• Want to book hotel stay using Bitcoin? Book using Expedia.com

  - by Gopinath

  The online travel booking leader Expedia announced that it started accepting Bitcoins for booking hotels on its website. For those who are new to Bitcoin, it is a digital currency in which transactions can be performed without the need for a central bank – its more like internet of currency. At the moment Expedia is accepting Bitcoin payments only for hotel bookings and in the future it may allow flights and vacation packages bookings. When Expedia customers wants to pay for a hotel using Bitcoin then they are transferred to Coinbase, a third party bit coin processor, for accepting the payments and then they are redirected back to Expedia.com to complete booking. This simple process would definitely drive mainstream adoption of Bitcoin – a win-win situation for digital currency users as well as for the travel company as they save a lot on card processing fees. Online retailers pay around 3% of transaction amount as fees for credit card processing companies like Visa & Master when they accept cards, but Coinbase charges a fee of just 1 percent for processing Bitcoins. Irrespective of customers adoption to Bitcoin based payments on Expedia as well as the savings on transaction fees, this move would give bragging rights to Expedia being the first e-commerce giant to accept digital currency!

• Are project managers useful in Scrum?

  - by Martin Wickman

  There are three roles defined in Scrum: Team, Product Owner and Scrum Master. There is no project manager, instead the project manager job is spread across the three roles. For instance: The Scrum Master: Responsible for the process. Removes impediments. The Product Owner: Manages and prioritizes the list of work to be done to maximize ROI. Represents all interested parties (customers, stakeholders). The Team: Self manage its work by estimating and distributing it among themselves. Responsible for meeting their own commitments. So in Scrum, there is no longer a single person responsible for project success. There is no command-and-control structure in place. That seems to baffle a lot of people, specifically those not used to agile methods, and of course, PM's. I'm really interested in this and what your experiences are, as I think this is one of the things that can make or break a Scrum implementation. Do you agree with Scrum that a project manager is not needed? Do you think such a role is still required? Why?

• New cloud development workflow using Github, Cloud9ide and CloudFoundry.

  - by weng

  So time is changing towards cloud development/computing. I'm trying to get the new "cloud" workflow based on the services I'm going to use: Github, Cloud9ide and CloudFoundry. Here is what is on my mind: Github acts like a central (main repo) just like yesterday's local filesystem. Every service will base it service upon this main repo. Workflow: Github: I create a new Github repo served as main repo for the project. Cloud9ide. I open my Github repo and write my tests and implementation (BDD/TDD). When I'm ready I save (commit) it to main repo on Github. X: A running instance of Jenkins detects someone has committed and fetches the latest commit, builds, deploys, tests (yeti and/or selenium) and reports if the tests were passed or not. If not, I make another commit til all tests are passing. X: I run the CloudFoundry commands to push the main Github repo to CloudFoundry's server and it will deploy my app automatically. What I'm still confused about is where this X environment will be. On a local server where I have to install Jenkins? Or could I install it on Cloud9ide (when java is supported) or will it be on another cloud service? Also, that X environment has to be able to fetch (clone) the Github repo and run the build scripts. And since the concept of Cloud9ide is very new and there haven't been any other predecessors I really wonder how the workflow will look like. We all know Github's workflow. We now know CloudFoundry's workflow (deploy/scale with a restful API/command line tool). But how Cloud9Ide will operate is still somewhat unclear to me. Someone on Cloud9ide mentioned that there will be buttons like deploy so I can deploy with one click. But that I guess will depend on what services that deploy process will hook up into etc. Could someone enlighten this cloud workflow topic and fill in the gaps. Thanks.

• Missing /dev/xconsole causes rsyslog to stop as well as all other services

  - by George Van Tuyl

  We are running Ubuntu-10.04.04LTS in Hyper-V environments. We found that the services ssh http or anything else stopped because the rsyslog daemon had died with the message unable to find the /dev/xconsole file. I fixed it temporarily with the following. FILE=/dev/xconsole if [ -e $FILE ]; then echo "$FILE exists Carry on!" else mknod -m 640 /dev/xconsole c 1 3 chown syslog:adm /dev/xconsole echo "Created $FILE." fi The problem is that I can not get rsyslog daemon to process these 8 lines when I restart the daemon. Also restarting the daemon removes the /dev/xconsole file and we are back to all service stopped. In addressing this problem I have inserted the if--fi lines after the start and restart conditions in the rsyslog script. The problem is I do not get an echo to stdio. Does someone have an idea on how to make the rsyslog report to stdio when it creates the /dev/xconsole device. Thanks George Van Tuyl

• Fix Package is in a very bad inconsistent state

  - by Benjamin Piller

  I can't update my system because it freezes while installing a third-party update (zramswap-enabler)!! Sometimes I get the following message in Update manager: Could not initialize the package information An unresolvable problem occurred while initializing the package information. Please report this bug against the 'update-manager' package and include the following error message: E:The package zramswap-enabler needs to be reinstalled, but I can't find an archive for it. I tried to remove the zramswap-enabler, but it's impossible because I get the following message: dpkg: error processing zramswap-enabler (--remove): Package is in a very bad inconsistent state - you should reinstall it before attempting a removal. Errors were encountered while processing: zramswap-enabler E: Sub-process /usr/bin/dpkg returned an error code (1) Actually i would really reinstall that package, but it is unable to do it! If i remove this third-party PPA then the system is warning me about a very very serious problem. So why can i not install/reinstall/remove/update this package and why freezes the updater if i try to update? -S O L U T I O N-: Okay! Finally i found the solution for this Problem! Step 1. Make sure that your PPA is correctly Step 2. Remove the broken package via the following command: sudo dpkg --remove --force-remove-reinstreq zramswap-enabler Step 3. install the package again (sudo apt-get install zramswap-enabler) Step 4. After restart (not necessary) you are able to install the updates correctly! Actually you can fix any "Package is in a very bad inconsistent state” Issues with this solution!!!

• How can I use a batch shortcut to open multiple Windows Explorer folders, and a Notepad file?

  - by ModelHX

  I've recently built a computer with an SSD in it (my first) and am in the process of moving a select few of my Steam games to the SSD and symbolically linking them to where they're supposed to be on the main (mechanical) hard drive so that Steam doesn't throw a fit and I get maximum performance. To this end, I'm finding myself repeatedly navigating to both target folders to move the relevant files and opening a specific Notepad file to enter the relevant paths into a template I've got set up that I paste into the Windows command prompt to create the symlink. This is annoying. I've read up a little bit on batch shortcuts, and have a basic understanding on how to use one to open programs and files. However, I'm finding a lot of confusing suggestions on how to use batch shortcuts to open specific folders in Windows Explorer, and none of them deal with opening multiple folders at once. Any assistance on writing the shortcut would be greatly appreciated. Thank you for your time.

• Starting/Stopping IBM WebSphere Application Server (WAS) 7 from the Command Line

  - by Christopher Parker

  I've written a script to automate the process of starting, stopping, and restarting WAS7 from the command line. Nothing starts automatically on one of our staging servers, so I have to start everything: deployment manager, node agent, app server, and Web server. The script I wrote seems to work pretty well. A coworker of mine recommended that I structure my commands differently. I'm wondering if there's a good, valid reason for doing so. First, my variables: WAS_HOME="/opt/IBM/WebSphere/AppServer" WAS_PROFILE_NAME="AppSrv01" WAS_APP_SERVER="server1" WAS_WEB_SERVER="webserver1" How I had the start commands: "${WAS_HOME}/bin/startManager.sh" "${WAS_HOME}/bin/startNode.sh" -profileName $WAS_PROFILE_NAME "${WAS_HOME}/bin/startServer.sh" -profileName $WAS_PROFILE_NAME $WAS_APP_SERVER "${WAS_HOME}/bin/startServer.sh" -profileName $WAS_PROFILE_NAME $WAS_WEB_SERVER I was told that I should do it like this, instead: WAS_DMGR="Dmgr01" # Added variable "${WAS_HOME}/profiles/${WAS_PROFILE_NAME}/bin/startNode.sh" "${WAS_HOME}/profiles/${WAS_DMGR}/bin/startManager.sh" "${WAS_HOME}/profiles/${WAS_PROFILE_NAME}/bin/startServer.sh" $WAS_APP_SERVER "${WAS_HOME}/profiles/${WAS_PROFILE_NAME}/bin/startServer.sh" $WAS_WEB_SERVER How is the second way of starting up everything for WebSphere any better or more correct than the first, original, way?

• Hot fix published for TFS2010 upgrade issues

  - by jehan

  Microsoft has released a hot fix for the issues that are identified after the migration of TFS2005/TFS2008 servers to TFS2010. The issues are related to Merging and Labels: ·         Labels that were created before the upgrade are entirely empty.  Labels could be also have incorrect contents. ·         The merge wizard in Visual Studio does not display all valid merge targets for a given source path/branch. ·         During merging, merge candidates are shown for changes that were already merged prior to the upgrade. If you have not yet upgraded to TFS 2010, the hotfix is now available and is highly recommended to be applied before configuring your team project collections. Because this hotfix applies to the upgrade of version control content, it must be applied after TFS 2010 setup is complete, but before configuration is started.  At the end of the setup experience, the Success screen is shown indicating the completion of the installation.  Normally, users will continue on to the configuration part, but in this case, the user need to cancel the configuration part by un-checking the “Launch Team Foundation Server Configuration Tool” box, which will enable the Cancel button. After exiting setup, the hotfix executable can be run to update the upgrade steps. Once the hotfix is installed, the TFS Configuration Wizard will need to be re-launched from the Start Menu to complete the upgrade process.    The hotfix has been published on MSDN Code Gallery – you can find it here: http://code.msdn.microsoft.com/KB2135068   If you have upgraded to TFS2010 and facing any of the above issues, then checkout this KB for Resolution: http://support.microsoft.com/kb/2193796/en-us

• Prevent Eclipse Java Builder from Compiling Java-Like Source

  - by redjamjar

  I'm in the process of writing an eclipse plugin for my programming language Whiley (see http://whiley.org). The plugin is working reasonably well, although there's lots to do. Two pieces of the jigsaw are: I've created a "Whiley Builder" by subclassing incremental project builder. This handles building and cleaning of "*.whiley" files. I've created a content-type called "Whiley Source Files" for "*.whiley" files, which extends "org.eclipse.jdt.core.javaSource" (this follows Andrew Eisenberg suggestion). The advantage of having the content-type extend javaSource is that it immediately fits into the package explorer, etc. In principle, I could fleshout ICompilationUnit to provide more useful info, although I haven't done that yet. The disadvantage is that the Java builder is trying to compile my whiley files ... and it obviously can't. Originally, I had the Java Builder run first, then the Whiley builder. Superficially, this actually worked out quite well since all of the errors from the Java Builder were discarded by the Whiley Builder (for whiley files). However, I actually want the Whiley Builder to run first, as this is the best way for me to resolve dependencies between Java and Whiley files. Which leads me to my question: can I stop the Java builder from trying to compile certain java-like resources? Specifically, in my case, those with the "*.whiley" extension. As an alternative, I was wondering whether my Whiley Builder could somehow update the resource delta to remove those files which it has dealt with. Thoughts?

• Windows Server 2012 and Ubuntu 12.04.1 under Hyper-V

  - by Technicolour

  I've set up an instance of Ubuntu 12.04.1 LTS under Hyper-V 2012. However it seems to be nondeterministic as to whether or not it completes the boot process. I get a Kernel Panic, "IO-APIC + timer doesn't work!", which from my research is caused by not having integration services correctly installed? It was my understanding that the integration services were all now baked into the kernel? It should then be fine to update the OS (including any kernel updates, as I'm guessing that's what has happened) Being able to rely on this successfully booting would be great as I intend on using ssh for crisis situations.

• Issues running java in Solaris 9 container

  - by Matthew Watson

  Hi, I have a solaris 9 container built from a physical server using flarcreate. Everything seems fine, except when trying to trying to run any "java -server" process it fails with the following error This is on a Sunfire T1000 machine running Solaris 10 10/09 s10s_u8wos_08a SPARC Running jdk1.5.0_15 Exception java.lang.OutOfMemoryError: requested -4 bytes for size_t in /BUILD_AREA/jdk1.5.0_15/hotspot/src/os/solaris/vm/os_solaris.cpp. Out of swap space? As far as I can tell I'm not actually out of swap space. Running java in client mode works without a problem. Googles only suggestion is related to x86. Any suggestions? Thanks.

• Moving Windows 7 profile to new user

  - by Kevin Grossnicklaus

  I have a laptop which I've been using as part of a corporate network with an AD login (and associated local profile). The laptop is loaded with Windows 7 Ultimate. I need to remove the laptop from this domain and, to start this process, I have already configured a local user on the box for me to use moving forward (granting this user the same local admin rights as the AD user). I'd like to migrate all the files, settings, etc from the local AD profile to the new non-AD profile. Is there a simple way to do this? Anything built into Win 7? As far as basic files I can probably just manually copy all the documents, pictures, music, desktop, favorites, etc... But is there a more streamlined way to move profile information? -Kevin

• Can't complete dropbox installation from behind proxy

  - by Mark Jones

  Problem: My PC on campus sits behind a proxy (requiring authentication) and I can't setup Dropbox. I am convinced that this is a proxy issue as I can't setup Ubuntu one either (but I don't use Ubuntu One so that is not a problem). I have looked at the Ubuntu One fix but it seems to be to modify settings explicitly related to Ubuntu One. I can install the nautilus-dropbox package (compiled from source and from .deb package from website and from software centre) but once I click OK from the "Dropbox Installation" dialog box (prompting me to download the proprietary daemon) the installation just freezes with the OK button pressed. When I look at its process in System Monitor its waiting channel is inet_wait_for_connect. I have set the following proxy directives thus far: Added mj22:**@proxy.waikato.ac.nz:80 information to network proxy settings under network in settings. Added http_host and http_port variables under gconf-editor-system-proxy Added 'host', 'authentication_password' 'authentication_user' and ticked 'user authentication' and 'use_http_proxy' under gconf-editor-system-http_proxy Added export http_proxy="http://mj22:**@proxy.waikato.ac.nz:80/" to /etc/bash.bashrc Added Acquire::http::proxy "http://mj22:**@proxy.waikato.ac.nz:80/"; to /etc/apt/apt.conf (which is what I imagine is letting Software Center retrieve packages). (where ** is my password) I have also added the equivalent ftp and https lines for the above entries. I get the internet fine and Software Centre can download packages but thats it. Related issues: The software centre can't fetch reviews (but can download packages). When trying to add an online account in Gnome 3 a dialog pop up appears with "Error getting a Request Token: Cannot connect to proxy (proxy.waikato.ac.nz)" Updates: After some time (10mins ish) Dropbox shows an error dialog box that reads: Trouble connecting to Dropbox servers. Maybe your internet connection is down, or you need to set you http_proxy environment variable. Is there a way I can see what environment variables are currently set?

• My New Job

  - by Stuart Brierley

  Last year I started a new job with a logistics company in the North of England, where I was responsible for the management, design and development of IT Integration strategies, architectures and solutions using BizTalk Server 2009.  This included the design and implementation of the BizTalk Server 2009 infrastructure, the definition of development standards, mentoring a fellow developer in the ways of BizTalk and migrating a number of existing solutions from Softshare over to BizTalk 2009. Unfortunately I then realised that, following this initial set up, there didn't actually seem to be that much BizTalk work for me to get stuck into and reluctantly I have now moved on from this role to a very similar role with the country's largest office supplies company.  Based in Sheffield, we distribute office supplies on a UK wide basis and computer supplies across Europe. The situation here is slightly different than when I first joined my previous employer.  Whereas that was a green field installation with no previous BizTalk solutions in place, my new employer currently has a number of live BizTalk 2000 (!) and BizTalk 2006 solutions in place.  Unfortunately the infrastructure around these is less than ideal; with no clear distinction between development and test environments and no source control what so ever! We are currently building a proposal for a new BizTalk Server 2010 implementation, where I am hopeful of being able to implement fully independent development, test and pseudo-live environments, alongside an enterprise level live installation.  We should also be introducing Team Foundation Server to the development process, thereby giving us some much needed source control capabilities. Following this is likely to be a period of migration for the existing BizTalk Solutions, along with the onward development of new projects and initiatives - I'm hoping to be a busy man for the forseeable future :o)

• RUEI 12.1.0.3.0 dependency requirement for php-soap-5.1.6

  - by sthieme

  Dear Readers,please be aware of the new php-soap-5.1.6 dependency in RUEI 12.1.0.3.For a swift upgrade to RUEI 12.1.0.3 you should be aware of this pre-requisite as it can be a time-eater to obtain individual rpm-packages inside of a datacenter for an old OS revision once you have started the upgrade process. You may use the following procedure to retrieve the required package via http://public-yum.oracle.com:Customers will have to check the /etc/issue, /etc/issue.net (or /etc/redhat-release for RHEL based OS) for their current release in order to obtain the fitting package version.Customers of OEL can download the packages from our public-yum.oracle.com Server: http://public-yum.oracle.com/repo/,  e.g. http://public-yum.oracle.com/repo/OracleLinux/OL5/8/base/x86_64/php-soap-5.1.6-32.el5.x86_64.rpmEarlier releases (up to 5.5) are located under the EnterpriseLinux instead of OracleLinux path, e.g.http://public-yum.oracle.com/repo/EnterpriseLinux/EL5/5/base/x86_64/php-soap-5.1.6-27.el5.x86_64.rpmNote: you will have to obtain the relevant RedHat rpm-packages via the login protected RHN URLs. Oracle can only provide support for Oracle Enterprise Linux and RHEL packages are not available publicly via rpm-seek.com to my knowledge. Kind regards,Stefan

• postgres memory allocation tuning 2

  - by pstanton

  i've got a Ubuntu Linux system with 12Gb memory most of which (at least 10Gb) can be allocated solely to postgres. the system also has a 6 disk 15k SCSI RAID 10 setup. The process i'm trying to optimise is twofold. firstly a single threaded, single connection will do many inserts into 2-4 tables linked by foreign key. secondly many different complex queries are run against the resulting data, using group by extensively. this part especially needs to be optimised. i have four of these processes running at once in order to make use of the quad core CPU, therefore there will generally be no more than 5 concurrent connections (1 spare for admin tasks). what configuration changes to the default Postgres config would you recommend? I'm looking for the optimum values for things like work_mem, shared_buffers etc. relevant doco thanks!

• How can I retrieve the details of the file from an outbound operation in BPEL 11g

  - by [email protected]

  Several times, we come across requirements where we need to capture the details of the file that got written out as a part of a BPEL process invoking a File/Ftp Adapter. Consider a case where we're using FileNamingConvention as "PurchaseOrder_%SEQ%.txt" and we need to do some post processing based on the filename (please remember that we wouldn't know the filename until the adapter invocation completes) In order to achieve this, we need to manually tweak the WSDL so that the File/Ftp Adapter can return the metadata of the file that was written out. In general, the File/Ftp Write/Put WSDL operations are one way as shown below:         The File/Ftp Adapters are designed to return the metadata back if this WSDL is tweaked into a two-way WSDL. In addition, the <wsdl:output/> must import the fileread.xsd schema (see below). You will need to copy fileread.xsd from  here into the xsd folder of your composite.       Finally, we will need to tweak the  WSDL. (highlighted below)           Finally, the BPEL <invoke> would look as shown below. Please note that the file metadata would be returned as a part of the BPEL output variable:

• How can a non-technical person learn to write a spec for small projects?

  - by Joseph Turian

  How can a non-technical person learn to write specs for small projects? A friend of mine is trying to outsource some development on a statistics project. In particular, he does a lot of work in excel, and wants to outsource the creation of scripts to do what he now does by hand. However, my friend is extremely non-technical. He is poor at writing technical specs. When he does write a spec, it is written the way you would describe doing something in excel (go to this cell and then copy the value to that cell). It is also overly verbose, and does examples several times. I'm not sure if he properly describes corner cases. The first project he outsourced was a failure. I think he overdescribed some details, but underdescribed corner cases. That and/or the coder he hired didn't think through the corner cases and ask appropriate questions. I'm not sure. I got on IM with him and it took me half an hour to dig out a description that should have taken five minutes or less to describe. I wrote the scripts for him at the end, but didn't examine why his process with the coder failed. He has asked me for help. However, I refuse to get involved, because taking his spec and translating it into clear requirements is 10x more work than executing on a clearly written spec. What is the right way for him to learn? Are there resources he could use? Are there ways he can learn from small, low-pressure practice projects with coders? Most of his scripts are statistical and data processing oriented. e.g. take this column and run an average over it. Remove these rows under these conditions. So the challenge is different than spec'ing a web app.

• Free internet radio station server software with remote broadcasting?

  - by Zachary Brown

  I am in the process of creating an internet radio station, but the two djs I have for it are not able to be in one place. I need for them to be able to login to a web based broadcasting session that still has full functionality. They need to be able to broadcast thier live shows with talk and music. The music will be stroed on the server. I have checked out the Broadwave media streaming server from NCH, but ti does not have the ability to login as a dj from a remote computer. I don't have any money for this, so I need it to be free. If this is not possible, I need it to be cheap!

• Releasing an open source project without getting embarrassed

  - by Hopeful

  I've been working by myself on a fairly large open source project for quite a while and it's nearing the point where I'd like to release it. However, I'm self-taught and I don't really know anyone who could adequately review my project. A few years ago, I had released a small bit of code which pretty much got ripped apart (in a critical sense) on the forum where I released it. Even though the code worked, the criticism was accurate but brutal. It prompted me to begin searching for best practices for everything and in the end I feel that it made me a much better developer. I've gone over everything in my project so many times trying to make it perfect that I've lost count. I believe in my project and think it has the potential to help a lot of people and I feel like I've done some cool things in interesting ways with it. Still, because I'm self-taught, I can't help but wonder what gaps exist in my self-education. The way my code was ripped apart last time isn't something I'd like to repeat. I think my two biggest fears with releasing my project that I've poured countless hours into are being absolutely embarrassed because I missed some patently obvious things because of my self-education or, worse, releasing it to the sound of crickets. Is there anyone who has been in a similar situation? I'm not afraid of constructive criticism, so long as it is constructive and not just a rant on how I screwed up. I know there is a code review site on StackExchange, but it's not really set up for large projects and I didn't feel like the community there is large enough yet to get good feedback if I were to post parts of my project piecemeal (I tried with one file). What can I do to give my project at least some measure of success without getting embarrassed or devestated in the process?

  Have you ever accidentally deleted a photo on your camera, computer, USB drive, or anywhere else? What you might not know is that you can usually restore those pictures—even from your camera’s memory stick. Windows tries to prevent you from making a big mistake by providing the Recycle Bin, where deleted files hang around for a while—but unfortunately it doesn’t work for external USB drives, USB flash drives, memory sticks, or mapped drives. Luckily there’s another way to recover deleted files.

• Unable to run VMs on hyper-v

  - by PRAWAT-DS

  Folks/Mates, I need some advise and assistance regarding the testing of Hyper-V. Here is my h/ware configuration: 1) Intel i5 processor (i5-750) 2) Intel M/B DP55WB 3) 6 GB DDR3 RAM OS = Server 2008 R2 Standart (evaluation copy). I installed 2008 r2 on my machine and added hyper-v role to it. I created 2 VMs and installed OS. But after finishing the OS installation the VMs are not booting up. After finishing the OS installation, the VM reboots automatically (normal behaviour) and shows "preparing your system for first time" after that it reboots and didn't come online. Few things to notice, when I am running "securable" on my server 2008 R2 OS it shows that processor is not supporting h/ware virtulization, but (since my desktop is dual boot) when I am running "securable" on my windows 7 OS, it shows that process "does" supports hardware virtulization. VT option is already enabled in BIOS. Any help and suggestions are highly appreciated :) Thanks in advance. Pradeep Rawat

• Who is code wanderer?

  - by DigiMortal

  In every area of life there are people with some bad habits or misbehaviors that affect the work process. Software development is also not free of this kind of people. Today I will introduce you code wanderer. Who is code wanderer? Code wandering is more like bad habit than serious diagnose. Code wanderers tend to review and “fix” source code in files written by others. When code wanderer has some free moments he starts to open the code files he or she has never seen before and starts making little fixes to these files. Why is code wanderer dangerous? These fixes seem correct and are usually first choice to do when considering nice code. But as changes are made by coder who has no idea about the code he or she “fixes” then “fixing” usually ends up with messing up working code written by others. Often these “fixes” are not found immediately because they doesn’t introduce errors detected by compilers. So these “fixes” find easily way to production environments because there is also very good chance that “fixed” code goes through all tests without any problems. How to stop code wanderer? The first thing is to talk with person and explain him or her why those changes are dangerous. It is also good to establish rules that state clearly why, when and how can somebody change the code written by other people. If this does not work it is possible to isolate this person so he or she can post his or her changes to code repository as patches and somebody reviews those changes before applying them.

• RMS java web framework

  - by Kamil Tomšík

  We're currently reconsidering technologies and frameworks to get more agile with "simple" RMS CRUD-based projects. In short, short-living things like this Right now we have custom extension on top of SmartGWT but after some time it has proven not to be enough flexible. I also personally dislike that java-js compilation process and the whole GWT codebase. Not only its ugly designed, it also makes certain low-level js things very complicated if not completely impossible. So what I'm looking for is: closest to web as possible, like JSF or possibly Tapestry, it is very important to be able get "low" and weave framework if necessary. Happens more often than we thought. datagrid capable - Ext.js & PrimeFaces looks pretty good, Vaadin does too. db-schema generators (optional, no matter in which way) If it were only on me, I'd probably stick to Ext.js + custom rest-based java solution, possibly generated from database schema (not sure about concrete tooling yet) I only does have experience with vanilla Ext.js, vanilla GWT and JSF 2.0 / Seam, so it kinda hard for me to judge or even propose other frameworks. What would be your proposition? What are the problems you've faced, what was your solution and how hard do you think it was to deal with them in "big picture"?
