Notes about Cutting-Edge Technologies and Everything

To gather insights on the current and future state of open source software (OSS), we talked to 31 executives. This is nearly double the number we speak to for a research guide and believe this reiterates the popularity of, acceptance of, and demand for OSS. We began by asking, "What Open Source software do you use?" As you would expect, most respondents are using several versions of open source software.

Here’s the run down of the firmware issues Etsy had over 5 or so years. Intel and Samsung turned out to be the most reliable. https://laur.ie/blog/2015/06/ssds-a-gift-and-a-curse/    The issue raised by Algolia is due to a Linux kernel error https://blog.algolia.com/when-solid-state-drives-are-not-that-solid/
