• Android app after update: crashes on Motorola Cliq with weird stacktrace

  - by sandis

  So after updating my app on the market I am getting reports from motorola cliq-users that my app crashes on start. The stacktrace is below, and is not very helpful since it does not go trough my app! Unfortunately I have no access to a motorola cliq-phone by myself, and I have changed too many things in this update to know what is causing the trouble. Have anyone of you guys run into the same problem? I would very much appreciate help with this problem! 05-26 11:44:06.521 I/PacketReader( 116): Got the features element 05-26 11:44:06.941 W/WindowManager( 86): No window to dispatch pointer action 0 05-26 11:44:07.381 W/WindowManager( 86): No window to dispatch pointer action 1 05-26 11:44:07.691 W/ActivityManager( 86): Launch timeout has expired, giving up wake lock! 05-26 11:44:07.931 W/ActivityManager( 86): Activity idle timeout for HistoryRecord{43714db8 {my.package/my.package.Main}} 05-26 11:44:08.531 E/AndroidRuntime( 565): Uncaught handler: thread main exiting due to uncaught exception 05-26 11:44:08.541 E/AndroidRuntime( 565): java.lang.RuntimeException: Unable to start activity ComponentInfo{my.packageC/my.package.Main}: java.lang.NullPointerException 05-26 11:44:08.541 E/AndroidRuntime( 565): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2297) 05-26 11:44:08.541 E/AndroidRuntime( 565): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2313) 05-26 11:44:08.541 E/AndroidRuntime( 565): at android.app.ActivityThread.access$2000(ActivityThread.java:115) 05-26 11:44:08.541 E/AndroidRuntime( 565): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1721) 05-26 11:44:08.541 E/AndroidRuntime( 565): at android.os.Handler.dispatchMessage(Handler.java:99) 05-26 11:44:08.541 E/AndroidRuntime( 565): at android.os.Looper.loop(Looper.java:123) 05-26 11:44:08.541 E/AndroidRuntime( 565): at android.app.ActivityThread.main(ActivityThread.java:3977) 05-26 11:44:08.541 E/AndroidRuntime( 565): at java.lang.reflect.Method.invokeNative(Native Method) 05-26 11:44:08.541 E/AndroidRuntime( 565): at java.lang.reflect.Method.invoke(Method.java:521) 05-26 11:44:08.541 E/AndroidRuntime( 565): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:782) 05-26 11:44:08.541 E/AndroidRuntime( 565): at com.android.internal.os.ZygoteI

• magento payment process.. how it works in general

  - by spirytus

  hi everyone, got a question and I hope this is right place to ask :).. don’t quite understand how payment works in magento. client goes to checkout and lets say wants to pay as a guest, so provides address etc. and finally gets to payment methods. Then I want clients to pay thru credit card. Already have module installed for gateway (bank?) of my choice. At that point I would expect users to be redirected to 3rd party page (bank hosted) where they giving all the details, only after being returned to my magento site with appropriate message. In magento however it seems like they need to provide cc numbers and details on magento checkout page. I don’t understand if I (or the payment module I installed) need to transfer then all the credit card details to bank? I would have to have checkout page on ssl connection and static ip right? The thing is I want to avoid touching CC numbers at any point and would love to have it done by a bank page. I like the idea of magento interface all the way without redirecting to another page though, the only problem is not sure if would be able to set it all up properly. If anyone could explain to me possible options, what is the common way to do it and how the whole process works that would be very much appreciated. I did my research and looked all over google and various forums still need someones help though. Please let me know if some parts of my question are not quite clear, will try to better explain if necessary.

• Creating a smart text generator

  - by royrules22

  I'm doing this for fun (or as 4chan says "for teh lolz") and if I learn something on the way all the better. I took an AI course almost 2 years ago now and I really enjoyed it but I managed to forget everything so this is a way to refresh that. Anyway I want to be able to generate text given a set of inputs. Basically this will read forum inputs (or maybe Twitter tweets) and then generate a comment based on the learning. Now the simplest way would be to use a Markov Chain Text Generator but I want something a little bit more complex than that as the MKC basically only learns by word order (which word is more likely to appear after word x given the input text). I'm trying to see if there's something I can do to make it a little bit more smarter. For example I want it to do something like this: Learn from a large selection of posts in a message board but don't weight it too much For each post: Learn from the other comments in that post and weigh these inputs higher Generate comment and post See what other users' reaction to your post was. If good weigh it positively so you make more posts that are similar to the one made, and vice versa if negative. It's the weighing and learning from mistakes part that I'm not sure how to implement. I thought about Artificial Neural Networks (mainly because I remember enjoying that chapter) but as far as I can tell that's mainly used to classify things (i.e. given a finite set of choices [x1...xn] which x is this given input) not really generate anything. I'm not even sure if this is possible or if it is what should I go about learning/figuring out. What algorithm is best suited for this? To those worried that I will use this as a bot to spam or provide bad answers to SO, I promise that I will not use this to provide (bad) advice or to spam for profit. I definitely will not post it's nonsensical thoughts on SO. I plan to use it for my own amusement. Thanks!

• are there java based auto-updating tools other than WebStart & Eclipse P2?

  - by DaddyB

  Hi, I am working on a java based application and we are looking to ease our deployment of updates. Up until now, we've always simply sent out new install packs & had the sysadmin's on our customer sites roll out the upgrades - painful for a large number of users. what I'd like to do is something similar to java webstart (or eclipse p2) - when the application starts, it checks for updates in a specified location and then downloads the updates prior to starting. But here's my problem - I want more control over what's done outside of the scope of plugins & jar files. For example: I'd like to be able to upate my JVM (we ship a modified version with additional security features). I need to install DLL's - possibly local to the jar files, sometimes to windows Occasiontally run MSI's to install windows components (e.g. printer drivers). I need to modify config files & the registry. I have found a few applications that support this (such as AppLifeUpdate at http://www.kineticjump.com/) but they tend to be .NET focused and it seems a bit perverse to introduce a .NET dependancy on a java application ;) I know I could write my own here, but if there is already a 3rd party library out there that supports this kind of facility, then it would make my life a lot easier. So, has anyone else had a similar problem & knows of some products I could look at? Thanks, Brian.

• calculating offer period for subscription

  - by TheVillageIdiot

  I'm maintaining a web application which deals with some kind of subscriptions. Users can to renew their subscriptions from 2 months before expiry (not earlier than that). Sometimes user does not renew before expiry and get grace period which is of 3 months. Now he can renew in these 3 months of grace period. Now the problem part. In the previous transactions of renew requests I have to show what was the offer period for that particular request (subscription start and subscription end period if renew was granted). Things are pretty simple if user renews before expiry, but I'm not able to get things straight if there is grace period specially when the subscriptions is expiring in last months of the year. Also there sometimes calculations go haywire when subscription is ending in jan or feb. All this is happening because offer period is not saved with the application anywhere (I don't know why). so if subscription is ending in 20 October 2008 and renew application is submitted in 16 January 2009 (because of grace period) the offer period should be 21 October 2008 to 20 October 2009.

• Geolocation and jQuery - Can't post results using ajax

  - by etombaugh

  I'm currently working on a project to make a location-aware site. In essence, the user comes to the page, and their location is found using the HTML5 method and then using jQuery, the location is posted to a page which saves the location/address to a codeigniter session, but if they want to update their location, or change to a different location(IE they want to use their work address as the location instead of their present address), theres a jQuery colorbox that displays and lets them type in a custom address. Everything works flawlessly to get the initial location, but when I try and get the updated location saved, I receive the error "Uncaught TypeError: Object [object DOMWindow] has no method 'lat'" which then Google Chrome references as being an error not in jQuery, but in the file for Google Maps API. Any suggestions? jQuery('.inputsubmit').click(function() { //Takes values from user submitted fields and parses them into an address string var street = jQuery('.inputaddress').val(); var city = jQuery('.inputcity').val(); var state = jQuery('.inputstate').val(); var address = street +" "+ city +", " +state; geocoder = new google.maps.Geocoder(); var geocoderresult= geocoder.geocode({'address': address}, function(results, status) { if (status == google.maps.GeocoderStatus.OK) { var newlocation = results[0].geometry.location; //Posts coordinates and address string to a CodeIgniter function to update users session information jQuery.post("somepage", {location: newlocation, address: address},function(data) { alert("Data Loaded: " + data); }); } else { alert("Geocoder failed due to: " + status); } }); }); I've tried everything I can think of to get the post to work. All of the code works up till the point, and I've commented out the post line and everything works correctly. This is one of our main website's features, to provide instant and quick results based off of location. Thanks!

• Using Facebook Login to create a user?

  - by andbeyond

  I've read this SO post which led me to this FB policy page, which seemed to include some pertinent information, but I'd like more of a community response, maybe some experienced FB API people who know the limits. My question is if I can use Facebook's Login api to, essentially, create a new user on my website. I really would just like to allow users to easily "transfer" some data from FB in order to more easily create a new account on my site. I realize, first and foremost, that I would obviously announce to the user that by click "submit" in the form, that they are creating a separate account on my site. Pertinent blocks on the policy page state: You may cache data you receive through use of the Facebook API in order to improve your application’s user experience, but you should try to keep the data up to date. This permission does not give you any rights to such data. Which doesn't look good for me, but also this: If you stop using Platform or we disable your application, you must delete all data you have received through use of the Facebook API unless: (a) it is basic account information; or (b) you have received explicit consent from the user to retain their data. Which, in my case, I would be satisfying part B. I would be asking the user's permission to retain the data, as I am simply using Facebook as a conveience to the user when creating an account. I also realize that Facebook has a registration API, but this would require a Facebook styled login form, along with my own sites login form, and I'd rather one interface, as this makes it easier for me on the front and back end. Any thoughts?

• Incorporating Devise Authentication into an already existing user structure?

  - by Kevin

  I have a fully functional authentication system with a user table that has over fifty columns. It's simple but it does hash encryption with salt, uses email instead of usernames, and has two separate kinds of users with an admin as well. I'm looking to incorporate Devise authentication into my application to beef up the extra parts like email validation, forgetting passwords, remember me tokens, etc... I just wanted to see if anyone has any advice or problems they've encountered when incorporating Devise into an already existing user structure. The essential fields in my user model are: t.string :first_name, :null => false t.string :last_name, :null => false t.string :email, :null => false t.string :hashed_password t.string :salt t.boolean :is_userA, :default => false t.boolean :is_userB, :default => false t.boolean :is_admin, :default => false t.boolean :active, :default => true t.timestamps For reference sake, here's the Devise fields from the migration: t.database_authenticatable :null => false t.confirmable t.recoverable t.rememberable t.trackable That eventually turn into these actual fields in the schema: t.string "email", :default => "", :null => false t.string "encrypted_password", :limit => 128, :default => "", :null => false t.string "password_salt", :default => "", :null => false t.string "confirmation_token" t.datetime "confirmed_at" t.datetime "confirmation_sent_at" t.string "reset_password_token" t.string "remember_token" t.datetime "remember_created_at" t.integer "sign_in_count", :default => 0 t.datetime "current_sign_in_at" t.datetime "last_sign_in_at" t.string "current_sign_in_ip" t.string "last_sign_in_ip" t.datetime "created_at" t.datetime "updated_at" What do you guys recommend? Do I just remove email, hashed_password, and salt from my migration and put in the 5 Devise migration fields and everything will be OK or do I need to do something else?

• Symfony: How to hide form fields from display and then set values for them in the action class

  - by Tom

  I am fairly new to symfony and I have 2 fields relating to my table "Pages"; created_by and updated_by. These are related to the users table (sfGuardUser) as foreign keys. I want these to be hidden from the edit/new forms so I have set up the generator.yml file to not display these fields: form: display: General: [name, template_id] Meta: [meta_title, meta_description, meta_keywords] Now I need to set the fields on the save. I have been searching for how to do this all day and tried a hundred methods. The method I have got working is this, in the actions class: protected function processForm(sfWebRequest $request, sfForm $form) { $form_params = $request->getParameter($form->getName()); $form_params['updated_by'] = $this->getUser()->getGuardUser()->getId(); if ($form->getObject()->isNew()) $form_params['created_by'] = $this->getUser()->getGuardUser()->getId(); $form->bind($form_params, $request->getFiles($form->getName())); So this works. But I get the feeling that ideally I shouldnt be modifying the web request, but instead modifying the form/object directly. However I havent had any success with things like: $form->getObject()->setUpdatedBy($this->getUser()->getGuardUser()); If anyone could offer any advice on the best ways about solving this type of problem I would be very grateful. Thanks, Tom

• Browser relative positioning with jQuery and CutyCapt

  - by Acoustic

  I've been using CutyCapt to take screen shots of several web pages with great success. My challenge now is to paint a few dots on those screen shots that represent where a user clicked. CutyCapt goes through a process of resizing the web page to the scroll width before taking a screen shot. That's extremely useful because you only get content and not much (if any) of the page's background. My challenge is trying to map a user's mouse X coordinates to the screen shot. Obviously users have different screen resolutions and have their browser window open to different sizes. The image below shows 3 examples with the same logo. Assume, for example, that the logo is 10 pixels to the left edge of the content area (in red). In each of these cases, and for any resolution, I need a JavaScript routine that will calculate that the logo's X coordinate is 10. Again, the challenge (I think) is differing resolutions. In the center-aligned examples, the logo's position, as measured from the left edge of the browser (in black), differs with changing browser size. The left-aligned example should be simple as the logo never moves as the screen resizes. Can anyone think of a way to calculate the scrollable width of a page? In other words, I'm looking for a JavaScript solution to calculate the minimum width of the browser window before a horizontal scroll bar shows up. Thanks for your help!

• Multiple calls to data service from SL3?

  - by Chris

  I have an SL3 that makes asynchronous calls to a data service. Basically, there is a treeview that is bound to a collection of objects. The idea is that as a user selects a specific treeviewitem, a call is made to the data service, with a parameter specific to the selected treeviewitem being passed to the corresponding web method in the data service. The data service returns data back to the SL3 client, and the client presents the data to the user. This works well. The problem is that when users start to navigate through the treeview using the arrow keys on their keyboard, they could press the down arrow key, for example, 10 times, and 10 calls will be made to the data service, and then each of the 10 items will be displayed to the user momentarily, until finishing with the data for the most recently selected treeview item. So - onto the question. How can I put in some form of delay, to allow someone to navigate quickly through a treeview, then, once then stop at a certain treeviewitem, a call is made to the data service? Thanks for any suggestions. Chris

• best way to add and delete text lines with jquery product configurator

  - by Daniel White

  I am creating a product configurator with Jquery. My users can add custom text lines to their product. So you could create say... 4 text lines with custom text. I need to know what the best way to add and delete these lines would be. Currently I have the following code for adding lines... //Add Text Button $('a#addText').live('click', function(event) { event.preventDefault(); //Scroll up the text editor $('.textOptions').slideUp(); $('#customText').val(''); //count how many items are in the ul textList var textItems = $('ul#textList li').size(); var nextNumber = textItems + 1; if(textItems <= 5) { //Change input to reflect current text being changed $('input#currentTextNumber').val(nextNumber); //Append a UL Item to the textList $('ul#textList').append('<li id="textItem'+nextNumber+'">Text Line. +$5.00 <a class="deleteTextItem" href="'+nextNumber+'">Delete</a></li>'); //Scroll down the text editor $('.textOptions').slideDown(); }else { alert('you can have a maximum of 6 textual inputs!'); } }); I'm probably not doing this the best way, but basically i have an empty UL list to start with. So when they click "Add Text Line" it finds out how many list elements are in the unordered list, adds a value of 1 to that and places a new list element with the id TextItem1 or TextItem2 or whatever number we're on. The problem i'm running into is that when you click delete item, it screws everything up because when you add an item again all the numbers aren't correct. I thought about writing some kind of logic that says all the numbers above the one you want deleted get 1 subtracted from their value and all the numbers below stay the same. But I think i'm just going about this the wrong way. Any suggestions on the easiest way to add and delete these text lines is appreciated.

• Grails Deployment - Fastest way to get deployed?

  - by gav

  Hi All, If anyone has or is running a Grails application on their server I would appreciate some details on where to go after creating the WAR. Background I chose grails because with Google App Engine and the App Engine Plugin deployment should have been trivial. This issue is that there is a bug which makes any application pretty much unusable, I wish this had been more prominent so I didn't have to get to the point of seeing the error myself before I was aware of it. The next option was EC2 and the Cloud Tools plugin, it seems Cloud Tools worked with grails 1.0 but doesn't work with the current 1.2.1 due to issues getting the JAR dependencies. It also seems that Cloud Tools has been succeeded by Cloud Foundry which is in beta, will cost extra money and has limited places (I signed up but haven't got an e-mail). Question My application is painfully trivial, it has a small load, small data requirements and doesn't need to scale past 5 users. How can I deploy my grails app as quickly and painlessly as possible? Specifically: Are there any hosting companies that have tomcat installed on their servers out of the box that I can sign up to and use that will just work? Do you know of any simple tutorials for getting a grails application deployed to EC2 without Cloud Tools? Thanks in advance, Gav Side-note: I picked grails because of good advice from SO, it should have been a very short time from development to deployed product except the tools for auto-deployment aren't that mature and I've never configured a server before.

• How would the 'Model' in a Rails-type webapp be implemented in a functional programming langauge?

  - by ceptorial

  In MVC web development frameworks such as Ruby on Rails, Django, and CakePHP, HTTP requests are routed to controllers, which fetch objects which are usually persisted to a backend database store. These objects represent things like users, blog posts, etc., and often contain logic within their methods for permissions, fetching and/or mutating other objects, validation, etc. These frameworks are all very much object oriented. I've been reading up recently on functional programming and it seems to tout tremendous benefits such as testability, conciseness, modularity, etc. However most of the examples I've seen for functional programming implement trivial functionality like quicksort or the fibonnacci sequence, not complex webapps. I've looked at a few 'functional' web frameworks, and they all seem to implement the view and controller just fine, but largely skip over the whole 'model' and 'persistence' part. (I'm talking more about frameworks like Compojure which are supposed to be purely functional, versus something Lift which conveniently seems to use the OO part of Scala for the model -- but correct me if I'm wrong here.) I haven't seen a good explanation of how functional programming can be used to provide the metaphor that OO programming provides, i.e. tables map to objects, and objects can have methods which provide powerful, encapsulated logic such as permissioning and validation. Also the whole concept of using SQL queries to persist data seems to violate the whole 'side effects' concept. Could someone provide an explanation of how the 'model' layer would be implemented in a functionally programmed web framework?

• Why is it not good to use $_SESSION in Restful Implementations?

  - by keisimone

  Original Question: i read that for RESTful websites. it is not good to use $_SESSION. Why is it not good? how then do i properly authenticate users without looking up database all the time to check for the user's roles? I read that it is not good to use $_SESSION. http://www.recessframework.org/page/towards-restful-php-5-basic-tips I am creating a WEBSITE, not web service in PHP. and i am trying to make it more RESTful. at least in spirit. right now i am rewriting all the action to use Form tags POST and add in a hidden value called _method which would be "delete" for deleting action and "put" for updating action. however, i am not sure why it is recommended NOT to use $_SESSION. i would like to know why and what can i do to improve. To allow easy authorization checking, what i did was to after logging in the user, the username is stored in the $_SESSION. Everytime the user navigates to a page, the page would check if the username is stored inside $_SESSION and then based on the $_SESSION retrieves all the info including privileges from the database and then evaluates the authorization to access the page based on the info retrieved. Is the way I am implementing bad? not RESTful? how do i improve performance and security? Thank you.

• What kinds of problems are most likely to occur? (question rewritten)

  - by ChrisC

  If I wrote 1) a C# SQL db app (a simple program consisting of a gui over some forms with logic for interfacing with the sql db) 2) for home use, that doesn't do any network communication 3) that uses a simple, reliable, and appropriate sql db 4) whose gui is properly separated from the logic 5) that has complete and dependable input data validation 6) that has been completely tested so that 100% of logic bugs were eliminated ... and then if the program was installed and run by random users on their random Windows computers Q1) What types of technical (non-procedural) problems and support situations are most likely to occur, and how likely are they? Q2) Are there more/other things I could do in the first place to prevent those problems and also minimize the amount of user support required? I know some answers will apply to my specific platforms (C#, SQL, Windows, etc) and some won't. Please be as specific as is possible. Mitch Wheat gave me some very valuable advice below, but I'm now offering the bounty because I am hoping to get a better picture of the kinds of things that I'm most reasonably likely to encounter.

• Creating a draft version of the page before publishing in Drupal 6?

  - by Marco

  I've been looking for a good way to handle revisions in Drupal, but I am yet to succeed. For some reason there is no built in way to save a draft (that I've found so far), and the modules I've tried so far do not seem to fully work. First I tried save_as_draft, which seemed to do almost what I wanted, and if I'm not mistaken, also handles CCK fields. Sadly it seems to be broken somehow, so I can't edit a page once I've saved it as a draft.. maybe I could fix it by going through the code, but that would not be my preferred solution. The other module I tried is aptly named draft, but from what I can tell, this module only handles the title and body fields, and does this in a way that appear odd to me. Is there some common practice to solve this? I couldn't imagine that nobody had to solve this before, but I haven't found any good solution to it yet. Clarification I need this functionality for already existing content, that is, I want to be able to create and edit a draft version of an already published page, while the "old" version would still be available to anonymous users.

  Hi all. I'm parsing HTTP data directly from packets (either TCP reconstructed or not, you can assume it is). I'm looking for the best way to parse HTTP as accurately as possible. The main issue here is the HTTP header. Looking at the basic RFC of HTTP/1.1, it seems that HTTP header parsing would be complex. The RFC describes very complex regular expressions for different parts of the header. Should I write these regular expressions to parse the different parts of the HTTP header? The basic parsing I've written so far for HTTP header is for the generic HTTP header: message-header = field-name ":" [ field-value ] And I've included replacing inner LWS with SP and repeating headers with the same field-name with comma separated values as described in section 4.2. However, looking at section 14.9 for example would show that in order to parse the different parts of the field-value I need a much more complex parsing scheme. How do you suggest I should handle the complex parts of HTTP parsing (specifically the field-value) assuming I want to give the parser users the full capabilities of HTTP and to parse every part of HTTP? Design suggestions for this would also be appreciated. Thanks.

  Hi I am new to coldbox and working on a guestbook messaging forum. does anyone know how I can apply some rule in coldbox to show edit and delete for specified users of admin or user in the edit page. I am not sure how to specify this as I already have my rules here as shown in securityRules.xml: SecurityRules.XML <?xml version="1.0" encoding="UTF-8"?> <!-- Declare as many rule elements as you want, order is important Remember that the securelist can contain a list of regular expression if you want ex: All events in the user handler user\..* ex: All events .* ex: All events that start with admin ^admin If you are not using regular expression, just write the text that can be found in an event. <whitelist>ehSecurity\.dspLogin,ehSecurity\.doLogin,ehSecurity\.dspLogoff</whitelist> --> <rules> <rule> <whitelist>^entries,ehSecurity\..*,registry\..*</whitelist> <securelist></securelist> <roles>admin</roles> <permissions>read,write</permissions> <redirect>ehSecurity.dspLogin</redirect> </rule> <rule> <whitelist>^entries,ehSecurity\..*,main\..*,^registry</whitelist> <securelist></securelist> <roles>author,admin</roles> <permissions>read</permissions> <redirect>ehSecurity.dspLogin</redirect> </rule> </rules>

• Sphinx - Python modules, classes and functions documentation

  - by user343934

  Hi everyone, I am trying to document my small project through sphinx which im recently trying to get familiar with. I read some tutorials and sphinx documentation but couldn't make it. Setup and configurations are ok! just have problems in using sphinx in a technical way. My table of content should look like this --- Overview .....Contents ----Configuration ....Contents ---- System Requirements .....Contents ---- How to use .....Contents ---- Modules ..... Index ......Display ----Help ......Content Moreover my focus is on Modules with docstrings. Details of Modules are Directory:- c:/wamp/www/project/ ----- Index.py >> Class HtmlTemplate: .... def header(): .... def body(): .... def form(): .... def header(): .... __init_main: ##inline function ----- display.py >> Class MainDisplay: .... def execute(): .... def display(): .... def tree(): .... __init_main: ##inline function My Documentation Directory:- c:/users/abc/Desktop/Documentation/doc/ --- _build --- _static --- _templates --- conf.py --- index.rst I have added Modules directory to the system environment and edited index.rst with following codes just to test Table of content. But i couldn't extract docstring directly Index.rst T-Alignment Documentation The documentation covers general overview of the application covering functionalities and requirements in details. To know how to use application its better to go through the documentation. .. _overview: Overview .. _System Requirement: System Requirement Seq-alignment tools can be used in varied systems base on whether all intermediary applications are available or not like in Windows, Mac, Linux and UNIX. But, it has been tested on the Windows working under a beta version. System Applications Server .. _Configuration:: Configuration Basic steps in configuration involves in following categories Environment variables Apache setting .. _Modules:: Modules How can i continue from here... Moreover, i am just a beginner to sphinx documentation tool I need your suggestions to brings my modules docstring to my documentation page Thanks

• How to display my server's current response time to an average user

  - by Jason

  Sorry, I'm not really sure of the right way to ask this one so bear with me... We have a web application that runs on a set of servers at a data center (not in our offices) We want to be able to somehow 'advertise' to our clients/users that the availability or response time of our servers has met a standard throughout the day. I am being asked to come up with a standard metric that we can easily advertise on our login screen that shows current "standard response time" checked every x minutes. My thinking is that I need to capture something like the results of a traceroute from a server (either in our office, amazon, etc..) to one of the data center servers and come up with a Red/Yellow/Green type of a notifier for the login screen to let the user know that our tests are responding normally and if they are having delay issues it could be their network or connection to the internet. We have lots of clients in rural areas that have poor connectivity and we are trying to let them know any slowness might be on their end, not ours. I've got the LAMP stack to work with, but this could also be some other system all together as long as it can update the main server with the results. I already have pingdom reports that are available, but that's a bit more than people want to read sometimes. Any ideas on what I can do?

• User preferences using SQL and JavaScript

  - by Shyam

  Hi, I am using Server Side JavaScript - yes, I am actually using Server Side JavaScript. To complexify things even more, I use Oracle as a backend database (10g). With some crazy XSLT and mutant-like HTML generation, I can build really fancy web forms - yes, I am aware of Rails and other likewise frameworks and I choose the path of horror instead. I have no JQuery or other fancy framework at my disposal, just plain ol' JavaScript that should be supported by the underlying engine called Mozilla Rhino. Yes, it is insane and I love it. So, I have a bunch of tables at my disposal and some of them are filled with associative keys that link to values. As I am a people pleaser, I want to add some nifty user-preference driven solutions. My users have all an unique user_id and this user_id is available during the entire session. My initial idea is to have a user preference table, where I have "three" columns: user_id, feature and pref_string. Using a delimiter, such as : or - (haven't thought about a suitable one yet), I could like store a bunch of preferences as a list and store its elements inside an array using the .split-method (similar like the PHP-explode function). The feature column could be like the table name or some identifier for the "feature" i want to link preferences too. I hate hardcoding objects, especially as I want to be able to back these up and reuse this functionality application-wide. Of course I would love better ideas, just keep in mind I cannot just add a library that easily. These preferences could be like "joined" to the table, so I can query it and use its values. I hope it doesn't sounds too complex, because well.. its basically something really simple I need. Thanks!

• realtime visitors with nodejs & redis & socket.io & php

  - by orhan bengisu

  I am new to these tecnologies. I want to get realtime visitor for each products for my site. I mean a notify like "X users seeing this product". Whenever an user connects to a product counter will be increased for this product and when disconnects counter will be decreased just for this product. I tried to search a lots of documents but i got confused. I am using Predis Library for PHP. What i have done may totaly be wrong. I am not sure Where to put createClient , When to subscribe & When to unsubscribe. What I have done yet: On product detail page: $key = "product_views_".$product_id; $counter = $redis->incr($key); $redis->publish("productCounter", json_encode(array("product_id"=> "1000", "counter"=> $counter ))); In app.js var app = require('express')() , server = require('http').createServer(app) , socket = require('socket.io').listen(server,{ log: false }) , url = require('url') , http= require('http') , qs = require('querystring') ,redis = require("redis"); var connected_socket = 0; server.listen(8080); var productCounter = redis.createClient(); productCounter.subscribe("productCounter"); productCounter.on("message", function(channel, message){ console.log("%s, the message : %s", channel, message); io.sockets.emit(channel,message); } productCounter.on("unsubscribe", function(){ //I think to decrease counter here, Shold I? and How? } io.sockets.on('connection', function (socket) { connected_socket++; socket_id = socket.id; console.log("["+socket_id+"] connected"); socket.on('disconnect', function (socket) { connected_socket--; console.log("Client disconnected"); productCounter.unsubscribe("productCounter"); }); }) Thanks a lot for your answers!
