Some question about windows 7 and mini laptop

hi
i glad that i found this forum, i have the mini HP laptop 110 and i have some question
(i have intel atom 1.66 , 2G memory and windows 7 starter)
1. if i'll instal the windows 7 pro - is my performance will be smaller ?
2. what is the most light anti-virus that recommended for this mini laptop ?
3. what is the most light browser that recommended for this mini laptop ?
thank's in advance

Windows 7 is Windows 7 as far as the resources it consumes. So feel free to upgrade to 7 Pro and your performance should not take a hit. For light antivirus I recommend Avira. It is what I have on my own netbook. Lastly a good light browser is Opera.

New Mac Pro - some questions about setup and RAM

After debating between iMac and Mac Pro, I decided on a refurb SINGLE 2.8 quad-core Mac Pro.
Somewhere in these discussions (can't find it now) I thought I saw recommendations to zero out the hard drive and re-install the system when it arrives. Is this necessary?
Also, I plan to use the single processor savings to buy RAM. When I go to the Crucial site, they have a choice of RAM for 4-core or 8-core. Mine is only 4-core, but would I choose the 8-core option to get the correct RAM for 2008 models?
In general, when it comes to buying and installing RAM, should I follow the 8-core directions? Will having a single processor change anything to do with upgrades or expansion?
Thanks. Hope I didn't ask too much in one post.

Somewhere in these discussions (can't find it now) I thought I saw recommendations to zero out the hard drive and re-install the system when it arrives. Is this necessary?
No, that really isn't necessary. If you were prepping a new bare drive that had never been used or you were installing OS X on a drive that had once been used for Windows, then zeroing the drive is quite appropriate.
All the Mac Pros use the same type of RAM. The Late 2008 models use the faster PC2-6400 800 MHz RAM, but the other specs are the same - ECC, Fully buffered, heat sink. The RAM and installation is the same regardless of cores.
RAM should be installed minimally in matched pairs, optimally in matched quads. The following illustrations show how it should be installed:

Somes questions about WFQ and Per-Hop Behavior

Hi !
I'm currently self studding for my CCNP ONT certification Exam.
I read the official certification guide for this exam from Cisco Press. But, some point are still confuse for me :
1- Why WRED is most deploy on cores devices then all devices in Enterprise Network ? (The author saied :"Because WRED is usually applied to network core router....") And which implementation of congestion management system I should deploy on none core device, because thoses can also experience congestion in some point of the day and tail drop should be avoid also on thoses (distribution and access devices) devices also if I understand correctly ?
2- I understand WRED is an evolution of RED. Is still exist some reason to choose to use RED over WRED ? If WRED is available in device, is the RED is also available ? In my book in the example it say to activate WRED the command is RANDOM-DETECT, what about to activate RED ?
3- I'm confused about "class selector Per-Hop Behavior", if I'm understand correctly, We have 8 sub-classes "class selector Per-Hop Behavior" for each : Default Per-Hop Behavior, Assured Forwarding 1 to 4, and Expedited Forwarding, where the lowest value have higher probability to be drop. The class "class selector Per-Hop Behavior" work in the inverse of there parent where the highest value have higher probability to be drop.
in the exemple (copied from the book) how the preference of dropping is selected :
random-detect dscp-based
random-detect dscp af21 32 40 10
random-detect dscp af22 28 40 10
random-detect dscp af23 24 40 10
random-detect dscp cs2 22 40 10
I'm correctly understand how I should interpret the "random-detect dscp af" in comparaison of each other but, I don't understand where the I should place the "random-detect dscp cs2" with regard to the others.
Thanks a lot in advanced for your help !

Hi,
The main difference betwwen PQ and LLQ is this.
PQ: Exclusively starves other traffic while serving packets in its queue. Infact PQ is so greedy, other traffic may never get serviced as long as there are packets in the PQ.
LLQ: It combines the bandwidth reservation of CBWFQ with PQ.
LLQ uses Policing to ensure that Bandwidth configured for PQ is not exceeded and when exceeded, drops the packets and then service the non-LLQ queues.
Hence LLQ ensures guranteed badnwidth only to the contracted amount.
Eg if a LLQ has 30kbps of bandwidht reserved. This can take a single G.729 call. If a 2nd call comes in, the policer will discard packets and both calls will sound bad. Hence its important to use CAC to limit the number of calls allowed to that configured for LLQ bandwidth, so the policer does not drop packets.
LLQ traffic uses the EF Diffserv PHB.
The EF PHB has 2 components.
1. Queueing to provide low delay, jitter or loss plus a guranteed bandwidth.
2. Policing to prevent EF traffic/LLQ traffic from starving other traffic of bandwidth.
So in summary, PQ will always treat PQ traffic firts and will starve other traffic of bandwidth
LLQ on the other hand will serve LLQ queues to the tune of bandwidth configured for them and then service other queues too.

[newbie question] some question about MBean and notification

Hi,
can i manage an existing java object with OpenMBean? if yes how to connect them ( for ModeMBean it's setManagedResource but for OpenMBean)?
How can i send a notification from a generated ModelMBean ?(should i change my java object to impement NotificationBroadcasterSupport ?)

Hi,
An OpenMBean is just an MBean that has a ModelMBeanInfo, and uses only simple types
as defined by javax.management.openmbean.
You can use OpenMBeans to manage your resource, but if you don't have MXBeans
then you will need to write your OpenMBean by hand. This is not very difficult but
is a bit tedious.
There should be a chapter on OpenMBeans in the JMX tutorial - have a look at it.
http://blogs.sun.com/jmxetc/entry/looking_for_jmx_overview_examples
To send a notification with a RequiredModelMBean just use its sendNotification() method.
http://java.sun.com/j2se/1.5.0/docs/api/javax/management/modelmbean/ModelMBeanNotificationBroadcaster.html#sendNotification(javax.management.Notification)
With a "generated ModelMBean" I don't know - I assume it depends on how and by what
it was generated and whether it is a subclass of javax.management.modelmbean.RequiredModelMBean.
You will need to look at the generated code to figure it out.
Hope this helps,

Some question about flex and facebook, and saving server work!

Hi guys im starting to develop facebook application and im not surre what is the better way to connect my app to facebook.
first option is to pull all the data from facebook through PHP and then send it to the app. or getting the data directly to my app through actionscript.
what is the better option? the first option takes more server work, is that something to consider or its irrelevant to small-medium apps?
another thing , does PHP integrets better whit facebok than actionscript? does the APIs of PHP and ActionScript are the same??
what would u say is better??

I have a Macbook Pro june 2011... I have 8GB ram but I only have 256mb VRAM... I've read some other questions about this and I realized... Why do I not have 560mb of VRAM since I have 8GB of RAM? Is there any way to get more VRAM to play games on steam?

I have a Macbook Pro june 2011... I have 8GB ram but I only have 256mb VRAM...
I've read some other questions about this and I realized... Why do I not have 560mb of VRAM since I have 8GB of RAM?
Is there any way to get more VRAM to play games on steam?
I've learned by reading other topics that I can't upgrade my graphics card on my Macbook Pro because it's soldered into the motherboard or somthing like that, but please tell me if there is any way to get more video ram by chaning some setting or upgrading something else. I'd also like to know why I only have 256MB of VRAM when I have 8GB of RAM, since I have 8GB of RAM I thought I was supposed to have 560mb of VRAM...
So the two questions are...
Is there any way to upgrade my VRAM, so that I can play games on steam?
Why do I only have 256MB VRAM when I have 8GB total RAM?
Other Info:
I have a quad core i7 Processor.
My graphcics card is the AMD Radeon HD 6490M.
I am also trying to play games on my BOOTCAMPed side of my mac, or my Windows 7 Professional side.
THANK YOU SO MUCH IF YOU CAN REPLY,
Dylan

The only two items that a user can change on a MBP are the RAM and HDD (Retinas not included). You have what the unit came with and the only way you will be able to change that is to purchase a MBP with superior graphics
If you are very much into gaming, the I suggest A PC. They are far superior for that type of application to a MBP.
Ciao.

Some questions about the integration between BIEE and EBS

Hi, dear,
I'm a new bie of BIEE. In these days, have a look about BIEE architecture and the BIEE components. In the next project, there are some work about BIEE development based on EBS application. I have some questions about the integration :
1) generally, is the BIEE database and application server decentralized with EBS database and application? Both BIEE 10g and 11g version can be integrated with EBS R12?
2) In BIEE administrator tool, the first step is to create physical tables. if the source appliation is EBS, is it still needed to create the physical tables?
3) if the physical tables creation is needed, how to complete the data transfer from the EBS source tables to BIEE physical tables? which ETL tool is prefer for most developers? warehouse builder or Oracle Data Integration?
4) During data transfer phase, if there are many many large volume data needs to transfer, how to keep the completeness? for example, it needs to transfer 1 million rows from source database to BIEE physical tables, when 50%is completed, the users try to open the BIEE report, can they see the new 50% data on the reports? is there some transaction control in ETL phase?
could anyone give some guide for me? I'm very appreciated if you can also give any other information.
Thanks in advance.

1) generally, is the BIEE database and application server decentralized with EBS database and application? Both BIEE 10g and 11g version can be integrated with EBS R12?You, shud consider OBI Application here which uses OBIEE as a reporting tool with different pre-built modules. Both 10g & 11g comes with different versions of BI apps which supports sources like Siebel CRM, EBS, Peoplesoft, JD Edwards etc..
2) In BIEE administrator tool, the first step is to create physical tables. if the source appliation is EBS, is it still needed to create the physical tables?Its independent of any soure. This is OBIEE modeling to create RPD with all the layers. If you build it from scratch then you will require to create all the layers else if BI Apps is used then you will get pre-built RPD along with other pre-built components.
3) if the physical tables creation is needed, how to complete the data transfer from the EBS source tables to BIEE physical tables? which ETL tool is prefer for most developers? warehouse builder or Oracle Data Integration?BI apps comes with pre-built ETL mapping to use with the tools majorly with Informatica. Only BI Apps 7.9.5.2 comes with ODI but oracle has plans to have only ODI for any further releases.
4) During data transfer phase, if there are many many large volume data needs to transfer, how to keep the completeness? for example, it needs to transfer 1 million rows from source database to BIEE physical tables, when 50%is completed, the users try to open the BIEE report, can they see the new 50% data on the reports? is there some transaction control in ETL phase?User will still see old data because its good to turn on Cache and purge it after every load.

Some questions about javacard 2.1.1 and smartcardio

Hello i have some question about java card 2.1.1 and the smartcardio package.
1.) I want to sign a message with the Signature.ALG_RSA_SHA_PKCS1 algorithm. I use the following code in the applet to sign the message:
final static byte P1_CREATION_MODE = (byte) 0x01;
final static byte INS_SIGN_MODE = (byte) 0x60;
final static byte SmartCard_CLA = (byte) 0xB0;
private void signMessage(APDU apdu) {
        byte[] buffer = apdu.getBuffer();
        byte byteRead = (byte) (apdu.setIncomingAndReceive());
        signature.init(privateKey, Signature.MODE_SIGN);
        short length = signature.sign(buffer, ISO7816.OFFSET_CDATA, byteRead, buffer, (short) 0);
        apdu.setOutgoingLength((short) length);
        apdu.sendBytesLong(buffer, (short) ISO7816.OFFSET_CDATA, (short) length);
        apdu.setOutgoing();
    }On the host side I use the following code to connect to the card and to send the sign apdu:
if (TerminalFactory.getDefault().terminals().list().size() == 0) {
            LOGGER.log(Level.SEVERE, "No reader present");
            throw new NoSuchCardReader();
        /* Select the first terminal*/
        CardTerminal terminal = TerminalFactory.getDefault().terminals().list().get(0);
        /* Is a card present? */
        if (!terminal.isCardPresent()) {
            LOGGER.log(Level.SEVERE, "No Card present!");
            throw new NoSuchCard();
        /* Set the card protocol */
     Card card = terminal.connect("*");
        ATR atr = card.getATR();
        LOGGER.fine(getHexString(atr.getBytes()));
        LOGGER.fine(getHexString(atr.getHistoricalBytes()));
        CardChannel channel = card.getBasicChannel();
        CommandAPDU cmd = new CommandAPDU((byte) 0xb0, (byte) 0x60, (byte) 0x01, (byte) 0x00, new String("datadatdatadata").getBytes(), (byte) 0x40);
     ResponseAPDU response = channel.transmit(cmd);
        card.disconnect(false);But this does not work and i got the following error
javax.smartcardio.CardException: sun.security.smartcardio.PCSCException: Unknown error 0x8010002f

        ... 3 more2.) 3Des encryption
I want to use the 3Des algorithm to encrypt my data. I use
keyDES = (DESKey) KeyBuilder.buildKey(KeyBuilder.TYPE_DES,
                    KeyBuilder.LENGTH_DES3_2KEY, false);
cipherDES = Cipher.getInstance(Cipher.ALG_DES_CBC_ISO9797_M2, false);But i do not know what is the aquivalent on the host side??
3.) Another problem is that i am not able to send the modulus of a public key from the host applikation to the smard card
new CommandAPDU((byte) 0xb0, (byte) 0x20, (byte) 0x01, (byte) 0x00, modulus.toByteArray()); // create the apdu
// the method in the applet
private void setServerKeyMod(APDU apdu) {
        byte[] buffer = apdu.getBuffer();
        try {
            byte byteRead = (byte) (apdu.setIncomingAndReceive());
            short off = ISO7816.OFFSET_CDATA;
            // strip of any integer padding
            if (buffer[off] == 0) {
                off++;
                byteRead--;
            publicKeyServer.setModulus(buffer, off, byteRead);
        } catch (APDUException ex) {
            ISOException.throwIt((short) (SW_APDU_EXCEPTION + ex.getReason()));
    }The error code is 6700
4.) My last problem ist, that i am not able to use a value bigger than 0x7F as the ne field in the apducommand, because i get the following error
CommandAPDU((byte) 0xb0, (byte) 0x60, (byte) 0x01, (byte) 0x00, data, (byte) 0xff);
java.lang.IllegalArgumentException: ne must not be negative
        at javax.smartcardio.CommandAPDU.<init>(CommandAPDU.java:371)
        at javax.smartcardio.CommandAPDU.<init>(CommandAPDU.java:252)I thought that it this should be possible in order to use all the bytes of the response apdu.
If you need more code to help please let me know.
Cheers

2) What is PKCS? what is the difference between
PKCS#11 and PKCS#15??PKCS is the abbreviation of "Public-Key Cryptography Standards"
PKCS #11: Cryptographic Token Interface Standard
See http://www.rsasecurity.com/rsalabs/node.asp?id=2133
PKCS #15: Cryptographic Token Information Format Standard
http://www.rsasecurity.com/rsalabs/node.asp?id=2141
If you want to use yor smartcard as secure token it doesn't have to be a JavaCard.
BTW: I don't remember a way to access PKCS#15 tokens on a JavaCard from within an oncard JavaCard program. If you want to use keys in your oncard program, you have to transfer it onto the card or generate it oncard and export the public key by your own oncard/offcard code.

Some question about fade in // fade out by hideEffect and showEffect in Actionscript

Some question about fade in // fade out by hideEffect and
showEffect in Actionscript
Please kindly take a look at the following page:
http://camusmiu.no-ip.com/HounganQuestion/PictureHolderTest.html
(can view source)
I tried to make an image preloaded and scale the image to
it's preferred size.
When I came to consolidate the stuff into a component, I
found the application goes weird as I implementation the show/hide
effect.
The third trial which just hide and show the images directly,
instead of using viewstack, fail to bring the second image onto
screen.
It just used fadeOut instead of fadeIn(you see there is a
flash of the second image)
After some study of showEffect and hideEffect behaviour,
seems the mechanism of hide/show a component works in this way:
this._fadeIn:Fade = new Fade();
this._fadeIn.alphaFrom = 0;
this._fadeIn.alphaTo = 1;
this._fadeIn.duration = 1000;
this._fadeOut:Fade = new Fade();
this._fadeOut.alphaFrom = 1;
this._fadeOut.alphaTo = 0;
this._fadeOut.duration = 1000;
Component_A.visible = true;
Component_A.setStyle("showEffect", this._fadeIn);
Component_A.setStyle("hideEffect", this._fadeOut);
then when I set Component_A.visible = false, the sequence
works like following:
Component_A.visible = true
Component_A.visible = true, alpha = 100;
Component_A.visible = true, alpha = 50;
Component_A.visible = true, alpha = 0;
Component_A.visible = false;
The above sequence works visa versa as:
Component_A.visible = false;
Component_A.visible = true, alpha = 0;
Component_A.visible = true, alpha = 50;
Component_A.visible = true, alpha = 100;
Component_A.visible = true;
(Correct me if i am wrong)
========================================================================================== ====
From what I observe from the application, I have two
question.
1) When more than one component using the this._fadeIn,
this_fadeOut as the hide/show effects, the component in instance of
this._fadeIn? will it mess out if more than one component using the
fadeIn instance in the same time?
2) from the third component, i.e. PictureHolder3, when I load
other the picture , it fade out the new image instead of fading
in... Seems there is problem if I hide show too frequent. I think
when I hide then show right the way, the component only do the hide
part...
Can someone pls look into it and tell me what I did wrong?
Cuz in normal practice I don't think appropriate to use ViewStack
in Actionscript...

Hello Jack,
Currently, you can only import an swf file or you can embed videos from youtube, vimeo etc. into Muse / add HTML5 Video to Your Website.

Some question about Toshiab reocvery disk for Satellite P300-133

Hello guys ,
I got some questions about unpleasant recovery surprises :
*1)* I just made recovery DVD using Toshiba Recovery Disk Creator and it initially asked for 2 DVDs - but when the first one was done it didn`t require a second blanc DVD . Is it possible all system files of Windows Vista to be written on 1 DVD ?
*2)* Could I reinstall Windows Vista using the HDD Recovery option ( by pressing F8 ) without using recovery DVD ?
*3)* Which HDD partitions`ll be formatted ( just system C: or both C: and E: ) using HDD recovery ?
*4)* What is recovery DVD - Image of the hard drives or Vista installation files ?
Its pretty bad idea not to include OS on DVD when I have paid for it.
Thanks for all the problems to Toshiba :(

1. I think the recovery disk creator means 2 CDs. I have a Portege M700 with Windows Vista and one DVD too. I recovered it and after this I have a clean Vista installation with all drivers and tools from Toshiba. Nothing is missing.
2. Yes, you can reinstall Vista using the HDD Recovery option when you press F8 at startup. You dont need the recovery DVD but you should create one when your HDD get some errors or something else. If you need a new Recovery DVD, you have pay for one.
3. The complete HDD and partitions will be formatted, so backup your data first on a DVD, external HDD, USB stick or something else.
After the reinstallation you have the factory settings.
4. The recovery DVD is an image of the HDD about the factory settings. If you make a recovery, there are all drivers and tools already installed. Of course on the disk are the installations files of Vista, but you can only use this DVD on your Satellite P300. The disk can not be used on an other Satellite or on a PC.
When you have more questions, have a look in the user manual. There are a many in formations about the recovery. Its in chapter 3.

Just installed iOS6, questions about "iMessage" and other things...

I've been a satisfied iOS4 user since I bought my iPhone4, but I was forced to install iOS6 tonight in order to download a "free" app. I found a few new icons on the screen along with about 200 percent more "Settings" I'd like to ask some questions about. I'm sure a few of these could be answered by doing a frantic and thorough search through weeks of posts but I'm a little short on time right now.
First, what exactly is iMessage? Looking at the page for it, I can't see any difference between it and regular text messages. The info page says its to avoid charges, but between my data plan and not being charged for text I don't see where theres any other benefit. The one person I text with the most recently asked me why I had not installed iMessage yet, and didn't have an answer when I asked him why I should. I guess he just wanted to see text replies in blue instead of green.
In a related bit, flipping through Settings>Messages>Send & Receive I find a "2 addresses" section, with my phone number in there as well as my email under "You can be reached by iMessage at:" and "Start new conversations from:". What good does it do iMessages to have my email address? Does the Mail app handle text as well as email addresses? That seems to be the only explanation, and also very odd to think I'd be trying to text through my Mail app.
Second, looking through the Settings>Mail I see now that I have an icloud email address as well as the mac.com address I've been desperately hanging on to for the past 10 years, and the me.com address they've been trying to force me into since those came out. (I was happy to see I could delete the me.com address from the phone. I wish I could delete it from the universe.)
I wasn't even aware there was a such thing as icloud.com addresses. When did this happen? What is it used for?
Third, under that icloud Setting I see a long list of apps with buttons labeled "Off" under it. What are those for? Under the Mac.com settings I see switches for "Mail" and "Notes", with Mail on and Notes off. The Notes app (which I haven't used since my old iPhone 3) still opens, regardless of this setting.
Fourth, I now have an item called "Facetime" under my Settings. It is off, but underneath it says "Your phone number and/or email address will be shared with people you call". I understand caller ID normally sends caller number info to the receiver, but why would someone need my email address if I call them?
Fifth, I now have a "Music" setting, at the bottom of which I see a "Home Sharing" item, which when clicked brings up my AppleID and asks me if I want to Sign Out or Cancel. What is Home Sharing? Its also at the bottom of the "Video" settings.
Sixth, now I have Twitter and Facebook settings? For what? I don't have accounts with either of those companies. So why have settings, especially since it asks me to create accounts and download apps for those companies right in the Settings?
Seventh, there is a camera icon on the unlock screen. Touching it causes the screen to bounce up about a quarter inch, almost but not quite revealing something behind it. I should probably just quit asking about this stuff already, but I'll take the bait - what is this now?
Finally, what is the Notification Center used for?
If I got a text under iOS4, it would put an alert on the Unlock screen. Scrolling through this huge list of things under the Notification settings I'm really blown away by all the apps set up to yell at me. I can see having an alert for a text message but Game Center? What the heck is that, and why is it set up to hit me with a "Badge App Icon" (whatever that is) when I get alerts from "Everyone". Similarly, the phone is set to alert me to something called a "Photostream Alert"? What is this? Why is there a Phone section for the Notification Center? So they can put a Notice on my screen to tell me the phone is ringing? Holy cow! The phone is set to send me alerts from the "Weather Widget". So if I miss the fact its raining there will be a message on my screen to let me know? Whats next - a buzzer to tell me I'm listening to music?
There's a lot more, like what would I need Passbook for when I have the actual movie tickets, gate boarding passes, coupons, etc in my hands, but we'll leave that for another time. Many thanks to all who can offer some answers to my questions above.

Some questions about configuration in MAX.

Hello,everyone!
I have some questions about configuration in MAX(I am a jackaroo for motion control development),I hope I can get your help.
I use PCI-7344+UMI-7764+Servo amplifier+Servo motor,my MAX version is 4.2 and I use NI-Motion7.5
My question as following:
1,In Axis Configuration,for motor type,why I must select stepper but not servo?my motor is servo motor!If I select Servo,my motor can't run,I don't know why.
If I select stepper,though motor can work but I can't test encoder in MAX.
2,In Stepper settings,for stepper loop mode,why I must select open-loop but not close-loop?If I select close-loop,the servo motor doesn't work too.
3,If I want my two servo motors run at different velocity,How shoud I do?It seems I just can set the same velocity in MAX for my two servo motors.
My English is poor,Pls pardon me!I come from China.
Thank you for your help!

And I use position control mode,thehe encoder's counts per revolution is 131072.I set the electronic gear ratio to 1:1 for drive.
Now,I can use Close-Loop to control the motor but still has some problems.When I configure it to run in closed loop mode, the motors behave strangely and never move to the target position.When I configure it to run in closed loop mode, the motors behave strangely and never move to the target position.The detail situation is as following
1,Motor can't run.
2, Or motor moves to a position, then moves in the same direction agian and eventually stops.
Except for the two points mentioned above,"Following Error" is occured frequently,I don't know why.
I am still not clear why I must set the motor type be stepper in MAX .
And I have another question:what the relationship between the steps and the counts?They have the proportion relations?I notice that there are a section said like this in help document: For proper closed-loop and p-command operation, steps per revolution/counts per revolution must be in the range of 1/32,767 < steps/counts < 32,767. An incorrect counts to steps ratio can result in failure to reach the target position and erroneous closed-loop stepper operation.
I am verry sorry I have too many questions!
I am very appreciate for your kingly help!Thanks again!

Questions about Contracts and New Phones

I've had some questions about how upgrading and adding new lines to a contract works and I haven't been able to find the answers through Google. First some background information: We started this most recent contract in September of 2011 and as such the current contract will end September of 2013. According to the phone information portal, all three of the devices on my account will be eligible for an upgrade this Saturday (May 4th, 2013). My daughters birthday just so happens to coincide with that date and as such we were planning on surprising her by taking her to buy a new phone and we are going to allow our son to upgrade his phone as he has been asking to for a while.
Is there any way of locking/limiting the amount of data allowed for each phone on a shared plan? I'm worried that my daughter will go way over our limit and not pay attention to the point where she will end up costing us a very large amount of money
Does adding a new line require the start of a new contract?
My son was interested in purchasing the "Samsung Galaxy S4" and has noticed that pre-orders for that phone are currently available. Is it possible to pre-order the phone on that date using the upgrade so that the price will be reduced?
If the answer to number 2 is a no, does adding the new line take away the upgrades from other phones or would he be able to go to the store past the release date and upgrade then?
Thanks for taking the time to read through all of this. Any help that I receive will be extremely appreciated.

1. Yes. There is an additional fee per line you wish to do this for. When you add the line you can choose this option and set the data amount it is allowed to use.
2. Yes. Each line is a separate contract with its own expiration date.
3. The contract starts when you sign up for the contract. The amount will be pro-rated on the plan if it is not started until part-way through your billing cycle that is what you are asking. Doing the pre-order just guarantees you the phone in case they sell out.
4. No it will not take any upgrades away as each line has its own termination date. You can move upgrades around between lines though.

A question about grub and USB

Hi All
I have a quick question about grub and USB that I can't quite find the answer to by searching. Most of the FAQs discuss booting a full linux dristribution from USB. My situation is this. I am getting a new computer with two drives, the second will be arch and the first will be Vista (for my wife). I want the computer to boot the same way that my wife's machine boots at work so I don't want to install grub on the MBR. So, is there a way to have all of the grub config files and kernels installed on the second drive and simply install to grub boot loader to the MBR of a USB stick? My goal would be to simply plug the USB stick into the new PC and boot arch from the second drive.
Thanks
Kev

i cant say for hp's
havent worked on any in a while
recent machines have been coupleof dell's , vaio & emachine
which dells do offer it at least the ones i tried , my laptop does(dell)
all home pc's are built by me which do offer to boot individual drives
what hp you getting it may tell in specs
are both discs sata? if so it might not offer this option with 2 drives of same interface
check your power supply alot of these preconfigured machines put cheap under reated power supplies in there
& will burn your motherboard i just replaced PS(250 watt) & mobo(845gvsr) in an emachines <cheap stuff<
i hope you researched the pc before buying ie : mobo, power supply are the biggest concerns
i find it much more benificial to build my own machine gives me peace at mind. the cost is sometimes more in $ but not always , your biggest expense is time researching hardware
if you live in usa the best places to start looking are bensbargains.net & pricewatch.com
i am not affiliated with either & niether sell the hardware they are just advertisers a place to buy
for costomized machines that i would trust is unitedmicro.com theyll asemble & test before shipping
i have gotten 2 machines so far from them with NO PROBLEMS with hardware (knock knock)
you may want to consider this in your next venture for pc

A few questions about MacBooks and Parallels Desktop.

I have a few questions about MacBooks and Parallels Desktop.
1) I understand I need at least 1GB of RAM to run Parallels Desktop but what about the hard drive, is the stock 60GB drive big enough?
2) Related to question 1, even if it was big enough to allow me to install and run Windows would the 60GB drive be enough if I wanted to install a Linux distribution as well?
3) This has nothing to do with Parallels Desktop but thought I'd ask it here anyway, do Apple Stores carry just the stock MacBooks, or do they carry other configurations?
Thanks
Keith

1. Depend on how intensive you use that HD for saving data on both Mac OS and XP. For standard installation on both OS X and XP, the space of 60 Gb is enough.
2. Same answer as no 1. You can install all three on that HD space, but the extra spacce available will be less and less for your data. You can save your data on external or back up on cd/dvd and erase it from the HD to keep the free space.
Remember to leave at least 2 or 3 Gb for virtual memory usage.
3. Just call them, maybe they don't have it in store stock, but by appointment they might configure one for you before your pick-up date.
Good Luck
