• Developing professionally for iOS, Android and web - an insight

  - by Scott Roberts

  This is not really a question on how to develop all three, I know various cross platform ways and so on. But I more want to know from developer standpoint how hard it is to basically develop iOS, Android and web apps? I am currently in my first job as a mobile/web developer. I have already developed my first iPhone/iPad app and now I have to develop the app for android because the web version I tried just didn't perform as well as needed and web databases just did not seem to make the cut. But I am not sure it's possible to be good at developing all 3 in terms of remembering all the api's etc. I wouldn't say I have an issue with the programming languages just how to use the api's for the various platforms. Also, all the other languages I look at, in my spare time, just feel like I am spreading myself to thin. Is it feasible for one person to be developing ios, android and web apps? Should I think about reducing it to iOS and web based apps? I develop everything by myself, so I have no one to discuss what the best solutions are for everything and I am just trying to workout as I go along. So any cross platform developers out there? Do companies have different teams for different platforms? Any insight would just help me get my head together. Hopefully this question makes sense.

• Microsoft Silverlight Analytics Framework - Day 2 Part 2 of MIX 2010

  - by GeekAgilistMercenary

  I went to the session on Microsoft Silverlight Analytics Framework (MSAF) today while here at MIX 2010.  It was a great walk through the features, ideas, and what the end goal is.  Michael Scherotter did a great job of lining up the ideas, intentions, and the functional ideas behind the framework. The framework is built around the Silverlight Behaviors.  If you aren't sure what behaviors are, check out these entries from Nikhilk.net Silverlight Behaviors, Silverlight 3 Drag Behavior, An Introduction to Behaviors, Triggers, and Actions, and of course the MSDN Documentation on the matter. Some of the key features of the framework is to support out-of-browser scenarios, which works perfectly with out Webtrends DX Web Services.  Offline scenarios, which again, we have worked toward supporting at Webtrends DC Web Services via caching and other criteria as needed.  Another feature that I was really stoked about is the Microsoft Expression Blend integration that removes the need for coding, thus simplifying the addition of analytics components based on events or other actions within a Silverlight Application.  This framework also easily supports A/B Testing (again, something we do quit a bit of at Webtrends with Webtrends Optimize. The last thing I really wanted to point out was the control support that this framework has support in already from Telerik RadControls, Smooth Streaming Media Element, and Microsoft Silverlight Media Framework Player 1.0.  These are implemented with behaviors and handlers exposed via MEF (Managed Extensibility Framework). All in all, great second day, great analytics framework for Silverlight, and great presentation.  Until tomorrow, adieu. For this original entry and all sorts of other technical gibberish I write, check out my other blog Agilist Mercenary.

• Google bots are severely affecting site performance

  - by Lynn

  I have an aggregate site on a linux server that pulls in feeds from a universe of about 2,000 blogs. It's in Wordpress 3.4.2 and I have a cron job that is staggered to run five times an hour on another server to pull in the stories and then publish them to the front page of this site. This is so I didn't put too much pressure all on one server. However, the Google bots, which visit a few times every hour bring the server to its knees in the morning and evenings when there is an increase in traffic on the site. The bots have something like 30,000 links to follow at this point. How do I throttle the bots to simply grab the new stories off the front page and stop there? EDIT- Details of my server configuration: The way we have this set up is the server that handles all the publishing is an unmanaged instance via AWS. It mounts the NFS server and connects to the RDS to update content, etc. You get to this publishing instance via a plugin that detects the wp-admin link and then redirects you into there. The front end app server also mounts the NFS and requests data from the RDS. It is the only one that has the WP Super Cache on it.... The OS is Ubuntu on the App server and the NFS runs CentOs. The front end is Nginx and the publishing server is Apache.

• Is my first employer expecting too much?

  - by priyank patel

  This is my first job as a programmer. I am working using the followig technologies: ASP.NET C# HTML CSS Javascript JQuery I work for a firm which develops software for small banking firms. Currently they have their software running in 100 firms. Their software is developed in Visual Fox Pro. I was hired to develop an online version of this software. I am the only developer. My boss is another developer, the only other developer in the firm. Therefore, my employer has a total of two developers. My boss does not have any experience with .NET development. I have been working on this project for 8 months. The progress is there, but has been very slow. I try my best to do what my boss asks. But the project just seems too ambitious for me. The company has not done have any planning for the project. They just ask me to develop what their older software provides. So I have to deal with front end, back end, review code, design architecture, and more. I have decided to give my best. I try a lot. But the project sometimes just seems to be overwhelming. Question: Is it normal for a beginner programmer to be in this place? Are my employers just expecting too much of a new programmer? As a programmer, am I lacking skills one needs to deal with this? I always feel the need to work in at least a small team, if not big one. I am just not able judge my condition. Also I am paid very low salary. I do work on Saturday as well. Please, help to clarify my judgment. Any suggestions are welcome.

• Can I use access used by Visual Basic for building a database [on hold]

  - by user3413537

  I am the only programmer where I work (summer job) and I am a student with only a few years of programming experience. So I was asked to build a database and I am very excited about this project because hopefully I can learn a lot from this. Using this database my manager is supposed to be able to assign work (dealing with businesses) to different people within the company using an interface (all workers have a shared drive). When workers are done with that paperwork related to the business, they can check off that its done, add comments at the bottom of the interface, and then move on to the next business. The only experience I've had with databases is some querying with SQL, and I've built GUI interfaces with JAVA. The information on the interface will be populated from Excel so workers know what businesses they are dealing with. I've done some research and I believe the best way to build this would be building a GUI using Microsoft Visual Studio (Visual Basic) first, then figuring out a way to populate the Interface from Excel. Also because the data is pretty straight forward and not complicated I will be using MS Access to store and track the database. I know this won't be easy, but for all you geniuses out there, is this on the right path? Thanks.

• Is It Time To Specialize?

  - by Tim Murphy

  Originally posted on: http://geekswithblogs.net/tmurphy/archive/2013/06/18/is-it-time-to-specialize.aspx Over my career I have made a living as a generalist.  I have been a jack of all trades and a master of none.  It has served me well in that I am able to move from one technology to the other quickly and make myself productive.  Where it becomes a problem is deep knowledge.  I am constantly digging for the things that aren’t basic knowledge.  How do you make a product like WCF or Windows RT do more than just “Hello World”? As an architect I need to be a jack of all trades.  This is what helps me to bring the big picture of a project into focus for developers with different skills to accomplish the goals of the project. It is a key when the mix technologies crosses Windows, Unix and Mainframe with different languages and databases.  The larger the company that the project is for the more likely this scenario will arise. As a consultant and a developer I need to have specialized skills in order to get the job done efficiently.  if I have a SharePoint or Windows Phone project knowing the object model details and possible roadblocks of the technology allow me to stay within budgets as well as better advise the client on technology decisions. What is the solution?  Constant learning and associating with developers who specialize in a variety of technologies is the best thing you can do.  You may have thought you were done with classes when you left college, but in this industry you need to constantly be learning new products and languages.  The ultimate answer is you must generally specialize.  Learn as many subject areas as possible, but go deep when ever you can.  Sleep is overrated.  Good luck. del.icio.us Tags: software development,software architecture,specialization,generalist

• Forum software alternative to phpBB3

  - by Fernando

  I've been using phpBB3 for quite some time now. It seems to me this forum software hasn't evolved at all in all these years. Installing mods is a hassle, updating it to a newer version a real pain in the arse and moderating is not intuitive at all. Besides, I find there's just no way to stop spam on it. Lots of web software have made a great job controlling spam, but phpBB3 still doesn't, at least not without too much complex and tedious work. Since my last attempt to update to the latest version broke it, I'm finally fed up with it, and decide I'm not wasting a minute more in mantaining such a beast. I'm looking for a free software (free as in free beer and free as in free speech) alternative. So SMF is not an alternative at the moment. The most important feature I'm looking for is there must be a script to migrate all of the current phpBB users and posts into the new system. Out of all the alternatives out there, does any of them support these features? Which one do you recommend?

• How to find location of installed library

  - by Raven

  Background: I'm trying to build my program but first I need to set up libraries in netbeans. My project is using GLU and therefore I installed libglu-dev. I didn't note location where the libraries were located and now I can't find them.. I've switched to Linux just a few days ago and so far I'm very content with it, however I couldn't google this one out and becoming frustrated.. Is there way to find out where files of package were installed without running installation again? I mean if I got library xxx and installed it some time ago, is there somecommand xxx that will print this info? I've already tried locate, find and whereis commands but either I'm missing something or I just can't do it correctly.. for libglu, locate returns: /usr/share/bug/libglu1-mesa /usr/share/bug/libglu1-mesa/control /usr/share/bug/libglu1-mesa/script /usr/share/doc/libglu1-mesa /usr/share/doc/libglu1-mesa/changelog.Debian.gz /usr/share/doc/libglu1-mesa/copyright /usr/share/lintian/overrides/libglu1-mesa /var/lib/dpkg/info/libglu1-mesa:i386.list /var/lib/dpkg/info/libglu1-mesa:i386.md5sums /var/lib/dpkg/info/libglu1-mesa:i386.postinst /var/lib/dpkg/info/libglu1-mesa:i386.postrm /var/lib/dpkg/info/libglu1-mesa:i386.shlibs Other two commands fail to find anything. Now locate did it's job but I'm sure none of those paths is where the library actually resides (at least everything I was linking so far was in /usr/lib or usr/local/lib). The libglu was introduced just as example, I'm looking for general solution for this problem.

• Programming as a minor

  - by Tomas Cokis

  Hello Everyone! I've never asked a question here at programmers, and for reasons which will become obvious later I've never answered one here, but I do poke around in short bursts. Anyway, I'm 15 right now, and I've been programming in C++ for 4 years, just working on my own projects that are aim so high as to never be finished. I've been working on a single project for the last year, and every 3 months, I add a new system into it. It might be a value tabling directory enabled log system, or a render system, or a class to load up xml files, whatever it is, I don't mind too much that the overall project (a 3d engine) isn't ever going to get finished, I just get some satisfaction from getting what I have done building and running. I don't know what I want to do when I grow up, although I suspect I'll go into some form of engineering, but I was interested in knowing if I do choose to go into a career as a developer, what kind of material I could look at to push myself up and get myself experience that might help my career later. I'm not talking about books in particular, I'm more interested in subjects areas that will get me access to good job opportunities, or that will give me a hand-up if I do computer science and software related courses at uni. One of the things I was thinking of doing was designing some of the logic gate components of a small computer - which I started briefly over the holidays, working out integer addition, subtraction and multiplication. That kind of stuff interests me, but is it really useful - or more useful then just more programming? But anyway, Any advice? Should I continue on my perpetual 3d engine? Are there any other projects or particular accomplishments that would help my education? Perhaps I should mention that I live in Perth, Australia, so local software companies are likely to be more scarce then usual.

• SharePoint Web Part Constructor Fires Twice When Adding it to the Page (and has a different security

  - by Damon

  We had some exciting times debugging an interesting issue with SharePoint 2007 Web Parts.  We had some code in staging that had been running just fine for weeks and had not been touched or changed in about the same amount of time.  However, when we tried to move the web part into a different staging environment, the part started throwing a security exception when we tried to add it to a page.  After a bit of debugging, we determined that the web part was throwing the exception while trying to access the SPGroups property on the SharePoint site.  This was pretty strange because we were logged in as an admin and the code was working perfectly fine before.  During the debugging process, however, we found out that the web part constructor was being fired twice.  On one request, the security context did not seem to have everything it needed in order to run.  On the other request, the security context was populated with the user context with the user making the request (like it normally is).  Moving the security code outside of the constructor seems to have fixed the issue. Why the discrepancy between the two staging environments?  Turns out we deployed the part originally, then deployed an update with the security code.  Since the part was never "added" to the page after the code updates were made (we just deployed a new assembly to make the updates), we never saw the problem.  It seems as though the constructor fires twice when you are adding the web part to the page, and when you run the web part from the web part gallery.  My only thought on why this would occur is that SharePoint is instantiating an instance to get some information from it - which is odd because you would think that would happen with reflection without requiring a new object.  Anyway, the work around is to just not put anything security related inside the constructor, or to do a good job accounting for the possibility of the security context not being present if you are adding the item to the page.

• Codifying a natural language requirements spec

  - by ProfK

  I have a fairly technical functionality requirements spec, expressed in English prose, produced by my project manager. It is structured as a collection of UI tabs, where the requirements for each tab are expressed as a lit of UI fields and a list of business rules for the tab. Most business rules are for UI fields on a tab, e.g: a) Must be alphanumeric, max length 20. b) Must be a dropdown, with values from table x. c) Is mandatory. d) Is mandatory under certain conditions, e.g. another field is just populated, or has a specific value. Then other business rules get a little more complex. The spec is for a job application, so the central business object (table) is the Applicant, and we have several other tables with one-to-many relationships with applicant, such as Degree, HighSchool, PreviousEmployer, Diploma, etc. e) One such complex rule says a status field can only be assigned a certain value if a many-side record exists in at least one of the many-side tables. E.g. the Applicant has at least one HighSchool or at least one Diploma record. I am looking for advice on how to codify these requirements into a more structured specification defined in terms of tables, fields, and relationships, especially for the conditional rules for fields and for the presence of related records. Any suggestions and advice will be most welcome, but I would be overjoyed if i could find an already defined system or structure for expressing things like this.

• Are project managers useful in Scrum?

  - by Martin Wickman

  There are three roles defined in Scrum: Team, Product Owner and Scrum Master. There is no project manager, instead the project manager job is spread across the three roles. For instance: The Scrum Master: Responsible for the process. Removes impediments. The Product Owner: Manages and prioritizes the list of work to be done to maximize ROI. Represents all interested parties (customers, stakeholders). The Team: Self manage its work by estimating and distributing it among themselves. Responsible for meeting their own commitments. So in Scrum, there is no longer a single person responsible for project success. There is no command-and-control structure in place. That seems to baffle a lot of people, specifically those not used to agile methods, and of course, PM's. I'm really interested in this and what your experiences are, as I think this is one of the things that can make or break a Scrum implementation. Do you agree with Scrum that a project manager is not needed? Do you think such a role is still required? Why?

• How can dev teams prevent slow performance in consumer apps?

  - by Crashworks

  When I previously asked what's responsible for slow software, a few answers I've received suggested it was a social and management problem: This isn't a technical problem, it's a marketing and management problem.... Utimately, the product mangers are responsible to write the specs for what the user is supposed to get. Lots of things can go wrong: The product manager fails to put button response in the spec ... The QA folks do a mediocre job of testing against the spec ... if the product management and QA staff are all asleep at the wheel, we programmers can't make up for that. —Bob Murphy People work on good-size apps. As they work, performance problems creep in, just like bugs. The difference is - bugs are "bad" - they cry out "find me, and fix me". Performance problems just sit there and get worse. Programmers often think "Well, my code wouldn't have a performance problem. Rather, management needs to buy me a newer/bigger/faster machine." The fact is, if developers periodically just hunt for performance problems (which is actually very easy) they could simply clean them out. —Mike Dunlavey So, if this is a social problem, what social mechanisms can an organization put into place to avoid shipping slow software to its customers?

• Knowledge Transfer without a Plan

  - by Kanini

  Hello...We are doing work for a particular client managing their CRM implementation. (The CRM itself is a product which has been largely customized to suit my client's needs). Now, they want us to manage the Oracle batch jobs/ETL as well. And for this, they are ready to provide us with Knowledge Transfer. (The Oracle batch jobs/ETL is managed in-house by the client now). After much persuasion, I got one of the Project Lead (designation-wise) to email the client asking for a KT Plan. (The Project Lead kept saying that they have never had KT plans before and all that for which I offered I will draft a template and even that was rejected!). Email from us to them - Can you please share with us the KT Plan? Response from them - Not sure what is expected from my side? The KT is planned for tomorrow from 11 am onwards where Functional knowledge of existing ETL Data migration package will be shared. How do you handle such a client? Most likely what is going to happen is this. The person who is giving the KT will say that I have given complete Knowledge Transfer and we will go back and say that "No, this was not covered. For this, they provided an overview alone and left it at that!" and so on... My Project Lead also did not respond to that email. He just said that the meeting is scheduled to happen at 11 AM (basically repeating whatever the email said and left for the day!). What could I possibly do? PS: Look for another job is a very helpful answer, but I am not looking for it. :-)

• BizTalk HL7 Receive Pipeline Exception

  - by Paul Petrov

  If you experience sequence of errors below with BizTalk HL7 MLLP receive ports you may need to request a hotfix from Microsoft. Knowledge base article number is 2454887 but it’s still not available on the KB site. The hotfix is recently released and you may need to open support ticket to get to it. It requires three other hotfixes installed: ·         970492 (DASM 3.7.502.2) ·         973909 (additional ACK codes) ·         981442 (Microsoft.solutions.btahl7.mllp.dll 3.7.509.2) If the exceptions below repeatedly appear in the event log you most likely would be helped by the hotfix: Fatal error encountered in 2XDasm. Exception information is Cannot access a disposed object. Object name: 'CEventingReadStream'. There was a failure executing the receive pipeline: "BTAHL72XPipelines.BTAHL72XReceivePipeline, BTAHL72XPipelines, Version=1.3.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" Source: "BTAHL7 2.X Disassembler" Receive Port: "ReceivePortName" URI: "IPAddress:portNumber" Reason: Cannot access a disposed object. Object name: 'CEventingReadStream'. The Messaging Engine received an error from transport adapter "MLLP" when notifying the adapter with the BatchComplete event. Reason "Object reference not set to an instance of an object." We’ve been through a lot of troubleshooting with Microsoft Product Support and they did a great job finding an issue and releasing a fix.

• 24 Hours of PASS scheduling

  - by Rob Farley

  I have a new appreciation for Tom LaRock (@sqlrockstar), who is doing a tremendous job leading the organising committee for the 24 Hours of PASS event (Twitter: #24hop). We’ve just been going through the list of speakers and their preferences for time slots, and hopefully we’ve kept everyone fairly happy. All the submitted sessions (59 of them) were put up for a vote, and over a thousand of you picking your favourites. The top 28 sessions as voted were all included (24 sessions plus 4 reserves), and duplicates (when a single presenter had two sessions in the top 28) were swapped out for others. For example, both sessions submitted by Cindy Gross were in the top 28. These swaps were chosen by the committee to get a good balance of topics. Amazingly, some big names missed out, and even the top ten included some surprises. T-SQL, Indexes and Reporting featured well in the top ten, and in the end, the mix between BI, Dev and DBA ended up quite nicely too. The ten most voted-for sessions were (in order): Jennifer McCown - T-SQL Code Sins: The Worst Things We Do to Code and Why Michelle Ufford - Index Internals for Mere Mortals Audrey Hammonds - T-SQL Awesomeness: 3 Ways to Write Cool SQL Cindy Gross - SQL Server Performance Tools Jes Borland - Reporting Services 201: the Next Level Isabel de la Barra - SQL Server Performance Karen Lopez - Five Physical Database Design Blunders and How to Avoid Them Julie Smith - Cool Tricks to Pull From Your SSIS Hat Kim Tessereau - Indexes and Execution Plans Jen Stirrup - Dashboards Design and Practice using SSRS I think you’ll all agree this is shaping up to be an excellent event.

• The road to become a programmer [closed]

  - by user68991

  I'm looking for a 'career' change, I don't actually have a career at the moment since I haven't been able to find a job since I graduated with a degree in Materials Engineering. One of my loves has always been computers and programming, though I have never studied it seriously. When I was 11 I wrote a very basic graphical 'game' using notepad and HTML, where I drew each possible position of the main character on the different 'maze' level in MSPaint, using pictures of arrows as links to a new page with the character in a new position, and various other buttons would pop up 'search box', 'press button' etc. At the time I thought this was an amazing achievement of my programming skills. I've used a little bit of FORTRAN 90 whilst I was at university, which rekindled my interest in programming. When I was a kid I mainly used C and HTML, but only very basically as my 'game' suggests. I want to learn a new programming language, I'm not entirely sure where I want to go with it, but the number one contender at the moment is android apps. I'm looking at learning Java, but I've read that it's a difficult place to begin with; so I've also looked at learning Visual Basic, which I believe is also object oriented(?) but a little easier to understand? (not that I know what an object is anyway). Any information people could give me regarding which language to learn, and if there are any good online tutorial for that language I'd really appreciate it. Some of the tutorials I've used so far are full or jargon I can't understand. Also, I'm not afraid of maths having got an engineering degree. Thanks in advance for any help/advice. James

• How to deal with colleagues refuse to follow practices?

  - by Adrian Shum

  I was discussing with another colleague about what we should be used when an DB entity is referring to another. I don't think there is any good reason to break the practice of putting the Primary Key in the referring entity. However, one of my colleague says: "You should use a surrogate key in the entity, but it is better to put the human-readable natural key in the referring entity. As long it is unique, it is fine and it is easier when you are doing support or maintenance job" I know it will works, but obviously it is not a good practice you are putting a non-PK unique column as "foreign key", just for gaining a bit of ease in writing SQL during support as we can have less table join. Though I mentioned the his approach is conceptual incorrect, and causing problem too practically etc, he seems rather trade off correctness in data model in exchange of ease of maintenance. And he said: "I know it is not good practice, but good practice is not golden rule" Honestly I feel frustrated when dealing with something like this. I know there are always case that we should break some rule or practice, but doubtless it is not such case now. What will you when you are facing situation like this? Please assume yourself being a senior developer which is expected to contribute in misc development direction and convention.

• Introducing NFakeMail

  - by João Angelo

  Ever had to resort to custom code to control emails sent by an application during integration and/or system testing? If you answered yes then you should definitely continue reading. NFakeMail makes it easier for developers to do integration/system testing on software that sends emails by providing a fake SMTP server. You’ll no longer have to manually validate the email sending process. It’s developed in C# and IronPython and targets the .NET 4.0 framework. With NFakeMail you can easily automate the testing of components that rely on sending mails while doing its job. Let’s take a look at some sample code, we start with a simple class containing a method that sends emails. class Notifier { public void Notify() { using (var smtpClient = new SmtpClient("localhost", 10025)) { smtpClient.Send("[email protected]", "[email protected]", "S1", "."); smtpClient.Send("[email protected]", "[email protected]", "S2", ".."); } } } Then to automate the tests for this method we only need to the following: [Test] public void Notify_T001() { using (var server = new FakeSmtpServer(10025)) { new Notifier().Notify(); // Verifies two messages are received in the next five seconds var messages = server.WaitForMessages(count: 2, timeout: 5000); // Verifies the message sender Debug.Assert(messages.All(m => m.From.Address == "[email protected]")); } } The created FakeSmtpServer instance will act as a simple SMTP server and intercept the messages sent by the Notifier class. It’s even possible to verify some fields of each intercepted message and by default all intercepted messages are saved to the file system in MIME format.

• Implement Budget Allocation in DAX for Power Pivot and Tabular #powerpivot #tabular #ssas #dax

  - by Marco Russo (SQLBI)

  Comparing sales and budget, or costs and budget, is a very common operation. However, it is often the case that you have different granularities for different tables containing budget and the data to compare with. There are two ways to do that: you can limit the comparison to the granularity that is common to the two tables, or you can allocate the budget where it’s not defined. For example, if you have a budget defined by quarter and category, you might want to allocate it by month and product. In this way, you will do the comparison as you had a more granular definition of the budget, without actually having to do the manual job of allocating data (usually in an Excel worksheet!). If you want to do budget allocation in DAX, you can use the Budget Patterns we published on DAX Patterns. If you come from and MDX/OLAP background, at first you might find it hard to solve the problem of not having attribute hierarchies that helps you in propagating the budget values to lower hierarchical levels. However, I think that once you get used to DAX, you will find the behavior very predictable and easy to “debug” also for more complex allocation formula. You just have to be careful in writing the DAX formula, but probably the pattern we wrote should help you designing the right data model, without creating physical relationships to the budget table! This pattern is also based on the Handling Different Granularities scenario I discussed a couple of weeks ago.

• How popular is ITIL in the rest of the world?

  - by Oz123

  I am sorry if this question is not 100% Programming wise, I just didn't know where to ask. Consider yourself lucky if you don't know what ITIL is. You can understand from my tone I don't like it - I find ITIL the complete opposite of how IT Company should work, being too bureaucratic and complicated. In Germany, where I work, it seems to be very popular, and I have been asked in several job interviews if I know ITIL. Do you know popular is it in the rest of the world? Should I worry about ITIL or I can snub it? I must also ask my European colleagues - Why do you think is ITIL so popular? Is there a strong empirical evidence that ITIL does work? By empirical, I mean not personal experiences of the kind "We are a company that is working with ITIL...". I can hardly imagine a multi-million dollar company like Apple or Google work with ITIL, but I can also hardly see how it can benefit small companies...

• How best to deal with the frustration that you encounter at the beginning of learning to code [closed]

  - by coderboy

  I am right now a newbie on the job learning to code in Cocoa . In the beginning I decided that I would try and understand everything I was doing . But right now I just feel like a clueless wizard chanting some spells . Its all just a matter of googling the right incantation . Frequently getting stuck and having to google for answers is proving to be a major demotivator for me . I know that this will get better over time but still I feel that somewhere , somehow I'm just approaching things the wrong way . I sit there stumped and then finally just look at sample code from Apple and I go Wow ! This is so logical and well structured ! . But just reading it is not going to get me to that level . So I would like to know , how do you guys approach learning something new . Do you read the whole documentation first , or do you read sample code or maybe its just about making lots of small programs first ?

• C4C - 2012

  - by Timothy Wright

  C4C, in Kansas City, is always a fun event. At points it gets to be a pressure cooker as you zone in trying to crank out some fantastic code in just a few hours, but it is always fun. A great challenge of your skill as a software developer and for a good cause. This year my team helped The United Cerebral Palsy of Greater Kansas City organization to add online job applications and a database for tracking internal training. I keep finding that there is one key rule to pulling off a successful C4C weekend project, and that is “Keep It Simple”. Each time you want to add that one cool little feature you have to ask yourself.. Is it really necessary? and Do I have time for that? And if you are going to learn something new you should ask yourself if you’re really going to be able to learn that AND finish the project in the given time. Sometimes the less elegant code is the better code if it works. That said… You get a great amount of freedom to build the solution the way you want. Typically, the software we build for the charities will save them a lot of money and time and make their jobs easier. You are able to build the software you know you are capable of creating from your own ideas. I highly recommend any developers in the area to signup next year and show off your skills. I know I will!

• Using USB to Ethernet with Linux Ubuntu 12.04

  - by Sriram

  Being a newbie, Please excuse if the technical Jargon used is not an universally accepted one :) I have a particular device (say device A) whose USB2.0 driver is available from Linux community. Linux UBUNTU12.04 based PC is able to detect that device via the available driver. My requirement is to ensure that PC can exchange the command as well as data with the device A over TCP/IP packets (In other words, instead of just a USB Based driver, there should be a TCP/IP wrapper over the device USB driver and still does the same job as the USB driver was doing before) Bought an USB (Female) to RJ-45 adapter,connected Device A (male) USB to the USB Female end of the adapter and the Ethernet end connected to the router. PC also is connected to the same router so that both Device A and the PC have the IP address in the same subnet range. So the packets produced by the device A can be routed to the PC via some binding( not sure how I can achieve this, but conceptual idea) Here are the issues I can see as of now 1) USB to RJ-45 is just a hardware signal conversion and not a NIC in itself and hence no MAC/IP ADDRESS assigned. Can we bind a virtual NIC created in PC with this connector? 2) Any available USB TO IP command as well as data translation wrappers available? e.g. command for the device A on Ethernet converted to command for the device A on USB which is then acted upon the device as a command from the USB driver There is some missing link in my understanding and hence it would be of great help if you can bounce off some ideas on how I can take this forward so that Device A and PC exchange data over IP. Thanks and Regards, Sriram

• Learning HTML5 - Best of RSS

  - by Albers

  These are some of the best RSS feeds I've found for keeping up with HTML5. I'm doing jQuery & MVC development as well so you will find the links have a jQuery/MS angle to them. WhenCanIUse The oh-so-necessary caniuse.com, in RSS update format: http://feeds.feedburner.com/WhenCanIUse ScriptJunkie http://services.social.microsoft.com/feeds/feed/query/tag/scriptjunkieLearn/eq/ns/DiscoveryFeedTool/eq/andA good HTML, JavaScript, CSS site hosted by MS Rachel Appel's blog http://rachelappel.com/rss?containerid=13HTML5, JavaScript, and MVC links with a general MS angle Smashing Magazine http://rss1.smashingmagazine.com/feed/Really high quality articles with a focus towards the design side of the web development picture IEBlog blogs.msdn.com/b/ie/rss.aspxNo surprise - the focus is on IE10, but it is really a great resource for new browser tech. MisfitGeek http://feeds.feedburner.com/MisfitGeekJoe recently switched from MS to Mozilla. New job but he still puts out great Weekly Links summaries. The Big Web Show http://feeds.feedburner.com/bigwebshowA podcast covering web development & design topics Elijah Manor/Web Dev .NET I'm cheating on this one a little bit. Elijah is a fantastic JS & web development resource. He has a site at Web Dev .NET, but honestly these days you are better off following him on Google+ ...and you can of course sign up to follow the W3C as well, although I don't think there is an HTML5-specific RSS feed. Good luck!
