What exactly is the difference between these two lenses?
CanonEF-S 55-250mm f/4-5.6 IS STM Lens
CanonEF-S 55-250mm f/4-5.6 IS II Lens
I'm stuck between a rock, and not sure what my best option would be...any help is greatly appreciated!!!
The difference is in the type of motor used to focus the lens. The focus motor in STM lenses are more or less silent to the camera's audio system. This is important when shooting video but not for still photography. This may help.

What is is the difference between these two command that enable Multicast?
I see that both get used frequently. My WLC does not seem to support the top one:
config network ap-mcast-mode multicast 239.239.239.239
config network multicast mode multicast 239.239.239.239
ThanksYes, first one may be a old command in previous WLC code versions. No longer supported in newer codes.
You only require 2nd command to configure a multicast group for WLC to use for CAPWAP multicast for APs.

Whats the difference between these two queries ? - for tuning purpose
Whats the difference between these two queries ?
I have huge amount of data for each table. its takeing such a long time (>5-6hrs).
here whice one is fast / do we have any other option there apart from listed here....
QUERY 1:
SELECT --<< USING INDEX >>
field1, field2, field3, sum( case when field4 in (1,2) then 1 when field4 in (3,4) then -1 else 0 end)
FROM
tab1 inner join tab2 on condition1 inner join tab3 on condition2 inner join tab4 on conditon3
WHERE
condition4..10 and
GROUP BY
field1, field2,field3
HAVING
sum( case when field4 in (1,2) then 1 when field4 in (3,4) then -1 else 0 end) <> 0;
QUERY 2:
SELECT --<< USING INDEX >>
field1, field2, field3, sum( decode(field4, 1, 1, 2, 1, 3, -1, 4, -1 ,0))
FROM
tab1, tab2, tab3, tab4
WHERE
condition1 and
condition2 and
condition3 and
condition4..10
GROUP BY
field1, field2,field3
HAVING
sum( decode(field4, 1, 1, 2, 1, 3, -1, 4, -1 ,0)) <> 0;
[pre]My feeling here is that simply changing join syntax and case vs decode issues is not going to give any significant improvement in performance, and as Tubby points out, there is not a lot to go on. I think you are going to have to investigate things along the line of parallel query and index vs full table scans as well any number of performance tuning methods before you will see any significant gains. I would start with the Performance Manual as a start and then follow that up with the hard yards of query plans and stats.
Alternatively, you could just set the gofast parameter to TRUE and everything will be all right.

What is the difference between these two sticks of RAM?

What is the difference between these two kits?
4GB Kit (2 x 2GB) 200 Pin DDR2-667 PC2-5300 256x64 CL5 1.8V SODIMM ($102.00)
4GB Kit (2 x 2GB) eRam 200 Pin DDR2-667 PC2-5300 CL5 1.8V SODIMM ($88.00)Probably nothing of any consequence. Some places can just negotiate better deals with suppliers. Or one of a million other factors that can affect price is in play here.
When buying RAM, I generally find it's better to pay a little extra to get a brand that's known for quality. I usually stick to Crucial myself. If you look around, you can probably find some real steals out there, but I don't know... With stories of people who literally go dumpster diving, salvaging stuff that was slated for disposal, then turning around and selling it... I prefer not to take chances. If you are, by all means, go for the cheaper one. -
What is the difference between these two portalapps folders on the Server?
Hello,
On the Server there are two portalapps folder:
1. Under: C:\usr\sap\JXX\JC00\j2ee\cluster\server0\apps\sap.com\irj\servlet_jsp\irj\root\portalapps
2. Under: C:\usr\sap\JXX\JC00\j2ee\cluster\server0\apps\sap.com\irj\servlet_jsp\irj\root\WEB-INF\portal\portalapps
Can someone please explain me what is the difference between these two portalapps folders and under which case will I turn to which folder?Hi Roy,
The one at this location
Under: C:\usr\sap\JXX\JC00\j2ee\cluster\server0\apps\sap.com\irj\servlet_jsp\irj\root\portalapps
has all the files from the WEB-INF folder i.e. these are the non-web resources and cannot be accessed via HTTP(S) examples would be imgaes, CSS etc that you want only your application to access
those under
Under: C:\usr\sap\JXX\JC00\j2ee\cluster\server0\apps\sap.com\irj\servlet_jsp\irj\root\WEB-INF\portal\portalapps
they have all the .JAR files, portalapp.xml, config properties etc. these are web resources and can be accessed via HTTP(S)
Hope this is of help.

What is the Difference between these Two?
Hi All,
In Oracle University site i saw 2 Courses for Oracle Webcenter sites. Just i would like to know the difference between these two. Based on your input i can decide which one to take.
*1. Oracle Webcenter Sites for Developers*
http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=609&p_org_id=1001&lang=US&get_params=dc:D73886GC10,p_preview:N
*2. Oracle Webcenter Sites 11g for Developers*
http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=609&p_org_id=1001&lang=US&get_params=dc:D78300GC10,p_preview:N
Is the 1st one is Fatwire and the 2nd one is Fatwire+Oracle latest implmentation ? Is my understanding is right?
regards
SriIt's the same lens, just different sellers. The higher one is the MSRP, or close to it. But since they use this lens in a kit it goes for less. I have no idea who Celltime Inc is, but it's fullfilled by Amazon, so I'd feel reasonably safe. Just look into their return policy.
With the recent release of the 6D and somewhat recent 5d3, the market is flooded with these lenses from kits; I wouldn't pay more than 800 something for it. Getting it through Amazon is a bonus over eBay. If the seller checks out I'd go for it.
Edit: DH beat me to it. -
What's the difference between these two networks?
Have searched a lot but can not find a clear answer to the difference between these two networks.
(I'm using these as examples only)
Using Airport utility
* sometimes theres a dotted line "......"
*And sometimes there's a solid line like a " } "
I chose these as an example because ours is just like the first example above.
However sometimes our presents similar to the above example only with two devices, not three.Dotted line is wireless.. Solid line is ethernet..
Normally all ethernet should show as your lower picture since all are directly wired..
Wireless should show which Airport is the main base and which extend using wireless.
But it is 50% science and 80% voodoo (voodoo cannot count even!!) -
What exactly is the difference between enqueue,latch & lock
Can someone explain in simple words (with example if possible) what exactly is the difference between enqueue,latch & lock?
I have gone through documentation & other links,but just not able to figure out the exact & clear difference between these three..
Cheers,
KunwarIn addition to links provided by Sb and nice explanations by Aman, i would like to add below :
1.Latches and enqueues are lightweight serialization devices used to coordinate multi-user access to
shared data structures, objects and files.
Latches are locks that are held for extremely short periods of time, for example the time it takes to modify
an in-memory data structure. They are used to protect certain memory structures, such as the database
block buffer cache or the library cache in the shared pool (as described in Chapter 2, Architecture). Latches
are typically requested internally in a ‘willing to wait’ mode. This means that if the latch is not available,
the requesting session will sleep for a short period of time and retry the operation later. Other latches may
be requested in an ‘immediate’ mode, meaning that the process will go do something else rather than sit
and wait for the latch to become available. Since many requestors may be waiting for a latch at the same
time, you may see some processes waiting longer than others. Latches are assigned rather randomly, based
on the ‘luck of the draw’, if you will. Whichever session asks for a latch right after it was released will get it.
There is no line of latch waiters, just a ‘mob’ of waiters constantly retrying.
Oracle uses atomic instructions like ‘test and set’ for operating on latches. Since the instructions to set
and free latches are atomic, the operating system itself guarantees that only one process gets it. Since it
is only one instruction, it can be quite fast. Latches are held for short periods of time and provide a
mechanism for clean-up in case a latch holder ‘dies’ abnormally while holding it. This cleaning up
process would be performed by PMON.
Enqueues are another, more sophisticated, serialization device, used when updating rows in a database
table, fro example. They differ from latches in that they allow the requestor to ‘queue up’ and wait for
the resource. With a latch request, the requestor is told right away whether they got the latch or not.
With an enqueue, the requestor will be blocked until they actually attain it. As such, they are not as fast
as a latch can be, but they do provided functionality over and above that which a latch can offer.
Enqueues may be obtained at various levels, so you can have many ‘share’ locks and locks with various
degrees of ‘shareability’.

What is the difference between these two instant ink printers?
Looking to get one of the HP instant ink printers from Best Buy. Either the Envy 4500 or the Envy 5530. There is a $20 diference and I did a side-by-side comparison of them on the Best Buy site, but the only difference I can notice is the 5530 seems to have more memory than the 4500 (128MB vs 32MB).
Print speeds and resolutions seem to be the same. The cheaper one (4500) also seems to be able to do two-sided printing & reduction/enlargement (which I would have thought to be on the more expensive mode). So are there any other real differences between these two or have I pretty much covered them all?HI - great question, you identified a few of the differences. Some additional differences are:
4500 has a monochome display that is not touch enabled (you have to use scroll buttons on the side of the screen)
5300 has a touch enabled color display
Both printers can do duplexing (printing on both sides) and both have wireless.
We are excited about Instant Ink and hope you enjoy the service & whichever printer you chose!

Would you happen to know the difference between these two fields from FI-GL
Hi,
Would you happen to know the differnce between these two field
i. UMSOL from 0fi gl6 and DMSOL from 0fi_ gl_4
ii. UMHAB from 0fi gl6 and DMHAB from 0fi_ gl_4
iii.In a test case on a system, where I was looking for the same values in comparison, I am getting inconsistent data.
which key figures in 0fi gl6 are equivalent to which in 0fi_ gl_4
Any hints
Thnx
Edited by: AmandaBaah on Jul 29, 2009 2:47 AMHi Amanda,
They are both very different datasources. 0FI_GL_6 is the General Ledger: Transaction Figures which fetched data from the GLT0 table while 0FI_GL_4 fetched data from the BSEG and BKPF tables and fetched the line items from the general ledger.
You can refer the following links for more info

What's the difference between these two backup systems?
When I bought my Macbook Pro I bought a Seagate external HD that used Bounceback Express as its backup application. But now my Mac defaults to Time Machine. What's the difference between the two applications? When I use Time Machine to back up my hard drive to the Seagate external, is it doing the same thing as Bounceback Express used to?
In analog terms, to explain YCbCr use the example of the COMPONENT output from your DVD player. It use 3 separate cables (Y = Luminance = Green Cable), (Y-B = Blue Color Diff = BLUE Cable) and (Y-R = Red Color Diff = RED Cable). In the analog world, RGB is actually RGBHV (5-wire) and is adaptable to 15-pin VGA with a simple passive adapter. Many people will mistakenly refer to Analog Component video as RGB, since the cables are Red, Green and Blue.
So, since all that mumbo jumbo means essentially the same, this appears to be the digital "equivalent" of what is known as Component Video in the Analog world... What I said about RGBHV does not apply to the 10-bit color, but thought I'd mention it anyway.
