• Programming language for fast calculations with big integers

  - by sub

  I'm doing Project Euler problems at the moment and I can solve most of them using my own programming language which uses direct C++ integers (so they are bound to 2^32 on my machine). However, at times there are problems which require me to work with very high numbers, I can't do that with native integers. So I implemented a BigInt library in my language which unfortunately gets extremely slow at times. Is there a programming language suitable for very efficient handling of big numbers? I mean that I want to do the things I could do in other programming languages with it (variables, loops, etc.), but in a faster way. If you have got tips for workarounds of the 2^32 limit in my language/C++/other languages, please tell me too!

• Activity should be transparent, but has black background

  - by Uwe Krass

  I followed the instructions of writing a transparent layout. My res/values/style.xml looks like this: <resources> <style name="Theme" parent="android:Theme" /> <style name="Theme.Transparent"> <item name="android:windowBackground">@drawable/transparent_background</item> </style> <drawable name="transparent_background">#00000000</drawable> </resources> The activity snippet looks like this: <activity android:name=".Controlls" android:label="Controlls" android:theme="@style/Theme.Transparent"> When I start this activity from my root activity, the layout gets drawn correctly, but the background stays black.

• border highlighting loop with jquery

  - by Tek

  I'm having trouble coming up with a loop that changes the border color of an image from black to yellow and yellow to black over x seconds. Then applying an interrupt to the loop when the image gets clicked on. I don't know where to start, can someone point me in the right direction? I think I may be using the wrong tools to properly write this. Here's what I've come up so far, though if there's a better way to write this, do share! for( i = 100; i >= 0; i--) { $("#imgid").css("border-color", 'rgb(' + i + '%,' + i + '%,0)'); } I'm having trouble picturing how I could combine two loops so that I can also count upwards as well so that it will turn into yellow and back to black. I also don't know how to go about controlling the amount of time it takes for that loop to execute and creating an interrupt when #imigid is clicked. Which is where I'm not sure how to write.

• subversion 1.6.x losing changes on check-in

  - by Bernard

  I'm trying to figure out if this is a known issue with SVN 1.6.x Developer A modifies a file and commits it. Developer B modifies the same file. Tries to commit it and gets told local copy out of date so does an update and then a commit. However the changes from Developer A are lost so the resulting file only contains the version that Developer B checked in. We can see this in the logs. It seems to happen when the same file is modified but in different places. Anyone else experienced this? We've had it happen 4 or 5 times in the past few weeks and we've lost a half day or so each time trying to figure out what's been lost, etc. We're starting to lose confidence in SVN. Should we be thinking of moving to GIT or Mecurial? Would that sort out this problem?

• Inject a EJB into a JSF converter with JEE6

  - by Michael Bavin

  Hi, I have a stateless EJB that acceses my database. I need this bean in a JSF 2 converter to retreive an entity object from the String value parameter. I'm using JEE6 with Glassfish V3 @EJB annotation does not work and gets a NPE, because it's in the faces context and it has not access to the ejb context. My question is: Is it still possible to Inject this bean (With a @Resource or other annotation, a JNDI lookup,...), or do i need a workaround? Thank you Solution Do a JNDI lookup like this: try { ic = new InitialContext(); myejb= (MyEJB) ic .lookup("java:global/xxxx/MyEJB"); } catch (NamingException e) { e.printStackTrace(); }

• alias some columns names as one field in oracle's join select query

  - by Marecky

  Hi We are developing something like a social networking website. I've got task to do 'follow me' functionality. In our website objects are users, teams, companies, channels and groups (please don't ask why there are groups and teams - it is complicated for me too, but teams are releated to user's talent) Users, teams, channels, companies and groups have all their own tables. I have a query which gets me all the follower's leaders like this select --fo.leader_id, --fo.leader_type, us.name as user_name, co.name as company_name, ch.title as channel_name, gr.name as group_name, tt.name as team_name from follow_up fo left join users us on (fo.leader_id = us.id and fo.leader_type = 'user') left join companies co on (fo.leader_id = co.user_id and fo.leader_type = 'company') left join channels ch on (fo.leader_id = ch.id and fo.leader_type = 'channel') left join groups gr on (fo.leader_id = gr.id and fo.leader_type = 'group') left join talent_teams tt on (fo.leader_id = tt.id and fo.leader_type = 'team') where follower_id = 83 I need to get all fields like: user_name, company_name, channel_name, group_name, team_name as one field in SELECT's product. I have tried to alias them all the same 'name' but Oracle numbered it. Please help :)

• What approaches are available to revert an IDirect3DDevice9 instance to its default render state?

  - by Rafael Goodman

  Given an instance of IDirect3DDevice9, what approaches are available to put it in its original render state (i.e. the state it was in when the device was initially created)? The cleanest way that I've come across is to create a state block via IDirect3DDevice9::CreateStateBlock just after the device has been created so that it can be applied later. Unfortunately, I'm operating under the constraints of an existing project such that I can't modify the device creation code; by the time my component gets the device, its default state has been modified. As a result, I'm looking for alternative approaches. Thx! ~Raf

• jKey (JavaScript key shortcut plugin) Issue

  - by Oscar Godson

  Me and a friend are writing a plugin for jQuery that makes it easy for devs to add key shortcuts and we're damn close but no cigar. We're having issues with the key combos. It seems like we are having issues when you call the same selector multiple times on a page. Try pressing alt+a... youll see it works one time, then gets all mangled up. Anyone know how to fix it? It'll be on github after it's corrected and I'd be happy to add "thank you to" link to whoever can fix this in the header with the copyright info :) It's nicely documented and i have all the code and stuff here. So... anyone? http://jsbin.com/azaha4

• GWT Strength compared to other framework??

  - by Noor

  One of the main strength of GWT is to code in java and everything gets compiled and is loaded by several browsers through gwt deferred binding?? Apart from this, i.e. working only on a single code base, do GWT has any other advantage compared to other existing framework?? Edit: I'm trying to say why should we use gwt and not another framework?? What is there in GWT that makes it special for web application development?? What GWT makes for us and another framework or toolkit don't do?? As i said above GWT makes deferred binding which is a plus, so I wanted what other things it do that makes it special and unique??

• Circular dock/menu in css or jquery

  - by sasidhar

  Is it possible to have a circular menu or dock using css or jquery.? I have a set of images as the dock items that need to be displayed as a circular dock... however the number of items in the dock are not constant and may vary.... so i cannot tend to use constant values for positioning each item in a pre-defined manner. Ajax loads some images into this particular div and i need to use css or jquery to style this so that they get displayed as circular dock items. Any idea on how this can be implemented..? I would like a browser in-specific implementation, but i also welcome if some one has some solutions specific to few browsers... UPDATE I don't think i exactly want a pie menu... it easily gets messed up as the number of dock items increase. I am looking for a spiral dock. and by spiral i mean that the menu items must be in the following alignment..

• Python metaprogramming help

  - by Timmy

  im looking into mongoengine, and i wanted to make a class an "EmbeddedDocument" dynamically, so i do this def custom(cls): cls = type( cls.__name__, (EmbeddedDocument,), cls.__dict__.copy() ) cls.a = FloatField(required=True) cls.b = FloatField(required=True) return cls A = custom( A ) and tried it on some classes, but its not doing some of the base class's init or sumthing in BaseDocument def __init__(self, **values): self._data = {} # Assign initial values to instance for attr_name, attr_value in self._fields.items(): if attr_name in values: setattr(self, attr_name, values.pop(attr_name)) else: # Use default value if present value = getattr(self, attr_name, None) setattr(self, attr_name, value) but this never gets used, thus never setting ._data, and giving me errors. how do i do this?

• Dynamically reducing image dimension as well as image size in C#

  - by hanesjw

  I have an image gallery that is created using a repeater control. The repeater gets bound inside my code behind file to a table that contains various image paths. The images in my repeater are populated like this <img src='<%# Eval("PicturePath")' %>' height='200px' width='150px'/> (or something along those lines, I don't recall the exact syntax) The problem is sometimes the images themselves are massive so the load times are a little ridiculous. And populating a 150x200px image definitely should not require a 3MB file. Is there a way I can not only change the image dimensions, but shrink the file size down as well? Thanks!

• GridView and multiple postbacks problem

  - by Jonn

  I have a grid view containing checkboxes and a great deal of problems surrounding it. First of all the page on_load and on_init gets called twice. The first call says it's a postback and the second isn't. If I check for postbacks, during the second call the change of state (i.e. A button_click event that was supposed to refresh the data in the grid) that triggered during the first call does not register. If I don't check for postbacks, checkboxes in the GridView do not retain its state by the second call to OnLoad/OnInit.

• Why is display:inline killing IE 8.0 performance?

  - by monstermensch

  I have an image gallery based on this jQuery plugin: http://jqueryfordesigners.com/demo/slider-gallery.html This works really well in Firefox, Chrome and even IE 7.0, but when I try it with more than 50 images in IE 8.0 the performance is incredible slow. Just hovering over the thumbnail brings the CPU load to 100%. At first I thought it's a Javascript problem, so I used the IE profiler, but the results were normal. Next I checked the CSS and finally found the cause: .sliderGallery UL LI { display: inline; } This gets the thumbnails to align horizontally. If I chance it to display:block, performance is fine and the scroller is still working but obviously it looks funny, because the thumbs are aligned vertically. My questions: Why does IE 8 have this problem with many display:inline elements What can I do to solve it I'll gladly provide more information if necessary.

• a completely decoupled OO system ?

  - by shrini1000

  To make an OO system as decoupled as possible, I'm thinking of the following approach: 1) we run an RMI/directory like service where objects can register and discover each other. They talk to this service through an interface 2) we run a messaging service to which objects can publish messages, and register subscription callbacks. Again, this happens through interfaces 3) when object A wants to invoke a method on object B, it discovers the target object's unique identity through #1 above, and publishes a message on the message service for object B 4) message services invokes B's callback to give it the message 5) B processes the request and sends the response for A on message service 6) A's callback is called and it gets the response. I feel this system is as decoupled as practically possible, but it has the following problems: 1) communication is typically asynchronous 2) hence it's non real time 3) the system as a whole is less efficient. Are there any other practical problems where this design obviously won't be applicable ? What are your thoughts on this design in general ?

• handling activity destruction in multithreaded android app

  - by Jayesh

  Hi, I have a multithreded app where background threads are used to load data over network or from disk/db. Every once in a while user will perform some action e.g. fetch news over network, which will spawn a background AsyncTask, but for some reason user will quit the app (press back button so that activity gets destroyed). In most such scenarios, I make appropriate checks in the background thread after it returns from n/w i/o, so that it won't crash by accessing members of the activity that is destroyed by now. However some corner cases are left where crashes happen, because the background thread would access some member of activity that is now null. Do other Android developers have some generic/recommended framework to handle such scenarios? These are the times when I wish android would have guaranteed termination of all threads when activity destroys (in the same way that regular linux process cleans up when it's quit)... but I guess Android devs had good reasons for not exposing process lifetimes through the api.

• How Does a Login system generally work with OOP?

  - by fakingfantastic

  Sorry if this is a badly formed question, but I'm trying to make my web applications (using PHP) more OO. *EDIT* I'm developing the Framework myself */EDIT* Everything is great so far, I've made a Front Controller system that taps into a MVC system. The FC figures out what page you want, loads the specific page Controller (*EDIT* which extends an abstract Controller Object */EDIT*), which gets anything it needs from Models, and then calls the appropriate View. Very basic. But now, I need to make an admin section (quasi-CMS). How does a login system fit into the grand scheme of things? Do you set controllers as needing a login? If so, how? What If you only want certain views of a controller requiring login? Thanks in advance.

• Creating a PHP call home "time bomb" to protect my interests

  - by RC

  Hi everyone, I produced a PHP web app for a client some months back that is hosted on their own server. I have still not been paid for this work, and they are giving me the runaround. It turns out that I still have remote admin access to their server, so I can make code changes. What I was thinking of doing was to move the core kernel off-site onto one of my own servers, and program in some kind of callback or include that gets the kernel (critical functions) from my server. Give it two weeks or so for their backups to catch this change, and then pull the plug and exercise leverage. If I do this, they will pay immediately, because the site is a critical one for a very large and influential client of theirs. What is the most effective and easiest way of doing this? What code do I use? Thanks for any pointers.

• Error safe/correcting resource identifier

  - by Martin

  The receiver is my website, the sender is the same but the medium is noisy, a user. He will read an alphanumeric code of length 6 and later input the same code to identify a resource. A good use for a error correcting code, I thought, and rather than do the research I thought I'd just put the question out there. Or I might be going about it the wrong way, since the situation is rather like sending a perfect dictionary along with every transmission. The requirements on the code are simply: 6 alphanumeric digits, to start with until I run out, anyway. If the user gets it wrong I should still be able to identify the right resource. No resource is preferable to the wrong one. Easy to code or have free libraries for .net Any suggestions?

• can Yahoo and Hotmail contacts api be used without leaving the site?

  - by Dr.Dredel

  I might be missing something but I'm trying to implement a contacts retrieval mechanism akin to the one that is offered by Google for Yahoo and Hotmail. Both APIs seem to require the user to actually go to their sites to log in. The documentation is really convoluted for both. I was hoping someone has done this and can point me to a simple way (if there is one) to allow the user to log in directly in my app and then for me to go and fetch their contacts for them (preferably in XML, but JSON would also do nicely). I currently have a Perl script that goes and gets the gmail stuff and works very nicely. I was (maybe wildly optimistically) hoping that Yahoo and Microsoft would have similarly useful mechanisms.

• RESTful application validation. Mix of frontend/backend validation. How?

  - by Julian Davchev

  Hi. Using RESTful for all backend persistance and operations. I just pass data from frontend (by frontend I don't mean clientside but the part that is making use of the REST) to rest and data gets back success or no with validation errors if any. Thing is I have stuff that should be validated on frontend too..like csrf tokens, captcha etc. Only reasonable way is I mix validation coming from token/captcha checks and validation errors coming back from REST. Issue with this will be kinda automation as I wouldn't want form field names to map 1:1 with backend field names use by the REST documents. Any pointers ideas are more than welcome.

• Autorelease with elements in a UITableViewCell - memory leak

  - by Shaun Budhram

  In my 'cellForRowAtIndexPath' method for a UITableView delegate, I'm allocating a cell if it doesn't exist, and in this cell, I'm creating a new activity spinner like so: UIActivityIndicatorView *actView = [[[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray ] autorelease]; I'm using Leaks to detect memory leaks in my program, and for some reason, this is coming up as a leak, even though it's autoreleasing. The cell itself is also autoreleasing. Has anyone had experience with autoreleasing variables coming up as leaks in the Leaks instrument, and how to tackle these problems? Also, if it helps, this is the history Leaks is displaying for this memory location. It looks like it at some point gets an additional retain message? This is not being done in my code.
