New version and distinct-values

Does the new version include improvements to speed up the distinct-values function?
As a review from ancient history (July), I need to look through thousands of small documents, each with one or more category tags, and generate a list of used categories. This took a very long time to do, and it was determined that the distinct-values function didn't used indexes. Further, we came to a lose conclusion that there was really no way to get decent speed out of this query with the current implementation.
At the time George also mentioned the possibility of future index manipulation methods that could avoid touching the documents at all, pulling the values out of the index itself.

Hi Chris,
The new release has an improved distinct-values() function, that uses an O(n log n) algorithm instead of an O(n^2) one. However, it still does not use indexes to optimise it's performance.
It may well be worth you checking it out. If you do, please let us know how it went for you.

  • My Mozzilla crashed: "We're Sorry....Firefox had a problem..." I download the new version and it is still giving me the crash report.

    My Mozzilla crashed: "We're Sorry....Firefox had a problem..." I download the new version and it is still giving me the crash report.
    I tried to loading in "safe mode" but I still could not open Firefox.
    I never received a crash i.d.

    It is possible that there is a problem with the files [http://kb.mozillazine.org/sessionstore.js sessionstore.js] and sessionstore.bak in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder]
    Delete [http://kb.mozillazine.org/sessionstore.js sessionstore.js] and sessionstore.bak in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder]
    * Help > Troubleshooting Information > Profile Directory: Open Containing Folder
    If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.
    Deleting sessionstore.js will cause App Tabs and Tab Groups to get lost, so you will have to create them again (make a note).

  • I have two versions of Pr, one is the latest 2014 and when trying to open a Pr2014 session, I get an error message saying the project was saved in a newer version and cannot be opened. Help

    I have two versions of Pr, one is the latest 2014 and when trying to open a Pr2014 session, I get an error message saying the project was saved in a newer version and cannot be opened. Could there be an issue with an older Pr application on the computer? Please help!

    You need to be very careful which project you open in which version.
    For 2014 make sure its on 2014.1 build 81.

  • How can I remove apps from my itunes library in version 11.0.0.163? The checkbox is no longer there in the new version and I do not see a drop down menu.

    In the new iTunes version 11.0.0.163 I tried to delete a free app but it still shows after I deleted it from all my Apple devices. The checkbox in the previous version of iTunes does not seem to be present in the new version and I do not see a drop down menu. And there are no Help menu choices either. I guess, I will otherwise wait for the new update to iTunes as of 12.10.2012.

    With iTunes 11 on PCs the drop-down menus are hidden by default - control-B should get the menus to show
    This screenshot is from a Mac, but it should be similar on a PC :

  • HT1711 I recently deleted iTunes off my computer by accident, when I reinstalled it I got the new version and I can't figure out how to get my music to store on my iTunes to transfer from my iPhone to iTunes.

    I recently deleted iTunes off my computer by accident, when I reinstalled it I got the new version and I can't figure out how to get my music to store on my iTunes to transfer from my iPhone to my iTunes.  I goal is to get my iPod filled with the music that I have stored on my iPhone and figured the only way to do so is to use iTunes as my transfer hub.  Any suggestions?

    Wow you're kind of a iTunes bully.  Dude the reason I am asking for advice and help is I am completely computer ********.  If I knew the answer I wouldn't be asking.  Anyways.  Question to anyone else. 
    If I have no music on my iTunes at all and no music on my computer, hard drive or any other version of storage yet there is a playlist on my iPhone. While my iPhone is plugged into my PC and my iTunes is up, is there a way to swap my playlist from my iPhone to my iTunes?  Directly?  Without downloading some new media source or backing up my old media source from my history.  The reason everything was deleted (iTunes and media source) was due to the size of everything and space it was requiring.  I am simply trying to get 233 songs from A to B. 
    I have tried magic but it is not working.

  • I just tried updating ITunes to the new version and it will not completely download and now I get an error message of MSVCR80

    I just tried updating ITunes to the new version and it will not completely download and now I get an error message of MSVCR80. Is there a problem with the new iTunes version?
    Now ITunes won't open.Help!!!

    Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features(Later)
    Remove all of these items in the following order:
    iTunes
    Apple Software Update
    Apple Mobile Device Support
    Bonjour
    Apple Application Support
    Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
    See also HT1925: Removing and Reinstalling iTunes for Windows XP or HT1923: Removing and reinstalling iTunes for Windows Vista, Windows 7, or Windows 8
    Should you get the error iTunes.exe - Entry Point Not Found after the above reinstall then copy QTMovieWin.dll from:
    C:\Program Files (x86)\Common Files\Apple\Apple Application Support
    and paste into:
    C:\Program Files (x86)\iTunes
    The above paths would be for a 64-bit machine. Hopefully the same fix with the " (x86)" omitted would work on 32-bit systems with the same error.

  • I would update to the new version of Firefox but I like my big Google Firefox start page. Don't think I'll have that with the new version and I don't want to give it up.

    I love my start page. It's nice and big with the Google search engine bar and Firefox earth symbol attached. I'm positive that the new version of Firefox will cause me to lose this particular start page so I refuse to do the update. If I download the new version and this happens I won't know how to get it back (tho' I did do it once and lost the start page so I went back into my Mac time machine and got the old version back. I was so relieved.) Thank you.

    If I recall correctly, you are talking about the default start page. To check if this is correct, type '''about:home''' in the awesome bar. If this is the same as your homepage, it will still be there when you update.

  • I just downloaded Firefox 5 and it said that my Yahoo toolbar will not work with it. Is this true? If so I will not use this new version and will switch to another browser if Firefox stops supporting the Yahoo toolbar. Thank you.

    I just downloaded Firefox 5 and it said that my Yahoo toolbar will not work with it. Is this true? If so I will not use this new version and will switch to another browser if Firefox stops supporting the Yahoo toolbar. Thank you.

    Add-ons contain a range of compatible Firefox versions, and Firefox honors the listed range by disabling the add-on if you are trying to run it on an unlisted version.
    I'm sure Yahoo! will update its toolbar eventually, but not every add-on maker supports beta versions of software.

  • Today I think firefox automatically installed a new version and after that it said my adobe flash was old so I had to update that. Now I can't open links in a new window.

    Firefox doesn't install new versions of plugins, but Flash may update itself automatically.<br />
    You are still one version behind on Flash, current is Flash 10.1 r85<br />
    If the Flash player didn't update properly then you need to download the full version and run the installer as Administrator (right-click: Run as ...)

  • After I installed the latest version of ITunes I get a message saying I'm missing the SQlite3.dll file. I have even unistalled the new version and then re-installed, still same message.

    After I installed the latest version of ITunes I get a message saying I'm missing the SQlite3.dll file. I have even unistalled the new version and then re-installed, still same message.

    With Windows Explorer, navigate to your C:\Program Files\Common Files\Apple\Apple Application Support folder.
    Copy the SQLite3.dll that you should find there, navigate to the nearby Mobile Device Support folder, and Paste it in there also.
    Restart the programme all should be well
    In case that your OS is (64 bit)
    1. Open windows explorer, go to location C:\Program Files (x86)\Common Files\Apple\Apple Application Support
    2. Copy file "SQLite3.dll"
    3. Now paste it in the folder  C:\Program Files (x86)\Common Files\Apple\Mobile Device Support
    4. Restart the programme, it should not display that message, it should be clear.
    Good Luck

  • I have an old version of the Logic in cds. Can I just download a new version and give the serial number so I don't have to pay twice?

    I have an old version of the Logic in cds. Can I just download a new version and give the serial number so I don't have to pay twice?

    No..
    You cannot download any version of Logic that you bought on CDs.... You must reinstall it using the disks that came with the boxed set.
    The only downloadable version now is Logic Pro X....which, like everyone else.... you must buy via the App Store... as it is a new version and there is no upgrade from any other version.

  • I am trying to open a previous completed project made on premiere pro CC 2014. i am getting a message that says the project was made on a newer version and cannot be opened on my new computer. However i made the older project on the same premiere pro CC 2
