  • Evenly distribute items on the screen

    - by abolotnov
    I am trying to solve this little puzzle (the algorithm): I have N image icons and I want to distribute them evenly on users screen. Say, I put them in a table. If there is one image, there will be one cell in a table. If two - one row with two columns, if three - one row and three columns, if four - two rows, two columns... and so on until row space is gone and since then the table should only grow in columns without adding extra rows. I'm trying to figure an algorithm for this and perhaps this is something that has a solution already somewhere? My attempt is so far something like this: obtain_max_rows() obtain_visible_columns() if (number_of_pictures > max_rows*max_columns) { columns = roundup(number_of_pictures/max_rows) for(max_rows){generate row;for columns{generate column}} } else { **here comes to trouble...** } This logic is bit silly though - it somehow needs to think cases where there are 12 pictures on first screen and 2 on the other trying to balance it say 8/6 or somehow like that.

  • Bitwise Shifting in C

    - by user313943
    I've recently decided to undertake an SMS project for sending and receiving SMS though a mobile. The data is sent in PDU format - I am required to change ASCII characters to 7 bit GSM alphabet characters. To do this I've come across several examples, such as http://www.dreamfabric.com/sms/hello.html This example shows Rightmost bits of the second septet, being inserted into the first septect, to create an octect. Bitwise shifts do not cause this to happen, as will insert to the left, and << to the right. As I understand it, I need some kind of bitwise rotate to create this - can anyone tell me how to move bits from the right handside and insert them on the left? Thanks,

  • Accidentally deleted /opt/local/bin without backup. Any help?

    - by Aaron
    Hi all, I'm on a Mac OS X 10.5.8 I was recently uninstalling mysql5 from /opt/local/bin. I typed: rm -rf /opt/local/bin mysql* instead of rm -rf /opt/local/bin/mysql* This deleted my entire /opt/local/bin directory which puts me in a bit of a bind. Is there any way to recover these files? If not, I have a friend that is using a similar set of programs, would it be possible to use the contents of his folder? If I end up needing to re-install everything in this folder, what is the best way to go about doing this? Thanks in advance!

  • Regular Expression find a phrase not inside an HTML tag

    - by James Buckingham
    Hi there, I'm struggling a bit with this regular expression and wondered if anyone was about to help me please? What I need to do is isolate the 1st phrase inside a string which is NOT inside an HTML tag. So the examples I have at the moment are: This is some test text about ITS for the ITS department. Also worth mentioning ABS as well I guess.ITS, ... and ... This is some ITS test text about ITS for the ITS department. Also worth mentioning ABS as well I guess So in the first example I want it to ignore the wrapped ITS and give me the ITS at the end of the 1st sentence. In the second example I want it to return the ITS at the start of the 2nd sentence. The aim is to replace these with my own custom wrapped acronym tags in a ColdFusion application I'm writing. Thanks a lot, James

  • .NET --- Textbox control - wait till user is done typing

    - by Cj Anderson
    Greetings all, Is there a built in way to know when a user is done typing into a textbox? (Before hitting tab, Or moving the mouse) I have a database query that occurs on the textchanged event and everything works perfectly. However, I noticed that there is a bit of lag of course because if a user is quickly typing into the textbox the program is busy doing a query for each character. So what I was hoping for was a way to see if the user has finished typing. So if they type "a" and stop then an event fires. However, if they type "all the way" the event fires after the y keyup. I have some ideas floating around my head but I'm sure they aren't the most efficient. Like measuring the time since the last textchange event and if it was than a certain value then it would proceed to run the rest of my procedures. let me know what you think. Language: VB.NET Framework: .Net 2.0 --Edited to clarify "done typing"

  • htaccess, remove text from url

    - by Keiron Lowe
    Here is the email from the client explaining what he is trying to do, we have spent hours trying to sort out this problem but cannot find a solution that works. I am trying to correct a problem with my blog and google “not found” URLs. I thought it might be very simple to correct (!ha!) This is my line of code; RewriteCond %{THE_REQUEST} ^www.uk-domestic-cleaning.com/wpblog/tag/?(.*)/HomeMaid%20Domestic%20Cleaning$ RewriteRule ^wpblog\/tag\/?(.*)\/HomeMaid%20Domestic%20Cleaning$ "http\:\/\/www\.uk\-domestic\-cleaning\.com\/wpblog\/tag\/$1" [R=301,L] What I am trying to do is any request to */wplog/tag/ “anything here”/HomeMaid Domestic Cleaning To strip the “HomeMaid Domestic Cleaning” bit off the end, but leave the rest of the request intact, which will then be a valid request. Any idea's guys?

  • SQL server virtual memory usage and perofrmance

    - by user365035
    Hello, I have a very large DB used mostly for analytics. The performance overall is very sluggish. I just noticed that when running the query below, the amount of virtual memory used greatly exceed the amount of physical memory available. Currently, phsycial memory is 10GB (10238 bytes) where as the virtual memory returns significantly more 8388607 bytes. That seems really wrong, but I'm at a bit of a loss on how to proceed. USE [master]; GO select cpu_count , hyperthread_ratio , physical_memory_in_bytes / 1048576 as 'mem_MB' , virtual_memory_in_bytes / 1048576 as 'virtual_mem_MB' , max_workers_count , os_error_mode , os_priority_class from sys.dm_os_sys_info

  • Only compiles as an array of pointers, not array of arrays

    - by Dustin
    Suppose I define two arrays, each of which have 2 elements (for theoretical purposes): char const *arr1[] = { "i", "j" }; char const *arr2[] = { "m", "n" }; Is there a way to define a multidimensional array that contains these two arrays as elements? I was thinking of something like the following, but my compiler displays warnings about incompatible types: char const *combine[][2] = { arr1, arr2 }; The only way it would compile was to make the compiler treat the arrays as pointers: char const *const *combine[] = { arr1, arr2 }; Is that really the only way to do it or can I preserve the type somehow (in C++, the runtime type information would know it is an array) and treat combine as a multidimensional array? I realise it works because an array name is a const pointer, but I'm just wondering if there is a way to do what I'm asking in standard C/C++ rather than relying on compiler extensions. Perhaps I've gotten a bit too used to Python's lists where I could just throw anything in them...

  • Safari javascript cookie issue

    - by Aaron Moodie
    I've hit a bit of a weird issue in Safari in regards to setting a js cookie. The cookie itself is just a rgb colour value, which gets set using .click(), and is working fine in Chrome and Firefox, yet in Safari the value of the cookie is incomplete, showing up as rgb(193 instead of rgb(193, 184, 76) as the other browsers do. The jQuery function I'm using to set the cookie is: $('.project_link a').click(function() { var link_colour = $(this).css("color"); document.cookie = "colour="+link_colour+";expires=;path=/"; });

  • iphone tabbar with custom buttons and scrollvie

    - by chunjai
    i'm trying to get a tab bar effect not unlike russel quinn's 'creative review' app. the tabbar swipes across, which i have figured out, but the tabbar style itself is unlike anything i've seen on the iphone (though it looks so simple!). it has square buttons with a space between, and each button has a select/active/inactive state. i'm having a hard time seeing how this can be tabbar, but i don't know any other way. can someone explain this? here's the example :: http://bit.ly/c8CeBC. any help is appreciated.

  • How to check code is compatible with Windows 7

    - by Julen
    Hello, We are developing using Visual C# 2008 Express a program based on WPF under Windows XP machines (32 bits). The thing is that we have tried to run the program in two Windows 7 machines, one is 32 bits Windows 7 and the other is 64 bits Windows 7. Under Windows XP everything is fine. In Windows 7 machine, it launches in the 32 bits version altough there is an error when running one functionality (it does not happen in XP). In W7 64 bits it even does not launch. Is this normal? Is not possible to run 32 bit programs under W7 64-bits,even if they execute slower?? How can we check the code is compatible with Windows 7? Thank you very much in advance. Julen.

  • long processes php

    - by significance
    hi, i need to run a really long php script (four and half, five hours). the script sometimes runs successfully, but sometimes gets killed inexplicably (poss something to do with the shared hosting??). i think that the solution maybe to run the script is smaller chunks. in order to do this i have written a script that stores it's status & position in an xml file, and executes one chunk of the script, before moving the position on. i am having problems hooking up the last bit of the script, which should end the current process & re-execute the script. or maybe i am barking up the wrong tree completely! i have read through what i can find on SO and elsewhere but i'm still none the wiser :( please help!!! dan

  • UITableView with Core Data and fetchedResultsController - don't want to call it at start up

    - by zebulon
    Hi all, I started with the Navigation-based application. I have a UITableView that shows the content fetched from CoreData - using the - (NSFetchedResultsController *)fetchedResultsController from the template. The thing is that I don't want to fill the TableView with the results at the start-up, instead I want to fill the TableView with the results from a search. In my app I have an UITextField, where the user can type a string. And from that string, using predicate, I want to fill the UITableView with the results. In other words, at start-up, the UITableView should be empty and later filled with the search-results. Does anyone have an idea on how to accomplish this? Thanks in advance! EDIT: Solved it by moving out if (![fetchedResultsController_ performFetch:&error]) { and calling it later. I feel a bit stupid ;)

  • How to use locks/synchronization here

    - by MasterGberry
    I have this code block here and i need to make sure the rankedPlayersWaitingForMatch is synchronized between threads properly. I was going to use synchronize but that i don't think will work here because of the variable being used in the if statement. I read online about final Lock lock = new ReentrantLock(); but I am a bit confused on how to use it in this case properly with the try/finally block. Can I get a quick example? Thanks // start synchronization if (rankedPlayersWaitingForMatch.get(rankedType).size() >= 2) { Player player1 = rankedPlayersWaitingForMatch.get(rankedType).remove(); Player player2 = rankedPlayersWaitingForMatch.get(rankedType).remove(); // end synchronization // ... I don't want this all to be synchronized, just after the first 2 remove() } else { // end synchronization // ... }

  • Move a sequential set of commits from one (local) branch to another

    - by jpswain09
    Is there a way to move a sequential set of commits from one (local) branch to another? I have searched quite a bit and still haven't found a clear answer for what I want to do. For example, say I have this: master A---B---C \ feature-1 M---N---O---P---R---Q And I have decided that the last 3 commits would be better off like this: master A---B---C \ feature-1 M---N---O \ f1-crazy-idea P---R---Q I know I can do this, and it does work: $ git log --graph --pretty=oneline (copying down sha-1 ID's of P, R, Q) $ git checkout feature-1 $ git reset --hard HEAD^^^ $ git checkout -b f1-crazy-idea $ git cherry-pick <P sha1> $ git cherry-pick <R sha1> $ git cherry-pick <Q sha1> I was hoping that instead there would be a more concise way to do this, possibly with git rebase, although I haven't had much luck. Any insight would be greatly appreciated. Thanks, Jamie

  • Is autoload thread-safe in Ruby 1.9?

    - by SFEley
    It seems to me that the Ruby community has been freaking out a little about autoload since this famous thread, discouraging its use for thread safety reasons. Does anyone know if this is no longer an issue in Ruby 1.9.1 or 1.9.2? I've seen a bit of talk about wrapping requires in mutexes and such, but the 1.9 changelogs (or at least as much as I've been able to find) don't seem to address this particular question. I'd like to know if I can reasonably start autoloading in 1.9-only libraries without any reasonable grief. Thanks in advance for any insights.

  • When not to use a Drupal node?

    - by stotastic
    I've recently created a very simple CRUD table where the user stores some data. For the data, I created a custom node. The functionality works great for creating, editing, and deleting data in the CRUD table using the basic node functionality (I'm actually amazed how fast and easy it was to program the basic functionality with proper access controls using only a tiny bit of code).... Since the data isn't meant to be treated the same way as 'content' such as a blog post (no title, no body, no commments, no revisions, shouldn't show up on ?q=node page, no previews, no teasers, etc)... I find that I'm spending most of my time 'turning off' and modifying the stuff that drupal does automatically for nodes. I know its a matter of taste, but where should one draw the line on what should be treated as a node and what shouldn't? In other words, would it be better to program this stuff from scratch without using nodes?

  • Executing commands on a Unix box from ASP .NET

    - by StefanE
    I'm in process to create a few utilities for my team to make life a bit easier working with our Unix boxes(most of them Solaris based). For example I'm creating a ASP .NET page to display the output of TOP. Also plan to be able to restart processes with the KILL -15 command. Now I wonder if there is any nice modules out the do the work for me or am I better off just going ahead with my own SSH communication? It would of course make sense building the app on the unix box directly but I'm not able to do this.

  • Issue with Java join() method.

    - by gmunk
    First of all here are some code snippets: http://pastebin.com/9ZCwekXs http://pastebin.com/TtLLXPYP I'm trying to animate some images. The thing is that I want the main thread to wait for the animation thread to finish and then to continue. I searched around, read a little bit and decided to use the join() method. It perfectly waits for the thread to finish but I doesn't animate correctly. The repaint() method gets called 2 times instead of nine. I think maybe the problem is because I used singletons. Here is the singleton implementation. http://pastebin.com/bA3qLZJE

  • Documenting a policy based design

    - by academicRobot
    I'm re-working some prototype code into a policy based design in C++, and I'm wondering what the best practice is for documenting the design. My current plan is to document: Policy hierarchy Overview of each policy Description of each type/value/function in each policy I was thinking of putting this into a doxygen module, but this looks like it will be a bit awkward since formatting will have to be done by hand without code to base the doc on (that is, documenting the policies rather than the implementation of the policies). So my questions are: Are there other aspects of the design that should be documented? Are there any tricks to doing this efficiently in doxygen? Is there a tool other than doxygen thats better suited to this? What are some examples of well documented policy based design? This is my first serious attempt at policy based design. I think I have a working grasp of the principles, but whatever naivety I expose in this question is fair game for an answer too.

  • Rails: How to produce 404 or redirect upon undesired url exploitation?

    - by Baby Diego
    I want to hide the urls for editing users and their profiles behind safer and meaningful urls. For instance, I want /user/13/edit to be /settings/account and /user/13/profile/edit to be /settings/profile. I managed to achieve that, but for that I had to load the user information from the current_user bit from the session. Like so: # users_controller def edit @user = current_user end # profiles_controller def edit @user = current_user @profile = @user.profile end But now, since I can't compare @user.id from the params with the current_user in the session, how can I stop the old urls (/user/13/edit and /user/13/profile/edit) from being exploitable? They always load the forms for the current user, so there's no harm done, but I'd be more comfortable if they just produced a 404 error or something. Thanks in advance.

  • .NET & ASP vs PHP

    - by gargantaun
    Earlier today I asked wether it would be a good idea to develop websites using C#. Most of the answers pointed towards .NET and ASP. Currently I develop with PHP. I've dabbled with Python and RoR but I always come back to PHP. This is the first time I've looked at .NET and ASP. A bucket load of Google searches later I'm not really seeing much support for ASP online but then it all seems a bit Biased towards PHP/Apache/MySQL. It looks like there's a fair amount of .NET and ASP folk around here so I figured it's worth a shot asking for their input in attempt to try and address the balance in my own head. It can't all be bad. What advantages are there to .NET and ASP over PHP?

  • How do I indicate that a class doesn't support certain operators?

    - by romeovs
    I'm writing a class that represents an ordinal scale, but has no logical zero-point (eg time). This scale should permit addition and substraction (operator+, operator+=, ...) but not multiplication. Yet, I always felt it to be a good practice that when one overloads one operator of a certain group (in this case the math operators), one should also overload all the others that belong to that group. In this case that would mean I should need to overload the multiplication and division operators also, because if a user can use A+B he would probable expect to be able the other operators. Is there a method that I can use to throw an error for this at compiler time? The easiest method would be just no to overload the operators operator*, ... yet it would seem appropriate to add a bit more explaination than operator* is not know for class "time". Or is this something that I really should not care about (RTFM user)?

  • Problems with .net and toolbar, menu & status bar rendermode (blue) and standard form (grey)

    - by Andrew White
    Hiya, I'm a bit of a newbie to .NET so please ignore my ignorance. If you look at the above image (a complete prototype, ignore black bits :)) you will see lovely menus, toolbars & statusbars all using windows XP render mode and in a funky blue. Look at the form, labels, checkboxes and other buttons and you see horrible old school windows grey. These components don't have a render mode. My question: is there any way to show everything in XP style or do I have to chose new components? Thx. A.

  • OOWrite is to LaTeX as OODraw is to?

    - by grimborg
    I'm looking for a tool to nicely generate single-page PDFs. My needs are: Able to put a PDF/EPS/... as a background Absolute positioning Able to define tables, lists Able to rotate blocks Reasonably easy syntax (will be used to automatically generate many similar looking documents) Easily usable from Python Free or very cheap In essence I'm looking for the tool X that is to OODraw/CorelDraw/... as LaTeX is to OOWrite/MS Word. I've looked at webkit2pdf and a headless OODraw, but both seem a bit of an overkill. XML-FO has some limitations such as not being able to predict how many pages your document spans. Reportlab is pricey. Any ideas? Thanks!
