What would you call an algorithm that lets you put arbitrary data in an arbitrary order relative to each other, like a doubly linked list, but also gives you constant-time comparison between list nodes that returns the order you put them in?  It needs to have better asymptotics for changing/adding to the order than an array/vector.

After one too many times of not being able to show people the video that may change how you hear the phrase "change the world" forever, I recorded and YouTubed it.  It's from the GPL'ed game "Fish Fillets" and is, like the game, full of oddball humor. http://youtu.be/Uo7Y_bDhnZY

Security/Vagrant folks: why should I believe that "vagrant init precise32 http://files.vagrantup.com/precise32.box" can't let a MITM pwn my VM?  I haven't found documentation of Vagrant's security architecture yet.

+Patrick Wheeler : The problem is that you can be pwned just by using it for development, unless I hear detailed reasons otherwise.  On the surface it looks like it's fetching a VM by unauthenticated HTTP (the fact that it redirects to HTTPS on another server doesn't help: an attacker could hijack the initial redirect).

Bug in Google Groups used as mailing-list:

1. Using email address A, email "subscribe" to pandoc-discuss+subscribe@googlegroups.com
2. receive confirmation-request reply to A
3. reply from A to confirm
4. get confirmation to A that I have joined

So far so good.

5. start receiving list email to an entirely different email address B!  That is not proper mailing-list behaviour.

Specifically, B is my primary Google Account address, not the address that I subscribed to the list.  Does Google consider this behavior a bug?  Yes, you can configure it using a web interface afterwards, but the great thing about mailing lists is that you don't have to.

(What's a good alternative for hosting a small FOSS mailing-list? I checked a year ago and didn't find anything better than Google and self-hosted Mailman.)

I wish I could set `htop` to show RAM usage in absolute units rather than %.  Mentally comparing processes between different boxen that have much different RAM is tricky!

Is it possible to obtain an Android "recovery image" (e.g. ClockworkMod, TWRP) authenticated by at least SSL/TLS or GPG?

Neither download2.clockworkmod.com nor techerrata.com have (correct) SSL certificates.

Does Ruby have an analogue of http://docs.python.org/3/reference/index.html ? Ruby's wikibook's reference is incomplete; for example, for "case" it misses the "when 'foo', 'bar'" syntax.  Ruby's ISO standard is $250.  Still looking.
The Python Language Reference¶. This reference manual describes the syntax and “core semantics” of the language. It is terse, but attempts to be exact and complete. The semantics of non-essential built-in object types and of the built-in functions and modules are described in The Python Standard ...

If you, like so many of us, have been tinkering with the #Haskell programming language, these are some learning resources I know: http://www.idupree.com/2014/learning-haskell
Resources for learning Haskell. Haskell is a functional computer programming language. It's pretty neat and pretty useful. As I got better at Haskell, I got better at thinking about code in other languages too. These are some resources for learning Haskell: ...

I just made a StackOverflow edit to fix a bit-rotted link, but the edit was forbidden because the change was "less than 6 characters".  There were no other improvements the answer needed.  I added a pointless "www." to the link to get around this restriction, but maybe I should have honored SO's preference for remaining broken in small ways?

+Sam Auciello : there's nothing listed between 250 and 500 rep on https://stackoverflow.com/help/privileges so I guess our interfaces are the same.

Thinking about how ./configure is a ten thousand line auto-generated script that nobody reads.

It's like a portable binary that even script kiddies can edit.

I wonder why my banks have more Online Banking downtime than most of the websites I use.  It's scheduled downtime.  They're medium to large banks.

I suppose that any routine maintenance they do requires more stringent testing due to their handling financial data but I see no reason why they shouldn't be able to use a normal develop/test/deploy cycle.  I suppose they would rather be down than potentially faulty..
