Welcome to my weekly letter, where I share a few noteworthy articles and my own commentary. Without further ado…
Weekly Read
- The world’s first integrated quantum communication network (phys.org) – TL;DR: the world’s 1st quantum communication network for ‘Quantum Key Distribution’ (QKD) for cipher key exchange in a secure communication… e.g. it also happens at the beginning of a TLS/SSL/HTTPs secure connection, where both ends agree on a cipher suite to encrypt the connection. I do not see a benchmark comparison between QKD and TLS though, so I am not 100% clear what’s the value of this work…
- The Arctic Ocean Is Teeming With Microfibers From Clothes (Wired) – if you haven’t read my earlier issue on sustainability, it’s not too late yet. There are really many many things we can do to help with sustaining our Earth. This article talks about plastics in our clothing.
- FAA Files Reveal a Surprising Threat to Airline Safety: the U.S. Military’s GPS Tests (IEEE Spectrum) – an interesting piece on aviation safety, and it notes that the problem is worsen with autonomous planes and drones tech. Time to use tech to solve issues than to create them?
- How Steel Might Finally Kick Its Coal Habit (Wired) – another venue to achieve overall sustainability goal, reduce/eliminate coal use for steel making. This is specially interesting now that President Biden is pushing forward with a $2 trillion infrastructure and climate plan.
- Microsoft’s Dream of Decentralized IDs Enters the Real World (Wired) – other than cryptocurrency and NFT, blockchain technology shows another potential application here – identification. It’s noteworthy to compare this approach with the common model, being ‘federated identity’, as noted in the article and other sites (1, 2) the problem this can help solve is user data privacy.
Have a nice weekend!
