I have a simple 2-column layout with a footer that clears both the right and left div in my markup.  My problem is that I can't get the footer to stay at the bottom of the page in all browsers.  It works if the content pushes the footer down, but that's not always the case.
Is it possible to install Windows from an external hard drive?  I have Windows XP installed on my laptop, and I want to remove it and install Windows 7.  My Windows 7 installation is in an .iso format on an external USB hard drive.  Is it possible to install it or will I need to put in a DVD before I start installing? How do you list the primary key of a SQL Server table? How do I check OS with a preprocessor directive? What’s the real-world origin of the name Azor Ahai? Azor Ahai is some mythical hero, who may or may not coincide with other mythical heros that are supposed to be born and save us from the eternal night (which is dark and full of terrors, if we are to believe Melisandre).  But I'm interested in the origins of the name, here, in our world. More specifically because in Hebrew "Azor Ahai" means (albeit ungrammatically) "Help my brothers", or if you transliterate it differently you'd get "The Living Help".   Since writers often take meaningful names to be terms from other languages (and mangle them a bit), I can't help but wonder Did GRRM reveal the origin of the name "Azor Ahai" at some point? How to use siunitx with non numerical values? I understand that something like \SI{5}{\meter\per\second} defines a certain space between the number (5) and units (m/s). What should I use if instead of a numerical quantity I want a variable: R m/s? \SI{R}{\meter\per\second} fails because it expect a number in first parameter, and R \si{\meter\per\second} or $R$ \si{\meter\per\second} show different space.  Which is the correct use?  \documentclass{standalone} \usepackage{siunitx} \sisetup{per-mode=symbol} \begin{document} \begin{tabular}{r} \SI{5}{\meter\per\second}\\ $R$ \si{\meter\per\second}\\ R \si{\meter\per\second}\\ \end{tabular} \end{document} You can't see the question owner's special color The only solution that I have been able to come up with is $d=1$, but because $d&gt;2$, I can't seem to figure out how to find a solution. Do the electric and magnetic components of an electromagnetic wave really generate each other? Frequently when EM waves are taught, it is said that the change in electric field causes a change in the magnetic field, which then causes a change in the electric field, and so on and so forth.   But from my understanding of basic electromagnetics, it is not necessarily a changing electric field that creates a change in magnetic field, but instead an accelerating charge. and it is this charge that creates both the electric and magnetic field. Again, from my understanding, a changing magnetic field is not generated by a changing electric field, but instead just happens to always be present perpendicular to a changing electric field due to the laws of electromagnetism.   Am I wrong? Or is the "mutual generation" concept between the electric and magnetic components of an EM wave an actual thing? Does a List guarantee that items will be returned in the order they were added? Does a List&lt;T&gt; always guarantee that items will be returned in the order they were added when enumerated?  Updated: Thanks for all the answers folks, puts my mind at ease. I had a quick poke around the List&lt;T&gt; class with .NET Reflector (should've probably done that in the first place) and indeed the underlying store is an array of T (T[]). I just bought all the ingredients to make a soup in the crock pot. I was planning on having it cook all day, but I just realized the recipe only calls for it to cook on low for 3-4 hours. If I cook it on low for 3-4 hours, and then put it on warm before I leave for work, will it be a bacteria minefield or will it be warm enough to keep the food safe from bacteria? We sometimes buy trout from a local breeder who'll get them fresh out of the water for us, and then cook them a few hours later. They taste great, but the flesh tends to fall apart in a way that doesn't happen with fish from the super market. It's often barely even possible to get them out of the pot without them completely coming apart. We tried leaving them in the fridge for a day so they wouldn't be quite as just-killed-an-hour-ago-fresh, but that didn't help.   We usually prepare them by cooking them in simmering (not boiling) water.  Is there some way to prevent this? Is it generally true that if $|P(A)|=|P(B)|$ then $|A|=|B|$?  Why? Thanks.

Managing constructors with many parameters in Java In some of our projects, there's an class hierarchy that adds more parameters as it goes down the chain. At the bottom, some of the classes can have up to 30 parameters, 28 of which are just being passed into the super constructor.  I'll acknowledge that using automated DI through something like Guice would be nice, but because of some technical reasons, these specific projects are constrained to Java.   A convention of organizing the arguments alphabetically by type doesn't work because if a type is refactored (the Circle you were passing in for argument 2 is now a Shape) it can suddenly be out of order.  This question might be to specific and fraught with "If that's your problem, you're doing it wrong at a design level" criticisms, but I'm just looking for any viewpoints. I have this MySQL query using  that is the following:  SELECT *  FROM data_tbl WHERE AES_DECRYPT(data_point,'aBcDeF')='data_1';   I've figured out as much that the equivalent in Postgres 11 is  (F.25.4. Raw Encryption Functions) and the query would look something like this:  SELECT *  FROM data_tbl AND decrypt(data_point,'aBcDeF','aes')='data_1';   At least, the documentation for both leads me to believe that these are equivalent.  The data was dumped from MySQL and imported into PostgreSQL.   The data-point field in MySQL is type varbinary(255) and the values all show BLOB in MySQL Workbench.  The data_point field in Postgres is type bytea and the values all show [binary data] in pgAdmin.    Whether those data types are equivalent, I admit, I'm not sure.  The MySQL query works and finds a record based on he criteria. The PostgreSQL does not, although the record is in there. So it seems like one of three things:   The data types (varbinary(255) vs bytea) are not equivalent The data does not match (BLOB vs [binary data]) are not equivalent The functions (AES_DECRYPT vs decrypt()) are not equivalent   I did try to decrypt the value in PostgreSQL just to see what it is in a readable format by first trying:  SELECT decrypt(data_point, 'aBcDeF', 'aes')  FROM data_tbl;   But that just returned [binary data] for all the rows.  Then I came across  to use convert_from as in:  SELECT convert_from(decrypt(data_point, 'aBcDeF', 'aes'), 'SQL_ASCII') FROM data_tbl;   However, I just get this error:  ERROR:  invalid byte sequence for encoding "UTF8": 0xcf 0xf5 SQL state: 22021   So at this point I'm stumped as to how to resolve the primary issue. The primary issue being doing the equivalent of AES_DECRYPT but in PostgreSQL 11. The last error message isn't so much an issue, but it is likely related to decrypt() not returning the same results.  Any suggestions? Asking days badges A couple of months ago, I suggested a set of badges for . The responses were... mixed. The  can be summarized:  In practice, all this would do is encourage people to ask yet more stupid, worthless questions and we have quite enough of that as it is.  We believe that one of the main things holding back many of our beta sites is that when people have questions they aren't in the habit of asking on the site. Even our flagship site, Stack Overflow, doesn't get many questions from its most knowledgeable users. Perhaps they don't have questions, but far more likely they find answers without needing to ask. Our subtle bias against asking (questions =&gt; clueless) means we lose out on what might be our best source of excellent questions. So we went back to the drawing board and designed a badge set that should not encourage worthless questions:  Asked a well-received question on X separate days, and maintained a positive question record.  In order to award badges, we need to define our terms:  positive question record   (total questions - negative questions - closed - deleted)/total questions &gt;= 0.5  It triple counts a question that is downvoted, closed, and deleted. If you ask one that hits that trifecta, you'll need to ask three better questions to dig yourself out. My own record of asking does not meet the criteria:   (44 - 0 - 12 - 12)/44 = 0.4545...  My  looks a lot better; I had a bunch of questions from the beta period that have been subsequently (and rightfully) deleted. With care, I could bring my record into positive territory with 4 questions. The takeaway is that people can't sweep past indiscretions under the rug by deleting them. And they can recover from a bad start as long as they don't ask more bad questions.  well-received question on X separate days A well-received question is one that's open, not deleted, and has a score &gt; 0. If you ask at least one well-received question in a  and none of your questions that day are deleted, downvoted, or closed, you get one more day of credit toward the badge. Whenever the badge criteria is checked, previous asking days are re-evaluated so that there's an incentive to fix downvoted and/or closed questions. The no-deleted-questions criteria is to prevent people from asking several questions at once and deleting any that aren't upvoted or answered to ask another day. (Though this is a losing strategy in the long run.)   My proposed badge names and levels:  Asked a well-received question on 5 separate days, and maintained a positive question record.  Asked a well-received question on 30 separate days, and maintained a positive question record.  Asked a well-received question on 100 separate days, and maintained a positive question record. In addition, since some outstanding individuals ask on more than 100 days, the gold badge may be awarded multiple times. Over on English, Oishi-sama (now a ) would have a remarkable . Bronze and silver badges are only awarded once. We've decided to hold off on multiple awards for now. See the . Neither the names nor the levels nor even the descriptions are set in stone. Please play around with  to get an idea of how the badge works using our public data. Since the query does not account for deleted questions, it's a bit more generous than the actual badges would be. This version of the badge set should encourage a habit of well-received questions over time and encourage people to fix poorly received questions.  I'd like to express my gratitude to the Parenting community for participating in our . Why does the CRT formula yield a solution of a congruence system? SQL Server Dependencies Is there an easy way to chase down table/stored procedure/function dependencies in SQL Server 2005+?  I've inherited a giant application with lots of tables and even more stored procedures and functions that are long and interlinked.    At the end of the day is there a way to build a dependency tree?  Ideally what I'm looking for goes in both directions:  For a table/procedure - what depends ON it?:  Show me all the stored procedures that eventually reference it (ideally in a tree view such that sub procedures nest out to the bigger procedures that call them)  For a procedure - what does IT depend on?:  Show me all the procedures and tables that a given procedure will (or could) touch when running.  It seems this tool shouldn't be that hard to make and would be incredibly useful for DB maintenance generally.  Is anyone aware of such a thing?  If this doesn't exist, why the heck not?
