HOW TO: Make a Bootable USB by Downloading an .ISO or an Image Directly to Your Thumbdrive

Make a Bootable USB by Download an .ISO or an Image Directly to Your Thumbdrive

When you want to install a new OS, you usually create a bootable USB flash drive with the .iso of that OS. To do that you can use GUI programs like Etcher or Rufus or the dd command. Or maybe you’ll take the more convinient route and create a multiple-ISO bootable drive.

But, maybe, you just want to create an Ubuntu LTS bootable flash drive and just throw it in your backpack or hang it on your keychain, just in case you’ll ever need it. Maybe, for any reason, you don’t want to download the iso or image to your HDD/SSD. Maybe you’re out of space. But you really need to make a bootable drive.

You can just write the ISO files directly to your USB drive as you download it from the internet.

Man Page Alternatives

A few man page alternatives to help you be more productive

Man page. Short for manual page. It’s a form of software documentation usually found on a Unix or Unix-like operating system ( like Linux and macOS ). So when you’re using the terminal and you’re not sure how a command or a program works, you can always RTFM.

The problem with man pages is that, some pages, are massivly long and sometimes depending on the command or program it’s hard to find the information you need.

Here’s a few manpage alternatives that are abbreviated and straight to the point to help you be more productive.

The Easiest Way to Remove EXIF Metadata

the easiest way to remove metadata from files you upload online

 

When you upload a file online, you might upload more than what you’re willing to share with the world. This is valid for all types of file, being it a photo, a video or audio file, PDF etc.

The two most common file types shared online today are photos and videos. And both file types have one thing in common that can give away a lot more information than you might think. That’s metadata.

Besides what’s visible in the photo itself, metadata can reveal when and where the photo was taken, the device that was used to take the photo and other unique characteristics that can fingerprint you across the web. By not removing metadata, a hacker or OSINT researcher can easily find out where you live, where you work, your preferences and habits etc, just by extracting the Exif data hidden inside the photos you post online.

We previously covered why and how to remove metadata from a file before uploading it online, using an amazing tool called ExifTool.

If you find ExifTool too complicated to use or if it’s an overkill for your needs, here’s another free, open source and cross-platform GUI tool that’s built on top of ExifTool library: ExifCleaner.

ExifCleaner works with all file formats supported by ExifTool and allows you to process tens, hundreds, or even thousands of files at once by dragging and dropping those files onto the app window.

Also, the program automatically detects your operating system’s dark mode setting to reduce eye strain. It will change back to day mode when your computer does.

You can get ExifCleaner on Linux, macOS and Windows or build it from the source code. Linux users can download ExifCleaner as an .AppImage or .deb file.

HOW TO: Hide macOS Catalina Upgrade From Software Update

Simple way to hide an update in the software update preference pane

macOS Catalina was finally released to the public. And just like every other n00b fuccboi fanboy, I’ve immediately clicked that ‘upgrade now’ button. Long story short there were some glitches in the matrix and the upgrade went heywire.

What happened? Don’t know, don’t really care and I don’t have the time or patience to troubleshoot now. Apple should get their shit together with both iOS and macOS anyway.

But unlike a n00b, I had backups. So, my mac is now fully restored and it’s time to hide that macOS Catalina update in the Software Update reference pane.

If you also want to hide it, maybe you don’t want to update yet and don’t want to be tempted, or avoid somebody else that has access to your mac updating, here’s how you do it:

1. Open Terminal

2. Type sudo softwareupdate --ignore "macOS Catalina"

 

3. Poof. It’s gone…

 

4. To revert the process type: sudo softwareupdate --reset-ignored "macOS Catalina"

NOTE: you will still see ‘1 update’ next to System Preferences in the Apple Menu and if you have the System Preferences icon in the dock it will show the 1 update badge. Also…. this works with any other update that shows in the pane.
