  • Redirect Log output to sdcard on customer's phone

    - by Tom
    My customers are having a problem with my app, and I have been unable to reproduce the problem on my development phone. How to debug this problem? The android Log class is great, but my customers do not know how to use 'adb' or the USB debug cable. Is there some way to redirect Log output to a file on the phone's SD card? Then the customer could easily email the log file to me. Even if this redirection requires programming on my part, I could at least distribute a 'debug' version of the app. Thanks, Tom

  • Using Excel To Read Access Without MS Access On Computer

    - by Tom Clark
    I have written code that joins two table in access, using criteria supplied from drop down lists in excel and then returns the data to a specific location on the spreadsheet (titles already on the sheet). This works fine on my box and others with MS Access on the machine, but the purpose of writing this was to give people (associates) that dont have the MS Access on their machines (which is most of them) to be able to do simple queries to the database. When we try to run this on a machine without MS Access, we are getting the error message "Compile Error: Cant find project or library." Since this works fine on any machine so far that has Access, but not the others I am wondering if this is not possible without the actual Access software. Any help or insight would be appreciated.

  • jQuery Validation Plugin + equalTo Not Working

    - by Tom Winchester
    Hey guys, Here is what I am currently using to attempt to validate a form. When I press submit with no values entered into the form, I get the error messages for each of the inputs as expected. However, no matter what I put in newpassword2 or newemail2 they never 'pass' validation. I've tried everything from copy and paste to making them one letter each to no success. Perhaps I am not using the equalTo attribute correctly... I've also verified that all the names of the selectors agree with the input id's on the form. Also, all of the inputs are contained within the form, so there aren't any outside of the form tags (I read that was an issue with someone else). $(document).ready(function() { $("#account_data").validate({ rules: { newpassword1: { required: true }, newpassword2: { equalTo: "#newpassword1" }, newemail1: { required: true, email: true }, newemail2: { equalTo: "#newemail1" } } }); }); Any help would be extremely appreciated! THANK YOU!!! -Tom-

  • Query for model by key

    - by Jason Hall
    What I'm trying to do is query the datastore for a model where the key is not the key of an object I already have. Here's some code: class User(db.Model): partner = db.SelfReferenceProperty() def text_message(self, msg): user = User.get_or_insert(msg.sender) if not user.partner: # user doesn't have a partner, find them one # BUG: this line returns 'user' himself... :( other = db.Query(User).filter('partner =', None).get() if other: # connect users else: # no one to connect to! The idea is to find another User who doesn't have a partner, that isn't the User we already know. I've tried filter('key !=, user.key()), filter('__key__ !=, user.key()) and a couple others, and nothing returns another User who doesn't have a partner. filter('foo !=, user.key()) also returns nothing, for the record.

  • Staging server .htaccess for images, css and js

    - by Gavin Hall
    As we build and demo sites on our staging server with individual root folders for each such as /CLIENTNAME, we need to keep all the css, js and internal links for these sites referencing the server root. The following works for one folder each, but not sure how to adapt to work for all folders. Currently AddHandler php5-script .php RewriteEngine On RewriteRule ^(images|css|js)\/(.*) /ONEFOLDER/$1/$2 Would like AddHandler php5-script .php RewriteEngine On RewriteRule ^(images|css|js)\/(.*) /EVERYFOLDER/$1/$2 Many thanks in advance.

  • Is it possible to access raw iphone audio output?

    - by Peter Hall
    Is it possible access raw PCM data from the iphone audio output? I know I can embed an MP3 and use AudioUnit. But if the user is playing music in the background from their itunes library, is it possible to access that audio data? This is for an app that shows visual effects, which react to the music. From what I can tell, it isn't possible, but that's just from lack of finding any information at all, rather than actual confirmation that it can't be done. If it isn't possible to access the audio stream from the ipod, is it possible to access raw audio output from the Media Player inside an app, or is pretty much not permitted to access raw audio data from the itunes library at all? EDIT: I found this question: iOS - Access output audio from background program, which say I can't access the audio from a background app. But is it possible to get the audio data from the itunes library if I play it inside the app?

  • WindowsPhone App data connection FAILS in MarketPlace published App but WORKS in Visual Studio development (same XAP)

    - by Tom
    Tearing my hair out(!) My last App update has been accepted and released by MarketPlace but the remote server data connection does NOT work/connect from the downloaded App (from MarketPlace). However, the same App (the accepted XAP) when I'm running it from Visual Studio, using the same remote server address works just fine. WHY!... Has anyone else ever run into anything like this? Here's the remote path: http://www.streamcommunication.com/ZenAwaken/DownloadableCollections.xml I can load that to a browser and retrieve the XML When I'm in Visual Studio I can connect via that path and retrieve the file and consume the data BUT!! The exact same XAP which has been accepted and distributed by Windows Phone marketplace FAILS. Is it possible that MarketPlace does something (encryption?) to the XAP that would corrupt the path string? Any thoughts or experiences would be very helpful! Tom

  • Linux: Managing users, groups and applications

    - by RN
    I am fairly new to linux admin so this may sound quite a noob question. I have a VPS account with a root access I need to install Tomcat, Java on it and later other open source applications as well. Installation for all of these is as simple as unzipping the .gz in a folder. My questions are A) Where should I keep all these programs? In Windows, I typically have a folder called programs under c:\ where I unzip all applications. I plan to have something similar here as well. Currently, I have all these under apps folder under/root- which I am guessing is a bad idea B) To what group should Tom belong to ? I would need a user - say Tom who can simply execute these programs. Do I need to create a new group? or just add Tom to some existing group ? C) Finally- Am I doing something really stupid by installing all these application by simply unzipping them? I mean an alternate way would be to use Yup or RPM or something like that to install these applications. Given my familiarity and (tight budget) that seems too much to me. I feel uncomfortable running commands which i don't understand too well

  • httpd.conf configuration - for internal/external access

    - by tom smith
    hey. after a lot of trail/error/research, i've decided to post here in the hopes that i can get clarification on what i've screwed up... i've got a situation where i have multiple servers behind a router/firewall. i want to be able to access the sites i have from an internal and external url/address, and get the same site. i have to use portforwarding on the router, so i need to be able to use proxyreverse to redirect the user to the approriate server, running the apache/web app... my setup the external urls joomla.gotdns.com forge.gotdns.com both of these point to my router's external ip address (67.168.2.2) (not really) the router forwards port 80 to my server lserver6 192.168.1.56 lserver6 - 192.168.1.56 lserver9 - 192.168.1.59 lserver6 - joomla app lserver9 - forge app i want to be able to have the httpd process (httpd.conf) configured on lserver6 to be able to allow external users accessing the system (foo.gotdns.com) be able to access the joomla app on lserver6 and the same for the forge app running on lserver9 at the same time, i would also like to be able to access the apps from the internal servers, so i'd need to be able to somehow configure the vhost setup/proxyreverse setup to handle the internal access... i've tried setting up multiple vhosts with no luck.. i've looked at the different examples online.. so there must be something subtle that i'm missing... the section of my httpd.conf file that deals with the vhost is below... if there's something else that's needed, let me know and i can post it as well.. thanks -tom ##joomla - file /etc/httpd/conf.d/joomla.conf Alias /joomla /var/www/html/joomla <Directory /var/www/html/joomla> </Directory> # Use name-based virtual hosting. #NameVirtualHost *:80 # NOTE: NameVirtualHost cannot be used without a port specifier # (e.g. :80) if mod_ssl is being used, due to the nature of the # SSL protocol. # VirtualHost example: # Almost any Apache directive may go into a VirtualHost container. # The first VirtualHost section is used for requests without a known # server name. #<VirtualHost *:80> # ServerAdmin [email protected] # DocumentRoot /www/docs/dummy-host.example.com # ServerName dummy-host.example.com # ErrorLog logs/dummy-host.example.com-error_log # CustomLog logs/dummy-host.example.com-access_log common #</VirtualHost> NameVirtualHost 192.168.1.56:80 <VirtualHost 192.168.1.56:80> #ServerAdmin [email protected] #DocumentRoot /var/www/html #ServerName lserver6.tmesa.com #ServerName fforge.tmesa.com ServerName fforge.gotdns.com:80 #ErrorLog logs/dummy-host.example.com-error_log #CustomLog logs/dummy-host.example.com-access_log common #ProxyRequests Off ProxyPass / http://192.168.1.81:80/ ProxyPassReverse / http://192.168.1.81:80/ </VirtualHost> <VirtualHost 192.168.1.56:80> #ServerAdmin [email protected] DocumentRoot /var/www/html/joomla #ServerName lserver6.tmesa.com #ServerName fforge.tmesa.com ServerName 192.168.1.56:80 #ErrorLog logs/dummy-host.example.com-error_log #CustomLog logs/dummy-host.example.com-access_log common #ProxyRequests Off </VirtualHost>

  • Managing Dependency Hell with WiX and C#

    - by Tom the Junglist
    We are on the eve of product launch, and at the last minute I am being bombarded with crash reports that appear to be related to our installer, which is a WiX3 project with separate outputs for x86 and x64 builds. These have been an ongoing problem that I always thought were fixed, only to find out that they were still lurking. The product itself is a collection of binaries that communicate with each other via .Net remoting, including a Windows Service and a small COM component that is loaded as an addon in another app. The service runs as SYSTEM, the COM piece runs in a low-rights context, while the other pieces run in normal user contexts. Other pieces include an third-party COM object library DLL and a shared DLL with the .net Remoting interfaces. I've observed flat-out weird behavior with MSI, particularly on version upgrades. Between MS' anal strong-name implementation (specifically, the exact version check before loading a given assembly), a documented WiX/MSI bug that sees critical files erased on upgrades (essentially, if a file in the upgrade MSI has the same version number as the existing install, that file is deleted), and having to work around Wow64 virtualization (x86 MSI can only write to registry/HD locations via Wow64, yet x64 MSIs cannot run on x86 computers...), I am about ready to trash the whole thing and port it over to a different install system. What I am looking for on tips + tricks, techniques, or suggestions on how to properly do things so that I am not fighting with Windows Installer's twisted sense of logic. I am tired of fighting with WiX/MSI/Windows Installer. All it needs to do is place files and registry keys where I tell it to, upgrade them when appropriate, and don't delete anything until the user uninstalls. Instead, dependencies are deleted willy-nilly, bringing up a whole bunch of uncatchable exceptions (can't wrap a try{} block around function declarations) and GPF'ing the whole app. I am particularly interested in 'best practices' and examples regarding shared and dependency DLLs, and any tips on making sure if a file needs to go to GAC, that it actually goes to the GAC and stays there until it is appropriate to remove it. Thanks! Tom

  • MSBuild: building website using AspNetCompiler - adding references?

    - by Tom Morgan
    Hi, I'm attempting to build a ASP.NET website using MSBuild - specifically the AspNetCompiler tag. I know that, for my project, I need to add some references. Within Visual Studio I have several references, one is a project reference and the others are some DLLS (AjaxControlToolkit etc). I'm happy not referencing the project and referencing the DLL instead - however I just can't work out how to add a reference. I've looked up and down and this is what I've found so far: <Target Name = "PrecompileWeb"> <AspNetCompiler VirtualPath = "DeployTemp" PhysicalPath = "D:\AutoBuild\CruiseControl\Projects\Websites\MyCompany\2.0.0\WorkingDirectory\VSS" TargetPath = "D:\AutoBuild\CruiseControl\Projects\Websites\MyCompany\2.0.0\PreCompiled" Force = "true" Debug = "true" Updateable = "true"/> </Target> Also - I've picked up this bit of code from around the web somewhere, which I thought might help: <ItemGroup> <Reference Include="My.Web.DataEngine, Culture=neutral, processorArchitecture=MSIL"> <SpecificVersion>False</SpecificVersion> <HintPath>D:\AutoBuild\CruiseControl\Projects\Components\My.Web.DataEngine\bin\Debug\My.Web.DataEngine.dll</HintPath> </Reference> </ItemGroup> What I want to do is add a attribute to the AspNetCompiler tag, something like: References="@(Reference)" but MSBuild isn't very happy about this. I've been a bit stuck in not being able to find decent references on doing this anywhere: so I'd really apprechiate some pointers or reference material etc. (or just the answer!) Thanks for you help. -tom

  • WiX: Prevent 32-bit installer from running on 64-bit Windows

    - by Tom the Junglist
    Hi everyone, Due to user confusion, our app requires separate installers for 32-bit and 64-bit versions of Windows. While the 32-bit installer runs fine on win64, it has the potential to create support headaches and we would like to prevent this from happening. I want to prevent the 32-bit MSI installer from running on 64-bit Windows machines. To that end I have the following condition: <Condition Message="You are attempting to run the 32-bit installer on a 64-bit version of Windows."> <![CDATA[Msix64 AND (NOT Win64)]]> </Condition> With the Win64 defined like this: <?if $(var.Platform) = "x64"?> <?define PlatformString = "64-bit"?> <?define Win64 ?> <?else?> <?define PlatformString = "32-bit"?> <?endif?> Thing is, I can't get this check to work right. Either it fires all the time, or none of the time. The goal is to check presence of the run-time msix64 variable against the compile-time Win64 variable and throw an error if these don't line up, but the logic is not working how I intend it to. Has anyone come up with a better solution? Thanks! Tom

  • iPhone Safari does not auto scale back down on portrait->landscape->portrait

    - by Tom
    Hi, I have a very simple HTML page with this META tag for the iPhone: <meta name="viewport" content="height=device-height,width=device-width,initial-scale=1.0,user-scalable=no" /> When the page loads in portrait mode it looks fine and the width fits the screen. When I rotate the iPhone to landscape mode the web page is auto resized to fit the landscape width. Good, this is what I want. But when I rotate back to landscape, the page is not resized back to fit the portrait width like it was before. It remains in the landscape width. I want the iPhone to set it back to the right width automatically, just like it did for the landscape mode. I don't think this should involve orientation listeners because it is all done automatically and I don't have any special styling for the different modes. Why doesn't the iPhone resize the web page back in portrait mode? How do I fix this? Thanks! Tom.

  • Fade out when user leaves page — jquery

    - by Tom Julian Hume
    I have some simple page transitions that fade in, once the user has landed. However, I'm also trying to make the same page fade out, when the user leaves. I have found a few solutions, but they appeared to use delay(). Are there any that don't? Thanks for any help, (I'm new to this, mind!) Tom :) I am currently using this code: $(document).ready( function(){ $( 'body' ).fadeIn(2000); $('#stop').click(function (e) { e.preventDefault(); }); $('#clients').click(function() { $("#projectinfo").slideUp('slow'); $("#us").fadeOut('slow'); $("ul").fadeToggle('slow'); }); $('#information').click(function() { $("#projectinfo").slideUp('slow'); $("ul").fadeOut('slow'); $("#us").fadeToggle('slow'); }); $('#question').click(function() { $("#projectinfo").slideToggle('slow'); }); $('#question').hover(function() { $("#projectinfo").slideToggle('slow'); }); $("a").click(function(event){ event.preventDefault(); linkLocation = this.href; $("body").fadeOut(1000, redirectPage); }); function redirectPage() { });

  • Evaluation of environment variables in command run by Java's Runtime.exec()

    - by Tom Duckering
    Hi, I have a scenarios where I have a Java "agent" that runs on a couple of platforms (specifically Windows, Solaris & AIX). I'd like to factor out the differences in filesystem structure by using environment variables in the command line I execute. As far as I can tell there is no way to get the Runtime.exec() method to resolve/evaluate any environment variables referenced in the command String (or array of Strings). I know that if push comes to shove I can write some code to pre-process the command String(s) and resolve enviroment variables by hand (using getEnv() etc). However I'm wondering if there is a smarter way to do this since I'm sure I'm not the only person wanting to do this and I'm sure there are pitfalls in "knocking up" my own implementation. Your guidance and suggestions are most welcome. edit: I would like to refer to environment variables in the command string using some consistent notation such as $VAR and/or %VAR%. Not fussed which. edit: To be clear I'd like to be able to execute a command such as: perl $SCRIPT_ROOT/somePerlScript.pl args on Windows and Unix hosts using Runtime.exec(). I specify the command in config file that describes a list of jobs to run and it has to be able to work cross platform, hence my thought that an environment variable would be useful to factor out the filesystem differences (/home/username/scripts vs C:\foo\scripts). Hope that helps clarify it. Thanks. Tom

  • Java NIO (Netty): How does Encryption or GZIPping work in theory (with filters)

    - by Tom
    Hello Experts, i would be very thankfull if you can explain to me, how in theory the "Interceptor/Filter" Pattern in ByteStreams (over Sockets/Channels) work (in Asynchronous IO with netty) in regard to encryption or compression of data. Given I have a Filter that does GZIPPING. How is this internally implemented? Does the Filter "collect" so many bytes form the channel, that this is a usefull number of bytes that can then be en/decoded? What is in general the minimal "blocksize(data to encode/decode in a chunk)" of socket based gzipping? Does this "blocksize" have to be negotiated in advance between server and client? What happens if the client does not send enough data to "fill" the blocksize (due to a network conquestion) but does not close the connection. Does this mean the other side will simply wait until it gets enough bytes to decode or until a timeout occoures...How is the Filter pattern the applied? The compression filter will de/compress the blocksize of bytes and then store them again in the same buffer would (in the case of netty) i normally be using the ChannelHanlderContext to pass the de/encoded data to the next filter?... Any explanations/links/tutorials (for beginners;-) will be very much appreciated to help me understand how for example encryption/compressing are implemented in socket based communication with filters/interceptor pattern. thank you very much tom

  • Majordomo/Mailman - Yahoo/Google Groups

    - by tom smith
    Hi. Not an app question, but thought that I might ask here anyway! The responses might help someone. I've got an app where we're going to be dealing with 5000-10000 people in a group/pool. Periodically, different subsets of people will break off in their own group. I'm looking for thoughts on how to manage/approach this situation. (For now, all of this is being managed on a few servers in the garage, with dynamic IP) I've looked into the Yahoo/google groups, and they seem to be reasonable. The primary issue that I see with this approach, is that I don't have a good way of quickly/easily alowing a subset of the group to form their own group for a given project. This kind of function is critical. The upside to this though, I wouldn't have to really set anything up. And the hosted groups could send emails to the user all day along, without running into cap/bandwidth limits The other approach is a managed list, like mailman/majordomo. This approach appears to be more flexible, and looks like ti could be modified to handle the quick creation of lists, allowing users to quickly be assigned to different lists on the fly.. The downside, I'd have to run my own Mailman/Majordomo instance, as well as the associated mail server. Or I could look at possibly using one of the hosted service.. But this is for a project on the cheap, so we're really trying to keep costs down. Thoughts/Comments/Pointers would be greatly appreciated. Thanks in advance -tom

  • Workflow engine BPMN, Drools, etc or ESB?

    - by Tom
    We currently have an application that is based on an in-house developed workflow engine with YAML based DSL. We are looking to move parts of it to Java. I have discovered a number of java solutions like Intalio, JBPM, Drools Expert, Drools Flow etc. They appear to be aimed at businesses where the business analyst creates the workflows using a graphical editor and submits them to the workflow engine. They seem geared towards ease of use for non-technical people rather than for developers with a focus on human interaction. The workflows tend to look like. Discover-a-file -\ -> join -> process-file -> move-file -> register-file Discover-some-metadata -/ If any step fails we need to retry it X times. We also need to be able to stop the system and be able to restart it and have it continue from where it was (durable). Some of our workflows can be defined by a set of goals we need to achieve so Jess's backwards rule chaining sounds interesting but it is not open source. It might be that what we are after is a Finite State Machine engine or just an Enterprise Service Bus and do everything as JMS queues. Is there a good open source workflow engine that is both standards-based but also geared towards developers. We don't particular want to use a graphical workflow designer or write reams of XML and it should ideally be in Java or language agnostic (makes REST/Soap calls to external services). Thanks, Tom
