• Query parameter using JS framework ?

  - by Maxim Veksler

  Hi, I seem to not be able to find implementation from the common Ajax libraries (JQuery, mootools, prototypejs...) that would allow the operation of parsing the window.location.href for request parameter. I would expect something like: $P{"param1"} == "param1_value" Am I missing something? p.s. The web does contains implementation examples for such operations

• How to implement context menu on key press instead of long click/tap

  - by takyon

  I have a ListActivity and I want to implement context menu for each of the list elements. I know that the common way to do this is to show the context menu on long click/tap. I want to know if there is a way to show the context menu for each element on a key press(preferably the menu key). To rephrase my question, how can I trigger the context menu and not the options menu by pressing the menu key(or any other key).

• PHP performance difference between passing variables method

  - by Industrial

  Hi everyone, Will there be any measurable performance difference when passing data as values instead of as reference in PHP? It seems like few people are aware of that variables can be passed as values instead of references. Is this common sense or not?

• Mutiple FK columns all pointing to the same parent table - a good idea?

  - by Randy Minder

  For those of you who live and breath database design, have you ever found compelling reasons to have multiple FK's in a table that all point to the same parent table? We recently had to deal with a situation where we had a table that contained six columns which were all FK columns to the same parent table. We're debating whether this indicates a poor design on our part or whether this is more common than we think. Thanks very much.

• Re-usable views or xibs for use with UIStoryboard

  - by Leonardo

  I find it very convenient to use storyboards, especially to have (and show) an overview of the application. However, I also find it very annoying to replicate the same code and views without the possibility to keep at least a reusable library of the most common xibs. This is especially true with UITableView and its cell. Did some of you have had any idea or best practice to share for dealing with this issue?

• Are Ruby formatted strings and interpolated strings identical in behaviour?

  - by Steve Weet

  Do the following two lines of code behave in exactly the same way despite slightly different implementations values.map{ |k,v| __send__('%s=' % k.to_s, v) } values.map{ |k,v| __send__("#{k.to_s}=", v) } The second line would be a more common ruby idiom so I was wondering why the other method was used when this was in the Rails Core which I would expect to use idiomatic ruby.

• Z-index bug with IE6.. can't seem to figure this one out

  - by Trip

  I am working on this gorgeous header here at : http://kayaskitchenbelmar.com/test/header.html Unfortunately, in IE6, the drop downs that come off of the Print and View buttons collapse on to a new line. This is because of the common z-index bug. I tried resolving this by making the parent div have a higher z-index and position relative with its child a lower z-index and position absolute, but that didn't seem to work. Possibly I'm missing something obvious? Thanks so much

• generate PHP classes from XSD?

  - by Qwerty

  Is there in the world analogues of JavaBeans or JAXB for PHP? Is it possible to generate PHP classes from XML schema? It's common practice to publish API's as XSD schemas. Java and C# guys can get advantage of this by generating classes right from XSD. Is there same tool for PHP?

• Does a syntax for this exist? In any language?

  - by Michael

  It seems pretty common to me to have an argument, in a dynamically typed language that is either an Object or a key to lookup that object. For instance when I'm working with a database I might have a method getMyRelatedStuff(person) All I really need to lookup the related stuff is the id of the person so my method could look like this in python: def getMyRelatedStuff(person_or_id): id = person_or_id.id if isinstance(person,User) else person_or_id #do some lookup Or going the other direction: def someFileStuff(file_or_name): file = file_or_name if hasattr(file,'write') else open(file_or_name)

• How to start an activity that is defined in other Android projects?

  - by qichuan

  I have defined some common Activities in a library project and want to reuse these activity in my working project. I declared my library project as Android library, use the fully-qualified name of the Activities and declare them in the AndroidManifest.xml of the new project. However, I get 'Unable to find explicit activity class' error when launching the application. Any other configurations shall I do in order to start the Activities?

• Monad in plain English? (For the OOP programmer with no FP background)

  - by fig-gnuton

  In terms that an OOP programmer would understand (without any functional programming background), what is a monad? What problem does it solve and what are the most common places it's used? EDIT: To clarify the kind of understanding I was looking for, let's say you were converting an FP application that had monads into an OOP application. What would you do to port the responsibilities of the monads into the OOP app?

• traits in php – any real world examples/best practices?

  - by Max

  Traits have been one of the biggest additions for PHP 5.4. I know the synatax and understand the idea behind traits, like horizontal code re-usage for common stuff like logging, security, caching etc. However, I still dont know yet how I would make use of traits in my projects. Are there any open source projects that already use traits? Any good articles/reading material on how to structure architectures using traits?

• When using Doxygen for C++ sources a size of font for \subsubsection is larger than for \section and

  - by sergdev

  I installed Doxygen 1.6.1. I used \section, \subsection and \subsubsection for titles in C++ sources. I surprisingly obtained titles in which \subsubsection have large font size than for \subsection and \section. How can this be fixed? CSS should be used to workaround this or can I fix my doxygen installation to obtain expected common behavior?

• Are there any lightweight analogues to CORBA/RPC for embedded programs?

  - by Mtr

  I am writing embedded applications for different hardware (avr, arm7, tms55xx…) and different rtoses (freeRTOS, rtx, dsp/bios). And every second of them needs to communicate with PC or another digital device. Sometimes interactions logic is very advanced. So I'm interesting in common methodology (like state-machine programming style), protocol specification or library, that could simplify developing such things.

• How to adjust the distribution of values in a random data stream?

  - by BCS

  Given a infinite stream of random 0's and 1's that is from a biased (e.g. 1's are more common than 0's by a know factor) but otherwise ideal random number generator, I want to convert it into a (shorter) infinite stream that is just as ideal but also unbiased. Looking up the definition of entropy finds this graph showing how many bits of output I should, in theory, be able to get from each bit of input. The question: Is there any practical way to actually implement a converter that is nearly ideally efficient?

• Behavior is different when debugger is attached

  - by Lys

  I'm using VS 2008 to debug C# program with source code access. The expected behavior happened as long as the debugger attached to the running program, but when the program ran without debugger attached the exception threw. What are the common reasons for this to happen, and how can I tell the code difference behind this? Thanks,

• Customer count map (Google maps?)

  - by David Hamilton

  I have a two column list consisting of a US zipcode and a count (number of customers in this case). I want to put this data onto a map. Would Google maps API be a good fit for this? It seems like this would be a common enough type of problem to already have an existing (preferably Java based) solution without having to re-invent the wheel. Any suggestions?

• Dealing with whitespace in SVN?

  - by Eric the Red

  All of the SVN shops I've worked in have a strict rule - replace all tabs with spaces, to avoid whitespace conflicts and variations of tabs in different editors. Is this a very common standard? Does it really make a huge difference, and is it worth the trouble to push this standard to a group of developers new to SVN?

• Can zend's lucene implementation be configured to use a mysql database instead of the file system?

  - by soulmerge

  Is there an option for Zend's lucene implementation (or a third-party plugin) that would allow me to put the lucene dictionary into a [MySQL] database? The reason I need to ask is that the database is the only common resource for our two otherwise independent web servers.

• plain old system.out question

  I was looking at someone's code and saw that he repeatedly declared PrintStream out = System.out; and later called out.println("blah"); I actually thought this was kind of neat. Is this a common practice? Was he just being fancy?

• Web hosting a setup where both Windows and Linux are required

  - by lk

  I have a system where a website needs to be hosted on a Linux machine while a backend application that the site talks to needs to reside on Windows. Is there any "common practice" for such hosting? Note - both of the systems are mine so there is the dilemma of whether to have the machines physically located together to avoid delay for calls over the net.

• Best way to score and sum in Scala?

  - by adam77

  Is there a better way of doing this: val totalScore = set.foldLeft(0)( _ + score(_) ) or this: val totalScore = set.map(score(_)).sum I think it's quite a common operation so was expecting something sleeker like: val totalScore = set.sum( score(_) )
