• UIViewScrollviw UITableView subview scrolling. IOS

  - by user1484810

  I have a UIScrollview with a UITableview subview. The UIScrollview scrolls the UITableView horizontally. The UITable view naturally scrolls up and down. If a user places their finger on the UitableView, and moves (swipes) horizontally, The delegate method below is invoked (void)scrollViewDidScroll:(UIScrollView *)scrollView with scrollView isEqual theUIScrollView If the user lifts their finger and places it back down on the UITableView and moves in a vertical direction The delegate method below is invoked (void)scrollViewDidScroll:(UIScrollView *)scrollView with scrollView isEqual = theUITable If however the user places their finger and moves in a horizontally (void)scrollViewDidScroll:(UIScrollView *)scrollView with scrollView isEqual theUIScrollView If the user then moves the finger (without lifting it) in a vertical direction. delegate method scrollViewDidScroll is not invoked at all. (The reverse is true too.) I note that the "Pulse News" app seems to behave in the above manner.. Ultimately I want to figure out how to get the UITableView and UIScrollview moving in a "unidirectional" fashion, with one finger kept on the screen. Thanks...

• Display small form while main form is "locked"

  - by daemonsvk

  Hi there, i'm thinking about writing a WPF program that would require login and password at the app startup. I thought about small form with two textboxes as a login form. User will have to fill in his details and then the main form of the application will be unlocked. How will you solve this? Thanks for your answers, daemonsvk

• Building vs. Compiling (Java)

  - by sixtyfootersdude

  Thinking that the answer to this is pretty obvious but here it goes: When I am working on a small project for school (in java) I "compile" it. On my coop we are using ant to "build" our project. I think that compiling is a subset of building. Is this correct? What is the difference between building and compiling?

• Curious: Could LLVM be used for Infocom z-machine code, and if so how? (in general)

  - by jonhendry2

  Forgive me if this is a silly question, but I'm wondering if/how LLVM could be used to obtain a higher performance Z-Machine VM for interactive fiction. (If it could be used, I'm just looking for some high-level ideas or suggestions, not a detailed solution.) It might seem odd to desire higher performance for a circa-1978 technology, but apparently Z-Machine games produced by the modern Inform 7 IDE can have performance issues due to the huge number of rules that need to be evaluated with each turn. Thanks! FYI: The Z-machine architecture was reverse-engineered by Graham Nelson and is documented at http://www.inform-fiction.org/zmachine/standards/z1point0/overview.html

• Computer Vision Website Image Slideshow help

  - by msandbot

  Hi, I'm making an online display of the output of a computer vision algorithm. After running the algorithm I am left with a folder of about 1000 16 bit .tiff files. I need to put those on the website in a list for so that the researchers can click through and find the list. Also there needs to be an image frame with an "animated gif" feel that can be started stopped and played in reverse. Any ideas on the best way to do this? What language to use? I made a simple website in Ruby on Rails but I don't know if it has the capabilities to do what I require.

• Git/SVN for asp.net development instead of VSS?

  - by jrutter

  At work, we are using ASP.net 2.0 and VSS. VSS is a beast, we are continually having issues with people checking out files and there is no branching - makes it crazy. I know SVN/GIT is mainly used by open source developers, are there any downsides to ASP.NET developers using it? I have been pushing for SVN internally, but am thinking GIT might also be a great option. Our team is spread across 3 continents.

• Is there a way to combine IN and LIKE in MySQL?

  - by abeger

  I'm currently running a query like this: SELECT * FROM email WHERE email_address LIKE 'ajones@%' OR email_address LIKE 'bsmith@%' OR email_address LIKE 'cjohnson@%' The large number of OR's bothers me. Is there a way to condense this up with something akin to an IN operator, e.g.: SELECT * FROM email WHERE email_address LIKE ('ajones@%', 'bsmith@%', 'cjohnson@%') Or is this just wishful thinking?

• Drawing single pixel in Quartz

  - by wwrob

  I have an array of CGPoints, and I'd like to fill the whole screen with colours, the colour of each pixel depending on the total distance to each of the points in the array. The natural way to do this is to, for each pixel, compute the total distance, and turn that into a colour. Questions follow: 1) How can I colour a single pixel in Quartz? I've been thinking of making 1 by 1 rectangles. 2) Are there better, more efficient ways to achieve this effect?

• Determine precision and scale of particular number in Python

  - by jrdioko

  I have a variable in Python containing a floating point number (e.g. num = 24654.123), and I'd like to determine the number's precision and scale values (in the Oracle sense), so 123.45678 should give me (8,5), 12.76 should give me (4,2), etc. I was first thinking about using the string representation (via str or repr), but those fail for large numbers: >>> num = 1234567890.0987654321 >>> str(num) = 1234567890.1 >>> repr(num) = 1234567890.0987654

• So - vuvuzelas. any programming equivalents ?? [closed]

  - by jim

  Hi All, I'm sure we've all been exposed over the past few days to the delights of the vuvuzela (see http://news.bbc.co.uk/1/hi/magazine/8738604.stm). In an attempt to mask the waspish 'parp' from our living rooms, tv sound engineers are devising all sorts of filters to try and 'calm' the abhoration :). some tho say that it simply 'adds to the ambience' and that masking it out would be a denial of its 'additive' character. Now, on a programming related front, have you had to mask any extraneous 'noise' in a piece of work that you've picked up from someone else (or perhaps even your own!!)?? If so how 'inspired' was your remedy and how did you creatively 'reverse' it out once the noise had subsided and/or the pitch changed. :) tongue firmly in cheek... jim

• machine learning and code generator from strings

  - by BCS

  The problem: Given a set of hand categorized strings (or a set of ordered vectors of strings) generate a decision function to categorize more input. The question: are there any tools out there that will do that? I'm thinking of some kind of reasonably polished, download, install and go kind of things, as opposed to to some library or a brittle academic program.

• submitting data via email to websystem

  - by tnriverfish

  I'm working on a task system and I'd like to be able to submit a task to the system by emailing it to a particular address. I'm thinking I could set my user by the sender, the task subject by the subject and the task comments by the text of the email. Not sure the version of Exchange we have available if that matters but I'm running .net 3.5 and using C#. Any direction would be appreciated. Thanks, Charlie

• Haskell optimization of the following function

  - by me2

  Profiling of some code of mine showed that about 65% of the time I was running the following code. What it does is use the Data.Binary.Get monad to walk through a bytestring looking for the terminator. If it detects 0xff, it checks if the next byte is 0x00. If it is, it drops the 0x00 and continues. If it is not 0x00, then it drops both bytes and the resulting list of bytes is converted to a bytestring and returned. Any obvious ways to optimize this code? I can't see it. parseECS = f [] False where f acc ff = do b <- getWord8 if ff then if b == 0x00 then f (0xff:acc) False else return $ L.pack (reverse acc) else if b == 0xff then f acc True else f (b:acc) False

• Do tools exist wich automatically find copy-and-paste code?

  - by java.is.for.desktop

  Hello! Are there tools out there which could automatically find copy-and-paste code among a set of files? I was thinking of writing a script for this, which would just search for equal strings, but such script would find mostly irrelevant equalities. (Such as private final static ...).

• Where do you extend classes in your rails application?

  - by ro

  Just about to extend the Array class with the following extension: class Array def shuffle! size.downto(1) { |n| push delete_at(rand(n)) } self end end However, I was wondering where a good place to keep these sort of extensions. I was thinking environment.rb or putting in its own file in the initializers directory.

• is it a good idea to give background color or img to non transparent images?

  - by metal-gear-solid

  like img { background-color:color: color matched to the theme} or img { background-image:url (a very very tiny gif image with the text "image loading") } I'm thinking in the benefit of this when user access site on slow connection then background color will give clue about something is there which is diffrent than text content..

• Deserialize array values to .NET properties using DataContractJsonSerializer

  - by James Cadd

  I'm working with the DataContractJsonSerializer in Silverlight 4 and would like to deserialize the following JSON: { "collectionname":"Books", "collectionitems": [ ["12345-67890",201, "Book One"], ["09876-54321",45, "Book Two"] ] } Into classes like the following: class BookCollection { public string collectionname { get; set; } public List<Book> collectionitems { get; set; } } class Book { public string Id { get; set; } public int NumberOfPages { get; set; } public string Title { get; set; } } What's the proper place to extend DataContractJsonSerializer to map the unnamed first array element in "collectionitems" to the Id property of the Book class, the second element to the NumberOfPages property and the final element to Title? I don't have control over the JSON generation in this instance and would like the solution to work with the Silverlight subset of .NET. It would be great if the solution could perform the reverse for serialization as well.

• Does anyone know of a spell check library that underlines text?

  - by Icono123

  Does anyone know of a C# spell check library that would underline misspelled works in a windows form text box? In the past, I've used NetSpell and works great if users use the dialog box. I'm thinking I might be able to automatically call the spell check while text is being updated and underline the text. Anyone have any good ideas on what would be the best way to go about doing it?

• Can I view a list of public variables of some Adobe Air app or web flash file from another app?

  - by Parris

  I was thinking about creating making AIM pluggin that checks pandora one (desktop) or pandora website periodically to see what is currently playing and update a user's status. I suppose the main question is there a clever way to access a "public" variable from some open Adobe Air process? I KNOW this sounds like some crazy security flaw, but it may also be a feature. I am pretty sure javascript can potentially handle it. Thanks!

• Sort months ( with strings ) algorithm

  - by Oscar Reyes

  I have this months array: ["January", "March", "December" , "October" ] And I want to have it sorted like this: ["January", "March", "October", "December" ] I'm currently thinking in a "if/else" horrible cascade but I wonder if there is some other way to do this. The bad part is that I need to do this only with "string" ( that is, without using Date object or anything like that ) What would be a good approach?

• How to copy and paste text from one page to another page using jquery?

  - by ischnura

  I have to copy repeatedly data (contact info such as name, surname, telephone...) from form A (page 1 in domain x.com) to form B (page 2 in domain y.com) I have been thinking about creating a chrome extension with the help of jquery to copy the data from form A, and inject it form B... I have a feeling that this is not the best way to solve this problem... What do you think is the best way to copy and paste data from pages in different domains?

• Standard Workflow when working with JPA

  - by jschoen

  I am currently trying to wrap my head around working with JPA. I can't help but feel like I am missing something or doing it the wrong way. It just seems forced so far. What I think I know so far is that their are couple of ways to work with JPA and tools to support this. You can do everything in Java using annotations, and let JPA (whatever implementation you decide to use) create your schema and update it when changes are made. You can use a tool to reverse engineer you database and generate the entity classes for you. When the schema is updated you have to regenerate these classes, or manually update them. There seems to be drawbacks to both, and benefits to both (as with all things). My question is in an ideal situation what is the standard workflow with JPA? Most schemas will require updates during the maintenance phase and especially during the development phase, so how is this handled?
