Is it safe/acceptable to build on the pfil STREAM module?

Does anyone know if it is safe to build on top of the pfil module by calling its public interfaces? I need to build a STREAM module to intercept TCP packets and was in the process of essentially duplicate all of the code in the pfil module, when I realized it would be much simpler to call pfil_add_hook directly. However, the pfil.h header is not provided with the package (not sure if there is a developer package I need) so I don't want to just assume these are truely public interfaces open to modules beyond the ipfilter module.

Some Internet services use UDP, which means that you have to allow incoming packets. Conceivably there might be an unknown remote exploit in Firefox that would make it unsafe to allow that traffic. No one can absolutely guarantee that there isn't. But if it's a well-known site and a well-known protocol, you're almost certainly OK.

Safe mode in build 9926

how do you run in safe mode for build 9926?

how do you run in safe mode for build 9926?
There is more than one way to go to safe mode.
If you can still logged in to 9926, this is the fastest way......
Right click at Start button > select Run > in the box, type msconfig > OK > click Boot tab at top > check the box "Safe boot " > OK > Restart computer.
*** After you are done with running in Safe Mode, repeat the steps, but this time, make sure you UN-check the box so that you can go back to "normal" mode.

If all the photos from my iPhone 4s Camera Roll show up in iPhoto under Library- Photos, is it safe to delete them from the iPhone and not risk losing them?

I am getting messages about being out of space on my phone for taking any more photos. I am scared to delete anything with all the photo stream and syncing that happens cause I don't want the photo to delete in many places at the same time.
So, 1) when is it safe to delete from the iPhone? 2) I feel like I have multiple copies of photos stored between the phone, Photos Library in iPhoto and all my albums in iPhoto. Is there a best practice document on how to manage your photos for space savings?
I've looked, but can't find my answer clearly in the forums.

IF you have successfully imported your pictures to your Mac http://support.apple.com/kb/HT4083 then it's safe to delete it from your phone.
If you want the pics back on your phone, just sync them back using itunes http://support.apple.com/kb/HT4236

I have a production mobile Flex app that uses RemoteObject calls for all data access, and it's working well, except for a new remote call I just added that only fails when running with a release build. The same call works fine when running on the device

I have a production mobile Flex app that uses RemoteObject calls for all data access, and it's working well, except for a new remote call I just added that only fails when running with a release build. The same call works fine when running on the device (iPhone) using debug build. When running with a release build, the result handler is never called (nor is the fault handler called). Viewing the BlazeDS logs in debug mode, the call is received and send back with data. I've narrowed it down to what seems to be a data size issue.
I have targeted one specific data call that returns in the String value a string length of 44kb, which fails in the release build (result or fault handler never called), but the result handler is called as expected in debug build. When I do not populate the String value (in server side Java code) on the object (just set it empty string), the result handler is then called, and the object is returned (release build).
The custom object being returned in the call is a very a simple object, with getters/setters for simple types boolean, int, String, and one org.23c.dom.Document type. This same object type is used on other other RemoteObject calls (different data) and works fine (release and debug builds). I originally was returning as a Document, but, just to make sure this wasn't the problem, changed the value to be returned to a String, just to rule out XML/Dom issues in serialization.
I don't understand 1) why the release build vs. debug build behavior is different for a RemoteObject call, 2) why the calls work in debug build when sending over a somewhat large (but, not unreasonable) amount of data in a String object, but not in release build.
I have't tried to find out exactly where the failure point in size is, but, not sure that's even relevant, since 44kb isn't an unreasonable size to expect.
By turning on the Debug mode in BlazeDS, I can see the object and it's attributes being serialized and everything looks good there. The calls are received and processed appropriately in BlazeDS for both debug and release build testing.
Anyone have an idea on other things to try to debug/resolve this?
Platform testing is BlazeDS 4, Flashbuilder 4.7, Websphere 8 server, iPhone (iOS 7.1.2). Tried using multiple Flex SDK's 4.12 to the latest 4.13, with no change in behavior.
Thanks!

After a week's worth of debugging, I found the issue.
The Java type returned from the call was defined as ArrayList. Changing it to List resolved the problem.
I'm not sure why ArrayList isn't a valid return type, I've been looking at the Adobe docs, and still can't see why this isn't valid. And, why it works in Debug mode and not in Release build is even stranger. Maybe someone can shed some light on the logic here to me.

what i did is, I unzipped the source code into a folder
hybridstore.
I opened the flexbuilder : File -- new -- flexproject ( i
have selected) then i have given name to my file (hybridstore) ,
and set the path to the hybridstore folder where the source code

Hi,
thanks for your reply,
I have tried to open using file import, but still it is not
working.
in the readme file for this application , contains how to
Creating a project in Flex Builder for the Hybrid Store
application:
Name your default application catalog.mxml.
Prevent Flex Builder from generating an HTML wrapper: select
Project > Properties. Select the Flex Compiler page, deselect
the Generate HTML wrapper file option .
Create a Run configuration for your project but deselect the
Use defaults option and instead assign the Run setting to the

To enable debugging of the Hybrid Store application you must
create a copy of hybridstore.html. Open it in an editor (you can

My MacBook Pro doesn't start; in safe mode shift CMD V the message "disk0s2: media is not present" is written on the screen repeatedly but the MacBook doesn't start. Do you have any ideas of why this should be or what I should do to resolve this?

My MacBook Pro doesn't start; in safe mode <shift CMD V> the message "disk0s2: media is not present" is written on the screen repeatedly but the MacBook doesn't start. Do you have any ideas of why this should be or what I should do to resolve this? Thanks Eamonn

Thanks for these suggestions: I have tried safe mode re-starts (both "verbose" and simple "shift" + power) to no avail. I get the error message "disk0s2: media is not present". Following this I inserted the installation disc and from there ran disc utility. The "Verify Disk" indicated an error " invalid sibling link" which it could not repair.
I also tried to completely re-format/erase the disk, but again got an error message "disk object invalid or unable to serialize".
Any ideas of what could be causing this or the best solution? I fear I am fast running out of options.

Hate to suggest this, but you need to ask in the Flash forum. This forum is for Acrobat.

Any tutorials on how to use the daily build of the Flex SDK to create Flash Player 10 content?

Is there a tutorial on Adobe on how to use the daily build of
the Flex SDK to create Flash Player 10 content?

The approach you take might depend on a few things, but it boils down to using mouse interactive coding to trigger whatever effect you eventually realize. The code you use will depend on the version of Actionscript you plan to use.
You could make this as a movieclip that is normally stopped at its first frame and when you mouseover or click the movieclip, it animates along its own timeline to its enlarged state. If the thumbnail is very small and the larger version is substantially larger, and both need to be clear images, this might be the better approach.
If this only involves enlarging something, you could also probably realize it just using Actionscript Tween coding rather than timeline animation.

Final cut pro X is supposed to accept AVI. Yet the AVI files my client gave me don't work. I know there are softwares that can convert AVI to APPLE PRORES, but does that affect the quality of the media ?

Final cut pro X is supposed to accept AVI. However the AVI files my client gave me cannot be imported in my Final cut pro X. I know there are softwares that can convert AVI to APPLE PRO RES, but does that alter the quality of the media ?

There are apps that will give you tech specs on files. I think Media Info is one. Most likely it's in done delivery codec like DiVX. AVI is a piece of **** as a container anyway and should have been completely abandoned years ago.

How to validate multiple lines which is exist in the form builder at the same session

Hi All,
we are working on oracle Forms personalization to trigger the message at the point of saving multiple lines rather than requiring each line to be save individually. Currently the oracle form is allowing to user to enter two distinct lines that have same resource and basis type in BOM.
Currently the Oracle form is allowing to enter the duplicate combination and not giving any error message even we enter the same combination of data.
As per the customer requirement, they don’t want to validate the data while creating the records but when they try to save the form, in that case it should validate all the records at a time then need to display the appropriate message.
Customer don’t want to customize the Oracle standard form. Here we have only option to use form personalization or through custom.pll.
Any idea on how to validate multiple lines which is exist in the form builder at the same session as before inserting the record itself need to perform the validations for all the records.
Thanks for your help in this regard.
Regards,
Thirupathi

you can write a post script which will do the necessary tasks.
I mean, once you are done with inserting records into these tables, exeute another procedure which will insert these "extra" records, based on some logic.
you may not be able use DB trigger as it may generate mutating error or if you don't write it carefully, it will go into recursive loops as you are refering to same tables.

I received a pop up regarding security certificates when opening a PDF document today. Is it safe to say "yes" to the installation of the security updates?

If you opened it with Adobe Reader, then yes: "Yes" is safe (I just did the same thing one minute ago).

Creating a template in Pages is straight-forward as answered here previously. Is there and equivalent for iBooks Author which can start with a blank page and build up the template as required? or can one only adapt a ready made template?

Creating a template in Pages is straight-forward as answered here previously. Is there an equivalent for iBooks Author which can start with a blank page and build up the template as required? or can one only adapt a ready made template? This has proved unsatisfactory to me so far. Lines are left in etc.

There are two basic menus for fonts - one from the main menu bar and one from the toolbar. You can also bring up the font manage dialog.
I don't recommend trying to hard to force an otherwise foreign font, as it inevitably needs to be usable/supported on iOS as well, and that can get tricky w/3rd party fonts, as an example, even with the expanded font support in the latest iBA.
If you need to discuss fonts more, I suggest starting a new thread....preferably with a slightly more brief title, thanks.

[SOLVED] How to add modules to build with the kernel?

Hello i´m trying to learn how to build my own custom kernel and doing it the arch way https://wiki.archlinux.org/index.php/Ke … raditional. But unfortunately dm-crypt was not included in the kernel so it all failed.

I have never don any of this before and have no idea of how to add a missing module to the kernel i´m building. So i search on internet and had a very hard time finding a good guide for this but i fond one possible solution. https://www.kernel.org/doc/Documentatio … odules.txt

Reason enough IMO. But anyway... you refer to the Traditional build method in the wiki, but is it possible you didn't really read it? Or maybe you only skimmed it? Did you run make menuconfig? Did you try to build everything in instead of using modules? That mkinitcpio output suggests that you did.
As suggested there for first-timers, it's a good idea to start with a kernel configuration that is known to work - the Arch config is the obvious choice, but there are other sources e.g. http://kernel-seeds.org/ .
