• What modern design pattern / software engineering books for Java SE 6 do you recommend ?

  - by Scott Davies

  Hi, I am very familiar with Java 6 SE language features and am now looking for modern books that cover design patterns in Java for beginners as well as software engineering books that discuss architectures, algorithms and best practices in Java coding (sort of like the Effective C# books). I am aware of the classic GoF design patterns book, however, I'd like a more modern reference that takes advantage of the features of Java 6 SE. What books would you recommend ? Thanks, Scott

• The challenge of giving a positive No

  - by MarkPearl

  I find it ironic that the more I am involved in the software industry, the more apparent it becomes that soft skills are just as if not more important than the technical abilities of a developer. One of the biggest challenges I have faced in my career is in managing client expectations to what one can deliver and being able to work with multiple clients. If I look at where things commonly go pear shaped, one area features a lot is where I should have said "No" to a request, but because of the way the request was made I ended up saying yes. Time and time again this has caused immense pain. Thus, when I saw on Amazon that they had a book titled "The power of a positive no" by William Ury I had to buy it and read it. In William's book he explains an approach to saying No that while extremely simple does change the way a No is presented. In essence he talks of a pattern the Yes! > No > Yes? Pattern. 1. Yes! -> positively and concretely describing your core interests and values 2. No. -> explicitly link your no to this YES! 3. Yes? -> suggest another positive outcome or agreement to the other person Let me explain how I understood it. If you are working on a really important project and someone asks you to do add a quick feature to another project, your Yes! would be to the more important project, which would mean a No to the quick feature, and an option for your Yes? may be an alternative time when you can look at it.. An example of an appropriate response would be... It is really important that I keep to the commitment that I made to this customer to finish his project on time so I cannot work on your feature right now but I am available to help you in a weeks time. William then goes on to explain the type of behaviour a person may display when the no is received. He illustrates this with a diagram called the curve of acceptance. William points out that if you are aware of the type of behaviour you can expect it empowers you to stay true to your no. Personally I think reading and having an understanding of the “soft” side of things like saying no is invaluable to a developer.

• What's the best language combo for code generation?

  - by Peter Turner

  I read through Code Generation in Action but never bothered to make anything of it because Ruby just doesn't fit with my lifestyle at this juncture. The book came out more on the cusp of the C# revolution, and it said that C# "was a language designed to be generated", apparently using Ruby as the generator language. In your experience, what is the ideal combination of languages to generate the most useful code?

• Diving into Scala with Cay Horstmann

  - by Janice J. Heiss

  A new interview with Java Champion Cay Horstmann, now up on otn/java, titled  "Diving into Scala: A Conversation with Java Champion Cay Horstmann," explores Horstmann's ideas about Scala as reflected in his much lauded new book,  Scala for the Impatient.  None other than Martin Odersky, the inventor of Scala, called it "a joy to read" and the "best introduction to Scala". Odersky was so enthused by the book that he asked Horstmann if the first section could be made available as a free download on the Typesafe Website, something Horstmann graciously assented to. Horstmann acknowledges that some aspects of Scala are very complex, but he encourages developers to simply stay away from those parts of the language. He points to several ways Java developers can benefit from Scala: "For example," he says, " you can write classes with less boilerplate, file and XML handling is more concise, and you can replace tedious loops over collections with more elegant constructs. Typically, programmers at this level report that they write about half the number of lines of code in Scala that they would in Java, and that's nothing to sneeze at. Another entry point can be if you want to use a Scala-based framework such as Akka or Play; you can use these with Java, but the Scala API is more enjoyable. " Horstmann observes that developers can do fine with Scala without grasping the theory behind it. He argues that most of us learn best through examples and not through trying to comprehend abstract theories. He also believes that Scala is the most attractive choice for developers who want to move beyond Java and C++.  When asked about other choices, he comments: "Clojure is pretty nice, but I found its Lisp syntax a bit off-putting, and it seems very focused on software transactional memory, which isn't all that useful to me. And it's not statically typed. I wanted to like Groovy, but it really bothers me that the semantics seems under-defined and in flux. And it's not statically typed. Yes, there is Groovy++, but that's in even sketchier shape. There are a couple of contenders such as Kotlin and Ceylon, but so far they aren't real. So, if you want to do work with a statically typed language on the JVM that exists today, Scala is simply the pragmatic choice. It's a good thing that it's such a nice choice."

• What good books are out there on program execution models? [on hold]

  - by murungu

  Can anyone out there name a few books that address the topic of program execution models?? I want a book that can answer questions such as... What is the difference between interpreted and compiled languages and what are the performance consequences at runtime?? What is the difference between lazy evaluation, eager evaluation and short circuit evaluation?? Why would one choose to use one evaluation strategy over another?? How do you simulate lazy evaluation in a language that favours eager evaluation??

• Is "Interface inheritance" always safe?

  - by Software Engeneering Learner

  I'm reading "Effective Java" by Josh Bloch and in there is Item 16 where he tells how to use inheritance in a correct way and by inheritance he means only class inheritance, not implementing interfaces or extend interfaces by other interfaces. I didn't find any mention of interface inheritance in the entire book. Does this mean that interface inheritance is always safe? Or there are guidlines for interface inheritance?

  I'm working on a git workflow to implement in a small team. The core ideas in the workflow: there is a shared project master that all team members can write to all development is done exclusively on feature branches feature branches are code reviewed by a team member other than the branch author the feature branch is eventually merged into the shared master and the cycle starts again The article explains the steps in this cycle in detail: https://github.com/janosgyerik/git-workflows-book/blob/small-team-workflow/chapter05.md Does this make sense or am I missing something?

• For Programmers familiar with ACM API? Drawing Initials

  I came across an exercise (in the book "The Art and Science of Java" by Eric Roberts) that requires using only GArc and GLine classes to create a lettering library which draws your initials on the canvas. This should be made independent of the GLabel class. I'd like to know the correct approach to use in solving this problem. I'm not sure what I have so far is good enough (I'm thinking it's too long). The questions requires that I use a good Top-Down approach.

• Dynamic Ranking with Excel and PowerPivot

  - by AlbertoFerrari

  Ranking is useful and, in our book , I and Marco provide a lot of information about how to perform ranking with PowerPivot. Nevertheless, there is an interesting scenario where ranking can be performed without complex DAX formulas, but with just some creative Excel usage. I would like to describe it here. Let us start with some words about the scenario: we want to rank products based on sales in a year (e.g. 2002) and see how the top 10 of these products performed in the following or preceding years....(read more)

• Appointment & Booking Calendar for 2,500 Members

  - by D. K. Mason

  For this job I need a booking or appointment calendar for the WP website, so that each of the 2500+ members can manage his/her own appointments calendar. Members will set their schedules and available hours. Buyers can select one member, and book when they want to visit the member and reserve time online. Lets say our WP membership site has thousands of members each offering one service. We have 25 categories. On their profile page is his appointment or booking calendar, along with his personally created and uploaded (into S3) profile video. Website visitors should be able to easily book hours & days as desired. For now all members have a free membership. WE earn $ by bringing customers to the registered members and collecting one dollar for our service. Therefore, we need an affordable script and one that handles our members needs. We already have a paid copy of Jrox. What are those needs? Well, please register for a test account in the ENTERTAINMENT category at http://asianhighway26.com/?page_id=140 Next, pretend you are a buyer and start on the index page and select your ENTERTAINMENT category. Click on image #3 and you will receive a list of others in your traveling area. When you click VIEW DETAILS, there is where a potential customer will see the calendar and if you are available on the dates and times you are interested in doing business. We know that YOU the member will want to list your not available dates and hours. There may be other features desired but this is the most important, we believe. Our WP administrator (me) can install the main script, but each member must have some login or dashboard to manage his/her own calendar and work hours. Can you create or modify any appointment calendar software to do this? Can the jam.jrox.com software we own do this? As you can see here, we offer to pay for ideas you present that we use: asianhighway26.com/?page_id=126 D.K.

  According to Wikipedia, “why the lucky stiff was the persona of an anonymous, but prolific writer, cartoonist, musician, artist, and computer programmer”. He looks a bit like Jack Black. His book, Why’s Poignant Guide to Ruby, is a classic, though it can be hard to find since Why disappeared. If you want to learn the Ruby programming language I highly recommend Why’s Poignant Guide to Ruby. I am including a link here so that others who search for it may find it more easily.

• Phone number in meta description bad or good for local rankings NAP

  - by bybe

  Once again I'm at it with increasing people's local rankings and I've learnt so much about local rankings in the past 2 weeks it feels like my brain is gonna pop anyway, question is fairly simple for someone who engages in local rankings and I appreciate the question may be a little guess work but isn't SEO mostly guessing anyway? From what I've read and learned that Google works of a system called nap for local rankings (With many other factors but this question is purely based on NAP). For people who care about local rankings NAP stands for Name of Business / Address of Business / Phone Number for Business. Now what what I've read you don't need the whole NAP to be on one website, a P or just a N can help towards your local rankings. It's believed that NAP rewards more than just P and N for example but knowing Google they might have a diversity checker which is my concern what your get to in a moment. Now of course sites weight differently where your business is posted, it's certainly going to be more credible if your NAP details are on your national phone book than say a blog site, so taking in this consideration too. Pure Guess (Not apart of the question but none the less makes a good read on my belief). Now my guess work would make me believe that the formula would look something like (N)+(A)+(P)x(T) So (N)name would be 1 or 0 to indicate present or not So (A)dress would be 1 or 0 to indicate present or not So (P)hone would be 1 or 0 to indicate present or not So (T)rust would be 1-100 to indicate level of trust So a phone number appearing on youtube might look something like 0+0+1x95= 95 and a NAP appearing on your national phone book might look something like 1+1+1x100= 300 Please note that I'm not saying this is the sole factor and I'm sure its way more complex that this with things like other factors on the page, off the page (Reviews, Links, Clicks) and so on but its still a contributor). The Question My question is fairly simple and I'd imagine hard to impossible to have an actual definite answer to this but maybe someone has seen official wording else where on this, is it bad to include address or phone number in the Meta Description? The reason I ask is that one of my competitors has these elements in the meta descriptions and their local rankings are absolutely superb, the problem I have with this is scrap bot sites like 'Similar Too' 'Seo Rankings' and 1,000's of the other scrap box networks that scrap site and then make urls with your site information are mostly limited to your meta description what this means that your phone number, address and sometimes even your company name if the domain is exact will appear as AP, and even NAP on thousands of websites. So, is it a bad strategy to include phone number and address in meta description, everything I read into would suggest its good of course with the downside of maybe lowering quality of description for click thoughts but top rankings would increase this 10 folds anyhow..

• Obtaining positional information in the IEnumerable Select extension method

  - by Kyle Burns

  This blog entry is intended to provide a narrow and brief look into a way to use the Select extension method that I had until recently overlooked. Every developer who is using IEnumerable extension methods to work with data has been exposed to the Select extension method, because it is a pretty critical piece of almost every query over a collection of objects.  The method is defined on type IEnumerable and takes as its argument a function that accepts an item from the collection and returns an object which will be an item within the returned collection.  This allows you to perform transformations on the source collection.  A somewhat contrived example would be the following code that transforms a collection of strings into a collection of anonymous objects: 1: var media = new[] {"book", "cd", "tape"}; 2: var transformed = media.Select( item => 3: { 4: Media = item 5: } ); This code transforms the array of strings into a collection of objects which each have a string property called Media. If every developer using the LINQ extension methods already knows this, why am I blogging about it?  I’m blogging about it because the method has another overload that I hadn’t seen before I needed it a few weeks back and I thought I would share a little about it with whoever happens upon my blog.  In the other overload, the function defined in the first overload as: 1: Func<TSource, TResult> is instead defined as: 1: Func<TSource, int, TResult>   The additional parameter is an integer representing the current element’s position in the enumerable sequence.  I used this information in what I thought was a pretty cool way to compare collections and I’ll probably blog about that sometime in the near future, but for now we’ll continue with the contrived example I’ve already started to keep things simple and show how this works.  The following code sample shows how the positional information could be used in an alternating color scenario.  I’m using a foreach loop because IEnumerable doesn’t have a ForEach extension, but many libraries do add the ForEach extension to IEnumerable so you can update the code if you’re using one of these libraries or have created your own. 1: var media = new[] {"book", "cd", "tape"}; 2: foreach (var result in media.Select( 3: (item, index) => 4: new { Item = item, Index = index })) 5: { 6: Console.ForegroundColor = result.Index % 2 == 0 7: ? ConsoleColor.Blue : ConsoleColor.Yellow; 8: Console.WriteLine(result.Item); 9: }
