I tried to answer a question and putted: "&lt; ? php" (no blanks between it) into a answer here in stackoverflow. But it does not work; i read about the advanced formatting but did not find the hint or explanation how to solve this.  Surely someone will know this.
How do I post text so that it is formatted as code?  What do I need to do so that my code shows up properly &mdash; not escaped or removed &mdash; when posted? And how to get the correct syntax highlighting?     For more information, see "" in the .

Cannot get 2 raster files of same cell size to align ArcMap 10.2 Pollinator abundance---sampled two years, fixed or random effect? I'm trying to construct several GLMMs with my thesis data and I can't solve this question. I have data on pollinator abundance and fruit set from plant individuals (with different treatments - related to a pest infection -) sampled at six study sites (spatial replicas) and during two consecutive years (time replicas). The problem is that not all individuals (plants) were sampled in both years (because of lack of bloom). My question is: How should i use &quot;Year&quot;, as random effect or as fixed effect? I constructed three candidate models and compared the AIC: a) Response variable ~Predictor variables + (1 | year/plant) + (1 | site/plant) b) Response variable ~Predictor variables + (1 | year) + (1 | site/plant)  c) Response variable ~Predictor variables * year + (1 | site/plant) Option a) had the lowest AIC and the highest R2, but I read in some papers that is not correct use a variable with less than five levels as random effect ... so, anyone could help me? Why does every server I try say it can't connect? I just re-purchased Minecraft (because my old profile stopped working so I bought it) after not playing it for a couple of months. I've added a bunch of servers, but almost every one says "can not connect."  I know its not because the server is not 1.7.2, because I checked that they'd update. It will say "server can't connect" after a long time. I don't know if its me or the servers.  My server screen looks like this (notice the one at the bottom – it's still loading!): Making dual power supply from single for opamp? For the circuit of opamp 741. we have to supply the dual power for it. How can I make a dual power supply from single. For example, make a (+9V)-GND-(-9V) from single 9V battery ? Here's my code:  x = 1.0 y = 100000.0     print x/y   My quotient displays as 1.00000e-05.  Is there any way to suppress scientific notation and make it display as 0.00001? I'm going to use the result as a string. This is my attempt to prove that, if $a &gt; 0$, then $\frac{1}{a} &gt; 0$, using just field and order axioms.  $$a &gt; 0 \implies a \cdot \left(\frac{1}{a}\right)^2 &gt; 0 \cdot \left(\frac{1}{a}\right)^2 \implies a \cdot \left(\frac{1}{a}\right)^2 &gt; 0 \implies a \cdot \left(\left(\frac{1}{a}\right) \cdot \left(\frac{1}{a}\right)\right) &gt; 0$$  By associativity of multiplication:  $$\left(a \cdot \left(\frac{1}{a}\right)\right) \cdot \left(\frac{1}{a}\right) &gt; 0$$  We know that $a \cdot \left(\frac{1}{a}\right) = 1$, because one is the multiplication inverse of the other.   So we have:  $$1 \cdot \left(\frac{1}{a}\right) &gt; 0 \implies \frac{1}{a} &gt; 0 $$  Which is what we wanted to prove.   My question are:    In the field axioms, there's no axiom that says that $0$ times another number is $0$, but I have used this property. How would you translate it to field and order axioms? I have assumed that $\left(\frac{1}{a}\right)^2$ is positive, have you noticed? Note that I need a positive number in order not to change the $&gt;$ sign. But this is not present in the field or order axioms. How would you explain this? How to check a large backpack? When travelling on airlines based in the US with a large backpack, I prefer to carry the bag onto the plane as part of my hand baggage allowance.  Most foreign flag carriers, however, have a significantly more restrictive hand baggage allowance.  I was caught off guard by this one time on New Zealand airlines and received my backpack with multiple broken straps and clips.  I managed to repair it, and I'm still using the same pack, but I would like to avoid so many broken parts in the future.    Once, when flying Alitalia (flight was actually booked through Delta) I carried plastic wrap to the airport, and wrapped the entire bag in it before handing it over to the airline.  @jpatokal recommends putting it into a giant, heavy-duty garbage bag in his answer to .     What are the pros and cons of using plastic wrap or a garbage bag?   Can anyone recommend any other, more effective techniques? Is there a way to get the count of rows in all tables in a MySQL database without running a SELECT count() on each table? math fallacy problem: $-1= (-1)^3 = (-1)^{6/2} = \sqrt{(-1)^6}= 1$? I know there is something wrong with this but I don't know where. It's some kind of a math fallacy and it is driving me crazy. Here it is: $$-1= (-1)^3 = (-1)^{6/2} = \sqrt{(-1)^6}= 1?$$ how to Query parent to child I have process in salesforce in such a way opportunity we can relate this opportunity to this lookup field parent_opportunity__c . Which relates opportunity to other parent opportunity.  I want to write a query parent to child :  select id,(select id from opportunity where parent_opportunity__c!=null) from opportunity where parent_opportunity__c=null   I have worked with different scenarios i cant able to crack it  select id,name,(select id,name from parent_opportunity__r) from opportunity this is showing error and   select id,name,(select id,name from opportunity) from parent_opportunity__c this is also error Why is fundamental group insufficient to classify manifolds? How can I set the drawableRight resource via code? I have a large table that is already partitioned by an identifier (CustomerId). I have created new customers, and want to add new partitions to the table, and want to confirm the correct way to do this. My predecessor set this up and is no longer available so I cannot confirm.  There are currently partitions for 60 distinct CustomerIds (let's say 1-60), and a filegroup and file for each. I have created new filegroups and files for the new customers (61-68) and need to partition the existing data already in this table. So, the data that's already in the table, with customerId 61-68 needs to be moved into separate partitions.   I tried to use the partition wizard, but couldn't find an option for what I wanted. As far as I can tell, I need to run something like:  ALTER PARTITION SCHEME PS_Details  NEXT USED Filegroup61 ALTER PARTITION FUNCTION PF_Details ()  SPLIT RANGE (61)   I'm looking for someone to point me in the right direction as to best practice for this sort of thing. Do I take the data out of the table, into a new table stored in the Filegroup61 then switch the partition in? Not really sure how to approach this. Consider $X = (a+b)^n-a^n-b^n$  where  $a$ and $b$ and $a+b$ are not divisible by $n$, $n&gt;=3$ is positive and prime, $a \ne b$ and both are greater than 1.  By the binomial expansion we know $X$ is divisible by $n$, but how can we study whether $X$ is divisible by $n^2$ or other powers of $n$? Specifically I am interested to prove $X$ is NOT divisible by $n^2$, but I am not sure how to prove or disprove it. When I need to generate unique id's based on some information hashing is typical choice. However, sometimes that id needs to be of a particular size.  I've seen a lot of schemes (HMAC-MD5-96 in SSH, CGA in SeND for IPv6) that use a portion of a hash, so I'm thinking it might be alright to use it that way.    Which properties of a hash are preserved and which do not apply anymore?  Obviously, with less bits, the chance of collision goes up, but can I still rely on the partial hash for uniform character distribution?  What about the ?  I'm guessing that if a hash modifies the entire hash upon the smallest change to the input, that would imply that a portion of that hash would be equally well changed.  Am I thinking about this correctly?  Also, would these behaviors be different for different hashing algorithms? Can I recover a file from /dev/null? What is a word for deliberate dismissal of some facts? Night's Watch deserters are sentenced to death, as we've seen in the very first episode of Game of Thrones. A man dressed all in black is apprehended by Stark men and brought before Lord Eddard Stark. Lord Stark sees him as a deserter and sentences him to die (and then executes that death penalty).  However, there are men of the Night's Watch south of the Wall, on a legitimate mission or on some kind of allowed leave. For instance, we have Benjen Stark visiting Winterfell when the king and his party is there. There is also Yoren, who travels around Westeros in search of new recruits.  I could imagine that the Warden of the North (and other lords in the northern part of Westeros) would have a good idea of who would be allowed further south and whose appearance would raise suspicion. But I reckon the southern lords don't have as many visits from the Night's Watch, so they might not know who would be allowed to be there and who wouldn't.  How would lords who are rather unfamiliar with the specific brothers of the Night's Watch discern deserters from brothers sent out for some reason?  That ends my question, but there is a spoiler from the season 5 finale that continues the question a bit more:      Sam is sent to Oldtown to become a Maester, so he can replace Maester Aemon at Castle Black.  But he is riding together with Gilly (a woman!) and her baby (a baby!), which might raise a lot of suspicion from people who don't know what he is sent out to do.  What prevents southern lords of sentencing Sam as a deserter from the Night's Watch?
