Installing Tamil fonts in Rosa Linux, Mandriva

As I was using Debian based flavours and redhat based Flavours I did not find any difficult in Installing fonts. As I have switched my home PC to Rosa linux R8.1 I was finding it difficult to Install tamil fonts. I have searched in Internet then I got to know about installing language. Below is to check whether the language exists

urpmq -a fonts-ttf-tamil

After checking this Exists then install using the below command

urpmi fonts-ttf-tamil

Once done you will see the language enabled in the browser.

Thank You


Beautify your terminal with screenFetch which is a Info tool

I have recently installed opensuse 42.2 gnome and making some changes. The changes were more about visual so I changed default theme as red arc theme and vivacious Icon theme then I changed color schemes in terminal and while searching I came accross this screenfetch.

Below is the screenshot



How to uninstall linux from windows in dual boot

First download bootsect.exe into the Download directory.

press the windows key, type cmd.exe and on the result (The command prompt) start it as an “Administrator” by right clicking on the cmd icon, and select Run as Administrator.

In the new cmd.exe window, cd to your download directory. for example cd C:\Users\Lalu Patel\Downloads. _assuming your user name is “Lalu Patel”.

Then enter this command. bootsect.exe /nt60 ALL /force /mbr. Restart your system to see that, Windows is automatically loading without grub.

Then in Windows

  1. Open the Control Panel (All Items view), and click on the Administrative Tools icon. then close the Control Panel window
  2. Click on Computer Management in Administrative Tools, then close the Administrative Tools window.
  3. In the left pane under Storage, click on Disk Management. see this.
  4. Select the the partition with unknown type. it is the Ubuntu partition. Right Click -> Delete partition.
  5. Now the former Ubuntu partition becomes an unallocated space.
  6. Select the left partition of the new unallocated space.
  7. Right click on the partition -> click on Extend Volume.
  8. Click on the Next button.
  9. Type in how many MB (1 GB = 1024 MB) you want to use from the unallocated space to extend the selected partition (step 5) into, then click on the Next button.see this.

    Note: If you want to use all of the unallocated space to extend into, then type in the maximum available space shown for the unallocated space.

  10. Click on the Finish button. You’re done.

Error while mounting NTFS file system as read write

Below is the error which comes when trying to mount NTFS file system with read and write access

The disk contains an unclean file system (0, 0).
Metadata kept in Windows cache, refused to mount.
Falling back to read-only mount because the NTFS partition is in an
unsafe state. Please resume and shutdown Windows fully (no hibernation
or fast restarting.)

After searching I got what to do

Run the below command

$ sudo ntfsfix /dev/sda8

Now mount the file system read and write access by below command

$ sudo mount -o rw /dev/sda8 /media/user


How To: Enable High Quality Audio in Linux

How To: Enable High Quality Audio in Linux

We can handle 96KHz 24-bit audio – but by default pulseaudio and alsa are configured for 44.1KHz 16-bit audio. At the 44.1/16-bit settings everything sounds great, but I figure if the quality can go higher and I’m not fussy about a bit of extra CPU usage then I may as well bump the quality settings up a bit to take full advantage. Here’s how to do it:

1 – Check current settings

To see what your current settings are, you can either run the following for the full details:

Or to cut to the sample rates directly use:

Depending on how many sound devices are connected you should see something like this (in my example I have an Intel HDA internal soundcard as the first sink, and HDMI audio out as the second sink):

You might want to play an mp3 at this point and then look at the pulseaudio cpu usage via the top command so you can compare the current and HQ CPU usage as it might be a factor for you (i.e. depending on the spec of your PC, you might not want to sacrifice 10% or more CPU usage for higher quality audio – but seeing as you’re here and reading this I’ll assume that you are!). As a baseline, with the default settings pulseaudio uses around 2-3% CPU to play an mp3 on my Intel i7.

2 – Modify for high quality

Pulseaudio’s global settings are stored in /etc/pulse/daemon.conf, so edit that with your editor of choice and look for the following lines (the ‘resample-method’ line is above the default-sample-* lines btw – that is, they’re not all together as below):

These are the defaults, and are currently commented out (you can use either ; or # to indicate a comment). Uncomment each line and modify it to the below (or even better – just add an uncommented line below each one so you can still see the default values), so you end up with:

The Arch Audiophile Playback wiki recommends medium quality for resampling, you might want to try src-sinc-best-quality if you’re going for broke. A description of the libsamplerate resampling methods can be found here if you’re interested:

I get about 10% CPU usage on the pulseaudio daemon with 96KHz @ 24-bit audio with medium quality resampling as above, whilst using src-sinc-best-quality results in a rather significant 24% CPU usage just to play an mp3! ( It’s like having a Pentium 100MHz all over again! 😉 ) The ‘s24le’ means 24-bit samples, little-endian order, btw.

3 – Restart pulseaudio and check the settings

Now that’s done we need to restart the pulseaudio daemon (don’t run these as sudo – pulseaudio runs per user so just execute as normal!):

Once that’s done, you should be able to check the settings have taken by issuing:

It’s jumped up to 32-bit samples in this case, but that’s fine. Check the audio still works, and maybe have a look at the CPU usage when playing an mp3 via top again if you want to see how much this is affecting the CPU usage on your machine.

FiiO E17 Amp Check

Now that we’ve set higher quality default settings, if you’ve got some suitable hardware for them like the above-mentioned amp, plug that bad-boy in, switch it on – and it should validate that it’s getting the higher sample-rate and sample-depth:

Fiio E17 at 96KHz 24-bit via pulseaudio via USB (i.e. it’s acting as a sound card). The ’40’ value is just the current volume setting.

Sound Quality Differences

So – does changing these audio setting make a definite, perceivable difference to the audio quality? The short answer is yes!

How much it changes the audio quality is going to depend on your hardware (amp, headphones etc.) as well as the actual audio file(s) you’re playing on it. I don’t have any 24-bit audio to try it out on, but I rip everything at the highest possible quality VBR mp3s using lame – so I’ve been testing on the first track of Alt-J’s album (intro) with some Sennheiser HD650’s – and my honest answer? I’d go as far as to say it’s a strong yes (html joke ;-)). The high-frequency elements in particular seem a little brighter with the 96KHz 24-bit sampling, at least when run through the FiiO E17. Now, this could be placebo – that is, you expect something to sound different/react in a particular way so you look for it and (internally, subconciously) try to convince yourself of it. But I’ve honestly swapped back and forth and listed to the same track a number of times during the writing of this article and I genuinely believe it’s sounding better with the HQ settings.

Unfortunately, the schoolboy error I’ve made here is that I’ve changed two (if not three!) things at once: I’ve enabled the higher sampling-rate and sample-size/depth, but I’ve also modified the resampling algorithm to one of higher quality at the same time – so figuring out what elements of the audio sound better because of the audio settings and which are from the resampling-method (because I’m not playing native 96KHz @ 24-bit audio files to test with) can’t really be done. To get any real results I’d need to strip back to default settings and modify each in turn, doing listening tests with notes as I go, which frankly isn’t all that high up there on my priority list of things to do because…


…I’m delighted with the audio quality after these changes! It really does sound great =D

Ideally, I’d prefer to have things set to 44.1KHz on each audio device EXCEPT the Fiio – that way, when I’m playing games there’s minimal CPU used on the audio side (which isn’t really going to benefit that much from upsampling and such, I’d imagine) and then have the HQ settings for the FiiO only so that when I plug it to listen to music I get the HQ audiophile kick. However, my understanding is that I’d need to go into the alsa side of things to configure device specific settings – and again, it’s not really a high priority at the moment.

I’d love to hear what difference (or lack thereof!) any of you find when changing over to HQ audio (asides from the bump in CPU usage) – and if you run or have played with different samplerate/re-sample settings for diff devices I’d be especially interested! Cheers!

Installing fedora tool groups in fedora 23

In fedora they have grouped packages according the needs like for an example if a person is interested in he has to download a distribution or he has to get a fedora lab of his choice for example Audio Editing or he can go for some other distro which has Audio Editing  tools and now he is also interested in security tools so he has to search all the tools and then he will install with audio editing tools. So to simplify this fedora provides group. So there are many groups users can get specialized tools in the groups.

Now type the below command to search the list of groups in fedora

$ dnf groups list

Now Install the needed group to your system by firing the below command

# dnf groups install “Security Lab”

Note: this command will not support the versions below fedora 21



Changing the Prefix key of Tmux(Terminal Multiplexer)

Edit the file tmux.conf If it is a new Installation you will not have this file so create a new file in home directory by firing the below command

vi ~/.tmux.conf

Now enter the three lines for changing the default Ctrl-b to ` symbol as prefix key

unbind C-b

set-option -g prefix ‘`’

bind-key ‘`’ send-prefix

For this change to happen for all users write the config file to /etc folder so resulting your tmux file will be in /etc/tmux.conf


GNOME Workstation OS

ME is being maintained by a skeleton crew, and a shrinking set of corporate stakeholders. I think it is time to be realistic about what we could excel at, and go there. We don’t have to be on every existing form factor to achieve world domination. The cloud, and all these cheap new gadgets have lowered the barrier to access. We could lower the barrier of autho
