  • IASA ITARC &ndash; Denver May 6th

    - by Jeff Certain
    The Denver chapter of the International Association of Software Architects (IASA) is holding an IT Architect Regional Conference (ITARC) in Denver on May 6th. The speaker list for this conference is amazing. Paul Rayner, Dave McComb, Randy Kahle, Peter Provost, Randy Stafford, George Fairbanks – all great speakers, and from Colorado. Brandon Satrom (who also happens to be the president of the IASA Austin chapter) will also be speaking, as will some other heavy hitters (for example, Ted Farrell, Chief Architect and Senior VP of Oracle). This is an amazing line-up, and the conference is quite reasonably priced ($150 for IASA members until April 10th, including a catered lunch). I also have the privilege of being a presenter at this conference. If you’ve ever heard any of the previously named speakers, you know that they set the bar quite high. Sounds like I’m going to have to step up my game. What I get to talk about is really cool stuff. The company I work for – Colorado CustomWare – brought me on board nearly two years ago. To say there was some technical debt is somewhat… understated. Equally understated would be that management is committed to doing the right thing. Over the past two years, we’ve done significant architectural refactoring – including an effort that took the entire team offline for most of a month. We’ve reduced the application size by 50% without losing functionality. As you can imagine, this has reduced the complexity of the application, making development faster and less prone to bugs. We’ve made many other changes – moving to an agile process, training developers, moving towards a more OO architecture. The changes we’ve made reveal, in some ways, just how far afield we were.. and there are still more changes to be made. Amazingly enough, our leadership team is eager for me to share these experiences with other architects. I’m really looking forward to being able to do so.

  • How relevant is UTF-7 when it comes to parsing emails?

    - by J. Pablo Fernández
    I recently implemented incoming emails for an application and boy, did I open the gates of hell? Since then every other day an email arrives that makes the app fail in a different way. One of those things is emails encoded as UTF-7. Most emails come as ASCII, some of the Latin encodings, or thankfully, UTF-8. Hotmail error messages (like email address doesn't exist or quota exceeded) seem to come as UTF-7. Unfortunately, UTF-7 is not an encoding Ruby understands: > "hello world".encode("utf-8", "utf-7") Encoding::ConverterNotFoundError: code converter not found (UTF-7 to UTF-8) > Encoding::UTF_7 => #<Encoding:UTF-7 (dummy)> My application doesn't crash, it actually handles the email quite well, but it does send me a notification about the potential error. I spent some time googling and I can't find anyone that implemented the conversion, at least not as a Ruby 1.9.3 Encoding::Converter. So, my question is, since I never got an email with actual content, from an actual person, in UTF-7, how relevant is that encoding? can I safely ignore it?

  • How to Hibernate from .NET Apps and How to enable Hibernate in Windows XP

    The usage of Computer desktop or laptop is increased all around the world phenomenally. This link gives you the picture on how power consumption is for various devices we use daily. to reduce the power consumption Hibernate is one of the best way provided by default in Windows Vista or Windows 7. Hibernate feature enables you to close the machine without closing your applications, that means the applications will be restored as they were once we restart the machine. Hibernate feature is not enabled in Windows XP by default. I’ve seen many people that they run (do not switch off) the machines months and months as they do not want to close the windows or applications running in Windows XP. below are the steps to enable Hibernate in Windows XP. Right click on Desktop. Click on properties. Go to screen save tab. Click on power button Select Hibernate tab Check the checkbox “Enabled Hibernate” Apply the settings. Now when you try to shutdown, “Shut down windows” dialog shows “Hibernate” options. Now you can safely close the machine without closing your applications or windows as they will be restored once you on the machine. </SPAN? Some time you might want to provide this future programmatically for the applications you develop for windows. Generally you might want to provide this option in windows applications where process needs huge time. Download managers are the one of the best example. below is the code to do a Hibernate from the .NET code. using System.Windows.Forms;namespace CodeKicks.WinApp.Machine{ public static class MyMachineHelper { public static void DoHibernate() { //Application.SetSuspendState(PowerState.Suspend, true, false); Application.SetSuspendState(PowerState.Hibernate, true, false); } }} span.fullpost {display:none;}

  • SQL SERVER – Load Generator – Free Tool From CodePlex

    - by pinaldave
    One of the most common questions I receive is if there any tool available to generate load on SQL Server. Absolutely there is a fabulous free tool available to generate load on SQL Server on Codeplex. This tool was released in 2008 but it is still extremely relevant to generate the load on SQL Server as well works fabulously. CodePlex is a project initiated by Microsoft for hosting open source softwares. The best part of this SQL Server Load Generator is that users can run multiple simultaneous queries again SQL Server using different login account and different application name. The interface of the tool is extremely easy to use and very intuitive as well. One of the things which I felt needed improvement was a default configuration. As every single time when I was adding a query the default settings were showing up and I had to manually change that. However, when I went to Menu >> Tools >>Options I was really happy as it has options to change every single default which is available. Here one can give default username, password, database name as well various settings related to configuration. Additionally application logging is also possible through the options. A couple of other important points I noticed was the button to reset counters as well status bar containing useful information of Total Threads, Completed Queries and Failed Queries. I use this frequently for my load testing. What tool do you use for SQL Server Load Generator?

  • A good tool for browser automation/client-side Web scripting

    - by hardmath
    I'm interested in adopting a tool/scripting language to automate some daily tasks connected with fighting forum spammers. A brief overview of these tasks: analyze new registrations and posts on a phpBB forum, and delete or deactivate spammers using a website/community that collects such spam reports. Typically such automation is integrated into the phpBB installation itself, which certainly has its advantages. My approach has the advantage of independent operation, etc. One way to think about this is in terms of browser automation. I've used iOpus iMacros for Firefox (the free version) in the past to respond to individual spammers, but current attacks are highly distributed. My "logic" for pigeonholing spammers vs. nonspammers seems beyond the easy reach of the free version of iMacros. From a more technical perspective one can think about dispensing with the browser altogether and programming GET/POST requests directed to my forum and other Web-based resources. I'm familiar with some scripting languages like Ruby and Lua, but I could be persuaded that a compiled application is better suited for these tasks. However in my experience the dynamic flexibility of interpreted environments is very useful in prototyping and debugging the application logic. So I'm leaning in the direction of scripting languages. Among browsers I favor Firefox and Chrome. I use both Windows and Linux platforms, and if the tool can adapt to an Android platform, it would make a neat demonstration of skills, yes? Thanks in advance for your suggestions!

  • Which tools should be used for data migration between environments?

    - by Paula Speranza-Hadley
    Ø  With the Oracle Utilities Application Framework based products there are a number of tools provided that can be used to transfer data from one environment to another. Ø  There are three main tools that implementations use: §  ConfigLab - A configurable copy facility is metadata aware and therefore understands the relationships between objects and by invoking the relevant maintenance objects validates the data copied. This utility uses the object validation to help ensure data integrity. Basically it is a set of configuration tables and a set of batch jobs to perform the migration of data. §  Bundling - A configurable release management tool that allows exporting of Advanced Configuration Environment based objects (business services, business objects, UI Maps etc) from one environment to another. §  Blueprint - An Oracle Utilities Software Development Kit (SDK) based tool to import metadata from the development environment to your initial testing environment. The utility is command line based and basically uses a text based configuration file to drive the utility on the source and target sides. Ø  Each tool has a role in an implementation but you must be careful to use the right tool for the right job within an implementation. The suggestions are as follows: §  Only use the Blueprint tool for migrating data from your development platform to your initial test environment. The blueprint tool is not designed to move large amounts of data and certainly is risky, if not used correctly, and can potentially break the integrity of your data. §  The SDK provides the configuration data that it is used for (mainly meta-data). This should not be extended as, while it can perform data migration on any data, it is not efficient and risky for certain types of configuration data. Ø  Additional information can be found in the following whitepaper:  Oracle Utilities Application Framework - Release Management - Software Configuration Management on MyOracle.com

  • Shared Database Servers

    - by shivanshu.upadhyay
    As more enterprises consolidate their database environments to support private cloud initiatives, ISVs will have to deal with sceanrios where they need to run on a shared powerful database server like Exadata. Some ISVs are concerned about meeting SLAs for performance in a shared environment. Outside the virtualization world, there are capabilities of Oracle Database which can be used to prevent resource contention and guarantee SLA. These capabilities are - 1) Instance Caging - This guarantees the CPU allocated or limits the maximum number of CPUs (and so the number of Oracle processes) that an instance of Database can use simultaneously. With this feature, ISVs can be assured that their application is allocated adequate CPUs even if the database server is shared with other applications. 2) CPU Resource Allocation with Database Resource Manager - This allocates percentages of CPU time to different users and applications within a database. ISVs can use this feature to ensure that priority user or workloads within their application get CPU resources over other requirements. 3) Exadata I/O Resource Manager - The Database Resource Manager feature in Oracle Database 11g has been enhanced for use with Exadata. This allows the sharing of storage between databases without fear of one database monopolizing the I/O bandwidth and impacting the performance of the other databases sharing the storage. This can be used to ensure that I/O does not become a performance bottleneck due to poor design of other applications sharing the same server.

  • Web Sites All Start When Debugging a Web Site - Visual Studio 2010

    - by Daniel Lackey
    I wanted to blog about this because it was an annoyance to me and I couldn't figure out why for quite some time. Have you ever tried debugging one web application in your solution but when you do, all other web sites in your solution build and then start up their respective Visual Studio Development Server? It's not a major problem, but it adds time to waiting for what you are actually trying to debug to start up. After digging through Visual Studio 2010 settings, I finally found the option to turn it off. It is called Always Start When Debugging and is located in the Properties pane for the web project (click on the project .proj file in Visual Studio IDE). This is set to True by default each time you create a new Web Application project. Setting this to false will solve your problems. You will need to set this to false for all web applications in your solution as shown below: In addition, you can set properties on which port the development server uses each time it debugs. This is helpful if you want the port to stay the same for testing purposes. In contrast, you can set it to use a dynamic port each time so if you have a co-worker that is debugging it on a different session on the same server, you won't run into any problems with using the same port. The machine won't allow you to debug two sessions on the same port. Pretty basic stuff but it seemed like a really quirky setting to me.

  • Setting different default applications for different Desktop Environment

    - by Anwar
    I am using Ubuntu 12.04 with default Unity interface. I installed later the KDE desktop, XFCE, LXDE, gnome-shell and Cinnamon. The KDE comes with different default applications than Unity, such as kwrite for text editing, konsole as virtual terminal, kfontview for font viewing and installing, dolphin as File browser etc. Other DE come with some other default applications. The problem arises when you want to open a file such as a text file, with which can both be opened by gedit and kwrite, I want to use kwrite on KDE and gedit on Unity or Gnome. But, there is no way to set like this. I can set default application for text file by changing respective settings in both KDE and Unity, but It become default for both DE. For example, If I set kfontviewer as default font viewing application in KDE, it also opens fonts when I am in Unity or Gnome and vice versa. This is a problem because, loading other DE's program takes long time than the default one for the used DE. My question is: Can I use different default applications for different DE? How?

  • Best option for PDF viewer embedded in web app

    - by RationalGeek
    I have a web app that needs to be able to display a PDF. It needs to allow the user to page through the PDF, and my application needs to be able to know which page is currently being viewed, because other aspects of the web app will change based on the current page. Ideally it would not be dependent on the client having Adobe Reader but I could probably support that dependency. What are my best options for this? My application stack consists of ASP.NET 4 along with optionally Silverlight 5. Also, I could use something that is client-side based as well using JavaScript / HTML if such a thing exists. I found ComponentOne's offering for this and that seems like the leading candidate at this point, but I want to know if there are other options I should consider. Edit: Per Fosco's comment, converting the PDF to another format (such as HTML) might be an option, as long as I could tie back parts of the converted document to the original PDF page #s. Another note: this has to run entirely on our servers. It would not be acceptable to use a third-party service to view the PDFs.

  • Would this be viewed poorly amongst the programming community?

    - by Eric P
    So one of my responsibilities at work is to build an internal tool that helps the workers enter in all their information. It's an enterprise application that is similar to a Windows forms database tool. So it's not much different than like developing a Word + Excel combo application, but the average person in this workgroup is a 20-40 year old woman or a random chatty male type. Plus I know all of these people are heavily involved with Facebook on a daily basis. How bad would it be if I styled my new interface to be similar to what Facebook does. People could get award points and stuff when they fill out different types of forms and basically compete against each other like it was a game. When people had completed one, it would be posted on their wall and everyone could comment/like stuff just like in Facebook. And it would be like they are doing peer reviewing for fun. The rewards would be outstanding I would imagine. These people are so into Facebook and Facebook games that productivity would rise due to them trying to compete and earn points and achievements. Would this be taking advantage of the people by 'tricking them into working harder by giving them a game' or would it be viewed as something that would improve happiness at work?

  • Iphone/Android app – chatroom development – what framework & hosting needs?

    - by MikaelW
    I have some experience regarding IPhone and Android development but I am now struggling to solve a new class of problem: apps that involve a client/server chatroom feature. That is, an app when people can exchange text over the internet, and without having the app to constantly “pull” content from the server. So that problem can’t be solved with a normal php/mysql website, there must be some kind of application running on a server that is able to send message from the server to the phone, rather than having the phone to check for new messages every 10 seconds… So I’m looking for ways to solve the different problems here: What framework should I use on the two sides (phone / server)? It should be some kind of library that doesn’t prevent me to write paid apps. It should also be possible to have the same server for the Iphone and android version of the app. What server / hosting solution do I need with what sort of features, I just have no experience regarding server application that can handle and initiate multiple connections and are hosted on hardware that is always online I tried to find resources online but couldn’t so far, either the libraries had the wrong kind of license/language or I just didn’t understand… Sometimes there were nice tutorial but for different needs such as peer2peer chat over local network… Same with the server and the hosting problem, not sure where to start really, I’m calling for help and I promise I will complete this page with notes about the experience I will get :-) Obviously the ideal would be to find a tutorial I missed that include client code, server code and a free scalable server… That being said, If I see something as good, it probably means that I have eaten the wrong kind of mushroom again… So, failing that, any pointer which might help me toward that quest, would be greatly appreciated. Thanks in advance. Mikael

  • Is there a resource that explains the benefits of layered programming?

    - by P.Brian.Mackey
    Some developers I know favor what I would call a procedural programming style. I recognize that procedural programming has its uses, albeit not in the business application world of .NET programming. So let's say we have a winform application with a buttonclick event. The buttonclick handles everything from the UI configuration to the database call and data manipulation. So you end up with a method that is 100's of lines of code long. Outside the fact that this code can't be considered test-able for various reasons, this style of programming is fragile to change. I can talk bout OO, Anti-patterns, etc. The problem is that any distinct topic I can dream up requires a great deal of explanation to understand the potential benefits. Outside of finding a new job (lots of businesses program this way), how can I teach these kinds of developers how to write better code? Obviously we can't sit around a round table and discuss pro's and con's all day due to time constraints and real work that has to be done. Although, training and intense training is the only thing I can think of to fix these problems. Not to say I write perfect code, I most certainly do not. I do believe there are certain best practices that should be followed as a rule E.G. OO in the context of .NET. The most common excuse I hear is "we can't write code fast enough if we do it like that".

  • Which platform to choose, Java or .NET?

    - by salman
    I am working in a private bank, a leading mid size bank in local market. We are going to create our core banking solution. Existing solution has been developed on Java using IBM Visual Age 4.0. It is very important to discuss architecture first, we have currently more than 350 branches working in standalone mode, and it means they are working in self contained environment. They have their own database server (IBM DB2 9.7) and they are communicating with other branches via sockets to send and receive data. Having experience of .NET for more than 5 years I am trying to convince my superiors to choose .NET platform, but they are reluctant and unwilling. It is my job to encourage them for choosing best available platform to create large scale enterprise application. In simple word, we are going to create a very large scale enterprise financial application, a centralize and integrated which connects all branch networks plus having scalable, solid architecture that easily evolve over time. I want professional people to comment on above scenarios. Which platform to choose .NET or Java? Our all resource is currently working in Java, we have homogeneous environment (no Linux, no Mac and no UNIX). Any idea, any thoughts, any points technical or non-technical i.e. administrative or management point of view will be really appreciated.

  • My boss has a different idea of a website's UX [migrated]

    - by NicoJuicy
    Let me explain the situation. I started transforming a "old (.Net 2.0)" Application into a webapplication. Problem here is, that no-one here is really acquainted with the UX of a website (Simple, efficient). Eventhough, i still have to regard that the website can be tailored to a customer needs through parameters (yeah, i know :s ) For example: I wanted to have a layout similar to invoicemachine (= as simple as possible). -- He wants a Ribbon toolbar. Going to a supplier gives the list of supplier -- He wants to display the "Create Supplier" screen where you can use the wildcards in a certain textbox, to search for a specific Supplier and then give the list of the suppliers. Also, i need 4 search/filter mechanisms: people can search per field with wildmarks can filter the suppliers search a keyword through all the data of a supplier filter the "list Suppliers" page by the first letter of the name. LIST Suppliers | A | D | Z Adam Wrincle ADD |EDIT |Delete Damzel InDistress ADD |EDIT |Delete Zorro ADD |EDIT |Delete I can't seem to get through to him, that the UX of a website needs to be differently than a Windows Application. If he wants to bring all the logic of the windows app into a website, why letting me build a website then? Stick to the old solution. Am i mistaking so hard or how could i convince / show him that an online-solution is something different than the offline solution. He already "saw" online solutions of other applications to get an idea, but if i suggest something he won't listen (if it's GUI / UX related, that is).

  • What deployment framework to use?

    - by jeruki
    We are trying to figure out what deployment method/framework to use with a python application, it has a basic wsgi server to make some REST resources available and a set of static web pages with the interface that are served through apache. The situation is as follows: My team works in isolated parts of the program and sometimes together in specific modules, we have different testing servers and one master server, we all work locally, sync the code using git, and then run a bash script that copies the files from the windows machines to the indicated linux server(using ssh) and then restarts the app. After thinking about it this doesn't seem to be the right way to do it, the script overwrites all the files in the server with the local files everytime. We want to be able to work in the same server without the worry of overwriting other people's code and we need to deploy to different servers to avoid restarting the service while others work with it and in the near future we need to deploy to the master or several clones of the master server when the application reaches a more mature state. We found serveral options capistrano, kwate, chef or fortress, even fleet but we wanted to have opinions from people that has used them to be sure it is what we need. So this are the main questions: Are these the kind of programs we should be looking at to achive a safe concurrent deployment process? Which one have you used/recommend and why? do you think it would help in our actual situation? Thank you so much for your feedback and advice on this.

  • Design of input files reading when it comes to defaults/transformations

    - by Stefano Borini
    Suppose you have an application that reads an input file, on a language that does not support the concept of None. The input is read, parsed, and the contents are stored on a structure for later use. Now, in general you want to keep into account transformation of the data from the input, such as adding default values when not specified, or adding full path information to relative path specified in the input. There are two different strategies to achieve this. The first strategy is to perform these transformations at input file reading time. In practice, you put all the intelligence into the input parser, and your application has no logic to deal with unexpected circumstances, such as an unspecified value. You lose the information of what was specified and what wasn't, but you gain in black-boxing the details. Your "running code" needs that information in any case and in a proper form, and is not concerned if it's the default or a user-specified information. The second strategy is to have the file reader a real one-to-one mapper from the file to a memory-stored object, with no intelligent behavior. unspecified values are not filled (which may however be a problem in languages not supporting None) and data is stored verbatim from the file. The intelligence for recovery must now go into the "running code", which must check what was specified in the file, eventually fall back to a default, or modify the input properly before using it. I would like to know your opinion on these two approaches, and in particular which one you found the most frequently implemented.

  • How do I work around sudo 'segmentation fault' on basic bash commands?

    - by sage
    I am sure the answers are out there, but alas there are too many answers (here and elsewhere) to other questions stopping me from finding them. I just encountered something substantially similar to what is described at the closed SO question, sudo : “segmentation fault” Ubuntu maverick [closed]. My team is using Ubuntu 11.04 on VMWare Workstation 8.0.4. We are doing development using c++, Xenomai, Qt, and Qt Creator. When we simulate our application on the virtual machine, we currently need to launch Qt Creator with sudo. My colleague mentioned today that he has been having issues where his workstation locks up and he needs to restart and that occasionally he has the issue that all sudo bash commands return "segmentation fault". I just ran our application in simulation mode. I was running Qt Creator under sudo and Qt Creator received the signal abort (if I recall). Afterward, every command executed with sudo from sudo qtcreator to sudo ls resulted in the message Segmentation fault. I clicked on the power widget to see if I could log out, but the system shut down straightaway without prompting. My understanding is that we run sudo because of a permissions issue with Xenomai and the VM as currently configured, but my colleague has a workaround for this. I expect that not running Qt Creator under sudo -- something that has always made me nervous -- will help contain this issue, but I find it troubling that this could happen and manifest as it does. Does anyone know what is happening? Any recommendations on how to work around this issue? This is happening often to I am trying tolobby for VM changes to be able to run the process without sudo.

  • How to partition Seagate FreeAgent GoFlex 2TB hard disk?

    - by balki
    Hi I bought a new Seagate 2TB external hard disk. I opened the drive's application in my virtual windows, did product registration using the application present in it. I have few questions on how best to use it. The drive by default has some files and folders - setup.exe, System Volume Information, USB 3.0 PC Card Adapter etc,. I copied all the files to my laptop. Is it safe to delete these files? It has a dash board for windows which allows to tune power options, test the drive etc. Will I be able to use the dash board if I put back all these files and mount on windows again? I want to partition and format the hard disk. Data I like to store is Around 10 to 20 GB Files - Virtual box images. Around 4GB Files - Dvd images. Other Movies and personal Files. What is the best filesystem to store very huge files like 10 to 20GB files. So that they are written and accessed fast also best uses the drive's capacity. If I leave one of the partition as ntfs and others to different files systems, will it be able to mount on windows and Will I be able to use the device's dash board? Note: I dont need any encryption for my data. Any other advice on using the hard disk is also welcome.

  • .NET vs Windows 8: Rematch!

    - by Simon Cooper
    So, although you will be able to use your existing .NET skills to develop Metro apps, it turns out Microsoft are limiting Visual Studio 2011 Express to Metro-only. From the Express website: Visual Studio 11 Express for Windows 8 provides tools for Metro style app development. To create desktop apps, you need to use Visual Studio 11 Professional, or higher. Oh dear. To develop any sort of non-Metro application, you will need to pay for at least VS Professional. I suspect Microsoft (or at least, certain groups within Microsoft) have a very explicit strategy in mind. By making VS Express Metro-only, developers who don't want to pay for Professional will be forced to make their simple one-shot or open-source application in Metro. This increases the number of applications available for Windows 8 and Windows mobile devices, which in turn make those platforms more attractive for consumers. When you use the free VS 11 Express, instead of paying Microsoft, you provide them a service by making applications for Metro, which in turn makes Microsoft's mobile offering more attractive to consumers, increasing their market share. Of course, it remains to be seen if developers forced to jump onto the Metro bandwagon will simply jump ship to Android or iOS instead. At least, that's what I think is going on. With Microsoft, who really knows?
