Moving to a new operating system (whether it’s Windows, OS-X or a Linux OS that’s new to you) it’s often difficult to find what you are looking for — at first, and they all have some kind of a fancy way of displaying system information.
These graphical methods present a nice browsable list of information, but with a terminal command line, however, you can really dig under the hood of your Linux computer’s hardware.
Many youtube channels incorporate their own thumbnail onto the video. Many does it only for the purpose of clickbait, while most does it to represent the content of that video. No matter the reason, it’s sometimes useful to download that thumbnail. Let’s use a physics video by ilectureonline.com to see how we can get that static thumbnail.
GDC hosted a while ago two pretty interesting talks on the development behind Doom and Diablo (the latter in 20th anniversary).
Doom: A Classic Game Post-Mortem (by John Romero & Tom Hall)
Diablo: A Classic Game Postmortem (by David Brevik, Lead Programmer)
The Deployment Image Servicing and Management tool (DISM) is perfect for IT professionals and power users that want to manage Windows components without using the GUI.
Linux is one of the most astoundingly functional and utilitarian Operating Systems around when it comes to working from the command line. Need to perform a particular task? Odds are there is an application or script you can use to get it done in the terminal. But, once in a while we all need some changes in our lives, preferably something colourful. So here is a collection of strange, funny, or even downright pointless things you can do right in your Linux terminal.
Many of the beliefs we have around what constitutes a “good” password are created by what default policies in software, such as Microsoft, teach us. We are led to believe that a minimum length of 8 characters, a good mixture of UPPER and lower-case, numbers characters automatically make a good password. So what constitutes a strong, but also an easy password to remember? Are they in conflict with each other? Not necessarily.
Let’s delve a little into the analysis behind today’s passwords.
In Linux/UNIX, the concept of a user (owner) and group is very fundamental, as everybody want things to be kept secure and properly organized. The system was designed with security and ownership in mind, and this is why every file and directory has an owner and a group associated with it, and they have different permissions to access that particular file. So, how can we manipulate permissions with chmod, umask, chown and chgrp?
If you’re a Linux user, you’ve probably seen references to both sudo and su. These two commands are different ways of gaining root privileges. Each functions in a different way, and different Linux distributions use different configurations by default.
Starting a program, file management, system monitoring and more can all be performed without a single mouse click. Some swear by the command line, while others are happy never to have to encounter that intimidating black screen. If you’re the curious type and want to explore the full power of your Linux system that your GUI conveniently hides, then read on.
