What are hiutil and mdworker? - they're maxing out the CPU!!

So I upgraded this afternoon to Lion on my 13" macbook air from the App Store; first of all the reboot crashed, then a hard off and back on sorted that out.
Now hiutil (and sometimes mdworker) are trashing the CPU constantly at 90-100% (and making the fan go crazy with it)
Anyone have any idea what these threads are?
My MBA is now unusable because of these!!
Cheers, Simmo

mdworker is the Spotlight indexer. Spotlight is a bit wonky in Lion (as it was in SL 10.6.0)…be patient; it might not be fixed until 10.7.2 or so. If you don't use Spotlight, consider turning it off in SysPrefs. It'll cut that process.
hiutil seems to be a low-level process for Help pages. It's probably indexing those (to get the snappy search results from the Help menu).

  • 0.41GB of my iPod Touh 4G' is taken up by something called 'Others'. What are 'Others' and can they be deleted or are they an essential part of the iPod and embedded in it? If not essential how do I go about deleting it to enable me to add other pictures

    0.41GB of my iPod Touch 4G's capacity is taken up by something callked 'Others'. What are 'Others' and will it be o.k to delete them? If so how do I go about doing it as there is no trace of a file on either iTunes or my iPod?

    Other content is typically miscellaneous data used by applications you have installed - could be save data (e.g. for games), or documents you've created. There's no easy way to determine precisely what it is, but the only way to clear it is to either delete it from within the respective application, or remove the associated application altogether - neither of which are typically practical.

Then some bright spark at work told me I need the Gear drivers so  I downloaded the software and installed again.
    Sorry, just this minute went to insert image  and it is giving me a message saying this sort of content  is not allowed?.

  • What can I do about WSdaemon maxing out the cpu?

    Activity monitor shows WSdaemon using unto 120% cpu usage, my fan is running almost constantly. This used to happen while watching films but now whenever I surf the net.
    Anyone got a solution?

    See here: https://community.webroot.com/t5/Webroot-SecureAnywhere-Complete/Is-Webroot-Secu re-Compatible-with-OSX-Mavericks/td-p/64245

  • What are ROWID and ROWNUM? Are they stored in database and where?

    Hi All,
    can anybody please answer this question
    What are ROWID and ROWNUM? Are they stored in database and where?
    Thanks,
    Srini

    ROWID can be thought of as a pointer to the physical location (on disk) of the (table) row.
    From a ROWID value, Oracle can extract the file, block-within-that-file and offset-of-the-row-within-that-block. Using these, Oracle can directly access a disk block to retrieve a row.
    ROWNUM is a just sequence number of a row within a result set of a query.
    As said by other repliers, both are not stored. They are 'constructed' when you reference them inside a query.

  • What are high and low values in sharepoint 2013 user permissions?

    So I hit this api:
    http://win-a3q7ml82p8f/sharepoint_site/_api/web/roledefinitions/
    And got the different high and low values. But I am not clear with what they mean:
    For eg:
    High: 176, Low: 138612833
    and
    High: 176, Low: 138612801
    So for different values of Low how does it change the permissions?
    For 176 its binary is 10110000. So looking at this table here: http://www.dctmcontent.com/sharepoint/Articles/Permissions%20and%20Mask%20Values.aspx
    I can understand that 176 would mean the following set of permissions:
    DeleteVersions
    OpenItems
    ApproveItems
    But what's confusing me is, that user has OpenItems permissions but not ViewListItems permission? Am I wrong in understanding this?
    Also how does the value of Low change the overall user permissions?
    Note: I looked at this answer: http://social.msdn.microsoft.com/Forums/sharepoint/en-US/9d6df168-e8f5-4323-8c34-0646c03eff68/rest-api-what-are-high-and-low-in-effectivebasepermissions-and-getusereffectivepermissions?forum=sharepointdevelopment

  • What are valid and invalid email address characters

    What are valid and invalid email address characters in Exchange 2010, for example can you have Conan.O'[email protected] is there a document that shows the valid and invalid sysmbols?

    Hi
        The format of email addresses is
    local-part@domain where the local-part may be up to 64 characters long and the
    domain name may have a
    maximum of 253 characters - but the maximum 256 characters length of a forward or reverse path restricts the entire email address to be no more than 254 characters.<sup id="cite_ref-0">[1]</sup>
    The formal definitions are in RFC 5322 (sections 3.2.3
    and 3.4.1) and RFC 5321 - with a more readable form given in
    the informational RFC 3696<sup id="cite_ref-1">[2]</sup>
    and the associated errata.
    Local part
    The local-part of the email address may use any of these
    ASCII characters
    RFC 5322 Section
    3.2.3:
    Uppercase and lowercase English letters (a–z, A–Z) (ASCII: 65-90, 97-122)
    Digits
    0 to
    9 (ASCII: 48-57)
    Characters
    !#$%&'*+-/=?^_`{|}~ (ASCII: 33, 35-39, 42, 43, 45, 47, 61, 63, 94-96, 123-126)
    Character
    . (dot, period, full stop) (ASCII: 46) provided that it is not the first or last character, and
    provided also that it does not appear two or more times consecutively (e.g. [email protected] is not allowed.).
    Special characters are allowed with restrictions. They are:
    o   
    Space and
    "(),:;<>@[\] (ASCII: 32, 34, 40, 41, 44, 58, 59, 60, 62, 64, 91-93)
    The restrictions for special characters are that they must only be used when contained between quotation marks, and that 3 of them (The
    space, backslash \ and
    quotation mark " (ASCII: 32, 92, 34)) must also be preceded by a backslash
    \ (e.g.
    A quoted string may exist as a dot separated entity within the local-part, or it may exist when the outermost quotes are the outermost characters of the local-part
    (e.g. abc."defghi"[email protected] or
    "abcdefghixyz"@example.com are allowed. Conversely,
    abc"defghi"[email protected] is not; neither is
    abc\"def\"[email protected]). Quoted strings and characters however, are not commonly used.
    RFC 5321 also
    warns that "a host that expects to receive mail SHOULD avoid defining mailboxes where the Local-part requires (or uses) the Quoted-string form".
    The local-part "postmaster" is treated specially - it is case-insensitive, and should be forwarded to the server's administrator. Technically all other local-parts
    are case sensitive, therefore [email protected] and [email protected] specify different mailboxes. However most organizations treat uppercase and lowercase letters as equivalent, and also do not allow use of the technically valid characters
    (space, ? and ^). Organizations are free to restrict the forms of their own email addresses as desired, e.g.,
    Windows Live Hotmail,
    for example, only allows creation of email addresses using alphanumerics, dot (.), underscore (_)
    and hyphen (-).<sup id="cite_ref-2">[3]</sup>
    Systems that send mail must be capable of handling outgoing mail for all valid addresses. Contrary to the relevant standards, some defective systems treat certain
    legitimate addresses as invalid and fail to handle mail to these addresses. Hotmail, for example, refuses to send mail to any address containing any of the following standards-permissible characters:
    !#$%*/?^`{|}~
    Domain part
    The domain name part of an email address has to conform to strict guidelines: it must match the requirements for a
    hostname,
    consisting of letters, digits, hyphens and dots. In addition, the domain part may be an
    IP address
    literal, surrounded by square braces, such as jsmith@[192.168.2.1], although this is rarely seen except
    in email spam.
    Examples
    Valid email addresses
    <tt>[email protected]</tt>
    <tt>[email protected]</tt>
    <tt>[email protected]</tt>
    <tt>much."more\ unusual"@example.com</tt>
    <tt>very.unusual."@"[email protected]</tt>
    <tt>very."(),:;<>[]".VERY."very@\\\ \"very"[email protected]</tt>
    Invalid email addresses
    <tt>Abc.example.com</tt> (an @ character must separate the local and domain parts)
    <tt>[email protected]</tt> (character dot(.) is last in local part)
    <tt>[email protected]</tt> (character dot(.) is double)
    <tt>A@b@[email protected]</tt> (only one @ is allowed outside quotation marks)
    <tt>a"b(c)d,e:f;g<h>i[j\k][email protected]</tt> (none of the special characters in this local part
    is allowed outside quotation marks)
    <tt>just"not"[email protected]</tt> (quoted strings must be dot separated, or the only element making
    up the local-part)
    <tt>this is"not\[email protected]</tt> (spaces, quotes, and backslashes may only exist when within
    quoted strings and preceded by a slash)
    <tt>this\ still\"not\\[email protected]</tt> (even if escaped (preceded by a backslash), spaces, quotes,
    and backslashes must still be contained by quotes)

  • What are advantage and disadvantage for Physical Standy and Logical Standby

    HI,
    What are advantage and disadvantage for Physical Standy and Logical Standby configuration?
    Thanks
    Ken

    Logical standby database
    The key advantage for logical standby databases is that they're opened read/write, even while they're in
    applied mode. That is, they can be used to generate reports and the like. It is indeed a fully functional
    database. Also, additional indexes, materialized views and so on can be created.
    However (this being a disadvantage) not all datatypes are supported.
    Oracle (or more exactly the log apply services) uses the primary database's redo log, transforms them into
    SQL statements and replays them on the logical standby database.
    Physical standby database
    A physical standby database is a byte for byte exact copy of the primary database. This also means that
    rowids stay the same in a physical standby database environment.
    Oracle (or more exactly the log apply services) uses the primary database's redo log to recover the
    physical database.
    A physical standby database might be opened read only; however, the received logs are in this case not
    applied. When the logs are applied, the database is not accessible (it is then in a managed recovery state).

  • What are Validation and simulator

    can any one explain what are Validation and Simulators are ???
    what is there importance and how they work in SAP ??
    Regards,
    Milindkumar

    Are you referring to validation rules and simulations? Whereby validations allow the checking of values and combinations of data as they are being entered in SAP. Because the data is validated before it is posted, only correct information enters the system. For example if you have a cost center X that should not post to account Y. You create a validation that checks to see if cost center X is entered whether the account is Y. If the account is Y the validation will stop the entry from being made.
    Simulations normally are when data is checked for accuracy or verfied before posting. Simulations usually allow the verification of data by displaying that entries that will post or will be created only after the post button or process occurs.

  • What are strengths and weaknesses of the sap.m.Shell and sap.m.App as container for an application wrapper?

    My question today: What are strengths and weaknesses of the
    sap.m.Shell
    and
    sap.m.App
    as container for an application wrapper?
    I currently use non of them, but I see the advantages.
    SAP best practise is to use one of them or nest them as shell > app. What are strengths and weaknesses of the approaches?

    We prefer to say, the tender mercies of the Fetch block.
    You'll notice the "wfm info" cluster as an output of the Fetch
    VI.  This cluster has gain and offset members- use these to scale
    your binary data to floating point voltage representation.
    As you point out, the numbers won't be exactly what you expect given
    the vertical range and the device resolution.  There are a few
    reasons for this.  First, we don't use the absolute full scale of
    the ADC for the maximum input voltage.  There are a couple of
    codes of headroom at the top and bottom.  This allows your input
    signal to slightly exceed the specified vertical range without clipping
    (you'll get a warning from the driver).  Second, these gain and
    offset numbers take into account calibration information for your
    device.  Using these numbers will correct for small deviations
    from the ideal offset and gain.
    So if you use the gain and offset numbers from the driver, your
    measurements will be more accurate than if you assume 0 offset and
    perfect gain.  They will be most accurate if you make sure to
    perform a self-calibration once the device is in your system and at the
    temperature that your tests will be run.

    I have random excel files on my desktop that cannot be deleted. What are these and how can I trash them?

    They appear as mounted DMG files.If you right click on them mdo they have an Eject entry?
    Have you set the OS to Show All Files with a terminal command? If so take that off for now.
    Look in your Home folder (Users/UserName) and then the Desktop subfolder under it. Do you see all these files/folders/drives?

    Hi Jagrut,
    If you are talking of support token then,
    TOKENs are nothing but the issues faced in the actual live system(Production).
    So the end user who is facing will raise it, it will be assigned to the production support team and they will solve it.
