A friend of mine is showing me how to use the shell (on my mac) and I used ls -a to look at all of the files in my home directory and there are a few that I'm wondering if they're garbage.
The ones that seem non-native to the computer (I'm running Mountain Lion)
.cups
.drjava
.nbprofiler
.netbeans
.profile
I googled netbeans (and "cups" unsuccessfully) and it seems like netbeans is an IDE, but I never installed it and it's not on my computer. I'm just curious if some of these files are garbage that piggybacked here on other downloads. Thanks for any knowledge you guys might have of this!

All of the files that you mentioned are part of Mac OS X already. Cups is to manage printers, netbeans is an IDE, drjava is for writing java applications, nbprofiler is to uncover memory leaks, and .profile can be used to set up aliases that act as shortcuts to commands. It is an optional file which tells the system which commands to run when the user whose profile file it is logs in. Hope this helped!

I'm a high school kid who's clueless about computing. I need to use PLINK on my MacBook for a bioinformatics project but I'm not sure how to even run it after downloading it. Any help would be greatly appreciated!
Firstly, you have to have jre or jdk installed. You can download jdk 8 (my preferred one) from the link. Just select the MacOS tab, and proceed.
Once downloaded, double-click to install.
Then, you have to download the application zip (here).
Extract it.
Double click on the gPLINK.jar in the extracted folder. If you faced an error, do the following: Open System Preferences> navigate to Security & Privacy icon > click on the lock icon below and enter password if required >on General tab, allow the program to be run.
Now the program must be launched successfully. You can move the .jar file to a desirable location, so that you will not forget where it was located.

this is such a beginners question but nevertheless wanted some of your input.
I tried installing SublimeText4 and noticed that there is no .dmg file associated with it, all i get .zip - is this normal? Usually with SBT3 and Pycharm I was used to at least some 'install' procedures.
Kind of new to Mac OS, so thanks for the help.
The DMG approach is common, but in this case, the ZIP file has the application. Often the browser will automatically unzip it for you, but if not, just double click on the ZIP file and the application will be extracted for you. Then you can just drag the app extracted from the ZIP file to your “Applications” folder and you are done.

How do I access an external hard drive through bash-on-Ubuntu-on-windows. It doesn't seem to appear in either /media, /mnt or /dev, which seem the common places that people say to look for them in Ubuntu systems.
Note: the hard drive is HFS+ formatted: I use Paragon's HFS+ for windows and have already done an apt-get install hfsprogs which I think should allow the Linux part to read the HFS+ format. I have also tried with normal USB sticks, no of which seemed to appear anywhere.
The drive does appear in /cygdrive in cygwin, but when I navigate to cygdrive in bash it doesn't appear. Clearly it is not properly mounted there, but is some form of symbolical link that bash cannot see.
I'm not really sure if this is a Linux or a Windows issue, but there doesn't seem to be anything from Microsoft about it, though I realise it is early days for them.
The Ubuntu on Windows on the current build (Build 14393, a.k.a. anniversary update) doesn't support accessing external drive. This feature is on their backlog for future consideration.

Edit: Mounting removable drives are supported since Build 16176. [1][2]

I am very new to programming in anything. I want to get started with Ruby. I have a pc and laptop. I don't want to limit myself to just the pc. As long as Ruby is installed on both, of course, can I keep my project files in DropBox so I can work on them from either device?
Thanks for your help.
Don
Yes. Source code files can be kept in Dropbox just like any other file. You can use Dropbox to keep your files in sync between your two computers.
As you find yourself more comfortable with programming and make programs of greater complexity, you will probably want to use a version control system (VCS), such as Git. Among many other things, a VCS will keep your project files centralized in a repository. If the repository is in the cloud (e.g. on GitHub) you will be able to access it from all your computers.

I am looking for a way to remotely install a program to other computer units running Windows on the fly ,without the need of running the installer steps on each computer (next,next,finish...) all over again , .exe installers don't usually have an easy way to do this without using the GUI installer.
a solution that i came up with , running the installer on a single pc
and try to trace each file the installer adds (location,file names,registry files) using FileSystemWatcher then copy these files and send them to the desired hosts that need the program installed with the location of each file will this work ? is there any easier implementation
the problem with FileSystemWatcher that although it detectes which files have been added,edited or deleted its not capable to tell which process did the change ,Why would i need to know ?,other programs depends alot on files and will keep editing them so i need to isolate the installer process to easily study how its functioning and what files are added..
the only way that i know to overcome this problem is developing a file system filter driver...
please give me your opinion or some recommendations on which is the best way to do this ,sorry for my bad english .
Almost every modern installer has some way to perform a silent install. You may need to do some digging to find the answers, or ask the publisher. Try running the installer with /? as a command line switch and see what it tells you.
