Question about using uuid in kernel boot argument

Have my root partition on sda3 with uuid-> 81222792-bd9f-47d6-8d28-b4b59d93cbac
Grub is able to boot if I use either:
root=/dev/sda3
or
root=/dev/disk/by-uuid/81222792-bd9f-47d6-8d28-b4b59d93cbac
But not by using:
root=UUID=81222792-bd9f-47d6-8d28-b4b59d93cbac
Do I need to do some steps if I want to use root=UUID=xxx syntax in the root partition of the grub/grub2 bootloader?

Found this link on Google http://en.gentoo-wiki.com/wiki/Initramfs. In short it tells that you need some support in the initrd image. Since both kernel26.img and kernel26-fallback.img failed to boot using root=UUID=xxxx syntax, then I guess that support is not included by default on our images.
Since working/hacking the initrd/mkinitcio is atm too much for me to handle, I hope someone with more experience can give me some light in the issue.

I have a question about using multiple ipads in our school. Each of our teachers have a iPad and AppleTV in their classroom. The issue is, with our classrooms so close in proximity to one another, is there a way to pair teacher #1 iPad to its AppleTV without effecting/projecting onto the adjacent teachers #2 classroom AppleTV?

Not as such.
Give the AppleTV units unique names and also enable Airplay password in settings with unique passwords for each teacher.

Hi, I have quick question about use of USEBEAN tag in SP2. When I specify a scope of SESSION for the java bean, it does not keep the values that I set for variable in the bean persistent.Thanks,Sonny

Make sure that your bean is implementing the serializable interface and that
you are accessing the bean from the session with the same name.

Question about using new battery in old Powerbook

I have a pre-intel Powerbook G4, and the battery is pretty much toast (lasts about 15 minutes now). I have ordered a new battery for it, and I have this question about using it:
Am I smarter to keep the new strong battery out of the PB most days (as I usually work with it plugged in at home) and just pop it in when I know I will be out surfing on batteries? Or is it just as good living in my laptop 24/7 and only occasionally being called upon to do its job?
Current bad Battery Information below:
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 1144
Remaining Capacity (mAh): 1115
Amperage (mA): 0
Voltage (mV): 12387
Cycle Count: 281
thanks folks, Shereen

Hi, Shereen. Every Powerbook battery wants to be used — drained and then recharged — at least every couple of weeks. If you've always used your Powerbook on AC power nearly all the time, and not followed that pattern of discharging and recharging the battery every week or two, it's possible that your use habits have shortened the lifespan and prematurely diminished the capacity of your old battery. Of course it's also possible that your battery is merely old, as a battery's capacity also diminishes with age regardless of how it's used. You didn't say how old the battery is in years, so this may or may not be an issue. I mention it only because it can be an issue.
For general information on handling a battery for the longest possible lifespan, see this article. My advice on the basis of that article and long experience reading these forums is that it would be OK to do as you propose, but I doubt that you'd derive any significant benefit from it. You would still want to be sure of putting the new battery through a charge/discharge cycle every week or two, even if you didn't have a reason to use the Powerbook away from home or your desk, because sitting unused outside the computer is just as bad for a battery as sitting unused inside it. And you should never remove the battery from your computer when it's completely or almost completely discharged and let it sit that way any longer than a day or two.

Question about using TVARV in an ABAP program

Hello gurus, Im sorry about the silly question.
I have a question about using TVARV in an ABAP program.
A program is presenting a problem and I think that in this code:
SELECT SIGN OPTI LOW HIGH
FROM TVARV
INTO TABLE R_1_163431035_VELOCIDADE
WHERE NAME = '1_163431035_VELOCIDADE'
AND    TYPE = 'S'.
IF ZMM001-VELOCIDADE_B   IN R_1_163431035_VELOCIDADE AND
      ZOPERADORAS-OPERADORA = 'ABCD' AND
      ZMM001-MATERIAL       IN R_1_163431035_PRODUTO.
ELSE.
ENDIF.
What happens is that the value "ZMM001-SPEED" B not exist in "R1_163431035_VELOCIDADE" but the program executes commands under the IF and not under the ELSE, as I imagine it would work. Is this correct ?
I am new to ABAP programming, but I have a lot of XP in other programming languages and this makes no sense to me.
Anyone know where I can find some documentation of the use of "TVARV" in ABAP programs?
I search the Internet if other programmers use TVARV this way, but found nothing, which leads me to think that was a quick and dirty solution that used here.
If this is a bad way to program, what would be the best way?
Regards
Ronaldo.

Hi Ronaldo,
But in this case, the range is not empty, there are 17 records, in this way.:
For the column "SING" all values are "E"
It means that the result is false if ZMM001-VELOCIDADE_B has the same value as one of the 17 records (E = exclude).
For instance, if it has value 'C' and one of 17 records matches C, then the result is false.
The "IF" with "IN" using "TVARV" as used in the program of the post above has the same behavior of a selection screen?
Yes, the same behavior as the selection criterion to be exact. You can press the help key in the complex selection dialog for more info.
I know it's a silly and very basic question, but other language that I used, only the SQL has the "IN" operator, but I think they work in different ways, so I would like to understand how it works in ABAP.
Not silly ;-). Yes they work differently.

Question about using Macbook in Vietnam.

I have a question about using Macbook in Vietnam. I bought my mac here in the US, and I'm going to visit Vietnam, but I'm wondering if I can plug in the power directly into the wall or I have to need any convert power modem for my mac. The only thing I know that Vietnam use 220V so, can anyone help me?

You may need a plug adaptor, but you don't need a power converter.

Question about Using PAPI Web Service in PowerBuilder 9

Hi, all.
I Have a simple question about using papiws in power builder 9.
In pb9, I created a new Web Service Proxy Wizard and I input a url for papiws(ex. http://seraphpernote:7001/papiws/PapiWebService) and click next.
But I couldn't get any Service List.
In Eclipse, I used this url for using papiws well.
Does anybody know about this case??
help me plz.

IIRC you must activate PAPI-WS for the engine. In Studio you do it by right-clicking on the project, then "engine preferences". In enterprise/standalone you must activate PAPI-WS in the Admin Center.

Question about using 10g/11g and APEX ...

Hi,
I just recently learned of Oracle's APEX and have a few questions about using it.
Can I use APEX with express, standard, and enterprise editions of 10g and 11g?
Are all of these free to use?

You might want to read about APEX rather than jumping into questions that are reasonably well documented. Info at http://www.oracle.com/technology/products/database/application_express/index.html
Your specific questions:
1) Apex is a package that can be installed into any properly licensed database.
2) The price for the production license of the database varies by edition.
The price for Express Edition is $0 for use in production. Part of the cost for that edition is 'no Oracle Support based support, no patches, data volume limitation, etc.'

Question about using Runtime.getRuntime();

hi all
i have a question about using Runtime.getRuntime(). if i use this to get a runtime reference to run an external program, is it considered as starting a new thread inside the thread that starts it?
is it safe to do it in the Session EJB? if not, what can you recommand to do it? thanks

hi all
i have a question about using Runtime.getRuntime().
if i use this to get a runtime reference to run an
external program, is it considered as starting a new
thread inside the thread that starts it? No. Starting a process, starts a process. Threads have nothing to do with it.
is it safe to do it in the Session EJB? if not, what
can you recommand to do it? thanksSo what? Run another process? If you want to run another process in java then your choices are to use Runtime.exec() or use JNI. And using JNI will probably end up doing exactly the same thing as Runtime.exec().
"Safe" is harder. Typically to correctly use Runtime.exec() you must use threads. And as noted threads ideally should not be used. You can use them but if you do you had better understand why they didn't want you using them in the first place. You had also better be sure that you really want to wait for it to complete.
Other than that Runtime.exec() is safe because it can't crash the VM like other interfaces can (like JNI.)

Questions about using a PDF form online

I have a client who wants to create an online version of a PDF form that they are currently using. I am currently trying to explain to them that this would be best done as an HTML web form, but I may not win this argument. I have only used PDFs for printed forms (either hand-written or using form fields) so I am not familiar with any problems that converting the form for use online would entail.
When the 'Submit' button is pressed on the form, is there a way to redirect to another web page after the data is submitted? (i.e. does the PDF have access to it's outer 'environment'?)
Are there any security issues submitting data using the PDF form as opposed to using a standard web form? (There may be sensitive data being submitted)
I'm not sure how they plan to handle the data that is submitted, but there are several options in the submitForm parameters - I am assuming that using the HTML option would submit the data in the same format as a web form would. Am I correct here?
Can the PDF be prevented from being downloaded or printed? This form should only be used to submit data to their server, not as a printed form.
Are there any other 'gotchas' that I need to look out for? Does anyone have a recommendation for a site which contains any tutorials or guidelines for using PDF forms online?

Thanks for the information.
Yes, I agree that there is less reason for it to be a PDF form (Actually, no real reason other than the original form already exists in PDF), but I am unfortunately in the position that my input in this project is not necessarily being considered (my company is following direct -and inconsistent- directions from the client, and I have no contact with the client to ask questions about what their actual needs are). I have been told to give the client the 'Tomato' that they are asking for, even though they are describing an 'Apple'.
The reason this form is not meant to be printed is that we have replaced the 'Signature' fields from the original form with checkboxes that the user must check to confirm they have 'signed' the document. If they are to print/fax/whatever the document, they should use the original form, not this one. And I am still trying to explain to them that this would be better served with an HTML web form, but I fear I am losing that battle.
I have brought up the fact that it is not 100% guaranteed that Acrobat will be available in the browser, although I can only guess that it is less than likely that anyone will not have some sort of PDF viewer available to their browser.
I will also mention that issues may arise if the file is not submitted from within the browser.

Question about using iMac 2011 as a monitor

hi ,, i have imac 2011 21'5
can i use as a monitor to play xbox 360 on it using mini displayport to hdmi cable ??
if no then is there way else i can play xbox on my imac screen

Frank:
Thanks so much for responding! One question about your post. When you say that the Mac Mini cannot boot in OS 9, does that mean that if I wanted it to hold Filemaker Pro 4 files (which runs on OS 9), that it cannot do this? We would not be running Filemaker on the Mini, just storing the files. We would run Filemaker off of our desktop computers. Sorry, I don't know a ton about computers, so sometimes I need clarification about the terms that people use.-Rob

Question about using a SATA drive through an Epress34 card???

I have a basic question about OSX and how it treats a SATA drive hung from an Express34 SATA card. So OSX just treats any drive as a mounted drive as far as I know bbut what about when booting...
If, at boot up, I use the 'cmd C' option to select an external SATA dirve hanging off of an Express34 SATA card, will OSX see that drive as if it just were the internal drive in the MBP or is there some inherant difference between the real internal drive and any other SATA drive?
I guess the question is... does the cmd C option really just tell the OS to treat this drive as though it were the interal drive and boot from it (assuming the drive is bootable of course) or is ot doing something else.
If that is the case, why can't I use an external drive and install BootCamp on it, assumiong that I booted from this drive?
Is there a difference between an external SATA drive from an Express34 card and an external firewire drive?
TIA,
Peter

Question about using mac mini as a server

I run a small non-profit agency. Our server (A Mac G4 from about 4 years ago) recently died a somewhat painful death, and we need to get a new one. We're trying to be thrifty, but i don't want to get something that won't meet our needs. Our server needs are very basic. No more than 8 people will ever access the server at the same time, and generally it will be 2-4 people at once. We keep Word and Excel docs on it (It used to host our database, but we will have a separate server for our new database). Do you think a Mac Mini with the following specs would meet our needs:
80 GB Hard Drive
1 GB RAM
1.42 GHz PowerPC G4
