  • temporarily change fonts in latex with T1 font

    - by georg raba
    Hello, I want to temporarily change fonts in latex, to arev. Usually, this would work, as described here: {\fontencoding{T1}\fontfamily{arev} the font is temporarily changed} it doesnt though, and I think it has to do with the fact that arev is a T1 font. I think I need to specify more? Thanks in advance for any advice, I appreciate it! Georg Raba

  • How do I open iPhone camera and restrict to a frame?

    - by Thomas
    Hello All: I'd like to know how to open the camera inside of a pre-defined frame (not the entire screen). When the view loads, I have a box, and inside it, I want to display what the camera sees. I don't want to snap a picture, just basically use the camera as a viewfinder. I have searched this site and have not yet found what I'm looking for. Please help. Thanks! Thomas

  • C array assignment and indexing with similar variable.

    - by Todd R.
    Hello! I apologize if this has been posted before. Compiling under two separate compilers, BCC 5.5 and LCC, yields 0 and 1. #include <stdio.h> int main(void) { int i = 0, array[2] = {0, 0}; array[i] = ++i; printf("%d\n", array[1]); } Am I to assume not all compilers evaluate expressions within an array from right to left?

  • Divide and conquer method to compute roots [SOLVED]

    - by hellsoul153
    Hello, Knowing that we can use Divide-and-Conquer algorithm to compute large exponents, for exemple 2 exp 100 = 2 exp(50) * 2 exp(50), which is quite more efficient, is this method efficient using roots ? For exemple 2 exp (1/100) = (2 exp(1/50)) exp(1/50) ? In other words, I'm wondering if (n exp(1/x)) is more efficient to (n exp(1/y)) for x < y and where x and y are integers.

  • Advantages/disadvantages of browser-based interface vs. graphics

    - by Josh
    Hello everyone, I'm in the design phase for a desktop-based application. Because of the nature of this particular application, I believe it would benefit greatly from a web-based approach (i.e., allowing a user to interface with the application through a browser running in kiosk mode) in order to leverage the simplicity of HTML/CSS/JS and the availability of many great JS interface plugins. Does taking this approach (rather than coding in a native or cross-platform graphics library) come with any gotchas?

    - by Leo
    Hello, is it possible to specify that a NSMutableArray can only contain a certain type of objects. For example, if I want to store only this kind of objects : @interface MyObject : NSObject { UInt8 value; } In order to be able to use the instance variable like this : - (void)myMethod:(NSMutableArray *)myArray{ for (id myObject in myArray){ [self otherMethod:myObject.value]; } } because I'm getting this error : request for member 'value' in something not a structure or union Thank you for your help

  • Regex to extract a string between two delimeters WITHOUT also returning the delimeters?

    - by CSharp Noob
    Hello, I want to just extract the text between the brackets -- NOT the brackets, too! My code looks currently like this: var source = "Harley, J. Jesse Dead Game (2009) [Guard]" // Extract role with regex m = Regex.Match(source, @"[(.*)]"); var role = m.Groups[0].Value; // role is now "[Guard]" role = role.Substring(1, role.Length-2); // role is now "Guard" Can you help me to simplify this to just a single regex, instead of the regex, then the substring?

  • Scrapy - Follow RSS links

    - by Tupak Goliam
    Hello, I was wondering if anyone ever tried to extract/follow RSS links using SgmlLinkExtractor/CrawlSpider. I can't get it to work... I am using the following rule: rules = ( Rule(SgmlLinkExtractor(tags=('link',), attrs=False), follow=True, callback='parse_article'), ) (having in mind that rss links are located in the link tag). I am not sure how to tell SgmlLinkExtractor to extract the text() of the link and not to search the attributes ... Any help is welcome, Thanks in advance

  • Pylons error handling

    - by TJ Huffington
    Hello, I am just getting started with Pylons and am confused as to how to account for exceptions. What is the proper way to error check user input (ensure a correct email address, check that it doesn't yet exist in the database, etc ...)? Should these checks go inside the model classes or somewhere else? Sample code would be great.

  • In paragraph form field with label underneath

    - by aslum
    I'd like to have an input box in the middle of a paragraph, with the label in smaller text underneath it. Kind of like: Hello [________________], This is to inform you (Customer Name) that the [____________] you ordered is no longer (Item Name) available. I thought it would be pretty easy to do, but my brain doesn't appear to be working today. Is it possible to do this with just CSS, and in a simple enough manner that it can be adapted to different forms easily?
