15h	comment	Can you create a volumegroup in LVM that all the Logical volumes created under it will be thin provisioned? That's a nice answer to the question of how to create a volume group, and a thin provisioned lv within it, but that's not what the question asked.
18h	comment	Why my linux does not detect USB storages at runtime? Because you have a broken USB controller or driver.
1d	comment	How should I proceed with transfering sites from external hosting to in house? This is an overly broad question that amounts to "how do I do my job?". It's up to you to figure out what resources they require and provide them. If you aren't up to the task of really being a sysadmin ( and it sounds like you aren't and haven't had to in the past ), you should probably hire one and focus on your developer duties.
May 10	comment	What is user address space and what is it's purpose? You got that backwards; the data segment is for initialized variables, bss is for uninitialized variables. The segments are also defined at link time so can not grow.
May 8	comment	ldd tells me my app is “not a dynamic executable” This is wrong. Addresses changing does not matter at all. Functions being removed or other ABI breaks happen at major revisions of the library ( which are rare ), in which case, you would get an error loading libfoo2 if you don't have libfoo2 installed, whether or not you have libfoo3 installed.
May 8	comment	How to blacklist a correct bad RAM sector according to MemTest86+ error imdocation? By the time an error is detected ( if you even have ecc ram ), it is generally too late. Also free -m never reports an even power of two as the bios and kernel both reserve some ram.
May 7	comment	Ending Process Infinite Loop Input Redirection @Strawz, as their teacher it is your job to teach them that.
May 7	comment	Ending Process Infinite Loop Input Redirection @Strawz, if your student's program goes into an infinite loop on hitting eof, that would qualify as failing the test.
May 6	comment	Does rsync verify files copied between two local drives? There is no post-copy verification for any copies, local or remote. You run `rsync -c` again if you want to force it to check.
May 6	comment	`du` get different results on different machines for the same folder @misteryes, use `du -b` to get the apparent size rather than the actual used space.
May 6	comment	Cross-process dup on Linux The file descriptor is actually in kernel memory, and often is shared between processes, after being inherited from parent to child. And @pts, you can write to another process's memory with /proc/$pid/mem ( without ptrace ), you just can't write to invalid areas of it. You can even `mmap()` it so there's no copying going on.
May 4	comment	cleaning /dev/md0 filesystem ( raid) Check `dmesg` for error details.
Apr 30	comment	How to securely automate running commands as root with “sudo su -”? Scripts can't be suid.
Apr 29	comment	Why isn't Linux embraced as the official GNU kernel? @Nils, the Mach nonsense is another bit of popular misconception. NT has nothing in common with mach. Its "subsystem servers" are no different than unix daemons, which do not make a microkernel. Originally the gui was implemented in user mode, and this had only a passing resemblance to a microkernel system ( though so is Xwindows, that does not make Linux a microkernel ), but this was scrapped in NT4 and moved to the kernel.
Apr 29	comment	Why isn't Linux embraced as the official GNU kernel? @Nils, the question you linked contradicts your position, rather than supports it.
Apr 29	comment	Why isn't Linux embraced as the official GNU kernel? If you are going to claim that Linux is not POSIX conformant, you're going to have to back that up a bit. Including where the FSF says they require an absolutely 100% POSIX compliant kernel. By the way, Unix is not POSIX. Unix (trademarked) is a specific proprietary OS, so it goes without saying that no other OS can be that OS.
Apr 29	comment	Why isn't Linux embraced as the official GNU kernel? @vonbrand, whether you agree with it or not is irrelevant; it is the position of the FSF and because of that, Linux could never be a GNU project.
Apr 29	comment	Why isn't Linux embraced as the official GNU kernel? @MSalters, the FSF considers binary blobs to be non-free, and so since they are a part of the linux kernel, it is non-free, regardless of its license. You can write a program in a proprietary language that requires a proprietary compiler to build, and license it under the GPL, but if it requires non free tools to build, the FSF still considers it non-free.
Apr 29	comment	Why isn't Linux embraced as the official GNU kernel? @vonbrand, it doesn't matter what CPU they run on, they are part of the kernel sources, and part of the kernel binary. That's the definition of being part of the kernel.
Apr 28	comment	Why isn't Linux embraced as the official GNU kernel? Ahh, the proprietary drivers are another thing that GNU objects to. This was one of the reasons for GPLv3; to bar proprietary modules from being linked to free code, even at runtime, and why Linux chose to stay with GPLv2.
