  • What is the best database design and/or software to model a thesaurus?

    - by Miles O'Keefe
    I would like to design a web app that functions as a simple thesaurus : a long list of words with attributes, all of which are linked to each other. Wikipedia defines it as: In Information Science, Library Science, and Information Technology, specialized thesauri are designed for information retrieval. They are a type of controlled vocabulary, for indexing or tagging purposes. Such a thesaurus can be used as the basis of an index for online material. The Art and Architecture Thesaurus, for example, is used to index the Canadian Information retrieval thesauri are formally organized so that existing relationships between concepts are made explicit. What database software, design or model would best fit this? Are PHP and MySQL good technologies to handle it?

  • ASP.NET MVC: Converting business objects to select list items

    - by DigiMortal
    Some of our business classes are used to fill dropdown boxes or select lists. And often you have some base class for all your business classes. In this posting I will show you how to use base business class to write extension method that converts collection of business objects to ASP.NET MVC select list items without writing a lot of code. BusinessBase, BaseEntity and other base classes I prefer to have some base class for all my business classes so I can easily use them regardless of their type in contexts I need. NB! Some guys say that it is good idea to have base class for all your business classes and they also suggest you to have mappings done same way in database. Other guys say that it is good to have base class but you don’t have to have one master table in database that contains identities of all your business objects. It is up to you how and what you prefer to do but whatever you do – think and analyze first, please. :) To keep things maximally simple I will use very primitive base class in this example. This class has only Id property and that’s it. public class BaseEntity {     public virtual long Id { get; set; } } Now we have Id in base class and we have one more question to solve – how to better visualize our business objects? To users ID is not enough, they want something more informative. We can define some abstract property that all classes must implement. But there is also another option we can use – overriding ToString() method in our business classes. public class Product : BaseEntity {     public virtual string SKU { get; set; }     public virtual string Name { get; set; }       public override string ToString()     {         if (string.IsNullOrEmpty(Name))             return base.ToString();           return Name;     } } Although you can add more functionality and properties to your base class we are at point where we have what we needed: identity and human readable presentation of business objects. Writing list items converter Now we can write method that creates list items for us. public static class BaseEntityExtensions {            public static IEnumerable<SelectListItem> ToSelectListItems<T>         (this IList<T> baseEntities) where T : BaseEntity     {         return ToSelectListItems((IEnumerator<BaseEntity>)                    baseEntities.GetEnumerator());     }       public static IEnumerable<SelectListItem> ToSelectListItems         (this IEnumerator<BaseEntity> baseEntities)     {         var items = new HashSet<SelectListItem>();           while (baseEntities.MoveNext())         {             var item = new SelectListItem();             var entity = baseEntities.Current;               item.Value = entity.Id.ToString();             item.Text = entity.ToString();               items.Add(item);         }           return items;     } } You can see here to overloads of same method. One works with List<T> and the other with IEnumerator<BaseEntity>. Although mostly my repositories return IList<T> when querying data there are always situations where I can use more abstract types and interfaces. Using extension methods in code In your code you can use ToSelectListItems() extension methods like shown on following code fragment. ... var model = new MyFormModel(); model.Statuses = _myRepository.ListStatuses().ToSelectListItems(); ... You can call this method on all your business classes that extend your base entity. Wanna have some fun with this code? Write overload for extension method that accepts selected item ID.

  • My Tech Ed North America Preview - Content Edition

    - by Chris Gardner
    As I promised in my last post, I feel the need to give you a rundown on all the technical content I am looking forward to checking out at Tech Ed this year. We shall start with the content I know I'll be able to see. This would be some demo stations in the Technical Learning Center. I will DEFINITELY be checking out the Windows Phone Device Bar. I will admit that I am a bit of a phone snob, and I just want to manhandle all that sexy, sexy tech. I am also planning on talking to the Windows Phone team and the Azure team. Year after year, I end up spending more time in either the TLC or taking certification tests than anywhere else. This leads me to the one "Exam Cram" session I hope to attend. There is a session to cram for 70-599: Designing and Developing Windows Phone Applications. I know this seems odd. I'm (sort of) an XNA guru. However, I'm not that up on my Silverlight. I know enough to add Silverlight to an XNA project. Now, let's talk breakout sessions. We always need to keep track of where we're going. I know, I talk about solving problems over forcing buzz words. However, it is important to know what those buzz words before you tell people not to use them. For this, we will look to the "What's New in Visual Studio 11" and "What's New in Microsoft .NET Framework 4.5." Of course, we do talk bad about buzz words around here. For this, I'm really looking forward to "Visual C#/Visual Basic: Becoming a Guru with Existing Features." I still have .NET 2 tricks that are crucial to my internal libraries. In depth knowledge will NEVER trump shortcut libraries. There is a session in ASP.NET for phones and tablets. For those of you that have not tried to use ASP.NET on a mobile device, there is one thing you really need to understand. Mobile devices don't use scroll bars. That's right; the thing with the least screen real estate doesn't use scroll bars. Thus, I am hoping this session will give some good advice in having an ASP.NET site target both mobile and desktop. The last "business only" session "The Accidental Team Foundation Server Admin." T & W Operations is a VERY small business. As such, I am the TFS admin because I'm the developer that is also the SQL Guru. I keep my server up, but it'd be nice to know some really cool tricks for the part time guy. This leads us the the fun sessions. Coding4Fun has a Kinect session. The Twitter followers will remember that I now have a Kinect for Windows sitting on my desk at work. I have gotten pretty handy with the device, but I KNOW I'm missing some good stuff. Finally, we come to Brian Prince's session on "Making Crazy Money with Games and the Cloud." Never mind the fact that we're using Azure at work. Never mind the fact that I'm actually using the cloud in a game. Never mind the fact that the session has the terms "Crazy Money" and "Games" in the title. If you've never seen Brian Prince speak, you're missing out. In the Hands-on-Labs, we are not allowed to make our own schedule. Instead, we're asked what sessions we can't miss, and they try to schedule around those times. This was the one session I said I couldn't miss. This should complete the technical content for the conference. Coming soon, I'll dig into the certifications I hope to attain. Then, we'll talk about the social activities for the week. Here's a preview of that. I am a member of The Krewe...

  • Web-based CMS for mobile app

    - by JWood
    I'm just about to start developing a mobile app which needs to be fed from a CMS. I started designing the tables when I thought there must be something out there which could save me a load of time and let me concentrate on the mobile side of things. So, I'm looking for a CMS that will let me create hierarchical "pages" which will just be 4-5 database fields with a simple front-end to allow to edit and update them. I don't mind having to write some code to layout the database and forms etc, any saving on starting from scratch would be good. The only requirement is that I be able to access the data via some sort of web service, REST, JSON, XML, anything really... Can anyone suggest anything that might help? Thanks, J

  • Regular Expressions. Remember it, write it, test it.

    - by outcoldman
    I should say that I’m fan of regular expressions. Whenever I see the problem, which I can solve with Regex, I felt a burning desire to do it and going to write new test for new regex. Previously I had installed SharpDevelop Studio just for good regular expression tool in it (Why VS doesn’t have one?). But now I’m a little wiser, and for each Regex I write a separate test. I find it difficult to remember the syntax of regular expressions (I don’t write them very often); I always forget which character is responsible for the beginning of the line, etc. So I use external small and easy articles like this “Regular expressions - An introduction”. Now I want to show you little samples of regular expressions and want to show you how to test these samples. Read more... (redirect to http://outcoldman.ru)

  • wordpress.com to self-hosted wordpress blog

    - by sAc
    Hello, I have been writing articles on the wordpress.com blog, now i am looking to move it to self-hosted wordpress blog but i wonder: 1) Should i move all my articles on the new blog or just put an article on my last blog that more articles will be posted on my new blog? 2) If i move all articles on my new blog, i am not sure about how google will react to it because there are articles with good number of visitors, won't this be seo-un-friendly because i am not sure but google will re-create page reputation stuff, etc or those articles will have same popularity even if i move elsewhere? 3) What are the implications and side-effects in moving from wordpress.com blog to self-hosted wordpress blog?

  • How to be more logical? (less bugs/errors)

    - by SamB
    I have been programming for 6 years and I am in high school (I prefer not to disclose my age). I have dabbled in many different languages. Just to list a few: Java, PHP, C++, Python, Autohotkey, Mathematica and many more. I have a very good understanding of the basics of general programming. The only problem is I still create bugs all the time. I think too often. Do you have any hints besides continuing to program that will help me become a better programmer and make less errors?

  • Initial Review - Mastering Unreal Technology I: Introduction to Level Design with Unreal Engine 3

    - by Matt Christian
    Recently I purchased 3 large volumes on using the Unreal 3 Engine to create levels and custom games.  This past weekend I cracked the spine of the first and started reading.  Here are my early impressions (I'm ~250 pages into it, with appendices it's about 900). Pros Interestingly, the book starts with an overview of the Unreal engines leading up to Unreal 3 (including Gears of War) and follows with some discussion on planning a mod and what goes into the game development process.  This is nice for an intro to the book and is much preferred rather than a simple chapter detailing what is on the included CD, how to install and setup UnrealEd, etc...  While the chapter on Unreal history and planning can be considered 'fluff', it's much less 'fluffy' than most books provide. I need to mention one thing here that is pretty crucial in the way I'm going to continue reviewing this book.  Most technical books like this are used as a shelf reference; as a thick volume you use for looking up techniques every now and again.  Even so, I prefer reading from cover to cover, including chapters I may already be knowledgable on (I'm sure this is typical for most people).  If there was a chapter on installing UnrealEd (the previously mentioned 'fluff'), I would probably force myself to read it, even though I've installed the game and engine multiple times on different systems. Chapter 3 is where we really get to the introduction piece of UnrealEd, creating your first basic level.  This large chapter details creating two small rooms, adding static meshes, adding lighting, creating and adding particle emitters, creating a door that animates with Unreal Matinee and Kismet, static meshes with physics, and other little additions to make your level look less beginner.  This really is a chapter that overviews the entire rest of the book, as each chapter following details the creation and intermediate usages of Static Meshes, Materials, Lighting, etc... One other very nice part to this book is the way the tutorials are setup.  Each tutorial builds off the previous and all are step-by-step.  If you haven't completed one yet, you can find all the starting files on the CD that comes with the book. Cons While the description of the overview chapter (Chapter 3) is fresh in your mind, let me start the cons by saying this chapter is setup extremely confusing for the noob.  At one point, you end up creating a door mesh and setting it up as a InteropMesh so that it is ready to be animated, only to switch to particles and spend a good portion of time working on a different piece of the level.  Yes, this is actually how I develop my levels (jumping back and forth), though it's very odd for a book to jump out of sequence. The next item might be a positive or a negative depending on your skill level with UnrealEd.  Most of the introduction to the editor layout is found in one of the Appendices instead of before Chapter 3.  For new readers, this might lead to confusion as Appendix A would typically be read between Chapter 2 and 3.  However, this is a positive for those with some experience in UnrealEd as they don't have to force themselves through a 'learn every editor button' chapter.  I'm listing this in the Cons section as the book is 'Introduction to...' and is probably going to be directed toward a lot of very beginner developers. Finally, there's a lack of general description to a lot of the underlying engine and what each piece in UnrealEd is or does.  Sometimes you'll be performing Tutorial after Tutorial with barely a paragraph in between describing ANY of what you've just done.  Tutorial 1.1 Step 6 says to press Button X, so you do.  But why?  This is in part a problem with the structure of the tutorials rather than the content of the book.  Since the tutorials are so focused on a step-by-step (or procedural) description of a process, you learn the process and not why you're doing that.  For example, you might learn how to size a material to a surface, but will only learn what buttons to press and not what each one does. This becomes extremely apparent in the chapter on Static Meshes as most of the chapter is spent in 3D Studio Max.  Since there are books on 3DSM and modelling, the book really only tells you the steps and says to go grab a book on modelling if you're really interested in 3DSM.  Again, I've learned the process to develop my own meshes in 3DSM, but I don't know the why behind the steps. Conclusion So far the book is very good though I would have a hard time recommending it to a complete beginner.  I would suggest anyone looking at this book (obviously including the other 2, more advanced volumes) to pick up a copy of UDK or Unreal 3 (available online or via download services such as Steam) and watch some online tutorials and play with it first.  You'll find plenty of online videos available that were created by the authors and may suit as a better introduction to the editor.

  • Ubuntu Touch porting: bad file tree

    - by fcole90
    I'm trying to port ubuntu touch to Samsung Galaxy S Plus but I'm finding it really difficult. The problems at first were to find a good CM rom as base, because this device is not officially supported by CM. Currently I'm using EhndroixIII but now I'm founding a lot of problems with the porting guide. In particular my file tree seems totally different from the one of the guide. For example, there is no device folder. What can I do to solve? Should I create those files? My repository is https://github.com/fcole90/utouch-sgsp.git

  • Display date/time in Ubuntu lock screen (cinnamon-like)

    - by 3l4ng
    I was using Ubuntu 13.04 till a few days ago. I had installed Nemo and I guess cinnamon got installed too (I was still using Unity nonetheless). One of the good things about that was the lock screen somehow changed to mimick cinnamon's (with the background as a darkened version of desktop background and date/time displayed), something like this: I have no idea how this happened, but it looked great. It does not seem to work on Ubuntu 13.10. Anyone has any ideas to get a similar lock screen? I just need to display the date/time on one side with the bg as a darkened version of my desktop wallpaper

  • Tokenizing JavaScript: A look at what’s left after minification

    - by InfinitiesLoop
    Minifiers JavaScript minifiers are popular these days. Closure , YUI Compressor , Microsoft Ajax Minifier , to name a few. Using one is essential for any site that uses more than a little script and cares about performance. Each tool of course has advantages and disadvantages. But they all do a pretty good job. The results vary only slightly in the grand scheme of things. Not enough to make so much of a difference that I’d say you should always use one over the other – use whatever fits in with your...(read more)

  • ATI proprietary driver performance?

    - by Axel
    I'm about to (at least, want to..) buy a laptop with an ATI Radeon HD 4250, and I haven't a good opinion on ATI's drivers. How is the actual performance of the open/proprietary driver (currently I have nVidia, and I'm very satisfied)? The intended use for the laptop is: watching videos, programming in Java/PHP/maybe Qt... but, I like to know if Compiz runs well. Yes, I'm a hardcore (?) programmer that uses Compiz. :P Someone has this GPU? Experiences? Thoughts? Thanks! :D

  • A Rose by Any Other Name..

    - by Geoff N. Hiten
    It is always a good start when you can steal a title line from one of the best writers in the English language.  Let’s hope I can make the rest of this post live up to the opening.  One recurring problem with SQL server is moving databases to new servers.  Client applications use a variety of ways to resolve SQL Server names, some of which are not changed easily <cough SharePoint /cough>.  If you happen to be using default instances on both the source and target SQL Server, then the solution is pretty simple.  You create (or bug the network admin until she creates) two DNS “A” records. One points the old name to the new IP address.  The other creates a new alias for the old server, since the original system name is now redirected.  Note this will redirect ALL traffic from the old server to the new server, including RDP and file share connection attempts.    Figure 1 – Microsoft DNS MMC Snap-In   Figure 2 – DNS New Host Dialog Box Both records are necessary so you can still access the old server via an alternate name. Server Role IP Address Name Alias Source 10.97.230.60 SQL01 SQL01_Old Target 10.97.230.80 SQL02 SQL01 Table 1 – Alias List If you or somebody set up connections via IP address, you deserve to have to go to each app and fix it by hand.  That is the only way to fix that particular foul-up. If have to deal with Named Instances either as a source or a target, then it gets more complicated.  The standard fix is to use the SQL Server Configuration Manager (or one of its earlier incarnations) to create a SQL client alias to redirect the connection.  This can be a pain installing and configuring the app on multiple client servers.  The good news is that SQL Server Configuration Manager AND all of its earlier versions simply write a few registry keys.  Extracting the keys into a .reg file makes centralized automated deployment a snap. If the client is a 32-bit system, you have to extract the native key.  If it is a 64-bit, you have to extract the native key and the WoW (32 bit on 64 bit host) key. First, pick a development system to create the actual registry key.  If you do this repeatedly, you can simply edit an existing registry file.  Create the entry using the SQL Configuration Manager.  You must use a 64-bit system to create the WoW key.  The following example redirects from a named instance “SQL01\SQLUtiluty” to a default instance on “SQL02”.   Figure 3 – SQL Server Configuration Manager - Native Figure 3 shows the native key listing. Figure 4 – SQL Server Configuration Manager – WoW If you think you don’t need the WoW key because your app is 64 it, think again.  SQL Server Management Server is a 32-bit app, as are most SQL test utilities.  Always create both keys for 64-bit target systems. Now that the keys exist, we can extract them into a .reg file. Fire up REGEDIT and browse to the following location:  HKLM\Software\Microsoft\MSSQLServer\Client\ConnectTo.  You can also search the registry for the string value of one of the server names (old or new). Right click on the “ConnectTo” label and choose “Export”.  Save with an appropriate name and location.  The resulting file should look something like this: Figure 5 – SQL01_Alias.reg Repeat the process with the location: HKLM\Software\Wow6432Node\Microsoft\MSSQLServer\Client\ConnectTo Note that if you have multiple alias entries, ALL of the entries will be exported.  In that case, you can edit the file and remove the extra aliases. You can edit the files together into a single file.  Just leave a blank line between new keys like this: Figure 6 – SQL01_Alias_All.reg Of course if you have an automatic way to deploy, it makes sense to have an automatic way to Un-deploy.  To delete a registry key, simply edit the .reg file and replace the target with a “-“ sign like so. Figure 7 – SQL01_Alias_UNDO.reg Now we have the ability to move any database to any server without having to install or change any applications on any client server.  The whole process should be transparent to the applications, which makes planning and coordinating database moves a far simpler task.

  • Essential management tools for a small/medium software development shop

    - by mikera
    I've recently started work with an organisation that is rapidly expanding and is recruiting or growing several development teams (including two web-based products and a data warehouse/BI team). They are basically working to agile methodologies but haven't formalised a standard way of working yet. Despite the fact that it is early days, I've been surprised by the lack of tools being used to manage the development processes (e.g. no issue tracker, no tool to manage the product backlog etc.) Although it's not my primary responsibility, I'd like to help them out with some recommendations on the most important tools they should get in place. What are the 3-5 top priority tools to establish for management of a good development shop? Why are they necessary? How do they improve the software development process, and how do I justify them to my bosses?

  • SQL Developer Data Modeler v3.3 Early Adopter: Collaborative Design via Excel?

    - by thatjeffsmith
    As you may have heard last week, we have a new version of Oracle SQL Developer Data Modeler now available as an Early Adopter release. Version 3.3 has quite a few new features and I’ll be previewing them here. Today’s topic is our new Excel integration. It builds off of last week’s lesson: Search, so you may want to go read that first. They say it takes a village to raise a child. I say it takes a team to build a data model. You have your techie folks, your business folks, your in-betweeners, and your database geeks. Who gets to define how customers are represented and stored in your database? That data lives forever, so you better get it right from the beginning, or you’ll be living in a hacker’s paradise for years to come. Lots of good rantings, ravings, and advice on this topic in general on Karen Lopez’s (@datachick) blog. But let’s say you are the primary modeler on a project. You dutifully interview the business folks for their requirements. You sit down and start to model and think you’re pretty close. Now you need someone to confirm your assumptions and provide some feedback. Do you send your model over? Take a screenshot and blow it up on a whiteboard? Export to HTML and let them take a magic marker to their monitors? Or maybe you bite the bullet and install your modeling software on their desktops and take the hours or days required to train them up on how to use the the tool. Wouldn’t it be nice if they could just mark up their corrections in Excel and let you suck the updates back in? This is what we have started to build in Oracle SQL Developer Data Modeler. Let’s say you have a new table called ‘UT_STARTUPS.’ It looks a little something like this: A table in Oracle SQL Developer Data Modeler What I would like to do is have my team or co-worker review how I have defined those columns. Perhaps TIMESTAMP is overkill or maybe the column names themselves aren’t up to snuff. What I am going to do is now search for all the columns in my table, then export that to Excel. So do a search for UT_STARTUPS. Search, filter, then Report With the filter set to ‘Columns,’ if I do a report I’ll be only getting the columns that are resolving to my search term. So as long as my table name is unique in the model, I should get what I’m looking for. Here’s what I see when I click on the Report button: XLS or XLSX, either format is just fine I want to decide how the Column data is exported to Excel though, so I’m going to create a report template that I can use going forward. So click the ‘Manage’ button and setup a new template. I’m going to call mine ‘CollaborativeDevelopment.’ The templates allow me to define what properties are included in the reports. Once this is set, I’ll have the XLS file generated, and get to work Now let the Excel junkies do their stuff Note that not ALL of the report properties are update-able (yes, I made up a new word there) via Excel. We’ll have the full list of properties documented going forward, but in my Excel sheet, note that I can’t change the table name or the data types for the columns. I’m going to update some column names and supply ‘nice’ comments so the database users know what’s what. Here’s my input for the designer/architect/database dude: Be kind, please rew…use comments. Save the file, email it back to your modeler. Update the model from Excel That’s right, it’s a right mouse click from your model in the tree If everything goes right, you’ll see a nice confirmation message: It’s alive! Another to-do item on tap – making this dialog more informative. We’ll be showing exactly what in your model was updated from Excel. Let’s take another look at the model now Voila! Why are we doing this again? The goal is to reduce the number of round-trips from the modeler and the business process owner. One is used to working with Excel – why not allow them to mark up their changes in the tool they already know? This is an early adopter release and I anticipate this feature getting a good bit of tuning up before we release. Why don’t you download 3.3, give it a whirl, and let us know what you think?

  • I Didn&rsquo;t Get You Anything&hellip;

    - by Bob Rhubart
    Nearly every day this blog features a  list posts and articles written by members of the OTN architect community. But with Christmas just days away, I thought a break in that routine was in order. After all, if the holidays aren’t excuse enough for an off-topic post, then the terrorists have won. Rather than buy gifts for everyone -- which, given the readership of this blog and my budget could amount to a cash outlay of upwards of $15.00 – I thought I’d share a bit of holiday humor. I wrote the following essay back in the mid-90s, for a “print” publication that used “paper” as a content delivery system.  That was then. I’m older now, my kids are older, but my feelings toward the holidays haven’t changed… It’s New, It’s Improved, It’s Christmas! The holidays are a time of rituals. Some of these, like the shopping, the music, the decorations, and the food, are comforting in their predictability. Other rituals, like the shopping, the  music, the decorations, and the food, can leave you curled into the fetal position in some dark corner, whimpering. How you react to these various rituals depends a lot on your general disposition and credit card balance. I, for one, love Christmas. But there is one Christmas ritual that really tangles my tinsel: the seasonal editorializing about how our modern celebration of the holidays pales in comparison to that of Christmas past. It's not that the old notions of how to celebrate the holidays aren't all cozy and romantic--you can't watch marathon broadcasts of "It's A Wonderful White Christmas Carol On Thirty-Fourth Street Story" without a nostalgic teardrop or two falling onto your plate of Christmas nachos. It's just that the loudest cheerleaders for "old-fashioned" holiday celebrations overlook the fact that way-back-when those people didn't have the option of doing it any other way. Dashing through the snow in a one-horse open sleigh? No thanks. When Christmas morning rolls around, I'm going to be mighty grateful that the family is going to hop into a nice warm Toyota for the ride over to grandma's place. I figure a horse-drawn sleigh is big fun for maybe fifteen minutes. After that you’re going to want Old Dobbin to haul ass back to someplace warm where the egg nog is spiked and the family can gather in the flickering glow of a giant TV and contemplate the true meaning of football. Chestnuts roasting on an open fire? Sorry, no fireplace. We've got a furnace for heat, and stuffing nuts in there voids the warranty. Any of the roasting we do these days is in the microwave, and I'm pretty sure that if you put chestnuts in the microwave they would become little yuletide hand grenades. Although, if you've got a snoot full of Yule grog, watching chestnuts explode in your microwave might be a real holiday hoot. Some people may see microwave ovens as a symptom of creeping non-traditional holiday-ism. But I'll bet you that if there were microwave ovens around in Charles Dickens' day, the Cratchits wouldn't have had to entertain an uncharacteristically giddy Scrooge for six or seven hours while the goose cooked. Holiday entertaining is, in fact, the one area that even the most severe critic of modern practices would have to admit has not changed since Tim was Tiny. A good holiday celebration, then as now, involves lots of food, free-flowing drink, and a gathering of friends and family, some of whom you are about as happy to see as a subpoena. Just as the Cratchit's Christmas was spent with a man who, for all they knew, had suffered some kind of head trauma, so the modern holiday gathering includes relatives or acquaintances who, because they watch too many talk shows, and/or have poor personal hygiene, and/or fail to maintain scheduled medication, you would normally avoid like a plate of frosted botulism. But in the season of good will towards men, you smile warmly at the mystery uncle wandering around half-crocked with a clump of mistletoe dangling from the bill of his N.R.A. cap. Dickens' story wouldn't have become the holiday classic it has if, having spotted on their doorstep an insanely grinning, raw poultry-bearing, fresh-off-a-rough-night Scrooge, the Cratchits had pulled their shades and pretended not to be home. Which is probably what I would have done. Instead, knowing full well his reputation as a career grouch, they welcomed him into their home, and we have a touching story that teaches a valuable lesson about how the Christmas spirit can get the boss to pump up the payroll. Despite what the critics might say, our modern Christmas isn't all that different from those of long ago. Sure, the technology has changed, but that just means a bigger, brighter, louder Christmas, with lasers and holograms and stuff. It's our modern celebration of a season that even the least spiritual among us recognizes as a time of hope that the nutcases of the world will wake up and realize that peace on earth is a win/win proposition for everybody. If Christmas has changed, it's for the better. We should continue making Christmas bigger and louder and shinier until everybody gets it.  *** Happy Holidays, everyone!   del.icio.us Tags: holiday,humor Technorati Tags: holiday,humor

  • libimobiledevice wants to remove all my other packages

    - by Dror Cohen
    When running the command sudo apt-get remove libimobiledevice2 I get: The following packages will be REMOVED: ... gdm gdm-guest-session gnome-power-manager gnome-session gnome-session-bin gvfs-backends indicator-power indicator-session kde-plasma-desktop kde-standard libgpod-common libgpod4 libimobiledevice2 nautilus-share ubuntu-desktop upower` Is it really nessecary to remove all of my KDE and Gnome packages? The source of the problem is that the installed oneric package doesn't recognize my ios 5.1 - so I wanted to switch to the latest and greatest (1.0.7 and if that's not good enough I'll go to the dev version 1.1.2). I'm using oneric 64bit.

  • Examples of continuous integration workflow using git

    - by Andrew Barinov
    Can anyone provide a rough outline of their git workflow that complies with continuous integration. E.g. How do you branch? Do you fast forward commits to the master branch? I am primarily working with Rails as well as client and server side Javascript. If anyone can recommend a solid CI technology that's compatible with those, that'd be great. I've looked into Jenkins but would like to check out other good alternatives. To put some context into this, I am planning on transitioning from working as a single developer into working as part of the team. I'd like to start standardizing my own personal workflow so that I can onboard new devs quickly.

  • Talking JavaOne with Rock Star Martijn Verburg

    - by Janice J. Heiss
    JavaOne Rock Stars, conceived in 2005, are the top-rated speakers at each JavaOne Conference. They are awarded by their peers, who, through conference surveys, recognize them for their outstanding sessions and speaking ability. Over the years many of the world’s leading Java developers have been so recognized. Martijn Verburg has, in recent years, established himself as an important mover and shaker in the Java community. His “Diabolical Developer” session at the JavaOne 2011 Conference got people’s attention by identifying some of the worst practices Java developers are prone to engage in. Among other things, he is co-leader and organizer of the thriving London Java User Group (JUG) which has more than 2,500 members, co-represents the London JUG on the Executive Committee of the Java Community Process, and leads the global effort for the Java User Group “Adopt a JSR” and “Adopt OpenJDK” programs. Career highlights include overhauling technology stacks and SDLC practices at Mizuho International, mentoring Oracle on technical community management, and running off shore development teams for AIG. He is currently CTO at jClarity, a start-up focusing on automating optimization for Java/JVM related technologies, and Product Advisor at ZeroTurnaround. He co-authored, with Ben Evans, "The Well-Grounded Java Developer" published by Manning and, as a leading authority on technical team optimization, he is in high demand at major software conferences.Verburg is participating in five sessions, a busy man indeed. Here they are: CON6152 - Modern Software Development Antipatterns (with Ben Evans) UGF10434 - JCP and OpenJDK: Using the JUGs’ “Adopt” Programs in Your Group (with Csaba Toth) BOF4047 - OpenJDK Building and Testing: Case Study—Java User Group OpenJDK Bugathon (with Ben Evans and Cecilia Borg) BOF6283 - 101 Ways to Improve Java: Why Developer Participation Matters (with Bruno Souza and Heather Vancura-Chilson) HOL6500 - Finding and Solving Java Deadlocks (with Heinz Kabutz, Kirk Pepperdine, Ellen Kraffmiller and Henri Tremblay) When I asked Verburg about the biggest mistakes Java developers tend to make, he listed three: A lack of communication -- Software development is far more a social activity than a technical one; most projects fail because of communication issues and social dynamics, not because of a bad technical decision. Sadly, many developers never learn this lesson. No source control -- Developers simply storing code in local filesystems and emailing code in order to integrate Design-driven Design -- The need for some developers to cram every design pattern from the Gang of Four (GoF) book into their source code All of which raises the question: If these practices are so bad, why do developers engage in them? “I've seen a wide gamut of reasons,” said Verburg, who lists them as: * They were never taught at high school/university that their bad habits were harmful.* They weren't mentored in their first professional roles.* They've lost passion for their craft.* They're being deliberately malicious!* They think software development is a technical activity and not a social one.* They think that they'll be able to tidy it up later.A couple of key confusions and misconceptions beset Java developers, according to Verburg. “With Java and the JVM in particular I've seen a couple of trends,” he remarked. “One is that developers think that the JVM is a magic box that will clean up their memory, make their code run fast, as well as make them cups of coffee. The JVM does help in a lot of cases, but bad code can and will still lead to terrible results! The other trend is to try and force Java (the language) to do something it's not very good at, such as rapid web development. So you get a proliferation of overly complex frameworks, libraries and techniques trying to get around the fact that Java is a monolithic, statically typed, compiled, OO environment. It's not a Golden Hammer!”I asked him about the keys to running a good Java User Group. “You need to have a ‘Why,’” he observed. “Many user groups know what they do (typically, events) and how they do it (the logistics), but what really drives users to join your group and to stay is to give them a purpose. For example, within the LJC we constantly talk about the ‘Why,’ which in our case is several whys:* Re-ignite the passion that developers have for their craft* Raise the bar of Java developers in London* We want developers to have a voice in deciding the future of Java* We want to inspire the next generation of tech leaders* To bring the disparate tech groups in London together* So we could learn from each other* We believe that the Java ecosystem forms a cornerstone of our society today -- we want to protect that for the futureLooking ahead to Java 8 Verburg expressed excitement about Lambdas. “I cannot wait for Lambdas,” he enthused. “Brian Goetz and his group are doing a great job, especially given some of the backwards compatibility that they have to maintain. It's going to remove a lot of boiler plate and yet maintain readability, plus enable massive scaling.”Check out Martijn Verburg at JavaOne if you get a chance, and, stay tuned for a longer interview yours truly did with Martijn to be publish on otn/java some time after JavaOne.

  • Universal navigation menu across domains - would it be considered duplicate content?

    - by Jon Harley
    Across different sites on different second-level domains exists a universal navigation bar with a collection of roughly 30 links. This universal bar is exactly the same for every page on each domain. The bar's HTML, CSS and JavaScript are all stored in a subfolder for each domain and the HTML is embedded upon serving the page and is not being injected on the client side. None of the links use any rel directives and are as vanilla as can be. My question is about Google's duplicate content rule. Would something like this be considered duplicate content? Matt Cutt's blog post about duplicate content mentions boilerplate repetition, but then he mentions lengthy legalese. Since the text in this universal bar is brief and uses common terms, I wonder if this same rule applies. If this is considered duplicate content, what would be a good way to correct the problem?
