    I have a website using Google analytics but it is counting way to much. To test this i was logging all entry's to my database with time and IP address. My result for one day was: Google analytics: Visits: 4078 Absolute Unique Visitors: 3758 My Database: Visits: 4182 Unique Visitors(Only by IP): 905 I use the tracking option "One domain with multiple subdomains" because the website is accessible both on www.example.com and example.com. I'm i missing something or what could be wrong?

  • Function like C# properties?

    - by alan2here
    I was directed here from SO as a better stack exchange site for this question. I've been thinking about the neatness and expression of C# properties over functions, although they only currently work where no parameters are used, and wondered. Is is possible, and if so why not, to have a stand alone function like C# property. For example: public class test { private byte n = 4; public test() { func = 2; byte n2 = func; func; } private byte func { get { return n; } set { n = value; } func { n++; } } } edit: Sorry for the vagueness first time round. I'm going to add some info and motivation. The 'n++' here is just a simple example, a placeholder, it's not intended to be representative of the actual code that would be used. I'm also looking at this from the point of view of looking at the property command as is, not in the context of using it for 'get_xyz' and 'set_xyz' member functions, which is certainly useful, but of instead comparing it more abstractly to functions and other programic elements. A 'get' property can be used instead of a function that takes no parameters, and syntactically they are perhaps only aesthetically, but as I see it noticeably nicer. However, properties also add the potential for an extra layer of polymorphism, one that relates to the 'func = 4;' getting, 'int n = func;' setting or 'func;' function like context in which they are used as well as the more common parameter based polymorphism. Potentially allowing for a lot of expression and contextual information reguarding how other would use your functions. As in many places uses and definitions would remain the same, it shouldn't break existing code. private byte func { get { } get bool { } set { } func { } func(bool) { } func(byte, myType) { } // etc... } So a read only function would look like this: private byte func { get { } } A normal function like this: private void func { func { } } A function with parameter polymorphism like this: private byte func { func(bool) { } func(byte, myType) { } } And a function that could return a value, or just compute, depending on the context it is used, that also has more conventional parameter polymorphism as well, like so: private byte func { get { } func(bool) { } func(byte, myType) { } }

  • Nifty popup fails to register

    - by Snailer
    I'm new to Nifty GUI, so I'm following a tutorial here for making popups. For now, I'm just trying to get a very basic "test" popup to show, but I get multiple errors and none of them make much sense. To show a popup, I believe it is necessary to first have a Nifty Screen already showing, which I do. So here is the ScreenController for the working Nifty Screen: public class WorkingScreen extends AbstractAppState implements ScreenController { //Main is my jme SimpleApplication private Main app; private Nifty nifty; private Screen screen; public WorkingScreen() {} public void equip(String slotstr) { int slot = Integer.valueOf(slotstr); System.out.println("Equipping item in slot "+slot); //Here's where it STOPS working. app.getPlayer().registerPopupScreen(nifty); System.out.println("Registered new popup"); Element ele = nifty.createPopup(app.getPlayer().POPUP); System.out.println("popup is " +ele); nifty.showPopup(nifty.getCurrentScreen(), ele.getId(), null); } @Override public void initialize(AppStateManager stateManager, Application app) { super.initialize(stateManager, app); this.app = (Main)app; } @Override public void update(float tpf) { /** jME update loop! */ } public void bind(Nifty nifty, Screen screen) { this.nifty = nifty; this.screen = screen; } When I call equip(0) the system prints Equipping item in slot 0, then a lot of errors and none of the subsequent println()'s. Clearly it botches somewhere in Player.registerPopupScreen(Nifty nifty). Here's the method: public final String POPUP = "Test Popup"; public void registerPopupScreen(Nifty nifty) { System.out.println("Attempting new popup"); PopupBuilder b = new PopupBuilder(POPUP) {{ childLayoutCenter(); backgroundColor("#000a"); panel(new PanelBuilder() {{ id("List"); childLayoutCenter(); height(percentage(75)); width(percentage(50)); control(new ButtonBuilder("TestButton") {{ label("TestButton"); width("120px"); height("40px"); align(Align.Center); }}); }}); }}; System.out.println("PopupBuilder success."); b.registerPopup(nifty); System.out.println("Registerpopup success."); } Because that first println() doesn't show, it looks like this method isn't even called at all! Edit After removing all calls on the Player object, the popup works. It seems I'm not "allowed" to access the player from the ScreenController. Unfortunate, since I need information on the player for the popup. Is there a workaround?

  • Self-Executing Anonymous Function vs Prototype

    - by Robotsushi
    In Javascript there are a few clearly prominent techniques for create and manage classes/namespaces in javascript. I am curious what situations warrant using one technique vs. the other. I want to pick one and stick with it moving forward. I write enterprise code that is maintained and shared across multiple teams, and I want to know what is the best practice when writing maintainable javascript ? I tend to prefer Self-Executing Anonymous Functions however I am curious what the community vote is on these techniques. Prototype : function obj() { } obj.prototype.test = function() { alert('Hello?'); }; var obj2 = new obj(); obj2.test(); Self-Closing Anonymous Function : //Self-Executing Anonymous Function (function( skillet, $, undefined ) { //Private Property var isHot = true; //Public Property skillet.ingredient = "Bacon Strips"; //Public Method skillet.fry = function() { var oliveOil; addItem( "\t\n Butter \n\t" ); addItem( oliveOil ); console.log( "Frying " + skillet.ingredient ); }; //Private Method function addItem( item ) { if ( item !== undefined ) { console.log( "Adding " + $.trim(item) ); } } }( window.skillet = window.skillet || {}, jQuery )); //Public Properties console.log( skillet.ingredient ); //Bacon Strips //Public Methods skillet.fry(); //Adding Butter & Fraying Bacon Strips //Adding a Public Property skillet.quantity = "12"; console.log( skillet.quantity ); //12 //Adding New Functionality to the Skillet (function( skillet, $, undefined ) { //Private Property var amountOfGrease = "1 Cup"; //Public Method skillet.toString = function() { console.log( skillet.quantity + " " + skillet.ingredient + " & " + amountOfGrease + " of Grease" ); console.log( isHot ? "Hot" : "Cold" ); }; }( window.skillet = window.skillet || {}, jQuery )); //end of skillet definition try { //12 Bacon Strips & 1 Cup of Grease skillet.toString(); //Throws Exception } catch( e ) { console.log( e.message ); //isHot is not defined } I feel that I should mention that the Self-Executing Anonymous Function is the pattern used by the jQuery team. Update When I asked this question I didn't truly see the importance of what I was trying to understand. The real issue at hand is whether or not to use new to create instances of your objects or to use patterns which do not require constructors of the use of the new keyword. I added my own answer, because in my opinion we should make use of patterns which don't use the new keyword. For more information please see my answer.

  • Converting NUnit tests to MSUnit.

    - by TATWORTH
    I created the MSTest project by creating a new class library project and copying the test classes to it. I then followed the instructions in the following posts.http://social.msdn.microsoft.com/Forums/en/vststest/thread/eeb42224-bc1f-476d-98b4-93d0daf44aadhttp://dangerz.blogspot.co.uk/2012/01/converting-nunit-to-mstest.htmlHowever I did not need to add the GUID fix as I used ReSharper to run both sets of tests.

  • Good, simple reasons for having multiple environments

    - by smp7d
    Throughout my career I had worked at companies that had a collection of different environments for different purposes. We always had more or less our desktop environment, a test environment, a QA environment, a staging environment and a production environment. This went for both servers/applications and any data sources we were using. When I started at my current company I found that 90% of the apps were either developed on a desktop environment against production data sources or developed directly on the production server depending on the platform. I wasn't fazed because I was hired in part to make changes to improve the way the development team functioned, which was clear from my interview process. We slowly started to turn the philosophy and pretty soon, most of the apps could be run in either a desktop, test or production environment. Not too long after that staging came around as well. Now most of our developers see the benefit of this methodology and defend it vigilantly. However, we have a number of legacy apps that never got migrated. We also have a number of legacy programmers who think of this as a waste of time. Unfortunately, we got lip service but never full buy-in from management. We got what we thought was a commitment to invest substantially in this about a year ago, but nothing materialized despite the considerable planning that we put into it. Now we are finding that we need more and more environments. We need help from the server/network administration teams for setup and we need participation from the business stakeholders to support the release cycle. We are at a place now where a project can function what I consider "normally" only if you have the right people on the project and the time to set up the proper environments. I'd love to present a complete argument, but management really has no time and interest in hearing me out until there is a critical issue. I can't really articulate the benefits simply as it always just seemed second nature to me. I was wondering if there are any good, simple, irrefutable reasons for the separation of environments that would get managers with no development experience to get behind this idea. Are there any good resources/literature on the topic?

  • Does the method of adjustment matter, or just the final calibration?

    - by Steve
    A company produces software (and hardware) that is used to both perform automatic adjustments on electronic test equipment as well as perform calibrations of the same equipment. The results of the calibrations are put onto a certificate of calibration that is sent to the customer along with the equipment. This calibration certificate states various conditions of the calibration, such as what hardware (models/serial numbers) and software (version) was used to perform the calibration, as well as things like environmental conditions, etc. Making the assumption that the software used to produce the data (and listed on the calibration certificate) used on the certificate of calibration must have gone through a "test/release" process and must be considered "released" software - does this also mean that the software used for adjustment must also be released? I believe that the method (software/environmental conditions/etc) used or present during adjustment doesn't matter, all that really matters is the end result of the calibration, the conditions present during the calibration, and whether or not the equipment was within the specifications. The real question I'm hoping to get answered: Is there a reputable source (e.g. NIST or somewhere similar) that addresses this question? (I have searched...) The thinking is that during high volume production runs, the "unreleased" system can be used to perform adjustments, as long as a released system is used to perform the calibrations, since the time required to perform the adjustments is much longer than the calibration. This unreleased system will eventually become released for use, but currently is not. Also, please not that there is a distinction between "adjustment" and "calibration". The definition from BIPM International vocabulary of metrology, 2.39: Operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties (of the calibrated instrument or secondary standard) and, in a second step, uses this information to establish a relation for obtaining a measurement result from an indication. Followed by NOTE 2 (emphasis in original text): Calibration should not be confused with adjustment of a measuring system, often mistakenly called "self-calibration", nor with verification of calibration As a side note, I'm not sure why this got down voted. It's regarding software and it's use before and after release for use. I believe there is a best practice that can be applied and this is (hopefully) not primarily opinion based.

  • How to chroot Ubuntu+1?

    - by jrg
    What is the recommended way to use chroot from Ubuntu Stable (in my case 11.04) with Ubuntu+1 (11.10)? Linked (but probably separate) is "Is there anything special that I need to do in order to get Xorg working?" Reason I ask is because I'd like to test a few GTK3 programs without losing my current (stable) Ubuntu, or having to get my data synced. I thought about maybe running a SSH server from 11.10 and then using SSH's X forwarding, but that seems rather cumbersome.

  • Oops, I left my kernel zone configuration behind!

    - by mgerdts
    Most people use boot environments to move in one direction.  A system starts with an initial installation and from time to time new boot environments are created - typically as a result of pkg update - and then the new BE is booted.  This post is of little interest to those people as no hackery is needed.  This post is about some mild hackery. During development, I commonly test different scenarios across multiple boot environments.  Many times, those tests aren't related to the act of configuring or installing zone and I so it's kinda handy to avoid the effort involved of zone configuration and installation.  A somewhat common order of operations is like the following: # beadm create -e golden -a test1 # reboot Once the system is running in the test1 BE, I install a kernel zone. # zonecfg -z a178 create -t SYSsolaris-kz # zoneadm -z a178 install Time passes, and I do all kinds of stuff to the test1 boot environment and want to test other scenarios in a clean boot environment.  So then I create a new one from my golden BE and reboot into it. # beadm create -e golden -a test2 # reboot Since the test2 BE was created from the golden BE, it doesn't have the configuration for the kernel zone that I configured and installed.  Getting that zone over to the test2 BE is pretty easy.  My test1 BE is really known as s11fixes-2. root@vzl-212:~# beadm mount s11fixes-2 /mnt root@vzl-212:~# zonecfg -R /mnt -z a178 export | zonecfg -z a178 -f - root@vzl-212:~# beadm unmount s11fixes-2 root@vzl-212:~# zoneadm -z a178 attach root@vzl-212:~# zoneadm -z a178 boot On the face of it, it would seem as though it would have been easier to just use zonecfg -z a178 create -t SYSolaris-kz within the test2 BE to get the new configuration over.  That would almost work, but it would have left behind the encryption key required for access to host data and any suspend image.  See solaris-kz(5) for more info on host data.  I very commonly have more complex configurations that contain many storage URIs and non-default resource controls.  Retyping them would be rather tedious.

  • Does anyone do hardware benchmarks on compiling code?

    - by Colen
    I've seen a bunch of sites that benchmark new hardware on gaming performance, zipping some files, encoding a movie, or whatever. Are there any that test the impact of new hardware (like SSDs, new CPUs, RAM speeds, or whatever) on compile and link speeds, either linux or windows? It'd be really good to find out what mattered the most for compile speed and be able to focus on that, instead of just extrapolating from other benchmarks.

  • A TDD Journey: 1-Trials and Tribulations

    Test-Driven Development (TDD) has a misleading name, because the objective is to design and specify that the system you are developing behaves in the ways that the customer expects, and to prove that it does so for the lifetime of the system. It isn't an intuitive way of coding but by automating the specifications of a system, we end up with tests and documentation as a by-product. Michael Sorens starts an introduction to TDD that is more of a journey in six parts:
