Override Windows Default Print Screen Button to Snip & Sketch

After taking screenshot, sometimes we need to crop the image on parts that we don’t want to show. There is more efficient way to do it. Windows 10 come with Snip & Sketch, a print screen tool.

We can override default Print Screen button behaviour to open Snip & Sketch automatically:

Snip & Sketch offer 4 different powerful print screen type:

  1. Rectangular snip. This is particularly useful for showing a part of window.
  2. Freeform snip. This can be useful for liquid shaped object.
  3. Window snip. Use this to take screenshot of a window. Snip & Sketch will automatically crop area outside of window.
  4. Fullscreen snip. Take full screen screenshot.

Print screen result is automatically pasted on Snip & Sketch. We can draw highlight mark if needed. We can also directly share the screenshot as email attachment.


DMARC is Domain-based Message Authentication, Reporting & Conformance. DMARC is an email authentication, policy, and reporting protocol. DMARC builds on the widely deployed SPF and DKIM protocols, adding linkage to the author (“From:”) domain name, published policies for recipient handling of authentication failures, and reporting from receivers to senders, to improve and monitor protection of the domain from fraudulent email.

DMARC is designed to fit into an organization’s existing inbound email authentication process. The way it works is to help email receivers determine if the purported message “aligns” with what the receiver knows about the sender. If not, DMARC includes guidance on how to handle the “non-aligned” messages.

At a high level, DMARC is designed to satisfy the following requirements:

  • Minimize false positives.
  • Provide robust authentication reporting.
  • Assert sender policy at receivers.
  • Reduce successful phishing delivery.
  • Work at Internet scale.
  • Minimize complexity.

How to deploy DMARC:

Email Default Address

It is possible to set a catch all email. Catch any email that is sent to an invalid email address for your domain.

While it seems a good idea to avoid potential customers mistyped our email and lead to sales loss, it’s a heaven for spammer. Because every random email abc@yourdomain.com, xyz@yourdomain.com are valid. Resulting you will receive all spams in your inbox.

So it is the best to leave to default option: discard the email while your server processes it by SMTP time with an error message.

Two Factor Authentication

Two-factor authentication (2FA) is an improved security measure that requires two forms of identification: your password and a generated security code. With 2FA enabled, an application on your smartphone supplies a code that you must enter with your password to log in.

Two-factor authentication requires a smartphone with a supported time-based one-time password (TOTP) app. We use Google Authenticator apps that available on Android, iOS, and Blackberry.

To configure two-factor authentication, perform the following steps:

  1. Login to cPanel.
  2. Click Two-Factor Authentication icon.
  3. Click setup Two-Factor Authentication.
  4. Install Google Authenticator apps on your smartphone.
  5. Scan the displayed QR code on cPanel with Google Authenticator.
  6. Enter the six-digit security code from Google Authenticator to cPanel Security Code text box.
  7. Click Configure Two Factor Authentication button.

HTTP will Become a Thing of The Past

The Internet want to make HTTP become a thing of the past in order to make internet a safer place to surf. Starting October 2017, Chrome version 62 will show “Not Secure” warning when user enter text in a form on a HTTP page.

Because Chrome has largest browser market share, website owner have no choice but to use HTTPS to settle in market. HTTPS also help in search engine ranking. Currently 30% of search result is HTTPS. Maybe a decade from now, all websites will be using HTTPS.
