Impact of anonymous

Hello

I have two examples to explain my question:

1)

New Thread() {}
public void run() {}

do some process

}

}. start();

2)

Wire processThread = new Thread() {}
public void run() {}

do some process

}

};

processThread.start ();

Which option is right in the perspective of garbage collection? or are the same?

Someone tell me that we should not have option 1) which is the creation of anonymous, he says to have option 2). is it so? Is THAT JVM verifies references of son for garbage collection?

I want to know what are the benefits that option 2) which I'd rather not.

Help, please.

The JVM verifies references of thread for garbage collection. Normally, as Simon pointed out, a thread is subject GC upon return from the run method. (When a thread is started, the system keeps a reference to it until its run method returns, it will not GC'ed before that, even if you continue to reference in your code.) However, with option 2, the reference in your code prevents the GC thread'ed (even after it ended) as long as the reference is under tension (has not been reassigned or went out of scope).

As arkadyz says, the only reason to avoid option 1 is if you need to interact with the object thread itself after that it started. In fact, there is a second reason: arbitrary code style standards.

Edit: actually, both options 1 and 2 are examples of anonymous inner classes. Arkadyz option only 3 is not anonymous.

  • Order is created for the anonymous user without persistence of profile

    Hi all

    Could you please specify o how to implement below scenario

    Order is created for the anonymous user without persistence of the profile using cookies. So that when the user visits the site next time we can load

    order/cart previous from browser cookies.

    Yes, you can do that, the orders can be persisted without persistence of profile, but persistence of anonymous orders will increase the number of orders in the table quickly and can have an impact on performance, so if you plan to do it this way then make sure that your AbandonOrderScheduler job is running to clean up orders.

  • Anonymous performer of Oracle PL/SQL in the Production environment leave a residue?

    Hello

    In my project, we have a large PL/SQL in Prod-Replica Envt to generate scripts. However, to reproduce Prod for this Prod-Replica lasts long and is causing a delay to respond to change requests.

    We have READ ONLY access to Prod DB, but we cannot deploy the PL/SQL Package it. We plan to convert the PLSQL in an anonymous block PLSQL and running it in PROD DB to get real data. Alternatively, we can run it directly or via Java and then read the DBMS output later. as mentioned here-> the use of cursors and results in Oracle PL/SQL, Java/JDBC - Stack Overflow

    , However, is not an expert in PL/SQL, I wanted to know, if it leaves residues in PROD outside the additional load a temporary server for read queries. We only select queries in this PL/SQL and so I donot believe we leave triggers or change the DB somehow.

    Can you please let me know the possible consequences of it.

    -Thanks & Regads

    -Scott

    There will be an impact on the server, the conversion of code unit of PL/SQL (procedures and functions) must be encapsulated in a single code PL/SQL anonymous block.

    This anonymous PL/SQL code block needs to be parsed and compiled - burn a lot of CPU (that oppose the use of unit code already compiled PL/SQL).

    This anonymous PL/SQL block is likely to be very large because it contains too many units of PL/SQL source code. This needs memory to the server as the whole code block will be stored in the shared pool (for analysis).

    Another impact on performance would be wise to network. It requires more bandwidth to transfer this big block of code (created by the customer) to the Oracle server. This increases latency. And is not an evolutionary approach.

    So no, there is no "residue" of the code inside the actual physical database code is never stored in the database. However, this approach and the code will affect negatively network and server resources.

    You should consider the problem and determine if this solution you have in mind, justifies this impact.

  • get anonymous on the Internet - how?

    How can I be incognito when you surf the Internet, which is not allowing the sites I visit to know me.

    It is difficult to be completely anonymous, there are many technical sites can recognize you. In Incognito or private browsing mode, Firefox does not distribute the cookies that have been set in regular browsing windows. However, sites can still learn your IP address, plugins and optionally data stored by Flash Player.

    To hide your IP, you might consider a private VPN or TOR service.

    To manage what plugins are listed then to ask Web sites, you can change an internal preference (plugins.enumerable_names - he is not very good documentation on this subject at the moment, but this article has more information: http://www.ghacks.net/2014/07/11/hide-plugins-visited-links-webrtc-we...).

    To control the access and the use of Flash local storage, you can try an add-on like BetterPrivacy.

    Of course, block sites of information normally find available can break some of them...

  • UserAgents - impact technically in Fx browser (and using with fluid App)

    Hello:

    I don't know what the impact of a "user agent". I don't know if I chose the iPhone user agent on my Macbook, it means I can do things that Web site owners/developers have tried to limit to the iPhone for example read the full version of magazines for free. So I guess that a user agent tells the owner/designer of website 'our device' somehow we are somehow.

    But a user agent does nothing else on the technical plan for the browser?
    for example

    > no User-Agent controls whether a user script requiring xx can use xx (where xx = https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js). I can run this successfully using GreaseMonkey userscript in Fx, but it fails to run approx. fluid userscripts a in-app, no plug-in is required.

    > no User-Agent controls how low I can zoom in. Current zoom level is limited to 50% with the user agent below. More useless.

    I wonder what I started to play with the app purchased, fluid.
    Fluid converts a SSB (Single Site Browser) - aka a lot of apps that are now pure web browser but really an app), in a quasi-app, so it can sit on your dock, use OSX notifications, use split window panels / trays etc...) Liquid is no where near as powerful as Fx, but there is no integration with the OSX notifications which at the moment I can't find an add-on that allows this via the webkit. Several modules now use notifications for OSX, so I know it must be possible (for example to download helper).

    The latest version of the fluid is 1.8.3 I bought recently. By default, I opened user agent and I see this:

    Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_3) AppleWebKit/0600.5.17 (KHTML, like Gecko) Version/1955 FluidApp Safari/0600.5.17

    No idea what this user-agent is really telling me. I'm on OSX 10.10.3, yosemite I use the last FX (38 recently updated this week) and I don't use Safari.

    Thanks for your help.

    I can't answer on the liquid, but Firefox itself can not be fooled by what you specify as your user agent. For example, it asks what OS it is running on the operating system, and he knows that it's Firefox.

    I think that most of the userscripts are designed with limited space in mind, such as Greasemonkey and Scriptish on Firefox (and maybe Waterfox and Pale Moon), Tampermonkey on Chrome and maybe one or two other maximally. Specific points in the user agent string probably does not matter.

    > no User-Agent controls how low I can zoom in. Current zoom level is limited to 50% with the user agent below. More useless.

    Again, I think not. But you might have success change this setting in Firefox:

    (1) in a new tab, type or paste Subject: config in the address bar and press enter/return. Click on the button promising to be careful.

    (2) in the search above the list box, type or paste the zoom and make a pause so that the list is filtered

    (3) double-click the preference zoom.minPercent and try to enter a lower minimum (for example, 25 for 25%).

    The latest version of the fluid is 1.8.3 I bought recently. By default, I opened user agent and I see this:

    Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_3) AppleWebKit/0600.5.17 (KHTML, like Gecko) Version/1955 FluidApp Safari/0600.5.17


    No idea what this user-agent is really telling me. I'm on OSX 10.10.3, yosemite I use the last FX (38 recently updated this week) and I don't use Safari.

    My guess is that liquid wants website who do not recognize FluidApp treat it like Safari or any other browser Webkit (Safari and Chrome are popular browsers based on Webkit).

  • Re: Satellite L650 / 07C - HDD (Hard Drive Impact Sensor) shock protection system

    I just bought a Satellite L650 / 07C. When I bought it from the dealer, I was under the impression that this model came with the function disk hard drive shock protection system (hard drive Impact sensor).
    I ran the Toshiba PC Health Monitor application, but it seems not to have this function - it gives me the power settings, Temp and fan are monitored, as well as a status of hard disk drive, but nothing on the disk hard drive shock anti-siphoning (hard drive Impact sensor).

    Under my file utilities Toshiba HDD SSD Alert application that shows the same icon as the one I saw in the reseller on their Toshiba Satellite when they did there evidence the shock protection system. I ran this application, but it gives me just a status message that the drive works properly.

    Could someone please confirm with certainty whether the model I have this feature.

    Thank you very much.

    Everything goes well with your laptop. I made a screenshot and uploaded to show you:

  • Software for the NI 9233 Impact hammer trigger

    I'm collecting data of a built-in beam. I installed the test of impact labview module to acquire data with fmax 1200Hz, sampling frequency - 3000 Hz, to acquire data for about 0.9 seconds with a = 1.2 Hz frequency resolution.
    He shows me the impact when I run the software, but does not collect or store data. Finally, an error saying: trigger software has expired. Also, I put the number of samples to 2500, but I get a message that the samples must be greater than 0 which I can't understand.
    How am I suppose to collect data for impact at the time and he averaged? I tried N samples and run once options.

    If you could help me out with this it would be great. Thank you very much.

    Hi StuMtu,

    The two properties to set to clear the errors will be to increase the time-out in the step of trigger Setup tab. You must also make sure that you are going to be exciting the hammer than the level set out within this time limit, otherwise you will get the timeout error.

    The other error you receive should just happen when you try to set the number of samples to averageto zero. If you set a higher number, the error should disappear. If it still does not work, you can try putting a new stage with the appropriate settings to see if the error persists.

  • Test question of impact frequency

    Hi all:

    I'm trying to get the natural frequencies of some frames my company designs and I was wondering if there was a simple way to get this to the impact of the sample test of vi and display? Currently, I work with SVXMPL_Impact Test.vi and SVXMPL_Advanced Impact Test.vi and I am running Labview 2010 with the sound and vib add on.

    Andy

    Hi andy,.

    It seems that these example programs to find the frequency of the pulse signal. You can use the same .vi SVFA FFT (Mag Phase) spectrum used in the research of the frequency to find the frequency of the response signal. Once you have this signal, you can use the spectrum SVFA cutting-edge research to read the natural frequency from the frequency data.

  • Anonymous IIS and impersonation

    Simple configuration. Create a virtual machine with IIS and SQL Server, and Web (ASP.NET) application. All on the same machine without hops involved.

    IIS is set to anonymous authentication only (not asp.net impersonation).

    The site is configured with an application pool using a Local Windows of Custom account (\SQLDataAccess).

    SQL Server configured for the authentication of the window only.

    Permit SQLDataAccess to SQL Server. Confirmed by connecting to the machine as \SQLDataAccess and access to SQL server through SSMS.

    Now, the incoming request to IIS will be NT AUTHORITY\ANONYMOUS LOGON (is that correct, can anyone confirm?)

    I think this to be "borrowed" from \SQLDataAccess by the pool IIS application, and indeed in c# WindowsIdentity.GetCurrent (). Name returns \SQLDataAccess.

    But SQL Server reports "failed to connect to the user 'NT AUTHORITY\ANONYMOUS LOGON'. Reason: could not find a name of the connection corresponding to the provided name. »

    Is it because the Application Pool can only "flow the identity of the original caller back resources on the same computer?

    I also tried to set IIS configuration authenticatedUserOverride to UseWorkerProcessUser, but the results were the same.

    Is it so impossible to have an anonymous site IIS uses Windows authentication behind IIS?

    Thank you for the ideas.

  • Acceleration signal initial height under impact load - LabVIEW

    Hi all

    A hemispheric 10.6 kg strike ball weight a sample of concrete went the distance of 200 mm.

    The acceleration recorded using labview is illustrated below. Anyone know why I get this initial peak (ms 3 to 5.7) initially because acceleration must go down at impact?

    Thank you all.

    The test of the room shows an acceleration to rest of about 0 of + 20 when you deposit the coin.  I guess that the 1 g of gravity has been canceled, and that when the beam begins to descend, it is saved as an acceleration positive, right?  [Enter the right signs to something like this can be a real challenge!].

    I'm happy, I think that "the data is correct" was right.
