Glass vs plastic when it comes to bottled water

When glass is recycled it gets turned in to more glass. It can be recycled over and over and never lose its integrity.
Plastic bottles, however, are not recycled into plastic bottles. The plastic loses its integrity and needs to be turned into something different such as plastic lumber or carpet padding. Because of this, some people say that plastic isn’t truly recycled; it’s downcycled.
Every time a product is packaged in a plastic bottle, jar, or other container, it’s new plastic. All new resources went into making it. Glass jars, on the other hand, can be made from recycled glass.

Protanomaly: a type of red-green color blindness in which the red cones do not detect enough red and are too sensitive to greens, yellows, and oranges.
As a result, greens, yellows, oranges, reds, and browns may appear similar, especially in low light. It can also be difficult to tell the difference between blues and purples, or pinks and grays. Red and black might be hard to tell apart, especially when red text is against a black background. Read more

How to Build a Successful Career in Information Security / Cybersecurity
Some great advice from Daniel Miessler:

  • learn to code
  • build your lab
  • build your portfolio of projects (make sure you own your data)
  • practice with bounties
  • get involved – contribute to open source projects
  • be active, engage in conversations
  • network with others
  • participate to conferences
  • find a mentor
  • get certified:
    CISSP is the closest thing to a standard baseline that our industry has. It’s actually better than a computer science degree in a lot of organizations
  • most importantly: have passion!

I am currently reading Solenoid, by Mircea Cartarescu, a surrealist novel that shows, among others, the challenges of growing up in Bucharest during the communist era.

In a nutshell, the novel is presented as a manuscript of a failed writer who teaches Romanian at an elementary school in Bucharest, hates his job and wishes to find an escape route from the confinement of his body and the three-dimensional world around it.

MCAS (Maneuvering Characteristics Augmentation System) seem to be the faulty mechanism behind the Boeing 737 Max recent failure.
If an outside sensor measuring the angle-of-attack reports that its nose is aimed too high, the MCAS is programmed to automatically lower it, allowing the plane to regain speed and lift. But if this sensor is broken (and it looks like there was no redundancy), then the MCAS will be incorrectly trigerred, causing the aircraft to dive.
A longer explanation here.

Collect less data and get rid of it faster.

I believe that the Airpods success can be explained by the bandwagon effect: “the rate of uptake of […] trends increases the more that they have already been adopted by others“. They slowly made their way from mockery to status symbol.

At first sight, a bank card with a built-in fingerprint reader seems to be an excellent idea, right? You trade the PIN code (something that you know) for your fingerprint (something that you are). From an usability point of view, it’s a major step forward (PIN codes can be forgotten, misplaced, shoulder-surfed, reused, social engineered, etc). But from a privacy point of view things don’t look so good anymore. The initial plans indicate that the users still have to walk in a branch to enroll their fingerprints – which
(probably) means that the bank will get to know your biometric data. Which cannot be reset, as we all know.
A possible alternative is to ditch the bank card altogether and use something that you have with you all the time: your smartphone (see Apple Pay, Google Pay) – in addition to your biometric data which never leaves your device. But this solution is not inclusive: not everybody owns a smartphone.

The results of this study are really sad and shows that in reality, we are far, far away from secure-by-design principles. “Researchers asked 43 freelance developers to code the user registration for a web app and assessed how they implemented password storage. 26 devs initially chose to leave passwords as plaintext ” (via)
