Creating presentations with Org mode

As I said in the last blog post about Emacs, I use Org mode a lot. It’s the default mode I use for taking notes, tracking tasks etc. The export interface it provides is a really useful feature. There are a lot of packages, which provide ways to export the Org mode file to other formats like Markdown in addition to default supported formats HTML, PDF, text etc. Presenting within Emacs A few months ago I had a talk on Autoscaling in Kubernetes within our company.

Entering The Church of Emacs

From the title you may think this is another post or debate on <your favorite editor here> vs GNU Emacs. I will be talking about how I started using Emacs and why it is the best tool I have ever used. How it started During dgplug summer-training 2018, we had series of sessions on GNU Emacs. Thanks to mbuf, the whole series helped me a lot to get started with Emacs and now I use it for all my editing.

Where is bhavin192?

It’s been nearly a year since I have posted anything on my blog. So, where I was? I was planning to migrate this blog from the WordPress setup to a static site generator.

How to play Steam games on Fedora

In Steam Summer sale of 2017, I had bought Left 4 Dead 2 just for Rs. 64. I played it once or twice and after that never played it again, as it was installed on Windows.

Finding the data usage culprit [ packagekitd ]

Yesterday morning, I noticed that my laptop was using high bandwidth. It was nearly 1MBps. It was little bit suspicious for me. At first, I thought it must be Chrome, but later I realized Chrome does not auto update itself. Now the question is, who is using the data. One change I observed was after using that much amount of data, it stopped showing notification about update. This never happened before, so I thought it may be something related to updates.

Running Oracle database XE 11G using Docker

In our syllabus we have Advance Database Systems subject. We were instructed to use Oracle database for this.
