Google’s New Gmail Features

Gmail’s biggest redesign is now live by

The world’s most popular email service is getting a big overhaul today. Google is making official the changes we saw leaked earlier this month, with email snoozing, nudging, and confidential mode making their debut alongside a substantial visual redesign for Gmail on the web. The new Gmail begins a global phased rollout today, which is to say that it won’t be available to every one of Gmail’s 1.4 billion users right away, and the first to get it will be invited to opt in rather than being able to just turn it on themselves.

Google recently announced a massive update to its popular email platform. So far, it's given personal account holders and company admins (who run company's G Suite accounts) the choice to leave their Gmail inboxes as-is, or to opt into the new Gmail, which comes with a new look and a lot of new features. If they don't enjoy the experience, users and admins are welcome to opt back out.

Understanding Mesh Networking


Mesh networks are an integral part of the burgeoning decentralization movement, and critical to realizing its vision. In this two-part article, we will provide a broad introduction to the concept of mesh networking: what are mesh networks and how did they evolve, why are they technically challenging, and what are the protocols that make meshing possible. Understanding mesh networking conceptually can help us make sense of the products on the market and to appreciate the operational constraints. Although mildly technical, the article will not assume any background in mesh or even general networking. 


mesh networks are an integral part of the burgeoning decentralization movement and critical to realizing its vision. In Part I we discussed the history of mesh networks and some challenges in making them work. The basic multi-hop mobile wireless mesh networking concept has been around since the 1970’s, under different names such as “packet radio networks,” “mobile ad hoc networks,” and “sensor networks” and has found applications in the military, first response, and recreation amongst others. Challenges specific to mesh networks include managing the link performance tradeoffs (e.g., throughput vs. range), decentralized access control and decentralized routing.

In a recent PCMag survey on passwords, only 24 percent of respondents reported using a password manager. The rest of you have a serious problem. It's almost certainly true that you are using passwords that are easy to remember, which makes them easy to crack. Furthermore, the plethora of sites you visit that require logins probably means that you recycle the same passwords over and over, too. Maybe you think that securing your online accounts is unimportant, or too much trouble. Trust us, that's not the case. Using bad passwords can have serious consequences.

Google Advanced Protection Program: Everything you need to know by

Google takes account security very seriously. You may be giving up more of your privacy than you like by using Google services and hardware, but that's not the same thing as account security — and Google takes some pretty big steps to keep unauthorized users out of your account. The company also has some tools and policies designed to keep youfrom letting an unauthorized user in, like Chrome blocking websites that host malicious content. Google depends on you trusting them with your personal data as its business model. Playing fast and loose with security is a great way to lose that trust and Google knows it.

Spectacular time-lapse footage from the European Southern Observatory's Very Large Telescope (VLT) in Chile captures stars orbiting the black hole at the center of the Milky Way, including one daring star that circles incredibly close.

A monster black hole called Sagittarius A lies at the heart of the Milky Way, about 26,000 light-years away from Earth. The footage, taken during a 26-year-long observation campaign, revealed that a small group of stars orbit this gravitational monster at high speed.

A Unique Username Can Add an Extra Security Layer

A Unique Username Can Add an Extra Security Layer

Create a random and unique username and password for each web service.  Use a "Password Manager" like LastPass to remember and store them securely.

Many people use the same online username across multiple platforms and websites, from Gmail accounts to banking websites. One exposure to a person’s username can open the door to identity theft.

Back in 2014 Snapchat has a data breach it affected 4.6 million usernames and mobile numbers, more recently Yahoo lost control of databases containing information of over a billion users. Even compromised government sites have leaked user data. Using a randomized username is like having two passwords for an account because it makes it harder for someone to guess your username and break in. These cybersecurity hacks are happening more frequently targeting both usernames, and email addresses.

For almost anything you do online you need a username. Rather than using the same email address to log into Twitter, Instagram, Facebook, Amazon, and other online sites, you can create a unique online name. 

Unique usernames can be useful in a few different ways. 

  • Using different usernames for some of your accounts makes it harder for hackers
  • If your username is something unique or funny, it is easy to remember
  • It makes your profile memorable on Facebook, blogs, and forums

Username tips from the pros

  1. Email usernames and bank account usernames should be different.
  2. Never use your SSN or financial institution account as a username.
  3. Decide if your username protects your identity or can be public.
  4. Create a username that is simple enough to remember but hard to guess – and store it in your password manager.
  5. Avoid using familiar numbers with your usernames, such as an address or birth dates. 

There are various ways that you can create usernames. You could sit down and brainstorm some fun things yourself. Another approach is to get a little help, try a free online username generator. 

Here are a few username generators to try.

After creating a custom username using one of the above tools save it safely in LastPass.

Things to Consider When Choosing Usernames

You could make a unique username for each website or do them in groups. For example, you could use one username for your professional interests and another for your email, services, and sites. Doing this creates some separation and makes it harder for people to track you online.

If using a username professionally, remember it can be the first impression a business associate or potential client will have of you.

Try to stay anonymous. In most cases, try to keep identifying info out of your username. JohnSmithOakDrive would give away to much information about the user.

Check out the rules for each site. Some sites have a limit for how long your username is.

Protect your Username with a Secure Password and store them in a password manager like LastPass.

When choosing a username, you should also give some thought to online security. You need to protect your usernames and passwords. If your username and password are stolen or hacked in a security breach, cybercriminals and others could access your financial accounts, use your info for identity theft, or hurt your reputation online.
