Sunfire V20z...general questions about VRM's, CPU's, and memory speed

I've got a Sun V20z that i'd like to get going, but have a few questions. I've only got 1 memory VRM for the server, and 2 CPU VRM's. Can I run a single CPU until I find another VRM for the board? I was looking at going with an Opteron 248. Also, I've got about sixteen 1GB PC2100 sticks of ECC registered ram i'd like to use, but the docs say it only handles PC2700. Does that mean it can't handle anything FASTER, or simply that NOTHING other than PC2700 will work? I was planning on sticking my Opteron in the CPU 0 slot, along with 4 sticks of that ram. Thanks for the help, you guys helped me with my Enterprise 3500 server last fall and it's humming along great!

Each cpu will need its own VRM.
That is a necessary component, to regulate the voltage
flowing through the cpu itself.
Go ahead and run it on a single cpu for now.
Install the second one when you have all the needed parts.
I would expect your RAM to just fail to function.
PC2100 memory doesn't clock fast enough for the system's memory bus.
The V20z System Specifications page in the SSH notes
that the computer is designed to use faster modules.
I would expect you to observe errors immediately at bootup.
If a system was designed to use PC2100 RAM and you install
PC2700 mudules to the slots, they would work very well.
Think of that as underclocking the RAM.
However your circumstances are the reverse -- the computer's data bus
would push your RAM beyond its design specifications.
Perhaps others can also contribute their experiences with this.
I've not had the opportunity to run a V20z, personally.

General Question about how to encrypt-decrypt and Digital signatures

Hi,
We're developing classes for encrypting and signing a txt message and for decrypting and validating the signature of the message. Everything works properly but I have several questions, they're not about code:
1st We're encrypting the message following this way:
-generating a number which is gonna be the password
-encrypting the message in AES with this password
-encrypting the with the public certificate of the receiver the password
-We pack everything, encrypted message+ encrypted password in a File with public key of the receiver.
The questions we have for this issue are:
-Is it okay? or can I do it more efficiently.
-is it a standard for developing encrypting software? We've followed java api tutorials
-Can we decrypt this message using comercial software? it just plain text(of course if we have the private key)
2nd We take this message and we sign it with our private key
-We use CMS classes from bouncycastle libraries
The questions we have for this issue are:
- How can I check , with comercial software, whether this message is signed ok and is valid.
- How can I know whether this way of signing is in compliance with PKCS7-CMS standard?
Thanks in advance
if you need more information ask me

The file multiscreen.html apepars to do the following:
It tests if the browser is running on a "hand held device".
This means it looks to see if the device name includes:
"blackberry","android","iphone","ipad","symbian","smartphone","ios","windows ce","webos"
If the answer is Hand-held then the HTML5 published module is loaded. Otherwise it loads swf.
I can see no check that Flash player is loaded before making the choice, nor does it check the compatability of the HTML5 on the "hand held" device. In other words it isn't very "smart"

General question about iTunes Match and multiple libraries

Hello to everyone,
I have a general question about the iTunes Match service, which is available since yesterday in my country (Italy). Currently my library situation is the following:
Computer A (desktop, Windows 7): "big" iTunes library (about 20 GB), at the moment not associated with my Apple ID
Computer B (MacBook Air 2011): "small" iTunes library (about 5 GB), associated with my Apple ID
At the moment, both my iOS devices (iPhone 4 and iPad 2) are synchronized with the smaller library on the MacBook Air.
Question is as follows: should I subscribe to iTunes Match, would it be possible to upload the "big" library (provided I associate it with my Apple ID) to iCloud while keeping my devices synchronized with the "small" one?
Ideally, at the end of the day, the situation should be the following: both iOS devices with music from the small library + possibility of downloading songs from iCloud (coming from the big one). Is this possible?
Maybe the question sounds stupid, but I want to be sure about this before paying for the service.
Thanks a lot.

Yes, you could also associate your larger library with iTunes match if you associated your Apple ID with it. However any purchases in the library made from another Apple ID will not be matched with iTunes much.
If both libraries are part of iTunes match, then all your devices will see all of the content from both libraries, which content you choose to have on those devices and which you have accessible via iTunes match is entirely up to you.

Newbie question - general question about e-mail sync

Hi,
I have a general question about email sync and BlackBerry smartphones. Are there any devices that allow email syncing with a Microsoft Exchange 2007 system that do not require the BlackBerry Enterprise server?
Thanks; sorry if this has been asked before but I was unable to find it in the forums, documentation, etc. Everything I found assumes that for this kind of environment you will be using a BlackBerry Enterprise solution, but I can't assume.
Thanks again.
Solved!
Go to Solution.

Hi and Welcome to the Forums!
If the Exchange server has anything that faces the internet (OWA, POP, IMAP), then BIS can be used to handle email (only email...calendar and contacts require BES to sync OTA).
Or, a PC, inside the network (but with an internet path) and logged into the email server (using Outlook), can be left running, using the RIM Desktop Software's Desktop Redirector capability to forward messages to the BB.
Those are basically the options.
Hope that helps! Let us know!

General Question about SAP Documentation. Where to find?

Hello,
I am relatively new in the SAP business and so I have some general questions about the SAP Documentation.
Often internet-links like
http://help.sap.com/printdocu/core/Print46c/en/data/pdf/FIBP/FI-AP-AP-PT.pdf
are posted here by group members.
But where do these group members find these documents?
All I can see at help.sap.com is IDES (the model company created by SAP)and the WWW-version of the SAP-Bibliothek.
Were can I find these PDF-Files?
I would appreciate any hint and tip!
Thank you!
Kakue

thats true! i dont know how to find either. Everytime i need something i ask on the forum.

Here's a very basic question about 2 TB external drives and Time Machine.

Here's a very basic question about 2 TB external drives and Time Machine.
Ihave a Mac Pro with a .75 TB and 1 TB drive. It also has a 1 TB 2ndinternal drive. My current external drive is too small so I'll begetting a 1.5 TB or 2 TB drive.
Obviouslythe new larger 2 TB drive will backup everything on the Mac Prointernal drive with Time Machine. But there will be 1 TB of space leftover going to waste.
ShouldI partition the external drive so that the TM portion will be 1 TB andthe use the remaining extra partition for additional file backups withCarbon Copy?
Thanks for any insights.
I tried searching around on the new Apple discussion forum, but I find it much harder to use than the old forum I used to use.

The problem with terabyte drives is that that a 3 TB is about as big as you can get without going into RAID territory. Ideally, a Time Machine drive should be 3 times as large as all the drives you are backing up. So, if you have 2.75 TB of internal storage, you should have 8 TB of Time Machine space.
Of course, that is "should". If your TB drives are mostly empty, then you can get away with something 3 times the size of your used disk space. Just remember that you are pushing it. Linc is right about Time Machine needing space to work.
It is unlikely that you have regular churn on 2.75 TB of disk. I suggest identifying which drives and folders have the most activity and excluding those drives and directories that don't change much. It would be better to archive the data that doesn't change often and keep it out of Time Machine. Then you may be able to get away with a 2 TB Time Machine drive.

John,
I'm not sure why you posted in the iMac forum so I'm going to attempt to get you to the correct spot. I would recommend reposting in the Time Machine Forum, this is part of the OS X forums (Leopard or Snow Leopard) because you are using Snow Leopard (your profile indicates you are) please click Apple Support Communities and type Snow Leopard. Then you can narrow the search down by clicking Refine this List.

USB/FireWire usage increases CPU temp and fan speed

Hi,
I'm curious, does the usage of USB and FireWire ports increase CPU temperature and fan speed...?
I have an M-Audio Fast Track USB interface plugged in and whenever I play any songs from iTunes using that interface as an output, my CPU temp increased and fan speed jumped from 2000 to 3300 rpm. And on separate occasion, an 8GB of file transfer from an external FireWire-based HDD had both fans speed up to 4,400 rpm.
Is this normal...? All these were done with an external display plugged onto the MBP with "clamshell" mode.

USB operations involves quite a bit of CPU action, Elphidieus.
Firewire places less demand on the CPU but, in a situation like the one you describe can involve both increases in power usage and in HD temperatures.
The fan speeds on Macs are not simply responsive to CPU usage. Both HD temps and power usage can also play a part in the equation that ultimately produces the fan speed. As HDs have much lower heat tolerance than CPUs you will find that it is quite common to see the fans ramp up when doing a large file transfer over FW (or USB, for that matter) , especially if the internal HD temp gets to over about 50-55º Celsius.
Cheers

Satellite C855 - Average CPU temperature and fan speed

Hello!
I've had this toshiba Satellite C855 since march this year. it's only recently that the CPU temp and Fan speeds have been worrying me.
When I'm not playing games or doing a livestream my CPU temp stays around 35-40% with the fanspeed at steady 50% or not on at all due to it been cool.
When I do play games however the fanspeed is going up to around 66-68% with the CPU been around 55-60%
I was wondering if this is normal? or do I need to clean it out by taking it apart. if it is the second option then I am worried since I do not want to damage anything inside. plus I am not that great with the inner workings of a computer.
Any help or information would be very appreciated thanks.

In my opinion there is no reason for panic. T is logic that under stress CPU activity is higher and CPU produces more heat. Notebook must be cooled down properly so sensors that control cooling fans register growing temperature and cooling fans will run on higher speed.
There is no reason for cleaning. And one day if that must be done please dont do it alone. You are not authorized for doing this.

Is there a free app that allows me to show cpu temp and fan speed in menu bar?

i want a free app that monitors cpu temp and fan speed and can display them in the menu bar of my MBA

A few question about iPhone OS in CS5 and CS5 in general.

Hi,
I'm an IT trainer and I am trying to introduce my students to programming for iPhone/iPod Touch. (They are Secondary 2 students. 14 years old) The school is using a windows computer and CS5 right now is the best for the class (Not a steep learning curve and a user-friendly program). I know about the problems over the iPhone OS in CS5 with Apple but I was told it is still available for use. Furthermore, we have no intention of bringing the apps created to the Apple Store. I've tried the trial version and before I make any purchase, I would actually like to ask a few questions.
Is the iPhone OS in the trial version itself complete? Is there anything left out from the trial version because when I tried it, it seems fine however I did not try publishing to an iPhone due to the certificates. Is there a reason for the certificate? Is there any way around it because if there isn't do I need to get a certificate for every single student? (I'm looking at a class of 40 students.) Is the certificate available for windows platform?
Lets say, I got myself a certificate, create a simple program and then publish it, can I immediately bring it over to iTunes and then sync? Will it work that way? I don't want it to be too tedious for the students to see the end result. I've done quite a few research and have come across people having problems bringing it into their devices. Those people mention about bringing it to Cydia and needing to jailbreak the device. The devices made available for the students are not jailbroken. Will iPhone OS with proper certification still need Cydia for use with their device? Will only jailbroken device allow a CS5 app? I hope you get what I'm trying to say. We as trainers do not support teaching students to jailbreak, so that's definitely a no-no.
Another thing about CS5. Previously I have called customer support about the CS4 the school is using now and the problem with nested animation when publishing the animation as a video file, is this problem still in CS5? Does CS5 allow nested animation to be published as a video file? If it isn't, is there any way around it?
Thank you for your time and patience in answering my questions.

Shafuraa

Could you guide me on this file size warning specific to zfs file system.
Many thanks in advance for your support,

General Questions about BI

Hello,
I want to get into SAP BI and have some questions about it.
Is there a big downside in installing only the BI components without the Java BI components, or is it even possible if you want to work with BI. What are the general differences between BI and Java BI?
I think the main aspects i will work with will be data warehousing and some basic reporting.
The reason why i'm asking is that i want to run the BI components in the same system as the ECC Server (its just a test system). I read that the Java BI component needs EPC and EP and that would probably be too much for a single system (6 GB RAM).
Thanks a lot in advance,
Martin

Thanks for your hints, they were really helpful.
As i mentioned i mainly want to work with the general Data Warehouse and Reporting capabilities, so i think it should be okay.
Actually i'm planing to write about BI and SAP within my master thesis.
Another question, what will be with SAP BI in the future regarding the Business Object acquisition? Is there still any point in learning SAP BI or will SAP BI disapear in the future? I heard that the basic BI functionality (e.g. Datawarehouse ) will still be used but the reporting capabilities would be disappear. I'm not sure if that is right and i'm really new to this topic. So any comments are welcome.
Thanks,
Martin

I have a handful of general questions about Firefox OS as a consumer..

I couldn't find a better place to post this, so I'm trying on here.
I'm in the market for a tablet (high-end), and I'm holding off on getting an Android-powered one because of Firefox OS. However, I have some general questions and concerns regarding performance, software and hardware. Here they are.
1. Is the Firefox OS interface as responsive as a native experience on say an iPad or an Android tablet? (Is there any lag on swipes between screens, button presses, etc?) If not, will it be in the future?
2. Will I miss the Android marketplace or the Apple app store, being restricted to only HTML5 apps? Do you think this will become an irrelevant question as the HTML5 app ecosystem grows?
3. Do you think the quality of HTML5 apps will be inferior to those from existing app stores because they are free?
4. Will the Firefox browser be the only one available in Firefox OS? (i.e. will there be the option to use Chrome, Opera or any other browser if the user so wishes?)
5. Will Firefox OS include useful utility apps, such as an alarm clock, a calendar, a weather app, etc?
6. I read a lot, both on the web (news, video game reviews), as well as ebooks. Will Firefox OS on a tablet be a pleasant experience conducive to e-reading? (Will it include a good ebook reader app?)
7. Will there be a high-end Firefox OS tablet that is comparable in specs to the Nexus 10? (i.e. impressive screen resolution, powerful CPU/GPU, lots of inputs/outputs like USB, HDMI, microSD, etc) When do you think such a device might become available?
8. Would it be possible to flash Firefox OS onto say a Nexus 10 or other tablet or phone if one wanted to use it as their OS instead?
Thanks!

1. Depends on the phone but a avererage power android phone would likely cost the same as a high end firefox os phone.
2. HTML 5 is really the future of the web, I've heard that Firefox will let you package apps to be playable offline, but not sure if thats true.
3. I '''think''' Firefox OS may have paid apps that will be restricted to users who buy them.
4. I think Mozilla will be nice enough to let Google and Opera make browsers. Google let Mozilla do that with FF for android.
5. See the simulator https://addons.mozilla.org/en-us/firefox/addon/firefox-os-simulator/
6. too early to say
7. too early to say, but Foxconn (helps apple) makes some apple products, so yes in the future is see a high end Firefox OS tablet 2-3 years down the road.
8. not sure
NOTE: Please note that we are only contributors, we dont develop firefox os.
You can ask more on the IRC channel as there are likely devs there.

Asking general questions about 'computing' matters.

Hello
I'm new to the Mac world - I posted my first question on the forums today!
I have reviewed the discussions site - everything seems very specific to apple products. Where, if anywhere, could I post a general question - like this one:-
I have a notion that when one connects to a server directly (Usenet newsgroups for example) one makes a deliberate 'hole' in one's firewall, be it software or simply because one is using a NAT router. Sending messages to and receiving posts from Usenet is far quicker than using email, so I'm fairly confident that this is so.
I am well aware that any URL one visits can instantly determine much information about the connecting machine. (see http://www.browserreport.com/ as an example).
Anti-malware programs can only detect known viruses and spyware - I see no reason at all why, once one has granted a direct connection facility, between a group on a private server to
one's own machine, malware could not relatively simply be injected onto one's computer.
If the malware was currently unknown, how would one ever know?
Thanks in anticipation of a helpful response

Unfortunately, not in this forum. This forum is specifically about the discussion forum itself. It is kind of like a meta-forum. Hopefully, the moderators will just move your post somewhere more appropriate. (As indeed they just did!)

Kind of and kind of not. Firewalls are greatly misunderstood. But essentially, yes, any internet connection you establish has some risk involved. However, the risk of making an outgoing connection is infinitesimally smaller than setting up a server to let hackers bang on 24x7.
Sending messages to and receiving posts from Usenet is far quicker than using email, so I'm fairly confident that this is so.
Really? I don't think so.
I am well aware that any URL one visits can instantly determine much information about the connecting machine. (see http://www.browserreport.com/ as an example).
Not really. It depends on what you are doing. You always give away your IP address, unless you are behind a proxy. In that case, you give away the proxy's IP address. But the proxy still knows who you really are.
If the protocol in question supports such information, then it can be determined. A web browser does send some information about you, but you can easily change it and masquerade as some other browser. With other protocols, it isn't so easy to tell what kind of OS or software is being used.
Anti-malware programs can only detect known viruses and spyware - I see no reason at all why, once one has granted a direct connection facility, between a group on a private server to
one's own machine, malware could not relatively simply be injected onto one's computer.
If the malware was currently unknown, how would one ever know?
You wouldn't
Don't grant anyone direct connection to your machine.
