• Retrofit WebForms with ASP.NET MVC - NoVa Code Camp 2010.2 Demo

  - by Soe Tun

  Thank you to everyone who attended my Retrofit WebForms with ASP.NET MVC session at NoVa Code 2010.2. It was a fun event for me and I hope you had a great time and learned something from it. I wish I had more time to go over some more important topics in more detail. I *promise* I will be writing blog post series about it since I'll have some vacation time during the December holidays to cover some topics that I didn't get to cover in detail.   Please note that the ".bak" file included in the zip file is a SQL Server Database backup file. You have to restore it on your Database server to run it with the source code demo.   Please feel free to ask me about the demo project through Twitter or from this blog post. I'll be glad to help you out. If you want me to give this presentation at your .NET User Group, please let me know and I'll be honored to speak there also.   Again, thank you all and have a great holiday season. Here is the download link to my Demo project Zip file with the PowerPoint presentation in it. Please let me know if the link doesn't work.

• 14.04.1 LTS 64 bit from USB does not see my windows 7 when I go to install it

  - by W J

  I suppose this is as much a question as a heads up/warning 14.04.1 LTS only gave me the option of writing over everything on one of my windows 7 machines. If I'd pushed the wrong button and continued I would have lost some mighty important items. On a similar windows laptop I succesfully installed 14.04.1 LTS 32 bit alongside windows 7 rather easily ( and I dig it!), there was a prompt in that case that let me select to install it alongside my windows OS.Yikes, not in this case. This laptop was formatted NTFS, the Ubuntu usb pendrive I formatted fat32. could be a clue? It looks like there is an advanced install ubuntu, but I am not that advanced. I may try to use windows diskformat (What fdisk is gone?) to make a partition, then see if the ubuntu on my usb stick "sees" my windows. If anybody has a better plan let me know. Mahalo AHA!? p.s. its a SSD harddrive, perhaps thats the crux?

• Bundling in visual studio 2012 for web optimization

  - by Jalpesh P. Vadgama

  I have been writing a series of posts about Visual Studio 2012 features. This series describes what are the new features in the Visual Studio 2012. This post will also be part of Visual Studio 2012 feature series. As we know now days web applications or site are providing more and more features and due to that we have include lots of JavaScript and CSS files in our web application.So once we load site then we will have all the JavaScript  js files and CSS files loaded in the browsers and If you have lots of JavaScript files then its consumes lots of time when browser request them. Following images show the same situation over there.   Here you can see total 25 files loaded into the system and it's almost more than 1MB of total size. As we need to have our web application of site very responsive and need to have high performance application/site, this will be a performance bottleneck to our site. In situation like this, the bundling feature of Visual Studio 2012 and ASP.NET 4.5 comes very handy. With the help of this feature we do optimization there and we can increase performance of our application. To enable this feature in Visual Studio 2012 we just made debug=”false” in web.config of our application like following. Now once you enable this feature and run this application in the browser to see your traffic it will have less items like following. As you can see in the above image there are only 8 items. So after enabling bundling it will automatically convert all js and css files into the one request. Isn’t that cool feature? This feature will surely going to have great impact on performance. Hope you like it. Stay tuned for more.. Till then happy programming!!

• Data classes: getters and setters or different method design

  - by Frog

  I've been trying to design an interface for a data class I'm writing. This class stores styles for characters, for example whether the character is bold, italic or underlined. But also the font-size and the font-family. So it has different types of member variables. The easiest way to implement this would be to add getters and setters for every member variable, but this just feels wrong to me. It feels way more logical (and more OOP) to call style.format(BOLD, true) instead of style.setBold(true). So to use logical methods insteads of getters/setters. But I am facing two problems while implementing these methods: I would need a big switch statement with all member variables, since you can't access a variable by the contents of a string in C++. Moreover, you can't overload by return type, which means you can't write one getter like style.getFormatting(BOLD) (I know there are some tricks to do this, but these don't allow for parameters, which I would obviously need). However, if I would implement getters and setters, there are also issues. I would have to duplicate quite some code because styles can also have a parent styles, which means the getters have to look not only at the member variables of this style, but also at the variables of the parent styles. Because I wasn't able to figure out how to do this, I decided to ask a question a couple of weeks ago. See Object Oriented Programming: getters/setters or logical names. But in that question I didn't stress it would be just a data object and that I'm not making a text rendering engine, which was the reason one of the people that answered suggested I ask another question while making that clear (because his solution, the decorator pattern, isn't suitable for my problem). So please note that I'm not creating my own text rendering engine, I just use these classes to store data. Because I still haven't been able to find a solution to this problem I'd like to ask this question again: how would you design a styles class like this? And why would you do that? Thanks on forehand!

• design for supporting entities with images

  - by brainydexter

  I have multiple entities like Hotels, Destination Cities etc which can contain images. The way I have my system setup right now is, I think of all the images belonging to this universal set (a table in the DB contains filePaths to all the images). When I have to add an image to an entity, I see if the entity exists in this universal set of images. If it exists, attach the reference to this image, else create a new image. E.g.: class ImageEntityHibernateDAO { public void addImageToEntity(IContainImage entity, String filePath, String title, String altText) { ImageEntity image = this.getImage(filePath); if (image == null) image = new ImageEntity(filePath, title, altText); getSession().beginTransaction(); entity.getImages().add(image); getSession().getTransaction().commit(); } } My question is: Earlier I had to write this code for each entity (and each entity would have a Set collection). So, instead of re-writing the same code, I created the following interface: public interface IContainImage { Set<ImageEntity> getImages(); } Entities which have image collections also implements IContainImage interface. Now, for any entity that needs to support adding Image functionality, all I have to invoke from the DAO looks something like this: // in DestinationDAO::addImageToDestination { imageDao.addImageToEntity(destination, imageFileName, imageTitle, imageAltText); // in HotelDAO::addImageToHotel { imageDao.addImageToEntity(hotel, imageFileName, imageTitle, imageAltText); It'd be great help if someone can provide me some critique on this design ? Are there any serious flaws that I'm not seeing right away ?

• Are there any real-world cases for C++ without exceptions?

  - by Martin

  In When to use C over C++, and C++ over C? there is a statement wrt. to code size / C++ exceptions: Jerry answers (among other points): (...) it tends to be more difficult to produce truly tiny executables with C++. For really small systems, you're rarely writing a lot of code anyway, and the extra (...) to which I asked why that would be, to which Jerry responded: the main thing is that C++ includes exception handling, which (at least usually) adds some minimum to the executable size. Most compilers will let you disable exception handling, but when you do the result isn't quite C++ anymore. (...) which I do not really doubt on a technical real world level. Therefore I'm interested (purely out of curiosity) to hear from real world examples where a project chose C++ as a language and then chose to disable exceptions. (Not just merely "not use" exceptions in user code, but disable them in the compiler, so that you can't throw or catch exceptions.) Why does a project chose to do so (still using C++ and not C, but no exceptions) - what are/were the (technical) reasons? Addendum: For those wishing to elaborate on their answers, it would be nice to detail how the implications of no-exceptions are handled: STL collections (vector, ...) do not work properly (allocation failure cannot be reported) new can't throw Constructors cannot fail

• Where to look for challenging jobs with a relaxed atmosphere?

  - by RBTree

  I'm a dev at one of the big-name tech companies. I like the job for many reasons: I do interesting work on a cool product I solve challenging problems and use a lot of high-level skills (quantitative, creative, writing, presenting) It pays well The problem is that I feel I need a more relaxed atmosphere (shorter hours, less performance pressure, and more flexibility), in order to free up time for other pursuits and reduce stress. The ideal would be a job that's around 30-35 hours a week, where there is flexibility to work more or less in a given week. Can anyone suggest where to look for a job like this, where I wouldn't have to sacrifice too much on the above points? (Obviously I would have to sacrifice pay.) My employer does not generally offer part-time employment. The closest thing I can think of is when I did summer internships at my university's CS department. The work was very intellectually challenging, but if I needed to go home a couple hours early or get flexibility on a due date, nobody batted an eyelash. However, I'd like to find out if there are alternatives to academia since from what I've seen the pay there is a gigantic drop from what I'm currently making. I've done freelance development before, but I do like that as an employee of a large company I have a lot of things taken care of for me (e.g. benefits and guaranteed stable employment).

• What are the options for retraining formally as a software engineer?

  - by Matt Harrison

  I'm a self-taught programmer. I have a good undergraduate degree in Architecture (building, not software). I was always a science/maths kid and got consistency good grades in these subjects. However I became indecisive at undergraduate level and switched between Physics, Chemistry, Art and finally stuck with Architecture mainly out of the desperate need to finish any degree. As soon as I graduated, I ditched architecture and started writing code again professionally. I've been a programmer now for 3 years and I've progressed very quickly. I'm ambitious and I want to work for the top companies in this field at some point and I've realised I need a Computer Science education to be taken seriously (based on job ads for the big tech firms). I've applied for a few MSc programs in Computer Science but they've all rejected me because of my BA. It's just not an option for me to quit my job and go back and do another 3 year undergraduate degree in CS. I know I can study at this level because I've read most of the books on the reading lists for CS courses in the UK that I can find and I have this knowledge now, it's just I can't prove it on an application form. What options are available to me?

• How do I parse a header with two different version [ID3] avoiding code duplication?

  - by user66141

  I really hope you can give me some interesting viewpoints for my situation, because I am not satisfied with my current approach. I am writing an MP3 parser, starting with an ID3v2 parser. Right now I`m working on the extended header parsing, my issue is that the optional header is defined differently in version 2.3 and 2.4 of the tag. The 2.3 version optional header is defined as follows: struct ID3_3_EXTENDED_HEADER{ DWORD dwExtHeaderSize; //Extended header size (either 6 or 8 bytes , excluded) WORD wExtFlags; //Extended header flags DWORD dwSizeOfPadding; //Size of padding (size of the tag excluding the frames and headers) }; While the 2.4 version is defined : struct ID3_4_EXTENDED_HEADER{ DWORD dwExtHeaderSize; //Extended header size (synchsafe int) BYTE bNumberOfFlagBytes; //Number of flag bytes BYTE bFlags; //Flags }; How could I parse the header while minimizing code duplication? Using two different functions to parse each version sounds less great, using a single function with a different flow for each occasion is similar, any good practices for this kind of issues ? Any tips for avoiding code duplication? Any help would be appreciated.

• Tips about how to spread Object Oriented practices

  - by Augusto

  I work for a medium company that has around 250 developers. Unfortunately, lots of them are stuck in a procedural way of thinking and some teams constantly deliver big Transactional Script applications, when in fact the application contains rich logic. They also fail to manage the design dependencies, and end up with services which depend on another large number of services (a clean example of Big Ball of Mud). My question is: Can you suggest how to spread this type of knowledge? I know that the surface of the problem is that these applications have a poor architecture and design. Another issue is that there are some developers who are against writing any kind of test. A few things I'm doing to change this (but I'm either failing or the change is too small are) Running presentations about design principles (SOLID, clean code, etc). Workshops about TDD and BDD. Coaching teams (this includes using sonar, findbugs, jdepend and other tools). IDE & Refactoring talks. A few things I'm thinking to do in the future (but I'm concern that they might not be good) Form a team of OO evangelists, who disseminate an OO way of thinking in differet teams (these people would need to change teams every few months). Running design review sessions, to criticise the design and suggest improvements (even if the improvements are not done because of time constraints, I think this might be useful) . Something I found with the teams I coach, is that as soon as I leave them, they revert back to the old practices. I know I don't spend a lot of time with them, usually just one month. So whatever I'm doing, it doesn't stick. I'm sorry this question is spattered with frustration, but the alterative to write this was to hit my head on the wall until I pass out.

• Sharing My Thoughts on Space Flight

  - by Grant Fritchey

  This went out in the DBA newsletter from Red Gate, but I enjoyed writing it so much, I thought I'd share it to a wider audience: I grew up watching the US space program. I watched men walk on the moon for the first time in 1969, when I was only six years old. From that moment on, I dreamed of going into space. I studied aeronautics and tried to get into the Air Force Academy, all in preparation for my long career as an astronaut. Clearly, that didn't quite work out for me. But it sure could for you. At Red Gate, we're running a new contest: DBA in Space. The prize is a sub-orbital flight. When I first got word of this contest, my immediate response was, "And you need me to go right away and do a test flight? Excellent!" No, no test flight needed, plus I was pretty low on the list of volunteers. "That's OK, I'll just enter." Then I was told that, as a Red Gate employee, I couldn't win. My next response was, "I quit".eventually, I was talked down off the ledge, and agreed to help make this special for some other DBA. Many (most?) of us are science fiction fans, either the soft science of Star Trek and Star Wars, or the hard science of Niven and Pournelle, or Allen Steele. We watched the Shuttles go up and land. We've been dreaming of our own trips into orbit and our vacation-home on the Moon for a long, long time. All that might not arrive on schedule, but you've got a shot at breaking clear of the atmosphere. The first stage is a video quiz, starring Brad McGehee, and it's live at www.DBAinSpace.com now. Go for it. Good luck and God speed!

• I'm applying for a position at a startup. To whom should I address my cover letter?

  - by sapphiremirage

  One of the co-founders answered questions about the company when the job was posted, but I feel like I shouldn't assume that he's the one who is in charge of hiring. Since it's relatively new and has a lot of name overlap with other things already on the web, it's hard to find any information about the company online, much less the name of their hiring manager. I'm not even certain that they do have a hiring manager, since I seem to remember that they are just an 8 person team. I've heard that "To whom it may concern" is tacky, and normally I would say something along the lines of "Dear Head of Human Resources", but that clearly doesn't work in this case. Any idea what my salutation should be? Later Edits: Final Version: To Joe Programmer and/or the AwesomeStartup.com hiring team, (+ a few words in first paragraph explaining why I am addressing Joe Programmer) I've already sent the email, so nothing you say here will save me. However, feel free to comment on my decision if you think your words be useful to future generations. Old Version (left here because some people responded to it): To the hiring manager for internships at Awesomestartup.com, Additionally, because so many people made comments about the content of my letter: I did spent several hours writing the cover letter itself and making sure that it was awesome. After spending such a long time working on the important part, I asked this question because I wanted to make sure that it wouldn't get passed over by some human who was having a bad day and decided that my salutation was inappropriate. Not likely when the most likely reader of that email is a programmer type, I know, but I figured that it wouldn't hurt not to be sloppy.

• How to get started in coding for JBoss

  - by Mister IT Guru

  I have an idea on how to revamp our internal application, after having accessed the needs of the users, addressing thier current issues, and the like. But I am not a coder. My last application I wrote was in college, in C, (java wasn't invented-ish!) and it was a booking system, with the option to add on other modules, blah blah. I got an A, but I became a system administrator instead, more intrested in designing and maintainend networks and infrastructure, but with the advent of virtualisation, and linux management tools such as puppet I can now manage infrastructure in my sleep! Now I want to write code - to put on my infastructure, and I want to build .... a booking system! This is just to get experience, but I am at a loss as to where to start. Setting up the environment, will take me about a day. Writing the spec, even how I want it to work, I already know, but as for actually coding in a decent manner, I can only guess. If anyone can recommend a book, website, blog, twitter person to follow, or just advice on how to build a kick butt basic jboss app, then please, "I AM READY TO LEARN" :)

• JRuby and JVM Languages at JavaOne!

  - by Yolande Poirier

  "My goal with my talks at JavaOne is to teach what is happening at the JVM level and below so people understand better where we are going" explains Charles Nutter, Jruby project lead. In this interview, Charles shared the JRuby features he presented at the JVM Language Summit. They include foreign function interface (FFI), IO layer, character transcoding, regular expressions, compilers, coroutines, and more.  At JavaOne, he will be presenting:  Going Native: Bringing FFI to the JVM The Java Native Runtime (JNR) is a high-speed foreign function interface (FFI) for calling native code from Java without ever writing a line of C. Based on the success of JNR, JDK Enhancement Proposal (JEP) 191 will bring FFI to OpenJDK as an internal API.  The Emerging Languages Bowl: The Big League Challenge In this panel discussion, these emerging languages are portrayed by their respective champions, who explain how they may help your everyday life as a Java developer. Script Bowl 2014: The Battle Rages On In this contest, languages that run on the JVM, represented by their respective language experts, battle for most popular language status by showing off their new features. Audience members will also vote on a language that should not return in 2015. Returning from 2013 are language gurus representing Clojure, Groovy, JRuby, and Scala.

• Object oriented wrapper around a dll

  - by Tom Davies

  So, I'm writing a C# managed wrapper around a native dll. The dll contains several hundred functions. In most cases, the first argument to each function is an opaque handle to a type internal to the dll. So, an obvious starting point for defining some classes in the wrapper would be to define classes corresponding to each of these opaque types, with each instance holding and managing the opaque handle (passed to its constructor) Things are a little awkward when dealing with callbacks from the dll. Naturally, the callback handlers in my wrapper have to be static, but the callbacks arguments invariable contain an opaque handle. In order to get from the static callback back to an object instance, I've created a static dictionary in each class, associating handles with class instances. In the constructor of each class, an entry is put into the dictionary, and this entry is then removed in the Destructors. When I receive a callback, I can then consult the dictionary to retrieve the class instance corresponding to the opaque reference. Are there any obvious flaws to this? Something that seems to be a problem is that the existence static dictionary means that the garbage collector will not act on my class instances that are otherwise unreachable. As they are never garbage collected, they never get removed from the dictionary, so the dictionary grows. It seems I might have to manually dispose of my objects, which is something absolutely would like to avoid. Can anyone suggest a good design that allows me to avoid having to do this?

• Best Architecture for ASP.NET WebForms Application

  - by stack man

  I have written an ASP.NET WebForms portal for a client. The project has kind of evolved rather than being properly planned and structured from the beginning. Consequently, all the code is mashed together within the same project and without any layers. The client is now happy with the functionality, so I would like to refactor the code such that I will be confident about releasing the project. As there seems to be many differing ways to design the architecture, I would like some opinions about the best approach to take. FUNCTIONALITY The portal allows administrators to configure HTML templates. Other associated "partners" will be able to display these templates by adding IFrame code to their site. Within these templates, customers can register and purchase products. An API has been implemented using WCF allowing external companies to interface with the system also. An Admin section allows Administrators to configure various functionality and view reports for each partner. The system sends out invoices and email notifications to customers. CURRENT ARCHITECTURE It is currently using EF4 to read/write to the database. The EF objects are used directly within the aspx files. This has facilitated rapid development while I have been writing the site but it is probably unacceptable to keep it like that as it is tightly coupling the db with the UI. Specific business logic has been added to partial classes of the EF objects. QUESTIONS The goal of refactoring will be to make the site scalable, easily maintainable and secure. 1) What kind of architecture would be best for this? Please describe what should be in each layer, whether I should use DTO's / POCO / Active Record pattern etc. 2) Is there a robust way to auto-generate DTO's / BOs so that any future enhancements will be simple to implement despite the extra layers? 3) Would it be beneficial to convert the project from WebForms to MVC?

• Deciding on a company-wide javascript strategy [on hold]

  - by drogon

  Our company is moving most of its software from thick-client winforms apps to web apps. We are using asp.net mvc on the server side. Most of the developers are brand new to the web and need to become efficient and knowledgeable at writing client-side web code (javascript). We are deciding on a number of things and would appreciate feedback on the following: Angular.js or Backbone.js? Backbone (w/ Underscore) is certainly more light weight, but requires more custom development. Angular seems to be a full-fledged framework, but would require everyone to embrace it and probably a longer learning curve(??). (Note: I know nothing about Angular at this point) Require.js or script includes w/ MVC bundleconfig? Require.js makes development "feel like" c# (importing namespaces). But, integrating the build/minification process can be a pain (especially the configuration). Bundling via mvc requires developers to worry more about which scripts to include but has less overall development friction. Typescript vs Javascript Regardless of frameworks, our developers are going to need to learn the basics. Typescript is more like c# and MAY be easier for c# developers to understand. However, learning TypeScript before javascript may hinder their mastery of javascript at the expense of efficiency.

• Http handler for classic ASP application for introducing a layer between client and server

  - by JPReddy

  I've a huge classic ASP application where in thousands of users manage their company/business data. Currently this is not multi-user so that application users can create users and authorize them to access certain areas in the system. I'm thinking of writing a handler which will act as middle man between client and server and go through every request and find out who the user is and whether he is authorized to access the data he is trying to. For the moment ignore about the part how I'm going to check the authorization and all that stuff. Just want to know whether I can implement a ASP.net handler and use it as middle man for the requests coming for a asp website? I just want to read the url and see what is the page user is trying to access and what are the parameters he is passing in the url the posted data. Is this possible? I read that Asp.net handler cannot be used with asp website and I need to use isapi filter or extensions for that and that can be developed only c/c++. Can anybody through some light on this and guide me whether I'm in the right direction or not?

• Fiction that includes BASIC programs [closed]

  - by Clinton Blackmore

  Back in what must've been the mid-80s, when every microcomputer included BASIC and Choose Your Own Adventure Books were really popular, there were some novels that had BASIC programs listed in the text, for you to type in and further enjoy. For example, as I recall, in one of these books, the adventurers were infiltrating an undersea base (and eventually wiped the bad guy's data storage [I do believe it was a hard drive, even though they were uncommon then]). One of the programs involved a game were you piloted a submarine and had to avoid or shoot sharks. The code was in BASIC; minor changes (such as 'CLS' - 'HOME') had to be made for your specific computer, and it used good old 40-column text-mode to display the action. IIRC, the plot never depended upon the programs. My question is, does anyone else recall these sorts of books? Do you know any titles that I could look for, or of any online? I am toying with the idea of writing a story like this (no, not in BASIC!), and would really like to see how it was done, back in the day.

• How do I debug an overheating problem?

  - by Tab

  Hello guys. I have a problem with my Laptop (Dell Inspiron 1564 Core i5 4GB Ram VGA ATI Mobility Radeon HD 4300 running Ubuntu 10.10 32bit). It shuts down abruptly without even a lag in the application I am working with before shutdown. I think it's overheating problem. Actually the laptop is hot all the time when I am running Ubuntu. When I switch back to windows, even with intense load it won't shutdown or show any problem as long as I keep proper ventilation (when the air openings are blocked it does the same). Actually on Ubuntu i don't usually do things that need much CPU power, usually surfing internet, coding web pages and sometimes playing with python and ruby. I am not enabling desktop effects so no GPU load except the normal GNOME gui. Now as I am writing the Processor load in the panel monitor applet is 0%, Memory 11% by programs, 22% by cache. And i have CPU Frequency monitor for each of the 4 cores set to 1.20 Ghz (the lowest possible value, i am not sure if this applet does really limit CPU usage). Running sensors in terminal gave me temp1: +26.8°C (crit = +100.0°C) temp2: +0.0°C (crit = +100.0°C) hddtemp /dev/sda at the terminal gave me /dev/sda: WDC WD3200BEVT-75ZCT2: 46°C All that fine but the laptop is Really hot i can feel it in the keyboard, mouse pad is painful to touch, and the fan is always spinning. I am also placing 2 small fans running on USB under the laptop right now and the laptop is lifted over the fans so it's well ventilated. When I am running windows it doesn't get that hot except when there is a really big load on the CPU and this is keeping me away from using Linux for everyday tasks. Actually I don't care much for speed as I can deal with low speed it's not going to shutdown abruptly. So please if you can help me and tell me what are the possible causes, where should I start ?

• Lead Programmer definition clarification

  - by Junaid

  I am working on PHP and MySQL based web application for more than 5 years now. I started my career from Intern - Jr Developer - Software Developer - Sr. Software Engineer [Team Lead] that's what I am nowadays. I was looking at the link at Wikipedia regarding who is a lead programmer. The link states the following: A lead programmer is a software engineer in charge of one or more software projects. Alternative titles include Development Lead, Technical Lead, Senior Software Engineer, Software Design Engineer Lead (SDE Lead), Software Manager, or Senior Applications Developer. When primarily contributing in a high-level enterprise software design role, the title Software Architect (or similar) is often used. All of these titles can have different meanings depending on the context. My current job responsibilities are more or less like a Development Lead and to some extent near Software Architect because I usually design the core structure of new products and managing 2-3 project simultaneously and in the meantime involved in assisting other teams regarding the structural design of their projects, I am usually on call with clients along with project managers, I code most of the time when my team stuck somewhere / workload / integrating some third party API and etc. Primary reason of this writing is to know if I qualify for a Development Lead Title? in accordance with my above mentioned job descriptions?

• Best practice for combining a Java Applet/ Android interface?

  - by Pearsonartphoto

  I'm working on an online game, which I am seriously considering writing a Java Applet for it. The game is not overly complex on the features. I'm considering at some point having at least 3 versions of the game, which include a Java stand alone, applet, and Android game. I know from Design Patterns that the best way to use differing things like buttons and the like is to use a Bridge interface, where I have a common template for the common buttons. However, I'm having a bit of difficulty understanding what to do about the following. I know that Android programs use an Activity structure, which I am well familiar with, and that Applets extend the Applet interface, which I am not as familiar with. I also know that a stand alone java program uses basically a main() function, which doesn't have much structure. I'm convinced that there should be a way to design a common design pattern between the two, but somehow I'm missing what that is exactly. What can I do to make the different frameworks work with as much common code as possible?

Open-XDX uses code-free techniques in combination with CAM templates and visual drag and drop to rapidly design your XML exchange. Then Open-XDX will automatically generate all the SQL for you, read the database data, generate and populate the valid output XML, and filter with parameters. To complete the processing solution Open-XDX works with web services and JDBC database connections as a callable module that can be deployed plug and play with your middleware stack, all with just a few lines of Java code (about 5 actually). You can build either Query/Response or Publish/Subscribe services from existing data stores to XML literally in minutes. To see a demonstration of using Open-XDX, a MySQL data store and integrating with Oracle Web Logic server please see this short few minutes video - http://youtube.com/user/TheCameditor There is also a Quick Guide available that provides more technical insights along with a sample pack download of templates and SQL that you can try for yourself. Head on over to our project resource site to learn more, download the latest CAM Editor and see links to all the resources and materials. We look forward to seeing how the developer community is able to jump start information sharing initiatives using this new innovative approach.

• What's wrong with cplusplus.com?

  - by Kerrek SB

  This is perhaps not a perfectly suitable forum for this question, but let me give it a shot, at the risk of being moved away. There are several references for the C++ standard library, including the invaluable ISO standard, MSDN, IBM, cppreference, and cplusplus. Personally, when writing C++ I need a reference that has quick random access, short load times and usage examples, and I've been finding cplusplus.com pretty useful. However, I've been hearing negative opinions about that website frequently here on SO, so I would like to get specific: What are the errors, misconceptions or bad pieces of advice given by cplusplus.com? What are the risks of using it to make coding decisions? Let me add this point: I want to be able to answer questions here on SO with accurate quotes of the standard, and thus I would like to post immediately-usable links, and cplusplus.com would have been my choice site were it not for this issue. Update: There have been many great responses, and I have seriously changed my view on cplusplus.com. I'd like to list a few choice results here; feel free to suggest more (and keep posting answers). As of June 29, 2011: Incorrect description of some algorithms (e.g. remove). Information about the behaviour of functions is sometimes incorrect (atoi), fails to mention special cases (strncpy), or omits vital information (iterator invalidation). Examples contain deprecated code (#include style). Inexact terminology is doing a disservice to learners and the general community ("STL", "compiler" vs "toolchain"). Incorrect and misleading description of the typeid keyword.

• Challenging Job after Graduate Studies

  - by sriram

  I worked with an M.N.C developing web applications in Java/J2EE related technologies(includes JSF,struts,hibernate etc.) now I quit my job to pursue Graduate Studies in the U.S.A. So I am a student in the middle of my Graduate studies. I had enough of developing mere CRUD applications in J2EE now I want to work in something exciting. The problem is I can't say what exactly but I can give you an examples. Say developing new JDK libraries or writing a kernel for some O.S. or something like that. So I have five questions here. Is it true that people in R & D often use C++ because of higher performance in that case should I consider switching my platform to C/C++? How should I use my time I have one year to graduate to prepare myself for Jobs Interviews for such positions? (e.g. Reading books on Algorithms etc.) How do I know about these jobs and how do I apply to those Jobs? Is it the right time for me to think about Jobs? Am I over ambitious because I am not in a Ivy League, just a normal school? (My GPA is not so high unfortunately).
