• SOS: AudioFormat when writing to file in FreeTTS

  - by user330793

  Very annoying problem. I have developed a freeTTS application of the freetts class that write captured audio to file however I am having some very annoying problems. When setting the audio player to singlefileaudio player I try to also set the audioformat with my own default values for sampleRate, sampleSizeInBits, channels, signed and bigEndian. Now I access AudioPlayer.get methods to show these values in runtime just to ensure they are set to what I set them and they match those values. However when file writing completes and I check the properties of the resulting wave file, they are set to the audioPlayer default settings. Normally this will be fine except I have to read the files into another application which has fixed audio property settings so I always get a resulting output that sounds like am fast forwarding the sound and listening to it at the same time. Obviously because of the different sampling rates. I need help please. Thanx, Henry

• iPhone - cannot run code on device

  - by lostInTransit

  Hi I have some source code which I had developed and later gave to another team. They signed it with their certificate and provisioning profile. Now I have the code back and have set the appropriate values in the project properties for code signing identity (with my cert and profile). But when I run the application on a device, I get an error showing the other team's certificate and prompting that the provisioning profile does not exist. I don't know where it is being referenced. Can someone please help. Thanks.

• How to explain to a client that you've gone over-budget and you'll need more money/time to deliver w

  - by General Tapioca

  My situation is that I have agreed on a per-project proposal with the client. The proposal is vague, but still names functionality in a way that can be argued as to whether it's included or not, while leaving some room for interpretation. I originally pressed as much as I could to get a per-month contract, arguing that the project is mostly non-predictable, but the client refused. Being a small company, I had to fold and signed a contract on an estimate based on my group's estimations. At this point we have reached completion on about 85% of the features (we think) but we ran out of budget. We have been working for almost two years with this client in previous contracts, and we have delivered a good product that they are happy with, so we have a good standing relationship. More info: -There has been a bit of scope-creep, but I don't think enough for me to hide behind that argument -We've been delivering partial releases about monthly. -We don't have systematic user-testing in place.

• How can I update the version of an APK which I did not create myself

  - by sylvanaar

  I am new to Android development. I am using a x-platform development tool which builds and signs the APK for me. This tool has a bug and it does not generate APK's with the version number I specify, all APK's generated are version 1.0. I would like to unpack the APK, edit the version number, and then resign and repackage it. It was signed using my keystore originally, so I have the keys needed to sign it again. How can this be done?

• j2me PushRegistry.RegisterAlarm and code signing

  - by Mihir

  I am developing an app on Nokia C2-00 in which I am using push registry for auto start of app on some fixed time ex. PushRegistry.registerAlarm("ClassName", alarm.getTime()); this is working perfect and it starts app on that time. But this is asking me for permissions two times. 1) when I am registering alarm using PushRegistry.registerAlarm("ClassName", alarm.getTime()); 2) when app start on that defined time. in this and this link I found that if my application is signed then it will not ask for permission when app autostart. but I am not sure about the time when my code will register alarm. Will it ask for permission or not?

• Is there an easy way to sign a C++ CLI assembly in VS 2010?

  - by jyoung

  Right now I am setting the Linker/Advanced/KeyFile option. I am getting the "mt.exe : general warning 810100b3: is a strong-name signed assembly and embedding a manifest invalidates the signature. You will need to re-sign this file to make it a valid assembly.". Reading from the web, it sounds like I have to set the delay signing option, download the SDK, and run sn.exe as a post build event. Surely there must be an easier way to do this common operation in VS2010?

• How can I use Amazon's API in PHP to search for books?

  - by TerranRich

  I'm working on a Facebook app for book sharing, reviewing, and recommendations. I've scoured the web, searched Google using every search phrase I could think of, but I could not find any tutorials on how to access the Amazon.com API for book information. I signed up for an AWS account, but even the tutorials on their website didn't help me one bit. They're all geared toward using cloud computing for file storage and processing, but that's not what I want. I just want to access their API to search info on books. Kind of like how http://openlibrary.org/ does it, where it's a simple URL call to get information on a book (but their databases aren't nearly as populated as Amazon's). Why is it so damned hard to find the information I need on Amazon's AWS site? If anybody could help, I would greatly appreciate it.

• Canonicalizing XML in Ruby

  - by whazzmaster

  I'm working on a SAML gateway using Ruby/Rails and I'm attempting to write some code that validates the xml digital signature of the incoming SAML response against the x509 cert of the originating service. My problem: the signature depends on a canonicalized version of the XML that is hashed and then signed and I'm having trouble finding a ruby lib/gem that will canonicalize XML per the spec. I found a super old gem on rubyforge that is a mess but I'd be more interested if something like nokogiri supported this kind of functionality (from the nokogiri docs, it doesn't). I've googled extensively but thought I'd ask around here to see if anyone has any good insights before I go and try to write my own version or rework the existing c14n-r library.

• How to get the Facebook iFrame Tab url (including parameters) from within the app?

  - by martincarlin87

  I think there are a few similar questions that seem to suggest using app_data in the signed request (http://developers.facebook.com/docs/authentication/signed_request/) but I'm not sure if it will be possible to do what I am trying to achieve with it as I've never used it before. If I have my Facebook 'Tab' Url as follows: http://www.facebook.com/pages/PAGE_TITLE/PAGE_ID?sk=app_APP_ID What I want to do is add an extra parameter on the end as follows: &WT.mc_id=email-uk-8014 The reason for this is for tracking purposes and links will be sent out of the form http://www.facebook.com/pages/PAGE_TITLE/PAGE_ID?sk=app_APP_ID&WT.mc_id=email-uk-8014 and the extra parameter will allow us to track the campaign id. As you can see I have no way of knowing the value of the parameter beforehand as it depends on the link clicked by the user so is it possible to somehow get the value of the WT.mc_id parameter inside my iframe app?

• Favoriting system on Appengine

  - by Mateusz Cieslak

  Hi, I have the following model structure class Authors(db.Model) : nickname = db.StringProperty(required=True) fullname = db.StringProperty(required=True) class Articles(db.Model) : title = db.StringProperty(required=True) body = db.StringProperty(required=True) author = db.ReferenceProperty(Authors, required=True) class Favorites(db.Model) : who = db.ReferenceProperty(Authors, required=True) what = db.ReferenceProperty(Articles, required=True) I'd like to display 10 last articles according to this pattern: article.title, article.body, article.author(nickname), info if this article has been already favorited by the signed in user. I have added a function which I use to get the authors of these articles using only one query (it is described here) But I don't know what to do with the favorites (I'd like to know which of the displayed articles have been favorited by me using less than 10 queries (I want to display 10 articles)). Is it possible?

• Twitter @Anywhere oauth_bridge_code

  - by AngelCabo

  I'm having trouble with Twitter's implementation of an oauth_bridge_code for the @anywhere api. I've seen a few walkthrough's on how to use this functionality but I can't seem to get the request to work for me. I'm using Ruby on Rails with the oauth gem. My code is as follows: def callback consumer = OAuth::Consumer.new(APP_CONFIG['twitter_key'], APP_CONFIG['twitter_secret'], :site => "http://api.twitter.com", :request_token_path => "/oauth/request_token", :authorize_path => "/oauth/authorize", :access_token_path => "/oauth/access_token", :http_method => :post) request = OAuth::AccessToken.new consumer json = request.post("https://api.twitter.com/oauth/access_token?oauth_bridge_code=#{params[:oauth_bridge_code]}") end I keep getting 401 unauthorized responses from the signed post request even though this is supposed to be working according to this walkthrough: http://blog.abrah.am/2010/09/using-twitter-anywhere-bridge-codes.html and a presentation from Matt Harris on slideshare. Any ideas on what I'm doing wrong (besides possibly trying to hit functionality that may not be in place)? Greatly appreciated!

• Using Web Flow 2 in JSF application

  - by Tesnep

  Hi, I created a JSF cart application which runs just fine. I am using 'redirect' to fix the problem with refresh. The problem is when there is multiple page flow logic like if you haven't signed up you need to sign up or create an account, and once you do that you need to be redirected back to where you were when you were asked to sign up in the first place. So my goal is to use Web Flow 2 in order to make navigation rules easier to code. I have been working on them separately but I don't know how to merge so that Web Flow can handle navigation instead. Any help is very much appreciated. Thanks.

• Omniauth + Pow Issue

  - by neon

  I am having a strange issue with Pow and Omniauth. Omniauth (Facebook Login) works fine when using localhost:3000, but when using Pow (appname.dev) things get fishy. Users are taken through the redirect and properly created if they don't exist in the database, as they should be. After this, however, they are redirected to the root_path and not signed in. Their record is saved in the database as expected, but sign in does not occur. Again, this is only happening on Pow (and lvh.me), and not on localhost. Any ideas? I am using the Devise/Omniauth approach for sign-in, and the controller code looks like this: def facebook @user = User.find_for_facebook_oauth(request.env["omniauth.auth"], current_user) if @user.persisted? flash[:notice] = I18n.t "devise.omniauth_callbacks.success", :kind => "Facebook" sign_in_and_redirect @user, :event => :authentication else session["devise.facebook_data"] = request.env["omniauth.auth"] redirect_to new_user_registration_url end end Again, the user is persisted but there is no flash notice or sign_in that occurs when using POW.

• Android Jar libraries

  - by Jeremy Edwards

  How do you setup a project that can result in a jar library file that can be used for android? I want to create a custom library across all projects. Few other questions: Does it need to be compiled against a specific version of android sdk? When an android package is compiled against a jar library does the classes necessary to work with the code get compiled with main code into the apk or does the entire jar get included? Any notable optimizations or pitfalls I need to know about with using a jar instead of integrating the code directly? Does the jar have to be signed like the apk needs to?

• check external website registration

  - by Arsenal

  Hi, I'm trying to create a PHP based game where you have to do all sorts of simple but un-obvious tasks in order to progress to the next level (eg. refresh browser, press keyboard combination, ...) Kinda like the game "this is the only level" (if anyone has ever heard of it) Now I was thinking: Would it be possible to create a level where they'd have to sign up at a different page in order to progress to the next level? So say for example they need to sign up to goal.com and if they're signed up they proceed to the next level. The page would need to constantly check if the signup process on the other site is completed. Is this even possbible? And if so, any thoughts on how? Thanks!

• Help with calling a secure (SSL) webservice in Android.

  - by mmattax

  I'm new to Android and am struggling to make a call to an SSL web service for an Android Application. My code is as follows: Log.v("fs", "Making HTTP call..."); HttpClient http = new DefaultHttpClient(); HttpGet request = new HttpGet("https://example.com/api"); try { String response = http.execute(request, new BasicResponseHandler()); Log.v("fs", response); } catch (Exception e) { Log.v("fs", e.toString()); } The Output is: Making HTTP call... javax.net.SSLPeerUnverifiedException: No peer certificate Any suggestions to make this work would be great. EDIT I should note that this is a valid cert. It is not self-signed.

• Faster way to convert from 24 bit wav pcm format to float?

  - by LMO

  I need to read data in from a wav file in 24 bit pcm format, and convert to float. I'm using Python 2.7.2. The wave package reads the data in as a string, so what I've tried is: # read in entire wav file wdata = f.readframes(nFrames) # unpack into signed integers and convert to float data = array.array('f') for i in range(0,nFrames*3,3): data.append(float(struct.unpack('<i', '\x00'+ wdata[i:i+3])[0])) # normalize sample values data = data / 0x800000 This is quite a bit faster than my earlier approaches, but still quite slow. Can anyone suggest a more efficient method?

• Ajax: Load XML from different domain?

  - by John Isaacks

  I have signed up(paid) for Google site search. They have me a url of a sort of web service where I can send a query to it, it searches my site, and it returns XML of the search results. Well I am trying to load this XML via Ajax from a page on my site but I cannot. I can load from any of my pages on my domain so I am assuming it is because of the XML being on Google's domain. So there has got to be a way to load it though, I don't think they would have given me the URL if I couldn't do anything with it lol. Does anyone know how to do this? Thanks! UPDATE: this is what the page says on google that gave me the XML: How to get XML You can get XML results for your search engine by replacing query+terms with your search query in this URL: http://www.google.com/cse?cx=MY_UNIQUE_KEY&client=google-csbe&output=xml_no_dtd&q=query+terms Where MY_UNIQUE_KEY = my unique key.

• Browser application & local file system access

  - by Beyond HTML

  I want to enhance my browser-based web application with functionality that enables management of local files and folders. E.g. folder tree structures should be synchronized between local workstation and server via HTTP(S). I am aware of security-related limitations in browser-based applications. However, there are some techniques that "work around" these issues: Signed Java applets (full trust) .NET Windows Forms browser controls (no joke, that works. Just the configuration is horrible) ActiveX My question is: What do you use/suggest, both technology and implementation practice? Key requirement is that the installation process is as simple as possible. Thanks for your opinions!

• BizTalk external assembly namespace and static methods

  - by SteveC

  Is there some restriction in BizTalk 2006 R2 to accessing static methods in external assemblies when the assembly has a "." in the name ? I have the solution set-up with the BizTalk project "FooBar", and the external assembly project "FooBar.Helper" (strongly signed and GAC'ed) with a class "Demo" (public and serializable), which is referenced in the BizTalk project I can create a BizTalk variable of type "FooBar.Helper.Demo" and access an instance method fine, but an expression window the Intellisense shows the FooBar namespace, but if I dot it, I get the error "illegal dotted name" ??? However I can add another project, "ExtComp" with class "Test" and it's static methods are displayed in Intellisense !!! The only difference I can see is the first external assembly has the dot in it

• Reading Values Returned by SQLDataSource Before Binding to FormView

  - by peter.newhook

  I have a FormView that shows posts by users. I'd like to add Edit and Delete commands to the post to let the original author edit or delete their post. I'd like these commands to be available to only the author. The FormView is populated by a SqlDataSource that uses a stored procedure. I was thinking I would set the Edit and Delete hyperlink to Visible=False, then compare the currently signed in user guid to the guid of the post's author, and make the hyperlinks visible if the two guids are the same. I've tried using the Selected event of the SqlDataSource to capture the guid (which is returned by the stored procedure) however I can't find way to get the values returned by this datasource. How do I access the values returned by a SqlDataSource before they get databound?

• Why do C++ streams use char instead of unsigned char?

  - by Johannes Schaub - litb

  I've always wondered why the C++ Standard library has instantiated basic_[io]stream and all its variants using the char type instead of the unsigned char type. char means (depending on whether it is signed or not) you can have overflow and underflow for operations like get(), which will lead to implementation-defined value of the variables involved. Another example is when you want to output a byte, unformatted, to an ostream using its put function. Any ideas? Note: I'm still not really convinced. So if you know the definitive answer, you can still post it indeed.

• How to create digital signature that can not be used to reproduce the message twice

  - by freediver

  I am creating a client-server application and I'd like to send data from server to client securely. Using public/private key algorithms makes sense and in PHP we can use openssl_sign and openssl_verify functions to check that the data came by someone who has the private key. Now imagine that one of the actions sent by server to client is destructive in nature. If somebody uses an HTTP sniffer to catch this command (which will be signed properly) how can I further protect the communication to ensure that only commands coming from our server get processed by the client? I was thinking about using current UTC time as part of the encrypted data but client time might be off. Is there a simple solution to the problem?
