At last, I am now on Fedora 25. It’s great to again be able to use VLC and TexStudio without having to do use any workarounds! Still need to test the Optimus improvements but can’t seem to be able to get Nvidia module to start. bbswitch is loaded. Need some time to figure this one out. I guess will have to try Dota 2 7.00 on WinDoze. Edit: It now works perfectly.

Toured Seville today thanks to https://www.feelthecitytours.com/en/tours/sevilla/ . They are an amazing company with a great tour of this beautiful city. Got to learn a lot about the city along with a bunch of great stories about the city. One of them was the story of Carmen (http://www.geocities.jp/wakaru_opera/englishcarmen.html) which is a pretty nice story. The TAC meeting was pretty nice and was followed by the TAC team dinner at a Tapas restaurant.

Reached the Melia Sevilla, Spain tonight. Pretty excited about ApacheCon. Am planning on finalizing the presentations about Allura by tomorrow night and discuss them with @brondsem on Monday. It was a long trip to Sevilla via Madrid and London with @gauravsaini03, he will be speaking about Apache OFBiz which is a complete enterprise solution. Met Dr Paul King(@paulk_asert), who is working on Apache Groovy and has worked on the “Groovy in Action” book by Manning publications.

I’m excited about attending ApacheCon Big Data and ApacheCon 16 at Seville, Spain. Only a few days are left. Talked with my mentor at Apache Allura, @brondsem today about his experiences at ApacheCon NA Denver 14 and what all I could do at ACEU 16. We’re hoping for improving the exposure of Apache Allura within the Apache community and trying to get some projects in the incubator to try Allura. I’ll try to present a lightning talk and host a demo session for Allura at the conference.

A tip on using fsck

Permalink 1 minute read Modified: (rhnvrm)

A tip on using fsck when you are stuck in emergency mode. Whenever you are using `fsck -y` and it does not allow you to run because a certain device (say /dev/sdaX) is mounted, it does not mean you can’t run `fsck -y /dev/sdaY`. That is you don’t unmount that device.

Just installed a new theme for the blog called P2. I’m using a child theme called Mercury. Also installed and played with a bunch of plugins. Want to try micro blogging and also live blogging during my coding sessions. Also, learnt that AJAX requests don’t seem to work behind proxies. P2 sends an initial Ajax request when you click on post from the front-end and it was failing, scourged the internet but couldn’t find a solution.

Hello WordPress

I’m back to using WordPress from Jekyll. I followed David Lynch’s blog post to import my posts from the jekyll blog hosted on github.io Although, I did not use the plugins made by him, they might be useful if you had a lot of Disqus comments in your blog.

Topological Sort for problems using DAG

Permalink 3 minute read Modified: (rhnvrm)

Given a DAG (Directed Acyclic Graph), in which we know the adjacencies represent the order in which to perform a task, and the vertices are tasks, we want to place the vertices in a sequence. We must find a sequence that must satisfy all dependencies of pre-requisites. This sequential arrangement of the vertices is called the topological sort of the DAG. The first examples that come in my mind are of pre-requisite chains in courses offered at universities.
