WinAero - very useful to customize Windows 10 font size, etc

Since the last major Window 10 updates, the old way to customize the icon font size went away. The closest way to make the Windows 10 desktop icon's font size bigger is through using Settings --> Display --> Advanced Custom Scaling. However, this does not yield the desired result, because it could end up increasing the size of fonts as well as icon size and everything else on the screen in proportion.

 I did a quick Google Search and found a utility called WinAero ( This tool allows granular customization of specific items, such as icon font and icon font size. On a 14-inch screen laptop with 1366x768 resolution, being able to use 11-point, semi-bold Segoe UI font makes it really nice to use the laptop again.

CentOS 6 - Set Static IP

In order to set static ip on CentOS 6:

  1. Open ifcfg-Auto_eth0 file at /etc/sysconfig/network-scripts folder
    1. sudo vi /etc/sysconfig/network-scripts/ifcfg-Auto_eth0
      1. The file name could be different. It could be ifcfg_eth0, too.
  2. Change the content to something like below:
    1. TYPE=Ethernet
  3. :wq
  4. Open resolv.conf and check or correct the nameserver
    1. sudo vi /etc/resolv.conf
    2. It should be like the following.
      1. nameserver
      2. nameserver
  5. Restart network
    1. sudo /etc/init.d/network restart

Other admins use /etc/sysconfig/network file to specify the default gateway. They may not specify DNS1 or DNS2 in ifcfg-eth0 or ifcfg-Auto_eth0 file. Instead, only the /etc/sysconfig/network file is used to specify the nameservers. 

Below is another example of setting up static ip on CentOS 6

## Configure eth0
# vi /etc/sysconfig/network-scripts/ifcfg-eth0

NAME="System eth0"

## Configure Default Gateway
# vi /etc/sysconfig/network


## Restart Network Interface

/etc/init.d/network restart

## Configure DNS Server
# vi /etc/resolv.conf

nameserver      # Replace with your nameserver ip
nameserver       # Replace with your nameserver ip

CentOS 6 - Change hostname

To check the host name of CentOS 6,

hostname -f

To change the host name on CentOS 6,
  1. sudo vi /etc/sysconfig/network
    1. Update HOSTNAME=[] to match the FQDN.
    2. For example,
  2. :wq
  3. If necessary, update /etc/hosts file for internal networking. Change the host that is associated with the IP address.
    1. sudo vi /etc/hosts
    2. change the host name as needed.
  4. Run the hostname command to change the hostname on the server. For example,
    1. sudo hostname
  5. Restart network 
    1. sudo /etc/init.d/network restart

CentOS 6 - Add a user to sudoers

Here are steps in adding a user to sudoers in CentOS 6

  1. Log on as root ( or switch to su with root password).
  2. On the command window, do the following.
  3. Enter "visudo". 
  4. vi loads the sudoer file.
  5. Look for %wheel in the sudoer file by entering " /%wheel "
  6. Remove # from the line "#  %wheel  ALL=(ALL)  ALL" to enable the wheel group with same privileges as root.
  7. Save and exit vi via  :wq.
  8. To create a new user:
    1. adduser   [new_user_name]
    2. passwd    [new_user_name]   [password]
  9. Use the usermod command to add the user to the wheel group:
    1. usermod   -aG   wheel   [user_name]
  10. Switch to the non-root user by entering "su  -  [user_name]"
  11. Test by running a command that's allowed for root only.
    For example, /root is generally accessible only by root user. Try listing the content of /root. 
    1. sudo  ls  -al  /root

Git could not pull because there were uncommitted changes

Recently, I could not pull from origin master on my Visual Studio 2017. Git could not pull because there were uncommitted changes. I forgot that every change in my local repo must first be committed before pull.

One easy way to commit uncommited changes and then pull was using command-line on the Visual Studio solution folder as follows.

git add -A
git commit -m "your message"
git fetch origin master
git pull origin master
git push origin master //To push to the git
