  • Phones encrypt the data by default, your password or pin is also needed to authorise the connection with a computer.

    However, many people do insecure things like storing passwords etc in Notes applications, or having simple PINs that are easy to guess, don’t update their devices, or even turning off security features (if they can) because they won’t take a small amount of time to understand them.








  • I’d say companies THINK they will make more money. That might be true with big, complex software that can be sold as a service that people will use (Photoshop, Windows, Office etc) or services that offer a lot (like the original version of Netflix or Amazon Prime)

    But it’s not true for things you can take or leave. (Such as most mobile apps which now have to really on sales to boost conversion rates from Free tier to subscription).

    Then you also have the issue of a fragmented market so even previously successful services like Prime are looking to get more money by adding extra costs (eg Prime Video will have adverts from the summer unless you pay $40 extra per year as a new top up subscription)

    So it’s more of a theoretical reliable income.






  • Photons are massless and along with other massless particles are known as Luxons because they always travel at the speed of light. But notice that the speed of light varies depending on the medium that light is crossing. (Eg 300,000 m/s in a vacuum . 200,000 m/s in glass)

    So you could certainly transmit data faster than light through glass by simply transmitting it in a vacuum. But there’s little practical use except perhaps gravity wave detectors.

    There are a class of particles that always travel slower than light (unless you accelerate them with infinite energy) and also a theoretical and controversial class of particles that travel at infinite speed and would require infinite energy to slow them to light speed. (If they did exist no means has ever been postulated to detect them)






  • As well as the charges issue there are three other points.

    They are delivery reports not read reports.

    Because of the way they are implemented they are low priority on the network and will be dropped at busy times. (This means the lack of a delivery report doesn’t necessarily mean it wasn’t delivered)

    They don’t work reliably across different message centres. If you and the recipient are on different message centres, You’ll get a delivery report when it reaches the next message centre. (This means that a delivery report doesn’t necessarily mean the message was delivered)
