• Duplicate page content and the Google index

  - by Kit Sunde

  I have a static pages with dynamically expanding content that google is indexing. I also have deep links into virtually duplicate pages which will pre-expand the relevant section of content into the relevant section. It seems like Google is ignoring all my specialized pages and not putting them in the index. Even after going through web-masters tools, crawling and submitting them to the index manually. I also use the google API for integrating search on the site, and the deep linked pages won't show up. Is there a good solution for this?

• Slow in the Application, Fast in SSMS? Understanding Performance Mysteries

  When I read various forums about SQL Server, I frequently see questions from deeply mystified posters. They have identified a slow query or stored procedure in their application. They cull the SQL batch from the application and run it in SQL Server Management Studio (SSMS) to analyse it, only to find that the response is instantaneous. At this point they are inclined to think that SQL Server is all about magic. A similar mystery is when a developer has extracted a query in his stored procedure to run it stand-alone only to find that it runs much faster – or much slower – than inside the procedure.

• Software Engineering: Off to a Bad Start?

  - by Bob Rhubart

  The opening remarks for Real Software Engineering, Living Social developer Glenn Vanderburg's keynote presentation at QCon 2012 in San Francisco, include this: The people who started the software engineering field and movement, from the very beginning, misunderstood two very important things: software and engineering. And as a result, the field went off in the wrong direction from the very start, and legitimized certain ways of doing things and certain paths of research that really have not been very fruitful. Vanderburg's presentation is fascinating, often funny, and well worth watching, especially in light of how cloud computing and other technological shifts are redefining IT roles.

• Stores Still Matter In The World Of E-Commerce

  - by Michael Hylton

  You may think that more and more consumers are moving their purchasing to the Web or mobile device.  However, according The NPD Group, Inc., a leading market research company, 15-20 percent of consumers in 2011 checked out products in stores before buying online, or called “showrooming”, for product categories like stand mixers, electric knives, sewing machines, and some floor cleaners. Other categories like power tools, hairsetters, and robotic vacuums are now beginning to show signs of the “showrooming” trend as well. It is doubly important to present a consistent, personalized, and relevant shopping experience for your customers, no matter whether they interact with you in-person in your store, with your sales agents or call center agents, over the Web, or using a mobile device.  Your goal is to make that experience across touchpoints as seamless as possible.

• Editing assemblies using ReflexIL

  - by nmarun

  I have known ReflexIL for quite some time, so I thought I’ll write a line or two about this simple and yet power tool. This tool runs as a plug-in for Red Gate’s Reflector . I’m not sure if I can cover all the features of this tool, but there are a couple that I really liked that we’ll just see those. In order to get it working, you unzip the contents of the file to some folder. In Reflector, under Tools->Add-Ins add the path to the Reflexil.Reflector.dll. And, you’re set. To bring up the add...(read more)

• How can I fix unreliable Unity startup?

  - by Vagrant232

  When I log in, either Unity loads perfectly or it just doesn't; all I see is my desktop background. Commands don't seem to work and I can't switch to the terminal view. No matter how long I wait, Unity doesn't start. I never had this issue with Oneiric Ocelot. Other GUIs such as GNOME 3.4 don’t seem to be having that issue. I've got MyUbuntu, Ubuntu Tweaks, CompizConf and other tweaking tools installed. Could they be causing the problem? If not, what should I do? I'd really like to use Unity again. Thanks in advance!

• Interface hierarchy design for separate domains

  - by jerzi

  There are businesses and people. People could be liked and businesses could be commented on: class Like class Comment class Person implements iLikeTarget class Business implements iCommentTarget Likes and comments are performed by a user(person) so they are authored: class Like implements iAuthored class Comment implements iAuthored People's like could also be used in their history: class history class Like implements iAuthored, iHistoryTarget Now, a smart developer comes and says each history is attached to a user so history should be authored: interface iHistoryTarget extends iAuthored so it could be removed from class Like: class Person implements iLikeTarget class Business implements iCommentTarget class Like implements iHistoryTarget class Comment implements iAuthored class history interface iHistoryTarget extends iAuthored Here, another smart guy comes with a question: How could I capture the Authored fact in Like and Comment classes? He may knows nothing about history concept in the project. By scalling these kind of functionallities, interfaces may goes to their encapsulated types which cause more type strength, on the other hand explicitness suffered and also code end users will face much pain to process. So here is the question: Should I encapsulate those dependant types to their parent types (interface hierarchies) or not or explicitly repeat each type for every single level of my type system or ...?

• One subdomain is not working

  - by BFTrick

  Hello there, My main domain works just fine - www.example.com and a subdomain set up by another developer works as well - sub1.example.com. But when I try to set another subdomain up I go through the process everything seems to work. The software creates the default files where the subdomain files should go. But when I try to browse there it doesn't work. My host uses Plesk to do all of the hosting stuff. What do you think the problem is? I doubt it is some sort of cache issue because I had problems on my phone which I tried after problems on the pc. Maybe for some reason Plesk needs time to set this up? I have used Cpanel before and that works instantly.

• Macro to Add using System.Linq

  - by Aligned

  I have Visual Studio 2010 setup to remove and sort settings on save with the Power Commands extensions. This is great, but sometimes it removes the using System.Linq at the top. I also find myself scrolling to the top to add the using when I first add System.Linq. So I wrote a quick macro to do it for me. Sub AddUsingLinq()        DTE.ActiveDocument.Selection.StartOfDocument()        DTE.ActiveDocument.Selection.StartOfLine(vsStartOfLineOptions.vsStartOfLineOptionsFirstText)        DTE.ActiveDocument.Selection.Text = "using System.Linq;"        DTE.ActiveDocument.Selection.NewLine()        DTE.ExecuteCommand("Edit.FormatDocument")        DTE.ExecuteCommand("Edit.RemoveAndSort")        DTE.ActiveDocument.Save() DTE.ExecuteCommand("View.NavigateBackward")    End SubHook this up to a shortcut (tools -> options -> keyboard, I chose ctrl + x, c) and you'll be moving faster than ever.

• DotNetNuke is a Gartner Cool Vendor in 2010!

  When I originally released DotNetNuke way back in 2002, I must admit that I never could have imagined the impact it would have on the technology landscape.

• Too much to learn, dealing with overwhelming varieties of technologies [closed]

  - by zhenka

  I am about to graduate, and I am already working as a web developer in our library IT department. When I look at job postings I am absolutely overwhelmed by the sheer variety of technologies out there. Some companies care about math + algorithms + data structures. Some care about experiences in technology stack XYZ. SQL, css, html, frameworks, javascript, design patterns etc.. etc... etc... At some point I realized I just need to start at mastering a foundation to become employable at a better place and go from there. But the skill-set to get me in the doors varies and I just don't have time to learn everything. How do you deal with this issue? What is the essential stack to become employable? Say in php or ror arena. Perhaps a smarter move would be to move to a technology stack with less variety like .net?

• What is approximate cost to develop iPhone/iPad app? Features described

  - by innodeasapps

  Need your help guys... I was working as an iPhone developer since last few months. And just a month ago I left the job, and now i got an offer to develop an iPhone/iPad app. I need to develop an universal app which has frames like PicFrame in which photos must adjust accordingly, with customizable frames, few photo effects like in instagram (Not exactly same but something like it) and then user can share photos on Facebook, tumbler,dropbox, etc. I might need around 30 days time to develop the desired app. Note that designing is not my part, I need to develop and test it thoroughly. I have no idea how much price should I ask to develop such app. As here is the place where we all developers meet, I feel I would get proper guidance. Thank you in advance...

• How do developers find the time to stay on top of latest technologies?

  - by u2sonderzug

  I was a freelance web developer until circa 2004 when I started going down the management route but have decided to try to get back into development again (specifically JavaScript and HTML5 web/mobile web apps) and I really get the impression to be truly good at these and similar fast moving technologies a constant amount of time is required to be set aside to invest in getting better at existing skills in addition to learning new skills. I understand right now since I am getting back into things there is a pretty steep learning curve, but seeing how good many guys are out there - the only way I see of getting up there is putting in a serious amount of time. For those working as fulltime developers, what I am trying to understand is this - on most days, how much time in the office is spent actually grinding out code compared to learning/research. I could easily spend 2-4 hours daily getting on top of the best ways to go about doing things. Do most good developers who are employed full time invest significant hours outside of work sharpening their skills? Or maybe I'm looking at all of this completely wrong?

• JEditorPane Code Completion (Part 3)

  - by Geertjan

  The final step is to put an object into the Lookup on key listening in each of the JEditorPanes, e.g., a "City" object for the CityEditorPane and a "Country" object for the CountryEditorPane. Then, within the CompletionProviders, only add items to the CompletionResultSet if the object of interest is in the Lookup. The result is that you can then have different code completions in different JEditorPanes, as shown below: I've also included the Tools | Options | Editor | Code Completion tab, so that the code completion can be customized. The full source code for the example is here: java.net/projects/nb-api-samples/sources/api-samples/show/versions/7.2/misc/CustomerApp

• Business Analyst vs. Architect [closed]

  - by suslik

  I'm a developer of a few years in the financial industry and will soon need to decide what career path to try and row towards. Broadly speaking I have two options: something more 'people' oriented like BAs, or keep coding and try to make more technical decisions like the Architects do where I currently work. Here are my perceptions right now: Business Analysts: get paid way more than devs once they do their job, it seems like they usually have no worries more likely to go REALLY high up in the organization (VPs, etc) Architects: things like certification matters (I see this as a con) called in when things go wrong more than anyone else (weekends & overtime) long career path to get to (dev - senior dev - team lead - architect) I would find the latter more intellectually rewarding, but when I look at it I just can't justify it in terms of lifestyle. Am I wrong / what am I missing? Can you really make a lot of money in a technical role or must you really get out of coding? Thank you for any constructive input.

• How to be a pro in several programming languages? [on hold]

  - by trerums

  I love PHP and C# languages and i want to be excellent in both. I like to develop PHP applications using MySQL, Nginx, Memcached and so on technologies. I also like ASP.NET MVC stack and think it's great tools. But each technology requires a lot of time to master it. The same is true for C# web stack - there is a huge amount of things to be mastered like Azure, LINQ, Entity Framework ets. Mastering PHP means knowing how it works under the hood. Mastering C# means knowing CLR implementations on a deep level, knowing MSIL etc/ Where to get time for all this? Maybe this is "jack of all trades"? What can you advice?

• Google not showing any pages from my site in the index after three months [on hold]

  - by Alex Coisman

  Despite having a sitemap and using Google Webmaster Tools, it has been over 3 months and my site has not been added to the Google index at all. Here's the site: www.famouslefthandedpeople.com As far as I know, I have done everything correctly. However, there must be something I am overlooking that is preventing Google from indexing the site. I do not have a robots.txt file, so allow/disallow isn't the issue. Although the content of the site is sparse, it is original and not duplicated internally or externally so Panda/Penguin should not be a problem. I have reviewed the answers at Why isn't my website in Google search results? and I don't think it applies here. If it matters, I am using WordPress to create the site. What other factors should I be looking at in order to troubleshoot this?
