• Working as an entry .Net Developer in the USA [closed]

  - by Abdullah

  I just have a question about .net entry level jobs in VA. I am a master degree student in field of software engineering but I am graduated from department of physics. I decided to work on Java first, but I have changed my mind because I don't have any Java programming background except Java class in master degree so I decided to work on C# because it was easy to me to work with Visual Studio and it's fun to me to work with SQL database and HTML stuffs. And I am a member of a IT consultant company in Reston where I took course from there about .net and I created online recruitment system for their web site. Now I am applying for CPT (internship) but I didn't work in a company as a .net developer so I don't have experience. Here is my question. If I get CPT and find a job, what do software companies want from an entry level .net developer? and what do they ask as interview questions?

• Use MD5 to validate the exchanged files between Oracle and Customer

  - by Jie Chen

  Oracle Supports may ask customers to upload some data files (Database Dump, Trace Log, etc) for research. We often see the scenario that the uploaded huge files are corrupted and have to ask to re-upload. Then we may waste much time during this period. To avoid this, customers can tell Support the MD5 checksum of the upload files, requesting support to validate same if they have gotten the correct file in good format. MD5 on Linux We can use "md5sum" command directly. For example we calculate the file PrintManager.class MD5 checksum value. [jijichen@jclinux temp]$ md5sum PrintManager.class e0bf8c7623240ccd15ee17c0478427a1 PrintManager.class MD5 on Windows There are many freeware to calculate MD5 on internet. For example we can use WinMD5Free tool. You can download it from here. http://www.winmd5.com https://blogs.oracle.com/jiechen/resource/2013/winmd5free.zip

• Prewritten App for Used Car Dealer?

  - by Shawn Eary

  Is there somewhere I can find a prewritten WebApp (with database) for a used car dealer? The application would need to support the following: Easy setup in a low cost Shared or Cloud Host Give potential customers easy way to browse current inventory (cars on lot) with suggested prices Give dealership easy way to login and update inventory (cars on lot) and suggested prices Give potential customers easy way to send the dealership an inquiry about a specific vehicle on the lot with CAPTCHA style SPAM protection I prefer ASP.NET MVC and Microsoft SQL Server, but I might consider other technologies such as WebForms and LightSwitch (HTML5). I am reasonably comfortable with MVC and WebForms, but I really don't want to waste a bunch of time writing an application that might already exist. I did find a few interesting templates via Bing that seem to control CSS and Layout, but I'm not sure if they contain any business logic or if they would integrate well into an MVC App.

• Choice the project pattern, advice for this case

  - by Lucas Rodrigues Sena

  I have a project in MVC4 entity framework, and have to adapt it to possible updates on the dlls and system do not stop work. I'm using portable Areas, but have difficulty creating 5 modules and about 5 functionality for each modules with fully functioning independently as a dll and database. 1- Reflection DLLs, the system works "on the fly". (I cant do it on mvc4 at moment). 2- Portables Areas (I need to do one area for each modules*functionality 5*5 Areas). Confuse way and I'm afraid if this is ridiculous. 3- Implement WFC on MVC4, compatible? 4- Other better way?

• Tomorrow's web development: What's the bearing?

  - by pex

  I just read a wonderful article about headaches web developers have to live with nowadays. Several questions from that article busied me for some time as well. Now I am wondering whether I missed something, whether there are approaches other than Sproutcore or Cappucino to combine the eternal detached worlds of backend and frontend. How to only write validations once? How to collect business logic in only one model? Are we heading toward a combination of CouchDB Views, NodeJS and minimalistic client-side scripts including plenty of XHR requests? Or shall we follow the direction of handling everything except the database on client side? Is everything about JavaScript? I simply ask for approaches of setting up the next web application, for best practices and promising new technologies and frameworks.

• Channel mit Anspruch

  - by A&C Redaktion

  Den ersten Geburtstag konnte das neue Channel-Programm von Oracle ja bereits Anfang des Jahres feiern. Die Bilanz seitens Oracle ist positiv, doch was sagen die Partner dazu? Opitz Consulting ist einer der Vertriebspartner, die in Deutschland mit mindestens fünf Spezialisierungen das Platin-Level erreicht haben. Sich innerhalb eines Jahres in den Bereichen BI, Database, Enterprise Linux, Real Application Clusters und SOA zu spezialisieren, war keine Kinderspiel, verrät Michael Page, Prokurist bei Opitz Consulting in Interview mit "ChannelPartner": Etwa 15 Prozent seiner Arbeitszeit hat er 2010 darauf verwendet. Ob der nächste Schritt das Diamant-Level sein soll, ließ Page offen. Sicher ist jedoch, dass für den führenden Projektspezialisten im Java-, SOA- und Oracle Markt weitere Spezialisierungen anstehen, darunter Datenbank-Performance-Tuning, Virtualisierung und Data Warehouse. Auch Oracle selbst legt noch mal nach: Zu den 50 Spezialisierungen im OPN Programm werden bis Ende des Jahres weitere 20 hinzukommen, die das Programm für Branchen wie das Gesundheitswesen, Energieversorger oder Retail attraktiv machen sollen. Ausführliche Informationen dazu sowie ein Interview mit Silvia Kaske und Christian Werner von Oracle ist in der aktuellen Ausgabe von "ChannelPartner" (Nr. 4/11 vom 28.2.2011) zu finden.

• How to explain to non-technical person why the task will take much longer then they think?

  - by Mag20

  Almost every developer has to answer questions from business side like: Why is going to take 2 days to add this simple contact form? When developer estimates this task, they may divide it into steps: make some changes to Database optimize DB changes for speed add front end HTML write server side code add validation add client side javascript use unit tests make sure SEO is setup is working implement email confirmation refactor and optimize the code for speed ... These maybe hard to explain to non-technical person, who basically sees the whole task as just putting together some HTML and creating a table to store the data. To them it could be 2 hours MAX. So is there a better way to explain why the estimate is high to non-developer?

• Support for 15,000 Partitions in SQL Server 2008 SP2 and SQL Server 2008 R2 SP1

  In SQL Server 2008 and SQL Server 2008 R2, the number of partitions on tables and indexes is limited to 1,000. This paper discusses how SQL Server 2008 SP2 and SQL Server 2008 R2 SP1 address this limitation by providing an option to increase the limit to 15,000 partitions. It describes how support for 15,000 partitions can be enabled and disabled on a database. It also talks about performance characteristics, certain limitations associated with this support, known issues, and their workarounds. This support is targeted to enterprise customers and ISVs with large-scale decision support or data warehouse requirements.

• Oracle Technology Network Newsletters Revisited

  - by Justin Kestelyn

  You may find this hard to believe, some analysts content that email newsletters are still among the most preferred methods of "information awareness" by developers today. And in our experience, the numbers back it up: subscriptions to Oracle Technology Network newsletters grow organically by 15% every year, even after you take continual list cleanup into account. At this point, we have honed our newsletter strategy to a fine edge; the choices are now: Oracle's Java Developer Newsletter Oracle's Database Application Developer Newsletter (also suitable for DBAs) Oracle's Architect Community Newsletter Oracle's Solaris Community Newsletter (new!) Oracle's .NET Developer Newsletter All of which you can subscribe to here; sample issues also available. Have a taste, you'll like them!

• RoundhousE now supports Oracle, SQL2000

  RoundhousE, the database migration software that is based on sql scripts has added support for Oracle and SQL 2000.

The script errors table captures what went wrong when/if your scripts are not quite up to par or there is some other issue. A special thanks goes out to http://twitter.com/PascalMestdach and http://twitter.com/jochenjonc. They worked hard on this and all I did was provide guidance...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Why does Google Search Engine reject my title tag's change?

  - by Michal P.

  I made a simple webpage http://pundaquitboat.michaelspages.com/ giving it the the title tag "Boat – Pundaquit" and I have submitted it to Google bot by Google Webmaster Tools. Then I decided to change the title to "Anawangin trip" of the same page and I submited my webpage again in the same way to Google bot. The result was that the new title of my webpage coexisted with the old title of the same webpage in SERPs for maybe 2 days. After that the new title was rejected and if I enter site:pundaquitboat.michaelspages.com/ I can see that Google has my old copy of my webpage with old title in its database. This problem doesn't occur in Bing when I can enjoy high position of "Anawangin trip" phrase. (In Bing I haven't submitted the old version of title.)

• PHP Riak in place update

  - by WojonsTech

  From what I can see, when using Riak to update an object, I first need to load the object into PHP, then edit the object, then store the object back to the Riak database. I was wondering if there is a way to update a bucket without pulling it into PHP first. That way, it would save on the network I/O and latency of pulling it into the PHP script. Can objects be edited directly on the Riak side of things? Edit: Is there away to push data to the end of a raik object, so if i have an object that is numeric array can i make a push to add subject that i know its not there or no in place updates what so ever

• What's the format of Real World Performance Day?

  - by william.hardie

  A question that has cropped a lot of late is "what's the format of Real World Performance Day?" Not an unreasonable question you might think. Sure enough, a quick check of the Independent Oracle User Group's website tells us a bit about the Real World Performance Day event, but no formal agenda? This was one of the questions I posed to Tom Kyte (one of the main presenters) in our recent podcast. Tom tells us that this isn't your traditional event where one speaker follows another with loads of slides. In fact, the Real World Performance Day features Tom and fellow Oracle performance experts - Andrew Holdsworth and Graham Wood - continuously on stage throughout the day. All three will be discussing database performance challenges and solutions from development, architectural design and management perspectives. There's going to be multi-terabyte demos on show, less of the traditional slides, and more interactive debate and discussion going on. Tune-in and hear what else Tom has to say about this fairly unique event!

• Cannot Create a connection to Data Source VB 2010 [closed]

  - by CLO_471

  I seem to be having some issues with my Visual Basic 2010. I am trying to create a connection to a data source and it is just not working. Even my old connections in my other projects are not working. When I get into VB I try and create a connection by clicking Add New Data Source Database DataSet New Connection and when I click on New Connection the screen disappears and I am not able to select anything. Does anyone know of a glitch or something? I have checked my ODBC connections and all is good and I have been able to play around with my Access connections (which I am trying to connect) and Queries and everything seems to be working fine. I have rebooted several times, uninstalled and resinstalled VB and have also repaired the entire application. I am not sure what else to try or what else to do. Any help would be much appreciated. My computer specs are XP SP3, Core2 Duo at 2.80 and 3GB RAM

• Is SimplePHPBlog a secure blogging engine?

  - by authentictech

  Has anyone used the blog engine SimplePHPBlog? It is a simple blog engine that uses only text files (no database). My problem with it is that the content directory where the texts files are stored appears to require being world writeable/readable (i.e. permission 777) for it to work. This means anyone can access the text files with a browser! These text files include the blog/comment poster's IP and email address! This is not secure or good practice, right?

• OWB 11.2.0.2: Managing Use of Optional OWB Features

  - by antonio romero

  Most OWB users know that parts of Warehouse Builder are covered with the database license and others require additional options (such as the Oracle Data Integrator Enterprise Edition license). Warehouse Builder 11.2.0.2 adds the ability to disable optional feature groups. This lets you avoid the inadvertent use of most licensed features at the repository level.  This capability is accessed through the 11.2.0.2 Repository Assistant. We’ll look at the basics here. There’s also a new whitepaper that details which features are in the different feature groups associated with licenses. Read on to find out more. In Repository Assistant in 11.2.0.2, in Step 2 (“Choose Operation”), you will see a new task, “Manage Optional Features.” This is where you choose which features to enable or disable.

• System Wide Performance Sanity Check Procedures

  - by user702295

  Do you need to boost your overall implementation performance? Do you need a direction to pinpoint possible performance opportunities? Are you looking for a general performance guide? Try MOS note 69565.1.  This paper describes a holistic methodology that defines a systematic approach to resolve complex Application performance problems.  It has been successfully used on many critical accounts.  The 'end-to-end' tuning approach encompasses the client, network and database and has proven far more effective than isolated tuning exercises.  It has been used to define and measure targets to ensure success.  Even though it was checked for relevance on 13-Oct-2008, the procedure is still very valuable. Regards!

• Is the Mailchimp API available in other languages?

  - by boundaryfunctions

  I'm using the Mailchimp API in combination with PHP and jQuery to provide the subscribing/unsubscribing-actions on a website via Ajax. On errors with user data you get useful messages like "Invalid Email Address", "[email protected] is already subscribed to list x. Click here to update your profile." or "There is no record of "[email protected]" in the database". For sure I want to keep theses messages, but is there a way I can get them in other languages (in particular in German)? How would I achieve this? I wasn't able to find anything about in the Mailchimp docs. I wouldn't like to translate them myself...

• Pre-built Oracle VirtualBox Images

  - by james.bayer

  I’m thrilled to see that Justin Kestelyn has a post that pre-built Oracle VirtualBox images are now available on OTN.  There are VMs for various Oracle software stacks including one for Database, one for Java with Glassfish, and one for SOA and BPM products that includes WebLogic Server. This is just one example of the synergy of a combined Oracle and Sun delivering improvements for customers.  These VMs make it even more straight-forward to get started with Oracle software in a development environment without having to worry about initial software installation and configuration. I’ve been a bit quiet lately on the blogging front, but I’m currently working on another area leveraging the best of Oracle and Sun.  Oracle is uniquely positioned to deliver engineered systems that optimize the entire stack of software and hardware.  You’ve probably seen the announcements about Exalogic and I’m excited about the potential to deliver major advancements for middleware.  More to come…
