  • what's the difference between php time and sql time

    - by Ying
    Can anyone tell me why the timestamp generated by the php time() function is so different from SQL datetime? If i do a date('Y-m-d', time()); in php, it gives me the time now, as it should. If I just take the time() portion and do: $now = time(); //then execute this statement 'SELECT * FROM `reservation` WHERE created_at < $now' I get nothing. But hey, so if the value of $now was 1273959833 and I queried 'SELECT * FROM `reservation` WHERE created_at < 127395983300000000' Then I see the records that ive created. I think one is tracked in microseconds vs the other is in seconds, but I cant find any documentation on this! What would be the right conversion between these two?? any help appreciated.

  • Can you boot/install/restore a MacBook Pro with a MacBook Air USB stick?

    - by zekel
    The new MacBook Airs don't have optical drives, so you can't install or restore the OS via DVD. They include a little USB stick for this purpose. I have a MacBook Pro and a MacBook Air. Does anyone know if it will work with my MacBook Pro? I'm thinking about removing my optical drive to put in another HD. The only sticky situation I might get into is if I need to do an install or restore on the road without an external DVD drive. (Good article on replacing optical drive with hard drive enclosure: remiel.info/post/1601242301/making-the-leap-to-ssd-on-a-macbook)

  • Picasa 3 - All 88 'people' folders are empty - can I restore the files?

    - by rogerbid
    My wife uses Picasa 3 on her laptop, and has a problem. She has no idea how it happened but somehow the left hand panel in the Picasa 3 window shows "People (88)" but listed below it are the 88 names each with "(0)" alongside. No thumbnails show up for any of the 'people'. I have looked through all the menus and can see nothing that seems relevant and a search on this website has been fruitless too. Can anyone please tell me how I can correct this situation? FYI I backed up the laptop to a portable hard drive a few days ago (using Windows Backup and Restore) and wonder if this can be used to restore the database.

  • Difference between abstract class and interface

    - by nectar
    A class implementing an interface has to implement all the methods of the interface, but if that class is implementing an abctract class is it necessary to implement all abstract methods? If not, can we create the object of that class which is implementing the Abstract class???

  • Difference in calling redefined functions in F# and Clojure

    - by Michiel Borkent
    In F#: > let f x = x + 2;; val f : int -> int > let g x = f x;; val g : int -> int > g 10;; val it : int = 12 > let f x = x + 3;; val f : int -> int > g 10;; val it : int = 12 In Clojure: (defn f [x] (+ x 2)) (defn g [x] (f x)) (g 10) ;; => 12 (defn f [x] (+ x 3)) (g 10) ;; => 13 Note that in Clojure the most recent version of f gets called in the last line. In F# however still the old version of f is called. Why is this?

  • Click behaviour - Difference in IE and FF ?!

    - by OlliD
    Hey folks, i just came to the conclusion that a project i am currently working on might have a "logical" error in functionality. Currently I'am using server technology with PHP/MySQL and JQuery. Within the page there's a normal link reference with tag <a href="contentpage?page=xxx">next step</a> The pain point now seems to be the given jquery click event on the same element. The intension was to save the (current) content of the page (- form elements) via another php script using the php session command. For any reason, IE can handle the click event of Jquery right before executing the standard html command, that reloads the current page again with the new page parameter. By using FF the behaviour is different. I assume, that FF first execute the html command and afterwards execute the javascript code which handles the click event. Therefore the resultset here is wrong respectivly empty. My question now is whether you made the same experience and how you handled / wordarrounded this problem. I'd be thankful fur any of your tips or further feedback. Maybe you also have a solution on how to rethink about the current architecture. Regards, Oliver

  • Difference between DirectCast() and CType() in VB.Net

    - by Chapso
    I am an experienced C/C++/C# programmer who has just gotten into VB.NET. I generally use CType (and CInt, CBool, CStr) for casts because it is less characters and was the first way of casting which I was exposed to, but I am aware of DirectCast and TryCast as well. Simply, are there any differences (effect of cast, performance, etc.) between DirectCast and CType? I understand the idea of TryCast.

  • What's the difference between /123 and /?123?

    - by BoltClock
    I've noticed that some sites (including http://jobs.stackoverflow.com) have query strings that look like this: http://somewebapp.example/?123 as compared to: http://somewebapp.example/123 or http://somewebapp.example/id/123 What are the reasons that developers choose to implement their web apps' URLs using the first example instead of the second and third examples? And as a bonus, how would one implement the first example in PHP, given that 123 is the primary key of some row in a database table? (I just need to know how to retrieve 123 from the URL; I already know how to query the database for a primary key of 123.)

  • Timer in java ,time difference problem

    - by javatechi
    I want to create a timer for my app. The sample code is shown below. When the method datetwo() is called the same time in milliseconds is shown as there in the main method. Please help me out with this import java.util.Date; import java.util.Timer; public class TimerChe { Timer timer; static Date date = new Date(); static Date date2 = new Date(); public static void timerMethod(){ new Thread() { public void run() { try { while (true) { sleep(10000); datetwo(); } } catch (InterruptedException ex) { } } }.start(); } public static void datetwo() { System.out.println ("OK, It's time to do something!") ; System.out.println("The Time is " + date2.getTime() + " milliseconds since 1970/01/01"); } public static void main(String args[]) throws Exception { System.out.println("The Time is " + date.getTime() + " milliseconds since 1970/01/01" ); System.out.println ("Schedule something to do in the mean time.") ; timerMethod(); } }

  • Can I automatically attach to the lifecycle of ANY server-enabled HTML tag?

    - by Deane
    If a "server-enabled" HTML tag is in a Web form, like this -- <p runat="server"/> -- is there any way for me to attach to its rendering? I assume once they have runat="server", they must have a lifecycle of some kind. I'd like to attach some code to the rendering of any HTML tag so enabled. So, whenever a template author puts runat="server" on a tag, I can catch the PreRender (or anything else) and execute some code. Possible?

  • Difference between var and Class class in object creation

    - by Divine
    Its a silly question, however shocked to see different behaviors. Learning a lot. Lets say I have two classes below Class A { public void Display() { } } Class B : A { public void Display() { } } Class C : B { public void Display() { } } Class Final { static void Main() { var c = new C(); // B c = new C(); //My doubt is, both of the above gives different results. May I know B c = new C() creates object of B or C? What I understood is, it creates object of B. Then why we say "new C()"? I agree with C c = new C(); But I thought, B b = new C(); creates object of B. Where we use this style? Only when utilizing runtime polymorphism? (Overriding methods)? } }

  • Strange difference between optimized/non optimized microsoft c++ code

    - by Anders Forsgren
    I have a c++ program with a method that looks something like this: int myMethod(int* arr1, int* arr2, int* index) { arr1--; arr2--; int val = arr1[*index]; int val2 = arr2[val]; doMoreThings(val); } With optimizations enabled (/O2) the first line where the first pointer is decremented is not executed. I assume the compiler believes that the arr1 array is not used since it thinks it can remove the decrement. Am I violating some convention in the above code? What could cause this behavior? It is a very old piece of f2c-translated code, the pointer decrement is due to the 1-based indexing of the original code.
