I'm trying to build a script to go through my original, high-res photos and replace the old, low-res ones I uploaded to Flickr before I had a pro account. For many of them I can just use Exif info such as date taken to determine a match. But some are really old, and either the original file didn't have Exif info, or it got clobbered by ...

Any performance comparisons with other Java web frameworks? Edit:Almost similar to http://stackoverflow.com/questions/1597086/any-experience-with-play-java-web-development-framework, the re...

Hi Guys, Ok, the problem is that when my app runs on the simulator it seems to work fine. On the device, however it does not update all the labels. I think the error is somewhere here: - (IBAction)buttonclick1 { self.startDate = [NSDate date]; double value = [self Level]; double value2 = [self Level2]; if ((va...
I'm trying to write a Compare method to compare properties in some POCOs using Reflection to ensure that they've been persisted to the database correctly. For example, let's say I have this POCO: public class NoahsArk { public string Owner { get; set; } public ICollection<Animal> Animals { get; set; } } What I want to do is th...
Is there any notion of pointer quality in Haskell? == requires things to be deriving Eq, and I have something which contains a (Value -> IO Value), and neither -> nor IO derive Eq. EDIT: I'm creating an interpreter for another language which does have pointer equality, so I'm trying to model this behavior while still being able to use H...
Does anyone know of a table or chart that compares the features of SQL Server, SQLite, and MySQL (maybe Oracle too) ? An example of what I'm looking for exists at DEVX, but doesn't include SQL Sever or SQLite ...
I trying to write a programm for file compare. For example: file1 1 2 3 4 5 file2 1 2 @ 3 4 5 If I do it line by line, I get: 1 == 1; 2 == 2; 3 != @; 4 != 3; 5 != 4; != 5; But, the truth is that the only difference between the files is @. I want get something like this: 1 == 1; 2 == 2; != @; 3 == 3; 4 == 4; 5 == 5; Whic...
Say I have the following hashes: hash_x = { :a => 1, :b => 2 } hash_y = { :b => 2, :c => 3 } I need a chunk of logic that compares the two for equality only taking into consideration intersecting keys. In this example the 'b' key is the only commonality between the two hashes and it's value is set to '2' in both so by that ...
I was looking at the implementation of compare(double, double) in the Java standard library (6). It reads: public static int compare(double d1, double d2) { if (d1 < d2) return -1; // Neither val is NaN, thisVal is smaller if (d1 > d2) return 1; // Neither val is NaN, thisVal is larger long thisBits =...
I am trying to find out which is the proper way to fetch data from my database. Either way works, but what's the difference; an in-depth explanation? $sql = mysql_query("SELECT * FROM _$setprofile"); while($row = mysql_fetch_array($sql)) { $username = $row['user']; $password = $row['pass']; echo "$username:$password"; } ve...
I'm going to rebuilt an existing moderate-scale web-app to be used for a supply-chain-management web-solution.
