• Update a tableView with a plist took from another table

  - by Pheel

  Background: I have a tab bar application, which has a tableView as the "heart" of the app. It loads data from a plist and, through a button that checks if there are any updates on the remote plist file, updates the local plist with the remote contents. Then, i have another tableView, that should display only those plist items that have a bool value set to YES. Now i want to add a button to the second table that reloads the plist took from the first table. Expected: When i update the local plist from the first table and when i press the button on the second table, the 2nd table is supposed to update and show the cells with that bool value set to YES. (Note: I set YES as default to some items on plist). What happens: The first table updates its content from remote. The second table shows the old items with the value set to YES. When i press the button to refresh data, it reads the plist fine (by logging it, it has the same contents of the first table -only those set to YES-),but it doesn't update data even if i have [self.tableView reloadData];. When i close the app and open it again, the second table is filled with the right items. :\ Code i'm using: //Reading Plist { NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES); NSString *plistPath = [[documentPaths lastObject] stringByAppendingPathComponent:@"myPlist.plist"]; NSFileManager *fMgr = [NSFileManager defaultManager]; if (![fMgr fileExistsAtPath:plistPath]) { plistPath = [[NSBundle mainBundle] pathForResource:@"myPlist" ofType:@"plist"]; } NSMutableArray *returnArr = [NSMutableArray arrayWithContentsOfFile:plistPath]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"isFav == YES"]; for (NSDictionary *sect in returnArr) { NSArray *arr = [sect objectForKey:@"Rows"]; [sect setValue:[arr filteredArrayUsingPredicate:predicate] forKey:@"Rows"]; } [self.tableView reloadData]; } //Refresh data button - (void) refreshTable:(id)sender { NSLog(@"plist read"); [self readPlist]; NSLog(@"refreshed plist:%@",[self readPlist]); [self.tableView reloadData]; } Does anyone know why the table is not updating?

• Adding exclusive filter for <static initializer> in findbugs

  - by MilanAleksic

  Hi all, I want my findbugs report not show the following error: DM_NUMBER_CTOR: Method invokes inefficient Number constructor; use static valueOf instead The problem is that this happens in groovy-generated code files, so I can't control the source code - that is why I want to exclude it and add it to my exclude filter. I do not want to add explicitly class (since I make API that many tools will use, I want my filter to be generic). I would not like to completely remove this bug from the report by type, I would really like to only exclude this bug from appearing if it happenned in "static initializer" methods. Any idea? I tried the filter below but no luck, maybe somebody has better idea? <Match> <Method name="~.*static initializer.*" /> <Bug pattern="DM_NUMBER_CTOR" /> </Match> Here is the "stacktrace" of FindBugs in that case: In class net.milanaleksic.cuc.tools.sound.SoundPlayerTool In method net.milanaleksic.cuc.tools.sound.SoundPlayerTool.() Called method new Long(long) Should call Long.valueOf(long) instead In SoundPlayerTool.groovy

• How can I protect my .NET assemblies from decompilation?

  - by Holli

  One if the first things I learned when I started with C# was the most important one. You can decompile any .NET assembly with Reflector or other tools. Many developers are not aware of this fact and most of them are shocked when I show them their source code. Protection against decompilation is still a difficult task. I am still looking for a fast, easy and secure way to do it. I don't want to obfuscate my code so my method names will be a,b,c or so. Reflector or other tools should be unable to recognize my application as .NET assembly at all. I know about some tools already but they are very expensive. Is there any other way to protect my applications? EDIT: The reason for my question is not to prevent piracy. I only want to stop competitors from reading my code. I know they will and they already did. They even told me so. Maybe I am a bit paranoid but business rivals reading my code doesn't make me feel good.

• Synchronizing screencasting (ffmpeg) and capturing from the webcam (OpenCV)

  - by lyuba

  As from my previous questions, I am trying to build a simple eye tracker. Decided to start from a Linux version (run Ubuntu). To complete this task one should organize screencasting and webcam capturing in such way that frames from both streams exactly match each other and there is the same number of frames in each of them totally. Screencasting fsp fully depends on the camera's fsp, so each time we get the image from the webcam we can potentially grab a screen frame and stay happy. However, all the tools for the fast screencasting, like ffmpeg, for example, return the .avi file as the result and require the fsp already known to be started. From the other side, tools like Java+Robot or ImageMagick seem to require around 20ms to return the .jpg screenshot, which is pretty slow for the task. But they may be requested right after each time the webcam frame is grabbed and provide the needed synchronization. So the sub-questions are: 1. Does the USD camera's frame rate vary during a single session? 2. Are there any tools which provide fast screencasting frame by frame? 3. Is there any way to make ffmpeg push a new frame to the .avi file only when program initiates this request? For my task I may either use C++ or Java. I am, actually, an interface designer, not the driver programmer, and this task seems to be pretty low-level. I would be grateful for any suggestion and tip!

• Different Scala Actor Implementations Overview

  - by Stefan K.

  I'm trying to find the 'right' actor implementation for my thesis. I realized there is a bunch of them and it's a bit confusing to pick one. Personally I'm especially interested in remote actors, but I guess a complete overview would be helpful to many others. This is a pretty general question, so feel free to answer just for the implementation you know about. I know about the following Scala Actor implementations (SAI). Please add the missing ones. Scala 2.7 (difference to) Scala 2.8 Akka (http://www.akkasource.org/) Lift (http://liftweb.net/) Scalaz (http://code.google.com/p/scalaz/) What are the target use-cases for these SAIs (lightweight vs. "heavy" enterprise framework)? do they support remote actors? What shortcomings do remote actors have in the SAIs? How is their performace? How active is there community? How easy are they to get started? How good is the documentation? How easy are they to extend? How stable are they? Which projects are using them? What are their shortcomings? What are their design principles? Are they thread based or event based (receive/ react) or both? Nested receiveS hotswapping the Actor’s message loop

• Is Git ready to be recommended to my boss?

  - by Mike Weller

  I want to recomment Git to my boss as a new source control system, since we're stuck in the 90s with VSS (ouch), but are the tools and 3rd party support good enough yet? Specifically I'm talking about GUI front-ends similar to TortoiseSVN, decent visual diff/merge support, as well as stuff like email commit notifications and general support from 3rd parties like IDEs and build systems. Even though this will be used by programmers, we really need this kind of stuff in our team. I don't want to leave everyone stuck with a new tool, and even a new source control paradigm (distributed), with nothing but a command-line app and some online tutorials. This would be a step backwards. So what do you think... is Git ready? What decent tools exist for Git and what third party development apps support it? EDIT: My original question was pretty vague so I'm updating it to specifically ask for a list of available tools and 3rd party support for Git. Maybe we can get a community wiki post with a list of stuff. I also do not consider 'use subversion' to be an adequate answer. There are other reasons to use a distributed source control system other than offline editing - private and cheap branches being one of them.

• Exposed onsite vs IFD deployments for MS Dynamics CRM

  - by Greg McGuffey

  I'm working for the first time on a MS Dyanmics CRM 4.0 project. Our company has a high number of remote employees and even more remote consultants. As such it will be necessary to make the CRM solution available over the internet. As near as I can tell, I have three options: Have everyone use a VPN to access an intranet site (typical onsite deployment). However, we have found that VPNs are far from trouble free and cause many support issues. We avoid them like the plague. Use IFD to expose the CRM on the internet. I don't know much about this except that the URL will be different than the onsite URL, which could cause some headaches (see below). Expose the CRM site by opening the site to the internet, using SSL to encrypt traffic. We currently do this with our MS sharepoint sites. I'm not sure how secure this would be (one of the reasons for this question). I'd like to avoid using both the onsite intranet deployment and the IFD together for a couple of reasons. One of the requests for the solution is use email to notify users that they've been assigned a task, and include the URL to the task within the email. For this reason. If both deployments are used, then I'll need to include two URLs and the user would need to know which to use. Which leads to the second reason, the main users of the solution split time between being in the office and being remote. Thus they would need to access the solution two different ways, and know when to use which. Bad. So, what are the advantages/disadvantages of any of these methods? Any other options? Is there any issue using IFD from within the intranet? Security issues? Thanks!

• What is your favorite API developer community site? And why? [closed]

  - by whatupwilly

  There are a lot of great sites out there that offer good documentation, tools, tips, best-practices, sample code, etc. for the API's they are publishing. A sample: http://apiwiki.twitter.com http://developer.netflix.com/ http://developers.facebook.com/ https://affiliate-program.amazon.com/gp/advertising/api/detail/main.html http://code.google.com/ http://remix.bestbuy.com/ http://www.flickr.com/services/api/misc.overview.html http://products.wolframalpha.com/api/webserviceapi.html There are some no-brainers that I think a good developer site should have: Hi level introduction Quick start guide API specific details - showing example request and responses Links to sample code and/or 3rd party libraries Developer registration (e.g. get an API key) Blog But what about some other things: Online-Forum or Msg Board vs. Google Group (or similar) Galleries/ShowCases - spotlighting great apps built on the API - who has done nice galleries? Community Wiki - How do people feel about letting the community have edit rights on API documentation pages Online testing tools (like Facebook has a lot of nice interactive tools to simulate request/responses) What are some packages that you would recommend to put this all together: pbwiki Google Group pages MediaWiki API vendor package such as Sonoa Systems that offers a customizable developer portal So, to summarize: What are some other great API developer portals out there What are some nice features you like on them Any recommendations on what to use to build these features out Thanks, Will Zappos.com Public API (soon to launch) Product Manager

• Eclipse 3.7 Classic Nightmare - ADT Installation

  - by Cal

  I've been trying to install the ADT for Eclipse Classic 3.7 to no avail. From what I've seen on searches, the general consensus seems to be to update the software, but alas I cannot do that, either. BELOW: An example of the error message received when trying to update Eclipse, or when attempting to install from a web location. Some sites could not be found. See the error log for more detail. Unable to read repository at http://download.eclipse.org/eclipse/updates/3.7/content.xml. Cannot assign requested address: JVM_Bind I followed the troubleshooting recommendations of Google/Android's developer section, and attempted to install ADT via archive. BELOW: The resulting error from attempting to install via archive. Cannot complete the install because one or more required items could not be found. Software being installed: Android Development Tools 11.0.0.v201105251008-128486 (com.android.ide.eclipse.adt.feature.group 11.0.0.v201105251008-128486) Missing requirement: Android Development Tools 11.0.0.v201105251008-128486 (com.android.ide.eclipse.adt.feature.group 11.0.0.v201105251008-128486) requires 'org.eclipse.gef 0.0.0' but it could not be found Now, from what I hear, the inability to update/install via Internet seems to be a proxy-related issue, however I don't believe that I'm under any such thing (I'm just using my computer connected to my home network for this). I'm using the most up-to-date versions of anything I can think of (ADT, Eclipse, SDK Tools etc). I'm using Windows 7 Ultimate 64bit, and am using the 64bit version of Eclipse Classic.

• Code Coverage tool for BlackBerry

  - by Skrud

  I'm looking for a code coverage tool that I can use with a BlackBerry application. I'm using J2ME-Unit for Unit Testing and I want to see how much of my code is being covered by my tests. I've tried using Cobertura for J2ME but after days of wrestling with it I failed to get any results from it. (I believe that the instrumentation is un-done by the RAPC compilation). And despite this message, the project seems to be dead. I've looked at JInjector but the project seems very incomplete. There is little (if any) documentation and although it claims to be able to work with BlackBerry projects, I haven't seen any places where it has been used for that purpose. I've played with the project quite a bit but to no avail. I've also tried the "Coverage" view in the BlackBerry JDE, even though I use Eclipse for development. The view stays permanently blank, regardless of clicking "Refresh" and running the application from the JDE. I've looked at most of the tools on this SO thread, but they won't work with J2ME/BlackBerry projects. Has anyone had any success with any code coverage tools on the BlackBerry? If so, what tools have you used? How have you used them? If anyone has managed to get JInjector or Cobertura for J2ME to work with a BlackBerry project, what did you have to do to get it working?

• Clicking on MenuItem without clicking on the text

  - by pringlesinn

  I've got a Menu, and I want to click on the menu, but not on the text if you guys know what i mean. The MenuItem has a border, or something like this, but when I click on it it won't redirect to the page I want unless I click on text. Is it possible to click on the whole "Button" and redirect or do what is need to do? My menu is like this: <rich:dropDownMenu showDelay="250" hideDelay="0" submitMode="none"> <f:facet name="label">Tools</f:facet> <rich:menuItem> <s:link view="/pages/tools/ppaParameters/PpaParametersEdit.xhtml" value="Parameters" id="PpaParametersId" includePageParams="false" propagation="none"/> </rich:menuItem> <rich:menuGroup value="Security"> <rich:menuItem> <s:link view="/pages/tools/security/ppaModule/PpaModuleEdit.xhtml" value="Module" id="PpaModuleId" includePageParams="false" propagation="none" /> </rich:menuItem> </rich:menuGroup> </rich:dropDownMenu> There's an example. I need to click on text to make it work out.

• Java - Problem in deploying Web Application

  - by Yatendra Goel

  I have built a Java Web Application and packed it in a .war file and tested it on my local tomcat server and it is running fine. But when I deployed it on my client's server, it is showing an error. According to the remote server (my client's server), it is not finding a tld file packed in a jar file which I had placed in WEB-INF/lib directory. But when I checked the WEB-INF/lib directory for the jar file, i found that it was there. The contents of META-INF/MANIFEST.MF is as follows: Manifest-Version: 1.0 Class-Path: I think that there is no need to explicitly mention the classpath of WEB-INF/lib directory as it is in the classpath of any web application by default. Then, why the server can't find the jar file in the lib directory when I deployed it on a remote server and why it is working when I deployed the same application on my local server. I posted a question for this at http://stackoverflow.com/questions/2441254/struts-1-struts-taglib-jar-is-not-being-found-by-my-web-application but found that the problem is unusual as nobody could answer it. So my questions are as follows: Q1. Is WEB-INF/lib still remains on the classpath if I leave the classpath entry blank as shown above in the MANIFEST.MF file or I should delete the classpath entry completely from the file or I should explicitly enter Class-Path: /WEB-INF/lib as the classpath entry? Q2. I have JSP pages, Servlets and some helper classes in the web application. Jsp pages are located at the root. Servlets and helper classes are located in WEB-INF/classes folder. So Is there any problem if my helper classes are located in the WEB-INF/classes folder? Note: Please note that this question is not same as my previous question. It is a follow-up question of my previous question. Both the servers (local and remote) are tomcat servers.

• Best practice to structure large html-based project

  - by AntonAL

  I develop Rails based website, enjoying using partials for some common "components" Recently, i faced a problem, that states with CSS interference. Styles for one component (described in css) override styles for another components. For example, one component has ... <ul class="items"> ... and another component has it too. But that ul's has different meaning in these two components. On the other hand, i want to "inherit" some styles for one component from another. For example: Let, we have one component, called "post" <div class="post"> <!-- post's stuff --> <ul class="items"> ... </ul> </div And another component, called "new-post": <div class="new-post"> <!-- post's stuff --> <ul class="items"> ... </ul> <!-- new-post's stuff --> <div class="tools">...</div> </div Post and new-post have something similar ("post's stuff") and i want to make CSS rules to handle both "post" and "new-post" New post has "subcomponents", for example - editing tools, that has also: <ul class="items"> This is where CSS rules starting to interfer - some rules, targeted for ul.items (in post and new-post) applies subcomponent of new-post, called "tools" On the one hand - i want to inherit some styles On the other hand, i want to get better incapsulation What are the best practices, to avoid such kind of problems ?

• Message driven bean not responding until client method is complete

  - by poijoi

  Hi, I have a MDB deployed on Jboss 4.2.2 and a client on the same server that produces messages and expects a reply from the MDB via a temporary queue created before the message is sent. When I run the client, I see that it creates the message, puts it in the queue and waits for the reply (no problem so far) ... but when I check in the logs I see that the timeout is reached and no response is received. When the timeout occurs and the client's method is complete the MDB starts processing the message that should have been processed the moment the client put it in the queue. As a consequence of this timing issue, when the MDB tries to reply to the temp queue, it fails since the client is already gone. If I run the same client from a remote server, I have no problem... The MDB picks up the message from the queue right away and the client receives its response right after the processing is complete. I'm using container managed transactions. I suspect it has something to do with that... I think the client's "send message/receive reply" might be all be considered a transaction before it commits to put the message in the queue... but I'm not sure if this is correct. If this is the case, why did I not see the same behavior from the remote client? is client managed transaction the default setting and that's what my remote server was using? Any idea how to fix this? Thanks in advance! PJ

• Why is "origin/HEAD" shown when running "git branch -r"?

  - by Ben Hamill

  When you run git branch -r why the blazes does it list origin/HEAD? For example, there's a remote repo on GitHub, say, with two branches: master and awesome-feature. If I do git clone to grab it and then go into my new directory and list the branches, I see this: $ git branch -r origin/HEAD origin/master origin/awesome-feature Or whatever order it would be in (alpha? I'm faking this example to keep the identity of an innocent repo secret). So what's the HEAD business? Is it what the last person to push had their HEAD pointed at when they pushed? Won't that always be whatever it was they pushed? HEADs move around... why do I care what someone's HEAD pointed at on another machine? I'm just getting a handle on remote tracking and such, so this is one lingering confusion. Thanks! EDIT: I was under the impression that dedicated remote repos (like GitHub where no one will ssh in and work on that code, but only pull or push, etc) didn't and shouldn't have a HEAD because there was, basically, no working copy. Not so?

• Deploying a WAR to tomcat only using a context descriptor

  - by DanglingElse

  i need to deploy a web application in WAR format to a remote tomcat6 server. The thing is that i don't want to do that the easy way, meaning not just copy/paste the WAR file to /webapps. So the second choice is to create a unique "Context Descriptor" and pointing this out to the WAR file. (Hope i got that right till here) So i have a few questions: Is the WAR file allowed to be anywhere in the file system? Meaning can i copy the WAR file anywhere in the remote file system, except /webapps or any other folder of the tomcat6 installation? Is there an easy way to test whether the deployment was successful or not? Without using any browser or anything, since i'm reaching to the remote server only via SSH and terminal. (I'm thinking ping?) Is it normal that the startup.sh/shutdown.sh don't exist? I'm not the admin of the server and don't know how the tomcat6 is installed. But i'm sure that in my local tomcat installations these files are in /bin and ready to use. I mean you can still start/restart/stop the tomcat etc., but not with the these -standard?- scripts. Thanks a lot.

• Searching Natural Language Sentence Structure

  - by Cerin

  What's the best way to store and search a database of natural language sentence structure trees? Using OpenNLP's English Treebank Parser, I can get fairly reliable sentence structure parsings for arbitrary sentences. What I'd like to do is create a tool that can extract all the doc strings from my source code, generate these trees for all sentences in the doc strings, store these trees and their associated function name in a database, and then allow a user to search the database using natural language queries. So, given the sentence "This uploads files to a remote machine." for the function upload_files(), I'd have the tree: (TOP (S (NP (DT This)) (VP (VBZ uploads) (NP (NNS files)) (PP (TO to) (NP (DT a) (JJ remote) (NN machine)))) (. .))) If someone entered the query "How can I upload files?", equating to the tree: (TOP (SBARQ (WHADVP (WRB How)) (SQ (MD can) (NP (PRP I)) (VP (VB upload) (NP (NNS files)))) (. ?))) how would I store and query these trees in a SQL database? I've written a simple proof-of-concept script that can perform this search using a mix of regular expressions and network graph parsing, but I'm not sure how I'd implement this in a scalable way. And yes, I realize my example would be trivial to retrieve using a simple keyword search. The idea I'm trying to test is how I might take advantage of grammatical structure, so I can weed-out entries with similar keywords, but a different sentence structure. For example, with the above query, I wouldn't want to retrieve the entry associated with the sentence "Checks a remote machine to find a user that uploads files." which has similar keywords, but is obviously describing a completely different behavior.

• UML diagrams that are actually pretty?

  - by Borek

  I'm looking for a diagramming software that would produce good looking output. It doesn't need to support everything (or even much) from UML, is doesn't need to have code engineering functions or anything, it just needs to produce visually interesting output. Here is a couple of samples of products that I consider ugly / not good enough: Visio with default UML stencils (didn't find better looking ones), Enterprise Architect, Dia, ArgoUML and many other "professional" UML tools. A couple of visually compelling tools that I considered (but found issues with): Visual Studio class diagrams - just for .NET classes but the output is miles better than what UML tools typically produce NClass - similar to VS's class diagrams but I could not find the "pretty", blue skin anywhere yuml.me - very nice but lacking some advanced layout options. I have to say that I find their style almost ideal for high-level diagrams - they look sketchy which is good. Balsamiq - I think Joel used this for hginit.com and I liked it. However, it's not suited for creating software diagrams so I can imagine it would be quite a lot of work MS Word has actually quite a good graphics engine but I'd rather leave this as a choice of the last resort I'd be grateful for any good tips.

• Google Analytics version 3 - How to apply it correctly?

  - by ephramd

  I've added google analytics to my app with the intention of obtaining information about the screens you and send custom events. I am obtained duplicate content ... Also I get different results: "com.package.app.MainScreen" - 300 views and "Main Screen" - 200 views I am interested to get only follow up with the custom name of the activity and not the package. And in any case, because both show different results? public class MainScreen extends Activity { private static final String GA_PROPERTY_ID = "UA-12345678-9"; private static final String SCREEN_LABEL = "Main Screen"; Tracker mTracker; EasyTracker easyTracker; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main_screen); mTracker = GoogleAnalytics.getInstance(this).getTracker(GA_PROPERTY_ID); mTracker.set(Fields.SCREEN_NAME, SCREEN_LABEL); // For Custom Name from activity mTracker.send(MapBuilder.createAppView().build()); easyTracker = EasyTracker.getInstance(this); // Analytics Events ... easyTracker.send(MapBuilder.createEvent("MainScreen", "Play", category.get(1), null).build()); //AnalyticsEvents ... } @Override public void onStart() { super.onStart(); EasyTracker.getInstance(this).activityStart(this); } @Override public void onStop() { super.onStop(); EasyTracker.getInstance(this).activityStop(this); } } And analytics.xml: <?xml version="1.0" encoding="utf-8" ?> <resources xmlns:tools="http://schemas.android.com/tools" tools:ignore="TypographyDashes"> <!--Replace placeholder ID with your tracking ID--> <string name="ga_trackingId">UA-12345678-9</string> <!--Enable automatic activity tracking--> <bool name="ga_autoActivityTracking">true</bool> <!--Enable automatic exception tracking--> <bool name="ga_reportUncaughtExceptions">true</bool> </resources> Google Analytics Dev Guide

• Ensuring quality of your software and code

  - by Filip Ekberg

  When I usually write code I follow some guidelines to ensure that my code has a certain standard and I as any other developer try to ensure that my code and software is of quality. Try to focus on the programming and not the understanding of the domain or any other pre-programming steps. These are the following steps I live by: Writing unit tests Make it fail ( no code ) Make it Work ( working code ) Analysing abstraction Extracting methods Exteract interfaces Refactoring In addition to the above which is a part of refactoring, I also try to refactor the code with good tools such as ReSharper, CodeRush or others. The question; What is the next step? Commenting the code is trivial and shouldn't even have to be mentioned, but updated comments and xml-comments where it's needed / everywhere is something that I try to have. But all the above helps he ensure that other developers might understand my code, that the code has some sort of quality and follows naming standards. It does however not ensure any product quality. I am looking for tools for post-development quality ensurance, such as profilers and how one would use these tools to increase product quality.

• joomla! migration

  - by tim

  I have a Joomla! installation on a remote site and I want to run it locally. I'm running Joomla! locally on a Mac through a standard MAMP installation: Joomla 1.5.12 PHP 5.2.6 MySQL 5.0.41 Apache 2.0.59 OS X 10.5.8 I've added a configuration file to the local Joomla! directory with all the correct local settings, database name, database user-name, database password etc. etc. I've tried a lot of different settings. I've also recreated the remote database locally, ensuring everything copied correctly. I followed a few different sets of instructions with roughly the same steps on how to do the migration. All of the above has not worked for me; at best I get bits of text from the site rendered in the browser. Other times I get SQL errors. What I want is for an already set up remote Joomla! installation to run on my own local machine. Does anyone have any advice as to how to get this working, it'd be very much appreciated? Thanks.
