• Extracting a string starting with x and ending with y

  - by DMan

  First of all, I did a search on this and was able to find how to use something like String.Split() to extract the string based on a condition. I wasn't able to find however, how to extract it based on an ending condition as well. For example, I have a file with links to images: http://i594.photobucket.com/albums/tt27/34/444.jpghttp://i594.photobucket.com/albums/as/asfd/ghjk6.jpg You will notice that all the images start with http:// and end with .jpg. However, .jpg is succeeded by http:// without a space, making this a little more difficult. So basically I'm trying to find a way (Regex?) to extract a string from a string that starts with http:// and ends with .jpg

• shell script redirect output

  - by Andy

  I have a shell script to monitor process due to preventing the process closed. If the process is closed, that script will restart it. BTW, when the system starts, the crontab will run the script automatically. How can I get the output of the process which started by the shell script? #!/bin/bash PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:~/bin export PATH while : do if [ -z "$(ps -ef | grep -v grep | grep 225.0.6.4)" ]; then date +"%m-%d-%y %T" >> /home/andy/log/stream.log echo "225.0.6.4 - 103 not worked and restart process" >> /home/andy/log/stream.log echo "225.0.6.4 - 103 not worked and restart process" /usr/bin/tzap -a 1 -c /home/andy/channels.conf -o - -r -p "D" | /home/andy/ffmpeg -f mpegts -i pipe:0 -c:v libx264 -preset medium -crf 23 -bufsize 3000K -minrate 1200k -maxrate 1200k -pix_fmt yuv420p -g 50 -s 1024x768 -acodec libmp3lame -b:a 128k -ac 2 -ar 44100 -f mpegts udp://225.0.6.4:50000 & fi sleep 1 done

• Wrapper around bash, control STDIN and STDOUT

  - by blinry

  I would like to talk to a interactive bash process. Here is an example, so you know what I want to archieve: Program starts a new bash process. User types "ls" into my program. Program sends this command to the bash process. Program reads all available output of the bash (including the prompt) and displays it back to the user. GOTO 1 As you can guess, there is much room for nifty manipulations here and there... ;-) It would be wonderful if this also worked for subprocesses (started by the bash process) and curses-based programs. I would like to implement this functionality in Ruby, and already have experimented with IO.popen, but strange things happen. You are also welcome to do this in other languages.

• Show blank UITableViewCells in custom UITableView

  - by Typeoneerror

  I am trying to customize a UITableView. So far, it looks good. But when I use a custom UITableViewCell sub-class, I do not get the blank table cells when there's only 3 cells: Using the default TableView style I can get the repeating blank rows to fill the view (for example, the mail application has this). I tried to set a backgroundColor pattern on the UITableView to the same tile background: UIColor *color = [UIColor colorWithPatternImage:[UIImage imageNamed:@"score-cell-bg.png"]]; moneyTableView.backgroundColor = color; ...but the tile starts a bit before the TableView's top, so the tile is off once the actual cell's are done displaying: How can I customize my tableview but still keep the blank rows if there's less rows than fill a page?

• What happens before applicationDidFinishLaunching is invoked?

  - by nefsu

  I'm doing performance testing on my iphone app and I'm noticing that sometimes a good 3-4 secs elapse at startup before I start seeing my NSLogs from applicationDidFinishLaunching. I've optimized what happens once the code enters applicationDidFinishLaunching but I'm not sure how to optimize what goes on before that. I'm using a Default.png splash screen so it basically just stalls on that screen before it enters applicationDidFinishLaunching and starts doing something. Just to give you guys some context, I have no nib files and I'm using core animation, if that makes any difference. I have about 10 different controllers and my total bundle size is just under 2MBs.

• How to set AeDebug to get a minidump with the name of the process ?

  - by JC Martin

  I have to perform some post mortem debugging on a C++ project. Known way to perform is to set the cdb debugger as a minidump generator and to process the dumps collects afterwards. I read nearly the whole web and I didn't find a solution to produce a minidump with the name of the process that has crashed Is there a way to set AeDebug\Debugger registry variable in such a manner that cdb generates a dump file with the name of the process ? When I encapsulate the call to cdb.exe in a batch file, it starts well but stays blocked on the symbol searching. I must perform a Ctrl+C in order to stop the batch, then the minidump, with the correct process name, is created... but of course I can't set up such a thing in an unattended production environment... Has anybody done that before ?

• Can’t tap button after interface rotation

  - by zoul

  Hello! I’ve got a view that has to be presented both in landscape and portrait. The transition between different orientations is done by repositioning and resizing the subviews. One of the subviews is a button (plain UIButton with an image background). When the interface rotates to landscape, the button starts misbehaving – it can only be tapped on its left part, the right part does not respond. When I move the button a bit to the left, the tappable part grows. The button should not be obscured by any other view, it’s clearly visible. When I override the hitTest:withEvent: method in the parent view, I see that the taps in the “numb” part of the button result in nil being returned. I think I have seen this behaviour once before, but unfortunately I’ve forgotten the source of the problem :) Any help?

• ipad simulator error after distribution

  - by ghiboz

  Hi all, I developed a test app and I tried to use into the simulator.. all works fine! After, following the document "iPhone_developer_program_user_guide" I made the distribution version of my app (and xcode built it without problems). After this, I couldn't try the distribution 'cause I don't have iPad, but when I selected the debug type and relaunched to the simulator, the simulator starts, become all black and xcode give this error: I sent the .app and the .mobileprovision to my mate that have the iPad (configured with the udid) and retrieve an unknown error (0xE8008001)... thanks in advance!

• Embedded AXIS2: Serving a custom WSDL

  - by Maik

  I am using a console app that starts several axis instances without using a packages archive. Like this: AxisService axisService2 = AxisService.createService( new Myclass.getClass().getName(), axisConfigurationContext.getAxisConfiguration()); axisService2.addParameter(new Parameter("useOriginalwsdl", "true")); axisConfigurationContext.getAxisConfiguration().addService(axisService2); Now, I need to serve a custom WSDL. I tried adding a META-INF folder to the bin-root, and in various other places, but with no success. How do I specify in this case the location of a custom WSDL? Thanks!

• iPhone link to map directions using string "current location" not lat and lng for saddr

  - by Nick

  I know there are numerous questions about how to construct a sharedApplication link to the maps app specifying the start and end address with coordinates. I've got that working no problem. Has anyone found a way to link with a source address generically specified as "current location". I ask because the scenario I'm working on having Core Location or a UIMapView would only be necessary in order to determine the user location prior to handing off to the map app where the user locating would seem to just happen again. I've tried throwing UTF8'd "Current Location" and "[Current Location]" into the saddr parameter which amusingly starts from Current Montana. I've also tried simply excluding the saddr param. I know this is often tread territory but this particular situation wasn't covered by anything I found searching here or on mapki. Before I add the core location code I just wanted to make sure there wasn't a more limited way to tackle this. Thanks

• What's a good tutorial for creating a gem with RSpec?

  - by ramon.tayag

  I've been searching around for ways to create a gem with RSpec, but haven't found descriptive tutorials. I started out with Ryan Bates' Making a gem, but I'm looking for a tutorial that discusses creating an acts_as style gem with RSpec. By acts_as, I mean to say that the gem adds certain methods to an existing class in Rails. Why is this important? Because I've found gem templates like New Gem, got a spec to run but when I try to test an Active Record object it starts choking. I've tried requiring active_record in spec_helper.rb but I must be doing something wrong because it doesn't solve the problem. When it comes to plugins, I found this Rails Guide. If there's a gem version for that around that'd be awesome. Thanks guys! P.S. I love screencasts.

• ActiveX controls with old Delphi versions

  - by DamienD

  I'm testing a non visual ActiveX control based on a registered .ocx which I import into Delphi using the provided wizard. Then, I simply put the generated component on the main form of a new VCL application. Under old Delphi versions (D5 and D2007), when i launch the application, this raise an AV during the component initialization. with Delphi 2009 : no problem, the application starts smoothly. My questions are : Are there known enhancements of ActiveX management in recent Delphi versions which can explain this difference ? Can I suspect a bug in the ActiveX control, or can I consider the origin of the problem is from old Delphi versions ? I need to use this component (if tests OK) in D2007. Do you think that it is possible to correct the AV problem under D2007 by modifying the D2007 generated .tlb file (for example by trying to use the D2009 generated one) PS: the ActiveX control is not named, because my question is a general question about Delphi and ActiveX, not about a specific ActiveX control.

• Is anyone else experiencing weird debug + crash behavior with Silverlight?

  - by Scott Barnes

  I have noticed that after awhile of debug/tweakcode/debug etc that eventually Silverlight starts to crash all of my browsers (i.e. doesn't matter which i fire, they all just crash). If i then go to a site that has Silverlight, it works fine? so it has something to do with debugger + Silverlight not getting along? I then reboot and the problem goes away? Is anyone else experiencing this kind of weird behaviour? I have noticed though that if i put breakpoints on the code they all seem to halt, in that it appears that it can instantiate the said .xap etc ok, but just can't seem to render it to screen without a crash? (There's nothing in the log files and i've tried to attach a seperate VS2008 instance to both IE, Devenv and Blend etc trying to see if i can catch what's causing this to occur?)

• Java Loop every minute.

  - by Robert

  I want to write a loop in Java that firs starts up and goes like this: while (!x){ //wait one minute or two //execute code } I want to do this so that it does not use up system resources. What is actually going on in the code is that it goes to a website and checks to see if something is done, if it is not done, it should wait another minute until it checks again, and when its done it just moves on. Is their anyway to do this in java? I googled it but didnt find anything. Thanks

• Storing old previous year data in Rails?

  - by Millisami

  Hi, I'm developing an app which has massive data entries. Its like Campaign which has attrs like rate_per_sq_feet, start_date, end_date. i.e it will have max date of around 30 days. Once the campaign is finished, its done and another starts. Now I'm confused that how to store those campaigns as reports so that its not accessed regurlarly. What I mean is to store in such a way that it will act like report on later years to come? Its something like fiscal year on accounts where the previous year reports are stored with all the calculations done so that when retrieved later, all the algorithms and calculations shouldn't be performed. Something like frozen data??

• Controlling maximum Java standalone running in Linux

  - by Gnanam

  Hi, We've developed a Java standalone program. We've configured in our Linux (RedHat ES 4) cron schedule to execute this Java standalone every 10 minutes. Each standalone may sometime take more than 1 hour to complete, or sometime it may complete even within 5 minutes. My problem/solution I'm looking for is, the number of Java standalones executing at any time should not exceed, for example, 5 threads. So, for example, before even a Java standalone/thread starts, if there are already 5 threads running, then this thread should not be started; otherwise this would indirectly start creating OutOfMemoryError problems. How do I control this? I would also like to make this 5 thread as configurable. Other Information: I've also configured -Xms and -Xmx heap size settings. Is there any tool/mechanism by which we can control this? I also heard about Java Service Wrapper. What is this all about?

• Video not playing in IE in hidden div using JW Player, SWFObject and FancyZoom

  - by lgomez

  Hi all, I have a video that is meant to start playing when a user clicks on an image and said image opens a FancyZoom overlay. It works fine in every browser except IEs. If I place the video in a div that is not hidden (display:none actually), the video starts as expected. So it seems there is a problem with either Flash, JW Player, SWFObject or any combination of these when trying to load a video in a hidden div. Anyone know any workarounds? I tried modifying the FancyZoom library (see my fork: http://github.com/lgomez/fancy-zoom/blob/master/prototype/js/fancyzoom.js) so I could use a callback to inject the video AFTER the zoom effect was completed but that did'n work. Thanks!

• Parsing JPEG file format: Format of entropy-coded segment (ECS) segments?

  - by me2

  I'm having difficulty understanding the ITU-T T.81 spec for the JPEG file format. Hopefully someone else here has tried to parse JPEG files and/or knows about the details of this file format. The spec indiates that the ECS0 segment starts after the SOS segment but I can't find where in the spec it actually talks about the format of the ECS0 segment or how do detect its start. Simple JPEG implementations online are of limited help because they assume many things about the JPEGs they parse. Can anyone point me in the right direction?

• Xcode 3.2 + LLVM = no local symbols when debugging

  - by glebd

  I have a project for Mac OS X 10.5 that I'm building on 10.6 using Xcode 3.2. When I use GCC 4.2 for Debug build and hit a breakpoint, Xcode debugger displays local variable information normally. If I choose LLVM GCC 4.2 or Clang LLVM, when I hit breakpoint, local symbols are not available, and GDB says No symbol 'self' in current context if I try to print self or any other local symbol. In all cases Generate debug info option is set. The Debug configuration is set to $(NATIVE_ARCH) and 10.5 SDK, Build active architecture only option is set. When GDB starts, I can see it is being configured as x86_64-apple-darwin. I must be missing something obvious. How do I make GDB show local symbols when using a LLVM compiler?

• Modal View Controller with keyboard on landscape iPad changes location when dismissed

  - by Roi

  I present a modal view controller on my on my iPad with UIModalPresentationFormSheet presentation style and UIModalTransitionStyleCoverVertical transition style. The Modal View Controller contains a UIWebView with some TextFields on it. When the user taps one of the text fields the keyboard comes up. I have noticed that in landscape mode after the keyboard is shown, if I try to dismiss the modal view controller with animation the view changes its position from the center of the screen to the left side just before the animation starts.. This happens only if the keyboard is up and only in landscape mode on the iPad. If the user closes the modal view without pressing on any text field this doesn't happen. Anyone familiar with this strange behavior?
