• Lifting a math symbol in LaTeX

  - by Chris Conway

  I'm using the symbol \otimes as a unary operator and it's vertical alignment doesn't seem right to me. It wants to sit a bit below the baseline: and I tried using \raisebox to fix this, e.g., \raisebox{1pt}{$\otimes$}: But \raisebox doesn't seem to be sensitive to subscripts. The operator stays the same size while everything around it shrinks: The problem, I think, is that \raisebox creates its own LR box, which doesn't inherit the settings in the surrounding math environment. Is there a version of \raisebox that "respects math"?

• Rails, ActiveRecord, how to find foreign rows that are NOT there?

  - by randombits

  The title is a bit difficult to put together for this question. Say I have two models, Foo and Bar. Foo has many Bar's. Bar belongs to one Foo. How do I use Foo.find to find all of the Foos that currently have zero Bars? In SQL this would translate into something like: SELECT * from foo where id NOT IN (select foo_id from bar);

  Hi, I'm trying to figure how can I use git for multiple environments (dev-test-prod) with code promotion. I read a bit about branching but didn't understand much how can this solve my problem since I must have the ability to run all of the environments concurrently and separately from each other.

• YUI vs jQuery, for css style layouts

  - by tony

  Hi Complete novice question. I've used jQuery a bit, YUI not at all and know very little about it. I work on a website thats IE specific, we're now looking at making it cross browser. jQuery seems great at hiding the differences between browsers from a javascript point of view. However in terms of css layout is it YUI that I should really be looking at? thanks

• Port Android App to Desktop?

  - by CodeJustin.com

  I'm just wondering if it would be possible (and legal) to port an Android app to desktop? I'm creating an android game that would work well on PC too (even with the cellphone like layout) and was thinking that maybe I could 'embed' an android emulator with an installer or would that process be a bit hard for a novice Java coder?

• CSS single property classes

  - by user1490379

  As more presentational html properties get deprecated the natural response for me was to make single property CSS classes such as .text-align-left{text-align:left}. My question is, is this preferred versus inline styles? Stackoverflow actually uses quite a bit of inline styles. PS: I know this isn't really a coding question and it is likely to incite debate but stackoverflow is the largest stack exchange for code and this question does have some use for future individuals.

• Is flash's geturl(...) spiderable by google?

  - by tom

  If I made a homepage with an embedded .swf which had buttons that linked to other html pages on my website using the getUrl() function, would those links be spiderable by google? Or should I also put in text links outside of the .swf (which would ruin the design a bit)? I know a lot of people will argue I shouldn't have flash as the main content on the homepage (and their comments are appreciated), but bear in mind, that's not my question.

• which loop is faster?

  - by Mansuro

  I have this loop for (it= someCollection.iterator; it.hasNext(); ) { //some code here } I changed it to: for (it= someCollection.iterator;; ) { if (!it.hasNext()) break; //some code here } The second code ran a little bit faster in unit tests in junit on eclipse. Is the second loop faster? I'm asking because the times given by Junit are not too exact, but they give an approximate value
