Iterating through columns in table using ModelBuilder? I am unable to find any info on how to use ModelBuilder to run a certain spatial analysis function on each column in a table.  I have a table to sample locations and at each location there are a series of measures (e.g. temperature, flow rate, number of certain species).  For each of those attributes (columns in the table), I was to run the IDW function from the surface tools.  This would be easy if I had each attribute in a separate shp/feature class, but not very efficient.  I tried Iterate Feature Selection, but was unable to pass the field name as the Z value in the IDW function.  This is for ArcGIS 10.1 (Basic and Spatial Analyst license) I'm a college student and I just got my first credit card (through Chase). The only reason I got the card is to try and build my credit score. I also have a checking account with Chase, and they let me pay off my credit card any time I want.  For example, right now I have a balance of $92 on my credit card, but my bill won't come until September 2, and the payment isn't actually due until September 27. But through their website I could go ahead and pay it off with money from my checking account.  My question is, is it better for my credit score if I pay off that $92 balance right now, or should I wait for the bill, or does it not matter either way? Beamer: Blackboard theme and overlays I am currently preparing my beamer presentation for my PhD defense.  I took the example at the url  to get a black board style presentation.  This template includes a short script which uses a random-generator to randomly scatter dust-trails on the black background to mimic chalk traces (see MWE below).  The thing is that parallel to that, I am also using overlays to uncover my slide layout by layout. The script is executed each time I am using a layout command which slows down the compilation quite substantially. I am not so familiar with control statements in latex, so here is my question:  How can-I modify this script for the background to be refreshed only when the slide is over, and not after each layout command?  Remarks:  1) I am using the Augie font, but I didn't included it in the MWE so that it can be compiled more easily  2) In case, it should make a difference I am also using the \begin{textblock*} \end{textblock*} environment from the textpos package to position text on the slide.

Thanks in advance,  Yannick random access file in java I have the following fields:   Inventory control (16 byte record)   Product ID code (int – 4 bytes) Quantity in stock (int – 4 bytes) Price (double – 8 bytes)    How do I create a fixed length random access file using the above lengths? I tried some examples online, but I either get an EOF exception or random address values when I try to access them.  I tried some more examples and couldn't understand the concept very well. I'm trying a project with it and will try to explore more on it.  Here is some example data. There might be holes in the data where No. in stock could be 23 == 023.            Quantity ID.

For macro photography, how do I choose between a compact camera or a mirrorless interchangeable-lens camera (without considering a lens)?   What indicator(s) should I look for when making the choice? What if the answers of a historical locked question become obsolete? My understanding is that a question is historically locked because the information in it is too valuable for the question to be deleted.   But if the "valuable information" becomes obsolete, what happens then?  We cannot modify the question content, or the answers for a historically locked question, right? When installing Wine on 64-bit Ubuntu 12.04, both 64-bit support and 32-bit support get installed. If I run wine foo.exe where foo.exe is a 64-bit-aware installer, it thinks it's on 64-bit Windows. This would be fine if this mode didn't fail, but in my case, it does (yet the Wine database suggests the app I'm trying to install should work, presumably as a 32-bit app).  How do I tell Wine (and Winetricks) to use Wine in 32-bit-only mode? Can somebody help me to prove this identity?     $$\prod_{k=1}^{n-1} \left(\;\cos\theta-\cos\frac{k\pi}{n}\;\right) = 2^{1-n}\sin(n\theta)\csc\theta$$   I was thinking of using the properties of the complex numbers and the binomial theorem, because I found this problem in the Complex Variables book from Schaum's, but it did not solve my problem.  Does anyone have an idea?  Thanks in advance! I would like to change the caption in the List of Tables in a way it is different from the caption in the corresponding table. How can I do that? Does there exist a command to do that? Oven Temperature: How to be sure the selected temperature is correct. I suspect that my - fairly new - oven gets too hot, so I bought an oven thermometer, which confirmed this.  So I called the supplier.  They say that in order to obtain the correct actual  oven temperature, for any setting, you take the highest reading on the thermometer, and the lowest, and then divide both readings.   Is this correct? Is it possible to install an app and exclude some of its requested permissions? Occasionally I want to install an application which requires certain permissions that I feel it really shouldn't need. Can I install the app without giving it these permissions? For example, GPS location, , internet connection, etc.  Is it possible to change the permissions of an application once it is installed? Sometimes, I write the name of an author in a sentence before the citation. For this reason, I'd like to suppress it in the citation. How can I do that?  Is the only solution to create a new macro, e.g. \citewoauth, similar to \cite but without author names, or am I missing something? [The MWE (non-working actually) below is with \parencite but the general idea is similar.]    \begin{filecontents}{\jobname.bib}   @article{doe_2011,     title = {A title},     author = {John Doe},     journal = {Journal},     number = {99},     pages = {483--488},     date = {2015},   } \end{filecontents}  \documentclass[12pt,a4paper]{article} \usepackage[utf8]{inputenc} \usepackage[french]{babel} \usepackage[T1]{fontenc} \usepackage{csquotes} \usepackage[style=verbose-trad2,language=french,backend=biber]{biblatex}  \addbibresource{\jobname.bib}  \begin{document} Some text\footnote{According to John Doe, it is \enquote{a complete nonsense} \parencite[485]{doe_2011}}  \printbibliography \end{document} CodeIgniter/PHP Active Record won't increment an integer Repeat the same reference in footnote on different pages Using Regex to generate Strings rather than match them How can I make an InputField with a proper newline/carriage return? What is the correct way to edit a crontab file? I was asked this question during an interview for a trading position with a proprietary trading firm. I would very much like to know the answer to this question and the intuition behind it.  Amoeba Question:  A population of amoebas starts with 1. After 1 period that amoeba can divide into 1, 2, 3, or 0 (it can die) with equal probability. What is the probability that the entire population dies out eventually? In Bash, two integers can be compared using conditional expression     arg1 OP arg2      OP is one of -eq, -ne, -lt, -le, -gt, or -ge. These   arithmetic binary operators return true if arg1 is equal to, not equal   to, less than, less than or equal to, greater than, or greater than or   equal to arg2, respectively. Arg1 and arg2 may be positive or negative   integers.   or arithmetic expression:     &lt;= &gt;= &lt; &gt; comparison      == != equality and inequality   Why do we have two different ways for comparing two integers? When to use which?  For example, [[ 3 -lt 2 ]] uses conditional expression, and (( 3 &lt; 2 )) uses arithmetic expression. Both returns 0 when the comparison is true  When comparing two integers, can these two methods always be used interchangeably? If yes, why does Bash have two methods rather than one?
