  • What defines code readability?

    - by zxcdw
    It is often said that readability is perhaps the most important quality-defining measure of a given piece of code for reasons concerning maintainability, ease of understanding and use. What defines the word readable in context of program source code? What kind of definitive aspects are there to code readability? I would be grateful with code examples of readable code, along with reasoning why it is readable.

  • Web application Project management methodologie

    - by dutchiexl
    I am looking to streamline my company's web development process. Including analysis. I myself am specialized in XP and Scrum. But we are building web application with a process cycle of 3-4 weeks and a lifetime of 1-4 months. When a project is sold, only then the project managers (= people who do analysis but know nothing about it = a small flow chart and some screen shots as analysis) What is happening is: A LOT of change requests Minimal development time Minimal analysis time NOW: the main question :) can you recommend me some methodologies and books to read for the entire project management ? Thanks in advance @Edit, I myself was looking at a combination of SCRUM for the management with flowcharts, + RAD/LD for development, and trying to distilate something from that.

  • how do you manage application performance reviews

    - by CoolBeans
    I have been trying to figure out ways to effectively do performance reviews before an install happens for all releases done by our team. Do you usually make this a part of code review process or do you handle it as a separate review task? FYI - we do not have a dedicated performance testing team. It is up to the developers to make sure the app performs well. The apps I am referring to are web applications.

  • What happens differently when you add a task Asynchronously on GAE?

    - by Ben Grunfeld
    Google's doc on async tasks assumes knowledge of the difference between regular and asynchronously added tasks. add_async(task, transactional=False, rpc=None) Asynchronously add a Task or a list of Tasks to this Queue. How is adding tasks asynchronously different to adding them regularly. I.e. what is the difference between using add(task, transactional=False) and add_async(task, transactional=False, rpc=None) I've heard that adding tasks regularly blocks certain things. Any explanation of what it blocks and how, and how async tasks don't block would be greatly appreciated.

  • Git Project Dependencies on GitHub

    - by VirtuosiMedia
    I've written a PHP framework and a CMS on top of the framework. The CMS is dependent on the framework, but the framework exists as a self-contained folder within the CMS files. I'd like to maintain them as separate projects on GitHub, but I don't want to have the mess of updating the CMS project every time I update the framework. Ideally, I'd like to have the CMS somehow pull the framework files for inclusion into a predefined sub-directory rather than physically committing those files. Is this possible with Git/GitHub? If so, what do I need to know to make it work? Keep in mind that I'm at a very, very basic level of experience with Git - I can make repositories and commit using the Git plugin for Eclipse, connect to GitHub, and that's about it. I'm currently working solo on the projects, so I haven't had to learn much more about Git so far, but I'd like to open it up to others in the future and I want to make sure I have it right. Also, what should my ideal workflow be for projects with dependencies? Any tips on that subject would also greatly appreciated. If you need more info on my setup, just ask in the comments.

  • How can I create a square 10x10 grid using nested for loops in Java? [migrated]

    - by help
    I'm trying to create a 10x10 grid using for loops in Java. I'm able to create rows going up and down but not repeating. for(int i = 1; i < temperatures.length; i++) { temperatures[i] = (temperatures[i-1] + 12) / 2; //takes average of 12 and previous temp } } public void paint(Graphics g) { for(int y = 1; y < 9; y++) { g.setColor(Color.black); g.drawRect(10, 10, 10, 10); g.drawRect(10, 10, 10, 20); g.drawRect(10, 10, 10, 30); g.drawRect(10, 10, 10, 40); g.drawRect(10, 10, 10, 50); g.drawRect(10, 10, 10, 60); g.drawRect(10, 10, 10, 70); g.drawRect(10, 10, 10, 80); g.drawRect(10, 10, 10, 90); g.drawRect(10, 10, 10, 100); for(int x = 1; x < 9; x++) { g.setColor(Color.black); g.drawRect(10, 10, 10, 10); g.drawRect(10, 10, 20, 10); g.drawRect(10, 10, 30, 10); g.drawRect(10, 10, 40, 10); g.drawRect(10, 10, 50, 10); g.drawRect(10, 10, 60, 10); g.drawRect(10, 10, 70, 10); g.drawRect(10, 10, 80, 10); g.drawRect(10, 10, 90, 10); g.drawRect(10, 10, 100, 10); } } } }

  • What is an effective git process for managing our central code library?

    - by Mathew Byrne
    Quick background: we're a small web agency (3-6 developers at any one time) developing small to medium sized Symfony 1.4 sites. We've used git for a year now, but most of our developers have preferred Subversion and aren't used to a distributed model. For the past 6 months we've put a lot of development time into a central Symfony plugin that powers our custom CMS. This plugin includes a number of features, helpers, base classes etc. that we use to build custom functionality. This plugin is stored in git, but branches wildly as the plugin is used in various products and is pulled from/pushed to constantly. The repository is usually used as a submodule within a major project. The problems we're starting to see now are a large number of Merge conflicts and backwards incompatible changes brought into the repository by developers adding custom functionality in the context of their own project. I've read Vincent Driessen's excellent git branching model and successfully used it for projects in the past, but it doesn't seem to quite apply well to our particular situation; we have a number of projects concurrently using the same core plugin while developing new features for it. What we need is a strategy that provides the following: A methodology for developing major features within the code repository. A way of migrating those features into other projects. A way of versioning the core repository, and of tracking which version each major project uses. A plan for migrating bug fixes back to older versions. A cleaner history that's easier to see where changes have come from. Any suggestions or discussion would be greatly appreciated.

  • Which algorithms/data structures should I "recognize" and know by name?

    - by Earlz
    I'd like to consider myself a fairly experienced programmer. I've been programming for over 5 years now. My weak point though is terminology. I'm self-taught, so while I know how to program, I don't know some of the more formal aspects of computer science. So, what are practical algorithms/data structures that I could recognize and know by name? Note, I'm not asking for a book recommendation about implementing algorithms. I don't care about implementing them, I just want to be able to recognize when an algorithm/data structure would be a good solution to a problem. I'm asking more for a list of algorithms/data structures that I should "recognize". For instance, I know the solution to a problem like this: You manage a set of lockers labeled 0-999. People come to you to rent the locker and then come back to return the locker key. How would you build a piece of software to manage knowing which lockers are free and which are in used? The solution, would be a queue or stack. What I'm looking for are things like "in what situation should a B-Tree be used -- What search algorithm should be used here" etc. And maybe a quick introduction of how the more complex(but commonly used) data structures/algorithms work. I tried looking at Wikipedia's list of data structures and algorithms but I think that's a bit overkill. So I'm looking more for what are the essential things I should recognize?

  • Programming in the United States Airforce - How hard to get a job doing it? [closed]

    - by Holland
    I already know how to program. Been at it for a year; the language I've worked mostly with has been C++, and I'm currently studying x86 assembly programming, with the goal to move towards ARM assembly after I've finished with that. Thus, given my experience and knowledge, I'm curious to know if any "vets" around here have had any excursions in the military doing software/electrical engineering, and how hard it would be to actually get a job doing it - with someone who already has previous experience and knowledge regarding that field, however slight. By definition of "hard", in this context, I suppose I'd be referring to the required knowledge to actually be a "shoe-in" for both low level and high level software/hardware applications. I know hex fairly well, and enough to convert that hex to binary. I also have an ok knowledge of algorithms, such as Binary Search Tree, Linked List, etc. Everything I've learned so far has been self taught for the most part.

  • Does heavy library and snippet codes usage make you a bad programmer?

    - by Henrik P.
    Overall I'm in programming for about 8 years now and it seems to me that I'm relying more and more on open source libraries and snippets (damn you GitHub!) to "get the job done". I know that in time I could write me own implementation but I like to focus on the overall design. Is this normal (non cooperate environment)? Does it make you a bad programmer if "programming" is nothing more than cluing different libraries together. Feels like it. I know about "don't reinvent the wheel" but what happens when you don't invent a single wheel anymore. What's your take on this?

  • Why do you hate Java? Is it the language or the framework? [closed]

    - by zneak
    According to you all, Java is the third most-hated language here. The two other most hated languages are PHP and VBScript. (It's quite funny how they stand together on the podium.) I'd like to make it known that the question mostly addresses people who don't like Java. I assume here a number of subjective opinions as facts because they're usually considered true among people who don't like Java, and I don't want to be convinced otherwise here. If you're a Java enthusiast, you might find this question frustrating. It's never been made clear if people hate Java itself, or if they hate it because of the framework, or if it's a mixture of the two. On a side you have the language, where you have: the "everything should be an object" philosophy, even in instances where it should obviously be something else (event handlers I'm pointing you); checked exceptions; the idea that all logic should be presented as methods and properties is a big no-no; the fact that "closures" created by anonymous types only include final variables and arguments, but will allow write access to any member of the parent class; a few more. On the other side, you have the JDK, with... its load of inconsistencies and overengineering; monolithic class hierarchies; meaningless base exceptions like IOException (though other frameworks have similar exception hierarchies); sluggish responsiveness even with Swing; a few more. My question is, do you think that, if either one (Java or the JDK) was taken alone, and the other was dropped in favor of something else, the new combination would be better? For instance, if you could use the C# syntax with the JDK (adapting get*/set* methods into properties, and interfaces with only one method into delegates), or the Java syntax with the .NET Framework (doing the inverse transformations), would things get better in your opinion?

  • Compute if a function is pure

    - by Oni
    As per Wikipedia: In computer programming, a function may be described as pure if both these statements about the function hold: The function always evaluates the same result value given the same argument value(s). The function result value cannot depend on any hidden information or state that may change as program execution proceeds or between different executions of the program, nor can it depend on any external input from I/O devices. Evaluation of the result does not cause any semantically observable side effect or output, such as mutation of mutable objects or output to I/O devices. I am wondering if it is possible to write a function that compute if a function is pure or not. Example code in Javascript: function sum(a,b) { return a+b; } function say(x){ console.log(x); } isPure(sum) // True isPure(say) // False

  • Resources for improving your comprehension of recursion?

    - by Andrew M
    I know what recursion is (when a patten reoccurs within itself, typically a function that calls itself on one of its lines, after a breakout conditional... right?), and I can understand recursive functions if I study them closely. My problem is, when I see new examples, I'm always initially confused. If I see a loop, or a mapping, zipping, nesting, polymorphic calling, and so on, I know what's going just by looking at it. When I see recursive code, my thought process is usually 'wtf is this?' followed by 'oh it's recursive' followed by 'I guess it must work, if they say it does.' So do you have any tips/plans/resources for building up your skills in this area? Recursion is kind of a wierd concept so I'm thinking the way to tackle it may be equally wierd and inobvious.

  • Weaknesses of 3-Strike Security

    - by prelic
    I've been reading some literature on security, specifically password security/encryption, and there's been one thing that I've been wondering: is the 3-strike rule a perfect solution to password security? That is, if the number of password attempts is limited to some small number, after which all authentication requests will not be honored, will that not protect users from intrusion? I realize gaining access or control over something doesn't always mean going through the authentication system, but doesn't this feature make dictionary/brute-force attacks obsolete? Is there something I'm missing?

  • What type of career path / jobs for a developer to have best work life balance?

    - by programmx10
    I know some people may look down on a question like this but I've been thinking lately a lot about what direction I can take my career to have a good work life balance, since I have been working for a startup where hours tend to drag on, etc and I find it often drains the life out of me. I have been going to interviews and some other companies are also startups / new companies and seem to have a similar attitude about working long hours. Maybe its the technologies I use, the type of development, I don't know but I'm curious if anyone can offer advice on what a path is to be a programmer / developer but work for a company that respects a regular work week and would only rarely find the need to move past this. I realize this won't lead to being the highest paid in my field but I'm ok with that and feel the tradeoff would be worth it as it would also give me time for my own projects, etc. I know some people may say this is too general but I believe it is a programmer specific question because I believe there tends to be a higher than average rate of working overtime, etc and people working in "startup" venture situations than in many other fields and there is definitely a mindset among a lot of people in the field of working long hours that doesn't exist in every industry.

  • C++ Library API Design

    - by johannes
    I'm looking for a good resource for learning about good API design for C++ libraries, looking at shared objects/dlls etc. There are many resources on writing nice APIs, nice classes, templates and so on at source level, but barely anything about putting things together in shared libs and executables. Books like Large-Scale C++ Software Design by John Lakos are interesting but massively outdated. What I'm looking for is advice i.e. on handling templates. With templates in my API I often end up with library code in my executable (or other library) so if I fix a bug in there I can't simply roll out the new library but have to recompile and redistribute all clients of that code. (and yes, I know some solutions like trying to instantiate at least the most common versions inside the library etc.) I'm also looking for other caveats and things to mind for keeping binary compatibility while working on C++ libraries. Is there a good website or book on such things?

  • What do you do when you realize your job requires you to do something out of your depth?

    - by Billy ONeal
    For a large software project recently, I was really out of my depth. And I did actually know this; and that the only reason I was employed was mostly a lack of other qualified candidates. The job was to build a large application on top of PHP/MySQL, a system I had little experience with. (I did advise the employer of this beforehand -- I've been spoiled by C# ASP.NET/MVC and MSSQL Server) The main reason I applied was location, location, location -- on campus jobs which actually have any programming component are relatively rare. For almost a year and a half I've slogged through this, and I think I can say I know (at least somewhat) what I'm doing now. I've made some mistakes, torn out some hair, and moved on. (I'm still working on this system nowadays, but I no longer feel completely lost) In the future though, I'd like to keep my personal and professional self a little healthier than what occurred in this case. So I'm curious -- what's the best way to handle a situation like this?

  • How to write a very basic compiler [closed]

    - by Ali
    Possible Duplicate: Best Online resources to learn about Compilers? What would be the best way to learn about compilers, and executable formats? Advanced compilers like gcc compile codes into machine readable files according to the language in which the code has been written (e.g. C, C++, etc). In fact, they interpret the meaning of each codes according to library and functions of the corresponding languages. Correct me if I'm wrong. I wish to better understand compilers by writing a very basic compiler (probably in C) to compile a static file (e.g. Hello World in a text file). I tried some tutorials and books, but all of them are for practical cases. They deal with compiling dynamic codes with meanings connected with the corresponding language. How can I write a basic compiler to convert a static text into a machine readable file? The next step will be introducing variables into the compiler; imagine that we want to write a compiler which compile only some functions of a language. Introducing practical tutorials and resources is highly appreciated :-)

  • Should companies require developers to credit code they didn't write?

    - by sunpech
    In academia, it's considered cheating if a student copies code/work from someone/somewhere else without giving credit, and tries to pass it off as his/her own. Should companies make it a requirement for developers to properly credit all non-trivial code and work that they did not produce themselves? Is it useful to do so, or is it simply overkill? I understand there are various free licenses out there, but if I find stuff I like and actually use, I really feel compelled to give credit via comment in code even if it's not required by the license (or lack thereof one).

  • How was Git designed?

    - by Mark Canlas
    My workplace recently switched to Git and I've been loving (and hating!) it. I really do love it, and it is extremely powerful. The only part I hate is that sometimes it's too powerful (and maybe a bit terse/confusing). My question is... How was Git designed? Just using it for a short amount of time, you get the feel that it can handle many obscure workflows that other version control systems could not. But it also feels elegant underneath. And fast! This is no doubt in part to Linus's talent. But I'm wondering, was the overall design of git based off of something? I've read about BitKeeper but the accounts are scant on technical details. The compression, the graphs, getting rid of revision numbers, emphasizing branching, stashing, remotes... Where did it all come from? Linus really knocked this one out of the park and on pretty much the first try! It's quite good to use once you're past the learning curve.

  • Can I re-license Academic Free License code under 2-Clause BSD / ITC?

    - by Stefano Palazzo
    I want to fork a piece of code licensed under the Academic Free License. For the project, it would be preferable to re-license it under the ISC License or the 2-Clause BSD license, which are equivalent. I understand that the AFL grants me things such as limitation of liability, but licensing consistency is much more important to the project, especially since we're talking about just 800 lines of code, a quarter of which I've modified in some way. And it's very important for me to give these changes back to the community, given the fact that this is software relevant to security - I need the public scrutiny that I'll get by creating a public fork. In short: At the top of the file I want to say this, or something like it: # Licensed under the Academic Free License, version 3 # Copyright (C) 2009 Original Author # Licensed under the ISC License # Copyright (C) 2012 Stefano Palazzo # Copyright (C) 2012 Company Am I allowed to do this? My research so far indicates that it's not clear whether the AFL is GPL-Compatible, and I can't really understand any of the stuff concerning re-licensing to other permissive licenses. As a stop gap, I would also be okay with re-licensing under the GPL, however: I can find no consensus (though I can find disagreement) on whether this is allowed at all, and I don't want to risk it, of course.

  • Which web framework to use under Backbonejs?

    - by egidra
    For a previous project, I was using Backbonejs alongside Django, but I found out that I didn't use many features from Django. So, I am looking for a lighter framework to use underneath a Backbonejs web app. I never used Django built in templates. When I did, it was to set up the initial index page, but that's all. I did use the user management system that Django provided. I used the models.py, but never views.py. I used urls.py to set up which template the user would hit upon visiting the site. I noticed that the two features that I used most from Django was South and Tastypie, and they aren't even included with Django. Particularly, django-tastypie made it easy for me to link up my frontend models to my backend models. It made it easy to JSONify my front end models and send them to Tastypie. Although, I found myself overriding a lot of tastypie's methods for GET, PUT, POST requests, so it became useless. South made it easy to migrate new changes to the database. Although, I had so much trouble with South. Is there a framework with an easier way of handling database modifications than using South? When using South with multiple people, we had the worse time keeping our databases synced. When someone added a new table and pushed their migration to git, the other two people would spend days trying to use South's automatic migration, but it never worked. I liked how Rails had a manual way of migrating databases. Even though I used Tastypie and South a lot, I found myself not actually liking them because I ended up overriding most Tastypie methods for each Resource, and I also had the worst trouble migrating new tables and columns with South. So, I would like a framework that makes that process easier. Part of my problem was that they are too "magical". Which framework should I use? Nodejs or a lighter Python framework? Which works best with my above criteria?

  • Purchasing Visual Studio 2010 Ultimate and Professional version

    - by Don
    We are a small team with 5-7 developers. We are planning to purchase Visual Studio 2010, better with one or two Ultimate version, others with professional version. The suggestion from Microsoft is getting it from retail. We find we can get them from http://msdn.microsoft.com/en-us/subscriptions/buy.aspx or http://www.amazon.com/Visual-Studio-2010-Ultimate-MSDN/dp/B0038KNER0/ref=sr_1_fkmr3_2?ie=UTF8&qid=1296675635&sr=8-2-fkmr3. From Amazon, it will be lower cost. We wonder if we buy from Microsft directly we can get additional benefits like supports, which other retailers can not provide. Anyone has any ideas? What is the cost effient way? Thanks,

  • The road to become a programmer [closed]

    - by user68991
    I'm looking for a 'career' change, I don't actually have a career at the moment since I haven't been able to find a job since I graduated with a degree in Materials Engineering. One of my loves has always been computers and programming, though I have never studied it seriously. When I was 11 I wrote a very basic graphical 'game' using notepad and HTML, where I drew each possible position of the main character on the different 'maze' level in MSPaint, using pictures of arrows as links to a new page with the character in a new position, and various other buttons would pop up 'search box', 'press button' etc. At the time I thought this was an amazing achievement of my programming skills. I've used a little bit of FORTRAN 90 whilst I was at university, which rekindled my interest in programming. When I was a kid I mainly used C and HTML, but only very basically as my 'game' suggests. I want to learn a new programming language, I'm not entirely sure where I want to go with it, but the number one contender at the moment is android apps. I'm looking at learning Java, but I've read that it's a difficult place to begin with; so I've also looked at learning Visual Basic, which I believe is also object oriented(?) but a little easier to understand? (not that I know what an object is anyway). Any information people could give me regarding which language to learn, and if there are any good online tutorial for that language I'd really appreciate it. Some of the tutorials I've used so far are full or jargon I can't understand. Also, I'm not afraid of maths having got an engineering degree. Thanks in advance for any help/advice. James
