comment How do I patch the shellshock vulnerability on an obsolete Ubuntu system that I can't upgrade?
A closer analogy would be telling someone experiencing a bug in GCC to try clang. Both implement the same language (with different but sometimes overlapping sets of nonstandard extensions) and it's unlikely that the actual need is for "bash" but rather for "shell interpreter".

comment Are computers with more RAM potentially faster if not all memory is usually in use?
Part of the difficulty of this question is that "in use" is difficult to define for any modern operating system with virtual memory and memory-mapped files. For example, is the code ("text") segment of an executing program "used" or "cache"?

comment What is a external reliable IP address to ping to check if internet is available?
This question would be more answerable with some details on scope. The types of answers that might make sense for a site-local script that you can edit when necessary are going to be a lot different than the types of answers that would make sense for an embedded device (home routers, settop boxes, in-car devices, ...).

comment Why are special characters such as “carriage return” represented as “^M”?
Ascii DEL (^?) has nothing to do with the delete key. It's actually the standard code generated by the <--- key (also, confusingly, called backspace) on VT100-like terminals.

comment Why are special characters such as “carriage return” represented as “^M”?
It's not used only with letters. I would not define it as the control character with "the letter's numeric value" but rather as "xor 64". In other words, ^A is 0x41 xor 0x40, or 0x01 and ^? is 0x3F xor 0x40, or 0x7F.

comment Displaying ads over WiFi hotspot
@Chipperyman: I explained in a comment on one of the answers some of the things that could go wrong. In addition, providing modified versions of the content that users access (at least morally, and hopefully legally) nullifies his status as a common carrier. For example, as David mentioned, if one of his neighbors is downloading CP, his machines would be actively fetching, modifying, and re-serving the pages containing CP rather than just passing through packets.

If you want/need to make money you should just charge them a tiny fee for access. Otherwise, drop this. It's a bad idea.

comment Displaying ads over WiFi hotspot
As an aside/additional reason not to do this, modifying the data returned by an HTTP request can introduce serious and far-reaching corruption. Imagine a non-expert updating their website who downloads their own page, modifies it, and uploads the resulting html file back to their server via ftp. You've now trashed their data; your modifications inadvertently make it back out into the wild. There are plenty of other variants on this theme.

It's not my computer and I don't have access (much less local access) to it, but I'll pass along your comments and see if anything turns up.

comment Identifying program attempting to install certificate on windows
Starting in safe mode and running a system restore made the problem go away, hopefully for good. But that didn't really answer the question. I'd still like to know, in general, if there's a way when system-level warning/confirmation dialogs like this appear, to determine the identity of the program that's causing them.
