• What should a Python developer know while learning Ruby?

  - by C J

  I have been a Python programmer for about 18 months, consisting of one internship and a few side projects, and I consider myself pretty comfortable in the language. However, there seems to be a lot of attention on Ruby in the programming field, but not a lot on Python anymore. So in learning Ruby, are there going to be Pythonic things that are just bad practices in Ruby? What should I watch out for, and what should I avoid?

• Imperative vs. component based programming [closed]

  - by AlexW

  I've been thinking about how programming and more specifically the teaching of programming is advocated amongst the community (online). Often I've heard that Ruby and RoR is an ideal platform for learning to program. I completely disagree... RoR and Ruby are based on the application of the component based paradigm, which means they are ideal for rapid application development. This is much like the MVC model in PHP and ASP.NET But, learning a proper imperative language like Java or C/C++ (or even Perl and PHP) is the only way for a new programmer to explore logic itself, and not get too bogged down in architectural concerns like the need for separation of concerns, and the preference for components. Maybe it's a personal preference thing. I rather think that the most interesting aspects to programming are the procedural bits of code I write that actually do stuff rather than the project planning, and modelling that comes about from fully object oriented engineering or simply using the MVC model. I know this may sound confused to some of you. I feel strongly though that the best way for programming to be taught is through imperative and procedural methods. Architectural (component) methods come later, if at all. After all, none of the amazing algorithms that exist were based on OOP practice! It's all procedural code when it comes to the 'magic'. OOP is useful in creating products and utilities. Algorithms are what makes things happen, and move data around, and so imperative (and/or procedural) code are what matters most. When I see programmers recommending Ruby on Rails to newbie developers, I think it's just so wrong. Just because you write less code with Ruby does not make it easier to do! It's the opposite... you have to know loads more to appreciate its succinct nature. New coders who really want to understand the nuts and bolts of coding need to go away and figure out writing methods/functions (i.e. imperative programming) and working in procedural style, in order to grasp the fundamentals, first, before looking into architectural ways of working. So, my question is: should Ruby ever be recommended as a first language? I think no (obviously)... what arguments are there for it?

• The term "interface" in C++

  - by Flexo

  Java makes a clear distinction between class and interface. (I believe C# does also, but I have no experience with it). When writing C++ however there is no language enforced distinction between class and interface. Consequently I've always viewed interface as a workaround for the lack of multiple inheritance in Java. Making such a distinction feels arbitrary and meaningless in C++. I've always tended to go with the "write things in the most obvious way" approach, so if in C++ I've got what might be called an interface in Java, e.g.: class Foo { public: virtual void doStuff() = 0; ~Foo() = 0; }; and I then decided that most implementers of Foo wanted to share some common functionality I would probably write: class Foo { public: virtual void doStuff() = 0; ~Foo() {} protected: // If it needs this to do its thing: int internalHelperThing(int); // Or if it doesn't need the this pointer: static int someOtherHelper(int); }; Which then makes this not an interface in the Java sense anymore. Instead C++ has two important concepts, related to the same underlying inheritance problem: virtual inhertiance Classes with no member variables can occupy no extra space when used as a base "Base class subobjects may have zero size" Reference Of those I try to avoid #1 wherever possible - it's rare to encounter a scenario where that genuinely is the "cleanest" design. #2 is however a subtle, but important difference between my understanding of the term "interface" and the C++ language features. As a result of this I currently (almost) never refer to things as "interfaces" in C++ and talk in terms of base classes and their sizes. I would say that in the context of C++ "interface" is a misnomer. It has come to my attention though that not many people make such a distinction. Do I stand to lose anything by allowing (e.g. protected) non-virtual functions to exist within an "interface" in C++? (My feeling is the exactly the opposite - a more natural location for shared code) Is the term "interface" meaningful in C++ - does it imply only pure virtual or would it be fair to call C++ classes with no member variables an interface still?

• Is it smart to take a year off from school to get experience?

  - by user134147

  firstly I apologize if this question is not appropriate for the site, but I've seen other similar (though slightly deviant) questions on this sight before and I know the people here are the most qualified to answer my question. Anyways, I'm currently between my sophomore and junior years at a 4 year university, and after a bit of deliberation I've decided on computer science as a major (BA, by the way, as a BS would require me to stay at least an extra year the way our program is set up). I've been interested now in programming for a few months and I've developed a passion for it in a very short time. I began learning C++, migrating to Java recently when I learned my school focuses on this language. Now, I should mention that the concept of higher education has never sat well with me, so part of my motivation for wanting to take time off is to truly challenge myself and see what I can accomplish when I actually try at something. The autodidact in me finds it difficult to focus on my passions while trying to keep a high GPA in unrelated classes. However, I understand the times we live in and therefore would plan to complete my degree after this year. So my question is whether or not the skills I learn in a year off from college could justify the time off from school. Unfortunately, I don't believe I know enough yet to gain any professional experience (internship, etc.) so I would mostly focus my time on learning Java and another language, possibly Wordpress (to gain an understanding of web programming concepts as I have not yet decided what field I want to get into, and to make some money to fund my off-year), and to delve into security concepts, which also interest me. I'm hoping I could work on projects, such as simple applications or contributions to open source software during this time to enhance my resume once I do finish school, so I can find a job out of college easier. I do not want to be the new hire who knows nothing beyond the concepts of his Java textbooks. Does anyone have any input about these thoughts of mine, or any ideas for where I should focus my studies or how high I might set the bar for my work? Thanks a lot everyone!

  I have to write a program in assembly language that will monitor temperature continuously, and I have no idea where to begin. The temperature must be displayed in BCD format, and the high and low set points will be programmed into the system. if the set points are exceeded then an alarm will be indicated. The low point is 20 degrees Celsius, and the high point is 24 degrees Celsius. Can somebody give me some hints on how to complete this task?

• Kind of lost, and I don't know where to start

  - by Rasheed Mehrinfar

  I am 16-year-old who's always been interested in the world of programming. I was wondering if anyone could point me in the right direction in what language I should learn first, and possibly suggest any good tutorials/ guides to learn from. Also, do you think it's worth it to kinda of "play around" and get familiar with a program like 3ds max, as my goal is to work in the gaming industry. Or would that just be a waste of time?

  With mobile technologies becoming increasingly popular what is happening on the server-side with most of these apps when they need to communicate with a back end? I'm used to the world of technology from 10 years ago when most resources were accessed by requesting a dynamic web page that behind the seen used a server-side language to get the information it needed from a relational database. Is this still the case, and if not, what are the big changes?

• C++ Without Source Files

  - by Snowman

  Bjarne Stroustrup mentions in his book "The C++ Programming Language, 4th Edition" that not all C++ implementations use files to store and compile code: There are systems that do not store, compile, and present C++ programs to the programmer as sets of files. (Chapter 15, page 419) Later in the chapter, he reiterates that certain implementations do not use files but he does not give any examples. How would such an environment function compared to a more common file-based environment?

• Create Custom Speech Bubbles in Silverlight.

  - by mbcrump

  I had a reader email me the following question: “How do you create Speech Bubbles in Silverlight/WPF without adding any extra .dlls? Right off the bat, I know at least two ways to create the speech bubbles that look just like the ones in comic books. Using the Callout Shapes included with Blend 4. Using the free 3rd party control named FreeBubbles (I used this before Blend 4). Unfortunately, we cannot use either of these as they will both add extra .dll’s to the project. So why wouldn’t you want to use one of those? I can think of a few reasons: You do not want to increase the size of your .XAP by including extra .dll’s. You do not have Expression Blend or the license to the use the .dll’s. You want a custom Speech Bubble that is not included in the four “Callout” Controls with Blend. Instead of using one of these methods, we will create a Speech Bubble in Blend 4 using Path element and a TextBlock. Before we get started, lets look at the Callout Shapes included with Blend 4. Using Blend 4 you can simply drag/drop these controls onto your Silverlight application and you are ready to go. We can create all of these Speech Bubbles and even some of the modern bubbles used in recent comic books. Lets get started. Start up Expression Blend 4 and select the Pen Tool. On the Art Board, start connecting the dots like I did below. You can add a color if you wish. …keep going …complete Let’s go ahead and add some text to the Speech Bubble. Drag a TextBlock from the Panel and put it directly inside the Speech Bubble. Go ahead and set the TextAlignment to Center for the TextBlock. and give it some text. At this point, you could go ahead and create a user control if you want to reuse the Speech Bubble you created. Select both the Path and the TextBlock by clicking then while holding down CTRL and then Right Click them. Select Make Into User Control. Give it a name and then Build your project. Lets create another one using the Ellipse for the older comic book style of Speech Bubbles. Drag an Ellipse to the Artboard and give it a color. Now, grab the Pen and drag a triangle like I did below. Simply drag it over a corner of the Ellipse. Select Combine then Unite and you will have a Path. At this point, you can go ahead and add a TextBlock like we did earlier. Lets go ahead and create a rounded rectangle one by adding a Rectangle to the Artboard. Go ahead and set the RadiuX and RadiusY to 25 to give it rounded edges. Let’s create another path and drag it right on top of our rounded rectangle like we did earlier. …looking good Select Combine then Unite and you will have a Path. At this point, you can go ahead and add a TextBlock like we did earlier. So let’s look at what we’ve created today using the path element and TextBlock. As you can tell, it required more work but meets the requirements. This was actually fun to do and I encourage anyone that visits my blog to send in request like this.  Subscribe to my feed

  I'd like some suggestions as to how to best go about creating an application which can generate bespoke automated e-mails? What sort of language would be the best one to use for this? (I'm currently familiar with Python and JavaScript) Any helpful frameworks? I would have thought that for this application to work well, some machine learning would have to be incorporated? (But this may be a bit too advanced for me at the moment!)

• Is IronScheme complete enough or stable enough to be worth learning?

  - by World Engineer

  IronScheme is mentioned on Wikipedia as a successor to a failed project called IronLisp, bringing Lisp to CLR and .NET, the way Clojure does for the JVM. Does anyone have experience with this language? It looks fairly complete (99%) but I'm not sure how to judge whether it's worth my time to fiddle with getting it set up or not. By stable or complete, I mean using it for actual projects rather than just fiddling with tools and Project Euler style problems.

• Why hasn't C# gained much traction within the opensource community?

  - by tmitchel2

  I'm not expecting C# to be on par with say Java or Python in the open source community, but it still surprises me just how far behind it is. 'Multi language' open source repos like google code or github have barely any C# projects in comparison to the other languages I mentioned. I'd like to see C# and .Net shake off that slight corporate feel and move more into the open source arena but I just can't see that happening. I'd be interested to hear peoples opinion on why this might be?

• Optimizing Your Sales Page the Right Way

  In this article, I will explain how it is sometimes more important to write a page with the people in mind, how they think, feel and react than to have it optimized for the mere purpose of drawing traffic. Having sales pages in your online business or website is the main moneymaker for your business. So it is important to have the copy on that page to be as congruent to the language of the people you are selling to.
