Tips for Scheduling Job Interviews

Are you trying to figure out when to schedule your job interviews? Here are a few things to consider that could help you make a good impression:

Avoid scheduling interviews on Fridays if possible. People are often busy wrapping up their work for the week, and they may not be as focused during the interview.
Consider scheduling interviews earlier in the week, such as on Monday or Tuesday. This is when people are more likely to be refreshed and focused, and you may have a better chance of standing out.
Alternatively, consider scheduling interviews midweek, such as on Wednesday or Thursday. By this time, the interviewer has settled into the workweek, but they're not yet distracted by the approaching weekend.

Remember, the goal of an interview is to showcase your skills and qualifications. So, select a time that works best for you and that will give you the best chance of making a good impression. Good luck!

Aside from just being more pleasing to the eye, shortened URLs can have the following added benefits:

More streamlined in appearance
If you’re trying to build a brand and are doing so through a social media campaign, having all your links be the same length and appear very similar is crucial.
Shortened links display better in emails, print material, and other places.
Tracking capabilities
Clicks on the link can be tracked
More validity in social media engagement:
A shortened link matching other links on your digital marketing materials and social media content lends validity to you as a business.
Long URLs with random characters and numbers can look shady, especially to someone who’s a new customer

OS Overview - Ubuntu Login Loop (Case & Solution)

Abdelrahman Aly — Sat, 06 Feb 2021 03:22:58 +0000

Motivation

OS is just Kernel and Shell which work hand in hand. The distribution (distro) is a combination of a customized shell(s) working on a kernel. This means, for example, Kali, Ubuntu, Fedora, Mint, etc are different distros that work on Linux kernel. The shell acts as an interface between the user and the kernel.

GNU (Gnu is Not Unix)

GNU is an Operative System. You can use this operative system with a different kernel such as Linux kernel, Hurd kernel, Darwin kernel, etc.

Windowing System

The windowing system is just the basic layer for a GUI environment. Every Linux distribution is a GNU operative system with a Linux kernel and a windowing system (X Window System is common on Unix like systems).

Window manager

A window manager is system software that controls the placement and appearance of windows within a windowing system in a graphical user interface. Most window managers are designed to help provide a desktop environment (An X window manager is a window manager that runs on top of the X Window System)

In the case of X or Wayland Window System, the shell consists of an X window manager or a Wayland compositor, respectively, as well as of one or multiple programs providing the functionality to start installed applications, to manage open windows and virtual desktops, and often to support a widget engine.

Linux Display Manager

GNOME Display Manager (GDM) is a display manager (a graphical login manager) for the X11 windowing system that lets you easily use your system. The X protocol has been at version 11 (hence "X11")

Ubuntu GDM uses the gdm3, which is the default GNOME 3.x desktop environment greeter in Ubuntu 17.

Wayland

Wayland is intended as a simpler replacement for X, easier to develop and maintain

Remote Desktop Control

Wayland sessions are not supported as incoming remote control connections such in AnyDesk and TeamViewer.

You could change it to Xorg on your login screen if you use Fedora

Login Loop

However, there are still a few pain points that simply couldn't be overcome for Ubuntu 20.04.2 LTS (Focal Fossa) (certain video card manufacturers stand out). Migrating everybody to Wayland in the 20.04 cycle would cause too many folks' systems to break.

If you face a login loop after changing Ubuntu with Wayland to Ubuntu, one of the solutions is to change the default display manager from gdm3 to lightdm through the following steps:

naser@cairo:~/$ sudo apt-get install lightdm -y

naser@cairo:~/$ sudo reboot

After rebooting you will notice the change in the interface

Click the white cirlce and chose Ubuntu (Default)

You will see the windowing system have been changed from Wayland to X11

Note: You may find that Screen lock disabled on the Ubuntu +20 flavors
