in-pipe hydropower. I did the math:
💧 A typical household tap at 60 psi and 10 liters/min can theoretically generate:
🔋 ~67 watts of power
🛠️ Realistically: ~30 watts usable (50% efficiency)
Sounds cool, right? But there’s a catch:
❗ It only works while water is flowing (shower, faucet, etc.)
❗ You could restrict your water pressure
✅ But yes — it can power a light or sensor in the right setup
🌍 Cities like Portland, Oregon use this to generate electricity from water mains!
Ha!
If you have 5,000 liters of water stored 30 feet high, you can get:
➡️ ~124 watt-hours of potential energy
➡️ But with 50% efficiency (real-world losses), you only get ~62 watt-hours
That’s enough to:
🔋 Fully charge a laptop once
💡 Power a 10W light for ~6 hours
📶 Run a Wi-Fi router for 3–4 hours
To power a 50W laptop for 8 hours (400Wh), you’d need:
💦 ~32,000 liters of water falling from 30 feet every day
🎯 Assumptions:
Laptop power usage: ~50 watts (moderate usage)
Time: 8 hours
Required energy:
50 W×8 hrs=400 Wh/day50 \text{ W} \times 8 \text{ hrs} = \boxed{400 \text{ Wh/day}}50 W×8 hrs=400 Wh/day
💧 Let’s reverse-engineer how much water is needed from a 30 ft (~9.14 m) drop:
We’ll use:
E=m⋅g⋅h⇒m=Eg⋅hE = m \cdot g \cdot h \Rightarrow m = \frac{E}{g \cdot h}E=m⋅g⋅h⇒m=g⋅hE
Where:
EEE = 400 Wh × 3600 = 1,440,000 joules
g=9.81g = 9.81g=9.81, h=9.14h = 9.14h=9.14
m=1,440,0009.81⋅9.14≈16,113 kg (liters)m = \frac{1,440,000}{9.81 \cdot 9.14} ≈ \boxed{16,113 \text{ kg (liters)}}m=9.81⋅9.141,440,000≈16,113 kg (liters)
⚠️ Adjust for 50% Efficiency:
16,113×2= 32,226 liters/day16,113 \times 2 = \boxed{~32,226 \text{ liters/day}}16,113×2= 32,226 liters/day
✅ Final Answer:
To power a 50W laptop for 8 hours/day using only water falling from 30 ft, you’d need:
~32,000 liters per day
That’s about 32 large water drums (200L) falling from that height daily
The Return of the King
Now is the time for the king to unite his people, marshal his forces, eliminate the holdouts - and bring freedom and democracy back to Iran. #FreeIran

I just love this.
Would want to travel to Japan someday. Maybe even live there
The Return of the King
ایرانیان، شاهزاده تبعیدی شما، اکنون بازگشت پادشاه خواهد بود.
اکنون لحظه شماست.
سپس از آنجا می توانید به یک کشور دموکراتیک-سکولار بروید. از این فرصت استفاده کن شما هرگز با آیت الله چنین نخواهید داشت.
This kid has been branded as "right wing", but i find no evidence of that. His approach is Socratic and very respectful to people who don't have the same views as him.
