  • What real life bad habits has programming given you?

    - by Jacob T. Nielsen
    Programming has given me a lot of bad habits and it continues to give me more everyday. But I have also gotten some bad habits from the mindset that I have put myself in. There simply are some things that are deeply rooted in my nature, though some of them I wish I could get rid of. A few: Looking for polymorphism, inheritance and patterns in all of God's creations. Explaining the size of something in pixels and colors in hex code. Using code related abstract terms in everyday conversations. How have you been damaged?

  • Version Control without CVS

    - by Lo Wai Lun
    My partners and I have been building an application that requires users to authenticate with password and user ID for member registration and transaction. Very often, tasks for designing UI, Datagrid view event trigger and data access using SQL are allocated to different person. Sometimes, there are different versions to be updated but the database structure used are different If everybody finishes their own part and submit the project on their own onto the shared cloud rivers, there must be a huge cost for software maintenance and re-engineering. How should the task to be submitted so as to minimize the cost for re-engineering without the software like winCVS and Tortoise HG?

  • The Data Scientist

    - by BuckWoody
    A new term - well, perhaps not that new - has come up and I’m actually very excited about it. The term is Data Scientist, and since it’s new, it’s fairly undefined. I’ll explain what I think it means, and why I’m excited about it. In general, I’ve found the term deals at its most basic with analyzing data. Of course, we all do that, and the term itself in that definition is redundant. There is no science that I know of that does not work with analyzing lots of data. But the term seems to refer to more than the common practices of looking at data visually, putting it in a spreadsheet or report, or even using simple coding to examine data sets. The term Data Scientist (as far as I can make out this early in it’s use) is someone who has a strong understanding of data sources, relevance (statistical and otherwise) and processing methods as well as front-end displays of large sets of complicated data. Some - but not all - Business Intelligence professionals have these skills. In other cases, senior developers, database architects or others fill these needs, but in my experience, many lack the strong mathematical skills needed to make these choices properly. I’ve divided the knowledge base for someone that would wear this title into three large segments. It remains to be seen if a given Data Scientist would be responsible for knowing all these areas or would specialize. There are pretty high requirements on the math side, specifically in graduate-degree level statistics, but in my experience a company will only have a few of these folks, so they are expected to know quite a bit in each of these areas. Persistence The first area is finding, cleaning and storing the data. In some cases, no cleaning is done prior to storage - it’s just identified and the cleansing is done in a later step. This area is where the professional would be able to tell if a particular data set should be stored in a Relational Database Management System (RDBMS), across a set of key/value pair storage (NoSQL) or in a file system like HDFS (part of the Hadoop landscape) or other methods. Or do you examine the stream of data without storing it in another system at all? This is an important decision - it’s a foundation choice that deals not only with a lot of expense of purchasing systems or even using Cloud Computing (PaaS, SaaS or IaaS) to source it, but also the skillsets and other resources needed to care and feed the system for a long time. The Data Scientist sets something into motion that will probably outlast his or her career at a company or organization. Often these choices are made by senior developers, database administrators or architects in a company. But sometimes each of these has a certain bias towards making a decision one way or another. The Data Scientist would examine these choices in light of the data itself, starting perhaps even before the business requirements are created. The business may not even be aware of all the strategic and tactical data sources that they have access to. Processing Once the decision is made to store the data, the next set of decisions are based around how to process the data. An RDBMS scales well to a certain level, and provides a high degree of ACID compliance as well as offering a well-known set-based language to work with this data. In other cases, scale should be spread among multiple nodes (as in the case of Hadoop landscapes or NoSQL offerings) or even across a Cloud provider like Windows Azure Table Storage. In fact, in many cases - most of the ones I’m dealing with lately - the data should be split among multiple types of processing environments. This is a newer idea. Many data professionals simply pick a methodology (RDBMS with Star Schemas, NoSQL, etc.) and put all data there, regardless of its shape, processing needs and so on. A Data Scientist is familiar not only with the various processing methods, but how they work, so that they can choose the right one for a given need. This is a huge time commitment, hence the need for a dedicated title like this one. Presentation This is where the need for a Data Scientist is most often already being filled, sometimes with more or less success. The latest Business Intelligence systems are quite good at allowing you to create amazing graphics - but it’s the data behind the graphics that are the most important component of truly effective displays. This is where the mathematics requirement of the Data Scientist title is the most unforgiving. In fact, someone without a good foundation in statistics is not a good candidate for creating reports. Even a basic level of statistics can be dangerous. Anyone who works in analyzing data will tell you that there are multiple errors possible when data just seems right - and basic statistics bears out that you’re on the right track - that are only solvable when you understanding why the statistical formula works the way it does. And there are lots of ways of presenting data. Sometimes all you need is a “yes” or “no” answer that can only come after heavy analysis work. In that case, a simple e-mail might be all the reporting you need. In others, complex relationships and multiple components require a deep understanding of the various graphical methods of presenting data. Knowing which kind of chart, color, graphic or shape conveys a particular datum best is essential knowledge for the Data Scientist. Why I’m excited I love this area of study. I like math, stats, and computing technologies, but it goes beyond that. I love what data can do - how it can help an organization. I’ve been fortunate enough in my professional career these past two decades to work with lots of folks who perform this role at companies from aerospace to medical firms, from manufacturing to retail. Interestingly, the size of the company really isn’t germane here. I worked with one very small bio-tech (cryogenics) company that worked deeply with analysis of complex interrelated data. So  watch this space. No, I’m not leaving Azure or distributed computing or Microsoft. In fact, I think I’m perfectly situated to investigate this role further. We have a huge set of tools, from RDBMS to Hadoop to allow me to explore. And I’m happy to share what I learn along the way.

  • SQL Server for the Oracle DBA Links

    - by BuckWoody
    I do a presentation (and a class) called "SQL Server for the Oracle DBA". It's a non-marketing overview that gives you the basics of working with SQL Server if you're already familiar wtih how Oracle works. This class and these links DO NOT help you with "Why should I use Oracle/SQL Server instead of Oracle/SQL Server" - I'll assume you're already there, and if not, there are LOTS of sites to help you make that decision. Although these links might contain slight marketing slants (I don't control them) I've tried to get the best links I can. Feel free to comment here to add more/better links. As such, these aren't links that help you work with Oracle - they are links to help you work with SQL Server. Some of them contain more information than you actually need, others don't have near enough. Taken together (and with the class) you're able to get done what you need to do. "Practical SQL Server for Oracle Professionals" - A Microsoft Whitepaper, probably the best place to get started: http://download.microsoft.com/download/6/9/d/69d1fea7-5b42-437a-b3ba-a4ad13e34ef6/SQLServer2008forOracle.docx Free Training: http://technet.microsoft.com/en-us/sqlserver/dd548020.aspx Classroom training (will cost you): http://www.microsoft.com/learning/en/us/course.aspx?ID=50068A&locale=en-us Terminology Differences: http://www.associatedcontent.com/article/2383466/oracle_and_sql_server_basic_terminology.html Datatype mapping between Oracle and SQL Server: http://msdn.microsoft.com/en-us/library/ms151817.aspx The "other" direction - can still be useful for the Oracle professional to see the other side: http://blog.benday.com/archive/2008/10/23/23195.aspx Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

    How 'Bout a Little Context? Let me be direct with you. I love SQL Saturday . If it were a woman , I'd marry it. (Avoiding all extraneous thoughts of what my real wife would say, etc etc). Check out this fun Flickr Feed from the recent SQL Saturday in Chicago or these picks by Jorge Segara ( blog | twitter ) to see the sort of fun that's in store. But who can argue with a day of free SQL Server training and a chance to network with great presenters and a wide swath of your peers? Keynotes are more...(read more)

  • Performance-Driven Development

    - by BuckWoody
    I was reading a blog yesterday about the evils of SELECT *. The author pointed out that it's almost always a bad idea to use SELECT * for a query, but in the case of SQL Azure (or any cloud database, for that matter) it's especially bad, since you're paying for each transmission that comes down the line. A very good point indeed. This got me to thinking - shouldn't we treat ALL programming that way? In other words, wouldn't it make sense to pretend that we are paying for every chunk of data - a little less for a bit, a lot more for a BLOB or VARCHAR(MAX), that sort of thing? In effect, we really are paying for that. Which led me to the thought of Performance-Driven Development, or the act of programming with the goal of having the fastest code from the very outset. This isn't an original title, since a quick Bing-search shows me a couple of offerings from Forrester and a professional in Israel who already used that title, but the general idea I'm thinking of is assigning a "cost" to each code round-trip, be it network, storage, trip time and other variables, and then rewarding the developers that come up with the fastest code. I wonder what kind of throughput and round-trip times you could get if your developers were paid on a scale of how fast the application performed...

  • How can an experienced web developer transition to desktop development?

    - by Craige
    I'm a web developer, first and foremost. I've been programming for 5 or 6 years now, all of which has been web-based. I'm good at my job, both specifically as a web developer and as a programmer in general. I have decided recently that I would like to learn some desktop programming to to beef up my skill-set. My question is this: How can an experienced web developer transition to desktop development? To elaborate: I have always been a web-developer, and I can design and build web-applications without any problem. When it comes to sitting down with a to learn some desktop oriented programming, my problem isn't with any of the technical matters, but rather coming up with an idea to program. I draw a blank.

  • Tidbits of goodness - Podcasts, REST, JSON

    - by jeff.x.davies
    I've been quiet for a while, busy with a variety of projects. I did want to let you all know about a couple of things going on. First, I have been participating in architectural podcasts with Bob Rhubart. If you are interested in hearing these short (about 10 minutes each) recordings where a group of us discuss enterprise architecture and its future, check out http://blogs.oracle.com/archbeat/2010/05/podcast_show_notes_evolving_en.html Next, I have been working on the public sample code for the Oracle Service Bus 11g release. I'm now expanding my samples to include SCA, BPEL and the Oracle Adapters. This is really great experience for me because I have been learning these other tools to a deeper level and this provides insight into developing better solutions. You know the old saying, "If the only tool you have is a hammer, you tend to appraoch every problem as if it were a nail." However, I'm not the only one working on these samples. We have alot of our best and brightest working on sample code for the 11g release. Take a look at https://soasamples.samplecode.oracle.com/ to see all of the samples for SOA Suite 11g A reader wrote to me and asked me about using OSB to return information in JSON format. I don't have a sample posted for this yet, but I am working on getting one packaged up. In the mean time I can tell you that it is dead simple to do in OSB. Use the instructions I gave in an earlier blog entry on creating REST services using OSB, specify Messaging Service as the service type that takes a Text message and returns a Text message. Then have the OSB proxy service return a JSON formatted string (by replacing the contents of the $body variable with the JSON text) and you're done! This approach allows you to use OSB services from within Javascript/AJAX seamlessly. As I get more samples posted to the OTN site, I'll let you know. I have lots of interesting stuff on the way.

  • Whether to use UNION or OR in SQL Server Queries

    - by Dinesh Asanka
    Recently I came across with an article on DB2 about using Union instead of OR. So I thought of carrying out a research on SQL Server on what scenarios UNION is optimal in and which scenarios OR would be best. I will analyze this with a few scenarios using samples taken  from the AdventureWorks database Sales.SalesOrderDetail table. Scenario 1: Selecting all columns So we are going to select all columns and you have a non-clustered index on the ProductID column. --Query 1 : OR SELECT * FROM Sales.SalesOrderDetail WHERE ProductID = 714 OR ProductID =709 OR ProductID =998 OR ProductID =875 OR ProductID =976 OR ProductID =874 --Query 2 : UNION SELECT * FROM Sales.SalesOrderDetail WHERE ProductID = 714 UNION SELECT * FROM Sales.SalesOrderDetail WHERE ProductID = 709 UNION SELECT * FROM Sales.SalesOrderDetail WHERE ProductID = 998 UNION SELECT * FROM Sales.SalesOrderDetail WHERE ProductID = 875 UNION SELECT * FROM Sales.SalesOrderDetail WHERE ProductID = 976 UNION SELECT * FROM Sales.SalesOrderDetail WHERE ProductID = 874 So query 1 is using OR and the later is using UNION. Let us analyze the execution plans for these queries. Query 1 Query 2 As expected Query 1 will use Clustered Index Scan but Query 2, uses all sorts of things. In this case, since it is using multiple CPUs you might have CX_PACKET waits as well. Let’s look at the profiler results for these two queries: CPU Reads Duration Row Counts OR 78 1252 389 3854 UNION 250 7495 660 3854 You can see from the above table the UNION query is not performing well as the  OR query though both are retuning same no of rows (3854).These results indicate that, for the above scenario UNION should be used. Scenario 2: Non-Clustered and Clustered Index Columns only --Query 1 : OR SELECT ProductID,SalesOrderID, SalesOrderDetailID FROM Sales.SalesOrderDetail WHERE ProductID = 714 OR ProductID =709 OR ProductID =998 OR ProductID =875 OR ProductID =976 OR ProductID =874 GO --Query 2 : UNION SELECT ProductID,SalesOrderID, SalesOrderDetailID FROM Sales.SalesOrderDetail WHERE ProductID = 714 UNION SELECT ProductID,SalesOrderID, SalesOrderDetailID FROM Sales.SalesOrderDetail WHERE ProductID = 709 UNION SELECT ProductID,SalesOrderID, SalesOrderDetailID FROM Sales.SalesOrderDetail WHERE ProductID = 998 UNION SELECT ProductID,SalesOrderID, SalesOrderDetailID FROM Sales.SalesOrderDetail WHERE ProductID = 875 UNION SELECT ProductID,SalesOrderID, SalesOrderDetailID FROM Sales.SalesOrderDetail WHERE ProductID = 976 UNION SELECT ProductID,SalesOrderID, SalesOrderDetailID FROM Sales.SalesOrderDetail WHERE ProductID = 874 GO So this time, we will be selecting only index columns, which means these queries will avoid a data page lookup. As in the previous case we will analyze the execution plans: Query 1 Query 2 Again, Query 2 is more complex than Query 1. Let us look at the profile analysis: CPU Reads Duration Row Counts OR 0 24 208 3854 UNION 0 38 193 3854 In this analyzis, there is only slight difference between OR and UNION. Scenario 3: Selecting all columns for different fields Up to now, we were using only one column (ProductID) in the where clause.  What if we have two columns for where clauses and let us assume both are covered by non-clustered indexes? --Query 1 : OR SELECT * FROM Sales.SalesOrderDetail WHERE ProductID = 714 OR CarrierTrackingNumber LIKE 'D0B8%' --Query 2 : UNION SELECT * FROM Sales.SalesOrderDetail WHERE ProductID = 714 UNION SELECT * FROM Sales.SalesOrderDetail WHERE CarrierTrackingNumber  LIKE 'D0B8%' Query 1 Query 2: As we can see, the query plan for the second query has improved. Let us see the profiler results. CPU Reads Duration Row Counts OR 47 1278 443 1228 UNION 31 1334 400 1228 So in this case too, there is little difference between OR and UNION. Scenario 4: Selecting Clustered index columns for different fields Now let us go only with clustered indexes: --Query 1 : OR SELECT * FROM Sales.SalesOrderDetail WHERE ProductID = 714 OR CarrierTrackingNumber LIKE 'D0B8%' --Query 2 : UNION SELECT * FROM Sales.SalesOrderDetail WHERE ProductID = 714 UNION SELECT * FROM Sales.SalesOrderDetail WHERE CarrierTrackingNumber  LIKE 'D0B8%' Query 1 Query 2 Now both execution plans are almost identical except is an additional Stream Aggregate is used in the first query. This means UNION has advantage over OR in this scenario. Let us see profiler results for these queries again. CPU Reads Duration Row Counts OR 0 319 366 1228 UNION 0 50 193 1228 Now see the differences, in this scenario UNION has somewhat of an advantage over OR. Conclusion Using UNION or OR depends on the scenario you are faced with. So you need to do your analyzing before selecting the appropriate method. Also, above the four scenarios are not all an exhaustive list of scenarios, I selected those for the broad description purposes only.

  • When is the best time to do self learning in relation with software management?

    - by shankbond
    It all started from here. I have been following Software Estimation: Demystifying the Black Art (Best Practices (Microsoft)). The third chapter says that in Software Management: You cannot give too much time to software developers, if you give it to them, then it is likely that extra time given to them will be filled by some other tasks (in other words, the developers will eat that time :)) Parkinson's Law You can also not squeeze the time from their schedule because if you do that, it is likely that they will develop poor quality product, poor design and will hurt you in the long run, there will be a panic situation and total chaos in the project, lots of rework etc. My question is related to the first point. If you don't give enough time then will the typical software engineer learn his/her skills? The market is always coming with new technologies, you need to learn them. Even with the existing familiar technologies there are always best practices and dos and don'ts.

  • What prefer a game developer company? UDK experience or c++ game projects?

    - by momboco
    What prefer a game developer company? A developer with experience in UDK engine ? or, a developer with projects made entirely in c++ with a graphics engine like Ogre3D? I think that a coder can demonstrate better his abilities with games made in c++, because it requires a knowledge deeper in many fields. However, currently there is a lot of companies that develop his games with UDK. Now I don't know if is better specialize in a game engine like UDK.

  • Is rotating the lead developer a good or bad idea?

    - by NickC
    I work on a team that has been flat organizationally since it's creation several months ago. My manager is non-technical and this means that our whole team is responsible for decision-making. My manager is beginning to realize that there are several benefits to having a lead developer, both for his sake (a single point of contact and single responsible party for tasks) and ours (dispute resolution, organized technical guidance, etc.). Because the team has been flat, one concern is that picking one lead developer may discourage the others. A non-developer suggested to my manager that rotating the lead developer is a possible way to avoid this issue. One developer would be lead one month, another the next, and so on. Is this a good idea? Why or why not? Keep in mind that this means all developers — All developers are good, but not necessarily equally suited to leadership. And if it is not, how do I recommend that we avoid this approach without seeming like it's merely for selfish reasons?

  • Tablets Running IDEs

    - by Seth P.
    I am new to the tablet market, but i am trying to learn more. Are any current tablets capable of running programming software such as Visual Studio? I understand they'd have to come up with some kind of streamlined version, but I can imagine the programmers out there excited about the possibility. Does anything like that already exist, or are there rumors of it being available in the near future? Thanks, Seth

  • Automated deployment/installation of development tools

    - by thegreendroid
    My team is looking to automate installation/deployment of all of our development tools. The main driver for this is to ensure that everyone in the team has a consistent development environment setup and to also allow a new recruit to get up and running easily. By development environment I mean tools like SCM, toolchains, IDEs etc. and by consistent I mean everyone using the same version of compiler to build code (this is very important!). Here are a few of our requirements – Allow unattended (silent) install of our entire dev setup by running a single script Ability to deploy selective updates (new versions) for specific tools Ability to report which tools are installed and their specific version numbers Must work on Windows (Linux would be a bonus) Must be easy to maintain What are some of the tools that you've used to automate such a task?

  • Most underestimated programming tool

    - by Anto
    We have many great tools which helps a lot when programming, such as good programmers text editors, IDEs, debuggers, version control systems etc. Some of the tools are more or less "must have" tools for getting the job done (e.g. compilers). There are still always tools which do help a lot, but still don't get so much attention, for various reasons, for instance, when they were released, they were ahead of their time and now are more or less forgotten. What type of programming tool do you think is the most underestimated one? Motivate your answer.

  • Clean file separators in Ruby without File.join

    - by kerry
    I love anything that can be done to clean up source code and make it more readable.  So, when I came upon this post, I was pretty excited.  This is precisely the kind of thing I love. I have never felt good about ‘file separator’ strings b/c of their ugliness and verbosity. In Java we have: 1: String path = "lib"+File.separator+"etc"; And in Ruby a popular method is: 1: path = File.join("lib","etc") Now, by overloading the ‘/’ operator on a String in Ruby: 1: class String 2: def /(str_to_join) 3: File.join(self, str_to_join) 4: end 5: end We can now write: 1: path = 'lib'/'src'/'main' Brilliant!

  • Graffiti is a Sinatra-inspired Groovy Framework

    - by kerry
    Playing around with Sinatra the other day and realized I could really use something like this for Groovy. Thus, Graffiti was born. It’s basically a thin wrapper around Jetty. At first, I thought I might write my own server for it (everybody needs to do that once, don’t they?), but decided to invoke the ’simplest thing that could possibly work’ principle. Here is the requisite ‘Hello World’ example: import graffiti.* @Grab('com.goodercode:graffiti:1.0-SNAPSHOT') @Get('/helloworld') def hello() { 'Hello World' } Graffiti.serve this The code, plus more documentation is hosted under my github account.

    I am beginner in software development. I noticed when I try to learn one technology let's say .NET I loose my grip over other for example Java. I thought it would be better to concentrate on one technology either Java or .NET to make significant advancement and be an expert, because they can be many details which one can ignore when keeps on changing between technologies. Is my decision right? Do experts choose this approach? Update: Should I pursue my career knowing one technology or not?

  • Strict Pomodoro and other time management Chrome extensions

    - by kerry
    I have recently begun using the Pomodoro Technique to increase my productivity. However, I still find myself getting sucked in to the vortex of useless information that is the internet. With that in mind I began searching for a useful chrome extension to replace the Android Pomodoro app I have been using to manage my ‘doros. I even considered writing it myself. Luckily, I stumbled on one that had a similar featureset to what I was looking for. Strict Pomodoro is an excellent Chrome extension for practicing Pomodoro. Though lacking a few key features, such as the ability to set the duration of your pomodoros and breaks, it still has a key feature that helps me stay on task. It blocks time sucking websites. You can set filter lists and it will keep you from accessing them during a Pomodoro. Effectively reminding you to stay on task. Also, the author readily admits that it was quickly put together and new features may be added down the road. For now, it is still an excellent option. For those of you who do not practice Pomodoro but are trying to stay on task. The StayFocusd extension will effectively manage the amount of time you spend on useless (non-productive) sites. It also has a rich feature set that may be better for your work habits. OK, breaks over. Time to get back to work. 25 minutes at a time.
