• Will Learning C++ Help for Building Fast/No-Additional-Requirements Desktop Applications?

  - by vito

  Will learning C++ help me build native applications with good speed? Will it help me as a programmer, and what are the other benefits? The reason why I want to learn C++ is because I'm disappointed with the UI performances of applications built on top of JVM and .NET. They feel slow, and start slow too. Of course, a really bad programmer can create a slower and sluggish application using C++ too, but I'm not considering that case. One of my favorite Windows utility application is Launchy. And in the Readme.pdf file, the author of the program wrote this: 0.6 This is the first C++ release. As I became frustrated with C#’s large .NET framework requirements and users lack of desire to install it, I decided to switch back to the faster language. I totally agree with the author of Launchy about the .NET framework requirement or even a JRE requirement for desktop applications. Let alone the specific version of them. And some of the best and my favorite desktop applications don't need .NET or Java to run. They just run after installing. Are they mostly built using C++? Is C++ the only option for good and fast GUI based applications? And, I'm also very interested in hearing the other benefits of learning C++.

• Update SQL Server 2000 to SQL Server 2008: Benefits please?

  - by Ciaran Archer

  Hi there I'm looking for the benefits of upgrading from SQL Server 2000 to 2008. I was wondering: What database features can we leverage with 2008 that we can't now? What new TSQL features can we look forward to using? What performance benefits can we expect to see? What else will make management go for it? And the converse: What problems can we expect to encounter? What other problems have people found when migrating? Why fix something that isn't (technically) broken? We work in a Java shop, so any .NET / CLR stuff won't rock our world. We also use Eclipse as our main development so any integration with Visual Studio won't be a plus. We do use SQL Server Management Studio however. Some background: Our main database machine is a 32bit Dell Intel Xeon MP CPU 2.0GHz, 40MB of RAM with Physical Address Extension running Windows Server 2003 Enterprise Edition. We will not be changing our hardware. Our databases in total are under a TB with some having more than 200 tables. But they are busy and during busy times we see 60-80% CPU utilisation. Apart form the fact that SQL Server 2000 is coming close to end of life, why should we upgrade? Any and all contributions are appreciated!

• Flex Modules vs RSL

  - by nil

  Hi, I'm a little bit confused about when is better to use Flex Modules or RSL libriaries (in Flex 3.5). My goal is split my project in several unit projects, so I can test and work separately. Let's assume I have a Customer app and Vendor app. I also have a front-end panel with two buttons. Each button launches Customer app or Vendor app. These applications make different things. They share some .as functions and common components, too. I understand that if I make a main project (for user login and to show a first panel) and two modules (customer, vendor) I must have all that components in my Eclipse project, isn't it? Instead of doing modules, should I create SWC for Vendor and other for Customer app and call from main app by using RSL? So, which option is more suitable? What do you advise me? Which are the trade-offs of each option? On the other side, this flex application is integrated with Java through Blaze and ibatis for persistence managment, and hold by a web apache server. I considered also to create independent war files to keep this indpendence, but I thought this do not optimize flex code. I'm right? Thank you. Nil

• The Implications of Modern Day Software Development Abstractions

  - by Andreas Grech

  I am currently doing a dissertation about the implications or dangers that today's software development practices or teachings may have on the long term effects of programming. Just to make it clear: I am not attacking the use abstractions in programming. Every programmer knows that abstractions are the bases for modularity. What I want to investigate with this dissertation are the positive and negative effects abstractions can have in software development. As regards the positive, I am sure that I can find many sources that can confirm this. But what about the negative effects of abstractions? Do you have any stories to share that talk about when certain abstractions failed on you? The main concern is that many programmers today are programming against abstractions without having the faintest idea of what the abstraction is doing under-the-covers. This may very well lead to bugs and bad design. So, in you're opinion, how important is it that programmers actually know what is going below the abstractions? Taking a simple example from Joel's Back to Basics, C's strcat: void strcat( char* dest, char* src ) { while (*dest) dest++; while (*dest++ = *src++); } The above function hosts the issue that if you are doing string concatenation, the function is always starting from the beginning of the dest pointer to find the null terminator character, whereas if you write the function as follows, you will return a pointer to where the concatenated string is, which in turn allows you to pass this new pointer to the concatenation function as the *dest parameter: char* mystrcat( char* dest, char* src ) { while (*dest) dest++; while (*dest++ = *src++); return --dest; } Now this is obviously a very simple as regards abstractions, but it is the same concept I shall be investigating. Finally, what do you think about the issue that schools are preferring to teach Java instead of C and Lisp ? Can you please give your opinions and your says as regards this subject? Thank you for your time and I appreciate every comment.

• Worklight console app, update

  - by jarkko

  We're using Worklight 6.1.0.0 / WebSphere 8.0.0.2 (ND/aix). This seemed pretty close to my question too, but for version 6.0. I've successfully done uninstall/install to our worklight console war package. However, there is some extra work on re-deploying adapters and such. I was looking for a way to just update the console. Among the ant tasks there is a target 'minimal-update', which sounds like what I'm looking for (is it?). However when all other pieces fell into place, I have an error for mapping the datasources: ADMA0007E: A validation error occurred in task Mapping resource references to resources. The Java Naming and Directory Interface (JNDI) name is not specified for resource reference jdbc/WorklightDS in module Worklight with EJB name . Contents of the 'minimal-update' task is pretty much the same as for 'install'. I tried that as update from websphere admin console (but i should use the ant task - right?), that gave me a wizard screen to map jdbc/WorklightDS from package to jdbc/WorklightDS on server. This left me wondering how could I tell this using the ant task.

• View layout after setvisibility

  - by user1478296

  I've got problem with setting visibility to relative layout. I have part of big layout in relativelayout and below that next TextView. But in my code, when myRelativeLayout.setVisibility(View.GONE); is called, TextView which is below that did not appear. I tried several ways to rearange layout, but i need that textview under it. Thanks My XML: <merge xmlns:android="http://schemas.android.com/apk/res/android" > <ScrollView android:id="@+id/scrollView_liab_ra_flipper_04" android:layout_width="fill_parent" android:layout_height="wrap_content" > <RelativeLayout android:id="@+id/linearLayout_liab_ra_flipper_04" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <TextView android:id="@+id/someTextView" android:text="Something" /> <!-- This relative layout should be removable --> <RelativeLayout android:id="@+id/vg_liab_ra_04_flipper_car_container_visible" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/someTextView" > <TextView android:id="@+id/tv_1" style="@style/WhiteFormText" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="15dp" android:layout_marginTop="2dp" android:text="@string/licence_plate_counter" > </TextView> <EditText android:id="@+id/et_1" style="@style/WhiteFormField" android:layout_below="@+id/tv_1" android:hint="@string/licence_plate_hint" > </EditText> </RelativeLayout> <!-- This textview is not visible if relative layout is gone --> <TextView android:id="@+id/tv_liab_ra_04_flipper_mandat" style="@style/WhiteFormTextHint" android:layout_below="@+id/vg_liab_ra_04_flipper_car_container_visible" android:layout_marginBottom="15dp" android:text="@string/mandatory_field" > </TextView> </RelativeLayout> </ScrollView> </merge> Java Code: private void hideCar() { if (!accident.getParticipant(0)) { rlCarContainer.setVisibility(View.GONE); } else { rlCarContainer.setVisibility(View.VISIBLE); } }

• Cocoa: Using UNIX based commands to write a file

  - by BryCry

  I'm looking for help with a program im making. I create a *.sh file as follows: SVN_StatGenAppDelegate.h: NSWindow *window; NSTask *touch; NSArray *touchArguments; NSString *svnURLStr; NSString *SVNStatStr; NSString *destDirStr; SVN_StatGenApplDelegate.m: NSString *locationStr = [NSString stringWithFormat:@"%@/exec.sh", destDirStr]; NSLog(@"%@", locationStr); touch = [[NSTask alloc] init]; [touch setLaunchPath:@"/usr/bin/touch"]; touchArguments = [NSArray arrayWithObjects:locationStr, nil]; [touch setArguments:touchArguments]; [touch launch]; This works, i get a file called exec.sh created in the location i craete with the destDirStr. Now is my next question, i need to get that file filled with the following: svn co http://repo.com/svn/test C:\users\twan\desktop\pres\_temp cd C:\users\twan\desktop\pres\_temp svn log -v --xml > logfile.log copy C:\users\twan\desktop\statsvn.jar C:\users\twan\desktop\pres\_temp cd .. java -jar _temp\statsvn.jar C:\users\twan\desktop\pres\_temp/logfile.log C:\users\twan\desktop\pres\_temp rmdir /s /Q _temp The actual idea is that this script is written into the sh file, and all the _temp and other locations are replaced by the vars i get from textfields etc. so c:\users\twan\desktop\pres_temp would be a var called tempDirStr that i get from my inputfields. (i know these cmomands and locations are windows based, im doing this with a friend and he made a .net counterpart of the application. Can you guys help me out?:D thanks in advance!

• web service client authentication

  - by Jack

  I want to consume Java based web service with c#.net client. The problem is, I couldnt authenticate to the service. it didnt work with this: mywebservice.Credentials = new System.Net.NetworkCredential(userid, userpass); I tried to write base class for my client method. public class ClientProtocols : SoapHttpClientProtocol { protected override WebRequest GetWebRequest(Uri uri) { System.Net.WebRequest request = base.GetWebRequest(uri); if (null != Credentials) request.Headers.Add("Authorization", GetAuthHeader()); return request; } protected override WebResponse GetWebResponse(WebRequest request) { WebResponse response = base.GetWebResponse(request); return response; } private string GetAuthHeader() { StringBuilder sb = new StringBuilder(); sb.Append("Basic "); NetworkCredential cred = Credentials.GetCredential(new Uri(Url), "Basic"); string s = string.Format("{0}:{1}", cred.UserName, cred.Password); sb.Append(Convert.ToBase64String(Encoding.ASCII.GetBytes(s))); return sb.ToString(); } } How can I use this class and authorize to the web service? Thanks.

• Static code analysis for new language. Where to start?

  - by tinny

  I just been given a new assignment which looks like its going to be an interesting challenge. The customer is wanting a code style checking tool to be developed for their internal (soon to be open sourced) programming language which runs on the JVM. The language syntax is very Java like. The customer basically wants me to produce something like checkstyle. So my question is this, how would you approach this problem? Given a clean slate what recommendations would you make to the customer? I think I have 3 options Write something from scratch. Id prefer not to do this as it seems like this sort of code analysis tool problem has been solved so many times that there must be a more "framework" or "platform" orientated approach. Fork an existing code style checking tool and modify the parsing to fit with this new language etc etc Extend or plug into an existing static code analysis tool. (maybe write a plugin for Yasca?) Maybe you would like to share your experiences in this area? Thanks for reading

• AnkhSVN: Cannot checkout Subsolution due to existing "versioned" folder

  - by lostiniceland

  Hello Everyone I am using Subversion since quite some time for Java-Development and I have setup a repository on my local NAS. Since I have a MSDN subscription via my company I recently installed Visual Studio 2010 to do a small project with .NET. According to some "best-practices" my project folder looks like the following. MySolution main.sln Services services.sln Service A files Service A Test files View projectfiles Persistence persistence.sln PersistenceXml files PersistenceXml Test files PersistenceDB files PersistenceDB Test files The idea is, that the main.sln only contains the projects for the application, meaning no test projects. The subsolutions, contain the project(s) and their corresponding testprojects. I was able to put all those projects under versioncontrol with AnkhSVN, so I have the same structure there in my trunk. Commiting changes was also no problem. Now I would like to check the this out on another machine. I was able to check out the main.sln which downloaded everything that was inside this solution. It skipped the services.sln, persistence.sln and all the test-projects. Until now everything is fine. Now, here comes the problem: when I am tryting to check out the subsolution (eg. services.sln) I get an error, I think it was UnsupportedOperation. I guess this happens because ankhsvn is tryting to download the folder Service A again and create ist hidden .svn folder which is already present. The only workaround I can think of by now is installing Tortoise SVN and check out the whole thing at once. It would be nicer though to have everything from within VS. Does anyone know how I can solve this? Is another client the only solution?

• Is Accessing USB from web application for cross browser cross os possible at all ?

  - by Ved

  Hey Guys, I am wondering if there is anyway we can achieve this. I heard different things about Silverlight 4 , Java Script or Active X control but not seen any demo of code for any of them. Does anyone know any web component that is available or how to write one. We really like capture client's USB drive via Web and read/write data on it. This has to work for ANY Operating system in Any web browser. Thanks UPDATED What about WPF in browser mode...I read that I can host my wpf apps inside browser and sort of like smart client. Here is a great example of doing this via silverlight 4 but author mentions about possibility of accessing USB on MAC via 1) Enable executing AppleScripts. This option will let us have the same amount of control on a mac machine as we do on a windows machine. 2) Add an overload to ComAutomationFactory.CreateObject() that calls the “Tell Application” command under the scenes and gets a AppleScript object. This option would work extremely well for Office automation. For any other operating system feature, you’ll have to code OS access twice.  I did not quite understand it. Has any tried this ?

• How to (unit-)test data intensive PL/SQL application

  - by doom2.wad

  Our team is willing to unit-test a new code written under a running project extending an existing huge Oracle system. The system is written solely in PL/SQL, consists of thousands of tables, hundreds of stored procedures packages, mostly getting data from tables and/or inserting/updating other data. Our extension is not an exception. Most functions return data from a quite complex SELECT statementa over many mutually bound tables (with a little added logic before returning them) or make transformation from one complicated data structure to another (complicated in another way). What is the best approach to unit-test such code? There are no unit tests for existing code base. To make things worse, only packages, triggers and views are source-controlled, table structures (including "alter table" stuff and necessary data transformations are deployed via channel other than version control). There is no way to change this within our project's scope. Maintaining testing data set seems to be impossible since there is new code deployed to the production environment on weekly basis, usually without prior notice, often changing data structure (add a column here, remove one there). I'd be glad for any suggestion or reference to help us. Some team members tend to be tired by figuring out how to even start for our experience with unit-testing does not cover PL/SQL data intensive legacy systems (only those "from-the-book" greenfield Java projects).

• Projective transformation

  - by mcwehner

  Given two image buffers (assume it's an array of ints of size width * height, with each element a color value), how can I map an area defined by a quadrilateral from one image buffer into the other (always square) image buffer? I'm led to understand this is called "projective transformation". I'm also looking for a general (not language- or library-specific) way of doing this, such that it could be reasonably applied in any language without relying on "magic function X that does all the work for me". An example: I've written a short program in Java using the Processing library (processing.org) that captures video from a camera. During an initial "calibrating" step, the captured video is output directly into a window. The user then clicks on four points to define an area of the video that will be transformed, then mapped into the square window during subsequent operation of the program. If the user were to click on the four points defining the corners of a door visible at an angle in the camera's output, then this transformation would cause the subsequent video to map the transformed image of the door to the entire area of the window, albeit somewhat distorted.

• Facebook offline access step-by-step

  - by Ben

  After searchinge litteraly 1 day on fb and google for an up-to-date and working way to do something seemingly simple: I am looking for a step-by-step explanation to get offline_access for a user for a facebook app and then using this (session key) to retrieve offline & not within a browser friends & profile data. Preferrably doing this in the Fb Java API. Thanks. And yes I did check the facebook wiki. Update: Anyone? this: http://www.facebook.com/authorize.php?api_key=<api-key>&v=1.0&ext_perm=offline_access gives me offline_Access, however how to retrieve the session_key? Why can't facebook just do simple documentation, I mean there are like 600 people working there? The seemingly same question: http://stackoverflow.com/questions/617043/getting-offlineaccess-to-work-with-facebook Does not answer how to retrieve the session key Edit: I am still stuck with that. I guess nobody really tried such a batch access out yet...

• How to highlight the new created file in JTree

  - by newbie123

  I want to make it like when I click a button, it will create a new file. Then the jTree will highlight the new file. Below are my code. Currently I create new file, i will show the new file but no highlight the file. class FileTreeModel implements TreeModel { private FileNode root; public FileTreeModel(String directory) { root = new FileNode(directory); } public Object getRoot() { return root; } public Object getChild(Object parent, int index) { FileNode parentNode = (FileNode) parent; return new FileNode(parentNode, parentNode.listFiles()[index].getName()); } public int getChildCount(Object parent) { FileNode parentNode = (FileNode) parent; if (parent == null || !parentNode.isDirectory() || parentNode.listFiles() == null) { return 0; } return parentNode.listFiles().length; } public boolean isLeaf(Object node) { return (getChildCount(node) == 0); } public int getIndexOfChild(Object parent, Object child) { FileNode parentNode = (FileNode) parent; FileNode childNode = (FileNode) child; return Arrays.asList(parentNode.list()).indexOf(childNode.getName()); } public void valueForPathChanged(TreePath path, Object newValue) { } public void addTreeModelListener(TreeModelListener l) { } public void removeTreeModelListener(TreeModelListener l) { } } class FileNode extends java.io.File { public FileNode(String directory) { super(directory); } public FileNode(FileNode parent, String child) { super(parent, child); } @Override public String toString() { return getName(); } } jTree = new JTree(); jTree.setBounds(new Rectangle(164, 66, 180, 421)); jTree.setBackground(SystemColor.inactiveCaptionBorder); jTree.setBorder(BorderFactory.createTitledBorder(null, "", TitledBorder.LEADING, TitledBorder.TOP, new Font("Arial", Font.BOLD, 12), new Color(0, 0, 0))); FileTreeModel model = new FileTreeModel(root); jTree.setRootVisible(false); jTree.setModel(model); expandAll(jTree); public void expandAll(JTree tree) { int row = 0; while (row < tree.getRowCount()) { tree.expandRow(row); row++; } }

• wsdl xml parsing , maxlength problem after encoding of text

  - by MichaelD

  We are working together with another firm. our application communicates with the other application through WCF on our side and a custom implemented java wsdl handler on the other side. They specify the wsdl format and one of the rules is that a specific string cannot contain more then 15 characters. (normally it's 60, but i take 15 for easy example reasons) When we try to send the following string to them we get an error that the string is too long according to the wsdl: "example & test" this is a string of 14 characters, so it should be allowed the microsoft wcf parser translates this to "example &amp; test" . This encoded string is 18 characters long. Now what is the standaard behavior to check a maxlength defined in a message? Is it the encoded message or the decoded message? I would think it's the decoded message , but i ain't sure. If it is the encoded message, how should we handle this so we would know how we have to split the string?

• Looking to reimplement build toolchain from bash/grep/sed/awk/(auto)make/configure to something more

  - by wash

  I currently maintain a few boxes that house a loosely related cornucopia of coding projects, databases and repositories (ranging from a homebrew *nix distro to my class notes), maintained by myself and a few equally pasty-skinned nerdy friends (all of said cornucopia is stored in SVN). The vast majority of our code is in C/C++/assembly (a few utilities are in python/perl/php, we're not big java fans), compiled in gcc. Our build toolchain typically consists of a hodgepodge of make, bash, grep, sed and awk. Recent discovery of a Makefile nearly as long as the program it builds (as well as everyone's general anxiety with my cryptic sed and awking) has motivated me to seek a less painful build system. Currently, the strongest candidate I've come across is Boost Build/Bjam as a replacement for GNU make and python as a replacement for our build-related bash scripts. Are there any other C/C++/asm build systems out there worth looking into? I've browsed through a number of make alternatives, but I haven't found any that are developed by names I know aside from Boost's. (I should note that an ability to easily extract information from svn commandline tools such as svnversion is important, as well as enough flexibility to configure for builds of asm projects as easily as c/c++ projects)

• Design patterns for Agent / Actor based concurrent design.

  - by nso1

  Recently i have been getting into alternative languages that support an actor/agent/shared nothing architecture - ie. scala, clojure etc (clojure also supports shared state). So far most of the documentation that I have read focus around the intro level. What I am looking for is more advanced documentation along the gang of four but instead shared nothing based. Why ? It helps to grok the change in design thinking. Simple examples are easy, but in a real world java application (single threaded) you can have object graphs with 1000's of members with complex relationships. But with agent based concurrency development it introduces a whole new set of ideas to comprehend when designing large systems. ie. Agent granularity - how much state should one agent manage - implications on performance etc or are their good patterns for mapping shared state object graphs to agent based system. tips on mapping domain models to design. Discussions not on the technology but more on how to BEST use the technology in design (real world "complex" examples would be great).

• visualising piano performance evaluation

  - by Dolphin

  I need to develop a performance evaluator for piano playing. Based on a midi generated from sheet music, I need to evaluate the midi of the actual playing (midi keyboard). I'm planning to evaluate the playing based on note pitch, duration and loudness. The evaluation is I suppose a comparison of the notes of the sheet music and playing in midi. But I have no idea how I can visualise (i.e. show where the person have gone wrong) this evaluation process. i.e. maybe show both the notation and highlight which note has gone wrong. But how can I show any of this in some graphical form? Or more precisely on a stave (a music score) itself. I have note details (pitch, duration) and score details (key and time signature) stored in a table, and I'm using Java. But I have no clue as in how I can put all this into graphical form. Any insight is most gratefully appreciated. Advance thanks

• Android: Why my user Interface does not get drawn when I Inflate the resource layout file?

  - by Einiosaurus

  First of all, I'm a newbie on Android programming, so please be detailed in your answers. I have a layout main.xml file with format similar to <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android = "http://schemas.android.com/apk/res/android" android:orientation = "vertical" android:layout_width = "fill_parent" android:layout_height = "fill_parent"> <LinearLayout xmlns:android = "http://schemas.android.com/apk/res/android" android:orientation = "horizontal"   android:layout_width = "fill_parent" android:layout_height = "fill_parent"> <EditText android:id="@+id/a" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <TextView android:id="@+id/xSquared" android:layout_width = "fill_parent" android:layout_height = "wrap_content" android:text = "@string/equationPart1" /> </LinearLayout> <LinearLayout ... </LinearLayout> </LinearLayout> In my Java source file, I inflate the UI using command: setContentView(R.layout.main); public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } However, when I run the emulator, the UI does not show up like what I expect. Instead, it just display a simple EditText text box. I wonder what is going wrong. Is it because I put a layout inside another layout? I don't think there is any problem with that right?

• SpeechRecognizer causes ANR... I need help with Android speech API.

  - by Dondo Chaka

  I'm trying to use Android's speech recognition package to record user speech and translate it to text. Unfortunately, when I attempt initiate listening, I get an ANR error that doesn't point to anything specific. As the SpeechRecognizer API indicates, a RuntimeException is thrown if you attempt to call it from the main thread. This would make me wonder if the processing was just too demanding... but I know that other applications use the Android API for this purpose and it is typically pretty snappy. java.lang.RuntimeException: SpeechRecognizer should be used only from the application's main thread Here is a (trimmed) sample of the code I'm trying to call from my service. Is this the proper approach? Thanks for taking the time to help. This has been a hurdle I haven't been able to get over yet. Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM); intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, "com.domain.app"); SpeechRecognizer recognizer = SpeechRecognizer .createSpeechRecognizer(this.getApplicationContext()); RecognitionListener listener = new RecognitionListener() { @Override public void onResults(Bundle results) { ArrayList<String> voiceResults = results .getStringArrayList(RecognizerIntent.EXTRA_RESULTS); if (voiceResults == null) { Log.e(getString(R.string.log_label), "No voice results"); } else { Log.d(getString(R.string.log_label), "Printing matches: "); for (String match : voiceResults) { Log.d(getString(R.string.log_label), match); } } } @Override public void onReadyForSpeech(Bundle params) { Log.d(getString(R.string.log_label), "Ready for speech"); } @Override public void onError(int error) { Log.d(getString(R.string.log_label), "Error listening for speech: " + error); } @Override public void onBeginningOfSpeech() { Log.d(getString(R.string.log_label), "Speech starting"); } }; recognizer.setRecognitionListener(listener); recognizer.startListening(intent);

• architecture and tools for a remote control application?

  - by slothbear

  I'm working on the design of a remote control application. From my iPhone or a web browser, I'll send a few commands. Soon my home computer will perform the commands and send back results. I know there are remote desktop apps, but I want something programmable, something simpler, and something that I wrote. My current direction is to use Amazon Simple Queue Service (SQS) as the message bus. The iPhone places some messages in a queue. My local Java/JRuby program notices the messages on the queue, performs the work and sends back status via a different queue. This will be a very low-volume application. At $1.00 for a million requests (plus a handful of data transfer charges), Amazon SQS looks a lot more affordable than having my own server of any type. And super reliable, that's important for me too. Are there better/standard toolkits or architectures for this kind of remote control? Cost is not a big issue, but I prefer the tons I learn by doing it myself. I'm moderately concerned about security, but doubt it will be a problem. The list of commands recognized will be very short, and only recognized in specific contexts. No "erase hard drive" stuff. update: I'll probably distribute these programs to some other people who want the same function, but who don't have Amazon SQS accounts. For now, they'll use anonymous access to my queues, with random 80-character queue names.

• FOSS ASP.Net Session Replication Solution?

  - by jsight

  I've been searching (with little success) for a free/opensource session clustering and replication solution for asp.net. I've run across the usual suspects (indexus sharedcache, memcached), however, each has some limitations. Indexus - Very immature, stubbed session interface implementation. Its otherwise a great caching solution, though. Memcached - Little replication/failover support without going to a db backend. Several SF.Net projects - All aborted in the early stages... nothing that appears to have any traction, and one which seems to have gone all commercial. Microsoft Velocity - Not OSS, but seems nice. Unfortunately, I didn't see where CTP1 supported failover, and there is no clear roadmap for this one. I fear that this one could fall off into the ether like many other MS dev projects. I am fairly used to the Java world where it is kind of taken for granted that many solutions to problems such as this will be available from the FOSS world. Are there any suitable alternatives available on the .Net world?

• Where can a self-teacher learn general good programming habits and conventions?

  - by lucid

  A few mistakes and general childishness in early adulthood have left me in a situation where I work a menial job, with no possibility (in the near future) of attending school. I aspire to one day work in the programming field (gaming specifically), after proving myself on the indie end of things. I've gotten very confident in C++, java, and python, and I find I'm able to solve any problem I want either from previous experience, or from scouring the web for help. The solutions work, and with each attempt they become more readable, maintainable, and extensible. But this is because I'm learning from mistakes and bad programming and design habits I feel I might have avoided with actual schooling. General tips like: "if it's hard to read or getting long, or you're writing it twice, it should be in one or more functions." or "design all your classes before you start coding, so you don't have to rewrite classes later when you discover an unforeseen dependency" Is there a good book or website for learning general good programming practices and design habits? Also, naming and format conventions. I realize sometimes development houses have their own conventions, but things like "Classes in python usually have the first letter of each word capitalized". I'd like to be able to show some source code to a potential employer, and be prepared when for what's expected on a team. Is there some central database of naming and formatting conventions somewhere? Also, feel free to give any thoughts on whether or not the self-teach, garner some indie sales, use them as your resume' route is realistic
