• Looking for a specific kind of WEB framework, no malarkey please

  - by Hello you all men

  We do maintenence on a number of systems. I'm finally in a place where I'm teh fucking boss for once, and have to design a large system that will have a long maintenance contract. There's a couple of tasks I find myself always repeating: 1) similar tasks for users with JS and those without 2) similar things for contents and rss/atom feeds, etc. To combat these I will need appropriate handling of assets (think JS files, CSS, themes/templates, etc.), excellent auth/user systems, javascript/ajax forethought, appropriate model setups. Codeigniter fails on many of these. Basically, with enough time I could build this system with Zend, but I'm curious what else is out there as Zend is also kind of a heavy-weight. We need something that is Rapid but maintainable, CodeIgniter is not maintainable. We will have a lot of AJAX APIs in place for the design team to play with. At first I thought jQuery was cool, but now I'm looking at Dojo.

• how to generate a random string, and specify the length you want, or better generate unique string on specification you want

  - by HCP

  There is a library to generate Random numbers, so why in't there a library for generation random strings ? In other words how to generate a random string, and specify the length you want, or better generate unique string on specification you want i.e specify the length, a unique string within my application is enough for me. I know I can create a Guid (globally unique identifier) but those are quite long, longer they need to be. int length = 8; string s = RandomString.NextRandomString(length) uniquestringCollection = new UniquestringsCollection(length) string s2 = uniquestringCollection.GetNext();

• Datagrid row height doesnot shrink back

  - by prince23

  Hi, I have a data grid, in each row I have one cell which needs to have a very lengthy text which is about 1000 characters long. So I decided to put the text in the expander control keeping the cell width fixed, when the user wants to read the text, he clicks on the expander to open and reads it. The row height automatically grows when the expander is expanded but when the expander is collapsed back, the row height doesnt shirk. Can anyone pls tell me how to set the row height back after the expander is collapsed? i tried the follwing link. http://forums.silverlight.net/forums/p/133177/299186.aspx#299186 but this did not work any help would be grealty appreciated, thanks

• Fastest way for inserting very large number of records into a Table in SQL

  - by Irchi

  The problem is, we have a huge number of records (more than a million) to be inserted into a single table from a Java application. The records are created by the Java code, it's not a move from another table, so INSERT/SELECT won't help. Currently, my bottleneck is the INSERT statements. I'm using PreparedStatement to speed-up the process, but I can't get more than 50 recods per second on a normal server. The table is not complicated at all, and there are no indexes defined on it. The process takes too long, and the time it takes will make problems. What can I do to get the maximum speed (INSERT per second) possible? Database: MS SQL 2008. Application: Java-based, using Microsoft JDBC driver.

• Best way to notify several java applets/applications of a change on a server

  - by Dustin

  I need to know the best (fastest) way to have a server (preferably a php based one, but a jsp/servlet one could be set up as well using google app engine) notify several java applets/applications that a change has occurred to the data. The way i am picturing this to work will be very similar to that of the way i think an online java game (like Runescape) works User 1: Changes data on server. Server: returns success to User 1, notifies connected computers of change. Connected Computer 1: processes change, returns success to server. Connected Computer 2: processes change, returns success to server. Connected Computer 3: processes change, returns success to server. Connected Computer 4: processes change, returns success to server. I am hoping to have this entire process complete in half a second, and not involve polling as there will be long durations of nothing, followed by a sudden moment where 4 events happen in succession.

• Which character is first among 4 characters in c++

  - by Ashiqur Rahman

  In my project I take a string from user and then I need to check if vowels a, e, I, O, U are present. If so, I have to find out which one comes first in the string and which one comes next after that. For example, if a user gave input something like this: char expr[] = "this is for something real"; I comes first, then I again, then O and so on. I checked whether the characters are in the string or not using strchr(expr,'character here'). To find which character comes first, I find the index of each character using const char *ptr = strchr(expr, characters here); if(ptr) { int index = ptr - expr; } After that I check which index is bigger. But this is very long process. Is there a smarter way to do this?

• 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....

• Joomla 2.5 disable and remove Smart Cache

  - by WooDzu

  I am maintaining a Joomla 2.5 based magazine website with 3-4 new, long articles every day. Smart Search was enabled by default and now I've got a few "finder" tables full of indexed phrases and therms. I wonder if there are any disadvantages if I'd: Disable the Smart Search plugin Remove these 'finder' tables completely Aha, we're using a Search field, which works fine, but I'm not sure what's going to happen if I disable the plugin and remove these tables. Will it then search for phrases in content Joomla tables or simply break w/o missing 'finder' tables Has anyone tried this before?

• Are there any well-known algorithms or computer models that computer scientists use to predict FIFA

  - by Khnle

  Occasionally I read news articles that mention about some computer models that computer scientists use to predict winners of some sporting events or the odds for betting which I think there must be a mathematical model behind it. I never bothered to think twice even though I am a "pseudo computer scientist" myself. With the 2010 FIFA World Cup just underway, and since I am also a "pseudo football/soccer player" myself, I just started to wonder about these calculations algorithms. For example, I know one factor is determining the strength of opponents, so that a win against a strong opponent can count more than a win against a weak opponent. But it now kind of gets in a circular loop, or at least how does one determine the strength of a team in the first place, before that team can be considered strong or weak? If it's based on a historical data then there's no way that could be accurate, because those players of the past are no longer on the fields so their impact is none (except maybe if they become coaches like Maradona) Anyway, long question short, if you're happen to be working in this field or have some knowledge, please shed some lights.

• Click Listener not invoked within ListFragment

  - by membersound

  I'm extending a SherlockListFragment, but it should not matter as my question seems to be more general related to Fragments. Now, I implement a simple click listener for my list, but it does not get called. public class MyListFragment extends SherlockListFragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View v = inflater.inflate(R.layout.list, container, false); v.setOnClickListener(new OnClickListener() { public void onClick(View view) { Log.i("debug", "single click"); } }); return v; } } Is anything wrong with this? //Solution: listView.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Log.i("debug", "single click"); } });

• How do you handle exceptions from API/library in your code?

  - by 5YrsLaterDBA

  I have the following lines of code: FileInfo dbFile = new FileInfo(fileName); dbFileSize = (long)dbFile.Length / 1024;//KB There are 8 possible exceptions from new FileInfo(fileName) and dbFile.Length calls. I cannot just ignore them. I have to catch them. What you are going to do with those 8 exceptions? Catch them separately (too many lines)? Catch only ONE by catching the super Exception excepton? or ...

• How to to dump JS array... (boommarklet?)

  - by Soulhuntre

  A page on a site I use is holding some of my data hostage. Once I have logged into the site and navigated to the right page, the data I need is in the array eeData[] - it is 720 elements long (once every 2 minutes of a given day). Rather than simulate the requests to the underlying stuff json supplier and since its only once a day, I am happy to simply develop a bookmarklet to grab the data - preferably as a XML or CSV file. Any pointers to sample code or hints would help. I found a bookmarklet here that is based on this script that does part of this - but I am not up to speed on any potential JS file IO to see if it is possible to induce a file "download" of the data, or pop it opn in a new window I can copy / paste.

• Generic object load function for scala

  - by Isaac Oates

  I'm starting on a Scala application which uses Hibernate (JPA) on the back end. In order to load an object, I use this line of code: val addr = s.load(classOf[Address], addr_id).asInstanceOf[Address]; Needless to say, that's a little painful. I wrote a helper class which looks like this: import org.hibernate.Session class DataLoader(s: Session) { def loadAddress(id: Long): Address = { return s.load(classOf[Address], id).asInstanceOf[Address]; } ... } So, now I can do this: val dl = new DataLoader(s) val addr = dl loadAddress(addr_id) Here's the question: How do I write a generic parametrized method which can load any object using this same pattern? i.e val addr = dl load[Address](addr_id) (or something along those lines.) I'm new to Scala so please forgive anything here that's especially hideous.

• Allow users to enter a variable length list of items in asp.net form

  - by EJB

  I need to let my users enter a variable length list of items into something that looks like a grid view (or a series of standard text boxes stacked vertically). Each item could be a few characters or a few hundred characters long, and I just want them to enter a "sentence", and then tab to the next row, and always having another blank one ready to go at the bottom of the list. I don't want to save any data to my SQL Server DB until they enter the entire list and then click on a "save all" button. When they hit the "save all" button they will be given a preview screen where the data will be presented as standard HTML ordered list. If they confirm/save, then each row of the grid will then be saved as a separate row into my SQL Server database (with an index to remember the order). What ASP.Net (or Jquery/javascript) UI control would be the best to use in this situation?

• Oracle spatial search within distance

  I have the following table Cities: ID(int),City(char),latitude(float),longitude(float). Now based on a user`s longitude(ex:44.8) and latitude(ex:46.3) I want to search for all the cities near him within 100 miles/KM. I have found some examples but don`t know how to adapt them to my case select * from GEO.Cities a where SDO_WITHIN_DISTANCE([I don`t know], MDSYS.SDO_GEOMETRY(2001, 8307, MDSYS.SDO_POINT_TYPE(44.8,46.3, NULL) ,NULL, NULL), 'distance = 1000') = 'TRUE'; Any help would be appreciated.

• Recover a deleted webpage

  - by rc

  Suppose, a blog or a nice article was hosted on a website and it got deleted or worse the website was brought down. How do you view that web page? I tried searching for the cached version in Google. But, looks like the content was deleted long ago and is not listed in the search results directly. There are annotations to the link from many other sites, but still the actual content is not fully available. Now, can anybody help me see this page... I am actually looking for http://effectize.com/become-coolest-programmer :) And, moreover, in addition to bookmarking a favorite link, is it possible to cache the content of the link as well for later reference in case it gets deleted? EDIT: Looks like a URL can be cached for future reference. Try: http://backupurl.com/

• MySQL: Order by time (MM:SS)?

  - by Shpigford

  I'm currently storing various metadata about videos and one of those bits of data is the length of a video. So if a video is 10 minutes 35 seconds long, it's saved as "10:35" in the database. But what I'd like to do is retrieve a listing of videos by length (longest first, shortest last). The problem I'm having is that if a video is "2:56", it's coming up as longest because the number 2 is more than the number 1 in. So, how can I order data based on that length field so that "10:35" is recognized as being longer than "2:56" (as per my example)?

• Adding index key in Grails' Domain

  - by firnnauriel

  I tried following this reference and this is now my domain's code: class SnbrActVector { long nid String term double weight static mapping = { version false nid index:'Nid_Idx' } static constraints = { term(blank:false) } } What I want is to do is to add an index key for 'nid' column. I dropped the existing table and run the app again so the table is then recreated. However, when i check for list of indices, I can't see a 'Nid_Idx', only available is 'PRIMARY'. Do I have to manually create the index and name it 'Nid_idx in my mysql database? Thanks.

• Jquery How to use history plugin?

  - by Martijn

  In my web application I am using ajax and now I'd like the back and forward browser buttons to work. So I went looking for a jquery history plugin and found this one: http://stilbuero.de/jquery/history In my code I use a function to load a page: function loadDocument(id, doc) { $("#DocumentContent").show(); // Clear dynamic menu items $("#DynamicMenuContent").html(""); $("#PageContent").html(""); // Load document in frame $("#iframeDocument").attr("src", 'ViewDoc.aspx?id=' + id + '&doc=' + doc + ''); // Load menu items $("#DynamicMenuContent").load("ShowButtons.aspx"); } As you can see I want my pages to load within an Iframe. Can someone tell me how I can use a history plugin so that the brwoser buttons will work? I don't really care which plugin it is, as long as the browser buttons work. I prefer an easy to use plugin.

• I want to make a 2D color plot showing stress magnitude (S) at very loctaion (x, y) based on continuous color change using limited data sets

  - by Alex Liu

  friends, I have to trouble you as I couldn't find a solution after trying for a long time. I have 3 columns of data. x, y, and the stress value (S) at every point (x, y). I want to generate a 2D color plot displaying continuous color change with the magnitude of the stress (S). The stress values increase from -3*10^4 Pa to 4*10^4 Pa. I only have hundreds of data sets for an area, but I want to see the stress magnitude (read from the color) at every location (x, y). What Matlab command should I use? Thank you very much!

• Android Static Variable Scope and Lifetime

  - by Edison

  I have an application that has a Service uses a ArrayList to store in the background for a very long time, the variable is initialized when the service started. The service is in the background and there will be frequent access to the variable (that's why i don't want to use file management or settings since it will be very expensive for a file I/O for the sake of battery life). The variable will likely to be ~1MB-2MB over its life tie. Is it safe to say that it will never be nulled by GC or the system or is there any way to prevent it? Thanks.

• How to cast/convert form Object in an byte[] array

  I've got a maybe simple problem, but at the moment I am not able to solve it. I have an Object and I need to convert it into a byte[]. public byte[] GetMapiPropertyBytes(string propIdentifier) { return (byte[])this.GetMapiProperty(propIdentifier); //InvalidCastException } Exception: Unable to cast COM object of type 'System.__ComObject' to class type 'System.Byte[]'. Instances of types that represent COM components cannot be cast to types that do not represent COM components; however they can be cast to interfaces as long as the underlying COM component supports QueryInterface calls for the IID of the interface. So far so good - I've tried to serialize it, but I got another exception - NOT serializable Could someone help me? I need a method to convert it...

• How to make a custom installer for games, etc?

  - by Dodi300

  Hello. Can anyone tell me how to create a custom installer to 'install' games. I say custom meaning I don't want the user to have the option where the game is installed. I want it to be a straight forward process, maybe with just one loading bar. The program I'm developing is a 'center' for game playing, which includes a community and other features, such as a timer that records how long a game is played for. I just thought that installing each game in one place, with a simple installer would make the program easier to use. It also will allow me to do other features as the games will all be installed in one place. No need for the user to specify where the game is installed. Would this be possible?
