These strange questions came to the fore back in 2014 when Netflix was switching services from CentOS Linux to Ubuntu, and I helped debug several weird performance issues including one I'll describe here. Colleagues/Internet I love using [Linux performance tools]. This will slow this test a little.) How would you _time_ time?

Google made SSL use a ranking factor way back in 2014, and since Chrome 68, a “Not Secure” warning appears next to the URL of sites that aren’t using HTTPS. These types of intrusions can be very difficult to find and remove once in place. To be completely honest, you almost have to use it. Source: Google Blog.

The eye-tracking methodology can be extremely valuable for usability tests since it records the journey without interfering with the users’ natural behavior. Imagine, for example, that you test a prototype but discover that users are not interacting with the interface how they are supposed to. Mariana Macedo. 2021-10-27T10:00:00+00:00.

Defenders of Apple's monopoly offer hard-to-test claims, but many boil down to the idea that Apple's product is inferior by necessity. This will, in turn, cause developers to skimp on testing for Safari, making it inevitable that browsers based on WebKit and other minority engines cannot compete. Or so the theory goes.

Rules like those summarized in the Appendix would have prevented (at compile time, test time or run time) most of the past CVEs I’ve reviewed in the type, bounds, and initialization categories, and would have prevented many of the lifetime CVEs. Do configure your servers correctly, especially public Internet-facing ones.

This prevents bad practices like code duplication and simplifies unit testing by many miles. This can provide near native functionality and user experience while being able to function without an active internet connection. From MVC architecture to routers and data layers to testing tools, all is built into the application by default.

To provide some coherence to the music, I decided to use Taylor Swift songs since her discography covers the time span of most papers that I typically read: Her main albums were released in 2006, 2008, 2010, 2012, 2014, 2017, 2019, 2020, and 2022. This choice also inspired me to call my project Swift Papers.

We're now testing container hosts in production on btrfs, instead of ZFS. In a test environment, I've seen several more Linux panics in the past three years. The odd time we hit them, we'll take the "oops message" – a dump of the kernel stack trace and other details from the system log – and search the Internet.
