• SQLBeat Podcast – Episode 4 – Mark Rasmussen on Machine Guns,Jelly Fish and SQL Storage Engine

  - by SQLBeat

  In this this 4th SQLBeat Podcast I talk with fellow Dane Mark Rasmussen on SQL, machine guns and jelly fish fights; apparently they are common in our homeland. Who am I kidding, I am not Danish, but I try to be in this podcast. Also, we exchange knowledge on SQL Server storage engine particulars as well as some other “internals” like password hashes and contained databases. And then it just gets weird and awesome. There is lots of background noise from people who did not realize we were recording. And I call them out and make fun of them as they deserve; well just one person who is well known in these parts. I also learn the correct (almost) pronunciation of “fjord”. Seriously, a word with an “F” followed by a “J”. And there are always the hippies and hipsters to discuss. Should be fun.

• iPhone: Activate UISlider and set its value to the location of the current touch programatically

  - by carloe

  Is it possible to set an UISlider as first responder and set its current value to the location of the current touch programatically? The way my app is set up I have a UIView container that takes up the whole screen. Inside the container I have another UIView offscreen at the bottom edge (I'll call this bottomBar). Inside the bottomBar there is a UISlider element. Right now, when the user swipes along the bottom edge of the screen the bottomBar the slider it contains slide up. What I am trying to achieve is to activate the UISlider, and set the position of the slider (the value) to the position of the users touch. Is this possible? Could someone please point me in the right direction?

• Printing images in Flex

  - by TERACytE

  In s Flex 3 app, I have canvas with a PNG image for a background. The image is the same width & height as the canvas. I also have some other controls in the canvas: <mx:Canvas id="form" backgroundImage="@Embed(source='images/formBkg.png')" width="640" height="480" > <mx:label .../> <mx:label .../> I print the canvas using the following code: var printJob:FlexPrintJob = new FlexPrintJob(); if (printJob.start()) { printJob.addObject(form, FlexPrintJobScaleType.SHOW_ALL); printJob.send(); } On screen it looks great, but when I print it the quality of the png degrades. It is not terrible, but not as sharp as what is shown on screen. Is there anything I can do to improve the quality of the printed png?

• How Do I Detect A WordPress Admin Panel in my Plugin?

  - by Volomike

  I've got two events in my plugin. One is run for the front-end. The other is run for the admin panel. Both call the same function in one particular situation, and this echoes stuff to the screen. How do I make it such that the function is smart, calls something in WordPress, and detects whether it's being loaded in the front-end versus the admin panel? I don't want it to echo stuff to the screen on the front-end, but do want it to do so on the admin panel. Right now, it's echoing on both, which is not what I want. Background For the front end (the side of the site that the visitor sees), I'm intercepting the 'wp' event and checking for: ( is_single() || is_page() || is_home() || is_archive() || is_category() || is_tag()) For the admin panel, I'm intercepting the 'admin_menu' event. I tried intercepting the is_*() stuff above, but it seems to somehow answer TRUE or something, not giving me a difference between front-end and admin panel.

• Flash video hiding the cursor on Mac OS X

  - by Tibor

  I found a Core Graphics function, CGCursorIsVisible, that one can use to determine whether the mouse cursor is shown on screen. I have a small app that uses a timer to call that function a few times a second to see if the cursor is shown or hidden (as I found no way to get my app notified when the mouse cursor shown/hidden status changes). The above works correctly except… when the Flash browser plugin plays a video: the mouse cursor gets hidden after a few seconds of mouse inactivity but CGCursorIsVisible() still keeps telling me that the cursor is indeed shown as if nothing happened. What I need is to be able to tell, at any given moment, whether the mouse cursor is shown to the end user on any screen. Is there any way to do that even in the case of playing a video using the Flash plugin?

• Best code structure for arcade games

  - by user280454

  Hi, I've developed a few arcade games so far and have the following structure in almost all of them: I have 1 file which contains a class called kernel with the following functions: init() welcome_screen() menu_screen() help_Screen() play_game() end_screen() And another file, called Game, which basically calls all these functions and controls the flow of the game. Also, I have classes for different characters, whenever required. Is this a good code structure, or should I try having different files(classes) for different functions like welcome screen, playing, help screen, etc? As in, instead of including all the code for these things in 1 file, should I be having different classes for each one of them? The only problem I think it might cause is that I would need certain variables like score, characters, etc which are common to all of them, that's why I have all these functions in a Kernel class so that all these functions can use these variables.

• moving SDL video surface

  - by runrunraygun

  Does anyone know how to move my SDL.net video surface around the screen programtically? Surface videoContext = Video.SetVideoMode(1024, 768, 32, false, false, false, true, true); var a = System.Windows.Forms.Control.FromHandle(Video.WindowHandle); var b = System.Windows.Forms.NativeWindow.FromHandle(Video.WindowHandle); I can't find any properties in Surface or Video which do the job, and FromHandle is returning Null. The window is initializing falling off the bottom of the screen. Any ideas?

• Possible to Freeze Columns in a WPF ListView/GridView?

  - by Phil Sandler

  I currently have a GridView inside a ListView.View. The GridView columns will far exceed the width of the screen, so there will always be horizontal scrolling. What I would like to do is to have certain columns always remain on the screen regardless of scrolling. So the first x columns from the left are frozen (ala Excel), and the rest can scroll. It does not need to be dynamic/user selected--I know in advance which columns need to be frozen. Is this possible?

• Modify cmd.exe properties using the command prompt

  - by CodexArcanum

  Isn't that nicely recursive? I've got a portable command prompt on my external drive, and it has a nice .bat file to configure some initial settings, but I'd like more! Here's what I know how to set from .bat: Colors = (color XY) where x and y are hex digits for the predefined colors Prompt = (prompt $p$g) sets the prompt to "C:\etc\etc " the default prompt Title = (title "text") sets the window title to "text" Screen Size = (mode con: cols=XX lines=YY) sets the columns and lines size of the window Path = (SET PATH=%~d0\bin;%PATH%) sets up local path to my tools and appends the computer's path So that's all great. But there are a few settings I can't seem to set from the bat. Like, how would I set these up wihtout using the Properties dialogue: Buffer = not screen size, but the buffer Options like quick edit mode and autocomplete Popup colors Font. And can you use a font on the portable drive, or must it be installed to work? Command history options

• weird characters displayed during serial communication OSX

  - by nemo

  I have tried communicating via serial (OSX w/ prolific drivers - USB RS232 adapter - Tx,Rx and GND pins on device serial ttl port) to a device and done so successfully using screen /dev/tty.usbserial 115200 8N1 I get to log in and use it as if I was SSH or TelNetted in... However whenever I try to go into system recovery mode (holding CTRL+1) while the device is powering on, it starts displaying weird characters and until I close the screen session it will continue showing weird characters: Of course when we tried doing the same thing on my boss' macbook running windows and PuTTY and everything worked fine, even in system recovery mode; characters were displayed properly. What gives? Id like to learn the intuition to use because up till now I concluded that since I can bot into the system and see characters normally everything about the connection should be fine and its must have been the recovery partition that was broken. This was wrong of course... Niko

• Is SQL Azure a newbies springboard?

  - by jamiet

  Earlier today I was considering the various SQL Server platforms that are available today and I wondered aloud, wonder how long until the majority of #sqlserver newcomers use @sqlazure instead of installing locally Let me explain. My first experience of development was way back in the early 90s when I would crank open VBA in Access or Excel and start hammering out some code, usually by recording macros and looking at the code that they produced (sound familiar?). The reason was simple, Office was becoming ubiquitous so the barrier to entry was incredibly low and, save for a short hiatus at university, I’ve been developing on the Microsoft platform ever since. These days spend most of my time using SQL Server. I take a look at SQL Azure today I see a lot of similarities with those early experiences, the barrier to entry is low and getting lower. I don’t have to download some software or actually install anything other than a web browser in order to get myself a fully functioning SQL Server  database against which I can ostensibly start hammering out some code and I believe that to be incredibly empowering. Having said that there are still a few pretty high barriers, namely: I need to get out my credit card Its pretty useless without some development tools such as SQL Server Management Studio, which I do have to install. The second of those barriers will disappear pretty soon when Project Houston delivers a web-based admin and presentation tool for SQL Azure so that just leaves the matter of my having to use a credit card. If Microsoft have any sense at all then they will realise the huge potential of opening up a free, throttled version of SQL Azure for newbies to party on; they get to developers early (just like they did with me all those years ago) and it gives potential customers an opportunity to try-before-they-buy. Perhaps in 20 years time people will be talking about SQL Azure as being their first foray into the world of coding! @Jamiet Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• More efficient way of updating UI from Service than intents?

  - by Donal Rafferty

  I currently have a Service in Android that is a sample VOIP client so it listens out for SIP messages and if it recieves one it starts up an Activity screen with UI components. Then the following SIP messages determine what the Activity is to display on the screen. For example if its an incoming call it will display Answer or Reject or an outgoing call it will show a dialling screen. At the minute I use Intents to let the Activity know what state it should display. An example is as follows: Intent i = new Intent(); i.setAction(SIPEngine.SIP_TRYING_INTENT); i.putExtra("com.net.INCOMING", true); sendBroadcast(i); Intent x = new Intent(); x.setAction(CallManager.SIP_INCOMING_CALL_INTENT); sendBroadcast(x); Log.d("INTENT SENT", "INTENT SENT INCOMING CALL AFTER PROCESSINVITE"); So the activity will have a broadcast reciever registered for these intents and will switch its state according to the last intent it received. Sample code as follows: SipCallListener = new BroadcastReceiver(){ @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); if(SIPEngine.SIP_RINGING_INTENT.equals(action)){ Log.d("cda ", "Got RINGING action SIPENGINE"); ringingSetup(); } if(CallManager.SIP_INCOMING_CALL_INTENT.equals(action)){ Log.d("cda ", "Got PHONE RINGING action"); incomingCallSetup(); } } }; IntentFilter filter = new IntentFilter(CallManager.SIP_INCOMING_CALL_INTENT); filter.addAction(CallManager.SIP_RINGING_CALL_INTENT); registerReceiver(SipCallListener, filter); This works however it seems like it is not very efficient, the Intents will get broadcast system wide and Intents having to fire for different states seems like it could become inefficient the more I have to include as well as adding complexity. So I was wondering if there is a different more efficient and cleaner way to do this? Is there a way to keep Intents broadcasting only inside an application? Would callbacks be a better idea? If so why and in what way should they be implemented?

• Craftsmanship Tour Day 1: Didit Long Island

  - by Liam McLennan

  On Monday I was at Didit for my first ever craftsmanship visit. Didit seem to occupy a good part of a non-descript building in Rockville Centre Long Island. Since I had arrived early from Seattle I had some time to kill, so I stopped at the Rockville Diner on the corner of N Park Ave and Sunrise Hwy. I thoroughly enjoyed the pancakes and the friendly service. After walking to the Didit office I met Rik Dryfoos, the Didit Engineering Manager who organised my visit, and got the introduction to Didit and the work they are doing. I spent the morning in the room shared by the Didit developers, who are working on some fascinating deep engineering problems. After lunch at a local Thai place I setup a webcam to record an interview with Rik and Matt Roman (Didit VP of Engineering). I had a lot of trouble with the webcam, including losing several minutes of conversation, but in the end I was very happy the result. Here are the full interviews with Rik and Matt: Interview with Rik Dryfoos Interview with Matt Roman We had a great chat, much of which is captured in the recording. It was such great conversation that I almost missed my train to Manhattan. I’m sure Didit will continue to do well with such a dedicated and enthusiastic team. I sincerely thank them for hosting me for the day. If you are looking for a true agile environment and the opportunity to work with a high quality team then you should talk to Didit.

• width of a frustum at a given distance from the near plane

  - by structolite

  I'm using CML to manage the 3D math in an OpenGL-based interface project I'm making for work. I need to know the width of the viewing frustum at a given distance from the eye point, which is kept as a part of a 4x4 matrix that represents the camera. My goal is to position gui objects along the apparent edge of the viewport, but at some distance into the screen from the near clipping plane. CML has a function to extract the planes of the frustum, giving them back in Ax + By + Cz + D = 0 form. This frustum is perpendicular to the camera, which isn't necessarily aligned with the z axis of the perspective projection. I'd like to extract x and z coordinates so as to pin graphical elements to the sides of the screen at different distances from the camera. What is the best way to go about doing it? Thanks!

• Cheat sheet exhibiting bash shell stdout/stderr redirection behavior

Some examples I'd like to see covered: cmd > output_file.txt #redirect stdout to output_file.txt cmd 2> output_file.txt #redirect stderr to output_file.txt cmd >& outpout_file.txt #redirect both stderr and stdout to output_file.txt cmd1 | cmd2 #pipe cmd1 stdout to cmd2's stdin cmd1 2>&1 | cmd2 #pipe cmd1 stdout and stderr to cmd2's stdin cmd1 | tee result.txt #print cmd1's stdout to screen and also write to result.txt cmd1 2>&1 | tee result.txt #print stdout,stderr to screen while writing to result.txt (or we could just make this a community wiki and enumerate such things here) Thanks!

• Continual crashing in MKMapView annotationContainer:viewForAnnotation

  - by Oscar Goldman

  I've looked at other reports on this, and none seems to apply. Our app is being crippled by frequent (but not reliably reproducible) crashes like this: Reports of this turn up a lot on the Web, but many seem to go unsolved. I'm not doing anything crazy, just showing the user position and one marker on the map. I followed the examples I could find, and I've looked at the code for goofs but can't find any. Here's how my MapView delegate handles viewForAnnotation: The crash appears to be associated with a change in the user's location, but once the user-location marker is added, I don't mess with it. When I need to refresh the one other map marker, I skip the user marker when removing the other one: The delegate is the controller for the whole screen, so it's not being deallocated; the crash occurs while the screen is up. Not that it matters, but the map display looks like this: Any guesses or insight would be much appreciated! This is on iOS 5.0.1.

• What is the iPad user agent?

  - by Yoric

  Now that the iPad craze is officially open, it's time to think websites also for the iPad. From what I gather, the iPad is using iPhone OS, but with a different screen resolution from the iPhone/iPod touch. So suddenly, the assumption that iPhone OS = iPhone screen resolution becomes false. Sounds like many sites may have to revise their user-agent - css mapping. So, can anyone with access to the iPad or the iPad SDK give us the user-agent string? Thanks in advance.

• UISearchBar animation hidding button

  - by David Carvalho

  Hello I currently have a UISearchBar (attached to a UISearchDisplayController), but I reduced the width of the search bar so I could display a custom button to its right when the search bar is not selected. The button is used to access other views. However, when I select the search bar and then press cancel (or even perform a search) and return to the normal view, where the search bar should be displayed with my custom button, the search bar animates and takes up all the room for the button and the is not displayed. Essentially, the search bar takes up all the width of the screen when I only want it to take up a part of it. Is there any way to prevent the search bar from animating to the whole width of the screen? This is how I defined the CGRect of the search bar: self = [[UISearchBar alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 250.0f, 45.0f)] Any help would be great. Regards

• Thread not behaving correctly

  - by ivor

  Hello, I wonder if anyone can help me to understand where I could be going wrong with this code; Basically I'm working on a turorial and calling the class below from another class - and it is getting the following error; Exception in thread "Thread-1" java.lang.NullPointerException at org.newdawn.spaceinvaders.TCPChat.run(TCPChat.java:322) at java.lang.Thread.run(Unknown Source) I realise the error is beibg flagged in another class- but I have tested the other class with a small class which sets up a separate thread - and it works fine, but as soon as I try and implement a new thread in this class - it causes all sorts of problems. Am I setting up the thread correctly in this class? Basically I can set up a thread in this class, with a test loop and it's fine, but when I bring in the functionality of the rest of the game it sometimes hangs, or does not display at all. Any suggestions on where I could be going wrong would be greatly appreciated. Thanks for looking. package org.newdawn.spaceinvaders; import java.awt.BorderLayout; import java.awt.Canvas; import java.awt.Color; import java.awt.Dimension; import java.awt.FlowLayout; import java.awt.Graphics2D; import java.awt.GridLayout; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.event.KeyAdapter; import java.awt.event.KeyEvent; import java.awt.event.WindowAdapter; import java.awt.event.WindowEvent; import java.awt.image.BufferStrategy; import java.util.ArrayList; import java.util.Scanner; import java.awt.*;//maybe not needed import javax.swing.*;//maybenot needed import java.util.Random; //import java.io.*; /** * The main hook of our game.
