• Best way to integrate searching with pagination

  - by Vijay Choudhary

  I have a web application build on cakephp 2.x. I have integrated pagination on my data. Now i want to implement searching on that data also, and pagination should work according to search result. Now my question is: Should i use a form to post my search string. If so, then which method should i use, GET or POST. OR, should i use javascript window.location method, and append the search string to it. If we use this method then search string can append more than once to url. Or any other best way to implement this. Can anybody give the best solution for this as it is a common task for each application to have.

• Where does one get data like Country:(list) State:(list)

  - by rlb.usa

  As a programmer of data-entry forms of all kinds, I often find myself making fields for things like Country: <choose from list>, State: <choose from list>, Race/Ethnicity: <choose from list>. Consider: Perhaps a list the 50 United States names is an easy thing to find (does one include DC?) , but the countries are not. Nearly every site you find has a differing list with all of the political goings on over the years, and they become outdated quickly. What's the best/common practice regarding population of these kinds of lists? Where does this data come from if it's not given in the specs?

• I'm maintaining a java class that's 40K lines long.. problem?

  - by Billworth Vandory

  This may be a subjective question leading to deletion but I would really like some feedback. Recently, I moved to another very large enterprise project where I work as a C++ developer. I was aghast to find most classes in the project are anywhere from 8K to 50K lines long with methods that are 1K to 8K lines long. It's mostly business logic dealing with DB tables and data management, full of conditional statements to handle the use cases. Are classes this large common in large enterprise systems? I realize without looking at the code it's hard to make a determination, but have you ever worked on a system with classes this large?

• centering image vertically in all resolutions

  - by gnomixa

  I need to be able to center the image vertically for all the common resolutions. A lot of ppl here on SO have already asked this question before, and 90% of then give this tutorial http://www.jakpsatweb.cz/css/css-vertical-center-solution.html as an answer. However, when viewed at my 1280 by 1024 res monitor in FF, it's not centered. And worse yet, it breaks horribly in IE7. So, it's definitely NOT the answer. Am I chasing the impossible dream? The solution has to work for FF and IE 6/7 the solution can be anything that would work, though being a bit of a purist, I would prefer a div over table:)

• Multiple Concurrent Changes Using SVN, GIT, and CVS

  - by KlaxSmashing

  At work, we are using SVN, CVS, and GIT because there any many projects that were started at various times. Anyway, a common sequence that occurs is as follows: Working on task A, making changes to project Has new task B, some bug or functionality needs to be done on project, independent of task A but may affect same set of files Check in task B Check in task A Unfortunately, what I do at this time is two maintain 2 working copies of each project. So I can always work on task B from a clean copy. As you can imagine, this is wasteful and also, does not scale well (task C, D, E, etc.) For each of these versioning systems, are there commands that can help me do the following: "Save" task A, reverting working copy to current repository Work on task B, check in changes "Restore" task A changes back to working copy

• Gradient boosting predictions in low-latency production environments?

  - by lockedoff

  Can anyone recommend a strategy for making predictions using a gradient boosting model in the <10-15ms range (the faster the better)? I have been using R's gbm package, but the first prediction takes ~50ms (subsequent vectorized predictions average to 1ms, so there appears to be overhead, perhaps in the call to the C++ library). As a guideline, there will be ~10-50 inputs and ~50-500 trees. The task is classification and I need access to predicted probabilities. I know there are a lot of libraries out there, but I've had little luck finding information even on rough prediction times for them. The training will happen offline, so only predictions need to be fast -- also, predictions may come from a piece of code / library that is completely separate from whatever does the training (as long as there is a common format for representing the trees).

• [Javascript] Retrieve a URL of a frame

  - by Ricky

  Hi, guys: If I get a link <a href="/Users/ChangePassword.aspx" target="mainFrame"> in fraTopMenu, what (1) javascript can I add to get the current mainFrame's URL upon clicking the link and (2) append the URL to the querystrings? <frameset rows="60,*" cols="*" frameborder="no" border="0" framespacing="0"> <frame src="/Common/Manager/TopMenu.aspx" name="fraTopMenu" scrolling="no" noresize="noresize" id="fraTopMenu" title="" /> <frameset rows="*" cols="185,*" framespacing="0" frameborder="no" border="0"> <frame src="..." name="leftFrame" id="leftFrame" title="" /> <frame src="..." name="mainFrame" id="mainFrame" title="" /> </frameset> </frameset> Thank you.

• SQL Server - how to determine if indexes aren't being used?

  - by rwmnau

  I have a high-demand transactional database that I think is over-indexed. Originally, it didn't have any indexes at all, so adding some for common processes made a huge difference. However, over time, we've created indexes to speed up individual queries, and some of the most popular tables have 10-15 different indexes on them, and in some cases, the indexes are only slightly different from each other, or are the same columns in a different order. Is there a straightforward way to watch database activity and tell if any indexes are not hit anymore, or what their usage percentage is? I'm concerned that indexes were created to speed up either a single daily/weekly query, or even a query that's not being run anymore, but the index still has to be kept up to date every time the data changes. In the case of the high-traffic tables, that's a dozen times/second, and I want to eliminate indexes that are weighing down data updates while providing only marginal improvement.

• Distribution of many small classes

  - by Moo-Juice

  Hi All, I have a base class called EventArgs. Derived from this are many, many specializations that represent event arguments for a particular kind of event. Consumers of these events may need some, many, or very few of these argument classes. My question is, would you provide a header file for each type (e.g, 50+ header files for the varying ones), would you try to group them in to families and have a 'common' header file for those, or would you throw caution to the window and throw them in to one easy-of-use header file that can just be included? Another approach might be to have 50 header files, and then I could introduce some "family" header files that included particular ones. Not sure about the naming conventions for these kinds of things so it is obvious what is where. I know there may not be a hard and fast rule, but wondering what other developers have done when they find themselves writing many little classes. Thanks in advance.

• Hudson pipelines

  - by johnoc

  Hi Can anyone help with this problem? I have a test job, a downstream job and a join job. I only want the join job to run if the downstream job succeeds. If the test job fails and the downstream job succeeds I still want to run the join job. Anyone know of a plugin that can help here? The join plugin is not good enough because I can configure it to run join job when test AND downstream succeed, or run join regardless of either jobs success/failure. But not run join job ONLY if downstream succeeds. Why do I want to do it this way? I want to pipeline jobs together but only if a common "downstream" job succeeds. If it fails then I want the pipeline to "break". Many thanks John

• How would you find the height of objects given an image?

  - by Ram Bhat

  Heyguys.. This isn't exactly a programming question exactly. I just want to know what your approach would be to a common problem in Digital image processing. Lets say you have an image of a a few trees in say jpg format. How would you go about finding the heights of each of these trees. The photo is the only input you have. I want to know the approaches you have not code. So it doesnt matter if your answers are vague, or non DIP-ish.

• Way of knowing who called a singleton - objective C

  - by Cyril

  Hello, I am designing a game with several levels. I have a CCLayer defined as a singleton (called MasterScene) where I handle the pause page, transition page, player's score banner,... all the things common to all levels. So in each level, when the user pushes the pause button, a call is made to the singleton to display the CClayer corresponding to the pause page. My problem is that I want to know who called the singleton (which level) t. Is there a way of doing that ? Thanks

• Is it possible to get the current request that is being served by node.js?

  - by user420504

  I am using express.js. I have a need to be able to log certain request data whenever someone tries to log a message. For this I would like to create a helper method like so function log_message(level, message){ winston.log(level, req.path + "" + message); } I would then use the method like so. exports.index = function(req, res){ log_message("info", "I'm here"); } Note that I am not passing the req object to the log_message function. I want that to be transparently done so that the log_message API user does not need to be aware of the common data that is being logged. Is there a way to achieve this with express.js/node.js. Is the request object available from a global variable of some sort?

• Working with sets of rows in (My)SQL and comparing values

  - by Pep.

  Hello, I am trying to figure out the SQL for doing some relatively simple operations on sets of records in a table but I am stuck. Consider a table with multiple rows per item, all identified by a common key. For example: serial model color XX1 A blue XX2 A blue XX3 A green XX5 B red XX6 B blue XX1 B blue What I would for example want to do is: Assuming that all model A rows must have the same color, find the rows which dont. (for example, XX3 is green). Assuming that a given serial number can only point to a single type of model, find out the rows which that does not occur (for example XX1 points both to A and B) These are all simple logically things to do. To abstract it, I want to know how to group things by using a single key (or combination of keys) and then compare the values of those records. Should I use a join on the same table? should i use some sort of array or similar? thanks for your help

• [cli/linux] get plain text from raw emails (not attachments extraction)

  - by etuardu

  Hi, having a raw email as input (i.e. the text between "DATA" and "." sent by a smtp client) I need to extract the mail content (which I know is always text only) as plain text. This means decoding transfer encoding (if any: could be base64 or quoted-printable), merging mutiparts (if any), and stripping headers. I tried various tools that would do that: mewdecode, uudecode, uudeview... I only managed to get this last one to work, but it won't output anything if the mail is not MIME encoded and it stores its output in an unpredictable (nor forceable) filename, so it's hard to use it in a not-interactive shell script. Since this is a pretty common job (every mail client have to do that), it's weird it's so complicated. Do you have some hints? (Actually, forcing uudeview to output in a certain file would be good enough). Thank you!

• How do I inherit abstract unit tests in Ruby?

  - by Graeme Moss

  I have two unit tests that should share a lot of common tests with slightly different setup methods. If I write something like class Abstract < Test::Unit::TestCase def setup @field = create end def test_1 ... end end class Concrete1 < Abstract def create SomeClass1.new end end class Concrete2 < Abstract def create SomeClass2.new end end then Concrete1 does not seem to inherit the tests from Abstract. Or at least I cannot get them to run in eclipse. If I choose "Run all TestCases" for the file that contains Concrete1 then Abstract is run even though I do not want it to be. If I specify Concrete1 then it does not run any tests at all! If I specify test_1 in Concrete1 then it complains it cannot find it ("uncaught throw :invalid_test (ArgumentError)"). I'm new to Ruby. What am I missing here?

• Some tables mixed together

  - by DJPython

  Hello. I have 2 different tables in my database. They have some variables common and some different. For example: Table1: ID Date Name Address Fax Table2: ID Date Name e-mail Telephone number I want to display data together sorted by date & ID but from both tables. For example, first displayed will be the newest record from first table, but the second one will be the record from another table posted right after first one. Hope everybody understand, sorry for my English. Cheers.

• CodeIgniter won't run in a subdirectory

  - by Tim Piele

  I have a CodeIgniter install running in our root web directory that I copied into a subdirectory called /dev... I edited the config/config.php file to reflect the change so it is now like this: $config['base_url'] = 'http://mysite.com/dev'; $config['sbase_url'] = 'https://mysite.com/dev'; $config['default_email'] = '[email protected]'; $config['site_url'] = 'http://mysite.com/dev'; This is my .htaccess file: <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php/$1 [L] </IfModule> When I hover over any links on the site they are correct, for example the contact us page link reads www.mysite.com/dev/contact but when I click any of the links I get a 404 error... Is there something common I am missing?

• Java inheritance question

  - by user247866

  So I have 3 classes. Abstract class A Class B extends class A independent Class C In class D that contains the main method, I create a list of instances of class B List<B> b = method-call();` // the method returns a list of instances of class B Now in class C I have one method that is common to both A and B, and hence I don't want to duplicate it. I want to have one method that takes as input an instance of class A, as follows: public void some-method(LIst<A> a) However, when I do: C c = new C(). c. some-method(b) I get an error that some-method is not applicable for the argument List, instead it's expecting to get List. Is there a good way to fix this problem? Many thanks!

• What Android version to target?

  - by Richard Eng

  I'm about to write my first Android app. It's a fairly basic app that doesn't use any special features beyond being able to schedule notifications and read/write image files to the device's local storage. Reaching the broadest audience is my top priority. If I target Android 1.5, is the app guaranteed to run fine all the way up to ICS? Should I target Android 2.1, which seems to be the new baseline for common phones in use? Since the app is fairly basic, if I target ICS, would it run on versions going all the way back to 2.1? Maybe this is a stupid question.

• @MustOverride annotation?

  - by Harrypotter2k5

  In .NET, one can specify a "mustoverride" attribute to a method in a particular superclass to ensure that subclasses override that particular method. I was wondering whether anybody has a custom java annotation that could achieve the same effect. Essentially what i want is to push for subclasses to override a method in a superclass that itself has some logic that must be run-through. I dont want to use abstract methods or interfaces, because i want some common functionality to be run in the super method, but more-or-less produce a compiler warning/error denoting that derivative classes should override a given method.

• .net File.Copy very slow when copying many small files (not over network)

  - by Guavaman

  I'm making a simple folder sync backup tool for myself and ran into quite a roadblock using File.Copy. Doing tests copying a folder of ~44,000 small files (Windows mail folders) to another drive in my system, I found that using File.Copy was over 3x slower than using a command line and running xcopy to copy the same files/folders. My C# version takes over 16+ minutes to copy the files, whereas xcopy takes only 5 minutes. I've tried searching for help on this topic, but all I find is people complaining about slow file copying of large files over a network. This is neither a large file problem nor a network copying problem. I found an interesting article about a better File.Copy replacement, but the code as posted has some errors which causes problems with the stack and I am nowhere near knowledgeable enough to fix the problems in his code. Are there any common or easy ways to replace File.Copy with something more speedy?

• Run ajaxed javascript

  - by user1905698

  I know this has been covered a few times, but I'm completely a noob when it comes to javascript so I have no idea what I'm doing. I am running a javascript that sends variables to a php file and that info is ajaxed into the current page using innerhtml. Here is that part of the code... `function givingHistory(dyear,did) { var divname="giving" + dyear; $.ajax({ url: 'finance/givinghistory.php', type: 'POST', data: { year: dyear, id: did }, success: function(givedata) { document.getElementById(divname).innerHTML = givedata; } }); } ` In the givedata function response from the php file there is a call to another javascript function that is already loaded in my common .js file (so both javascript functions are loaded when the page loads). How do I get the onClick that is added via innerhtml to work? Inside the php file, I check to see if id = a php session variable. If it does it spits out the text that includes the onClick.
