• converting dates things from visual basic to c-sharp

  - by sinrtb

  So as an excercise in utility i've taken it upon myself to convert one of our poor old vb .net 1.1 apps to C# .net 4.0. I used telerik code conversion for a starting point and ended up with ~150 errors (not too bad considering its over 20k of code and rarely can i get it to run without an error using the production source) many of which deal with time/date in vb versus c#. my question is this how would you represent the following statement in VB If oStruct.AH_DATE <> #1/1/1900# Then in C#? The converter gave me if (oStruct.AH_DATE != 1/1/1900 12:00:00 AM) { which is of course not correct but I cannot seem to work out how to make it correct.

• Getting out of my head

  - by BenCole

  (I put this on SO, but it got a couple close votes saying it belonged here instead...) I've spent the last year as a single person team developing a rich-client application (35,000+ LoC, for what it's worth). It's currently stable and in production. However, I know that my skills were rusty at the beginning of the project, so without a doubt there are major issues to the code. At this point, most of the issues are in architecture, structure, or interactions - the easy problems, even architecture/design problems, have already been weeded out. Unfortunately, I've spent so much time with this project that I'm having a hard time thinking outside of it - approaching it from a new perspective to see the flaws deeply buried or inherent in the design. How do I step outside my head and outside my code so I can get a fresh look at this code so I can make it better? Is this less of an issue than I think it is, or is this a problem for other people as well?

• JAX-RS 2.0 Early Draft - Third Edition Available

  - by arungupta

  JAX-RS 2.0 Early Draft Third Edition is now available. This updated draft include new samples explaining the features and clarifications in content-negotiation, discovery of providers, client-side API, filters and entity interceptors and several other sections. Provide feedback to users@jax-rs-spec. Jersey 2.0, the Reference Implementation of JAX-RS 2.0, released their fourth milestone a few days ago as well. Several features have already been implemented there. Note, this is an early development preview and several parts of the API and implementation are still evolving. Feel like trying it out? Simply go to Maven Central (of course none of this is production quality at this point). The latest JAX-RS Javadocs and Jersey 2.0 API docs are good starting points to explore. And provide them feedback at [email protected] or @gf_jersey.

• Google Analytics with multiple environments

  - by marcof

  We are planning to use Google Analytics in our organization and I am in charge for setting it up. I was wondering how to deal with multiple environments. We sure do not want to collect data during development and QA (or maybe collect data to a different analytics account), but we want to when the site goes to production (obviously). How do you deal with multiple environments and Google Analytics ? Do you setup multiple accounts for Google Analytics and use either one depending on the environement ? We're using ASP.NET 2.0, if that matters.

• Does 3d modeling software *choice used during asset creation affect performance at runtime

  - by user134143

  Does software used to create 3d assets (for game development specifically) have an impact on the efficiency of the program. In other words. Is it possible to reduce the operating footprint of an application merely by utilizing alternative development software during production of 3d assets. If you use two different applications to create a 3 dimensional image of a box, can one of them result in better performance if aspects of the image are identical? Sorry if this question seems vague, I am attempting to get the information I need without causing unnecessary debate over specific software choice. Thank you.

• Dynamic URL of asp.net web service with web reference

  - by Jalpesh P. Vadgama

  It’s been a while I am writing this. But never late.. So I am writing this. Before some time one of friend asked about the URL of web service when we add reference. So I am writing this. Some of you may find this very basic but still many of people does not know this that’s why I am writing this. In today’s world we have so many servers like development, preproduction and production etc. and for all the server location or URL of web service will be different.But with asp.net when you add a web reference to your web application it’s create a web reference settings in web.config where you can change this path. So it’s very easy to just change that path and you don’t have to add web reference again. Read More

• Are all languages basically the same?

  - by Anirudh

  Recently, i had to understand the design of a small program written in a language i had no idea about (ABAP, if you must know). I could figure it out without too much difficulty. I realize that mastering a new language is a completely different ball game, but purely understanding the intent of code (specifically production standard code, which is not necessarily complex) in any language is straight forward, if you already know a couple of languages (preferably one procedural/OO and one functional). Is this generally true? Are all programming languages made up of similar constructs like loops, conditional statements and message passing between functions? Are there non-esoteric languages that a typical Java/Ruby/Haskell programmer would not be able to make sense of? Do all languages have a common origin?

• Do we set the bar too high by requiring that code tests not suffer from buffer overflow?

  - by brice

  We are currently recruiting for a Junior Developer position working mainly in C on Linux. As part of the process, we require candidates to complete a code test at their leisure in C. So far we have rejected two candidates on the basis that their code, although readable and in one case rather idiomatic, suffered from buffer overflow errors due to unbounded buffer writes. Are buffer overflows acceptable from a graduate developer? Are we setting the bar too high? What is the expected capability of graduate/Junior engineers? [Edit]: We explicitly ask for error-checked, production quality code. We provide a test & build framework for the candidates

• Intermittent Copy/Paste Problem in RDP

  - by Tara Kizer

  If you use RDP to remotely connect to your servers, you've probably encountered a clipboard issue where copy/paste stops working.  A quick Google search on the problem indicates you can easily fix the problem by logging out/logging back in or killing/restarting rdpclip.exe on the remote server.  Here's an article which covers this topic. But what do you do when copy/paste is intermittent?  It works one second, stops working for 5-30 seconds, and then on its own starts working again.  This is what’s occurring in our new non-production environment.  The DBA team is setting up 16 new physical servers and 5 new virtual machines.  I haven’t found a server where this ISN’T happening.  This intermittent copy/paste issue is driving me crazy!

• Calling all developers building ASP.NET applications

  - by Laila Lotfi

  We know that developers building desktop apps have to contend with memory management issues, and we’d like to learn more about the memory challenges ASP.NET developers are facing. To be more specific, we’re carrying out some exploratory research leading into the next phase of development on ANTS Memory Profiler, and our development team would love to speak to developers building ASP.NET applications. You don’t need to have ever used ANTS profiler – this will be a more general conversation about: - your current site architecture, and how you manage the memory requirements of your applications on your back-end servers and web services. - how you currently diagnose memory leaks and where you do this (production server, or during testing phase, or if you normally manage to get them all during the local development). - what specific memory problems you’ve experienced – if any. Of course, we’ll compensate you for your time with a $50 Amazon voucher (or equivalent in other currencies), and our development team’s undying gratitude. If you’d like to participate, please just drop me a line on [email protected].

• Reading 'Index Status' graph in Google Webmaster tools

  - by sam

  I recently found a bunch of old files that had been ftp'ed to a live production server by mistake on a static (html / css / js) site. I manually deleted these files, but today when checking in Google Webmaster tools i found this graph below. The 'update' marker is from 3/9/14, what i can work out is what Google is trying to tell me, are they saying that : There was a ranking update like Penguin or Panda and they penalized my site and un-indexed a load of pages which they thought were junk.. OR Is this showing that I updated the site by deleting the files on the server on 3/9/14 OR Is this something else ?

• while upgrading a virtual machine do I need to install a bootloader

  - by Bond

  I have a virtualization server which is having a few virtual machines running at top of it. All this was done using Ubuntu server edition with KVM and using virt-manager on SSH connection. These VMs are Lucid 10.04 64 bit Vms. When I upgrade them via apt-get upgrade on an SSH connection in between the ncurses screen, it asks me if it should install a bootloader and to select Yes or No for it. I have no clue what should I select here and I cancel the upgrade.Since it is a production machine I can not specify any thing like this. So let me know what will be a correct.

• API design and versioning using EJB

  - by broschb

  I have an API that is EJB based (i.e. there are remote interfaces defined) that most of the clients use. As the client base grows there are issues with updates to the API and forcing clients to have to update to the latest version and interface definition. I would like to possibly look at having a couple versions of the API deployed at a time (i.e. have multiple EAR files deployed with different versions of the API) to support not forcing the clients to update as frequently. I am not concerned about the actual deployment of this, but instead am looking for thoughts and experiences that others have on using EJB's as an API client. How do you support updating versions, are clients required to update? Does anyone run multiple versions in a production environment? Are there pro's cons? Any other experiences or thoughts on this approach, and having an EJB centric API?

• Top Questions and Answers for Pluging into Oracle Database as a Service

  - by David Swanger

  Yesterday we hosted a comprehensive online forum that shared a comprehensive path to help your organization design, deploy, and deliver a Database as a Service cloud. If you missed the online forum, you can watch it on demand by registering here. We received numerous questions.  Below are highlights of the most informative: DBaaS requires a lengthy and careful design efforts. What is the minimum requirements of setting up a scaled-down environment and test it out? You should have an OEM 12c environment for DBaaS administration and then a target database deployment platform that has the key characteristics of what your production environment will look like. This could be a single server or it could be a small pool of hosts if your production DBaaS will be larger and you want to test a more robust / real world configuration with Zones and Pools or DR capabilities for example. How does this benefit companies having their own data center? This allows companies to transform their internal IT to a service delivery model for the database. The benefits to the company are significant cost savings, improved business agility and reduced risk. The benefits to the consumers (internal) of services if much fast provisioning, and response to change in business requirements. From a deployment perspective, is DBaaS's job solely DBA's job? The best deployment model enables the DBA (or end-user) to control the entire process. All resources required to deploy the service are pre-provisioned, and there are no external dependencies (on network, storage, sysadmins teams). The service is created either via a self-service portal or by the DBA. The purpose of self service seems to be that the end user does not rely on the DBA. I just need to give him a template. He decides how much AMM he needs. Why shall I set it one by one. That doesn't seem to be the purpose of self service. Most customers we have worked with define a standardized service catalog, with a few (2 to 5) different classes of service. For each of these classes, there is a pre-defined deployment template, and the user has the ability to select from some pre-defined service sizes. The administrator only has to create this catalog once. Each user then simply selects from the options offered in the catalog.  Looking at DBaaS service definition, it seems to be no different from a service definition provided by a well defined DBA team. Why do you attribute it to DBaaS? There are a couple of perspectives. First, some organizations might already be operating with a high level of standardization and a higher level of maturity from an ITIL or Service Management perspective. Their journey to DBaaS could be shorter and their Service Definition will evolve less but they still might need to add capabilities such as Self Service and Metering/Chargeback. Other organizations are still operating in highly siloed environments with little automation and their formal Service Definition (if they have one) will be a lot less mature today. Therefore their future state DBaaS will look a lot different from their current state, as will their Service Definition. How database as a service impact or help with "Click to Compute" or deploying "Database in cloud infrastructure" DBaaS enables Click to Compute. Oracle DBaaS can be implemented using three architecture models: Oracle Multitenant 12c, native consolidation using Oracle Database and consolidation using virtualization in infrastructure cloud. As Deploy session showed, you get higher consolidating density and efficiency using Multitenant and higher isolation using infrastructure cloud. Depending upon your business needs, DBaaS can be implemented using any of these models. How exactly is the DBaaS different from the traditional db? Storage/OS/DB all together to 'transparently' provide service to applications? Will there be across-databases access by application/user. Some key differences are: 1) The services run on a shared platform. 2) The services can be rapidly provisioned (< 15 minutes). 3) The services are dynamic and can be relocated, grown, shrunk as needed to meet business needs without disruption and rapidly. 4) The user is able to provision the services directly from a standardized service catalog.. With 24x7x365 databases its difficult to find off peak hrs to do basic admin tasks such as gathering stats, running backups, batch jobs. How does pluggable database handle this and different needs/patching downtime of apps databases might be serving? You can gather stats in Oracle Multitenant the same way you had been in regular databases. Regarding patching/upgrading, Oracle Multitenant makes patch/upgrade very efficient in that you can pre-provision a new version/patched multitenant db in a different ORACLE_HOME and then unplug a PDB from its CDB and plug it into the newer/patched CDB in seconds.  Thanks for all the great questions!  If you'd like to learn more and missed the online forum, you can watch it on demand here.

• Design patterns for effects between actors and technology

  - by changelog

  I'm working on my first game, and taking the opportunity to brush up my C++ (I want to make as much of it as portable as I can.) Whilst working on the technology tree and how it affects actors (spaceships, planets, crew, buildings, etc) I can't find a pattern that decouples these entities enough to feel like a clean approach. Just as an idea, here's the type of effects these actors can have on one another (and techs too) An engineer inside a spaceship boosts its shield A hero in a spaceship in a fleet increases morale A technology improves spaceships' travel distance A building in a planet improves its production The best I can come up with is the Observer pattern, and basically manage it more or less manually (when a crew member enters a spaceship, fire the event; when a new building is built in a planet, fire the event, etc etc.) but it seems to be too tightly coupled to me. I would love to get some ideas about how to approach this better.

• BDD: Getting started

  - by thom

  I'm starting with BDD and this is my story: Feature: Months and days to days In order to see months and days as days As a date conversion fan I need a webpage where users can enter days and months and convert them to days. I have some doubts ... Should I write my scenarios before coding anything or should I first write a scenario and then write code, write a scenario again and then write code, and so on ... ? If I should write my scenarios before, can my steps be approved and production code still does not get done? When should I do refactoring on my code? After the feature is done or after each scenario implementation?

• SQL Auto Close Options

  - by Dave Noderer

  Found an interesting thing that others have run across but it is the first time I’ve seen it. A customer emailed to say that the SQL 2008 db that I had helped him with seemed to be going into recovery mode on a regular basis while watching the SQL Management Studio screen. Needless to say he was a bit nervous and about to take some drastic steps. Eventually he found that the Auto Close option was set to true. When this is set to true, the database automatically closes all connections and unlocks the mdf file after 300 milliseconds. When a new connection is made it spins backup… Great for xcopy deployment on a client machine but not a multi-user server based application. So the warning… if you have started a database with SQL express and then move it to a production SQL server, make sure you check that the Auto Close option is set to false. See options screen below:

• Can I get enough experience to get an industry job just by reading books?

  - by MahanGM

  I've been recently working with DirectX and getting familiar with game engines, sub-systems and have done game development for the last 5 years. I have a real question for those whom have worked in larger game making companies before. How is it possible to get to into these big game creators such as Ubisoft, Infinity Ward or EA. I'm not a beginner in my field and I'm going to produce a real nice 2D platform with my team this year, which is the result of 5 years 2D game creation experience. I'm working with prepared engines such as Unity3D or Game Maker software and using .Net with C# to write many tools for our production and proceeding in my way but never had a real engine programming experience 'till now. I'm now reading good books around this topic but I wanted to know: Is it possible to become an employee in big game company by just reading books? I mean beside having an active mind and new ideas and being a solution solver.
