comment Must TCP use IP?
There is a lot wrong with this answer, and it misses the question entirely. First, Ethernet is just one link layer protocol that has been used to carry IP. There are plenty of others, and IP does not know or care about any of them. IP has nothing to do with the hardware; it is the routing layer between networks, above the hardware used to connect them. The point of the question was whether you can use TCP on something other than IP, not whether you can use something other than TCP that uses IP ( see UDP for an example of that ).

comment Understanding conversion and (de)compression of lossless audio
WAV always contains PCM. It might not be cd quality PCM ( but practically speaking, you generally can assume this because it almost always is the case ), but it will be PCM, not something else like mpeg 3 layer 2.

comment My pc shorted out and now it doesn't boot up
@izx, it's the plugging in of the second connector while the motherboard is already on that is the problem.

@MarioGarcia, plugging in power to a board that is already partially powered is also a good way to blow it up.

@Darius, no, it doesn't. Again, shorting out points on the bottom of the board and applying power is BAD.

@Darius, NO! Applying power while the motherboard has numerous points shorted out via foil is a surefire way to blow stuff up!

comment linux: accessing thousands of files in hash of directories
@130490868091234, readdir() returns the name, and inode number for each entry. Sort the array of entries, in order from lowest to highest inode number.

comment Is it perfectly safe to install grub bootloader on regular partition?
Note that when you install grub this way, it has to embed the sectors containing /boot/grub/core.img in the boot sector, and this configuration is prone to breakage, which is why grub complains loudly and makes you use the --force switch.

comment Improve performance of RAID SSDs (without TRIM) with periodic disk defrag? Lack of TRIM even important?
TRIM will always help the drive do a better job. Earlier drives had write performance fall off a cliff once you had written to every block on the drive at some point during its lifetime, leaving the drive with no free erase blocks. This is fixed with TRIM, but can also be significantly mitigated by the drive internally keeping a reserved pool of erase blocks that you can never write to, or by you making sure you never write to some parts of the disk by, for instance, leaving several mb of unpartitioned space.

comment Green flickering pixels that move with black images
I had a similar problem after getting a new PC at work. The monitor worked fine with the old one, but the new one had a DisplayPort output, so I had to get DP->DVI adapter. Tried two different adapters, and switching cables, and neither made the problem go away. Dell said it was the monitor, even though it worked fine with the old computer, so I just ended up getting a new monitor to fix the problem. Your explanation seems to fit what I saw. The new computer must have been slightly weaker and the new monitor is also weaker so the new pc can pull it down.

comment mdadm RAID Fast Setup with Empty Drives?
@Paul, the meaning of "empty" is not well defined. Most people use it to mean they have not put any files or a filesystem on the device, and do not know or care what it currently contains. If you know the disks are all full of zeros, then --assume-clean is what you want. It will take your word for it that the disks are all zeroed and not recompute the parity, and as you mention, a parity of zero will be correct for data disks of all zeros, at least for raid5 ( not for raid6 ).

comment mdadm RAID Fast Setup with Empty Drives?
@Paul, again, there is no such thing as "empty". Generally yes, it won't matter that the parity on stripes that have never been written is wrong, which is why you can get away with --assume-clean, even when the disks are not full of zeroes, but the wrong parity will be detected and corrected when mdadm does a parity check.
