• What the difference between zend framework and Wordpress as framework ?

  - by justjoe

  i only know wordpress and start to seek another alternative framework, zend. i heard hearsay that zend's better from others framework. if you're "a serous coder", or try to act like one, you need to use it on building your web app. some said zend is better. But it's subjective. It's fast ans secure. But nobody tell me the reason or at leas compare it with with wordpress. ultimate question : Do zend have theme or plugin just like wordpress ? any hint will be helpful

• Does it make a difference in performance if I use self.fooBar instead of fooBar?

  - by mystify

  Note: I know exactly what a property is. This question is about performance. Using self.fooBar for READ access seems a waste of time for me. Unnecessary Objective-C messaging is going on. The getters typically simply pass along the ivar, so as long as it's pretty sure there will be no reasonable getter method written, I think it's perfectly fine to bypass this heavy guy. Objective-C messaging is about 20 times slower than direct calls. So if there is some high-performance-high-frequency code with hundreds of properties in use, maybe it does help a lot to avoid unnessessary objective-c messaging? Or am I wasting my time thinking about this?

• What's the difference between ISO 8601 and RFC 3339 Date Formats?

  - by Brig Lamoreaux

  ISO 8601 and RFC 3339 seem to be two formats that are common the web. Should I use one over the other? Is one just an extension? Do I really need to care that bad?

• What is the difference between login and credential in SQL server 2008?

  - by ebeworld

  I am a bit confused SQL server windows login and credential. On books online, it says that credential can access resources beyond sql server, but as far as i see windows login might be able to do that that since it is mapped to a windows user. Am i missing something else? Thanks, in advance.

• Difference between these two ways of localizing a string in an aspx/ascx file?

  - by Brandon

  When I started localizing a website the first time, I just did the localization like this: <%= Resources.ResourceFile.ResourceName %> and it seems to work perfectly fine. However, the ReSharper 5.0 Beta does it like this: <asp:Localize Text="<%$ Resources: ResourceFile, ResourceName %>" runat="server"> Value </asp:Localize> Does it matter which way it gets done? If it doesn't matter, is there any way to make ReSharper do it the way I'm doing it? I kind of prefer it this way since it is less text in the aspx/ascx files.

• What is the performance difference between blocks and callbacks?

  - by Don

  One of the things that block objects, introduced in Snow Leopard, are good for is situations that would previously have been handled with callbacks. The syntax is much cleaner for passing context around. However, I haven't seen any information on the performance implications of using blocks in this manner. What, if any, performance pitfalls should I look out for when using blocks, particularly as a replacement for a C-style callback?

• When does the difference between a string and a number matter in Perl 5?

  - by Chas. Owens

  If a string in Perl 5 passes looks_like_number, it might as well be a number. For instance, my $s = "10" + 5; results in $s being assigned 15. Are there any cases where a string does not behave like it's numeric equivalent would have?

• In SQL / MySQL, what is the difference between "On" and "Where" in a join statement?

  - by Jian Lin

  The following statements give the same result (one is using "on", and the other using "where"): mysql> select * from gifts INNER JOIN sentGifts on gifts.giftID = sentGifts.giftID; mysql> select * from gifts INNER JOIN sentGifts where gifts.giftID = sentGifts.giftID; I can only see in a case of a Left Outer Join finding the "unmatched" cases: (to find out the gifts that were never sent by anybody) mysql> select name from gifts LEFT OUTER JOIN sentgifts on gifts.giftID = sentgifts.giftID where sentgifts.giftID IS NULL; In this case, it is first using "on", and then "where". Does the "on" first do the matching, and then "where" does the "secondary" filtering? Or is there a more general rule of using "on" versus "where"? Thanks.

• What is the difference between a private and public funtion?

  - by Kyle

  I am a new programmer, and I started in C and am now starting to enjoy JavaScript and a tiny bit of PHP more. Lately I've heard the terms 'private' and 'public' functions a lot. Could anybody give an explanation of the both and how they are of use to a programmer? And I'm probably totally wrong here... but is a (function(){}) in javascript a private function?

• On Solaris, what is the difference between cut and gcut?

  - by Chris J

  I recently came across this crazy script bug on one of my Solaris machines. I found that cut on Solaris skips lines from the files that it processes (or at least very large ones - 800 MB in my case). > cut -f 1 test.tsv | wc -l 457030 > gcut -f 1 test.tsv | wc -l 840571 > cut -f 1 test.tsv > temp_cut_1.txt > gcut -f 1 test.tsv > temp_gcut_1.txt > diff temp_cut_1.txt temp_gcut_1.txt | grep '[<]' | wc -l 0 My question is what the hell is going on with Solaris cut? My solution is updating my scripts to use gcut but... what the hell?

• Can we find out the difference between 2 RGb colors to find out a 3rd color?

  - by AK

  2 colors are mixed together. If i have the RGB for the resultant color and RGB for one of the colors mixed, then somehow i could calculate the 2nd color? I will try to explain visually what i am trying to say. Here is a flickr link http://www.flickr.com/photos/48150615@N08/4407414157 I know that the circle in the middle has an opacity of 20% Is there any way to know the color value of the circle so that i can deduct that to get the same color value as the background color.

• What are MVP and MVC and what is the difference?

  - by Wolfbyte

  When looking beyond the RAD (drag-drop and configure) way of building User Interfaces that many tools encourage you are likely to come across 2 design patterns called Model-View-Controller and Model-View-Presenter. My question has two parts to it: What issues do these patterns address? How are they similar? How are they different?

• What's the difference between single and double quotes in Objective-C?

  - by Alex Mcp

  I'm working through a book exercise to generate some random serial number, and here's my function: NSString *randomSerialNumber = [NSString stringWithFormat:@"%c%c%c%c%c", '0' + random() % 10, 'A' + random() % 26, '0' + random() % 10, 'A' + random() % 26, '0' + random() % 10]; This works and has an output like: 2J6X7. But before, the 0s and As I had wrapped in double quotes, and an example output was 11764iÒ˜. What did I do wrong my first time around, and why did using single quotes fix it?

• What is the difference between a site and an app in Django?

  - by larf311

  I know a site can have many apps but all the examples I see have the site called "mysite". I figured the site would be the name of your site, like StackOverflow for example. Would you do that and then have apps like "authentication", "questions", and "search"? Or would you really just have a site called mysite with one app called StackOverflow?

• MySQL - Calculate the net time difference between two date-times while excluding breaks?

  - by John M

  In a MySQL query I am using the timediff/time_to_sec functions to calculate the total minutes between two date-times. For example: 2010-03-23 10:00:00 - 2010-03-23 08:00:00 = 120 minutes What I would like to do is exclude any breaks that occur during the selected time range. For example: 2010-03-23 10:00:00 - 2010-03-23 08:00:00 - (break 08:55:00 to 09:10:00) = 105 minutes Is there a good method to do this without resorting to a long list of nested IF statements?
