Understanding Linux/Unix/Arch - not the same thing as using it

Hi there Archers!
I've been using Linux for almost a year now. I started out pretty rough, with Fedora - and uninstalled it pretty quickly as it wasn't the easiest OS to start with, and I didn't have that extra time to learn it by then. I then proceeded with Ubuntu and Mint, until I decided at the beginning of May 2013 to become an Archer/Archie. I'm proud of this decision. (y)
Using Linux and understanding it as I have learned are two entirely different thing, oh so different. I hope this isn't too much to ask for, but I would very much like the advice of some experienced users - which I presume I will find here, easily:
I want to understand Unix/Linux better, maybe not the whole Arch concept - since The Arch Way isn't that hard to understand, at least not the concept. What shall I read and do? I know there is much information out there - but I have no desire to read things that you guys don't find helpful, and I am looking for some pro-tips.
Thanks.

Which aspect of Unix / Linux do you want to understand better?
Options include:
Networking
Servers
System administration (user accounts, permissions)
Software development
Package management
Differences between distributions / operating systems
Kernel compiling
The Linux Standard Base (LSB)
Shared libraries
Version control software
Embedded linux
The init process, boot manager, and dual booting
File systems
And other stuff.
I was thinking a basic mix of everthing above, basically. Like: What are libraries? How does the system administration work? How does the kernel work? Etc. I mean - the answers are often not so complicated to understand on a basic level. My problem is, I don't know what questions to ask.
I think I'm looking for some "tasks" which don't require a lot of time, I don't really HAVE the need to do extremely much on my Arch - but I would love to be ABLE to do more.

Yes, you are right - that is what I meant.
General response: Thanks to all of you so far. I'm starting to understand what I should do, just hoping I'm on the right track now.

I don't remember my iCloud username that was used when I set up my Iphone4s. I know my apple ID but that is not the same thing. I need it to activate my phone.

Write a SELECT statement in different ways is not the same thing!!!

Let's take a look
use AdventureWorks2012
go
dbcc freeproccache
go
and now select something
select * from [HumanResources].[vEmployeeDepartmentHistory]
go
so, analyzing 'Compiled Plan'
SELECT usecounts, cacheobjtype, objtype, text
FROM Sys.dm_exec_cached_plans
CROSS APPLY sys.dm_exec_sql_text(plan_handle)
where cacheobjtype = 'Compiled Plan'
ORDER BY usecounts DESC;
GO
and now let's write some SELECT in "fuzzy case"
dbcc freeproccache
go
select * from [HUMANResources].[vEmployeeDepartmentHistory]
go
select * from [HumanRESOURCES].[vEmployeeDepartmentHistory]
go
select * from [HumanResources].[VEmployeeDepartmentHistory]
go
select * from [HumanResources].[vEmployeeDEPARTMENTHistory]
go
select * from [HumanResources].[vEmployeeDepartmentHISTORY]
go
SELECT * from [HumanResources].[vEmployeeDepartmentHistory]
go
select * FROM [HumanResources].[vEmployeeDepartmentHistory]
go
and now let's see compiled plans again
SELECT usecounts, cacheobjtype, objtype, text
FROM Sys.dm_exec_cached_plans
CROSS APPLY sys.dm_exec_sql_text(plan_handle)
where cacheobjtype = 'Compiled Plan'
ORDER BY usecounts DESC;
GO
So, write a SELECT statement in different ways is not the same thing!!!
Hope it'll be useful

Yes. There is little or no query normalization that happens in front of the query plan cache. It would be a performance tradeoff to parse and normalize the query before matching it to the cached plans. The benefit of reducing the number
of plans in the cache probably wouldn't be worth it.

Mini DVI and Mini DisplayPort are not the same thing!

I bought this "Mini DVI to DVI" adapter thinking it would hook up my Epson projector to the new MacBook Pro:
http://store.apple.com/us/product/M9321G/B?fnode=MTY1NDA3Ng&mco=MjE0NTE2OA
BUT tonight I found out it is NOT the right thing. The adapter I need would be "Mini DisplayPort to DVI (or VGA)"
I found the full sized DVI ♂ and ♀ ends of the adapter and projector cord I do have don't "mate" right either. The pins have a slightly different arrangement!
I just want to warn anyone who might stumble in the same place. I'm off to my local Apple Store to return the adapter for one that will fit one of my projector inputs with a Mini DisplayPort plug on the other end.

Good call!! Thanks a million. Glad I asked & thanks for the quick response. I was getting frustrated. Thanks again!!!!!

Finder Folder defaults, not the same defaults when using Office Mac2011

I might be being a touch simple here - i've got my file formats sorted nicely in Finder (excuse my simple terms here, new to iMac, love it though..) and the default view opens each time without issue.
What I want now is the same default view when I open, save, save as etc anything out of Office Mac2011. Currently files, documents and folders are all over the shop. I can't find anything obvious like there is in Finder to re-sort the default views etc.
Anyone help at all...?
Ta!

Not possible. The open and save dialog boxes don't reflect what you've set as view options for Finder windows.

Java vs Javascript NOT THE SAME THING

Since we're all just users here it might be appropriate to remind people that Java and Javascript are two distinctly different things. With the recent warnings about Java some might be inclined to also disable Javascript in their browsers. There is no need to do that.
Even thought the two frameworks have similar names they are not related.

Ask your question.Are synching and backing up the same thing?

My phone automatically synched when I plugged it in to my computer. I was told to back it up before I did an update. Is synching the same as backing up?

First thing done every time you sync is an iPhone backup, and no they are not the same things.

Is there a plugin that will do the same thing as Zemanta?

I have the Zemanta plugin and, for the most part, it works well. However, it does make some glaring mistakes. For example, when I'm done writing my blog, and before I publish it, I'll hover over one of the In-text Links at the bottom of the editor (a Blogspot blog), the word "sauce" for example. The recommendation is "Ranch dressing". While sauce and Ranch dressing are both liquid, they're really not the same thing. If I do the same with Italian dressing, Ranch dressing will be suggested. I've mentioned this to the Zemanta folks, and the "best" answer I could get was that someone is promoting Ranch dressing.
Is there another Firefox add-on, that works with Blogspot (Blogger), that will do the same as Zemanta?

Try doing a search for an addon like that. <br />

Is FC analyser and Fabric analyser the same thing?

Folks,
Is FC analyser and fabric analyser in MDS series switches the same thing. I am confussed. Also,
Does the FC analyser has a Test based ( Etherreal) and GUI based interface? has anyone installed the GUI interface? which one is better?

The Cisco "Fabric Analyzer" that is included with the MDS is a tool for monitoring control traffic on the switch - in other words, anything that passes through the Supervisor module. It has both interfaces, or you can export the traffic to a file and look at it later with another GUI (ethereal) if you like.
You can also use a SPAN port to monitor all traffic on a specific port. Perhaps this is what you are referring to as "FC Analyzer". Typically you would use a PAA to capture the traffic using ethereal or maybe a hardware protocol analyzer. ($$$!)
So, to answer your question - No, they are not the same thing (if my assumption about your description is correct).

I've reset my PPAM before to get around Firmware lock, but I've upgraded to mountain lion and now need to do the same thing, but I can't reset the PRAM. I've heard of the chip that is on the post 2011 macs, but I must not have one? What to do?

I've heard of the chip that is on the post 2011 macs, but I must not have one? What to do? Also, I can not get start up chimes unless I have the factory startup disk in. Can the PRAM be reset with the factory startup disk in or must the mac boot from the hard drive? Need help.

I am getting a pop up on my iPhone 4S asking password of my iCloud even though I feed the password but still keep on asking the same thing every second so I am not able to use my iPhone.

I am getting a pop up on my iPhone 4S asking password of my iCloud even though I feed the password but still keep on asking the same thing every second so I am not able to use my iPhone.at various times it asks different passwords.

Curretly, there is an iCloud blackout. It started this morning around 2AM California time (Pacific), 5AM New York (Eastern). A lot of people have been having issues all day, including me. No iCloud services are online. Even Find My iPhone is down.

HT201210 could not back up iphone to this computer. I have bought a new phone iphone 4 and it says the same thing. though I have another iphone 3 that backs up perfectly to this computer every time. why?

I had 2 iPhone 3G's, one of them screwed up and wouldn't recieve service. Up until then when I backed them up to my computer all was good, then one of them would update and all but a screen would pop up and tell me it couldn't back up to my computer. Recently I replaced the bad tele with an iPhone 4 and it does the same thing while the other iPhone 3G still backs up fine.......What up!!! Help please. Don't wanna lose my info..

I banged my head on the wall with the same problem for two days. Tried everything mentioned, and this worked, finally. The problem is that the backup files are not where you think they are.
You need to delete the MobilSync backup folder. I have a Mac. Went to /Library/Application Support/MobileSync/Backup and deleted the Backup folder.
Fixed the problem. Give it a try and good luck!

My Iphone will not let me download apps because it says my apple id is disabled, I have changed my password four times and it still is saying the same thing. What do I do now?
