    Here are some neat neutrino facts:

    • Neutrinos are incredibly difficult to detect.
    • There are many neutrino sources, although supernovae may be the most prevalent with 99% of energy released as neutrinos vs 1% as visible light.
    • Our sun radiates about 2% of its energy as neutrinos.
    • They travel at the speed of light and rarely interact with normal matter. So rarely, in fact, that 99.99% of neutrinos would pass through a 10km-thick slab of lead.
    • Most neutrinos pass through the entire earth without hitting a thing.
    • 1021 nuetrinos pass through each 1" x 1" area of your body per second and, on average, you have a 25% lifetime chance of interaction with a neutrino particle.

    Who knows what will be discovered!




  • Also keep in mind that employees of companies that release closed source software are obligated to keep secret any gaping security vulnerabilities. This obligation usually comes with heavy legal ramifications that could be considered “life ruining” for many of us. e.g. Loss of your job plus a lawsuit.

    Often, none of the contributors to open source software are associated with each other and therefore have no obligation to keep discovered vulnerabilities a secret. In fact, I would assume that many contributors also actively use the software and have a personal interest in getting security vulnerabilities fixed.
