  • search engine crawling frequency

    - by Aditya Pratap Singh
    I want to design a search engine for news websites ie. download various article pages from these websites, index the pages, and answer search queries on the index. I want a short pseudocode to find an appropriate crawling frequency -- i do not want to crawl too often because the website may not have changed, and do not want to crawl too infrequently because index would then be out of date. Assume that crawling code looks as follows while(1) { sleep(sleep_interval); // sleep for sleep_interval crawl(website); // crawls the entire website diff = diff(currently_crawled_website, previously_crawled_website); // returns a % value of difference between the latest and previous crawls of the website sleep_interval = infer_sleep_interval(diff, sleep_interval); } looking for a pseudocode for the infer_sleep_interval method: long sleep_interval infer_sleep_interval(int diff_percentage,long previous_sleep_interval) { ... ... ... } i want to design method which adaptively alters the sleeping interval based on the update frequency of the website.

  • Objects do not retain the frame that I give then when using CGAffineTransforms with Core Animation

    - by user170030
    Hi, I'm making a game where when a card is touched, it grows so that it is focused, and when you 'let go', it goes back to its original size and place. This seems pretty standard, however, when I add cards and move the hand around to accommodate different numbers of cards, touching the card makes it go to its original place, and not to the new place. This has been stumping me for a while now Any hints would be much appreciated. Thanks !

  • What can I do to improve a project if there is a no-listening situation. Developers vs Management

    - by NazGul
    Hi all, I hope that I'm not the only one and I can get a answer from someone with more experience than me, so I can think cleaner and I don't get depressed with this developer's life. I'm working as developer for a small company three years now. In that three years I'm working in the same project and sincerely, I think this project could be used as a CASE STUDY because it has all the situations that cannot happen in a project and that makes a project fails. To begin with, and I believe you've already noticed, the project has 3 years already (develoment only) and is still unfinished, because in every meeting there is a "new priority" ,or a "new problem" to be solve or a "new feature" to be add. So, first problem is no target set. How can you know when something is finished if you don't know what you want? I understand Management, because they see an oportunity and try to get that, but I don't understand how can they not see (or hear us) that they'll lose all they already have and what they'll eventually get. Second, there is no team group. My team consists of three people, a Senior Developer, a DBA and, finally, I for all the work (support, testing, new features, bug fixing, meeting, projet management of clients, etc) aka Junior Developer. The first (senior developer), does not perform any tests on his changes, so, most of the time, his changes give us problems (us = me, since I'm the one who will fix it). The second (DBA) is an uncompromising person and you can not talk to him, believe me, I tried! In his view, everything he does is fantastic... even if it is the most complicated to make it... And he does everything he wants, even if we need that only for 5 months later and would help some extra-hand to do the things we have to do for now. As you can see, there is very hard to work with no help... Third, there is no testings. Every... I repeat, Every release of the project, the customers wants to kill us, because there is a lot of bugs. Management? They say that they want tests before the release. Us? We say the same. Time? No time. Management? There is always some time to open the application and click in some buttons. Us? Try to explain that it is not so simple. Management doesn't care... end of story. Actually, must of the bugs could be avoid with a rigorous work... Some people just want to do the show to the Management. "Did you ask for this? Cool, it's done. Bugs? The Do-all-the-work guy will solve." Unfortunally for me, sometimes the Do-all-the-work also has to finish it. And to makes this all better, I'm the person who will listen the complaints from the customers. Cool, huh? I know, everyone makes mistakes. But there is mistakes and mistakes... To complete, in the Management view, "the problem is the lack of an individual project management", because we cannot do all the stuff they ask, even if there is no PM for the project itself. And ask us to work overtime without any reward... I do say all this stuff to the management and others members, but by telling this, the I'm the bad guy, the guy who is complain when everything is going well... but we need to work overtime... sigh What can I do to make it works? Anyone has a situation like this, what did you do? I hope you could understand my problem, my English is a little rusty. Thanks.

  • Touching an object in a tweened animation?

    - by Michael
    I'm having trouble porting a simple game I developed for the iPhone over to Android. The game has an animated ball which moves from Point A to Point B. The user must touch the ball before it reaches point B or lose the game. This was easy to implement on the iPhone using Core Animation since I could locate the current position of the ball by accessing its animation layer. In Android, I attempted to recreate the game using tweened animation and represented the ball as a Drawable. My issue is that I can't determine if the user is touching the spot because the Drawable apparently bounds do not update as the ball visually moves - making the program think the ball is always in its original position. While searching these forums I saw an Android team dev. confirm that you can't get the current location in a tweened animation but offered no solution for a workaround. Can I accomplish this on the Android using my current approach? If not, what approach should I use? Best regards, Michael

  • Does ASP.net 1.1 support Generic HttpHandlers ?

    - by Campos
    I need to get an image from a SQL Server as a byte[], and load it to a WebControl.Image. The only seemingly good way to do it that I found is to implement IHttpHandler and handle the request accordingly. But I'm stuck to using asp.net 1.1. Does it support ashx files?

  • Showing a loading spinner only if the data has not been cached.

    - by Aaron Mc Adam
    Hi guys, Currently, my code shows a loading spinner gif, returns the data and caches it. However, once the data has been cached, there is a flicker of the loading gif for a split second before the data gets loaded in. It's distracting and I'd like to get rid of it. I think I'm using the wrong method in the beforeSend function here: $.ajax({ type : "GET", cache : false, url : "book_data.php", data : { keywords : keywords, page : page }, beforeSend : function() { $('.jPag-pages li:not(.cached)').each(function (i) { $('#searchResults').html('<p id="loader">Loading...<img src="../assets/images/ajax-loader.gif" alt="Loading..." /></p>'); }); }, success : function(data) { $('.jPag-current').parent().addClass('cached'); $('#searchResults').replaceWith($(data).find('#searchResults')).find('table.sortable tbody tr:odd').addClass('odd'); detailPage(); selectForm(); } });

  • Practical programming test in interview

    - by redspike
    I have been invited to do a second interview for a company recruiting for a software engineer. This interview will consist of a 45 minute programmatic test on a laptop followed by a whiteboard presentation on the solution. This position is Java/J2EE based so I'm assuming (hoping) the test will be implemented using Java. Have you ever done anything like this? What was the nature of the problem you had to solve? What is a good way to prepare for this type of interview?

  • What side project/research should be chosen to increase my Marketability

    - by CheesePls
    I am a Junior CS Major at a Javaschool and I find myself having an easy time and thought there may be some good project or a language to learn or research in this newfound free time. What would you recommend so as to increase my ability to find a good job(somewhere that allows for continuous learning and treats its programmers well)after college? My thoughts were learning Scheme, making a working Zelda-like game(the original), find some open source project to help with.

  • License similar to the MIT license but without the ability to sell?

    - by Ben
    I'm trying to decide how I want to license my Wordpress themes to the public. I know that the GPL is recommended to Wordpress theme creators, however I feel it might not be liberal enough for me because I want businesses to be able to use them if they want to. I really like the MIT license, the only thing that gets me is the freedom to sell part. I don't want someone taking my themes and selling them on some theme farm site, they should be free for everyone, however I don't want to require them to republish any changes under the MIT as well, I think that that freedom should remain intact. Is there a license that sort of fits into the terms I specified here? I'm not a lawyer so I have trouble reading through the complicated language of licenses. If there is not a similar license to the MIT but with the terms I have specified, should I just license under a modified MIT? If so, can anyone help me write it? Thanks very much!

  • Difference between two commands of fetching Shopping Cart Items in Magento

    - by Knowledge Craving
    In Magento, if you need to get / fetch the Shopping Cart's Item details, you can do it in any of the two possible ways, which will provide you with all the shopped Items in an array:- $cartItems1 = $cart->getQuote()->getAllItems(); $cartItems2 = $cart->getItems()->getData(); But before using any one of the above two methods, you need to initialize the shopping cart object as:- $cart = new Mage_Checkout_Model_Cart(); $cart->init(); Can anyone please describe in details as to what the two options provide & their differences between each other, along with their possible usage. In any more such option is available in Magento, can anyone please highlight it?

  • Increased kerning on website text

    - by Bradley Herman
    We're developing a site for a client right now and my boss (designer only) is once again making me increase letter-spacing on the text so that it looks 'prettier'. I am of the firm belief that this often causes eye-strain and hinders readability in body copy, but being the boss, she is of course always 'right' until I can provide her with examples showing why she's wrong (generally pretty easy). In this case, however, I can't find any articles talking about eye-strain and kerning, so I figured I'd ask what you guys think about the issue of increased letter-spacing in web text. Take a look at http://sparktoignite.com/allograft/process.php and tell me how you feel about the body copy. We're using font-embedding, so you'll only see the proper font in FF, Safari, and Chrome. Let me know what you guys think about the readability and eye-strain caused by the font. My boss currently thinks it's 100% perfect (she wanted the kerning increased further, but I talked her down luckily).

  • How does this Singleton Web Class persists session data, even though session is not updated in the p

    - by Micah Burnett
    Ok, I've got this singleton-like web class which uses session to maintain state. I initially thought I was going to have to manipulate the session variables on each "set" so that the new values were updated in the session. However I tried using it as-is, and somehow, it remembers state. For example, if run this code on one page: UserContext.Current.User.FirstName = "Micah"; And run this code in a different browser tab, FirstName is displayed correctly: Response.Write(UserContext.Current.User.FirstName); Can someone tell me (prove) how this data is getting persisted in the session? Here is the class: using System; using System.Collections.Generic; using System.Linq; using System.Web; public class UserContext { private UserContext() { } public static UserContext Current { get { if (System.Web.HttpContext.Current.Session["UserContext"] == null) { UserContext uc = new UserContext(); uc.User = new User(); System.Web.HttpContext.Current.Session["UserContext"] = uc; } return (UserContext)System.Web.HttpContext.Current.Session["UserContext"]; } } private string HospitalField; public string Hospital { get { return HospitalField; } set { HospitalField = value; ContractField = null; ModelType = null; } } private string ContractField; public string Contract { get { return ContractField; } set { ContractField = value; ModelType = string.Empty; } } private string ModelTypeField; public string ModelType { get { return ModelTypeField; } set { ModelTypeField = value; } } private User UserField; public User User { get { return UserField; } set { UserField = value; } } public void DoSomething() { } } public class User { public int UserId { get; set; } public string FirstName { get; set; } }

  • Where does C# and the .NET Framework fail?

    - by Nate Bross
    In my non-programming life, I always attempt to use the approprite tool for the job, and I feel that I do the same in my programming life, but I find that I am choosing C# and .NET for almost everything. I'm finding it hard to come up with (realistic business) needs that cannot be met by .NET and C#. Obviously embedded systems might require something less bloated than the .NET Micro Framework, but I'm really looking for line of business type situations where .NET is not the best tool. I'm primarly a C# and .NET guy since its what I'm the most comfertable in, but I know a fair amount of C++, php, VB, powershell, batch files, and Java, as well as being versed in the web technologes (javascript, html/css). But I'm open minded about it my skill set and I'm looking for cases where C# and .NET are not the right tool for the job. The bottom line here, is that I feel that I'm choosing C# and .NET simply because I am very comfertable with it, so I'm looking for cases where you have chosen something other than .NET, even though you are primarly a .NET developer.

  • Develop applications to mobiles

    - by muek
    Hi there, I have very easy question, but I simply have any idea of the answer. I have developed a small mobile-application using java, for my nokia. The problem is that when installed on my samsung the application simply crashed. Then I tried on my other nokia but different model, and I didn't got the normal behavior. So my question is, does anyone have any idea how companies that develop mobiles applications/games test their software. Does they have to have all models for all mobiles phones??

  • Repeating parallax using Cocos2D on Android

    - by Saurabh Verma
    I want to draw a infinitely repeating parallax using Cocos2D on Android. Now, there are some solutions given to this problem in Objective C, but I'm stuck with my implementation in Android. I have tried using CCSprite background = CCSprite.sprite("background_island.png"); CCTexParams params = new CCTexParams(GL10.GL_LINEAR,GL10.GL_LINEAR,GL10.GL_REPEAT,GL10.GL_REPEAT); background.getTexture().setTexParameters(params); But it only extends the background in 1 direction. I guess I have to use 2 sprites, such that as soon as 1st finishes, the other starts and vice versa, but I'm stuck with the implementation.

  • jQuery Cluetip not activated until after hover or click event

    - by kenny99
    I'm not sure what is causing this, but I am using cluetip and binding it to a live event (either click or mouseenter), but in each situation the cluetip isn't firing until after one click or hover event. I am using the live event for ajax loaded content, but I'm also having this issue with non-Ajax loaded content. I'm not sure why this is happening - can anyone see where I might be going wrong? Many thanks. $("a.jTip").live("click", function(){ $('a.jTip').cluetip({ attribute: 'href', cluetipClass: 'jtip', arrows: true, activation: 'click', ajaxCache: false, dropShadow: true, sticky: true, mouseOutClose: false, closePosition: 'title' }) return false; });

  • Storing script files outside web root

    - by memilanuk
    I've seen recommendations to store some or all php include files some place other than in the web document root directory (username/public_html in my case) for the specific reason of protecting php files with sensitive information (like database connection and login info) in the event that the web server hiccups and stops protecting php files and they become 'visible' to outsiders who know where to look. It seems somewhat paranoid to me, but I'm guessing people have gotten burned badly on this before so I'm willing to go along. The suggestion usually takes the form of having the include files in something like '../include_files/' so its not directly in the document root and not directly accessible to outsiders through the web server. My question is this: is there a significant difference in security between that way and just putting your 'include_files' directory under the document root and sticking an .htaccess file in there (with the appropriate entries)? Would putting an .htaccess file in '../include_files/' make any significant improvement there? TIA, Monte

    - by Roeland
    Hey guys, I am trying to create a grid like system with div's with content floated left. The problem is that the height of each div is not static since the content is different in each one. Since the height is different.. things get outta whack if one is taller then another in one row. Is there some sort of css way or js (prefer javascript) way to get around this. I really want to avoid setting large heights on the divs to get them to line up. You can see the example here: http://www.foreclosurejournalinc.com/index.php?option=com_hotproperty&view=type&id=1

  • Webfaction apache + mod_wsgi + django configuration issue

    - by Dmitry Guyvoronsky
    A problem that I stumbled upon recently, and, even though I solved it, I would like to hear your opinion of what correct/simple/adopted solution would be. I'm developing website using Django + python. When I run it on local machine with "python manage.py runserver", local address is http://127.0.0.1:8000/ by default. However, on production server my app has other url, with path - like "http://server.name/myproj/" I need to generate and use permanent urls. If I'm using {% url view params %}, I'm getting paths that are relative to / , since my urls.py contains this urlpatterns = patterns('', (r'^(\d+)?$', 'myproj.myapp.views.index'), (r'^img/(.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT + '/img' }), (r'^css/(.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT + '/css' }), ) So far, I see 2 solutions: modify urls.py, include '/myproj/' in case of production run use request.build_absolute_uri() for creating link in views.py or pass some variable with 'hostname:port/path' in templates Are there prettier ways to deal with this problem? Thank you. Update: Well, the problem seems to be not in django, but in webfaction way to configure wsgi. Apache configuration for application with URL "hostname.com/myapp" contains the following line WSGIScriptAlias / /home/dreamiurg/webapps/pinfont/myproject.wsgi So, SCRIPT_NAME is empty, and the only solution I see is to get to mod_python or serve my application from root. Any ideas?
