  • Is it possible to integrate Google Maps with the directions and the Transit layer into an iPhone app

    - by t4v
    Sorry if this question is obvious for some of you. I know we can link to the existing Goggle Maps app, but I would like to have an app that does not exit and provides the direction within. I intend using GTFS for public transit. On the other hand, would it be possible to plot a line inside the iPhone app the results as returned by Google Transit? (say, I send it the arrival and departure addresses) Thank you so much!

  • iPhone:How to edit and save an image on the device?

    - by user187532
    Hi, I am developing a greeting card application for iPhone. I have an image as greeting card, where-in i should allow user to add his own text, which(text) appends to that greeting image and save it on the device. Is it possible and edit an image and add some text on top of the image and save the modified image in the device storage somewhere? If anybody knows the solution, please share your ideas. Thank you.

  • How to make software development decisions based on facts

    - by Laila
    We love to hear stories about the many and varied ways our customers use the tools that we develop, but in our earnest search for stories and feedback, we'd rather forgotten that some of our keenest users are fellow RedGaters, in the same building. It was almost by chance that we discovered how the SQL Source Control team were using SmartAssembly. As it happens, there is a separate account (here on Simple-Talk) of how SmartAssembly was used to support the Early Access program; by providing answers to specific questions about how the SQL Source Control product was used. But what really got us all grinning was how valuable the SQL Source Control team found the reports that SmartAssembly was quickly and painlessly providing. So gather round, my friends, and I'll tell you the Tale Of The Framework Upgrade . <strange mirage effect to denote a flashback. A subtle background string of music starts playing in minor key> Kevin and his team were undecided. They weren't sure whether they could move their software product from .NET 2 to .NET 3.5 , let alone to .NET 4. You see, they were faced with having to guess what version of .NET was already installed on the average user's machine, which I'm sure you'll agree is no easy task. Upgrading their code to .NET 3.5 might put a barrier to people trying the tool, which was the last thing Kevin wanted: "what if our users have to download X, Y, and Z before being able to open the application?" he asked. That fear of users having to do half an hour of downloads (.followed by at least ten minutes of installation. followed by a five minute restart) meant that Kevin's team couldn't take advantage of WCF (Windows Communication Foundation). This made them sad, because WCF would have allowed them to write their code in a much simpler way, and in hours instead of days (as was the case with .NET 2). Oh sure, they had a gut feeling that this probably wasn't the case, 3.5 had been out for so many years, but they weren't sure. <background music switches to major key> SmartAssembly Feature Usage Reporting gave Kevin and his team exactly what they needed: hard data on their users' systems, both hardware and software. I was there, I saw it happen, and that's not the sort of thing a woman quickly forgets. I'll always remember his last words (before he went to lunch): "You get lots of free information by just checking a box in SmartAssembly" is what he said. For example, they could see how many CPU cores their customers were using, and found out that they should be making use of parallelism to take advantage of available cores. But crucially, (and this is the moral of my tale, dear reader), Kevin saw that 99% of SQL Source Control's users were on .NET 3.5 or above.   So he knew that they could make the switch and that is was safe to do so. With this reassurance, they could use WCF to not only make development easier, but to also give them a really nice way to do inter-process communication between the Source Control and the SQL Compare products. To have done that on .NET 2.0 was certainly possible <knowing chuckle>, but Microsoft have made it a lot easier with WCF. <strange mirage effect to denote end of flashback> So you see, with Feature Usage Reporting, they finally got the hard evidence they needed to safely make the switch to .NET 3.5, knowing it would not inconvenience their users. And that, my friends, is just the sort of thing we like to hear.

  • Windows Azure Use Case: New Development

    - by BuckWoody
    This is one in a series of posts on when and where to use a distributed architecture design in your organization's computing needs. You can find the main post here: http://blogs.msdn.com/b/buckwoody/archive/2011/01/18/windows-azure-and-sql-azure-use-cases.aspx Description: Computing platforms evolve over time. Originally computers were directed by hardware wiring - that, the “code” was the path of the wiring that directed an electrical signal from one component to another, or in some cases a physical switch controlled the path. From there software was developed, first in a very low machine language, then when compilers were created, computer languages could more closely mimic written statements. These language statements can be compiled into the lower-level machine language still used by computers today. Microprocessors replaced logic circuits, sometimes with fewer instructions (Reduced Instruction Set Computing, RISC) and sometimes with more instructions (Complex Instruction Set Computing, CISC). The reason this history is important is that along each technology advancement, computer code has adapted. Writing software for a RISC architecture is significantly different than developing for a CISC architecture. And moving to a Distributed Architecture like Windows Azure also has specific implementation details that our code must follow. But why make a change? As I’ve described, we need to make the change to our code to follow advances in technology. There’s no point in change for its own sake, but as a new paradigm offers benefits to our users, it’s important for us to leverage those benefits where it makes sense. That’s most often done in new development projects. It’s a far simpler task to take a new project and adapt it to Windows Azure than to try and retrofit older code designed in a previous computing environment. We can still use the same coding languages (.NET, Java, C++) to write code for Windows Azure, but we need to think about the architecture of that code on a new project so that it runs in the most efficient, cost-effective way in a Distributed Architecture. As we receive new requests from the organization for new projects, a distributed architecture paradigm belongs in the decision matrix for the platform target. Implementation: When you are designing new applications for Windows Azure (or any distributed architecture) there are many important details to consider. But at the risk of over-simplification, there are three main concepts to learn and architect within the new code: Stateless Programming - Stateless program is a prime concept within distributed architectures. Rather than each server owning the complete processing cycle, the information from an operation that needs to be retained (the “state”) should be persisted to another location c(like storage) common to all machines involved in the process.  An interesting learning process for Stateless Programming (although not unique to this language type) is to learn Functional Programming. Server-Side Processing - Along with developing using a Stateless Design, the closer you can locate the code processing to the data, the less expensive and faster the code will run. When you control the network layer, this is less important, since you can send vast amounts of data between the server and client, allowing the client to perform processing. In a distributed architecture, you don’t always own the network, so it’s performance is unpredictable. Also, you may not be able to control the platform the user is on (such as a smartphone, PC or tablet), so it’s imperative to deliver only results and graphical elements where possible.  Token-Based Authentication - Also called “Claims-Based Authorization”, this code practice means instead of allowing a user to log on once and then running code in that context, a more granular level of security is used. A “token” or “claim”, often represented as a Certificate, is sent along for a series or even one request. In other words, every call to the code is authenticated against the token, rather than allowing a user free reign within the code call. While this is more work initially, it can bring a greater level of security, and it is far more resilient to disconnections.

  • Pages in IE render differently when served through the ASP.NET Development server and Production Ser

    - by rajbk
    You see differences in the way IE renders your web application locally on the ASP.NET Development server compared to your production server. Comparing the response from both servers including response headers and CSS show no difference. The issue may occur because of a setting in IE. In IE, go to Tools –> Compatibility ViewSettings. The checkbox “Display intranet sites in Compatibility View” turned on forces IE8 to display the web application content in a way similar to how Internet Explorer 7 handles standards mode web pages. Since your local web server is considered to be in the intranet zone, IE uses “Compatibility View” to render your pages. While you could uncheck this setting in or propagate the change to all developers through group policy settings, a different way is described below. To force IE to mimic the behavior of a certain version of IE when rendering the pages, you use the meta element  to include a “X-UA-Compatible” http-equiv header in  your web page or have it sent as part of the header by adding it to your web.config file. The values are listed below: <meta http-equiv="X-UA-Compatible" content="IE=4"> <!-- IE5 mode --> <meta http-equiv="X-UA-Compatible" content="IE=7.5"> <!-- IE7 mode --> <meta http-equiv="X-UA-Compatible" content="IE=100"> <!-- IE8 mode --> <meta http-equiv="X-UA-Compatible" content="IE=a"> <!-- IE5 mode --> This value can also be set in web.config like so: <?xml version="1.0" encoding="utf-8"?> <configuration> <system.webServer> <httpProtocol> <customHeaders> <clear /> <add name="X-UA-Compatible" value="IE=EmulateIE7" /> </customHeaders> </httpProtocol> </system.webServer> </configuration> The setting can added in the IIS metabase as described here. Similarly, you can do the same in Apache by adding the directive in httpd.conf <Location /store> Header set X-UA-Compatible “IE=EmulateIE7” </Location> Even though it can be done on a site level, I recommend you do it on a per application level to avoid confusing the developer.

  • Mastering snow and Java development at jDays in Gothenburg

    - by JavaCecilia
    Last weekend, I took the train from Stockholm to Gothenburg to attend and present at the new Java developer conference jDays. It was professionally arranged in the Swedish exhibition hall close to the amusement park Liseberg and we got a great deal out of the top-level presenters and hallway discussions. Understanding and Improving Your Java Process Our main purpose was to spread information on JVM and our monitoring tools for Java processes, so I held a crash course in the most important terms and concepts if you want to affect the performance of your Java process. From the beginning - the JVM specification to interpretation of heap usage graphs. For correct analysis, you also need to understand something about process memory - you need space for the Java heap (-Xms for initial size and -Xmx for max heap size), but the process memory also contain the thread stacks (to a size of -Xss), JVM internal data structures used for keeping track of Java objects on the heap, method compilation/optimization, native libraries, etc. If you get long pause times, make sure to monitor your application, see the allocation rate and frequency of pause times.My colleague Klara Ward then held a presentation on the Java Mission Control product, the profiling and diagnostics tools suite for HotSpot, coming soon. The room was packed and very appreciated, Klara demonstrated four different scenarios, e.g. how to diagnose and fix latencies due to lock contention for logging.My German colleague, OpenJDK ambassador Dalibor Topic travelled to Sweden to do the second keynote on "Make the Future Java". He let us in on the coming features and roadmaps of Java, now delivering major versions on a two-year schedule (Java 7 2011, Java 8 2013, etc). Also letting us in on where to download early versions of 8, to report problems early on. Software Development in teams Being a scout leader, I'm drilled in different team building and workshop techniques, creating strong groups - of course, I had to attend Henrik Berglund's session on building successful teams. He spoke about the importance of clear goals, autonomy and agreed processes. Thomas Sundberg ended the conference by doing live remote pair programming with Alex in Rumania and a concrete tips for people wanting to try it out (for local collaboration, remember to wash and change clothes). Memory Master Keynote The conference keynote was delivered by the Swedish memory master Mattias Ribbing, showing off by remembering the order of a deck of cards he'd seen once. He made it interactive by forcing the audience to learn a memory mastering technique of remembering ten ordered things by heart, asking us to shout out the order backwards and we made it! I desperately need this - bought the book, will get back on the subject. Continuous Delivery The most impressive presenter was Axel Fontaine on Continuous Delivery. Very well prepared slides with key images of his message and moved about the stage like a rock star. The topic is of course highly interesting, how to create an infrastructure enabling immediate feedback to developers and ability to release your product several times per day. Tomek Kaczanowski delivered a funny and useful presentation on good and bad tests, providing comic relief with poorly written tests and the useful rules of thumb how to rewrite them. To conclude, we had a great time and hope to see you at jDays next year :)

  • Planning development when academic research is involved

    - by Another Anonymous User
    Dear fellow programmers, how do you do "software planning" when academic research is involved? And, on a side note, how do you convince your boss that writing software is not like building a house and it's more like writing a novel? The gory details are below. I am in charge of a small dev team working in a research lab. We started developing a software with the purpose of going public one day (i.e. sell and make money off that). Such software depends on, amongst other things, at least two independent research lines: that is, there are at least two Ph.D. candidates that will, hopefully, one day come out with a working implementation of what we need. The main software depends also on other, more concrete resources that we as developers can take care of: graphics rendering, soft bodies deformation, etc. My boss asked me to write the specifications, requirements AND a bloody GANTT chart of the entire project. Faced with the fact that I don't have a clue about the research part, and that such research is fundamental for the software, he said "make assumptions." For the clarity of the argument, he is a professor whose Ph.D. students should come up with the research we need. And he comes from a strictly engineering background: plan everything first, write down specifications and only then write down code that "it's the last part". What I am doing now: I broke down the product in features; each 'feature' is, de facto, a separate product; Each feature is built on top of the previous one; Once a feature (A) has a working prototype the team can start working on the next feature (B), while QA for is being done for A (if money allows, more people can be brought in, etc.); Features that depend on research will come last: by then, hopefully, the research part will be completed (when is still a big question) ; Also, I set the team to use SCRUM for the development of 'version 1.0', due in a few months. This deadline could be set based on reasonable assumptions: we listed all required features, we counted our availability, and we gave a reasonable estimate. So my questions, again, are: How do I make my boss happy while at the same time get something out the door? How do I write specifications for something we -the developers- have no clue whether it's possible to do or not? (We still haven't decided which libraries to use for some tasks; we'll do so when we'll need to) How do I get the requirements for that, given that there are yet no clients nor investors, just lots of interests and promises? How do I get peace in the world? I am sure at least one of my questions will be answered :) ps: I am writing this anonymously since a potential investor might backfire if this is discovered. Hope you'll understand. However I must say I do not like this mentality of 'hiding the truth': this program will likely benefit many, and not being able to talk openly about this (with my name and my reputation attached) feels like censorship. But alas, I care more about your suggestions now.

  • Windows Phone 7 development: Using isolated storage

    - by DigiMortal
    In my previous posting about Windows Phone 7 development I showed how to use WebBrowser control in Windows Phone 7. In this posting I make some other improvements to my blog reader application and I will show you how to use isolated storage to store information to phone. Why isolated storage? Isolated storage is place where your application can save its data and settings. The image on right (that I stole from MSDN library) shows you how application data store is organized. You have no other options to keep your files besides isolated storage because Windows Phone 7 does not allow you to save data directly to other file system locations. From MSDN: “Isolated storage enables managed applications to create and maintain local storage. The mobile architecture is similar to the Silverlight-based applications on Windows. All I/O operations are restricted to isolated storage and do not have direct access to the underlying operating system file system. Ultimately, this helps to provide security and prevents unauthorized access and data corruption.” Saving files from web to isolated storage I updated my RSS-reader so it reads RSS from web only if there in no local file with RSS. User can update RSS-file by clicking a button. Also file is created when application starts and there is no RSS-file. Why I am doing this? I want my application to be able to work also offline. As my code needs some more refactoring I provide it with some next postings about Windows Phone 7. If you want it sooner then please leave me a comment here. Here is the code for my RSS-downloader that downloads RSS-feed and saves it to isolated storage file calles rss.xml. public class RssDownloader {     private string _url;     private string _fileName;       public delegate void DownloadCompleteDelegate();     public event DownloadCompleteDelegate DownloadComplete;       public RssDownloader(string url, string fileName)     {         _url = url;         _fileName = fileName;     }       public void Download()     {         var request = (HttpWebRequest)WebRequest.Create(_url);         var result = (IAsyncResult)request.BeginGetResponse(ResponseCallback, request);            }       private void ResponseCallback(IAsyncResult result)     {         var request = (HttpWebRequest)result.AsyncState;         var response = request.EndGetResponse(result);           using(var stream = response.GetResponseStream())         using(var reader = new StreamReader(stream))         using(var appStorage = IsolatedStorageFile.GetUserStoreForApplication())         using(var file = appStorage.OpenFile("rss.xml", FileMode.OpenOrCreate))         using(var writer = new StreamWriter(file))         {             writer.Write(reader.ReadToEnd());         }           if (DownloadComplete != null)             DownloadComplete();     } } Of course I modified RSS-source for my application to use rss.xml file from isolated storage. As isolated storage files also base on streams we can use them everywhere where streams are expected. Reading isolated storage files As isolated storage files are opened as streams you can read them like usual files in your usual applications. The next code fragment shows you how to open file from isolated storage and how to read it using XmlReader. Previously I used response stream in same place. using(var appStorage = IsolatedStorageFile.GetUserStoreForApplication()) using(var file = appStorage.OpenFile("rss.xml", FileMode.Open)) {     var reader = XmlReader.Create(file);                      // more code } As you can see there is nothing complex. If you have worked with System.IO namespace objects then you will find isolated storage classes and methods to be very similar to these. Also mention that application storage and isolated storage files must be disposed after you are not using them anymore.

  • Simple-Talk development: a quick history lesson

    - by Michael Williamson
    Up until a few months ago, Simple-Talk ran on a pure .NET stack, with IIS as the web server and SQL Server as the database. Unfortunately, the platform for the site hadn’t quite gotten the love and attention it deserved. On the one hand, in the words of our esteemed editor Tony “I’d consider the current platform to be a “success”; it cost $10K, has lasted for 6 years, was finished, end to end in 6 months, and although we moan about it has got us quite a long way.” On the other hand, it was becoming increasingly clear that it needed some serious work. Among other issues, we had authors that wouldn’t blog because our current blogging platform, Community Server, was too painful for them to use. Forgetting about Simple-Talk for a moment, if you ask somebody what blogging platform they’d choose, the odds are they’d say WordPress. Regardless of its technical merits, it’s probably the most popular blogging platform, and it certainly seemed easier to use than Community Server. The issue was that WordPress is normally hosted on a Linux stack running PHP, Apache and MySQL — quite a difference from our Microsoft technology stack. We certainly didn’t want to rewrite the entire site — we just wanted a better blogging platform, with the rest of the existing, legacy site left as is. At a very high level, Simple-Talk’s technical design was originally very straightforward: when your browser sends an HTTP request to Simple-Talk, IIS (the web server) takes the request, does some work, and sends back a response. In order to keep the legacy site running, except with WordPress running the blogs, a different design is called for. We now use nginx as a reverse-proxy, which can then delegate requests to the appropriate application: So, when your browser sends a request to Simple-Talk, nginx takes that request and checks which part of the site you’re trying to access. Most of the time, it just passes the request along to IIS, which can then respond in much the same way it always has. However, if your request is for the blogs, then nginx delegates the request to WordPress. Unfortunately, as simple as that diagram looks, it hides an awful lot of complexity. In particular, the legacy site running on IIS was made up of four .NET applications. I’ve already mentioned one of these applications, Community Server, which handled the old blogs as well as managing membership and the forums. We have a couple of other applications to manage both our newsletters and our articles, and our own custom application to do some of the rendering on the site, such as the front page and the articles. When I say that it was made up of four .NET applications, this might conjure up an image in your mind of how they fit together: You might imagine four .NET applications, each with their own database, communicating over well-defined APIs. Sadly, reality was a little disappointing: We had four .NET applications that all ran on the same database. Worse still, there were many queries that happily joined across tables from multiple applications, meaning that each application was heavily dependent on the exact data schema that each other application used. Add to this that many of the queries were at least dozens of lines long, and practically identical to other queries except in a few key spots, and we can see that attempting to replace one component of the system would be more than a little tricky. However, the problems with the old system do give us a good place to start thinking about desirable qualities from any changes to the platform. Specifically: Maintainability — the tight coupling between each .NET application made it difficult to update any one application without also having to make changes elsewhere Replaceability — the tight coupling also meant that replacing one component wouldn’t be straightforward, especially if it wasn’t on a similar Microsoft stack. We’d like to be able to replace different parts without having to modify the existing codebase extensively Reusability — we’d like to be able to combine the different pieces of the system in different ways for different sites Repeatable deployments — rather than having to deploy the site manually with a long list of instructions, we should be able to deploy the entire site with a single command, allowing you to create a new instance of the site easily whether on production, staging servers, test servers or your own local machine Testability — if we can deploy the site with a single command, and each part of the site is no longer dependent on the specifics of how every other part of the site works, we can begin to run automated tests against the site, and against individual parts, both to prevent regressions and to do a little test-driven development In the next part, I’ll describe the high-level architecture we now have that hopefully brings us a little closer to these five traits.

  • Migrating R Scripts from Development to Production

    - by Mark Hornick
    Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 “How do I move my R scripts stored in one database instance to another? I have my development/test system and want to migrate to production.” Users of Oracle R Enterprise Embedded R Execution will often store their R scripts in the R Script Repository in Oracle Database, especially when using the ORE SQL API. From previous blog posts, you may recall that Embedded R Execution enables running R scripts managed by Oracle Database using both R and SQL interfaces. In ORE 1.3.1., the SQL API requires scripts to be stored in the database and referenced by name in SQL queries. The SQL API enables seamless integration with database-based applications and ease of production deployment. Loading R scripts in the repository Before talking about migration, we’ll first introduce how users store R scripts in Oracle Database. Users can add R scripts to the repository in R using the function ore.scriptCreate, or SQL using the function sys.rqScriptCreate. For the sample R script     id <- 1:10     plot(1:100,rnorm(100),pch=21,bg="red",cex =2)     data.frame(id=id, val=id / 100) users wrap this in a function and store it in the R Script Repository with a name. In R, this looks like ore.scriptCreate("RandomRedDots", function () { line-height: 115%; font-family: "Courier New";">     id <- 1:10     plot(1:100,rnorm(100),pch=21,bg="red",cex =2)     data.frame(id=id, val=id / 100)) }) In SQL, this looks like begin sys.rqScriptCreate('RandomRedDots',  'function(){     id <- 1:10     plot(1:100,rnorm(100),pch=21,bg="red",cex =2)     data.frame(id=id, val=id / 100)   }'); end; / The R function ore.scriptDrop and SQL function sys.rqScriptDrop can be used to drop these scripts as well. Note that the system will give an error if the script name already exists. Accessing R scripts once they’ve been loaded If you’re not using a source code control system, it is possible that your R scripts can be misplaced or files modified, making what is stored in Oracle Database to only or best copy of your R code. If you’ve loaded your R scripts to the database, it is straightforward to access these scripts from the database table SYS.RQ_SCRIPTS. For example, select * from sys.rq_scripts where name='myScriptName'; From R, scripts in the repository can be loaded into the R client engine using a function similar to the following: ore.scriptLoad <- function(name) { query <- paste("select script from sys.rq_scripts where name='",name,"'",sep="") str.f <- OREbase:::.ore.dbGetQuery(query) assign(name,eval(parse(text = str.f)),pos=1) } ore.scriptLoad("myFunctionName") This function is also useful if you want to load an existing R script from the repository into another R script in the repository – think modular coding style. Just include this function in the body of the other function and load the named script. Migrating R scripts from one database instance to another To move a set of functions from one system to another, the following script loads the functions from one R script repository into the client R engine, then connects to the target database and creates the scripts there with the same names. scriptNames <- OREbase:::.ore.dbGetQuery("select name from sys.rq_scripts where name not like 'RQG$%' and name not like 'RQ$%'")$NAME for(s in scriptNames) { cat(s,"\n") ore.scriptLoad(s) } ore.disconnect() ore.connect("rquser","orcl","localhost","rquser") for(s in scriptNames) { cat(s,"\n") ore.scriptDrop(s) ore.scriptCreate(s,get(s)) } Best Practice When naming R scripts, keep in mind that the name can be up to 128 characters. As such, consider organizing scripts in a directory structure manner. For example, if an organization has multiple groups or applications sharing the same database and there are multiple components, use “/” to facilitate the function organization: line-height: 115%;">ore.scriptCreate("/org1/app1/component1/myFuntion1", myFunction1) ore.scriptCreate("/org1/app1/component1/myFuntion2", myFunction2) ore.scriptCreate("/org1/app2/component2/myFuntion2", myFunction2) ore.scriptCreate("/org2/app2/component1/myFuntion3", myFunction3) ore.scriptCreate("/org3/app2/component1/myFuntion4", myFunction4) Users can then query for all functions using the path prefix when looking up functions. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

  • Advise on how to move from a .net developer role to a web developer role

    - by dermd
    I've been working primarily as a .net developer for the past 4 years for a financial services company. I've worked on .net 1.1, 2.0, 3.5 and have done the 3.5 enterprise app developer cert (not that that's worth a whole lot!). Before that I worked as a java developer with a bit of Flex thrown in for just over a year. My educational background is an Electronic and computer engineering degree, a higher diploma in systems analysis as well as one in web development (this was mainly java - JSP, Spring, etc) and a science masters in software design and development. I really feel like a change and would like to move to a different field to experience something different. I've done some courses in RoR and played around with it a bit in my spare time. Similarly I've done various web and mobile courses and done up some mobile webapps along with android and ios equivalents (haven't tried pushing them up to the app stores yet but may be worth tidying them up and doing that). I currently work long enough hours so find it hard to find time to work on too many side projects to get a decent portfolio together. But when I do work on the web stuff I do find it really enjoyable so think it's something I'd like to do full time. However, since my experience is pretty much all .net and financial services I find it very hard to get my foot in the door anywhere or get past a phone screen unless their specifically looking for someone with .net knowledge. What is the best way to move into a web development role without starting from scratch again. I do think a lot of the skills I have translate over but I seem to just get paired with .net jobs whenever I look around? Apart from js, jquery, html5, objective C are there any other technologies I should be looking into?

  • Article - Create a MapView in Google Maps for iOS

    - by Wallym
    With the introduction of iOS 6 in September 2012, Apple Inc. removed the map system based on Google Maps and introduced its own map system for iPhone and iPad users. The introduction of Apple Maps, like any new technology, came with its own problems. In December 2012, Google released its Google Maps SDK for iOS. (Check the Google Maps SDK for iOS page for additional documentation as new features are deployed to the product.) Google Maps for iOS has a long, solid track record, given the use of its data in Android and many years of usage. The introduction of Google Maps for iOS has resulted in a measurable increase in the number of users who have updated their existing iPhones from iOS version 5 to iOS version 6. This article will look at using Google Maps for iOS using Xamarin.iOS.Article url: http://visualstudiomagazine.com/articles/2013/06/01/how-to-use-google-maps-for-ios.asp

  • Web framework for IPad and common desktop browsers?

    - by Chris
    We are developing a web-based, commercial point-of-sale application. We'd like the same web site to work well on an Ipad as well a desktop browsers. We're looking for a web framework that makes the site look good on an IPad, but also makes the site work well in a desktop browser such as Chrome, IE, or Firefox on Windows or a Mac. I found quite a few at 18 Mobile Frameworks and Development Tools for Creating iPhone Apps Most of them, such as JQTouch, help a web site look and act more like a native IPhone application but they don't emphasize the cross platform/browser experience. The exception seems to be Sproutcore, which seems to be a full-fledged javascript MVC application framework. I did have trouble getting some of the demos to work under Chrome, but what did work looks good. What framework(s) have you actually used to develop web sites to work on an Ipad and desktop browser? If you didn't use a framework, how did you get it to work well under both environments?

  • Beta Testing iOS Application

    - by dbramhall
    I was wondering if it is advisable to get a small team of beta testers for an iOS application that will be released to the App Store. I am developing an iOS application and I have setup a beta application form however I was wondering if it is advisable to even do beta testing considering I am actively testing and using my application on all of my own iOS devices (iPad 2, 2 iPod Touches and an iPhone 4 (plus, of course iOS Simulator)) - all running various versions of iOS 4. My question is: would you advise someone to get beta testers for an iOS application and, if so, how would you advise them to go about getting testers. For those interested, my application is at http://affogato.visioa.com/

  • Mobile Apps for Hospitals?

    - by Joey Green
    I currently work for a pretty large hospital and have been dabbling in iPhone development for a couple years. The CEO is wanting to get together a group to see what mobile technology we could create. I was contacted to be the main developer. I wanted to gather some ideas of what kind of mobile apps people have seen deployed in hospitals. Not necessarily medical apps that you can get on the app store, but rather apps built specifically for a hospital. Any ideas? If this is not the appropriate forum for a question like this, can someone point me to a forum where it would be appropriate?

  • What percentage of revenue would be fair for app stores to take? [closed]

    - by Tyler Collier
    Apple takes 30% of revenue from app sales on the iPhone app store. Now Apple does the same with the Mac app store. Google also takes a 30% cut in the Android Market. These seem pretty steep. What percentage do you think would be fair and good for both you as a developer/vendor and Apple/Google? What's a happier middle ground? 20%? If the answer you give is less than 30% but you are selling apps in the app store or android market, please explain why you are willing to, and what benefits Apple and Google would see from reducing their cuts.

  • Typical text encoding+BOM, and EOL behavior on mobile devices

    - by Dan W
    Typical things to worry about when dealing with text are the BOM/signature, encoding, and the end of line (EOL) char/chars. I know that Windows often favours \r\n (CR+LF) and Mac/Linux favours \n (LF), but how about mobile devices such as the iPhone and Android? Do typical apps on those platforms favour one or the other? Also, which text encodings are mobiles most likely to use - UTF-8, iso-8859-1, or even Windows 1252 (or other default codepage) or maybe even UTF-16? And if they use UTF-8/16, are they likely to need (or require not having) a BOM/signature? What is the typical behavior here?

  • Leadership does not see value in standard process for machine configuration and new developer orientation

    - by opensourcechris
    About 3 months ago our lead web developer and designer(same person) left the company, greener pastures was the reason for leaving. Good for them I say. My problem is that his department was completely undocumented. Things have been tough since the lead left, there is a lot of knowledge both theoretical knowledge we use to quote new projects and technical/implementation knowledge of our existing products that we have lost as a result of his departure. My normal role is as a product manager (for our products themselves) and as a business analyst for some of our project based consulting work. I've taught myself to code over the past year and in an effort to continue moving forward I've taken on the task of setting my laptop up as a development machine with hopes of implementing some of the easier feature requests and fixing some of the no brainer bugs that get submitted into our ticketing system. But, no one knows how to take a fresh Windows machine and configure it to work seamlessly with our production apps. I have requested my boss, who is still in contact with the developer who left, ask them to document and create a process to onboard a new developer, software installation, required packages, process to deploy to the productions application servers, etc. None of this exists, and I'm spinning my wheels trying to get my computer working as a functional development machine. But she does not seem to understand the need for such a process to exist. Apparently the new developer who replaced the one who left has been using a machine that was pre-configured for our environment, so even the new developer could not set up a new machine if we added another developer. My question is two part: Am I wrong in assuming a process to on-board and configure a new computer to be part of our development eco-system should exist? Am I being a whinny baby and should I figure the process out and create a document on my own?

  • TDD - Outside In vs Inside Out

    - by Songo
    What is the difference between building an application Outside In vs building it Inside Out using TDD? These are the books I read about TDD and unit testing: Test Driven Development: By Example Test-Driven Development: A Practical Guide: A Practical Guide Real-World Solutions for Developing High-Quality PHP Frameworks and Applications Test-Driven Development in Microsoft .NET xUnit Test Patterns: Refactoring Test Code The Art of Unit Testing: With Examples in .Net Growing Object-Oriented Software, Guided by Tests---This one was really hard to understand since JAVA isn't my primary language :) Almost all of them explained TDD basics and unit testing in general, but with little mention of the different ways the application can be constructed. Another thing I noticed is that most of these books (if not all) ignore the design phase when writing the application. They focus more on writing the test cases quickly and letting the design emerge by itself. However, I came across a paragraph in xUnit Test Patterns that discussed the ways people approach TDD. There are 2 schools out there Outside In vs Inside Out. Sadly the book doesn't elaborate more on this point. I wish to know what is the main difference between these 2 cases. When should I use each one of them? To a TDD beginner which one is easier to grasp? What is the drawbacks of each method? Is there any materials out there that discuss this topic specifically?

  • What a web developer can learn [closed]

    - by knoxxs
    There are many things to learn in web development. You can easily find what are the most important thing that you need to learn if you want to be a webmaster. Answer to questions about how to become a web developer or a webmaster only contained limited items that someone need to master. (Some eg - a, b ) But the problem is that these resources are not complete. When I started learning web development i follow the same steps. But after learning the basic development I didn't know that I have learnt nothing, there are many more things to learn. I realized this by following blogs , Q&A sites. When I first downloaded the HTNL% Boilerplate, the issue that they have covered, some of them I haven't even heard about. I want you to just suggest what are the possible things, issues that someone can learn and why to learn. I know the answer is follow blogs and do your work you will learn with time, but with these platforms I could get some benefit out of other experiences. This question is not how to become a webmaster, but answer to this may also cover that too.
