• What relationship do software Scrum or Lean have to industrial engineering concepts like theory of constraints?

  - by DeveloperDon

  In Scrum, work is delivered to customers through a series of sprints in which project work is time boxed to a fixed number of days or weeks, usually 30 days. In lean software development, the goal is to deliver as soon as possible, permitting early feedback for the next iteration. Both techniques stress the importance of workflow in which software work product does not accumulate in development awaiting release at some future date. Both permit new or refined requirements and feedback from QA and customers to be acted on with as little delay as possible based on priority. A few years ago I heard a lecture where the speaker talked briefly about a family of concepts from industrial engineering called theory of constraints. In the factory, they use an operations model based on three components: drum, buffer, and rope. The drum synchronizes work product as it flows through the system. Buffers that protect the system by holding output from one stage as it waits to be consumed by the next. The rope pulls product from one work station to the next. Historically, are these ideas part of the heritage of Scrum and Lean, or are they on a separate track? It we wanted to think about Scrum and Lean in terms of drum-buffer-rope, what are the parts? Drum = {daily scrum meeting, monthly release)? Buffer = {burn down list, source control system)? Rope = { daily meeting, constant integration server, monthly releases}? Industrial engineers define work flow in terms of different kinds of factories. I-Factories: straight pipeline. One input, one output. A-Factories: many inputs and one output. V-Factories: one input, many output products. T-Plants: many inputs, many outputs. If it applies, what kind of factory is most like Scrum or Lean and why?

• I Blame SNMP!

  - by brendonpage

  Anyone who has been reading my blog would have noticed that I have deviated slightly from my original post plan! This post was meant to be on uploading files in Silverlight, so what happened you may ask? Well last weekend I had some friends over for a LAN and one of them brought a managed switch with, which he had just been purchased for work. He proceeded show me how cool it was, how he planned on improving his work network and how it can be monitored remotely via SNMP. After this explanation he started to google for a free SNMP graphing tool. After a few hours of hearing disgruntled mutterings from him I asked what was wrong, he proceeded to rant about how he couldn’t find any tools that suited his needs. It was at this point I though the most dangerous thing a programmer can ever think “I wonder how hard it would be to make one”, of course the answer at the time is always “It can’t be that hard”, and so started my journey into SNMP. I am still in the early stages of this journey so I don’t have to much to report yet, but once I have finished the first version of my SNMP graphing tool I will definitely be posting about it! For now if there are any of you who are interested in doing any SNMP development in C# I would recommend looking at the #Sharp project on CodePlex (http://sharpsnmplib.codeplex.com/), it is the SNMP library I have decided to use and thus far it works beautifully.

• MVVM Light V4.1 with support for Windows Phone 8

  - by Laurent Bugnion

  Today is a very exciting day: After the official release of Windows 8 (and Microsoft Surface!) on Friday, and the official release of Windows Phone 8 on Monday, the Build conference is starting! This is the conference in which we will learn all about the developer experience for Windows 8 and Windows Phone 8. As a partner of Microsoft, I had the privilege of trying out some of the new things early, and this gave me the opportunity to port MVVM Light to Windows Phone 8 (it was already running for Windows 8), and today I am officially publishing this new version. Before you go and update, please not the following: V4.1 (4.1.24.0) only supports Visual Studio 2012 (and Express). If for some reason you are still using Visual Studio 2010, don’t despair! In the next few days I will publish an update supporting these versions as well. But for now, please only upgrade if you are on VS12! That being said, here we go: The download page is available on Codeplex and you can download the updated MSI and install it. Please make sure to read the Readme HTML page that automatically opens in your web browser after the MSI completes! It contains important information on how to install selected Project and Item templates for the frameworks of your choice. This version also support the following versions of Visual Studio: Visual Studio 2012 Pro, Premium, Ultimate Visual Studio 2012 Express for Windows 8 Visual Studio 2012 Express for Windows Phone 8 Visual Studio 2012 Express for Web (Silverlight 4, Silverlight 5) Visual Studio 2012 Express for Windows Desktop (WPF3.5, WPF4, WPF4.5) We also support Expression Blend of course. Windows Phone 8 and Windows 8 are very very exciting opportunities for developers in the whole world. There are already a number of apps running on top of MVVM Light in the Windows Store and of course a large range of apps for Windows Phone too. With this release, we hope to support the developers and speed up application development. It is a pleasure to serve such an innovative and creative community! Happy coding Laurent   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

• Web.NET event coming in October

  - by Chris Massey

  If you’re a web developer in Europe (or would like an excuse to travel to Europe), you should definitely take a look at the Web.NET event coming in October. It’s being organized by two Italian web maestros (Simone Chiaretta and Ugo Lattanzi) and the session list looks fantastic. The event site pretty much speaks for itself, but here’s a quick version: It’s a free one-day event on October 20th, with a huge variety of great sessions by great speakers, all 100% focused on web development. There’s a pizza-fuelled hackathon in the evening; thrills, spills and hot new skills. It’s a great chance to network with the local (in relative terms) web development community. It’s free (although all donations are very greatly appreciated). It’s in Milan, darling. Here’s what you need to do: Go and register on www.webnetconf.eu, and vote on which sessions you think look the most interesting. I know this will be a difficult process – it’s *very* hard to choose – but persevere! Grab your place when the free tickets become available early next month (places are limited). Come to Milan in October, learn some new skills, meet some great people, and maybe build something awesome if you feel like staying up late. I’ll be there, and hopefully I’ll see you on the day.

• Use Those Schemas, People!

  - by BuckWoody

  Database Schemas are just containers – they aren’t users or anything else – think of a sub-directory on the hard drive. In early versions of SQL Server we “hid” schemas, placing all objects under “dbo”, which gave the erroneous perception that Schemas are users. In SQL Server 2005, we “un-hid” or re-introduced schemas within the database. Users can have a default schema (a place where their new objects go), you can add new schemas and transfer objects between them, and they have many other benefits. But I still see a lot of applications, developed by shops I know as well as vendors, that don’t make use of a Schema. Everything is piled under dbo. I completely understand this – since permissions can be granted to a schema, they feel a lot like a user, so it’s just easier not to worry about both users and schemas when you create a database. But if you’ll use them properly you can make your application more understandable and portable. You should at least take a few minutes and read more about them – you owe it to your users: http://msdn.microsoft.com/en-us/library/ms190387.aspx Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• Mouse doesn't work & internet connection not made in Ubuntu 12.04 LTS

  - by David Skare

  Yesterday, Nov 15, 2012, I booted into my Ubuntu 12.04 LTS system. It has resided on a Crucial 128 GB SSD with about 90% free space since early summer. I also have Windows 7 loaded on another Crucial 256 GB SSD. Ubuntu has set up a dual boot system for me even though each OS has its own SSD. I have been using this setup without problems since summer. Yesterday, when the boot process finished, my Microsoft Comfort Mouse 3000 did not work and there was a message that Ubuntu was not connected to the internet. So w/o the mouse I was forced to turn the machine off manually. About 4 days ago Ubuntu worked fine and booting into Win 7 also works fine. I have a backup machine with the same style mouse on it so I swapped the mouse onto this system. Same results. But both mice work when booting into Win 7. Today I removed both SSDs and installed my Ubuntu 12.04 HD which has not been used since I moved Ubuntu to the SSD from it. Same results. Between the last time I used Ubuntu 12.04 on the SSD and when I tried to use it again I made no changes to my machine, either hardware or software. My machines specs are: AMD FX-6100, MSI 990FXA-GD65 AM3+ format with latest BIOS (Ver 19.9), Corsair Vengeance 1866 MHz memory - 16 GB (4GB X 4 sticks), MSI N580GTX video card (nVidia 306.97 drivers), Sony Bravia 32" HD TV as a monitor, Pioneer BluRay DVD-RW, DSL connection to internet thru a router (10 mps), Crucial 128 GB SSD (90% free space), Microsoft Comfort Mouse 3000 I try to maintain current BIOS and drivers for all devices. I mostly use my Ubuntu system for programming in GCC and OpenCOBOL, surfing the internet and e-mailing. No games are installed. I'm stumped! If anyone has experienced this same problem I'd appreciate knowing how you solved it. TIA, Dave

• JDK bug migration: bugs.sun.com now backed by JIRA

  - by darcy

  The JDK bug migration from a Sun legacy system to JIRA has reached another planned milestone: the data displayed on bugs.sun.com is now backed by JIRA rather than by the legacy system. Besides maintaining the URLs to old bugs, bugs filed since the migration to JIRA are now visible too. The basic information presented about a bug is the same as before, but reformatted and using JIRA terminology: Instead of a "category", a bug now has a "component / subcomponent" classification. As outlined previously, part of the migration effort was reclassifying bugs according to a new classification scheme; I'll write more about the new scheme in a subsequent blog post. Instead of a list of JDK versions a bug is "reported against," there is a list of "affected versions." The names of the JDK versions have largely been regularized; code names like "tiger" and "mantis" have been replaced by the release numbers like "5.0" and "1.4.2". Instead of "release fixed," there are now "Fixed Versions." The legacy system had many fields that could hold a sequence of text entries, including "Description," "Workaround", and "Evaluation." JIRA instead only has two analogous fields labeled as "Description" and a unified stream of "Comments." Nearly coincident with switching to JIRA, we also enabled an agent which automatically updates a JIRA issue in response to pushes into JDK-related Hg repositories. These comments include the changeset URL, the user making the push, and a time stamp. These comments are first added when a fix is pushed to a team integration repository and then added again when the fix is pushed into the master repository for a release. We're still in early days of production usage of JIRA for JDK bug tracking, but the transition to production went smoothly and over 1,000 new issues have already been filed. Many other facets of the migration are still in the works, including hosting new incidents filed at bugs.sun.com in a tailored incidents project in JIRA.

• How to Deliberately Practice Software Engineering?

  - by JasCav

  I just finished reading this recent article. It's a very interesting read, and it makes some great points. The point that specifically jumped out at me was this: The difference was in how they spent this [equal] time. The elite players were spending almost three times more hours than the average players on deliberate practice — the uncomfortable, methodical work of stretching your ability. This article (if you care not to read it) is discussing violin players. Of course, being a software engineer, my mind turned towards software ability. Granted, there are some very naturally talented individuals out there, but time and time again, it is those folks who stretch their abilities through deliberate practice that really become exceptional at their craft. My question is - how would one go about practicing the "scales" of software engineering and computer science? When I practice the piano, I will spend more of my time on scales and less on a fun song. How can I do the same in developing software? To head off early answers, I don't feel that "work on an open source project," and similar answers, is really right. Sure...that can improve your skills, but you could just as easily get stuck focusing on something that is unimportant to your craft as a whole. It can become the equivalent of learning "Twinkle Twinkle Little Star" and never being able to play Chopin. So, again, I ask - how would you suggest that someone deliberately practice software engineering?

• How can I discourage the use of Access?

  - by Greg Buehler

  Lets pretend that a very large company (revenue numbers with more than 8 figures) is looking to do a refresh on a software system, particularly the dashboard used by employees. This system was originally put together in the early 1990's to handle inventory tracking and storage across a variety of facilities (10+). Since this large company is now in the process of implementing some of these inventory processes with SAP they are in need of a major refresh. The existing system: Microsoft Access project performs dashboard duties Unique shipping/receiving configurations at different facilities require unique forms and queries within the Access project Uses 3rd party libraries referenced by Access to directly interface with at control system (read: motors, conveyors, and counters) Individual SQL Server 2000 instances (some traces of pre-update SQL Server 6.0 documents) at each facility The Issue: This system started as a home brewed inventory tracking scheme with a single internal sponsor who is still in charge of the technical direction. The original sponsor prescribing the desired deliverables that are being called for in the current RFP. The RFP describes a system based around a single Access project. Any suggestion that Access is ill suited for a project of this scope are shot down under the reasoning that "it works for the scope now". Are there any case studies, notices, or statements that can be used to disuade this potential customer from repeating their mistake? Does Microsoft make any statements directly about when it is highly recommended to ditch Access?

• JUnit Testing in Multithread Application

  - by e2bady

  This is a problem me and my team faces in almost all of the projects. Testing certain parts of the application with JUnit is not easy and you need to start early and to stick to it, but that's not the question I'm asking. The actual problem is that with n-Threads, locking, possible exceptions within the threads and shared objects the task of testing is not as simple as testing the class, but testing them under endless possible situations within threading. To be more precise, let me tell you about the design of one of our applications: When a user makes a request several threads are started that each analyse a part of the data to complete the analysis, these threads run a certain time depending on the size of the chunk of data (which are endless and of uncertain quality) to analyse, or they may fail if the data was insufficient/lacking quality. After each completed its analysis they call upon a handler which decides after each thread terminates if the collected analysis-data is sufficient to deliver an answer to the request. All of these analysers share certain parts of the applications (some parts because the instances are very big and only a certain number can be loaded into memory and those instances are reusable, some parts because they have a standing connection, where connecting takes time, ex.gr. sql connections) so locking is very common (done with reentrant-locks). While the applications runs very efficient and fast, it's not very easy to test it under real-world conditions. What we do right now is test each class and it's predefined conditions, but there are no automated tests for interlocking and synchronization, which in my opionion is not very good for quality insurances. Given this example how would you handle testing the threading, interlocking and synchronization?

• A case for not installing your own software

  - by James Gentsch

  This week I watched some of the Oracle Open World presentations (from the comfort of my Oracle office) and happened on some of Larry Ellison’s comments about cloud computing and engineered systems.  Larry said he sees the move to these as analogous to the moves made by the original adopters of electricity.  The argument goes that the first consumers of electricity had to set up their own power plant.  Then, as the market and infrastructure for electricity matured, power consumers moved from using their own personal power plant to purchasing power from another entity that was focused on power production as their primary product. In the end this was a cheaper and more reliable solution. Now, there are lots of compelling reasons to be looking very seriously at cloud computing and engineered systems for enterprise application deployment.  However, speaking as a software developer of enterprise applications, the part of this that I really love (besides Larry’s early electricity adopter analogy) is that as a mode of application deployment it provides me and my customers a consistent environment in which the applications I am providing will be run.  This cuts way down on the environmental surprises that consistently lead to the hated “well, it works here” situation with the support desk. And just to be clear, I think I hate this situation more than my clients, who I think are happy that at least it is working somewhere.  I hate this because when a problem happens, and let’s face it customers are not wasting their time calling in easy problems, we are seriously disabled when we cannot reproduce the issue which is triggered by something unforeseen in the environment where the application is running.  This situation is incredibly frustrating and an all too often occurrence. I look selfishly forward to cloud computing and engineered systems dramatically reducing the occurrence of problems triggered by unforeseen environmental situations in the software I am responsible for.  I think this is an evolutionary game changer that will be a huge benefit to the reliability and consistent performance of the software for my customers, and may make “well, it works here” a well forgotten phase for future software developers. It may even impact the stress squeeze toy industry.  Well, maybe at least for my group.

• Using prefix incremented loops in C#

  - by KChaloux

  Back when I started programming in college, a friend encouraged me to use the prefix incrementation operator ++i instead of the postfix i++, citing that there was a slight chance of better performance with no real chance of a downside. I realize this is true in C++, and it's become a general habit that I continue to do. I'm led to believe that it makes little to no difference when used in a loop in C#, regardless of data type. Apparently the ++ operator can't be overridden. Nevertheless, I like the appearance more, and don't see a direct downside to it. It did astonish a coworker just a moment ago though, he made the (fairly logical) assumption that my loop would terminate early as a result. He's a self-taught programmer, and apparently never came across the C++ convention. That made me question whether or not the equivalent behavior of pre- and post-fix increment and decrement operators in loops is well known enough. Is it acceptable for me to continue using ++i in looping constructs because of style preference, even though it has no real performance benefit? Or is it likely to cause confusion amongst other programmers? Note: This is assuming the ++i convention is used consistently throughout all code.

• Where can I find design exercises to work on?

  - by Oak

  I feel it's important to continue practicing my problem-solving skills. Writing my own mini-projects is one way, but another is to try and solve problems posted online. It's easy to find interesting programming quizzes online that require applying clever algorithms to solve - Project Euler is one well-known example. However, in a lot of real-life projects the design of the software - especially in the initial phases - has a large impact and at later stages it cannot be tweaked as easily as plain algorithms. In order to improve these skills, I'm looking for any collection of design problems. When I say "design", I mean the abstract design of a software solution - for example what modules will there be and what are the dependencies between them, how data will flow in the program, what sort of data needs to be saved in the database, etc. Design problems are those problems that are critical to solve in the early stages of any project, but their solution is a whiteboard diagram without a single line of code. Of course these sort of problems do not have a single correct solution, but I'll be especially happy with any place that also displays pros and cons of the typical solutions that might be used to approach the problem.

• Keyboard-shortcut key-press-detection sensitivity settings

  - by Juve

  last week I switched from Ubuntu 10.10 to 12.04 and after setting up my keyboard shortcuts, e.g., CTRL+ALT+E for my favorite editor and CTRL+ALT+X for the terminal, I noticed that the behavior when pressing the appropriate keys changed somehow. I know this is very subjective and I am not 100% percent sure if I am suddenly just too lazy when using my keyboard, but here is what I noticed: To run your shortcuts, you usually press the modifiers first and in addition press the alphanum key. Now, if I hold the modifiers down very consciously and press the alphanum key afterwards everything works fine. However, I noticed that I may often release the modifiers a bit too early. In Ubuntu 10.10 (metacity/compiz) my keyboard shortcuts would still execute and my tools would pop up. This does not work anymore in 12.04. Nevertheless, I still believe the old behavior to be more intuitive and would like to have it back. I a nutshell: Is there a parameter to control the shortcut-key-press detection behavior? I already searched the ubuntu keyboard options and searched for "keyboard" in gconf-editor but could not find any hints so far.

• Scheme vs Haskell for an Introduction to Functional Programming?

  - by haziz

  I am comfortable with programming in C and C#, and will explore C++ in the future. I may be interested in exploring functional programming as a different programming paradigm. I am doing this for fun, my job does not involve computer programming, and am somewhat inspired by the use of functional programming, taught fairly early, in computer science courses in college. Lambda calculus is certainly beyond my mathematical abilities, but I think I can handle functional programming. Which of Haskell or Scheme would serve as a good intro to functional programming? I use emacs as my text editor and would like to be able to configure it more easily in the future which would entail learning Emacs Lisp. My understanding, however, is that Emacs Lisp is fairly different from Scheme and is also more procedural as opposed to functional. I would likely be using "The Little Schemer" book, which I have already bought, if I pursue Scheme (seems to me a little weird from my limited leafing through it). Or would use the "Learn You a Haskell for Great Good" if I pursue Haskell. I would also watch the Intro to Haskell videos by Dr Erik Meijer on Channel 9. Any suggestions, feedback or input appreciated. Thanks. P.S. BTW I also have access to F# since I have Visual Studio 2010 which I use for C# development, but I don't think that should be my main criteria for selecting a language.

• What causes player box/world geometry glitches in old games?

  - by Alexander

  I'm looking to understand and find the terminology for what causes - or allows - players to interfere with geometry in old games. Famously, ID's Quake3 gave birth to a whole community of people breaking the physics by jumping, sliding, getting stuck and launching themselves off points in geometry. Some months ago (though I'd be darned if I can find it again!) I saw a conference held by Bungie's Vic DeLeon and a colleague in which Vic briefly discussed the issues he ran into while attempting to wrap 'collision' objects (please correct my terminology) around environment objects so that players could appear as though they were walking on organic surfaces, while not clipping through them or appear to be walking on air at certain points, due to complexities in the modeling. My aim is to compose a case study essay for University in which I can tackle this issue in games, drawing on early exploits and how techniques have changed to address such exploits and to aid in the gameplay itself. I have 3 current day example of where exploits still exist, however specifically targeting ID Software clearly shows they've massively improved their techniques between Q3 and Q4. So in summary, with your help please, I'd like to gain a slightly better understanding of this issue as a whole (its terminology mainly) so I can use terms and ask the right questions within the right contexts. In practical application, I know what it is, I know how to do it, but I don't have the benefit of level design knowledge yet and its technical widgety knick-knack terms =) Many thanks in advance AJ

• Check parameters annotated with @Nonnull for null?

  - by David Harkness

  We've begun using FindBugs with and annotating our parameters with @Nonnull appropriately, and it works great to point out bugs early in the cycle. So far we have continued checking these arguments for null using Guava's checkNotNull, but I would prefer to check for null only at the edges--places where the value can come in without having been checked for null, e.g., a SOAP request. // service layer accessible from outside public Person createPerson(@CheckForNull String name) { return new Person(Preconditions.checkNotNull(name)); } ... // internal constructor accessed only by the service layer public Person(@Nonnull String name) { this.name = Preconditions.checkNotNull(name); // remove this check? } I understand that @Nonnull does not block null values itself. However, given that FindBugs will point out anywhere a value is transferred from an unmarked field to one marked @Nonnull, can't we depend on it to catch these cases (which it does) without having to check these values for null everywhere they get passed around in the system? Am I naive to want to trust the tool and avoid these verbose checks? Bottom line: While it seems safe to remove the second null check below, is it bad practice? This question is perhaps too similar to Should one check for null if he does not expect null, but I'm asking specifically in relation to the @Nonnull annotation.

• Team Foundation Service Preview now open for all!

  - by Tarun Arora

  The concept of TFS in the cloud was first presented back in early 2010, the product team worked hard to preview a constantly evolving solution at the BUILD conference last year and after having completed 31 Sprints today the preview service has been opened for all. No more invitation codes required, TfsPreview has been made public! “Since we announced the Team Foundation Service Preview at the BUILD conference last year, we’ve limited the on boarding of new customers by requiring invitation codes to create accounts.  The main reason for this has been to control the growth of the service to make sure it didn’t run away from us and end up with a bad user experience.  In this time period, we’ve continued to work on our infrastructure, performance, scale, monitoring, management and, of course, some cool new features like cloud build. ”   - Brian Harry Since the service is still in preview, it is free for all… If you haven’t, now is the best time to try out the offering. There is no fixed time line on how long before service becomes chargeable but the terms of service support production use, the service is reliable and the product team committed to carry all of your data forward into production. “The service will remain in “preview” for a while longer while we work through additional features like data portability, commercial terms, etc but the terms of service support production use, the service is reliable and we expect to carry all of your data forward into production. ”  - Brian Harry As of today it’s possible to use TFS Preview with VS 2012 RC, VS 2010 SP1, VS 2008 SP1, the service currently does not work with VS 2005, this is something the product team is actively working on. You can refer to Brian’s announcement blog post here, http://blogs.msdn.com/b/bharry/archive/2012/06/11/team-foundation-service-preview-is-public.aspx
