High-speed Internet from space: The Starlink network

SatelliteAccessing the Internet from space is not new, with many companies (OneWeb, Space Norway, Telesat, etc.) now offering it. More recently, however, a new participant has emerged on the scene promising something different – Starlink. SpaceX’s plan is to create a network of 12,000 satellites that fly from 350 to 1160 km above our heads and provide fast Internet access using lasers.

Robot Framework and test automation

Robot FrameworkProcess automation is becoming increasingly important when developing new software and hardware, as a means to detect implementation failures, carry out behavioral tests involving resources and scenarios, etc. On top of saving employees a great amount of time, it is a quick and easy method that is highly reliable when compared to the alternative: specific tests that have to be run manually. As a result, well-known and highly effective infrastructures (like Robot Framework) have been created.

Open Source Software Licenses

OPEN SOURCE CONCEPT

A few weeks ago I wrote a post on the Teldat blog about open source software. I explained how we were seeing the tremendous growth in the use of open source software in recent years. So much so, that the top acquisitions within the technology sector in last year have been for open source software. In that post, I gave an explanation of the advantages and disadvantages to using open source software in comparison to proprietary software or closed source software. However, as I explained then, the trends all indicate that the open source software market is going to increase at a fast rate, hence I have decided to write a new post in order to go one step deeper into this market and explain the important role that licenses play within these types of software and the main differences between them.

Open Source or Proprietary software?

Open sourceOpen source software landed more than thirty years ago, but over the past few years we have seen a tremendous growth in the open source software community, taking a stronger hold in the market in comparison to proprietary software (closed source software). Indeed, before proprietary software was a clear leader. However, the tendency is changing, as more and more CIO’s and CTO’s are moving towards open source. During 2018 we have seen many of the world’s top software companies recognize this phenomenon and have directly acquired various major open source companies. Some of the acquisitions announced last year were huge and were even placed in the top ten acquisitions ever made in the technology sector.
