  • Multiple classes in a single .cs file - good or bad?

    - by Sergio
    Is it advisable to create multiple classes within a .cs file or should each .cs file have an individual class? For example: public class Items { public class Animal { } public class Person { } public class Object { } } Dodging the fact for a minute that this is a poor example of good architecture, is having more than a single class in a .cs file a code smell?

  • The Ins and Outs of Effective Smart Grid Data Management

    - by caroline.yu
    Oracle Utilities and Accenture recently sponsored a one-hour Web cast entitled, "The Ins and Outs of Effective Smart Grid Data Management." Oracle and Accenture created this Web cast to help utilities better understand the types of data collected over smart grid networks and the issues associated with mapping out a coherent information management strategy. The Web cast also addressed important points that utilities must consider with the imminent flood of data that both present and next-generation smart grid components will generate. The three speakers, including Oracle Utilities' Brad Williams, focused on the key factors associated with taking the millions of data points captured in real time and implementing the strategies, frameworks and technologies that enable utilities to process, store, analyze, visualize, integrate, transport and transform data into the information required to deliver targeted business benefits. The Web cast replay is available here. The Web cast slides are available here.

  • Bare minimum on the Joel Test

    - by Fung
    From the Joel Test, of the 12, which do you think are the absolute must-haves to at least have a decently running software department/company? I realise there is no absolutely right answer. I'm just trying to get opinions of others out there. My own organization only manages a measly 5 of 12. If you check listings on Careers 2.0, most companies don't score a full 12 either but I'm sure they're doing fine. Does SO publish the stats for those anywhere? Or has anyone tried scrapping the results? Would be interesting to know which are practised the most. And whether because they are easier to implement or whether they actually have the most impact. Thanks.

  • Why do we keep using CSV?

    - by Stephen
    Why do we keep using CSV? I recently made a shift to working the health domain and despite the wonderful work in data transfer standards, all data transfer is in CSV, both for reporting to external organisations, and for data migrations when implementing new systems. Unfortunately the use of CSV is the cause of the endless repetition of the same stupid errors, with the same waste of developer time. (bad escaping, failing to handle null fields etc.) I know we can do better, and anything between JSON and XML (depending on the instance) would be fine. (Most of the time this is data going from one MS SQLserver 2005 to another!) I feel as if each time I see this happening I am literally watching one developer waste anothers time. So why do we keep shafting each other? When will we stop?

  • Tips/Process for web-development using Django in a small team

    - by Mridang Agarwalla
    We're developing a web app uing Django and we're a small team of 3-4 programmers — some doing the UI stuff and some doing the Backend stuff. I'd love some tips and suggestions from the people here. This is out current setup: We're using Git as as our SCM tool and following this branching model. We're following the PEP8 for your style guide. Agile is our software development methodology and we're using Jira for that. We're using the Confluence plugin for Jira for documentation and I'm going to be writing a script that also dumps the PyDocs into Confluence. We're using virtualenv for sandboxing We're using zc.buildout for building This is whatever I can think of off the top of my head. Any other suggestions/tips would be welcome. I feel that we have a pretty good set up but I'm also confident that we could do more. Thanks.

  • How do you KISS ?

    - by Conor
    The KISS principal is a highly quoted design mantra. The aim of this principle is to stamp out unnecessary complexity on a project. This is a good thing, saving time, energy and money. It can lead to a relatively stress free implementation and a simple, elegant, maintainable end product. A lot of discussion on KISS provides mechanisms to simplify requirements, design and implementation. Things that spring to mind include: avoid scope creep; simple obvious design and code; minimal run-time dependencies; refactoring to maintain simplicity; etc. However there are a lot of implicit things that we do to KISS. Examples: small team sizes; minimal management layers; tidy desk; mastery of a single IDE; clear concise error messages; scripts to automate/encapsulate tasks; etc The purpose of this question is to derive a checklist of KISS items. I'm especially interested in non-obvious items.

  • CSS practices: negative positioning

    - by Corey
    I'm somewhat of a novice to CSS. Anyway, I noticed that an extremely common method used in CSS is to have negative or off-screen positioning, whether it be to hide text or preload images or what have you. Even on SE sites, like StackOverflow and this website, have #hlogo a { text-indent: -999999em } set in their CSS. So I guess I have a few questions. is this valid CSS? or is it just a "hack"? are there downsides to doing things this way? why is this so common? aren't there better ways to hide content?

  • Best approach for unit enemy "awareness" in RTS?

    - by Phil
    I'm using Unity3d to develop an RTS/TD hybrid prototype game. What is the best approach to have "awareness" between units and their enemies? Is it sane to have every unit check the distance to every enemy and engage if within range? The approach I'm going for right now is to have a trigger sphere on every unit. If an enemy enters the trigger, the unit becomes aware of the enemy and starts distance checking. I'm imagining that this would save some unnecessary checks? What's the best practice here (if there's such a thing)? Thanks for reading.

  • Linked servers and performance impact: Direction matters!

    - by Linchi Shea
    When you have some data on a SQL Server instance (say SQL01) and you want to move the data to another SQL Server instance (say SQL02) through openquery(), you can either push the data from SQL01, or pull the data from SQL02. To push the data, you can run a SQL script like the following on SQL01, which is the source server: -- The push script -- Run this on SQL01 use testDB go insert openquery(SQL02, 'select * from testDB.dbo.target_table') select * from source_table; To pull the data, you can run...(read more)

  • First time application where to start?

    - by Nazariy
    After many years of searches and copy pasting, I'm still looking for simple solution that can transliterate text input on the fly from one key set to another. There are quite few online services that provide this feature but it still quite annoying to go online all the time. Unfortunately there is not that many applications left which are capable of doing so, and none of them supported by this day. I decided to make my own and at same time to learn something new for my self. The idea is quite simple: application should sit in system tray and wait until input language get changed, for example to Russian. If Russian language is activated, application should start to listen for user key strokes combination and replace them based on custom dictionary for example R = ?, SH = ? etc. I should be able to bind application to any installed language (Russian, Ukrainian, Bulgarian, Belarusian etc.) and customise dictionary for any of them. So my question is: Which language should I chose for this task C++, C# or might be something hardcore like Assembler, as application should work natively with Windows XP/Vista/7 or possibly Mac. (cross platform support is good but my main target is Windows) Due to nature of application behaviour how can I tell anti-virus software that it is not a "Key Logger" and basically not a virus? Where should I start and what should I be aware of? P.S. My current programming knowledge is quite basic, PHP and JavaScript with Object Oriented approach.

  • Sea Monkey Sales & Marketing, and what does that have to do with ERP?

    - by user709270
    Tier One Defined By Lyle Ekdahl, Oracle JD Edwards Group Vice President and General Manager  I recently became aware of the latest Sea Monkey Sales & Marketing tactic. Wait now, what is Sea Monkey Sales & Marketing and what does that have to do with ERP? Well if you grew up in USA during the 50’s, 60’s and maybe a bit in the early 70’s there was a unifying media of culture known as the comic book. I was a big Iron Man fan. I always liked the troubled hero aspect of Tony Start and hey he was a technologist. This is going somewhere, just hold on. Of course comic books like most media contained advertisements. Ninety pound weakling transformed by Charles Atlas in just 15 minutes per day. Baby Ruth, Juicy Fruit Gum and all assortments of Hostess goodies were on display. The best ad was for the “Amazing Live Sea-Monkeys – The real live fun-pets you grow yourself!” These ads set the standard for exaggeration and half-truth; “…they love attention…so eager to please, they can even be trained…” The cartoon picture on the ad is of a family of royal looking sea creatures – daddy, mommy, son and little sis – sea monkey? There was a disclaimer at the bottom in fine print, “Caricatures shown not intended to depict Artemia.” Ok what ten years old knows what the heck artemia is? Well you grow up fast once you’ve been separated from your buck twenty five plus postage just to discover that it is brine shrimp. Really dumb brine shrimp that don’t take commands or do tricks. Unfortunately the technology industry is full of sea monkey sales and marketing. Yes believe it or not in some cases there is subterfuge and obfuscation used to secure contracts. Hey I get it; the picture on the box might not be the actual size. Make up what you want about your product, but here is what I don’t like, could you leave out the obvious falsity when it comes to my product, especially the negative stuff. So here is the latest one – “Oracle’s JD Edwards is NOT tier one”. Really? Definition please! Well a whole host of googleable and reputable sources confirm that a tier one vendor is large, well known, and enjoys national and international recognition. Let me see large, so thousands of customers? Oh and part of the world’s largest business software and hardware corporation? Check and check JD Edwards has that and that. Well known, enjoying national and international recognition? Oracle’s JD Edwards EnterpriseOne is available in 21 languages and is directly localized in 33 countries that support some of the world’s largest multinationals and many midsized domestic market companies. Something on the order of half the JD Edwards customer base is outside North America. My passport is on its third insert after 2 years and not from vacations. So if you don’t mind I am going to mark national and international recognition in the got it column. So what else is there? Well let me offer a few criteria. Longevity – The JD Edwards products benefit from 35+ years of intellectual property development; through booms, busts, mergers and acquisitions, we are still here Vision & innovation – JD Edwards is the first full suite ERP to run on the iPad as just one example Proven track record of execution – Since becoming part of Oracle, JD Edwards has released to the market over 20 deliverables including major release, point releases, new apps modules, tool releases, integrations…. Solid, focused functionality with a flexible, interoperable, extensible underlying architecture – JD Edwards offers solid core ERP with specialty modules for verticals all delivered on a well defined independent tools layer that helps enable you to scale your business without an ERP reimplementation A continuation plan – Oracle’s JD Edwards offers our customers a 6 year roadmap as well as interoperability with Oracle’s next generation of applications Oh I almost forgot that the expert sources agree on one additional thing, tier one may be a preferred vendor that offers product and services to you with appealing value. You should check out the TCO studies of JD Edwards. I think you will see what the thousands of customers that rely on these products to run their businesses enjoy – that is the tier one solution with the lowest TCO. Oh and if you get an offer to buy an ERP for no license charge, remember the picture on the box might not be the actual size.

  • Database design and performance impact

    - by Craige
    I have a database design issue that I'm not quite sure how to approach, nor if the benefits out weigh the costs. I'm hoping some P.SE members can give some feedback on my suggested design, as well as any similar experiences they may have came across. As it goes, I am building an application that has large reporting demands. Speed is an important issue, as there will be peak usages throughout the year. This application/database has a multiple-level, many-to-many relationship. eg object a object b object c object d object b has relationship to object a object c has relationship to object b, a object d has relationship to object c, b, a Theoretically, this could go on for unlimited levels, though logic dictates it could only go so far. My idea here, to speed up reporting, would be to create a syndicate table that acts as a global many-to-many join table. In this table (with the given example), one might see: +----------+-----------+---------+ | child_id | parent_id | type_id | +----------+-----------+---------+ | b | a | 1 | | c | b | 2 | | c | a | 3 | | d | c | 4 | | d | b | 5 | | d | a | 6 | +----------+-----------+---------+ Where a, b, c and d would translate to their respective ID's in their respective tables. So, for ease of reporting all of a which exist on object d, one could query SELECT * FROM `syndicates` ... JOINS TO child and parent tables ... WHERE parent_id=a and type_id=6; rather than having a query with a join to each level up the chain. The Problem This table grows exponentially, and in a given year, could easily grow past 20,000 records for one client. Given multiple clients over multiple years, this table will VERY quickly explode to millions of records and beyond. Now, the database will, in time, be partitioned across multiple servers, but I would like (as most would) to keep the number of servers as low as possible while still offering flexibility. Also writes and updates would be exponentially longer (though possibly not noticeable to the end user) as there would be multiple inserts/updates/scans on this table to keep it in sync. Am I going in the right direction here, or am I way off track. What would you do in a similar situation? This solution seems overly complex, but allows the greatest flexibility and fastest read-operations. Sidenote 1 - This structure allows me to add new levels to the tree easily. Sidenote 2 - The database querying for this database is done through an ORM framework.

  • Friendly URLs: is there a max length for search engines?

    - by Olivier Pons
    People from stackoverflow have been working closely with google team to help them make the panda algorithm more efficient, so I guess they've learned a lot from the google team. Thus they may have done very clever friendly URLs to maximize the page rank. I've seen from time to time very long URLs (can't find where) in stackoverflow, but after a certain "amount" of character there were only numbers, kind of "ok passed this length, SEOs will ignore this so let's put only numbers". I've done a huge work on my framework to make very friendly URLs, and my website can come up with URLs like: http://www.mysite.fr/recherche/region/provence-alpes-cote-d-azur/departement/bouches-du-rhone/categorie-de-metiers/paramedical/ It's very long and I'm wondering if the previous URL won't be mixed with, say, this one: http://www.mysite.fr/recherche/region/provence-alpes-cote-d-azur/departement/bouches-du-rhone/categorie-de-metiers/art/

  • Memory Efficient Windows SOA Server

    - by Antony Reynolds
    Installing a Memory Efficient SOA Suite 11.1.1.6 on Windows Server Well 11.1.1.6 is now available for download so I thought I would build a Windows Server environment to run it.  I will minimize the memory footprint of the installation by putting all functionality into the Admin Server of the SOA Suite domain. Required Software 64-bit JDK SOA Suite If you want 64-bit then choose “Generic” rather than “Microsoft Windows 32bit JVM” or “Linux 32bit JVM” This has links to all the required software. If you choose “Generic” then the Repository Creation Utility link does not show, you still need this so change the platform to “Microsoft Windows 32bit JVM” or “Linux 32bit JVM” to get the software. Similarly if you need a database then you need to change the platform to get the link to XE for Windows or Linux. If possible I recommend installing a 64-bit JDK as this allows you to assign more memory to individual JVMs. Windows XE will work, but it is better if you can use a full Oracle database because of the limitations on XE that sometimes cause it to run out of space with large or multiple SOA deployments. Installation Steps The following flow chart outlines the steps required in installing and configuring SOA Suite. The steps in the diagram are explained below. 64-bit? Is a 64-bit installation required?  The Windows & Linux installers will install 32-bit versions of the Sun JDK and JRockit.  A separate JDK must be installed for 64-bit. Install 64-bit JDK The 64-bit JDK can be either Hotspot or JRockit.  You can choose either JDK 1.7 or 1.6. Install WebLogic If you are using 64-bit then install WebLogic using “java –jar wls1036_generic.jar”.  Make sure you include Coherence in the installation, the easiest way to do this is to accept the “Typical” installation. SOA Suite Required? If you are not installing SOA Suite then you can jump straight ahead and create a WebLogic domain. Install SOA Suite Run the SOA Suite installer and point it at the existing Middleware Home created for WebLogic.  Note to run the SOA installer on Windows the user must have admin privileges.  I also found that on Windows Server 2008R2 I had to start the installer from a command prompt with administrative privileges, granting it privileges when it ran caused it to ignore the jreLoc parameter. Database Available? Do you have access to a database into which you can install the SOA schema.  SOA Suite requires access to an Oracle database (it is supported on other databases but I would always use an oracle database). Install Database I use an 11gR2 Oracle database to avoid XE limitations.  Make sure that you set the database character set to be unicode (AL32UTF8).  I also disabled the new security settings because they get in the way for a developer database.  Don’t forget to check that number of processes is at least 150 and number of sessions is not set, or is set to at least 200 (in the DB init parameters). Run RCU The SOA Suite database schemas are created by running the Repository Creation Utility.  Install the “SOA and BPM Infrastructure” component to support SOA Suite.  If you keep the schema prefix as “DEV” then the config wizard is easier to complete. Run Config Wizard The Config wizard creates the domain which hosts the WebLogic server instances.  To get a minimum footprint SOA installation choose the “Oracle Enterprise Manager” and “Oracle SOA Suite for developers” products.  All other required products will be automatically selected. The “for developers” installs target the appropriate components at the AdminServer rather than creating a separate managed server to house them.  This reduces the number of JVMs required to run the system and hence the amount of memory required.  This is not suitable for anything other than a developer environment as it mixes the admin and runtime functions together in a single server.  It also takes a long time to load all the required modules, making start up a slow process. If it exists I would recommend running the config wizard found in the “oracle_common/common/bin” directory under the middleware home.  This should have access to all the templates, including SOA. If you also want to run BAM in the same JVM as everything else then you need to “Select Optional Configuration” for “Managed Servers, Clusters and Machines”. To target BAM at the AdminServer delete the “bam_server1” managed server that is created by default.  This will result in BAM being targeted at the AdminServer. Installation Issues I had a few problems when I came to test everything in my mega-JVM. Following applications were not targeted and so I needed to target them at the AdminServer: b2bui composer Healthcare UI FMW Welcome Page Application (11.1.0.0.0) How Memory Efficient is It? On a Windows 2008R2 Server running under VirtualBox I was able to bring up both the 11gR2 database and SOA/BPM/BAM in 3G memory.  I allocated a minimum 512M to the PermGen and a minimum of 1.5G for the heap.  The setting from setSOADomainEnv are shown below: set DEFAULT_MEM_ARGS=-Xms1536m -Xmx2048m set PORT_MEM_ARGS=-Xms1536m -Xmx2048m set DEFAULT_MEM_ARGS=%DEFAULT_MEM_ARGS% -XX:PermSize=512m -XX:MaxPermSize=768m set PORT_MEM_ARGS=%PORT_MEM_ARGS% -XX:PermSize=512m -XX:MaxPermSize=768m I arrived at these numbers by monitoring JVM memory usage in JConsole. Task Manager showed total system memory usage at 2.9G – just below the 3G I allocated to the VM. Performance is not stellar but it runs and I could run JDeveloper alongside it on my 8G laptop, so in that sense it was a result!

    Email Alerts, Blog /Forum updates, discussion subscriptions general programming/technology update emails that we often subscribe to.Do you actually read them ? or go direct to the source when you find time. Often we might the mail of programmers filled with loads of unread subscription mail from technology they previously were following or worked on or things they wish to follow .Some or a majority of these mail just keep on piling up . I personally have few updates that i wish i read but constantly avoid and keep of for latter and finally delete them in effort keep the in box clean. Few questions come to mind regarding this Do you keep such mail in separate accounts? Do you read all the mail you have subscribed to? Do you ever unsubscribe to any such email if you aren't reading them? How much do you really value these email. Lastly do you keep your in box clean ? wish to deal with this in a better way.

  • Use of Business Parameters in BPM12c

    - by Abhishek Mittal-Oracle
    With the release of BPM12c, a new feature to use Business Parameters is introduced through which we can define a business parameter which will behave as a global variable which can be used within BPM project. Business Administrator can be the one responsible to modify the business parameters value dynamically at run-time which may bring change in BPM process flow where it is used.This feature was a part of BPM10g product and was extensively used. In BPM11g, this feature is not present currently.Business Parameters can be defined in 2 ways:1. Using Jdev to define business parameters, and 2. Using BPM workspace to define business parameters.It is important to note that business parameters need to be mapped with a valid organisation unit defined in a BPM project. If the same is not handled, exceptions like 'BPM-70702' will be thrown by BPM Engine. This is because business parameters work along with organisation defined in a BPM project.At the same time, we can use same business parameter across different organisation units with different values. Business Parameters in BPM12c has this capability to handle multiple values with different organisation units defined in a single BPM project. This enables business to re-use same business parameters defined in a BPM project across different organisations.Business parameters can be defined using the below data types:1. int2. string 3. boolean4. double While defining an business parameter, it is mandatory to provide a default value. Below are the steps to define a business parameter in Jdev: Step 1:  Open 'Organization' and click on 'Business Parameters' tab.Step 2:  Click on '+' button.Step 3: Add business parameter name, type and provide default value(mandatory).Step 4: Click on 'OK' button.Step 5: Business parameter is defined. Below are the steps to define a business parameter in BPM workspace: Step 1: Login to BPM workspace using admin-username and password.Step 2: Click on 'Administration' on the right top side of workspace.Step 3: Click on 'Business Parameters' in the left navigation panel under 'Organization'. Step 4:  Click on '+' button.Step 5: Add business parameter name, type and provide default value(mandatory).Step 6: Click on 'OK' button.Step 7: Business parameter is defined. Note: As told earlier in the blog, it is necessary to define and map a valid organization ID with predefined variable 'organizationalUnit' under data associations in an BPM process before the business parameter is used. I have created one sample PoC demonstrating the use of Business Parameters in BPM12c and it can be found here.
