• How to Format a USB drive in Debian

  Formatting a USB is a common operation in most computer systems and it comes in handy in a number of ways. For instance, you can format a USB drive if it gets infected with a virus, and data is corrupted or you want to change the file system as it is not compatible with your OS. Similarly, it can be helpful if you want to completely wipe off the old data so that you can fully use the storage space. So whatever the reason, you can easily format your USB device through different methods in a Debian operating system. In this article, I will show you different methods to format a USB drive on the command-line and on Debian Desktop. You can use either of them based on your preferences. Note that we have run the commands and procedure mentioned in this article on a Debian 10 system.

• Linux Netstat Command Tutorial for SysAdmins [40 Examples]

  The netstat (network statistics) utility in Linux provides information related to network connections. You can use various netstat commands to display active network connections, interface data, routing tables, and so on. These are essential information for network admins and infosec professionals. That’s why we have prepared this guide with a wide selection of useful netstat examples. After completing this guide, you will be able to inspect all the network-related information for your Linux machine. We also encourage readers to try these examples on their own machine for obtaining a more hands-on experience.

• Linux Fu: Troubleshooting Incron | Hackaday

  You probably know about cron, a program that lets you schedule programs to run at various times. We’ve also talked about incron, which is very similar but instead of time, it reacts to changes in the file system. If you ever wanted to write a program that, say, detects a change in a file and automatically uploads it to a programmer, backs it up, e-mails it somewhere, or anything else, then incron might be for you. Although we’ve talked about it before, incron has some peculiarities that make it very difficult to debug problems, so I thought I’d share some of the tricks I use when working with incron. I was thinking about this because I wanted to set up a simple system where I have a single document directory under git control. Changing a markdown file in that folder would generate Word document and PDF equivalents. Conversely, changing a Word document would produce a markdown version. This is easy to do with pandoc — it speaks many different formats. The trick is running it only on changed files and as soon as they change. The task isn’t that hard, but it does take a bit to debug since it’s a bit nontrivial.

PolarFire SoC board has GbE port and 40-pin GPIO

Sundance will soon launch an SBC-like, $995 “PolarBerry” module that runs Linux on Microchip’s FPGA-enabled, RISC-V based PolarFire SoC with 4GB DDR4 and eMMC, dual CAN, a GbE port, and RPi style 40-pin GPIO. Microchip’s PolarFire SoC, the world’s first SoC to combine a Linux-ready RISC-V architecture CPU with an FPGA, has so far appeared on an Aries M100PFS module and Microchip’s own PolarFire SoC Icicle Kit SBC. Now, UK-based FPGA manufacturer Sundance has announced a Raspberry Pi sized PolarBerry SoM equipped with the hybrid SoC. It will soon launch on Crowd Supply for $995, with shipments due in January.

Enable a Magic Lamp Effect on Ubuntu with this GNOME Extension

Called “Compiz-alike magic lamp effect”, this a free, open source GNOME Shell extension does an excellent job of recreating this famously flashy window minimisation effect on the Ubuntu desktop (as well as other Linux distros which use GNOME Shell). The “genie effect” animation is synonymous with Mac computers as it was the default window minimisation effect used during the early years of the system. Notably, the effect was first shown off during an Apple keynote way back in 2000 — it’s been around that long! Linux users wanting to add the animation to their systems have had several ways to do it over the years. The best known effect is the ‘Magic Lamp’ effect for Compiz, the 3D composited window manager, though (naturally) elementary OS provides it too.
