Simplified way how I understand Blockchain

 There are many technical definitions of Blockchain. This is how I, as an accountant, understand it. This will be the new process for some  transactions. DPWH will launch Blockchain technology. DBM is using Blockchain. 

Blockchain is like a public digital notebook that 

1. everyone can see and authorized people to verify, 

2. but no one can erase or change once something is written.

1. (everyone can see and verify, ) All people can download the verified list.  

Verifiers must input the correct information; incorrect input will lead to erroneous data within the Blockchain. They can make another file  to disclose the wrong original data. 

2. (no one can erase or change all public data  once something is written.)

It will not be realistic  for person no.1 to ask all people who downloaded the file to change the verified list. The verified file is link to a blockchain technology to maintain the security of the verified files.

Picture below shows 

1.  Sample file generated by a sample  app. It has Blockchain hash, token no. ,  date , time stamp and raw time stamp that is unique for all tasks. 

2.  Actual DBM Blockchain file. 2nd file  to show the error of original file. Original file no one can edit.

How to give your old laptop and desktop the second life?

 

Chrome OS Flex: An Overview

What is it?

Chrome OS Flex is a free, lightweight operating system from Google that is designed to give new life to older computers that previously ran Windows or Mac OS. It is a cloud-first OS that uses the Chrome web browser as its primary interface.

Pros:

• No Windows issues: You can avoid common problems associated with Windows, such as frequent updates.

• Simple and fast: The OS is designed to be lightweight and efficient, making older computers feel new again.

Cons:

• Browser-based tasks only: All tasks are done within the Chrome browser.

• Data loss during installation: The installation process will erase all data on the USB drive and the computer's hard drive.

"Out of the Box" Application Ideas:

Secondary Media Device: One idea is to use an old laptop or desktop "as your you tube player." This minimizes the load on a main computer ("Minimize the use of your main laptop").

Focus Enhancement: Another application is to "Separate the chrome based function from your main laptop to increase focus on task." By dedicating a machine to browser-only tasks, users can reduce distractions on their primary work device.

Preventing Hardware Idleness: The OS is positioned as a solution for "Still using an old machine to prevent it to be idle for a long time." This is particularly relevant as "windows and other operating system has more hardware requirements to use it properly," implying Chrome OS Flex has lower hardware demands, making it suitable for less capable machines.
