• Ubuntu Froze Keyboard and mouse (laptop)

  - by fernando

  something similar to what happened to me was this post Updates kill Keyboard and mouse. unfortunately I'm stuck there. I also read on a couple other threads that I should go and use recovery mode, but when i select the option from GRUB it stops at a certain point, the screen that will allow me to fix packages won't appear. i decided to diagnose the computer, and test the RAM; so far everything seems to be going well. but this whole thing happened when I was doing an update around 230mb's... i still havent found a solution to the frozen Keyboard and mouse (trackpad). but if all else fails can i just reinstall Ubuntu? would that fix the issue? what else can I try? btw, I'm not not great with coding, so if there is anything that I need to type and put correct syntax or anything please guide me through it. I've had Ubuntu literally for 1 day, and this happens. any suggestions would be appreciated.

• A Simple Solution For NetBeans RCP Apps That Need A Groovy Editor

  - by Geertjan

  Take a look at Nils Hoffmann's metabolomic analyzer, especially at the Groovy editor contained within it: Obviously, it would be cool if the Groovy editor in the app above were to have syntax coloring and other editor features helpful in coding Groovy. However, as I showed in If You Include the Groovy Editor, there are multiple dependencies that the NetBeans Groovy support has on other modules that would be completely superfluous in the above application, while they'd make the app much heavier than it is, simply because of all the Groovy dependencies. But today I thought of a simple solution. Why not take the Groovy.g file (i.e., the ANTLR definition), such as this one [though that's probably not the most up to date one, wondering how to find the most up to date one] and then apply the content of this screencast (made by me) to the Groovy.g file: Within a few minutes, you should end up with Groovy syntax coloring. OK, so that's not a full blown Groovy editor, but syntax coloring is surely a cool thing to have in the app with which this blog entry started? Sure, this means creating a new Groovy editor from scratch. But the point is that doing so can be very simple, i.e., the syntax coloring can simply be generated via the simple instructions above. I'm going to try it myself in the next few days, but would be cool if others out there would try this too!

• Is my JS/Jquery methodology good?

  - by absentx

  I always struggle with which of the stack sites is best to post "questions of theory" like this, but I think programmers is the best, if not, as usual a mod will move it etc... I am seeking critique on what has become my normal methodology of writing javascript. I have become heavily reliant on the Jquery library, but I think this has helped me learn the native language better also. Anyways, please critique the following style of JS coding...buried are a lot of questions of scope, if you could point out the strengths and weaknesses of this style I would appreciate it. var critique ={ start: function(){ globalness = 'GLOBAL-GLOBAL'; //available to all critique's methods var notglobalness = 'LOCAL-LOCAL';// only available to critiques start method //am I using the "method" teminology properly here?? $('#stuff').on('click','a.closer-target',function(){ $target = $(this); if($target.hasClass('active')){ $target.removeClass('active'); } else{ $target.addClass('active'); critique.madness($target); } }) console.log(notglobalness+': at least I am useful at home'); console.log('note here that: '+notglobalness+' is no longer available after this point, lets continue on:'); critique.madness(notglobalness); }, madness: function($e){ // do a bunch of awesomeness with $e //but continue to keep it seperate because you think its best to keep things isolated. //send to the next function when complete here console.log('here is globalness, which is still available from the start method of critique!! ' + globalness); console.log('lets see if the globalness carries on to a new var object!!'); console.log('the locally isolated variable of NOTGLOBALNESS is available here because it was passed to this method, lets show it:'+$e); carryOn.start(); } } //end critique var carryOn={ start: function(){ console.log('any chance critique.globalness will work here??? lets see: ' +globalness); console.log('it absolutely does'); } } $(document).ready(critique.start);

• 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

• Why is NDA so hard to understand?

  - by Dave Campbell

  Maybe this concept is simpler for me because of all the jobs I've been on over the years requiring security clearances. I've signed quite a few NDA forms. Some for big companies, some for small, but the meaning of "NDA" remains constant: Non-Disclosure Agreement. To me, that takes no further explanation, but apparently it's confusing to some people, and I don't understand how you can be confused. The papers I signed with the U.S. Army in 1970 read "10 years and $10,000" for a violation... can't imagine what it's up to now, but THAT is a strict NDA :) So those things I've been told, I cannot talk about, period. Even if the entire world knows about them, I cannot speak about them until the information goes off NDA. An example was a Silverlight release a while back. It might have been Silverlight 3, I don't remember. Everyone was anxiously awaiting the release so they could post their material. Of course the entire world knew it was coming out and imminently so. Some enterprising folks had even found the bits on a server before the official announcement. So then the situation became: everyone knew about it, some were even coding with it and blogging about it and yet we couldn't talk about it. Scott Guthrie's posting about it opened the flood gates and then it went off NDA, but up until that moment, we were locked. Sitting out on the edge you're uninstalling and re-installing all the time and you get frustrated when things that used to work don't, but hey... those bits were still warm when you got 'em, and that's the fun. But that fun comes at a price, and the price is the NDA. Awkward yes, confusing no... See you at MIX10, and Stay in the 'Light! MIX10

• how to choose a web framework and javascript library?

  - by Trylks

  I've been procrastinating learning some framework for web apps w/ some library for AJAX, something like django with prototype, or turbogears with mootools, or zeta components with dojo, grok, jquery, symfony... The point is to spend some of my spare time, have "fun" and create cool stuff that hopefully is some useful. I think maybe I wouldn't like something like GWT or pyjamas because I wouldn't like to "get married" with some technology, I want to keep my freedom to add another javascript library, and so on. I didn't decide even the language yet, but I think I'd prefer python. PHP could be fine if there is some framework that is nice enough. Besides that, I don't even know where to start. I don't feel like learning a framework to then realize there is something that I cannot comfortably do, switch to another framework then find that a third framework has something really cool, etc. And the same goes for javascript libraries. So, some guidance would be really appreciated. I don't really know why are so many options available and what do they aim for, I guess some of them focus on some aspects and some on others, but I just want to make cool and nice apps that I can easily maintain, without spending too much time on coding or learning and avoiding the "trapped in the framework" feeling, when doing something is awfully complicated (or even impossible) with compared with the rest of things or doing that same thing on a different framework. I guess in the end I'll go for django and jquery since they are the most widely used options, afaik, but if I was going for the most widely used options I guess I should choose Java or PHP (I don't really like Java for my spare time, but php is not so bad), so I preferred to ask first. I think the question has to consider both, framework and library, since sometimes they are coupled. I think this is the place to ask this kind of things, sorry if not, and thank you.

• Restful WebAPI VS Regular Controllers

  - by Rohan Büchner

  I'm doing some R&D on what seems like a very confusing topic, I've also read quite a few of the other SO questions, but I feel my question might be unique enough to warrant me asking. We've never developed an app using pure WebAPI. We're trying to write a SPA style app, where the back end is fully decoupled from the front end code Assuming our service does not know anything about who is accessing/consuming it: WebAPI seems like the logical route to serve data, as opposed to using the standard MVC controllers, and serving our data via an action result and converting it to JSON. This to me at least seems like an MC design... which seems odd, and not what MVC was meant for. (look mom... no view) What would be considered normal convention in terms of performing action(y) calls? My sense is that my understanding of WebAPI is incorrect. The way I perceive WebAPI, is that its meant to be used in a CRUD sense, but what if I want to do something like: "InitialiseMonthEndPayment".... Would I need to create a WebAPI controller, called InitialiseMonthEndPaymentController, and then perform a POST... Seems a bit weird, as opposed to a MVC controller where i can just add a new action on the MonthEnd controller called InitialisePayment. Or does this require a mindset shift in terms of design? Any further links on this topic will be really useful, as my fear is we implement something that might be weird an could turn into a coding/maintenance concern later on?

• What's so bad about pointers in C++?

  - by Martin Beckett

  To continue the discussion in Why are pointers not recommended when coding with C++ Suppose you have a class that encapsulates objects which need some initialisation to be valid - like a network socket. // Blah manages some data and transmits it over a socket class socket; // forward declaration, so nice weak linkage. class blah { ... stuff TcpSocket *socket; } ~blah { // TcpSocket dtor handles disconnect delete socket; // or better, wrap it in a smart pointer } The ctor ensures that socket is marked NULL, then later in the code when I have the information to initialise the object. // initialising blah if ( !socket ) { // I know socket hasn't been created/connected // create it in a known initialised state and handle any errors // RAII is a good thing ! socket = new TcpSocket(ip,port); } // and when i actually need to use it if (socket) { // if socket exists then it must be connected and valid } This seems better than having the socket on the stack, having it created in some 'pending' state at program start and then having to continually check some isOK() or isConnected() function before every use. Additionally if TcpSocket ctor throws an exception it's a lot easier to handle at the point a Tcp connection is made rather than at program start. Obviously the socket is just an example, but I'm having a hard time thinking of when an encapsulated object with any sort of internal state shouldn't be created and initialised with new.

• How to solve my big communication issue and take care in future

  - by Rahul Mehta

  My company had a POC which was done by me,my senior ,my boss and our channel partner team 4 people and our company team done most of coding and first installation of the softwares of the POC was done by channel partner team, and documented the same thing, i had installed on our server, Our comapny team worked very hard. Now we are about to start second stage of POC. But today my boss told me that my senior and channel partner team have issue with me ,regarding my communication. So before considering me on this project they want to resolve this issue or not considered me . I agree i have less communications skills. and I don't ask any question till i need to any one , i prefer to ask on stackoverflow. But i don't know, how this issue is being arise ,i had done all the things they asked , replied to all email and talk on phone. I always obeyed them. I always told them what they asked. what should i do that these type of issue doesn't arrive in future. And now boss told me to prepare a script to talk with my senior to resolve the issue. what should i talk to my senior?

• Finally! Entity Framework working in fully disconnected N-tier web app

  - by oazabir

  Entity Framework was supposed to solve the problem of Linq to SQL, which requires endless hacks to make it work in n-tier world. Not only did Entity Framework solve none of the L2S problems, but also it made it even more difficult to use and hack it for n-tier scenarios. It’s somehow half way between a fully disconnected ORM and a fully connected ORM like Linq to SQL. Some useful features of Linq to SQL are gone – like automatic deferred loading. If you try to do simple select with join, insert, update, delete in a disconnected architecture, you will realize not only you need to make fundamental changes from the top layer to the very bottom layer, but also endless hacks in basic CRUD operations. I will show you in this article how I have  added custom CRUD functions on top of EF’s ObjectContext to make it finally work well in a fully disconnected N-tier web application (my open source Web 2.0 AJAX portal – Dropthings) and how I have produced a 100% unit testable fully n-tier compliant data access layerfollowing the repository pattern. http://www.codeproject.com/KB/linq/ef.aspx In .NET 4.0, most of the problems are solved, but not all. So, you should read this article even if you are coding in .NET 4.0. Moreover, there’s enough insight here to help you troubleshoot EF related problems. You might think “Why bother using EF when Linq to SQL is doing good enough for me.” Linq to SQL is not going to get any innovation from Microsoft anymore. Entity Framework is the future of persistence layer in .NET framework. All the innovations are happening in EF world only, which is frustrating. There’s a big jump on EF 4.0. So, you should plan to migrate your L2S projects to EF soon.

• Where do I start in regards to making a Gnome/Unity Form Application

  - by JMK

  Ok so I am familiar with developing Form and Console applications on Windows using Visual Studio .Net with C#, but where do I start when it comes to Linux distro's like Ubuntu, is there an equivalent? How would one go about matching what they can do in a Windows environment with .Net and C# in a Linux environment without .Net coding in something like Java or C/C++? I am aware of Eclipse, does eclipse have a form designer or do you have to code the design of any Gnome/Unity forms manually? Can I use eclipse to write the Linux equivalent of a console application, that you just double click on to run? I also know about Mono, but the idea is that I want to learn how to develop software without using anything in the Microsoft stack and am not sure where to start. What is the standard language/framework used to develop these types of applications on Linux? As I become more proficient with Visual Studio, C# and .Net, it has struck me that without these Microsoft tools, I am nothing. I am only capable of developing for the Microsoft OS and this scares me. This isn't some anti Microsoft thing, Microsoft makes some incredible Software/Hardware/Operating Systems/IDE's, but it is generally a bad idea to put all of your eggs in one basket so if I want to learn how to develop Terminal and Gnome/Unity form applications where in the world do I start? I have used Linux on and off for years, but Windows has been my primary OS. However I have watched Linux get better and better and as much as I love Windows 7, I am dubious about Windows 8 (I for one will sorely miss my start menu)! Obviously MS aren't going anywhere anytime soon and I could spend the the next couple of decades developing for .Net without any issues but just because you can get away with something doesn't always mean it's a good idea. Thanks

• Biggest mistake you've ever made

  - by Rogue Coder

  Similar to the question I read on Server Fault, what is the biggest mistake you've ever made in an IT related position. Some examples from friends: I needed to do some work on a production site so I decided to copy over the live database to the beta site. Pretty standard, but when I went to the beta site it was still pulling out-of-date info. OOPS! I had copied the beta database over to the live site! Thank god for backups. And for me, I created a form for an event that was to be held during a specific time range. Participants would fill out the form for a chance to win, and we would send the event organizers a CSV from the database. I went into the database, and found ONLY 1 ENTRY, MINE. Upon investigating, it appears as though I forgot an auto increment key, and because of the server setup there was no way to recover the lost data. I am aware this question is similar to ones on Stack Overflow but the ones I found seemed to receive generic answers instead of actual stories :) What is the biggest coding error/mistake ever…

• Preventing possible burnout in a junior dev, or perhaps I'm not doing enough?

  - by m.edmondson

  I'm a software developer with 5 years experience over 3 companies. Within the last year a junior (brand new to the industry) has started at my current employer. I believe he is an excellent developer, who always delivers and is skilled as solving complex problems. However I'm slightly concerned that he is possibly applying himself too much for the following reasons: He begins work approximately 2 hours before most (and is expected) In his free time he has developed an application that was clearly months worth of work that is specific to our employer I and the team are completely greatful for all he is doing, and is clearly an asset to our team. However I'm worried that this is not sustainable. I can almost see that he has the same enthusiasm that I had when I began coding for work, however over the years I've realised that extra curricular work not only doesn't progress your career, but eats into your all important free time. The question I'm asking is: Should I advise him to take things a bit more slowly? Or perhaps I need to learn from him and do more for my employer out of hours?

• Invalid Html Response and JS Errors when you open your Application in Visual Studio 2013

  - by imran_ku07

   I was working on an application which uses Telerik controls. The application was working fine for a while. Suddenly, the application stopped working. I mean lot of my application pages becoming very very ugly. I found JavaScript errors on every Browser's console. When I check the page view-source, the generated HTML was messy and invalid. This was only happening with my local machine. If someone else on my network accesses my application pages, he will get the correct HTML and no JavaScript errors. My mind was blowing because the same page was generating invalid HTML(and JavaScript errors) when I access the page using a local browser but generate correct HTML(and no JavaScript errors) when someone else access my application page remotely. Then I realized that I the only change I made last was opening my application in Visual Studio 2013 RTM which I installed few days ago. I closed the Visual Studio 2013, everything work like a charm. Then I became100% sure that this is only happening due to new Visual Studio 2013 feature called Browser Link. I just open the application again and add this in web.config. Everything become fine Happy coding :)   <add key="vs:EnableBrowserLink" value="false" />

• Cloud Computing - just get started already!

  - by BuckWoody

  OK - you've been hearing about "cloud" (I really dislike that term, but whatever) for over two years. You've equated it with just throwing some VM's in some vendor's datacenter - which is certainly part of it, but not the whole story. There's a whole world of - wait for it - *coding* out there that you should be working on. If you're a developer, this is just a set of servers with operating systems and the runtime layer (like.NET, Java, PHP, etc.) that you can deploy code to and have it run. It can expand in a horizontal way, allowing massive - and I really, honestly mean massive, not just marketing talk kind of scale. We see this every day. If you're not a developer, well, now's the time to learn. Explore a little. Try it. We'll help you. There's a free conference you can attend in November, and you can sign up for it now. It's all on-line, and the tools you need to code are free. Put down Facebook and Twitter for a minute - go sign up. Learn. Do. :) See you there. http://www.windowsazureconf.net/

• Documenting your database with Visual Studio 2012 SSDT tools

  - by krislankford

  The title of this post is interesting and something I am wishing you and your colleagues had a better way to do. I understand as I am asked this question frequently. I couple of weeks ago I was asked the same question by a customer who documents their database using the ApexSQL Doc tools which uses the extended properties on objects to create automated documentation. I thought that was super interesting and went down the path to see how we could could support the creation of this documentation while leveraging the Visual Studio 2012 SSDT Tools. What I found is was rather intriguing. There is a property called “Description” on all objects in the SSDT tools. This property is rather subtle and I am betting overlooked. To be honest, this property has probably been there for a while and I just never discovered it. Adding text to this '”Description” property it allows Visual Studio to create the commands for the extended properties directly to your schema which should be version controlled. As I did more digging there seemed to be extended properties at every level in the SQL database objects. This fills some rather challenging gaps and allows organizations to manage SQL Schema using the Visual Studio SQL database tools while allowing a way to automatically document the database. This will also work in the automation of the creation and alter scripts that can be generated as part f an automated build system. Now we essentially get a way to store, build and document the database in a nice little ALM package. Happy Coding!

• How to get that first development job

  - by cju

  I have been in QA for 10 years, trying to get into developement for about 5 of them. I have taken classes in C++, Java and C#. I was able to write some tools and unit tests in C# at my current job and (by all accounts) did a good job of it. However, 8 months ago, my employer tasked me with the responsibility of establishing the new QA group. Now, I'm doing manual testing and deployment with no promise of returning to development. I have looked at the job boards and there are a lot of jobs for Web developers and wondered how I could break into that. I've picked up some books on Ruby on Rails that I plan to work through on the Mac at home, but I'm not sure employers would be interested in anything but commercial web development. Do you have any suggestions on how I can use my experience to get a job as a junior developer? And I mean one that entailes programming...the postings I've seen for junior developer amount to doing all the grunt work besides coding. They should just call them "Technical Secretaries".

• How best to keep bumbling, non-technical managers at bay and still deliver good work?

  - by Curious

  This question may be considered subjective (I got a warning) and be closed, but I will risk it, as I need some good advice/experience on this. I read the following at the 'About' page of Fog Creek Software, the company that Joel Spolsky founded and is CEO of: Back in the year 2000, the founders of Fog Creek, Joel Spolsky and Michael Pryor, were having trouble finding a place to work where programmers had decent working conditions and got an opportunity to do great work, without bumbling, non-technical managers getting in the way. Every high tech company claimed they wanted great programmers, but they wouldn’t put their money where their mouth was. It started with the physical environment (with dozens of cubicles jammed into a noisy, dark room, where the salespeople shouting on the phone make it impossible for developers to concentrate). But it went much deeper than that. Managers, terrified of change, treated any new idea as a bizarre virus to be quarantined. Napoleon-complex junior managers insisted that things be done exactly their way or you’re fired. Corporate Furniture Police writhed in agony when anyone taped up a movie poster in their cubicle. Disorganization was so rampant that even if the ideas were good, it would have been impossible to make a product out of them. Inexperienced managers practiced hit-and-run management, issuing stern orders on exactly how to do things without sticking around to see the farcical results of their fiats. And worst of all, the MBA-types in charge thought that coding was a support function, basically a fancy form of typing. A blunt truth about most of today's big software companies! Unfortunately not every developer is as gutsy (or lucky, may I say?) as Joel Spolsky! So my question is: How best to work with such managers, keep them at bay and still deliver great work?

• Extending AutoVue Through the API

  - by GrahamOracle

  The AutoVue API (previously called the “VueBean” API) is a great way to extend AutoVue Client/Server Deployment – specifically the client component – beyond the out-of-the-box capabilities and into new use-cases. In addition to having a solid grasp of J2SE programming, make sure to leverage the following resources if you’re developing or interested in developing customizations/extensions to AutoVue Client/Server Deployment: Programmer’s Guide: Before all else, read through the AutoVue API Programmer’s Guide to get an understanding of the architecture of the API. The Programmer’s Guide is included with the installation of AutoVue, and is posted on the Oracle Technology Network (OTN) website for the recent versions of AutoVue: http://www.oracle.com/technetwork/documentation/autovue-091442.html Javadocs: The AutoVue API Javadocs document the many packages, classes, and methods available to you. The Javadocs are included in the product installation under the \docs\JavaDocs\VueBean folder (easiest starting point is through the file index.html). Integrations Forum: If you have development questions that aren’t answered through the documentation, feel free to register and post in the public AutoVue Integrations Forum. For more information refer to the following blog post from October 2010: https://blogs.oracle.com/enterprisevisualization/entry/exciting_news_autovue_integrat Code Samples: Although the Oracle Support team’s scope of Support for API/customization topics is to answer questions regarding information already provided in the documentation (i.e. not to design or develop custom solutions), there are cases where Support comes across interesting samples or code snippets that may benefit various customers. In those cases, our Support team posts the samples into the Oracle knowledge base, and tracks them through a single reference note.

• How to provide value?

  - by Francisco Garcia

  Before I became a consultant all I cared about was becoming a highly skilled programmer. Now I believe that what my clients need is not a great hacker, coder, architect... or whatever. I am more and more convinced every day that there is something of greater value. Everywhere I go I discover practices where I used to roll my eyes in despair. I saw the software industry with pink glasses and laughed or cried at them depending on my mood. I was so convinced everything could be done better. Now I believe that what my clients desperately need is finding a balance between good engineering practices and desperate project execution. Although a great design can make a project cheap to maintain thought many years, usually it is more important to produce quick fast and cheap, just to see if the project can succeed. Before that, it does not really matters that much if the design is cheap to maintain, after that, it might be too late to improve things. They need people who get involved, who do some clandestine improvements into the project without their manager approval/consent/knowledge... because they are never given time for some tasks we all know are important. Not all good things can be done, some of them must come out of freewill, and some of them must be discussed in order to educate colleagues, managers, clients and ourselves. Now my big question is. What exactly are the skills and practices aside from great coding that can provide real value to the economical success of software projects? (and not the software architecture alone)

• Server outputs the sourcecode of PHP page

  - by Akhilesh B Chandran

  I have a Shared Hosting package with HostGator. In it, I'm hosting around 4 websites. They are just some simple sites that doesn't likely to attract more visitors. But a few days ago, when I accessed one of my sites(via a browser), it outputted the PHP code of index.php, instead of outputting it as HTML. I think, at that time, the server was a bit busy or something. I heard that, Facebook also have got a similar condition where the home page's code was made available. So, how do I take preventive measures for this ? I always use phpBB forum's style of coding. That is, each sub pages, common functions, etc. are separated into subfolders. And in PHP, I would just include_once() or require_once() it. Also, these subfolders have a .htaccess file in which I have set the deny permission to the files inside it from outside. Also, in the main page(index), I would define a constant. And the first line of the subpages(which is situated in separate folders) is to check whether this constant is set. If not, calls die(). I am looking forward for solutions to this problem of outputting raw code when the page is accessed. Thanks in advance :)

• Documenting mathematical logic in code

  - by Kiril Raychev

  Sometimes, although not often, I have to include math logic in my code. The concepts used are mostly very simple, but the resulting code is not - a lot of variables with unclear purpose, and some operations with not so obvious intent. I don't mean that the code is unreadable or unmaintainable, just that it's waaaay harder to understand than the actual math problem. I try to comment the parts which are hardest to understand, but there is the same problem as in just coding them - text does not have the expressive power of math. I am looking for a more efficient and easy to understand way of explaining the logic behind some of the complex code, preferably in the code itself. I have considered TeX - writing the documentation and generating it separately from the code. But then I'd have to learn TeX, and the documentation will not be in the code itself. Another thing I thought of is taking a picture of the mathematical notations, equations and diagrams written on paper/whiteboard, and including it in javadoc. Is there a simpler and clearer way? P.S. Giving descriptive names(timeOfFirstEvent instead of t1) to the variables actually makes the code more verbose and even harder too read.

• Best practices for App Idea ownership and shares

  - by JOG

  I am developing apps on my sparetime. I am the sole developer, and two non-programmer friends of mine provide vision, content, algorithms and ideas. We always agree happily on all the features, todos and prioritizations. But naturally, coding it is the biggest part. When selling, we agree on splitting profit equally, that is 33% each. But version 1.0 naturally does not sell much. And I go on to try to make the app more viral. This includes tons of stuff where the others are of little help. Examples: Adding support for sharing, facebook connect, gameifying, letting users add content, home page, support, maintenance, server services to make it easier for to update content. The list is long. Suddenly I will be doing 100% of a lot of work but only "own" a third of the income. My friends may either "fade out" of the project after 1.0, or they continue to contribute, but with less value and I would rather exchange them for more programmers or graphic designers. The effort they made to version 1.0 is worth a lot to the app and I realize I would have never done it without them. But I am doing all the work in the end. It is hard to negotiate about splitting 90, 5, 5 instead of 33% each, because the idea is still theirs. How to solve this? What are the best practices to regard the ownership of the app? What kind of agreements could I make that make it beneficial and motivational for me to continue developing the app?

• AJAX driven "page complete" function? Am I doing it right?

  - by Julian H. Lam

  This one might get me slaughtered, since I'm pretty sure it's bad coding practice, so here goes: I have an AJAX driven site which loads both content and javascript in one go using Mootools' Request.HTML. Since I have initialization scripts that need to be run to finish "setting up" the template, I include those in a function called pageComplete(), on every page Visiting one page to another causes the previous pageComplete() function to no longer apply, since a new one is defined. The javascript function that loads pages dynamically calls pageComplete() blindly when the AJAX call is completed and is loaded onto the page: function loadPage(page, params) { // page is a string, params is a javascript object if (pageRequest && pageRequest.isRunning) pageRequest.cancel(); pageRequest = new Request.HTML({ url: '<?=APPLICATION_LINK?>' + page, evalScripts: true, onSuccess: function(tree, elements, html) { // Empty previous content and insert new content $('content').empty(); $('content').innerHTML = html; pageComplete(); pageRequest = null; } }).send('params='+JSON.encode(params)); } So yes, if pageComplete() is not defined in one the pages, the old pageComplete() is called, which could potentially be disastrous, but as of now, every single page has pageComplete() defined, even if it is empty. Good idea, bad idea?
