  • Optimize C# Code Fragment

    - by Eric J.
    I'm profiling some C# code. The method below is one of the most expensive ones. For the purpose of this question, assume that micro-optimization is the right thing to do. Is there an approach to improve performance of this method? Changing the input parameter to p to ulong[] would create a macro inefficiency. static ulong Fetch64(byte[] p, int ofs = 0) { unchecked { ulong result = p[0 + ofs] + ((ulong)p[1 + ofs] << 8) + ((ulong)p[2 + ofs] << 16) + ((ulong)p[3 + ofs] << 24) + ((ulong)p[4 + ofs] << 32) + ((ulong)p[5 + ofs] << 40) + ((ulong)p[6 + ofs] << 48) + ((ulong)p[7 + ofs] << 56); return result; } }

  • postgreSQL - pg_class question

    - by Sachin Chourasiya
    PostgreSQL stores statistics about tables in the system table called pg_class. The query planner accesses this table for every query. These statistics may only be updated using the analyze command. If the analyze command is not run often, the statistics in this table may not be accurate and the query planner may make poor decisions which can degrade system performance. Another strategy is for the query planner to generate these statistics for each query (including selects, inserts, updates, and deletes). This approach would allow the query planner to have the most up-to-date statistics possible. Why postgres always rely on pg_class instead?

  • Scrum metrics for quality

    - by zachary
    What is the best way to measure QA in scrum? We have members who typically test and they are measured against how many bugs they find. If they don't find any bugs then they are considered to be doing a bad job. However, it is my understanding that the developers and quality people are considered one in the same. I would think that they should be judged against the same metrics... not different metrics then the developers who may also be doing testing work... What is the best way to handle metrics for QA and should QA people have separate metrics from developers in scrum? Any documents or links someone can point me to in regards to this?

  • Support both Standard mode and Quirks mode? Is that possible and necessary?

    - by tshao
    Today I was assigned a bug saying that some page elements don't work on IE8 Quirks mode at all, and I need to fix them. The point is that I believe our pages will always be rendered in Standard mode, because we specify DOCTYPE at the beginning of every page (via master page). I'd think it must be some debugging tools changed that during testing. I managed to convice QA to close it as by design, after a brief explanation to her. Now I start to think the question that whether we should have our page work on both Standard and Quirks mode. Maybe we should try to minimize the problem even if the page is not rendering in a supposed mode? Any standard or best practices on that? Thanks!

  • Element point map for html5 canvas element, need algorithm

    - by Artiom Chilaru
    I'm currently working on a pure html 5 canvas implementation of the "flying tag cloud sphere", which many of you have undoubtedly seen as a flash object in some pages. The tags are drawn fine, and the performance is satisfactory, but there's one thing in the canvas element that's kind of breaking this idea: you can't identify the objects that you've drawn on a canvas, as it's just a simple flat "image".. What I have to do in this case is catch the click event, and try to "guess" which element was clicked. So I have to have some kind of matrix, which stores a link to a tag object for each pixel on the canvas, AND I have to update this matrix on every redraw. Now this sounds incredibly inefficient, and before I even start trying to implement this, I want to ask the community - is there some "well known" algorithm that would help me in this case? Or maybe I'm just missing something, and the answer is right behind the corner? :)

  • Notifying when screen is off

    - by Al
    I'm trying to generate a notification which vibrates the phone and plays a sound when the screen is off (cpu turned off). According to the Log messages, the notification is being sent, but the phone doesn't vibrate or play the sound until I turn the screen on again. I tried holding a 2 second temporary wakelock (PowerManager.PARTIAL_WAKE_LOCK), which I thought would be ample time for the notification to be played, but alas, it still doesn't. Any pointers to get the notification to run reliably? I'm testing this on an G1 running Android 1.6. Code I'm using: notif.vibrate = new long[] {100, 1000}; notif.defaults |= Notification.DEFAULT_SOUND; notif.ledARGB = Color.RED; notif.ledOnMS = 1; notif.ledOffMS = 0; notif.flags = Notification.FLAG_SHOW_LIGHTS; notif.flags |= NOTIF_FLAGS; //static var if (!screenOn) { //var which updates when screen turns off/on mWakeLock.acquire(2000); } manager.notify(NOTIF_ID, notif);

  • What would you use for deployment scripts in Java?

    - by Nadav
    Hi, I'm working on a Java web project that uses Maven to build its artifacts. At the end of the Maven build we have a few jar and war files that we need to deploy onto our development/testing environment. Right now we're using a pretty hefty Ant script that performs several tasks (on both Windows/Linux machines) Starts/Stops services Copies/deletes files Builds some stuff and then executes it Etc Ant does the job well - but the script is quickly getting very large, and to be honest, it feels inadequate for the task at hand. Are there other alternatives? I've heard of gant, but I'm not sure that's the right way to go. Thanks for helping!

  • Surface Detection in 2d Game?

    - by GamiShini
    I'm working on a 2D Platform game, and I was wondering what's the best (performance-wise) way to implement Surface (Collision) Detection. So far I'm thinking of constructing a list of level objects constructed of a list of lines, and I draw tiles along the lines. ( http://img375.imageshack.us/img375/1704/lines.png ). I'm thinking every object holds the ID of the surface that he walks on, in order to easily manipulate his y position while walking up/downhill. Something like this: //Player/MovableObject class MoveLeft() { this.Position.Y = Helper.GetSurfaceById(this.SurfaceId).GetYWhenXIs(this.Position.X) } So the logic I use to detect "droping/walking on surface" is a simple point (player's lower legs)-touches-line (surface) check (with some safety approximation - let`s say 1-2 pixels over the line). Is this approach OK? I`ve been having difficulty trying to find reading material for this problem, so feel free to drop links/advice.

  • Sending events to the dev version of a ruleset via HTTP

    - by Steve Nay
    I've been writing an endpoint that sends events to a KRL ruleset via HTTP GET (based on the documentation here), in this format: http://cs.kobj.net/blue/event/{domain}/{eventname}/{appid} That works great when the version of the app I want to test is the same one that's deployed. I don't always want to deploy before testing it, though. Using the stated format for calling the dev version doesn't work. It still calls the deployed version of my ruleset: http://cs.kobj.net/blue/event/{domain}/{eventname}/{appid}:kynetx_app_version=dev What am I doing wrong?

  • Removing DIVs in a jquery dialog

    - by Macinville
    I have a dialog window that uses a URL for its contents { function(){jQuery.ajax({'success':function(html) { jQuery('#menu_dialog').html(html); $('#menu_dialog').dialog('open'); $('#header').hide(); },'url':'/testing/index.php/menu','cache':false});return false;}; } What happens is that it was displaying the whole page, including the header, the footer,navigation menu,etc. What I want is for the dialog to only display the content inside the <content> tag. How can I remove the unnecessary divs in the dialog window?

  • Visual studio 'View in Browser' shortcut to specific page?

    - by WowtaH
    We are using Visual Studio 2008 and would like to know if there is a way to create a (keyboard or toolbar) shortcut for the 'View in Browser'-command, but with a specific page from a specific (loaded) project. We always start testing/debugging our app from "Somepage.aspx" from "Project-x". I would like to make a shortcut that does 'View in Browser' with this specific page/file, from this specific project. So even if I am currently working on another file in another project (from the same solution) it should still work... Anybody know if this is possible, and if so, how this can be achieved? Thanks! W.

  • What is the differnce between "LINQ to Entities", "LINQ to SQL" and "LINQ to Dataset".

    - by Marcel
    Hi all, I'm working for quite a while now with LINQ. However, it remained still a bit of a mystery what are the real differences between the mentioned flavours of LINQ. The successful answer will contain a short differentiation between them. What is the main goal if it, what is the benefit, and is there a performance impact... P.S. I know that there are a lot of information sources out there, but I look for a kind of a "cheat sheet" which instructs a newbie where to head to for a specific goal.

  • Is re-using a Command and Connection object in ado.net a legitimate way of reducing new object creat

    - by Neil Trodden
    The current way our application is written, involves creating a new connection and command object in every method that access our sqlite db. Considering we need it to run on a WM5 device, that is leading to hideous performance. Our plan is to use just one connection object per-thread but it's also occurred to us to use one global command object per-thread too. The benefit of this is it reduces the overhead on the garbage collector created by instantiating objects all over the place. I can't find any advice against doing this but wondered if anyone can answer definitively if this is a good or bad thing to do, and why?

  • WCF Rest services for use with the repository pattern?

    - by mark smith
    Hi there, I am considering moving my Service Layer and my data layer (repository pattern) to a WCF Rest service. So basically i would have my software installed locally (WPF client) which would call the Service Layer that exists via a Rest Service... The service layer would then call my data layer using a WCF Rest Service also OR maybe just call it via the DLL assembly I was hoping to understand what the performance would be like. Currently I have my datalayer and servicelayer installed locally via DLL Assemblies locally on the pc. Also i presume the WCF REST services won't support method overloading hance the same name but with a different signature?? I would really appreciate any feedback anyone can give. Thanks

  • Accessing database problem

    - by anarche
    Ok, so I've got an SQLiteOpenHelper that prepares and returns a SQLiteDatabase object; this is written singleton-pattern, so the database is opened once and only closed when the Activity closes. From there I have three database wrappers encapsulating the queries (some returning cursors to datasets, some inserting data) used by the Activity. I want to insert data from one View, then have that automatically update in another View on the same Dialogue. I'm writing this on a notepad and testing on the phone (since the emulator crashes the notepad...), so I can't pull up stacktraces atm. So questions: 1) are there limitations to writing to a database, when there are cursors open on the database? 2) Does a Cursor.requery()? call update the ListView with the cursor as a data connector?

  • C#: When should I use TryParse?

    - by zxcvbnm
    I understand it doesn't throw an Exception and because of that it might be sightly faster, but also, you're most likely using it to convert input to data you can use, so I don't think it's used so often to make that much of difference in terms of performance. Anyway, the examples I saw are all along the lines of an if/else block with TryParse, the else returning an error message. And to me, that's basically the same thing as using a try/catch block with the catch returning an error message. So, am I missing something? Is there a situation when this is actually useful?

  • What is my problem with ASP.NET pubslishing?

    - by Shankarooni
    I am done testing my site and I want to upload it to a site like this http://www.university.edu/mydepartment/myname the admin told me the server runs on .NET 3.5. So i used Linq ... now i tried to upload the site by two ways: when i just copy everything (with modification of web.config database settings) i get an error: CS0246: The type or namespace name 'DataClassesDataContext' could not be found (are you missing a using directive or an assembly reference?) Version Information: Microsoft .NET Framework Version:2.0.50727.3082; ASP.NET Version:2.0.50727.3082 Note here it says version 2.0 did he just lie to me? or its my configuration mistake? anyway, i added the reference, nothing changes. I tried also publishing (Build, publish) with option to keep the pre-comiled site updatable, and I get one line saying: this is a makefile and should be deleted! what is going on?

  • Entity data field validation and part data submission

    - by pradeeptp
    I have an entity class that has 10 fields. I am using MS Validation Application block to mark all fields as mandatory (IsRequired). I am implementing a securiy feature in which during updation of the data, not all the fields in the entity class will have data. For example a few users can only view 5 fileds while others all 10 fields during updation on GUI I have the following options 1) Bring all the data for all the fields from the DB table and hide the ones not accessible to the users in GUI. I am concerned about the performance because everytime GUI will pull unncessary data. 2) Bring the data (e.g. only 5 fields) that are permissible for access/view by the user on GUI. During submit, validation block will throw exception because all fields are marked as IsRequired and only data for 5 fields are sent back to the server. I want to know if there are any other good approaches to solve problems like this. I am using .NET 3.5 Thanks.

  • Passing ASP.NET User by Dependency Injection

    - by UpTheCreek
    In my web application I have various components that need to access the currently authenticated user (HttpContext.User). There are two obvious ways a component can access this: 1) Accessing getting the User from HttpContext.Current 2) Passing the user around in constructors Is not ideal because it makes testing difficult and ties application components to web concerns, when they really shouldn't know about it. Is just messy and complicates everything. So I've been thinking about passing in the current user (or perhaps just the name/id) to any component that needs it using an IoC container (via dependency injection). Is anyone using this technique to supply the current ASP.NET user to parts of the application? Or, Does this sound like a sensible approach? I would like know how this has worked out for people. Thanks

  • Selenium not finding LiveValidation text.

    - by McNabbToSkins
    I am using the Selenium IDE to test some of my web development. I am using the JQuery LiveValidation in my code. I have an input box with some javascript behind it that will do a regular expresson and either ouput "OK" or "Error" next to the input text box based on what the user has entered. For some reason when testing with selenium the LiveValidation will not get triggered no matter what I do and therefore I can not test it. When I do it manually it works great. Has anyone run into this problem before? Any help would be appreciated.

  • Using an image as a border

    - by Tempname
    I am working on an custom container and I need a border for this container. I have a 15x15 image that I am creating a 9-slice border skin with. The issue that I am having is that the border skin does not appear the way that I had hoped it would. Here is a ss of the skin in place. Ideally I should have a transparent box with a 5 pixel border around it. Here is my current testing code: CSS Code: Box { borderSkin: Embed(source="15x15.png", scaleGridLeft="5", scaleGridTop="5", scaleGridRight="10", scaleGridBottom="10"); } MXML Code: <mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Style source="MainTest.css"/> <mx:Box id="tw" width="400" height="400"> </mx:Box> </mx:WindowedApplication>

  • data between pages: $_SESSION vs. $_GET ?

    - by Haroldo
    Ok, firstly this is not about forms this is about consistent layout as a user explores a site. let me explain: If we imagine a (non-ajax) digital camera online store, say someone was on the DSLR section and specified to view the cameras in Gallery mode and order by price. They then click onto the Compact camera's page. It would be in the users interests if the 'views' they selected we're carried over to this new page. Now, i'd say use a session - am i wrong? are there performance issues i should be aware of for a few small session vars ( ie view=1 , orderby=price) ?

  • Determine if a string contains only alphanumeric characters (or a space)

    - by dreamlax
    I'm learning C++ and I am writing a function that determines whether a string contains only alphanumeric characters and spaces. I suppose I am effectively testing whether it matches the regular expression ^[[:alnum:] ]+$ but without using regular expressions. I have seen a lot of algorithms revolve around iterators, so I tried to find a solution that made use of iterators, and this is what I have: #include <algorithm> static inline bool is_not_alnum_space(char c) { return !(isalpha(c) || isdigit(c) || (c == ' ')); } bool string_is_valid(const std::string &str) { return find_if(str.begin(), str.end(), is_not_alnum_space) == str.end(); } Is there a better solution, or a “more C++” way to do this?
