The obligatory disclaimer: The more performance you gain, the more data integrity you loose! But if you want to tune something like a file system, I strongly assume that you know what you are doing :) These tips apply to all major Linux distributions like Fedora/Red Hat, OpenSUSE, and Ubuntu that are already using ext4 or are going to make ext4 their default file system. As write operations on Solid State Disks (SSD) are expensive the tips below are focused on SSD usage but also apply to HDD usage as well .

Mozilla has seen better days. Once it offered a serious competitive threat to Microsoft’s Internet Explorer. Today, Mozilla’s Firefox squeaks into third place with just 12% market share of desktop browsers, according to NetMarketShare , and is worse than a rounding error among mobile browsers. Other projects, like Mozilla Thunderbird, are even less relevant. See also: What Mozilla’s WebAssembly Means: More Powerful Web Apps
When it comes to the Web's future, JavaScript creator Brendan Eich remains bullish on WebAssembly but also gives a thumbs-up to Service Worker technology. Speaking at the O'Reilly Fluent conference in San Francisco on Wednesday, Eich called WebAssembly the most exciting development he has seen in the past year. The project boosts Web performance by providing a portable code format to run in browsers at native speeds. Major browser vendors Apple, Google, Microsoft, and Mozilla all are on board with the effort.
