Which DVDs are good for storing projects.

I tried to burn a family video project (iDVD) on a blank (newly purchased) Verbatim DVD-R (MCC03RG20 discs made by Mitsubishi Chemicals and branded for Verbatim). This is the message I got: "Unable to burn project. (The device failed to calibrate the laser power level for this media.)"
Then I could burn the same project on a plain Sony DVD-R. And it worked.
I am trying to burn my family movies on good quality disk that is why I bought the Verbatim disks. But it seems they are not good???? Please help!!!
I also burn 1 copy of my projects on Verbatim Gold Archive DVD-Rs for long term storage. These are burning as well.
What is wrong with my "plain" Verbatim disks. I want to use these for every day viewing so my kids can load them in the player, lose them etc. That is why I bought these cheaper versions for the everyday use.
Thank you so much for any advise,
Ildiko

So I assume nothing wrong with my plain Verbatim but maybe my Superdrive is dirty. But why would it burn other brand DVDs?
Taiyo Yuden DVDs have a 100-year data integrity guarantee. Made in Japan, not China.
I have found DVD+R to be more reliable than DVD-R. The only disadvantage to DVD+R is that DVD players manufacture before 2003 may not play them.
DVD+R disks are better than DVD-R disks because of the increased error correction technique used for the newer +R type.
I would recommend Taiyo Yuden DVD+Rs. I get excellent results using iMovie 06 with iDVD 09, (and sometimes iMovie 09).
This may be the best media if money is no object.

Which DVD are good for burning

I tried many different dvd/cd for burning movies and music, but they are not all working very well.
Does somebody knows which dvd are good for burning movies and music.

Hi Sue,
Thanks for your answer. I bought them also before, but it seems that not all working very good.
I burned dvd's and play them on my Home theather. Beginning good, later it gave reading problems. What I also know is: Dvd players from 40 euro's works better then one from 1600 euro's.
I shall buy the -R this week and hopefully the work better.

Which headphones are good for gaming ?

i am thinking of buying gaming headphones . which ones are the best for a macbook pro ?

If you want to do any serious gaming, get a desktop PC. Preferrably build your own (saves a lot of money).
Alienware laptops are over-priced and over-hyped. For that much money, you could build a beast gaming rig.
There are some tutorials online by this awesome guy that should help you get started!

Vector (good for storing) and arrays(good for numerical sums, multiplying)

Hi guys, I am trying to use vectors because I need a variable lenght and store 2D arrays in one coordenate of a vector. That is why I am using vector instead arrays. I can turn the type of variable using "Integer" (instead of "int" as arrays), "Double" (instead of "double") and so on. The problem is that it doesn't allow me to operate, it is very good for storing, but I need to be able to operate, multiplying, sum, etc the elements there are in the coordenates. And I think it is not possible.
What u think about it? I can only store stuff ion a vector, I cannot operate. Besides I cant turn a data from "Double" to "double", I can either use arrays OR vectors, but not both of them at the same time.
You think i am wrong?, because I mean in that case, Java is not very useful to do this numerical problem.
Thanks.
This is only a class of the program I am doing.

The only way to, for instance, multiply a Double object by another Double object is to convert them back to primitives, multiply them, and create a new Double instance:
public Double multiply(Double lhs, Double rhs) {
   return new Double( lhs.doubleValue() * rhs.doubleValue() );
}This is just an overhead that you have to accept if you want to use collections with primitive type data.
Coming soon in 1.5 (which is in Beta now and available for download in the usual places) a new feature called auto-boxing will do a lot of this automatically for you. You need to be aware that it's doing exactly the same operations with the same performance overhead; but it does save a lot of typing.
Thus in 1.5 the above becomes:
public Double multiply(Double lhs, Double rhs) {
   // Under the hood this is IDENTICAL to the above example
   return lhs * rhs;
}Now, addressing your post directly:
Besides I cant turn a data from "Double" to "double"
Yes you can, as in the first example, the doubleValue() method converts a Double object to a double primitive.
Java is not very useful to do this numerical problem.
If you need math performance, you need to use primitives, yes. Yes, that will preclude the use of collections.

The retina display MacBook Pros are very lightweight, so you won't really notice a weight difference between a 15" or 13" one. If you can afford it, get the 15" notebook.
Purchase the most powerful configuration you can afford. If you can afford it, get the larger SSD - but, you can always get a portable external hard drive that you can take with you if you find the internal drive is too small.

Like I said before ask facebook or look at their support site to see if that is even a feature.

Edge and Next are good for the corporations but are they good for the consumer?

Ok so I have never paid full price upfront for a phone! Ever since my first phone from VoiceStream I have opted for what ever phone was "free" because way back then (I blush as I type) I actually thought the phone was "free!!!" Ah, to be naive again!! But as we all know the phones never were nor will they ever be free.
However I say programs like Verizon's Edge and AT&T's Next are good for the corporation if they weren't they would not exist. The first reason I say this is because Edge and Next allow the cellular service provider to easily recoup the entire cost of the phone in a clear way unlike with subsidized phones that muddy the profit water. For example, the Verizon 64GB iPhone 5s retails for $849.99, currently with a two year contract you pay $399.99 for that 64GB iPhone 5s. The EFT for that phone is $350 (minus $10 per month of post paid service). If you on the 15th the day after you got your phone you paid the EFT but kept service you only paid $749.99 for that $849.99. Sure you still pay for service but you can leave when ever and Verizon cannot say hey you owe us $100 more for you phone. Its yours and they can't take it back and the only way Verizon will get that $100 back is though another customer that subsidized a much lower cost phone that at the completion of that contract Verizon will more than recoup the cost of that lower priced unit. To top that off you could turn around and sell the phone for $800 go back to Verizon or another provider buy a $450 phone and break even. I'm not suggesting that people do that or that it may prove to be a big hassle for some that went through all the trouble. Its just a point to show that subsidized phones make the profits less clear for the service provider to see at first glance.
Second reason these programs are good for the corporation is they allow the service providers to get a better grasp on the true cost of maintaining their networks and providing us the consumer access to their networks. Third reason it good for the corporation is the people that feel the need to upgrade every six months to a year are required to pay at least 50% of the retail cost of the phone at the same time they must surrender that device in exchange for the new device. So the service provider then has the phone refurbished certified to be in "like new condition" and sell it again potentially making more than retail cost when the profits of both sales of the same handset are factored together.
That being said what will the impact of programs like Edge and Next have on cost of future cellular service plans and smartphones? Over time will the service provider give us the best per line access fee (not likely but maybe)? Or will people upgrading their smartphones at faster intervals cause the cost of the smartphones to drop over time? What are your thoughts?

Which archivelogs are required for restoring database

I'm moving to RMAN direct to tape backups (via Netbackup). I'm hoping someone can clarify for me which archivelogs are needed for restoring/recovering a RMAN "hot" backup.
I will have two tape pools with different retention periods:
- standard (kept for 2 months)
- long term (kept for 7 years)
I plan to backup as follows:
- archivelogs every 15 mins direct to the standard pool
- daily backups to the standard pool
- monthend backups to the long term pool
Month ends will either be a full or a full plus a cumulative (level 2) (depending on the weekday that month end falls on).
The bit I'm concerned about is archivelogs. After 2 months they will be expired on tape. But do I need archive logs in order to restore the month end backups?
At the moment I record the SCN before the backup begins and after it finishes (retrieved via select first_change# first_scn from v$log where status = 'CURRENT'). Before recording the post-backup SCN, I force a logfile switch.
For clones, I always restore to the post-backup SCN that I previously recorded (rather than using the tag I associated with the backup).
So a few questions related to restoring after the 2 month window:
- do I need the archivelogs created during the timespan of the backup ran in order to restore to the post-backup SCN?
- If so, is just backing up these archivelogs (to the long term pool) by specifying the range of pre-backup SCN to post-backup SCN sufficient or are additional archivelogs likely to be required?
- if I restore the database and don't specify an SCN but just specify the tag used at the time of the backup, will archive logs be required at all? In this case what would be the state of the restored database - would it be as it was at the beginning or at the end of the backup?

Hi user4835675,
do I need the archivelogs created during the timespan of the backup ran in order to restore to the post-backup SCN?Yes.
If so, is just backing up these archivelogs (to the long term pool) by specifying the range of pre-backup SCN to post-backup SCN sufficient or are additional
archivelogs likely to be required?Can you do a skip of the daily backup schedule duing the monthend backups run and run the "archivelogs every 15 mins" job to the long term pool?
Or temporarily stop the "archivelogs every 15 mins" job during the monthend job and run the monthend backup with the "backup database plus archivelog" clause?
if I restore the database and don't specify an SCN but just specify the tag used at the time of the backup, will archive logs be required at all?Yes, you need archivelogs to recover the datafiles to a consistent state.
In this case what would be the state of the restored database - would it be as it was at the beginning or at the end of the backup?You can only restore to a point in time which past the end of the backup.

After this you will have the Mac App Store on your MacBook and you should be able to download and install OS X Mavericks for free!

Which upgrades are relevant for me?

Hi all.
I am going to order the new iMac 21,5" 2.9 GHz and I need some help figuring out which upgrades are relevant for me.
I am going to use the iMac for the following:
- Webdesign (my profession)
- Photoshop and perhaps other Adobe applications
- Lots and lots of multitasking and many tabs in browsers
- Screen Flow application (screen recording software)
- Dual boot with Windows 7
- Time Capsule backups
- Gaming (Sims 3 primarily - in Windows 7)
I want it to be "future proof", but since hyperthreading isn't widely used in applications yet and people write that the majority of people never go beyond 4GB of RAM i'm onsure whether I should upgrade the CPU and RAM.
Also, since the iMac 21,5" is not user-upgradeable after you get it, I want to make sure that I don't end up having a slow computer that I wish I would have made better/faster. I just want it to function fast and smooth. Today I have a MBP 15" medio 2009, 2.66 Ghz Intel Core 2 Duo, 4GB RAM, which I think performs overall well but is a bit slow sometimes.
The only upgrade I seem sure of for now is the 1TB Fusion Drive.
Thanks in advance!

Although I am sure you have seen all this ... this is the formal description of that machine. Apple (United Kingdom) - iMac - Technical Specifications
I cannot answer you questions about the specific tasks you plan to use it for; they are simply outside of my knowledge base, but you do raise points about being 'future proof', as you describe it, and I am afraid Apple is no more future proof than any other computer. It is a fact that the sales of Apple machines rely on upgrading at periodic intervals, often using upgrades that were designed and known about two years before. That, I'm afraid, is business.
As far as the RAM is concerned you will have to decide between 8 GB and 16 GB when you order it as it cannot be RAM increased afterwards. (The 27" can, I understand.
Very much based on talk within the forums but I hope this is of some help to you.

Which tables are used for Quality Efficiency calculation of OEE report ?

Hello,
We're confirming OEE report behavior.
I'd like to know OEE report and ME table specification.
Which tables are used for Quality Efficiency calculation of OEE report ?
According to I know, the definition of Quality Efficiency is (complete qty) / (start qty).
For this calculation, does OEE report just use qty_started and qty_completed of PRODUCTION_LOG table?
If any other tables/columns/logic are implemented, your information is appreciated.
