  • mysql stored routine vs. mysql-alternative?

    - by user522962
    We are using a mysql database w/ about 150,000 records (names) total. Our searches on the 'names' field is done through an autocomplete function in php. We have the table indexed but still feel that the searching is a bit sluggish (a few full seconds vs. something like Google Finance w/ near-instant response). We came up w/ 2 possibilities, but wanted to get more insight: Can we create a bunch (many thousands or more) of stored procedures to speed up searches, or will creating that many stored procedures bog-down the db? Is there a faster alternative to mysql for "select" statements (speed on inserting & updating rows isn't too important so we can sacrifice that, if necessary). I've vaguely heard of BigTable & others that don't support JOIN statements....we need JOIN statements for some of our other queries we do. thx

  • Creating a System.Windows.Controls.Image throws an exception - how do I use the dispatcher to instan

    - by Scott Whitlock
    I'm running my unit tests on a piece of code that does the following in the test: Assert.IsNotNull(target.Icon); Inside the getter for the Icon property, I'm doing this: System.Windows.Controls.Image img = new System.Windows.Controls.Image(); That's throwing this exception: System.InvalidOperationException : The calling thread must be STA, because many UI components require this. I understand what that means, and I understand that I need to use the Dispatcher, but I'm a bit confused about how or why... this is a property of my ViewModel and I don't get any of these exceptions when running the application. Other info: this only started failing when I upgraded to .NET 4.

  • I'd want a method to be called only by objects of a specific class

    - by mp
    Suppose you have this class: public class A { private int number; public setNumber(int n){ number = n; } } I'd like the method setNumber could be called only by objects of a specific class. Does it make sense? I know it is not possible, is it? Which are the design alternatives? Some well known design pattern? Sorry for the silly question, but I'm a bit rusty in OO design.

  • About curse of dimensionality

    - by Dan
    My question is about this topic I've been reading about a bit. Basically my understanding is that in higher dimensions all points end up being very close to each other. The doubt I have is whether this means that calculating distances the usual way (euclidean for instance) is valid or not. If it were still valid, this would mean that when comparing vectors in high dimensions, the two most similar wouldn't differ much from a third one even when this third one could be completely unrelated. Is this correct? Then in this case, how would you be able to tell whether you have a match or not?

  • Graphing special functions in Matlab (2D Bessel)

    - by favala
    I'm trying to essentially get something like this where I can see clear ripples at the base but otherwise it's like a Gaussian: This is kind of unsatisfactory because the ripples aren't very noticeable, it has a very gritty quality that obscures the image a bit, and if you move the graph so that it's just in 2D (so it looks like a circle) I'm not even sure if it's quite like how it should be (the concentric circles seem to be more evenly spaced in the real thing). So, is there a better way to do this? a = 2*pi; [X Y] = meshgrid(-1:0.01:1,-1:0.01:1); R = sqrt(X.^2+Y.^2); f = (2*besselj(1,a*R(:))./R(:)).^2; mesh(X,Y,reshape(f,size(X))); axis vis3d;

  • VIM: Columnvise Increment inside and outside?

    - by hhh
    By outside, I want solutions that does not use Vim's scripting hacks but try to reuse certain basic *ix tools. Inside Vim stuff asks for solutions to get the column-increment with inside stuff such as scripting. 1 1 1 2 1 3 1 ---> 4 1 5 1 6 . . . . Vim has a script that does column-vise icrementing here. It has gathered about 50/50 ups and down, perhaps tasting a bit reinventing-the-wheel. How do you column-increment stuff in Vim without using such script? Then the other question is, how do you column-increment stuff without/outside Vim? Most elegant, reusable and preferrably-small wins the race!

  • Getting back into C/C++ after several years

    - by themaninthesuitcase
    While at university I started my first programming with ANSI C, before we moved onto Java later in the course. Now I would like to go back to (re)learning C and C++ again to allow me to contribute with open source projects and also to expand my CV and improve my career prospects. Currently I mostly program in VB.net (I know I know, I try to not do things the nasty way you can with this) and am slowly picking up C# as I get some time at work. I also use a bit of java for Android dev. While I realise just doing it is the best way to learn, my exercise ideas are usually either trivial or beyond my current skills. What are some good sources for this initial relearn, I intend to possibly start helping with Chromium as other people seem to think this a good place to get started in OS. Basically any help getting back into this would be appreciated.

  • Querying Same Lookup Table With Multiple Columns

    - by dmaruca
    I'm a bit confused on this. I have a data table structured like this: Table: Data DataID Val 1 Value 1 2 Value 2 3 Value 3 4 Value 4 Then I have another table structured like this: Table: Table1 Col1 Col2 1 2 3 4 4 3 2 1 Both columns from Table1 point to the data in the data table. How can I get this data to show in a query? For example, a query to return this: Query: Query1 Column1 Column2 Value 1 Value 2 Value 3 Value 4 Value 4 Value 3 Value 2 Value 1 I'm familiar enough with SQL to do a join with one column, but lost beyond that. Any help is appreciated. Sample sql or a link to something to read. Thanks! PS: This is in sqlite

  • Why does py2exe remove `help` and `license`?

    - by cool-RR
    I packaged my Python app with py2exe. My app is a wxPython GUI, in which there is an interactive Python shell. I noticed that I can't do help(whatever) in the shell. I investigated a bit and discovered that after the py2exe process, 3 items were missing from __builtin__. These are help, license, and another one I haven't discovered. Why is this happening and how can I stop it? I want the users of my program to be able to use the help function of Python.

  • Closed Source Java Applications

    - by Paul
    I am taking programming courses and we have been discussing Open Source and having a bit of an argument over the confusion. Just because Java is Open Source, the licensing on developed applications starts at the developer, correct? Someone is arguing about the use of code from a complete program just because "Java is Open Source". If I write a Java application, what are the limitations on how I can distribute it or how someone else can use it? Assume here that I DO NOT want someone having access to my source. Thanks

  • Associate specific file extensions with my delphi app - any library for this?

    - by michal
    Hi, so far if I had to associate the file extension with my application I used to simply modify the registry. However I haven't been doing it for years, and I'm afraid the things might have changed a bit. I have no idea how to prevent registry access restrictions in Windows 7 / Vista (if there are any for HKEY_CLASSES_ROOT). Thus I'm looking for some delphi library, unit, code snippet or whatever which works reliably under XP, Vista and 7. Is there any which handles "backup" as well? By backup I mean possibility to revert the changes to the previous association ... Thanks in advance, m.

  • need help in aggregate select

    - by eugeneK
    Hi, i have a problem with selecting some values from my DB. DB is in design stages so i can redesign it a bit of needed. You can see the Diagram on this image Basically what i want to select is select c.campaignID, ct.campaignTypeName, c.campaignName, c.campaignDailyBudget, c.campaignTotalBudget, c.campaignCPC, c.date, cs.campaignStatusName ***impressions, ***clicks, ***cast(campaignTotalBudget-(clicks*campaignCPC) as decimal(18,1)) as remainingFunds from Campaigns as c left join CampaignTypes as ct on c.campaignTypeID=ct.campaignTypeID left join CampaignStatuses as cs on c.campaignStatusID=cs.campaignStatusID left join CampaignVariants as cv on c.campaignID=cv.campaignID left join CampaignVariants2Visitors as c2v on cv.campaignVariantID=c2v.campaignVariantID left join Visitors as v on c2v.visitorID=v.visitorID ..... order by c.campaignID desc Problem is that Visitors table has column named isClick so i don't know the way to separate what is impression with isClick=false and what is click isClick=true so i can show nice form with all the stuff about campaign and visitors... I don't think to split Visitors to two tables like Impressions and Click is a good idea because again i would need to have Visitors with two more tables thanks

  • Is this the best way to get the size of a Paper via CUPS?

    - by Lawrence Johnston
    I've got a CUPS job control file. I need to get the actual dimensions of the print that was made. This is the way I've figure out to do it: Get the paper name using the media attribute. (e.g. Letter) Get the printer uri from the printer-uri attribute. (e.g. ipp://localhost/printers/MyPrinter) Get the printer name by passing the printer uri to the IPP_GET_PRINTER_ATTRIBUTES operation and getting the printer-name attribute. (e.g. MyPrinter) Get the path to the PPD passing the printer name to the the cupsGetPPD method. Open the PPD passing the path to the PPD to the ppdOpenFile method. Get the paper size by passing the PPD and paper name to the ppdPageSize method. This will work, but it seems a bit roundabout. Is there a more efficient way of getting what I need?

  • Strange Rendering in Firefox

    - by Alex
    I've just noticed when loading my client's page (http://habbopfm.com/) in Firefox, that it renders what looks like a rectangle is pushed down a few pixels. It's difficult to describe, but imagine you took a screenshot of the page, opened it in Photoshop, selected a rectangle and moved it down a bit. IE and Safari don't appear to do this - I'm assuming this is a browser glitch, not a problem with the code. Can anyone confirm what causes this? Below is a screenshot taken of the issue: http://habbopfm.com/problem.png One other thing is that it only does this once the page has finished loading. While it is loading, it looks fine.

  • Debugging PHP in Aptana 2.0

    - by Nick Lowman
    I'm a real newbie when it comes to PHP debugging so forgive my stupidity. I have a simple html form that submits to a PHP script and I want to debug that script and see what's being sent from the form. My Aptana has two two PHP interpreters installed; Zend Debugger on port 10001 and XDebug on 9000 I have the Firefox Aptana Addon installed I have my HTML page on the following url, running locally; http://3i/latest.html In the IDE I open the PHP script and add some breakpoints, I then open the latest.html and I click on the debug button. It launches the HTML page in a local webserver running at; http://127.0.0.1:8000/3i/latest.html I then fill out the form and submit at which point the debugger tells me the JS Debugger has terminated but it doesn't stop at my break points. I've had a good read around and I can't find anything which helps me, which makes me think it's something pretty easy and I'm being a bit dumb.

  • Data validation between SQL replicated tables

    - by Vikram
    Hi All, I am trying to figure out a way to validate the data in my publisher and subscriber in SQL 2005 replication. I thought of using sp_publication_validation, but it needs db_owner permission and we are not allowed to have it in our company. So I did bit more reading and found out about two other SPs that I think work for me. First one is sp_article_validation, which I plan to run on the publisher. For each article that I call this SP, its gonna give the row count and a checksum. With that info, I intend to call sp_table_validation on the subscriber, passing the row count and checksum from the previous SP, there by validating both tables. What do you guys think? Is this a proven way to validate data in replication? There is very little documentation on these SPs. Here is the link: sp_table_validation - http://msdn.microsoft.com/en-us/library/aa239370(v=sql.80).aspx sp_article_validation - http://msdn.microsoft.com/en-us/library/ms177511(v=SQL.90).aspx Thanks for

  • How to write a regular expression for "everything between X and Y" for use with preg_replace

    - by pg
    I want to take a variable called $encoded_str and and remove cd1, CD1 and anything between the first 'l' and the last blank space. So for example "lp6 id4 STRINGcd1" would return "STRING". I'm using PHP 4 for now so I can't use str_ireplace, I have this: $encoded_str=str_replace('CD1','',$encoded_str); $encoded_str=str_replace('cd1','',$encoded_str); $encoded_str=preg_replace('X','',$encoded_str); I've RTFM for preg_replace but am a bit confused. What should I replace the X with and can you suggest a decent introductory primer for writing regular expressions?

  • Annotation based data structure visualization - are there similar tools out there?

    - by Helper Method
    For a project at university I plan to build an annotation based tool to visualize/play around with data structures. Here's my idea: Students which want to try out their self-written data structures need to: mark the type of their data structures using some sort of marker annotation e.g. @List public class MyList { ... } so that I know how to represent the data structure need to provide an iterator so that I can retrieve the elements in the right order need to annotate methods for insertion and removal, e.g. @add public boolean insert(E e) { ... } so that I can "bind" that method to some button. Do similar applications exist? I googled a little bit around but didn't find anything like that.

  • Send serialised object via socket

    - by RubbleFord
    Whats the best way to format a message to a server, at moment I'm serilising an object using the binaryformatter and then sending it to the server. At the server end its listening in an async fashion and then when the buffer size recieved is not 100% it assumes that the transfer has complete. This is working and the moment, and I can deserialise the object at the other end, I'm just concerned that if I start sending async this method will fail has message's could be blurred. I know that I need to mark the message somehow as to say that's the end of message one, this other bit belongs to message 2, but I'm unsure of the correct way to do this. Could anyone point me in the right direction and maybe give me some examples? Thanks

  • Inserting text into a textarea using .load() in jQuery

    - by bateman_ap
    Hi, having a bit of a nightmare, I am trying to use jQuery to insert some text taken from a .load() call into a form field (textfield) after a user logs in (basically prefilling some known details) The code I am using is: $.ajax({ type: "POST", url: "/ajax/login.php", data: dataString, success: function(html) { if (html == 1) { $("#loginPanel").load("/ajax/login-panel.php"); $("#bookName").load("/ajax/getSessionDetails.php #userUsername"); $("#bookEmail").load("/ajax/getSessionDetails.php #userEmail"); $("#bookingLogin").hide("fast"); } else { $("#loginError").html("Sorry, login failed, please try again"); } } }); If I hardcode such as $("#bookName").html("Test Content"); it works OK so it must be a problem with the .load call. I looked around and found some guy suggest something like the following code but I couldn't get it to work: $.get(htmlBannerUrl, function(data){ $('textarea').val(data); });

  • Are C++ Templates just Macros in disguise?

    - by Roddy
    I've been programming in C++ for a few years, and I've used STL quite a bit and have created my own template classes a few times to see how it's done. Now I'm trying to integrate templates deeper into my OO design, and a nagging thought keeps coming back to me: They're just a macros, really... You could implement (rather UGLY) auto_ptrs using #defines, if you really wanted to. This way of thinking about templates helps me understand how my code will actually work, but I feel that I must be missing the point somehow. Macros are meant evil incarnate, yet "template metaprogramming" is all the rage. So, what ARE the real distinctions? and how can templates avoid the dangers that #define leads you into, like Inscrutable compiler errors in places where you don't expect them? Code bloat? Difficulty in tracing code? Setting Debugger Breakpoints?

  • Specifying routes by subdomain in Express using vhost middleware

    - by user730569
    I'm using the vhost express/connect middleware and I'm a bit confused as to how it should be used. I want to have one set of routes apply to hosts with subdomains, and another set to apply for hosts without subdomains. In my app.js file, I have var app = express.createServer(); app.use...(middlware)... app.use(express.vhost('*.host', require('./domain_routing')("yes")); app.use(express.vhost('host', require('./domain_routing')("no")); app.use...(middlware)... app.listen(8000); and then in domain_routing.js: module.exports = function(subdomain){ var app = express.createServer(); require('./routes')(app, subdomain); return app; } and then in routes.js I plan to run sets of routes, dependent on the subdomain variable passed in is "yes" or "no". Am I on the right track or is this not how you use this middleware?

  • RegularExpressionValidator always fails, but ValidationExpression works in testing

    - by Jerph
    I found the answer to this, but it's a bit of a gotcha so I wanted to share it here. I have a regular expression that validates passwords. They should be 7 to 60 characters with at least one numeric and one alpha character. Pretty standard. I used positive lookaheads (the (?= operator) to implement it: (?=^.{7,60}$)(?=.*[0-9].*)(?=.*[a-zA-Z].*) I checked this expression in my unit tests using Regex.IsMatch(), and it worked fine. However, when I use it in a RegularExpressionValidator, it always fails. Why?
