Using Cygwin in Windows 8, chmod 600 does not work as expected?
I'm trying to change the permissions to my key file in Cygwin 1.7.11. It has the permissions flags: Reports: mode of 'key.pem' changed from 0660 (rw-rw----) to 0600 (rw-------) However: still reports key.pem's permission flags are still: -rw-rw---- This reason why I'm asking is that ssh is complaining: Permissions 0660 for 'key.pem' are too open. when I try to ssh into my Amazon EC2 instance. Is this an issue with Cygwin & Windows 8 NTFS or am I missing something?

How to access an SD card from a virtual machine?
I want to format an SD card from my Linux virtual machine. I have a built-in SD card reader in my laptop. I tried using VirtualBox and VMware Player and installed Ubuntu 10.04 guest. None of them are showing the SD card reader as a device. I can access the SD card from the Windows host. I am not interested in solutions using shared folders as I want to access the SD card as hardware (it should show up in ). I basically want to set up the SD card for BeagleBoard, but I don't want to install a physical Ubuntu on my PC.
I washed my USB drive. Any long-term risks?
I accidentally left a USB flash drive in my clothes, which was then washed with my laundry. This was a colored load, hot water. The drive survived just fine and was very clean. All data was still there, and I see no physical damage. Am I risking any long-term data loss/drive damage due to this washing affair, or is there no additional risk now that I see the drive has not suffered any initial damage?

Using UDF on a USB flash drive
After failing to copy a file bigger than 4G to my 8G USB flash drive, I formatted it as ext3. While this is working fine for me so far, it will cause problems if I want to use it to copy files to someone which does not use Linux. I am thinking of formatting it as UDF instead, which I hope would allow it to be read (and possibly even written) on the three most popular operating systems (Windows, MacOS, and Linux), without having to install any extra drivers. However, from what I found on the web already, there seem to be several small gotchas related to which parameters are used to create the filesystem, which can reduce the compability (but most of the pages I found are about optical media, not USB flash drives). I would like to know: Which utility should I use to create the filesystem? (So far I have found and , and seems the best option.) Which parameters should I use with the chosen utility for maximum compability? How compatible with the most common versions of these three operati…

What medium should be used for long term, high volume, data storage (archival)?
This question was inspired by https://superuser.com/questions/374386/how-to-store-and-preserve-lots-of-data. There have been other similar questions, but none with the same criteria. This is two questions in one. How do you store financial/critical records that should survive anything but a fire and should be available for decades? Lets say I want to store family photos/videos and want people do be able to find them in storage 100 years from now and still be able to use them. How would this be done? Criteria Long term means 30+ years guaranteed. 100+ years average. [If this is not practical, use the closest solution] High volume means a couple terabytes. Answers can be 'no-compromise/industrial' solutions or practical solutions for the home office/small business user. Media will not be active during the timespan. (i.e., if you suggest hard drives, they will not be spinning). Further, there is no expectation of needing to read these archives. They are there for emergency or "for future…
Continuously re-execute a command when it finishes in Bash
I'm trying to figure out a simple way to keep re-executing a command whenever it finishes, for any reason (error or otherwise). What would be the best way to approach this? EDIT: I wasn't clear enough before. I need the next execution to wait until the previous one finishes. EDIT 2: Almost all answers work great. I mistakenly thought most answers would either fork the process or re-execute it just once, neither of which is wanted.
