Need help with a terminal command
Ever since Lion, or maybe even earlier, I am fighting a losing battle against memory leaks on my MacBook Pro. Safari for example takes over time 2GB+ for just 2 or 3 tabs open with almost no extensions active. Really strange.
Someone told me about the "purge" command in Terminal to free some of the sequestered memory, so I am doing this a few times a day to be able to use Photoshop, Keynote, Premiere and other stuff concurrently without opening and closing apps like I did 10 or 15 years ago, remember those days?
So here are my 2 questions:
Will this frequent "purge" command harm anything in the long run?
If no, is it possible to automate this "purge" Terminal action somehow? Maybe a desktop icon to click, or fully automated? I am a designer, not a coder, so I would need help with that.
Thank you for your input!

Hello, do any modifier keys work, like Optio/alt?
Could you have Firmware password protection in Mac OS X ...
http://support.apple.com/kb/HT1352
It would block usage of all the startup keys, like C, N, T, D, CMD+s, CMD+Option+p+r, CMD +v, Option, and Shift, as well as booting from anything but the Hard Drive.
Force Removing Password Protection
1) Add or remove DIMMs to change the total amount of RAM in the computer.
2) Then, the PRAM must be reset 3 times. (Command + Option + P + R).

Need help with Set-ADUser command
I need a little help with the following command. Im new to PS and I have found this command but it is only one user at a time. I need to be able to update ALL users in AD.
My goal is this. Someone before me set all Users Home numbers to 1234567899 and I need to remove that and leave it blank. The command below allows me to do that but only one user at a time by entering their SAMID.
Is there a way to do this for everyone in AD ?
Set-AdUser –Identity SAMID –HomePhone $NULLYeah sure -
Get-Aduser -filter * -properties SamaccountName | Select SamAccountName | % {Set-Aduser -identity $_.SamaccountName -HomePhone $null} -
I need help starting a Terminal command at start-up to help silence CPU fan
I have a 24" iMac (Early 2009) and the CPU fan runs at full RPMs - NOTE: it is a refurbished model. I think that the person who did the refurbishing either messed up the CPU Temp Sensor or something, because the CPU temps are fine and the fan kicks on right after start-up chime.
Anyways, I have found a terminal command (see below) that, when used in conjunction with smcFanControl, will force my CPU fan to run at 1200 RPM. I need a way to either auto-launch this Terminal Command at start-up, or an easier way to launch it because having to type it out in Terminal every boot and reset is getting old.
Terminal Command:
/Applications/smcFanControl.app/Contents/Resources/smc -k F2Mx -w 3cf0
Any help would be greatly appreciated!You shell script should look something like this:
#!/bin/bash
your command line
Construct this in your favorite text editor and save as plain text, not .rtf. Call the file anything you want, but here I'll call it slowfan.
In terminal type,
chmod +x /path/to/slowfan
where /path/to/slowfan is the path to the slowfan file. You could drag the file into the terminal after typing the chmod +x followed by a space. This step is only to mark the text file (script) as executable.
Now you can run Platypus and set up a simple app with admin privleges. Then test the app. If it works you can then add it to your login items.
If you decide to use applescript (do shell script descibed earlier) then you could just use the full pathname to whereever you saved the script and save that as a applescript application. Again test it and then add to your login items. I would bother adding an alias to .bash_profile. That just adds to the complextity.
As you can see, with Platypus you only have the single app it creates to deal with. The script is enclosed in the generated app bundle for easy updating if necessary later on. With the applescript method you will need to keep track of two spearate files; the applescript and the shell script. Actually three, the app too. -
Need help with runtime exe command
Does anybody know how to get the command with double quotes to work with runtime exe?
String cmd = s+" "+fileName;
fin = new BufferedReader(new InputStreamReader(Runtime.getRuntime().exe(cmd).getInputStream()));
if my s is 'grep -i RTU', the fin would have correct value.
but if my s is 'grep -i "RTU"', the fin doesn't have anything (nothing return from exe(cmd) ).
I tried printing out the cmd, it looks fine ( grep -i "RTU" filename ).
Even when I copy the print of cmd and execute it on unix prompt, it return correct value too.
I also tried excaping double qoutes with backslash. Still doesn't work.
Thank you so much in advanceI tried with the exec(String[]) instead of
exec(String).
Still doesn't work.
I'm using Java 2 SDK, Standard Edition Version
1.3.1_02I am afraid I can't help. I can't duplicate your problem - I have no difficulty passing arguments with or without quotation marks using JDK 1.3. I just wrote a test to be sure, and it worked fine. -
Need help with calc all command..
Hi All,
I have a situation where I need some of the members in accounts dim not be aggregated but some to be aggregated..
so i used.............. calc all except mbr(mbmr_name)
but still i see that the values for this member roll up
can any one help me this
thanks in advanceWith knowing all the details, I would suggest maybe creating an alternate hierarchy to provide you another look at aggregate data minus the accounts you are not wanting to aggregate. Just a thought, there are several ways to work this issue......but this is the first I would suggest looking into. If it gets more complicated, then I would explore creating calc script logic utilizing UDA's. Hope this helps.

I need help with the following commands
I had to reformat my Imac. At first I didn´t knew how to do it... so I google for some info and I found this:
start iMac while holding down the CMD+S for the computer to boot into single user mode.
Then:
Type: /sbin/mount -uw / ENTER
Type: rm /var/db/.applesetupdone ENTER
Type: rm -R /Users/* ENTER
Type: shutdown -h now ENTER
the iMac is turned off and is like new.
After I did this nothing happend.... So I called the Technical Service and they explained me very well how to reformat my iMac.
start iMac while holding down alt
Then:
Recovery HD > Disk Utility
Then:
Select Macintosh HD and Erase ...
After doing this... I reinstalled Lion from the internet.
My questions are:
Does the introduction of the commands (/sbin/mount -uw / ENTER, rm /var/db/.applesetupdone ENTER, etc...) may have caused a problem??
If so.. reformat the imac as the Technical Service explained me would have solved??
Thanks a lotYes all solved :-(

New to automator, need help with a pause command
OK, here's what I am trying to do. Open an shn (compressed audio) file with Shorten to decompress to WAV, then open the WAV with iTunes and convert to AAC.
I am unable to set a default folder for output from Shorten, so my current plan is to select all the files, doubleclick and set a desktop folder for the WAV output. I made a folder action for that destination to automatically convert to AAC with iTunes and delete the source files. That folder works fine if I drop all WAV files in, but when they get sent one at a time from Shorten, then only a few of the files get routed to iTunes and the rest stay in the folder unconverted.
I have tried to use "ask for confirmation" which did not work, neither did "wait for user action". I can't use "pause" because each job will be different so I cannot predict how long it will take.
This is my first attempt at Automator and I think I've done pretty well so far (setting the folder action took quite a while to figure out). Any advice would be appreciated.Just a quick response, but...
I would try making a workflow that just takes the desktop, gets it's contents, filters them for WAV files, then does your iTunes-thing. It's not as easy as just having a folder action, but it should work correctly. Folder actions tend not to work as well when you aren't actually dropping items onto them. They're kind of glitchy in my opinion. -
Can't seem to sync my phone with iCal because I get a message that says:No writable calendar. I tried the suggestions I found in Help including a Terminal command to no avail.
I can only suggest you now need to somehow link your mobile to sync with the new calendar 'On my Mac'.
I have a work Blackberry whose calendar I sync with an iCal calendar 'On my Mac' using a usb lead and the Blackberry Desktop Manager for Mac. This free piece of software from Blackberry, automatically starts up as soon as I connect the usb to the iMac and it then prompts me to select which calendar 'On the iMac', which is writable, that I want my Blackberry to sync to. -
Need help with complex column creation command
Hello, all
I need help with a complex column creation command and SQL anywhere help is not sufficient for it.
Here is the situation:
I need to write a generic DDL "alter table" command, which can add/modify columns without knowing in advance if they already exist in the destination table.
Is there a command, which looks like:
alter table "table1" add (on existing modify) column1 <datatype> <default> ?
Thank you,
ArcadyHi.
I don't think this is supported in alter table command. But you can code that inside an if statement which queries systables & syscolumns. Your code should be something like that:
if (select count(*) from sysobjects, syscolumns where sysobjects.id = syscolumns.id and sysobjects.name = 'some_table' and syscolumns.name = 'some_column') < 1
begin
alter table some_table add some_column numeric(12) not null
end
This is an example..

Hello, I need help with my macbook pro.
It looks like I cannot install anything anymore. Everytime I try to install a new software, I simply get stuck during the installation type process. I put in my password, it does accept it, but it does not go any further.
I tried to reset the password, put no password, repair the permissions, the disk but nothing will do. I nearly got stuck with the log in screen but finally succeeded in disabling it.
So I thought I might try to create a new account but I cannot click the lock to make changes. It simply refuses to react.
I am now thinking about using the migration assistant to save all my settings, data and so fourth, but again I get stuck when I have to type in my password. It accepts it but nothing happens...
I guess it has something to do with the authorization process, but can't find anything on the internet about it... Can you help me out?
I am running Lion 10.7.3.
Regards,
Nicolas.
(I apologize if any grammatical/structural mistakes were to be found, english is not my mother-tongue. )You probably won't like this suggestion, but I suggest you reinstall Lion.
First, backup your system. Next, reboot your system, press/hold the COMMAND-R keys to boot into the Recovery HD. Select 'Reinstall Mac OS X'. If you purchased Lion as an upgrade to Snow Leopard, the reinstall process will install Lion 10.7.3. If your system came preinstalled with Lion, you might still get Lion 10.7.2. Both installs are a total install of the OS. None of your apps or data will be impacted. Just the OS. -
Need help with calculator project for an assignment...
Hi all, I please need help with my calculator project that I have to do for an assignment.
Here is the project's specifications that I need to do"
"""Create a console calculator applicaion that:
* Takes one command line argument: your name and surname. When the
program starts, display the date and time with a welcome message for the
user.
* Display all the available options to the user. Your calculator must include
the arithmetic operations as well as at least five scientific operations of the
Math class.
-Your program must also have the ability to round a number and
truncate it.
-When you multiply by 2, you should not use the '*' operator to perform the
operation.
-Your program must also be able to reverse the sign of a number.
* Include sufficient error checking in your program to ensure that the user
only enters valid input. Make use of the String; Character, and other
wrapper classes to help you.
* Your program must be able to do conversions between decimal, octal and
hex numbers.
* Make use of a menu. You should give the user the option to end the
program when entering a certain option.
* When the program exits, display a message for the user, stating the
current time, and calculate and display how long the user used your
program.
* Make use of helper classes where possible.
* Use the SDK to run your program."""
When the program starts, it asks the user for his/her name and surname. I got the program to ask the user again and again for his/her name and surname
when he/she doesn't insert anything or just press 'enter', but if the user enters a number for the name and surname part, the program continues.
Now my question is this: How can I restrict the user to only enter 'letters' (and spaces of course) but allow NO numbers for his/her surname??

What you could do is checking the input string for numbers. If it contains numbers, just reprompt for the Name.
AND you might want to ask yourself why the heck a calculator needs to know the users Name. -
Need help with Berkeley XML DB Performance
We need help with maximizing performance of our use of Berkeley XML DB. I am filling most of the 29 part question as listed by Oracle's BDB team.
Berkeley DB XML Performance Questionnaire
1. Describe the Performance area that you are measuring? What is the
current performance? What are your performance goals you hope to
achieve?
We are measuring the performance while loading a document during
web application startup. It is currently taking 10-12 seconds when
only one user is on the system. We are trying to do some testing to
get the load time when several users are on the system.
We would like the load time to be 5 seconds or less.
2. What Berkeley DB XML Version? Any optional configuration flags
specified? Are you running with any special patches? Please specify?
dbxml 2.4.13. No special patches.
3. What Berkeley DB Version? Any optional configuration flags
specified? Are you running with any special patches? Please Specify.
bdb 4.6.21. No special patches.
4. Processor name, speed and chipset?
Intel Xeon CPU 5150 2.66GHz
5. Operating System and Version?
Red Hat Enterprise Linux Relase 4 Update 6
6. Disk Drive Type and speed?
Don't have that information
7. File System Type? (such as EXT2, NTFS, Reiser)
EXT3
8. Physical Memory Available?
4GB
9. Are you using Replication (HA) with Berkeley DB XML? If so, please
describe the network you are using, and the number of Replica’s.
No
10. Are you using a Remote Filesystem (NFS) ? If so, for which
Berkeley DB XML/DB files?
No
11. What type of mutexes do you have configured? Did you specify
–with-mutex=? Specify what you find inn your config.log, search
for db_cv_mutex?
None. Did not specify -with-mutex during bdb compilation
12. Which API are you using (C++, Java, Perl, PHP, Python, other) ?
Which compiler and version?
Java 1.5
13. If you are using an Application Server or Web Server, please
provide the name and version?
Oracle Appication Server 10.1.3.4.0
14. Please provide your exact Environment Configuration Flags (include
anything specified in you DB_CONFIG file)
Default.
15. Please provide your Container Configuration Flags?
final EnvironmentConfig envConf = new EnvironmentConfig();
envConf.setAllowCreate(true); // If the environment does not
// exist, create it.
envConf.setInitializeCache(true); // Turn on the shared memory
// region.
envConf.setInitializeLocking(true); // Turn on the locking subsystem.
envConf.setInitializeLogging(true); // Turn on the logging subsystem.
envConf.setTransactional(true); // Turn on the transactional
// subsystem.
envConf.setLockDetectMode(LockDetectMode.MINWRITE);
envConf.setThreaded(true);
envConf.setErrorStream(System.err);
envConf.setCacheSize(1024*1024*64);
envConf.setMaxLockers(2000);
envConf.setMaxLocks(2000);
envConf.setMaxLockObjects(2000);
envConf.setTxnMaxActive(200);
envConf.setTxnWriteNoSync(true);
envConf.setMaxMutexes(40000);
16. How many XML Containers do you have? For each one please specify:
One.
1. The Container Configuration Flags
XmlContainerConfig xmlContainerConfig = new XmlContainerConfig();
xmlContainerConfig.setTransactional(true);
xmlContainerConfig.setIndexNodes(true);
xmlContainerConfig.setReadUncommitted(true);
2. How many documents?
Everytime the user logs in, the current xml document is loaded from
a oracle database table and put it in the Berkeley XML DB.
The documents get deleted from XML DB when the Oracle application
server container is stopped.
The number of documents should start with zero initially and it
will grow with every login.
3. What type (node or wholedoc)?
Node
4. Please indicate the minimum, maximum and average size of
documents?
The minimum is about 2MB and the maximum could 20MB. The average
mostly about 5MB.
5. Are you using document data? If so please describe how?
We are using document data only to save changes made
to the application data in a web application. The final save goes
to the relational database. Berkeley XML DB is just used to store
temporary data since going to the relational database for each change
will cause severe performance issues.
17. Please describe the shape of one of your typical documents? Please
do this by sending us a skeleton XML document.
Due to the sensitive nature of the data, I can provide XML schema instead.
18. What is the rate of document insertion/update required or
expected? Are you doing partial node updates (via XmlModify) or
replacing the document?
The document is inserted during user login. Any change made to the application
data grid or other data components gets saved in Berkeley DB. We also have
an automatic save every two minutes. The final save from the application
gets saved in a relational database.
19. What is the query rate required/expected?
Users will not be entering data rapidly. There will be lot of think time
before the users enter/modify data in the web application. This is a pilot
project but when we go live with this application, we will expect 25 users
at the same time.
20. XQuery -- supply some sample queries
1. Please provide the Query Plan
2. Are you using DBXML_INDEX_NODES?
Yes.
3. Display the indices you have defined for the specific query.
XmlIndexSpecification spec = container.getIndexSpecification();
// ids
spec.addIndex("", "id", XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
spec.addIndex("", "idref", XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
// index to cover AttributeValue/Description
spec.addIndex("", "Description", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ELEMENT | XmlIndexSpecification.KEY_SUBSTRING, XmlValue.STRING);
// cover AttributeValue/@value
spec.addIndex("", "value", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
// item attribute values
spec.addIndex("", "type", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
// default index
spec.addDefaultIndex(XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ELEMENT | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
spec.addDefaultIndex(XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
// save the spec to the container
XmlUpdateContext uc = xmlManager.createUpdateContext();
container.setIndexSpecification(spec, uc);
4. If this is a large query, please consider sending a smaller
query (and query plan) that demonstrates the problem.
21. Are you running with Transactions? If so please provide any
transactions flags you specify with any API calls.
Yes. READ_UNCOMMITED in some and READ_COMMITTED in other transactions.
22. If your application is transactional, are your log files stored on
the same disk as your containers/databases?
Yes.
23. Do you use AUTO_COMMIT?
No.
24. Please list any non-transactional operations performed?
No.
25. How many threads of control are running? How many threads in read
only mode? How many threads are updating?
We use Berkeley XML DB within the context of a struts web application.
Each user logged into the web application will be running a bdb transactoin
within the context of a struts action thread.
26. Please include a paragraph describing the performance measurements
you have made. Please specifically list any Berkeley DB operations
where the performance is currently insufficient.
We are clocking 10-12 seconds of loading a document from dbd when
five users are on the system.
getContainer().getDocument(documentName);
27. What performance level do you hope to achieve?
We would like to get less than 5 seconds when 25 users are on the system.
28. Please send us the output of the following db_stat utility commands
after your application has been running under "normal" load for some
period of time:
% db_stat -h database environment -c
% db_stat -h database environment -l
% db_stat -h database environment -m
% db_stat -h database environment -r
% db_stat -h database environment -t
(These commands require the db_stat utility access a shared database
environment. If your application has a private environment, please
remove the DB_PRIVATE flag used when the environment is created, so
you can obtain these measurements. If removing the DB_PRIVATE flag
is not possible, let us know and we can discuss alternatives with
you.)
If your application has periods of "good" and "bad" performance,
please run the above list of commands several times, during both
good and bad periods, and additionally specify the -Z flags (so
the output of each command isn't cumulative).
When possible, please run basic system performance reporting tools
during the time you are measuring the application's performance.
For example, on UNIX systems, the vmstat and iostat utilities are
good choices.
Will give this information soon.
29. Are there any other significant applications running on this
system? Are you using Berkeley DB outside of Berkeley DB XML?
Please describe the application?
No to the first two questions.
The web application is an online review of test questions. The users
login and then review the items one by one. The relational database
holds the data in xml. During application load, the application
retrieves the xml and then saves it to bdb. While the user
is making changes to the data in the application, it writes those
changes to bdb. Finally when the user hits the SAVE button, the data
gets saved to the relational database. We also have an automatic save
every two minues, which saves bdb xml data and saves it to relational
database.
Thanks,
Madhav
[email protected]Could it be that you simply do not have set up indexes to support your query? If so, you could do some basic testing using the dbxml shell:
milu@colinux:~/xpg > dbxml -h ~/dbenv
Joined existing environment
dbxml> setverbose 7 2
dbxml> open tv.dbxml
dbxml> listIndexes
dbxml> query { collection()[//@date-tip]/*[@chID = ('ard','zdf')] (: example :) }
dbxml> queryplan { collection()[//@date-tip]/*[@chID = ('ard','zdf')] (: example :) }Verbosity will make the engine display some (rather cryptic) information on index usage. I can't remember where the output is explained; my feeling is that "V(...)" means the index is being used (which is good), but that observation may not be accurate. Note that some details in the setVerbose command could differ, as I'm using 2.4.16 while you're using 2.4.13.
Also, take a look at the query plan. You can post it here and some people will be able to diagnose it.

Need help with a simple process with FTP Adapter and File Adapter
I am trying out a simple BPEL process that gets a file in opaque mode from a FTP server using a FTP adapter and writes it to the local file system using a File Adapter. However, the file written is always empty (zero bytes). I then tried out the FTPDebatching sample using the same FTP server JNDI name and this work fine surprisingly. I also verified by looking at the FTP server logs that my process actually does hit the FTP server and seems to list the files based on the filtering condition - but it does not issue any GET or RETR commands to actually get the files. I am suspecting that the problem could be in the Receive, Assign or Invoke activities, but I am not able identify what it is.
I can provide additional info such as the contents of my bpel and wsdl files if needed.
Would appreciate if someone can help me with this at the earliest.
Thanks

Need Help with a Flash Web Project
Hello, everyone. I am trying to use Flash to make a two-step
system. I want the flash document to, first, allow a person to
upload multiple image files and then, second, for the flash
document be able to create a slideshow with the uploaded images and
fade in and out from each image until the slideshow is over. I want
it to be where the flash document creates its own slideshow with
the images that are uploaded in the first step that I mentioned. I
want it to do it completely on its own so I need to know how to
give it the proper AI so that it can do this task.
So, are there any tips that anyone has on how to do this? Can
anyone tell me exactly how to do this? I really need help with this
for my new website project. Thanks in advance, everyone!The problem with the text not appearing at all has to do with you setting the alpha of the movieclip to 0%. Not within the movieclip, but the movieclip itself. The same for the xray graphic, except you have that as a graphic symbol rather than a movieclip. To have that play while inhabiting one frame you'll need to change it to a movieclip symbol.
To get the text to play after the blinds (just a minor critique, I'd speed up the blinds), you will want to add some code in the frame where you added the stop in the blinds animation. You will also need to assign instance names for the text movieclips in the properties panel, as well as place a stop(); in their first frames (inside).
Let's say you name them upperText and lowerText. Then the code you'd add at the end of the blinds animation (in the stop frame) would be...
_parent.upperText.play();
_parent.lowerText.play();
The "_parent" portion of that is used to target the timeline that is containing the item making the command, basically meaning it's the guy inside the blinds telling the guy outside the blinds to do something.
You'll probably want to add stops to the ends of the text animations as well.
If you want to have the first text trigger the second text, then you'd take that second line above and place it in the last frame of the first text animation instead of the blinds animation.
Note, on occasion, undeterminably, that code above doesn't work for some odd reason... the animation plays to the next frame and stops... so if you run into that, just put a play(); in the second frame to help push it along.
PS GotoandPlay would actually be gotoAndPlay, and for the code above you could substitute play(); with gotoAndPlay(2);
