• Why do software engineers hate writing documentation?

  - by Stewart Johnson

  I ask because I quite enjoy it! I'm talking about design documentation and implementation notes (NOT user manuals), which are non-existent in most of the codebases I've been handed. I can understand why a developer wouldn't want to write requirements (that's the analyst's job) or the user documentation (that's a technical writer's job) but I don't get why developers hate writing design docs. I don't think I would feel as if I'd finished the job if I only wrote the code and walked away -- mainly because when I've been introduced to code-only situations I've seen how hard it is to figure out what's been done and what the software does. I would hate for people to suffer the same situation when inheriting my code. What makes you loath writing supporting documentation for your code?

• Why is x86 ugly? aka Why is x86 considered inferior when compared to others?

  - by claws

  Hello, recently I've been reading some SO archives and encountered statements against x86 architecture. http://stackoverflow.com/questions/2667256/why-do-we-need-different-cpu-architecture-for-server-mini-mainframe-mixed-cor says "PC architecture is a mess, any OS developer would tell you that." http://stackoverflow.com/questions/82432/is-learning-assembly-language-worth-the-effort says "Realize that the x86 architecture is horrible at best" http://forums.anandtech.com/showthread.php?t=976577 says "Most colleges teach assembly on something like MIPS because it's much simpler to understand, x86 assembly is really ugly" and many more comments like Compared to most architectures, X86 sucks pretty badly. It's definitely the conventional wisdom that X86 is inferior to MIPS, SPARC, and PowerPC x86 is ugly I tried searching but didn't find any reasons. I don't find x86 bad probably because this is the only architecture I'm familiar with. Can someone kindly give me reasons for considering x86 ugly/bad/inferior compared to others.

• Why dont Android applications provide an "Exit" option?

  - by Howiecamp

  Is there something in the Android developer guidelines that disuadea developers from providing the option to "exit" (stop running) an application from within the application itself? I love multitasking and all but it's not clear to me why: the vast majority of apps don't have their own Exit functions and hence just keep running forever don't give you a choice about running when you turn on the phone - they just do by default Both of these things lead to memory usage constantly increasing and your device running with this performance burden all of the time despite the fact that you may only want certain apps to run some of the time. Am I missing something?

• Django Social Registration - Twitter Callback going to example.com

  - by user578888

  I have been working through installing django social registration on my webfaction account. So far I have the facebook login working. When I attempt to log in to to twitter I get the correct login page but after choosing "Allow" I am forwarded to the following URL: http://example.com/social/twitter/callback/.... where "example.com" is the actual URL it is forwarding to. I have setup the twitter app and have entered a valid oauth callback URL. I have searched the code on my developer machine for references to "example.com" but have not found any. Any help nailing this down will be greatly appreciated.

• Interview - Program on Computer

  - by Gilad Naor

  Spent some time searching, couldn't find exactly what I'm after. We like giving hands-on programming exercises as part of the interview process. The interviewee gets a laptop, with the editor and compiler of his choice. He or she then get a programming exercise and has about an hour to code it. Depending on the nature of the question, internet access is either allowed or forbidden. I'm looking for good general questions for a junior developer. I don't care what language they choose to program in. C++ is as good as Python or Scheme, as long as (s)he can program in it (this rules out "can you write a correct copy-constructor" style questions). I just want to see how they code, if their code is self-documenting, if they write tests, check edge-cases, etc. What kind of questions would you ask?

• Capistrano 3, Rails 4, database configuration does not specify adapter

  - by Kazmin

  When I start cap production deploy it fails like this: DEBUG [4ee8fa7a] Command: cd /home/deploy/myapp/releases/releases/20131025212110 && (RVM_BIN_PATH=~/.rvm/bin RAILS_ENV= ~/.rvm/bin/myapp_rake assets:precompile ) DEBUG [4ee8fa7a] rake aborted! DEBUG [4ee8fa7a] database configuration does not specify adapter You can see that "RAILS_ENV=" is actually empty and I'm wondering why that might be happening? I assume that this is the reason for the latter error that I don't have a database configuration. The deploy.rb file is below: set :application, 'myapp' set :repo_url, '[email protected]:developer/myapp.git' set :branch, :master set :deploy_to, '/home/deploy/myapp/releases' set :scm, :git set :devpath, "/home/deploy/myapp_development" set :user, "deploy" set :use_sudo, false set :default_env, { rvm_bin_path: '~/.rvm/bin' } set :keep_releases, 5 namespace :deploy do desc 'Restart application' task :restart do on roles(:app), in: :sequence, wait: 5 do # Your restart mechanism here, for example: within release_path do execute " bundle exec thin restart -O -C config/thin/production.yml" end end end after :restart, :clear_cache do on roles(:web), in: :groups, limit: 3, wait: 10 do within release_path do end end end after :finishing, 'deploy:cleanup' end?

• Mercurial: What is the benefit of fixing errors in earlier versions

  - by Ken Earley

  According to the guide, under the heading: Fixing errors in earlier revisions, it states this: When you find a bug in some earlier revision you have two options: either you can fix it in the current code, or you can go back in history and fix the code exactly where you did it, which creates a cleaner history. How does going back in history make it cleaner? It still makes a new changeset at tip. Does it have something to do with what is recorded as it's parent? Is there a way to view the logs seeing the newly inserted changeset in that order? This lesson is under the main heading of Lone developer with nonlinear history. Is this good practice when working on a team?

• Checkstyle for C#?

  - by PSU_Kardi

  I'm looking to find something along the lines of Checkstyle for Visual Studio. I've recently started a new gig doing .NET work and realized that coding standards here are a bit lacking. While I'm still a young guy and far from the most experienced developer I'm trying to lead by example and get things going in the right direction. I loved the ability to use Checkstyle with Eclipse and examine code before reviews so I'd like to do the same thing with Visual Studio. Anyone have any good suggestions? Another thing I'd be somewhat interested in is a plug-in for SVN that disallows check-in until the main coding standards are met. I do not want people checking in busted code that's going to wind up in a code review. Any suggestions at this point would be great.

• Project management estimating time, budget and product pricing

  - by dr_hoppa

  I have been a software developer for a while but was not interested in the above topics, currently I am put in the position of wanting to learn more about them but don't have a clue where to begin. I have done task estimations and I can do decent ones, but have little/none experience in the field of budget/product pricing and would want to learn more. Do you have any suggestions of good resources that I could look up in order to learn more (eg. books, blogs, ...) This need arised while talking to a friend about management and he brought up management terms that I wasn't aware of (eg. KPI, ...)

• Google groups not finding discussion thread but regular google search does?

  - by Mathias Lin

  I'm having a problem with google groups and finding my own discussion threads. I go to the google group (in my case Android developer group) web view and try to search for my thread by entering the extact title of my thread. But it doesn't appear in the search results. On the other hand, when I search for the same title in the regular google web search, I get the thread right on top of the result list. I thought it might take a while until the groups index all new threads, but still after a few days, it still wouldn't show up. Sample: My thread is here: http://groups.google.com/group/android-developers/browse_thread/thread/0ab41d5056a25ce7 Doing a search for it in Google groups (will give one result, but not mine): http://groups.google.com/group/android-developers/search?group=android-developers&q=Strange+behaviour+with+mediaplayer+and+seekTo&qt_g=Search+this+group Search in Google web search (shows my thread as first result): http://www.google.de/search?sourceid=chrome&ie=UTF-8&q=Strange+behaviour+with+mediaplayer+and+seekTo

• Is there an ftp plugin for gedit that will let me work locally?

  - by RobertWHurst

  I'm trying to switch from a windows environment to Linux. I'm primarily PHP developer, but I do know quite a bit about other languages such as CSS, XHTML and Javascript. I need a way of editing my files locally because I work in a git repository and need to commit my saves. On windows I used Aptana and PDT. I'd save my files, upload via Aptana, then commit my work with git. I need to get a work flow going on my Linux machine now. If you know a better way to do this let me know, however my real question is, is there a plugin that allows gedit to upload files instead of working remotely?

• Avoiding cookies while requesting static content

  - by Abdel Olakara

  I just did an audit of one of my web application page (built using ASP.Net and running on development server) using Google chrome's developer tool. One particular warning caught my eyes: Serve static content from a cookieless domain (5)! Here is my screen shot (http://yfrog.com/7eauditresultp) as well. I would like to know is it possible to avoid cookies for these kind of requests. I see that there is no cookie requests for javascript files as well. I it possible to avoid cookies in the header for these files as well? and why didn't the browser attach cookies for javascript files and attach for CSS and image? Any thoughts and suggestions are welcome

• How do I authenticate a Twitter user and access the API without leaving my iPhone app?

  - by thebossman

  I'd like to allow users to send out Tweets from my iPhone app. That's all the functionality I need at the moment. From what I know of the Twitter API, there's a standard authentication mechanism, which allows the developer to include the user's name and password in the request string that the application sends to Twitter. This method will no longer be supported come June 30, 2010. Given the timeframe, the better other choice is oAuth. One of the caveats of oAuth is that it requires a UIWebView to pop up within the app to allow the user to enter his or her credentials or a PIN number. None of the Twitter apps on my phone do this, however: Tweetie, TweetDeck and Twitterific. I assume they're using the first authentication method, but it seems like Twitter wouldn't deprecate an API that would hurt the user experience across the board. There must be an alternative method--what am I missing?

• Please list here your deliberate practices in software development...

  - by JDelage

  What are your deliberate practices in relation with your work as a software developer / professional, or as a CS student? Deliberate practice are exercise and repetitions targeted specifically at an individual's weak points and meant to consistently stretch / grow someone's ability. It was described in this Anders Ericsson paper. To qualify as a deliberate practice, the exercise must satisfy the following: Is not inherently enjoyable. Is not play or paid practice. Is relevant to the skill being developed. Is not simply watching the skill being performed. Requires effort and attention from the learner. Often involves activities selected by a coach or teacher to facilitate learning. Please answer with one practice per answer. I'll seed the question with one possible answer.

• Is there any reason to use TFS 2010 in a micro ISV?

  - by kyrisu

  Yesterday I was checking VS2010 editions here and I've noticed that with VS10 with MSDN we get TFS2010 with 1 CAL. I'm a micro ISV (basically sole developer, many clients). I just want to save time - did anyone tried it in similar scenario? Are there any features worth looking into for such a small implementation? P.S. Right now I'm using GIT with gitextension - I'm happy with it, but I would like something more integrated with project management and bug tracking so I can show it to my clients when I'm working on their projects.

• CPU temperature monitoring C#

  - by Paul

  For a programming project I would like to access the temperature readings from my CPU and GPUs. I will be using C#. From various forums I get the impression that there is specific information and developer resources you need in order to access that information for various boards. I have a MSI NF750-G55 board. MSI's website does not have any of the information I am looking for. I tried their tech support and the rep I spoke with stated they do not have any such information. There must be a way to obtain that info. Any thoughts?

• Is programming in PHP easy?

  - by nik

  PHP is considered as an easy language of all, Why? Being an php developer, I haven't use any other language that much. And I know with php we gotta learn so much other things also like javascript ajax xml database jquery + all the cms like joomla, drupal, phpbb etc etc. And in web worls u always had to learn injecting maps, calendars, payment gatewaysetc Do learning other languages have these much dependencies? And if php easy than isn't it good thing to have easy language. I can't imagine to built a website in assembly language(Is it possible?)

• Accessing ArrayBuffer from PHP $_POST after xmlHTTPrequest send()

  - by Dan

  I'm following the tuitions on XMLHttpRequest 2 from : https://developer.mozilla.org/en/DOM/XMLHttpRequest/Sending_and_Receiving_Binary_Data and http://www.html5rocks.com/en/tutorials/file/xhr2/#toc-send-arraybuffer They're great tutorials for the client side, and here is a working extract from my script: var imagebuffer = new ArrayBuffer(size); // create the readonly memory buffer var imagedata= new Uint8Array(imagebuffer); // create a view to manipulate data // do some cool stuff with imagedata var exchange=new XMLHttpRequest(); exchange.open("POST",url,true); exchange.send(arraybuffer); So far so good, and I can see from the both client and server control panels that plenty of data is being transferred. Here's my problem: how do I access the ArrayBuffer with PHP at the server? I'm used to the $_POST superglobal wanting parameters passing from a HTML form so it can be accessed as an array but I can't find any reference for how to access this binary array and stick it in my MySQL database.

• dynamics CRM performance question

  - by tomo

  Hello Dynamics CRM gurus :) My boss asked me to do a research on available CMSes on market because cms we are using currently is rather a mess. For me as a .NET developer it would be great to choose and implement Dynamics CRM because of extensibility and perfect integration with .NET environment and well-known tools. All marketing blahbla sounds great but I'd like to know about common DISADVANTAGES, ISSUES concerning this system. The most important is how it is performing in a company with about 150 concurrent and very active users. I heard that is't really slow comparing to competitors system. Thanks in advance Best regards, Tomasz.

• Is ASP.Net Server Control, Postback Architecture failed in current Web 2.0 World.

  - by Lalit

  What i am looking around me is the drastically change in ASP.Net Architecture. More and more company are following the approach of JSON based wcf service in middle tier. Plain HTML based UI tier with JQuery/Ajax. No Postback at all, This contradicts the Default behaviour of Asp.Net Server Control/Code Behind Event handler/Postback. I am a Asp.Net Web Developer for around 4 years, and concerned about the future of ASP.Net. Is the Default Architecture of ASP.Net is Outdated at all? Does MVC or ASP.Net 4.0 Tries to solve the Issue?

• How sophisticated should be DAL?

  - by Andrew Florko

  Basically, DAL (Data Access Layer) should provide simple CRUD (Create/Read/Update/Delete) methods but I always have a temptation to create more sophisticated methods in order to minimize database access roundtrips from Business Logic Layer. What do you think about following extensions to CRUD (most of them are OK I suppose): Read: GetById, GetByName, GetPaged, GetByFilter... e.t.c. methods Create: GetOrCreate methods (model entity is returned from DB or created if not found and returned), Create(lots-of-relations) instead of Create and multiple AssignTo methods calls Update: Merge methods (entities list are updated, created and deleted in one call) Delete: Delete(bool children) - optional children delete, Cleanup methods Where do you usually implement Entity Cache capabilities? DAL or BLL? (My choice is BLL, but I have seen DAL implementations also) Where is the boundary when you decide: this operation is too specific so I should implement it in Business Logic Layer as DAL multiple calls? I often found insufficient BLL operations that were implemented in dozen database roundtrips because developer was afraid to create a bit more sophisticated DAL. Thank you in advance!

• Where does C# and the .NET Framework fail?

  - by Nate Bross

  In my non-programming life, I always attempt to use the approprite tool for the job, and I feel that I do the same in my programming life, but I find that I am choosing C# and .NET for almost everything. I'm finding it hard to come up with (realistic business) needs that cannot be met by .NET and C#. Obviously embedded systems might require something less bloated than the .NET Micro Framework, but I'm really looking for line of business type situations where .NET is not the best tool. I'm primarly a C# and .NET guy since its what I'm the most comfertable in, but I know a fair amount of C++, php, VB, powershell, batch files, and Java, as well as being versed in the web technologes (javascript, html/css). But I'm open minded about it my skill set and I'm looking for cases where C# and .NET are not the right tool for the job. The bottom line here, is that I feel that I'm choosing C# and .NET simply because I am very comfertable with it, so I'm looking for cases where you have chosen something other than .NET, even though you are primarly a .NET developer.

• How to setup Lighttpd as a proxy for cross-site requests?

  - by NilColor

  I want to setup my lighttpd server to proxy some requests (for ex. RSS requests) to other domains so i can fetch data using javascript. For example i'd like to fetch Atmo feed from internal Redmine (say http://code.internal.acme) to developer dashboard (say http://dashboard.internal.acme). I'd like to fetch it using JavaScript but i cant use something like JSONP and i don't want to use Flash for that. Currently i have this in my lighttpd.conf proxy.server = ( "/http-bind/" => ( ( "host" => "10.0.100.52", "port" => 5280 ) ) ) This way i can connect to our internal jabber server via Javascript. But i want more generic way... Something like proxy.server = ( "/proxy/{1}" => ( ( "url" => {1} ) ) )

• how to handle solutions/versioning in subversion

  - by Grayson Mitchell

  We are using ankhsvn to check in our .net code, however I have two issues with our setup that I want to resolve. 1\ I thought a key reason to have a tool like svn is that you can rollback to an earlier version of your codebase. If developers are just checking in code, then how can you get version 1.1 (say the current production build), out of subversion? 2\ In VS you have the concept of solutions, many solutions might use the same project. How do I make sure when a developer checks out a solution, they get the appropriate versions of the projects that belong to that solution?
