How to install MiniDLNA on Ubuntu Linux 14.04 LTS Trusty Tahr

When I was running Ubuntu Linux 12.04 LTS on my home server, I had installed minidlna as a media server that is accessible to DLNA capable clients, including a Smart TV where one can view photos on a large screen.

However, when the server was upgraded to 14.04 LTS, minidlna stopped working. Searching Google turned up forum posts from 2014 with instructions that no longer work.

Installing KDE Desktop on Ubuntu Server LTS 14.04

In mid June, my laptop hard disk died. Suddenly, there was a flurry of disk I/O wait, then applications started to report errors trying to write anything.

With a 500GB 2.5" laptop disk lying around that was used for backup, I replaced the dead disk with this one.

I had an Ubuntu Server 14.04 CD lying around, and therefore did not bother to download Kubuntu 14.04.

My laptop's home directory is backed up daily via ssh to the server. So my data was safe.

Avoiding changlog prompt when running aptitude full-upgrade

If you are, like me, an Ubuntu user who is annoyed when doing aptitude full-upgrade because it stops and displays the changelog until you press "q", then here is why this happens, and how to change the behavior.

The reason this happens is that the package apt-listchanges is installed on your system. This package lists the changes before applying them.

However, by default, it stops the upgrade process until the user has provided input. The silly part is that there are no choices at this point, the user must dismiss the output and nothing else can be done.

How to avoid PackageKit consuming lots of CPU and RAM on Kubuntu 14.04

After upgrading my laptop from Kubuntu 12.04 LTS to 14.04 LTS, I noticed that the laptop runs hotter than usual.

Upon investigating further, I found that PackageKit was the process that was consuming lots of CPU and memory.

For example, here is a sample output from htop, showing packagekitd maxing out one core, and eating up almost a quarter of the laptop's RAM:

How to install Firefox ESR on Ubuntu 64 bit LTS

To read my RSS feeds, I use Tiny Tiny RSS, which worked fine until 21 Feb 2014.

On 22 Feb 2014, Ubuntu pushed Firefox 27, Tiny Tiny RSS stopped working, with a Javascript error. After logging in, there would be a pop up error referring to getCookie and tracing to prototype.js.

To solve this, I went back to the ESR (Extended Support Release). This was quite a few steps, so I am documenting them here.

Solutions to Firefox using too much CPU on Ubuntu Linux

Ubuntu decided several months ago to forgo its policy of sticking with Firefox 3.6, and go with the latest versions from Mozilla.

With Firefox 13 running on Ubuntu 10.04, I had good performance, and did not suffer from this problem that I am about to describe. The only issue I faced was excessive disk activity and that was fixed by disabling the FireBug extension. Other than that, Firefox was speedy and responsive.

Converting Cisco Easy VPN .pcf files to Linux vpnc configuration format

Since I use Linux exclusively, and have to interface with clients using various Windows technologies, open standards are an important aspect of our tech-life. For example, we use OpenOffice to read Word/Excel/Powerpoint files, and so on.

One thing that comes infrequently is the need to login to a corporate virtual private network (VPN) that uses Cisco's Easy VPN.
