  • Language Design: Are languages like phyton and coffescript really more comprehendable?

    - by kittensatplay
    the "Verbally Readable !== Quicker Comprehension" arguement on http://ryanflorence.com/2011/case-against-coffeescript/ is really potent and interesting. i and im sure other would be very interested in evidence arguing against this. there's clear evidence for this and i believe it. ppl naturally think in images, not words, so we should be designing languages dissimilar to human language like english, french, whatever. being "readable" is quicker comprehension. most articles on wikipedia are not readable as they are long, boring, dry, sluggish, very very wordy, and because wikipedia documents a ton of info, is not especially helpful when compared to much more helpful sites with more practical, useful, and relevant info. but languages like phyton and coffescript are "verbally readable" in that they are closer to the english language syntax, and programming firstly and mainly in python, im not so sure this is really a good thing. the second interesting argument is that coffeescript is an intermediator so thereby another step between to ends, which may increase chances of bugs. while coffeescript has other practical benefits, this question is focused specifically on evidence showing support for the counter-case of language "readability"

  • Is possible to write too many asserts?

    - by Lex Fridman
    I am a big fan of writing assert checks in C++ code as a way to catch cases during development that cannot possibly happen but do happen because of logic bugs in my program. This is a good practice in general. However, I've noticed that some functions I write (which are part of a complex class) have 5+ asserts which feels like it could potentially be a bad programming practice, in terms of readability and maintainability. I think it's still great, as each one requires me to think about pre- and post-conditions of functions and they really do help catch bugs. However, I just wanted to put this out there to ask if there is a better paradigms for catching logic errors in cases when a large number of checks is necessary.

  • Is excessive indirection and/or redundant encapsulation a recognized concept?

    - by Omega
    I'm curious if there's a series of tendencies or anti-patterns when programming whereby a developer will always locally re-wrap external dependencies when consuming them. A slightly less vague example might be say when consuming an implementation of an interface or abstract, and mapping every touch-point locally before interacting with them. Like an overcomplicated take on composition. Given my example, would the interface not be reliable enough and any change to it never be surmountable any any level of indirection? Is this a good or a bad practice? Can it ever go too far? Does it have a proper name?

  • What undergraduate course to choose for a mature programmer returning to study

    - by Dve
    I have been developing applications (mostly web-based) for almost 10 years now and have learnt pretty much everything I know through experience (and the internet!). I wouldn't call myself an advanced programmer, but I am quite proficient in several languages (C#, Javascript, Ruby, HTML/CSS etc) and spend a quite a bit of time working on personal projects and reading countless books & articles. I am looking to emigrate to Canada, hopefully Vancouver (im from the UK) and one way would be on a student visa, if I was going to be studying for a minimum of 2 years. Having never been to university or achieved anything higher than A-Levels I am quite tempted by this path. The thought of learning is more exciting to me now than it was 10 years ago! What would be people recommend as a good undergraduate course to take that would complement this career path? Would Math be beneficial, if so which area of Math? TL;DR What undergraduate course/area of study would complement 10 years of (mostly web-based) programming experience?

  • Using High Level Abstractions

    - by Jonn
    I'm not sure if I'm using the correct term, but would you program using High-level abstractions like Powerbuilder, or some CMS like MODx or DotNetNuke? I haven't dabbled in any of these yet. The reason I'm asking is that I kind of feel intimidated by the whole notion of using any abstraction over the languages I'm using. I'm thinking that my job might be over-simplified. While it may provide business solutions faster, I'd rather be coding straight from, in my case, .NET. Do/Would you use abstractions like these or prefer them over programming in lower level languages?

  • take my Java skills to the next level

    - by waingram
    I am well versed in the basics of Java programming, although through most of my career I have been maintaining, upgrading, and debugging someone else's Java code. I am mainly familiar with basic servlet applications. I have a strong beginner knowledge of Maven and Ant. I have more web development with Ruby on Rails, but would like to bring my Java skills up to par with regard to web development. It seems the world of Java is so big, I have no idea what the next logical step is for me. Spring? JAX-RB? EJBs? What is the next logical step for someone like me and how would you recommend I approach it?

  • Question about SEO and Domains

    - by jasondavis
    This is my first post on here as I am mainly on Stackoverflow and Serverfault. I have been programming for at least 10 years now, have made hundreds of websites but I have just recently started getting into Design and the SEO side of sites, sad that I have been overlooking these for so many years. I have pretty good knowledge from all my years of SEO but I have never really looked into it until now. My question, I would like to build a site that targets many different key words for the search engines, for an example. Let's say I built a site about Outdoor activities called outdoorreview.com and I planned on having many sections hunting fishing Hiking camping cycling climbing etc... For best Search Engine results, how could I get the most search engine traffic to all these ares? Also how should I structure the way to get to them, outdoorreview.com/Hiking/ or hiking.outdoorreview.com ?

  • In PHP, what are the different design patterns to implement OO controllers as opposed to procedural controllers?

    - by Ryan
    For example, it's very straightforward to have an index.php controller be a procedural script like so: <?php //include classes and functions //get some data from the database //and/or process a form submission //render HTML using your template system ?> Then I can just navigate to http://mysite.com/index.php and the above procedural script is essentially acting as a simple controller. Here the controller mechanism is a basic procedural script. How then do you make controllers classes instead of procedural scripts? Must the controller class always be tied to the routing mechanism?

  • Is there a future for AAA game development in C#? [closed]

    - by kasperov
    When XNA was released in 2006, I was happy and started doing indie attempts. After 3 years or so, there were lots of forum discussions on prospects of AAA game development in C#, and how a high performance vedio game can easily be programmed in C#. Suddenly after 2-3 more years, these discussions have died down and everybody seems like recommending native C++... What programming language should I practice on for long term? Should I stick with C# or do an extra effort for C++? Will AAA game companies adopt C# as a replacement to C++? Note : I aim to work at a AAA game company.

  • How do I make a simple level system?

    - by ROROX
    I've been learning programming for a while and things are slow but steady. I only have a couple experiments that look something like a game (JavaScript,HTML5,CANVAS). One of the things I would like to establish this early in my process though is a basic level system to my games. I'm thinking like Atari, NES type simple. mainMenu , level1 , level2 , ... Later I'll work on including such screens as; titleScreen , pause , highScore. But for now just looking for the basics. Any good articles/tutorial links would help. Or just a snippet of code I can look over. Thank you kindly :)

  • How to study for an Informatics Olympiad [on hold]

    - by Cloud
    One of my goals for next year is to participate in the Australian Informatics Olympiad. As far as I'm aware, it is not too different from Informatics Olympiads in other countries. What would be the best way to study for this? What content should I pay particular attention to while learning in Python? I am currently using the book 'Learn Python the hard way', but are there any other books worthy of a mention? This is the link to their site: http://orac.amt.edu.au/aio/ It contains sample questions, so you can get an idea for the structure or nature of the competition. I know this isn't really a specific programming question, but it would be great if someone could share their experience or give some suggestions for me.

  • What to use to make voice chat (and some more) on a web?

    - by Tunococ
    I am trying to make available on my website a voice chat for a small group of people that allows some other means to interact such as text messaging, photo sharing, file sharing, simple drawing and silly games. In other words, something similar to older MSN Messenger, but on the web. Any ideas on what to use? To clarify, I am looking for suggestions on languages and libraries to use. I want to be able to fully customize it as much as possible because I might want to add other (somewhat interesting) functions later. Low-level programming is fine if required, but platform dependency isn't that much preferred.

  • Looking for a 24 Hour project for multiple languages [closed]

    - by Daan Timmer
    Right two friends and I came up with this idea of having a 24h programming competition. Where we are going to meet at one place and program away for 24hours long. Though we need a 'project'. Something that needs to be made within 24h. Doesn't have to be a real thing, just a nice learning 'thing'. The rules that we setup for ourselves is that the project can be programmed in any language of our own choice. What I know is that one guy is a PHP enthousiastic, we've got a C#/.NET person. And I am quite easy in languages and speak quite a few (PHP/C#.net/C++STL/Python/JavaScript/Java). Anything really language specific is out of the question. Is there anyone who happens to have a great idea for this?

  • atheros wireless ar9285 driver

    - by nikola
    I have been having problems with wireless on Ubuntu 10 and above, Mint 11 and above. The problem is in the driver for the wireless... I can see that there is no driver installed and yet it works but reduced a lot, for example: on windows 7 ultimate 100% on distance of 1 meter (currently running) Mint Cinnamon 15 on same distance 70% when it goes under the 40 % it simply disconnects and than takes a lot of time to connect again I am new to Linux and I don't know anything about programming, yet I love the interface and look of the OS but don't want to reject it for couple of problems. There is, however, a problem with brightness control on laptop, it shows the notification and slider but with no effect The question is: Can somebody explain to me where to download and how to install the ar9285 driver for atheros wireless card laptop acer emachines eme529? or can someone explain this to me only for the LINUX MINT 15 http://www.jrhenkelmann.net/index.php?option=com_content&task=view&id=34 because the synaptic's interface is different than of mint 15 I KNOW this is Ubuntu community but the problems persist in all Linux versions

  • MVC 2 in 2 Minutes!

    - by Steve Michelotti
    In a couple of recent Code Camps, I’ve given my presentation: Top 10 Ways MVC 2 Will Boost Your Productivity. In the presentation, I cover all major new features introduced in MVC 2 with a focus on productivity enhancements. To drive the point home, I conclude with a final demo where I build a couple of screens from scratch highlighting many (but not all) of the features previously covered in the talk. A couple of weeks ago, I was asked to make it available online so here it is. In 2 minutes the demo builds a couple screens from scratch that provide a goal setting tracker for a user. MVC 2 features included in the video are: Template Helpers / Editor Templates Server-side/Client-side Validation Model Metadata for View Model HTML Encoding Syntax Dependency Injection Abstract Controllers Custom T4 Templates Custom MVC Visual Studio 2010 Code Snippets The complete code samples and slide deck can be downloaded here: Top 10 Ways MVC 2 Will Boost Your Productivity.

  • understanding computers [closed]

    - by Ashwin
    Possible Duplicate: Good resources to understand how a program interacts with machine hardware I don't know if this is the correct StackExchange site to ask this question. But I could not find any other. I want to understand how a computer works from the software level to the internal structure. For example what happens when I press a button on keyboard. The OS interprets it and then what changes happen in the flip-flops. How is an operating system written? If it is written using some programming language, then how is that interpreter written. At some point it has to come down to the hardware, right? I know to program in c, c++ and java. But after all these years I am still not sure about what is happening inside. I would be grateful to anyone who points me to to a link or a video that explains this to the deep.

  • How often do CPUs make calculation errors?

    - by veryfoolish
    In Dijkstra's Notes on Structured Programming he talks a lot about the provability of computer programs as abstract entities. As a corollary, he remarks how testing isn't enough. E.g., he points out the fact that it would be impossible to test a multiplication function f(x,y) = x*y for any large values of x and y across the entire ranges of x and y. My question concerns his misc. remarks on "lousy hardware". I know the essay was written in the 1970s when computer hardware was less reliable, but computers still aren't perfect, so they must make calculation mistakes sometimes. Does anybody know how often this happens or if there are any statistics on this?

  • How are design-by-contract and property-based testing (QuickCheck) related?

    - by Todd Owen
    Is their only similarity the fact that they are not xUnit (or more precisely, not based on enumerating specific test cases), or is it deeper than that? Property-based testing (using QuickCheck, ScalaCheck, etc) seem well-suited to a functional programming style where side-effects are avoided. On the other hand, Design by Contract (as implemented in Eiffel) is more suited to OOP languages: you can express post-conditions about the effects of methods, not just their return values. But both of them involve testing assertions that are true in general (rather than assertions that should be true for a specific test case). And both can be tested using randomly generated inputs (with QuickCheck this is the only way, whereas with Eiffel I believe it is an optional feature of the AutoTest tool). Is there an umbrella term to encompass both approaches? Or am I imagining a relationship that doesn't really exist.

  • How to write loosely coupled classes in node.js

    - by lortabac
    I am trying to understand how to design node.js applications, but it seems there is something I can't grasp about asynchronous programming. Let's say my application needs to access a database. In a synchronous environment I would implement a data access class with a read() method, returning an associative array. In node.js, because code is executed asynchronously, this method can't return a value, so, after execution, it will have to "do" something as a side effect. It will then contain at least 1 line of extraneous code which has nothing to do with data access. Multiply this for all methods and all classes and you will very soon have an unmanageable "code soup". What is the proper way to handle this problem? Am I approaching it the wrong way?
