What is the slot order for mixing memory

I have a new Mac Pro (8 core) and I installed 4 4-gig memory modules (slots 1,2,5,6). I also have 6 1-gig modules that I removed to make room for the 4-gig modules. I thought I could use 4 on the 1-gig modules in the empty bays for a total of 20 gigs. However, when I install the 1-gig modules I get a blinking power light and the machine never boots.
Am I placing the modules in the wrong slots, or is it not possible to mix modules like this?

Apple seemed to think mixing wouldn't be a problem, unless the real world is different. Did you follow the placement shown in this PDF? Might still want to try putting in only two 1 gbs though, you'll still have plenty of RAM and, according to this Apple quote,
"For optimal memory bandwidth, all six memory channels should be used, and memory should be balanced across the six channels.".
"Populating slot 4 or 8 slightly drops maximum memory bandwidth, but depending on the applications used, overall system performance may benefit from the larger amount of memory".
http://manuals.info.apple.com/enUS/Mac_Pro_Early2009_Memory_DIMMDIY.pdf
Shouldn't hurt to try... Per the manual, if your Mac blows up, Apple would have to replace it.
If you can get all your RAM to completely show up, the 4gb RAM, that's the time to monitor things and test without the added sticks. Once the Mac runs smoothly for awhile and the RAM consistently shows up, then I think that might be the best time to try the other sticks and see what happens..
Really have to make sure that RAM is seated well, and it wouldn't be a bad idea to do a SMC reset while you're in there. It sometimes unsticks, sticky RAM.
Good luck.

What's the recommended setting for "Process memory usage" ("process virtual" in UI) for a 64-bit host on a 64-bit OS?

Hi gurus
In resource based throttling, what's the recommended setting for "Process memory usage" ("process virtual" in the resource based throttling tab of the UI) for a 64-bit host
on a 64-bit Windows OS?
According to MS (http://msdn.microsoft.com/en-us/library/ee308808(v=bts.10).aspx):
"By default, the
Process memory usage throttling threshold is set to 25. If this value is exceeded and the BizTalk process memory usage is more than 300 MB, a throttling condition may occur. On a 32-bit
server, you can increase the Process memory usage value to 50. On a 64-bit server, you can increase this value to 100. This allows for more memory consumption by the BizTalk process before throttling
occurs."
Does this mean that 100 is the recommended setting for a 64-bit host on a 64-bit Windows?
Thanks
Michael Brandt Lassen

Hi Michael,
Recommended setting is the default setting which is 25 .dot.
If your situation is abnormal and you see message delivery throttling state to “4” when the following performance counters are high or if you expect any of you integration
process could have impact on following counters, then you can consider the suggestion by Microsoft. Don’t change the default setting.
High process memory
Process memory usage (MB)
Process memory usage threshold (MB)
You can see these counters under “BizTalk:MessageAgent”
You can gauge these performance counter and its maximum values if have done any regression/performance testing in your test servers. If you have seen these counters having
high values and causing throttling, then you can update the Process memory usage.
Or unexpectedly you’re process high throughput messages in production which is causing these counters to go high and cause throttling, then up can update the Process memory
usage.
The above two cases where I know my expected process usage (by doing performance testing) or suddenly my production server processing has gone high due to unexpected business
hike (or any reasons) which caused throttling, then do changes to default throttling setting.
Just changing the default setting without actual reason could have adverse effect where you end up allocating
more processing capacities but the actual message processing message usage ever is low means you end up investing in underutilised resources.

What's the best order for mac os x?

Hello, i was wandering about the best order for the RAM clips (when they're different in size, of course).
Should i place my little one clip in the lower slot and my big one clip in the upper slot, or the opposite, ...or did mac os x worth about it for the performances to be better?
Thanks for your comments.

The slots are very specific about the kind of RAM they can accept. If you simply bought RAM based on the generic spec, you may have bought the wrong RAM. Be sure to buy from a vendor that is specific about your Mac model when asking for RAM. http://www.crucial.com/ has a much better handle than most in giving you the right RAM. The height of the module may affect clearance or heat or bus slewing issues with the logicboard, so be sure to put only the height that was already in the computer. If uncertain, find better instructions that show you. See my FAQ*:
http://www.macmaps.com/badram.html
Mac OS X performance is best when you install exactly according to manufacturer spec, and not from some generic spec.

What's the sort order for podcasts on the shuffle?

Hi all... Can someone tell me how the iPod Shuffle orders podcasts? I've seen MANY posts saying there's no way to manually sort podcasts on the shuffle (which is crazy IMO), but at least if I know how it's ordering the podcasts that'll help me identify which one is next.
I added 15 podcasts to the shuffle, and sorting by every category I can find none that matches the order the shuffle places the podcasts in.
So first question -- what order are the podcasts stored in?
And second question -- Why the heck did Apple do this? Why can't podcasts just be treated like standard MP3 songs?
And finally if there's no answer to either of these, is there anyway to get ipodderx to sync to the ipod shuffle? I love itunes, but if it's going to hender my hardware I'll switch to something else.
Thanks for any help on this, and take care --
Sam

Hi Dean,
I'm wondering if something's wrong with my podcast, because that's not what happens on mine. For example I have my podcasts in this order:
NPR Technology
Haunted New Jersey
Autumn in New England
Hometown Tales Podcast
And even after selecting File then Update iPod and even right-clicking on ipod and selecting Copy to Play Order the order of the podcasts are :
Haunted New Jersey
Hometown Tales Podcast
NPR Technology
Hometown Tale Podcast
Nothing I've done sorts the podcasts as they should be sort. Also i set it to not show the ipod unless it's connected, and when I sort the podcasts as I want, Update ipod, and plug ipod, plugging it back in shows the wacky sort order they're stored on the ipod. I can rearrange again, update again, eject and plug back in, and the crazy sort order (not mine) is back.
Is there something I'm missing????

What are the User Exits for Sales Order creation process?

Hi,
what are the User Exits for Sales Order creation process? how can I find them?
thanks in advance,
will reward,
Mindaugas

Please check this info:
User Exits In Sales Document Processing
This IMG step describes additional installation-specific processing in sales document processing. In particular, the required INCLUDES and user exits are described.
Involved program components
System modifications for sales document processing affect different areas. Depending on the modification, you make the changes in the program components provided:
MV45ATZZ
For entering metadata for sales document processing. User-specific metadata must start with "ZZ".
MV45AOZZ
For entering additional installation-specific modules for sales document processing which are called up by the screen and run under PBO (Process Before Output) prior to output of the screen. The modules must start with "ZZ".
MV45AIZZ
For entering additional installation-specific modules for sales document processing. These are called up by the screen and run under PAI (Process After Input) after data input (for example, data validation). The modules must start with "ZZ".
MV45AFZZ and MV45EFZ1
For entering installation-specific FORM routines and for using user exits, which may be required and can be used if necessary. These program components are called up by the modules in MV45AOZZ or MV45AIZZ.
User exits in the program MV45AFZZ
The user exits which you can use for modifications in sales document processing are listed below.
USEREXIT_DELETE_DOCUMENT
This user exit can be used for deleting data which was stored in a separate table during sales document creation, for example, if the sales document is deleted.
For example, if an additional table is filled with the name of the person in charge (ERNAM) during order entry, this data can also be deleted after the sales order has been deleted.
The user exit is called up at the end of the FORM routine BELEG_LOESCHEN shortly before the routine BELEG_SICHERN.
USEREXIT_FIELD_MODIFICATION
This user exit can be used to modify the attributes of the screen fields.
To do this, the screen fields are allocated to so-called modification groups 1 - 4 and can be edited together during a modification in ABAP. If a field has no field name, it cannot be allocated to a group.
The usage of the field groups (modification group 1-4) is as follows:
Modification group 1: Automatic modification with transaction MFAW
Modification group 2: It contains 'LOO' for step loop fields
Modification group 3: For modifications which depend on check tables or on other fixed information
Modification group 4: is not used
The FORM routine is called up for every field of a screen. If you require changes to be made, you must make them in this user exit.
This FORM routine is called up by the module FELDAUSWAHL.
See the Screen Painter manual for further information on structuring the interface.
USEREXIT_MOVE_FIELD_TO_VBAK
Use this user exit to assign values to new fields at sales document header level. It is described in the section "Transfer of the customer master fields into the sales document".
The user exit is called up at the end of the FORM routine VBAK_FUELLEN.
USEREXIT_MOVE_FIELD_TO_VBAP
Use this user exit to assign values to new fields at sales document item level. It is described in the section "Copy customer master fields into the sales document".
The user exit is called up at the end of the FORM routine VBAP_FUELLEN.
USEREXIT_MOVE_FIELD_TO_VBEP
Use this user exit to assign values to new fields at the level of the sales document schedule lines.
The user exit is called up at the end of the FORM routine VBEP_FUELLEN.
USEREXIT_MOVE_FIELD_TO_VBKD
Use this user exit to assign values to new fields for business data of the sales document. It is described in the section "Copy customer master fields into sales document".
The user exit is called up at the end of the FORM routine VBKD_FUELLEN.
USEREXIT_NUMBER_RANGE
Use this user exit to define the number ranges for internal document number assignment depending on the required fields. For example, if you want to define the number range depending on the sales organization (VKORG) or on the selling company (VKBUR), use this user exit.
The user exit is called up in the FORM routine BELEG_SICHERN.
USEREXIT_PRICING_PREPARE_TKOMK
Use this user exit if you want to include and assign a value to an additional header field in the communication structure KOMK taken as a basis for pricing.
USEREXIT_PRICING_PREPARE_TKOMP
Use this user exit if you want to include or assign a value to an additional item field in the communication structure KOMP taken as a basis for pricing.
USEREXIT_READ_DOCUMENT
You use this user exit if further additional tables are to be read when importing TA01 or TA02.
The user exit is called up at the end of the FORM routine BELEG_LESEN.
USEREXIT_SAVE_DOCUMENT
Use this user exit to fill user-specific statistics update tables.
The user exit is called up by the FORM routine BELEG-SICHERN before the COMMIT command.
Note
If a standard field is changed, the field r185d-dataloss is set to X. The system queries this indicator at the beginning of the safety routine. This is why this indicator must also be set during the maintenance of user-specific tables that are also to be saved.
USEREXIT_SAVE_DOCUMENT_PREPARE
Use this user exit to make certain changes or checks immediately before saving a document. It is the last possibility for changing or checking a document before posting.
The user exit is carried out at the beginning of the FORM routine BELEG_SICHERN.
User exits in the program MV45AFZA
USEREXIT_MOVE_FIELD_TO_KOMKD
Use this user exit to include or assign values to additional header fields in the communication structure KOMKD taken as a basis for the material determination. This is described in detail in the section "New fields for material determination".
USEREXIT_MOVE_FIELD_TO_KOMPD
Use this user exit to include or assign values to additional item fields in the communication structure KOMPD taken as a basis for the material determination. This is described in detail in the section "New fields for material determination".
USEREXIT_MOVE_FIELD_TO_KOMKG
Use this user exit to include or assign values to additional fields in the communication structure KOMKG taken as a basis for material determination and material listing. This is described in detail in the section "New fields for listing/exclusion".
USEREXIT_MOVE_FIELD_TO_KOMPG
Use this user exit to include or assign values to additional fields in the communication structure KOMPG taken as a basis for material determination and material listung. This is described in detail in the section "New fields for listing/exclusion".
USEREXIT_REFRESH_DOCUMENT
With this user exit, you can reset certain customer-specific fields as soon as processing of a sales document is finished and before the following document is edited.
For example, if the credit limit of the sold-to party is read during document processing, in each case it must be reset again before processing the next document so that the credit limit is not used for the sold-to party of the following document.
The user exit is executed when a document is saved if you leave the processing of a document with F3 or F15.
The user exit is called up at the end of the FORM routine BELEG_INITIALISIEREN.

I have a Mac OSX 10.5.8 processor dual 2 ghz powerpc g5 what is the next update for that?

There is none. You are at the end for a PPC machine. To upgrade you need to purchase an Intel Mac.
Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You must purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s iCloud services; fees and
           terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion - System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later
         7. Xserve (Early 2009) - Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
     Are my applications compatible?

What is the best app for Maintenance/Cleanup for my mac? Do I need Virus Protection?

What is the best app for Maintenance/Cleanup for my Mac? Do I need Virus protection?

How to maintain a Mac
Make two or more backups of all your files
One backup is not enough to be safe. A copy of a backup doesn't count as another backup; all backups must be made directly from the original data.
Keep at least one backup off site at all times in case of disaster. Backing up to a cloud-data service is one way to accomplish this, but don't rely exclusively on such backups.
In fact, don’t rely exclusively on any single backup method, such as Time Machine.
If you get an indication that a backup has failed, don't ignore it.
Keep your software up to date
In the App Store or Software Update preference pane (depending on the OS version), you can configure automatic notifications of updates to OS X and other Mac App Store products. Some third-party applications from other sources have a similar feature, if you don’t mind letting them phone home. Otherwise you have to check yourself on a regular basis.
Keeping up to date is especially important for complex software that modifies the operating system, such as device drivers. Don't install such modifications unless they're absolutely necessary. Remove them when they are no longer needed. Before installing any Apple update, you must check that all system modifications that you use are compatible. Incompatibility with third-party software is by far the most common cause of difficulties with system updates.
Don't install crapware
...such as “themes,” "haxies," “add-ons,” “toolbars,” “enhancers," “optimizers,” “accelerators,” "boosters," “extenders,” “cleaners,” "doctors," "tune-ups," “defragmenters,” “firewalls,” "barriers," “guardians,” “defenders,” “protectors,” most “plugins,” commercial "virus scanners,” "disk tools," or "utilities." With very few exceptions, such stuff is useless or worse than useless. Above all, avoid any software that purports to change the look and feel of the user interface.
It's not much of an exaggeration to say that the whole "utility" software industry for the Mac is a fraud on consumers. The most extreme examples are the "CleanMyMac," "TuneUpMyMac," and “MacKeeper” scams, but there are many others.
As a rule, you should avoid software that changes the way other software works. Plugins for Photoshop and similar programs are an obvious exception to this rule. Safari extensions, and perhaps the equivalent for other web browsers, are a partial exception. Most are safe, and they're easy to get rid of if they don't work. Some may cause the browser to crash or otherwise malfunction. Some are malicious. Use with caution, and install only well-known extensions from relatively trustworthy sources, such as the Safari Extensions Gallery.
Only install software that is useful to you, not (as you imagine) to the computer. For example, a word processor is useful for writing. A video editor is useful for making movies. A game is useful for fun. But a "cache cleaner" isn't useful for anything. You didn't buy a computer so you could clean caches.
Never install any third-party software unless you know how to uninstall it. Otherwise you may create problems that are very hard to solve. Do not rely on "utilities" such as "AppCleaner" and the like that purport to remove software.
Don't install bad, conflicting, or unnecessary fonts
Whenever you install new fonts, use the validation feature of the built-in Font Book application to make sure the fonts aren't defective and don't conflict with each other or with others that you already have. See the built-in help and this support article for instructions.
Deactivate or remove fonts that you don't really need to speed up application launching.
Avoid malware
"Malware" is malicious software that circulates on the Internet. This kind of attack on OS X was once so rare that it was hardly a concern, but it's now increasingly common and dangerous.
There is some built-in protection against malware, but you can’t rely on it—the attackers are always at least one day ahead of the defense. You can’t rely on third-party "anti-virus" products for protection either. What you can rely on is common-sense awareness—not paranoia, which only makes you more vulnerable.
Never install software from an untrustworthy or unknown source. If in doubt, do some research. Any website that prompts you to install a “codec” or “plugin” that comes from the same site, or an unknown site, is untrustworthy. Software with a corporate brand, such as Adobe Flash Player, must come directly from the developer's website. No intermediary is acceptable, and don’t trust links unless you know how to parse them. Any file that is automatically downloaded from the web, without your having requested it, should go straight into the Trash. A web page that tells you that your computer has a “virus,” or that anything else is wrong with it, is a scam.
In OS X 10.7.5 or later, downloaded applications and Installer packages that have not been digitally signed by a developer registered with Apple are blocked from loading by default. The block can be overridden, but think carefully before you do so.
Because of recurring security issues in Java, it’s best to disable it in your web browsers, if it’s installed. Few websites have Java content nowadays, so you won’t be missing much. This action is mandatory if you’re running any version of OS X older than 10.6.8 with the latest Java update. Note: Java has nothing to do with JavaScript, despite the similar names. Don't install Java unless you're sure you need it. Most people don't.
Don't fill up your disk or SSD
A common mistake is adding more and more large files to your home folder until you start to get warnings that you're out of space, which may be followed in short order by a startup failure. This is more prone to happen on the newer Macs that come with an internal SSD instead of the traditional hard drive. The drive can be very nearly full before you become aware of the problem.
While it's not true that you should or must keep any particular percentage of space free, you should monitor your storage use and make sure you're not in immediate danger of using it up. According to Apple documentation, you need at least 9 GB of free space on the startup volume for normal operation.
If storage space is running low, use a tool such as OmniDiskSweeper to explore the volume and find out what's taking up the most space. Move seldom-used large files to secondary storage.
Relax, don’t do it
Besides the above, no routine maintenance is necessary or beneficial for the vast majority of users; specifically not “cleaning caches,” “zapping the PRAM,” "resetting the SMC," “rebuilding the directory,” "defragmenting the drive," “running periodic scripts,” “dumping logs,” "deleting temp files," “scanning for viruses,” "purging memory," "checking for bad blocks," "testing the hardware," or “repairing permissions.” Such measures are either completely pointless or are useful only for solving problems, not for prevention.
To use a Mac effectively, you have to free yourself from the Windows mindset that every computer needs regular downtime for maintenance such as "defragging" and "registry cleaning." Those concepts do not apply to the Mac platform.
A well-designed computing device is not something you should have to think about much. It should be an almost transparent medium through which you communicate, work, and play. If you want a machine that needs a lot of attention just to keep going, use a PC, or collect antique cars.
The very height of futility is running an expensive third-party application called “Disk Warrior” when nothing is wrong, or even when something is wrong and you have backups, which you must have. Disk Warrior is a data-salvage tool, not a maintenance tool, and you will never need it if your backups are adequate. Don’t waste money on it or anything like it.

I now have 4 itouchs, 1 ipad mini, and three iphones for my own family members. What's the bet way for me to setup itunes so that we can all share the same music, apps, movies, shows, etc?

I now have 4 itouches, 1 ipad mini and 3 iphones in use by my direct family. What's the best way for me to set things up so that we can all share the same music, apps, movies, shows etc?
I would prefer to have one account to input dollars which allows all the users (my direct family) to share and buy things.
Can we all have different user ID's however share the same account?

I'll try to help a bit.
ITunes match space is different to icloud space. With iTunes match you get storage for 25,000 non iTunes purchased tracks and other than a limit for individual file size, there is no memory limit.
You can turn match on individuallyon each device (I have it turned off on my iPod but turned on on my iPad and iPhone). When you turn it on then you get access to all the tracks, and in my experience any playlists I create have transferred over very well. I understand that some people have had trouble with playlists though.
I'm not quite clear with exactly what you mean regarding cleaning up your library, but be careful about using Match for this. There is no guarantee that matched songs will be exactly the same version as your own copy, due to some mismatches, so you could find some problems there. Personall, I am cleaning up my library before matching, but I am rather particular about keeping my library the way I want it. If you aren't as fussed then match could be the answer.
Hope that helped.

What is the best practice for changing view states?

I have a component with two Pie Charts that display
percentages at two specific dates (think start and end values).
But, I have three views: Start Value only, End Value only, or show
Both. I am using a ToggleButtonBar to control the display. What is
the best practice for changing this kind of view state? Right now
(since this code was inherited), the view states are changed in an
ActionScript function which sets the visible and includeInLayout
properties on each Pie Chart based on the selectedIndex of the
ToggleButtonBar, but, this just doesn't seem like the best way to
do this - not very dynamic. I'd like to be able to change the state
based on the name of the selectedItem, in case the order of the
ToggleButtons changes, and since I am storing the name of the
selectedItem for future reference.
Would using States be better? If so, what would be the best
way to implement this?
Thanks.

I would stick with non-states, as I have always heard that
states are more for smaller components that need to change under
certain conditions, like a login screen that changes if the user
needs to register.
That said, if the UI of what you are dealing with is not
overly complex, and if it will not become overly complex, maybe
states is the way to go.
Looking at your code, I don't think you'll save much in terms
of lines of code.

What's the better order to install OEM + AS + DB

Hi everbody.
What's the better order to install on RHEL4 Update2:
- Enterprise Manager Control Grid (10gR2)
- Database (10gR2)
- Application Server (10gR3)
And about the $ORACLE_HOME?? How to? Each instalation have a separate $ORACLE_HOME??
Tks!

Rafael,
Save the Grid Control as the last installation. The order of Database and Application Server doesn't matter, however I would personally install the database first.
Please read all Installation Guides' before starting any installations, and follow all pre-requisites stated for RHEL4.
The Installation Guide's states that all products must be installed in separate ORACLE_HOME. As a matter of fact, the Oracle Installer doesn't allow installing any of these products into an existing ORACLE_HOME.

Martin

What is the Best practice for ceramic industry?

Dear All;
i would like to ask two questions:
1- which manufacturing category (process or discrete) fit ceramic industry?
2- what is the Best practice for ceramic industry?
please note from the below link
[https://websmp103.sap-ag.de/~form/sapnet?_FRAME=CONTAINER&_OBJECT=011000358700000409682008E ]
i recognized that ceramic industry is under category called building material which in turn under mill product and mining
but there is no best practices for building material or even mill product and only fabricated meta and mining best practices is available.
thanks in advance

Hi,
I understand that you refer to production of ceramic tiles. The solution for PP was process, with these setps: raw materials preparation (glazes and frits), dry pressing (I don't know extrusion process), glazing, firing (single fire), sorting and packing. In Spain, usually are All-in-one solutions (R/3 o ECC solutions). Perhaps the production of decors have fast firing and additional processes.
In my opinion, the curiosity is in batch determination in SD, that you must determine in sales order because builders want that the order will be homogeneus in tone and caliber, and he/she can split the order in diferents deliveries. You must think that batch is tone (diferents colours in firing and so on) and in caliber.
I hope this helps you
Regards,
Eduardo

What is the part number for the fan for the dv7 2270 us

what is the part number for the fan for the dv7 2270 us

Dear Kamat,
The HP manual (http://h10032.www1.hp.com/ctg/Manual/c01689926.pdf) says that the Fan/Heat sink assembly (depending on the graphics subsystems memory type), can be the following:
516876-001 (for discrete)
516331-001 (for UMA)
I dont know what graphics subsystem type is the DV7-2270US (VM189UA), but it doesnt matter in this case, becouse, if you search for those two part numbers, no one of them, is used in that computer. Check it your self:

What's the best SSD for a Macbook Pro 13" Mid 2010?

Hello.
I will upgrade my 2010 Macbook Pro. I need to know what's the best SSD for my Macbook Pro. I was thinking about those:
- Kingston SSDNow V+200 (SVP200S37A/120G) - 120 GB
- CRUCIAL SSD M4 128 GB
- CORSAIR SSD Force Series GS 128 GB
- SAMSUNG SSD 840 Series Basic 2.5" - 120 GB (MZ-7TD120BW)
- CRUCIAL SSD interno Crucial v4 - 128 GB
Those are the easiest to find on Portugal.

It is my understanding that SATA III is backwards compatible to SATA II so that should not be an issue for your selection process.
As an aside, you might be interested to know that your MBP can now have 16 GB RAM installed.

What is the best antivirus for MacBook Pro?

What is the best antivirus for MacBook Pro?

1. This comment applies to malicious software ("malware") that's installed unwittingly by the victim of a network attack. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
If you find this comment too long or too technical, read only sections 5, 6, and 10.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
It can easily be disabled or overridden by the user.
A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
For the reasons given above, App Store products, and other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. OS X security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is presumably effective against known attacks, but maybe not against unknown attacks. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. XProtect, Gatekeeper, and MRT reduce the risk of malware attack, but they're not absolute protection. The first and best line of defense is always your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the malware attacker. If you're smarter than he thinks you are, you'll win.
That means, in practice, that you never use software that comes from an untrustworthy source, or that does something inherently untrustworthy. How do you know what is trustworthy?
Any website that prompts you to install a “codec,” “plug-in,” "player," "extractor," or “certificate” that comes from that same site, or an unknown one, is untrustworthy.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
Software that purports to help you do something that's illegal or that infringes copyright, such as saving streamed audio or video for reuse without permission, is unsafe. All YouTube "downloaders" are in this category, though not all are necessarily harmful.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe.
Even signed applications, no matter what the source, should not be trusted if they do something unexpected, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it — not JavaScript — in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
Follow the above guidelines, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself from malware.
7. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. Any database of known threats is always going to be out of date. Most of the danger is from unknown threats. If you need to be able to detect Windows malware in your files, use one of the free anti-virus products in the Mac App Store — nothing else.
Why shouldn't you use commercial "anti-virus" products?
Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
8. An anti-malware product from the App Store, such as "ClamXav," doesn't have these drawbacks. That doesn't mean it's entirely safe. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
An anti-virus app is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
Anti-virus software may be able to tell you which particular virus or trojan it is, but do you care? In practice, there's seldom a reason to use the software unless a network administrator requires you to do it.
The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have the disadvantages mentioned in section 7.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
10. As a Mac user you don't have to live in fear that your computer is going to be infected every time you install an application, read email, or visit a web page. But neither should you have the false idea that you will always be safe, no matter what you do. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.
