• PerformancePoint dashboard permissions problem in MOSS

  - by Nathan DeWitt

  I have a PerformancePoint dashboard running in MOSS 2007 portal. The dashboard consists of one SSRS 2005 report, running in SharePoint Integrated mode. NT Authority\Authenticated Users have read permissions to the report library containing the SSRS report, the dashboard, and the report library containing the dashboard. Users that attempt to access the dashboard receive the following error message: The permissions granted to user 'DOMAIN\firstname.lastname' are insufficient for performing this operation. (rsAccessDenied) Users that then click on the direct link to the report in MOSS will see the report with no problem. Subsequent visits to the dashboard show the report with no problem. The report is using a data source that is located one folder up from the report location. The report has been updated to point to the correct shared data source after deployment. Both the report and the data source have been published. The data source is using stored credentials, with a domain service account that has been set to Use as Windows credentials. This service account is serving other reports in other areas with no problem. Edit: Ok, I've gotten a lot more information on this problem. The request is never actually being made to the data source. The user comes in to the dashboard and requests a report for the first time using their kerberos token identifying themselves. The report looks in the Report Server database and finds that they are not listed in the users table and generates this rsAccessDenied error. Once they view the report directly their name is in this table and they never have the problem again. Unfortunately, removing the user from the Users table in the RS database doesn't actually cause this error to happen again. Everything I've read says that when you run a Report Server in MOSS integrated mode all your permissions are handled at the MOSS report library level, and all Auth users have permissions to the report library, as stated earlier. Any ideas?

• Is this a good approach to address double-base64-encoding?

  - by Freiheit

  My software understands attachments, like PNGs attached to user records. These attachments are usually sent in from outside sources as a Base64 encoded string. The database stores whatever data it is given, Base64 encoded or not. When I serve up the attachment for download I do this: if (Base64.isBase64(data)) { data = Base64.decodeBase64(data); } There is a potential for data that is double encoded. For instance the sender of a message had base64 encoded data, then encoded it again when building the message to send to me. I think the following code would address that circumstance: while (Base64.isBase64(data)) { data = Base64.decodeBase64(data); } So if data is encoded multiple times, it would be decoded until its in its 'raw' state and then served up for download. Is this approach an acceptable way to address that problem? Ideally some sort of checking could happen at the edge when I receive attachment data, but that will take more time. This looping seems to be a faster way to do it. The 'Base64' library is Apache Commons: http://commons.apache.org/codec/apidocs/org/apache/commons/codec/binary/Base64.html I trust it to properly identify Base64 encoded data.

• C# TCP Async EndReceive() throws InvalidOperationException ONLY on Windows XP 32-bit

  - by James Farmer

  I have a simple C# Async Client using a .NET socket that waits for timed messages from a local Java server used for automating commands. The messages come in asynchronously and is written to a ring buffer. This implementation seems to work fine on Windows Vista/7/8 and OSX, but will randomly throw this exception while it's receiving a message from the local Java server: Unhandled Exception: System.InvalidOperationException: EndReceive can only be called once for each asynchronous operation.     at System.Net.Sockets.Socket.EndReceive(IAsyncResult asyncResult, SocketError& errorCode)     at System.Net.Sockets.Socket.EndReceive(IAsyncResult asyncResult)     at SocketTest.Controller.RecvAsyncCallback(IAsyncResult ar)     at System.Net.LazyAsyncResult.Complete(IntPtr userToken)     ... I've looked online for this error, but have found nothing really helpful. This is the code where it seems to break: /// <summary> /// Callback to receive socket data /// </summary> /// <param name="ar">AsyncResult to pass to End</param> private void RecvAsyncCallback(IAsyncResult ar) { // The exception will randomly happen on this call int bytes = _socket.EndReceive(_recvAsyncResult); // check for connection closed if (bytes == 0) { return; } _ringBuffer.Write(_buffer, 0, bytes); // Checks buffer CheckBuffer(); _recvAsyncResult = _sock.BeginReceive(_buffer, 0, _buffer.Length, SocketFlags.None, RecvAsyncCallback, null); } The error doesn't happen on any particular moment except in the middle of receiving a message. The message itself can be any length for this to happen, and the exception can happen right away, or sometimes even up to a minute of perfect communication. I'm pretty new with sockets and network communication, and I feel I might be missing something here. I've tested on at least 8 different computers, and the only similarity with the computers that throw this exception is that their OS is Windows XP 32-bit.

• Adding a UITapGestureRecognizer to a view then removing seems to short circuit button events

  - by heymon

  In the code below I am popping up a ImageView as the result of a users touchUpInside on a simple info button. There are other buttons on the view. To dismiss the info I added a UITapGestureRecognizer to my controllers view, and hide the view when the tap is detected. If I don't remove the tapGestureRecognizer, the action is called every time some. Even when I do remove the gesture action, no bottons receive touchUpInside events once this gesture recognizer is added. Why? Code from my MainViewController (void) dismissInfo: (UITapGestureRecognizer *)gesture { [kInfoView setHidden: YES]; [gesture removeTarget: self action: NULL]; } (IBAction) displayInfo { CGRect startFrame = CGRectMake(725, 25, 0, 0), origFrame; CGFloat yCenter = [kInfoView frame].size.height/2 + 200; CGPoint startCenter = CGPointMake(724, 25), displayCenter = CGPointMake(384, yCenter); UITapGestureRecognizer *g = [[UITapGestureRecognizer alloc] initWithTarget: self action: @selector(dismissInfo:)]; [self.view addGestureRecognizer: g]; origFrame = [kInfoView frame]; [kInfoView setCenter: startCenter]; [kInfoView setHidden: NO]; [kInfoView setFrame: startFrame]; [UIView beginAnimations: @"info" context: nil]; [UIView setAnimationDuration: .5]; [UIView setAnimationDelegate: self]; [kInfoView setFrame: origFrame]; [kInfoView setCenter: displayCenter]; [UIView commitAnimations]; }

• Sync Vs. Async Sockets Performance in .NET

  - by Michael Covelli

  Everything that I read about sockets in .NET says that the asynchronous pattern gives better performance (especially with the new SocketAsyncEventArgs which saves on the allocation). I think this makes sense if we're talking about a server with many client connections where its not possible to allocate one thread per connection. Then I can see the advantage of using the ThreadPool threads and getting async callbacks on them. But in my app, I'm the client and I just need to listen to one server sending market tick data over one tcp connection. Right now, I create a single thread, set the priority to Highest, and call Socket.Receive() with it. My thread blocks on this call and wakes up once new data arrives. If I were to switch this to an async pattern so that I get a callback when there's new data, I see two issues The threadpool threads will have default priority so it seems they will be strictly worse than my own thread which has Highest priority. I'll still have to send everything through a single thread at some point. Say that I get N callbacks at almost the same time on N different threadpool threads notifying me that there's new data. The N byte arrays that they deliver can't be processed on the threadpool threads because there's no guarantee that they represent N unique market data messages because TCP is stream based. I'll have to lock and put the bytes into an array anyway and signal some other thread that can process what's in the array. So I'm not sure what having N threadpool threads is buying me. Am I thinking about this wrong? Is there a reason to use the Async patter in my specific case of one client connected to one server?

• Ajax call to parent window after form submission

  - by David

  Hi all, Pardon the complicated title. Here's my situation: I'm working on a Grails app, and using jQuery for some of the more complex UI stuff. The way the system is set up, I have an item, which can have various files (user-supplied) associated with it. On my Item/show view, there is a link to add a file. This link pops up a jQuery modal dialog, which displays my file upload form (a remote .gsp). So, the user selects the file and enters a comment, and when the form is submitted, the dialog gets closed, and the list of files on the Item/show view is refreshed. I was initially accomplishing this by adding onclick="javascript:window.parent.$('#myDialog').dialog('close');" to my submit button. This worked fine, but when submitting some larger files, I end up with a race condition where the dialog closes and the file list is refreshed before the new file is saved, and so the list of files is out of date (the file still gets saved properly). So my question is, what is the best way to ensure that the dialog is not closed until after the form submit operation completes? I've tried using the <g:formRemote tag in Grails, and closing the dialog in the "after" attribute (according to the Grails docs, the script is called after form submission), but I receive an error (taken from FireBug) stating that window.parent.$('#myDialog').dialog is not a function Is this a simple JavaScript/Grails syntax issue that I'm missing here, or am I going about this entirely wrong? Thanks so much for your time and assistance!

• Google Analytics API Authentication Speedup

  - by Paulo

  I'm using a Google Analytics API Class in PHP made by Doug Tan to retrieve Analytics data from a specific profile. Check the url here: http://code.google.com/intl/nl/apis/analytics/docs/gdata/gdataArticlesCode.html When you create a new instance of the class you can add the profile id, your google account + password, a daterange and whatever dimensions and metrics you want to pick up from analytics. For example i want to see how many people visited my website from different country's in 2009. //make a new instance from the class $ga = new GoogleAnalytics($email,$password); //website profile example id $ga->setProfile('ga:4329539'); //date range $ga->setDateRange('2010-02-01','2010-03-08'); //array to receive data from metrics and dimensions $array = $ga->getReport( array('dimensions'=>('ga:country'), 'metrics'=>('ga:visits'), 'sort'=>'-ga:visits' ) ); Now you know how this API class works, i'd like to adress my problem. Speed. It takes alot of time to retrieve multiple types of data from the analytics database, especially if you're building different arrays with different metrics/dimensions. How can i speed up this process? Is it possible to store all the possible data in a cache so i am able to retrieve the data without loading it over and over again?

• Java/BlackBerry build error overriding too many classes

  - by behrk2

  Hey everyone, Has anyone ever heard of overriding too many classes in Java? Perhaps this issue is just related to BlackBerry development, but I was wondering if it is an issue in Java, too. Let's say I have the following: LabelField lblTitle = new LabelField(title) { protected void paint(Graphics graphics) { graphics.setColor(0x00FFFFFF); graphics.clear(); super.paint(graphics); } }; LabelField lblSubTitle = new LabelField(releaseYear + ", " + rating) { protected void paint(Graphics graphics) { graphics.setColor(0x00FFFFFF); graphics.clear(); super.paint(graphics); } }; This code works. However, I've noticed that by overriding the paint() method multiple times in many different classes throughout my project, I receive the error: I/O Error: Cannot run program "jar": CreateProcess error=2, The system cannot find the file specified My only solution thus far is to clean up my GUI code...minimize it and reuse it. Perhaps its good that this happened so I can be less careless about creating GUI code all over my classes. Anyways, I was just wondering if anyone has heard of this before. If you are interested in reading more about the issue I have been facing, check out the following link: BlackBerry Java Development Forums

• How to handle custom Java exception in Flex app.

  - by mico

  Hello, we are using BlazeDS as a proxy between Flex and Java. The approach is the same as in (http://www.flexpasta.com/index.php/2008/05/16/exception-handling-with-blazeds-and-flex/) Java exception declaration: public class FlexException extends RuntimeException { private String name = 'John'; public FlexException(String message) { super(message); } public String getName() { return name; } } Then, we are throwing it: public void testMethod(String str) throws Exception { throw new FlexException("Custom exception"); } Flex part: private function faultHandler(event:FaultEvent):void { var errorMessage:ErrorMessage = event.message as ErrorMessage; trace("error++"); } and remote object is instantiated here: <mx:RemoteObject id="mySample" destination="mySample" channelSet="{cs1}" fault="faultHandler(event)" /> But in event.fault I get "Server.Processing" and event.faultString equals "There was an unhandled failure on the server. Custom exception" How can I receive the data is specified in exception props ? BlazeDS log is similar to the log that was mentioned in the comment [BlazeDS] 11:28:13.906 [DEBUG] Serializing AMF/HTTP response Version: 3 (Message #0 targetURI=/2/onStatus, responseUR|-) (Typed Object #0 ‘flex.messaging.messages.ErrorMessage’) headers = (Object #1) rootCause = null body = null correlationId = “2F1126D7-5658-BE40-E27C-7B43F3C5DCDD” faultDetail = null faultString = “Login required before authorization can proceed.” clientId = “C4F0E77C-3208-ECDD-1497-B8D070884830? timeToLive = 0.0 destination = “books” timestamp = 1.204658893906E12 extendedData = null faultCode = “Client.Authentication” messageId = “C4F0E77C-321E-6FCE-E17D-D9F1C16600A8? So the quesion is why rootClause is null? How can I get that Exception object not just a string 'Custom exception'?

• How to show AdMob ads in real iPhone device?

  - by iPhoney

  I want to integrate AdMob ads in my iPhone app. I'm using IB way to add the view and follow AdMob's pdf guide: 1. Add AdMob group(AdMobView.h,AdMobDelegateProtocol.h,libAdMob.a) 2. Add required frameworks(AudioToolbox,MediaPlayer,MessageUI,QuartzCore) 3. Add TouchJSON group 4. Add IBSupport group(AdViewController.h,AdViewController.m) 5. Add a 320*48 UIView in IB, add NSObject and change its class to AdViewController, link AdViewController's view to the 320*48 UIView and link AdViewController's viewController to current view controller. Now the iPhone simulator can show ads from AdMob, but when I test it on real device, I get the error "AdMob: Did fail to receive ad". I've tried to add test device's UDID to testDevices array, but still get the same error. - (NSArray *)testDevices { return [NSArray arrayWithObjects: ADMOB_SIMULATOR_ID, DEVICE_UDID, nil]; } Is there any problem in the above steps? Does anybody know why can't I get the ads in real device? By the way, what should be changed to build for real for-sale app, not just for test?

• Is there any framework for rich web clients on top of html/css?

  - by iamgopal

  Some RAD tools like openobject use rich web clients. I.e. their client side code reside inside the browser and they talk to the server via xml-rpc or json-rpc only and change the view accordingly, all the javascript and css are transferred only once. Such rich web clients would increase the productivity in enterprise class web application that have lots of processes and forms etc. I would like to use such a rich web client inside my own application. I tried to search but found only openerp-web, which is tightly integrated to its server. Is there any other rich web client framework available? if not, is there any design detail I can look into to create my own? Thanks. Edit: Browser is a client which uses http and similar protocols to talks to web server which serve pages that the client displays. Rich web client is a client which sits on top of Browser which talks to the server, send data, receive data and information about How to update the view etc and do it. Similar to Vaadin, such rich web client will eliminate any code requirement on client side and and all the coding will be done on server side. Belows are such thin clients. pjax ( jquery ) vaadin ( java ) openobject web client ( python ) nagare ( python ) seaside ( smalltalk ) p4a ( php ) this are all such clients that once properly setup will allow to code on only on sever and still provide great ajax like experience.

• Sending custom PyQt signals?

  - by Enfors

  I'm practicing PyQt and (Q)threads by making a simple Twitter client. I have two Qthreads. Main/GUI thread. Twitter fetch thread - fetches data from Twitter every X minutes. So, every X minutes my Twitter thread downloads a new set of status updates (a Python list). I want to hand this list over to the Main/GUI thread, so that it can update the window with these statuses. I'm assuming that I should be using the signal / slot system to transfer the "statuses" Python list from the Twitter thread, to the Main/GUI thread. So, my question is twofold: How do I send the statuses from the Twitter thread? How do I receive them in the Main/GUI thread? As far as I can tell, PyQt can by default only send PyQt-objects via signals / slots. I think I'm supposed to somehow register a custom signal which I can then send, but the documentation on this that I've found is very unclear to a newbie like me. I have a PyQt book on order, but it won't arrive in another week, and I don't want to wait until then. :-) I'm using PyQt 4.6-1 on Ubuntu Update: This is an excert from the code that doesn't work. First, I try to "connect" the signal ("newStatuses", a name I just made up) to the function self.update_tweet_list in the Main/GUI thread: QtCore.QObject.connect(self.twit_in, QtCore.SIGNAL("newStatuses (statuses)"), self.update_tweet_list) Then, in the Twitter thread, I do this: self.emit(SIGNAL("newStatuses (statuses)"), statuses) When this line is called, I get the following message: QObject::connect: Cannot queue arguments of type 'statuses' (Make sure 'statuses' is registered using qRegisterMetaType().) I did a search for qRegisterMetaType() but I didn't find anything relating to Python that I could understand.

• There's a black hole in my server (TcpClient, TcpListener)

  - by Matías

  Hi, I'm trying to build a server that will receive files sent by clients over a network. If the client decides to send one file at a time, there's no problem, I get the file as I expected, but if it tries to send more than one I only get the first one. Here's the server code: I'm using one Thread per connected client public void ProcessClients() { while (IsListening) { ClientHandler clientHandler = new ClientHandler(listener.AcceptTcpClient()); Thread thread = new Thread(new ThreadStart(clientHandler.Process)); thread.Start(); } } The following code is part of ClientHandler class public void Process() { while (client.Connected) { using (MemoryStream memStream = new MemoryStream()) { int read; while ((read = client.GetStream().Read(buffer, 0, buffer.Length)) > 0) { memStream.Write(buffer, 0, read); } if (memStream.Length > 0) { Packet receivedPacket = (Packet)Tools.Deserialize(memStream.ToArray()); File.WriteAllBytes(Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory), Guid.NewGuid() + receivedPacket.Filename), receivedPacket.Content); } } } } On the first iteration I get the first file sent, but after it I don't get anything. I've tried using a Thread.Sleep(1000) at the end of every iteration without any luck. On the other side I have this code (for clients) . . client.Connect(); foreach (var oneFilename in fileList) client.Upload(oneFilename); client.Disconnect(); . . The method Upload: public void Upload(string filename) { FileInfo fileInfo = new FileInfo(filename); Packet packet = new Packet() { Filename = fileInfo.Name, Content = File.ReadAllBytes(filename) }; byte[] serializedPacket = Tools.Serialize(packet); netStream.Write(serializedPacket, 0, serializedPacket.Length); netStream.Flush(); } netStream (NetworkStream) is opened on Connect method, and closed on Disconnect. Where's the black hole? Can I send multiple objects as I'm trying to do? Thanks for your time.

• Using git submodules in a git-svn project

  - by Matthias

  In our git-svn managed project, we have 3 upstream projects that are all kept in native git repositories on GitHub. Since the source code of those upstream projects is under our control and changes frequently, our current solution, namely re-deploying the build artifacts to the super-project everytime we change something is quite cumbersome. What I'd like to have is this: parent project (git-svn): --> submodule 1 (git) --> submodule 2 (git) --> submodule 3 (git) That way, the source code for submodules 1-3 is compiled along with the sources for the super project, but I can push changes to submodules separately. The question is: what happens when I git svn dcommit on the parent project? Does this even work? UPDATE Hm, I just set up a simple project structure, trying to resemble this scenario, and I receive this error message when trying to dcommit on the superproject: a0301b11f3544a1e71067ff270eded65e4c8afbd doesn't exist in the repository at /opt/local/libexec/git-core/git-svn line 4775 Failed to read object a0301b11f3544a1e71067ff270eded65e4c8afbd at /opt/local/libexec/git-core/git-svn line 574 Any ideas/suggestions?

• How to call a C# DLL from InstallerClass overrides?

  - by simpleton

  I have a setup and deployment project. In it I have an Installer.cs class, created from the basic Installer Class template. In the Install override, I have this code taken from http://msdn.microsoft.com/en-us/library/d9k65z2d.aspx. public override void Install(IDictionary stateSaver) { base.Install(stateSaver); System.Diagnostics.Process.Start("http://www.microsoft.com"); } Everything works when I install the application, but the problem arises when I try to call anything from an external C# class library that I also wrote. Example: public override void Install(IDictionary stateSaver) { base.Install(stateSaver); System.Diagnostics.Process.Start("http://www.microsoft.com"); MyLibrary.SomeMethod(); } The problem is, I don't believe the library call is actually happening. I tagged the entire process line by line, with EventLog.WriteEvent()s, and each line in the Install override is seemlingly 'hit', putting entries in the event log, but I do not receive any exceptions for the library call SomeMethod(), yet the EventLog entries and other actions inside SomeMethod() are never created nor any of its actions taken. Any ideas?

• WCF - remote service without using IIS - base address?

  - by Mark Pim

  I'm trying to get my head around the addressing of WCF services. We have a client-server setup where the server occasionally (maybe once a day) needs to push data to each client. I want to have a lightweight WCF listener service on each client hosted in an NT service to receive that data. We already have such an NT service setup hosting some local WCF services for other tasks so the overhead of this is minimal. Because of existing legacy code on the server I believe the service needs to be exposed as ASMX and use basicHttpBinding to allow it to connect. Each client is registered on the server by the user (they need to configure them individually) so discovery is not the issue. My question is, how does the addressing work? I imagine the user entering the client's address on the server in the form http://0.0.0.0/MyService or even http://hostname/MyService If so, how do I configure the client service in its App.config? Do I use localhost? If not then what is the reccommended way of exposing the service to the server? Note: I don't want to host in IIS as that adds extra requirements to the hardware required for the client. The clients will be almost certainly located on LANs, not over the public internet

• LinkedIn API returning extra/incorrect login prompt

  - by Paul Osetinsky

  I have a Rails application running the omniauth-linkedin gem and linkedin gem (essentialy an API wrapper). When a user logs in, they receive a primary login prompt that displays to them the correct scopes (FULL PROFILE and EMAIL ADDRESS), as below: However, after they log in, they get another login prompt that should not come up, and that ignores the initial scope request. It tells them that LinkedIN is only requesting their PROFILE OVERVIEW, which is incorrect: The problem must lie in my auth_controller, and I think it has do to with the url that is created in one of the authentication stages (definitely right after the user enters their LinkedIn authentication credentials). Here is my auth_controller: require 'linkedin' class AuthController < ApplicationController def auth client = LinkedIn::Client.new(ENV['LINKEDIN_KEY'], ENV['LINKEDIN_SECRET']) request_token = client.request_token(:oauth_callback => "http://#{request.host_with_port}/callback") session[:rtoken] = request_token.token session[:rsecret] = request_token.secret redirect_to client.request_token.authorize_url end def callback client = LinkedIn::Client.new(ENV['LINKEDIN_KEY'], ENV['LINKEDIN_SECRET']) if session[:atoken].nil? pin = params[:oauth_verifier] atoken, asecret = client.authorize_from_request(session[:rtoken], session[:rsecret], pin) session[:atoken] = atoken session[:asecret] = asecret @user = current_user @user.uid = client.profile(:fields => ["id"]).id flash.now[:success] = 'Signed in with LinkedIn.' else client.authorize_from_access(session[:atoken], session[:asecret]) @user.uid = client.profile(:fields => ["id"]).id flash.now[:success] = 'Signed in with LinkedIn.' end @user = current_user @user.save redirect_to current_user end end Just in case, here is my omniauth.rb file that states the scopes I am requesting for my application: Rails.application.config.middleware.use OmniAuth::Builder do provider :linkedin, ENV['LINKEDIN_KEY'], ENV['LINKEDIN_SECRET'], :scope => 'r_fullprofile r_emailaddress', :fields => ['id', 'email-address', 'first-name', 'last-name', 'headline', 'industry', 'picture-url', 'public-profile-url', 'location', 'positions', 'educations'] end Can't figure out how to get rid of that second unnecessary and misleading prompt from LinkedIn and would appreciate any guidance! Thank you.

• Zend: How to authenticate using OpenId on local server.

  - by NAVEED

  I am using zend framework. Now I want to authenticate users with other already registered accounts using RPX. I am following the 3 steps as described at RPX site: 1- Get the Widget 2- Receive Tokens 3- Choose Providers I created a controller(person) and action(signin) to show widget and my own signin form. When following action (http://test.dev/#person/personsignin) is called then my own login form and widget is shown successfully. # is used in above URL for AJAX indication. public function personsigninAction() { $this->view->jsonEncoded = true; // Person Signin Form $PersonSigninForm = new Form_PersonSignin(); $this->view->PersonSigninForm = $PersonSigninForm; $this->view->PersonSigninForm->setAction( $this->view->url() ); $request = $this->getRequest(); if ( $request->isPost() ) { } } There are two problems while login using openid widget: When I am authenticated from outside(for example: Yahoo) then I am redirected to http://test.dev, therefor indexAction in called in indexController and home page is shown. I want to redirect to http://test.dev/#person/personsignin after authentication and want to set session in isPost() condition of personsigninAction() (described above). For now I consider indexAction to be called when outside authentication is done. Now I posted the code from http://gist.github.com/291396 in indexAction to follow step 3 mentioned above. But it is giving me following error: An error occured: Invalid parameter: apiKey Am I using the right way to use this. This is my very first attempt to this stuff. Can someone tell me the exact steps using my above actions? Thanks.

• How do I get the F1-F12 keys to switch screens in gnu screen in cygwin when connecting via SSH?

  - by Mikey

  I'm connecting to a desktop running cygwin via SSH from the terminal app in Mac OS X. I have already started screen on the cygwin side and can connect to it over the SSH session. Furthermore, I have the following in the .screenrc file: bindkey -k k1 select 1 # F1 = screen 1 bindkey -k k2 select 2 # F2 = screen 2 bindkey -k k3 select 3 # F3 = screen 3 bindkey -k k4 select 4 # F4 = screen 4 bindkey -k k5 select 5 # F5 = screen 5 bindkey -k k6 select 6 # F6 = screen 6 bindkey -k k7 select 7 # F7 = screen 7 bindkey -k k8 select 8 # F8 = screen 8 bindkey -k k9 select 9 # F9 = screen 9 bindkey -k F1 prev # F11 = prev bindkey -k F2 next # F12 = next However, when I start multiple windows in screen and attempt to switch between them via the function keys, all I get is a beep. I have tried various settings for $TERM (e.g. ansi, cygwin, xterm-color, vt100) and they don't really seem to affect anything. I have verified that the terminal app is in fact sending the escape sequence for the function key that I'm expecting and that my bash shell (running inside screen) is receiving it. For example, for F1, it sends the following (hexdump is a perl script I wrote that takes STDIN in binmode and outputs it as a hexadecimal/ascii dump): % hexdump [press F1 and then hit ^D to terminate input] 00000000: 1b4f50 .OP If things were working correctly, I don't think bash should receive the escape sequence because screen should have caught it and turned it into a command. How do I get the function keys to work?

• Mysql german accents not-sensitive search in full-text searches

  - by lukaszsadowski

  Let`s have a example hotels table: CREATE TABLE `hotels` ( `HotelNo` varchar(4) character set latin1 NOT NULL default '0000', `Hotel` varchar(80) character set latin1 NOT NULL default '', `City` varchar(100) character set latin1 default NULL, `CityFR` varchar(100) character set latin1 default NULL, `Region` varchar(50) character set latin1 default NULL, `RegionFR` varchar(100) character set latin1 default NULL, `Country` varchar(50) character set latin1 default NULL, `CountryFR` varchar(50) character set latin1 default NULL, `HotelText` text character set latin1, `HotelTextFR` text character set latin1, `tagsforsearch` text character set latin1, `tagsforsearchFR` text character set latin1, PRIMARY KEY (`HotelNo`), FULLTEXT KEY `fulltextHotelSearch` (`HotelNo`,`Hotel`,`City`,`CityFR`,`Region`,`RegionFR`,`Country`,`CountryFR`,`HotelText`,`HotelTextFR`,`tagsforsearch`,`tagsforsearchFR`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 COLLATE=latin1_german1_ci; In this table for example we have only one hotel with Region name = "Graubünden" (please note umlaut ü character) And now I want to achieve same search match for phrases: 'graubunden' and 'graubünden' This is simple with use of MySql built in collations in regular searches as follows: SELECT * FROM `hotels` WHERE `Region` LIKE CONVERT(_utf8 '%graubunden%' USING latin1) COLLATE latin1_german1_ci This works fine for 'graubunden' and 'graubünden' and as a result I receive proper result, but problem is when we make MySQL full text search Whats wrong with this SQL statement?: SELECT * FROM hotels WHERE MATCH (`HotelNo`,`Hotel`,`Address`,`City`,`CityFR`,`Region`,`RegionFR`,`Country`,`CountryFR`, `HotelText`, `HotelTextFR`, `tagsforsearch`, `tagsforsearchFR`) AGAINST( CONVERT('+graubunden' USING latin1) COLLATE latin1_german1_ci IN BOOLEAN MODE) ORDER BY Country ASC, Region ASC, City ASC This doesn`t return any result. Any ideas where the dog is buried ?

• Display XML diferent in JSF (using XSLT or some another suggestion)

  - by Milan

  Hello everybody! At runtime I receive xml document and I want to display it somehow different in JSF. For example: This: <invoker.ArrayOfDictionary> <dictionary> <invoker.Dictionary> <id>gcide</id> <name>The Collaborative International Dictionary of English v.0.48</name> </invoker.Dictionary> <invoker.Dictionary> <id>wn</id> <name>WordNet (r) 2.0</name> </invoker.Dictionary> <invoker.Dictionary> <id>moby-thes</id> <name>Moby Thesaurus II by Grady Ward, 1.0</name> </invoker.Dictionary> in this: invoker.ArrayOfDictionary: dictionary: invoker.Dictionary: id:gcide name:The Collaborative International Dictionary of English v.0.48 invoker.Dictionary: id:wn name:WordNet (r) 2.0 invoker.Dictionary: id:moby-thes name:Moby Thesaurus II by Grady Ward, 1.0 I was thinking to do this with XSLT transformation. Some guidelines how to start with xslt? Or maybe you have another idea for this?

• How to make Processes Run Parallel in Erlang?

  - by Ankit S

  Hello, startTrains() -> TotalDist = 100, Trains = [trainA,trainB ], PID = spawn(fun() -> train(1,length(Trains)) end), [ PID ! {self(),TrainData,TotalDist} || TrainData <- Trains], receive {_From, Mesg} -> error_logger:info_msg("~n Mesg ~p ~n",[Mesg]) after 10500 -> refresh end. so, I created Two Processes named trainA, trainB. I want to increment these process by 5 till it gets 100. I made different processes to make each of the train (process) increments its position parallely. But I was surprised to get the output sequentially i.e process trainA ends then process trainB starts. But I want to increment themselves at simultaneously. I want to run processes like this trainA 10 trainB 0 trainA 15 trainB 5 .... trainA 100 trainB 100 but I m getting trainA 0 .... trainA 90 trainA 95 trainA 100 trainA ends trainB 0 trainB 5 trainB 10 ..... trainB 100 How to make the processes run parallel/simultaneously? Hope you get my Q's. Please help me.

• How can I select values from different rows depending on the most recent entry date, all for the sam

  - by user321185

  Basically I have a table which is used to hold employee work wear details. It is formed of the columns: EmployeeID, CostCentre, AssociateLevel, IssueDate, TrouserSize, TrouserLength, TopSize & ShoeSize. An employee can be assigned a pair of trousers, a top and shoes at the same time or only one or two pieces of clothing. As we all know peoples sizes and employee levels can change which is why I need help really. Different types of employees (associatelevels) require different colours of clothing but you can ignore this part. Everytime an employee receives an item of clothing a new row will be inserted into the table with an input date. I need to be able to select the most recent clothes size for each item of clothing for each employee. It is not necessary for all the columns to hold values because an employee could receive trousers or poloshirts at different times in the year. So for example if employee '54664LSS' was given a pair of 'XL' trousers and a 'L' top on 24/03/11 but then received a 'M' top on 26/05/10. The input of these items would be help on two different rows obviously. So if I wanted to select the most recent clothing for each clothes category. Then the values of the 'M' sized top and the 'L' sized trousers would need to be returned. Any help would be greatly appreciated as I'm pretty stuck :(. Thanks.

• Zend file upload error

  - by jgnasser

  I am attempting to upload a file using Zend Framework 1.8 and I get some errors. Here is the code snippet: The form element: $element = new Zend_Form_Element_File('doc'); $element->setLabel('Upload an image:') ->setDestination('/path/to/my/upload/folder'); $element->addValidator('Count', false, 1); $element->addValidator('Size', false, 102400); $element->addValidator('Extension', false, 'jpg,png,gif,doc,docx,xls,xlsx,txt'); $this->addElement($element); The code for handling the upload: $adapter = new Zend_File_Transfer_Adapter_Http(); if (!$adapter->receive()) { $messages = $adapter->getMessages(); echo implode("\n", $messages); } This works fine and the file is uploaded but I get the error "The file 'doc' was illegal uploaded, possible attack". I managed to get past this problem by not creating a new Zend_File_Transfer_Adapter_Http() but instead using: $adapter = $form->doc->getTransferAdapter(); With this modification, the first error disappears but now I have an error saying I have provided 2 files instead of one (probably its reading the temp) and when I adjust the validator to accept two files I then get the arror saying "The file 'doc' was not found" and the upload now fails completely. Please help
