  • Python Mindstorms RCX

    - by Kyle Schmidt
    I've got 30 unopened Lego Mindstorms kits that I'd love to use in my intro programming class to do some simple robotics stuff at the end of the year. We're using Python in the class, so I'd prefer there to be a way for the kids to write the programs in Python. Unfortunately, these are old kits with RCX bricks - not the newer NXT ones, so most of the projects like NXT_Python can't help me. Is there any way to make that happen?

  • generating program structur (nodes) using bison and flex

    - by gruszczy
    I would like to write myself a pretty printer for java using bison and flex. I have written a pretty printer for a script language, but I was only writing visitors, which made the printing. How can I turn a program using my formal grammar into a tree of nodes (made using C++ classes), that afterwards I could visit using my visitor? Maybe you could give me some link with an example of this? What i need to put into flex/bison files?

  • Experienced developer trying to get outsourcing contract with current client.

    - by Mike
    I work for a major bank as a contract software developer. I've been there a few months, and without exception this place has the worst software practices I've ever seen. The software my team makes has no formal testing, terrible code (not reusable, hard to read, etc), minimal documentation, no defined development process and an absolutely sickening amount of waste due to bureaucratic overhead. Part of my contract is to maintain a group of thousands of very poorly written batch jobs. When one of the jobs fails (read: crashes), it's a developers job to look at the source, figure out what's wrong, fix it, and check it in. There is no quality assurance process or auditing of the results whatsoever. Once the developer says "it works" a manager signs off and it goes into production. What's disturbing is that these jobs essentially grab market data and put it into a third-party risk management system, which provides the bank with critical intelligence. I've discovered the disturbing truth that this has been happening since the 90s and nobody really has evidence the system is getting the correct data! Without going into details, an issue arose on Friday that was so horrible I actually stormed out of the place. I was ready to quit, but I decided to just get out to calm my nerves and possibly go back Monday. I've been reflecting today on how to handle this. I have realized that, in probably less than 6 months, I could (with 2 other developers) remake a large component of this system. The new system would provide them with, as primary benefits, a maintainable codebase less prone to error and a solid QA framework. To do it properly I would have to be outside the bank, the internal bureaucracy is just too much. And moreover, I think a bank is fundamentally not a place that can make good software. This is my plan. Write a report explaining in depth all the problems with their current system Explain why their software practices fail and generate a tremendous amount of error and waste. Use this as the basis for claiming the project must be developed externally. Write a high level development plan, including what resources I will require Hand 1,2,3 to my manager, hopefully he passes it up the chain. Worst case he fires me, but this isn't so bad. Convinced Executive decides to award my company a contract for the new system I have 8 years experience as a software contractor and have delivered my share of successful software products, but all working in-house for small/medium sized companies. When I read this over, I think I have a dynamite plan. But since this is the first time doing something this bold so I have my doubts. My question is, is this a good idea? If you think not, please spare no detail.

  • Anyone know of a good open source spam checker in java or c#?

    - by Spines
    I'm creating a site where users can write articles and comment on the articles. I want to automatically check to see if a new article or comment is spam. What are good libraries for doing this? I looked at bayesian classifier libraries, but it seems that I would have to gather a large amount of samples and classify them all as spam or not spam myself... I'm looking for something that can hopefully just tell me right out of the box.

  • Java JList model

    - by Alaa
    How can I make a list model from a JList in order to be able to insert an item into it. I want to use this method: addElement(java.lang.Object item) I found an explanation here, but the problem is that ListModel is an interface and even if I write an implementation and override its method, I can't use the addElement() method

  • Turtle Graphics as a Haskell Monad

    - by iliis
    I'm trying to implement turtle graphis in Haskell. The goal is to be able to write a function like this: draw_something = do fordward 100 right 90 forward 100 ... and then have it produce a list of points (maybe with additional properties): > draw_something (0,0) 0 -- start at (0,0) facing east (0 degrees) [(0,0), (0,100), (-100,100), ...] I have all this working in a 'normal' way, but I fail to implement it as a Haskell Monad and use the do-notation. The basic code: data State a = State (a, a) a -- (x,y), angle deriving (Show, Eq) initstate :: State Float initstate = State (0.0,0.0) 0.0 -- constrain angles to 0 to 2*pi fmod :: Float -> Float fmod a | a >= 2*pi = fmod (a-2*pi) | a < 0 = fmod (a+2*pi) | otherwise = a forward :: Float -> State Float -> [State Float] forward d (State (x,y) angle) = [State (x + d * (sin angle), y + d * (cos angle)) angle] right :: Float -> State Float -> [State Float] right d (State pos angle) = [State pos (fmod (angle+d))] bind :: [State a] -> (State a -> [State a]) -> [State a] bind xs f = xs ++ (f (head $ reverse xs)) ret :: State a -> [State a] ret x = [x] With this I can now write > [initstate] `bind` (forward 100) `bind` (right (pi/2)) `bind` (forward 100) [State (0.0,0.0) 0.0,State (0.0,100.0) 0.0,State (0.0,100.0) 1.5707964,State (100.0,99.99999) 1.5707964] And get the expected result. However I fail to implement this as an instance of Monad. instance Monad [State] where ... results in `State' is not applied to enough type arguments Expected kind `*', but `State' has kind `* -> *' In the instance declaration for `Monad [State]' And if I wrap the list in a new object data StateList a = StateList [State a] instance Monad StateList where return x = StateList [x] I get Couldn't match type `a' with `State a' `a' is a rigid type variable bound by the type signature for return :: a -> StateList a at logo.hs:38:9 In the expression: x In the first argument of `StateList', namely `[x]' In the expression: StateList [x] I tried various other versions but I never got it to run as I'd like to. What am I doing wrong? What do I understand incorrectly?

  • How does ruby's rb_raise stop the execution of the c function calling it?

    - by Adrian
    If you write a ruby method as a function in C that uses rb_raise, the part of the function after the call will not get excecuted and the program will stop and you will think that rb_raise used exit(). But if you rescue the exception in ruby, like: begin method_that_raises_an_exception rescue end puts 'You wil still get here.' The ruby code will go on, but your function will stop excecuting. How does rb_raise make this happen?

  • What is your solution to the FizzBuzz problem?

    - by saniul
    See here Write a program that prints the numbers from 1 to 100. But for multiples of three print "Fizz" instead of the number and for the multiples of five print "Buzz". For numbers which are multiples of both three and five print "FizzBuzz". Disclaimer: I do realize this is easy, and I understand the content of the Coding Horror post I just linked to

  • Javascript Sandbox

    - by Louis
    I want to have developers write some custom apps for a site in Javascript but I want to sandbox it so they can't do anything naughty like redirect the user, set the body display to none etc etc. I have a namespace in Javascript where all the functions they'll ever need exist in there so I was thinking to create a sandbox would be a matter of: with(Namespace) { //App code goes here where they can only access Namespace.* } How is easy is it to get around this and what other methods can be done? Would rather not have to moderate every submitted app.

  • Calling COM Library From XBAP

    - by Benny
    I am trying to call an old COM library from my XBAP and continue to receive the following exception: System.AccessViolationException was unhandled Message: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. I have tried adding the HKLM value for RunUnrestricted to no avail. I don't get anything else but this error when calling the library. Any ideas? (This library even works from a pure ASP.NET app)
