Watch These Kids Having Fun With Linux Terminal In Ubuntu
|
||||
================================================================================
|
||||
I found this short video of children having fun with Linux terminals in their computer lab at school. I do not know where do they belong to, but I guess it is either in Indonesia or Malaysia.

||||

### Run train in Linux terminal ###
|
||||
|
||||
There is no magic here. It’s just a small command line fun tool called ‘sl’. I presume that it was developed entirely to have some fun when command ls is wrongly typed. If you ever worked on Linux terminal, you know that ls is one of the most commonly used commands and perhaps one of the most frequently mis-typed command as well.
|
||||
|
||||
If you want to have little fun with this terminal train, you can install it using the following command:
|
||||
|
||||
sudo apt-get install sl
|
||||
|
||||
To run the terminal train, just type **sl** in the terminal. It also has the following options:
|
||||
|
||||
- -a : Accident mode. You can see people crying help
|
||||
- -l : shows a smaller train but with more coaches
|
||||
- -F : A flying train
|
||||
- -e : Allows interrupt by Ctrl+C. In other mode you cannot use Ctrl+C to stop the train. But then, it doesn’t run for long.
|
||||
|
||||
Normally, you should hear the whistle as well but it doesn’t work in most of the Linux OS, Ubuntu 14.04 being one of them. Here is the accidental terminal train :)

Fix No Bootable Device Found Error After Installing Ubuntu
|
||||
================================================================================
|
||||
Usually, I dual boot Ubuntu and Windows but this time I decided to go for a clean Ubuntu installation i.e. eliminating Windows completely. After the clean install of Ubuntu, I ended up with a screen saying **no bootable device found** instead of the Grub screen. Clearly, the installation messed up with the UEFI boot settings.
|
||||
|
||||
|
||||
|
||||
I am going to show you how I fixed **no bootable device found error after installing Ubuntu in Acer laptops**. It is important that I mention that I am using Acer Aspire R13 because we have to change things in firmware settings and those settings might look different from manufacturer to manufacturer and from device to device.
|
||||
|
||||
So before you go on trying the steps mentioned here, let’s first see what state my computer was in during this error:
|
||||
|
||||
- My Acer Aspire R13 came preinstalled with Windows 8.1 and with UEFI boot manager
|
||||
- Secure boot was not turned off (my laptop has just come from repair and the service guy had put the secure boot on again, I did not know until I ran up in the problem). You can read this post to know [how disable secure boot in Acer laptops][1]
|
||||
- I chose to install Ubuntu by erasing everything i.e. existing Windows 8.1, various partitions etc.
|
||||
- After installing Ubuntu, I saw no bootable device found error while booting from the hard disk. Booting from live USB worked just fine
|
||||
|
||||
In my opinion, not disabling the secure boot was the reason of this error. However, I have no data to backup my claim. It is just a hunch. Interestingly, dual booting Windows and Linux often ends up in common Grub issues like these two:
|
||||
|
||||
- [error: no such partition grub rescue][2]
|
||||
- [Minimal BASH like line editing is supported][3]
|
||||
|
||||
If you are in similar situation, you can try the fix which worked for me.
|
||||
|
||||
### Fix no bootable device found error after installing Ubuntu ###
|
||||
|
||||
Pardon me for poor quality images. My OnePlus camera seems to be not very happy with my laptop screen.
|
||||
|
||||
#### Step 1 ####
|
||||
|
||||
Turn the power off and boot into boot settings. I had to press Fn+F2 (to press F2 key) on Acer Aspire R13 quickly. You have to be very quick with it if you are using SSD hard disk because SSDs are very fast in booting. Depending upon your manufacturer/model, you might need to use Del or F10 or F12 keys.
|
||||
|
||||
#### Step 2 ####
|
||||
|
||||
In the boot settings, make sure that Secure Boot is turned on. It should be under the Boot tab.
|
||||
|
||||
#### Step 3 ####
|
||||
|
||||
Go to Security tab and look for “Select an UEFI file as trusted for executing” and click enter.
|
||||
|
||||
|
||||
|
||||
Just for your information, what we are going to do here is to add the UEFI settings file (it was generated while Ubuntu installation) among the trusted UEFI boots in your device. If you remember, UEFI boot’s main aim is to provide security and since Secure Boot was not disabled (perhaps) the device did not intend to boot from the newly installed OS. Adding it as trusted, kind of whitelisting, will let the device boot from the Ubuntu UEFI file.
|
||||
|
||||
#### Step 4 ####
|
||||
|
||||
You should see your hard disk like HDD0 etc here. If you have more than one hard disk, I hope you remember where did you install Ubuntu. Press Enter here as well.
|
||||
|
||||
|
||||
|
||||
#### Step 5 ####
|
||||
|
||||
You should see <EFI> here. Press enter.
|
||||
|
||||
|
||||
|
||||
#### Step 6 ####
|
||||
|
||||
You’ll see <Ubuntu> in next screen. Don’t get impatient, you are almost there
|
||||
|
||||
|
||||
|
||||
#### Step 7 ####
|
||||
|
||||
You’ll see shimx64.efi, grubx64.efi and MokManager.efi file here. The important one is shimx64.efi here. Select it and click enter.
|
||||
|
||||
|
||||
|
||||
|
||||
In next screen, type Yes and click enter.
|
||||
|
||||
|
||||
|
||||
#### Step 8 ####
|
||||
|
||||
Once we have added it as trused EFI file to be executed, press F10 to save and exit.
|
||||
|
||||
|
||||
|
||||
Reboot your system and this time you should be seeing the familiar Grub screen. Even if you do not see Grub screen, you should at least not be seeing “no bootable device found” screen anymore. You should be able to boot into Ubuntu.
|
||||
|
||||
If your Grub screen was messed up after the fix but you got to login into it, you can reinstall Grub to boot into the familiar purple Grub screen of Ubuntu.
|
||||
|
||||
I hope this tutorial helped you to fix no bootable device found error. Any questions or suggestions or a word of thanks is always welcomed.

How To Add Hindi And Devanagari Support In Antergos And Arch Linux
|
||||
================================================================================
|
||||
|
||||
|
||||
You might be knowing by now that I have been trying my hands on [Antergos Linux][1] lately. One of the first few things I noticed after installing [Antergos][2] was that **Hindi scripts were not displayed properly** in the default chromium browser.
|
||||
|
||||
This is a strange thing that I never encountered before in my desktop Linux experience ever. First, I thought maybe it could be a browser problem so I went on to install Firefox only to see the same story repeated. Firefox also could not display Hindi properly. Unlike Chromium that displayed nothing, Firefox did display something but it was not readable.
|
||||
|
||||
|
||||
|
||||
Hindi display in Chromium
|
||||
|
||||
|
||||
|
||||
Hindi display in Firefox
|
||||
|
||||
Strange? So no Hindi support in Arch based Antergos Linux by default? I did not verify, but I presume that it would be the same for other Indian languages etc that are also based on Devanagari script.
|
||||
|
||||
I this quick tutorial, I am going to show you how to add Devanagari support so that Hindi and other Indian languages are displayed properly.
|
||||
|
||||
### Add Indian language support in Antergos and Arch Linux ###
|
||||
|
||||
Open a terminal and use the following command:
|
||||
|
||||
sudo yaourt -S ttf-indic-otf
|
||||
|
||||
Enter the password. And it will provide rendering support for Indian languages.
|
||||
|
||||
Restarting Firefox displayed Hindi correctly immediately, but it took a restart to display Hindi. For that reason, I advise that you **restart your system** after installing the Indian fonts.
|
||||
|
||||
|
||||
|
||||
I hope tis quick helped you to read Hindi, Sanskrit, Tamil, Telugu, Malayalam, Bangla and other Indian languages in Antergos and other Arch based Linux distros such as Manjaro Linux.

How to Setup Zephyr Test Management Tool on CentOS 7.x
|
||||
================================================================================
|
||||
Test Management encompasses anything and everything that you need to do as testers. Test management tools are used to store information on how testing is to be done, plan testing activities and report the status of quality assurance activities. So in this article we will illustrate you about the setup of Zephyr test management tool that includes everything needed to manage the test process can save testers hassle of installing separate applications that are necessary for the testing process. Once you have done with its setup you will be able to track bugs, defects and allows the project tasks for collaboration with your team as you can easily share and access the data across multiple project teams for communication and collaboration throughout the testing process.
|
||||
|
||||
### Requirements for Zephyr ###
|
||||
|
||||
We are going to install and run Zephyr under the following set of its minimum resources. Resources can be enhanced as per your infrastructure requirements. We will be installing Zephyr on the CentOS-7 64-bit while its binary distributions are available for almost all Linux operating systems.
|
||||
|
||||

</table>
|
||||
|
||||
You must have super user (root) access to perform the installation process for Zephyr and make sure that you have properly configured yout network with static IP address and its default set of ports must be available and allowed in the firewall where as the Port 80/443, 8005, 8009, 8010 will used by tomcat and Port 443 or 2099 will used within Zephyr by flex for the RTMP protocol.
|
||||
|
||||
### Install Java JDK 7 ###
|
||||
|
||||
Java JDK 7 is the basic requirement for the installation of Zephyr, if its not already installed in your operating system then do the following to install Java and setup its JAVA_HOME environment variables to be properly configured.
|
||||
|
||||
Let’s issue the below commands to install Java JDK 7.
|
||||
|
||||
[root@centos-007 ~]# yum install java-1.7.0-openjdk-1.7.0.79-2.5.5.2.el7_1
|
||||
|
||||
----------
|
||||
|
||||
[root@centos-007 ~]# yum install java-1.7.0-openjdk-devel-1.7.0.85-2.6.1.2.el7_1.x86_64
|
||||
|
||||
Once your java is installed including its required dependencies, run the following commands to set its JAVA_HOME environment variables.
|
||||
|
||||
[root@centos-007 ~]# export JAVA_HOME=/usr/java/default
|
||||
[root@centos-007 ~]# export PATH=/usr/java/default/bin:$PATH
|
||||
|
||||
Now check the version of java to verify its installation with following command.
|
||||
|
||||
[root@centos-007 ~]# java –version
|
||||
|
||||
----------
|
||||
|
||||
java version "1.7.0_79"
|
||||
OpenJDK Runtime Environment (rhel-2.5.5.2.el7_1-x86_64 u79-b14)
|
||||
OpenJDK 64-Bit Server VM (build 24.79-b02, mixed mode)
|
||||
|
||||
The output shows that we we have successfully installed OpenJDK Java verion 1.7.0_79.
|
||||
|
||||
### Install MySQL 5.6.X ###
|
||||
|
||||
If you have other MySQLs on the machine then it is recommended to remove them and
|
||||
install this version on top of them or upgrade their schemas to what is specified. As this specific major/minor (5.6.X) version of MySQL is required with the root username as a prerequisite of Zephyr.
|
||||
|
||||
To install MySQL 5.6 on CentOS-7.1 lets do the following steps:
|
||||
|
||||
Download the rpm package, which will create a yum repo file for MySQL Server installation.
|
||||
|
||||
[root@centos-007 ~]# yum install wget
|
||||
[root@centos-007 ~]# wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
|
||||
|
||||
Now Install this downloaded rpm package by using rpm command.
|
||||
|
||||
[root@centos-007 ~]# rpm -ivh mysql-community-release-el7-5.noarch.rpm
|
||||
|
||||
After the installation of this package you will get two new yum repo related to MySQL. Then by using yum command, now we will install MySQL Server 5.6 and all dependencies will be installed itself.
|
||||
|
||||
[root@centos-007 ~]# yum install mysql-server
|
||||
|
||||
Once the installation process completes, run the following commands to start mysqld services and check its status whether its active or not.
|
||||
|
||||
[root@centos-007 ~]# service mysqld start
|
||||
[root@centos-007 ~]# service mysqld status
|
||||
|
||||
On fresh installation of MySQL Server. The MySQL root user password is blank.
|
||||
For good security practice, we should reset the password MySQL root user.
|
||||
|
||||
Connect to MySQL using the auto-generated empty password and change the
|
||||
root password.
|
||||
|
||||
[root@centos-007 ~]# mysql
|
||||
mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('your_password');
|
||||
mysql> flush privileges;
|
||||
mysql> quit;
|
||||
|
||||
Now we need to configure the required database parameters in the default configuration file of MySQL. Let's open its file located in "/etc/" folder and update it as follow.
|
||||
|
||||
[root@centos-007 ~]# vi /etc/my.cnf
|
||||
|
||||
----------
|
||||
|
||||
[mysqld]
|
||||
datadir=/var/lib/mysql
|
||||
socket=/var/lib/mysql/mysql.sock
|
||||
symbolic-links=0
|
||||
|
||||
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
|
||||
max_allowed_packet=150M
|
||||
max_connections=600
|
||||
default-storage-engine=INNODB
|
||||
character-set-server=utf8
|
||||
collation-server=utf8_unicode_ci
|
||||
|
||||
[mysqld_safe]
|
||||
log-error=/var/log/mysqld.log
|
||||
pid-file=/var/run/mysqld/mysqld.pid
|
||||
default-storage-engine=INNODB
|
||||
character-set-server=utf8
|
||||
collation-server=utf8_unicode_ci
|
||||
|
||||
[mysql]
|
||||
max_allowed_packet = 150M
|
||||
[mysqldump]
|
||||
quick
|
||||
|
||||
Save the changes made in the configuration file and restart mysql services.
|
||||
|
||||
[root@centos-007 ~]# service mysqld restart
|
||||
|
||||
### Download Zephyr Installation Package ###
|
||||
|
||||
We done with installation of required packages necessary to install Zephyr. Now we need to get the binary distributed package of Zephyr and its license key. Go to official download link of Zephyr that is http://download.yourzephyr.com/linux/download.php give your email ID and click to download.
|
||||
|
||||
|
||||
|
||||
Then and confirm your mentioned Email Address and you will get the Zephyr Download link and its License Key link. So click on the provided links and choose the appropriate version of your Operating system to download the binary installation package and its license file to the server.
|
||||
|
||||
We have placed it in the home directory and modify its permissions to make it executable.
|
||||
|
||||
|
||||
|
||||
### Start Zephyr Installation and Configuration ###
|
||||
|
||||
Now we are ready to start the installation of Zephyr by executing its binary installation script as below.
|
||||
|
||||
[root@centos-007 ~]# ./zephyr_4_7_9213_linux_setup.sh –c
|
||||
|
||||
Once you run the above command, it will check for the Java environment variables to be properly setup and configured. If there's some mis-configuration you might the error like.
|
||||
|
||||
testing JVM in /usr ...
|
||||
Starting Installer ...
|
||||
Error : Either JDK is not found at expected locations or JDK version is mismatched.
|
||||
Zephyr requires Oracle Java Development Kit (JDK) version 1.7 or higher.
|
||||
|
||||
Once you have properly configured your Java, then it will start installation of Zephyr and asks to press "o" to proceed and "c" to cancel the setup. Let's type "o" and press "Enter" key to start installation.
|
||||
|
||||
|
||||
|
||||
The next option is to review all the requirements for the Zephyr setup and Press "Enter" to move forward to next option.
|
||||
|
||||
|
||||
|
||||
To accept the license agreement type "1" and Press Enter.
|
||||
|
||||
I accept the terms of this license agreement [1], I do not accept the terms of this license agreement [2, Enter]
|
||||
|
||||
Here we need to choose the appropriate destination location where we want to install the zephyr and choose the default ports, if you want to choose other than default ports, you are free to mention here.
|
||||
|
||||
|
||||
|
||||
Then customize the mysql database parameters and give the right paths to the configurations file. You might the an error at this point as shown below.
|
||||
|
||||
Please update MySQL configuration. Configuration parameter max_connection should be at least 500 (max_connection = 500) and max_allowed_packet should be at least 50MB (max_allowed_packet = 50M).
|
||||
|
||||
To overcome this error make sure that you have configure the "max_connection" and "max_allowed_packet" limits properly in the mysql configuration file. So confirm these settings, connect to mysql server and run the commands as shown.
|
||||
|
||||
|
||||
|
||||
Once you have configured your mysql database properly, it will extract the configuration files to complete the setup.
|
||||
|
||||
|
||||
|
||||
The installation process completes with successful installation of Zephyr 4.7 on your computer. To Launch Zephyr Desktop type "y" to finish Zephyr installation.
|
||||
|
||||
|
||||
|
||||
### Launch Zephyr Desktop ###
|
||||
|
||||
Open your web browser to launch Zephyr Desktop with your localhost IP adress and you will be direted to the Zephyr Desktop.
|
||||
|
||||
http://your_server_IP/zephyr/desktop/
|
||||
|
||||
|
||||
|
||||
From your Zephyr Dashboard click on the "Test Manager" and login with the dault user name and password that is "test.manager".
|
||||
|
||||
|
||||
|
||||
Once you are loged in you will be able to configure your administrative settings as shown. So choose the settings you wish to put according to your environment.
|
||||
|
||||
|
||||
|
||||
Save the settings after you have done with your administrative settings, similarly do the settings of resources management and project setup and start using Zephyr as a complete set of your testing management tool. You check and edit the status of your administrative settings from the Department Dashboard Management as shown.
|
||||
|
||||
|
||||
|
||||
### Conclusion ###
|
||||
|
||||
Cheers! we have done with the complete setup of Zephyr installation setup on Centos 7.1. We hope you are now much aware of Zephyr Test management tool which offer the prospect of streamlining the testing process and allow quick access to data analysis, collaborative tools and easy communication across multiple project teams. Feel free to comment us if you find any difficulty while you are doing it in your environment.
