  • Clean Code: A Handbook of Agile Software Craftsmanship – book review

    - by DigiMortal
       Writing code that is easy read and test is not something that is easy to achieve. Unfortunately there are still way too much programming students who write awful spaghetti after graduating. But there is one really good book that helps you raise your code to new level – your code will be also communication tool for you and your fellow programmers. “Clean Code: A Handbook of Agile Software Craftsmanship” by Robert C. Martin is excellent book that helps you start writing the easily readable code. Of course, you are the one who has to learn and practice but using this book you have very good guide that keeps you going to right direction. You can start writing better code while you read this book and you can do it right in your current projects – you don’t have to create new guestbook or some other simple application to start practicing. Take the project you are working on and start making it better! My special thanks to Robert C. Martin I want to say my special thanks to Robert C. Martin for this book. There are many books that teach you different stuff and usually you have markable learning curve to go before you start getting results. There are many books that show you the direction to go and then leave you alone figuring out how to achieve all that stuff you just read about. Clean Code gives you a lot more – the mental tools to use so you can go your way to clean code being sure you will be soon there. I am reading books as much as I have time for it. Clean Code is top-level book for developers who have to write working code. Before anything else take Clean Code and read it. You will never regret your decision. I promise. Fragment of editorial review “Even bad code can function. But if code isn’t clean, it can bring a development organization to its knees. Every year, countless hours and significant resources are lost because of poorly written code. But it doesn’t have to be that way. What kind of work will you be doing? You’ll be reading code—lots of code. And you will be challenged to think about what’s right about that code, and what’s wrong with it. More importantly, you will be challenged to reassess your professional values and your commitment to your craft. Readers will come away from this book understanding How to tell the difference between good and bad code How to write good code and how to transform bad code into good code How to create good names, good functions, good objects, and good classes How to format code for maximum readability How to implement complete error handling without obscuring code logic How to unit test and practice test-driven development This book is a must for any developer, software engineer, project manager, team lead, or systems analyst with an interest in producing better code.” Table of contents Clean code Meaningful names Functions Comments Formatting Objects and data structures Error handling Boundaries Unit tests Classes Systems Emergence Concurrency Successive refinement JUnit internals Refactoring SerialDate Smells and heuristics A Concurrency II org.jfree.date.SerialDate Cross references of heuristics Epilogue Index

  • Simple blogging software (WP replacement)

    - by jontes
    I'm sorry if this is not the right place to ask this question, but I think it's certainly better than at stackoverflow.com. I'm planning to redesign my website and looking for a WordPress replacement for my blog. My requirements are: simple (I won't do a large, complicated website) and lucid well coded (OOP), extensions, templates, active development (not 3 years old) nice but temperate text editor (+images, links), tags and categories, page break easy integration with Flickr, Picasa and social networks technology: PHP and MySQL, not cloud service (like Posterous or Tumblr) Could you recommend me some blogging software which would meet these criteria?

  • 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?

  • Software rendering 3d triangles in the proper order

    - by at.
    I'm implementing a basic 3d rendering engine in software (for education purposes, please don't mention to use an API). When I project a triangle from 3d to 2d coordinates, I draw the triangle. However, it's in a random order and so whatever gets drawn last draws on top of all other triangles (which might be in front of triangles it shouldn't be in front of)... Intuitively, seems I need to draw the triangles in the correct order. So I can calculate all their distances to the camera and sort by that. The objects furthest away get drawn last. Is this the proper way to render triangles? If I'm sorting all the objects, this is n*log(n) now. Is this the most efficient way to do this?

  • Which software development methodologies can be seen as foundations

    - by Bas
    I'm writing a small research paper which involves software development methodologiess. I was looking into all the available methodology's and I was wondering, from all methodologies, are there any that have provided the foundations for the others? For an example, looking at the following methodologies: Agile, Prototyping, Cleanroom, Iterative, RAD, RUP, Spiral, Waterfall, XP, Lean, Scrum, V-Model, TDD. Can we say that: Prototyping, Iterative, Spiral and Waterfall are the "foundation" for the others? Or is there no such thing as "foundations" and does each methodology has it's own unique history? I would ofcourse like to describe all the methodology's in my research paper, but I simply don't have the time to do so and that is why I would like to know which methodologies can be seen as representatives.

  • The Basics of Project Management / Software Development

    - by Sam
    It suddenly struck me today that I have never developed any large application or worked with a team of programmers, and so am missing out a lot - both in terms of technical knowledge and the social-fun part of it. And I would like to rectify that - an idea is to start an open source group by training college students (for no charge) and developing some open source application with them. Please give me some basic advice on the whole process of how to (1) plan and (2) manage projects in a team. What new skill sets would you recommend? (I have read joel on software and 37 Signals, and got many insightful tips from them. But I'd like a little more technical knowledge ...) Background (freelancer, past 4+ years) - Computer engineer graphic / web designer online marketing moved on to programming in PHP, Perl, Python did Oracle DBA OCP training to understand DB's current self-assigned title - web application developer.

  • Buzzword for "performance-aware" software development

    - by errantlinguist
    There seems to be an overabundance of buzzwords for software development styles and methodologies: Agile development, extreme programming, test-driven development, etc... well, is there any sort of buzzword for "performance-aware" development? By "performance awareness", I don't necessarily mean low-latency or low-level programming, although the former would logically fall under the blanket term I'm looking for. I mean development in which resources are recognised to be finite and so there is a general emphasis on low computational complexity, good resource management, etc. If I was to be snarky, I would say "good programming", but that doesn't seem to get the message across so well...

  • Ubuntu Software Center: Add option to launch application after installation

    - by RomanIvanov
    Does any body know why Ubuntu Software Center can not launch applications after installation ? All user install application only for one purpose - launch it and use. Why we need to install it and after that search it in number of menus. Even Packages are mixed with applications that why not just allow to launch only applications that put smth in menu. Example of such convenient application center - android market, ... . Ubuntu 11.10 have pretty/sexy center but .... vital function still missed.

  • Download mirrors down after fresh installation

    - by user169866
    I dont know whats the problem but it seems after every fresh installation of ubuntu in any device (have started noticing this problem since ubuntu 11.04) the connection to the software sources are down. I cannot download any software from either apt-get or software center. Also i cannot use the Universal Source for packages like chromium, etc. And then suddenly after a few days, the mirrors are back up again!! Its normal back again! I dont know what the problem is, but it happens every time. Is there any solution to this or we just have to wait for a few days till the mirrors are back again? (and I have also tried changing the download server, It doesn't helps!)

  • Packages don't show up after adding ppa

    - by user32993
    I added ppa:ubuntu-mozilla-daily/ppa/firefox-aurora/ubuntu oneiric and ppa:banshee-team/ppa/ubuntu oneiric to my software sources, then did apt-get update. However, after selecting their specific sources from the menu in Software Center, the only packages available are language packs and extensions for Banshee and firefox-aurora. I had already uninstalled Banshee and Firefox. If I try and install Banshee/Aurora with sudo apt-get it will install the old version. Searching for Banshee/Aurora in Software Center only shows the old version. I'm guessing the packages in the PPAs conflict with the packages in the main sources. How do I install the newer versions?

  • Why are software schedules so hard to define?

    - by 0A0D
    It seems that, in my experience, getting us engineers to accurately estimate and determine tasks to be completed is like pulling teeth. Rather than just giving a swag estimate of 2-3 weeks or 3-6 months... what is the simplest way to define software schedules so they are not so painful to define? For instance, customer A wants a feature by 02/01/2011. How do you schedule time to implement this feature knowing that other bug fixes may be needed along the way and take up additional engineering time?

  • Your software-problem-solution approach

    - by Panoy
    I am unfamiliar with many software development philosophies/approaches such as these: DDD - Domain Driven Development Design TDD - Test Driven Development BDD - Behavior Driven Development Other 3-letter acronym that ends with "development" and many more My question is, when will you get to decide to choose what kind of philosophy/approach to follow? Especially the top 3 approach in the list: What is TDD for? Why use DDD for this problem? Mainly your answer would be a case-to-case basis or maybe that there is no single universal philosophy/approach to consider. In that case, could you just tell me what type of project/scenario and why did you use that philosophy/approach.

  • Examples of "Lost art" on software technology/development

    - by mamcx
    With the advent of a new technology, some old ideas - despite been good - are forgotten in the process. I read a lot how some "new" thing was already present in Lisp like 60 years ago, but only recently resurface with other name or on top of another language. Now look like the new old thing is build functional, non-mutable, non-locking-thread stuff... and that make me wonder what have been "lost" in the art of development of software? What ideas are almost forgotten, waiting for resurface? One of my, I remember when I code in foxpro. The idea of have a full stack to develop database apps without impedance mismatch is something I truly miss. In the current languages, I never find another environment that match how easy was develop in fox back them. What else is missing?

  • Software development, basics of design, conventions and scalability

    - by goce ribeski
    I need to improve my programming skills in order to achieve better scalability for the software I'm working on. Purpose is to learn the rules of adding new modules and features, so when it comes to maintaining existing ones there is some concept. So, I'm looking for a good book, tutorial or websites where I can continue to read about this. Currently, what I know and what I do is: to design relational database(3NF), make separate class for each table put that in MVC implement modular programming ...write code and hope for the best... I presume that next things I need to learn more deeply are: programming codex(naming, commenting, conventions...), organize functions building interfaces organizing custom made libraries, organizing API that I'm using, documenting, team work... ... At last what my job is, it does't need to affect your answer, PHP CodeIgniter developer.

  • Ubuntu software center crashes when i try to download anything

    - by vaggelas
    I was trying to set up an old printer by installing several drivers, and I got a problem in software center. I am unable to download anything from it. It opens, but when I try to download something it drops an error message and the installation stops. I can do all the installations from command line, so it is not a major problem, but still will be nice having it again. I reinstall it several times from terminal trying all the solutions I found in the forum, but still the problem is here. Any help is appreciated. This is the error I get. traceback usr/share/softwarecenter/backend/installbackend_impl/aptd.py line 383 in install defer = true DbusException : org.freedesktop.Dbus.Error.Spawn.Execfailed: failed to execute program /usr/lib/dbus-1.0/dbus-daemon-launch-helper = Success

  • Best practices for upgrading user data when updating versions of software

    - by Javy
    In my code I check the current version of the software on launch and compare it to the version stored in the user's data file(s). If the version is newer, then I call different methods to update the old data to the newer data version, if necessary. I usually have to make a new method to convert the data with each update that changes user data in some way, and cannot remove the old ones in case there was someone who missed an update. So the app must be able to go through each method call and update their data until they get their data current. With larger data sets, this could be a problem. In addition, I recently had a brief discussion with another StackOverflow user this and he indicated he always appended a date stamp to the filename to manage data versions, although his reasoning as to why this was better than storing the version data in the file itself was unclear. Since I've rarely seen management of user data versions in books I've read, I'm curious what are the best practices for naming user data files and procedures for updating older data to newer versions.

  • Software Center doesn't ask for a password anymore

    - by Jeff
    So, out of the blue, software-center stopped asking me for a password. It just runs, and then turns grey. Works fine as root, or with sudo. While investigating, I found out about polkit (new to me), and looked at the policies, which seem fine. Looking under localauthority, however, showed that while the sub-directories (10-, 20-, 30-, 50-, 90-) are there, there aren't any files under those. Is that my problem? Should there be a file in the 50-local.d? Or am I still looking in the wrong place for my problem? I looked for similar questions and looked at the answers, but they don't really help any. One other thing, I'm not sure it's related but seemed to happen about the same time: The Dash Home only shows items for recent files and downloads. Nothing anywhere else anymore.

  • Install software with 12.04

    - by tigris
    Just freshly installed from 12.04 after using 11.04 and dist-upgrading to 11.10 a few months back, figured a fresh installation was due. First thing I noticed is that synaptic is no longer installed by default. I've no issues with this, and assume the approach to install packages is now via the ubuntu software center. However, I notice there are a lot of packages missing. I was looking for "vagrant", which I've had to install manually with a sudo apt-get install, but was hoping to use GUI for most things. Surely there is a GUI way? I also noticed when checking for "vim", it comes up with gVim and a little note at the bottom saying "show 2 technical items", which when clicked shows the vim I was looking for. Just curious what the expected GUI way is of installing these supposed "technical packages".
