  • What is the difference between development and R&D?

    - by MainMa
    I was asked by a colleague to explain clearly the difference between ordinary development and research and development (R&D) and was unable to do it. After reading Wikipedia, I still don't have the precise answer. According to Wikipedia (slightly modified): There are two primary models: In one model, the primary function is to develop new products; in the other model, the primary function is to discover and create new knowledge about scientific and technological topics for the purpose of uncovering and enabling development of valuable new products, processes, and services. The first model is confusing. Does it mean that development (not R&D) consists exclusively in adding new features to a product, solving bugs and doing maintenance? What if something which was previously developed as a new feature becomes a separate product? The second model is less confusing, but still, how to qualify whether something is new knowledge or existent knowledge which is just rediscovered? Later, Wikipedia adds that ordinary development is different from R&D because of its: nearly immediate profit or immediate improvement. It's still not clear enough. How to qualify "nearly immediate profit"? What if a task has an immediate profit but requires heavy research? Or if it is basic but has uncertain profit, like the enforcement of a common style over the codebase? For example, does it belong to development or R&D to: Develop an engine which abstracts the access to the database, simplifying and shortening enormously the code of other applications (existent or ones which will be written in future) which should access to the database? Establish a new service-oriented architecture for the entire organization of company resources, in order to move from a bunch of separate and autonomous applications to a set of well-organized, interconnected web services, like what is used by Amazon? Design a new communication protocol to allow faster replication of data between two data centers of the company? Conceive a new type of software testing while working on a specific product, knowing that this type of testing will improve/simplify the testing process? Prove that Functional programming is more appropriate than OOP for a specific application, based on evidence, logic and previous experience? Enhance the existent application by adding gestures on tactile screens, after doing studies and testing that shows that those gestures improve the productivity of the users by a ratio of at least 1.4 for a precise set of tasks? Find a way to strongly enhance the Power usage effectiveness (PUE) of a data center? Create a Domain-Specific Language (DSL)? In short, how could I determine whether I'm doing R&D while working on something?

  • How to make changes in gconf-editor permanent

    - by Kristal
    Every time I open my computer, I need to manually unset the value of button_layout in gconf-editor in /apps/metacity/general to make to the close, minimize and maximize buttons on the right side of the window, but every time I restart my computer it changes back to the left side. I've tried to right-click the setting and choose "set as default" - but this doesn't work. How can I make this be permanent?

  • What are the differences between Bigloo and ECL?

    - by Pubby
    I've been looking to embed Lisp in some C++ code. Two options I'm interested in is Bigloo Scheme and ECL. Reading through the docs they seem to support a very similar feature set. Obviously Bigloo is Scheme and ECL is CLisp, but what other differences do they have? In particular I'm interested in the following criteria: Ease of embedding (for C++, not just C) Performance Style of coding Size Tail call support I'm targeting this question towards someone who has used both.

  • Unable to boot ubuntu 11.10 from external usb drive

    - by user45006
    I'm new to Ubuntu (and actually all things Linux) as of this morning, so please excuse any stupid mistakes I may be making. I recently bought an external hard drive for my newly built PC (that is running windows 7 if it matters). I would like to install Ubuntu onto the external drive and boot from there. I downloaded Ubuntu 11.10 and made a bootable cd, unplugged my internal HDDs, plugged in the external drive, installed Ubuntu 11.10 on the external drive via the installer, and replugged in my internal HDDs. Then I set my bios boot order to: Boot from USB-HDD - Boot from Hard Disk - Boot from CD/DVD. Now when I restart I get the message "Starting Operating System..." (or something like that, I forget exactly what it says) that lingers on the screen for a moment and then windows starts. Any idea what the problem may be? ~Relevant info~ BIOS version: Award Software International, Inc. F2, 2/22/2011 Ubuntu Version: 11.10 External Hard Drive: Western Digital My Passport Essential 500GB Portable Hard Drive (Black) ~Things I've already tried~ 1) Unplug internal HDDs so that only external drive was plugged in via usb. Same thing happened only obviously my BIOS could not detect any hard drives besides the external one. When booting received error "Could not detect operating system" 2) Formatted external hard drive and re installed. It didn't make a difference, however interestingly when I booted from cd the ubuntu installer said it detected ubuntu 11.10 on the external hard drive. 3) Within BIOS I've messed around with every boot order combo I could think of both in the "Hard Disk boot order" screen and the "Boot order" screen. I'm a little confused of why there are two screens for this. 4) Held F12 during startup which opens (what I think is) the one time boot screen and it gave me the options "Hard Drive", "cd/dvd", "USB-FDD", "USB-cdrom", "USB-HDD", and "USB-something else I can't remember what it was". I tried all of them, but the same thing as before happened each time. ~References~ I noticed several people on askubuntu have tried to do something similar if not the exact same. In fact, I even found a post that pretty much outlines step by step exactly what I did... only their's worked. /jealous. Linky: Install Ubuntu or Kubuntu on a External USB Drive I'm willing to try a different version of ubuntu - it's not like my heart is set on 11.10, but it's a pain to open my case and unplug my internal hard drives so I'd prefer not to do this unless someone is reasonably confident it'll work. Thank you for all of your help in advance! I'm really looking forward to exploring Ubuntu!

  • Enum types, FlagAttribute & Zero value

    - by nmgomes
    We all know about Enums types and use them every single day. What is not that often used is to decorate the Enum type with the FlagsAttribute. When an Enum type has the FlagsAttribute we can assign multiple values to it and thus combine multiple information into a single enum. The enum values should be a power of two so that a bit set is achieved. Here is a typical Enum type: public enum OperationMode { /// <summary> /// No operation mode /// </summary> None = 0, /// <summary> /// Standard operation mode /// </summary> Standard = 1, /// <summary> /// Accept bubble requests mode /// </summary> Parent = 2 } In such scenario no values combination are possible. In the following scenario a default operation mode exists and combination is used: [Flags] public enum OperationMode { /// <summary> /// Asynchronous operation mode /// </summary> Async = 0, /// <summary> /// Synchronous operation mode /// </summary> Sync = 1, /// <summary> /// Accept bubble requests mode /// </summary> Parent = 2 } Now, it’s possible to do statements like: [DefaultValue(OperationMode.Async)] [TypeConverter(typeof(EnumConverter))] public OperationMode Mode { get; set; } /// <summary> /// Gets a value indicating whether this instance supports request from childrens. /// </summary> public bool IsParent { get { return (this.Mode & OperationMode.Parent) == OperationMode.Parent; } } or switch (this.Mode) { case OperationMode.Sync | OperationMode.Parent: Console.WriteLine("Sync,Parent"); break;[…]  But there is something that you should never forget: Zero is the absorber element for the bitwise AND operation. So, checking for OperationMode.Async (the Zero value) mode just like the OperationMode.Parent mode makes no sense since it will always be true: (this.Mode & 0x0) == 0x0 Instead, inverse logic should be used: OperationMode.Async = !OperationMode.Sync public bool IsAsync { get { return (this.Mode & ContentManagerOperationMode.Sync) != ContentManagerOperationMode.Sync; } } or public bool IsAsync { get { return (int)this.Mode == 0; } } Final Note: Benefits Allow multiple values combination The above samples snippets were taken from an ASP.NET control and enabled the following markup usage: <my:Control runat="server" Mode="Sync,Parent"> Drawback Zero value is the absorber element for the bitwise AND operation Be very carefully when evaluating the Zero value, either evaluate the enum value as an integer or use inverse logic.

  • Problem using Skype Screenshare on dual monitors

    - by toobsco42
    I am on Ubuntu 12.04 and when using the screenshare feature of Skype 4.0 on a single monitor I dont have an issue. However as soon as i switch to using dual monitors and try to set up a screenshare, it doesn't work. Does anyone know if this is a known bug in the Skype app? Thanks. Apparently Skype's log files are encrypted, and they recommend just sending the log files to them so that they can determine how to resolve the issue.

  • More Oracle VM templates for PeopleSoft and Oracle Enteprise Manager

    - by wcoekaer
    Just as I wrote up a blog promoting the Oracle VM Ebusiness suite templates, we also pushed out 2 other products : Oracle Enterprise Manager Cloud Control 12c Oracle PeopleSoft FSCM 9.1 and PeopleTools 8.52.03 They can be downloaded from edelivery. Same advantage... you download the template, import it and you have a completely pre-installed set of products. That's application deployment, not just VM deployment. That's flexibility across the stack, not just a hypervisor, not just virtualization, but a complete solution stack.

  • Some Oracle VM 3 updates

    - by wcoekaer
    Today we did another patch set update for Oracle VM 3 (3.0.3-build 227). This can be downloaded from My Oracle Support as patch ID 14736185. There are quite a few updates in here and I highly recommend any Oracle VM 3 customer or user to install this update. This patch can be installed on top of Oracle VM 3.0 versions 3.0.2 and 3.0.3. The patch is cumulative for 3.0.3. So if you already installed patch update 1 (3.0.3-150) then this will just be incremental on top of that and brings you to 3.0.3-build 227. There is a readme file which contains the patchlist in the patch info. The following patches are released on ULN for Oracle VM server 3.0 : initscripts-8.45.30-2.100.18.el5.x86_64 The inittab file and the /etc/init.d scripts. kernel-ovs-2.6.32.21-45.6.x86_64 The Linux kernel kernel-ovs-firmware-2.6.32.21-45.6.x86_64 Firmware files used by the Linux kernel osc-oracle-ocfs2-0.1.0-35.el5.noarch Oracle Storage Connect ocfs2 Plugin osc-plugin-manager-1.2.8-9.el5.3.noarch Oracle Storage Connect Plugin Infrastructure osc-plugin-manager-devel-1.2.8-9.el5.3.noarch Oracle Storage Connect Plugin Development ovs-agent-3.0.3-41.6.x86_64 Agent for Oracle VM xen-4.0.0-81.el5.1.x86_64 Xen is a virtual machine monitor xen-devel-4.0.0-81.el5.1.x86_64 Development libraries for Xen tools xen-tools-4.0.0-81.el5.1.x86_64 Various tooling for the manipulation of Xen instances Errata emails will be sent in the next few days with details on the above updates. Or you will find them here. I also did an update of my Oracle VM utilities to 0.4.0. They are also available from My Oracle Support, patch ID 14736239. These utils can be unzipped and installed on the server running Oracle VM Manager. Typically in /u01/app/oracle/ovm-manager-3/ovm_utils. There is a set of man pages in /u01/app/oracle/ovm-manager-3/ovm_utils/man/man8. There now are 6 commands : ovm_vmcontrol : VM level operations ovm_servercontrol : server level operations ovm_vmdisks : virtual disk/physical location mapping for VM disks ovm_vmmessage : message passing utility between the manager and the VM tools (in the Oracle VM templates) ovm_repocontrol : repository level operations ovm_poolcontrol : pool level operations Some of the new changes : at a pool level, acknowledge events and cascade to servers and virtual machines with outstanding events at a pool level, do a rescan of the storage for fibrechannel/iscsi disks if you add new devices (it does this operation then on every running server) at a repository level, fixup a device if it had a failed create repository at a repository level, refresh the repository and this will update the free space in the UI for ocfs2 repositories at a server level, acknowledge server events and cascade to virtual machines if needed at a VM level, acknowledge VM events at a VM level, bind vcpus to cores with vcpuset/vcpuget Please see the man pages and remember that these tools are just written As Is - no SRs... (per the documentation) Hopefully they are useful.

  • How I Work: Staying Productive Whilst Traveling

    - by BuckWoody
    I travel a lot. Not like some folks that are gone every week, mind you, although in the last month I’ve been to: Cambridge, UK; Anchorage, AK; San Jose, CA; Copenhagen, DK, Boston, MA; and I’m currently en-route to Anaheim, CA.  While this many places in a month is a bit unusual for me, I would say I travel frequently. I’ve travelled most of my 28+ years in IT, and at one time was a consultant traveling weekly.   With that much time away from my primary work location, I have to find ways to stay productive. Some might say “just rest – take a nap!” – but I’m not able to do that. For one thing, I’m a very light sleeper and I’ve never slept on a plane - even a 30+ hour trip to New Zealand in Business Class - so that just isn’t option. I also am not always in the plane, of course. There’s the hotel, the taxi/bus/train, the airport and then all that over again when I arrive. Since my regular jobs have many demands, I have to get work done.   Note: No, I’m not always focused on work. I need downtime just like everyone else. Sometimes I just think, watch a movie or listen to tunes – and I give myself permission to do that anytime – sometimes the whole trip. I have too fewheartbeats left in life to only focus on work – it’s just not that important, and neither am I. Some of these tasks are letters to friends and family, or other personal things. What I’m talking about here is a plan, not some task list I have to follow. When I get to the location I’m traveling to, I always build in as much time as I can to ensure I enjoy those sights and the people I’m with. I would find traveling to be a waste if not for that.   The Unrealistic Expectation As I would evaluate the trip I was taking – say a 6-8 hour flight – I would expect to get 10-12 hours of work done. After all, there’s the time at the airport, the taxi and so on, and then of course the time in the air with all of the room, power, internet and everything else I needed to get my work done. I would pile up tasks at home, pack my bags, and head happily to the magical land of the TSA.   Right. On return from the trip, I had accomplished little, had more e-mails and other work that had piled up, and I was tired, hungry, and unorganized. This had to change. So, I decided to do three things: Segment my work Set realistic expectations Plan accordingly  Segmenting By Available Resources The first task was to decide what kind of work I could do in each location – if any. I found that I was dependent on a few things to get work done, such as power, the Internet, and a place to sit down. Before I fly, I take some time at home to get all of the work I’d like to accomplish while away segmented into these areas, and print that out on paper, which goes in my suit-coat pocket along with a mechanical pencil. I print my tickets, and I’m all set for the adventure ahead. Then I simply do each kind of work whenever I’m in that situation. No power There are certain times when I don’t have power available. But not only that, I might not even be able to use most of my electronics. So I now schedule as many phone calls as I can for the taxi/bus/train ride and the airports as I can. I have a paper notebook (Moleskine, of course) and a pencil and I print out any notes or numbers I need prior to the trip. Once I’m airborne or at the airport, I work on my laptop. I check and respond to e-mails, create slides, write code, do architecture, whatever I can.  If I can’t use any electronics, or once the power runs out, I schedule time for reading. I can read at the airport or anywhere, actually, even in-flight or any other transport. I “read with a pencil”, meaning I take a lot of notes, which I liketo put in OneNote, but since in most cases I don’t have power, I use the Moleskine to do that. Speaking of which, sometimes as I’m thinking I come up with new topics, ideas, blog posts, or things to teach in my classes. Once again I take out the notebook and write it down. All of these notes get a check-mark when I get back to the office and transfer the writing to OneNote. I’ve tried those “smart pens” and so on to automate this, but it just never works out. Pencil and paper are just fine. As I mentioned, sometime I just need to think. I’ll do nothing, and let my mind wander, thinking of nothing in particular, or some math problem or science question I’m interested in. My only issue with this is that I communicate tothink, and I don’t want to drive people crazy by being that guy that won’t shut up, so I think in a different way. Power, but no Internet or Phone If I have power but no Internet or phone, I focus on the laptop and the tablet as before, and I also recharge my other gadgets. Power, Internet, Phone and a Place to Work At first I thought that when I arrived at the hotel or event I could get the same amount of work done that I do at the office. Not so. There’s simply too many distractions, things you need, or other issues that allow this. Of course, Ican work on any device, read, think, write or whatever, but I am simply not as productive as I am in my home office. So I plan for about 25-50% as much work getting done in this environment as I think I could really do. I’ve done some measurements, and this holds out to be true almost every time. The key is that I re-set my expectations (and my co-worker’s expectations as well) that this is the case. I use the Out-Of-Office notices to let people know that I’m just not going to be 100% at this time – it’s hard for everyone, but it’s more honest and realistic, and I’d rather they know that – and that I realize that – than to let them think I’m totally available. Because I’m not – I’m traveling. I don’t tend to put too much detail, because after all I don’t necessarily want to let people know when I’m not home :) but I do think it’s important to let people that depend on my know that I’ll get back with them later. I hope this helps you think through your own methodology of staying productive when you travel. Or perhaps you just go offline, and don’t worry about any of this – good for you! That’s completely valid as well.   (Oh, and yes, I wrote this at 35K feet, on Alaska Airlines on a trip. :)  Practice what you preach, Buck.)

  • Wvdial randomly drops 3G connection - How to auto-reconnect?

    - by askvictor
    I'm using a 3G modem for a router running Ubuntu server 10.04. I have the connection established using wvdial, which works successfully, but sometimes the connection drops. I would like it to auto re-connect. I've set the "auto reconnect" in wvdial.conf, but this does not seem to work. Any ideas? Am I missing a config option, or should I try writing a script which polls the network status and resets if ppp0 has gone down?

Could that be it? If not, could someone explain why this doesn't work. Please and thank you

  • Applying Quotas Across all My Sites

    - by Bil Simser
    Just a quick snippet this morning. If you need to apply a new quota template to all users My Sites here's a quick script to do it. Changing an existing quota is fine but if you're migrating users from another system or you just want to up everyone's storage a bit here's what you do. Create a new quota template. This is found in Central Admin under Application Management | Site Collections | Specify quota templates. There's already a default "Individual Quota" created you might want to create your own or have a special one for your users Open up the PowerShell Management Console and enter "Get-SPWebApplication". This will list all your web applications on the farm.  To apply it to all My Sites (each site is a site collection of its own) run this script below. .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: Consolas, "Courier New", Courier, Monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } 1: $webapps = Get-SPWebApplication; 2:   3: $webapp = $webapps[4]; 4:   5: foreach ($site in $webapp.Sites) { 6: Set-SPSite -Identity $site.url -QuotaTemplate "Your Quota Template" 7: } The first line gets all the web applications on the server. In our case, the forth one is the mysite web app (yours will probably be a different number). Just run Get-SPWebApplication from the console to figure out which one to use. You could get fancy and pipe the name to find it but I'm too lazy for that.Then we loop through all the sites on the list using the $site.url property and pass it to the Set-SPSite cmdlet and specify the name of the our custom QuotaTemplate.Easy. Now all users are updated with the new quota template.

  • What does it take to successfully run a URL shortener service [on hold]

    - by MxyL
    What are the costs (technology wise) for running a URL shortener service such as bit.ly or anonym.to? For example, if I decided to use an inexpensive shared hosting with "unlimited" bandwidth, would that be feasible? Or would I need a dedicated hosting? I found this question: I want to run a URL shortener for my own usage, what do I need to do?, which makes it easy to set it up, but I'm not too clear what kind of things I need to consider.

  • Content Based Routing with BRE and ESB

    - by Christopher House
    I've been working with BizTalk 2009 and the ESB toolkit for the past couple of days.  This is actually my first exposure to ESB and so far I'm pleased with how easy it is to work with. Initially we had planned to use UDDI for storing endpoint information.  However after discussing this with my client, we opted to look at BRE instead of UDDI since we're already storing transforms in BRE.  Fortunately making the change to BRE from UDDI was quite simple.  This solution of course has the added advantage of not needing to go through the convoluted process of registering our endpoints in UDDI. The first thing to remember if you want to do content based routing with BRE and ESB is that the pipleines included in the ESB toolkit don't include disassembler components.  This means that you'll need to first create a custom recieve pipeline with the necessary disassembler for your message type as well as the ESB components, itinerary selector and dispather. Next you need to create a BRE policy.  The ESB.ContextInfo vocabulary contains vocabulary links for the various items in the ESB context dictionary.  In this vocabulary, you'll find an item called Context Message Type, use this as the left hand side of your condition.  Set the right hand side to your message type, something like http://your.message.namespace/#yourrootelement.  Now find the ESB.EndPointInfo vocabulary.  This contains links to all the properties related to endpoint information.  Use the various set operators in your rule's action to configure your endpoint. In the example above, I'm using the WCF-SQL adapter. Now that the hard work is out of the way, you just need to configure the resolver in your itinerary. Nothing complicated here.  Just select BRE as your resolver implementation and select your policy from the drop-down list.  Note that when you select a policy, the Version field will be automatically filled in with the version of your policy.  If you leave this as-is, the resolver will always use that policy version.  Alternatively, you can clear the version number and the resolver will use the highest deployed version.

  • Telesharp – An Application Repository for .NET applications

    - by cibrax
    A year ago, we released SO-Aware as our first product in Tellago Studios. SO-Aware represented a new way to manage web services and all the related artifacts like configuration, tests or monitoring data in the Microsoft stack. It was based on the idea of using a lightweight SOA governance approach with a central repository exposed through RESTful services. At that point, we thought the same idea could be extended to enterprise applications in general by providing a generic repository for many of the runtime or design time artifacts generated during the development like configuration, application description or topology (a high level view of the components that made up a system), logging information or binaries. It took us several months to give a form to that idea and implement it as a product, but it is finally here and I am very proud to announce the release today under the name of “TeleSharp”. Telesharp provides in a nutshell the following features, 1. Configure your application topology in a central repository. Application topology in this context means that you can decompose your application and describe it in terms of components and how they interact each other. For example, you can tell that the CRM system is made up of a couple of WCF services and a ASP.NET MVC front end. 2. Centralize configuration for your applications and components.  You can import existing .NET configuration sections into the repository and associate them to the different components. In addition, environment overrides are supported for the configuration sections. We provide tooling and extensions in Visual Studio for managing all the configuration, and a set of powershell commands for automating the configuration deployment. 3. Browse all the assemblies and types remotely in your application servers in a web browser using an interface similar to any of the existing .NET reflection tools. You can easily determine this way whether the server is running the correct version of your applications. 4. Centralize logging and exception management into the repository. You get different reports and a pivot viewer experience for browsing all the different logging information generated by your applications. In addition, TeleSharp provides different providers for pushing the logging information to the central repository using well-known frameworks like ELMAH, Log4Net, EntLib or even Windows ETW.  The central repository itself is implemented as a set of OData services that any application can easily consume using regular Http. You can read more details in this introductory post If you think this product can be a good fit in your organization, you can request a trial version in our Tellago Studios website.

  • Reporting on common code smells : A POC

    - by Dave Ballantyne
    Over the past few blog entries, I’ve been looking at parsing TSQL scripts in a variety of ways for a variety of tasks.  In my last entry ‘How to prevent ‘Select *’ : The elegant way’, I looked at parsing SQL to report upon uses of SELECT *.  The obvious question leading on from this is, “Great, what about other code smells ?”  Well, using the language service parser to do that was turning out to be a bit of a hard job,  sure I was getting tokens but no real context.  I wasn't even being told when an end of statement had been reached. One of the other parsing options available from Microsoft is exposed in the assembly ‘Microsoft.SqlServer.TransactSql.ScriptDom’,  this is ,I believe, installed with the client development tools with SQLServer.  It is much more feature rich than the original parser I had used and breaks a TSQL script into intuitive classes for analysis. So, what sort of smells can I now find using it ?  Well, for an opening gambit quite a nice little list. Use of NOLOCK Set of READ UNCOMMITTED Use of SELECT * Insert without column references Explicit datatype conversion on Sargs Cross server selects Non use of two-part naming convention Table and Query hint usage Changes in set options Use of single line comments Use of ordinal column positions in ORDER BY clause Now, lets not argue the point that “It depends” as smells on some of these, but as an academic exercise it is quite interesting.  The code is available from this link :https://www.dropbox.com/s/rfk32sou4fzl2cw/TSQLDomTest.zip  All the usual disclaimers apply to this code, I cannot be held responsible for anything ranging from mild annoyance through to universe destruction due to the use of this code or examples. The zip file contains a powershell script and my test cases.  The assembly used requires .Net 4 to run, which means that you will need powershell 3 ( though im running through PowerGUI and all works ok ) .  The code searches for all .sql files in the folder hierarchy for the workingpath,  you can override this if you want by simply changing the $Folder variable, and processes each in turn for the smells.  Feedback is not great at the moment, all it does is output to an xml file (Smells.xml) the offset position and a description of the smell found. Right now, I am interested in your feedback.  What do you think ?  Is this (or should it be) more than an academic exercise ?  Can tooling such as this be used as some form of code quality measure ?  Does it Work ? Do you have a case listed above which is not being reported ? Do you have a case that you would love to be reported ? Let me know , please mailto: [email protected]. Thanks

  • Cloud service and IM protocol advice, for a backend to group chat mobile app

    - by Jonathan
    Overview I’m going to develop an app on Android and iOS. It will allow users to set up group ‘chat rooms’ and talk on chat rooms set up by other users. The service needs to be highly scalable, such that it could accommodate a massive increase in users overnight (we can only dream). Chat requirements The chat protocol used should be flexible: it should allow me to determine who can view/post on ‘chat rooms’ based on certain other factors, as determined by the first poster/creator of the particular ‘chat room’. It should also allow for users to simply install the app and begin using the service, after only providing a simple nickname (which could be changed later). Chat protocol plans Having looked around I think the XMPP protocol is the best candidate. In particular the Multi-user chat extension looks like what I’ll need. Would this be most suited to my requirements, or do you know another potential solution? Cloud service I have been deciding between Amazon Web Services, Google App Engine and Windows Azure. I’m coming to the conclusion that Azure will be best, as it is easier to manage than AWS (ease of scalability will be a key factor in the design), I think it may be less restricted than GAE, plus Azure will soon have toolkits to allow easy interfacing with both Android and iOS phones. Is this the decision you would have made, or would you recommend/look into other cloud services? General project philosophy I have only recently started looking into this project’s feasibility, and am no expert on any of its aspects. So wherever possible I will leave the actual implementations to experts, i.e. choosing a higher-level cloud service, using a well-documented plugin of a, proven reliable, group chat protocol etc. My background I have some programming knowledge from a computer science degree. Main languages I’ve used have been Java and Python, but I don’t want this to affect design decisions for the project. The most appropriate languages for the task should be used, i.e. I don’t mind learning a lot of new skills (my current programming levels are relatively basic anyway). Thank you Thanks for reading, and any advice you have about any aspect would be greatly appreciated :-)
