Creating a Powershell profile is a great way to create variables or aliases that you can use in your day to day work.
The first thing you need to do is see if you already have a Powershell profile. You can do this by running the following Powershell command.
test-Path $Profile if you get the following result.
False
This means that you need to create a Powershell profile.
I was working with TypeScript today and I ran into a JavaScript problem that caused me some issues.
I needed to fix the number of decimal places in a temperature calculation example.
This is my original TypeScript code.
let printOutput = (fahrenheit: number, celsius: number) => { console.log(`${fahrenheit} f = ${celsius} c.`); }; let convert = (fahrenheit: number) => { let celsius = ((fahrenheit - 32) * (5 / 9)); return celsius; }; let fahrenheit = 100; let celsius = convert(fahrenheit); printOutput(fahrenheit, celsius); Returns.
I often use grep in Windows and Linux to find text in files. I have noticed that grep only works on traditional text files with .txt, .c, .cpp, .list, etc extensions. It doesn’t work with Markdown and C# text files and I find this frustrating.
I have found a parallel grep program in the Microsoft Learn code samples written by David Pine that overcomes the grep limitations.
The thing that I really like about this program is that I can use regular expressions in the search text.
I am used to gaining elevated privileges in Linux by adding sudo to a command e.g.
sudo apt-get update I wanted to stay in elevated privileges so I went to login as root and realised that my normal Linux account didn’t have root privileges.
I did some searching on the Internet and found that most versions of Linux disable the root account by default.
I found that you can enable root by running the following command.
I have been searching for a musical holy grail for a number of years (well what I would call a holy grail). Converting music files from one format to another is something I have been doing for years but I have always had trouble reformatting .iso files into high quality FLAC files.
I recently downloaded a Thelonious Monk album in .iso format and tried to load it into Foobar 2000, my music player of choice.
I have been using the Windows Subsystem for Linux (WSL) for a number of years and just assumed that I was using WSL 2.
A quick check told me that I was definitely using WSL 2.
Note: I am using Powershell to check the version of WSL I have installed.
wsl --status Returned.
Default Distribution: Ubuntu-20.04
Default Version: 2
Windows Subsystem for Linux was last updated on 3/11/2021
One of the shortcomings I find with Hyper-V is that it isn’t easy to copy files from Windows into my Hyper-V virtual environment.
I have found a quick and easy method to share a virtual Windows folder with Hyper-V and will describe how to set this up.
Starting a file share You need to open Control Panel and “Turn Windows Features On And Off”. From here select SMB 1.0/CIFS File Sharing Support and SMB Direct.
I have installed Hyper-V on my PC. I am going to use this to test various Linux distributions.
I have noticed that every time I load a new distribution as a virtual machine it doesn’t display full screen. I have to change the resolution to be able to see my Linux system in full screen mode.
One way to change your resolution is via the following:
Open a terminal window.
I am using the bash shell in Windows WSL Linux. Currently I am using the Ubuntu 20.04, Debian and OpenSuse distributions.
The problem I have is that the default colour scheme has an ugly green background colour with blue text
This is a really disconcerting colour scheme!
I looked around for an alternative colour scheme to use and found that I could run a command to change the colours manually but each time I opened the terminal I would have to run the command again.
I am having real problems keeping my ASUS netbook running. It doesn’t have enough specs to run a lightweight version of Linux.
Increasing the size of the swapfile is supposed to improve the performance of low specced machines.
I have worked out how to change the swapfile size in the hope that it may help.
To check if you actually have a swapfile.
swapon -s This will either return nothing or detail the swapfiles statistics.
