• Are there some good and modern alternatives to Javadoc?

  - by ivan_ivanovich_ivanoff

  Let's face it: You don't need to be a designer to see that default Javadoc looks ugly. There are some resources on the web which offer re-styled Javadoc. But the default behaviour represents the product and should be as reasonably good-looking. Another problem is the fact that the usability of Javadoc is not up-to-date compared to other similar resources. Especially huge projects are hard to navigate using Firefox's quick search. Practical question: Are there any standalone (desktop) applications which are able to browse existing Javadoc in a more usable way than a browser would? I'm thinking about something like Mono's documentation browser. Theoretical question: Does anyone know, if there some plans to evolve Javadoc, in a somehow-standardized way? EDIT: A useful link to Sun' wiki on this topic.

• How do you make an installer for your python program

  - by Malcolm2608

  Im new to python, but I was thinking about making a program with python to give to my friends. They don't know much about computers so if I asked them to install python by them selves they couldn't do it, but what if I could make an installer that downloads some version of python that only has what is needed for my file to run and make an exe file that would run the .py file in its own python interpreter . I also did a Google search and saw the freezing applications I could use to make the code into exe files to distribute (cx_freeze I use python 3.2), but not all of my friends have Windows computers and I rather Have my program so in each new version it auto updates by making a patch to .py file and not completely re-installing it .

• link_to_remote does not generate correct url in Haml

  - by mathee

  In Haml, I've been trying to get the following link_to_remote call to work. It's called from the /questions/new view. #{link_to_remote image_tag('x.png'), :url => {:controller => 'questions', :action => 'remove_tag_from_cart'}} I've tried the following variations. #{link_to_remote image_tag('x.png'), :url => {:controller => :questions, :action => :remove_tag_from_cart}} #{link_to_remote image_tag('x.png'), :controller => 'questions', :action => 'remove_tag_from_cart'} #{link_to_remote image_tag('x.png'), :controller => :questions, :action => :remove_tag_from_cart} In every case, I get the following link: /questions/new#. I'm not sure why! I also have the following in routes.rb, thinking that was the problem... map.connect ':controller/remove_tag_from_cart', :action => 'remove_tag_from_cart'

• Where can I find a deliberately insecure open source web application?

  - by Phil Laliberte

  As a developer, I've learned that I usually gain a better understanding of best/worst practices through experience. The area of web application security isn't really somewhere where my organization can afford to let developers learn through trial and error. So looking for a hands-on approach to knowledge sharing of best practices in web application security, I was thinking that it would be useful to have an open source application that was deliberately built to be insecure in order to help teach junior developers about application security. Does anyone out there know where to find something like this?

• Delegation, is this just opinionated or is there a common pattern?

  - by user1446714

  If I have a java class containing substantial code and I wish to add extra features, am I right in thinking the delegate class would have the additional features added as methods. Then my original class would create the delegate object and just call the extra functionality via the delegate instance? I am being told by somebody else that my original class should become the delegate and that the class containing the new functionality should contain an instance of the original class, to use as a delegate? This seemed a little backward to me, because there would be far more delegate calls because most of the code is now in the delegate.... I was always under the impression the delegate object would contain the additional new behaviour and an instance of it would be in the original class to inboke the new behaviour from?

• Built in raytracing?

  - by acidzombie24

  Relating to this question i was wondering if .NET has any libs (or a function) i can use to detect if one point collides with another. I am not sure what angles i should use but is there some function like this func(point src, rect target, angle, distanceOfVision, listPointOrRectOfWalls) Pretty unlikely but i dont know a formula or how to start. Its a quick and dirty prototype. I am thinking of writing the func about but dropping angle and just make line of sight a rectangle and check if any points is between src and target.

• What would you like to see in a book about Rails 3?

  - by Ryan Bigg

  Hello, I'm thinking of writing a book about Rails 3 and I have a basic idea of what I want to write about, but really what I need is that little bit of polish from the community. The book is planned to cover: A little bit of Ruby Version control using Git Testing using RSpec & Cucumber Life without Rails (Rack) Developing an application in Rails (vague, I know, sorry! Work in progress) Javascript testing using Selenium Background processing Document databases (a tentative maybe, at this stage) Monitoring an application And a little more. So, I leave this question for you: What do you want to see in a book about Rails 3, which goes from "This is Rails" to "This is how Rails scales"?

• How and when to log account access login with PHP?

  - by Nazgulled

  I want to implement a basic login system in some PHP app where no cookies will be involved. I mean, the user closes the browser and the login expires, it will remain active during the browser session (or if the user explicitly logs out) otherwise. I want to log all this activity and I'm thinking that every time the user refreshes the page, opens a different link or logs out, I record that time as the last access made by that user, overwriting the previous access log. But my problem is when and how should I insert another record into the database instead of overwriting the last one? Should I just define a timeout and if the last access was made above that timeout, another log should be inserted into the database? Should the session expire too after that timeout? Or is there a better way? Ideally, I would like to log the "log out action" when the browser was closed, but I don't think there's a way to detect that is there? Suggestions?

• Need help with REGEXP_REPLACE

  - by Randy

  hey regex guru's I have a data column that contains a substring similar to this: 'This is a string with ID=123 contained inside' i need to replace the ID=123 with another fixed string say ID=1 i have a working REPLACE call that swaps out the values correctly, but this only works on a known original id number. I can extend to make it work when the number of digits are known by using some substr magic, however, the id number may have an arbitrary number of digits, so i'm thinking regex. any help with the regex magix to grab the entire ID=999 substring no matter how many digits would be very helpful. thanks

• iOS - Application logging test and production code

  - by Peter Warbo

  I am doing a bunch of logging when I'm testing my application which is useful for getting information about variable state and such. However I have read that you should use logging sparsely in production code (because it can potentially slow down your application). But my question is now: if my app is in production and people are using it, whenever a crash (god forbid) occurs, how will I be able to interpret the crash information if I have removed the logging statements? Then I suppose I will only have a stacktrace for me to interpret? Does this mean I should leave logging in production code only WHERE it's really essential for me to interpret what has happened? Also how will the logging statements relate to the crash reports? Will they be combined? I'm thinking of using Flurry as analytics and crash reports...

• What's the point of having to provide a cacheName for NSFetchedResultsController?

  - by dontWatchMyProfile

  NSFetchedResultsController *frc = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:moc sectionNameKeyPath:nil cacheName:@"Root"]; Why do we have to think about a cacheName? How important is this decision? What would happen if there are two NSFetchedResultsController instances using the exact same cacheName? Does that matter? Is that some kind of singleton stuff? Thinking about Core Animation, there's also this strange animationID parameter, but setting it to the exact same thing for dozens of simultaneous animations doesn't hurt the animations at all. So I guess it's probably the same thing here...or not?

• iPhone: Custom UITableViewCell with multiple areas that respond to taps?

  - by Nick

  I've been asked to create a custom UITableViewCell with multiple areas that can be tapped. These areas won't have buttons or any graphics - they'll be invisible. 3 different methods will be called depending on which third of the cell the user taps i.e. || decrementFooCount || viewFooDetails || incrementFooCount || The cell has a few labels on it that need to be visible at all times - the fooName and fooCount. I'm thinking perhaps three hidden UIButtons over the cell? I also need to maintain the swipe to delete default behavior.

• Do there any dev who wrote iPhone wifi/bluetooth multiplay before?

  - by Jerry1923

  Hi there, do there any dev who wrote iPhone wifi/bluetooth multiplay before? Recently, I'm trying to make my latest game Doodle Kart to have mulityplay via bluetooth. But I found that there are hugh data need to share between the 2 devices. -your car's position and direction -your car's status(it is in normal state, it is hitting by bullet, it is falling into to hole....) -CUP car's position, dicretion, and their status -items position and status (pencil, bullet...) I'm thinking about one device calculate all the things, and the other device just wait and receive the data to display on the screen. Does it make sense? Hey, I should ask you the most important question first: Do you think it's possible to make bluetooth multiplay work on my game? It's just too much data need to share between the device.

• Icons: How does a developer with no design skill make his/her application icons look pretty?

  - by Martin

  I probably spend far too much time trying to make my visual interfaces look good, and while I'm pretty adept at finding the right match between usability and style one area I am hopeless at is making nice looking icons. How do you people overcome this (I'm sure common) problem? I'm thinking of things like images on buttons and perhaps most important of all, the actual application icon. Do you rely on third party designers, in or out of house? Or do you know of some hidden website that offers lots of icons for us to use? I've tried Google but I seem to find either expensive packages that are very specific, millions of Star Trek icons or icons that look abysmal at 16x16 which is my preferred size on in-application buttons. Any help/advice appreciated.

• PHP, manipulating images and thumbnails?

  - by learner.php

  I am using php and mysql. I allow my registered users to upload photos, the photos are store in filesystem format, then I will keep the original/max size of : width: 1600px and heigh: 1200px. In the user profile page, I would like to display the image, it maybe one of the 5 types of thumnails: 500x500, 300x300, 200x200, 100x100 or 50x50. What is the best way to create the thumbnails, here are my current solutions: I am thinking of create 1 thumbnail, then from that thumbnail, i will resize in [img src="" width="XX"] tag, alternatively, store the different thumbnails size in database, then get and display it Create 5 thumbnails for each photos? (I am afraid this is a bad way) Whats the best practices?

• Branch for each developer in GIT repo

  - by Peter

  I'd like to move my project to GitHub from local svn repository. Multiple developers are curently working on this project. I was thinking that each developer should have their own branch in which they would commit changes. When manager review their work, he will merge it into master branch. I don't want separate repository for each developer as GitHub has limited number of private repositories. Is this a good idea? What are other alternatives?

• Rolling back or re-creating the master branch in git?

  - by Matthew Savage

  I have a git repo which has a few branches - there's the master branch, which is our stable working version, and then there is a development/staging branch which we're doing new work in. Unfortunately it would appear that without thinking I was a bit overzealous with rebasing and have pulled all of the staging code into Master over a period of time (about 80 commits... yes, I know, stupid, clumsy, poor code-man-ship etc....). Due to this it makes it very hard for me to do minor fixes on the current version of our app (a rails application) and push out the changes without also pushing out the 'staged' new features which we don't yet want to release. I am wondering if it is possible to do the following: Determine the last 'trunk' commit Take all commits from that point onward and move them into a separate branch, more or less rolling back the changes Start using the branches like they were made for. Unfortunately, though, I'm still continually learning about git, so I'm a bit confused about what to really do here. Thanks!

• Rails - Preventing users from contributing to website when there score is too low - callback / obser

  - by adam

  A User can add a Sentence directly on my website, via twitter or email. To add a sentence they must have a minimum score. If they don't have the minimum score they cant post the sentence and a warning message is either flashed on the website, sent back to them via twitter or email. So I'm wondering how best to code this check. Im thinking a sentence observer. So far my thoughts are in before_create score_sufficient() - score ok = save - score too low = do not save In the case of too low i need to return some flag so that the calling code can then fire off teh relevant warning. What type of flag should I return? False is too ambiguous as that could refer to validation. I could raise an exception but that doesn't sound right or I could return a symbol? Is this even the right approach? What's the best way to code this?

• PC reboots spontaenously: debugging tips [closed]

  - by aaron

  I swapped my core 2 duo for a quad core recently, and generally things run fine, but every now and then my computer just restarts. I don't even get a blue screen (Vista 32). Core temp isn't a problem. My thinking is that my power supply is inadequate, but I haven't been able to test that (one idea was to under clock the cpu to see if that helped, but going up in speed was the only simple thing to do in the BIOS) Two cases where I semi-consistanly get problems: - Borderlands windowed after some period of time (and some other games, but Borderlands does it pretty regularly) - watching a video (e.g. quicktime/vlc) and having another video running Another thought is non-cpu heat? Maybe the graphics card? Any thoughts on how to track this down appreciated. Thanks!

• Parsing/executing C# code in C++ (on Linux)?

  - by Stick it to THE MAN

  I want to be able to add scripting functionality to my application. One of the language bindings I am considering is C# (and possibly VB.Net). The challenge is this: My application is developed in C++ My application runs on Linux I am aware of Mono, but I dont know (as yet), what is required to allow my C++ appliaction (running on linux), to be scriptable with .Net languages. Is this feasible? Am I crazy for even thinking of doing this? If I'm not crazy, can anyone provide some guidelines on how to go about implementing this? Help, tips, ideas, suggestions anyone?

• When did C++ get nested classes?

  - by Parappa

  Somehow I never noticed until today that C++ supports nested classes. This surprised me because when I was learning C++ back in the '90s, I specifically remember nested classes being something that Object Pascal and Java had, but which C++ did not. I asked an old programmer friend about it and he concurred that he recalls C++ not having nested classes. Is my recollection of C++ not having nested classes mistaken, or were they actually added to the standard at some point in the past fifteen years? I tried searching Google for information on this topic and I haven't come up with anything helpful yet. It could also be that I'm thinking of nested functions, which Pascal certainly supports but C does not.

• Indexing datetime in MySQL

  - by User1

  What is the best way to index a datetime in MySQL? Which method is faster: Store the datetime as a double (via unix timestamp) Store the datetime as a datetime The application generating the timestamp data can output either format. Unfortunately, datetime will be a key for this particular data structure so speed will matter. Also, is it possible to make an index on an expression? For example, index on UNIX_TIMESTAMP(mydate) where mydate is a field in a table and UNIX_TIMESTAMP is a mysql function. I know that Postgres can do it. I'm thinking there must be a way in mysql as well.

• template function roundTo int, float -> truncation

  - by Oops

  Hi, according to this question: http://stackoverflow.com/questions/2833730/calling-template-function-without-type-inference the round function I will use in the future now looks like: template < typename TOut, typename TIn > TOut roundTo( TIn value ) { return static_cast<TOut>( value + 0.5 ); } double d = 1.54; int i = rountTo<int>(d); However it makes sense only if it will be used to round to integral datatypes like char, short, int, long, long long int, and it's unsigned counterparts. If it ever will be used with a TOut As float or long double it will deliver s***. double d = 1.54; float f = roundTo<float>(d); // aarrrgh now float is 2.04; I was thinking of a specified overload of the function but ... that's not possible... How would you solve this problem? many thanks in advance Oops

• Is it possible for a Grails Domain to have no 'id'?

  - by firnnauriel

  Is it possible to create a table that has no 'id'? For example, this is my domain: class SnbrActVector { int nid String term double weight static mapping = { version false id generator: 'identity' } static constraints = { } } When I run this SQL statement, it fails: insert into snbr_act_vector values (5, 'term', 0.5) I checked the table and 'id' is already set to autoincrement. I'm thinking that another option is to remove the 'id' itself. Or is there another workaround for this? Please assume that it is not an option to change the givent SQL statement.
