How to sign an APK with more than one certificate?

- by ddcruver

How do I sign an APK with more than one certificate, so that I can do this when I publish to the Android Market: Version 1.0 = Signed with Certificate A Version 2.0 = Signed with Certificate A & B Version 3.0 = Signed with Certificate B The Android Market does give me some hope but I am not sure what to make of it, when I upload with a different sign certificate it gives me this message: "The apk must be signed with at least one certificate in common with the previous version." Motive: I have published an app on the market using the Android Signing Tool as part of MotoDev Studio for android. The problem is that it handles the keys itself and there is no way (documented) to get them. I want to change it to use a keystore and certificate that I have more control of and can use even if I don't use MotoDev Studio anymore. Also it seems that MotoDev Studio will lock you out of new features such as shared libraries.

Is the situation with Java ME improving?

- by mike g

It seems to be the consensus that developing for Java ME is not as cross platform as you might expect, particularly compared to say java SE, but it is difficult to assess how the situation is evolving. Is the situation improving significantly? Are problematic implementations being patched? Are problematic implementations dying out as a proportion of mobile devices? Is the tool chain improving? Are there ways to identify at least some cross platform 'errors' without necessarily deploying to each and every device?

MonoTouch- 'curated' bindings?

- by Glinkot

I'm just converting a video player sample to MT and came to this part: self.view.layer.sublayerTransform = CATransform3DMakePerspective(1000); In Monotouch, I've started with: this.View.Layer.SublayerTransform(CATransform3D.... But no perspective option is available. There is a 'scale' and 'rotate' one - does this mean this functionality is unavailable in MT? Or that I need to start creating my own bindings even though this one has been processed by the binding creation tool Xamarin uses? If anyone could advise how I would apply that transform I'd appreciate it. Cheers

Displaying only the similarities between 20 or so files?

- by leeand00

Say I've got a directory full of html pages. Their headers and footers are basically the same, but I want to be able to see only the portions of all the pages that are the same. I'd like to call it an n-way merge, but that isn't what it is, it's looking for just the similarities between the header and the footers of all the files. (and my header I don't mean just the <head> tag, but rather the portions of the page that are alike). Note: There are like 20 html files. Is there a name for a tool that does this?

Advice on creating simple web service

- by London

Hi all, I want to build simple SOAP web service. So far I've only worked with existing SOAP/Rest services. And now I'd like to create my own, simple one for starters. For example create simple hello + string web service where I provide the string in request from SOAP ui or similar tool. I have Jboss server installed already, what is the "simplest" possible way to achieve this? I realize I need interface, interfaceImpl, and a wsdl file(generated possibly). Does anyone have some useful advice for me ? thank you

Is it possible to build this type of program in PHP?

- by Steven

I want to build a QA program that will crawl all the pages of a site (all files under a specified domain name), and it will return all external links on the site that doesn't open in a new window (does not have the target="_blank" attribute in the href). I can make a php or javascript to open external links in new windows or to report all problem links that don't open in new windows of a single page (the same page the script is in) but what I want is for the QA tool to go and search all pages of a website and report back to me what it finds. This "spidering" is what I have no idea how to do, and am not sure if it's even possible to do with a language like PHP. If it's possible how can I go about it?

C++ code generation for repeted task

- by sateesh

Hi, I have something like below which will get repeated many times based on the function that get called for e.g acceptfunction() { inserter["quantity"] = sdd.getfloat(quantity); inserter["prodtype"] = sdd.getstring(prodtype); : : so on } Like accept above there are 20 more functions(reject,cancel etc) which will do the similar thing.But the parameteres they insert can differ based on function called. How can I automate this kind of code.So that I dont need to write new function from scratch.Basically what I need is if i provide parametres like ("quantity",prodtype) through some text file or xml, it should generate the required function with the input parametres. Is this task can be handled through C++ tempalte Meta programming or someother code generation tool will help me to do this?

How to measure the time taken by C# NetworkStream.Read?

- by publicENEMY

I want to measure time taken for client to receive data over tcp using c#. Im using NetworkStream.Read to read 100 megabits of data that are sent using NetworkStream.Write. I set the buffer to the same size of data, so there no buffer underrun problem etc. Generally it looks like this. Stopwatch sw = new Stopwatch(); sw.Start(); stream.Read(bytes, 0, bytes.Length); sw.Stop(); The problem is, there is a possibility where the sender hasnt actually sent the data but the stopwatch is already running. how can i accurately measure the time taken to receive the data? i did try to use the time lapse of the remote pc stream.Write, but the time it took to write is extremely small. by the way, is the stopwatch is the most accurate tool for this task?

How to profiling my C++ application on linux

- by richard

HI, I would like to profile my c++ application on linux. I would like to find out how much time my application spent on CPU processing vs time spent on block by IO/being idle. I know there is a profile tool call valgrind on linux. But it breaks down time spent on each method, and it does not give me an overall picture of how much time spent on CPU processing vs idle? Or is there a way to do that with valgrind. Thank you.

Embed form in another website - pitfalls

- by Paddy

Scenario: We provide a hosted site that clients pay to use internally (a tool to support their business workflow). We have a requirement to provide a form that the clients can 'embed' in their outward facing site. This form will permit a member of the public to enter some details to register an interest - this data will be pushed to our remote system. Question: I'm currently planning on creating a simple HTML page that the client's web guys can include in a simple fashion on their site (either using an iframe or an object tag). If I do this, am I going to run into difficulties when the user tries to submit the embedded form (as it will be going to different domain to the one they are currently browsing)? I had a look at google adsense and I see that they just provide a link to a JS file that renders their ads - I'm not sure I see the advantage in this, but if anybody has any bright ideas... Whatever technique that gets used, I'll have to authenticate the request as coming from my client's site(s).

postback __EVENTTARGET ID in Page.Request.Form has $ not _ in ASP.NET

- by Industry86

I am using the ToolkitScriptManager from the Ajax tool kit and I am having a problem finding my button's ID. My ID's on my controls come back with $ symbols instead of _ symbols, like the following: Grid$ctl06$insertButton This obviously causes problems when attempting to find the control from the Page.Request.Form keys. I cannot seem to find the determining factor that would cause this. Now, I know this is the name and in my source I see that the ID is with the _, so why is the Page.Request.Form showing up with the $ symbol instead? Anybody encounter this before?

Offsite data storage for simple app, or a similar supported persistence mechanism?

- by jdk

Question Is there a usable facebook entry point to the Data Storage API that facebook lists on their app admin page for developers, or should I consider an alternate mechanism? What alternative mechanisms exist to simply persist my information offsite (away from my server app) without stuffing it into a cookie that's prone to expire? ... Background The facebook Data Store Admin tool is made available in a facebook App's Settings as seen here: (continue reading below) However when I visit the DataStoreAdmin link nothing works (i.e. clicking the buttons to define the data store types and objects does nothing - I have tried different browsers). The Wiki page for Data Store API hasn't been updated recently and the second last update says the beta Data Store was taken offline. It seems odd the link would be readily available and highly visible at the top of the App configuration area if indeed it's defunct. I was hoping some kind of key/value pair solution to remove the data calls from my own server.

Listing C/C++ functions (Code analysis in Unix)

- by Jond

Whether we're maintaining unfamiliar code or checking out the implementation details of an Apache module it can help if we can quickly traverse the code and build up an overview of what we're looking at. Grep serves most of my daily needs but there are some cases where it just wont do. Here's a common example of how it can help. To find the definition of a PHP function I'm interested in I can type this at the command line: grep -r "function myfunc" . This could be adapted very quickly to C or C++ if we know the return type, but things become more complicated if, say, I want to list every method that my class provides: grep "function " ./src/mine.class.php Since there's no single keyword that denotes a function or method in C++ and because it's generally more complex syntax, I think I'd need some kind of static code analysis tool, smart use of the C Preprocessor or blind faith the coder followed strict code guidelines (# of whitespace, position of curlies etc) to get these sorts of results. What would you recommend? p.s. be nice, this is my first post ;-) :p

Best memory settings for eclipse 4.2 (STS 3.1) on Windows 7 64 bit?

- by jorrebor

I apoligize in advance if this question is indeed too subjective as SO warns me. My workstation has 8 gb of ram and runs windows 7 64 bit. I use the Spring tool Suite (3.1) but as soon as i am starting to open and modify the spring config (.xml) files, STS becomes incredibly slow. I already tried switching off "build automatically" and to increase memory settings but no luck. How should i change my .ini ? this is what i have set now: -vm C:/Program Files/Java/jdk1.7.0_07/bin/javaw.exe -startup plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar --launcher.library plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20120522-1813 -product org.springsource.sts.ide --launcher.defaultAction openFile --launcher.XXMaxPermSize 4096M -vmargs -Dosgi.requiredJavaVersion=1.5 -Xms512m -Xmx2048m -XX:MaxPermSize=512m My collageu running the same project in IntelliJ, has no problems.

Flash: How to dispatch a click event at the top of a loaded .swf?

- by Myk

So I'm trying to build a tool that will allow me and other users to all open the same .swf, and then I as the Admin user am able to interact with mine while they all see my mouse movements and button clicks etc on theirs. I'm using BlazeDS to manage this and I'm getting data sent back and forth etc - no difficulties there. The issue I'm running into is this: In an "Admin" instance, I click a button. I capture that X and Y, then tell Blaze to tell my clients to dispatch a Click event at that X and Y. On my client side, I get that data and dispatch a Click event at that X and Y - but the click is actually caught at the stage level. The click on my client side takes place UNDER all of my buttons and other content - so the whole thing fails. Does this make sense? Is there a way to tell it to start the click event at the top?

How to deploy VS2008 express desktop project?

- by melaos

hi guys, i was wondering how could i deploy/make it into an installer for an app which is created using vs 2008 express. i know that the setup and deployment feature is only available via the full version of visual studio right? So are there any add ons or perhaps additional free/or non-free if it has to come to that which i can use to do this? or is the best tool for the job is the old visual studio installer from the vs 6.0 days? :) thanks Updates: After some googling, i found this link on using click once to deploy vs 2008 express with tutorials in them, i'll check it out, but of course more & better recommendation is always welcomed :)

Light effect with image magick

- by GuilhermeA

Hello, I'm using ImageMagick to resize an image to a smaller size gif. In this process I'm trying to give the image a light effect, not a side-light, just like a shiny look all over. Not a good comparison but for a better understanding think of an image seen in a old screen or an image seen in glossy monitor - I'm trying to enhance the image the closest to this point. An important point is that I can't make a image-to-image treatment, it must be something that I can use in all the images. I know ImageMagick is a powerful tool, and can certainly do something for my images! Many thanks!

deep zoom is not displayed

- by George2

I am using VSTS 2008 + C# + .Net 3.5 + Windows Vista Enterprise x86. I have used Silverlight Deep Zoom composer tool to export my composed images into Siverlight type. Everything is previewed fine after export successful message (I select browse from browser). But when I click the Test.html in the exported project to show Deep Zoom effects from browser, nothing is displayed. Here is my screen snapshot. Any ideas what is wrong? http://i41.tinypic.com/2dac561.jpg EDIT 1: to my surprise, there is no clientbin folder in my exported project. I have made two screen snapshots for, my project folder generated by Deep Zoom Composer under Exported Data folder; the content of GeneratedImages folder under my project folder. Please refers them to, http://i42.tinypic.com/346ncec.jpg http://i42.tinypic.com/15zqkn9.jpg Any ideas what is wrong? thanks in advance, George

Template apps for iPhone

- by rob

Is there a good place to get starter apps for iPhone, where you choose from any of a large set of permutations?...for instance with a nav bar and a flip screen and a 3 deep table view, with Core Data support etc. I guess what I was hoping for is some kind of wizard where you can check a few boxes and have a working app as a starting point....but more than just the 3 or 4 choices that come with xCode. If not a wizard, just a nice set of a couple dozen permutations. Also....is there any good sample apps out there that show the difference between identical apps, one which uses Interface Builder and one not? Aside from being handy for myself, I'd think these would be great as a teaching tool. I've googled a bit and come up with nothing.

Will an IO blocked process show 100% CPU utilization in 'top' output?

- by Alex Stoddard

I have an analysis that can be parallelized over a different number of processes. It is expected that things will be both IO and CPU intensive (very high throughput short-read DNA alignment if anyone is curious.) The system running this is a 48 core linux server. The question is how to determine the optimum number of processes such that total throughput is maximized. At some point the processes will presumably become IO bound such that adding more processes will be of no benefit and possibly detrimental. Can I tell from standard system monitoring tools when that point has been reached? Would the output of top (or maybe a different tool) enable me to distinguish between a IO bound and CPU bound process? I am suspicious that a process blocked on IO might still show 100% CPU utilization.

Tools for understanding large codebase

- by 0tar0gz

Hi! My whole life I have been programming in simple plain text editor. Lately, I was contemplating about joining an open source project which is fairly large and written in C. I downloaded the sources, started to look around, read this, forget that... Then I thought to myself: this can't be true. This is 21st century there must be some tool which would help me to understand the code, perhaps some kind of IDE or "code navigator". What flows from here to where, this typedef struct is just interface to that private type, this function is just #define from above, function called in this file is defined in that file, ... you get the idea. Dear Stack Overflow, is this 21st century? Is there something like this?
