  • Is 4-5 years the “Midlife Crisis” for a programming career?

    - by Jeff
    I’ve been programming C# professionally for a bit over 4 years now. For the past 4 years I’ve worked for a few small/medium companies ranging from “web/ads agencies”, small industry specific software shops to a small startup. I've been mainly doing "business apps" that involves using high-level programming languages (garbage collected) and my overall experience was that all of the works I’ve done could have been more professional. A lot of the things were done incorrectly (in a rush) mainly due to cost factor that people always wanted something “now” and with the smallest amount of spendable money. I kept on thinking maybe if I could work for a bigger companies or a company that’s better suited for programmers, or somewhere that's got the money and time to really build something longer term and more maintainable I may have enjoyed more in my career. I’ve never had a “mentor” that guided me through my 4 years career. I am pretty much blog / google / self taught programmer other than my bachelor IT degree. I’ve also observed another issue that most so called “senior” programmer in “my working environment” are really not that senior skill wise. They are “senior” only because they’ve been a long time programmer, but the code they write or the decisions they make are absolutely rubbish! They don't want to learn, they don't want to be better they just want to get paid and do what they've told to do which make sense and most of us are like that. Maybe that’s why they are where they are now. But I don’t want to become like them I want to be better. I’ve run into a mental state that I no longer intend to be a programmer for my future career. I started to think maybe there are better things out there to work on. The more blogs I read, the more “best practices” I’ve tried the more I feel I am drifting away from “my reality”. But I am not a great programmer otherwise I don't think I am where I am now. I think 4-5 years is a stage that can be a step forward career wise or a step out of where you are. I just wanted to hear what other have to say about what I’ve mentioned above and whether you’ve experienced similar situation in your past programming career and how you dealt with it. Thanks.

  • Fidelity Investments Life Insurance Executive Weighs in on Policy Administration Modernization

    - by helen.pitts(at)oracle.com
    James Klauer, vice president of Client Services Technology at Fidelity Investment Life Insurance, weighs in on the rationale and challenges associated with policy administration system replacement in this month's digital issue of Insurance Networking News.    In "The Policy Administration Replacement Quandary"  Klauer shared the primary business benefit that can be realized by adopting a modern policy administration system--a timely topic given that recent industry analyst surveys indicate policy administration replacement and modernization will continue to be a top priority for insurers this year.    "Modern policy administration systems are more flexible than systems of the past," Klauer says in the article. " This has allowed us to shorten our delivery time for new products and product changes.  We have also had a greater ability to integrate with other systems and to deliver process efficiencies."   Klauer goes on to advise that insurers ensure they have a solid understanding of the requirements when replacing their legacy policy administration system. "If you can afford the time, take the opportunity to re-engineer your business processes.  We were able to drastically change our death processes, introducing automation and error-proofing." Click here to read more of Klauer's insights and recommendations for best practices in the publication's "Ask & Answered" column.   You also can learn more the benefits of an adaptive, rules-driven approach to policy administration and how to mitigate risks associated with system replacement by attending the free Oracle Insurance Virtual Summit:  Fueling the Adaptive Insurance Enterprise, 10:00 a.m. - 6:00 p.m. EST, Wednesday, January 26.      Insurance Networking News and Oracle Insurance have teamed up to bring you this first-of-its-kind event.

  • MVVM Light Toolkit V3 SP1 for Windows Phone 7

    - by Laurent Bugnion
    He he I start to sound like Microsoft… Anyway… I just released a service pack (SP1) for MVVM Light Toolkit V3. Why? Well mostly because I worked a bit more with the Windows Phone 7 tools that were released at MIX0, and I noticed a few things that could be better in the Windows Phone 7 template. Also, I only found out at MIX that you can actually install custom project templates for Visual Studio Express. For some reason I thought it was not possible. The best way to solve these issues is through a service pack, which consists of a few zip files. Simply follow the instructions on the “Installing Manually” page. You can go ahead and overwrite the files that were installed with V3, all the file structure and names are exactly the same. What? So what do you get in this service pack that was not already in V3? (for more info about what’s new in V3, check the What’s New page). Project and Item templates for Visual Studio 10 Express (phone edition). Unzip these files in your “My Documents” folder, and you can now create a new MVVM Light application in the WinPhone7 version of Visual Studio 2010 Express. Signed assemblies: All the assemblies are now signed, which is a requirement in certain build configurations. XML documentation files: Thanks to Matt Casto for pinging me and reminding me that I had forgotten to include them (doh). New and improved Windows Phone 7 assemblies and templates: This one deserves its own section (see below). What was wrong with the old Silverlight 3 assemblies in Windows Phone 7 projects? It was kind of weird. Functionality wise, it was working just right. However, if you noticed, the EventToCommand behavior was not visible in the Assets tab of Expression Blend, under Behaviors, where it should normally have been. The reason was that even though the Windows Phone 7 is using Silverlight 3, the System.Windows.Interactivity that Blend was expecting is the version that is normally used in Silverlight 4. Yeah, I know, it’s weird. This led me to create a specific version of these assemblies for the phone. The assemblies are located into C:\Program Files\Laurent Bugnion (GalaSoft)\Mvvm Light Toolkit\Binaries\WP7. There are 3 DLLs: GalaSoft.MvvmLight.WP7.dll with RelayCommand, Messenger and ViewModelBase GalaSoft.MvvmLight.Extras.WP7.dll with EventToCommand and DispatcherHelper System.Windows.Interactivity.dll which is the same DLL installed in the Blend SDK, and which is needed for the EventToCommand behavior to work. Happy coding! That’s all! Download and install the service pack according to the instructions on the Installation page, and create your first MVVM Light application for the phone (a blog post will follow later with more details).   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

  • My thoughts on the future of the web with respect to flash, plugins, etc…

    - by joelvarty
    More than 10 years ago I was coding Java applets.  They were great at the time because I could reasonably expect them to run the same way in Netscape and Internet Explorer.  I could also reliably do asynchronous networking back to the server.  But then, Microsoft pulled their native Java runtime from Windows and Internet Explorer.  It got a lot harder to get applets running in people’s browsers. So I started writing ActiveX controls for IE and Java applets for Netscape. Then I switched to Flash, not for too long, but it was enough for me to see that it was a capable and curious implementation of animation, multimedia and script. I even wrote a few Silverlight controls, but then I stopped. I stepped back from all of the “richness” and “interactivity” and I thought about things like accessibility and SEO.  I wondered how my apps and sites might appear to the greater world.  I wondered how the developers I am working with, or who might be inheriting my code down the road, might interact with it. And I thought to myself, What the hell was I thinking? Those embedded controls are not what the web is about, and they run contrary to nearly all of the things that makes the web exciting and fosters innovation within and around.   Those plugins or controls, or whatever you want to refer to them as, are only stop-gaps that fill a hole in the basic HTML/Script/CSS specifications, and that’s all they should ever be used for.  Full stop.  Period.  For instance, I still make use of a nifty little flash control called SWFUpload because it lets me check file size before an upload starts.  I can do the same thing from a Silverlight control.  But rest assured, if I could do this from native javascript, I would in a second.  In fact, the only reason I chose SWFUpload over a ton of other alternatives is that it has a great javascript API so I can do (nearly) all of the UI in regular HTML.  And I ALWAYS provide a non-flash alternative for uploading, and for the rest of any website where the designer has insisted on some piece of creativity that requires flash (usually because the designer is also the flash developer, but that’s an aside…). The web is about openness, and about exposing that openness in such a way that it can be taken advantage of as a small part of a greater whole.  Sure we need security and authentication and ssl and all that stuff, but for me, its something more profound.  For me, the majority of what the web is, is about exposing something that delivers meaning.  What meaning can we derive from an <object> tag?   more later - joel

  • How to bill a client for frequently-interrupted time

    - by Greg
    I find that when I'm working on hourly-billable projects (in particular, those that are research/design/architecture-oriented as opposed to straight coding) that I'm easily distracted by any number of things (email, grab a drink (loss of focus, but nature happens), link off the webpage I was reading, wandering mind (easy when the job calls for a lot of thinking), etc.) This results in very fragmented time, far too incremental IMO to accurately track with a timeclock, and some time very gray. I frequently end up billing for only some fraction of the elapsed time I spent in order to feel fair, but sometimes it takes a really long time to put in an 8-hour day. By contrast, when I've worked for salary I've not worried about whether I'm actively working at any given minute, I just get the job done, and I've never had anything but stellar reviews/feedback from past salaried employers, so I think I get the job done well. I personally believe in an 80/20 cycle: I get 80% of my work done during an inspired 20% of my time. But I have to screw around the other 80% of the time in order to get that first 20%. So the question: what billing/time-tracking policy can I adopt in order to be fair to my hourly customers without having to write off my own less-productive 80% that a salaried employer is willing to overlook in light of the complete package? Note: This question is not about how to be more productive or focused. It's about how to work around whatever salient limitations that I have in a way that's both fair to me and to my customers. Update: A little clarification (to pre-emptively stop some righteous indignation): I currently have a half dozen different project/client groups. It's not a great situation and I'm working at reducing it down to two, but that's my current reality. It's very easy to get off on a thread related to a different project than the one I'm clocking, and I'm not always conscious of it at the time. [I did not intend the question to mean that I was off playing games or making personal calls, etc., and have adjusted wording above to be clearer. Most of the time. I am only human, and sometimes the mind does force you to take a break! :-)]

  • How to prevent ‘Select *’ : The elegant way

    - by Dave Ballantyne
    I’ve been doing a lot of work with the “Microsoft SQL Server 2012 Transact-SQL Language Service” recently, see my post here and article here for more details on its use and some uses. An obvious use is to interrogate sql scripts to enforce our coding standards.  In the SQL world a no-brainer is SELECT *,  all apologies must now be given to Jorge Segarra and his post “How To Prevent SELECT * The Evil Way” as this is a blatant rip-off IMO, the only true way to check for this particular evilness is to parse the SQL as if we were SQL Server itself.  The parser mentioned above is ,pretty much, the best tool for doing this.  So without further ado lets have a look at a powershell script that does exactly that : cls #Load the assembly [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.Management.SqlParser") | Out-Null $ParseOptions = New-Object Microsoft.SqlServer.Management.SqlParser.Parser.ParseOptions $ParseOptions.BatchSeparator = 'GO' #Create the object $Parser = new-object Microsoft.SqlServer.Management.SqlParser.Parser.Scanner($ParseOptions) $SqlArr = Get-Content "C:\scripts\myscript.sql" $Sql = "" foreach($Line in $SqlArr){ $Sql+=$Line $Sql+="`r`n" } $Parser.SetSource($Sql,0) $Token=[Microsoft.SqlServer.Management.SqlParser.Parser.Tokens]::TOKEN_SET $IsEndOfBatch = $false $IsMatched = $false $IsExecAutoParamHelp = $false $Batch = "" $BatchStart =0 $Start=0 $End=0 $State=0 $SelectColumns=@(); $InSelect = $false $InWith = $false; while(($Token = $Parser.GetNext([ref]$State ,[ref]$Start, [ref]$End, [ref]$IsMatched, [ref]$IsExecAutoParamHelp ))-ne [Microsoft.SqlServer.Management.SqlParser.Parser.Tokens]::EOF) { $Str = $Sql.Substring($Start,($End-$Start)+1) try{ ($TokenPrs =[Microsoft.SqlServer.Management.SqlParser.Parser.Tokens]$Token) | Out-Null #Write-Host $TokenPrs if($TokenPrs -eq [Microsoft.SqlServer.Management.SqlParser.Parser.Tokens]::TOKEN_SELECT){ $InSelect =$true $SelectColumns+="" } if($TokenPrs -eq [Microsoft.SqlServer.Management.SqlParser.Parser.Tokens]::TOKEN_FROM){ $InSelect =$false #Write-Host $SelectColumns -BackgroundColor Red foreach($Col in $SelectColumns){ if($Col.EndsWith("*")){ Write-Host "select * is not allowed" exit } } $SelectColumns =@() } }catch{ #$Error $TokenPrs = $null } if($InSelect -and $TokenPrs -ne [Microsoft.SqlServer.Management.SqlParser.Parser.Tokens]::TOKEN_SELECT){ if($Str -eq ","){ $SelectColumns+="" }else{ $SelectColumns[$SelectColumns.Length-1]+=$Str } } } OK, im not going to pretend that its the prettiest of powershell scripts,  but if our parsed script file “C:\Scripts\MyScript.SQL” contains SELECT * then “select * is not allowed” will be written to the host.  So, where can this go wrong ?  It cant ,or at least shouldn’t , go wrong, but it is lacking in functionality.  IMO, Select * should be allowed in CTEs, views and Inline table valued functions at least and as it stands they will be reported upon. Anyway, it is a start and is more reliable that other methods.

  • CodeStock 2012 Review: Michael Eaton( @mjeaton ) - 3 Simple Things for Increased Productivity

    3 Simple Things for Increased ProductivitySpeaker: Michael EatonTwitter: @mjeatonBlog: http://mjeaton.net/blog This was the first time I had seen Michael Eaton speak but have hear a lot of really good things about his speaking abilities. Needless to say I was really looking forward to his session. He basically addressed the topic of distractions and how they can decrease or increase your productivity as a developer. He makes the case that in order to become more productive you must block/limit all distractions. For example, he covered his top distractions as a developer. Top Distractions Social Media(Twitter, Reddit, Facebook) Wiki sites Phone Email Video Games Coworkers, Friends, Family Michael stated that he uses various types of music to help him block out these distractions in order for him to get into his coding zone. While he states that music works for him, he also notes that he knows of others that cannot really work with music. I have to say I am in the latter group because I require a quiet environment in order to work. A few session attendees also recommended listening to really loud white noise or music in another language other than your own. This allows for less focus to be placed on words being sung compared to the rhythmic beats being played. I have to say that I have not tried these suggestions yet but will in the near future. However, distractions can be very beneficial to productivity in that they give your mind a chance to relax and not think about the issues at hand. He spoke highly of taking vacations, and setting boundaries at work so that develops prevent the problem of burnout. One way he suggested that developer’s combat distractions is to use the Pomodoro technique. In his example he selects one task to do for 20 minutes and he can only do that task during that time. He ignores all other distractions until this task or time limit is complete. After it is completed he allows himself to relax and distract himself for another 5- 10 minutes before his next Pomodoro. This allows him to stay completely focused on a task and when the time is up he can then focus on other things.

    Why business needs should shape IT architecture - McKinsey Quarterly - Business Technology - Organization "Too often, efforts to fix architecture issues remain rooted in a company’s IT practices, culture, and leadership. The reason, in part, is that the chief architect—the overall IT-architecture program leader—is frequently selected from within the technical ranks, bringing deep IT know-how but little direct experience or influence in leading a business-wide change program.

  • Anticipating JavaOne 2012 – Number 17!

    - by Janice J. Heiss
    As I write this, JavaOne 2012 (September 30-October 4 in San Francisco, CA) is just over a week away -- the seventeenth JavaOne! I’ll resist the impulse to travel in memory back to the early days of JavaOne. But I will say that JavaOne is a little like your birthday or New Year’s in that it invites reflection, evaluation, and comparison. It’s a time when we take the temperature of Java and assess the world of information technology generally. At JavaOne, insight and information flow amongst Java developers like no other time of the year.This year, the status of Java seems more secure in the eyes of most Java developers who agree that Oracle is doing an acceptable job of stewarding the platform, and while the story is still in progress, few doubt that Oracle is engaging strongly with the Java community and wants to see Java thrive. From my perspective, the biggest news about Java is the growth of some 250 alternative languages for the JVM – from Groovy to Jython to JRuby to Scala to Clojure and on and on – offering both new opportunities and challenges. The JVM has proven itself to be unusually flexible, resulting in an embarrassment of riches in which, more and more, developers are challenged to find ways to optimally mix together several different languages on projects.    To the matter at hand -- I can say with confidence that Oracle is working hard to make each JavaOne better than the last – more interesting, more stimulating, more networking, and more fun! A great deal of thought and attention is being devoted to the task. To free up time for the 475 technical sessions/Birds of feather/Hands-on-Labs slots, the Java Strategy, Partner, and Technical keynotes will be held on Sunday September 30, beginning at 4:00 p.m.   Let’s not forget Java Embedded@JavaOne which is being held Wednesday, Oct. 3rd and Thursday, Oct. 4th at the Hotel Nikko. It will provide business decision makers, technical leaders, and ecosystem partners important information about Java Embedded technologies and new business opportunities.   This year's JavaOne theme is “Make the Future Java”. So come to JavaOne and make your future better by:--Choosing from 475 sessions given by the experts to improve your working knowledge and coding expertise --Networking with fellow developers in both casual and formal settings--Enjoying world-class entertainment--Delighting in one of the world’s great cities (my home town) Hope to see you there!

  • SQL SERVER – LOGBUFFER – Wait Type – Day 18 of 28

    - by pinaldave
    At first, I was not planning to write about this wait type. The reason was simple- I have faced this only once in my lifetime so far maybe because it is one of the top 5 wait types. I am not sure if it is a common wait type or not, but in the samples I had it really looks rare to me. From Book On-Line: LOGBUFFER Occurs when a task is waiting for space in the log buffer to store a log record. Consistently high values may indicate that the log devices cannot keep up with the amount of log being generated by the server. LOGBUFFER Explanation: The book online definition of the LOGBUFFER seems to be very accurate. On the system where I faced this wait type, the log file (LDF) was put on the local disk, and the data files (MDF, NDF) were put on SanDrives. My client then was not familiar about how the file distribution was supposed to be. Once we moved the LDF to a faster drive, this wait type disappeared. Reducing LOGBUFFER wait: There are several suggestions to reduce this wait stats: Move Transaction Log to Separate Disk from mdf and other files. (Make sure your drive where your LDF is has no IO bottleneck issues). Avoid cursor-like coding methodology and frequent commit statements. Find the most-active file based on IO stall time, as shown in the script written over here. You can also use fn_virtualfilestats to find IO-related issues using the script mentioned over here. Check the IO-related counters (PhysicalDisk:Avg.Disk Queue Length, PhysicalDisk:Disk Read Bytes/sec and PhysicalDisk :Disk Write Bytes/sec) for additional details. Read about them over here. If you have noticed, my suggestions for reducing the LOGBUFFER is very similar to WRITELOG. Although the procedures on reducing them are alike, I am not suggesting that LOGBUFFER and WRITELOG are same wait types. From the definition of the two, you will find their difference. However, they are both related to LOG and both of them can severely degrade the performance. Note: The information presented here is from my experience and there is no way that I claim it to be accurate. I suggest reading Book OnLine for further clarification. All the discussion of Wait Stats in this blog is generic and varies from system to system. It is recommended that you test this on a development server before implementing it to a production server.

  • BI Publisher - Hottest Show in Vegas

    - by mike.donohue
    Two days down, two to go. Monday was a very busy and rewarding day. Attended "XML Publisher and FSG for Beginners" given by Susan Behn and Alyssa Johnson from Solution Beacon. It was packed, standing room only ... even though it was at 8:00 am. Later in the afternoon, despite being at the same time and in conflict with other Publisher related sessions, Noelle's session, "The Reporting Platform for Applications: Oracle Business Intelligence Publisher" and my session, "Introduction to Oracle Business Intelligence Publisher" were both very well attended. Immediately following our presentations we ran the BI Publisher Hands On Lab which was great fun. The turnout was so large that unfortunately we could not accommodate everyone who came to the lab. There were as many as 5 people huddled around each of the 20 machines. All the the groups completed the 2 main exercises. Some groups even took the product for an off-road test drive. Look at all the fun we had ... For those who could not attend or want the Hands On Lab document: Hands On Lab Oracle BI Publisher Collaborate 2010.pdf Note that these lab instructions assume a specific set up and files that you may not have in your environment. You can download and install a trial license version of BI Publisher from the download page. Highly recommend taking a look at the additional Tutorials available on OTN. Big thanks to Dan Vlamis and Jonathan Clark from Vlamis Software Solutions and to the Oracle BIWA SIG for setting up these machines and getting the time and space to run this lab. It was inspiring to see all of the attendees successfully creating reports. On Tuesday morning we were up early again for a rousing session of BI Publisher Best Practices that was also, very well attended especially considering the 8 am start. Later that morning saw Ben Bruno from STR Software and two of his customers speak on the additional functionality and ROI they have achieved by using Publisher within EBS and AventX to FAX and Email Publisher generated documents. Spent the afternoon staffing the BI Technology demo pod and had a steady flow of people dropping by with questions. Having a great conference so far and looking forward to the rest of it.

  • April 2010 Critical Patch Update Released

    - by eric.maurice
    Hi, this is Eric Maurice. Today Oracle released the April 2010 Critical Patch Update (CPUApr2010),the first one to include security fixes for Oracle Solaris. Today's Critical Patch Update (CPU) provides 47 new security fixes across the following product families: Oracle Database Server, Oracle Fusion Middleware, Oracle Collaboration Suite, Oracle E-Business Suite, Oracle PeopleSoft Enterprise, Oracle Life Sciences, Retail, and Communications Industry Suites, and Oracle Solaris. 28 of these 47 new vulnerabilities are remotely exploitable without authentication, but the criticality of the affected components and the severity of these vulnerabilities vary greatly. Customers should, as usual, refer to the Risk Matrices in the CPU Advisory to assess the relevance of these fixes for their environment (and the urgency with which to apply the fixes). 7 of the 47 new vulnerabilities affect various versions of Oracle Database Server. None of these 7 vulnerabilities are remotely exploitable without authentication. Furthermore, none of these fixes are applicable to client-only deployments. The most severe CVSS Base Score for the Database Server vulnerabilities is 7.1. As a reminder, information about Oracle's use of the CVSS 2.0 standard can be found in Note 394487.1 (My Oracle Support subscription required). Note that this Critical Patch Update includes fixes for vulnerabilities that were publicly disclosed by David Litchfield at the BlackHat DC Conference in early February (CVE-2010-0866 and CVE-2010-0867). 5 of the 47 new vulnerabilities affect various components of the Oracle Fusion Middleware product family. The highest CVSS Base Score for these vulnerabilities is 7.5. Note that the patches for Oracle WebLogic Server are cumulative and this Critical Patch Update therefore also includes a fix for a vulnerability (CVE-2010-0073) that was the subject of a Security Alert issued by Oracle on February 4, 2010. Customers, who have not applied the previously-released patch, should apply today's Critical Patch Update as soon as possible. As stated at the beginning of this blog, it is also noteworthy to highlight that this Critical Patch Update provides 16 new fixes for the Sun product line. With the recent close of the Sun acquisition both security organizations have worked diligently to align Sun's previous security practices with Oracle's. Java users know that Oracle released a Critical Patch Update for Java SE and Java For Business earlier this month (in accordance with the Java patching schedule previously published by Sun Microsystems). Please note that for the first time, the Java advisories included CVSS Scores to help assess the severity of the new vulnerabilities fixed with the advisory. The rapid inclusion of the Solaris product lines in the Critical Patch Update and the extension of Oracle Software Security Assurance to Sun technologies are evidence of the flexibility of Oracle's security assurance programs. These should also result in tangible security benefits for the users of the Oracle hardware and software stack (such as a predictable patching schedule for all Oracle products).

  • Is inline SQL still classed as bad practice now that we have Micro ORMs?

    - by Grofit
    This is a bit of an open ended question but I wanted some opinions, as I grew up in a world where inline SQL scripts were the norm, then we were all made very aware of SQL injection based issues, and how fragile the sql was when doing string manipulations all over the place. Then came the dawn of the ORM where you were explaining the query to the ORM and letting it generate its own SQL, which in a lot of cases was not optimal but was safe and easy. Another good thing about ORMs or database abstraction layers were that the SQL was generated with its database engine in mind, so I could use Hibernate/Nhibernate with MSSQL, MYSQL and my code never changed it was just a configuration detail. Now fast forward to current day, where Micro ORMs seem to be winning over more developers I was wondering why we have seemingly taken a U-Turn on the whole in-line sql subject. I must admit I do like the idea of no ORM config files and being able to write my query in a more optimal manner but it feels like I am opening myself back up to the old vulnerabilities such as SQL injection and I am also tying myself to one database engine so if I want my software to support multiple database engines I would need to do some more string hackery which seems to then start to make code unreadable and more fragile. (Just before someone mentions it I know you can use parameter based arguments with most micro orms which offers protection in most cases from sql injection) So what are peoples opinions on this sort of thing? I am using Dapper as my Micro ORM in this instance and NHibernate as my regular ORM in this scenario, however most in each field are quite similar. What I term as inline sql is SQL strings within source code. There used to be design debates over SQL strings in source code detracting from the fundamental intent of the logic, which is why statically typed linq style queries became so popular its still just 1 language, but with lets say C# and Sql in one page you have 2 languages intermingled in your raw source code now. Just to clarify, the SQL injection is just one of the known issues with using sql strings, I already mention you can stop this from happening with parameter based queries, however I highlight other issues with having SQL queries ingrained in your source code, such as the lack of DB Vendor abstraction as well as losing any level of compile time error capturing on string based queries, these are all issues which we managed to side step with the dawn of ORMs with their higher level querying functionality, such as HQL or LINQ etc (not all of the issues but most of them). So I am less focused on the individual highlighted issues and more the bigger picture of is it now becoming more acceptable to have SQL strings directly in your source code again, as most Micro ORMs use this mechanism. Here is a similar question which has a few different view points, although is more about the inline sql without the micro orm context: http://stackoverflow.com/questions/5303746/is-inline-sql-hard-coding

  • User Group Meeting Summary - April 2010

    - by Michael Stephenson
    Thanks to everyone who could make it to what turned out to be an excellent SBUG event.  First some thanks to:  Speakers: Anthony Ross and Elton Stoneman Host: The various people at Hitachi who helped to organise and arrange the venue.   Session 1 - Getting up and running with Windows Mobile and the Windows Azure Service Bus In this session Anthony discussed some considerations for using Windows Mobile and the Windows Azure Service Bus from a real-world project which Hitachi have been working on with EasyJet.  Anthony also walked through a simplified demo of the concepts which applied on the project.   In addition to the slides and demo it was also very interesting to discuss with the guys involved on this project to hear about their real experiences developing with the Azure Service Bus and some of the limitations they have had to work around in Windows Mobiles ability to interact with the service bus.   On the back of this session we will look to do some further activities around this topic and the guys offered to share their wish list of features for both Windows Mobile and Windows Azure which we will look to share for user group discussion.   Another interesting point was the cost aspects of using the ISB which were very low.   Session 2 - The Enterprise Cache In the second session Elton used a few slides which are based around one of his customer scenario's where they are looking into the concept of an Enterprise Cache within the organisation.  Elton discusses this concept and also a codeplex project he is putting together which allows you to take advantage of a cache with various providers such as Memcached, AppFabric Caching and Ncache.   Following the presentation it was interesting to hear peoples thoughts on various aspects such as the enterprise cache versus an out of process application cache.  Also there was interesting discussion around how people would like to search the cache in the future.   We will again look to put together some follow-up activity on this   Meeting Summary Following the meeting all slide decks are saved in the skydrive location where we keep content from all meetings: http://cid-40015ea59a1307c8.skydrive.live.com/browse.aspx/.Public/SBUG/SBUG%20Meetings/2010%20April   Remember that the details of all previous events are on the following page. http://uksoabpm.org/Events.aspx   Competition We had three copies of the Windows Identity Foundation Patterns and Practices book that were raffles on the night, it would be great to hear any feedback on the book from those who won it.   Recording The user group meeting was recorded and we will look to make this available online sometime soon.   UG Business The following things were discussed as general UG topics:   We will change the name of the user group to the UK Connected Systems User Group to we are more inline with other user groups who cover similar topics and we believe this will help us to attract more members.  The content or focus of the user group is not expected to change.   The next meeting is 26th May and can be registered at the following link: http://sbugmay2010.eventbrite.com/

  • Should I be wary of signing a non-disclosure agreement with someone I just met?

    - by Thomas Levine
    tl;dr: Some guy I just met says he wants me to join his company. Before he shows me what they do, he wants me to sign a non-disclosure agreement. Is this weird? I'm traveling right now. Someone who saw me coding seemed to think I was smart or something and started talking with me. He explained that he owns a software company, told me a bit about what it does and told me that he was looking for a programmer who would work for a stake in the company. He explained that the company's product is being developed rather secretly, so he couldn't tell me much. But he did tell enough about the product to convince me that he's not completely making this up, which is a decent baseline. He suggested that he show me more of what he's been working on and, after seeing that, I decide whether I want to join. Because of the secrecy behind the product, he wants me to sign a non-disclosure agreement before we talk. I'm obviously somewhat skeptical because of the random nature by which we met. In the short term, I'm wondering if I should be wary of signing such an agreement. He said it would be easier to show me the product in person rather than over the internet, and I'm leaving town tomorrow, so I'd have to figure this out by tomorrow. If I decide to talk with him, I could decide later whether I trust that it's worth spending any time on this company. The concept of being able to avoid telling a secret seems strange to me for the same reason that things like certain aspects of copyright seem strange. Should I be wary of signing a non-disclosure agreement? Is this common practice? I don't know the details of the agreement of which he was thinking, (If I end up meeting with him, I'll of course read over the agreement before I decide whether to sign it.) so I could consider alternatives according to the aspects of the agreement. Or I could just consider the case of an especially harsh agreement. This question seems vaguely related. Do we need a non-disclosure agreement (NDA)? Thanks

  • CodeStock 2012 Review: Michael Eaton( @mjeaton ) - 3 Simple Things for Increased Productivity

    3 Simple Things for Increased ProductivitySpeaker: Michael EatonTwitter: @mjeatonBlog: http://mjeaton.net/blog This was the first time I had seen Michael Eaton speak but have hear a lot of really good things about his speaking abilities. Needless to say I was really looking forward to his session. He basically addressed the topic of distractions and how they can decrease or increase your productivity as a developer. He makes the case that in order to become more productive you must block/limit all distractions. For example, he covered his top distractions as a developer. Top Distractions Social Media(Twitter, Reddit, Facebook) Wiki sites Phone Email Video Games Coworkers, Friends, Family Michael stated that he uses various types of music to help him block out these distractions in order for him to get into his coding zone. While he states that music works for him, he also notes that he knows of others that cannot really work with music. I have to say I am in the latter group because I require a quiet environment in order to work. A few session attendees also recommended listening to really loud white noise or music in another language other than your own. This allows for less focus to be placed on words being sung compared to the rhythmic beats being played. I have to say that I have not tried these suggestions yet but will in the near future. However, distractions can be very beneficial to productivity in that they give your mind a chance to relax and not think about the issues at hand. He spoke highly of taking vacations, and setting boundaries at work so that develops prevent the problem of burnout. One way he suggested that developer’s combat distractions is to use the Pomodoro technique. In his example he selects one task to do for 20 minutes and he can only do that task during that time. He ignores all other distractions until this task or time limit is complete. After it is completed he allows himself to relax and distract himself for another 5- 10 minutes before his next Pomodoro. This allows him to stay completely focused on a task and when the time is up he can then focus on other things.

  • BAM design pointers

    - by Kavitha Srinivasan
    In working recently with a large Oracle customer on SOA and BAM, I discovered that some BAM best practices are not quite well known as I had always assumed ! There is a doc bug out to formally incorporate those learnings but here are a few notes..  EMS-DO parity When using EMS (Enterprise Message Source) as a BAM feed, the best practice is to use one EMS to write to one Data Object. There is a possibility of collisions and duplicates when multiple EMS write to the same row of a DO at the same time. This customer had 17 EMS writing to one DO at the same time. Every sensor in their BPEL process writes to one topic but the Topic was read by 1 EMS corresponding to one sensor. They then used XSL within BAM to transform the payload into the BAM DO format. And hence for a given BPEL instance, 17 sensors fired, populated 1 JMS topic, was consumed by 17 EMS which in turn wrote to 1 DataObject.(You can image what would happen for later versions of the application that needs to send more information to BAM !).  We modified their design to use one Master XSL based on sensorname for all sensors relating to a DO- say Data Object 'Orders' and were able to thus reduce the 17 EMS to 1 with a master XSL. For those of you wondering about how squeaky clean this design is, you are right ! This is indeed not squeaky clean and that brings us to yet another 'inferred' best practice. (I try very hard not to state the obvious in my blogs with the hope that everytime I blog, it is very useful but this one is an exception.) Transformations and Calculations It is optimal to do transformations within an engine like BPEL. Not only does this provide modelling ease with a nice GUI XSL mapper in JDeveloper, the XSL engine in BPEL is quite efficient at runtime as well. And so, doing XSL transformations in BAM is not quite prudent.  The same is true for any non-trivial calculations as well. It is best to do all transformations,calcuations and sanitize the data in a BPEL or like layer and then send this to BAM (via JMS, WS etc.) This then delegates simply the function of report rendering and mechanics of real-time reporting to the Oracle BAM reporting tool which it is most suited to do. All nulls are not created equal Here is yet another possibly known fact but reiterated here. For an EMS with an Upsert operation: a) If Empty tags or tags with no value are sent like <Tag1/> or <Tag1></Tag1>, the DO will be overwritten with --null-- b) If Empty tags are suppressed ie not generated at all, the corresponding DO field will NOT be overwritten. The field will have whatever value existed previously.  For an EMS with an Insert operation, both tags with an empty value and no tags result in –null-- being written to the DO. Hope this helps .. Happy 4th!

  • What type of interview questions should you ask for "legacy" programmers?

    - by Marcus Swope
    We have recently been receiving lots of applicants for our open developer positions from people who I like to refer to as "legacy" programmers. I don't like the term "old" because it seems a little prejudiced (especially to HR!) and it doesn't accurately reflect what I mean. We are a company that does primarily .NET development using TDD in an Agile environment, we use Git as a source control system, we make heavy use of OSS tools and projects and we contribute to them as well, we have a strong bias towards adhering to strong Object-Oriented principles, SOLID, etc, etc, etc... Now, the normal list of questions that we ask doesn't really seem to apply to applicants that are fresh out of school, nor does it seem to apply to these "legacy" programmers. Here is how I (loosely) define a "legacy" programmer. Spent a significant amount of their career working almost exclusively with Assembly/Machine Languages. Primary accomplishments include work done with TANDEM systems. Has extensive experience with technologies like FoxPro and ColdFusion It's not that we somehow think that what we do is "better" than what they do, on the contrary, we respect these types of applicants and we are scared that we may be missing a good candidate. It is just very difficult to get a good read on someone who is essentially speaking a different language than you. To someone like this, it seems a little strange to ask a question like: What is the difference between an abstract class and an interface? Because, I would think that they would almost never know the answer or even what I'm talking about. However, I don't want to eliminate someone who could be a very good candidate in their own right and could be able to eventually learn the stuff that we do. But, I also don't want to just ask a bunch of behavioral questions, because I want to know about their technical background as well. Am I being too naive? Should "legacy" programmers like this already know about things like TDD, source control strategies, and best practices for object-oriented programming? If not, what questions should we ask to get a good representation about whether or not they are still able to learn them and be able to keep up in our fast-paced environment? EDIT: I'm not concerned with whether or not applicants that meet these criteria are in general capable or incapable, as I have already stated that I believe that they can be 100% capable. I am more interested in figuring out how to evaluate their talents, as I am having a hard time figuring out how to determine if they are an A+ "legacy" programmer or if they are a D- "legacy" programmer. I've worked with both.

  • ROA on top of SOA

    - by Vaibhav Pujari
    I already have a stable Service Oriented Architecture for my application which exposes services as API calls. (the verbs) Now, I need to build a Resource Oriented Architecture to expose a RESTful API to interact with the application objects. (the nouns) What are the best practices to reuse the existing services: - without any persistence inside my new code. - without putting unnecessary logic into the REST layer i.e. it should ideally just leverage the services provided by SOA API. I want this layer to be as thin as possible. - without modifying the existing SOA API - allow easy extension of the REST API i.e. it should be easy to add more resources without changing the (yet to be written) core code. (I want to make resource names and their associated actions configurable so more contributors can easily add resources without a need to understand my module) Any advices/suggestions how to achieve this? Edit: Adding more info My Stack: My existing stacks is in Java. But since I plan to just use the services, I don't think that should affect the design of new REST code. I am planning to implement the new REST code in PHP. How well the services map to resources? Some services are mapped well i.e. there are services for creating, updating application objects. But for other application objects, there are no direct services available. More importantly, there are actions beyond just create, update etc. that apply to application objects. And I would like to provide some way for these actions to be exposed through REST. Since these are verbs, how do I deal with them? Where exactly I need help? I would appreciate any help towards high level design to accomplish the task along-with making the framework extendible. For instance, tomorrow there are some new services added to my SOA layer, I want to make sure it is easy for a fresh developer to write a REST call by simply registering a new resource (in a config file/db) and write code for connecting it with SOA calls. Just like plugin.

  • PeopleSoft HCM @ OHUG 11: Enter the Matrix

    - by Jay Zuckert
    The PeopleSoft HCM team is back from a very busy and exciting OHUG conference in Orlando. The packed, standing-room only PeopleSoft HCM Roadmap keynote was the highlight of the conference for many attendees and the reviews are in : PeopleSoft rocked the house ! Great demonstration of products in the keynote. Best keynote in a long time, and fun. Engaging and entertaining, great demonstration of capabilities. Message received loud and clear, PeopleSoft applications are here to stay.  PeopleSoft has a real vision moving forward. Real-time polls using mobile texting were cutting edge.                          Tracy Martin (as Trinity) and other members of the PeopleSoft HCM team presented a ‘must-see’ Matrix-themed session while dressed as movie characters. The keynote highlighted planned HCM capabilities for Matrix administration and future organization visualization enhancements. The team also previewed the planned Manager Dashboard and Talent Summary.                           Following the keynote, some of the cast posed for photo opportunities at the OHUG booth in the exhibition hall. As you can imagine, they received some interesting looks walking by the other vendor booths. The PeopleSoft HCM team also presented numerous other OHUG sessions covering PeopleSoft Talent Management, Compensation, HR HelpDesk, Payroll, Global HCM Practices, Time & Labor, Absence Management, and Benefits. All of those presentations are available from the OHUG site at www.ohug.org. When not in one of the well-attended PeopleSoft HCM sessions, conference attendees filled the Oracle booth in the exhibition hall to see live product demonstrations. True to their PeopleSoft roots, some of the PeopleSoft HCM team played as hard as they worked in Orlando and enjoyed the OHUG Appreciation event along with customers at the Hard Rock. We are already busy planning for Oracle OpenWorld 2011 and prepping sessions our PeopleSoft HCM customers are sure to like. We hope to see you there in San Francisco from Oct. 2-6.

  • Fluid VS Responsive Website Development Questions

    - by Aditya P
    As I understand these form the basis for targeting a wide array of devices based on the browser size, given it would be a time consuming to generate different layouts targeting different/specific devices and their resolutions. Questions: Firstly right to the jargon, is there any actual difference between the two or do they mean the same? Is it safe to classify the current development mainly a html5/css3 based one? What popular frameworks are available to easily implement this? What testing methods used in this regard? What are the most common compatibility issues in terms of different browser types? I understand there are methods like this http://css-tricks.com/resolution-specific-stylesheets/ which does this come under?. Are there any external browser detection methods besides the API calls specific to the browser that are employed in this regard? Points of interest [Prior Research before asking these questions] Why shouldn't "responsive" web design be a consideration? Responsive Web Design Tips, Best Practices and Dynamic Image Scaling Techniques A recent list of tutorials 30 Responsive Web Design and Development Tutorials by Eric Shafer on May 14, 2012 Update Ive been reading that the basic point of designing content for different layouts to facilitate a responsive web design is to present the most relevant information. now obviously between the smallest screen width and the highest we are missing out on design elements. I gather from here http://flashsolver.com/2012/03/24/5-top-commercial-responsive-web-designs/ The top of the line design layouts (widths) are desktop layout (980px) tablet layout (768px) smartphone layout – landscape (480px) smartphone layout – portrait (320px) Also we have a popular responsive website testing site http://resizemybrowser.com/ which lists different screen resolutions. I've also come across this while trying to find out the optimal highest layout size to account for http://stackoverflow.com/questions/10538599/default-web-page-width-1024px-or-980px which brings to light seemingly that 1366x768 is a popular web resolution. Is it safe to assume that just accounting for proper scaling from width 980px onwards to the maximum size would be sufficient to accommodate this? given we aren't presenting any new information for the new size. Does it make sense to have additional information ( which conflicts with purpose of responsive web design) to utilize the top size and beyond?

  • SQL SERVER – NTFS File System Performance for SQL Server

    - by pinaldave
    Note: Before practicing any of the suggestion of this article, consult your IT Infrastructural Admin, applying the suggestion without proper testing can only damage your system. Question: “Pinal, we have 80 GB of data including all the database files, we have our data in NTFS file system. We have proper backups are set up. Any suggestion for our NTFS file system performance improvement. Our SQL Server box is running only SQL Server and nothing else. Please advise.” When I receive questions which I have just listed above, it often sends me deep thought. Honestly, I know a lot but there are plenty of things, I believe can be built with community knowledge base. Today I need you to help me to complete this list. I will start the list and you help me complete it. NTFS File System Performance Best Practices for SQL Server Disable Indexing on disk volumes Disable generation of 8.3 names (command: FSUTIL BEHAVIOR SET DISABLE8DOT3 1) Disable last file access time tracking (command: FSUTIL BEHAVIOR SET DISABLELASTACCESS 1) Keep some space empty (let us say 15% for reference) on drive is possible (Only on Filestream Data storage volume) Defragement the volume Add your suggestions here… The one which I often get a pretty big debate is NTFS allocation size. I have seen that on the disk volume which stores filestream data, when increased allocation to 64K from 4K, it reduces the fragmentation. Again, I suggest you attempt this after proper testing on your server. Every system is different and the file stored is different. Here is when I would like to request you to share your experience with related to NTFS allocation size. If you do not agree with any of the above suggestions, leave a comment with reference and I will modify it. Please note that above list prepared assuming the SQL Server application is only running on the computer system. The next question does all these still relevant for SSD – I personally have no experience with SSD with large database so I will refrain from comment.
