  • Ruby on Rails: Best way to save search queries in a database

    - by Adam Templeton
    For a RoR app I'm helping develop, I need to save all search queries in a database so I can analyze them later. My plan right now is to create a Result model and table, and just save each search query's text in that table, along with a user's ID, the time, etc. However, the app has about 15,000 users, so I'm afraid the single table approach won't be super efficient when it comes time to parse that data. (The database is setup via MySQL, if that factors in at all.) Am I just being paranoid? Is there a Ruby gem that handles this sort of thing, or a better approach I could take? Any input would be appreciated.

  • Keeping track of threads when creating them recursively

    - by 66replica
    I'm currently working on some code for my Programming Languages course. I can't post the code but I'm permitted to talk about some high level concepts that I'm struggling with and receive input on them. Basically the code is a recursive DFS on a undirected graph that I'm supposed to convert to a concurrent program. My professor already specified that I should create my threads in the recursive DFS method and then join them in another method. Basically, I'm having trouble thinking of how I should keep track of the threads I'm creating so I can join all of them in the other method. I'm thinking an array of Threads but I'm unsure how to add each new thread to the array or even if that's the right direction.

  • Creating WebService test harness

    - by user232337
    Hello, I am trying to create a test harness for our QA staff to test our internal web services. I would like to create a web app that will allow them to enter a uri then submit. The web app will then interrogate the uri to get the appropriate parameters expected and returns with a generated input form. I know, this would be similar to SOAPUI and others. However, I feel it would be earier for them to be able to just use a form with entry fields and click a button to invoke the service and get the results back for display in the web app. In addition, I could create some custom logic that allows them to generate specific behavior they need. Has anybody done anything like this? I have searched and have found similar functionality but nothing close enough to help me. If you need more details please let me know. Any help would be greatly appreciated. Thanks in advance! Ryan

  • Are these 2 sql queries equivalent in all respects (e.g. estimated and actual execution plan)?

    - by Xerion
    Are query 1) == 2) in terms of estimated query plan AND actual plan? (can statistics affect the actual plan here, ever?) declare @cat int -- input param from prc ... 1) select * from A as a join B as b on b.id = a.id on b.cat = @cat join C as c on c.fid = b.fid on c.cat = @cat where a.cat = @cat 2) select * from A as a join B as b on b.id = a.id on b.cat = a.cat join C as c on c.fid = b.fid on c.cat = b.cat where a.cat = @cat It seems to me that these should logically be equivalent and the execution plan should always be the same regardless of actual difference in tables. And adding more conditions either in join, or where, or add more tables to join shouldn't change this. Are there cases this is not true?

  • Statistics help on 3 choices

    - by DaveSav
    I'm working on an Android app where, at one point, the user is asked to input whether something helped. Their options are 'Yes', 'No' and 'Don't Know'; or they could choose to ignore it. This is for multiple 'somethings' over a date range. A summary view for a date range shows the percentage of 'Yes', 'No' and 'Don't Know' entered for each 'something'. I'm also showing the 'Overall Effectiveness' as the percentage of 'Yes' inputs, which I realise is incorrect. I am thinking of changing that to 'Yes' minus 'No', but that doesn't address the 'Don't Know' inputs. How would I handle the data so that 'Overall Effectiveness' represents all 3 data inputs? So, for a 'something' which has a 'Yes' of 25%, a 'No' of 25% and a 'Don't Know' of 50%, would that be an 'Overall Effectiveness' of 0% ? Or would the 'Don't Know' affect that figure at all? As an additional to that, what graph type, other that Pie, would best display all 3 data?

  • ASP.NET MVC Model Binders, html id

    - by Stacey
    Using the Model Binders in ASP.NET MVC 2.0, you can do something like this... [DisplayName("User Name")] public string Name { get; set; } <%: Html.TextBoxFor( m => m.Name ) :%> and then in your HTML, you get a result like this.. <label for="UserName">User Name</label> <input type="text" id="UserName" name="UserName" /> That works fine, but I want to have better control over the HTML ID. Is there any way to do this through the model binding method?

  • Detect EXIF Orientation of an image in javascript

    - by Obi Wan
    In my mobile web application, I have a need to examine the EXIF orientation tag of an image file selected using an input type=file control, and this needs to be done on the client side in javascript, before the selected image file gets uploaded to the server. I have seen several threads similar to this but most of them say to use a library called binaryajax.js to be able to access the EXIF data from the file object. Unfortunately, simply including binaryajax.js in my project causes an Access Denied error in jQuery 1.7.1, and I have no idea why this is happening. This error precludes me from using this jquery library. So I am looking for a solution that does not use this library. Another library I have tried to use is jquery.exif.js and I also get an Access Denied Error Trying to use it.

  • Stackoverflow interesting tags

    - by Tom
    So, that's how works Interesting Tags: I add into them my interested tags like php, mysql, jquery and so on. Then, if any of questions has the same tags as mine it makes background orange. I understand how to use jquery to do that (there were related questions to that), but without mysql it can't be done. Now, here is a question. How is it done? I imagine like that: There is a row in mysql for every member, let's call it "interested_tags". After I write and submit my tag through input, it is being written in a row "interested_tags". Then, the main page has a query which shows all answers and it always checks answer's with mine tags with strpos like this if(strpos($question_tags, $my_tags) === true) {        //and here will be made background orange } Am I thinking right or is there any way to do it?

  • Need data on disk drive management by OS: getting base I/O unit size, “sync” option, Direct Memory A

    - by Richard T
    Hello All, I want to ensure I have done all I can to configure a system's disks for serious database use. The three areas I know of (any others?) to be concerned about are: I/O size: the database engine and disk's native size should either match, or the database's native I/O size should be a multiple of the disk's native I/O size. Disks that are capable of Direct Memory Access (eg. IDE) should be configured for it. When a disk says it has written data persistently, it must be so! No keeping it in cache and lying about it. I have been looking for information on how to ensure these are so for CENTOS and Ubuntu, but can't seem to find anything at all! I want to be able to check these things and change them if needed. Any and all input appreciated.

  • Swing: Programmatically select a text

    - by HH
    Hey everyone, I have a very simple Swing GUI with just a JTetxtArea. I am trying to programmatically select a part of text using: textArea.select(startSelection,endSelection); This work. However as soon as I add some other components to the GUI I do not see selection anymore frame.getContentPane().add(button); frame.getContentPane().add(textArea); textArea.select(startSelection,endSelection); I suspect that during layouting the gui, some event causes the text to be deselected. Am I right? And could anybody suggest a solution? My goal is to have a program which displays a text, and allows the user to input start and end selection position, and a selection appears between these two position. Thank you.

  • how to avoid storing several times a repeated field of a Symfony form?

    - by user454760
    Hello everybody, I am working with Symfony 1.4 and Doctrine. I have a model A with an email field. The form of A displays an input in which the user should insert the email correctly. But as everybody knows, sometimes they don't do it. To fix this I have inserted an extra field in the model (and in the form), called *repeat_email* to prevent the misspellings. Then, in the validation process, after validating all the fields, i use a global validator to compare the data of the two fields. This works, but I don't want to have the email stored two times in the database (I don't want the *repeat_email*). Is there any mechanism to use it in the validation process, but not to store it in the database? Thanks,

  • How to add an audio filter to AudioRecord (on Android)?

    - by Jim
    I would like to write a "daemon" application that will add a special audio filter (e.g. audio enhancement) to AudioRecord. The result should be as follows: Whenever any VoIP application (e.g. Skype,...) will create an AudioRecord, the captured audio will be first filtered using my daemon application before it reaches Skype. Is this doable ? For example can I use an AudioSessionID=0 to attach my filter to all the input channels ?

    Im trying to make a script that will go into a directory and run my own application with each file matching a regular expression, specifically "Test[0-9]*.txt". My input filenames look like this "TestXX.txt". Now, I could just use cut and chop off the Test and .txt, but how would I do this if XX wasn't predefined to be 2 numbers? What would I do if i had "Test1.txt" ... "Test10.txt"? In other words, How would I get the [0-9]* part? Just so you know, I want to be able to make a OutputXX.txt :)

  • Check if NSString "000001XX"is a number with intValue

    - by Kenny
    Now I am trying to add a front end check on my app to detect if user input only number in the textfield. I use: - (IBAction)checkID:(UITextField *)sender { if ([sender.text isEqualToString:@""]) { sender.text = @"This information is required"; sender.backgroundColor =[UIColor redColor]; }else if (![sender.text intValue]) { sender.text = [sender.text stringByAppendingString:@" is not valid number"]; sender.backgroundColor =[UIColor redColor]; } NSLog(@"send.text is %@, intValue is %d",sender.text,[sender.text intValue]); } But I found it text begins with number and ends with string, its intValue is still the number. In my text, text is "00001aa", but the intValue is 1. Is there any other way to filter out this "00001aa" text? Thanks in advance.

  • Converting time period strings to value/unit pair

    - by randomtoor
    I need to parse the contents of a string that represents a time period. The format of the string is value/unit, e.g.: 1s, 60min, 24h. I would separate the actual value (an int) and unit (a str) to separated variables. At the moment I do it like this: def validate_time(time): binsize = time.strip() unit = re.sub('[0-9]','',binsize) if unit not in ['s','m','min','h','l']: print "Error: unit {0} is not valid".format(unit) sys.exit(2) tmp = re.sub('[^0-9]','',binsize) try: value = int(tmp) except ValueError: print "Error: {0} is not valid".format(time) sys.exit(2) return value,unit However, it is not ideal as things like 1m0 are also (wrongly) validated (value=10,unit=m). What is the best way to validate/parse this input?

  • ASP.NET MVC 2 Form Not Passing Values

    - by Wayne
    Hi, I have a strange problem happening today. I am running the latest version of the MVC V2 framework and have been having no trouble at all - I came in this morning and for some reason values aren't being passed in to actions. To clarify lets say I have something like this: <% using (Html.BeginForm("Register", "Registration", FormMethod.Post)) { %> .... <input type="submit" name="register" id="register" value="Register" /> <% } %> And in my controller I have the following: [HttpPost] public ActionResult Register(RegistrationModel model, string register) { // At this point the register string is null } This has been working fine for a while now and I have not changed anything that I can think of that would cause this to happen. Does that make sense and as anyone any idea what is going on or what I have messed up? Thanks.

  • How to limit a request execution time of WCF service?

    - by Kamarey
    Is there something in WCF configuration that defines a timeout for executing a request at service side? E.g. WCF service will stop executing request after some time period. I have a service which make some work depending on client input. In some cases a such call may take too much time. I want to limit the execution time of such requests on service side, not client one using SendTimeout. I know about OperationTimeout property, but it doesn't abort the service request, it just tells a client that the request is timed out.

  • Image-free, custom-styled search bar

    - by Jon
    I'm working with the designer and he sent me the following design for the search bar on our webpage: I'm very much against using images in webpage design unless completely necessary, so I'm hoping that I can recreate the whole search bar widget in CSS. I know how to do border-radius, gradients, box-shadows, etc, so that's not a problem. Question: Assuming CSS3 browser compatibility, how can I go about recreating the actual search button (the magnifying glass portion) with the double curved edge, and the slight drop shadow on the bottom left? Thoughts: My initial feeling was that the search button would be circular and free-standing, then overlap the search input div with a negative left-margin, but then I was unsure how I would get that drop shadow. Edit: I'm not completely opposed to using an image for the magnifying glass, but I've seen a similar icon created in CSS before. Would an image vs. pure CSS end up loading at the same speed, or should I do all I can do in pure CSS?
