More like WhatsApp is a Signal clone. Whatsapp uses the signal protocol for its encryption. Or at least it did until the Zuck took it closed source. It's still at least, in part, signal though.
Course Signal is still very barebones. Great for a secure messenger, but not as super featured like telegram. Would've been nice if they kept SMS compatibility though.
At 85 dB you'll have hearing damage from long term exposure without hearing protection. Normally considered 8 hours a day 5 days a week. So 2000 hours in a year. Higher sound levels have a lower threshold so shorter times. 120 dB is the threshold of pain, so immediate hearing damage. Also, dB are a 10x log scale. So every 10 dB is an order of magnitude increase. So the siren is actually about 3000x louder than when you should start wearing earpro.
Nah, FL5 Type 5 has hill assist, rev match, anti stall, and brake lock. With really comfy bucket seats. At speed you got Honda's bitchin adaptive cruise control and lane keeping assist. It's as comfortable as a manual car can be for commuting and traffic. 10/10 would recommend as daily driver.
Signal protocol is what you're looking for. Started as text secure then changed name eventually. Whatsapp was never opensourced they just used the Text secure (now signal) protocol for their encrypted messages. They still allegedly use the signal protocol, I think, but with it being fully closed source and not implementing current signal feature for years afterwards.
In other words I have a high degree of faith our nuclear secrets will only be leaked to me when our DUI hires add me to the group, again using signal. But guarantee they're also leaked to the Zuck using whatsapp.
