Microsoft Excel becomes a powerhouse once you get into its expansive list of sorting options. Here we’ll cover its most straightforward option for sorting, a simple option that enables us to reorder data in specific columns.

If you don’t want to sort all of the data, you can also just select those cells you need by highlighting them, or by holding Ctrl and clicking to choose multiple unconnected cells. From the top of the page, click “Data” to switch tabs. Locate “Sort & Filter,” then click the “Filter” icon. This will add a small down arrow to the right of each heading. Click the arrow next to “Total $” and sort by largest to smallest or smallest to largest by clicking the appropriate option in the dropdown.

We’ve all been trained to archive every email we get. After all, we have basically infinite storage, and we can just find all the emails we need with a quick search, right? Makes sense. But that’s a trap. Gmail Promised Endless Storage but Hasn’t Kept up Whether or not you use Gmail, it’s important to understand that the idea of never deleting emails was widely popularized by Gmail. Before that, people generally deleted their emails regularly. You had to delete them to free up space so that you could get more emails. Gmail was earth-shattering when it was launched back in 2004. Google’s email service delivered a whopping 1 GB of free email storage. That put its competitors to shame—the free version of Microsoft Hotmail offered a tiny 2 MB at the time. Yes, Gmail launched with five hundred times as much free storage as Microsoft’s email service. It’s no wonder that Gmail became so popular. Its competitors struggled to keep up , but even they added much more storage space. … [Read more...] about Why You Should Delete Emails Instead of Archiving Them

End-to-end encryption (E2EE) ensures that your data is encrypted (kept secret) until it reaches an intended recipient. Whether you’re talking about end-to-end encrypted messaging, email, file storage, or anything else, this ensures that no one in the middle can see your private data. In other words: If a chat app offers end-to-end encryption, for example, only you and the person you’re chatting with will be able to read the contents of your messages. In this scenario, not even the company operating the chat app can see what you’re saying. Encryption Basics First, let’s start with the basics of encryption.

Some encryption systems have security flaws … [Read more...] about What Is End-to-End Encryption, and Why Does It Matter?
