comment What happens if 2 devices want the same static IP address?
@Vinayak, not so. The NIC doesn't know about IP; it is the OS that "claims" the IP address by choosing to respond to ARP requests from other computers ( they are broadcast ) asking "who has this IP address?"

Don't. HTML does not belong in email.

comment Is a high Collision Count in WAN an issue?
Assuming this is a cablemodem, then it is not unusual as cable is a shared medium. You and many of your neighbors are using the same copper wire to transmit, so at any given time, only one can do so. Sometimes two try, and you get a collision.

comment Why use codes for login names
Because they are idiots. We came up with a very simple and effective way to stop guessing passwords in the 1960's: after you try and fail a few times, you don't get to try any more. See also: xkcd.com/936

comment difference between gparted align to MiB and Cylinder in micro SD Card
There is absolutely no reason it should make a difference, so I'd say try again. Cylinders have been a vestigial fiction in hard disks for 20+ years now, and never had any meaning with flash sd cards.

comment Networking fundamentals: Does a Gbps LAN has a better latency than a 100Mbps LAN?
@Gizmo, that didn't make sense. If the bottleneck is the HDD, then a faster network isn't going to help.

comment What is the diference between IP subnet mask 255.255.254 .0 … or 255.255.255.0?
Just to add a little clarity, if you have two computers on your network with addresses 192.168.0.1 and 192.168.1.1 and a netmask of 255.255.255.0, they could not communicate with each other ( unless you set up a router ) because they are on two different logical networks, even though they share the same physical network.

comment PCIe card and x8/x16 lanes
Yes, and the "non modern motherboards" just disable the on board graphics regardless of whether the card is a GPU or not. The device in the slot still works.

comment PCIe card and x8/x16 lanes
The question you link to says the opposite of what you claim: PCIe is PCIe, and there is nothing special about the PEG slot or graphics cards, so you can plug anything in there and it will work. The one thing that can be a problem on bad boards is that they disable the integrated graphics if you plug anything into the PEG slot, but the device there still works.

comment Can't create shortcuts for .com files
What you are attempting makes no sense: more.com is a 16 bit dos program that reads from stdin and writes to stdout, pausing after each screen full. Running it from a shortcut would give it no input, so it would have nothing to do.

comment External HDD disk must be turned on twice always
Try doing it within a few seconds and see if it still shows the same pattern. If not, then heat seems likely.

comment External HDD disk must be turned on twice always
Do you only let it go for a few seconds before you power cycle it again? My first thought was heat: after running for a bit it warms up then things expand and get into the right place. That's not very likely though if you cycle it very quickly.

comment How long can you read files from a flash drive if kept in a cool, dark room?
@sum1stolemyname, you can install dos and win3.1 with networking and printing in a virtual machine such as qemu.

comment Power cord blew, computer is now sporadically slow
Processors do not lower their speed if they don't get enough power. They draw the power they need, and if the PSU can't provide it, it shuts down, or failing that ( broken psu ), the system malfunctions and/or reboots. A reduced processor frequency wouldn't account for significantly long boot times either.

comment Incorrect size of image file made with dd and gzip?
@To-la120, it does not contain the same data. If you added some files, then the space where those files are located changed from whatever was there before to what is there now. Different data is different data.

comment How to delete a file that's no longer in the directory?
Of course dot is allowed; every file has one on windows. Think *.exe, *.doc, etc.

comment Anything I can do about erratic hard disk drive speeds
Seems seagate has been making some shi*t drives lately. According to their specs, this drive is only rated for 2400 power on hours ( wtf? ) and yours has 7151. Combined with all of the bad sectors, looks like the drive is shot. I guess the lesson here is don't buy seagate.

comment Anything I can do about erratic hard disk drive speeds
@BiTinerary, no, 7200 rpm is the "standard" speed these days ( well, for the last 10 years nearly now ) for desktop marketed hard drives, regardless of capacity. Drives marketed for backup, near line, nas, or low power ( like WD green/red/purple ) operate slower ( 5400-5900 rpm ). You can tell these drives because the manufacturers avoid specifying the rpm. Also drives use less than 10 watts, so even with 3 of them, that is still far less heat than you are going to get out of a busy cpu or gpu -- quite easily cooled unless they are all crammed tight with lots of cables blocking airflow.

comment Raw reading USB mass storage or SCSI
@Otheus, nope.. ECC is performed on blocks as well ( at least the reed-solomon type used in hard disks ). They are designed to correct longer bursts of errors rather than the single odd error scattered here and there ( like a hamming code ). The only way hard disk capacities have been able to scale the way they have in the last 15-20 years is by being able to correct numerous errors inherent in packing bits ever closer together, not just one bad bit in 512 bytes.

comment Raw reading USB mass storage or SCSI
@Otheus, I pointed you there to show just how common knowledge this is and how easily you could have found it had you bothered. It is clear now that you would prefer to engage in ad hominum attacks rather than actually learn something.
