Sharepoint + ANTS

We use sharepoint to drive http://www.starz.com

Lately, with increased traffic, we've been seeing many issues with our app pools growing into the 6GB range! This needs serious attention, and we have to run a memory profiler against our production farm to figure out what's going on. Needless to say, doing a memory profile using the standard .net tools is pretty hard and requires an extensive amount of knowledge and time.

Along comes ANTS - and this great post:

So now the real question is how much better is the site going to be - the analysis will give us the clues. Wish me luck!

Flash h.264 HD video encoding

Flash h.264 HD video encoding is pretty hard at the enterprise level, especially when the technology keeps changing so rapidly!

Trying to use an SPWeb object that has been closed or disposed and is no longer valid.

Dealing with sharepoint is always a pain. Especially when you get a stack trace that leads you into the terrible black box of code that is completely foreign.

I kept getting this error: "Trying to use an SPWeb object that has been closed or disposed and is no longer valid."

Stack trace: at Microsoft.SharePoint.WebPartPages.SPWebPartManager.get_Web()
at Microsoft.SharePoint.WebPartPages.SPWebPartManager.ActivateConnections()
at System.Web.UI.WebControls.WebParts.WebPartManager.OnPageLoadComplete(Object sender, EventArgs e)
at System.EventHandler.Invoke(Object sender, EventArgs e)
at System.Web.UI.Page.OnLoadComplete(EventArgs e)
at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

The scenario was a simple list with a checkbox that was causing the page to reload. For some reason, sometimes it worked, and sometimes it was throwing this error.

After reading this great post, I figured out what the issue was. The using() directive was causing the SPWeb object to be disposed before all code was executed:

I commented out the shit I no longer needed, and here's an example of the result:

protected void LoadClip(yadda)
{
... do some logic ...

// using (SPWeb ThisWeb = SPContext.Current.Web)
//{
SPWeb ThisWeb = SPContext.Current.Web;
ThisTable = ThisWeb.GetSiteData(q);
//}

... and more code here with reference to ThisWeb ...

}

css display

Typically I just design and go... but dammit sometimes you have to do things for specific browsers. Whenever I run into an issue with the "display" property and it's browser-specific, I go to this page. It tells you all the compatibility differences between browsers and this wonkey css style.

android adb missing flash_image

I was updating one of our android dev phones today and found i couldn't flash a recovery ROM because i was constantly getting the error "flash_image not found"

and here's the fix! http://wiki.cyanogenmod.com/index.php/RE-recovery-img

android + Cisco VPN

We have a normal Cisco VPN at my work. After upgrading my device to 1.6 (Donut) I noticed there are new VPN settings you can use to connect your wireless. The four that are offered currently are PPTP, L2TP, L2TP/IPSec PSK, and L2TP/IPSec CRT

UNFORTUNATELY we use a standard IPSec over TCP or UDP, and it doesn't use the PSK or CRT file. I need to manually input the groupID and whatnot.

SO, after some googling I found get-a-robot-vpnc which seems to address my issue.

I also found this post and from all I can tell, it has successfully worked for some people.

BUT my device isn't giving me any such love. My current error reads:

D/vpnc service( 5587): Attempt to read vpnc process id did not return anything

we'll see how far I get on this problem. My guess is it's a permissions problem that will be easily solved...

blogger and andriod

so far, no love for an android app that will post to blogger.

the most i can find is http://mobile.blogger.com which seems to require SMS or MMS

cyanogenmod and memory

i was running into memory problems with my android dev phone.
easy enough to fix: just cleared out my Dalvik cache after upgrading to a new cyanogenmod on my ADP1

adb remount
adb shell rm -rf /data/dalvik-cache/*
