As the long-term evolution (LTE) system embracing 4G is reaching maturity, it is reasonable for humanity to ponder “what’s next?”
We all know that 5G is a paradigm shift from 4G with very high carrier frequencies, massive bandwidths, a tremendous amount of base station and device densities, and unprecedented numbers of antennas.
Linux often gets a bad reputation when it comes to installing software, and this is because we have so many different application distribution formats. Most of them also are misunderstood, or have preconceived notions attached to them, so I think it’s time to take a look at the differences among the different packaging formats!
When you realize your system is getting slow and is unable to handle the current number of requests even with optimizations, you need to scale the system sooner than you can optimize further. Building a scalable system also drives to a lower Total Cost of Ownership (TCO). Proper scaling in process-intensive applications embraces interesting new scenarios, notably in data analytics and machine learning.
Wait, What is Docker? Have you ever worried about software running in your machine but not in other systems? Docker is the solution. Docker sandboxes applications running within as containers so that their execution is completely isolated from others. This has become enormously popular over the last few years, but to capitalize on it, you need to integrate third-party images.
Even though the Raspberry Pi comes with an HDMI port, most projects are headless (runs without a display), which suggests you’re mostly using SSH to access the system. I’m bored of seeing the most basic login banner with no information. This login banner is your MOTD (Message of the day, Linux term).
