I'm trying to find options for MQ on the iSeries besides WebSphere MQ. Does anyone have experience with this? Is it possible? Could I run a pure java MQ server like OpenMQ?
I don't see any reason why not, though I haven't personally tried. However, I would strongly recommend going with a software package that supports AMQP. I believe it's planned for OpenMQ, but isn't actually implemented yet. Apache Qpid is probably something you should look at. It's almost as good as RabbitMQ, but written in Java and JMS compliant.

I'm looking for a build tool (such as ant, maven, make, etc.) that uses JSON-based configuration files?
Does such a tool exist?
Nokia/Qt just announced their "QBS" build system, which is JSON-based, and is actually a build engine intended for easy adoption by IDEs (a principal reason for adopting JSON).
Introducing qbs
Rather than a "pre-make" generator of Makefiles/vcprojs/etc. (like CMake and QMake, etc.), qbs is intended to actually be the build engine.
Google turned up Gaudi though it is still in the early phases.
I think what you're really looking for is a build tool that doesn't force you to configure everything in XML?
In that case your best bet is Gradle. It doesn't have the same sort of adoption as ANT or Maven, but does have the advantage of learning lessons from both.
I would advise you to beware of straying from standard build tooling... It makes life tougher for others attempting to build your code. This is something Gradle solved by providing a build wrapper.
I am looking to start a HTML5 WebSockets project and I was just wondering what you think the best back-end would be for that sort of thing? So far in my research I've stumbled across the following:
PHP Back-end (apparently a "Hack" and only compatible with Chrome and webkit nightlies)
Java Back-end (Seems well documented and cross-browser compatible)
Ruby Back-end (Don't know much about ruby, any opinions?)
JavaScript Library (Seems like it would be a nightmare, any opinions?)
Does anyone know of any other options or have an opinion on the above? My only requirements are ease of set-up and easy back end programmibility for bidirectional communication. I would essentially like to access a database through WebSockets and am looking for the easiest way to do this. Any feedback would be appreciated.
Ease of setup would have to be a hosted solution which uses WebSockets, HTTP Streaming or HTTP Long-Polling (one of which I work for). They're the easiest option because you don't need to spend time installing your solution, configuring it and working out how to use in when developing and in production.
If you are looking for a self hosted solution then it really depends on what technology you'd prefer to use and what the community for that technology is like.
Node.js and socket.io has a big community following at the moment so it wouldn't be a bad choice.
PHP - I'm afraid that PHP isn't really build with long-held persistent connections in mind. So, although there are options it's probably best to either use a hosted service or steer clear.
Ruby - check out Faye (also has node.js option), Juggernaut or Cramp
Java: As you say, jwebsocket or WaterSpout Server
Hope this helps.
I 'd recommend websocketd
http://websocketd.com/
It 's a thin layer you can wrap around any program that reads from stdin and writes to stdout and transform it to a websocket server.
So you can write in any language you like. Afterwards just
$ websocketd --port=8080 my-program
and you have your server.
I want to know if it's possible to make my own chat application with ajax push.
And if it's, what is the easiest way to do it?
I know how to use javascript and make ajax calls but that's as far as I go. I can find tutorials myself but I can't tell whether the method is good or not so any links will be appreciated.
Thanks
to use ajax push (comet), you must make a server that will keep concurrent connections.
You can really do anything look for echo servers in your favorite language. Java/C/C++.. I'd do this in Java since it can run on Linux as well.
You can use http://www.ape-project.org/ which seems to be done already all for you.. but seems complex.. I'd recommend starting from scratch with a echo server.
I would recommend using Node.js as it is great at Comet/Ajax-push. Why is it great? Comet applications tend to be event driven and Node.js/javascript excels at these kinds of things.
However, if you prefer to do it in Java, Tomcat actually supports Comet as long as your servlet implements CometProcessor and you use NIO as your http connector. See http://tomcat.apache.org/tomcat-6.0-doc/aio.html
Our group uses Visual Sourcesafe as a file repository for all of our "content" (HTML, CSS, Javascript, JSP). None of it requires building or compilation but we would like to automate the copying of it to a Unix dev server upon check-in.
I have used Cruisecontrol.NET in the past for CI at other companies but it was for .NET. What would be the easiest way to achieve our current requirements? Would using CruiseControl.NET be overkill or even a good idea? Thanks in advance.

This sounds like overkill for a CI tool.
Visual SourceSafe and other version control systems should have hooks allowing you to automate a simple file copy operation.
From http://msdn.microsoft.com/en-us/library/aa302175.aspx
Use events, such as OnBeforeCheckout
or OnAfterCheckIn to automate your
process.
Whether this makes sense for you depends on a couple of factors. If you are talking about a large, geographically team with only change based deployment then yes, those are valid concerns. If you only have a few local developers and you deploy the world on each copy operation, then no, I don't think you'd need a CI tool.
This is not to say other reasons may influence you to use a CI tool, testing for instance. Your problem might also be solved by running a polling script on the Unix box to sync the source control with the dev server. I guess the main point is, if you are deploying all non-compiled software, why do you have a separate source control and dev server? You're deployment can be done by a source control tool. If it is only for backup, there are plenty of existing solutions for that problem.
Sean,
Our AnthillPro customers do this kind of thing pretty frequently (and we even do it internally when new content is committed for our website). It's a really good idea, totally appropriate for a CI tool, and you can get quality feedback if you wire in some automated functional / regression tests.

You could try using Hudson http://hudson-ci.org/
It is easy to configure, is completely GUI (unless you want to go into the details), and has a plugin for Visual Sourcecafe http://wiki.hudson-ci.org/display/HUDSON/Visual+SourceSafe+Plugin
While CI would probably be overkill for what you are trying to do, since Hudson is all GUI and easy to use, you would not spend a lot of time just trying to configure it.
Hudson also has plugins for copying stuff over to other systems, and so it would be easy to deploy your content to another system.
If you are worried about the process, get in touch with a hosted CI provider, such as MikeCI, a quick message on their support board will get you the answer. I don't see why triggering a "build" can't be replaced with copy and paste!
Is there any API or tool that can automate software updating? It should take care of checking for updates from a URL for a provided list of files and downloading and replacing the ones that need updating. It would also be nice if it contained an authentication module so that only authorized parties could access the updates. It should be language-agnostic - takes a list of files without extra knowledge except their versions and replaces them with newly downloaded copies if on the site there are newer versions.
I'm specifically interested in something for the Windows platform, that would run on Win Xp to Win 7.
This makes me think about apt-get ...
take a look here, as well: Is there an auto-update framework for C++/Win32/MFC (like Sparkle)?
I did see some articles a while back about embedding subversion into your application to manage version control.
Edit:
http://svnbook.red-bean.com/en/1.5/svn.developer.html
Subversion has a modular design: it's implemented as a collection of libraries written in C. Each library has a well-defined purpose and application programming interface (API), and that interface is available not only for Subversion itself to use, but for any software that wishes to embed or otherwise programmatically control Subversion. Additionally, Subversion's API is available not only to other C programs, but also to programs written in higher-level languages such as Python, Perl, Java, and Ruby."
Just saw UpdateNode launching a pretty cool update and messaging system. It seems to be cross platform and free for Open Source.
UPDATE, did some further analysis on that, posted at: https://stackoverflow.com/a/22528011/3257300
For windows, I'd use Google Update, also known as omaha.
Since you didn't tag this question as windows, I'd also mention a UpdateEngine for Mac.
And (best of all) apt, which is available for free on all Debian-based Linux and BSD distributions, like Ubuntu
There is open source project WIPT inspired by APT of Debian Linux.
Head over to Launchpad and use a PPA: it is a Debian/Ubuntu repository management platform. Of course this is not really platform independent but it is language wise :-)
You should take a look at ClickThrough, I don't know much about it but it sounds similar to what you're looking for. As for authorization, I would imagine this to be handled by your webserver based on the URL.
InstallShield has an offering. Never used it but researched it a few years back but we decided on a roll your own solution.
InstallShield Update Manager
InstallShield Update Service
You didn't state what platform you needed this for. The easiest way I can think of doing this is with subversion using rsync.
The concept is to write a post-commit hook for subversion. This script would update a "working folder" on the repository machine and then use rsync to update the differences to another machine.
Data protection and authentication would be set up using rsync over ssh.
If this is for windows, you could try doing the same with cygwin installs on the two machines.
Good luck.
If you use .NET, I'm a happy customer of AppLife Update
CRONw is a scheduled execution service for Windows. (Sorry, I can't link it, I'm apparently limited to 1 as a new user. It's hosted on Sourceforge.)
Powershell is a Windows scripting language (Microsoft-official) that allows you to do most system administration operations you could conceivably want to do. It is very easy to pick up even if you haven't worked with it before.
I would say your best bet is to write a simple update script in Powershell and, optionally, set it up as a crontask so you don't have to manually execute it.
IIRC, Powershell is an optional install on XP, and CRONw requires you be running a 32-bit system. You didn't say, so I'd guess you're doing 32-bit, but the alternative bears mentioning.
And in all this, I'm assuming that the URLs you're describing are designed for this purpose - if they're not and you don't own them, it will rapidly become more suffering than you're willing to bear. (Making a computer navigate a human-readable website usually does.)
