• Misadventures at Radio Shack

  - by Chris Williams

  While I'm waiting for my Arduino kits to show up, I started reading the Getting Started With Arduino book from O'Reilly (review coming later) and I'm about 40 pages in when I get to a parts list for one of the first projects. Looks pretty straightforward, and even has Radio Shack part numbers next to almost everything. So on my lunch today, I decided to run out to "The Shack" (seriously, that's their rebranding?) to pick up some basics, like a couple resistors, a breadboard, a momentary switch and a pack of pre-cut jumper wires. I found the resistors without any difficulty, and while they didn't have the exact switch I wanted, it was easy enough to find one that would do. That's where my good luck abruptly ended. I was surprised that I couldn't find a breadboard or any jumper wires, so while I was looking around, a guy came up and asked me if I needed some help. I told him I did, explained what I needed and even gave him the Radio Shack part number for the pack of jumper wires. After a couple minutes he says he can't find anything in the system, which was unfortunate but not the end of the world.  So then I asked him about the breadboard, and he pointed me to some blank circuitboards (which are not the same thing) and I said (nicely) that those weren't breadboards and attempted to explain (again) what I needed, at which point he says to me "I don't even know what the hell you're looking for!" I stood there for a moment and tried to process his words. About that time, another salesperson came up and asked what I was trying to find. I told her I needed a breadboard, and she pointed to the blank circuit boards and said "they're right in front of you..." After seeing the look on my face, she thought for a minute and said... "OH! you mean those white things. We don't have those anymore." I thanked her, set everything down on the counter and left. (I wasn't going to buy only half the stuff I needed.. and I was pretty sure I was never going to be buying ANYTHING at that particular location ever again.) Guess I'll be ordering more stuff online at this point. It's a shame really, because I used to LOVE going to Radio Shack as a kid, and looking through all the cool electronics components and stuff, even if I didnt understand what most of them were at the time. Seems like the only thing they carry in any quantity/variety now is cell phones and random stereo connectors.

• Less Can Be More In E-Commerce

  - by Michael Hylton

  Today’s consumers are inundated with product choices and vendors. Visit your favorite electronics retailer and see the vast assortment of flat panel televisions. Or the variety of detergents at the supermarket. All of this can be daunting for the average consumer who is looking for the products and services that interest them.  In a study titled “Choice is Demotivating: Can One Desire Too Much of a Good Thing”, the author, Sheena Iyengar found that participants actually reported greater subsequent satisfaction with their selections and wrote better essays when their original set of options had been limited. The same can be said for e-commerce and your website. Being able to quickly convert shoppers into buyers with effective merchandising is what makes leading businesses successful. You want to engage each individual visitor with the most-relevant content to drive higher conversions and order values while decreasing abandonment, but predicting what will resonate with each customer is difficult. In a world of choices, online merchandizing tools can help personalize, streamline, and refine what your customers view when they browse your online catalog. The key to being effective is to align your products and content as closely as possible with the customer’s needs. The goal on the home page is to promote your brand and push visitors farther into the site. The home page is often the starting point for repeat customers as well as for new visitors hoping to address their current product needs. As the customer selects different filters and narrows the choices, valuable information is being provided to the retailer about the customer’s current need—regardless of previous search behavior or what other customers with a similar demographic profile have purchased. Together with search pages, category browse pages are among the primary options available to customers as a means of finding products on your site. Once a customer reaches the product detail page, it is clear what that person desires, regardless of the segment the customer falls into. However, don’t disregard campaign-based promotions completely. A campaign targeted to all customers but featuring rule-driven promotions tied to the product can be effective.

• Best Creational Pattern for loggers in a multi-threaded system?

  - by Dipan Mehta

  This is a follow up question on my past questions : Concurrency pattern of logger in multithreaded application As suggested by others, I am putting this question separately. As the learning from the last question. In a multi-threaded environment, the logger should be made thread safe and probably asynchronous (where in messages are queued while a background thread does writing releasing the requesting object thread). The logger could be signleton or it can be a per-group logger which is a generalization of the above. Now, the question that arise is how does logger should be assigned to the object? There are two options I can think of: 1. Object requesting for the logger: Should each of the object call some global API such as get_logger()? Such an API returns "the" singleton or the group logger. However, I feel this involves assumption about the Application environment to implement the logger -which I think is some kind of coupling. If the same object needs to be used by other application - this new application also need to implement such a method. 2. Assign logger through some known API The other alternative approach is to create a kind of virtual class which is implemented by application based on App's own structure and assign the object sometime in the constructor. This is more generalized method. Unfortunately, when there are so many objects - and rather a tree of objects passing on the logger objects to each level is quite messy. My question is there a better way to do this? If you need to pick any one of the above, which approach is would you pick and why? Other questions remain open about how to configure them: How do objects' names or ID are assigned so that will be used for printing on the log messages (as the module names) How do these objects find the appropriate properties (such as log levels, and other such parameters) In the first approach, the central API needs to deal with all this varieties. In the second approach - there needs to be additional work. Hence, I want to understand from the real experience of people, as to how to write logger effectively in such an environment.

• NVIDIA 550M Drivers

  - by DOOM

  First to say, I am newbie, to the linux world and in situation where i have to get used to using ubuntu. My system is: i7-2630QM 8GB Ram with 750GB HD + NVIDIa 550M (1GB) Since i was facing problems with wubi - "slow Ubuntu", i installed it on a separate partition, of 80GB (10GB Swap, 40GB HOME, 30GB ROOT). The system was running fine, before I started using some "CFD" (Graphics Dependent) application. I needed to use "paraview" a graphics software, to design some engineering stuff. Following the installation problems, i installed something called "messa" on my system. The software works but, now my system is "dead-slow". Even with the computer at an idle state, the laptop, is pretty slow, and with huge annoying fan noise. I was tried running some similar applications with windows, and it turns out that its not a hardware, but has to do with the GPU drivers. Following some forums, I installed the "nvidia-current" and now everything is the same. I know, there are many solutions on this forum for nvidia-driver updates, but as you see, nothings working my way. Please someone, tell me what is that I am doing wrong :( This is the output from my terminal for the command lspci | grep 'intel' 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) 00:01.0 PCI bridge: Intel Corporation Xeon E3-1200/2nd Generation Core Processor Family PCI Express Root Port (rev 09) 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 00:16.0 Communication controller: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 (rev 04) 00:1a.0 USB Controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #2 (rev 05) 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05) 00:1c.0 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 1 (rev b5) 00:1c.1 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 2 (rev b5) 00:1c.3 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 4 (rev b5) 00:1c.4 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 5 (rev b5) 00:1c.5 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 6 (rev b5) 00:1d.0 USB Controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 (rev 05) 00:1f.0 ISA bridge: Intel Corporation HM67 Express Chipset Family LPC Controller (rev 05) 00:1f.2 SATA controller: Intel Corporation 6 Series/C200 Series Chipset Family 6 port SATA AHCI Controller (rev 05) 00:1f.3 SMBus: Intel Corporation 6 Series/C200 Series Chipset Family SMBus Controller (rev 05) 03:00.0 Network controller: Intel Corporation Centrino Wireless-N 1030 (rev 34)

• Reporting on common code smells : A POC

  - by Dave Ballantyne

  Over the past few blog entries, I’ve been looking at parsing TSQL scripts in a variety of ways for a variety of tasks.  In my last entry ‘How to prevent ‘Select *’ : The elegant way’, I looked at parsing SQL to report upon uses of SELECT *.  The obvious question leading on from this is, “Great, what about other code smells ?”  Well, using the language service parser to do that was turning out to be a bit of a hard job,  sure I was getting tokens but no real context.  I wasn't even being told when an end of statement had been reached. One of the other parsing options available from Microsoft is exposed in the assembly ‘Microsoft.SqlServer.TransactSql.ScriptDom’,  this is ,I believe, installed with the client development tools with SQLServer.  It is much more feature rich than the original parser I had used and breaks a TSQL script into intuitive classes for analysis. So, what sort of smells can I now find using it ?  Well, for an opening gambit quite a nice little list. Use of NOLOCK Set of READ UNCOMMITTED Use of SELECT * Insert without column references Explicit datatype conversion on Sargs Cross server selects Non use of two-part naming convention Table and Query hint usage Changes in set options Use of single line comments Use of ordinal column positions in ORDER BY clause Now, lets not argue the point that “It depends” as smells on some of these, but as an academic exercise it is quite interesting.  The code is available from this link :https://www.dropbox.com/s/rfk32sou4fzl2cw/TSQLDomTest.zip  All the usual disclaimers apply to this code, I cannot be held responsible for anything ranging from mild annoyance through to universe destruction due to the use of this code or examples. The zip file contains a powershell script and my test cases.  The assembly used requires .Net 4 to run, which means that you will need powershell 3 ( though im running through PowerGUI and all works ok ) .  The code searches for all .sql files in the folder hierarchy for the workingpath,  you can override this if you want by simply changing the $Folder variable, and processes each in turn for the smells.  Feedback is not great at the moment, all it does is output to an xml file (Smells.xml) the offset position and a description of the smell found. Right now, I am interested in your feedback.  What do you think ?  Is this (or should it be) more than an academic exercise ?  Can tooling such as this be used as some form of code quality measure ?  Does it Work ? Do you have a case listed above which is not being reported ? Do you have a case that you would love to be reported ? Let me know , please mailto: [email protected]. Thanks

• Software monetization that is not evil

  - by t0x1n

  I have a free open-source project with around 800K downloads to date. I've been contacted by some monetization companies from time to time and turned them down, since I didn't want toolbar malware associated with my software. I was wondering however, is there a non-evil way to monetize software ? Here are the options as I know them: Add a donation button. I don't feel comfortable with that as I really don't need "donations" - I'm paid quite well. Donating users may feel entitled to support etc. (see the second to last bullet) Add ads inside your application. In the web that may be acceptable, but in a desktop program it looks incredibly lame. Charge a small amount for each download. This model works well in the mobile world, but I suspect no one will go for it on the desktop. It doesn't mix well with open source, though I suppose I could charge only for the binaries (most users won't go to the hassle of compiling the sources). People may expect support etc. after having explicitly paid (see next bullet). Make money off a service / community / support associated with the program. This is one route I definitely don't want to take, I don't want any sort of hassle beyond coding. I assure you, the program is top notch (albeit simple) and I'm not aware of any bugs as of yet (there are support forums and blog comments where users may report them). It is also very simple, documented, and discoverable so I do think I have a case for supplying it "as is". Add affiliate suggestions to your installer. If you use a monetization company, you lose control over what they propose. Unless you can establish some sort of strong trust with the company to supply quality suggestions (I sincerely doubt it), I can't have that. Choosing your own affiliate (e.g. directly suggesting Google Toolbar) is possibly the only viable solution to my mind. Problem is, where do I find a solid affiliate that could actually give value to the user rather than infect his computer with crapware? I thought maybe Babylon (not the toolbar of course, I hate toolbars)?

• Throwing exception from a property when my object state is invalid

  - by Rumi P.

  Microsoft guidelines say: "Avoid throwing exceptions from property getters", and I normally follow that. But my application uses Linq2SQL, and there is the case where my object can be in invalid state because somebody or something wrote nonsense into the database. Consider this toy example: [Table(Name="Rectangle")] public class Rectangle { [Column(Name="ID", IsPrimaryKey = true, IsDbGenerated = true)] public int ID {get; set;} [Column(Name="firstSide")] public double firstSide {get; set;} [Column(Name="secondSide")] public double secondSide {get; set;} public double sideRatio { get { return firstSide/secondSide; } } } Here, I could write code which ensures that my application never writes a Rectangle with a zero-length side into the database. But no matter how bulletproof I make my own code, somebody could open the database with a different application and create an invalid Rectangle, especially one with a 0 for secondSide. (For this example, please forget that it is possible to design the database in a way such that writing a side length of zero into the rectangle table is impossible; my domain model is very complex and there are constraints on model state which cannot be expressed in a relational database). So, the solution I am gravitating to is to change the getter to: get { if(firstSide > 0 && secondSide > 0) return firstSide/secondSide; else throw new System.InvalidOperationException("All rectangle sides should have a positive length"); } The reasoning behind not throwing exceptions from properties is that programmers should be able to use them without having to make precautions about catching and handling them them. But in this case, I think that it is OK to continue to use this property without such precautions: if the exception is thrown because my application wrote a non-zero rectangle side into the database, then this is a serious bug. It cannot and shouldn't be handled in the application, but there should be code which prevents it. It is good that the exception is visibly thrown, because that way the bug is caught. if the exception is thrown because a different application changed the data in the database, then handling it is outside of the scope of my application. So I can't do anything about it if I catch it. Is this a good enough reasoning to get over the "avoid" part of the guideline and throw the exception? Or should I turn it into a method after all? Note that in the real code, the properties which can have an invalid state feel less like the result of a calculation, so they are "natural" properties, not methods.

• Should Exterrnal USB hard drive auto mount Ubuntu 12.04.01 LTS

  - by Chris Good

  I want to have external USB hard drives automatically mounted when plugged in. I have 2 drives exactly the same except for volume label. They both have the same UUID. I want to be easily able to swap them as I'm using them for backups and want to keep 1 at home for off site backup. I've set up the /etc/fstab so they should mount at different places based on their volume label: /etc/fstab : LABEL=Passport1 /media/Passport1 ntfs defaults,windows_names,locale=en_US.utf8 0 0 LABEL=Passport2 /media/Passport2 ntfs defaults,windows_names,locale=en_US.utf8 0 0 blkid shows : ... /dev/sdc1: LABEL="Passport2" UUID="4E1AEA7B1AEA6007" TYPE="ntfs" /dev/sdd1: LABEL="Passport1" UUID="4E1AEA7B1AEA6007" TYPE="ntfs" They both mount automatically during reboot but do not mount when just plugged in to a running system. I've read lots of stuff about this, much of it is old so I'm not sure if it applies. I've read some stuff that says the mounts should happen automatically when plugged in, and lots of other stuff that says you have to install other software to make this happen, although much of it just seems to set up the fstab. What's the real story? Here is /var/log/syslog when drive is plugged in: Dec 14 11:22:58 ausyvutims1 kernel: [66221.300196] usb 1-1: new high-speed USB device number 6 using ehci_hcd Dec 14 11:22:58 ausyvutims1 mtp-probe: checking bus 1, device 6: "/sys/devices/pci0000:00/0000:00:11.0/0000:02:03.0/usb1/1-1" Dec 14 11:22:58 ausyvutims1 mtp-probe: bus: 1, device: 6 was not an MTP device Dec 14 11:22:58 ausyvutims1 kernel: [66221.656020] scsi7 : usb-storage 1-1:1.0 Dec 14 11:22:59 ausyvutims1 kernel: [66222.661534] scsi 7:0:0:0: Direct-Access WD My Passport 0748 1016 PQ: 0 ANSI: 6 Dec 14 11:22:59 ausyvutims1 kernel: [66222.666466] scsi 7:0:0:1: Enclosure WD SES Device 1016 PQ: 0 ANSI: 6 Dec 14 11:22:59 ausyvutims1 kernel: [66222.667739] sd 7:0:0:0: Attached scsi generic sg3 type 0 Dec 14 11:22:59 ausyvutims1 kernel: [66222.667913] ses 7:0:0:1: Attached Enclosure device Dec 14 11:22:59 ausyvutims1 kernel: [66222.668047] ses 7:0:0:1: Attached scsi generic sg4 type 13 Dec 14 11:22:59 ausyvutims1 kernel: [66222.678473] sd 7:0:0:0: [sdc] 1953458176 512-byte logical blocks: (1.00 TB/931 GiB) Dec 14 11:22:59 ausyvutims1 kernel: [66222.687700] sd 7:0:0:0: [sdc] Write Protect is off Dec 14 11:22:59 ausyvutims1 kernel: [66222.687705] sd 7:0:0:0: [sdc] Mode Sense: 47 00 10 08 Dec 14 11:22:59 ausyvutims1 kernel: [66222.701076] sd 7:0:0:0: [sdc] No Caching mode page present Dec 14 11:22:59 ausyvutims1 kernel: [66222.701081] sd 7:0:0:0: [sdc] Assuming drive cache: write through Dec 14 11:22:59 ausyvutims1 kernel: [66222.738062] sd 7:0:0:0: [sdc] No Caching mode page present Dec 14 11:22:59 ausyvutims1 kernel: [66222.738068] sd 7:0:0:0: [sdc] Assuming drive cache: write through Dec 14 11:22:59 ausyvutims1 kernel: [66222.754558] sdc: sdc1 Dec 14 11:22:59 ausyvutims1 kernel: [66222.792006] sd 7:0:0:0: [sdc] No Caching mode page present Dec 14 11:22:59 ausyvutims1 kernel: [66222.792012] sd 7:0:0:0: [sdc] Assuming drive cache: write through Dec 14 11:22:59 ausyvutims1 kernel: [66222.792016] sd 7:0:0:0: [sdc] Attached SCSI disk Dec 14 11:22:59 ausyvutims1 ata_id[16971]: HDIO_GET_IDENTITY failed for '/dev/sdc': Invalid argument Thanks for any help offered

• Questions about identifying the components in MVC

  - by luiscubal

  I'm currently developing an client-server application in node.js, Express, mustache and MySQL. However, I believe this question should be mostly language and framework agnostic. This is the first time I'm doing a real MVC application and I'm having trouble deciding exactly what means each component. (I've done web applications that could perhaps be called MVC before, but I wouldn't confidently refer to them as such) I have a server.js that ties the whole application together. It does initialization of all other components (including the database connection, and what I think are the "models" and the "views"), receiving HTTP requests and deciding which "views" to use. Does this mean that my server.js file is the controller? Or am I mixing code that doesn't belong there? What components should I break the server.js file into? Some examples of code that's in the server.js file: var connection = mysql.createConnection({ host : 'localhost', user : 'root', password : 'sqlrevenge', database : 'blog' }); //... app.get("/login", function (req, res) { //Function handles a GET request for login forms if (process.env.NODE_ENV == 'DEVELOPMENT') { mu.clearCache(); } session.session_from_request(connection, req, function (err, session) { if (err) { console.log('index.js session error', err); session = null; } login_view.html(res, user_model, post_model, session, mu); //I named my view functions "html" for the case I might want to add other output types (such as a JSON API), or should I opt for completely separate views then? }); }); I have another file that belongs named session.js. It receives a cookies object, reads the stored data to decide if it's a valid user session or not. It also includes a function named login that does change the value of cookies. First, I thought it would be part of the controller, since it kind of dealt with user input and supplied data to the models. Then, I thought that maybe it was a model since it dealt with the application data/database and the data it supplies is used by views. Now, I'm even wondering if it could be considered a View, since it outputs data (cookies are part of HTTP headers, which are output)

• Deferred Shading - Toolkit

  - by AliveDevil

  I recently managed to get some lights rendered in a scene by using a buffer and a for-loop. The problem with this method is the performance drop if more lights are used. I tried to convert Deferred Rendering in XNA4.0 | ROY-T.NL but it is not working, because I am not using any models. I know I have to render color, normals and lights seperate but I don't know how I could get it working. For understanding my structure better I'm using a world-class which holds some chunks. These chunks are loading all vertices from their items. These items have a property which returns the vertices. The item is returning VertexPositionNormalTexture[]. The chunk loads these Vertices and combines them to one large array of VertexPositionNormalTexture via someList.AsParallel().SelectMany(m => m).ToArray()). m is a VertexPositionNormalTexture. someList is List<VertexPositionNormalTexture>. I got my own shader to draw these vertices how I want them to be drawn. The first thing I would try is setting up two RenderTarget2D for rendering the color and normal part. With two different shaders. Than I would have to render the lights and there's the problem: I don't know how. I set up a structure to simplify working with lights but it didn't really help. public struct Light { public Vector3 Position; public Color4 Color; public float Range; public float Intensity; public Light( Vector3 position, Color color, float range, float intensity ) : this() { this.Position = position; this.Color = color; this.Range = range; this.Intensity = intensity; } public float[] Definition { get { return new[] { Position.X, Position.Y, Position.Z, Color.Red, Color.Green, Color.Blue, Intensity, Range }; } } } The next part is equally different because I don't know how to combine the colorMap, normalMap and textureMap to one finalMap. Some information to the system: I'm using SharpDX (Nightly from some months ago) and the SharpDX.Toolkit (I don't want to mess up with Direct3DDevice and similar things). Can someone help me with this problem? If things are missing or I provided insufficient information tell me, I need to get deferred shading working. Things I'm not able to do: create a rendertarget which holds all lights, merge colorMap, normalMap and lightMap to one finalMap and presenting this to the user.

• Started wrong with a project. Should I start over?

  - by solidsnake

  I'm a beginner web developer (one year of experience). A couple of weeks after graduating, I got offered a job to build a web application for a company whose owner is not much of a tech guy. He recruited me to avoid theft of his idea, the high cost of development charged by a service company, and to have someone young he can trust onboard to maintain the project for the long run (I came to these conclusions by myself long after being hired). Cocky as I was back then, with a diploma in computer science, I accepted the offer thinking I can build anything. I was calling the shots. After some research I settled on PHP, and started with plain PHP, no objects, just ugly procedural code. Two months later, everything was getting messy, and it was hard to make any progress. The web application is huge. So I decided to check out an MVC framework that would make my life easier. That's where I stumbled upon the cool kid in the PHP community: Laravel. I loved it, it was easy to learn, and I started coding right away. My code looked cleaner, more organized. It looked very good. But again the web application was huge. The company was pressuring me to deliver the first version, which they wanted to deploy, obviously, and start seeking customers. Because Laravel was fun to work with, it made me remember why I chose this industry in the first place - something I forgot while stuck in the shitty education system. So I started working on small projects at night, reading about methodologies and best practice. I revisited OOP, moved on to object-oriented design and analysis, and read Uncle Bob's book Clean Code. This helped me realize that I really knew nothing. I did not know how to build software THE RIGHT WAY. But at this point it was too late, and now I'm almost done. My code is not clean at all, just spaghetti code, a real pain to fix a bug, all the logic is in the controllers, and there is little object oriented design. I'm having this persistent thought that I have to rewrite the whole project. However, I can't do it... They keep asking when is it going to be all done. I can not imagine this code deployed on a server. Plus I still know nothing about code efficiency and the web application's performance. On one hand, the company is waiting for the product and can not wait anymore. On the other hand I can't see myself going any further with the actual code. I could finish up, wrap it up and deploy, but god only knows what might happen when people start using it. What do you think I should do?

• Code Coverage for Maven Integrated in NetBeans IDE 7.2

  - by Geertjan

  In NetBeans IDE 7.2, JaCoCo is supported natively, i.e., out of the box, as a code coverage engine for Maven projects, since Cobertura does not work with JDK 7 language constructs. (Although, note that Cobertura is supported as well in NetBeans IDE 7.2.) It isn't part of NetBeans IDE 7.2 Beta, so don't even try there; you need some development build from after that. I downloaded the latest development build today. To enable JaCoCo features in NetBeans IDE, you need do no different to what you'd do when enabling JaCoCo in Maven itself, which is rather wonderful. In both cases, all you need to do is add this to the "plugins" section of your POM: <plugin> <groupId>org.jacoco</groupId> <artifactId>jacoco-maven-plugin</artifactId> <version>0.5.7.201204190339</version> <executions> <execution> <goals> <goal>prepare-agent</goal> </goals> </execution> <execution> <id>report</id> <phase>prepare-package</phase> <goals> <goal>report</goal> </goals> </execution> </executions> </plugin> Now you're done and ready to examine the code coverage of your tests, whether they are JUnit or TestNG. At this point, i.e., for no other reason than that you added the above snippet into your POM, you will have a new Code Coverage menu when you right-click on the project node: If you click Show Report above, the Code Coverage Report window opens. Here, once you've run your tests, you can actually see how many classes have been covered by your tests, which is pretty useful since 100% tests passing doesn't mean much when you've only tested one class, as you can see very graphically below: Then, when you click the bars in the Code Coverage Report window, the class under test is shown, with the methods for which tests exist highlighted in green and those that haven't been covered in red: (Note: Of course, striving for 100% code coverage is a bit nonsensical. For example, writing tests for your getters and setters may not be the most useful way to spend one's time. But being able to measure, and visualize, code coverage is certainly useful regardless of the percentage you're striving to achieve.) Best of all about all this is that everything you see above is available out of the box in NetBeans IDE 7.2. Take a look at what else NetBeans IDE 7.2 brings for the first time to the world of Maven: http://wiki.netbeans.org/NewAndNoteworthyNB72#Maven

• Do I need to create my own or use a commercial server for the features and matchmaking options I want my game to support?

  - by baptzmoffire

  So I'm developing an indie turn-based game for iOS and, in coding up a Game Center matchmaking class, I'm starting to question whether Game Center is even the best choice for what I want this game to do. I need to figure out whether I need to create my own server, invest in a preexisting client or server service, or if I even need to use a server at all. If I do need to use a ready-made service other than Game Center, which server would accomodate my game's needs best? I have limited resources and funds. Here is the list of features I want my game to support, ideally: Turn-based gameplay (a la "with Friends" and "with Buddies" games) Smart matchmaking (matching users up with other players of comparable skill/achievements) Random matchmaking Facebook matchmaking Specific username matchmaking Contact list matchmaking A way to select what "type" of match you want to challenge an opponent to. (In random, smart, and Facebook matchmaking, there will be different "wagers" the player can make. [e.g. "I wanna play a random opponent for 1000 points. Now, I wanna play my Facebook buddy for 1,000,000 points."] There will be a predetermined range of amounts you can play for. It won't be customizable.) Buddies list capability (Game-buddies, as opposed to contacts and Facebook) A higher concurrent game cap than Game Center offers (which I still can't really find a straight answer on) Scalability (it should support 2 or 20,000,000 players) Objective-C compatibility Flexibility (for all the stuff I haven't thought of yet) Am I dreaming, here? Is there even a service that can handle all of these features? Do I need to invest months in learning a networking language to build my own? If so, how much would I need to spend on hardware? I've been looking around all morning and, so far, the only seemingly viable option is SmartFox. Under "Everything and the kitchen sink" section here, it says they support "virtual world with Zones, Rooms and RoomGroups, create complex game challenges, send invitations, manage buddy lists, create custom permission profiles, oversee the security aspects and tons more." http://www.smartfoxserver.com/overview/platform Is there an option that Im just overlooking? Thanks for any help anyone can provide. Sorry for the long poast. One last question: Does anyone know which server Dice with Buddies uses? I was experimenting with how many concurrent games I could get going and my ADHD kicked in at about 80 games. 80 concurrent games would be great for my game, but again, I need the other features I mentioned too. Thanks again.

• F# Objects &ndash; Integrating with the other .Net Languages &ndash; Part 1

  - by MarkPearl

  In the next few blog posts I am going to explore objects in F#. Up to now, my dabbling in F# has really been a few liners and while I haven’t reached the point where F# is my language of preference – I am already seeing the benefits of the language when solving certain types of programming problems. For me I believe that the F# language will be used in a silo like architecture and that the real benefit of having F# under your belt is so that you can solve problems that F# lends itself towards and then interact with other .Net languages in doing the rest. When I was still very new to the F# language I did the following post covering how to get F# & C# to talk to each other. Today I am going to use a similar approach to demonstrate the structure of F# objects when inter-operating with other languages. Lets start with an empty F# class … type Person() = class end   Very simple, and all we really have done is declared an object that has nothing in it. We could if we wanted to make an object that takes a constructor with parameters… the code for this would look something like this… type Person =     {         Firstname : string         Lastname : string     }   What’s interesting about this syntax is when you try and interop with this object from another .Net language like C# - you would see the following…   Not only has a constructor been created that accepts two parameters, but Firstname and Lastname are also exposed on the object. Now it’s important to keep in mind that value holders in F# are immutable by default, so you would not be able to change the value of Firstname after the construction of the object – in C# terms it has been set to readonly. One could however explicitly state that the value holders were mutable, which would then allow you to change the values after the actual creation of the object. type Person = { mutable Firstname : string mutable Lastname : string }   Something that bugged me for a while was what if I wanted to have an F# object that requires values in its constructor, but does not expose them as part of the object. After bashing my head for a few moments I came up with the following syntax – which achieves this result. type Person(Firstname : string, Lastname : string) = member v.Fullname = Firstname + " " + Lastname What I haven’t figured out yet is what is the difference between the () & {} brackets when declaring an object.

• Web Development Goes Pre-Visual InterDev

  - by Ken Cox [MVP]

  As a longtime and hardcore ASP.NET webforms developer, I’m finding the new client-side development world a bit of a grind.  I love learning new technologies, but I can’t help feeling we’ve regressed and lost our old RAD advantage as we move heavy lifting to the client. For my latest project, I’m using Telerik’s KendoUI in Visual Studio 2012. To say I feel clumsy writing this much JavaScript is an understatement. It seems like the only safe way to ‘write’ this code is by copying a working snippet from someone else and pasting it into my HTML page.  For me, JavaScript has largely been for small UI tasks like client-side validation and a bit of AJAX – and often emitted by a server-side control. I find myself today lost in nests of curly braces that Ctrl+K, Ctrl+D doesn’t seem to understand that well either. IntelliSense, my old syntax saviour, doesn’t seem to have kept up with this cobweb of code either. Code completion? Not seeing it. As I fumbled about this evening, I thought about how web development rocketed forward when Microsoft introduced Visual InterDev. Its Design-Time Controls (DTCs) changed the way we created sites. All the iterations of Visual Studio have enhanced that server-side experience where you let a tool write the bulk of the code and manually finesse it from there. What happened? Why am I typing  properties and values (especially default values!) into VS 2012 to get a client-side grid on a page? Where are the drag and drop objects that traditionally provided 70 percent of the mark-up and configuration?  Did we forget how to write Property Pages where you enter a value and the correct syntax appears magically in the source code? To me, the tooling was looking the other way as the scene shifted from server-side code to nimble client-side script. It’ll have to catch up. Although JavaScript is the lingua franca of web browsers, the language is unwieldy, tough to maintain, and messy to debug. If a .NET JIT compiler can turn our VB, F#, and C# source code into an Intermediate Language that executes on a computer, I don’t see why there can’t be a client-side compiler that turns a .NET language into JavaScript that browsers can consume.

• Asynchronously returning a hierarchal data using .NET TPL... what should my return object "look" like?

  - by makerofthings7

  I want to use the .NET TPL to asynchronously do a DIR /S and search each subdirectory on a hard drive, and want to search for a word in each file... what should my API look like? In this scenario I know that each sub directory will have 0..10000 files or 0...10000 directories. I know the tree is unbalanced and want to return data (in relation to its position in the hierarchy) as soon as it's available. I am interested in getting data as quickly as possible, but also want to update that result if "better" data is found (better means closer to the root of c:) I may also be interested in finding all matches in relation to its position in the hierarchy. (akin to a report) Question: How should I return data to my caller? My first guess is that I think I need a shared object that will maintain the current "status" of the traversal (started | notstarted | complete ) , and might base it on the System.Collections.Concurrent. Another idea that I'm considering is the consumer/producer pattern (which ConcurrentCollections can handle) however I'm not sure what the objects "look" like. Optional Logical Constraint: The API doesn't have to address this, but in my "real world" design, if a directory has files, then only one file will ever contain the word I'm looking for.  If someone were to literally do a DIR /S as described above then they would need to account for more than one matching file per subdirectory. More information : I'm using Azure Tables to store a hierarchy of data using these TPL extension methods. A "node" is a table. Not only does each node in the hierarchy have a relation to any number of nodes, but it's possible for each node to have a reciprocal link back to any other node. This may have issues with recursion but I'm addressing that with a shared object in my recursion loop. Note that each "node" also has the ability to store local data unique to that node. It is this information that I'm searching for. In other words, I'm searching for a specific fixed RowKey in a hierarchy of nodes. When I search for the fixed RowKey in the hierarchy I'm interested in getting the results FAST (first node found) but prefer data that is "closer" to the starting point of the hierarchy. Since many nodes may have the particular RowKey I'm interested in, sometimes I may want to get a report of ALL the nodes that contain this RowKey.

• What is the use of Association, Aggregation and Composition (Encapsulation) in Classes

  - by SahilMahajanMj

  I have gone through lots of theories about what is encapsulation and the three techniques of implementing it, which are Association, Aggregation and Composition. What i found is, Encapsulation Encapsulation is the technique of making the fields in a class private and providing access to the fields via public methods. If a field is declared private, it cannot be accessed by anyone outside the class, thereby hiding the fields within the class. For this reason, encapsulation is also referred to as data hiding. Encapsulation can be described as a protective barrier that prevents the code and data being randomly accessed by other code defined outside the class. Access to the data and code is tightly controlled by an interface. The main benefit of encapsulation is the ability to modify our implemented code without breaking the code of others who use our code. With this feature Encapsulation gives maintainability, flexibility and extensibility to our code. Association Association is a relationship where all object have their own lifecycle and there is no owner. Let’s take an example of Teacher and Student. Multiple students can associate with single teacher and single student can associate with multiple teachers but there is no ownership between the objects and both have their own lifecycle. Both can create and delete independently. Aggregation Aggregation is a specialize form of Association where all object have their own lifecycle but there is ownership and child object can not belongs to another parent object. Let’s take an example of Department and teacher. A single teacher can not belongs to multiple departments, but if we delete the department teacher object will not destroy. We can think about “has-a” relationship. Composition Composition is again specialize form of Aggregation and we can call this as a “death” relationship. It is a strong type of Aggregation. Child object dose not have their lifecycle and if parent object deletes all child object will also be deleted. Let’s take again an example of relationship between House and rooms. House can contain multiple rooms there is no independent life of room and any room can not belongs to two different house if we delete the house room will automatically delete. The question is: Now these all are real world examples. I am looking for some description about how to use these techniques in actual class code. I mean what is the point for using three different techniques for encapsulation, How these techniques could be implemented and How to choose which technique is applicable at time.

• What does the Spring framework do? Should I use it? Why or why not?

  - by sangfroid

  So, I'm starting a brand-new project in Java, and am considering using Spring. Why am I considering Spring? Because lots of people tell me I should use Spring! Seriously, any time I've tried to get people to explain what exactly Spring is or what it does, they can never give me a straight answer. I've checked the intros on the SpringSource site, and they're either really complicated or really tutorial-focused, and none of them give me a good idea of why I should be using it, or how it will make my life easier. Sometimes people throw around the term "dependency injection", which just confuses me even more, because I think I have a different understanding of what that term means. Anyway, here's a little about my background and my app : Been developing in Java for a while, doing back-end web development. Yes, I do a ton of unit testing. To facilitate this, I typically make (at least) two versions of a method : one that uses instance variables, and one that only uses variables that are passed in to the method. The one that uses instance variables calls the other one, supplying the instance variables. When it comes time to unit test, I use Mockito to mock up the objects and then make calls to the method that doesn't use instance variables. This is what I've always understood "dependency injection" to be. My app is pretty simple, from a CS perspective. Small project, 1-2 developers to start with. Mostly CRUD-type operations with a a bunch of search thrown in. Basically a bunch of RESTful web services, plus a web front-end and then eventually some mobile clients. I'm thinking of doing the front-end in straight HTML/CSS/JS/JQuery, so no real plans to use JSP. Using Hibernate as an ORM, and Jersey to implement the webservices. I've already started coding, and am really eager to get a demo out there that I can shop around and see if anyone wants to invest. So obviously time is of the essence. I understand Spring has quite the learning curve, plus it looks like it necessitates a whole bunch of XML configuration, which I typically try to avoid like the plague. But if it can make my life easier and (especially) if make it can make development and testing faster, I'm willing to bite the bullet and learn Spring. So please. Educate me. Should I use Spring? Why or why not?

• A "First" at Oracle OpenWorld

  - by Kathryn Perry

  A guest post by Adam May, Director, Fusion CRM, Oracle Applications Development There are always firsts at OpenWorld. These firsts keep the conference fresh and are the reason people come back year after year. An important first this year is our Fusion CRM customers who are using the product and deriving real benefit from Fusion CRM. Everyone can learn from and interact with them -- including us!  We love talking to customers, especially those who are using our solutions in unexpected ways because they challenge us! At previous OpenWorlds, we presented our overall Fusion vision and our plans for Fusion CRM. Those presentations helped customers plan their strategies and map out their new release uptakes. Fast forward to March of this year when the first Fusion CRM customer went live. Since then we've watched the pace of go-lives accelerate every single month. Now we're at the threshold of another OpenWorld -- with over 45,000 attendees, 2,500 sessions and LOTS of other activities. To avoid having our customers curl into a ball with sensory overload, we designed a Focus On Document to outline the most important Fusion CRM activities. Here are some of the highlights: Anthony Lye's "Oracle Fusion Customer Relationship Management: Overview/Strategy/Customer Experiences/Roadmap" on Monday at 3:15 p.m. The CRM Pavilion, open in Moscone West from Monday through Wednesday; features our strategic Fusion CRM partners and provides live demonstrations of their capabilities General Session: "Oracle Fusion CRM--Improving Sales Effectiveness, Efficiency, and Ease of Use" on Tuesday at 11:45 a.m.; features Anthony Lye and Deloitte "Meet the Fusion CRM Experts" on Tuesday at 5:00 p.m.; this session gives customers the opportunity to interact one-on-one with Fusion experts divided into eight categories of expertise CRM Social Reception on Tuesday from 6-8 p.m.; there's no better way to spend the early evening than discussing Fusion CRM with Oracle experts and strategic partners over appetizers and drinks Wednesday night is Oracle's Customer Appreciation event; enjoy Pearl Jam, Kings of Leon, etc. beginning at 7:30 p.m. at Treasure Island Be sure to drink plenty of water before sleeping Wednesday night and don't stay out too late because we have lots of great content on Thursday; at the top of the list is "Oracle Fusion Social CRM Strategy and Roadmap: Future of Collaboration and Social Engagement" at 11:15 a.m. We hope you have a fantastic experience at OpenWorld 2012! And here's a little video treat to whet your appetite: http://www.youtube.com/user/FusionAppsAtOracle
