• Pre loaded database on iPhone?

  - by Julian

  Hi, I have recently developed an app using core data as the storage db. The app allowed the user to read and write to the db. I am now developing a new app which the user doesnt need to write anything to the db, instead the app just needs to read the data. The data has relationships etc so cannot just use a plist or something similar. My question is should I use core data for such a requirement and if so how would i go about entering the data and then releasing the app. Would I have to code the data entry which would populate the db then remove all this code (as I dont want the database to repopulate every time the user opens the app)?? Is there a way to create a core data model using sql commands as with sqlite ie insert into..... etc? Any ideas/thoughts would be very helpful. Many thanks Jules

• Cocoa Launch agent registering itself after installation.

  - by Unicorn

  I have created Cocoa app which is type of launch agent. To distribute this I have created package as well which installs the app and copies the launchagnet plist file in /Libraries/LaunchAgents. Now the problem is after installation i want this app to be running in user context immediately without logoff/restart. If I register this with "launchctl" from installer, using post install script, it run in root context, as installer is running in root context. Any suggestion how the agent registers itself to launchctl and runs in user context.

• How to flush coverage data when my test cause app crash - For ios app

  - by Ypy

  I want to get the code coverage of my tests. So I set the settings, build an app with .gcno files and run it on simulator. It can get the coverage data successfully if there is no crash issue. But if the app crashed, I will get nothing. So how can I get the code coverage data when the app crash? In my thought, this is because it will not call __gcov_flush() method when app crash. I only add app does not run in background to my plist file, so __gcov_flush() is called only at the time I press Home button. Is there any way to call __gcov_flush() before the app crash?

• Save NSCache Contents to Disk

  - by Cory Imdieke

  I'm writing an app that needs to keep an in-memory cache of a bunch of objects, but that doesn't get out of hand so I'm planning on using NSCache to store it all. Looks like it will take care of purging and such for me, which is fantastic. I'd also like to persist the cache between launches, so I need to write the cache data to disk. Is there an easy way to save the NSCache contents to a plist or something? Are there perhaps better ways to accomplish this using something other than NSCache? This app will be on the iPhone, so I'll need only classes that are available in iOS 4+ and not just OS X. Thanks!

• Proper way to handle issue when porting 32 to 64 bit. Conversion from DT1 to DT2 of greater size

  - by grobartn

  So I am trying to port 32 bit to 64 bit. I have turned on the VS2008 flag for detecting problems with 64 bit. I am trying following: char * pList = (char *)uiTmp); warning C4312: 'type cast' : conversion from 'unsigned int' to 'char *' of greater size Disregard the code itself. This is also true for any pointer, because 64 bit pointer is greater than 32 bit unsigned int or int for that purpose. Given that you have to cast smaller type to greater how would you go about doing it so it correctly on both 32/64 bit systems

• Adding text labels to sliders in iPhone Settings application

  - by Kevin L.

  When configuring a Settings.bundle as part of an iPhone application bundle, it's trivial to add minimum and maximum value images to sliders (PSSliderSpecifier), but not simple maximum and minimum text labels. http://developer.apple.com/iPhone/library/documentation/PreferenceSettings/Conceptual/SettingsApplicationSchemaReference/Articles/PSSliderSpecifier.html iPhone gurus: Is anyone aware of a simple means to apply text labels to these sliders for use within the Settings application (therefore, no slider subclassing shenanigans; it all has to be done via a plist)? I suppose I could just use an image of the label but...ew. Bonus points if there's a way to show the current value of a slider in some sort of number format.

• How to temporarily change all default user settings without destroying the original?

  - by mystify

  My app is based strongly on a lot of NSUserDefault keys and values. I want to implement a temporary defaults profile which the user can activate to get a special task done easily. For this, some of the user defaults must be changed temporarily so the app adjusts it's interface appropriately. I started to just manually change those NSUserDefaults settings, but this also destroys the user's original settings. Is it possible to keep a backup of the user's NSUserDefault settings and restore them after the user quits the temporary mode or the app? Like I see it, NSUserDefaults actually is just an NSMutableDictionary which is generated out of a plist file. So I would just make a deep copy of that and later assign that copy somehow back to NSUserDefaults?

• NSUserDefaults with in-app Settings bundle

  - by Hema Vasudevan

  I'm in the process of building an app and would prefer to have an in-app specific Settings bundle rather than make it available in the Settings application. I'm using NSUserDefaults class to save and retrieve them but would like to have the same Settings app look and feel. I wanted to use InAppSettingsKit or the llamasettings but don't know how to use the NSUserDefaults class. Those kits tell me how to create a .plist file and use their kits. All I need is use the Settings app look and feel while at the same time use NSUserDefaults class to save and retrieve values. Please help.

• download a complete folder

  - by Christian

  Hi, in my app I use several png-graphics. For the present version they are installed with the app in the folder "graphic". I made while programming. Now I need some more png-graphics and I don't want to make each time an app-update. How can I manage it, that the app is downloading the png-files from my webserver without knowing the name. I am looking for something which compares the files on the webserver with the files on the iPhone and if there is a new (or newer) file download it. Or is it possible to make an plist-file with the graphics??

• App Crashes on Opening - PROBLEM

  - by Guest

  I have an app that keeps crashing as soon as it starts. Not sure why. I have image views and buttons in the main xib file. The main xib file is not mainwindow, it is firstview, so i changed it in the plist to the firstview. There may be something wrong with the xib file for firstview but it only has buttons and images and a view in the back. There are no warnings or errors when I run it, just Debugging Terminated when it crashes. PLEASE HELP

• Why is iPhone 5 briefly Letterboxing and displaying Default.png in Cocos2d?

  - by The Learner

  I have [email protected] which loads fine. However, (on the actual device) after it shows the iPhone 5 then displays Default.png, in letter box mode. It then loads the 1136 × 640 px Title Screen - which is fine and what it's supposed to do. I'm using the default Cocos2d HelloWorld template. I haven't changed anything in the plist or otherwise. Any ideas? Why does it load the Default.png and how do you fix this? Thanks. In the IntroLayer we have -(void) onEnter if( UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone ) { background = [CCSprite spriteWithFile:@"Default.png"]; background.rotation = 90; } Which is why Default.png is showing up. How do you keep showing [email protected] if you are using the iPhone 5?

• How to read oom-killer syslog messages?

  - by Grant

  I have a Ubuntu 12.04 server which sometimes dies completely - no SSH, no ping, nothing until it is physically rebooted. After the reboot, I see in syslog that the oom-killer killed, well, pretty much everything. There's a lot of detailed memory usage information in them. How do I read these logs to see what caused the OOM issue? The server has far more memory than it needs, so it shouldn't be running out of memory.

  I have followed this tutorial about setting up an OpenVPN Server on Windows Server - and a client on Windows (in this case Windows 8). The server appears to be running fine - but it is not connecting with this error: Mon Jul 22 19:09:04 2013 Warning: cannot open --log file: C:\Program Files\OpenVPN\log\my-laptop.log: Access is denied.

• Failling install Ralink RT5592 driver on Ubuntu 14.04 LTS

  - by atisou

  My problem concerns the installation of a wi-fi driver (RT5592) for my new wi-fi adapter (PCE-N53) on my newly built computer. Basically, I don't manage to get the driver installed and therefore I cannot get the wifi to work. I know I am not the only one having this issue this year, between RT5592 driver and Ubuntu 14.04 LTS, in one way or the other. Is there anybody who has ever been able to fix this problem? It does not look like on all the posts I have been through... Following an answer to a same problem as mine (I was getting the same error message as Christopher Kyle Horton of "incompatible types" etc), I have applied the instructions and done the editings in a script as suggested by Paul B. Unfortunately I still do get error/warnings message (a different one this time) at the end of the make and the wi-fi still does not work. Below is a snapshot of the end of the message: In file included from /home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/include/os/rt_linux.h:31:0, from /home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/include/rtmp_os.h:44, from /home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/include/rtmp_comm.h:69, from /home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/os/linux/../../os/linux/pci_main_dev.c:31: include/linux/module.h:88:32: error: ‘__mod_pci_device_table’ aliased to undefined symbol ‘rt2860_pci_tbl’ extern const struct gtype##_id __mod_##gtype##_table \ ^ include/linux/module.h:146:3: note: in expansion of macro ‘MODULE_GENERIC_TABLE’ MODULE_GENERIC_TABLE(type##_device,name) ^ /home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/os/linux/../../os/linux/pci_main_dev.c:73:1: note: in expansion of macro ‘MODULE_DEVICE_TABLE’ MODULE_DEVICE_TABLE(pci, rt2860_pci_tbl); ^ cc1: some warnings being treated as errors make[2]: *** [/home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/os/linux/../../os/linux/pci_main_dev.o] Error 1 make[1]: *** [_module_/home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/os/linux] Error 2 make[1]: Leaving directory `/usr/src/linux-headers-3.13.0-32-generic' make: *** [LINUX] Error 2 The full pastebin data: paste.ubuntu.com/8088834/ It looks from the message that one would need to edit manually some of/other scripts in the driver package, as did Paul B suggest in one case. But I have no idea how to do that. Here is the driver package of the wifi adapter: www.asus.com/uk/Networking/PCEN53/HelpDesk_Download/ My system is as following: OS: ubuntu 14.04 LTS wi-fi card: Asus PCE-N53 motherboard: Asus KCMA-D8 processor: AMD Opteron 4228 HE kernel: 3.13.0-32-generic Following this info from chili555 in here, below are some extra info about my system: lspci -nn | grep 0280 gives 04:00.0 Network controller [0280]: Ralink corp. RT5592 PCI2 Wireless Network Adapater [1814:5592] and sudo apt-get install linux-headers-generic returns linux-headers-generic is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. If this is a kernel version (I have 3.13.0-32-generic) incompatibility issue with the driver as chilli555 suggests (the README file in the driver package says indeed it is compatible with kernel 2.6), how could one trick this around to make it work? that should be possible right? On ubuntu forums, the patches proposed dont work (leads the computer to freeze). Basically: is there anybody out there who has ever been able to make a PCE-N53 work on Ubuntu 14.04 LTS (kernel 3.13)? how shall I edit the driver package to make it work for my kernel?

• Silverlight Cream for April 29, 2010 -- #851

  - by Dave Campbell

  In this Issue: Carlos Figueira(-2-), Subodh Pushpak, Gergely Orosz, John Papa, Mike Snow(-2-), Rishi, Tim Heuer, Stefan Olson, and David Anson. Shoutouts: Josh Holmes blogged about a cool app the City of Miami has up: Miami 311: Built on Windows Azure Gergely Orosz reports on the state of a bug he found pre SL4: Silverlight 4 still displays large elements incorrectly Laura Foy and Charlie Kindel discuss WP7 on Channel 9: Windows Phone 7 Developer Tools Refresh Announced Charlie Kindel has an announcement, good instructions, and what's new notes on the Windows Phone Developer Tools CTP Refresh! Tim Heuer mentioned the workaround for this in his post (below), but I thought you might like to read Brandon Watson's debrief of what it's all about: Signed Assemblies Bug in the Windows Phone Tools CTP Refresh Laurent Bugnion posted about interrelations between versions of Blend and WP7 code... read it closely: Be careful when installing the Blend Windows Phone 7 Add-In From SilverlightCream.com: Consuming REST/POX services in Silverlight 4 Carlos Figueira has a pair of posts up about consuming services in Silverlight 4. This first one is about consuming REST/POX services. He provides a Service Contract that can be used with either and the full project code is available as well. Consuming REST/JSON services in Silverlight 4 In the second post, Carlos Figueira provides the code to allow WCF and Silverlight 4 to consume strongly-typed REST/JSON... and again, all the code is available. Silverlight and WCF caching Subodh Pushpak has a post up discussing caching in WCF, and has code demonstrating turning caching on at run-time. Detecting Silverlight Version Installed Gergely Orosz said it right when he said "Detecting the Silverlight version installed on a client machine isn’t entirely straightforward." ... and after reading this post, if you take the link to his ScottLogic blog, you'll get a full break-out of how it's done. Silverlight TV 22: Tim Heuer on Extending the SMF It's Thursday, and that means Silverlight TV! ... this week, John Papa has on Tim Heuer who has always been out there pushing media... and he's talking about SMF or Silverlight Media Framework for the uninitiated, and also extending it. Silverlight Tip of the Day #7 – Localized Resources Mike Snow has Tip Number 7 up and it's about localization... good end-to-end discussion and demonstration. Just thought I should use that to prove to my daughter that the tatoo she had put on the back of her neck actually reads "Eat More Broccoli" :) Silverlight Tip of the Day #8 – Detecting Alt, Shift, Control, Window & Apple Keys Combinations I just realized Mike Snow's site logo reads "Silverlight Tips of the Day" (bolding mine) ... that answers why I'm seeing more than one -- sorry Mike, couldn't pass it up :) ... Mike's second tip today and number 8 in the series is on detecting all the mouse button and ctl/alt/shift combinations in Silverlight. nRoute: More Wholesomeness, with SL 4 and .NET 4.0 Rishi has a post up announcing a new nRoute release for Silverlight 4 and .NET 4.0 He's tweaked the code to take advantages of enhancements in the new platforms, so check it out. Windows Phone 7 Developer Tools April 2010 Refresh Booya... Tim Heuer announced the release of the next drop in the WP7 tools ... dang wish I was at home today :) ... be sure to read the post for info such as the notes about Authenticode Assemblies and the release notes. Updates to Silverlight Multi-binding support Stefan Olson points up a SL4 change to Multi-binding support that he had previously blogged about. He shows the previous non-working example, and what you have to do to make it work now. Using XAML to create a custom wallpaper image for your mobile device David Anson has a solution for those pesky lost devices, and let me go on the record right now saying if anyone finds a WP7 phone laying around, just call me, it's mine :) [think that'd work??] ... ok, David's solution is a WPF app "MobileDeviceHomeScreenMaker" that you get the info set and it produces a png you then put on your device. But seriously about that lost phone... Stay in the 'Light!

• Having Fun with Coding4Fun&rsquo;s Windows Phone 7 Controls

  - by mbcrump

  I’m a big believer in having a hobby project as you can probably tell from the first sentence in my “personal webpage using Silverlight” article. One of my current hobby projects is to re-do my current WP7 application in the marketplace. I knew up front that I needed a “Loading” animation and a better “About” box. After starting to develop my own, I noticed a great set of WP7 controls by Coding4Fun and decided to use them in my new application. Before I go any further they are FREE and Open-Source. It is really simple to get started, just go to the CodePlex site and click the download button. After you have downloaded it then extract it to a Folder and you will have 4 DLL files. They are listed below: Now create a Windows Phone 7 Project and add references to the DLL’s by right clicking on the References folder and clicking “Add references”.   After adding the references, we can get started. I needed a ProgressOverlay animation or “Loading Screen” while my RSS feed is downloading. Basically, you just need to add the following namespace to whatever page you want the control on: xmlns:Controls="clr-namespace:Coding4Fun.Phone.Controls;assembly=Coding4Fun.Phone.Controls" And then the code inside your Grid or wherever you want the Loading screen placed. <Controls:ProgressOverlay Name="progressOverlay" > <Controls:ProgressOverlay.Content> <TextBlock>Loading</TextBlock> </Controls:ProgressOverlay.Content> </Controls:ProgressOverlay> Bam, you now have a great looking loading screen. Of course inside the ProgressOverlay, you may want to add a Visibility property to turn it off after your data loads if you are using MVVM or similar pattern.   Next up, I needed a nice clean “About Box” that looks good but is also functional. Meaning, if they click on my twitter name, web or email to launch the appropriate task. Again, this is only a few lines of code: var p = new AboutPrompt(); p.VersionNumber = "2.0"; p.Show("Michael Crump", "@mbcrump", "[email protected]", @"http://michaelcrump.net"); A nice clean “About” box with just a few lines of code! I’m all for code that I don’t have to write. It also comes with a pretty sweet InputPrompt for grabbing info from a user: The code for this is also very simple: InputPrompt input = new InputPrompt(); input.Completed += (s, e) => { MessageBox.Show(e.Result.ToString()); }; input.Title = "Input Box"; input.Message = "What does a \"Developer Large\" T-Shirt Mean? "; input.Show(); I also enjoyed the PhoneHelper that allows you to get data out of the WMAppManifest File very easy. So for example if I wanted the Version info from the WMAppManifest file. I could write one line and get it. PhoneHelper.GetAppAttribute("Version") Of course you would want to make sure you add the following using statement: using Coding4Fun.Phone.Controls.Data; You can’t have all these cool controls without a great set of Converters. The included BooleanToVisibility converter will convert a Boolean to and from a Visibility value. This is excellent when using something like a CheckBox to display a TextBox when its checked. See the example below: The code is below: <phone:PhoneApplicationPage.Resources> <Converters:BooleanToVisibilityConverter x:Key="BooleanToVisibilityConverter"/> </phone:PhoneApplicationPage.Resources> <CheckBox x:Name="checkBox"/> <TextBlock Text="Display Text" Visibility="{Binding ElementName=checkBox, Path=IsChecked, Converter={StaticResource BooleanToVisibilityConverter} }"/> That’s not all the goodies included. They also provide a RoundedButton, TimePicker and several other converters. The documentation is great and I would recommend you give them a shot if you need any of this functionality. Btw, thank Brian Peek for his awesome work on Coding4Fun!  Subscribe to my feed

• How do you install a USB CD Rom drive?

  - by Matt Allen

  Hello, I recently purchased a USB CD ROM drive, but I don't know how to get it to work with my computer which runs Ubuntu 10.04. http://www.amazon.com/gp/product/B00303H908/ref=oss_product When I issue the lsusb command, it shows up as: Bus 002 Device 016: ID 05e3:0701 Genesys Logic, Inc. USB 2.0 IDE Adapter The computer doesn't recognize it automatically. How can I get this drive to show up as an actual drive on my computer? If this particular drive can't handle Linux, can you recommended one which can and provide a link to it so I can purchase it? Thanks!

• Anatomy of a serialization killer

  - by Brian Donahue

  As I had mentioned last month, I have been working on a project to create an easy-to-use managed debugger. It's still an internal tool that we use at Red Gate as part of product support to analyze application errors on customer's computers, and as such, should be easy to use and not require installation. Since the project has got rather large and important, I had decided to use SmartAssembly to protect all of my hard work. This was trivial for the most part, but the loading and saving of results was broken by SA after using the obfuscation, rendering the loading and saving of XML results basically useless, although the merging and error reporting was an absolute godsend and definitely worth the price of admission. (Well, I get my Red Gate licenses for free, but you know what I mean!)My initial reaction was to simply exclude the serializable results class and all of its' members from obfuscation, and that was just dandy, but a few weeks on I decided to look into exactly why serialization had broken and change the code to work with SA so I could write any new code to be compatible with SmartAssembly and save me some additional testing and changes to the SA project.In simple terms, SA does all that it can to prevent serialization problems, for instance, it will not obfuscate public members of a DLL and it will exclude any types with the Serializable attribute from obfuscation. This prevents public members and properties from being made private and having the name changed. If the serialization is done inside the executable, however, public members have the access changed to private and are renamed. That was my first problem, because my types were in the executable assembly and implemented ISerializable, but did not have the Serializable attribute set on them!public class RedFlagResults : ISerializable        {        }The second problem caused by the pruning feature. Although RedFlagResults had public members, they were not truly properties, and used the GetObjectData() method of ISerializable to serialize the members. For that reason, SA could not exclude these members from pruning and further broke the serialization. public class RedFlagResults : ISerializable        {                public List<RedFlag.Exception> Exceptions;                 #region ISerializable Members                 public void GetObjectData(SerializationInfo info, StreamingContext context)                {                                info.AddValue("Exceptions", Exceptions);                }                 #endregionSo to fix this, it was necessary to make Exceptions a proper property by implementing get and set on it. Also, I added the Serializable attribute so that I don't have to exclude the class from obfuscation in the SA project any more. The DoNotPrune attribute means I do not need to exclude the class from pruning.[Serializable, SmartAssembly.Attributes.DoNotPrune]        public class RedFlagResults        {                public List<RedFlag.Exception> Exceptions {get;set;}        }Similarly, the Exception class gets the Serializable and DoNotPrune attributes applied so all of its' properties are excluded from obfuscation.Now my project has some protection from prying eyes by scrambling up the code so it's harder to reverse-engineer, without breaking anything. SmartAssembly has also provided the benefit of merging so that the end-user doesn't need to extract all of the DLL files needed by RedFlag into a directory, and can be run directly from the .zip archive. When an error occurs (hey, I'm only human!), an exception report can be sent to me so I can see what went wrong without having to, er, debug the debugger.

• How to detect and configure an output with xrandr?

  - by ysap

  I have a DELL U2410 monitor connected to a Compaq 100B desktop equipped with an integrated AMD/ATI graphics card (AMD E-350). The installed O/S is Ubuntu 10.04 LTS. The computer is connected to the monitor via the DVI connection. The problem is that I cannot set the desktop resolution to the native 1920x1200. The maximum allowed resolution is 1600x1200. Doing some research I found about the xrandr utility. Unfortunately, when trying to use it I cannot configure it to the required resolution. First, it does not report the output name (which supposed to be DVI-0), saying default instead. Without it I cannot use the --fb option. The EDID utility seems to identify the monitor well. Here's the output from get-edid: # EDID version 1 revision 3 Section "Monitor" # Block type: 2:0 3:ff # Block type: 2:0 3:fc Identifier "DELL U2410" VendorName "DEL" ModelName "DELL U2410" # Block type: 2:0 3:ff # Block type: 2:0 3:fc # Block type: 2:0 3:fd HorizSync 30-81 VertRefresh 56-76 # Max dot clock (video bandwidth) 170 MHz # DPMS capabilities: Active off:yes Suspend:yes Standby:yes Mode "1920x1200" # vfreq 59.950Hz, hfreq 74.038kHz DotClock 154.000000 HTimings 1920 1968 2000 2080 VTimings 1200 1203 1209 1235 Flags "-HSync" "+VSync" EndMode # Block type: 2:0 3:ff # Block type: 2:0 3:fc # Block type: 2:0 3:fd EndSection but the xrandr -q command returns: Screen 0: minimum 640 x 400, current 1600 x 1200, maximum 1600 x 1200 default connected 1600x1200+0+0 0mm x 0mm 1600x1200 0.0* 1280x1024 0.0 1152x864 0.0 1024x768 0.0 800x600 0.0 640x480 0.0 720x400 0.0 When I try to set the resolution, I get: $ xrandr --fb 1920x1200 xrandr: screen cannot be larger than 1600x1200 (desired size 1920x1200) $ xrandr --output DVI-0 --auto warning: output DVI-0 not found; ignoring How can I set the screen resolution to 1920x1200? Why doesn't xrandr identify the DVI-0 output? Note that the same computer running Ubuntu version higher than 10.04 detects the correct resolution with no problems. On this machine I cannot upgrade due to some legacy hardware compatibility problems. Also, I don't see any optional screen drivers available in the Hardware Drivers dialog. ---- UPDATE: following the answer to this question, I got some advance. Now the required mode is listed in the xrandr -q list, but I can't switch to that mode. Using the Monitors applet (which now shows the new mode), I get the response that: The selected configuration for displays could not be applied. Could not set the configuration to CRTC 262.

• Autoscaling in a modern world&hellip;. last chapter

  - by Steve Loethen

  As we all know as coders, things like logging are never important.  Our code will work right the first time.  So, you can understand my surprise when the first time I deployed the autoscaling worker role to the actual Azure fabric, it did not scale.  I mean, it worked on my machine.  How dare the datacenter argue with that.  So, how did I track down the problem?  (turns out, it was not so much code as lack of the right certificate)  When I ran it local in the developer fabric, I was able to see a wealth of information.  Lots of periodic status info every time the autoscalar came around to check on my rules and decide to act or not.  But that information was not making it to Azure storage.  The diagnostics were not being transferred to where I could easily see and use them to track down why things were not being cooperative.  After a bit of digging, I discover the problem.  You need to add a bit of extra configuration code to get the correct information stored for you.  I added the following to my app.config: Code Snippet <system.diagnostics>     <sources>         <source name="Autoscaling General"switchName="SourceSwitch"           switchType="System.Diagnostics.SourceSwitch" >         <listeners>           <add name="AzureDiag" />             <remove name="Default"/>         </listeners>       </source>         <source name="Autoscaling Updates"switchName="SourceSwitch"           switchType="System.Diagnostics.SourceSwitch" >         <listeners>           <add name="AzureDiag" />             <remove name="Default"/>         </listeners>       </source>     </sources>     <switches>       <add name="SourceSwitch"           value="Verbose, Information, Warning, Error, Critical" />     </switches>     <sharedListeners>       <add type="Microsoft.WindowsAzure.Diagnostics.DiagnosticMonitorTraceListener,Microsoft.WindowsAzure.Diagnostics, Version=1.0.0.0, Culture=neutral,PublicKeyToken=31bf3856ad364e35" name="AzureDiag"/>     </sharedListeners>     <trace>       <listeners>         <add             type="Microsoft.WindowsAzure.Diagnostics.DiagnosticMonitorTraceListener,Microsoft.WindowsAzure.Diagnostics, Version=1.0.0.0, Culture=neutral,PublicKeyToken=31bf3856ad364e35" name="AzureDiagnostics">           <filter type="" />         </add>       </listeners>     </trace>   </system.diagnostics> Suddenly all the rich tracing info I needed was filling up my storage account.  After a few cycles of trying to attempting to scale, I identified the cert problem, uploaded a correct certificate, and away it went.  I hope this was helpful.

• jtreg update, March 2012

  - by jjg

  There is a new update for jtreg 4.1, b04, available. The primary changes have been to support faster and more reliable test runs, especially for tests in the jdk/ repository. [ For users inside Oracle, there is preliminary direct support for gathering code coverage data using jcov while running tests, and for generating a coverage report when all the tests have been run. ] -- jtreg can be downloaded from the OpenJDK jtreg page: http://openjdk.java.net/jtreg/. Scratch directories On platforms like Windows, if a test leaves a file open when the test is over, that can cause a problem for downstream tests, because the scratch directory cannot be emptied beforehand. This is addressed in agentvm mode by discarding any agents using that scratch directory and starting new agents using a new empty scratch directory. Successive directives use suffices _1, _2, etc. If you see such directories appearing in the work directory, that is an indication that files were left open in the preceding directory in the series. Locking support Some tests use shared system resources such as fixed port numbers. This causes a problem when running tests concurrently. So, you can now mark a directory such that all the tests within all such directories will be run sequentially, even if you use -concurrency:N on the command line to run the rest of the tests in parallel. This is seen as a short term solution: it is recommended that tests not use shared system resources whenever possible. If you are running multiple instances of jtreg on the same machine at the same time, you can use a new option -lock:file to specify a file to be used for file locking; otherwise, the locking will just be within the JVM used to run jtreg. "autovm mode" By default, if no options to the contrary are given on the command line, tests will be run in othervm mode. Now, a test suite can be marked so that the default execution mode is "agentvm" mode. In conjunction with this, you can now mark a directory such that all the tests within that directory will be run in "othervm" mode. Conceptually, this is equivalent to putting /othervm on every appropriate action on every test in that directory and any subdirectories. This is seen as a short term solution: it is recommended tests be adapted to use agentvm mode, or use "@run main/othervm" explicitly. Info in test result files The user name and jtreg version info are now stored in the properties near the beginning of the .jtr file. Build The makefiles used to build and test jtreg have been reorganized and simplified. jtreg is now using JT Harness version 4.4. Other jtreg provides access to GNOME_DESKTOP_SESSION_ID when set. jtreg ensures that shell tests are given an absolute path for the JDK under test. jtreg now honors the "first sentence rule" for the description given by @summary. jtreg saves the default locale before executing a test in samevm or agentvm mode, and restores it afterwards. Bug fixes jtreg tried to execute a test even if the compilation failed in agentvm mode because of a JVM crash. jtreg did not correctly handle the -compilejdk option. Acknowledgements Thanks to Alan, Amy, Andrey, Brad, Christine, Dima, Max, Mike, Sherman, Steve and others for their help, suggestions, bug reports and for testing this latest version.

• how do i fix this: the networking and wireless are enabled. but list of networks under wireless networks not available

  - by Ayesha Ahmad

  i started working with ubuntu 11.10 last year. i upgraded to 12.04 a week back. since then i have had all sorts of problems with network connection. first had to install the new driver. the hardware switch somehow got disabled then the above problem arrived. even tho the options are all enabled, the OS is not able to detect scan available network connections. also i have to bring to notice that once in a while it does get connected, can not explain how it happens. I want to fix this problem once and for all. please help. ifconfig: eth0 Link encap:Ethernet HWaddr f0:4d:a2:51:b3:c8 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:44 eth1 Link encap:Ethernet HWaddr 1c:65:9d:67:d5:e1 inet6 addr: fe80::1e65:9dff:fe67:d5e1/64 Scope:Link UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:170 TX packets:0 errors:27 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:17 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:344 errors:0 dropped:0 overruns:0 frame:0 TX packets:344 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:20336 (20.3 KB) TX bytes:20336 (20.3 KB) lshw -c network *-network description: Wireless interface product: BCM4313 802.11b/g/n Wireless LAN Controller vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:03:00.0 logical name: eth1 version: 01 serial: 1c:65:9d:67:d5:e1 width: 64 bits clock: 33MHz capabilities: bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=wl0 driverversion=5.100.82.38 latency=0 multicast=yes wireless=IEEE 802.11 resources: irq:17 memory:f0500000-f0503fff *-network description: Ethernet interface product: AR8152 v1.1 Fast Ethernet vendor: Atheros Communications Inc. physical id: 0 bus info: pci@0000:04:00.0 logical name: eth0 version: c1 serial: f0:4d:a2:51:b3:c8 capacity: 100Mbit/s width: 64 bits clock: 33MHz capabilities: bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=atl1c driverversion=1.0.1.0-NAPI firmware=N/A latency=0 multicast=yes port=twisted pair resources: irq:44 memory:f0400000-f043ffff ioport:2000(size=128) iwconfig lo no wireless extensions. eth1 IEEE 802.11 Access Point: Not-Associated Link Quality:5 Signal level:0 Noise level:196 Rx invalid nwid:0 invalid crypt:0 invalid misc:0 eth0 no wireless extensions. lspci 00:00.0 Host bridge: Intel Corporation Core Processor DRAM Controller (rev 18) 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 18) 00:16.0 Communication controller: Intel Corporation 5 Series/3400 Series Chipset HECI Controller (rev 06) 00:1a.0 USB controller: Intel Corporation 5 Series/3400 Series Chipset USB2 Enhanced Host Controller (rev 06) 00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 06) 00:1c.0 PCI bridge: Intel Corporation 5 Series/3400 Series Chipset PCI Express Root Port 1 (rev 06) 00:1c.1 PCI bridge: Intel Corporation 5 Series/3400 Series Chipset PCI Express Root Port 2 (rev 06) 00:1c.5 PCI bridge: Intel Corporation 5 Series/3400 Series Chipset PCI Express Root Port 6 (rev 06) 00:1d.0 USB controller: Intel Corporation 5 Series/3400 Series Chipset USB2 Enhanced Host Controller (rev 06) 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev a6) 00:1f.0 ISA bridge: Intel Corporation Mobile 5 Series Chipset LPC Interface Controller (rev 06) 00:1f.2 SATA controller: Intel Corporation 5 Series/3400 Series Chipset 6 port SATA AHCI Controller (rev 06) 00:1f.3 SMBus: Intel Corporation 5 Series/3400 Series Chipset SMBus Controller (rev 06) 00:1f.6 Signal processing controller: Intel Corporation 5 Series/3400 Series Chipset Thermal Subsystem (rev 06) 03:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01) 04:00.0 Ethernet controller: Atheros Communications Inc.
