An interesting video and I agree correct information is more useful than myths.

The guy has added Windows malware files to temp folders on his pc (probably by clicking spam or malicious links) and then he deletes them.

 

Amazing. ... lol

I wonder where he got that " Imagination " software he talks about from?  Sourceforge by any chance?   We know that they like to bundle stuff with legit software.  I bet it did not come from any official repo.

 

http://imagination.sourceforge.net/download.html

 

I still do not understand how his Linux system is infected with it.

 

Edit.

 

I wonder why he disabled comments on his video? Maybe so people cant comment or ask questions?

He points out that people are being mislead with inaccurate statements by members of the GNU/Linux community, and then (as a true community member) does the same thing. All I saw him prove was that GNU/Linux is complicated, the English language is complicated, and when you try to pair the two often things aren't stated as well as they could be, or explained in as much detail as they should be.

I'm not saying don't watch the video, absolutely do, it's an enjoyable watch. Nore am I trying to bash his video, he makes many good points, he's quite likable (I may have to checkout some of his other videos.), what he's attempting to do is a good thing, but take it with a grain of salt, as some of his statements are much like the ones he's debunking, misleading or incomplete.

 

.... After reading this back to myself, I had to think for a moment whether or not to post it. It seems to come off harsher than intended, but I can't think of a better way to word it so I'll just attach a few smilies to show it was written with a smile. :tophat: :) :P :) :tophat: :) :P

I wonder so myself, usually, many will respond to these videos. 

 

However, two of his points were correct, that about defrag, as I ran the same command as he did & here's the output. 

 

 

at@cat-XPS-8700 ~ $ sudo e4defrag -c /

[sudo] password for cat:

 Average size per extent 53 KB
 Fragmentation score 0
 [0-30 no problem: 31-55 a little bit fragmented: 56- needs defrag]
 This directory (/) does not need defragmentation.
 Done.
cat@cat-XPS-8700 ~ $ 
 

 

It's a 0, plus SSD's are not meant to be defragmented, so I'm not going to sweat it. That's what TRIM is for. 

 

And about reboot after updating, that's a given with any OS. And we've seen proof of it on this forum. 

 

One of his other statements though, I have an issue with. Over the course of the last 6 years, have installed Linux OS's to USB portable backup drives, for a portable Linux on HDD with lots of space. It boots w/out hesitation on every computer I've tried it on, be it Intel or AMD, same with Flash drives (though I don't prefer to run Linux on these). On newer computers, some BIOS changes needs to be made for this to happen, yet it's doable. Though I don't recall moving a HDD from one computer to the next, so can't vouch for that. However, doesn't that UUID come from the HDD itself? If so, why would it not be bootable? It doesn't change. And even if that were true, it's the same with Windows, Mac & Android. So in essence, this isn't a con or misrepresentation, I've never read any Linux manuals where it said this can be done. 

 

Finally, as to Malware, while most of us knows that Linux OS's can pick up a threat, it's rare that it affects our computers. Take a peek at the 'Am I Infected' section & see how many Linux users are in line. Sure, these can be spread to a Windows computer, that's why one should use the inbuilt tools (or the free Sophos for Linux) to scan the system regularly, and any files that are going to be transferred to another computer. 

 

While I feel that he may have covered some ground as it relates to the community, what he hasn't covered is the massive anti-Linux crowd that's stuck on Windows & that's what I was expecting of him. To address the real issues, rather than choosing a few random points from a 10 year old article. 

 

Honestly, I don't feel the Linux community is what's holding the brand down, it's those from outside that is & hopefully should he decide to do another video, do a discussion on those issues, of which there's tons of myths.

Performing full disc images weekly and keeping important data off of the 'C' drive as generated can be the best defence against Malware/Ransomware attacks, as well as a wide range of other issues.

Beginners at what? Creating YouTube videos! :hysterical:

 

He needs to stop rubbing his nose so much, if one were to do that on a job interview, would be seen as gross & having no manners.

You may have noticed he uses a SSD in the video.

Looks like TRIM is doing it's job very well.  :thumbup2:

You seen the video before we did? 

 

Well, if so, that means the ext4 journaling file system is doing it's job. Yes what he states is true & maybe that's why Linux stays fast, even on spinner drives. What he didn't mention was that Linux places it's files in positions to lessen the chance of fragmentation. 

 

 

 

  1. journaling file system is a file system that keeps track of changes not yet committed to the file system's main part by recording the intentions of such changes in a data structure known as a "journal", which is usually a circular log.

 

https://en.wikipedia.org/wiki/Journaling_file_system

 

To sum it up, the ext4 file system is a great file system that maintains itself.

These threads make some good point about his video as well:

http://www.linux.org/threads/matthew-moore-gets-a-virus-on-arch.8011/

https://www.reddit.com/r/linux/comments/33s60i/mythbusting_linux_guy_says_he_proofs_that_his/

 

Imho he has no idea what he is talking about. I didn't watch the entire thing, but the windows virus is obviously a joke. I tried downloading the imagination package from sourceforge and got no executables with it.. So he must've gone to some lengths to find the malware and even then could only find malware that would never run on his machine, making the claim completely meaningless.

the same is more or less true for the defrag, as has been pointed out above and is illustrated by the fact that none of us are actually in need of a defrage even though the machines have been running for years for some of us.

 

Regarding the reboot: This is partially true, but only for kernel upgrades which don't appear very often. From the new kernel 4 on kernel upgrades will be able to happen without a reboot, so that even less reboots are necessary. I get uptimes of 20-40 days on average. Not something that's happening on Windows if you patch regularly.

myrti
