XMPP (Extensible Messaging Presence Protocol) is a decentralized model of network to facilitate instant messaging and collaboration. Decentralize means there is no central server that has access to your data. The communication is directly between the end-points.

Some of us might call it an “old school” tech probably because the XMPP clients usually have a very bad user experience or simply just because it takes time to get used to (or set it up). That’s when Dino comes to the rescue as a modern XMPP client to provide a clean and snappy user experience without compromising your privacy.

Storage benchmarking—much like Wi-Fi benchmarking—is a widely misunderstood black art. Admins and enthusiasts have for decades been tempted to just “get the big number” by reading or writing a large amount of data to a disk, getting a figure in MB/sec, and calling it a day. Unfortunately, the actual workload of a typical disk doesn’t look like that—and that “simple speed test” doesn’t reproduce a lot of the bottlenecks that slow down disk access in real-world systems.

The most realistic way to test and benchmark disks is, of course, to just use them and see what happens. Unfortunately, that’s neither very repeatable, nor is it simple to analyze. So we do want an artificial benchmarking tool—but we want one that we can use intelligently to test storage systems across realistic scenarios that model our day-to-day usage well. Fortunately, we don’t have to invent such a tool—there’s already a free and open source software tool called fio, and it’s even cross-platform!
