• When and why you should use void (instead of i.e. bool/int)

  - by Jonas

  I occasionally run into methods where a developer chose to return something which isn't critical to the function. I mean, when looking at the code, it apparently works just as nice as a void and after a moment of thought, I ask "Why?" Does this sound familiar? Sometimes I would agree that most often it is better to return something like a bool or int, rather then just do a void. I'm not sure though, in the big picture, about the pros and cons. Depending on situation, returning an int can make the caller aware of the amount of rows or objects affected by the method (e.g., 5 records saved to MSSQL). If a method like "InsertSomething" returns a boolean, I can have the method designed to return true if success, else false. The caller can choose to act or not on that information. On the other hand, May it lead to a less clear purpose of a method call? Bad coding often forces me to double-check the method content. If it returns something, it tells you that the method is of a type you have to do something with the returned result. Another issue would be, if the method implementation is unknown to you, what did the developer decide to return that isn't function critical? Of course you can comment it. The return value has to be processed, when the processing could be ended at the closing bracket of method. What happens under the hood? Did the called method get false because of a thrown error? Or did it return false due to the evaluated result? What are your experiences with this? How would you act on this?

• Beyond S&OP: Integrated Business Planning

  - by Paul Homchick

  In most corporations, planning is done at the department level — leaving disconnects and gaps across different departments. Finance sets revenue and profit goals with minimum validation from Manufacturing that the company has the resources, material, capacity, or demand to reach these goals. On the operations side, Manufacturing is developing plans to balance demand and supply but seldom knows if the resulting "plan" will meet the budgets on which the company's revenue and profit goals are based. The Sales department agrees to quotas that meet Finance's revenue goals without a complete understanding of what manufacturing can deliver. Integrated Business Planning (IBP) bridges these gaps in corporate planning systems. Integrated Business Planning integrates the financial planning provided by EPM systems with operations planning provided by Sales and Operations Planning solutions. This means that revenue goals and budgets are validated against a bottom-up operating plan, and that the operating plan is reconciled against financial goals. When detailed changes are made to the operations plan, planners can immediately see the big picture impact of the changes. IBP also addresses one the CFO's big concerns—the reliability of the revenue forecast. Operating plans are updated daily or weekly from a precise forecast based on current market conditions. These updated plans are then made available so that financial analysts are working with data that best represents what is going to happen - not what they projected would happen based on last quarter's data. For a discussion in more depth, see my article: Improve Reliability of Financial Forecasts with Integrated Business Planning in Supply & Demand Chain-Executive Magazine.

• Why do some bad websites rank well?

  - by BradB

  Consider the following scenario: you are pitching SEO/Website Optimisation to a prospective client and you explain to them the importance of great copy and content, how acquiring links (ethically) can increase page rank, why the quality of the HTML build matters (H1, H2 tags, w3c validation etc), why keyword research is beneficial, you may drop in a few Google Webmaster Guideline or Matt Cutts references to back up your claims and rubbish the "back hat" approach as being no longer effective for good measure. Your advice is ethical and in the eyes of best practices, spot on. Then, the client points out to you some of their long established competitors on Google and you see these competitor websites ranking in the top spots (1 to 3) for medium to highly competitive search phrases that your client wants to compete for. These websites totally contradict your ethical approach and pretty much violate every best practice previously noted. They even out perform other "white hat" competitors who are in accordance with the above guidelines. I experienced this today. One of these well ranking websites had: About six microsites with more or less the same copy and a slightly varied layout Little or not textual content I would almost say duplicate content across the sites, but there was so little of it it could barely qualify for being duplicate All the content in Flash (with a music track that kicked in on each page load, not so much of an SEO issue - but it helps paint the picture) Keyword stuffing behind the Flash file with a bunch of black text on black background in the style of keyword 1 keyword 2,keyword1,keyword 2,keyword 2 keyword 3 and so on... The exact keyword stuffed combination present on every page of the website A bunch of clearly self made links from poor quality forums and directories with little or no Page Rank Links exchanged across the microsites How do you explain your way out of this when this hard evidence is sat in front of you undermining your great pitch?

• How to Hibernate from .NET Apps and How to enable Hibernate in Windows XP

  The usage of Computer desktop or laptop is increased all around the world phenomenally. This link gives you the picture on how power consumption is for various devices we use daily. to reduce the power consumption Hibernate is one of the best way provided by default in Windows Vista or Windows 7. Hibernate feature enables you to close the machine without closing your applications, that means the applications will be restored as they were once we restart the machine. Hibernate feature is not enabled in Windows XP by default. I’ve seen many people that they run (do not switch off) the machines months and months as they do not want to close the windows or applications running in Windows XP. below are the steps to enable Hibernate in Windows XP. Right click on Desktop. Click on properties. Go to screen save tab. Click on power button Select Hibernate tab Check the checkbox “Enabled Hibernate” Apply the settings. Now when you try to shutdown, “Shut down windows” dialog shows “Hibernate” options. Now you can safely close the machine without closing your applications or windows as they will be restored once you on the machine. </SPAN? Some time you might want to provide this future programmatically for the applications you develop for windows. Generally you might want to provide this option in windows applications where process needs huge time. Download managers are the one of the best example. below is the code to do a Hibernate from the .NET code. using System.Windows.Forms;namespace CodeKicks.WinApp.Machine{ public static class MyMachineHelper { public static void DoHibernate() { //Application.SetSuspendState(PowerState.Suspend, true, false); Application.SetSuspendState(PowerState.Hibernate, true, false); } }} span.fullpost {display:none;}

• OT: Fixing choppy video playback on OS X

  - by terrencebarr

  This is a bit off-topic but I wanted to share because it seems a lot of people are running into issues with choppy video playback and stutter on Mac OS X. I am using a Mac Mini with Snow Leopard (10.6.8) as a home media center and it has worked great in the past, playing back music and videos from multiple sources (web, quicktime, VLC, EyeTV). A few weeks ago the video playback from all my sources started to become choppy, to stutter, and often the picture would hang for seconds at a time. Totally unusable. Drove me nuts for two weeks. After much research and trial-and-error it turns out the problem was an outdated Flash Player which seems to have messed up the video pipeline for the entire system. The short is, I updated the Flash Player to version 11 directly from the Adobe web site, rebooted the Mac Mini, and all is well again! Judging from the various posts across the web, video playback appears to be a fairly widespread problem for Mac users and I hope this helps some of you out there! And I can’t wait to get rid of Flash altogether – I can’t remember the times it has crashed my browser, hung my system, and screwed up things. Thanks Adobe ;-( Cheers, – Terrence Filed under: Uncategorized Tagged: Adobe Flash, Mac OS X

• Highlighting rows and columns in an HTML table using JQuery

  - by nikolaosk

  A friend of mine was seeking some help regarding HTML tables and JQuery. I have decided to write a few posts demonstrating the various techniques I used with JQuery to achieve the desired functionality. ?here are other posts in my blog regarding JQuery.You can find them all here.I have received some comments from visitors of this blog that are "complaining" about the length of the blog posts. I will not write lengthy posts anymore...I mean I will try not to do so..We will demonstrate this with a step by step example. I will use Visual Studio 2012 Ultimate. You can also use Visual Studio 2012 Express Edition. You can also use VS 2010 editions. 1) Launch Visual Studio. Create an ASP.Net Empty Web application. Choose an appropriate name for your application.2) Add a web form, default.aspx page to the application.3) Add a table from the HTML controls tab control (from the Toolbox) on the default.aspx page4) Now we need to download the JQuery library. Please visit the http://jquery.com/ and download the minified version.5) We will add a stylesheet to the application (Style.css)5) Obviously at some point we need to reference the JQuery library and the external stylesheet. In the head section ? add the following lines.   <link href="Style.css" rel="stylesheet" type="text/css" />       <script src="jquery-1_8_2_min.js" type="text/javascript"></script> 6) Now we need to highlight the rows when the user hovers over them.7) First we need to type the HTML markup<body>    <form id="form1" runat="server">    <div>        <h1>Liverpool Legends</h1>        <table style="width: 50%;" border="1" cellpadding="10" cellspacing ="10">            <thead>                <tr><th>Defenders</th><th>MidFielders</th><th>Strikers</th></tr>            </thead>            <tbody>            <tr>                <td>Alan Hansen</td>                <td>Graeme Souness</td>                <td>Ian Rush</td>            </tr>            <tr>                <td>Alan Kennedy</td>                <td>Steven Gerrard</td>                <td>Michael Owen</td>            </tr>            <tr>                <td>Jamie Garragher</td>                <td>Kenny Dalglish</td>                <td>Robbie Fowler</td>            </tr>            <tr>                <td>Rob Jones</td>                <td>Xabi Alonso</td>                <td>Dirk Kuyt</td>            </tr>                </tbody>        </table>            </div>    </form></body>8) Now we need to write the simple rules in the style.css file.body{background-color:#eaeaea;}.hover { background-color:#42709b; color:#ff6a00;} 8) Inside the head section we also write the simple JQuery code.  <script type="text/javascript"> $(document).ready(function() { $('tr').hover( function() { $(this).find('td').addClass('hover'); }, function() { $(this).find('td').removeClass('hover'); } ); }); </script>9) Run your application and see the row changing background color and text color every time the user hovers over it. Let me explain how this functionality is achieved.We have the .hover style rule in the style.css file that contains some properties that define the background color value and the color value when the mouse will be hovered on the row.In the JQuery code we do attach the hover() event to the tr elements.The function that is called when the hovering takes place, we search for the td element and through the addClass function we apply the styles defined in the .hover class rule in the style.css file.I remove the .hover rule styles with the removeClass function. Now let's say that we want to highlight only alternate rows of the table.We need to add another rule in the style.css.alternate { background-color:#42709b; color:#ff6a00;} The JQuery code (comment out the previous JQuery code) follows  <script type="text/javascript">        $(document).ready(function() {                     $('table tr:odd').addClass('alternate');        });    </script>  When I run my application through VS I see the following result You can do that with columns as well. You can highlight alternate columns as well.The JQuery code (comment out the previous JQuery code) follows  <script type="text/javascript">        $(document).ready(function() {                      $('td:nth-child(odd)').addClass('alternate');        });    </script>  In this script I use the nth-child() method in the JQuery code.This method retrieves all the elements that are nth children of their parent.Have a look at the picture below to see the resultsYou can also change color to each individual cell when hovered on.The JQuery code (comment out the previous JQuery code) follows    <script type="text/javascript">        $(document).ready(function() {          $('td').hover(                  function() {                 $(this).addClass('hover');               },                function() {                    $(this).removeClass('hover');                }                );        });    </script> Have a look at the picture below to see the results. Hope it helps!!!

• Greiner-Hormann clipping problem

  - by Belgin

  I have a set of planar polygons in 3D space defined by their vertices in counterclockwise order. Let's define the 'positive face' as being the face of the 3D polygon such as when observed, the vertices appear in counterclockwise order, and the 'negative face', the face which when observed, the vertices appear in clockwise order. I'm doing perspective projection of the set of polygons onto a projection polygon defined by the points in this order: (0, h, 0), (0, 0, 0), (w, 0, 0), and (w, h, 0), where w and h are strictly positive integers. The positive face of this projection polygon is oriented towards positive Z, and the camera point is somewhere at (0, 0, d), where d is a strictly negative number. In order to 'clip' the projected polygons into the projection polygon, I'm applying the Greiner-Hormann (PDF) clipping algorithm, which requires that the clipper and the to-be-clipped polygons be in the same order (i.e. clockwise or counterclockwise). My question is the following: How can I determine whether the projected face of the 3D polygon is the negative or the positive one? Meaning, how do I find out if I have to work with the vertices in normal or inverted order for the algorithm to work? I noticed that only if the 3D polygon is facing the projection polygon with its negative face, both of them are in the same order (counterclockwise), otherwise, a modification needs to be done. Here is a picture (PNG) that illustrates this. Note that the planes described by the polygon from the set and the projection polygon may not always be parallel.

• How to distribute python GTK applications?

  - by Nik

  This is in correlation with the previous question I asked here. My aim is to create and package an application for easy installation in Ubuntu and other debian distributions. I understand that the best way to do this is by creating .deb file with which users can easily install my application on their system. However, I would also like to make sure my application is available in multiple languages. This is why I raised the question before which you can read here. In the answers that were provided, I was asked to use disutils for my packaging. I am however missing the bigger picture here. Why is there a need to include a setup.py file when I distribute my application in .deb format? My purpose is to ensure that users do not need to perform python setup.py to install my application but rather just click on the .deb file. I already know how to create a deb file from the excellent tutorial available here. It clearly shows how to edit rules, changelog and everything required to create a clean deb file. You can look at my application source code and folder structure at Github if it helps you better understand my situation. Please note I have glanced through the official python documentation found here. But I am hoping that I would get an answer which would help even a lame man understand since my knowledge is pretty poor in this regard.

• Distinction between API and frontend-backend

  - by Jason

  I'm trying to write a "standard" business web site. By "standard", I mean this site runs the usual HTML5, CSS and Javascript for the front-end, a back-end (to process stuff), and runs MySQL for the database. It's a basic CRUD site: the front-end just makes pretty whatever the database has in store; the backend writes to the database whatever the user enters and does some processing. Just like most sites out there. In creating my Github repositories to begin coding, I've realized I don't understand the distinction between the front-end back-end, and the API. Another way of phrasing my question is: where does the API come into this picture? I'm going to list some more details and then questions I have - hopefully this gives you guys a better idea of what my actual question is, because I'm so confused that I don't know the specific question to ask. Some more details: I'd like to try the Model-View-Controller pattern. I don't know if this changes the question/answer. The API will be RESTful I'd like my back-end to use my own API instead of allowing the back-end to cheat and call special queries. I think this style is more consistent. My questions: Does the front-end call the back-end which calls the API? Or does the front-end just call the API instead of calling the back-end? Does the back-end just execute an API and the API returns control to the back-end (where the back-end acts as the ultimate controller, delegating tasks)? Long and detailed answers explaining the role of the API alongside the front-end back-end are encouraged. If the answer depends on the model of programming (models other than the Model-View-Controller pattern), please describe these other ways of thinking of the API. Thanks. I'm very confused.

• Process Centric Banking: Loan Origination Solution

  - by Manish Palaparthy

  There is an old proverb that goes, "The difference between theory and practice is greater in practice than in theory". So, we keep doing numerous "Proof of Concepts" with our own products on various business cases to analyze them deeply, understand and explain to our customers. We then present our learnings as they happened. The awareness of each PoC should help readers increase the trustworthiness of the results coming out of these PoCs. I present one such PoC where we invested a lot of time&effort.  Process Centric Banking : Loan Origination Solution Loan Origination is a process by which a borrower applies for a new loan and the lender processes that application. Loan origination includes the series of steps taken by the bank from the point the customer shows interest in a loan product all the way to disbursal of funds. The Loan Origination process is relevant for many kind of lenders in Financial services: Banks, Credit Unions, NBFCs(Non Banking Financial Companies) and so on. For simplicity sake, I will use "Bank" as the lending institution in the rest of my article.  Loan Origination is one of the core processes for Banks as it is the process by which the it creates assets against which the Institution earns most of its profits from. A well tuned loan origination process can affect the Bank in many positive ways. Banks have always shown great interest in automating the loan origination process for the above reason. However, due the constant changes in customer environment, market dynamics, prevailing economic conditions, cost pressures & regulatory environment they run into lot of challenges. Let me categorize some of these challenges for you Customer Environment Multiple Channels: Customer can use any of the available channels (Internet Banking, Email, Fax, Branch, Phone Banking, ATM, Broker, Mobile, Snail Mail) to perform all or some of the activities related to her Visibility into the origination process: Expect immediate update on the status of loan processing & alert messages Reduced Turn Around Time: Expect loans to be processed with least turn around time Reduced loan processing fees: Partly due to market dynamics the customer expects the loan processing fee to be negligible Market Dynamics Competitive environment:  The competition keeps creating many variants of loan products to attract customers, the bank needs to create similar product variants with better offers to attract customers or keep existing ones Ability to migrate loans from one vendor to another: It has become really easy for retail customers to move from one bank to the other given the low fee of loan processing and highly attractive offers. How does the bank protect it's customer base while actively engaging with potential customers banking with competitor banks Flexibility to react to market developments: Market development greatly influence loan processing, underwriting, asset valuation, risk mitigation rules. Can the bank modify rules and policies, the idea is not just to react to market developments but to pro-actively manage new developments Economic conditions Constant change in various rates and their implications on the rates and rules applied when on-boarding a loan: How quickly can the bank apply changes to rates offered to customers when the central bank changes various rates Requirements of Audit by the central banker: Tough economic conditions have demanded much more stringent audit rules and tests. The banks needs to produce ready reports(historic & operational) for audit compliance Risk Mitigation: While risk mitigation has always been a key concern for the bank, this is the area where the bank's underwriters & risk analysts spend the maximum time when processing a loan application. In order to reduce TAT the bank cannot compromise on its risk mitigation strategies Cost pressures Reduce Cost of processing per application: To deliver a reduced loan processing fee to the customer, the bank needs to keep its cost per processing loan application low. Meet customer TAT expectations while reducing the queues and the systems being used to process the loan application: The loan application could potentially be spending a lot of time waiting in the queue for further processing. Different volumes & patterns of applications demand different queuing algorithms. The bank needs to have real-time visibility into these queues and have the flexibility to change queuing algorithms at runtime  Increase the use of electronic communication and reduce the branch channel usage: Lesser automation leads not only leads to Increased turn around time, it also impacts more costs to reach out to customers The objective of our PoC was to implement a Loan Origination Solution whose ownership lies with the bank and effectively meet the challenges listed above. We built a simple story board for the solution We then went about implementing our storyboard using Oracle BPM Suite, Webcenter Content : Imaging. The web UI has been built on ADF technolgies, while the integration with core-services has been implemented using the underlying SOA infrastructure. The BPM process model is quite exhaustive can meet all the challenges listed above to reasonable degree. A bank intending to implement an end-to-end Loan Origination Solution has multiple options at it's disposal. It can Develop a customer Loan Origination Application from scratch: Gives maximum opportunity to build what you want but inflexible to upgrade and maintain. Higher TCO in long term Buy a Packaged application & customize it: Customizing a generic loan application can be tedious and prove as difficult as above. Build it using many disparate & un-integrated tools: Initially seems easier than developing from scratch. But, without integrated tool sets this is not a viable approach either or A solution based on a Framework: Independent Services and Business Process Modeling provide decoupled architecture that is flexible. We built this framework end-to-end with processes the core process of loan origination & several sub-processes such as Analyse and define customer needs, customer credit verification, identity check processes, legal review process, New customer registration & risk assessment.

• Is HTML5/WebGL performance unreliable on low-end Android tablets and phones?

  - by Boris van Schooten

  I've developed a couple of WebGL games, and am trying them out on Android. I found that they run very slowly on my tablet, however. For example, a game with 10 sprites or so runs as 5fps. I tried Chrome and CocoonJS, but they are comparably slow. I also tried other games, and even games with only 5 or so moving sprites are this slow. This seems inconsistent with reports from others, such as this benchmark. Typically, when people talk about HTML5 game performance, they mention well-known and higher-end phones and tables. While my 7" tablet is cheap (I believe it's a relabeled Allwinner tablet, apparently with the Mali 400 GPU), I found it generally has a good gaming performance. All the games I tried run smoothly. I also developed an OpenGL ES 2 demo with 200 shaded 3D objects, and it ran at 50fps. My suspicion is that many low-end and white-label devices may have unacceptable HTML5/WebGL support, which means there may be a large section of gamers you will not reach when you choose this as your platform. I've heard rumors about inconsistent performance of HTML5 and WebGL on different devices, but no clear picture emerges. I would like to hear if any of you have had similar experiences with HTML5 or WebGL, or whether I can find information about the percentage of devices I can expect to have decent performance.

• Managing flash animations for a game

  - by LoveMeSomeCode

  Ok, I've been writing C# for a while, but I'm new to ActionScript, so this is a question about best practices. We're developing a simple match game, where the user selects tiles and tries to match various numbers - sort of like memory - and when the match is made we want a series of animations to take place, and when they're done, remove the tile and add a new one. So basically it's: User clicks the MC Animation 1 on the MC starts Animation 1 ends Remove the MC from the stage Add a new MC Start the animation on the new MC The problem I run into is that I don't want to make the same timeline motion tween on each and every tile, when the animation is all the same. It's just the picture in the tile that's different. The other method I've come up with is to just apply the tweens in code on the main stage. Then I attach an event handler for MOTION_FINISH, and in that handler I trigger the next animation and listen for that to finish etc. This works too, but not only do I have to do all the tweening in code, I have a seperate event handler for each stage of the animation. So is there a more structured way of chaining these animations together?

• Activist shared printing material gallery

  - by Dave

  What would you say would be the best way to do this: We would like to create a section on our activist community FB page and website in order to share with everyone images and files ready for printing panflets, brochures, t-shirts, stickers, etc. Let's say we have some cool slogans for t-shirts, so we would like to show them on a gallery, and offer for download the original design files needed for a print shop to create the t-shirts. And the same thing for all other kinds of media. We want to enable anyone to be able to just download the files for free, and easily create printed materials with them. But besides offering this hybrid between picture gallery and downloads manager, we would also like to make it very easy for anyone to upload and share their own files with the community, to make it a true collaboration initiative, be it that they get posted automatically, or that we first review and approve all uploads. Cafepress or Spreadshirt let you upload your design and sell your own merchandise. We need something similar, but where people can then download working files for making quality printings and materials. What apps, tools, services or methods are out there with which you think this could be best done?? We have some ideas, but we would like to hear some more!!

• We've Been Busy: World Tour 2010

  - by [email protected]

• Presenting the Cloud in a Different Way

  - by BuckWoody

  I had the honor of presenting the Developers at the Portland PASS chapter, and decided to go a different way than just using PowerPoint Slides…. (click on any picture to enlarge) The point is that when you need to get a point across, it’s OK to change tactics to make sure the information sticks. In this case, I decided to make the audience the PowerPoint. I used a few props to show the various paradigms we use to describe what the industry uses for the word “cloud” First, we talked about Infrastructure as a Service. I picked a gentleman who didn’t quite fit the hard hat and safety vest I picked out for him. Notice our “user” as she accesses our “Server” (complete with tray and glass) which has been virtualized.    Software as a service comes next. In this case, the user and potentially even customers just access software (represented here as a Windows ME box…) remotely – everything is virtualized. Finally, Platform as a Service – Yup, Platform shoes as a necklace, and a tie-dye shirt to represent the 70’s – a decade when mainframes used stateless programming as well. Notice also the components of Windows Azure – Compute (Keyboard) Application Fabric (Toy Bus) and Storage (Bucket).   And at the end of the day, it’s all about serving those customers…

• Visual Studio 2010 Keyboard Shortcut Posters Available

  - by Jim Duffy

  I’m a firm believer in the productivity gains you experience when using keyboard shortcuts in Visual Studio. If you’re not using keyboard shortcuts while coding then your productivity is suffering. Some of my favorites (omitting the obvious ones like F5 to start debugging) as are: Ctrl+K, C – Comment section of code Ctrl+K, U – Uncomment section of code Ctrl+K, D – Format the current document (indentation, etc.) Shift+Alt+C – Add new class to a project Shift+Alt+A – Add existing item to a project Ctrl+Shift+A – Add new item to a project The good news is all of these and a TON of others are all documented in the Visual Studio Keyboard Shortcut Posters (available as PDFs). The only problem is there are so many you need a printer capable of printing on larger paper because while you can read them all on 8 1/2 x 11 paper in landscape mode, for them to be a valuable quick reference on your cubicle wall you’re going to need to print them on large paper. If you don’t have a printer capable of producing large sized printouts head down to Office Depot, Staples, FedEx Office, or your favorite print shop and have them print one for you. Oh and one last thing, I’d really like Microsoft to take those people’s picture off them. Really? Do we need to look at these people when trying to improve our productivity? Have a day. :-|
