What are Microsoft- or other's-best practice or recommendation of Disk usage, CPU usage, memory usage monitoring to prevent system trouble ?

We use win2003,win2008,win2012 servers.
I heard somewhere that Microsoft recommendation threshold of disk usage monitoring is ( free disk space >= 15- 20 %) , if I remember correctly, but how about CPU usage and memory usage monitoring ?

What are default Zend Session handling best practices to prevent Cross Site Request Forgery?

I have enjoyed the David Powers book Adobe Dreamweaver CS5 with PHP: Training from the Source - and have put many of the examples into practice. I have a security related concern that may be tied to the Zend::Auth example in the book. While this is installed an working on my site:
<?php
$failed = FALSE;
if ($_POST) {
if (empty($_POST['username']) || empty($_POST['password'])) {
    $failed = TRUE;
} else {
    require_once('library.php');
    // check the user's credentials
    try {
      $auth = Zend_Auth::getInstance();
      $adapter = new Zend_Auth_Adapter_DbTable($dbRead, 'user', 'login', 'user_pass', 'sha1(?)');
      $adapter->setIdentity($_POST['username']);
      $adapter->setCredential($_POST['password']);
      $result = $auth->authenticate($adapter);
      if ($result->isValid()) {
        $storage = $auth->getStorage();
        $storage->write($adapter->getResultRowObject(array(
          'ID', 'login', 'user_first', 'user_last', 'user_role')));
        header('Location: /member/index.php');
        exit;
      } else {
        $failed = TRUE;
    } catch (Exception $e) {
      echo $e->getMessage();
if (isset($_GET['logout'])) {
require_once('library.php');
try {
    $auth = Zend_Auth::getInstance();
    $auth->clearIdentity();
} catch (Exception $e) {
    echo $e->getMessage();
Apparently, there is very limited protection against Cross Site Request Forgery, where the resulting SessionID could be easily hijacked? I am using the Zend Community edition (I have 1.11.11).     I have an observation from a client that this authentication is not up to snuff.
To boil it down:
1. Is there a Zend configuration file that might have some settings to upgrade the Session and or authentication security basics? I'm wondering specifically about the settings in /library/Zend/session.php? Ie secure the session against a changing user IP, and invoking some other session handling stuff (time-out etc).
2. If I understand it correctly, "salting" won't help with this, unless it's added/checked via a hidden POST at login time?
Ideally, the man himself, David Powers would jump in here - but I'll take any help I can get!
Thanks!

Might ask them over here.

1-Do some more reading about a Windows "upgrade version" which, according to my experience, does NOT require you to format your drive... it upgrades over what you have, without disturbing installed programs... at least that is what happened the ONE time I installed an upgrade version, so I can't give a 100% assurance it will work that way with your computer... search link for all things Microsoft http://search.microsoft.com/search.aspx?mkt=en-US&setlang=en-US
2-Depending on the hardware you have, you may not be able to run CC programs well, if at all
3-CS6 is 3+ years old and is the ONLY non-CC version still being sold... unless you can find a "legal" CS5 somewhere

What are the names of the ports in my MacBook Pro that I can plug an external monitor into?

You have Thunderbolt or Mini DisplayPort. If you know which external display you want or you already have it, look at the ports it has got and get a Mini DisplayPort adapter for it. There are Mini DisplayPort adapters for DVI, VGA and HDMI.
Most external displays have DVI, VGA or HDMI. If you can use HDMI, use it, because it will provide much better quality. See > http://support.apple.com/kb/HT4241?viewlocale=en_US&locale=en_US

(Swing) Reading fields from other forms - Best practice

Hi All,
I have been learning Java and Swing through NetBeans (quite a cool way to do it). I would like some 'best-practice' advice please. Google and search on this forum are normally my friends, can't find anything relevant for this though. I have created an application that seems to be functional, all my navigation is through tabs.
To make my app portable I have created a ?Settings? part. To save having another tab, I have basically copied the way NetBeans deals with opening the ?About Box? in its example, and have set-up fields in here. This essentially opens a JDialog with fields through an option in the menu.
I figure the best way to store the data is in a simple text file, and have the application read the values on start-up? Then when somebody changes the fields and saves it just overwrites the text file with the new values. I am not sure how to best read these in though, I can?t find a way of reading direct from the JDialog (i.e. var.getText()) which makes sense as the JDialog will be closed.
Will my best practice simply be writing a class which reads the file, then whenever I need a value just calling the class?
Thanks a lot

You should not be using preference files unless you really know what you are doing. This is one area of the very few areas of Java programming that can have lasting nasty negative affects on a computer that runs the code if done wrong.
If you want the user to save preferences it is better to just use xml. The advantage of preference files is they can be used by multiple programs and are permanent even after the program is done running/deleted/writen-over/forgotten. The disadvantages of preference files is they can be used by multiple programs, are permanent even after the program is done running/deleted/writen-over/forgotten, can cause damage to your OS, may be seen as harmfull by add blockers and/or anti-virus software, may lead to conflicts with other software that uses similar naming schemes, and are pretty much unportable.
You are going to be much better off in the long run learning XML and just saving them there, an added benefit of XML is if you screw something up and it causes your program to no longer run you can easily edit the xml by hand.

What is the guideline and/or best practice for EMC setup on ASM?

We are going to use EMC CX4-480 for ASM storage on RAC. What is the guideline and best practice for EMC setup on ASM?
Thanks for the advice!

Probably a poor choice of words. Sorry.
So basically, I have gotten further, but I just noticed related problem.
I'm using the WebServices(WS) 1.0. I insert an account, then, on a separate WS call, I insert my contacts for the account. I include the AccountID, and a user defined key from the Account when creating the Contact.
When I look at my Contact on the CRMOD web page, it shows the appropriate links back to the Account. But when I look at my Account on the CRMOD web page, it shows no Contacts.
So when I say workflow or Best Practice, I was hoping for guidance on how to properly write my code to accomplish all of the necessary steps. As in this is how you insert an account with a contact(s) and it updates the appropriate IDs so that it shows up properly on the CRMOD web pages.
Based on the above, it looks like I need to, as the next step, take the ContactID and update the Account with it so that their is a bi-directional link.
I'm thinking there is a better way in doing this.
Here is my psuedocode:
AccountInsert()
AccountID = NewAcctRec
ContactInsert(NewAcctRec)
ContactID = NewContRec
AccountUpdate(NewContRec)
Thanks,

What do you find to be best practice when it comes to writing AS code to manage a big app ?

Right now I am considering 3 options:
1) I write all the code in a root component that extends group for example like this:
<s:Application>
     <s:AppGroup>
               <s:List />
     </s:AppGroup>
</s:Application>
So in it I will write the code to manage the list. Ok but Imagine now I have 10 views inside that AppGroup each having a list which needs to be managed. So here comes my option 2.
2) I write code in the AppGroup component to manage what's on it's level and for new level (view for example) I create another component like ViewGroup1, ViewGroup2 etc which extends group or something else and I write code in it to manage what's inside of it. This looks like this:
<s:Application>
     <s:AppGroup>
          <s:ViewGroup1>
               <s:List />
          </s:ViewGroup1>
          <s:ViewGroup2>
               <s:List />
          </s:ViewGroup2>
     </s:AppGroup>
</s:Application>
So this time the code to manage the views will be in AppGroup and the code for managing the Lists will be in the ViewGroup1/2 component.
3) of course sometimes mixed architecture if for example the ViewGroup1 is very simple and doesn't have list but a label or something like that the code could be written in the AppGroup.
What do you think of this code structure? Is my logic good or there's something else considered a best practice at the moment ? Thanks!

Thank you all for the thoughts. Could we please stick to flex only for now...
Currently I have a project where I see this structure:
<Application creationComplete="init();">
     <fx:Script source="MainApp.as" /> - all initialization code is here
     <components /> - many components
</Application>
In the creation complete of the Application which is in MainApp.as, dataProviders are set and a controller class is initiated to which the Application is passed as Object and everything is manipulated from that controller. As you mentioned I guess you can always create additional controllers and pass them the Application or some other components from which they could start controlling so to speak.
I am not sure if this structure is good or not, I started comparing it with mine and I ended up here...
What I see at this point compared to mine is that:
- in the included MainApp.as in Application I have question marks when i type something like "stage" in a function, I needs me to type "this.stage", which I don't like. To me it looks like including is bad and maybe everything should have started with creationComplete in the Application mxml with importing and initiating the controller with passing him the Application right away. Is that correct?
- in the example given above, after MainApp initiates the controller by passing him the Application, the controller looses all of the nice code hints since now the Application is an object... maybe it's wrong for it to be object ? Should it be something else?
Compared to my approach when I separate my logic into AS Group which is then extended as MXML Group. All I have to do is declare the instances in AS which I have as IDs in MXML and voila... I can control them and write their logic with all the nice code hints present.
So basicly at this point you say instead of extending Group in AS every time I want to separate logic, write a controller right ?
Here is what I summarized for now:
1) Create a RootController class
2) Initiate it in the creation complete of the Application passing the Application (as what type - object or something else?)
3) manage all logic in that controller
4) if parts of the application are too complex they can be separated into additional controllers.
5) the RootController can initiate SubControllers which can initiate SubSubControllers
6) to all controllers a component must be passed as a starting point for the logic
Is this correct? If yes, what about the code hinting compared to my approach?
Would be very nice if someone of you could make a very very very simple app with the model you are talking about, or if you have an article you took it from share the link! Thanks!

Moving Mailserver from Xserve G4 to intel, Best practice?, Recommendations?

Hi!
I will receive a new Xserve intel soon and possibly want to move mail services from the currently used Xserve G4 (which is working fine) to the new Xserve intel.
The Xserve G4 is running a heavily modified mail setup thanks to pterobyte's excellent tutorials on fixing, updating, extending, dare I say "pimping" Mac OS X Server's mailserver setup.
What I want to achieve in the long run:
Have Mail services run on the Xserve intel and have the Xserve G4 work as a mailbackup. (They will be connected via permanent VPN, but be in different LANs on different ISPs). They shall be serving email for at least three distinct domains then. (All low volume. currently the G4 is serving a single domain using WGM aliases.) I want (and need) to switch to postfix aliases.
What I need to consider:
My client desperately wants/needs to update to Leopard server once it becomes available. Both Xserve definitely will be upgraded to Leopard Server then.
Time is not an issue at the moment as the G4 is working very well. I want to keep the work at a minimum in regard to the Leopard switch. I am fine with an interim solution, even if it is somewhat inelegant, as long as it runs fine. The additional domains are not urgent at the moment. It will be fine when they transfer to the intel Xserve once we run Leopard.
Questions:
Does it pay to do all the work moving from the G4 to the intel (I'd need to compile and configure all the SpamAssassin, ClamAV, Amavisd-New, etc. again...) move all the Mailboxes, Users, IMAP and SMTP. In regard that there will be a clean install once Leopard comes out. (I am definitely no fan of Updating a Mac OS X server. Experience has proven to me that this does not work reliably.)
Are there any recommendations or best practice hints from your experience when moving a server from PPC to intel?
Thanks in advance
MacLemon

By all means do a clean install. If time is not an issue, make sure Leopard has been on the market 2-3 months before you do so.
Here is what I would do:
1. Clean install of Intel Server
2. Update all components
3. Copy all needed configuration files from PPC to Intel Server
4. Backup PPC mail server with mailbfr
5. Restore mail backup with mailbfr to Intel Server
This is all that needs to be done.
If you want to keep the G4 as a backup server, just configure it as a secondary MX in case your primary is down. Trying to keep mailboxes redundant is only possible in a cluster and a massive pain to configure (Leopard should change that though).
HTH,
Alex

Best practice for CPU and memory usage?

I find my AIR application takes a lot of memory -- usually
>170M. And what is strange is that the memory usage is
increasing (about 4K/s) even when the application is simply sitting
there and do nothing. The CPU usage is supposed to be 0% when the
application is doing nothing, but it's not (usually ~5%). So I
wonder if there is any article about best practice on CPU/Memory
usage.

Those numbers indicate that your application is in fact doing
something. Perhaps you have a timer still running, or work being
done on an enterFrame event?

Best Practice for DS6.2 disk usage

Hi:
We are installing DS6.2 on Windows 2003 SP1 configured with a 10gb OS drive and a 50gb data drive. Both are connected to EMC SAN but are not the same LUN, the data drive is higher end disk. Our initial idea was to install DS on the OS drive and the place the directory instances and the logs on the data drive. After mulling it over it may seem this is not the best practice. Does anyone have any knowledge of the best use of disk or know of any best practice documentation?
Thanks for your help!

What is that exactly and what are the chances my photos and files can be recovered. I would go to the shop but I'm on vacation. Help would be appreciated thanks.

What are the settings to for best quality video for playback on computer?

I'm not having any software or hardware issues. I have tried differnent combinations using AVI, MPEG and WMV and I'm still not satisfied with the quality.
I have used the same settings as my original video and it still is no where near the quality. Maybe this is as good as it gets, any help would be appreciated.
quick rundown
I'm using the recorder on my computer to record my screen and voice to create video tutorials for my students to watch on-line. This creates a 720x480 AVI file and has good quality.

What is the best preset to use for HD-lite?
The best is one that matches the Source Footage 100%. Unfortunately, with that variation on HD, I do not think that PrE, even PrE 10, will be able to come close. PrPro, however, does have the ability to do Custom Sequences (think a bunch of mini-Projects inside of a Project), and one can match odd Frame Sizes, FPS, etc.. I was hoping that PrE 10 would have Custom Presets, but it did not show up. This limits PrE to standard Frame Sizes, which is not what most video screen capture programs offer. Your footage does not match to any real HD-Lite Frame Sizes, so you will still have the same problem.
It does appear that your program, while different than the TechSmith Camtasia, does use the TSCC CODEC. This will give you a bit more info. Also, though you do not have Camtasia, or CamStudio, I think that the article, that I linked to above, might be of use.
Now, what options does your video capture program offer for output?
Good luck,
Hunt

What are iCloud email other SMTP servers?

I went to Settings<Mail, Contacts<iCloud account<Account<Mail<SMTP. What do "other SMTP" servers do. One of those is a gmail server. What does it mean?

I've had a similar lack of success on my iPhone 3G. There are three ways in which this has failed:
• I've carefully copied the SMTP settings from a working Mail.app account, but the iPhone 3G consistently tells me that the account cannot be verified, which prevents it from being added to my list of SMTP servers.
• I've also tried syncing mail accounts using iTunes, which just causes iTunes to hang.
• Lastly, I set my personal email address (personal web domain) to use the SMTP server for a gmail account. This will send the email, but it appears to the recipient as coming from the gmail address, NOT from the personal address.
In all three cases, iPhone's SMTP behavior has proved to be completely unacceptable. I may be returning my iPhone in the near future.
