• Anyone up to creating a tomcat based alternative for GAE?

  - by bach

  Hi, If we had the possibility to run GAE app without any code change on our servlet engine that would be great because: in case that google changes their billing policy we can just jump to our own server or in case their current policy doesn't fit our app needs we can do stuff which is not allowed in the GAE, compromising a 1 JVM, 1 DB We don't actually need a distributed system but more of a realtime system with synchronize, true locking mechanisms, other servers/software installed on the server machine, socket interface etc... Such a package should include at least: TomCat (or equivalent) DataNucleus Access Platform (Task Queue service) Any idea if it's easy to get such a thing or if it's already exist somewhere? Thanks

• Ipad, closed environment and threat to privacy

  - by Akshay Bhat

  I had an unusual question about ipad, Since ipad environment is closed and does not allows installation of diagnostic and security related programs. How can then we be sure that any of the software installed on ipad is not infringing upon our privacy by doing stuff such as homing back information, etc. We cant install a packet tracer or any other software to check for attacks on privacy. Also given Apples poor track record (the safari browser was broken in one day), I don't think trusting apple solely would be a good idea. This might not seem to be a big issue but for business users it would be a significant concern.

• set current user in asp.net mvc

  - by Tomh

  Hey guys, I'm not sure if this is the best way to do it, but I want to keep a user object alive during all requests of the current user. From reading several resources I learned that you should create your own IPrinciple which holds this. But I don't want to trigger the database every authentication request. Any recommendations on how to handle this? Is caching the db request a good idea? protected void Application_AuthenticateRequest(Object sender, EventArgs e) { HttpCookie authCookie = Request.Cookies[FormsAuthentication.FormsCookieName]; if (authCookie != null) { FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value); User user; using (HgDataContext hg = new HgDataContext()) { if (Session["user"] != null) { user = (from u in hg.Users where u.EmailAddress == authTicket.Name select u).Single(); } else { user = Session["user"] as User; } } var principal = new HgPrincipal(user); Context.User = principal; } }

• http/html/ajax: show result before site is completely processed

  - by chris

  hi! I am looking for a way to show in a webapp in front of a task a wait-message and after it hide the message. The task is running a longer time. I dont know if it is possible at all. The problem is, so far I can see, that the site will be returned to the users browser AFTER the task is completed because the task is part of the site as a inline code replaces by the webserver interpreter (no matter if php, perl or whatever). The only solution I can imagine is to parallel the task with threads or processes and requery the state with ajax in the website. Any idea to do it less complex? Thanks for help! regards chris

• TextField instance inside a button created in a separate layer in Flash is null in Flex

  - by php html

  I've created an button object in flash. The button contains 2 layers. One is the background image and on top of it is a textField. The textfield is dynamic. I use the button inside a movieclip and I export it in a SWC. The I'm trying to use it in flex. I'm trying to do this: var myComponent:MyComponent = new MyComponent(); myComponent.button01.theTextField.text = "Caption"; I get and instance of the button, but the instance of the textField is null and I'm not able to change the text(but the default text appears onscreen). Does anyone has any idea what is wrong? Here is the button timeline(Layer 2 contains the textfield, and the textfield instance is named theTextField):

• Is it possible to build a JPA entity by extending a POJO?

  - by Freiheit

  Lets say I have the following POJO: public class MyThing { private int myNumber; private String myData; //assume getter/setter methods } Is it now possible to extend this POJO as a JPA entity? @Entity @Table(name = "my_thing") public class MyThingEntity extends MyThing implements Serializable { @Column(name = "my_number") //????????? @Column(name = "my_data") //???????? } I want to keep the POJO separate from the JPA entity. The POJO lives in a different project and is often used without a persistence layer, my project wants to persist it in a database and do so without the overhead of mapping from a POJO to an entity and back. I understand that JPA entities are POJOs, but in order to use it I would have to include a library that implements javax.persistence and the other projects using the same base object have no use for a persistence layer. Is this possible? Is this a good idea?

• ToolStripComboBox.SelectedItem change does not propagate to binding source

  - by Marius

  My binding is set up as this: _selectXAxisUnitViewModelBindingSource = new BindingSource(); _selectXAxisUnitViewModelBindingSource.DataSource = typeof(SelectXAxisUnitViewModel); _selectedUnitComboBoxBindingSource = new BindingSource(); _selectedUnitComboBoxBindingSource.DataSource = _selectXAxisUnitViewModelBindingSource; _selectedUnitComboBoxBindingSource.DataMember = "AvailableUnits"; _selectedUnitComboBox.ComboBox.DataSource = _selectedUnitComboBoxBindingSource; _selectedUnitComboBox.ComboBox.DisplayMember = String.Empty; _selectedUnitComboBox.ComboBox.ValueMember = String.Empty; _selectedUnitComboBox.ComboBox.DataBindings.Add("SelectedItem", _selectXAxisUnitViewModelBindingSource, "SelectedUnit", true, DataSourceUpdateMode.OnPropertyChanged); // this is a bug in the .Net framework: http://connect.microsoft.com/VisualStudio/feedback/details/473777/toolstripcombobox-nested-on-toolstripdropdownbutton-not-getting-bindingcontext _selectedUnitComboBox.ComboBox.BindingContext = this.BindingContext; The property "AvailableUnits" is a collection of strings and the "SelectedUnit" is a string-property. Now the dropdown list is populated as expected, but when I select and item in the list, the change is not propagated to the binding source. Any idea what I am doing wrong?

My parents have had a business for 20 years and have finally decided to get a website! As im studying IT and Business i said id get it done for them.

• Using Java server-side with PHP front-end

  - by Storm

  Hi!  Does anyone have a real-world experience in building such a project? I'd like to move away questions about "is it good idea or not", but focus on possible solutions. I see one simple way - HTTP GET/POST + xml/json - and one more elegant - AJAX/DWR. As for the first one - I understand that it is possible, but needs quite a lot coding. As for second way - is it possible to use Java DWR engine with PHP front-end? Is DWR language-independent for client side (as it uses just JavaScript)?  Would it be a problem, that client page was generated by one web server (for example, apache+php) and served on server-side by another (for example, tomcat)? I suspect, that Tomcat will complain about sessions. Can this problem be fixed with allowing cross-domain AJAX? Thank you in advance. Denis.

• ASP.NET site freezing up, showing odd text at top of the page while loading, on one server

  - by MGOwen

  I have various servers (dev, 2 x test, 2 x prod) running the same asp.net site. The test and prod servers are in load-balanced pairs. One of these pairs is exhibiting some kind of (super) slowdown or freezing every other page load or so. Sometimes a line of text appears at the very top of the page which looks something like: 00 OK Date: Thu, 01 Apr 2010 01:50:09 GMT Server: Microsoft-IIS/6.0 X-Powered_By: ASP.NET X-AspNet-Version:2.0.50727 Cache-Control:private Content-Type:text/html; charset=ut (the beginning and end are "cut off".) Has anyone seen anything like this before? Any idea what it means or what's causing it?

• Justified navigation buttons

  - by Kaivosukeltaja

  I'm trying to create the primary navigation menu for a website that will have a variable amount of primary menu items. The navigation bar is horizontal and has a width of 738px. I would like to have the leftmost item 18px from the left and the rightmost item 18px from the right edge of the element, with the other menu items spread evenly between them. I'm using a tableless layout. So far I haven't been able to make it work exactly like I want. Setting margin: auto doesn't seem to help, and I can't keep the 18px margin on both sides using a table. One idea was to use text-align: justify but it doesn't justify single lines. Is there a simple or less simple way of doing this, or am I going to have to ask the AD to relax his visual requirements?

• Getting text from image on ios (image processing)

  - by Vikram.exe

  Hi, I am thinking of making an application that requires extracting TEXT from an image. I haven't done any thing similar and I don't want to implement the whole stuff on my own. Is there any known library or open source code (supported for ios, objective-C) which can help me in extracting the text from the image. A basic source code will also do (I will try to modify it as per my need). Kindly let me know if some one has any idea on this. Thanks, Vikram

• How to represent double values as circles in a 2d matrix in java

  - by marco

  Hello, so I want to write a matrix explorer which enables me to reorder rows and columns of a matrix. For this porpouse I used the Jtable class. Now the problem that I have is that it is very difficult to reorder a matrix by looking at double values, so I would like to print the matrix not with the double values but with circles in which the radius of the circle represents the value. So that I can tell the difference between big values and small values quicker. Anybody has any idea how I can turn this double values into filled circles with JTable or any table class for that matter?

• mvc components in codeigniter?

  - by ajsie

  in yii i could have mvc components (acts like an own application). could i have this too in codeigniter? eg. in SYSTEM/APPLICATION have a folder called COMPONENTS and in there i put stand-alone applications that would be a part of the application. components like ADDRESS BOOK, MAIL, TWITTER and so on. every component folder has folders like: models, views, controllers, config etc. so a component model extends the application model which in turn extends system's (code igniter) model. the same goes for view and controller. i've already got a lot of these components which i want to use in codeigniter. is it good idea to place them as i said in SYSTEM/APPLICATION/COMPONENTS or is there best practice for this?

• Shark tool on iphone crashes

  - by Joey

  Hi, I am trying to use Shark to profile my app. However, it crashes after I hit "stop" and it analyzes and then goes to "load session". Only once when I decided not to select my app but chose to target "everything" did it actually display some trace. However, I could not reproduce this case. Does anyone have any idea what might be going wrong? Could it be something to do with the wrong version of Shark or my SDK or some other detail? I have the latest SDK and am running 3.1.3 on the phone. The various documentation I've found on google or via Apple's docs don't seem to be terribly helpful, so if anyone has found some that's useful, I'd love to see it. Thanks.

• VBA Macro On Timer style to run code every set number of seconds, i.e. 120 seconds

  - by FinancialRadDeveloper

  I have a need to run a piece of code every 120 seconds. I am looking for an easy way to do this in VBA. I know that it would be possible to get the timer value from the Auto_Open event to prevent having to use a magic number, but I can't quite get how to fire off a timer to get something to run every 120 seconds. I don't really want to use an infinite loop with a sleep if I can avoid it.

• php regex to remove HTML

  - by Me1000

  Before we start, strip_tags() doesn't work. now, I've got some data that needs to be parsed, the problem is, I need to get rid of all the HTML that has been formated very strangely. the tags look like this: (notice the spaces) < p > blah blah blah < / p > < a href= " link.html " > blah blah blah < /a > All the regexs I've been trying aren't working, and I don't know enough about regex formating to make them work. I don't care about preserving anything inside of the tags, and would prefer to get rid of the text inside a link if I could. Anyone have any idea? (I really need to just sit down and learn regular expressions one day)

• Put text input inside label for radio button?

  - by Martijn

  I'm trying to make a radio group specifying a bunch of options, and an extra option "other" with a text input to specify. The code for this particular radio button I'm using is <input type='radio' name='RadioInput' value='Other' id='RadioInput_Other' /> <label for='RadioInput_Other'>Ohter: <input type='text' name='RadioInput_Other_Value' id='RadioInput_Other_Value' value='' /> </label> The idea is that if you give focus to the text input, the radio button corresponding to it is selected. The code above almost does this (since the text input is inside the label). However, it also shifts focus to the radio button (which is annoying, since whatever you type next is lost). Is there any way to prevent this using XHTML1.0 / CSS2? Preferably without using javascript.

• Sanitize Content: removing markup from Amazon's content

  - by StackOverflowNewbie

  I'm using Amazon Web Service to get product descriptions of various items. The problem is that Amazon's content contains mark up that is sometimes destructive to the layout of my web page (e.g. unclosed DIVs, etc.). I want to sanitize the content I get from Amazon. My solution would be to do the following (my initial list so far): Remove unnecessary tags such as div, span, etc. while keeping tags like p, ul, ol, etc. Remove all attributes from all the tags (e.g. seems like there are style attributes in some of the tags) Remove excess white space (e.g. multiple spaces, carriage returns, new lines, tabs, etc.) Etc. Before I go off trying to build my solution, I'm wondering if anyone has a better idea (or an already existing solution). Thanks.

• Help needed with MySQL query to join data spanning multiple tables with data used as column names

  - by gurun8

  I need a little help putting together a SQL query that will give me the following resultsets: and The data model looks like this: The tricky part for me is that the columns to the right of the "Product" in the resultset aren't really columns in the database but rather key/value pairs spanned across the data model. Table data is as follows: My apologies in advance for the image heavy question and the image quality. This just seemed like the easiest way to convey the information. It'll probably take someone less time to write the query statement to achieve the results than it did for me to assemble this question. By the way, the "product_option" table image is truncated but it illustrated the general idea of the data structure. The MySQL server version is 5.1.45.

• What's the big difference between those two binary files?

  - by Lela Dax

  These are two files (contained in the tar.bz2) that were generated using a just-in-time compiler for a game engine. The generated code from ui-linux.bin is from a x86_64 gcc compiler and the ui-windows.bin from the same brand of compiler but targetting win x86_64 (mingw-w64). I've attempted to debug a problem that occurs only on the windows version and i stumbled upon what it seems to be different end-binary code. However, the input assembly code was virtually identical (only difference being pointer representations as int). (there's theoretically no winabi/unixabi conflict since that's taken care of by an attribute flag on certain declarations involved). Any idea what it might be that makes these two binary codes different? The C for the mini-compiler and base assembly producing it appears compatible at first glance. http://www0.org/vm/bins.tar.bz2

• How can you toggle between two sets of values per data series in flot?

  - by Jedidja

  flot has built-in support for multiple data series (sample code) and also dual-axis (sample code). Assuming multiple data series (water, electricity, etc) that each have an amount (usage) and a dollar value (charge for that usage), what would the best way be to to use flot to display either the amount or dollar values for all the data series, while still supporting toggling display for each individual series? The idea is to send down all the data in one GET request and then let the client take care of everything else in Javascript. Ideally we could use triplets somehow {date, amount, charge}, and then possibly split that into two arrays for flot.

• Click GEvent.addListener with jquery

  - by Jason

  Created a google map with GMap2 and put pinpoints on there that open up a balloon with the address when the pinpoint is clicked. I would like users to be able to click text on the page itself and use jquery to open up the corresponding balloon. However I can't figure out the ID to use to call a jquery click event. Basically I've got a store listing down the left side and when user clicks store name I want it to open up the corresponding balloon. GEvent.addListener(marker_500, "click", function () { map.openInfoWindowHtml(point, myHtml); } Any idea what element tied to this click event is? Tried $("#marker_500").click(); And that doesn't work. Also tried alerting $(this).attr('id'); inside the click function and that is undefined. thanks jason
