Stop using pie charts in Excel: build this dynamic bar chart instead

You’ve finalized your Excel spreadsheet and want to visualize your numbers. A pie chart is a tempting option: it takes 20 seconds to create and makes you look sophisticated. However, it often causes more confusion than it solves. To truly impress your coworkers and make your data pop, ditch the circle and build a bar chart that updates itself.

Once you move past three or four slices, pie charts become unreadable, often requiring messy legends and manual labels that clutter the screen. More importantly, even if you sort the underlying data feeding a pie chart, the circular format makes the hierarchy difficult to follow—leaving your visuals in a jumbled mess. By taking the hallmarks of a pie chart and applying them to a dynamic bar chart, you solve all these problems—no legends, no clunky labels, and no confusing order.

Cum activezi Memory Ballooning pentru mașini virtuale în Proxmox VE

Într-un mediu virtualizat Proxmox VE, este posibil ca mai multe mașini virtuale să rezerve memorie RAM pe care nu o folosesc în mod constant.

Acest lucru poate duce la:

  • utilizare ineficientă a memoriei serverului

  • imposibilitatea pornirii unor VM-uri noi

  • performanță scăzută când resursele sunt limitate

Proxmox oferă o funcționalitate numită Memory Ballooning, care permite redistribuirea dinamică a memoriei între mașinile virtuale în funcție de necesități.

6 commands to clean up your Ubuntu system from the terminal

Keeping your computer free of digital clutter is an important part of maintenance, while also making sure you always have space for new files and programs. Here are some simple commands that will let you clean up your Ubuntu system from the terminal, no GUI required—well, with one exception.

Note that in most cases, these commands will work on any Debian-based system. I tested them on both an Ubuntu install, as well as a Linux Mint machine. On both systems, I gained a lot of space, a lot more than I expected, in fact.

Why Excel conditional formatting breaks

It’s a familiar situation for every Excel user: you open the Conditional Formatting Rules Manager and discover that the neat little rule you created has somehow multiplied into dozens—or even hundreds—of fragmented copies. The formatting that once worked now behaves unpredictably.

Behind the scenes, Excel splits and duplicates rules to preserve formatting logic. However, each redundant rule clutters the UI and can slow your workbook down.
