• Possible to split one JAX-WS service across multiple source files?

  - by Rob S.

  Hi everyone, Is it possible to split a web service in to multiple classes and still provide a single path to the web service? I know this isn't possible because of the duplicate url-pattern values. It sort of illustrates where we're wanting to go :) <endpoint name="OneBigService" implementation="SmallImpl1" url-pattern="/OneBigService"/> <endpoint name="OneBigService" implementation="SmallImpl2" url-pattern="/OneBigService"/> Basically, how do avoid having one monolithic @WebService class? Thanks! Rob

• convert any language into PHP sourcecode

  - by dreftymac

  Question: Is there any such thing as a programming language (other than an esoteric language such as BrainF@#$, or the languages PHP or VB) that you can "compile" into non-obfuscated PHP source code? Rationale: Swip wants to generate ordinary PHP code because it is so ubiquitous for the types of projects swip wants to do. Unfortunately swip would like to actually avoid writing PHP -- strange but true! Swip is crazy enough to want to generate PHP source code without having to type any PHP into Swip's editor.

• How can I tell JWebUnit to contact specific Selenium servers

  - by Peter Tillemans

  We want to run selenium backed jwebunit tests from our hudson server. We have a couple of selenium rc servers already on our network which I'd like to reuse. However how can I configure jwebunit to use those servers as I would like to avoid installing a slenium rc server on the hudson. Building is already work enough without starting/stopping firefoxes.

• ASP .NET 4.0 How do I Redirect/Override the default CDN path for ScriptManager when EnableCDN=true

  - by plattnum

  I am using the EnableCdn=true in my ScriptManager so that WebResource.axd and ScriptResource.axd are overridden with static links to JS libraries at the MS CDN service as follows: <asp:ScriptManager ID="ScriptManager1" runat="server" EnableCdn="true" /> How do I override the CDN URLs or service so that I can retrieve the scripts over HTTPS from the MS CDN service rather than HTTP to avoid the browser mixed mode message? or for that matter a different or my own CDN service entirely.

• Retrieving the URL in Django template language

  - by Vernon

  In a Django template, how could I refer to the URL. I want to use it in static pages, to avoid having live links to the current page. Is there a way to do this with the Django template language or do I have to use JavaScript to do it? I would like to do something like {% if current_url == "/about/" %} About {% else %} <a href='/about/'>About</a> {% endif %} I'm using it for a simple blog, so there are no views written for those pages.

• clearTimeout not working in javascript autocomplete script

  - by Travis

  I am using the following code as part of an autocomplete script to avoid hammering the server with every keystroke: var that = this; textInput.bind("keyup", function() { clearTimeout(that.timer); that.timer = setTimeout (that.doStuff(), 2000); }); Unfortunately, this does not clear the old timers. They still all execute. Does anyone know what I'm missing? Thanks!

• Optimizing tasks to reduce CPU in a trading application

  - by Joel

  Hello, I have designed a trading application that handles customers stocks investment portfolio. I am using two datastore kinds: Stocks - Contains unique stock name and its daily percent change. UserTransactions - Contains information regarding a specific purchase of a stock made by a user : the value of the purchase along with a reference to Stock for the current purchase. db.Model python modules: class Stocks (db.Model): stockname = db.StringProperty(multiline=True) dailyPercentChange=db.FloatProperty(default=1.0) class UserTransactions (db.Model): buyer = db.UserProperty() value=db.FloatProperty() stockref = db.ReferenceProperty(Stocks) Once an hour I need to update the database: update the daily percent change in Stocks and then update the value of all entities in UserTransactions that refer to that stock. The following python module iterates over all the stocks, update the dailyPercentChange property, and invoke a task to go over all UserTransactions entities which refer to the stock and update their value: Stocks.py # Iterate over all stocks in datastore for stock in Stocks.all(): # update daily percent change in datastore db.run_in_transaction(updateStockTxn, stock.key()) # create a task to update all user transactions entities referring to this stock taskqueue.add(url='/task', params={'stock_key': str(stock.key(), 'value' : self.request.get ('some_val_for_stock') }) def updateStockTxn(stock_key): #fetch the stock again - necessary to avoid concurrency updates stock = db.get(stock_key) stock.dailyPercentChange= data.get('some_val_for_stock') # I get this value from outside ... some more calculations here ... stock.put() Task.py (/task) # Amount of transaction per task amountPerCall=10 stock=db.get(self.request.get("stock_key")) # Get all user transactions which point to current stock user_transaction_query=stock.usertransactions_set cursor=self.request.get("cursor") if cursor: user_transaction_query.with_cursor(cursor) # Spawn another task if more than 10 transactions are in datastore transactions = user_transaction_query.fetch(amountPerCall) if len(transactions)==amountPerCall: taskqueue.add(url='/task', params={'stock_key': str(stock.key(), 'value' : self.request.get ('some_val_for_stock'), 'cursor': user_transaction_query.cursor() }) # Iterate over all transaction pointing to stock and update their value for transaction in transactions: db.run_in_transaction(updateUserTransactionTxn, transaction.key()) def updateUserTransactionTxn(transaction_key): #fetch the transaction again - necessary to avoid concurrency updates transaction = db.get(transaction_key) transaction.value= transaction.value* self.request.get ('some_val_for_stock') db.put(transaction) The problem: Currently the system works great, but the problem is that it is not scaling well… I have around 100 Stocks with 300 User Transactions, and I run the update every hour. In the dashboard, I see that the task.py takes around 65% of the CPU (Stock.py takes around 20%-30%) and I am using almost all of the 6.5 free CPU hours given to me by app engine. I have no problem to enable billing and pay for additional CPU, but the problem is the scaling of the system… Using 6.5 CPU hours for 100 stocks is very poor. I was wondering, given the requirements of the system as mentioned above, if there is a better and more efficient implementation (or just a small change that can help with the current implemntation) than the one presented here. Thanks!! Joel

• Is assert evil?

  - by dehmann

  The Go language creators write: Go doesn't provide assertions. (...) Programmers use them as a crutch to avoid thinking about proper error handling and reporting. What is your opinion about this?

• Outlook - check email address type

  - by Chris Gunner

  I am trying to make a macro in Outlook that will scan the To: list for a certain text string, and spit out a message if all but one (or two, etc) addresses have it. Is there a simple way to do this? Essentially, I am trying to write something that'll avoid being able to send a restricted message to a bunch of people with the string 'xyz' in the address, if one or more do not have it. AutoComplete makes this difficult, without checking through one-by-one.

• why does maven3 give up supporting application $version declaration?

  - by Bariscan

  As you see from the title, I want to ask that the case of in maven3 there is no support for $version in pom.xml anymore. Do we have to really write a constant every time in each project in every pom.xml and related configuration files again and again? How can we avoid doing this? How can we use a versioning method like $version? Many thanks in advance, Baris

• Genetic/Evolutionary algorithms and local minima/maxima problem

  - by el.gringogrande

  I have run across several posts and articles that suggests using things like simulated annealing to avoid the local minima/maxima problem. I don't understand why this would be necessary if you started out with a sufficiently large random population. Is it just another check to insure that the initial population was, in fact, sufficiently large and random? Or are those techniques just an alternative to producing a "good" initial population?

• jquery delegate table rows selector

  - by Jackob

  I have a table which may contains other inner tables (it's not possible to edit generated markup). I want to create a delegate function for row mouseenter and mouseleave which only triggers for the associated main table rows (and not inner tables rows), as following: $("#tableid").delegate("tr", "mouseenter mouseleave", function(e) { //do stuff here }); But with this selector it selects also the inner table rows, so how can I modify the selector to avoid selecting inner table rows?

• Usage of @specialized in traits

  - by paradigmatic

  I have a trait and an implementation looking like: trait Foo[A] { def bar[B >: A: Ordering]: Foo[B] } class FooImpl[A]( val a: A, val values: List[Foo[A]] ) extends Foo[A] { def bar[B >: A] = { /* concrete implementation */} } I would like to use the @specialized annotation on A and B to avoid autoboxing. Do I need to use it in both trait and implementation, only in implementation, or only in trait ?

• Can a single argument constructor with a default value be subject to implicit type conversion

  - by Richard

  I understand the use of the explicit keyword to avoid the implicit type conversions that can occur with a single argument constructor, or with a constructor that has multiple arguments of which only the first does not have a default value. However, I was wondering, does a single argument constructor with a default value behave the same as one without a default value when it comes to implicit conversions?
