• Is Pex (Test generation) really usefull tool?

  - by Yauheni Sivukha

  Yes, it is possible to generate tests on boundary values for functions like "Sum" or "Divide". Pex is a good tool here. But more often we create tests on business behaviour. Let's consider example from classic Beck's tdd book: [Test] public void ShouldRoundOnCreation() { Money money = new Money(20.678); Assert.AreEqual(20.68,money.Amount); Assert.AreEqual(2068,money.Cents); } Can this test be generated? No :) 95 % of tests in my projects check business logic, and can not be generated. Pex (Especially in pair with Moles) can give 100% code coverage, but a high code coverage rate of a test suite does never indicate, that code is well tested - It only gives false confidence that everything is tested. And this is very dangerous. So, the question is - Is Pex really usefull tool?

• Where can an absolute beginner of Kohana PHP go to learn how to use it from the ground up?

  - by Sergio Tapia

  Hi guys! I have a month of free time and I've decided to launch my own website. It's going to be big and have dymanic content where different users with different roles can perform modifications to the site. Place comments, rate stores, list items, etc. This sound like a perfect opportunity for me to expand my horizons and learn a PHP Framework. I've used PHP bare bones before but nothing too complex. As of now, do you think Kohana is a mature framework to use? I've used Zend in the past for a course in Uni but it sucked horribly, I was new to the MVC model, but Zend had pretty much zero workable tutorials and guides for newbies. That's why I hated it. Where can I go to learn how to use Kohana from a retarded starting point? Thank you very much for your time.

• Rotating UIWebView with transform, content partially off screen, how to get it to stick on screen?

  - by jarmod

  I have a 320x416 portrait-shaped UIWebView filling a UIViewController's view. I also have a 90 degree rotate button that will transform the UIWebView through 90 degrees each time the button is touched. The code is basically: webView.transform = CGAffineTransformMakeRotation(touches%4 * M_PI/2.0); After rotation through 90 degrees, the now-landscape transformed UIWebView extends beyond both the left and right edges of the screen. In the process of applying the transformation, iPhone OS has changed the UIWebView's frame from {{0,0}, {320,416}} to {{-48,48}, {416,320}}. Don't have a problem with that. I then tweak the UIWebView's frame origin to (0,0) so that it starts top-left, but extends a little further beyond the right edge of the screen. Now, I can touch the UIWebView and pull it left to view the hidden information on the right but I cannot get the right-hand end to to stay on the screen -- the moment I untouch it, the right side bounces back off the screen. What is it that causes the view to bounce back off-screen? In other words, what is it that I need to tweak to allow either the left edge or the right edge to stick on the screen and remain visible (only one at a time, obviously)? Thanks.

• MouseMotion Sensor Method Call

  - by user321894

  I have a soon-to-be due assignment due in computer science. I have encountered a problem, for which no matter how long I study the API's of the class and superclasses, I can not figure out. Suppose I wish to design a sort of "Breakout game" where the mouse motion controls the motion of a block that is used to bounce a ball, which then destroys multi colored bricks. How do you specifically make the block "listen" to the mouse? The below code is what I have attempted to achieve the desired results. /** Breakout Program*/ public class Breakout extends GraphicsProgram implements MouseMotionListener { ... /** The Paddle Itself */ private GRect paddle = new GRect(0, HEIGHT-PADDLEBOTTOM_OFFSET, PADDLEWIDTH, PADDLEHEIGHT); ... /** Run the Breakout program. */ public void run() { paddle.setFillColor(Color.BLACK); paddle.setFilled(true); add(paddle); paddle.addMouseListener(this); ... } /** Move the horizontal middle of the paddle to the x-coordinate of the mouse position - * -but keep the paddle completely on the board. */ public void mouseMoved(MouseEvent e) { GPoint p= new GPoint(e.getPoint()); double x = p.getX(); paddle.setLocation(x, HEIGHT-PADDLEBOTTOM_OFFSET); } } Any clarification on why/what I am doing incorrectly would be helpful, thanks.

• Best Asp.net Hosting

  - by dotnetguts

  There are many asp.net web hosting companies which spends lot on advertisement and also gives you very cheaper rate, as low as $5, but when it comes to support they are simply hopeless. Everyone can you please pass your experience with your past hosting companies and suggest any good asp.net hosting company? Please consider following requirement factors Asp.net 3.5 or 4.0 supported. Url Rewriter support GZip support (Dynamic through code) Initial Setup support (If required) SQL Server 2005 or 2008 Allow to access SQL Server DB using SQL Mgmt Studio Environment supporting Backup and Restore of DB on my own, without involving tech support team Full Text Search support FTP support I can able to send atleast 500 Emails daily. 99.9% Up Time (No matter all web hosting say they have 99.9% Up Time, but its not true).

• Collision of dot and line in 2D space

  - by Anderiel

  So i'm trying to make my first game on android. The thing is i have a small moving ball and i want it to bounce from a line that i drew. For that i need to find if the x,y of the ball are also coordinates of one dot from the line. I tried to implement these equations about lines x=a1 + t*u1 y=a2 + t*u2 = (x-a1)/u1=(y-a2)/u2 (t=t which has to be if the point is on the line) where x and y are the coordinates im testing, dot[a1,a2] is a dot that is on the line and u(u1,u2) is the vector of the line. heres the code: public boolean Collided() { float u1 =Math.abs(Math.round(begin_X)-Math.round(end_X)); float u2 =Math.abs(Math.round(begin_Y)-Math.round(end_Y)); float t_x =Math.round((elect_X - begin_X)/u1); float t_y =Math.round((elect_Y - begin_Y)/u2); if(t_x==t_y) { return true; } else { return false; } } points [begin_X,end_X] and [begin_Y,end_Y] are the two points from the line and [elect_X,elect_Y] are the coordinates of the ball theoreticaly it should work, but in the reality the ball most of the time just goes straigth through the line or bounces somewhere else where it shouldnt

• How to render consistence and smooth moving animation on iphone / ipod / iphone simulator.

  - by shakthi

  I am trying render a simple animation(object movement animations) on iphone. I used opengl for object rendering. Movements appears to be smooth on the simulator. But if I used same code in the ipod, object movement is slower. In the iphone it is still slower. I googled a bit and found 'frame rate independent rendering method', which taught me the concept of 'time interval' and object movement based on it. However result is very unpleasant. There is a lot of jerk in the animation even when fps remains above 20. Following code fragment is used for calculation of time interval between successive frames and I am using that to move my animation. NSTimeInterval GetTimeIntervals(NSTimeInterval * inLastElapsedTime ) { NSTimeInterval intervalTime = 0; NSTimeInterval currentTime = [NSDate timeIntervalSinceReferenceDate]; if(*inLastElapsedTime != 0 ) { intervalTime = currentTime - *inLastElapsedTime; } *inLastElapsedTime = currentTime; return intervalTime; }

• How to optimize an database suggestion engine

  - by Dimitar Vouldjeff

  Hi, I`m making an online engine for item-to-item recommending movies. I have made some researches and I think that the best way to implement that is using pearson correlation and make a table with item1, item2 and correlation fields, but the problem is that after each rate of item I have to regenerate the correlation for in the worst case N records (where N is the number of items). Another think that I read is the following article, but I haven`t thought a way to implement it. So what is your suggestion to optimize this process? Or any other suggestions? Thanks.

• Optimizing MySQL statement with lot of count(row) an sum(row+row2)...

  - by Zombies

  I need to use InnoDB storage engine on a table with about 1mil or so records in it at any given time. It has records being inserted to it at a very fast rate, which are then dropped within a few days, maybe a week. The ping table has about a million rows, whereas the website table only about 10,000. My statement is this: select url from website ws, ping pi where ws.idproxy = pi.idproxy and pi.entrytime > curdate() - 3 and contentping+tcpping is not null group by url having sum(contentping+tcpping)/(count(*)-count(errortype)) < 500 and count(*) > 3 and count(errortype)/count(*) < .15 order by sum(contentping+tcpping)/(count(*)-count(errortype)) asc; I added an index on entrytime, yet no dice. Can anyone throw me a bone as to what I should consider to look into for basic optimization of this query. The result set is only like 200 rows, so I'm not getting killed there.

• Optimizing tiled maps in cocos2d-iphone

  - by Omega

  My cocos2d-iphone game has tiled maps. The tilesets textures are rather big. I got around 5 tilesets and each one is 2048x2048 (retina). My maps are around 80x80. They have around 8 layers and each one is obviously using one tileset. The frame rate falls (it goes around 30 sometimes. I know 30 is rather aceptable, but still, I want 50+). So given that textures are huge I can't afford to make many layers (since each one loads a texture of these). So how about I divide my tileset textures into much smaller tilesets (like 1024x1024 each)? That will allow me to use many more layers for my maps, right? Are there any other tips for huge retina display tile maps?

• How to make a secure login using UDID or device token?

  - by Erik B

  So I'm making an app where I want the users to be able add, edit and rate content, but I do not want to force them to register. Instead I was planning on just using their device id or device token to identify them. I'm planning on making both an iPhone and Android version, so I'm looking for a general solution, but the iPhone version has higher priority, so an iPhone specific solution would also be welcome. The problem is that I don't want just anyone to be able to use my web service by sending a phony device id or someone else's device id. How would the client prove to the server that it is providing the correct device id?

• More efficient way to find & tar millions of files

  - by Stu Thompson

  I've got a job running on my server at the command line prompt for a two days now: find data/ -name filepattern-*2009* -exec tar uf 2008.tar {} ; It is taking forever, and then some. Yes, there are millions of files in the target directory. But just running... find data/ -name filepattern-*2009* -print > filesOfInterest.txt ...takes only two hours or so. At the rate my job is running, it won't be finished for a couple of weeks.. That seems unreasonable. Is there a more efficient to do this? Maybe with a more complicated bash script? A secondary questions is "why is my current approach so slow?"

• How to stop the horizontal scrolling programmatically ?

  - by srikanth rongali

  I have a UITextView *textView in cocos2d's CCLayer. The text is scrolling in both the horizontal and vertical directions. But, I need it to scroll and bounce only in vertically. How to stop the horizontal scrolling programmatically ? UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(100,200, windowSize.height/2,windowSize.width/2)]; textView.backgroundColor = [UIColor clearColor]; textView.text = @"I am First enemy I am First enemy I am First enemy I am First enemy I am First enemy I am First enemy I am First enemy I am First enemy"; [textView setEditable:NO]; textView.font = [UIFont fontWithName:@"Helvetica" size:24.0f]; CGPoint location = CGPointMake(200, 160); textView.showsHorizontalScrollIndicator = NO; //textView.bounces = NO; //textView.alwaysBounceVertical = YES; textView.center = location; textView.transform = CGAffineTransformMakeRotation(CC_DEGREES_TO_RADIANS( 90.0f )); What should I do stop scrolling horizontally ? Thank You.

• Mysql - Grouping the result based on a mathematical operation and SUM() function

  - by SpikETidE

  Hi all... I'm having the following two tables... Table : room_type type_id type_name no_of_rooms max_guests rate 1 Type 1 15 2 1254 2 Type 2 10 1 3025 Table : reservation reservation_id start_date end_date room_type booked_rooms 1 2010-04-12 2010-04-15 1 8 2 2010-04-12 2010-04-15 1 2 Now... I have this query SELECT type_id, type_name FROM room_type WHERE id NOT IN (SELECT room_type FROM reservation WHERE start_date >= '$start_date' AND end_date <= '$end_date') What the query does is it selects the rooms that are not booked between the start date and end date. Also, as you can see from the reservation table, we also have 'number of rooms booked between the two dates' factor also... I need to add this 'no.of booked rooms between the two dates' factor also in to the query... The query should return the type of rooms for which at least one room is free between the two dates. I worked out the logic but just can't represent it as a query....! How will you do this...? Thanks for your suggestions..!

• Where to draw the line between efficiency and practicality

  - by dclowd9901

  I understand very well the need for websites' front ends to be coded and compressed as much as possible, however, I feel like I have more lax standards than others when it comes to practical applications. For instance, while I understand why some would, I don't see anything wrong with putting selectors in the <html> or <body> tags on a website with an expected small visitation rate. I would only do this for a cheap website for a small client, because I can't really justify the cost of time otherwise. So, that said, do you think it's okay to draw a line? Where do you draw yours?

• Why would an OS X bundle take about 30 seconds to open?

  - by Aftermathew

  Hi, We wrote a simple OS X executable in objective c. It opens and runs very quickly when called. We then put that executable into a .app bundle. When calling "open" from the command line on that bundle, or double clicking the app from the finder the "open" call can take upwards of 30 seconds to return. This is especially confusing because "open" clearly starts the executable right away (I can see it running in the process list right away, and have other indications that it's doing work), but when done from the command line, the "open" command takes a long time to return, and when done from the Finder the icon will bounce for a very long time before acting normal. I know the executable itself still opens very quickly because calling "open" on the executable inside my bundle returns very quickly, however calling it on the .app runs the code right away but takes 30 seconds or so to return. Has anyone run into this before? Do you have any suggestions for what could cause something like this? I've not been able to see anything funny in the bundle structure or the plist, but maybe I'm missing something. Thanks,

• OS X Dock API? Retrieve OS X active application's icon with badges and other modifications.

  - by pokstad

  Is there an API for retrieving the icons of the currently open apps on Mac OS X? I am trying to retrieve all the icons of the active applications along with any badges on top of the application (i.e. number of new messages in mail, or current download rate in Transmission). Is there some sort of Dock API? The only mention of an OSX API for retrieving information about currently active applications I have been able to find is the Process Manager API, which does not mention the ability to poll the dock or retrieve icon data.

• Real time video stream from camera via server to Iphone

  Hi I want to create an Iphone app that can display real time video from a camera. The intended setup is. Camera connected to Mac Mini delivering real time video to Iphone over local network. The Iphone doesn't need to display high quality or use a high frame rate, but it has to be real time. Max 1 sec delay. I've been searching a lot for a solution, but so far I have not found a resonable one. HTTP Live Stream is not a solution due to the delay. Any suggestions?

• Ruby: would using Fibers increase my DB insert throughput?

  - by Zombies

  Currently I am using Ruby 1.9.1 and the 'ruby-mysql' gem, which unlike the 'mysql' gem is written in ruby only. This is pretty slow actually, as it seems to insert at a rate of almost 1 per second (SLOOOOOWWWWWW). And I have a lot of inserts to make too, its pretty much what this script does ultamitely. I am using just 1 connection (since I am using just one thread). I am hoping to speed things up by creating a fiber that will create a new DB connection insert 1-3 records close the DB connection I would imagine launching 20-50 of these would greatly increase DB throughput. Am I correct to go along this route? I feel that this is the best option, as opposed to refactoring all of my DB code :(

• Looking for a file database

  - by Mitchell Skurnik

  A few years ago there was a PHP script around called paFileDB. Essentially it created a database of files that end users could download and rate. It would keep track of the number of downloads as well. I am looking for a replacement of this coded in ASP.net C#. For the last week I have been searching around for "asp.net C# file database" and have just gotten how to upload files to a database. I have also search with some other terms. I do not need a full blown CMS like DotNetNuke or SharePoint. All I have been looking for is a system I could easily add to my existing .net C# site. I have thought about coding one myself, but with me being rather busy at work and this being a personal project, I simply do not have the time to code this myself. I hope that you guys can help. Thank you!

• PHP APC - Why is loading cached array op codes slow?

  - by Aaron Kreider

  I'm using APC to reduce my loading time for my PHP files. My files load very fast, except for one file where I define more than 100 arrays. This 270 kb file takes 200 ms to load. The rest of the files are full of objects, methods, and functions. I'm wondering: does OP code caching not work as well for arrays? My APC cache should be big enough to handle all of my classes. Currently 40% of my cache is free. My hit rate is 99%. apc.shm_size=32 M apc.max_file_size = 1M apc.shm_segments= 1 APC 3.1.6 I'm using PHP 5.2, Apache 2, and Windows Vista.
