November 18, 2017 / / Antergos

I moved to Antergos, an Arch Linux distribution. For the last 10 years I was using Ubuntu and very much used to it. I got bored and looking for a new Linux distribution. My colleague suggested Arch Linux as it is lean and does not come with baggage of unnecessary applications. Installing Arch Linux is a tedious task as it does not come with an user friendly installer as we have for Ubuntu. It is well known in the community that Arch is for serious Linux enthusiasts. I found Antergos over the Internet and thought of giving it a try.  Believe me, it is really awesome. I am using it for the last 3 months and really loving it.

Qt Charts which are available only under commercial license was now opensource according to Qt Blog. This is a great oppurtunity for us as our client who is a semiconductor company relies on Qt for his System on Chip (SoC) software. We built performance dashboards for their FPGA boards using Qt Embedded. Performance dashboards need graphs to preset their statistics for CPU, frequency etc. Weuse scatter plot, line chart, bar chart etc.
