• Google map - How to escape charaters in the title of a marker in a google map?

  - by Anthony

  Say have this piece of code: var marker = new google.maps.Marker({ position: location, title: 'B&#250;fals', map: map }); This creates a marker as expected but if I hover the mouse over it I don’t see 'Búfals' as I would expect (instead I see the html code). This doesn't make any difference: var marker = new google.maps.Marker({ position: location, title: unescape('B&#250;fals'), map: map }); Any ideas? Thanks.

• Bash variable kills script execusion

  - by Kyle Terry

  Sorry if this is better suited at serverfault, but I think it learns more towards the programming side of things. I have some code that's going into /etc/rc.local to detect what type of touch screen monitor is plugged in and changes out the xorg.conf before launching X. Here is a small snippet: CURRENT_MONITOR=`ls /dev/usb | grep 'egalax_touch\|quanta_touch'` case $CURRENT_MONITOR in '') CURRENT_MONITOR='none' ;; esac If one of those two touch screens is plugged in, it works just fine. If any other monitor is plugged in, it stops at the "CURRENT_MONITOR=ls /dev/usb | grep 'egalax_touch\|quanta_touch'." For testing I touched two files. One before creating CURRENT_MONITOR and one after CURRENT_MONITOR and only file touched before is created. I'm not a bash programmer so this might be something very obvious.

• Client server architecture question

  - by Shane Fulmer

  I am working on a client server system, and am running into issues where multiple clients are executing an action at the same time. We are able to solve this by locking on the critical section of code, which ensures that the first client will complete the action before the second client enters the code block. My question is this: our server is also clustered, so multiple instances of the server itself can exist, which recreates the same problem as before. How could we solve this problem? Thanks!

• Confused about NoMethodError in Ruby

  - by E L

  In a simple Ruby example, I'm getting an error that does not occur in irb. name = "Joe" def say_hi "\"Hi there!\" said #{self}" end response = name.say_hi puts response This code should return, "Hi there!" said Joe. It works perfectly fine in irb. However, when I attempt to put the same code in a file and run the file, I get this error: say_hi.rb:8:in `<main>': private method `say_hi' called for "Joe":String (NoMethodError) Any suggestion about why this happens?

• C sharp: read last "n" lines of log file

  - by frictionlesspulley

  need a snippet of code which would read out last "n lines" of a log file. I came up with the following code from the net.I am kinda new to C sharp. Since the log file might be quite large, I want to avoid overhead of reading the entire file.Can someone suggest any performance enhancement. I do not really want to read each character and change position. var reader = new StreamReader(filePath, Encoding.ASCII); reader.BaseStream.Seek(0, SeekOrigin.End); var count = 0; while (count <= tailCount) { if (reader.BaseStream.Position <= 0) break; reader.BaseStream.Position--; int c = reader.Read(); if (reader.BaseStream.Position <= 0) break; reader.BaseStream.Position--; if (c == '\n') { ++count; } } var str = reader.ReadToEnd();

• Adjust Title Helper in Ruby on Rails Tutorial 3.2 to deal with & properly

  - by memoht

  I am using the title helper from the 3.2 edition of the Ruby on Rails Tutorial by Michael Hartl and just realized a snag with the & character showing up in the title as &Amp instead. The relevant snippet of code is here Official Sample App 2nd Edition The problem. I have a School model and am using the School name on the Show view as follows: <% provide(:title, @school.name) %> If my School has a & in the name, it is being replaced with &Amp in the browser title. Ryan Bates Railscasts site has a similiar title helper that solves this issue this way but it is using content_for instead of provide. Trying to adjust the Rails Tutorial helper, but having trouble getting it work properly. Works great expect for this issue.

• Create a new output file in ant replace task

  - by Sathish

  Ant replace task does a in-place replacement without creating a new file. The below snippet replaces tokens in any of the *.xml files with the corresponding values from my.properties file. <replace dir="${projects.prj.dir}/config" replacefilterfile="${projects.prj.dir}/my.properties" includes="*.xml" summary="true"/'> I want those *.xml files that had their tokens replaced be created as *.xml.filtered (for e.g.) and still have the original *.xml. Is this possible in Ant with some smart combination of tasks and concepts ?

• Is there an easy way to change iPhone Application Settings from within an application?

  - by Matt

  I've got application settings working just fine. However, I'd like to be able to change my app settings from within my app. It seems as though there should be some kind of generic way to add this functionality to my app without having to recreate all the controls myself. I mean, the code is already written in apple's settings app. Maybe someone wrote this code and open sourced it? (if it is not already available)

• How to change aif to be able to access 'it' within the macrocall without making 'it' public in the package

  - by Sim

  If you put the aif code presented in onlisp in a package and try to use it in another you run in the problem that packagename:it is not external. (in-package :packagename) (defmacro aif (test-form then-form &optional else-form) ‘(let ((it ,test-form)) (if it ,then-form ,else-form))) wanted call syntax (in-package :otherpackage) (aif (do-stuff) (FORMAT t "~a~%" it) (FORMAT t "just got nil~%")) How can I fix this behavior in code, without making the variable it external in the package declaration and beeing able to access it just by it instead of packagename:it?

  It is easy enough to create a command from my OnLoaded() event handler code, but how do I call it from the View? <window Loaded="onLoaded"> doesn't cut the cake anymore since it calls code in the xaml.cs. How would I create an ICommand equivalent?

• jquery plugins for truncating long text string by container width/height

  - by ShiVik

  Hello all As the title says, I want to truncate user-input text string based on the width and height of a designated container. My specification is to truncate the string, display some message like Read More at the end and when user clicks on it, the text slides down. UPDATE: Ah! Forgot one thing. It should handle multi-byte characters as well. Can somebody throw some light on what options do I have? jQuery plugins or some nifty jquery snippet? Thanks and Regards

• Is there anyone out there that codes like me?

  - by Jacob Relkin

  Hi, Some people have told me that my coding style is a lot different than theirs. I think I am somewhat neurotic when it comes to spacing and indenting though. Here's a snippet to show you what I mean: - ( void ) applicationDidFinishLaunching: ( UIApplication *) application { SomeObject *object = [ [ SomeObject alloc ] init ]; int x = 100 / 5; object.someInstanceVariable = ( ( 4 * x ) + rand() ); [ object someMethod ]; } Notice how I space out all of my brackets/parentheses, start curly braces on the same line, "my code has room to breathe", so to speak. So my questions are a) is this normal and b) What's your coding style?

• How do I ignore the UTF-8 Byte Order Marker in String comparisons?

  - by Skrud

  I'm having a problem comparing strings in a Unit Test in C# 4.0 using Visual Studio 2010. This same test case works properly in Visual Studio 2008 (with C# 3.5). Here's the relevant code snippet: byte[] rawData = GetData(); string data = Encoding.UTF8.GetString(rawData); Assert.AreEqual("Constant", data, false, CultureInfo.InvariantCulture); While debugging this test, the data string appears to the naked eye to contain exactly the same string as the literal. When I called data.ToCharArray(), I noticed that the first byte of the string data is the value 65279 which is the UTF-8 Byte Order Marker. What I don't understand is why Encoding.UTF8.GetString() keeps this byte around. How do I get Encoding.UTF8.GetString() to not put the Byte Order Marker in the resulting string?

• How would you write a program to find the shortest pangram in a list of words?

  - by jonathanasdf

  Given a list of words which contains the letters a-z at least once, how would you write a program to find the shortest pangram counted by number of characters (not counting spaces) as a combination of the words? Since I am not sure whether short answers exist, this is not code golf, but rather just a discussion of how you would approach this. However, if you think you can manage to write a short program that would do this, then go ahead, and this might turn into code golf :)

• Javascript form validation/sanitizing do i need regex here ?

  - by user318144

  I have a single form input that is for checking domains. Sometimes people type in www. before the domain or .com after the domain name. The service that i use to check availability automatically checks for all top level domains so when people add the .com at the end it becomes redundant. For example the string submitted is domainname.com.com which is clearly invalid. I understand you can do this on the server side but due to some rather weird circumstance i must use javascript for this. So is regex the solution here ? If so is there some kind of regex generator i can use for this or can someone point me in the right direction with a code snippet perhaps ? Appreciate any help thanks!
