36,130,431 | 0 | <p>There is a very minor difference (effectively negligible, we're talking micro-optimization here), since the string should be stored in a local variable which takes that extra bit of memory on the stack frame of the corresponding method. Whereas the constants are actually stored in the constant pool and shared. With the likely optimizations of the JVM based on the number of invocations, it won't make a difference.</p> <p>Note that the bytecode would be the same if the variables were <code>final</code> or effectively <code>final</code> (assigned only once), since in this case they are treated as constants.</p> |
1,523,119 | 0 | <p>I am personally using Orbited, both because I am already using Twisted and because it seems mature. Twisted has a nice long history with many users, especially in comparison to Diesel and Tornado. Orbited is indeed built on Twisted.</p> <p>There is a good blog entry covering an <a href="http://cometdaily.com/2008/10/10/scalable-real-time-web-architecture-part-2-a-live-graph-with-orbited-morbidq-and-jsio/" rel="nofollow noreferrer">end-to-end orbit solution here</a>. It sends data from a python script to a STOMP server (MorbidQ) to Orbited to Javascript - rendering that data as a graph.</p> <p>Tornado seems pretty new to the scene, I couldn't find twisted-comet and I hadn't heard of diesel. I particularly like the way that Orbited can forward any sort of tcp/ip but makes it easy to hook javascript clients in with a message passing STOMP backend.</p> |

27,407,267 | 0 | New to JavaScript - Need help creating multiple objects with data from a form <p>I just started learning JavaScript and have been stuck on an assignment for about a week now, I've tried several solutions but every time I add something I break something else. The assignment is to create a form (which I have completed). The form is to be used to enter data for a new favorite item, when each item is entered it should be displayed on the page and in the console log, as additional items are entered they are added to the list and all items are displayed - </p> <p>Ex - Favorites are: URL:<a href="http://oriellyschool.com" rel="nofollow">http://oriellyschool.com</a>, title: O'Reilly School, comment: help, tags: school, learning, URL: <a href="http://google.com" rel="nofollow">http://google.com</a>, title: Google, comment: Use google to find info on JavaScript, tags: search, finding info faves:html:133</p> <p>The specific instructions are to use objects for both all favorites and each new favorite item. The functionality to display the favorites (in console and on page) should be included in the methods for the objects.</p> <p>I am able to get the data from the form into a function and had the function to create the favorites working yesterday, not sure what happened this morning.</p> <p>If someone could please take a look at this and tell me if I am at least heading in the right direction I would appreciate it.

The loop goes through each company in the array, passing the bonus to awk as a variable (note that I'm doing this using <code>-v</code> rather than using string concatenation). The loop goes from 1 to 12, adding the bonus for months 1, 5 and 9, or 5 otherwise. The name of the company (the key of the shell array) is used for the output file.</p> |
2,646,694 | 0 | Running job in the background from Perl WITHOUT waiting for return <h3>The Disclaimer</h3> <p>First of all, I know this question (or close variations) have been asked a thousand times. I really spent a few hours looking in the obvious and the not-so-obvious places, but there may be something small I'm missing.</p> <h3>The Context</h3> <p>Let me define the problem more clearly: I'm writing a newsletter app in which I want the actual sending process to be async. As in, user clicks "send", request returns immediately and then they can check the progress in a specific page (via AJAX, for example). It's written in your traditional LAMP stack.</p> <p>In the particular host I'm using, PHP's exec() and system() are disabled for security reasons, but Perl's system functions (exec, system and backticks) aren't. So my <del>workaround</del> solution was to create a "trigger" script in Perl that calls the actual sender via the PHP CLI, and redirects to the progress page.</p> <h3>Where I'm Stuck</h3> <p>The very line the calls the sender is, as of now:</p> <pre><code>system("php -q sender.php &"); </code></pre> <p>Problem being, it's not returning immediately, but waiting for the script to finish. I want it to run in the background and have the system call itself return right away. I also tried running a similar script in my Linux terminal, and in fact the prompt doesn't show until after the script has finished, even though my test output doesn't run, indicating it's really running in the background.</p> <h3>What I already tried</h3> <ul> <li>Perl's exec() function - same result of system().</li> <li>Changing the command to: "php -q sender.php | at now"), hoping that the "at" daemon would return and that the PHP process itself wouldn't be attached to Perl.</li> <li>Executing the command 'indirectly': "/bin/sh -c 'php -q sender.php &'" - still waits until sender.php is finished sending.</li> <li>fork()'ing the process and executing the system call in the child (hopefully detached process) - same result as above</li> </ul> <h3>My test environment</h3> <p>Just to be sure that I'm not missing anything obvious, I created a sleeper.php script which just sleeps five seconds before exiting. And a test.cgi script that is like this, verbatim:</p> <pre><code>#!/usr/local/bin/perl system("php sleeper.php &"); print "Content-type: text/html\n\ndone"; </code></pre> <h3>What should I try now?</h3> |

Only the last backslash on any physical source line shall be eligible for being part of such a splice. If, as a result, a character sequence that matches the syntax of a universal-character-name is produced, the behavior is undefined. A source file that is not empty and that does not end in a new-line character, or that ends in a new-line character immediately preceded by a backslash character before any such splicing takes place, shall be processed as if an additional new-line character were appended to the file.</p> </blockquote> <p>This is not clear regarding what happens if the last character in the file is a backslash. In such a case, presumably the result of adding the newline should not be a line splice but rather a backslash preprocessing-token (that will be diagnosed as an invalid token in phase 7), but that should be spelled out.</p> |

9,743,948 | 0 | <p>It's best if you can add a field that will not display on the application for the file unique_id in the table and then use that in a join to the data to populate the child tables. But sometimes you can't mess with the structure of a database especially if it is a COTS product. </p> <p>We have a sneaky trick for that. First load the data to a staging table (adding an identity if the file has no unique identifier on it's own) and an empty field for the parent_id. </p> <p>Next put the unique identifier into some other required field instead of its normal value (We use last_name but if you have one taht is the same datatype as the uniqueid that's better). Then you can join on the required field and the uniqueid from the staging table to update it to get the real parentid. Then update the field where you stored the temporary id with its real value (becasue now you can use teh real parent_id). Now you have the real parent_id in a table, the data flows for the child tables can join to that. This creates more work for the database, so only use it if you can't change the structure. </p> <p>Alternatively you can do all the inserting from a staging table using a stored proc and the execute SQL task rather than in a dataflow.</p> |

You could use a structure where each tag contains one of the <code>colj</code> arrays or you could return them through <code>keywords</code>.</p> <p>Then you can pass these arrays to another function/program in the following way:</p> <pre><code>PRO my_algorithm_wrapper,file_name,RESULTS=results ;; Get data from files columns = read_my_file(file_name) ;; Pass data to [algorithm] function results = my_algorithm(columns[*,0],columns[*,1],columns[*,2],columns[*,3]) ;; Return to user RETURN END </code></pre> <p>To call this from the command line (after making sure both routines are compiled), you would do something like the following:</p> <pre><code>IDL> my_algorithm_wrapper,file_name,RESULTS=results IDL> HELP,results ;; see what the function my_algorithm.pro returned </code></pre> <p>The above code should work with IDL 6.2.</p> <h1><strong>General Notes</strong></h1> <ol> <li>Try to avoid using uppercase letters in IDL routine names as it can cause issues when IDL searches for the routine during a call or compilation statement.</li> <li>You need to name the program/function in the line with the <code>PRO</code>/<code>FUNCTION</code> statement at the beginning of the file.

7,268,169 | 0 | Django Newbie Question: Activation View Being Called Twice ... 99% of the time - Invalid token error <p>Hi and thank you for looking at my question. When a user clicks activation link in their email, they get a token invalid error page. The user is activated and can use the site. After adding debugging I see that the activation view is being called twice. The first time it works as expected, but the second time the activation key no longer exists so there is an error. Just to make thing more complicated, it does work once in a very blue moon. Why would this happen? How can I prevent this from happening? Thanks!</p> |

30,477,337 | 0 | liquibase database build from scratch <p>When I run liquibase update from scratch, it takes a while as the process fires each changelog one by one. Sometimes my own database changes diverge enough that its easiest to rebuild the database if I want to start again for example.</p> <p>The rebuild would be quickest if I did it from a mysql dump of the result of liquibase at a certain point in the changelogs, and I ignored the changelogs from there previously. So I would delete everything in changelog master except my master build dump changelog, which would be the entire database, and I keep hold of the actual changelogs for version control reasons.</p> <p>Is there a proper/ordained/safe way to do this from liquibase?</p> |
19,169,115 | 0 | Phonegap: Keyboard changes window height in iOS 7 <p>In iOS 6 everything works fine. The keyboard opens and moves the input into view. When the keyboard closes everything goes back where it should.</p> <p>In iOS 7 the keyboard opens fine and the input remains in view. When the keyboard is closed the whole bottom half of the app is gone, though. I've tracked the issue down to the height of the window changing when the keyboard is opened, and not changing back when it's closed.</p> <p>Right before the keyboard is opened the window height is 568 according to $(window).height() and after it's opened and after it's closed it is 828. The height of the document also changes accordingly.</p> <p>I've attempted preventing the window from resizing with:</p> <pre><code>$(window).resize(function(e) { e.preventDefault(); e.stopPropagation(); window.resizeTo(320,480); return false; }); </code></pre> <p>I've also attempted to set the size back after the keyboard closes with no success.</p> <p>I'm using phonegap 2.7 and have KeyboardShrinksView set to true. </p> |
