• is there a limit of merge tables with Mysql ?

  - by sysko

  I'm working on a database with mysql 5.0 for an open source project it's used to stored sentences in specific languages and their translations in other languages I used to have a big table "sentences" and "sentences_translations" (use to join sentences to sentences) table but has we have now near one million entries, this begin to be a bit slow, moreover, most of request are made using a "where lang =" so I've decided to create a table by language sentences_LANGUAGECODE and sentences_translation_LANGSOURCE_LANGTARGET and to create merge table like this sentences_ENG_OTHERS which merge sentences_ENG_ARA sentences_ENG_DEU etc... when we want to have the translations in all languages of an english sentence sentences_OTHERS_ENG when we want to have only the english translations of some sentences I've created a script to create all these tables (they're around 31 languages so more than 60 merge table), I've tested, that works really great a request which use to take 160ms now take only 30 :) but I discover that all my merge table after the 15th use to have "NULL" as type of storage engine instead of MRG_MYISAM, and if delete one, then I can create an others, using FLUSH table between each creation also allow me to create more merge tables so is this a limitation from mysql ? can we override it ? thanks for your answers

• Parsing through Arabic / RTL text from left to right

  - by Dan W

  Let's say I have a string in an RTL language such as Arabic with some English chucked in: string s = "Test:?????;?????;?????;a;b" Notice there are semicolons in the string. When I use the Split command like string[] spl = s.Split(';');, then some of the strings are saved in reverse order. This is what happens: ??Test:????? ????? ????? a b The above is out of order compared to the original. Instead, I expect to get this: ?Test: ????? ????? ????? a b I'm prepared to write my own split function. However, the chars in the string also parse in reverse order, so I'm back to square one. I just want to go through each character as it's shown on the screen.

• How to get variable value from inside a stored procedure in DB2?

  - by Sylvia

  This seems like it should be very easy...anyway, it is in MS SQL Server In a DB2 stored procedure, how can I just get the value of a variable? Say I have the following stored procedure: CREATE PROCEDURE etl.TestABC( ) LANGUAGE SQL BEGIN declare Stmt varchar(2048); set Stmt = 'this is a test'; -- print Stmt; -- select Stmt; return 0; END @ I'd like to print out the value of Stmt after I set it. Print doesn't work, select doesn't work. Somebody said I have to insert it to a table first, and then get it after I run the stored procedure. Is this really necessary? Thanks, Sylvia EDIT: I should have made clearer that I want to see the value of Stmt each time after I set it, and I may need to set it multiple times within the same stored procedure.

  When I connect a Sony Reader to an USB port “USB connected” is shown on the Reader. When the Sony “Reader Library” software is started this message changes to “Do not disconnect”. I want to implement this in a software tool to. There seems to be no file locked. Perhaps it is done via ebookUsb.dll. Does anybody know how this is done from any programming language? I like to see an example.

  Hello everyone, I am making a Google Analytics like project for my school assignment. I have two questions primarily: 1) Exactly when does Google store the data to the database?

• Singelton restricted to instance of dll

  - by codeySmurf

  If I create a singleton class in the context of a dll, the singleton class is instantiated once and used by all instances of the dll. I am using a dll as a plug-in for an application. Now the following thing came to my mind: If I use a singleton Class, it will be shared across multiple instances of the plug-in. However, this makes it difficult to manage the lifetime of the singleton class efficiently. The only way I could think of would be to use a reference count and to make the singleton delete its self when the reference count is 0. Does anyone have any better ideas on that? Is there any good way to restrict the singleton object to one instance of the dll? Language is c++

• How to pass an anonymous array of strings to a JavaScript function?

  - by abatishchev

  I want to pass to an array of controls' IDs to a javascript script function so it will switch control's enable state. For example, in C# it would be like this: func(false, new[] { "Control1", "Control2", "Control3" }); In that function I want to find corresponding controls and disable/enable them. For one control I do this next way: <script type="text/javascript" language="javascript"> function switchControls(value, arr) { for (var n = 0; n < array.length; n++) document.getElementById(n).disabled = value; } </script> <asp:CheckBox runat="server" onclick="switchControls(this.checked, [ '<%= Control1.ClientID %>', '<%= Control2.ClientID %>' ])" Text="Take?" /> How to implement this properly? Have I to use jQuery?

• Java generic Interface performance

  - by halfwarp

  Simple question, but tricky answer I guess. Does using Generic Interfaces hurts performance? Example: public interface Stuff<T> { void hello(T var); } vs public interface Stuff { void hello(Integer var); <---- Integer used just as an example } My first thought is that it doesn't. Generics are just part of the language and the compiler will optimize it as though there were no generics (at least in this particular case of generic interfaces). Is this correct?

• If I start learning C on Ubuntu will it give me an edge when I start learning Objective-C later this

  - by Anonymous

  I know Ruby right now, however I want to learn a new language. I am running Ubuntu 10.04 right now but I am going to get a Mac later this summer. Anyways I want something more for GUI development. I was wondering if I should learn C on Ubuntu right now, and then learn Objective-C when I get an iMac? Will learning C give me an edge? Or should I just learn Python on Ubuntu and then learn Objective-C when I get a new computer? Please give me your opinions! Thanks!

• Netbeans Intellisense for Rails

  - by irishfury

  Has anybody figured out a way to make the Netbeans intellisense for ruby and rails better? It either has too many options in the list (which I understand is a problem since it is a dynamic language). Or it has no options in the list, as if it is not dynamic enough to find everything. Are there any hacks to make it better, or is this just something that needs to be improved within the Netbeans source code? I'm currently using 6.8. Please spare me the posts about how I don't really need to use intellisense, and I should use vim or emacs. I'm sure the vim programmers are 10 times more productive than me with all their cool shortcuts, but I have no desire to learn these tools.

• How do I erase printed characters in a console application(Linux)?

  - by Binny V A

  Hi all, I am creating a small console app that needs a progress bar. Something like... Conversion: 175/348 Seconds |========== | 50% My question is, how do you erase characters already printed to the console? When I reach the 51st percentage, I have to erase this line from the console and insert a new line. In my current solution, this is what happens... Conversion: 175/348 Seconds |========== | 50% Conversion: 179/348 Seconds |========== | 52% Conversion: 183/348 Seconds |========== | 54% Conversion: 187/348 Seconds |=========== | 56% Code I use is... print "Conversion: $converted_seconds/$total_time Seconds $progress_bar $converted_percentage%\n"; I am doing this in Linux using PHP(only I will use the app - so please excuse the language choice). So, the solution should work on the Linux platform - but if you have a solution that's cross platform, that would be preferable.

• Why do so many people dislike C++?

  - by General K

  Beginners and professional, on blogs, in forums and chatrooms - people say it everywhere: C++ oh dear god no The short form of the question: For what reason is C++ so widely disliked and people are horrified by the imagination of using it for some project? I have been using a lot of different languages, including C++ by now, and I can only say that I really like it. I'm far more horrified by Delphi than by C++. Actually, I find it's an almost perfect, compiled language! I've been doing a lot of different projects in C++ as well, ranging from 3D video games to webservers and emulators for old video game consoles. And I still do not see the problem everyone else seems to have with it!

• Scheme - What is wrong with my attempt to extend this declaration?

  - by CppLearner

  This is a homework question. Question My attempt (the whole file): http://pastebin.com/vt3Q3dqs If you search let var = exp1 in body, that's the function I need to extend according to the question. When I test the sample code above, I get an error apply-env: No binding for y (eval "let x = 30 in let x = -(x,1) y = -(x,2) in -(x,y)") ; The following is execution log The-next-two-lines-shows-var-and-exp1 (x) (#(struct:const-exp 30)) diff-exp #(struct:var-exp x) #(struct:const-exp 1) diff-exp #(struct:var-exp x) #(struct:const-exp 2) The-next-two-lines-shows-var-and-exp1 (x y) (#(struct:diff-exp #(struct:var-exp x) #(struct:const-exp 1)) #(struct:diff-exp #(struct:var-exp x) #(struct:const-exp 2))) diff-exp #(struct:var-exp x) #(struct:var-exp y) As you can see, when the interperter reads the last line -(x,y) it complains because there is no binding. What did I do wrong? I know this is really long language, but if anyone can kindly lead me to the right direction would be really really nice. Thank you!

• How is this problem usually solved without using sever-side scripting?

  - by cyggi

  Simple problem I have so far always solved via PHP: You have a site with header, menu, footer and content field. Header, menu and footer are usually the same for each page. How do you, without PHP or any other server-side language, have the header, menu and footer data exist only in one file? So that for example you don't have ten sites (like home.html, products.html, about.html, ..) all having a copy of the static header and menu in their html files. Now if you want to change the header you have to change ten files. I hope I made my question clear enough, if not please leave a comment :)

• Can I distort a bitmap image in Flash?

  - by drpepper

  Hi, what I would like to do is to take a loaded GIF file as a Bitmap, and then distort it by stretching and shrinking parts of it, so it would look like it got squished up against the screen. I'm pretty sure that there's no easy way in Flash to go beyond scaling and shearing, but I wonder if there might be some simple techniques to accomplish this kind of effect. By the way, I've also thought of pre-deforming the images in GIMP and saving them there, but I can't find a simple way to do it without learning their scripting language. Thanks for your help!

• "Inlining" (kind of) functions at runtime in C

  - by fortran

  Hi, I was thinking about a typical problem that is very JIT-able, but hard to approach with raw C. The scenario is setting up a series of function pointers that are going to be "composed" (as in maths function composition) once at runtime and then called lots and lots of times. Doing it the obvious way involves many virtual calls, that are expensive, and if there are enough nested functions to fill the CPU branch prediction table completely, then the performance with drop considerably. In a language like Lisp, I could probably process the code and substitute the "virtual" call by the actual contents of the functions and then call compile to have an optimized version, but that seems very hacky and error prone to do in C, and using C is a requirement for this problem ;-) So, do you know if there's a standard, portable and safe way to achieve this in C? Cheers

• Remove specified text from beginning of lines only if present (C#)

  - by Zach

  I have a textbox in which the user can edit text, in a scripting language. I've figured out how to let the user comment out lines in one click, but can't seem to figure out how to uncomment properly. For example, if the box has: Normal Text is here More normal text -- Commented text -- More commented text Normal Text again --Commented Text Again So, when the user selects any amount of text and decides to uncomment, the "--" is removed from the beginning of the lines that have it. The lines without the "--" should be unaffected. In short, I want an uncomment function that performs similar to the one in Visual Studio. Is there any way to accomplish this? Thanks

• Community based translating system

  - by mike

  Since we don't funds to hire translators for getting multiple languages translated we want the community to do the translation for us. Its a social network. I can't find any good open souce framework to auto do this. Thinking something like: User selects a language, system displays random sentences and user will translate it. Then other users can vote on how good it is. If it's 100 votes + with 95% yes then it becomes official. Site is in PHP. Any ideas?

• control.focus() after selectedIndexChanged

  - by kyle

  I need to focus on a textbox after an item has been selected from a dropdownlist. I've tried control.focus() and setfocus(). The last thing I've tried was Set_Focus(dtbEffectiveDate.ClientID) inside the SelectedIndexChanged method with the folowing method. Protected Sub Set_Focus(ByVal ControlName As String) Dim strScript As String strScript = "<script language=javascript> window.setTimeout(""" + ControlName + ".focus();"",0); </script>" RegisterStartupScript("focus", strScript) End Sub I'm out of answers so any help would be awesome.

• How to yield a single element from for loop in scala?

  - by Julio Faerman

  Much like this question: Functional code for looping with early exit Say the code is def findFirst[T](objects: List[T]):T = { for (obj <- objects) { if (expensiveFunc(obj) != null) return /*???*/ Some(obj) } None } How to yield a single element from a for loop like this in scala? I do not want to use find, as proposed in the original question, i am curious about if and how it could be implemented using the for loop. * UPDATE * First, thanks for all the comments, but i guess i was not clear in the question. I am shooting for something like this: val seven = for { x <- 1 to 10 if x == 7 } return x And that does not compile. The two errors are: - return outside method definition - method main has return statement; needs result type I know find() would be better in this case, i am just learning and exploring the language. And in a more complex case with several iterators, i think finding with for can actually be usefull. Thanks commenters, i'll start a bounty to make up for the bad posing of the question :)
