comment Is it possible to dd the current disk you are booted off?
@stuartc: It would require major cooperation from the FS driver - informing the copying process of every change that has happened since the copy started, and whether it gets to a consistent state. If this is a major issue, look into filesystems which support snapshotting, such as btrfs.

comment Why do some initial webpage requests route to my router?
Perhaps your router disconnects from the internet after some period of inactivity, and only reconnects on next request? That should be configurable (and even possible to be disabled) on the router; alas, without access to it you'd be out of luck :(

Good points on using higher-level tools - tar, cpio and rsync all work within the filesystem, so this may be appropriate. dd, OTOH, works directly with disk blocks, bypassing the FS.

comment Why do we need subnet mask?
I guess we're violently agreeing with each other then :)

comment Why do we need subnet mask?
No, the problem would indeed persist. (and btw, the push for a simple networking stack is not going away - quite the contrary, getting stronger with the "internet of things": simple also means less power needed and longer battery life)

comment Why do we need subnet mask?
That works, yes - that is, when it works (additional complexity); plus you need to know where the DNS server is; chicken-and-egg problem.

comment Why do we need subnet mask?
"why not just use names like *.my.address.com for this, just naming each computer " - you mean, like, DNS?

comment Can I encrypt data in a way that it can be read normally but can't be copied or edited?
@slhck: All right then - see my answer to what is, essentially, the same question: stackoverflow.com/questions/1790190/… ; I fancy to think that one is detailed enough. Although the OP was asking about digital video data there, the distinction makes no difference here.

@Shadok: The price tag doesn't reflect the technical part - blocking writes for most modern drives is indeed technically simple (blocking changes to e.g. SMART attributes, now that's a different story). It's the "certification" business - see that "NIST Ver. 2 accepted" blurb? That's the whole point: you don't need to prove to a court that the device actually and reliably blocks writes (which can get, uh, somewhat expensive, even several orders of magnitude beyond that $800).

comment Why don't you see binary code when you open a binary file with text editor?
@Fiasco Labs: Pedantry: one hex number with two digits - 00 to FF, which translates to decimal 0 - 255 (8 bits representing 2^8 = 256 possible states).

comment How to recover a Linksys WRT54GL router that has a blinking green power LED and no response from the web interface?
Good point about the power supply - I've had an Asus WL500gP fail to boot, and it looked just like a bad flash. In the end, turned out that the wall wart couldn't give whole 2000 mA at boot (the power draw is considerably lower once the boot sequence finishes). Replacing it fixed the problem.

comment Why is dial up so slow?
Few miles? I wish. Most of the ISPs here will only guarantee something like 1/10 of the advertised speed as soon as you're more than a few thousand feet from a DSLAM. "Too much noise" and whatnot.

comment Finding router's WAN/External MAC address
@Hazar: If you wish, use a cross-over cable; it can't hurt. But honestly, almost anything has Auto MDIX these days.
