• In php, Prepare string and create XML/RSS Feed

  - by Bill

  I want to create my own RSS/XML feed. I fetch data from the database to display, but keep getting invalid character errors. If the string has an ampersand or other strange characters in it, the XML will be invalid. I tried using urlencode and htmlentities, but these don't capture all possible characters which need to be escaped. Does anyone know of a PHP function which will prepare a string for XML output?

  - by Russell Giddings

  I frequently see lambda expression parameters abbreviated to one character. For example... var stringList = new List<string>{ "one", "two", "three" }; stringList.Where(x => x.Length < 4); Is it acceptable to use x as the parameter name here or should a more descriptive name be used?

• Web-serving a file : Firefix truncates name

  - by interstar

  I'm serving a file from Lighttpd whose name contains space-characters. I'm using mimetype "application/octet-stream" When I download this in Chrome, it works perfectly. But when I download in Firefox, the filename is truncated at the first space. Is this to do with the mimetype? With some other lightty config? Or maybe something to do with the kind of space-character I'm using?

• regular expression for string in c

  - by darkie15

  Hi All, I am working writing a regular expression used to validate string in C. Here is to what I have gone so far '^"[A-Za-z0-9]*[\t\n]*"$' for rules - A string should begin with double quotes - May not contain a newline character However, I am not able to capture the rule for allowing '\' or '"' in a string if preceded with '\'. Here is what I tried: '^"[A-Za-z0-9]*[\t\n]*[\\\|\\"]?"$' But this doesn't seem to work. What might be wrong with the regular expression here? Regards, darkie15

• Eclipse: view a document using custom spacing, save using the file's spacing

  - by Steven Sproat

  I have a silly use case for eclipse: At work, they use 2 spaces for a tab character. Indentation looks really squashed and I'm finding it obstructs readability. Now, I can't set Eclipse to use 4 spaces for a tab as it'll edit any files I change, and obviously don't want to violate the coding standards. So, can I have a custom view onto my document, with saving maintaining the original spacing? Cheers

• Remove Trailing Slash From Batch File Input

  I have a batch file that I want to improve. Instead of requiring a user to provide a folder path without a trailing slash, is there an easy way for me to just remove the last character from the path if there is a slash on the end? :START @echo What folder do you want to process? (Provide a path without a closing backslash) set /p datapath= ::Is string empty? IF X%datapath% == X GOTO:START ::Does string have a trailing slash? IF %datapath:~-1%==\ GOTO:START

• Why does Java's hashCode() in String use 31 as a multiplier?

  - by jacobko

  In Java, the hash code for a String object is computed as s[0]*31^(n-1) + s[1]*31^(n-2) + ... + s[n-1] using int arithmetic, where s[i] is the ith character of the string, n is the length of the string, and ^ indicates exponentiation. Why is 31 used as a multiplier? I understand that the multiplier should be a relatively large prime number. So why not 29, or 37, or even 97?

• Efective way to avoid integer overflow when multiplying?

  - by Jonathan

  Hi, I'm working on a hash function which gets a string as input. Right now I'm doing a loop and inside the hash (an int variable) is being multiplied by a value and then the ASCII code for the current character is added to the mix. hash = hash * seed + string[i] But sometimes, if the string is big enough there is an integer overflow there, what can I do to avoid it while maintaining the same hash structure? Maybe a bit operation included inside the loop?
