  • Simulating brush strokes for painting application

    - by DrRobot
    I'm trying to write an application that can be used to create pictures that look like paintings using simulated brush strokes. Are there any good sources for simple ways of simulating brush strokes? For example, given a list of mouse positions that the user has dragged the mouse through, a brush width and a brush texture, how do I determine what to draw to the canvas? I've tried angling the brush texture in the direction of the mouse movement and dabbing several brush texture images along the path, but it doesn't look great. I think I'm missing something where the brush texture should shrink and grow on corners. Any simple to follow links would be appreciated. I've found complex academic papers on simulating e.g. oil paints but I just want a basic algorithm to use that produces OK results if possible.

  • Problem with do construct in haskell

    - by Anonymous Coward
    Hello everyone I'm trying to learn Haskell and want to write a small program which prints the content of a file to the screen. When I load it into GHCi I get the following error: The last statement in a 'do' construct must be an expression I know this question has be asked already here: Haskell — “The last statement in a 'do' construct must be an expression”. Even though my code is very similar I still can't figure out the problem. If anyone could point out the problem to me I'd be very thankful. module Main (main) where import System.IO import System(getArgs) main :: IO() main = do args <- getArgs inh <- openFile $ ReadMode head args printFile inh hClose inh printFile :: Handle -> IO () printFile handle = do end <- hIsEOF handle if end then return () else do line <- hGetLine handle putStrLn line printFile handle

  • How to make a daemon which will accept arbitrary commands

    - by Jono
    Right now the program can be launched in a linux terminal. Once running you can type various commands and the program will do stuff on the machine until the user quits. I would like to make the program into a service that the user runs and it goes to the background. Then the user should be able to make commands to it. Like start and stop, and write something to a log and whatever else my program does. Note that I need to send it arbitrary commands that my program will handle, not just start and stop. Maybe this means it is no longer a daemon - I dont know. How do I do this? Also, if this is not too hard, I would like to be able to run multiple instances of this service. But it is not essential.

  • change/part doesn't work as expected with parse

    - by Rebol Tutorial
    According to http://www.rebol.com/docs/core23/rebolcore-15.html You can use change/part to parse and replace but that doesn't work well with this where I just try to replace the block <mytag > ... </mytag> by "MyString" content: {<mytag id="a" 111111111111111> </mytag> aaaaaaaaaaaaaaa aaaaaaaaaaaaaaa <mytag id="b" 22222222222222222> </mytag> <mytag id="c" 3333333333333> </mytag> aaaaaaaaaaaaaaa aaaaaaaaaaaaaaa <mytag id="d" 444444444444444> </mytag> } mytag: [ to {<mytag} start: ( ) thru {<mytag} to {id="} thru {id="} copy ID to {"} thru {"} to {</mytag>} thru {</mytag>} ending: (change/part start "mystring" ending) mark: ( write clipboard:// mark input) ] rule: [any mytag to end] parse content rule

  • Server-side Javascript (aspx.cs) Attributes.Add Code to Change a Label's text

    - by DFM
    I am trying to change a label's text by using server-side javascript (onclick) and C# within the page_load event. For example, I would like to write something like the following: Label1.Attributes.Add("onclick", "Label2.text='new caption'") Does anyone know the correct code for this? Also, what is this type of code referred to; is it just javascript or javascript in C# or is there a specific name? Lastly, does a book or online resource exist that lists the choices of control.attributes.add("event", "syntax") code to use with C#? Thank you, DFM

  • Attaching catalog with SQL Authentication credentials attaches it as Read-Only

    - by Nissim
    Hello, As part of our product's installation process, a database is attached to the server. We use EXEC sp_attach_db in order to attach it to MSSQL. The problem occures when we try to attach it with "SQL Authentication" connection string - the database is attached to the server as read-only, thus preventing any write access from being performed This is driving us nuts... it's working just fine with Windows Authentication, and the only difference is the connection string... I tried googling for it but no mention for such a scenario is found. Any ideas anyone? It's important to mention that the MDF/LDF physical files are not set with "ReadOnly" attribute, so this is not the problem.

  • Access DB with SQL Server Back End

    - by uyuni99
    I have an old Access application that has a lot of code in forms and reports. The database is getting too large and I am thinking of moving the back end to SQL Server. My requirements are as follows: The DB needs to be multiuser and the users (3-5) will need to log in over the web I would prefer not to re-write the forms and reports in ASP or some other web front end. When I think about my choices, I see them as: Have an Access ADP front end and allows remote log-in to the server where it is stored. Not sure if it is possible for 2 users to simultaneously log in Distribute an ADP front end to the users, but I am not sure if it is possible to connect to a SQL Server back end over the internet, and the network traffic may be an issue. Any other solution? I appreciate all help. u

  • How to find validity of a string of parentheses, curly brackets and square brackets?

    - by Rajendra
    I recently came in contact with this interesting problem. You are given a string containing just the characters '(', ')', '{', '}', '[' and ']', for example, "[{()}]", you need to write a function which will check validity of such an input string, function may be like this: bool isValid(char* s); these brackets have to close in the correct order, for example "()" and "()[]{}" are all valid but "(]", "([)]" and "{{{{" are not! I came out with following O(n) time and O(n) space complexity solution, which works fine: Maintain a stack of characters. Whenever you find opening braces '(', '{' OR '[' push it on the stack. Whenever you find closing braces ')', '}' OR ']' , check if top of stack is corresponding opening bracket, if yes, then pop the stack, else break the loop and return false. Repeat steps 2 - 3 until end of the string. This works, but can we optimize it for space, may be constant extra space, I understand that time complexity cannot be less than O(n) as we have to look at every character. So my question is can we solve this problem in O(1) space?

  • Which is the UI technology of the future considering: eye-candy-effect, interactivity (gestures, voc

    - by user193655
    If you had to write a next-gen application, in which on the surface (UI) you need some "futuristic features", by considering the following aspects which is the choice you'd make? 1) eye-candy: cool UI, 3D, Effects, nice graphics, sound transitions... 2) user interaction: not only mouse and keyboard but touch, voice and more.... + user interactivity aspect, which is the technology you'd choose? 3) X-platform: this is to have some X-platform discussion. Of course single platform technologies (as WPF) have may be some more power, anyway in a general discussion considering X-platform as a resource is important 4) available components: of course the coolest technology with no available components is may be an option for a component developer but not for an application developer My question is generic, but anyway * have in mind data-driven apps, not pure multimedia apps, videogames, ....

  • How to loop in excel without VBA or macros?

    - by Jeff
    Is there a better way for me to write this formula? Did some googling on "excel loops," but no luck. I don't have VBA or macros installed (it's not an option to install them, unfortunately). =IF('testsheet'!$C$1 <= 99,'testsheet'!$A$1,"") & IF('testsheet'!$C$2 <= 99, 'testsheet'!$A$2,"") & IF('testsheet'!$C$3 <= 99, 'testsheet'!$A$3,"") & ... and so on through !$C$40, !$A$40 ... As it is, I'll have to repeat the above code 40 times in each cell and I have over 200 cells which need the code. sniff I'm pretty good with PHP/SQL, but just learning Excel.

  • NASM: Count how many bits in a 32 Bit number are set to 1.

    - by citronas
    I have a 32 Bit number and want to count know how many bits are 1. I'm thinking of this pseudocode: mov eax, [number] while(eax != 0) { div eax, 2 if(edx == 1) { ecx++; } shr eax, 1 } Is there a more efficient way? I'm using NASM on a x86 processor. (I'm just beginning with assembler, so please do not tell me to use code from extern libraries, because I do not even know how to include them ;) ) (I just found http://stackoverflow.com/questions/109023/best-algorithm-to-count-the-number-of-set-bits-in-a-32-bit-integer which also contains my solution. There are other solutions posted, but unfortunatly I can't seem to figure out, how I would write them in assembler)

  • Select all rows where there is not a specific value in a different table

    - by JMC Creative
    This is a wordpress installation, but I think the question is more of a general sql question. First off, my sql skills are not great (I don't even know if I'm following the correct format for illustrating the db). I've got two tables: wp_posts : ID (pk) | post_name | ... ---------------------------- 45 | "Hello" 91 | "Funny" 16 | "Wheat" wp_postmeta : post_id (fk) | meta_key | meta_value | ... ------------------------------------------------ 45 | "_edit_lock" | 5789789834 45 | "fizzbizz" | "foobar" 91 | "_something" | "teve" 16 | "_edit_lock" | 8798756 I would to select all rows in wp_posts where there is NO corresponding row in wp_postmeta where meta_key = "fizzbizz" I originally had this query, but someone pointed out that it would not retrive ID = '16' in the above case. How would I correctly write the query? $pageposts = $wpdb->get_results(" SELECT * FROM wp_posts p JOIN wp_postmeta m ON p.ID = m.post_id WHERE m.meta_key <> 'fizzbizz' ORDER BY p.post_date DESC; ");

  • [macosx]does dlopen call open and read functions?

    Hello, I've intercepted(interposed) dlopen function under MacOS X and some other functions. I see how my applications calls dlopen in the log, but don't find anything related to open/read functions after dynamic library was dlopened. How does the system accesses and reads the dynamic library file? I've looked at the source code of dyld, and it does call open/read on dlopen. Can anybody let me know what I'm missing? intercepted functions: dlopen, open, read, write, access, all stat functions, close, etc. thanks, any help is highly appreciated.

  • Passing variable string to create arrays (Android)

    - by dweebsonduty
    Hello all, I am a newb to Android and Java and want to write a funtion that will display a list based on a varable that I pass to the function. The function is below and the code below creates an array out of a string called type, but what I want to do is pass it a variable string and have it build a list based on that string. So if I wanted the type list I would say list_it("type") But if I try something like getResources().getStringArray(R.array.thelist); it doesn't work. Can someone point me in the right direction? public void list_it(String thelist){ String[] types = getResources().getStringArray(R.array.type); ArrayAdapter<String> mAdapter = new ArrayAdapter<String>(this, R.layout.list_item1, types); setListAdapter(mAdapter); ListView lv = getListView(); lv.setTextFilterEnabled(true); }

  • How to create a bash function with variable parameters/arguments to grep several keywords/tags

    - by CornSmith
    I'm using the :!grep "tag1" filename | grep "tag2" filename | grep -n "tag3 or more" filename command in vim to search for my code snippets based on their tags (a simple comment at the top of a snippet) in one big file. I use snippets to remember tricky things. This is painful to write out each time. I'd like to make an alias, or function to do something like this: :!greptag tag1 tag2 ... tag39 And it should search the current doc and return the lines with all the tags on them. Vim is set to interactive shell mode so that it can parse my bashrc for aliases/functions. set shellcmdflag=-ic How can I construct a function that allows for variable arguments like this in bash?

  • Sorting 1 million 8-digit numbers in 1MB of RAM

    - by Favourite Chigozie Onwuemene
    I have a computer with 1M of RAM and no other local storage. I must use it to accept 1 million 8-digit decimal numbers over a TCP connection, sort them, and then send the sorted list out over another TCP connection. The list of numbers may contain duplicates, which I must not discard. The code will be placed in ROM, so I need not subtract the size of my code from the 1M. I already have code to drive the ethernet port and handle TCP/IP connections, and it requires 2k for its state data, including a 1k buffer via which the code will read and write data. Is there a solution to this problem?

  • MPI Large Data all to all transfer

    - by csslayer
    My application of MPI has some process that generate some large data. Say we have N+1 process (one for master control, others are workers), each of worker processes generate large data, which is now simply write to normal file, named file1, file2, ..., fileN. The size of each file may be quite different. Now I need to send all fileM to rank M process to do the next job, So it's just like all to all data transfer. My problem is how should I use MPI API to send these files efficiently? I used to use windows share folder to transfer these before, but I think it's not a good idea. I have think about MPI_file and MPI_All_to_all, but these functions seems not to be so suitable for my case. Simple MPI_Send and MPI_Recv seems hard to be used because every process need to transfer large data, and I don't want to use distributed file system for now.

  • AES Key encoded byte[] to String and back to byte[]

    - by Tom Brito
    In the similar question "Conversion of byte[] into a String and then back to a byte[]" is said to not to do the byte[] to String and back conversion, what looks like apply to most cases, mainly when you don't know the encoding used. But, in my case I'm trying to save to a DB the javax.crypto.SecretKey data, and recoverd it after. The interface provide a method getEncoded() which returns the key data encoded as byte[], and with another class I can use this byte[] to recover the key. So, the question is, how do I write the key bytes as String, and later get back the byte[] to regenerate the key?

  • (Cocoa) Can I Subclass and Delegate at the same time?

    - by Alvin
    @interface ClassB <ClassADelegate> : ClassA id <ClassBDelegate> delegate; @end As the code says, ClassB subclasses from ClassA and handles the formation protocol of Class A. However, the variable "delegate" will be duplicated. (ClassA also has "delegate") In fact, it can be done without subclassing, but it seems the code is cumbersome, i.e., to use a variable/function of ClassA, I need to write [[ClassB classA] doSomething] instead of [classB doSomething], where doSomething: is a function of ClassA. Are there any tidy way for me to do that?
