What is happenig under the hood?

Hei,

at the University, I've been programming in C and Labview. So, I tried to understand Labview with C.

For example, if I call the function "get a Quebec" made the compiler really? From my point of view I would say that the compiler is to get low memory (allocate memory) for the buffer and create a few tips in order to pass data. Is this good?

Thanks for advantage.

A couple of points. First of all, its very human when learning something new to try to connect to something you already know - so you're about LabVIEW C well, it stop! trying to apply LabVIEW primitive languages like C, C++ or Java will always be mislead you. A perfect example is the problem with the queues.

You don't create queues in your LabVIEW code. All.You is ask a reference one. If it does not exist, LabVIEW creates and that gives you a reference to it. If the queue already exists, LabVIEW simply gives you a reference to the queue that is already there. Similarly, you don't destroy the queues. You say LabVIEW that you are finished with your reference to it. If LabVIEW sees that no one else uses the queue, it destroys it. If other places in the code are still using the queue, LabVIEW leaves the queue intact.

Second, unless you're pushing the limits in terms of speed and size data sets, not to sweat all that is really 'ongoing'.

  • Editing in Photos; What happens under the hood?

    Hello

    With the retirement of the opening, I was watching a replacement. The main contenders are Lightroom, Photos or a combination of both.

    In Lightroom, a detailed history of changes is kept, and I can go back one, several or all the stages of my change history. Each edition is non-destructive and I believe that stored in a file. I think what I see on the screen is always the result of a direct rendering of the raw data from the sensor more instructions recorded in the sidecar file.

    In the Photos, I wonder what's happening under the hood. There is no history of edits and I found no evidence of the sidecar files used. Can I return all the way the original raw file, but what I really wonder is I have change the file, change it again once, click done, change it again, click done, click done, run it through an extension, click done, what actually happens? Photos renders a JPEG image when I click on 'done' and open it for further processing when I change it again? Or can someone confirm there really data sidecar happening somewhere?

    Very cheesy, I understand that. But if I choose a photo app, so I want to use the best quality possible at any time. Using a JPEG file of the previous edition as the basis for the next, is not that. Building a list of instructions in a rendered file, is it.

    Anyone with this idea?

    Thank you

    In the Photos is also a kind of history of publishing, as in Aperture. You can cancel adjustments individually by unchecking the blue checkmarks in the adjustment Panel.

    You can also tell that the Photos is computer modifications of the original, because the original must be available, if you want to change.

    But it's different, if you use photo editing extensions.  In this case almost a new master will be created and successive modifications will use this master file almost, as previously in Aperture, when we used an external editor or a plug-in.

    After that I used an extension of editing, I see a large TIFF file in the resources folder in the photo library model, even if the original file is a JPEG of average size.

  • DW CS6 test server shows only the login screen of my site. Can't do under the hood live wiew. The pages I want to change/modify is visible only when I connect but I do not know how to reolve that.

    I'm trying to edit a CMS site to my needs and "open" pages is not serious, that is to say those that do not require the user to connect to. I can see and I can modify them according to my needs.

    The trickiest part is when I want to change/modify something inside. Then it wont let me. The only thing I see is the "Login" screen I can see the code and I can do what I need, but when I turn on 'Live wiew' is the log in page that greets me


    Tests of servers is correct because I can use it in my localhost

    Connection MySQL works as it should (Test OK)

    I guess that's something that has to do with permissions, but I don't know what.

    A CMS site, the page is usually filled with data that is stored in a database using a scripting language on the server side. Unfortunately, the Design mode only supports a static language like HTML, there is therefore no recovery information from the database.

    The only way out of your situation is to temporarily remove the permission to the user to the page that you are editing so that you do not to log-in each time. The problem is that you may forget to reactivate the authorization.

    What I always do is to open the site in a browser and verify the change in DW refreshing the page in the browser. In this way, you need to log-in once.

    For me, this happened from disabling, but do not uninstall McAfee site Advisor. Recommend site completely uninstalled and the problem disappeared completely. I had turned off before site Advisor, but it seems after a update to McAfee, he was back and then turn it off again caused this problem.

    Go to "uninstall a program" or "add/remove programs" in control panel. Find McAfee in your list (McAfee total protection for me). Click it and then click "Uninstall/Change" (right there in XP, up above in Vista or 7). I don't remember exactly what you see after that, but at one screen I was given the choice to uninstall the McAfee total protection and/or the Site Adviser. You can just check the Site Adviser and just uninstall the Site Adviser while retaining the rest of the McAfee protection.
    

    Good luck!

  • What happened to the option "reload"? (ITI used under the 'View' menu).

    When we look at some Web sites, you have a version of a page cached and force a reload to ensure what you are looking at the latest version. "recharge" used to be an option under the "View" tab, but it went from there in the last update. Where is he now?

    Firefox 4 by default the stop-button Go and recharge are combined and attached on the right edge of the address bar.

    When you type in the address bar, it will show the Go button. When loading a site is it shows the Stop button. Sometimes it shows the button reload.

    If you want separate buttons, right-click on a toolbar and select Customize, you can then drag the stop or reload buttons and place them elsewhere. If you place them in the order 'Reload-Stop' on the right side of the address bar they will be together again. For more information about customizing the toolbar, see https://support.mozilla.com/kb/How+to+customize+the+toolbar

  • Satellite L500D - what type of housing is under the battery?

    I found a place (I think it's the memory) under the battery in my satellite L500D. What type of housing is it? (It looks like a MicroSD card, but sign says: this is the crack of WIS - I searched but I did find what this means)

    It works in my laptop, or is it for other models?

    Hello

    Memory locations are placed near the Bay of dough.
    But the slots are not placed under the battery.
    It would be interesting to see the location on the image.

    As far as I know that the laptop does not support 3G so I n t think that there is a slot for a card 3G.

    Of course, the laptop supports a Bridge Media slot that handles the card SD, SDHC Card, Memory Stick, Memory Stick Pro, MultiMediaCard, but this machine in under is placed on the in front of the laptop.

  • Received a warning to unidentified on the network computer. Under the status of the network looked up and saw a computer I don't know anything. What is - this and how?

    Original title: computer not identified on the network

    Received a warning to unidentified on the network computer. Under the status of the network looked up and saw a computer I know nothing on my network. What is - this and what that can do. ?

    Implement the security of your network... How to do depends on details. If your network is at home on a wifi router, and then implement WPA2, which will prevent unauthorized as well as encryption of your data access.  Follow these steps on the router itself (once again the details depend on your situation.)

    While I'd love to implement WPA2, WPA2 will not accept my network and I am limited to WPA.  My point is that if it is a wireless intrusion (we don't even know if it's wireless at this point), then the security settings on the router must first be discussed with the manufacturer ISP or router so that they are appropriate for devices and services and programs.

    It could also be a USB transmitter attached to the computer.  It might be the malicious program or a problem with the firewall or a real hack of the computer through the firewall or caused by malicious software (even if you use cables or wireless).  It could be the entire network (but the number of computers which implies) or only this one computer.  It could also be a system service using the network and not really another computer in itself (in office what he says and where - some may be difficult to recognize and interpreted as another computer).  There are many possibilities.  We do not know what the warning generation program or what he says.  More information is needed.  I would also like to work on it - and it can follow to her new home.

  • What is the slot under the battery

    Just got my new T400 yesterday and was very excited about it.

    have a question here.  I noticed a place where the mental battery seven pines touch laptop, in virtue of this place, there is a small plastic film with a similar size to a micro-sd card card. He's also a figure resembles a card SD (rectangle with a corner cut). If I pull the plastic film, the card can also be removed, but the film remains in.

    I don't find it anywhere in the manual. What is this site supposed to do? I guess that is not the SD card reader, because it's on the left side of the laptop, not hide under the battery does.

    Thank you.

    I think that it is the location for SIM card for the machine with system WWAN. If you do not have the WWAN, it's just a dummy slot that does nothing.

    I get a message indicating that Windows cannot open blah blah blah and to communicate with MSN and their awareness of the 56 under the butterfly.  My problem is HOW in the WORLD contact you MS?   I tried and has been achieved here.

    I searched the internet for an explanation for what is the problem and a SOLUTION.  Of course, all I get are 'quick fix' downloads for $39.99 - which, in my moment of desperation, I fell prey to., of course, he did not - it really did a restore of the system - which, moreover, was the FIRST thing I did.

    Someone at - it neither suggests - HOW to solve the problem - or how to get help from MSN?

    What is the Panel to learn under the Windows Menu and why is mine dimmed in Adobe Illustrator?

    [Ask the right help forum... Left non-technical Forum Lounge for forum specific program... MOD]

    It is still at the experimental stage, as far as I know. It contained tutorial, so it provides a file HAVE, as appropriate, and step by step instructions. I wouldn't assume that it contained for the functions of learning.

    You will need to

    -be in the English language setting

    -have your status as a beginner (which could have other consequences on the content of the emails you get from marketing people)

    But still could not have because of the experimental status of it.

    If you want instructions step by step as the Panel offer you could get there faster with this: CC Illustrator tutorials | Learn how to use Illustrator CC

    I guess (I have not the Panel either) that are identical or at least very similar tutorials and instructions.
