• What's the most effective path to top level development?

  - by Glycerine

  I got a questions asked from one of my delegates the other day, "how did you get to where you are in programming?" I'm now at a java application realm - and I'm just about OK at it. the path that brought me there: BASIC VB6 PHP javascript actionscript java/objective-C I still live in the web development but I now prefer java - I see this as a good flow but I was wondering how you guys got to where you are and the best path to take? Edit: reword I guess I've asked the question wrong - I was wondering how to progress to a top level application from starting off in development. Where good paradyms connect languages. I won't have considered C++ as my first language see.

• CakePHP: Accessing the controller or model from a view helper

  - by tombazza

  I have a view helper that manages generating thumbnails for images. The images are stored using a unique ID and then linked to a file resource in the database. I am trying to find out if it is possible for the view helper that generates these images to access the model or controller directly, as it is not possible to load the image data at any other point in the controller work flow. I know this is a bit of a hack really, but it is easier than trying to rebuild the entire data management stack above the view.

• How messages flows between computers connected with Internet or LAN ?

  - by Praveen

  Hi All, I have been doing Windows programming in .Net since last two years. Now I am shifting to web programming so I just stuck in understanding the fundamentals of web programming, after googling I came to StackOverflow to learn from all of you great guys. My confusion is about how messages flow between systems in distributed enviornment ? I mean suppose I want to send a message "Hello" to a system connected to LAN or Internet, then what will be the steps taken to send the message. Second thing is suppose my system is "A" and I wana send message to system "B" which is connected via a wire, so how the message flows on wire and how system "B" reads it from the wire ? Please someone explain me in a layman terms. Thank you all in advance.

• Design guidelines for cache mechanism

  - by Delashmate

  Hi All, I got assignment to write design for cache mechanism (this is work assignment, not homework), This is my first time writing a design document, Our program display images for doctors, and we want to reduce the parsing time of the images So we want to save the parsed data in advance (in files or inside database) Currently I have several design key ideas: Handle locks - each shared data structure should be handled, also files Test - add test to verify the data from the cache is equal to the data from the files To decouple the connection to the database- not to call directly to the database Cleanup mechanisem- to delete old files if the cahce directory exceed configurable threshold Support config file Support performance tool in the feature I will also add class diagram, data flow charts, and workflow What do you think I should add to the key ideas? Do you know good link to atricales about design? Thanks in advance, Dan

• What's the best way to debug AJAX to PHP calls?

  - by Jascha

  I'm having a miserable time debugging one small function on my new project. Essentially I'm having a user log out via an AJAX call to my log out script on my server called "userfFunctions.php" I'm using AJAX so that I don't have the headache of writing more regex to match my mod_rewrites. Anyway, every so often, it seems as though my Post data just flat out dies and since the PHP is running behind the scenes, I feel like I have no way of finding out where the data flow is being disrupted. BTW This function works 19 hrs of the day. Here is the javascript function: function logOut(){ var data = new Object; data.log_out = true; $.ajax({ type: 'POST', url: 'http://www.mydomain.com/User_Validator', //<-- redirects to userFunctions.php data: data, success: function(data) { alert(data); // <-- a response is triggered but with no response data! } }); } the php side: if(isset($_POST['log_out'])){ echo 'alert this!'; } here is my awesome response:

• Flash: How to get a list to be processed synchronous instead of asynchronous?

  - by Quandary

  Question: In Flash I have the below function. Now the problem is SaveFurniture, SavePolygons and SaveComments all save to the same XML file. Now SaveFurniture sends JSON encoded data to a ashx handler, which saves it in the xml on the server. The problem is, because flash sends the data asynchronous, the polygons get sent to the polygonsave ashx handler, but before saving of the furniture has completed, thus access error, write process already in progress... // cSaveData.SaveData(); public static function SaveData():void { trace("cSaveData.SaveData"); //NotifyASPXofNewScale(cGlobals.nPlanScale); SaveFurniture(); SavePolygons(); SaveComments(); } What's the best way to process this list, ONE AFTER ANOTHER ? Making a callback in all of them does make the program flow structure very confusing...

• How to alter my mac os $PATH variable so that I can run the latest php version? [closed]

  - by skiabox

  Possible Duplicate: What are PATH and other environment variables, and how can I set or use them? I've just followed this article (http://mac.tutsplus.com/tutorials/server/upgrading-the-native-php-installation-on-os-x-mountain-lion/) to update my php installation using HomeBrew. The latest php version is indeed installed in /usr/local/bin The problem is that my $PATH variable is the following (doing an echo $PATH reveals it) : /usr/local/mysql/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin ...so the old version of php (that comes with mountain lion) always run first Any ideas on how to solve this? Thank you.

• Are there any XML Editors with FTP and file-tree browsing combined?

  - by JW

  Are there any (free preferably) XML Editors combined with FTP and file-tree browsing Project wide find+Replace I.e A bit like what Dreamweaver MX is but with fancier XML capabilities /XSLT /XSD Perhaps even DW does this...im still on an older version. I'd like to keep a smooth flow between find-edit-view-upload any ideas? Background: I have converted most of the html files of my legacy site into XML (which match the directory structure of my 'public docs' folder). Part of a step towards turning it into completely dynamic data via MVC /Front Controller Pattern.

• Is this a reasonable way to handle getters/setters in a PHP class?

  - by Mark Biek

  I'm going to try something with the format of this question and I'm very open to suggestions about a better way to handle it. I didn't want to just dump a bunch of code in the question so I've posted the code for the class on refactormycode. base-class-for-easy-class-property-handling My thought was that people can either post code snippets here or make changes on refactormycode and post links back to their refactorings. I'll make upvotes and accept an answer (assuming there's a clear "winner") based on that. At any rate, on to the class itself: I see a lot of debate about getter/setter class methods and is it better to just access simple property variables directly or should every class have explicit get/set methods defined, blah blah blah. I like the idea of having explicit methods in case you have to add more logic later. Then you don't have to modify any code that uses the class. However I hate having a million functions that look like this: public function getFirstName() { return $this->firstName; } public function setFirstName($firstName) { return $this->firstName; } Now I'm sure I'm not the first person to do this (I'm hoping that there's a better way of doing it that someone can suggest to me). Basically, the PropertyHandler class has a __call magic method. Any methods that come through __call that start with "get" or "set" are then routed to functions that set or retrieve values into an associative array. The key into the array is the name of the calling method after get or set. So, if the method coming into __call is "getFirstName", the array key is "FirstName". I liked using __call because it will automatically take care of the case where the subclass already has a "getFirstName" method defined. My impression (and I may be wrong) is that the __get & __set magic methods don't do that. So here's an example of how it would work: class PropTest extends PropertyHandler { public function __construct() { parent::__construct(); } } $props = new PropTest(); $props->setFirstName("Mark"); echo $props->getFirstName(); Notice that PropTest doesn't actually have "setFirstName" or "getFirstName" methods and neither does PropertyHandler. All that's doing is manipulating array values. The other case would be where your subclass is already extending something else. Since you can't have true multiple inheritance in PHP, you can make your subclass have a PropertyHandler instance as a private variable. You have to add one more function but then things behave in exactly the same way. class PropTest2 { private $props; public function __construct() { $this->props = new PropertyHandler(); } public function __call($method, $arguments) { return $this->props->__call($method, $arguments); } } $props2 = new PropTest2(); $props2->setFirstName('Mark'); echo $props2->getFirstName(); Notice how the subclass has a __call method that just passes everything along to the PropertyHandler __call method. Another good argument against handling getters and setters this way is that it makes it really hard to document. In fact, it's basically impossible to use any sort of document generation tool since the explicit methods to be don't documented don't exist. I've pretty much abandoned this approach for now. It was an interesting learning exercise but I think it sacrifices too much clarity.

• How to restrict access to the files outside document root in apache?

  - by Bakhtiyor

  I have virtual hosts in /var/www/site1 and /var/www/site2 folders. I want to restrict access to the files outside document root in apache virtual host, i.e. site1 could not access files of site2. Right now this scripts in /var/www/site1 works fine, which is not good: $filename = "/var/www/site2/somefile"; $handle = fopen($filename, "r"); $contents = fread($handle, filesize($filename)); echo $contents; How to solve this problem please? Thank you very much!

• Run preseed commands as specific user / switching users

  - by pduersteler

  Beside the usual setup where I create a normal user foo, I want to run a few d-i preseed/late_command commands as that foo user. My initial thought was to simply call those commands with sudo, e.g: d-i preseed/late_command in-target echo "<pwd>" | sudo -Si <command>. This works for some sort of commands. However the problem is that some of the commands load up shell scripts which require to not be run with sudo. Issuing a su -c "<command>" would be an alternative, but su does not offer the possibility to read the password from stdin. Is it safe to jump around between the users using su (And if yes, how do I provide the stdin? and does it work or just result in a su: must be run from a terminal) or would this cause issues?

• iPad --- managedObject problem when [self.tableViewSection reloadData]

  - by user345777

  Hi , I am creating a news aggregator application that fetches a xml feed every 4 minutes. After the xml is loaded, I clear everything by deleting all the objects in the database, then save the new objects back into the database. I then call [self.tableViewSection reloadData]; to reload the tableView. Thats when I get a problem. As soon as the code gets to a section where i access the new [[managedObject valueForKey:@"event_text"] description] content it fails with a : * Terminating app due to uncaught exception 'NSObjectInaccessibleException', reason: 'CoreData could not fulfill a fault for '0x4b3f6a0 '' Now from the flow I described on top, it seems odd to me that the tableView is populated properly the next time i launch the application, with the "new" data I fetched in the previous session. So its not that data thats corrupt , but seems to me something goes wrong when I refetch the managedObject after saving new data. Also keep in mind thats this app runs fine on the iPhone, its the iPad thats is giving me this problem.

• Mac OS X keeps "old" environment variable around

  - by Xymak1y

  So far I had /Applications/play-1.2.5/ added to my $PATH variable. Now I'm working with 2.2.1, which I installed in /Applications/play-2.2.1 and changed in ~/.bash_profile (which is getting sourced at startup). However, when printing $PATH, 1.2.5 is somehow still around: mbp:~ user$ echo $PATH /usr/local/share/npm/bin:/Applications/play-2.2.1:/usr/local/heroku/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/Applications/play-1.2.5:/Applications/XAMPP/xamppfiles/bin/:/opt/X11/bin As far as I now, I only entered $PATH variables in .bash_profile, which looks like this: mbp:~ user$ cat .bash_profile source ~/.git-completion.bash ### Added by the Heroku Toolbelt export PATH="/usr/local/heroku/bin:$PATH" ### Play Framework export PATH="/Applications/play-2.2.1:$PATH" export PATH="/usr/local/share/npm/bin:$PATH" I'm also not sure where the XAMPP extension to the variable comes from. Can I see somewhere which other files are being sourced on startup?

• Different behaviour of script locally and over ssh

  - by neorg

  I have a script on a server-A Script-A #!/bin/bash -l echo "script-A.sh" | change-environment.sh When I ssh onto server-A and execute it, it works fine. However, when I ssh user@server-A ./script-A.sh Script-A executes, but throws an undefined variable error in change-environment.sh. change-environment.sh runs in the c shell(I have no control over the script so the method I have used is about the only way I can use it), but everything else is in bash. Had found a similar question at I can run a script locally, but cannot do "ssh HOSTNAME /path/to/script.sh". However, there was no solution to the issue and it was a year old.

• How to deal with a coworker who keeps asking instead of searching herself?

  - by mafutrct

  I'm lucky enough to share a room with 3 other people at work. One of them, a senior programmer who's very talkative in general, tends to ask me various questions throughout the day. While some of them are surely ' legitimate', many questions could have been answered by putting in just slightly more search effort on their part. I really don't mind be asked stuff, and I can also cope with beginner questions, but this is seriously interrupting my flow. I clearly remember Joel talking about how private offices increase productivity because they prevent too easy questions from being asked. How should I deal with this situation? Getting a private office is out of the question, sadly. It's difficult to approach him directly, and he blissfully ignored the slight hints I tried to give.

• Put Raphael (SVG) canvas behind other divisions to make them clickable?

  - by Kerry

  I am using Raphael to create lines between divisions in an organization chart (or flow chart), but I need to be able to actually click on the divisions and content behind it. If I could make the canvas be behind the other elements, kind of like a background image, that would be idea. Is this possible? UPDATE: I found a solution. Raphael makes an SVG canvas that is absolutely positioned in my case. Absolute positions act as layers, and so to be on top of that layer, my content had to be absolutely positioned as well. If someone else has a better solution, I would be happy to hear it, though this is working fine.

• OOMK kills mysql and apache when there is still a lot[?] of mem

  - by Flyer

  let me first say that I'm pretty new ti *nix systems and even more to server management. Anyway, I've got a little problem. I got VPS with 1gb mem, system is debian 6. I have few sites running on it, though some load can only be caused by one of them. Recently, OOMK started to kill mysql, causing wp and phpbb giving error that it can't connect to mysql server. Error itself is not good, especially if it happens at night and site becomes unavailable until I wake up and restart mysql. I have probably bad line in my cron which can be cause of it all (again, I'm new to it) */20 * * * * sync; echo 3 > /proc/sys/vm/drop_caches Well, if you need any information, let me know, since I don't really know which information can be useful here. Also, I'd like to know if it's not too bad to have above cron task.

• Is there a way to alter Zend Studio PhpDoc preferences?

  - by Tower

  Hi, I'm trying out Zend Studio trial and I have a few things on my mind related to PhpDoc. If I have the following code: public function sum($a, $b) { echo $a + $b; } and then I start typing /** in the front of the function and press Enter, Zend Studio automatically makes the following text: /** * [cursor] * @param unknown_type $a * @param unknown_type $b */ However, I want to customize this so that it also includes @return void automatically since there's no return inside the function. Is there a way to do this? And what about things like @access? It's obviously "public". Another thing I want is that when I create a new file and I use the code templates with ${user}, it will use my Windows account, but I want it to use something else - is there a way to specify this "user"?

• How do you plan for starting a new web system?

  - by Kerry

  I've been creating more and more systems recently and I find more and more planning and preparation I do before starting the project. I determine what libraries or frameworks I will be using, what languages, the basic architecture of how the site will flow, etc. I've also heard of other design processes such as hanging styrofoam balls to show where classes are and how they relate, which is a process I've never heard of nor do I know how it works. Is there any software that helps with this process? Are there any guidelines or steps or do you have a recommended set of steps or guidelines that you follow when designing a new project?

• What are the different file permission codes and what do they mean?

  - by zeckdude

  I am working with a file upload script. I am currently uploading a file and then trying to echo out an anchor linking to that file, but since I used mkdir() with 0700 permissions to upload the file, it won't allow me access to view the file. I am pretty sure the problem I am experiencing is because of the file permission code I used. The problem is I just don't know what all the different file permission codes are and what they mean. Can somebody please list out all the different file permissions and what they each do?

• [iOS] How to catch cancallation of UIScrollView or others?

  - by kyu

  Sometimes, interruptions such as phone call occur and disturb a regular behavior of an app in iPhone or iPad. For example, I created one UIScrollView instance and implemented UIScrollView delegate methods: scrollViewWillBeginDragging and scrollViewDidEndDragging(and scrollViewDidEndDecelerating). A scrollViewWillBeginDragging method deactivated all custom buttons in my app. Then scrollViewDidEndDragging and scrollViewDidEndDecelerating methods activated these custom buttons. That is, while the user scrolled, all custom buttons became deactivated for a while. The problem was that while the user started to drag and just held an UIScrollView instance, if I took a screenshot by pressing a home button and a power button, then any of scrollViewDidEndDragging and scrollViewDidEndDecelerating didn't get called. So the app became messed up. I implemented a UIApplicationWillResignActiveNotification method in my UIViewController, but it didn't get called after taking a screenshot. How can I catch any kind of interruption that disturbs a regular flow of events? Sometimes, touchesEnd and touchesCanceled didn't get called too due to an interruption. Thank you.
