• Access Java based keystore directly on Sun ONE Webserver 6.1

  - by George Bailey

  The keystore seems to reside in one of /opt/SUNWwbsvr/alias/https-sub.domain.ext-hostname-cert8.db /opt/SUNWwbsvr/alias/https-sub.domain.ext-hostname-key3.db What tool would I use to access this file? I have tried these commands which did not work. /opt/SUNWwbsvr/bin/https/jdk/bin/keytool -certreq -keyalg RSA -file /tmp/test.csr -keystore /opt/SUNWwbsvr/alias/https-sub.domain.ext-hostname-cert8.db /opt/SUNWwbsvr/bin/https/jdk/bin/keytool -certreq -keyalg RSA -file /tmp/test.csr -keystore /opt/SUNWwbsvr/alias/https-sub.domain.ext-hostname-key3.db /opt/SUNWwbsvr/bin/https/jdk/bin/keytool -list -storepass password -keystore /opt/SUNWwbsvr/alias/https-sub.domain.ext-hostname-cert8.db /opt/SUNWwbsvr/bin/https/jdk/bin/keytool -list -storepass password -keystore /opt/SUNWwbsvr/alias/https-sub.domain.ext-hostname-key3.db They all gave me the error message keytool error: java.io.IOException: Invalid keystore format

• Installing Java on a Virtual Private Server

  - by Martin Rowe

  I have recently managed to get my employer to pay for a vps. I teach and asked the vps provider to enable Perl, Python, Ruby, Tomcat and Java. They've done the first four (really quickly) but have got back to me asking which parts of Java I need. I think the Java Virtual Machine is a given but what other S/W do I need to get installed? I think by getting the vps I now have the chance to teach Enterprise Java and want to get into Java Message Server and Enterprise patterns. Can I get Glassfish installed or is that a silly question? What about servlets and beans? Thanks in anticipation Martin Rowe

• Nvidia optimus and Steam (on 12.04)

  - by Seiryuu

  I've obtained a copy of the .deb for the Steam beta, but it was pretty disappointing to see that it simply doesn't run. Hardware - Dell XPS L502, with Nvidia Optimus I have bumblebee installed. Trying to run Steam with the Intel HD 3000 completely fails to start it. Message received Installing breakpad exception handler for appid(steam)/version(1352224866_client) followed by a crash with no other information provided. Trying to optirun steam runs the client, but as soon as it gets to the home screen, it says that the Nvidia drivers I am using are out of date (and Steam requires newer drivers to run). It's probably worth to note that it throws the same Installing breakpad... error when run with optirun, but it doesn't crash the client immediately. Any way to fix this? Also, is there a way of manually updating the drivers in bumblebee without breaking anything? Alternatively, is there a reliable way of completely disabling the Intel GPU (in order to use the Nvidia GPU exclusively)? Note: I am using Xmonad with gnome-fallback, if that makes a difference. However, when I tried everything mentioned with Unity (2d), everything was the same, so I guess it has nothing to do with the window manager in use.

• Introduction to LinqPad Driver for StreamInsight 2.1

  - by Roman Schindlauer

  We are announcing the availability of the LinqPad driver for StreamInsight 2.1. The purpose of this blog post is to offer a quick introduction into the new features that we added to the StreamInsight LinqPad driver. We’ll show you how to connect to a remote server, how to inspect the entities present of that server, how to compose on top of them and how to manage their lifetime. Installing the driver Info on how to install the driver can be found in an earlier blog post here. Establishing connections As you click on the “Add Connection” link in the left pane you will notice that now it’s possible to build the data context automatically. The new driver appears as an option in the upper list, and if you pick it you will open a connection dialog that lets you connect to a remote StreamInsight server. The connection dialog lets you specify the address of the remote server. You will notice that it’s possible to pick up the binding information from the configuration file of the LinqPad application (which is normally in the same folder as LinqPad.exe and is called LinqPad.exe.config). In order for the context to be generated you need to pick an application from the server. The control is editable hence you can create a new application if you don’t want to make changes to an existing application. If you choose a new application name you will be prompted for confirmation before this gets created. Once you click OK the connection is created and you can start issuing queries against the remote server. If there’s any connectivity error the connection is marked with a red X and you can see the error message informing you what went wrong (i.e., the remote server could not be reached etc.). The context for remote servers Let’s take a look at what happens after we are connected successfully. Every LinqPad query runs inside a context – think of it as a class that wraps all the code that you’re writing. If you’re connecting to a live server the context will contain the following: The application object itself. All entities present in this application (sources, sinks, subjects and processes). The picture below shows a snapshot of the left pane of LinqPad after a successful connection. Every entity on the server has a different icon which will allow users to figure out its purpose. You will also notice that some entities have a string in parentheses following the name. It should be interpreted as such: the first name is the name of the property of the context class and the second name is the name of the entity as it exists on the server. Not all valid entity names are valid identifier names so in cases where we had to make a transformation you see both. Note also that as you hover over the entities you get IntelliSense with their types – more on that later. Remoting is not supported As you play with the entities exposed by the context you will notice that you can’t read and write directly to/from them. If for instance you’re trying to dump the content of an entity you will get an error message telling you that in the current version remoting is not supported. This is because the entity lives on the remote server and dumping its content means reading the events produced by this entity into the local process. ObservableSource.Dump(); Will yield the following error: Reading from a remote 'System.Reactive.Linq.IQbservable`1[System.Int32]' is not supported. Use the 'Microsoft.ComplexEventProcessing.Linq.RemoteProvider.Bind' method to read from the source using a remote observer. This basically tells you that you can call the Bind() method to direct the output of this source to a sink that has to be defined on the remote machine as well. You can’t bring the results to the LinqPad window unless you write code specifically for that. Compose queries You may ask – what's the purpose of all that? After all the same information is present in the EventFlowDebugger, why bother with showing it in LinqPad? First of all, What gets exposed in LinqPad is not what you see in the debugger. In LinqPad we have a property on the context class for every entity that lives on the server. Because LinqPad offers IntelliSense we in fact have much more information about the entity, and more importantly we can compose with that entity very easily. For example, let’s say that this code creates an entity: using (var server = Server.Connect(...)) {     var a = server.CreateApplication("WhiteFish");     var src = a         .DefineObservable<int>(() => Observable.Range(0, 3))         .Deploy("ObservableSource"); If later we want to compose with the source we have to fetch it and then we can bind something to     a.GetObservable<int>("ObservableSource)").Bind(... This means that we had to know a bunch of things about this: that it’s a source, that it’s an observable, it produces a result with payload Int32 and it’s named “ObservableSource”. Only the second and last bits of information are present in the debugger, by the way. As you type in the query window you see that all the entities are present, you get IntelliSense support for them and it’s much easier to make sense of what’s available. Let’s look at a scenario where composition is plausible. With the new programming model it’s possible to create “cold” sources that are parameterized. There was a way to accomplish that even in the previous version by passing parameters to the adapters, but this time it’s much more elegant because the expression declares what parameters are required. Say that we hover the mouse over the ThrottledSource source – we will see that its type is Func<int, int, IQbservable<int>> - this in effect means that we need to pass two int parameters before we can get a source that produces events, and the type for those events is int – in the particular case of my example I had the source produce a range of integers and the two parameters were the start and end of the range. So we see how a developer can create a source that is not running yet. Then someone else (e.g. an administrator) can pass whatever parameters appropriate and run the process. Proxy Types Here’s an interesting scenario – what if someone created a source on a server but they forgot to tell you what type they used. Worse yet, they might have used an anonymous type and even though they can refer to it by name you can’t figure out how to use that type. Let’s walk through an example that shows how you can compose against types you don’t need to have the definition of. This is how we can create a source that returns an anonymous type: Application.DefineObservable(() => Observable.Range(1, 10).Select(i => new { I = i })).Deploy("O1"); Now if we refresh the connection we can see the new source named O1 appear in the list. But what’s more important is that we now have a type to work with. So we can compose a query that refers to the anonymous type. var threshold = new StreamInsightDynamicDriver.TypeProxies.AnonymousType1_0<int>(5); var filter = from i in O1              where i > threshold              select i; filter.Deploy("O2"); You will notice that the anonymous type defined with this statement: new { I = i } can now be manipulated by a client that does not have access to it because the LinqPad driver has generated another type in its stead, named StreamInsightDynamicDriver.TypeProxies.AnonymousType1_0. This type has all the properties and fields of the type defined on the server, except in this case we can instantiate values and use it to compose more queries. It is worth noting that the same thing works for types that are not anonymous – the test is if the LinqPad driver can resolve the type or not. If it’s not possible then a new type will be generated that approximates the type that exists on the server. Control metadata In addition to composing processes on top of the existing entities we can do other useful things. We can delete them – nothing new here as we simply access the entities through the Entities collection of the application class. Here is where having their real name in parentheses comes handy. There’s another way to find out what’s behind a property – dump its expression. The first line in the output tells us what’s the name of the entity used to build this property in the context. Runtime information So let’s create a process to see what happens. We can bind a source to a sink and run the resulting process. If you right click on the connection you can refresh it and see the process present in the list of entities. Then you can drag the process to the query window and see that you can have access to process object in the Processes collection of the application. You can then manipulate the process (delete it, read its diagnostic view etc.). Regards, The StreamInsight Team

• Emacs saying: <M-kp-7> is undefined when dictating quotes with Dragon naturally speaking 12

  - by Keks Dose

  I dictating my text via Dragon Naturally Speaking 12 into Emacs. Whenever I say (translation from German): 'open quotes', I expect something like " or » to appear on the screen, but I simply get a message <M-kp-2> is undefined . Same goes for 'close quotes', I get <M-kp-7> is undefined. Does anybody know how to define those virtual keyboard strokes? (global-set-key [M-kp-2] "»") does not work.

• Should these concerns be separated into separate objects?

  - by Lewis Bassett

  I have objects which implement the interface BroadcastInterface, which represents a message that is to be broadcast to all users of a particular group. It has a setter and getter method for the Subject and Body properties, and an addRecipientRole() method, which takes a given role and finds the contact token (e.g., an email address) for each user in the role and stores it. It then has a getContactTokens() method. BroadcastInterface objects are passed to an object that implements BroadcasterInterface. These objects are responsible for broadcasting a passed BroadcastInterface object. For example, an EmailBroadcaster implementation of the BroadcasterInterface will take EmailBroadcast objects and use the mailer services to email them out. Now, depending on what BroadcasterInterface implementation is used to broadcast, a different implementation of BroadcastInterface is used by client code. The Single Responsibility Principle seems to suggest that I should have a separate BroadcastFactory object, for creating BroadcastInterface objects, depending on what BroadcasterInterface implementation is used, as creating the BroadcastInterface object is a different responsibility to broadcasting them. But the class used for creating BroadcastInterface objects depends on what implementation of BroadcasterInterface is used to broadcast them. I think, because the knowledge of what method is used to send the broadcasts should only be configured once, the BroadcasterInterface object should be responsible for providing new BroadcastInterface objects. Does the responsibility of “creating and broadcasting objects that implement the BroadcastInterface interface” violate the Single Responsibility Principle? (Because the contact token for sending the broadcast out to the users will differ depending on the way it is broadcasted, I need different broadcast classes—though client code will not be able to tell the difference.)

• xorg, nvidia, log-in all hosed - how can I completely reset graphics set-up/settings?

  - by Fred Hamilton

  I just did a fresh install of Mythbuntu 12.04.1 on my Intel MB with nVidia 9500GT graphics card. Hardware's been working great with 10.10 for about 2 years. Background: (optional - feel free to skip to question) I was trying to get my component video output to generate 720p, messing around with the nvidia drivers, and now the entire display system is hosed. I can SSH in and get a terminal. Depending on which nvidia package I install/remove, I get: Garbage on screen (after I "apt-get remove nvidia*") A low-res graphical log-in screen where I can log in as fred or guest. If I log in as fred, it displays some text mode status line then goes right back to the log-in screen. If I log in as guest, I actually get the full Ubuntu desktop, but I need to be able to log in as fred. Other times I get an error: "API mismatch: the NVIDIA kernel module has version 304.43, but this NVIDIA driver component has version 295.49." I've googled around, including trying this thread with the same error message, but to no effect. Question: How can I just reset x settings, drivers, everything display-related to the exact same way it was after a fresh install?

• Enabling AES 256 GCM on Windows Server 2012 R2

  - by Feanaro

  I'd like to enable the use of the AES 256 GCM encryption instead of the AES 256 CBC. We already have ECC certificates based on ECDSA so that pre-requisite has been fullfilled. The certificate has a SHA-256 signature and uses a 256-bit ECC keyset. The ciphersuite I'd like to use: TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384_P384 This is our ciphersuite order: TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384_P384, TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384_P521, TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384_P384, TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384_P521, TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA_P256, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA_P256, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384_P256 Still when I check the website it says we use TLS 1.2 and ECDHE_ECDSA for key exchange AES_256_CBC encryption and SHA1 for message digest. I suspect it uses this suite for some reason: TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA_P256 When I remove that ciphersuite the site has a protocol mismatch and won't load the https anymore. Does anyone know how to enable the ciphersuite? Did I forget to set something in the registry or do I need to do something else to enable that specific suite. Thanks in advance!

• Program error trying to generate Outlook 2013 email from Visual Basic 2010 [on hold]

  - by Dewayne Pinion

  I am using vb to send emails through outlook. Currently we have a mix of outlook versions at our office: 2010 and 2013 with a mix of 32 bit and 64 bit (a mess, I know). The code I have works well for Outlook 2010: Private Sub btnEmail_Click(sender As System.Object, e As System.EventArgs) Handles btnEmail.Click CreateMailItem() End Sub Private Sub CreateMailItem() Dim application As New Application Dim mailItem As Microsoft.Office.Interop.Outlook.MailItem = CType(application.CreateItem( _ Microsoft.Office.Interop.Outlook.OlItemType.olMailItem), Microsoft.Office.Interop.Outlook.MailItem) 'Me.a(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem) mailItem.Subject = "This is the subject" mailItem.To = "[email protected]" mailItem.Body = "This is the message." mailItem.Importance = Microsoft.Office.Interop.Outlook.OlImportance.olImportanceLow mailItem.Display(True) End Sub However, I cannot get this to work for 2013. I have referenced the version 15 dll for 2013 and it seems to be backward compatible, but when I try to use the above code for 2013 (it is 64 bit) it says it cannot start Microsoft Outlook. A program error has occured. This is happening on the application Dim statement line. I have tried googling around but there doesn't seem to be much out there referencing 2013 but I feel that the problem here probably has more to do with 64 bit than the software version. Thank you for any suggestions!

• kerberos5 unable to authenticate

  - by wolfgangsz

  We have a Debian file server, configured to serve up samba shares, using winbind and kerberos. This is configured to authenticate against a Windows2003 DC. All worked fine until recently when I did a maintenance update on all packages. Since then, all attempts to connect to any of the shares (and also to just log into the box) fail. The logs contain this message, which seems to be at the root of the evil: [2009/09/14 12:04:29, 10] libsmb/clikrb5.c:get_krb5_smb_session_key(685) Got KRB5 session key of length 16 [2009/09/14 12:04:29, 10] libsmb/clikrb5.c:unwrap_pac(280) authorization data is not a Windows PAC (type: 141) [2009/09/14 12:04:29, 3] libads/kerberos_verify.c:ads_verify_ticket(430) ads_verify_ticket: did not retrieve auth data. continuing without PAC From there on it fails to find the user account on the DC, subsequently remaps the user to user nobody and then (rightly) refuses to grant access to the share. However, the following works just fine: wbinfo -a user%password I was wondering whether anybody has had this problem and could provide some insight. I would be happy to provide neutralised config files.

• Why doesn't my sound card start? It reports code 10.

  - by Sarim Ali

  When I installed the XP for first time my sound card was working fine. But only after the first reboot it has stopped working. Under Device Manager, the section "sound video and game controller" the entry YAMAHA Native DS1 WDM Driver, has a exclamation mark on it. On left clicking and selecting properties it shows this message "This device cannot start. (Code 10)". On trying to update driver it says a better driver can not be found. Any idea how I can solve the issue? Update: As suggested by harrymc I uninstalled the device "YAMAHA Native DS1 WDM Driver" , and scanned for hardware changes. The windows detected and installed the soundcard and it started working properly.BUT, after restarting the same problem occurs. So, now everytime I reboot the computer I am stuck to, repeating the process of uninstalling the device to make it work.

• fsck: FILE SYSTEM WAS MODIFIED after each check with -c, why?

  - by Chris

  Hi I use a script to partition and format CF cards (connected with a USB card writer) in an automated way. After the main process I check the card again with fsck. To check bad blocks I also tried the '-c' switch, but I always get a return value != 0 and the message "FILE SYSTEM WAS MODIFIED" (see below). I get the same result when checking the very same drive several times... Does anyone know why a) the file system is modified at all and b) why this seems to happen every time I check and not only in case of an error (like bad blocks)? Here's the output: linux-box# fsck.ext3 -c /dev/sdx1 e2fsck 1.40.2 (12-Jul-2007) Checking for bad blocks (read-only test): done Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information Volume (/dev/sdx1): ***** FILE SYSTEM WAS MODIFIED ***** Volume (/dev/sdx1): 5132/245760 files (1.2% non-contiguous), 178910/1959896 blocks Thanks, Chris

  Hello, I'm looking to tweak ubuntu cloud version default setup where is denies root login. Attempting to connect to such machine yields: maxim@maxim-desktop:~/workspace/integration/deployengine$ ssh [email protected] The authenticity of host 'ec2-204-236-252-95.compute-1.amazonaws.com (204.236.252.95)' can't be established. RSA key fingerprint is 3f:96:f4:b3:b9:4b:4f:21:5f:00:38:2a:bb:41:19:1a. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added 'ec2-204-236-252-95.compute-1.amazonaws.com' (RSA) to the list of known hosts. Please login as the ubuntu user rather than root user. Connection to ec2-204-236-252-95.compute-1.amazonaws.com closed. I would like to know where this is setup and how I can change the printed message? Thank you, Maxim.

• Windows 7 Via Hyperion 4-1 drivers

  - by Gratzy

  I have a clean install of Win 7 on some relatively old hardware. Everything works pretty well however my cpu is pegged at 100% most of the time. Task Manager shows srvchost as being a main culprit of course but also system interrupts. I have a Biostar socket 478 MB with Via chipset. I have tried to find Windows 7 drivers for this but when I download and try to install what VIA/BIOSTAR say should be good for all OS's it will not load. I get a message saying can't find components for this OS. Anybody have any idea where I might find suitable drivers for the Chipset? BTW I'm not using the integrated graphics on the board but have a radeon 4500 pci-e card.

• How can I track a bug that caused a crash and was reported via apport / whoopsie?

  - by nealmcb

  It used to be that when a program crashed, especially when a user was using a pre-release of Ubuntu, apport could be used to open a bug report. The user could then track the bug, see if it affected others, help fix it, etc. As of Precise 12.04, this behavior and workflow changed. As I discovered in Bug #993450 “Apport fails to submit bug report”, by default apport no longer opens a bug report (and it is awkward but not impossible to get it to do so). At the same time people are noticing a new "whoopsie" process, as described at What is the 'whoopsie' process and what does it do?. After some more googling, I dug this blueprint up, which describes the whole process: ErrorTracker - Ubuntu Wiki. (It didn't mention whoopsie or daisy, so I added them - please correct me if I got it wrong). Wow - this sounds like great work to streamline and improve the crash reporting process. I'm left with this question: how does a user learn what the status of the problem is? The blueprint now has this requirement The user should have some way to check back on the status of their crash report; e.g. have some report ID they can look at to see statistics and/or any associated bug #. E.g. provide a serial number at time of filing that they can load via a web page later on. which seems unimplemented. Is there anything available in the meantime? And how does a developer get into the game? Going to https://daisy.ubuntu.com just provides an "Incorrect Content-Type" error message. Finally, I suggest documenting the apport behavior changes in the Release Notes. It should be of interest to anyone who has been trying to help out Ubuntu.

• Can't install Ubuntu on my Windows 7 laptop

  - by Ana

  I tried installing Ubuntu in two different ways: First, I tried the Windows Installer, and it goes well until I reboot the system and, when booting on Ubuntu, I get the error: No root file system defined. Second, I uninstalled wubi by going to to Control Panel - Uninstall Programs - Ubuntu. Then, I booted the laptop from the live CD and selected install. It boots okay but in the screen right after the one that says to make sure you have 4.5 GB available, Internet connection, etc, when I click continue it throws me a message saying that Ubuntu had an internal error and asks me if I want to report the error. After that, I just have a black screen and nothing else! No Ubuntu installed, no boot option to go back to Windows. Nothing! My goal is to install Ubuntu alongside Windows 7 (without the hassle of formatting the computer, creating partition, etc). How can I do it (preferable using Windows Installer)? How can I solve the "No root file system defined" that I encountered when I used the Windows Installer?

• Force apt to remove all emacs*

  - by wishi

  Hi! I have a bug-problem with the apt-packages of emacs: >>Error occurred processing debian-ispell.el: File error (("Opening input file" "no such file or directory" "/usr/share/emacs23/site-lisp/dictionaries-common/debian-ispell.el")) >>Error occurred processing ispell.el: File error (("Opening input file" "no such file or directory" "/usr/share/emacs23/site-lisp/dictionaries-common/ispell.el")) >>Error occurred processing flyspell.el: File error (("Opening input file" "no such file or directory" "/usr/share/emacs23/site-lisp/dictionaries-common/flyspell.el")) emacs-install: /usr/lib/emacsen-common/packages/install/dictionaries-common emacs23 failed at /usr/lib/emacsen-common/emacs-install line 28, <TSORT> line 30. dpkg: error processing emacs23-lucid (--configure): subprocess installed post-installation script returned error exit status 1 dpkg: dependency problems prevent configuration of emacs: emacs depends on emacs23 | emacs23-lucid | emacs23-nox; however: Package emacs23 is not installed. Package emacs23-lucid which provides emacs23 is not configured yet. Package emacs23-nox which provides emacs23 is not installed. Package emacs23-lucid is not configured yet. Package emacs23-nox is not installed. dpkg: error processing emacs (--configure): dependency problems - leaving unconfigured No apport report written because the error message indicates its a followup error from a previous failure. Errors were encountered while processing: emacs23-lucid emacs E: Sub-process /usr/bin/dpkg returned an error code (1) In fact I would be satisfied with just emacs23-nox, a couple of plugins - from apt. But I can neither --purge nor --purge reinstall, nor remove the packages. It always processes until this certain bug. I did some google-searching, found some stuff on Launchpad suggesting: sudo apt-get install --reinstall --purge emacsen-common But this is the same... so I hope there a way to tell app to just remove everything releated to emacs, and to start from scratch again? Thanks, Marius

• Mac OSX Server: svn via ssh command line and encrypted passwords.

  - by Ben Clayton

  Hi all. When I log into our mac mini server running OSX 10.6 via ssh and use svn I get the message: ATTENTION! Your password for authentication realm: can only be stored to disk unencrypted! You are advised to configure your system so that Subversion can store passwords encrypted, if possible. See the documentation for details. You can avoid future appearances of this warning by setting the value of the 'store-plaintext-passwords' option to either 'yes' or 'no' in '/Users/xxxxxxxx/.subversion/servers'. I dont' want to store the password unencrypted though. I've found some details on how to use GNOME keychain in linux to sort this, but nothing on how to use macosx's keychain. Anyone got any ideas? Thanks a lot!

• How can OpenGL graphics be displayed remotely using VNC?

  - by Jared Brown

  I am attempting to run a program that uses OpenGL to render a model in a viewport through VNC unsuccessfully. The error message I receive is - Xlib: extension "GLX" missing on display ":1.0". It was my understanding that VNC can be configured to render all graphics remotely and send a compressed screen grab from the display buffer to the local client. This would seem to negate the need for GLX extensions on the local client. Can VNC be configured this way and could you briefly describe how? Remote host: vncserver on RHEL 5 Local client: UltraVNC on Windows XP

• Iphone/Android app – chatroom development – what framework & hosting needs?

  - by MikaelW

  I have some experience regarding IPhone and Android development but I am now struggling to solve a new class of problem: apps that involve a client/server chatroom feature. That is, an app when people can exchange text over the internet, and without having the app to constantly “pull” content from the server. So that problem can’t be solved with a normal php/mysql website, there must be some kind of application running on a server that is able to send message from the server to the phone, rather than having the phone to check for new messages every 10 seconds… So I’m looking for ways to solve the different problems here: What framework should I use on the two sides (phone / server)? It should be some kind of library that doesn’t prevent me to write paid apps. It should also be possible to have the same server for the Iphone and android version of the app. What server / hosting solution do I need with what sort of features, I just have no experience regarding server application that can handle and initiate multiple connections and are hosted on hardware that is always online I tried to find resources online but couldn’t so far, either the libraries had the wrong kind of license/language or I just didn’t understand… Sometimes there were nice tutorial but for different needs such as peer2peer chat over local network… Same with the server and the hosting problem, not sure where to start really, I’m calling for help and I promise I will complete this page with notes about the experience I will get :-) Obviously the ideal would be to find a tutorial I missed that include client code, server code and a free scalable server… That being said, If I see something as good, it probably means that I have eaten the wrong kind of mushroom again… So, failing that, any pointer which might help me toward that quest, would be greatly appreciated. Thanks in advance. Mikael
