  • Open Source vs. Closed Source? Which one to choose? [closed]

    - by Rafal Chmiel
    So far, I was always creating open-source applications (or didn't publish them at all) because it was free for me to create a new CodePlex project, and upload everything. Couple of days ago I started wandering what kind of apps should I make, closed or open source. I can see "cons" and "pros" in both such as the ones below: Open Source: Pro, free project hosting (CodePlex is excellent for .NET app updates. ClickOnce etc) Pro, free help such as developers and designers Con, people can get your source code and (sometimes) use some of your code in their apps and make money Con, companies such as Microsoft, Twitter or Tumblr won't be looking forward in buying your project (like for example Twitter bought TweetDeck - TweetDeck being a closed source AIR application, of course) Closed Source: Pro, it's harder for people to copy your idea without the source code Pro, you're more likely to get acquired/bought by companies Con, no free hosting - you have to have a website to do so (not good for updates) Con, no free help What do you think? What do you think I should choose?

  • Data Mining Resources

    - by Dejan Sarka
    There are many different types of analyses, each one with its own pros and cons. Relational reports have a predefined structure, and end users cannot change it. They are simple to use for end users. Reports can use real-time data and snapshots of data to show the state of a report at specific points in time. One of the drawbacks is that report authoring is limited to IT pros and advanced users. Any kind of dynamic restructuring is very limited. If real-time data is used for a report, the report has a negative impact on the performance of the source system. Processing of the reports might be slow because the data comes from relational database management systems, which are not optimized for reporting only. If you create a semantic model of your data, your end users can create ad-hoc report structures. However, the development is more complex because a developer is needed to create these semantic models. For OLAP, you typically use specialized database management systems. You get lightning speed of analyses. End users can use rich and thin clients to interactively change the structure of the report. Typically, they do it graphically. However, the development of an OLAP system is many times quite complex. It involves the preparation and maintenance of an enterprise data warehouse and OLAP cubes. In order to exploit the possibility of real-time restructuring of reports, the users must be both active and educated. The data is usually stale, as it is loaded into data warehouses and OLAP cubes with a scheduled process. With data mining, a structure is not selected in advance; it searches for the structure. As a result, data mining can give you the most valuable results because you can discover patterns you did not expect. A data mining model structure is limited only by the attributes that you use to train the model. One of the drawbacks is that a lot of knowledge is needed for a successful data mining project. End users have to understand the results. Subject matter experts and IT professionals need to understand business problem thoroughly. The development might be sometimes even more complex than the development of OLAP cubes. Each type of analysis has its own place in an enterprise system. SQL Server has tools for all kinds of analyses. However, data mining is the most advanced way of analyzing the data; this is the “I” in BI. In order to get the most out of it, you need to learn quite a lot. In this blog post, I am gathering together resources for learning, including forthcoming events. Books Multiple authors: SQL Server MVP Deep Dives – I wrote an introductory data mining chapter there. Erik Veerman, Teo Lachev and Dejan Sarka: MCTS Self-Paced Training Kit (Exam 70-448): Microsoft SQL Server 2008 - Business Intelligence Development and Maintenance – you can find a good overview of a complete BI solution, including data mining, in this book. Jamie MacLennan, ZhaoHui Tang, and Bogdan Crivat: Data Mining with Microsoft SQL Server 2008 – can’t miss this book if you want to mine your data with SQL Server tools. Michael Berry, Gordon Linoff: Mastering Data Mining: The Art and Science of Customer Relationship Management – data mining from both, business and technical perspective. Dorian Pyle: Data Preparation for Data Mining – an in-depth book about data preparation. Thomas and Ronald Wonnacott: Introductory Statistics – if you thought that you could get away without statistics, then you are not serious about data mining. Jiawei Han and Micheline Kamber: Data Mining Concepts and Techniques – in-depth explanation of the most popular data mining algorithms. Michael Berry and Gordon Linoff: Data Mining Techniques – another book that explains data mining algorithms, more fro a business perspective. Paolo Guidici: Applied Data Mining – very mathematical book, only if you enjoy statistics and mathematics in general. Forthcoming presentations I am presenting two data mining related sessions during the PASS Summit in Charlotte, NC: Wednesday, October 16th, 2013 - Fraud Detection: Notes from the Field – I am showing how to use data mining for a specific business problem. The presentation is based on real-life projects. Friday, October 18th: Excel 2013 Advanced Analytics – I am focusing on Excel Data Mining Add-ins, and how to use them together with Power Pivot and other add-ins. This is the most you can get out of Excel. Sinergija 2013, Belgrade, Serbia Tuesday, October 22nd: Excel 2013 Analytics to the Max – another presentation focusing on the most advanced analytics you can get in Excel. SQL Rally Amsterdam, Netherlands Thursday, November 7th: Advanced Analytics in Excel 2013 – and again I am presenting about data mining in Excel. Why three different titles for the same presentation? I don’t know, I guess I forgot the name I proposed every time right after I sent the proposal. Courses Data Mining with SQL Server 2012 – I wrote a 3-day course for SolidQ. If you are interested in this course, which I could also deliver in a shorter seminar way, you can contact your closes SolidQ subsidiary, or, of course, me directly on addresses [email protected] or [email protected]. This course could also complement the existing courseware portfolio of training providers, which are welcome to contact me as well. OK, now you know: no more excuses, start learning data mining, get the most out of your data

  • KISS and Tell - MVVM and the ViewModelLocator

    - by Bobby Diaz
    A popular topic that comes up when talking about MVVM is the use of a ViewModelLocator and the many different ways one can be implemented.  Rather than getting into the pros and cons on when or why you should use it, I decided I would just post my version of a simple ViewModelLocator and let those who like it use it, and those who don’t, well you know…  :) First, a disclaimer.  I have not used this code in a production application, it is just something I was tossing around while reading others’ posts on the subject. 1. MainView.xaml   2. MainViewModel.cs 3. ViewModelLocator.cs   I have a codepaste of the ViewModelLocator.cs file if you are interested but don’t feel like re-typing the 50 lines of code! Enjoy!

  • Using VS12 to create and manage an Azure-SQL DB (simple tasks)

    - by Konrad Viltersten
    On occasion, I'm in a project where I need to store some information in an external DB. Usually, I create one in Azure and run some scripts that I adapt (the usual create table, create login etc.). It just struck me that there might (and definitely should) be a tool in VS that allows me to create a project for my DB, pull out some boxes to create a model of a DB schema, execute a script or two on it (possibly virtual or temporary) and then somehow push it up the cloud. Haven't found such a tool. Is there one and how do I get to it? NB. I'm not looking for an optimized or well structured schema (that's what the DB pros are for at a later stage). I'm not a DB guy nor do I aspire to become one (too old, hehe). I'll probably be satisfied with a Q&D approach.

  • General approach to isometrics

    - by MrThys
    I am currently discovering the world of isometrics, now I found out there are two approaches to creating the tilemap; Just create 2:1 ratio tile-images and draw those. Creating squares and transforming them to the 2:1 ratio. What is the general approach on developing an isometric game? Now I was wondering a few things; How do more known games like AOE1/2 do this? What are the pros/cons of both methods? Which method is preferred to be used in this day and age? Edit added more general question

  • Career choice, job offer advice

    - by ivan
    Hi, beginner developer here (around 1-1.5 years of experience). I've recently got an iOs development offer and also an opportunity to start career at embedded development (at another company). I'd be grateful for general thoughts on mobile and embedded development perspectives in a few years, just general advices, or may be links to good articles and discussions on the topic. Both choices have personal pros and cons in terms of interest, salary and what's not and I'm stuck with this atm. Also, I live in a almost purely outsorcing country (Ukraine), this probably matters too. Thank you for any help.

  • Chess as a team building exercise for software developers

    - by maple_shaft
    The last place I worked wasn't a particularly great place and there were more than a few nights where we were working late into the evening trying to meet our sprints. The team while stressed out got pretty close and people started bringing in little mind teasers and puzzles, just something we would all play around with and try to solve while a build/deploy was running for the test environment, or while we were waiting for the integration test run to finish. Eventually it turned into people bringing chess boards in and setting them at their desks. We would play by email sending each other moves in chess notation, but at a very casual pace, with games lasting sometimes two or three days. Management tolerated this when we were putting in overtime, but as things were being managed better and people weren't working much more than 40/wk, they started cracking down on this and told us that we weren't allowed to have chess boards at our desks, although they were okay with the puzzle games. What are the pros and cons in your opinion of allowing chess during software development lull time?

  • Why use flash to as content headings? Why not?

    - by Itai
    A large number of sites lately which use Flash to replace what would be simple HTML headings (h1, h2, h3). Some of them do it consistently for every header. Why would you do this? What are the pros and cons of this? This seems strange to me and really inefficient, particularly since a page can have dozens of headers. I notice this because I use Flash Block (which temporarily disables Flash), so not everyone may have seen it. Just today I landed here with 4 flash headers. I've seen dozens of such use of Flash this week alone, and I am wondering if this has some benefits.

  • SQLAuthority News – #SQLPASS 2012 Seattle Update – Memorylane 2009, 2010, 2011

    - by pinaldave
    Today is the first day of the SQLPASS 2012 and I will be soon posting SQL Server 2012 experience over here. Today when I landed in Seattle, I got the nostalgia feeling. I used to stay in the USA. I stayed here for more than 7 years – I studied here and I worked in USA. I had lots of friends in Seattle when I used to stay in the USA. I always wanted to visit Seattle because it is THE place. I remember once I purchased a ticket to travel to Seattle through Priceline (well it was the cheapest option and I was a student) but could not fly because of an interesting issue. I used to be Teaching Assistant of an advanced course and the professor asked me to build a pop-quiz for the course. I unfortunately had to cancel the trip. Before I returned to India – I pretty much covered every city existed in my list to must visit, except one – Seattle. It was so interesting that I never made it to Seattle even though I wanted to visit, when I was in USA. After that one time I never got a chance to travel to Seattle. After a few years I also returned to India for good. Once on Television I saw “Sleepless in Seattle” movie playing and I immediately changed the channel as it reminded me that I never made it to Seattle before. However, destiny has its own way to handle decisions. After I returned to India – I visited Seattle total of 5 times and this is my 6th visit to Seattle in less than 3 years. I was here for 3 previous SQLPASS events – 2009, 2010, and 2011 as well two Microsoft Most Valuable Professional Summit in 2009 and 2010. During these five trips I tried to catch up with all of my all friends but I realize that time has its own way of doing things. Many moved out of Seattle and many were too busy revive the old friendship but there were few who always make a point to meet me when I travel to the city. During the course of my visits I have made few fantastic new friends – Rick Morelan (Joes 2 Pros) and Greg Lynch. Every time I meet them I feel that I know them for years. I think city of Seattle has played very important part in our relationship that I got these fantastic friends. SQLPASS is the event where I find all of my SQL Friends and I look for this event for an entire year. This year’s my goal is to meet as many as new friends I can meet. If you are going to be at SQLPASS – FIND ME. I want to have a photo with you. I want to remember each name as I believe this is very important part of our life – making new friends and sustaining new friendship. Here are few of the pointers where you can find me. All Keynotes – Blogger’s Table Exhibition Booth Joes 2 Pros Booth #117 – Do not forget to stop by at the booth – I might have goodies for you – limited editions. Book Signing Events – Check details in tomorrow’s blog or stop by Booth #117 Evening Parties 6th Nov – Welcome Reception Evening Parties 7th Nov - Exhibitor Reception – Do not miss Booth #117 Evening Parties 8th Nov - Community Appreciation Party Additionally at few other locations – Embarcadero Booth In Coffee shops in Convention Center If you are SQLPASS – make sure that I find an opportunity to meet you at the event. Reserve a little time and lets have a coffee together. I will be continuously tweeting about my where about on twitter so let us stay connected on twitter. Here is my experience of my earlier experience of attending SQLPASS. SQLAuthority News – Book Signing Event – SQLPASS 2011 Event Log SQLAuthority News – Meeting SQL Friends – SQLPASS 2011 Event Log SQLAuthority News – Story of Seattle – SQLPASS 2011 Event Log SQLAuthority News – SQLPASS Nov 8-11, 2010-Seattle – An Alternative Look at Experience SQLAuthority News – Notes of Excellent Experience at SQL PASS 2009 Summit, Seattle Let us meet!

  • Concrete examples of Python's "only one way to do it" maxim

    - by Charles Roper
    I am learning Python and am intrigued by the following point in PEP 20 The Zen of Python: There should be one-- and preferably only one --obvious way to do it. Although that way may not be obvious at first unless you're Dutch. Could anyone offer any concrete examples of this maxim? I am particularly interested in the contrast to other languages such as Ruby. Part of the Ruby design philosophy (originating with Perl, I think?) is that multiple ways of doing it is A Good Thing. Can anyone offer some examples showing the pros and cons of each approach. Note, I'm not after an answer to which is better (which is probably too subjective to ever be answered), but rather an unbiased comparison of the two styles.

  • Choosing 3D modeling software Maya or 3D max?

    - by Kenneth J
    I've am a developer whose has spent most of my programming life developing web and business applications. I want to try my hand at something more challenging (but stay in the comfort of Visual Studio) ...perhaps XNA. Want 3D modeling software would be best for someone developing XNA? I have played with 3d MAX and Maya but never really did anything too involved. What are the pros and cons between them (in terms of game development)? Does one win out over the other for game development? Or is it pretty much just preference? I am new to game development and just trying to figure out the best tools to use before I really started. Any advice or other suggections would be greatly appreciated.

  • Web Developer or Software Engineer?

    - by dahacker89
    A question that I have been asking myself and really confused which path to take. So I need your guys help as to the pros and cons of these 2 professions in today's world. I love web applications development as the Web is the best thing to happen in this age and nearly everyone gets by on the World Wide Web. And also tend to keep learning about new technologies and about web services. On the other hand I like software engineering also for the desktop applications as I have had experience with development small scale softwares in VB.Net, Java, C++, etc. Which path has more scope and better future? Whats your view?

  • Messaging technologies between applications ?

    - by Samuel
    Recently, I had to create a program to send messages between two winforms executable. I used a tool with simple built-in functionalities to prevent having to figure out all the ins and outs of this vast quantity of protocols that exist. But now, I'm ready to learn more about the internals difference between each of theses protocols. I googled a couple of them but it would be greatly appreciate to have a good reference book that gives me a clean idea of how each protocol works and what are the pros and cons in a couple of context. Here is a list of nice protocols that I found: Shared memory TCP List item Named Pipe File Mapping Mailslots MSMQ (Microsoft Queue Solution) WCF I know that all of these protocols are not specific to a language, it would be nice if example could be in .net. Thank you very much.

  • Caching large amount of ajax returned objects

    - by ofcapl
    I'm building an application which fetches large amount of items with ajax requests via other application API. It returns me 6k - 30k js objects which are used multiple times across various application views (sorting, filtering etc.). I would like to avoid querying API every time for such big list so I decided to cache this data somehow. I was thinking about various solutions: saving it to localstorage, using some caching library (e.g. locachejs), storing in js var. I'm not an expert so I would like to hear Your suggestions about each (or one of these) solution, about its pros and cons. Every help will be very appreciated.

  • Software Design for Product Verticals and Service Verticals

    - by Rachel
    In every industry there are two verticals Product Vertical and Service Vertical, so my question is: How does design approach changes while designing Software for Product Vertical as compared to developing Software for Service Vertical ? What are the pros and cons for each case ? Also, in case of Product Vertical, How you go about designing Product or Features and what are steps involved ? Lastly, I was reading How Facebook Ships Code article and it appears that Product Managers have very little influence on how Product is developed and responsibility lies mainly with the Developer for the feature. So is this good practice and why one would go for this approach ? What would be your comment on this kind of approach ?

  • Studies of Pair Programming on Translation Projects

    - by gmletzkojr
    I am looking for information (ie, studies, metrics, etc) for pair programming when translating a project from an "older" language to a "newer" language. In this particular case, translating means line for line translation where ever possible, and only modifying the design when absolutely necessary, not when the modification would provide improved performance. I have performed pair programming in new development, and I am well aware of the pros and cons of pairing in that environment. However, I haven't been able to find any information in this particular case. Any help is appreciated.

  • Type classes or implicit parameters? What do you prefer and why? [closed]

    - by Petr Pudlák
    I was playing a bit with Scalaz and I realized that Haskell's type classes are very similar to Scala's implicit parameters. While Haskell passes the methods defined by a type class using hidden dictionaries, Scala allows a similar thing using implicit parameters. For example, in Haskell, one could write: incInside :: (Functor f) => f Int -> f Int incInside = fmap (+ 1) and the same function using Scalaz: import scalaz._; import Scalaz._; def incInside[F[_]](x: F[Int])(implicit fn: Functor[F]): F[Int] = fn.fmap(x, (_:Int) + 1); I wonder: If you could choose (i.e. your favorite language would offer both), what would you pick - implicits or type classes? And what are your pros/cons?

  • Should each app have its own database, or should small apps be merged into one?

    - by King
    We have a bunch of small to medium sized apps, each of which has its own database (MSSQL Server). There was a suggestion that we consoldate the 'related' databases into a smaller set amount of larger databases. They don't particularly share a lot of data, they would just be under a similar business group. For example, using a 'Finance' DB to hold the tables and procedures for finance apps. Would it be appropriate to use a different schema for each app? E.g. App1.SomeTable App1.SomeOtherTable AppTwo.SomeTable What are the pros and cons of this approach? What should I watch out for? Thanks

  • Wisdom of using open source code in a commercial software product

    - by Mr. Jefferson
    I'm looking at using some open source code in my ASP.NET web app (specifically dapper). Management is not a fan, because open source is seen as a risk that has bitten us before. Apparently previous developers have had to rewrite things after having open-source components fail. The pros seem to be: It does a lot of stuff for me that would otherwise involve either lots of boilerplate code or Microsoft's recommended but slower solution (Entity Framework). Cons: It's complex enough that if it were to fail suddenly in production, I would be hard pressed to fix it. However, it's in use on a much higher-traffic site than mine, so I don't think it'll end up being a high risk portion of the project. What is the consensus here? Is it unwise to use open source code in my project that I don't know/understand as well as I do my own code?

  • What is the best policy for allowing clients to change email?

    - by Steve Konves
    We are developing a web application with a fairly standard registration process which requires a client/user to verify their email address before they are allowed to use the site. The site also allows users to change their email address after verification (with a re-type email field, as well). What are the pros and cons of having the user re-verify their email. Is this even needed? EDIT: Summary of answers and comments below: "Over-verification annoys people, so don't use it unless critical Use a "re-type email" field to prevent typos Beware of overwriting known good data with potentially good data Send email to old for notification; to new for verification Don't assume that the user still has access to the old email Identify impact of incorrect email if account is compromised
