What does this start screen?

13 "MacBook Air, purchased in November 2015.

No previous question. Computer has been turned off, I've been carefully (or not) wipe the keyboard accidentally pressed the power button and goodness knows what that other keys. Computer does its usual power sound, then THIS screen came. I don't know what to do with it.

Really, I would like to return to my usual startup/login screen. Can I just turn off again?

I'm stupid on the functioning of computers... this form scares me. Help!

Thank you.

(I've updated El Capitan, but I don't know if I have the latest update).

It's just the Manager start screen. If you hold down the Option key (⌥) at startup you get this screen where you can choose which drive start. You only have one option specified.

It is enough to select Macintosh HD and continue and it will start normally.

  • What does IMAQ start?

    Hi all

    What does IMAQ start? On my eval of camera position, it fails in certain circumstances, and I am trying to isolate the cause.

    Reminder: There is a rating system provided to me by MAY. When I use it as they delivered, it works fine. But of course, I need to perform very differently than the design of the MAY, and that's where the trouble starts.

    The system is a Lenovo ThinkCentre running Windows 7 Pro SP 1 64-bit.

    NOR-1433 PCIe framegrabber, two Camera Link cables running to the eval Board.

    LabVIEW 2010 32-bit version,

    NOR-MAX version 5.5.0f0,

    NOR-IMAQ version 4.7.3,

    Camera files 3.0.1 generator

    The eval system was originally designed as a step 4, CL Medium. To illustrate a concept we develop, I want to run 8-tap CL full (really, I want 10 bits 8 tap but that's another debate). I used CFG to change the original file of the ICD and saved as a new file. When I use NEITHER-Max to move to this new camera file, the program fails when IMAQ Start is called, error -1074397153 is returned. «NOR-IMAQ: impossible to detect a recognizable video source'.»»  I'll join the two files from the CIM.

    I see two possible culprits:

    (1) IMAQ start is reading of registers on the camera and find something inconsistent with the settings in the file of CIM

    (2) items in the bad file CIM contradict

    Hi, tonytiger34.

  • What does this query? Am I wrong?

    Select AVG (NTC)

    Select DriverID, cast (COUNT (9) as float) cnt

    of myTEST2 one

    where exists (select 1 from myTEST2

    where DriverID = a.DriverID

    and layout = "guilty".

    )

    DriverID group

    ) x

    I think that his calculation of the average number of people with the provision of a culprit.

    Hello

    If a subquery in a WHERE clause clause refers to a value of the Super-requete, then the subquery is called a correlated subquery, and it runs a separate period for each line of the great query of.  This is the query you posted, reformatted to make it more understandable:

    Select AVG (NTC)

    de)

    Select DriverID

    , NTC cast (COUNT (9) as float)

    of myTEST2 - Alias defined here

    where is (-beginning of correlated subquery)

    Select 1

    of myTEST2

    where DriverID = a.DriverID - Alias a used here

    and layout = "guilty".

    ) - End of subquery to correlated

    DriverID group

    ) x

    ;

    The average subquery (i.e. the query with the GROUP BY clause) has a WHERE clause, so every time a line is located in the table mytest2, that where clause gets evaluated and the results of this condtion say whether the line should be included or not.  Oracle has found a line with driverid = 1 in the table mytest2 and then decides if it will use this line.  What does exactly to decide?  He runs the EXISTS subquery and sees if the subquery produces all lines or not.  When it ends with the line that is driverid = 1, there may be a lines with driverid = 2, rerun the query EXISTS Tahina, see if the subquery produces all lines and use it to decide if the line is stored.  The computer could pick the other row with driverid = 2 and repeat the process.

    Using a table alias told Oracle that the subquery EXISTS is a correlated subquery and it also says there that the values of the Super-requete to use.  Therefore, in the scenario I described earlier, when the Super-requete is to decide whether to keep the line with driverid = 1, it executes the equivalent of this EXISTS subquery:

    Select 1

    of myTEST2

    where DriverID = 1 - because a.DriverID = 1

    and layout = "guilty".

    Then, when he is to decide whether to include one of the lines with driverid = 2, it executes the equivalent of

    Select 1

    of myTEST2

    where DriverID = 2 - because a.DriverID = 2

    and layout = "guilty".

    There is nothing magical about the alias one.  This is an identifier arbitrariness that is defined in the Super-requete of and can be used in the subquery.  You need some type of alias in this case because the EXISTS subquery can be based on the exact same table that its users of subquery, which is mytest2.  Using your 2 copies of the same table, similar to the way you have 2 copies of the same book, open on different pages.  If you do not have an alias, no column name could make reference to the copy of mytest2 in the subquery EXISTS, or to the copy used in the Super request and by default is that it means the copy in the subquery.
