Difference between InvisibleShield, Ghost Armor, Clear Shield

They all say that each was originally used to "used to protect the leading edges of military helicopter blades from wear and tear" or protect helicopter blades in Desert Storm from sand or something. Why are there different companies making the same exact product? I'm a bit confused on this (apparently theres some minor difference between Invisible Shield and Ghost Armor.. apparently Ghost armor's a little better)

Let me tell you why you DO need a screen protector.
I had a Dell AXIM for 2-3 years. Used it with an awesome screen protector (i can't remember the name, it's a static cling, washable, reusable film). I had it on the device from day one. I didn't smudge and I never had any problems until the day I dropped the device face first on a pebble getting out of my car. The protector had a dent and I thought the screen has a chip. I peeled the film of to reveal an immaculate screen without any scratches.
Now, on the other hand, I have an expensive watch with a scratch resistant glass. I dropped that by mistake and it his something on the concrete and I had a very expensive dot on its face. Now, I don't expect anyone to use a screen protector on a watch but if $10 will maintain an immaculate screen i think it's worth it.
Now, If I just could find the same screen protector I had on my AXIM I would buy it in an instant. It was smudge resistant too. I'm on my 4th cheap film and they either smudge or they are sticky.

Difference Between RE and RM sales order type

Hello friends...
Can anyone tell me what is the difference between the sales cycles if i take sales order RE and RM type.
RE- Return Sales Order
RM- Delivery Order return
Difference between them is not clear...it will be good..if explain with some example.
Thanx
siddharth

Hi
Returns for Delivery Orders
You can create a return for delivery order items.
When processing returns for delivery orders, note that:
u2022     The standard system contains the sales document type RM for delivery order returns. You create a return for delivery orders in the same way as a standard return.
u2022     Choose Goods issue to post goods receipt.
u2022     Cumulative quantities are not updated automatically. You must correct them manually.

Difference between cleared items,open items and all postings (FI).

Hi experts,
Can anybody tell me the difference between cleared items,open items and all postings for an account.
While running corresponding bapis and transaction FAGLL03 (for GL) or FBL1N (for accounts payable) i found that in some cases all postings is less than cleared items or open items for a time period. How could it happen.According to my knowledge all postings should contain cleared items and open items.
Please correct me..
Thanks and Regards
Arjun

Hi Arjun,
For every Billing Documnet created(VBRK/VBRP-VBELN) there will be an accounting document created in BSID/BSAD tables.
OPEN ITEMS means the Billed/Invoice Amounts that are pending from Customers, i.e which we have to receive from Customers.
CLOSED ITEMS means the AMOUNTS received from that customer.
OPEN ITEMS : fetch data from BSID table Only
CLOSED ITEMS : fetch data from BSAD only.
ALL POSTINGS : fetch data from both BSID and BSAD.
Hope this will help.

Nitin.

Difference between vector obj.clear() and Vector obj = null

What is the difference between clearing the Vector object with .clear() method and assigning null value to Vector object?
As per memory point of view, is it advisable to first clear vector and then assaign it to null for garbage collection or it doesn't make any difference.
Vector may contains large volume of data.
Please reply this if any one has fair idea regarding this.
Thanks in advance.
Deepalee

What is the difference between clearing the Vector
object with .clear() method and assigning null value
to Vector object?
Vector victor = new Vector(); //victor is a reference to a Vector object
victor.clear(); //now that Vector object has no elements
victor = null; //now victor is a null reference; it doesn't point to any Vector object
//if that was the only reference to that Vector, the Vector is now available to be GC'ed.
As per memory point of view, is it advisable to first
clear vector and then assaign it to null for garbage
collection or it doesn't make any difference.Hard to say. My gut says there will be no advantages to first clearing it. You'd have to try and measure.

Unable to clear GL due to Val difference between Local and group currency.

hi,
We have an open item managed Revaluation G/L account in our company code which has a local currency USD.There are some documents posted to this account in both USD and CAD. But when we analyze the docs posted in CAD we found a valuation difference in the local currency(USD) and the Group currency(again USD). I am not sure of the reason for this. But due to this difference we are unable to clear this account. Please let me know if anyone can think of how to clear this particular GL account.
Rgds,
Raj/
Edited by: raj3875 on Oct 8, 2009 11:37 PM

We have an issue even with document currency in USD. there is a valuation difference between Local currency (USD) and Group currency (USD).
For example:
Doc currency = 0 USD
Local Currrency = 171,000 USD
Group currency = 0 USD
Because of this I am not able to clear the account. Not sure why there is a difference inspite of the same currency. I try to clear it in F-04 but I get the below error:
Posting is only possible with a zero balance; correct document

Differences between clear() & removeallelements() in vectors

Hi, I just want to clarify, whats the difference between clear() and removeallelements() in vectors?
according to the apis,
clear()
Removes all of the elements from this Vector.
removeAllElements()
Removes all components from this vector and sets its size to zero.
So does it means that clear() do not reset it to zero? for what I understand and tried out, clear(0 does reset to zero as well unless I am wrong, please explain the above and if appropriate, give examples in laymana terms..
thanks in advance.

Quoting the source of Vector.java:
     * Removes all of the elements from this Vector. The Vector will
     * be empty after this call returns (unless it throws an exception).
     * @since 1.2
    public void clear() {
        removeAllElements();
    }As you can see, the clear-method was added later when Vector was re-written to fit into the Collection API's

PE2 - What's the difference between "cut" and "clear" in Project Assets?

When removing items from the Project Assets area, what's the difference between "cut" and "clear"?
Also I believe "delete" is an option at times, but I couldn't replicate it.

Cut should Delete, but transfer that Clip to the Clipboard, where Clear will just Delete it completely - no transfer to Clipboard.
That can be tested by doing a Cut, then move the CTI (Current Timeline Indicator) to the end of the Timeline, and hit Ctrl+V (Paste). That Deleted Clip should appear after the CTI.
Then, clear (or choose a different Clip) the Clipboard, and try Clear. It should not Paste the Clip into the Timeline.
Good luck,
Hunt

What's the difference between keep cookies until I close firefox and clear cookie history when firefox closes?

In the settings for Firefox 33.0 (I am using Ubuntu 14.04 but the functionality is the same for Windows 7) there are two different ways to delete cookies when firefox closes. Or at least there seems to be.
First is the keep cookies until firefox closes
Second is to check the box to clear history when firefox closes and in the settings check cookies.
What is the difference between these two options?
I usually have both setup but I was noticing that a login was not saving for td canada trust easyweb, even though I have an exception set for it. Now I unchecked to delete cookies when clearing the history on close and the login saves correctly.
This login saves 7 cookes under easyweb.td.com and 10 cookies under td.com and I have exceptions set for both. If I clear history on close and include cookies, half of the td.com cookies are gone when I close firefox and re-open. The same is true if I don't set the exception.
So currently I cannot figure out a way to keep all the cookies if I clear cookie history when firefox closes. What is the difference when this is enabled?

Let all cookies expire when Firefox is closed to make them session cookies.
*Firefox/Tools > Options > Privacy > "Use custom settings for history" > Cookies: Keep until: "I close Firefox"
Create a cookie 'allow' exception for cookies that you would like to keep.
*Firefox/Tools > Options > Privacy > "Use custom settings for history" > Cookies: Exceptions
Clearing "Site Preferences" clears all exceptions for cookies, images, pop-up windows, software installation, passwords, and other website specific data.
Clearing cookies will remove all specified (selected) cookies including cookies with an allow exception that you would like to keep.
*Tools > Options > Privacy > Firefox will: "Use custom settings for history": [X] "Clear history when Firefox closes" > Settings

Difference between list.clear() and new instance

In the below code,
List<String> test = new ArrayList<String)();
list.add("one");
list.add("two");
list.add("three");
list.clear();
(or)
list = new ArrayList<String)();
list.add("four");
list.add("five");
What is the difference between List.clear() and creating new instance for list?

1. Use code tags to post codes -- [code]CODE[/code] will display asCODEOr click the CODE button and paste your code between the {code} tags that appear.
2. Invoking clear() sets all the elements of the ArrayList to null and resets the size to 0. public void clear() {
 modCount++;
 // Let gc do its work
 for (int i = 0; i < size; i++)
 elementData[i] = null;
 size = 0;
 }(modCount is used to detect concurrent modification and throw an Exception when needed)
Constructing a new ArrayList creates a new, different, empty ArrayList.
In many situations they might be equivalent, but not in a case where you have two or more variable references to the same ArrayList. Example (watch out for typos)ArrayList<String> stringsA = new ArrayList<String>();
ArrayList<String> stringsB = stringsA;
: // add elements to stringsA
: // stringsB refers to the same populated list
stringsA.clear(); // stringsB refers to the clear()ed list
: // add elements to stringsA again
stringsA = new ArrayList<String>(); // stringsB still refers to the populated listdb

Differences between clear case 23' and new 23'

I am having a hard time finding the differences between the two monitors. my clear case 23' is about 2 years old.

Hi Matt,
First off, KEEP your older ADC display. They have much more natural color
and don't suffer from the pinkness and blue banding on the new Aluminum.
I have followed the discussions since August of last year and there is no
end to the color consistency complaints. In fact, Apple has deleted over 1000 messages regarding this. Why? Hmmm. They threw out a lot of helpful
hints that could have helped their customers.
I personally bought and returned 7 Alum Cinema 23 displays. Some from Apple, some from Fry's, and others from UCLA Apple store.
The case is a beautiful design but the interior is different than the old 23.
The new ones are brighter, more saturated in color and have 2 Firewire and
2 USB ports available.
However, they got rid of the system/start up power button and added a power brick with cables waving all over the place.
I hopoed they would have solved the production problem by now but it seems
that too few people are complaining ( graphic designers/video editors ).
I gave up and just bought a one year old Plastic 23 display for $1000.
I love it. The only thing I don't like is that the whites are a little yellowish
due to its lower brightness specs ( 230 nits vs. 270 nits on the new one.
The way to see the color issues with an Alum model is to set the desktop to
a neutral gray. Or, simply drag a small image of gray (perhaps open up the little gray jpg located in Library/Desktop Pictures/Solids) across the screen.
The left side will look a little pink and it will change to a blueish tone as you move to the right.
Or better yet, open the Apple display calibrator, look at the Apple icon and
move the window to the extreme left and right.
It is only visible clearly in these circumstances but most people don't care.
Considering the price drops it might be nice to get a new one but all I
know is all the motion graphics studios I work at use the old monitors.
It also is no coincidence that this past weekend Apple sold out of refurbished
Plastic Cinema 23 in 24 hrs, while the Alum refurbs just sat.
Take a look at the specials. They always have something good.
Good luck to you. Hopefully, I won't be deleted for voicing my opinions.
I'm a diehard Mac user and really this Alum 23 monitor is the first thing I
ever complained about.

Ghost Armor vs. Invisible Shield

Searched for this already but no one here has mentioned much about Ghost Armor on their 3G's. Did a google search and a lot of people said Ghost Armor was good.. but that's what they said about IS and I was ****** off about invisible shield's kinks (like the edges not fully sticking for the back piece, and the thin multicolored lines on the front which are not covered under the IS warranty)
Anyone have opinions?

ok, i'm still trying to get my photos of my comparison on my pc and then to my picasa act, in the mean time here are some phtots I have found

Difference between Simple, EPC Gen 1 & EPC Gen 2 tags?

Hi All,
1. Can some one explain me the difference between Simple, EPC Gen 1 & EPC Gen 2 tags?
2. When are they used?
3. Which is the one, widely used?
Thanks,
Shridhar..

Hi Shridhar,
Actually earlier I only mentioned the main difference between the two that was the Q Algorithm and mentioned some links which would help you to get some more differences.
From your reply I thought should make more easier for you.I have segregated some differences for you from those Links .
Difference between GEN1 and GEN2 tags.
New features that were incorporated in the Gen 2 protocol.
1.The biggest difference between Gen 1 and Gen 2 is that there is now a single global protocol. The first-generation epc had two protocols, Class 0 and Class 1, and the same reader could not read both unless it was a multiprotocol reader. The International Organization for Standardization (iso) also approved two uhf air-interface protocols, 18000-6A and 18000-6B, as international standards, so there have been four uhf standards.

2. Another important aspect of the UHF Gen 2 protocol is it was designed to optimize performance in different regulatory environments around the world.
 Europes communications authoritiesrecently adopted reader regulations that are more relaxed, but the new rules are still quite stringent compared with those in the North America. Because the Gen 2 protocol uses the available radio spectrum more efficiently, it will provide better performance in Europe than any other uhf protocol. Gen2 creates a good foundation for higher-function products, such as Class 2 and Class 3 tags and readers.
3. Dense-reader mode
The Gen 2 standard allows readers to operate in three different modes: Single-reader mode, multi-reader mode and dense-reader mode. To function optimally, readers will need to operate in
dense-reader mode when more than 50 readers are present within a building, such as within a distribution center. Dense reader mode is designed to prevent readers from interfering with
one another, which could be a problem if many readers are used in a confined space, particularly in Europe and other regions where only a small band of the uhf spectrum has been allotted
for rfid systems.
4. Dual methods of backscatter encoding
The Gen 2 protocol also supports another method of encoding the backscatter signal called FMO. The purpose of allowing the reader to use either FMO or Miller subcarrier was to improve
performance not just when there are many readers in a facility but also when there is a lot of noise in the area.
FMO, a format used effectively in the current ISO standards, is fast but susceptible to interference. Miller subcarrier is slower but works better in noisy environments.
5. Secure read-write memory
First-generation EPC Class 0 tags are programmed at the factory, when the chips are made. First-generation Class 1 tags are user programmable, meaning that an end user company can write EPCs to the tag after taking delivery. In most applications today, Class 1 tags are programmed one by one as they come off a spool.
Gen 2 tags are field programmable, meaning that readers can write information to tags even if they are attached to cases on a pallet or a conveyer belt. Gen 2 tags will feature three required memory banksone bank for storing the epc, one for passwords, one for tag identification (the tag stores information about itself)and an optional bank for memory that end users can use for whatever purpose they wish (one of the few optional features tags can have). User memory could be to store codes to indicate where products are being shipped to, for instance.
The memory banks can be locked temporarily or permanently.So a product supplier might write an epc to a tag and lock it permanently. It might then write the identification number of a store that the product is being shipped to in the optional user memory. The supplier might lock that memory with a password to avoid having it overwritten, but a manager in the stores distribution center might have the option of unlocking the memory (if the manufacturer supplies the password), changing the store id to indicate the destination has changed, and then locking the memory again.
6. The Q algorithm
One issue with the Gen 1 protocols is that they require rfid readers to use the tags unique serial numbers to singulate tags (to identify them uniquely). If two tags have the same epc, they confuse the reader. Some retailers are considering using tags with the same epcthat is, information similar to what they have on bar codes todayas an interim measure as they move from bar codes to rfid and prepare their software systems to handle unique ids. Those retailers asked EPCglobal's Hardware Action Group to make it possible to singulate the tags even if two or
more tags have the exact same epc.
This Algorithm is mentioned in my first reply above.
7. Sessions
One weakness of the Gen1 protocols was the possibility that one reader would interfere with another reader's ongoing counting of a group of tags. So let's say a fixed reader is counting all the tagged items on a shelf. It reads a tag and commands it to go to sleep so it can read the next tag.When it is halfway through 100 items, someone comes along with a handheld reader, looking for a specific item on that shelf. The handheld commands all the tags to wake up and respond. Now the fixed reader has to start the counting all over again. To avoid this problem, the Gen 2 protocol introduces something called sessions. Each tag will be able to operate within four
separate sessions. A retailer or manufacturer could set up their system so that all fixed readers read tags in session 1, and all handhelds use session 2. So if the fixed reader puts the tags to
sleep in session 1, the handheld reader could communicate with the tags in session 2 and not interfere with the ongoing count by the fixed reader in session 1.
Enhancements made to the Gen 1 protocols.

1.Faster read rates:
The Gen 2 protocol is designed to enable readers to read data from and write data to rfid tags much faster than the Gen 1 protocols. Gen 2 supports a tag-to-reader data transfer rate of up
to 640 kilobits per second, versus up to 80 kilobits per second for Gen 1 Class 0 and 140 kilobits per second for Gen 1 Class 1.
2. Fewer ghost reads
One problem early adopters have encountered with the Gen 1 Class 0 protocol is ghost reads. Sometimes the reader thinks it has read a tag with a particular Id when no tag with that id is present.
3. Longer passwords.
Now to talk about your queries.
>>Q's:1. What if the Tag ID is alpha-numeric?
let me know from which link you read this so that I can comment on it.(If i missed it).
>>Gen 2:These type of Tags have the ability to generate random numbers. The reader asks the tag to generate random numbers.
Q's:1. What is the match/criteria upon which Tag/s respond to the reader with the EPC, after which the reader can continue the flow.
Now if you again go through the Q Algorithm mentioned in my above reply.This query is answered.
Well I again mention the part of the Algorithm
 " Gen 2 tags have the ability to generate random numbers. The reader will tell the tags the range in which it should generate a random number by issuing a query command with a Q value ranging from 0 to 15. If it often gets back no response to its queries, it will automatically decrease the Q value. If it gets more than one tag responding, it will increase the Q value, thereby increasing the range of numbers that can be generated by the tags. The reader might issue a query with a parameter of Q=4. The tags generate two random numbers, the first one ranging from zero and 65,535, and the second ranging from zero and 2 to the power of Q, minus 1. If Q is four, then 2 to the fourth power is 16, minus 1 equals 15. So all tags choose a second random number ranging from zero and 15. The reader asks any tag that chose zero for their second random number to respond. If one tag has zero, then it responds with the first random number, between zero and 65,535, and the reader acknowledges it. Since the tag has now been singulated,the reader could simply count the tag as present ("I know a tag with a random number of 45,101 is in the field"). It could write an epc to the tag, if it doesn't have one, or it could ask tag 45,101 for its epc if it does have one. It then asks the remaining tags to subtract one from their second random number and singulates the next tag that has a zero, and it keeps doing that until all the tags are singulated. If no tags choose zero for their first random number, then the reader asks all the tags to decrement their random number by one, and it keeps doing that until a tag with zero responds. If two tags respond, the reader can't read either tag, so it issues a negative acknowledge, which tells the tags to wait for another query until they respond again. "This protocol makes it extremely unlikely that a reader will singulate two tags when it meant to only talk to one" . "
The above mentioned is the match/criteria upon which Tag/s respond to the reader with the EPC, after which the reader can continue the flow.
I suppose this should clear all your doubts.Let me know if still there are any.
Thanks,
Pawan

Difference between Item categories M and W

What is the difference between the Item Categories ' M ' and ' W ' ?. When & where these item categories are used?

HI,
The item categories M and W are intended for the entry of contract items without
specification of the material number.
Item category M
Recommended for similar materials of the same price. These can be materials with
different material numbers or materials without material master records.
You have set up a contract with your vendor covering various types of writing
paper (lined, squared, blank, two-/four-hole prepunched, etc.). The different types
of paper have the same weight, the same quality, and the same price.
When entering this contract item of category M, you enter the short description,
material group, target quantity, unit of measure, and price, but no material number.
The short description must then be entered in the contract release order (for
example, lined, two-hole prepunched).
You also have the option of releasing materials with a material master record
against this contract item in the release order, provided that the material group and
purchase order unit of measure agree.
Item category W
Recommended for materials belonging to the same material group but with
different prices. Item category W can only be used in value contracts.
You have set up a contract with your vendor for various types of cable. The
contract is to cover all types of cable included in the vendor's price list. However,
the exact type is only determined when a purchase order is created for a certain
cable. Instead of creating one contract item for each type of cable in the vendor's
assortment, you could enter item category W and the appropriate material group
(for example, cable). From the short text, it would then be clear that the contract
item covers all types of cable supplied by the vendor in question. Each release
order issued against this contract would then contain the exact specification of
cable type and quantity (for example, double-shielded coax, 1 meter), and price.
When entering the contract item, you enter only the short text and the material
group. You do not enter the target quantity or price. It is possible to enter
additional conditions. For example, you can enter a discount in the header
conditions if the vendor grants a discount on all POs referencing the contract. The
discount is calculated automatically when a contract release order is created.
The price, the target quantity, and the material number are not specified until you
create a release order. The relevant material master record must be assigned to
the same material group as the contract item referenced. If the contract release
order does not contain a material number, it must have a valid account assignment
(such as a cost center).

Difference between GUI_UPLOAD and WS_UPLOAD

Hi,
Please make me clear about the difference between GUI_UPLOAD and WS_UPLOAD. In which cases we need to use these modules...??
Thanks,
Satish

I would suggest to always use the GUI_UPLOAD. I say this because this is the function module which is used in the GUI_UPLOAD method of the class CL_GUI_FRONTEND_SERVICES.   Really, you should probably use the class/method instead of the function module.
data: filename type string.
filename = p_file.
call method cl_gui_frontend_services=>gui_upload
         exporting
              filename                = filename

              file_read_error         = 2
              no_batch                = 3
              gui_refuse_filetransfer = 4
              no_authority            = 6
              unknown_error           = 7
              bad_data_format         = 8
              unknown_dp_error        = 12
              access_denied           = 13
              others                  = 17.
