• Real time updates in php for a pbbg. (Php, JavaScript, and html)

  - by Darknesschaos

  I am trying to create a PBBG (persistent browser based game) like that of OGame, Space4k, and others. My problem is with the always-updating resource collection and with the building times, as in a time is set when the building, ship, research, and etc completes building and updates the user's profile even if the user is offline. What and/or where should I learn to make this? Should it be a constantly running script in the background Note that I wish to only use PHP, HTML, CSS, JavaScript, and Mysql but will learn something new if needed. Cron jobs or the Windows equivalent seem to be the way, but it doesn't seem right or best to me.c

• The unary increment operator in pointer arithmetic

  - by RhymesWithDuck

  Hello, this is my first post. I have this function for reversing a string in C that I found. void reverse(char* c) { if (*c != 0) { reverse(c + 1); } printf("%c",*c); } It works fine but if I replace: reverse(c + 1); with: reverse(++c); the first character of the original string is truncated. My question is why would are the statements not equivalent in this instance? Thanks

• C++ / Java: Toggle boolean statement?

  - by Martijn Courteaux

  Hi, Is there a short way to toggle a boolean? With integers we can do operations like this: int i = 4; i *= 4; // equals 16 /* Which is equivalent to */ i = i * 4; So is there also something for booleans (like the *= operator for ints)? In C++: bool booleanWithAVeryLongName = true; booleanWithAVeryLongName = !booleanWithAVeryLongName; // Can it shorter? booleanWithAVeryLongName !=; // Or something? In Java: boolean booleanWithAVeryLongName = true; booleanWithAVeryLongName = !booleanWithAVeryLongName; // Can it shorter? booleanWithAVeryLongName !=; // Or something?

• run the script only once?

  - by fusion

  being new to php and coming from asp.net, i would like to know if there is an equivalent of IsPostBack, which calls a function or a method only once, once the user is logged in. i have a facebook application, in which once the user authorizes the application it should enter his details in the database. this basic stuff should have been done using the post-authorize callback url which facebook pings when the user first authorizes the app, but somehow that is not working; hence i have to do it manually. the issue is that, since i'm checking whether the user exists or not in index.php, i would not like index.php to run this code repeatedly for the same user when the user goes to the homepage every time. any ideas?

• how to represent negative number to array of integers ?

  - by stdnoit

  I must convert string of 1324312321 to array of integers in java this is fine. I could use integer parseint and string substring method but how do I repesent -12312312 to my original array of integer.. the fact that - is a char / string and convert to array of integer would alter the value ( even though I convert - to integer-equivalent , it would change the rest of 12312312) it must be an array of integers and how should I convert negative numbers and still keeep the same value somehow reminding me of two complements trick but i dont think i need to go down to binary level in my program.. any other trick for doing this? thanks!

• Is there an easy way to copy an iterator into a list in Java?

  - by Space_C0wb0y

  I want something like this: public void CopyIteratorIntoList(Iterator<Foo> fooIterator) { List<Foo> fooList = new ArrayList<Foo>(); fooList.addAll(fooIterator); } which should be equivalent to: public void CopyIteratorIntoList(Iterator<Foo> fooIterator) { List<Foo> fooList = new ArrayList<Foo>(); while(fooIterator.hasNext()) fooList.add(fooIterator.next()); } Is there any method in the API to achieve that, or is this the only way?

• Python - Create a list with initial capacity

  - by Claudiu

  Code like this often happens: l = [] while foo: #baz l.append(bar) #qux This is really slow if you're about to append thousands of elements to your list, as the list will have to constantly be re-initialized to grow. (I understand that lists aren't just wrappers around some array-type-thing, but something more complicated. I think this still applies, though; let me know if not). In Java, you can create an ArrayList with an initial capacity. If you have some idea how big your list will be, this will be a lot more efficient. I understand that code like this can often be re-factored into a list comprehension. If the for/while loop is very complicated, though, this is unfeasible. Is there any equivalent for us python programmers?

• VB.NET Use WebRequest to check if URI is valid

  - by Robbo

  Looking for the best way to determine if a URI exists in VB.NET without downloading the actual content. System.IO.FileExists/My.Computer.FileSystem.FileExists can be used locally to determine if a file exists, is there an equivalent for the Web? Currently I am using a HttpWebRequest to check URI existance using the ResponseStream. This populates the stream if the target does exist and throws an exception if it doesn't. The function is being expanded to also check for PDF files (typically 5MB +), images, etc and it will be a waste of time/bandwidth to actually populate the content into a stream. In the case of "Success" (the target does exist) I do not wish to download the file or page, simply to end up with a Boolean which indicates the whether something exists at the end of this URI.

• What is dbReferenceProperty?

  - by user246114

  Hi, In the python app engine docs, I see something called dbReferenceProperty. I can't understand what it is, or how it's used. I'm using the java interface to app engine, so I'm not sure if there's an equivalent. I'm interested in it because it sounds like some sort of pseudo-join, where we can point a property of a class to some other object's value - something like if we had: class User { private String mPhotoUrl; private String mPhone; private String mState; private String mCountry; .. etc .. } class UserLite { @ReferenceProperty User.mPhotoUrl; private String mPhotoUrl; } then if we had to update a User object's mPhotoUrl value, the change would somehow propagate out to all UserLite instances referencing it, rather than having to update every UserLite object instance manually, Thanks

• MS VC++ 6 class wizard

  - by Shane MacLaughlin

  Ok, I'm developing an application that has been in pretty much continous development over the last 16 years, from C in DOS, through various flavours of C++ and now is largely based around C++ with MFC and StingRay GUIs and various other SDKs. While I use VS 2005 for the release builds, I still use MSVC 6 for much of the GUI building, simply because ClassWizard is so much quicker in this environment than the weak equivalent tools that followed. Note that I am using ClassWizard to automatically generate code for my own user defined types (see Custom DDXs) and I like to add a lot of member variables and methods in one go. Creating them one at a time as per later versions of Visual Studio for me is a big backward step. At the same time, working with multiple IDEs is also a pain. My question is in two parts; Is there any way of getting ClassWizard to work is VS 2005 or VS 2008? Is there any drop in replacement, or alternative IDE, that provides similar levels of productivty for old C++ hacks such as myself?

• Is there a slick way to deploy my silverlight app and change settings programmatically?

  - by MIke S.

  I am fairly new to web development. I am at the point of deployment (for testing). I have a few places (maybe 4 places) where I had to add a URI that was non-relative into the appliation. So now, at deployment, those need to be changed. Is there a slick way of handling this? By slick I mean not manually going through the app and changing the URIs or a blanket find and replace (too risky). I only have 4 places to change now, but this could easily change and cause deployment issues. I am using a Microsoft technology stack. Silverlight, ASP.NET, RIA, etc. Development is done in Visual Studio 2010. I noticed that the web projects have a nifty transformation for the web.config...which is nice. Is there an equivalent mechanism for silverlight resources? Any other ways? Any thoughts?

• Does XSD allow simpleContent and complexContent at the same time?

  - by Willi Schönborn

  I want to write an xsd for the xmlrpc spec (and generate java classes out of it using jaxb). The xmlrpc spec allows values like: <value><int>123</int></value> <value><boolean>1</boolean></value> But at the same time it requires: If no type is indicated, the type is string. Which means i could receive something like this: <value>test123</value> which is equivalent to <value><string>test123</string></value> Is there a way to define this in an xsd.

• C++ Generic List Assignment

  - by S73417H

  I've clearly been stuck in Java land for too long... Is it possible to do the C++ equivalent of the following Java code: // Method List<Bar> getBars() { return new LinkedList<Bar>(); } // Assignment statement. List<Foo> stuff = getBars(); Where Foo is a sub-class of Bar. So in C++.... std::list<Bar> & getBars() { std::list<Bar> bars; return bars; } std::list<Foo> stuff = getBars(); Hope that makes sense....

• Setting enum values to 4-byte strings - why?

  - by psychotik

  I saw code similar to this in the Mac OS SDK: enum { kAudioFileStreamProperty_ReadyToProducePackets = 'redy', kAudioFileStreamProperty_FileFormat = 'ffmt', kAudioFileStreamProperty_DataFormat = 'dfmt', kAudioFileStreamProperty_FormatList = 'flst', kAudioFileStreamProperty_MagicCookieData = 'mgic', kAudioFileStreamProperty_AudioDataByteCount = 'bcnt', kAudioFileStreamProperty_AudioDataPacketCount = 'pcnt', kAudioFileStreamProperty_MaximumPacketSize = 'psze', kAudioFileStreamProperty_DataOffset = 'doff', kAudioFileStreamProperty_ChannelLayout = 'cmap', kAudioFileStreamProperty_PacketToFrame = 'pkfr', kAudioFileStreamProperty_FrameToPacket = 'frpk', kAudioFileStreamProperty_PacketToByte = 'pkby', kAudioFileStreamProperty_ByteToPacket = 'bypk', kAudioFileStreamProperty_PacketTableInfo = 'pnfo', kAudioFileStreamProperty_PacketSizeUpperBound = 'pkub', kAudioFileStreamProperty_AverageBytesPerPacket = 'abpp', kAudioFileStreamProperty_BitRate = 'brat' }; It's the first time I've seen this - I assume the compiler assigns the 32-bit integer equivalent of the strings to the enum values. I cannot think of a single good reason why this might be preferred over using simple integers. It looks hideous in a debugger (how do you tell which of these values corresponds to 1919247481?) and makes debugging just hard in general. So, is there any reason where assigning such strings to enum values actually makes sense.

• INSERT 0..n records into table 'A' based on content of table 'B' in MySql 5

  - by Robert Gowland

  Using MySql 5, I have a task where I need to update one table based on the contents of another table. For example, I need to add 'A1' to table 'A' if table 'B' contains 'B1'. I need to add 'A2a' and 'A2b' to table 'A' if table 'B' contains 'B2', etc.. In our case, the value in table 'B' we're interested is an enum. Right now I have a stored procedure containing a series of statements like: INSERT INTO A SELECT 'A1' FROM B WHERE B.Value = 'B1'; --Repeat for 'B2' -> 'A2a'; 'B2' -> 'A2b'; 'B3' -> 'A3', etc... Is there a nicer more DRY way of accomplishing this? Edit: There may be values in table 'B' that have no equivalent value for table 'A'.

• R Plot Specify number of time tickmarks

  - by Cookie

  I was wondering how I could plot more tick marks when plotting time on the x-axis. Basically, a time equivalent to pretty. Pretty obviously doesn't work so well with times, as it uses factors of 1,2,5 and 10. For time one probably wants e.g. hours, half hours, ... plot(as.POSIXct(x,origin="1960-01-01"),y,type="l",xlab="Time") gives really too few and widely spaced tickmarks. zoox<-zoo(y,as.POSIXct(stats$Time,origin="1960-01-01")) plot(zoox) gives the same. Thanks

• Rails 3 ActiveRecord group_by sort by count

  - by Craig

  The following view code generates a series of links with totals (as expected): <% @jobs.group_by(&:employer_name).sort.each do |employer, jobs| %> <%= link_to employer, jobs_path() %> <%= "(#{jobs.length})" %> <% end %> However, when I refactor the view's code and move the logic to a helper, the code doesn't work as expect. view: <%= employer_filter(@jobs_clone) %> helper: def employer_filter(jobs) jobs.group_by(&:employer_name).sort.each do |employer,jobs| link_to employer, jobs_path() end end The following output is generated: <Job:0x10342e628>#<Job:0x10342e588>#<Job:0x10342e2e0>Employer A#<Job:0x10342e1c8>Employer B#<Job:0x10342e0d8>Employer C#<Job:0x10342ded0>Employer D# What am I not understanding? At first blush, the code seems to be equivalent.

• Will I have legal issues if I attach this 'free' font using @font-face?

  - by janoChen

  *(I'm not sure if StackOverflow is the best place to ask this. But previously, I asked a similar question and it was well received).* I just found this awesome free font (Aller). It is free but it has the following written in the license file: Use by more than 25 Users, or equivalent Website Visitors, is a breach of this Free Licence Agreement, and instead requires a commercial licence. This is what I understand: If it is used in a company with more than 25 employees then it requires commercial license? If the website gets more than 25 visits per month it requires commercial license? Not sure if I got it wrong, but it doesn't make too much sense to me (specially the second statement. I want to use it in my personal portfolio were I provide web design services. Do I need a commercial license?

• NHibernate SchemaUpdate adding existing foreign keys again?

  - by afsharm

  I'm using SchemaUpdate to synchronize my hbms with existing database. Database has recently created based on hbms and is completely up-to-date. But SchemaUpdate generates all foreign key constraints again. For example suppose you have Student and Teacher. Student has association to Teacher with name ArtTeacher. ArtTeacher is a foreign key from Student to Teacher. Suppose database is up-to-date and currently holde Student, Teacher and their foreign key relation. So HBM and Database are equivalent. Know SchemaUpdate must not do anything but when I see its generated scripts, it re-produce that foreign key again. Why this happens? Is there any way to avoid it?

• When iterating over values, why does typeof(value) return "string" when value is a number? Javascrip

  - by Mark

  I'm using Google Chrome for this test: Contrary to intuition, the first loop alerts "string" 3 times, while the second loop alerts "number" 3 times. numarray = [1, 2, 3]; //for-each loop for(num in numarray) alert(typeof(num)); //standard loop for(i=0; i<numarray.length; i++) alert(typeof(numarray[i])); I was expecting both loops to alert "number" 3 times. How is the first loop implemented in Javascript? In other words, if the for-each is syntactic sugar, what is its equivalent using a standard loop? Also, is there some way to iterate over an object's namespace using a standard loop? I'm looking to touch every one of some object's methods and attributes using a loop of the second kind. I'm new to Javascript and any help is highly appreciated, thanks.

• Are there viable alternatives for Web 2.0 apps besides lots of Javascript?

  - by djembe

  If you say find C-style syntax to be in the axis of evil are you just hopelessly condemned to suck it up and deal with it if you want to provide your users with cool web 2.0 applications - for example stuff that's generally done using JQuery and Ajax etc? Are there no other choices out there? We're currently building intranet apps using pylons and a bunch of JavaScript along with a bit of Evoque. So obviously for us the world would be a better place if instead something equivalent existed written in like PythonScript. But I've yet to seen anything approaching that aside from the Android system's ASE - but obviously that's something rather unrelated. Still - if browsers could support other scripting languages....

• recommend a server side technology for gwt (beginner)

  - by user486503

  hi all ! I am developing a gwt project and am looking for an appropriate server side technology. it should support be open source and support user login (and not using openID...) with password recovery etc it seems that the de-facto standard would be spring + hibernate. however, I am unfamiliar with neither of them and understand that the learning curve (especially for spring) is very high. gwt was quite easy to learn using GOOG's excellent online tutorials but the spring equivalent seem to impose lots of configuration files and deeper understanding of its internals. so I am looking for a simpler server side technology to deploy my gwt app. I am definitely prepared to learn a new framework if necessary but not something that would take me 2 months just to understand the fundamentals... any ideas...?

• Best practices for packaging resources (jpg's, sound, video) in an iPhone app?

  - by Mel

  I'm a newb iPhone developer writing an app that has several large JPGs and sound files. Everything works ok if I drag these non-code resources into my project. But I am wondering if this is the right way to package my app. In Windows development, I would create a "resource DLL" that keeps the .exe size small. What is the equivalent for iPhone? I think I should be creating a "bundle" - can someone please give me some pointers to using these and how to link them into my main project? Thanks!

• html - how do I make a page load in a new tab in IE8?

  - by erynion

  My website works in Firefox - pages on the site load in the current tab, and links off site load a new tab. IE8 won't behave: target="_blank" opens a whole new window; the other options, _self _top _parent, all open the page in the current tab. I have Firefox set to "Open new windows in a new tab." The links to pages on my site all have target="_self" and Firefox keeps these in the current tab. On the external links I don't have a target set (I added _blank to see if it fixed IE8, and doing that didn't affect Firefox). I can't find an equivalent setting in IE8. Tools-Internet Options-General-Tabs/Settings has an enable tabs box, and a sub-option to automatically switch to newly opened tabs. Is there some html that will work? An IE8 setting I'm missing? Any help appreciated.

• String loops in Python

  - by Steve Hunter

  I have two pools of strings and I would like to do a loop over both. For example, if I want to put two labeled apples in one plate I'll write: basket1 = ['apple#1', 'apple#2', 'apple#3', 'apple#4'] for fruit1 in basket1: basket2 = ['apple#1', 'apple#2', 'apple#3', 'apple#4'] for fruit2 in basket2: if fruit1 == fruit2: print 'Oops!' else: print "New Plate = %s and %s" % (fruit1, fruit2) However, I don't want order to matter -- for example I am considering apple#1-apple#2 equivalent to apple#2-apple#1. What's the easiest way to code this? I'm thinking about making a counter in the second loop to track the second basket and not starting from the point-zero in the second loop every time.
