• How to search drupal site from the new Unity lense?

  - by Ognjen

  I'm creating a simple Unity lense for my college site which is based on Drupal, but I don't know how to adapt this command for Drupal API. Please help, it's python. We now create our query url, using the Wikipedia opensearch API url = ("%s/w/api.php?action=opensearch&limit=25&format=json&search=%s" % (self.wiki, search)) I'm using template to write lense following Wikipedia example http://developer.ubuntu.com/2012/04/how-to-create-a-wikipedia-unity-lens-for-ubuntu/. I don't know python but Im familiar with C. This Drupal API calling is the only problem I have to successfully develop a lense. Please help!

• Amazon GameCircle Integration

  - by user1095509

  I'm trying to integrate Amazon GameCircle and I have been able to successfully initialize GameCircle in my app, but the problem is when I click on the button that displays achievements, the GameCircle achievement list comes up but it says "You have unlocked 0 of 0 achievements". Same happens with leaderboards i.e there are no leaderboards for this app. I have created a Leaderboard and a few achievements on the online developer portal for Amazon but they don't show for some reason. Can someone help me with this. Any links/resources that help with integrating GameCircle will be appreciated. Thanks.

• How can I compile an IP address to country lookup database to make available for free?

  - by Nick

  How would I go about compiling an accurate database of IP addresses and their related countries to make available as an open source download for any web developer who wants to perform a geographic IP lookup? It seems that a company called MaxMind has a monopoly on geographic IP data, because most online tutorials I've seen for country lookups based on IP addresses start by suggesting a subscription to MaxMind's paid service (or their less accurate free 'Lite' version). I'm not completely averse to paying for their solution or using the free one, but the concept of an accurate open source equivalent that anyone can use without restriction appeals to me, and I think it would be useful for the web development community. How is geographic IP data collected, and how realistic is it to hope to maintain an up-to-date open version?

• Building my first ASP.NET WebForms application problem

  - by user1525474

  Hi I have recently started to learn C#/ASP.NET WebForms and after reading two books I thought I was ready to create my first web application. Problem is I could not have been more wrong. Although I am not quite a beginner as a programmer and have done some programming in Java (a Monopoly game), JavaScript (using jQuery), and PHP (create templates for WordPress), I never really created something that is database driven, and I can't seem to figure where to start. I am very confident in my HTML/CSS/jQuery skills, so that is not the problem. My end goal after becoming comfortable in ASP.NET WebForms is to learn MVC, ADO.NET, and the Entity Framework, and start a career as a .NET developer. I would like if someone could tell me some tutorials that build ASP.NET WebForms applications, such as a blog, so I can see what are the steps in creating an ASP.NET WebForms database driven application. I already have to projects in mind for ASP.NET. One is building a blog and the other building a job board.

• New Office 2010 theme added for creating current UIs

  - by Webgui

  Visual WebGui offers its developers a set of out-of-the-box themes which they can easily apply to their applications. This allows developers to focus on the development and business logic rather than dealing with UI design missions. However, design tools and customization freedom are available for those who need to customize current themes or create their own custom theme. As part of the constant updates and enhancements to Visual WebGui and its developer CompanionKit a new available theme was added last week. The new theme applies the latest Microsoft UI - Office 2010 to Visual WebGui and allows developers and/or end users (of 6.4.0 and above) to switch their Web applications UI to the successful design of Office 2010. After the latest update the new theme is integrated into the Visual WebGui Developers CompanionKit which now matches Visual WebGui 6.4.0 Release version's infrastructure. The update also includes several enhancements to existing controls and features and the addition of some new ones. Go to the CompanionKit

• Why to let / not let developers test their own work

  - by pyvi

  I want to gather some arguments as to why letting a developer testing his/her own work as the last step before the product goes into production is a bad idea, because unfortunately, my place of work sometimes does this (the last time this came up, the argument boiled down to most people being too busy with other things and not having the time to get another person familiar with that part of the program - it's very specialised software). There are test plans in this case (though not always), but I am very much in favor of making a person who didn't make the changes that are tested actually doing the final testing. So I am asking if you could provide me with a good and solid list of arguments I can bring up the next time this is discussed. Or to provide counter-arguments, in case you think this is perfectly fine especially when there are formal test cases to test.

• Welcome to our Friday tips series!

  - by Chris Kawalek

  Today we're starting a brand new blog series. For your Friday afternoon reading, we'll be posting a technical tip or question and answer on a technical topic. We'll start by introducing ideas on our own, but we'd really like it if you were involved and asked us questions via Twitter! Tag your tweet with #AskOracleVirtualization and we'll consider your question for the blog. Today's tip is on Storage and Oracle Virtual Desktop Infrastructure: Question: I run Oracle Virtual Desktop 3.4.1 on Solaris and use a local ZFS storage pool.  How should I configure my ZFS ARC cache?  Answer by John Renko, Consulting Developer, Oracle: Oracle recommends about 5G of ARC cache per template in use to achieve up to a 90% disk read offload. Set your ARC min=max to reserve the maximum amount of your remaining memory for your running VMs. In /etc/system: set zfs:zfs_arc_min = 5368709120 set zfs:zfs_arc_max = 5368709120 The amount you need to reserve will depend on your template but this has proven to be a great start for a typical windows 7 VM running productivity applications.

• Real World ADF - another new ADF book hits the stands

  - by Grant Ronald

  I'm pleased to report that yet another Oracle ADF book hits the bookstores this month.  One of my fellow Product Managers, Jobinesh, has written Oracle ADF Real World Developer's Guide.   I'm currently awaiting a copy for review and can't wait to get into this book.  Jobinesh is an incredibly smart and switched-on technical ADF guru and I'm convinced I'm going to learn a whole lot of tips and techniques from this book. Once I get my hands on a copy I'll be writing up a full review. As someone who has written an Oracle ADF book already, I know the effort that goes into something like that, so well done Jobinesh.

• Managing multiple people working on a project with GIT

  - by badZoke

  I'm very new to GIT/GitHub (as new as starting yesterday). I would like to know what is the best way to manage multiple people working on the same project with Github. Currently I'm managing one project with four developers. How do I go about the workflow and making sure everything is in sync? (Note: All developers will have one universal account.) Does each developer need to be on a different branch? Will I be able to handle 2 people working on the same file? Please post a detailed answer, I'm not a shy reader. I need to understand this well.

• Are IE9 really good ?

  - by anirudha

  IE9 started a campaign for kill IE6 from the core because they know that IE6 is a big trouble or  problem for them for promote 9 version of IE. so they started a campaign for killing IE6. next time they kill IE 7 , 8,9 whenever they found this old version have a big problem for them to promote next version of IE.   Why they not make a update system who automatically update the browser and tell user to restart and update goes installed in the user system. well IE9 should learn from all other that they have very well design auto-update system who never give user in trouble that your browser goes old. Chrome and Firefox both update themselves and say user restart to enjoy another good version. in IE6 a big problem is that updates. no one sure that they installed new version of IE6 without any hassles and update goes install without any problem because they really know or care about “you need this to install this and this for this” so they thing “why I update IE whenever I am unsure that my browser goes update and I have no problem again” so they do nothing because their work done with no problem because common person used high profile application who work even in IE6. so they do nothing.    IE6 countdown website have designed a banner for warn or force user to upgrade to next version of IE. well there is no good reason for put the banner on website some of reason are:-   Windows 7 comes with pre-installed IE8 and Vista comes with upgrade version them IE6 so that is sure that you force a user who have Windows XP [luna] and if they want to upgrade IE then they can get IE8 not version 9 because IE9 is design for Windows 7 or Vista Service pack 2. so What is the use of update when user still have a outdate version too because IE8 is old version and not have any capability of HTML5 so forcing user by using the banner have no sense. I am not know why they all listed on website put the banner on their own website. it’s good that you offer user what they want instead of giving them a outdate version of IE again. My means to give a user list of browser they can try to enhance their browser experience instead of only IE.   IE9 build upon WPF and they spent more time on using WPF in IE instead of making user experience browser.  many thing is designed wrongly in IE first thing is tabs. the tabs in chrome are bigger and easily to move and same in Firefox even not have smooth tabbing. IE have same tabbing as chrome have but leak a point that it’s too small. if you really  want to move then sometime they create a problem that they going elsewhere from the current instance of IE.   Chrome have a big buttons, tabs and menu to enhance browser experience and Firefox have a good feature that you can make them bigger or small. you can put the icon for add-ons on the toolbar for easily use but IE have no relation with customization so we never can thinking about that.   When chrome provide lot’s of extensions and a  webstore for browser application and same feature in Firefox can be seen then there is no plugin in IE. really you can see their IE addons Website where no plugin listed for web development. even in the category or tag. as a response from many blog there is new for developer that new version of IE9 developer tool. well IE9 have three new tabs a blogger tell on their blog. when I trying them I found many thing but I still unable to edit the Css from the HTML tab and no plugin I found I can get to enhance IE9 web development. something more other provide never IE9 give me like personas , customization , browser extension or any other they used to tell a small thing customization  .   IE9 still have some problem with JavaScript that when I use Firefox and chrome and logout in both then my cookie is deleted but in IE it’s not done. it’s show me that IE9 still have different from other not for good thing even some bad thing too. When I trying to read a article that is written in Hindi using Unicode font I found that they show many thing misspelled. there is three Sha in Hindi but they all goes wrong in IE. the misprint thing is not that the writing  for the articles goes wrong. it’s problem or browser to rendering a font. the Firefox and chrome not give me this problem even opera render the font in italic style by decrease the font-size but all those work perfect.   in Pwn2Own the apple’s safari  and IE9 both are hacked. this is a awesome news for whose who thing that  open-source is lose in  Security and close-source is highly-secured software. well this is not a good parameter for talking about software. it’s should depend how much application tested and used. because more testing and more use of application make them better.   I  appreciate IE to making their new version 9 and good luck for them. there is a another matter that I personally found nothing on them.

• What's typical in terms of royalties? [closed]

  - by Matt Phillips

  I'm a developer negotiating compensation for a commercialized version of some data analysis software I wrote (see my profile if you like). This is a completely new experience for me. I want per-unit royalties, but I don't have the slightest idea what the standard amount is. I also want to be compensated for my time, so that's an upfront R&D cost for the company I'm negotiating with, but distribution cost to them is presumably virtually nothing once it's out there. But then there's support costs. What sorts of deals have you folks negotiated?

• Is it wrong to use a boolean parameter to determine behavior?

  - by Ray

  I have seen a practice from time to time that "feels" wrong, but I can't quite articulate what is wrong about it. Or maybe it's just my prejudice. Here goes: A developer defines a method with a boolean as one of its parameters, and that method calls another, and so on, and eventually that boolean is used, solely to determine whether or not to take a certain action. This might be used, for example, to allow the action only if the user has certain rights, or perhaps if we are (or aren't) in test mode or batch mode or live mode, or perhaps only when the system is in a certain state. Well there is always another way to do it, whether by querying when it is time to take the action (rather than passing the parameter), or by having multiple versions of the method, or multiple implementations of the class, etc. My question isn't so much how to improve this, but rather whether or not it really is wrong (as I suspect), and if it is, what is wrong about it.

• Why is 2^16 a "special" number?

  - by javamonkey79

  OK, I feel stupid asking this - but in Jeff's article: Getting the Interview Phone Screen Right and originally stated in the 5 essential phone screen questions: They shouldn't stare blankly at you when you ask with 2^16 is. It's a special number. They should know it. I've been a developer\software engineer\code monkey\whatever for a little while now, and I don't think I've ever come across this. I mean, I can certainly count binary values do basic operations on them, etc, etc. But I don't see what is "special" about this value.

• Setting up Developers Conference

  - by Darknight

  In our local city in the UK, there are as far as I am aware no developer conferences. I am confident that our region has many professional developers as well as many graduating students whom who really benefit from a conference. I would like to ask the following questions: What steps or advice would one take if the task was given to set up a local developers conference? What would the costing look like? (excluding building/hosting of website(s)) How would one build interest and promote this? How would I approach, Local Companies & Universities to collaborate with them? I'm not just aiming this question to users who may have experience in setting up such conferences (but are highly welcome). Rather how would you attack this if you was tasked with this?

• Introduction to JBatch

  - by reza_rahman

  It seems batch processing is moving more and more into the realm of the Java developer. In recognition of this fact, JBatch (aka Java Batch, JSR 352, Batch Applications for the Java Platform) was added to Java EE 7. In a recent article JBatch specification lead Chris Vignola of IBM provides a high level overview of the API. He discusses the core concepts/motivation, the Job Specification Language, the reader-processor-writer pattern, job operator, job repository, chunking, packaging, partitions, split/flow and the like. You can also check out the official specification yourself or try things out with the newly released Java EE 7 SDK.

• Passing functions into other functions as parameters, bad practice?

  - by BlueHat

  We've been in the process of changing how our AS3 application talks to our back end and we're in the process of implementing a REST system to replace our old one. Sadly the developer who started the work is now on long term sick leave and it's been handed over to me. I've been working with it for the past week or so now and I understand the system, but there's one thing that's been worrying me. There seems to be a lot of passing of functions into functions. For example our class that makes the call to our servers takes in a function that it will then call and pass an object to when the process is complete and errors have been handled etc. It's giving me that "bad feeling" where I feel like it's horrible practice and I can think of some reasons why but I want some confirmation before I propose a re-work to system. I was wondering if anyone had any experience with this possible problem?

• How to Enable SideLoading in a SharePoint Site

  - by Damon Armstrong

  I was trying to deploy a SharePoint App for the first time and ran into an error about SideLoading not being enabled on the site. The solution is fairly simple – you just have enable the Developer feature on the site.  Unfortunately, it’s a hidden feature so you have to do it through PowerShell.  While searching the internet for the command to enable the feature I kept running into really long scripts that seemed overly complicated.  Fortunately, Jeff (a friend at work) sent me this snippet that is very concise and does the job: Enable-SPFeature e374875e-06b6-11e0-b0fa-57f5dfd72085 –url http://yoursharepointbox/site/ Obviously, you will need to update the URL to match your environment!
