What’s the difference between the Logitech M325 and the M325c
The Logitech M325 and M325c are both wireless USB mice. Their design appears to be identical (except for the various colourful variations of course), and their prices vary from anything between $12 and $60 – depending the layout and seller. Even the packaging is identical. So what’s the difference between these two models? Is it precision? Is it the build quality? Is it the year of production? Is it something else? Actually no, the two mice are absolutely identical and both work with Windows, macOS and Linux. The only difference...
read moreHow to check which web server is running on a domain
Sometimes we must know what web server is running on a particular domain. Usually web hosts should be able to tell a client this, but if the client is afraid to ask, there is a way to ask the web server directly for this information. Just to clarify: the web server is the process that serves files (HTML, PHP, ASP, images, etc) from a remote machine to your local web browser. The most likely choices in this day and age (2017) are Apache, NGINX or IIS. The latter is used by Windows servers, and the two former are used by Linux servers. There...

It’s not pretty when it happens, but it happens to the best of us: you forget the admin password for your Plesk Onyx installation. In previous versions there was an option to retrieve this password via the command line, but that special command has been removed in Onyx for security reasons. So what can we do? Well luckily it’s relatively easy to reset the password to something else, or gain temporary access to the server quickly. Let me show you how. Option 1: Login with server root credentials One option you always have is to not...
read moreHow to fix “connected to WiFi, but can’t see the Internet” on Windows 10
For the last few days I had a very interesting (read: ultra annoying) issue with Windows 10 on my Surface Pro. No matter which network I was connecting to, I could never see the internet anymore. Logic dictates that there was perhaps an issue with the router, but since it happened on other networks as well, this couldn’t have been the case. I could even ping the router, but no matter what else I tried, Windows didn’t see the internet. Finally I came across this Microsoft Support Article that suggested several things, among whose...

From time to time, the yum package manager may encounter issues with duplicate packages that are erroneously installed on a system. This manifests in a yum update going awry, telling us something along the lines of this: yum update ... --> Finished Dependency Resolution Error: Package: ntp-4.2.6p5-22.el7.centos.2.x86_64 (@updates) Requires: ntpdate = 4.2.6p5-22.el7.centos.2 Removing: ntpdate-4.2.6p5-22.el7.centos.2.x86_64 (@updates) ntpdate = 4.2.6p5-22.el7.centos.2 Updated By: ntpdate-4.2.6p5-25.el7.centos.x86_64 (base) ntpdate =...

read moreHow to print the current date and time in BASH shell scripts
Sometimes it’s useful to print the current time and date in a BASH script. We can make use of the date command for that. By default, and if called without any parameters, it’ll print something like this: echo $(date) Tue 29 Nov 2016 23:08:10 EST We can shorten this to just the date by using a formatting shortcut like this: echo $(date +"%x") 29/11/2016 or just the time using this format: echo $(date +"%r") 11:09:26 pm Formatting shortcuts can also be used together, like so: $(date +"%x %r") 29/11/2016...

BASH can deal with simple functions, and they are defined like this: # this defines the function function testing { echo "Hi there!" } # this calls our function testing As far as I know, BASH functions cannot take or return parameters.
read moreHow to use variables in a BASH shell script
Here’s how to use simple variables in BASH shell scripts. It appears there are no data types, and everything’s a string (correct me if I’m wrong). We can define a variable by first setting it to a value, then later refer to that value with a dollar sign in front of the variable name. Here’s an example: #!/bin/bash VARIABLE="Testing" echo $VARIABLE Note that there are no spaces between the variable name, the equal sign or the value. Adding those will result in a runtime error. Variables can be defined in upper...
