Random seed for the grain in lightroom?

Is it possible to get a random seed for the grain in lightroom when applying to multiple images? I really like the grain in lightroom and would like to use it for an image sequence, so its really important that the grain changes from frame to frame.

Yeah. I just exported a set of over 7000 images to import them in premiere as sequence. The grain stays in the exact same pattern throughout the 2 minutes of video so that it looks not like (dynamic) film grain but like a static curtain.

Firefox has been crashing at random times for the last two days

Firefox has been crashing randomly for the last two days. I had to download Malwarebytes yesterday because I picked up Malware Doctor (I think that's the name.) It was soon after I had removed the spyware that Firefox started crashing.

Grabbing Random Questions for the Question Pool

Hi Everyone,
I am interested in exactly how the Random Question Pool
works. Let's say there are 50 questions in the question pool and
you want 10 questions from that question pool of 50. When you
publish I understand you will get 10 random questions from the 50
questions. Then when you run your published project are you always
going to get the same 10 questions or another 10 of the 50 pooled
questions everytime your run that same published project? Or do you
have to publish again, calling the quiz another name to get another
10 of 50 questions from the question pool? I appreciate the help on
this.

Hi slewis6337
It is my understanding that each time you
display the Captivate output, you see a totally random
question. So if your question pool contains 50 questions, each time
your Captivate output presents the random question and draws from
the pool, it is truly drawing a totally random question.
I do believe that Captivate does keep track of which
questions have been used in the pool. To test this, try creating a
pool containing three questions. Then create four random question
slides that point at the pool. Then try running the Captivate. You
should see that as random question number four is encountered, the
screen goes totally gray. This is happening because you have
exhausted the question pool.
Sincerely... Rick

Why is the download link for the upgrade of Lightroom not working?

Am I the only one, for who the download link https://creative.adobe.com/de/products/de/download/lightroom?promoid=KSKAY ist not working? I just get the error site not found...

The 5.7 version. I found a different link, which was working, but I wasn't aware that's not just an upgrade but a completely new version you have to pay for again.
So I think I will stick to my version. But thanks for your answer anyway.

Does Labview have a Random Number Generator for U16 with a periodicity greater than 64 Million instances of U16words and one with SEED as the connector?

We are doing some testing that requires 64MegaWords be written to our DSP memory with random values to do a validity check and without repeating sequences with using the previous value as the seed for the next and us passing it the initial seed. The dice one doesn't meet that criteria, and I was not sure how the continuous random number generator parameters work and if any of them would meet this criteria. Anyone have any information that might help?
Thanks,
Sue

Hi suem,
There is no reason why you couldn't simply write a pseudo-random number generator by yourself. Simply select a random number algorithm you want to use and implement it in LabVIEW. You do not need to interface code written in another language in order to implement a pseudorandom number generator. If you have a DAQ card or something, you can also use inputr noise or some other hardware soruce to generate real random numbers. For that also LabVIEW is an excellent tool.

Outlook 2010 randomly asking for password

I know this is a frequent complaint, but I have not found a viable solution to stop this problem.
I am using Outlook 2010 on Windows 8.1 (with all the latest updates)
About a month ago, Outlook started to randomly ask for the username and password on two of my accounts.
I have tried all the solutions that I could find, but none work.
I have 3 accounts set up, 1 for me on a POP account with Verizon, a 2nd for my wife also with Verizon, and a 3rd is an IMAP for work.
I do not have a problem with the work account, but the 2 POP accounts randomly ask for the username/password and by the time I press OK will fail. Sometimes the scheduled send/receive works fine.
There were no credentials set up for these accounts (I have tried adding it and later removed it since it did not help)
I have tried removing the profile and readding as well as removing and adding the accounts again (using the same .pst files), losing my calendar in the process by the way.
If I manually initiate the send/receive, it usually works fine (I may have seen it ask for the PW once or twice)
The usernames and passwords are set up correctly and all the right boxes are checked.
I even set up groups so that the 3 accounts are scheduled at different intervals and the IMAP account only receives mail from the inbox without checking subscriptions and sends.
Any help would be appreciated,
Ken

Hi Ken,
Have you ever tried to clean the credential history cached in Windows Credential Manager? Sometimes incorrect credential cached in Credential Manager will result in this kind of issues:
Go to Control Panel, and then click Credential Manager.
Locate the set of credentials that has Outlook in the name.
Click the name to expand the set of credentials, and then click Remove from Vault.
For more steps to troubleshoot this kind of issue, you can refer to this ForumFAQ thread:
https://social.technet.microsoft.com/Forums/en-US/bcd2d9c2-1a1b-4446-bf32-69fee8cdf11b/why-does-outlook-keep-prompting-for-password?forum=outlook
Hope this helps.

Ideas on generating seeds for random number generators?

Does anyone here have any ideas or know of any good links to articles that discuss how to generate good seeds for random number generators?
I am aware that I could always probably call SecureRandom.generateSeed as one technique.
The major problem that I have with the above is that I have no idea how any given implementation of SecureRandom works, and whether or not it is any good. (For instance, Sun seems to hide their implementation outside of the normal JDK source tree; must be in one of their semi-proprietary sun packages...)
I thought about the problem a little, and I -think- that the implementation below ought to be OK. The javadocs describe the requirements that I am looking for as well as the implementation. The only issue that still bugs me is that maybe the hash function that I use is not 1-1, and so may not guarantee uniqueness, so I would especially like feedback on that.
Here's the code fragments:
     * A seed value generating function for Random should satisfy these goals:
     * <ol>
     * <li>be unique per each call of this method</li>
     * <li>be different each time the JVM is run</li>
     * <li>be uniformly spread around the range of all possible long values</li>
     * </ol>
     * This method <i>attempts</i> to satisfy all of these goals:
     * <ol>
     * <li>
     *          an internal serial id field is incremented upon each call, so each call is guaranteed a different value;
     *          this field determines the high order bits of the result
     * </li>
     * <li>
     *          each call uses the result of {@link System#nanoTime System.nanoTime}
     *          to determine the low order bits of the result,
     *          which should be different each time the JVM is run (assuming that the system time is different)
     * </li>
     * <li>a hash algorithm is applied to the above numbers before putting them into the high and low order parts of the result</li>
     * </ol>
     * <b>Warning:</b> the uniqueness goals cannot be guaranteed because the hash algorithm, while it is of high quality,
     * is not guaranteed to be a 1-1 function (i.e. 2 different input ints might get mapped to the same output int).
     public static long makeSeed() {
          long bitsHigh = ((long) HashUtil.enhance( ++serialNumber )) << 32;
          long bitsLow = HashUtil.hash( System.nanoTime() );
          return bitsHigh | bitsLow;
     }and, in a class called HashUtil:
     * Does various bit level manipulations of h which should thoroughly scramble its bits,
     * which enhances its hash effectiveness, before returning it.
     * This method is needed if h is initially a poor quality hash.
     * A prime example: {@link Integer#hashCode Integer.hashCode} simply returns the int value,
     * which is an extremely bad hash.
     public static final int enhance(int h) {
// +++ the code below was taken from java.util.HashMap.hash
// is this a published known algorithm? is there a better one? research...
          h += ~(h << 9);
          h ^= (h >>> 14);
          h += (h << 4);
          h ^= (h >>> 10);
          return h;
     /** Returns a high quality hash for the long arg l. */
     public static final int hash(long l) {
          return enhance(
               (int) (l ^ (l >>> 32))     // the algorithm on this line is the same as that used in Long.hashCode
     }

Correct me if I'm incorrect, but doesn't SecureRandom just access hardware sources entropy? Sources like /dev/random?What do you mean by hardware sources of entropy?
What you really want is some physical source of noise, like voltage fluctuations across a diode, or Johnson noise, or certain radioactive decay processes; see, for example
     http://www.robertnz.net/true_rng.html
     http://ietfreport.isoc.org/idref/draft-eastlake-randomness2/
     this 2nd paper is terrific; see for example this section: http://ietfreport.isoc.org/idref/draft-eastlake-randomness2/#page-9
But is /dev/random equivalent to the above? Of course, this totally depends on how it is implemented; the 2nd paper cited above gives some more discussion:
     http://ietfreport.isoc.org/idref/draft-eastlake-randomness2/#page-34
I am not sure if using inputs like keyboard, mouse, and disk events is quite as secure as, say, using Johnson noise; if my skimming of that paper is correct, he concludes that you need as many different partially random sources as possible, and even then "A hardware based random source is still preferable" (p. 13). But he appears to say that you can still do pretty good with these these sources if you take care and do things like deskew them. For instance, the common linix implementation of /dev/random at least takes those events and does some sophisticated math and hashing to try to further scramble the bits, which is what I am trying to simulate with my hashing in my makeSeed method.
I don't think Java can actually do any better than the time without using JNI. But I always like to be enlightened; is there a way for the JVM to generate some quality entropy?Well, the JVM probably cannot beat some "true" hardware device like diode noise, but maybe it can be as good as /dev/random: if /dev/random is relying on partially random events like keyboard, mouse, and disk events, maybe there are similar events inside the JVM that it could tap into.
Obviously, if you have a gui, you can with java tap into the same mouse and keyboard events as /dev/random does.
Garbage collection events would probably NOT be the best candidate, since they should be somewhat deterministic. (However, note that that paper cited above gives you techniques for taking even very low entropy sources and getting good randomness out of them; you just have to be very careful and know what you are doing.)
Maybe one source of partial randomness is the thread scheduler. Imagine that have one or more threads sleep, and when they wake up put that precise time of wakeup as an input into an entropy pool similar to the /dev/random pool. Each thread would then be put back to sleep after waking up, where its sleep time would also be a random number drawn from the pool. Here, you are hoping that the precise time of thread wakeup is equivalent in its randomness to keyboard, mouse, and disk events.
I wish that I had time to pursue this...

Yes. Many Creative Cloud plans include Acrobat Pro DC with Document Cloud services. Explore Creative Cloud plans.
However, if I follow the link to Creative Cloud plans, there is nothing to tell me whether Acrobat Proc DC is included in any of the plans. My plan is a yearly individual at $49.99/month.

Lightroom 5 defaulted to my Trial version. Can you please advise on what I did wrong? I can provide the serial number for the purchased subscription.

History - I had a 30 day trial version of Lightroom back in October. One small catalog of 1500 photos were contained in it. When I was prompted to upgrade, I incorrectly selected the option to "choose a different catalog" which prevented me from seeing my recent photos in Lightroom 5. It appears that my version of Lightroom may be a trial version instead of the version for my subscription purchase. Can you please help me with this? I will be glad to provide the serial number as necessary.

Without proper system info and other details nobody can tell you anything. for the time being, try another browser...

I have been using a Lightroom 5 including recent upgrades on my Mac Pro laptop for the past 1 year. This was purchased as an upgrade from Lightroom 4 for which I have a serial number. Today I purchased a new Macbook pro and loaded my Lightroom 5 however it is asking for my serial number which I have misplaced. I am unable to trace my serial number anywhere. I have even checked my adobe membership to locate my serial number but it does not seem to have any record which is strange as I have been using this software for over a year now and the previous versions since 2009. Could someone help me in my predicament.

ACR 8.7 has been released with support for the Nkon D750. Why no Lightroom support yet? Am I wrong or was support for the D810 available far more quickly?

ACR 8.7 has not yet been released. The ACR 8.7RC has been released. It is a Release Candidate - and as such, is not a final version. I wouldn't be concerned about a lack of Lightroom support until a final version is released.

How to install the add-on Photo Upload Dropbox for CC products, like Lightroom?

I have bought the add-on from Adobe to use it in Lightroom. My CC app says it is installed, but I can't find it in any of my CC apps (Lightroom, PhotoShop etc).

When you purchase an Add-on, the web page for the add-on has a tab that tells you where to find it and how to install it.
Go back to the page where you ordered it and look for the Where to Find It tab, shown below:
For further questions, it would be best to ask in the Lightroom forum.
