Newbie on the aperture lens question sets

I did have the chance to try a goal at opening fixed yet. I just wanted to know if you can still change the opening of like for example f/2.8 to f/8 or more. ? Or is the only opening you can f/2.8. How does this work?

This is not a "fixed" aperture because it cannot be changed.  This means that this isn't a "variable" opening that changes as the focal length changes.  This lens keeps f2.8 it is thanks to its focal range.  It can and it has all the apertures from f2.8 to f22.

This goal is, BTW, the best 24-70mm made today.  There's nothing better.

  • Newbie on the vector art questions

    I am importing some vector clipart. I need to convert to grayscale before I can use it.

    QUESTION #1: Can I convert it to grayscale in InDesign, or should I open art in Illustrator and convert grayscale it?

    QUESTION #2: Since this is the vector art, can I simply intensify it as top that I do, or do I need to say ID or Illustrator what size I want?

    Thank you.

    1. you must do this in Illustrator.

  • Newbie with the mouse event question

    Hello! I started playing with as3, and I have a function for mouse clicks that draws a shape on each click. However, the mouse click event does not appear to work except when I click on a MovieClip, that I placed in the middle of the screen. Is there a way to make the mouse click event recognize when I click anywhere on the screen?

    I read that the Oracle background processes are dbw0, lgw0, trunc, smon, pmon, cjq0 and arc0. However, I noticed that these processes are not in the list of processes. I'm in Oracle Database 11g in Oracle Enterprise Linux. I see that there is an Oracle process well. Background processes are included within the Oracle process for a given case?

    Windows Setup does not load in safe mode, that's why you get the error probably. Why are you installing in safe mode? Why not normal mode?

  • "the apprentice" crypto transform-set issues

    Greetings - I was sort of a backup person or I guess as "Apprentice" to our network administrator who has recently retired. Same story, guess who is responsible now to figure it all out.
    We have a pair of 5510 in the main office, the second is a "fail-over" the death of number 1.
    Our remote offices have 5505 s (system image file is disk0: / asa844-1 - k8.bin) which connect here on LAN-to-LAN via the Internet connection provided to this office by various Internet service providers. Mostly good, some "tunnels" or connections remain for days, or even weeks or sometimes months without any problem.
    But we have some offices of disorder where each connection fall fairly regularly or in one case, they often lose the ability to connect to the connector of the computer central address here. We have different subnets in our offices, the mainframe and email are provided by the State, or IT Enterprise/ITE Central. Some of our 'networks' uses public addresses, some private.
    Each remote office has its own network. The numbering is based on number of office accountant, not that it's really important.
    Thus each remote office will have a private 10.252.xxx.xxx plan where the first xxx film series is the office number and the last series of xxx is the range assign us, normally broke up with a 27 (255.255.255.224) mask.
    This established, a typical office will be 10.252.24.1 - 30 (10.252.24.0 network)
    I was thrown in the fire and said to our offices in problem to understand. In trying to figure out why things are what they are, I find things which surprise me. Can't put my finger on it, but it just doesn't feel good.
    A topic at a time - I find Cisco documentation that says you can assign a MAXIMUM of 6 transform sets to all that.
    HOWEVER, I find more than 6 in the list, 11 actually. I can't understand why so many and what the heck we even need more than 1 or 2 for anyway. I think it's here because updates to the os on the means of years that things seemed simply by the process of update and I think also that some has been everything simply because things have been tried - to throw in and see if it helps. I hate this.
    I want these cleaned and only the code that is required to be left - and in a way I can understand. And if that helps with our connection issues, great, but if not at least things will be easier to sort through and understand.
    This is the area in question for the purposes of this post-
    Looking at the small part of our config in a typical remote office ASA5505 I'll post below - which belongs or is necessary, and what is foreign and may or must be destroyed or deleted.
    Why 11 lines of transform-set?
    Spoke 6 max? (this quote) > after a set of transformation configuration, you assign it to a card encryption. You can assign up to six sets of the transform to a card encryption.

    I have already corrected some problems by turning the NAT - T on offices provided Internet via a DSL modem, that the modem is apparently a NAT - external interfaces on the 5505 device s with DSL have 192.168 addresses and the MODEM has the Internet address where the provided cable modem sites have a direct public address on the external interface.  Something bothered me on these sites - and I was able to understand what and why. This example configuration above mind right now - but I don't know why.

    Just an another public employee trying to make it work properly, having to learn the hard way now...
    I apologize if this isn't the correct area to post.
    Thank you.

    You are welcome.

    Regarding your questions Suites A and B - two Yes.

    DO first - make a backup of your configuration. It is a good idea during changes of any kind. If you have doubts, backs up front and backup after. Do a comparison aside to check your work. (I use ExamDiff make comparison of less prone to human error long text files.)

    When you have preshared keys (which appear as hashes when you perform a simple "show run"), you must use the following (when recording the output of your senior year):

    term pager 0more system:running-config

    The first line will make all output scroll by at the time and the second will print configuration with pre-shared plaintext keys.

  • We can add a button to the BP to approve Budget so that it can read all the charges in question cost journal line and auto fill on the grid.

    Hi all

    We can add a button to the BP to approve Budget so that it can read all the charges in question cost journal line and auto fill on the grid.

    Let's say I have a cost with 5 code cost journal

    Code 1 price

    2 cost code

    Code 3 cost

    Code 4 cost

    Code 5 cost

    BP budget approval, after that I click on New, can I add a button to the tab the line items so that when I click on this button, it reads all codes of cost in the cost journal and auto fill on the grid?

    You can create a new 'model' BP for this purpose. Line item type. Then add a line manually with a cost on each code. Then you can use the copy in your BP BA record consolidate the function to copy the line items to the new folder of BP (including all cost codes) into your folder of BA. That is to set up a model record once with all cost codes and then copy consolidate billing it to all lines new record of BA. would this work?

    When the screen is at least 1220px everywhere, the page is perfectly centered. The smaller screens don't display the page in the same way because, as you said quite rightly, the container has been set to 1200px - the extra 20px is used for the scroll bar.

    This means that the page is far from being reactive.

  • Timer remains on all the slides in question (Captivate 5)

    I created a quiz with 20 questions and you want to limit users have 10 minutes to complete.

    The build in widget shows only a slide...

    Anyone know how to create a timer that maintains the counting and will stay on each question slides?

    Thanks for the help of kindness!

    Hello

    If you want to display the timer and restart on each slide, add it to the slide master. If you want the calendar for the full amount of slides, add it to the first Question slide and set it to show to the rest of the project. If you must get rid of the timer later (after the slides in question), you'll have to hide using an action at the entrance to the first slide where you won't see the widget of the timer.
