I'd like to interject for a moment...

These textbooks are trash and written by morons. When I was in college one of the required books said very clearly that sleep and hibernate are exactly the same thing. It said that both suspended to RAM and hibernate was just some lower power version of sleep. It was even a question on an exam that I got wrong for some reason. I argued with the professor about it and proved to him thats not the case by taking one of the lab computers, hibernating it, physically taking the ram out and swapping it with another computer and resuming into the same state on power on. He said “Well thats what it says in the textbook so I have to mark it wrong”

It really highlights that there are probably a lot of other inaccuracies that I didn’t notice. This is the standard of education nowadays.

Fun fact: G in GNU also stands for GNU.

Has anybody mentioned yet that tar isn't even a "compression format"?

If someone send this to Stallman, he'll write a stern email on emacs to the book's author reminding them that gnu is not linux.

Here's some more excerpts from the book that I found amusing:

As you learned in Chapter 1, Linux is an open source operating system, meaning that anyone can download and modify it. Open source operating systems can benefit from improvements contributed by thousands of programmers. Some people choose open source operating systems out of an anti-establishment spirit; others choose them as a practical matter because they are free.

"Anti-establishment" isn't the word I'd use, but I guess that fits.

One of the most popular distros for casual users, Ubuntu, comes with a DE called Unity (shown in Figure 5-16)

That hasn't been true since 2017.

Be suspicious of free apps. In the best-case scenario, the app does what it says but installs ads or other software. In the worst-case scenario, the free app is, or contains, malware that might steal personal information from your device, encrypt your data files and demand a ransom for decryption, or monitor your device usage. Installing an app sometimes asks for specific permissions that the app will use. Be selective in allowing app privileges to items such as contact lists, GPS location, e-mail messages, and so on.

Okay, I'll admit this is good advice if we're talking about "freeware", but there's also free/libre/open-source software, which has all of the benefits of freeware, and also gives you the freedom to read/mofify/share the source code, if you wish.

As for that "malware" you speak of, you might as well be describing Google Chrome.

No media player supports all formats, so it's important to find one that supports the formats of the clips you want to play.

Clearly, these people haven't heard of VLC.

Codec is short for "compressor-decompressor"

It actually stands for "coder/decoder".

And that's just one page...

Gentlemen, a short view back to the past. Thirty years ago, Niki Lauda told us ‘take a monkey, place him into the chair and he is able to use the computer.’ Thirty years later, Sebastian told us ‘I had to start my computer like an F1 car, it’s very complicated.’ And Nico Rosberg said that during the compile – I don’t remember what compile – he pressed the wrong button on the keyboard. Question for you both: is Linux today too complicated with twenty and more buttons on the keyboard , are you too much under effort, under pressure? What are your wishes for the future concerning the technical programme during the development? Less buttons, more? Or less and more communication with Torvalds?

GNU's Not... Linux

Missed opportunity to talk about tar being a tape format that we just happen to use on disks too (so it's accessed linearly, and in fact if you cat two tar files together they make a valid tar file.. or you can create a multi volume tar file that'll prompt you to change the tape).

CompTIA is a scam. No job that's worth a shit will require it.

GNU is Not Unix GNU is Not Unix GNU is Not Unix GNU is Not Unix GNU is Not Unix GNU is Not Unix GNU is Not Unix GNU is Not Unix

id like to interject for a moment. what your referring to as gnu, is actually linux/gnu, or as ive taken to calling it, linux + gnu

This whole table raises multiple questions. I guess I'll never hire someone mentioning comptia on their cv

In an alternate universe the sentence reads 'GNU is not UNIX' and leaves it at that.

I mean, it's technically correct? The G does stand for GNU, and GNU tools can be used to build Linux. It is indeed worded very badly.

I think you'll find that's GNU/Zip, or as I've taken to calling it GNU plus Zip.

So much to unpack here.

GNU is not a Linux variant. It is a set of programs and shared libraries.

ISO 9660 has nothing to do with compression. Just calling it ISO isn't a good idea for an intro class like that because it is a set of MANY standards. They should have put a little side blurb and called it ISO 9660 in the table.

tar is an archive tool. It has no compression.

Why no mention of compression algorithms algorithms vs archive tools?

Why not have different compression algorithms and their tradeoffs?

ETA: jar files are just zip files for Java libs/programs. You can open them with zip file tools.

This is great.

It's CompTIA. They're meh, at best.

High probability it is not fixed. This is the typical level of CompTIA quality I’ve encountered.

This sent me into full-body convulsions. How could you do this to me

Guhnooguhnooguhnooguhnooguhnooguhnooguhnooguhnoo

This is why I never bothered formally learning anything computer-related in school.

Sorry CompTIa is fucking garbage. In all my years at faangs, startups, Silicon Valley ycombinators, mid west tech, have I ever hired or worked with someone who has comptia certs.

Is it a good start to level 1 help desk at a hospital? Maybe. But I feel like it’s a fucking scheme where the time to learn any language instead would make you leagues better. Or study and get Cisco certs instead for neteng.

I’ll add it’s not that I chose not to hire CompTIa cert people. But I think in my 15 years I have never seen one come across the desk. The only time I saw it on a resume was level 1 help desk at a shop that thought Windows ME was the best release at the time and should be used in all rural hospitals and it was 2006 and anything beyond it was full of bloatware.

His company went bankrupt. Fuck you Arco

Well, GNU is a Linux based OS. Is they would write „GNU is a LINUX/GNU variant“ it would confuse more than it would teach.

@TheImpressiveX I’m still confused about GNU/ Linux thing.

When I had to learn Novell NetWare the textbook we received was just as bad and the instructor didn't have a clue either. Because internet wasn't exactly widely available for information like this then, we wrote a DOS batch file that discarded our input and miniced the output of the client for the practical exam. We all passed.
