This is probably something to do with ATOM and xml namespaces that I just don't understand yet.
I have gotten it to work by removing all attributes from the **feed** tag, but that's a hack and I would like to do it properly. So, how do you use **SelectNodes** with atom feeds?
Here's a snippet of the feed.

Basically, I was looking for a way to do constant updates to a web page from a long process. I thought AJAX was the way to go, but Dave has [a nice article about using Javascript][3]. I integrated it into my application and it worked great on my client, but NOT my server WebHost4Life. I have another server @ Brinkster and decided to try it there and it DOES work. All the code is the same on my client, WebHost4Life, and Brinkster, so there's obviously something going on with WebHost4Life.
I'm planning to write an email to them or request technical support, but I'd like to be proactive and try to figure out what could be going on with their end to cause this difference. I did everything I could with my code to turn off Buffering like Page.Response.BufferOutput = False. What server settings could they have implemented to cause this difference? Is there any way I could circumvent it on my own without their help? If not, what would they need to do?
For reference, a link to the working version of a simpler version of my application is located @ [http://www.jasoncomedy.com/javascriptfun/javascriptfun.aspx][4] and the same version that isn't working is located @ [http://www.tabroom.org/Ajaxfun/Default.aspx][5]. You'll notice in the working version, you get updates with each step, but in the one that doesn't, it sits there for a long time until everything is done and then does all the updates to the client at once ... and that makes me sad :(

I want to create a custom Activity class for Windows Workflow. The activity has to call out to a third party library method that itself runs another process asynchronously and may take anywhere from seconds to many hours to complete. This library offers the ability for me to either poll for the method result or to subscribe to an event that indicates its completion. In my non-workflow apps, I typically just subscribe to that event, but that doesn't seem to be reasonable in the workflow case. I'm also not sure exactly how to best implement a polling scheme. Can someone recommend some pointers to similar problems?

Will model checking ever become a more "mainstream" developing practice that we should have in our toolkit?

* Datamation SWIFT Message Suite ([link text][2])
Both libraries allow to accomplish the tasks mentioned above but in both cases I'm not really happy.
AnaSys uses a internal XML representation for all SWIFT messages which you need to know in order to access the fields of a message. And you need to operate on the DOM of the XML representation, there is no way to say "get the contents of field '50K' of the SWIFT message".
And the Datamation library seems to have the nicer API but does not find all errors.
So does anyone know other SWIFT libraries to use?

I know lots of people are against them. I'm quite fond of brainteasers (math/CS-based, and I certainly prefer those which don't require any specialized knowledge).
In my line of work, 'problem solving' is quite an important requirement when looking for new hires and I think brainteasers *can* be a good tool. However, there are a few problems with them:
- it's hard to find an original brainteaser (there's no point reusing over and over again the same brainteasers, as candidates will just get the 'list');
- it's hard to find a brainteaser which is quite 'open', from which a conversation can start with a candidate (I really dislike those which have a 'trick', and much prefer those which have different solutions, extensions,...);
- using one (or more) brainteasers in an interview process tends to take (a lot of) time;
- some people are so much stressed during a job interview that they sometimes even lack the self-confidence needed to just 'have a go'.
As an interviewee, I have to say that being given brainteasers that I found interesting during the interview process is one of the reasons I chose my current employer!
So, what are your thoughts/advice on the use of brainteasers?

I want all my scrollbars save and restore their position whenever an ajax-call occurs.
I tried different approaches, but none seems really good to me, so I need some hints which way to go:
1. JavaScript:
Add a JavaScript which reads all scrollbar-positions either when a scroll occurs (element.onScroll must be set by javascript, cause this attribute is not available in XHTML4) or when an ajax-request occurs (jsf.ajax.addOnEvent(savePositions)).
Save the scrollbars' positions either in hidden input-fields or in cookie.
Restore them when the ajax-response occurs (jsf.ajax.addOnEvent(restorePositions)).
Contras if not using cookies:
-The scroll position must be stored in the hidden input field before the ajax-request occurs, so the element.onScroll-attribute must be used here. Not really nice, cause it saves the positions many many times, although one time before each ajax-request would be sufficient.
-All hidden input fields must be transferred in the ajax-call. Since the JSF-site uses several forms, there seems no way to automatically add them to all ajax-calls. Instead every <f:ajax> element needs the hidden input fields added to the execute-attribute.
-One hidden input field is needed for every scrollable element.
Contra if using cookies:
-well, cookies need to be enabled for the website.
Contra in general:
-JavaScript code must either know or iterate through all elements, which have scrollbars.
-JavaScript code must be executed again, if a componenent is re-rendered and needs the onScroll-attribute set.
2. JavaScript + Composite:
So I thought of writing a composite scrollStateSave, which points to the JSF-id of the element, which has the scrollbars. The composite contains the hidden input field (or cookie) and javascript and handles everything, so I just need to add one "instance" of the composite per element, which has scrollbars. The javascript makes use of closures to work for multiple elements on one site.
Contra:
-The javascript inside the composite is not executed on a re-render after an ajax-call. There are workarounds for this, but they look ugly to me.
3. Myfaces has an option AUTO_SCROLL: How does it work exactly? Does it work for non-myfaces-jsf-components?
4. Tomahawk offers a <t:autoScroll>-behaviour. Using the tomahawk-replacements for the standard-mojarra-jsf2-components would be ok for me. but documentation of <t:autoscroll> speaks of an attribute "event", while implementation needs attribute "value". What should I put in this attribute to make <t:autoScrolll> work? | jsf-2.0 | null | null | null | null | null | open | JSF2+AJAX: Keep Scrollbar position, plain mojarra
===
I have a more complex webapp in JSF2 (+EJB3.1 +JPA2 on glassfish 3.1), which only uses standard (mojarra) JSF-components and makes massive use of nested composites and ajax-calls.
I want all my scrollbars save and restore their position whenever an ajax-call occurs.
I tried different approaches, but none seems really good to me, so I need some hints which way to go:
1. JavaScript:
Add a JavaScript which reads all scrollbar-positions either when a scroll occurs (element.onScroll must be set by javascript, cause this attribute is not available in XHTML4) or when an ajax-request occurs (jsf.ajax.addOnEvent(savePositions)).
Save the scrollbars' positions either in hidden input-fields or in cookie.
Restore them when the ajax-response occurs (jsf.ajax.addOnEvent(restorePositions)).
Contras if not using cookies:
-The scroll position must be stored in the hidden input field before the ajax-request occurs, so the element.onScroll-attribute must be used here. Not really nice, cause it saves the positions many many times, although one time before each ajax-request would be sufficient.
-All hidden input fields must be transferred in the ajax-call. Since the JSF-site uses several forms, there seems no way to automatically add them to all ajax-calls. Instead every <f:ajax> element needs the hidden input fields added to the execute-attribute.
-One hidden input field is needed for every scrollable element.
Contra if using cookies:
-well, cookies need to be enabled for the website.
Contra in general:
-JavaScript code must either know or iterate through all elements, which have scrollbars.
-JavaScript code must be executed again, if a componenent is re-rendered and needs the onScroll-attribute set.

So I thought of writing a composite scrollStateSave, which points to the JSF-id of the element, which has the scrollbars.

Why would access to the database work from website one, and not website two..?
Does anyone know how to make windows auth work the same as the anonymous setting so I have access to the database from website two..?

I have an AJAX application where there are 4 routes that all return JSON to be used by jQuery.
I'm currently using something like this at the end of the Controller
return new Response(json_encode($some_array));
In one place I use JMSSerializer because the object I'm trying to pass out to Javascript has protected attributes. That never seemed right and I wondered at one point if I should 'teach' the object to know how to encode all its attributes to JSON and send them out as the return value of one of its methods.
Anyway I had a brainwave this morning that what I **should** be doing is to make a Twig JSON template that contains the exact format I want it to output, then fill the variables from the PHP. A couple of loops would also be necessary to output a collection of objects within an object.
That way there's a clear promise/contract from the PHP of what exactly it will return to the Javascript, that can't be messed up if I happen to e.g. change the object. I suspect this would be easier for the guy who's doing the javascript to understand since the template would be easier to read than the PHP.

Typical scenario. We use old-school XML Web Services *internally* for communicating between a server farm and several distributed *and* local clients. No third parties involved, only our own applications used by ourselves and our customers.
We're currently pondering moving from XML WS to a WCF/object-based model and have been experimenting with various approaches. One of them involves transferring the domain objects/aggregates directly over the wire, possibly invoking DataContract attributes on them.
By using IExtensibleDataObject and a DataContract using the Order property on the DataMembers, we should be able to cope with simple property versioning issues (remember, we controll all clients and can easily force-update them).
Yet I keep hearing that we should use dedicated, transfer-only Data Transfer Objects (DTOs) over the wire.
Why? Is there really still a reason to do so? We use the same domain model on the server side and client side, of course prefilling collections etc. only when deemed right and "neccessary". Collection properties generally utilize the service locator principle and IoC to invoke either an Nhibernate-based "service" to fetch data directly (on the server side), and a WCF "service" client on the client side to talk to the WCF server farm.

I didn't find any information about building flash projects in a way that lets the coder do their thing AND gives the designer freedom as well.
Hopefully more experienced people can share, these are some of the things i discovered after a few projects
- Version control is a must (as always) but can be difficult to explain to designers
- No actionscript in the flash .fla files, they are binary and as a coder you want to try to keep away as much as possible
- Model View Controller is the best way i've found to isolate visual design changes

Many frameworks seek to abstract away from HTML (custom tags, JSFs component system) in an effort to make dealing with that particular kettle of fish easier.

I've even tried "pop-out" time selection menus (which allow you to, for example, hover over the hour "10" to receive a submenu that contains ":00",":15",":30", and ":45") -- but none of these methods seem natural.
So far, the best (and most universal) method I have found is just using simple text fields and forcing a user to manually populate the hour, minute, and second. Alternatively, I've had good experiences creating something similar to Outlook's "Day View" which allows you to drag and drop an event to set the start and end times.
Is there a "best way" to ask for this information? Is anybody using some type of time input widget that's really intuitive and easy to use? Or is there at least a way that's more efficient than using plain text boxes? | time | input-devices | null | null | null | null | open | Best Practices: What is the most efficient way to populate a time (or time range)?

While plenty of solutions exist for entering dates (such as calendars, drop-down menus, etc.), it doesn't seem like there are too many "standard" ways to ask for a time (or time range).

Has anyone been able to successfully extract information such as the current disk space used, CPU utilisation and memory used in the underlying OS? What about just what the Java app itself is consuming?
Preferrably I'd like to get this information without using JNI. | java | null | null | null | null | null | open | Using Java to get OS-level system information

H3Y5NC8E-TGA5B6SB-2NVAQ4E0
and return the following using Split:
H3Y5NC8E
TGA5B6SB
2NVAQ4E0
The number of characters in each group can vary and the number of groups can also vary. I am using the following expression:
([ABCDEFGHJKLMNPQRSTVXYZ0123456789]{8}-?){4}
This works insofar as it correctly matches the input. However, when I use the Split method to extract each character group, I just get the final group. RegexBuddy complains that I have repeated the capturing group itself and that I should put a capture group around the repeated group. However, none of my attempts to do this achieve the desired result. I have been trying expressions like this:
(([ABCDEFGHJKLMNPQRSTVXYZ0123456789]{8})-?){4}
But this does not work.
Since I generate the regex in code, I could just expand it out by the number of groups, but I was hoping for a more elegant solution.
