  • jQuery slide effect

    - by Ayrton
    Hi I'm looking for a slide effect for a navigation. But in my opinion the slide effect of jQuery is a little strange, or doesn't really fit my needs. The list items kind of appear but aren't animated (the container is only animated) when I apply the slideDown,slideUp,toggleSlide effect. I would like to have the list items animated as well. I've found an example of this: http://www.creative-exposure.co.uk/ If you someone could help me out, I would really appreciate it. yours truthfully

  • segfault during fclose()

    - by Hristo
    fclose() is causing a segfault. I have : char buffer[L_tmpnam]; char *pipeName = tmpnam(buffer); FILE *pipeFD = fopen(pipeName, "w"); // open for writing ... ... ... fclose(pipeFD); I don't do any file related stuff in the ... yet so that doesn't affect it. However, my MAIN process communicates with another process through shared memory where pipeName is stored; the other process fopen's this pipe for reading to communicated with MAIN. Any ideas why this is causing a segfault? Thanks, Hristo

  • Using python to play two sin tones at once

    - by Alex
    Im using python to a sine tone. the tone is based off the computers internal time in minutes, but id like to simultaneously play one based off the second for a harmonized or dualing sound. This is what I have so far can someone point me in the right direction. from struct import pack from math import sin, pi import time def au_file(name, freq, dur, vol): fout = open(name, 'wb') # header needs size, encoding=2, sampling_rate=8000, channel=1 fout.write('.snd' + pack('>5L', 24, 8*dur, 2, 8000, 1)) factor = 2 * pi * freq/8000 # write data for seg in range(8 * dur): # sine wave calculations sin_seg = sin(seg * factor) fout.write(pack('b', vol * 127 * sin_seg)) fout.close() t = time.strftime("%S", time.localtime()) ti = time.strftime("%M", time.localtime()) tis = float(t) tis = tis * 100 tim = float(ti) tim = tim * 100 if name == 'main': au_file(name='timeSound1.au', freq = tim, dur=1000, vol=1.0) import os os.startfile('timeSound1.au')

  • Are there disadvantages to using VARCHAR(MAX) in a table?

    - by Meiscooldude
    Here is my predicament. Basically, I need a column in a table to hold up an unknown length of characters. But I was curious if in Sql Server performance problems could arise using a VARCHAR(MAX) or NVARCHAR(MAX) in a column, such as: 'This time' I only need to store 3 characters and most of the time I only need to store 10 characters. But there is a small chances that It could be up to a couple thousand characters in that column, or even possibly a million, It is unpredictable. But, I can guarantee that it will not go over the 2GB limit. I was just curious if there are any performance issues, or possibly better ways of solving this problem where available.

  • How to convert an NSArray of NSManagedObjects to NSData

    - by carok
    Hi, I'm new to Objective C and was wondering if anyone can help me. I am using core data with a sqlite database to hold simple profile objects which have a name and a score attribute (both of which are of type NSString). What I want to do is fetch the profiles and store them in an NSData object, please see my code below: NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"GamerProfile" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]; NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"Name" ascending:YES]; NSArray *sortDecriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [fetchRequest setSortDescriptors:sortDecriptors]; [sortDescriptor release]; [sortDecriptors release]; NSError *error; NSArray *items = [self.managedObjectContext executeFetchRequest:fetchRequest error:&error]; NSData *data = [NSKeyedArchiver archivedDataWithRootObject:items]; [self SendData:data]; [fetchRequest release]; When I run the code I'm getting the error "Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[GamerProfile encodeWithCoder:]: unrecognized selector sent to instance 0x3f4b530'" I presume I have to add an encodeWithCoderClass to my core data NSManagedObject object (GamerProfile) but I'm not sure how to do this even after reading the documentation, My attempt at doing this is below. I'm not sure if I'm going along the right lines with this as get a warning stating "NSManagedObject" may not respond to '-encodeWithCoder'" I would really, really appreciate it if someone could point me in the right direction!! Thanks C Here is the code for my GamerProfile (CoreData NSManagedObject Object) with my attempt at adding an encodeWithCoder method... Header File #import <CoreData/CoreData.h> @interface GamerProfile : NSManagedObject <NSCoding> { } @property (nonatomic, retain) NSString * GamerScore; @property (nonatomic, retain) NSString * Name; - (void)encodeWithCoder:(NSCoder *)coder; @end Code File #import "GamerProfile.h" @implementation GamerProfile @dynamic GamerScore; @dynamic Name; - (void)encodeWithCoder:(NSCoder *)coder { [super encodeWithCoder:coder]; [coder encodeObject:GamerScore forKey:@"GamerScore"]; [coder encodeObject:Name forKey:@"Name"]; }

  • Why is it necessary to chmod o+r parent directory to fix 403 access forbidden error with Nginx and P

    - by davenolan
    This may be an Nginx wrinkle, or it may be because I don't understand Unix permissions. We're using Hudson CI to deploy our staging instance. So RAILS_ROOT is /var/lib/hudson/jobs/JOBNAME/workspace. Hudson runs as hudson user Nginx runs as www-data user hudson and nginx are both members of the www group root of my nginx conf points to RAILS_ROOT/public as per normal. RAILS_ROOT/config/environment.rb is owned by www-data (so Passenger runs as www-data) RAILS_ROOT and everything in it is owned by the www group and group has r/w/x permissions As it stood, Nginx threw 403 permission denied when requesting any url. error.log contained entries like this: public/index.html" is forbidden (13: Permission denied). These did not fix the or change the error (each with a stop/start of Ngnix): chmod 777 -R RAILS_ROOT chgrp www -R /var/lib/hudson I also tried Nginx as root, and passenger complained that it could not find config/environment (despite the path displayed on the error page being correct). The fix was to ensure everybody has read permissions on each directory in the heirachy. In this case chmod o+r /var/lib/hudson. But if the group has read permissions on the directory, and nginx is a member of the owner group of the directory, why was it necessary to allow everyone read permissions? Is there something have not grokked about permissions? $nginx -V nginx version: nginx/0.7.61 built by gcc 4.4.1 (Ubuntu 4.4.1-4ubuntu8) configure arguments: --prefix=/opt/nginx --add-module=/usr/lib/ruby/gems/1.8/gems/passenger-2.2.5/ext/nginx --with-http_ssl_module --with-pcre=~/src/pcre-8.00/ --with-http_stub_status_module $cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=9.10 DISTRIB_CODENAME=karmic DISTRIB_DESCRIPTION="Ubuntu 9.10"

  • IIS FTP server not working after purchase of SSL certificate

    - by Chris
    I've been connecting to my web server with active mode in FileZilla with no problems. Over the weekend, an SSL certificate was dropped into a folder that I access with FTP, and which contains files for the website. Now I am receiving a 425 error in active mode on the FTP root, so I can't really do anything but log in. In passive mode, I can connect and move around in the directory tree, but the connection seems shaky. Occasionally I'll time out, and I can't get access at all to the folder containing the SSL certificate. My question is how does the SSL certificate affect my FTP connection (if at all)? Does its presence demand the use of FTP over SSL? Note: As far as I know, the only change which occurred was the placement of the SSL certificate. Firewall settings, FTP client and server settings should all be the same as before, when everything was working.

  • Thesaurus software needed for Windows XP

    - by andygrunt
    Can anyone recommend (free) Thesaurus software for Windows XP (that isn't WordWeb)? It has to work with British English. I want to install standalone software that gives me easy access (right click, keyboard shortcut or something) to alternatives to the selected word when I'm writing, whether it's an email, a text doc in notepad, on an internet forum or whatever. I've tried WordWeb but found it pretty horrible - I want something that acts more like the Thesaurus in MS Word, giving a dozen or so decent alternatives to the selected word.

  • What's with all the mailing archives?

    - by Yuval
    When I google for certain questions, or problems I run into I would sometimes run into 'archive' sites - these sites contain forum questions or information from other sites that are extremely poorly formatted, and are copies of the well formatted original posts from various forums. An example of one of those sites in mail-archive.com and various similar sites. Can anybody explain to me why those sites exist and how come they don't get banned from Google (since all they have is copied content that is really poorly formatted by bots)? Thanks!

  • Eclipse CDT: cannot debug or terminate application

    - by Paul Lammertsma
    I have Eclipse set up fairly nicely to run the G++ compiler through Cygwin. Even the character encoding is set up correctly! There still seems to be something wrong with my configuration: I can't debug. The pause button in the debug view is simply disabled, and no threads appear in my application tree. It seems that gdb is simply not communicating with Eclipse. Presently, I have the debug settings as follows: Debugger: "Cygwin gdb Debugger" GDB debugger: gdb GDB command file: .gdbinit Protocol: Default I should mention here that I have no idea what .gdbinit does; in my project it is merely an empty file. What is wrong with my configuration? Debugging When attempting to terminate the application in debug mode, Eclipse displays the following error: Target request failed: failed to interrupt. I can't kill the process, either; I have to kill its parent gdb.exe, which in turn kills my application. Running When running it normally, a bunch of kill.exes are called, doing nothing, while Eclipse displays the following error: Terminate failed. I can kill FaceDetector.exe from the task manager. Process Explorer This is what it looks like in Process Explorer (debugging left, running right):

  • Are there Python ORMs out there that support multiple independent databases concurrently in use?

    - by sdt
    I'm writing an application in Python where I wish to use sqlite as the backing store for documents edited by the app, with documents generally living in memory, but being saved to disk-based databases when the application saves. Ideally I'd like to use something like an ORM to make access to the data from my Python application code simple. Unfortunately it seems like the majority of Python ORMs, including SQLAlchemy, SQLObject, Django, and Storm, associate the database connection (or engine or whatever) with the classes representing table data, rather than instances of those classes. This restricts these ORMs to working with a single database connection across all instances. Since I'd like to support having multiple documents open simultaneously, this isn't going to work for me. Are there any ORMs out there that support this usage model in Python? Bazaar seems to support this, but it's quite out of date, and at first glance appears to have some other shortcomings. Thanks for any suggestions!

  • Pass a JSON array to a WCF web service

    - by Tawani
    I am trying to pass a JSON array to a WCF service. But it doesn't seem to work. I actually pulled an array [GetStudents] out the service and sent the exact same array back to the service [SaveStudents] and nothing (empty array) was received. The JSON array is of the format: [ {"Name":"John","Age":12}, {"Name":"Jane","Age":11}, {"Name":"Bill","Age":12} ] And the contracts are of the following format: //Contracts [DataContract] public class Student{ [DataMember]public string Name { get; set; } [DataMember]public int Age{ get; set; } } [CollectionDataContract(Namespace = "")] public class Students : List<Student> { [DataMember]public Endorsements() { } [DataMember]public Endorsements(IEnumerable<Student> source) : base(source) { } } //Operations public Students GetStudents() { var result = new Students(); result.Add(new Student(){Name="John",12}); result.Add(new Student(){Name="Jane",11}); result.Add(new Student(){Name="Bill",12}); return result; } //Operations public void SaveStudents(Students list) { Console.WriteLine(list.Count); //It always returns zero } It there a particular way to send an array to a WCF REST service?

  • Getting the final value to this MySQL query...

    - by Jack W-H
    I've got my database set up with three tables - code, tags, and code_tags for tagging posts. This will be the SQL query processed when a post is submitted. Each tag is sliced up by PHP and individually inserted using these queries. INSERT IGNORE INTO tags (tag) VALUES ('$tags[1]'); SELECT tags.id FROM tags WHERE tag = '$tags[1]' ORDER BY id DESC LIMIT 1; INSERT INTO code_tags (code_id, tag_id) VALUES ($codeid, WHAT_GOES_HERE?) The WHAT_GOES_HERE? value at the end is what I need to know. It needs to be the ID of the tag that the second query fetched. How can I put that ID into the third query? I hope I explained that correctly. I'll rephrase if necessary.

  • C++ STL Map vs Vector speed

    - by sub
    In the interpreter for my experimental programming language I have a symbol table. Each symbol consists of a name and a value (the value can be e.g.: of type string, int, function, etc.). At first I represented the table with a vector and iterated through the symbols checking if the given symbol name fitted. Then I though using a map, in my case map<string,symbol>, would be better than iterating through the vector all the time but: It's a bit hard to explain this part but I'll try. If a variable is retrieved the first time in a program in my language, of course its position in the symbol table has to be found (using vector now). If I would iterate through the vector every time the line gets executed (think of a loop), it would be terribly slow (as it currently is, nearly as slow as microsoft's batch). So I could use a map to retrieve the variable: SymbolTable[ myVar.Name ] But think of the following: If the variable, still using vector, is found the first time, I can store its exact integer position in the vector with it. That means: The next time it is needed, my interpreter knows that it has been "cached" and doesn't search the symbol table for it but does something like SymbolTable.at( myVar.CachedPosition ). Now my (rather hard?) question: Should I use a vector for the symbol table together with caching the position of the variable in the vector? Should I rather use a map? Why? How fast is the [] operator? Should I use something completely different?

  • as3 formatting a textfield

    - by duckofrubber
    Hi, I'm dynamically creating textfields in as3, and formatting them with the TextFormat class. I'm having some issues though with selecting the exact "style" of font to apply to the textfields. My code so far looks like: formatT = new TextFormat( ); formatT.bold = false; formatT.color = 0x000000; formatT.font = "TradeGothic"; formatT.size = 16; var textItem = new TextField(); textItem.text = "foobar"; textItem.setTextFormat(formatT); addChild(textItem); This works ("Trade Gothic" is applied to the enclosed text), however I can't figure out how to apply a specific style of "Trade Gothic", for instance "Light Oblique". Is there some way that I can specify this using the TextFormat class? Thanks.

  • [ASP.NET] Change CulturalInfo after button click

    - by Bart
    Hello, i have multilingual asp.net site. there is masterpage and default.aspx in masterpage i put two buttons one to click when i want to change the language to english, second for polish. I want to change the language after click on these buttons (and all changes should appear automatically on the page) here is a code for both: protected void EnglishButton_Click(object sender, ImageClickEventArgs e) { string selectedLanguage = "en-US"; //Sets the cookie that is to be used by InitializeCulture() in content page HttpCookie cookie = new HttpCookie("CultureInfo"); cookie.Value = selectedLanguage; Response.Cookies.Add(cookie); Server.Transfer(Request.Path); } protected void PolishButton_Click(object sender, ImageClickEventArgs e) { string selectedLanguage = "pl-PL"; //Sets the cookie that is to be used by InitializeCulture() in content page HttpCookie cookie = new HttpCookie("CultureInfo"); cookie.Value = selectedLanguage; Response.Cookies.Add(cookie); Server.Transfer(Request.Path); } in default.aspx.cs i have InitializeCulture(): protected override void InitializeCulture() { HttpCookie cookie = Request.Cookies["CultureInfo"]; // if there is some value in cookie if (cookie != null && cookie.Value != null) { Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(cookie.Value); Thread.CurrentThread.CurrentUICulture = new CultureInfo(cookie.Value); } else // if none value has been sent by cookie, set default language { Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture("pl-PL"); Thread.CurrentThread.CurrentUICulture = new CultureInfo("pl-PL"); } base.InitializeCulture(); } i added resource files and in one label i show actual culture: Welcome.Text = "Culture: " + System.Globalization.CultureInfo.CurrentCulture.ToString(); the problem is that when i run this app and click e.g. english button (default language is polish), there is no effect. if i click it second time or press F5, the changes are applies and in the label is Culture: en-US. the same happens if i want to change language back to polish (it works after second click (or one click and refresh)). What am i doing wrong? Regards, Bart

  • Ideas on simulating webservices for local automated testing.

    - by novice123
    I am testing an app, which talks to different webservices over the internet. For my automated testing, I don't want to go over the network. To achieve this, I need to simulate the webservice on my machine using another app. My initial thought is to record all the requests and responses between client and webservice, and then just write a simulation app which replays these responses. The disadvantage here is that everytime the webservice protocol changes a bit, I have to modify all my recorded resposnes. so I am looking to see if there are more elegant solutions. have anyone solved a similar problem? any thoughts, suggestion are appreciated.
