The answer depends on what you’re looking for: Linux is all about choice. What’s the Difference? To pick properly, you’ll need to understand the strengths of each “flavor.” That might be the bling and polish of Kubuntu, the “set it up and forget about it” of Ubuntu, the retro simplicity and stability of Xubuntu, or the ability of Lubuntu to run on older and less powerful hardware. Despite the different names, all of these are based on the same underlying Ubuntu software. They include the same Linux kernel and low-level system utilities. However, each has different desktop and flavor-specific applications. That means that some are more full-featured, while others are more lightweight—so each feels a little different.

DB Browser for SQLite lets you view and edit SQLite databases on Linux. You can design, create, and edit these database files, and peek inside the inner workings of other applications.

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. In your spreadsheet, highlight the row with the headings you want to sort. 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. This option works for any number, so we can also use it for the “Sales” and “Product ID” sections. Words, on the other hand, are sorted differently. We can sort these … [Read more...] about How to Make Sortable Headings in Excel
