    How can you compile the code using javac in a terminal by using google-collections in CLASSPATH? Example of code trying to compile using javac in a terminal (works in Eclipse) import com.google.common.collect.BiMap; import com.google.common.collect.HashBiMap; public class Locate { ...

  • emails not sending from CentOS 5.6 VM on Win7 via PHP code

    - by crmpicco
    I am experiencing an issue where my CentOS 5.6 (Final) VM running on Windows 7 has stopped sending emails from my PHP code. I'm confident this isn't a coding issue as I have the exact same code running in my office and emails send correctly from there, hence why I believe this to be a networking/configuration issue. In my /etc/hosts/ file on my VM I have the following: 127.0.0.1 localhost.localdomain localhost 192.168.0.9 crmpicco.co.uk m.crmpicco.co.uk dev53.localdomain When I run setup on my VM the DNS configuration is set to dev53.localdomain and my Primary DNS is 192.168.0.1. In My /var/log/maillog files I see a lot of this sort of thing: Nov 19 14:36:58 dev53 sendmail[21696]: qAJEawI7021696: from=<[email protected]>, size=12858, class=0, nrcpts=1, msgid=<1353335817.9103820024efb30b451d006dc4ab3370@PHPMAILSERVER>, proto=ESMTP, daemon=MTA, relay=localhost.localdomain [127.0.0.1] Nov 19 14:36:58 dev53 sendmail[21693]: qAJEawvd021693: [email protected], [email protected] (48/48), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=42681, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (qAJEawI7021696 Message accepted for delivery) Nov 19 14:36:59 dev53 sendmail[21698]: qAJEawI7021696: to=<[email protected]>, delay=00:00:01, xdelay=00:00:01, mailer=esmtp, pri=132858, relay=mailserver.fletcher.co.uk.

  • Failing Windows Updates with Error Code 800719e4

    - by Kev
    On a number of Vista machines I have now come across the same error - when installing updates everything works fine, until it after it reboots and the rolls back during step 3. On all occasions (where a simple retry hasn't worked) the error code has been 800719e4. On my own laptop I have so far tried the following:- Installed the updates one by one manually - I started on the smallest and one by one have worked towards the largest one which has left me with "Security Update for Windows (KB2286198)" that refuses to install. Renamed all the files in "C:\Windows\Logs\CBS" to "xxx.old" where xxx was the original name with windows update turned off - no change Renamed all the folders in "C:\Windows\SoftwareDistribution" in the same manner - no change Attempted to install it manually "Windows6.0-KB2286198-x86.msu" - no change Tried to un-install IE8 - doesn't work, rolls back at the end (Installing the IE9 Beta when it launched was what alerted me to the issue on this laptop) Ran a "Fix It" thing from the Microsoft Website - no help (Can't find the link now). Tried to recover from the disk - but alas my laptop only has a recovery partition (and was unservice packed original). Ran with nothing running on startup, and only MS services - again no change. Google is being useless with a load of posts trying to get me to call a telephone number with letters in (presumably an American number) The error code appears to mean error log full but no one has any idea which log! The WinUpdate log does indicate the following is the error point though :- 2010-10-23 13:54:48:230 1240 738 Handler WARNING: Got extended error: "POQ Operation SetKeyValue OperationData \Registry\machine\Schema\wcm://Microsoft-Windows-shell32?version=6.0.6002.18287&language=neutral&processorArchitecture=x86&publicKeyToken=31bf3856ad364e35&versionScope=nonSxS&scope=allUsers\metadata\elements\HKEY_CLASSES_ROOT_lnkfile_shellex_DropHandler_defaultValue, @default, , ewAwADAAMAAyADEANAAwADEALQAwADAAMAAwAC0AMAAwADAAMAAtAEMAMAAwADAALQAwADAAMAAwADAAMAAwADAAMAAwADQANgB9AAAA" Has anyone any idea how to fix this once and for all - reinstalling laptop after laptop from scratch is mildly annoying at work where Office and Firefox are the only extras, but even more annoying at home - I don't fancy going through the palaver of reinstalling everything yet again.

  • Internal Code Signing: Key Distribution, or Certificate Server?

    - by Myrddin Emrys
    I should first note that we have nobody in IT with significant familiarity with self-signed certification. We have a moderately sprawling network (one forest, many locations), and we are now rolling out internal code signing; until now users have run untrusted code, or we even disabled(!) the warnings. Intranet applications, scripts, and sites will now be signed with self certification. I am aware of two obvious ways we can deploy this: Distributing the keys directly via a group policy, and setting up a cert server. Can someone explain the trade-offs between these two methods? How many certs before the group policy method is unwieldy? Are they large enough that remote users will have issues? Does the group policy method distribute duplicates on every login? Is there a better method I am not aware of? I can find a lot of documentation on certifications and various ways to create them, but I have not been able to find something that summarizes the difference between the distribution methods and what criteria make one or the other superior.

  • Howto get exit code of a script started in screen session

    - by Bettina
    Hi folks, I am currently creating a backup script which uses screen to start a backup job with rsync inside a screen session. The backup jobs are started as follows. screen -dmS backup /usr/bin/rsync ... As soon as the rsync job is finished, the screen session is terminated automatically. To make sure, that the backup was successful, I would like to check the exit code of the rsync job but unfortunately I really don't know how to get the exit code after the screen was terminated. Does someone have a good idea how to automatically check, if the rsync job was successful or not? Would be great if someone does. I already thought about using a temp file but like this: screen -dmS myScreen "rsync -av ... ; echo $? /tmp/myExitCode" but this unfortunately does not work. Then I thought about using stderr like in the example below: screen -dmS myScreen "rsync -av ... 2 /tmp/rsync-sterr None of my ideas worked out so far, since stderr is not written when I use the command above. :-( ? Would be great if someone has a good idea or even a solution. Cheers, Bettina

  • Mod_pagespeed, Varnish and Apache cache issues after new code pushes

    - by WerkkreW
    I have a rather strange issue. In my environment we are running a load balanced cluster of 8 apache servers with a master-master MySQL backend. In front of apache we have Varnish in the cache layer. We have been running Apache mod_pagespeed for several weeks now and for the most part it has been working great. The issue arises when we do fresh code updates from Git, and and/all of the JS/CSS assets change. Basically the problem appears to be two fold. One, after the code push we generally take the opportunity to flush varnish, restart apache, and restart varnish. In doing this all of the mod_pagespeed combinied/minified files are cleared out ensuring that all of the new JS/CSS assets are fresh. The problem is, upon doing this the file names that mod_pagespeed creates change, but the old files (appear) to be still cached for many people client side leading to very unexpected results. However, if we do not restart apache, the changes to the files may or may not appear client side due to the cached minified assets. The simple solution is to disable mod_pagespeed, however I would rather not do that as it has made a fairly large impact in performance. I feel as if there must be a better way to deal with the inconsistencies in cache between the client and server to prevent having people to go to great lengths or perform a large number of page refreshes to see a working page. I can provide configuration snippets if anyone needs them. If you would like to inspect the site, source, headers, or anything try the following addresses: http://wellplayed.org http://wellplayed.org/tv Thanks in advance!

  • Share code between projects in tfs 2010

    - by Jimmy Engtröm
    Hi What is the best way to handle code sharing in TFS 2010? We have a couple of Visual studio projects that other Visual Studio projects use. ex: Shared Project Project 1 Solution -Shared Project -Project 1 Project Project 2 Solution -Shared Project -Project 2 Project Also we have Third party code for example: Third Party -Telerik --2009.1.402.35 --2009.02.0701.35 When I open my "Project 1" solution i want my shared code project to be included in that solution. (thats the way we work today). We basically have one TFS Project that contains all the code. Now we want to use it the "right" (?) way, We would like to have Project 1 and 2 in separate TFS solutions. If I for example makes sure we have all our project in the same structure on disk and just add the shared project to my Project 1 solution (even if the projects reside in two different TFS Projects) would that work with builds? How have you solved the problem, I guess we are not the only ones having shared code between projects? Cheers /Jimmy

  • Visual C# GUI Designer - Recommended way of removing generated event handler-code & basic tutorial

    - by cusack
    Hi, I'm new to the Visual C# designer so these are general and pretty basic question on how to work with the designer. When we for instance add a label to a form and then double-click on it in the Visual C# designer (I'm using Microsoft Visual C# 2008 Express Edition), the following things happen: The designer generates code within Form1.Designer.cs (assume default names for simplicity) to add the label, then with the double-click it will add the event handler label1_Click to the label within Form1.Designer.cs, using the following code this.label1.Click += new System.EventHandler(this.label1_Click); and it adds the event handler method to Form1.cs private void label1_Click(object sender, EventArgs e) { } If I now remove the label only the code within Form1.Designer.cs will be removed but the label1_Click method will stay within Form1.cs even if it isn't used by anything else. But if I'm using reset within Properties-Events for the Click-event from within the designer even the label1_Click method in Form1.cs will be removed. 1.) Isn't that a little inconsistent behavior? 2.) What is the recommended way of removing such generated event handler-code? 3.) What is the best "mental approach"/best practice for using the designer? I would approach it by mental separation in the way that Form1.cs is 100% my responsibility and that on the other hand I'm not touching the code in Form1.Designer.cs at all. Does that make sense or not? Since sometimes the designer removes sth. from Form1.cs I'm not sure about this. 4.) Can you recommend a simple designer tutorial that assumes no Visual C# designer knowledge but expects/doesn't explain C#. The following one is an example of what I would not want it explains what a c#-comment is and I'd prefer text over video as well: http://msdn.microsoft.com/en-us/beginner/bb964631.aspx

  • Figuring Out Memory Leaks without Clang

    - by RoLYroLLs
    I'm trying to see if I can find some leaks myself in Apple's TopSongs app. Can someone help me out in at least one and how to identify what is in the Leaks reports and how I can get an idea on finding them? ie: I got one like this: # Category Event Type Timestamp Address Size Responsible Library Responsible Caller 0 GeneralBlock-448 Malloc 00:02.185 0x3f41220 448 libxml2.2.dylib xmlNewParserCtxt From what I can tell, the method xmlNewParserCtxt is the problem, and it's not releasing an object, hence Malloc. The responsible library tells me it's the libxml2.2.dylib library with the problem, which I can't edit. Am I heading in the right direction? If so, half the leaks are in that library and well, i can't edit that.

  • Using CHDataStructures.framework on iPhone

    - by nununo
    Hi, I'm new to iPhone programming and I'm trying to use CHDataStructures in my project. But I'm running into some issues: When I directly try to build it right after download I get the error "Foundation/Foundation.h" no such file or directory. The Active SDK is "Use Base SDK" and the active architecture is x86_64. I believe I should set the Active SDK to the iPhone SDK but it isn't listed there; At some point (I don't remember how) I managed to tweak it and I got the iPhone SDK (simulator) in the active SDK but when I tried to build it I got the following error: "target specifies product type 'com.apple.product-type.framework', but there's no such product type for the 'iphonesimulator' platform"; And now I'm stuck. What am I doing wrong? Thanks in advance, Nuno

  • which metric(s) show the difference between object-oriented and procedural code

    - by twieger
    Which metric(s) could help to indicate that i have procedural code instead of object-oriented code? I would like to have a set of simple metrics, which indicate with a high probability, that the analyzed code contains procedural transaction scripts and an anemic domain model instead of following sound object-oriented design principles. Would be happy about any set of useful metrics and tools for measuring. Thanks, Thomas!

    I have a program that allows a user to type java code into a rich text box and then compile it using the java compiler. Whenever I try to compile the code that I have written I get an error that says that I have an illegal character at the beginning of my code that is not there. This is the error the compiler is giving me: C:\Users\Travis Michael>"\Program Files\Java\jdk1.6.0_17\bin\javac" Test.java Test.java:1: illegal character: \187 n++public class Test ^ Test.java:1: illegal character: \191 n++public class Test ^ 2 errors

  • Alternative for my preg_replace code

    - by Ben Sinclair
    Here is my code... basically it finds any page-NUMBER- within a variable and then replaces it with a page url from an array $content_text = preg_replace("/page-(\d+)-/sie", '$pageurl[$1]', $content_text); It works a treat until the NUMBER it finds isn't in the array and it returns an error... Is there another efficient way I could do this instead? I liked my code above because it was simple but I may have to use more complex code...

  • Tiff Analyzer

    - by Kevin
    I am writing a program to convert some data, mainly a bunch of Tiff images. Some of the Tiffs seems to have a minor problem with them. They show up fine in some viewers (Irfanview, client's old system) but not in others (Client's new system, Window's picture and fax viewer). I have manually looked at the binary data and all the tags seem ok. Can anyone recommend an app that can analyze it and tell me what, if anything, is wrong with it? Also, for clarity sake, I'm only converting the data about the images which is stored seperately in a database and copying the images, I'm not editting the images myself, so I'm pretty sure I'm not messing them up.

  • CLang error (objective C): value stored during initialization is never read

    - by Scott Pendleton
    Foo *oFoo = [[[Foo alloc] init] autorelease]; This is how I was taught to program in Objective C, yet the CLang error checker complains that the initial value was never read. But oFoo is an object with properties. oFoo itself has no single value. The property values are what matter. oFoo.PropertyA = 1; oFoo.PropertyB = @"Hello, World." Should I just ignore this? Is this worth fixing? What is the fix, seeing that "initial value" is meaningless in my context?

    Hi, I have an WPF Microsoft Surface Applikation and I'm using MVVM-Pattern. I have some buttons that are created in code behind. And I would like to bind commands to them but I only know how that works in the XAML like this: <Custom:SurfaceButton Command="{Binding SaveReservationCommandBinding, Mode=OneWay}"/> But I cannot do it like this because my buttons do not exist in the XAML, only in the code behind. So how would a command binding like that works in code behind?

  • Refactoring method with many conditional return statements

    Hi, I have a method for validation that has many conditional statements. Basically it goes If Check1 = false return false If Check2 = false return false etc FxCop complains that the cyclomatic complexity is too high. I know that it is not best practice to have return statements in the middle of functions, but at the same time the only alternative I see is an ugly list of If-else statements. What is the best way to approach this? Thanks in advance.

  • Using Taylor Series to Avoid Loss of Precision

    - by Zachary
    I'm trying to use Taylor series to develop a numerically sound algorithm for solving a function. I've been at it for quite a while, but haven't had any luck yet. I'm not sure what I'm doing wrong. The function is f(x)=1 + x - sin(x)/ln(1+x) x~0 Also: why does loss of precision even occur in this function? when x is close to zero, sin(x)/ln(1+x) isn't even close to being the same number as x. I don't see where significance is even being lost. In order to solve this, I believe that I will need to use the Taylor expansions for sin(x) and ln(1+x), which are x - x^3/3! + x^5/5! - x^7/7! + ... and x - x^2/2 + x^3/3 - x^4/4 + ... respectfully. I have attempted to use like denominators to combine the x and sin(x)/ln(1+x) components, and even to combine all three, but nothing seems to work out correctly in the end. Any help is appreciated.

  • Android NDK - does it support straight ARM code or just Thumb

    - by Russell Kay
    All, I have been asked to evaluate the Android platform for our product and I am looking at various options, I am only just scratching the surface just now and the one thing that is bothering me is that I cannot see how to compile code as straight ARM code (no Thumb), I know that Thumb runs slower and we will need the performance in key sections of our code. I think it should just be setting the -march flag in the LOCAL_CFLAGS of the Android.mk file, but I cannot get that to work... Can anyone help. Russell

  • Can someone please explain this lazy evaluation code?

    - by Tejs
    So, this question was just asked on SO: http://stackoverflow.com/questions/2740001/how-to-handle-an-infinite-ienumerable My sample code: public static void Main(string[] args) { foreach (var item in Numbers().Take(10)) Console.WriteLine(item); Console.ReadKey(); } public static IEnumerable<int> Numbers() { int x = 0; while (true) yield return x++; } Can someone please explain why this is lazy evaluated? I've looked up this code in Reflector, and I'm more confused than when I began. Reflector outputs: public static IEnumerable<int> Numbers() { return new <Numbers>d__0(-2); } For the numbers method, and looks to have generated a new type for that expression: [DebuggerHidden] public <Numbers>d__0(int <>1__state) { this.<>1__state = <>1__state; this.<>l__initialThreadId = Thread.CurrentThread.ManagedThreadId; } This makes no sense to me. I would have assumed it was an infinite loop until I put that code together and executed it myself.

  • RegisterClientScriptBlock code not executing.

    - by ProfK
    I'm using the following code in an attempt to show a dialog with a list of errors on the client: if (rollout.ImportErrors.Count > 0) { ClientScript.RegisterClientScriptBlock(GetType(), "showErrors", "showErrors();", true); } The error count is non-zero and the following script block is emitted, but the script isn't executing. <script type="text/javascript"> //<![CDATA[ $("#error-report").dialog("open")//]]> </script> If I call the function directly from a Firebug console window, the dialog shows properly, so I know the dialog and my code are working. What am I doing wrong? BTW, this code is in a content page, using a content placeholder that 'injects' code into the element of the rendered page.

  • What is the correct way to synchronize a shared, static object in Java?

    - by johnrock
    This is a question concerning what is the proper way to synchronize a shared object in java. One caveat is that the object that I want to share must be accessed from static methods. My question is, If I synchronize on a static field, does that lock the class the field belongs to similar to the way a synchronized static method would? Or, will this only lock the field itself? In my specific example I am asking: Will calling PayloadService.getPayload() or PayloadService.setPayload() lock PayloadService.payload? Or will it lock the entire PayloadService class? public class PayloadService extends Service { private static PayloadDTO payload = new PayloadDTO(); public static void setPayload(PayloadDTO payload){ synchronized(PayloadService.payload){ PayloadService.payload = payload; } } public static PayloadDTO getPayload() { synchronized(PayloadService.payload){ return PayloadService.payload ; } } ... Is this a correct/acceptable approach ? In my example the PayloadService is a separate thread, updating the payload object at regular intervals - other threads need to call PayloadService.getPayload() at random intervals to get the latest data and I need to make sure that they don't lock the PayloadService from carrying out its timer task
