comment Does safari utilize an internal DNS cache?
"All other major browsers have some form of DNS cache" - citation-needed. MSIE in particular depends on the Windows DNS resolver (and thus, on its cache). That said, a browser vendor who is also the vendor of the underlying OS would not have a reason to build another DNS cache; whereas e.g. with Firefox, using a cache (or at least an abstraction to make various OSes behave in a similarly predictable way) this makes sense.

comment Windows 7 and cd to symbolic links
Aha! I didn't know that one comes preinstalled. Then it doesn't make sense to also install junction.exe . Thanks for the clarification!

@paradroid: junction still works, even in Win10 ;)

comment What could 'Roaming not allowed by server' of ssh client mean?
Should be chmod 400. No idea why I'd ever want that file to be executable; and write access is also not desirable 99.999% of the time. sshd checks that the user's .ssh folder has no access for group and other, and likewise for .ssh/authorized_keys. Therefore, the perms in the answer might work, but they're unnecessarily wide.

@nikeee: ...and that's a cautionary story for not shipping "harmless" non-working stubs. (Note that you need to set it to no in client settings, not on the server)

comment Do most music CDs contain the needed info about their tracks?
Quite possibly. From my usage, it found most CDs - haven't compared it with other players.

comment Do most music CDs contain the needed info about their tracks?
Yes. It's a checkbox named "Allow metadata network access." In Simple mode,in the first settings tab ("Interface"). In Expert mode, it's under Playlist . (checked on VLC 2.2.1/Windows and 2.2.0/Linux here)

comment Do most music CDs contain the needed info about their tracks?
In my experience, VLC can and does retrieve metadata from network - if allowed. VLC will prompt about internet retrieval on the very first start (for privacy reasons); if you have disallowed that, it will obey. (You can still re-enable this in settings)

comment Do most music CDs contain the needed info about their tracks?
In my experience, most CDs I have played do not contain this info (and net-capable players fall back to pulling the missing metadata from Internet, but that's beside the point).

comment Soundcard makes constant ticking or clicking sound
Wireless interference. While your router has nothing to do with sound, it surely emits radio waves (a.k.a. WiFi signal), and your soundcard acts as an antenna, picking it up.

comment Automatically reconnect interactive SSH session
Note that in some circumstances, a SSH session might simply hang instead of terminating. Autossh tries to mitigate this by pinging itself through the connection, and restarting if it looks unresponsive. However for environments where only ssh is available (or some stripped down ssh client even - embedded devices etc.), your solution would be the easiest solution.

@John Rennie: Same thing is currently implemented in the ext4 FS: ext4.wiki.kernel.org/index.php/Ext4_Disk_Layout#Inline_Data

comment Why isn't there a clone of Total Commander for OS X?
Note: I have tried using TC on Linux (via Wine), and it works quite well, including plugins. I would expect similar behavior on OS X.

comment Damaged disk, what are my options
@cybernard: "Might be" is the key word here. The other thing which also might happen is damaging your data beyond repair (for an untrained user, there's no way to tell which of these is more likely). In other words, only try to meddle with broken hard disks yourself if your data is of very low value; trying with valuable data is Russian roulette. (Disclaimer: I am not affiliated with any data recovery companies - but I have managed to destroy my own valuable data through overconfidence ;))

comment How does a browser get a website's logo?
GET /favicon.ico - a normal HTTP GET request, no magic here. You can also specify the icon in a HTML page using the meta name="shortcut icon"

comment Reverse SSH Tunneling Question
Even better, use autossh instead of ssh - it is a wrapper around ssh with additional mechanisms for ensuring that the SSH connection stays up.
