Tracking Stats

Hi All, new to podcasting here...
Is there a way to determine how many people are subscribed to my podcast through iTunes? Or is this determined with tools with the host. I'm using Podbean, and they have subscriber stats but it's not available to free users...
Thanks in advance!
Mike

I would recommend Podtrac, it is far superior to FeedBurner. Clearer statistics, more detailed information, etc. We've been using it for the Freeskier Magazine Podcast for over six months now.

Track "state" in Captivate 2.0

Hello Captivate Forum Members,
First - thanks for the help and good information that this
forum provides!
My question of the day is: Can I track state in captivate?
I am using Captivate 2.0.
What I mean is: I have a slide setup with 5 buttons. Each
button click takes the user to a particular slide in the
presentation. If the user clicks a button on a given slide
that "returns to the main menu" slide, is there a way to
gray-out the first button, the user has clicked? The idea
here is so the use can see which part of the tutorial
has been viewed.
Scenario - the user clicks a button, watches a presentation,
returns to main slide, click a different button, watches a
different presentation, returns to main slide, and now two buttons
are grayed out, showing which subject has been viewed so far.
thanks for any tips. I was thinking that some sort of
Javascript could be used to do this???
Thanks Again for a helpful forum,
eholz1

It's been awhile since I looked at it, but Jesse Warden's
Captivate Player might offer what you're looking for. If you're OK
with using a menu instead of buttons and breaking your sections out
into individual movies, then give it a look.
Links to a Captivate Developer Center article, documentation
and the latest version can be found at
Jesse's
website.
If you decide to use the player, be sure to grab the
documentation separately as I don't think it is included with the
latest build.

Track State in Project

Hello All,
Happy New Year! I need to "track the state" of lessons in our
tutorials. What I mean by this is: I have an on-line tutorial (a
demo), it has 5 parts (lessons). I want to be able to tell/show the
user which lesson they are on, and which lesson has concluded or is
concluding. I know that captivate (3.0 here) will not track state
like a web page. I was thinking i could make a skin without
buttons, etc. but with text that says " Lesson 1 ", and then put my
app skin with-in that skin, much like your suggestion in other
topic (have a skin within a skin)
[You can view the message at
http://www.adobe.com/cfusion/webforums/forum/messageview.cfm?catid=464&threadid=1324241&fo rumid=67.
, with one skin with no borders, etc. What do you all think?
I know this could be done easily in Flash. It is too bad that
Captivate does not comfortably import into Flash (or vice versa).
Any ideas on how to do this? I know I could put a caption or button
on each slide that says "Lesson 1" etc. I am looking for nicer
ideas,
Thanks,
eholz1

It occurred to me that there's an easier way to show slide
count.
Captivate community contributor Paul Dewhurst offers a whole
slew of widgets for Captivate at his website. He recently created
one that shows the slide information in a custom playbar, so you
might want to check it out.
It's available at Paul's site here:

Is there a way to track # of podcast subscribers in itunes?

I don't think there is, but is there a way to see how many people have subscribed tpo a podcast in iTunes? I was listening to a podcast the other day, and they announced how many subscribers they had. Is this possible?

If you have a feed through feedburner.com, then it will track stats of subscribers. It even breaks down which of those subscribers is using iTunes, Safari, or other RSS and podcatching software.
I even have a chicklet posted on my blog that shows me the hits from the previous day from http://feeds.feedburner.com/marioajero

Trying to close Statement from its Connection object

Hi, I am having difficulty finding information regarding how to find and kill a Statement for a given Connection. Unfortunately I do not have direct access to the Statement as the Connection object has been handed off and used externally.
What I am doing is playing around with a connection pool and the effort to replace it with another at this point is not feasible, so basically what I am attempting to do is forcefully release a Connection after a specified timeout period but am finding that the Statement that it is running still persists. Waht I need to know is how I would be able to track down the Statement and .close() it as there does not seem to be any obvious way using the Connection object alone. Any ideas?
Any help or suggestion about how to address this issue would be appreciated.

Wrap the connection before handing it off to external code. Your wrapper will be responsible for tracking statement instances.

Easy Way To Track Statistics in iWeb '08?

I'm just wondering who has the easiest way to track stats of an iWeb '08 page. Any help you may have to offer would be greatly appreciated... Thanks!

Analytics and other solutions require that you change the html code after you published your webpage either to a folder or .Mac. That sounds more complicated than it is.
You could use for example this [Automator extension|http://www.apple.com/downloads/macosx/automator/addgoogleanalyticsact ion.html] to add your Analytics code to your webpage. If you update your website on a regular basis, it will ease your workflow.

Iptables: differences using conntrack or state module

I'm still new to (Arch) Linux, and I am looking into iptables right now. I was looking at the wiki, where there is this rule:
-A INPUT -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT
And I see in the default file /etc/iptables/simple_firewall.rules (owned by iptables 1.4.12.1-2) a similar rule:
-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
Now, looking in the man page for iptables, I'm not sure I see/understand the difference between those two modules, conntrack & state:
conntrack: This module, when combined with connection tracking, allows access to the connection tracking state for this packet/connection.
NEW meaning that the packet has started a new connection, or otherwise associated with a connection which has not seen packets in both directions, and
ESTABLISHED meaning that the packet is associated with a connection which has seen packets in both directions,
RELATED meaning that the packet is starting a new connection, but is associated with an existing connection, such as an FTP data transfer, or an ICMP error.
state: This module, when combined with connection tracking, allows access to the connection tracking state for this packet.
NEW meaning that the packet has started a new connection, or otherwise associated with a connection which has not seen packets in both directions, and
ESTABLISHED meaning that the packet is associated with a connection which has seen packets in both directions,
RELATED meaning that the packet is starting a new connection, but is associated with an existing connection, such as an FTP data transfer, or an ICMP error.
Descriptions of the states are exactly the same, and for the modules conntrack has a "packet/connection" where state only has "packet", but I'm not sure what the differences/implications are.
Right now, it seems to me that, in the example rule quoted above, both modules/rules would get the exact same result (the difference between the 2 modules being that conntrack allows a lot more than just using state, whereas module state obviously only uses state) -- would that be correct?
Assuming this is right, I should be safe "translating" the rules from the wiki to use the state module instead? (just because it seems module state is all I need, plus I use a custom kernet and conntrack requires a few more options to be enabled)
Also, in that case, would there be a reason why conntrack was used on the wiki? Or would it be maybe a good idea to use the state module instead? (AFAICS all rules always only uses --ctstate to filter by state, nothing else, so using module state should be enough/work the same)
Thanks for any help/information.

Hello,
I am also facing the same error: somewhere just now I read,
We were getting this error on JBoss / Oracle. The fix was setting the following to 0 in oracle-ds.xml:
<prepared-statement-cache-size>0</prepared-statement-cache-size>
Ref: http://www.jpox.org/servlet/forum/viewthread?thread=1108
May be you can try this, I am also still finding the solution, I will try the above and let u know, if i get success.

Tracking podcast usage

Hi,
The Web site I am working for requires to know usage statistics for each of their services. We are interested in producing podcasts and promoting them through iTunes, but I cannot find anywhere that tells me how to track usage statistics through iTunes. The little I found was on Apple's Web site and I pasted that below.
Does anyone know any hacks or scripts to track usage statistics through iTunes? i.e. how many people are downloading, how often, etc.
We are producing daily podcasts and plan to have an RSS feed in iTunes so the podcasts are automatically updated.
If anyone has any experience or can point me to somewhere I can read about, it would be a big help.
Thanks!
"Tracking Usage
Please note that iTunes does not provide usage statistics, because we do not host feeds or episodes. Some podcasters have created mechanisms for tracking the number of times that each episode has been downloaded. iTunes does not provide support in how to track downloads, but the following notes may be helpful:
* 302s will be followed to a depth of 5 redirects and will not update the feed URL in the directory.
* The URL before the GET-style form values (before the first ?) must end in a media file extension (e.g. mp3). To work around this, the feed provider can alter their URL from this:
http://www.podcaster.com/load.php?f=&Wipeout.php
to this:
http://www.podcaster.com/load.mp3?f=&Wipeout.mp3
Notice how it says load.mp3 instead of load.php. It should be possible to accomplish this via various means, such as web server rewrites. iTunes looks at the extension of the path part of the url, i.e. the part before the"?"."
Windows 2000

You might want to try a service like www.feedburner.com. I like it a lot for two main reasons. The first is it gives me a feed to share which is very easy to rememeber (feeds.feedburner.com/bookhobbycom). The second is that they give you free statistics which are updated daily. In fact, they show how long and when the last 25 live hits happened as well. Feedburner will also allow you to track stats on yur websiet with the addition of a small html coding. Good luck!

* The RectShape class defines a simple rectangular shape object.
* It tracks its bounding box, selected state, and the canvas it is being
* drawn in. It has some basic methods to select, move, and resize the
* rectangle. It has methods that draw the shape in the selected or unselected
* states and updates the canvas whenever the state or bounds of the rectangle
* change. The code that is there works properly, but you will need to extend
* and change the code to support additional features.

Creating a link on exported exe files

I have 9 separate projects I need to burn to a CD. I have
created an html menu. I am exporting each of the 9 projects as
stand alone exe files, each one automatically opening the next one.
But at any given time I would like the viewer to be able to exit to
the main menu. Should I just put a button linking to the main menu
on every single screen of a single project, to allow the user to
exit to the menu if they want?
FYI, I had initially created the 9 projects as html files,
linking to one another. I posted a message about that earlier. But
I am running into browser issues and don't want to run that risk
with the completed CD. Help! :)

Hello Captiv8r and others,
This thread is pretty interesting. I have been struggling
with creating a project using Captivate 3 that will
reside fully on a CD. I am looking at maybe three workflows
for this, one using exe files, one using swf files and an html page
which serves as a "menu page" (the Captivate Menu builder just does
not have enough options, in terms
of graphic display, buttons, etc.), and the last one (which
is the hardest), using some sort of Flash container, a Flash
loader, and some menu buttons built in Flash, that call up
Captivate created swf files, etc. So far we have not had to track
state. I am trying to develop a training course on MS Excel, and am
using audio and Captivate for screen shots, mouse movements, etc.
After all the BS above, I do have a question. Is there a
reason to publish to an exe file in Captivate? Or what is the
reason(s) to publish a Captivate project to an exe file in the
first place. I have searched around for the answer on this, but
have found no good answer on this. Perhaps those of you more "sage"
Captivate users can provide some insight.
Thanks again for a very helpful forum,

Since upgrading to 10.5.7, network "fades" out

My trusty old G5 still works great for the tasks I require of it and has faithfully responded to every system upgrade until 10.5.7. When I first boot it up, my account is set to launch Camino (my "second" browser) with a special URL that tracks stats on one of my websites in real time, then the system launches Microsoft Word 2008 and SuperDuper. If I don't do anything right away SuperDuper will do an automatic backup of my data drive.
During the first five or ten minutes after startup or log in, I can see my local network, the Internet and print to my printer without any problems. After a short period, I can no longer print or see my local network, though I CAN reach the Internet without any problem.
The G5 uses wired ethernet to a Verizon Westell DSL modem (an older model, one of the worst, but it usually works fine for me). I also have other wired and wireless Macs and PCs on the local network. None of them, including both newer and older Macs with 10.5.7, have this problem.
I can log out and log back in and the local network works again for a short period. I have disabled the apps that launch at startup and they do not appear to be causing the problem.
Why do I lose only the local network and not the Internet?
Any suggestions how I can determine what else may be causing this erratic behavior?

@ satcomer & shivsetlur
Thanks for the tip on Console - though I've been aware of it for years I've never actually used it for troubleshooting.
As sometimes happens in life, when you focus on a problem suddenly the problem goes away of its own accord without any obvious action. Yesterday the local network problem continued, as it has for months since the 10.5.7 upgrade. This morning, after reading your two posts, which arrived as emails, I immediately tried my network. The computer had started up on its own as it does every morning, and after I sat down in front of it two hours after that boot, the local network worked normally. Usually I would have to reboot to see the local network, or if I saw the local network in my Sidebar, clicking on any device there would result in the name disappearing or nothing happening at all.
This morning everything worked and now, several hours later, still works.
It's a l m o s t as frustrating as the original problem. I haven't added or changed anything since my original post here.
I will update this post should the problem re-occur or, after a week or two, everything is still working.
In the meantime I will try to stop scratching my head in order to prevent injury.

New error with upgrade jboss/tomcat: "Connection handle has been closed and is unusable"

Hi,
This error suddenly appeared when we upgraded from jboss3/tomcat5.0 to jboss4.2/tomcat5.5.
here's the usecase:
1) User clicks on report link
2) Crystal reports web componnent displays screen to fill in report parameters.
3) user enters parameters and clicks submit
4) System throws Exception
The same reports worked fine with jboss 3.2.6/tomcat 5.0. We haven't touched anything in this realm.
Log Excerpt:
09:42:18,842 INFO [datasource] Openning rowset
09:42:18,904 ERROR [reportdefinition] com.crystaldecisions.reports.queryengine.driverImpl.m: JDBC Error: Connection handle has been closed and is unusable

com.crystaldecisions.reports.reportdefinition.datainterface.g: JDBC Error: Connection handle has been closed and is unusable
 at com.crystaldecisions.reports.reportdefinition.datainterface.d.a(Unknown Source)
To try to narrow down the problem, I've updated the jdbc configuration to
 <track-statements>true</track-statements>
here's a recap:
This Boolean element specifies whether to check for unclosed statements when a connection is returned to the pool. If it is true, a warning message is issued for each unclosed statement. If the log4j category org.jboss.resource.adapter.jdbc.WrappedConnection has trace level enabled, a stack trace of the connection close call is logged as well. This is a debug feature that can be turned off in production.
Interestingly enough, this error appears slightly upstream:

OK. I found the problem along with a workaround.


The problem:


a programming practice clashes with a new jboss 'safety check'.


Programming practice:


crystal reports gets a database connection in one jsp page, then tries to use it on another jsp/servlet


Jboss safety check:
Jboss/tomcat new comes configured out-of-the-box with a 'cached connection
manager', which


"Check[s] for unclosed connections and transaction terminated checks in servlets/jsps."


 Summary


In short, if a servlet/jsp ends and it leaves a database connection open, Jboss will automatically close it.




Workaround: 
Comment out two entries in these two files:


1) conf/jboss4/pe/deploy/jboss-web.deployer/server.xml


2) conf/jboss4/pe/deploy/jboss-web.deployer/META-INF/jboss-service.xml


The two entries:




1)


 <Valve className="org.jboss.web.tomcat.service.jca.CachedConnectionValve" 
 cachedConnectionManagerObjectName="jboss.jca:service=CachedConnectionManager" 
 transactionManagerObjectName="jboss:service=TransactionManager" /> 


2)


 <depends>jboss.jca:service=CachedConnectionManager</depends> 




Comments on the workaround


The 'cached connection manager' basically makes sure that the application cleans up after bad programmers. It seems most helpful in development, load testing, or trouble shooting.


In production, you can likely comment them out with minimal
impact on the application.
