Various jmap questions

1) Does the (default?) -all mode include unreachable (but not yet collected) objects?
2) Do both the all and live mode include weakly referenced objects?
3) HotSpotVirtualMachine#dumpHeap() returns an InputStread (that is dumped to stdout in drain()). I assume the reason for this is to display progress/debug messages, correct?
4) When dumping a remote VM process (through jsadebugd), I assume that the dump file is created on the remote system, correct?
5) Is there any news on the development of a library to read HPROF snapshots?

By default jmap -histo and -dump will dump all objects - this includes unreachable and weakly reachable objects. If you use the "live" sub-option then it triggers a full GC first and this means the histogram or heap dump will have only strongly or softly reachable objects. I hope that helps with #1 and #2.
The dumpHeap method that you have found is an internal method. The input stream that it returned is used to read any output messages from the dump operation.
The jsadebugd daemon is used for connecting to core files or hung processes on remote machines. If you use the heap dump tool then it will be generated on the remote system.
For the HPROF question I would suggest going here:
https://heap-snapshot.dev.java.net/
I hope this helps.

How do I cut and paste sets of lines for use in various Math questions?

How do I cut and paste sets of lines for use in various Math questions?

Thank you for your reply. My problem is much simpler than you are thinking. As a teacher I prepare sheets with random number generators.
EG. 256 + 389= ______    or         467
                                             - 384
       469 + 753= ______
or 5)750
On a PC I was able to start a page of A4 with one set and then drag and drop down and across the page.
On my Macbook I can get the numbers in but the lines do not copy. I asked at one of my One to One sessions and it had my 'trainer' stumped. He said he would make enquiries but so far no news. I am using Numbers.
I hope I have explained my 'problem' satisfactorily.

Various Workflow Questions

I'm new to workflow and I'm trying to figure out the best way to construct my app.
First, what is the best method of generating the item key?
Second, when creating a new process how are the attribute values set? CreateProcess doesn't have any method of doing this. Would I need to use SetItemAttr? How would it react if the item didn't yet exist (as createProcess would not have been called)?
Third, what is the best practice for storing data? One could conceivably store the data in tables of their own and not use the attributes at all. They could also store it in both their own tables and the attributes (which seems redundant to me). They could also just use the attributes for storing data (as the examples in the Workflow guide seem to do).
If I only store the data in the attributes, how would I go about presenting it to my users on various web pages?
Perhaps the solution is to store the data in an initial table, load it into attributes during the first function, only access it in the attributes until a final decision is made, at which point the last function would take the data in the attributes and store it in the final table?
Thanks,
Tom

1) Usually the item key is derived from the primary key of the application object being handled by the workflow. For example, in a requisition workflow, a good item key would be the requisition number. The item key does not have to be meaningful, though; from a workflow point of view the main point is that the item key and item type combination must be unique.
2) Yes, SetItemAttr is the right way to set item attributes, and you're correct that CreateProcess must be called first. The best order in which to call the APIs is:
CreateProcess
SetItemUserKey
SetItemOwner
SetItemAttr...
StartProcess
CreateProcess and StartProcess are required; the Set... APIs are optional, if you want to set any of those values. If you do not need to set anything, you can call LaunchProcess instead, which combines CreateProcess and StartProcess in one wrapper; but note that LaunchProcess does not give you any opportunity to set any values in between creating and starting the process.
3) Item attributes are basically meant to hold the information that the workflow process itself needs to use. There is a trade-off between the convenience of storing global process data in item type attributes and the overhead incurred by loading item type attributes when a process instance is created. So we recommend that you do not use item type attributes as a denormalized data store. Instead, always refer back to the base application to retrieve up-to-date values. Minimizing the number of item type attributes will improve the performance of your workflow process. Also, runtime workflow information is usually purged from the WF tables at some time after the process is complete, so any information that you want to access from your own application should be stored back in your own tables.
We recommend that the following types of information should be defined as item type attributes:
- Information required by notification messages, such as the display format of a currency value
- Information required by function activities, such as values that link back to applications data like a person_ID
- Information maintained by a workflow activity, such as data for activities that identify who to forward information to and from in a loop construct
- Business event messages required by Send or Receive event activities, or event details required by Raise event activities

Various Network Questions

Hey all,
If anyone saw my last post, and is curious what's happening with me, my school's IT department essentially told me to "proove it" (which is how support personnal should work, right?), which is what I'm now trying to do.
Regardless, I have a few questions/issues for anyone:
1) I can't seem to ping ANYTHING (except myself and my school's domain) without receiving a 100% packet loss. Is this because I'm behind the network? That's just a guess on my part, I could always ping outside domains back on my home network, but here I can't ping anything. It boggles my mind! Any other possible causes? I'm still connected to the internet, no doubt.
2) Is it possible to see a netstat that shows the port connections? I'm using the Network Util. right now, for simplicity, but the terminal isn't a problem for me.
3) Is it possible to do a traceroute from behind a big network, such as my college campus's? So far, I have failed. Perhaps this is related to #1....
Thanks in advance!

>1) I can't seem to ping ANYTHING (except myself and my school's domain) without receiving a 100% packet loss. Is this because I'm behind the network?

I'm still connected to the internet, no doubt.
There is a multitude of reasons why you can't ping. If you're on a private network you don't have a direct connection to the internet, and whatever you talk through might not pass ping packets. This could be a proxy, a router, a firewall or any number of other devices.
In short, a lack of ping response does not necessarily indicate a lack of connectivity.
>2) Is it possible to see a netstat that shows the port connections? I'm using the Network Util. right now, for simplicity, but the terminal isn't a problem for me.
netstat -a will show a list of all active connections on your machine.
3) Is it possible to do a traceroute from behind a big network, such as my college campus's? So far, I have failed. Perhaps this is related to #1....
This is almost certainly related to #1. If you can't ping through your network edge it's likely you can't traceroute, either.

Jmap question

Hi all,
i'v got a strange error while trying to dump a java process memory with jmap tool.
user@server #> jmap -dump:format=b,file=heap.bin 95261
95261: no providers installedwhat's wrong with it?
my OS is freebsd, jdk 1.6.0:
Java(TM) SE Runtime Environment (build 1.6.0_03-p4-root_14_mar_2008_15_10-b00)
Java HotSpot(TM) Server VM (build 1.6.0_03-p4-root_14_mar_2008_15_10-b00, mixed mode)
Thanks.
Edited by: phront on Nov 5, 2008 6:56 PM

It looks this jdk does not have attach providers so you are seeing this msg.
This jdk is not from Sun. I do not know who supplied this jdk to you. You need to check with them and see
why the attach providers are missing in the jdk. May be they do not support the attach on demand.
If they support -F option try it which uses the Serviceability agent. Different mechanism to get dump.

Various AppleScript Questions

Hi all,
I am a newbie to AppleScript, so please be patient.
I am trying to write a script that automatically performs the following actions which I have to do regularly to a spreadsheet I get:
Delete the first two rows
alter the top row to be a title row
do three certain "search and replace" actions (replace "I1" by "1", case sensitive, full words only)
categorize and sort by two columns
set one certain column to "number" format
apply category sums to a certain column
Optionally: move some columns to a different position
I am now as far as this (by reading some posts in this forum):
tell application "Numbers"
activate
set myDocName to name of document 1
tell document 1
tell sheet 1
tell table 1
remove row 1
remove row 1
-- How to change the top row to be a title row??
end tell
end tell
end tell
end tell
I suspect that the next things I need have something to do with changing the properties of rows and columns, but I did not find an example of the necessary syntax. Can anybody provide a hint? A link to some documentation would be really nice!
Thanks a lot

You suspect wrongly
If you insert in your code the instruction
get properties of row 1
you will discover that there is no property linked to the row status.

THE source of information is the application's AppleScript's dictionary which you may access thru
Script Editor > File > Open a dictionary…
What you asked can't be done with vanilla AppleScript.
It would require the use of GUI Scripting.
http://www.apple.com/applescript/uiscripting/
Defining headers is simple:
Setting cells format is simple too.
The dictionary states:
format (automatic/checkbox/currency/date and time/fraction/number/percent/pop up menu/scientific/slider/stepper/text) : The cell format of the range's cells.
Your Search/Replace request may be done thru vanilla AppleScript but it would be long and awful.
AppleScript is unable to get the formulas. It get only the values so, to fit your request you need to:
+scan every cell+
+get and save the cell's format+
+set the cell's format to text+
+get the cell's value.+
+if it contains the word l1, replace it by 1+
+if you replaced something, set the cell's value to the new string+
+reset the cell's format to it's original one+
+continue the scan.+
I didn't tested but, according to the dictionary, sorting thru vanilla AppleScript can only be done with a single key column:
sort v : Sort the rows of the table.
sort table
by column : The column to sort by.
[direction ascending/descending]
[in rows range] : Limit the sort to the specified rows.
Other tasks would be more difficult because you must find a way to GUIscript dialogs available thru Inspectors
As far as I know, some request can't be responded because there is no tool to do that (we can't drag column label as requested to move a column)
Have fun.

Various Logic Questions.....

Planning on getting a 15' Macbook Pro next month. Do I need to upgrade the ram to effectively use Logic Express?
Will I still be able to use my Garageband jam packs or does it come with these?
Thanks!
Jay

Hi,
RAM: The more the better. But with 2GB Logic should run ok for basic tasks. If you want to make heavy and excessive use of the EXS24 Sampler, you may consider upgrading to 4GB. But I run LE on a "small" Macbook with 2GB and never had any RAM issues. CPU and Harddisk Speed is the bottleneck, not RAM.
Loops&Jam Packs: Yes, you can use them. LE doesn't come with extra Jam Packs. If you like these Gizmos, consider buying Logic Studio which includes a really big library of sound, packs and so.
If i could turn back time... I would say that buying Logic Studio is the better decision. I often catch mayself thinking about upgrading to Studio. With a MacBook Pro you have the right gear for this. Don't hesitate. Buy Logic Studio

Various newbie questions!

How do I tell if I am connected to WiFi or on Verizon data? Is there another symbols selection page that I am missing to use the ^ character? And perhaps the most frustrating of all, I can not "tap" the video icon to start/stop taking a video. Thanks for your time in advance.

1)On your home screen, there is a little black screen on the top, that is for your notifications. If you tap on that part you will see a "dot with 3 semi circles", that is your WiFi connection. If connected, it will be show up.
Another way to check. Go to Setting > Wi-Fi > Wi-Fi networking > On. It will tell you which one you are connected to.
2)For you Video Camera, once you load it up, just tap the the screen and it will start, and tap the screen again, it will stop
3)On the keyboard, on the far bottom left corner you will see the key "&123". Click on that and it will bring up additional characters and symbols. Then right on top of that key, there is right arrow key "->". Click on that right arrow key and it will bring up even more additional keys and symbols. I believe that is where you will find the exponent key "^". Also if you press and hold a key, it will bring up different types of ASCII characters, but not for all key, only some.

I can no longer use Photoshop for UI Design (PS CC + Retina display)

Since I bought the new MacBook Pro with retina display, Photoshop can no longer be an option for user interface design.
I'm runningn the last Photoshop CC update, and each file opens at 50% size compared to other standard displays, which makes working with old files frustrating. Besides, creating a new 1200 wide document to start a web design makes no sense (too small).
- View > 200% isn't a solution, things look pixelated.
- To increase the resolution from 72ppi to 220 (retina display) isn't a solution, it doesn't affect the document size
- Working with a document with 2x size can't be a solution: I should create everything with a 2x size (stroke, shadows, even rounded corners), which would push PS even more far away from being a tool that can be used for UI design.
Should we just expect that PS on a high-res display behave like that? I don't think so. Besides, the guys of Sketch App (a tool for UI design, that I'm currently working with) found a solution - the retina canvas option:
You can choose to see bitmap images pixelated, but still the vectors will look exactly like on the browser. By choosing to see the document at the same size but with more details, retina users can enjoy the power of the new MacBook while working on UI design.
Am I missing something? Should we expect this option in Photoshop too?

It upsets me to see that this was initially posted almost a year ago and there was no answer. There also seems to be no answer to various other questions about the same issue. Adobe do you care? I am already guessing that Apple doesn't. I know that Adobe has been at the top of this industry. Time for someone else to compete? This is a highly frustrating issue for UI and web designers.

Mac Pro 3,1 with ATI Radeon 5770 + 30" Apple Cinema Display Problem

Ok guys/gals,
First of all I apologize for the thread as there have been previous posts in the past referrencing various different questions and setups, but I have a problem.. It's a little bit of a noob question so sorry in advance BUT..
What is the correct way to set up the 30 inch with the 5770? I have an old 3,1 (early 2008) that I've upgraded with various hard disks, SSD and 12 gig RAM. I removed the stock Nvidia Card and replaced it with this one but I am having problems that cause the Mac to slow down and the display to go all "fuzzy" or have streaking greenish lines (which you can only see against a black backdrop).
Currently, i have it going into the DVI port with the USB and FW extensions just lying around.. I've read something about needing to source more power from the motherboard to power the display, but I am not sure what to do... It's hit or miss really... every time i want to play say Starcraft 2, i need to restart my Mac Pro else it gets extremely sluggish (graphics)...
Is my Mac dying? or am i not powering the 30 inch correctly? If not, then I am confused between display ports and dual power (active) mini display ports.. can someone please point me in the right direction?
Apols for the long note, but am pretty good with computers but this is just annoying the sh*t out of me and has been for a while...
(PS - I CANT WAIT FOR THE NEW MAC PRO !!!)
Thanks,
NK

@ Hatter
Yup prior card was 8800gt and new card is nice and snug. 10.8 was not clean install, was upgrade. Ill try safeboot although not sure how/why that will fix any long term issues i have (which are random).. Trying 10.7 i had the same issues and was hoping that 10.8 wld fix.. Why go back to 10.6.8 when it should work in todays day and age? :(
@ Grant
Have done that now although not sure why something like this is not in the owners manual?!
Thanks for the help/suggestions so far guys, much apprec.. Feels like my pro is dying on me slowly but surely...
Any other bright ideas?

How to I get access to the Captivate object in javascript within an HTML file?

I'm still struggling with this and would really appreciate any help/guidance you can .
here's what I've got right now:

document.write("<P><H1> g_bIsInternetExplorer=" + g_bIsInternetExplorer + "</H1></P>");
document.write("<P><H1> setting objCP....</H1></P>");
var objCp = g_bIsInternetExplorer ? Captivate : document.Captivate;
document.write("<P><H1> set objCP....</H1></P>");
var description = objCp.cpEIGetValue("m_VarHandle.cpInfoDescription");
document.write("<P><H1> description=" + description + "</H1></P>");
I've published the captivate project.. I then launch it and then launch the html file that has this code in it
It does everyting up thru and including line 3
But it seems to fail on line 4..
Any ideas /suggestions?
Thanks in advance.

Hey Jim - thank you thank you thank you
Here's what was up with my code:
This worked:
alert("about to set objCP...");
var objCp = document.Captivate;
alert("completed setting of objCP, about to set get cpInfoDescription...");
var description = objCp.cpEIGetValue("m_VarHandle.cpInfoDescription");
alert("description=" + description);
This did NOT work:
document.write("<P><H1> AT BEGINNING </H1></P>");
alert("about to set objCP...");
var objCp = document.Captivate;
alert("completed setting of objCP, about to set get cpInfoDescription...");
var description = objCp.cpEIGetValue("m_VarHandle.cpInfoDescription");
alert("description=" + description);

I'm guessing the 2nd didn't work because i tried to get the captivate object AFTER the script wrote something to an HTML file. I'm ultimately trying to get Captivate to generate a report for the user to report out what they did in response to the various quiz questions in the course (in HTML in table). I've posted a query on how to do this here: http://forums.adobe.com/message/5120417#5120417
Any chance you could take a look at this posting and let me know your thoughts on how best to do this .. It seems like this would be a fairly common thing to do .. It comes stock in Articulate Storyline (through their 'Report.HTML') but I haven't found a comparable one in Captivate.
Thanks again!

HT5622 My Ipod Classic shows a red circle with a cross in the middle. I've completed diagnostic tests which have popped up, however any HP/FW/Hard Drive tests freeze the ipod, as if the hard drive won't spin. What do I do?

My Ipod Classic shows a red circle with a cross in the middle. I've completed diagnostic tests which have popped up, however any HP/FW/Hard Drive tests freeze the ipod, as if the hard drive won't spin. What do I do?
After holding down the Select and Play/Pause button, I was able to restart the Ipod and then it brought me to a Diagnositc test. I have tried doing both the Mannual and Annual test on the ipod however in each test, the ipod freezes on different access tests. The HP (headphones) test, shows the headphones are detected, but then if it tries to play a song to make sure they work it freezes and goes back to the red cross. I have looked at various other questions regarding the FW cable, however I don't believe i have such a cabel. Then the Hard Drive test freezes up and I can hear a ticking noise coming from the drive but it doesnt seem to be spinning. Alongside these test issues, any computer cannot see the Ipod when plugged in (including itunes). Therefore some tests for the USB drive cannot be completed. I do not recall dropping it badly, though I have dropped it previously. Does all this mean there is damage to the drive? Should I instead take it to an apple store?
Many Thanks

The stats look fine. Try the DFU Restore method shown in Corrupt iPod classic. It may pay to disable any anti-virus software and use the staged transfer method to reload data, assuming you get that far.

Dynamic app creation using MXML?

I'm working on creating a small quiz application which will
be driven by pre-formatted external XML. I have designed various
custom question canvases for each of the question types (MCQ, short
answer, match-pairs etc.) and I'm wondering if there is some way to
implement the main application using MXML instead of ActionScript?
I've managed to hard-code the order of the questions, knowing
which canvases are needed in which order, but I need to be able to
detect the question type from the XML (that bit I can manage) and
then add the appropriate question canvas component in order in my
tabNavigator.
Essentially, I'm trying to replicate the function of a
switch:case clause in MXML. Does anyone know if this is possible?
I've started trying to implement it in ActionScript, but I'm a bit
of a newbie to AS3, and I keep getting errors I don't understand,
like "Access of undefined property" where I'm referring to an
object I've just declared and instantiated in the previous line of
code. E.g (anywhere I use mainPanel):
<mx:Script>
<![CDATA[
import mx.controls.Text;
import mx.containers.Canvas;
import mx.containers.Panel;
var mainPanel:Panel = new Panel();
Root.addChild(mainPanel);
mainPanel.layout = "absolute";
mainPanel.setStyle("left", 10);
mainPanel.setStyle("top", 10);
mainPanel.setStyle("right", 10);
mainPanel.setStyle("bottom", 10);
var testPage:Canvas = new Canvas();
var numQuestions:int = quizQns.childNodes.length;
var qTypes:Array = new Array(numQuestions);
var textLine:Array = new Array(numQuestions);
]]>
</mx:Script>

You can declare and initialize variables outside functions in
your script block, but for most else you need to do it in a
function. I would continue learning AS3 as it will give you real
flexibility and power.
<?xml version="1.0"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
creationComplete="init()">
<mx:Script>
<![CDATA[
import mx.controls.Text;
import mx.containers.Canvas;
import mx.containers.Panel;
private var mainPanel:Panel;
private var testPage:Canvas = new Canvas();
private var numQuestions:int = 10;
// private var numQuestions:int = quizQns.childNodes.length;
private var qTypes:Array = new Array(numQuestions);
private var textLine:Array = new Array(numQuestions);
public function init():void {
mainPanel = new Panel();
addChild(mainPanel);
mainPanel.layout = "absolute";
mainPanel.setStyle("left", 10);
mainPanel.setStyle("top", 10);
mainPanel.setStyle("right", 10);
mainPanel.setStyle("bottom", 10);
]]>

HT201318 how to get a refund for icloud storage

I purchased icloud storage I do not now need and it said I can get a refund within 14 days, but does not say how.
Does anyone know how please?

I have just done this and it works. Dial 1-800-275-2273, this is a US number so if calling from the UK, use Planet Talk to get this at 0.5p per minute. Go through the voice recognition program. You will finally be put through to a representative who will ask you various security questions, Apple ID, home address, last four numbers of credit card etc. The refund, which is refundable within 15 days of purchase, is done within minutes. A bit of a performance to get through, but once you do, its an easy process. This is probably too late now, but maybe be useful for next time.

Error Message of "undefined"

I get the following error message when launching a Captivate
eLearning Course from an LMS. The error message is "undefined".
There is not any error number included. Just an "OK" button. The
course launched just fine from 3 other PC's. My course has 16 video
clips (FLV's) and various Quiz questions. It is published to SCORM
1.2 and is running on a reputable LMS (Rustici Test Track). I am
assuming that the message is related to the javascript that is
trying to find the SCORM API. The word "undefined" is included in
the script. The other puzzling issue is; why does the course launch
fine from 3 PC's and not from a 4th. There ARE some minor
variations in the configuration of the 4 PC's, but they are
presumed to be minor.
I am not a javascript expert, although I can read and
troubleshoot many of the scripts that are involved in the
SCORM-related script included in a Captivate movie (course).
Has anyone seen this error message when trying to launch from
a SCORM Compliant LMS?

Thanks for your suggestions from when we talked off-line. I
tried changing some of the launch parameters on the Test Track LMS
and I was able to launch the course from the home PC where I had
seen the error message. I also had the pop-up blocker causing some
issues. I turned that off and was finally able to launch the course
with no errors. Thanks for your help!
