I am building a pure-Ruby WAV file read/write library, learning deeper Ruby functionality as I go. It currently works well with 16-bit audio, as I am able to use String.unpack('s*') to pull individual audio samples out into an array of signed integers. I am having trouble wrapping my mind around how to go about dealing with 24-bit audio,...
I have a list of websites in a string and I was doing a for loop to add "http" in the front if the first index is not "h" but when I return it, the list did not change. n is my list of websites h is "http" for p in n: if p[0]!="h": p= h+ p else: continue return n when i return the list, it returns my original...

If I have a array with objects: $a = array($objA, $objB); (each object has a __toString()-method) How can I cast all array elements to string so that array $a contains no more objects but their string representation? Is there a one-liner or do I have to manually loop through the array? ...

I'm having some trouble adding a mutable string (that has been changed with replaceOccurrencesOfString) to an array.

I have to replace all ocurrences of: 5.6xx and 5.5xx (where x is a 0-9 digit) on a textfile with 5.500, but only when the line that contains the match starts with a string (e.g. STARTSTRING). That means STARTSTRING 5.610 4.500 3.550 5.530 OTHERSTRING 5.600 5.500 5.500 5.600 should become STARTSTRING 5.500 4.500 3.550 5.500 OTHERSTRIN...
In a sh shell script. Given data in a text file: string1 string2 gibberish gibberish string3 gibberish string4 How could you use awk or sed to remove all lines between string2(inclusive) and string3(not including string 3)? to end up with: string1 string3 string4 ...
How can I print a non-null-terminated string using printf, assuming that I know the length of the string at runtime? ...
I'm currently working with a SPC that supports ANSI C, but uses its own flavour of the GNU compiler, which doesn't compile any variadic functions and things like itoa. So using sprintf & co. isn't an option for converting integers to strings. Can anyone guide me to a site where a robust, sprintf- free implementation of itoa is listed or ...
Hi all, I have a persistence ignorant domain model that uses abstract repositories to load domain objects. The concrete implementation of my repositories (the data access layer (DAL)) uses entity framework to fetch data from a sql server database. The database has length constraints on a lot of its varchar columns. Now imagine that I ...

What I need to do is compare two strings and mark the differences with begining/ending marks for changes. Example: this is string number one. this string is string number two. output would be this [is|string is] string number [one|two]. I've been trying to figure this out for some time now. And I found something I blieved would h...
I'm storing multiple numbers in a MySQL cell by using a delimiter (eg "1,5,10") and the TEXT datatype. How do I perform lookups like this? SELECT * FROM MyTable WHERE MultiVals CONTAINS "5" And lastly, is this the preferred approach to store such values? I'm using this like a linker table, to link certain rows to multiple other rows ...
Hi, I have a control that will return some html to me as a string. Before putting that on screen, I'd like to be able to tell if it'll just show as empty. For example the control might return <p><br /></p>, which when I test using C# for string.Emtpy obviously it's not - but nothing gets displayed on screen. Is there a regex function ...
I get strings in different encodings (ID3 tags). I use e.g. new String( bytes, "UTF-16LE" ) to decode them. On my device (Motorola Milestone) and in the emulator, this works fine. But some users complained they get results like "T i t l e n a m e". I've tried the Sun codepage names instead (e.g. "UnicodeBigUnmarked"), with the same res...
I used a variable with a lot of data in it, say String data. I wanted to use a small part of this string in the following way: this.smallpart = data.substring(12,18); After some hours of debugging (with a memory visualizer) I found out that the objects field smallpart remembered all the data from data, although it only contained the s...
I'm creating a key for a dictionary which is a structure of two strings. When I test this method in a console app, it works, but I'm not sure if the only reason it works is because the strings are being interned and therefore have the same references. Foo foo1 = new Foo(); Foo foo2 = new Foo(); foo1.Key1 = "abc"; foo2.Key1 = "abc"; foo1...
