How I make my Ubuntu 16.04 boot 34 seconds faster?

I recently thought about the booting speed of my Ubuntu. Below is what I did step by step.

At first, I checked the boot time with
systemd-analyze

I got something around 1 min 19.281s.

So, I did

systemd-analyze blame

I checked the list and thought about removing mysql and postgres. After removing both of them completely I got around 30 seconds faster booting.

Not only this, I edited the grub configuration. Β I removed the plymouth boot screen and switched to basic command line interface for both grub boot menu and booting progress.

Also, you can enable the driver profiling. Restart and remove the driver profiling.

Β 

sudo vim /etc/default/grub

Check this file it is pretty simple. If you want some more explanation comment below. I will update this later.

Note: Don’t forget to run

sudo update-grub2

after you edit the /etc/default/grub file.

Thats all for today. Thanks.

Using cmus, a command line music player

Hello.

cmus is a command line music player.

It is very easy to use. If you have some experience with vim, that would be great.

Best way to learn using cmus is :

$ man cmus-tutorial

 

Everything is there.

Update:

Userful keys:

v – stop playback

b – next track

z – previous track

c – pause playback

s – toggle shuffle

m – switch between artist/album/all playlist

x – restart

/ – searching like in vim

– reduce 10% volume

+ – increase 10% volume

Hello there. I am learning BDD with Cucumber. I have following problem. If someone can help that would be great.

show_blog_list.feature
Feature: Show blog list
As a blog visitor
I can see list of posted blogs

Scenario: Show blog list
Given there are already 4 posts
And I am on the blog homepage
Then I can see list of 4 posted blogs

Then /^I can see list of (\d) posted blogs$/ do |count|
page.should have_selector (“table#posts-list>tr:eq(#{count})”)
end

count.to_i.times do |n|
Post.create!({ :title => “Title #{n}”, :content =>
“Content #{n}”, :post_time => Time.now })
