• Import Data from Excel Spreadsheet or CVS into MySQL

  - by Kelly Roper

  I have a spreadsheet which really has only one complicated table. I basically convert the spreadsheet to a cvs and use a groovy script to generate the INSERT scripts. However, I cannot do this with a table that has 28 fields with data within some of the fields on the spreadsheet that make importing into the CVS even more complicated. So the fields in the new CVS are not differentiated properly or my script has not accounted for it. Does anyone have any suggestions on a better approach to do this? Thanks.

• AsyncTask won't stop even when the activity has destroyed

  - by Raja

  Hi all, I have an AsyncTask object which starts executing when the activity is created and does stuff in the background (downloads upto 100 images). Everything works fine but there is this peculiar behavior which i'm not able to understand. For eg: when the android screen's orientation changes then the activity is destroyed and created again. So I override the onRetainNonConfigurationInstance() method and save all the downloaded data executed in the AsyncTask. My purpose of doing this is to not have AsyncTask run each time activity is destroyed-created during orientation changes, but as i can see in my logs the previous AsynTask is still executing. (The data is saved correctly though) I even tried to cancel the AsynTask in the onDestroy() method of the activity but the logs still show AsynTask as running. This is really strange behavior and would really be thankful if someone can tell me the correct procedure to stop/cancel the AsynTask. Thanks

• Random numbers from binomial distribution

  - by Sarah

  I need to generate quickly lots of random numbers from binomial distributions for dramatically different trial sizes (most, however, will be small). I was hoping not to have to code an algorithm by hand (see, e.g., this related discussion from November), because I'm a novice programmer and don't like reinventing wheels. It appears Boost does not supply a generator for binomially distributed variates, but TR1 and GSL do. Is there a good reason to choose one over the other, or is it better that I write something customized to my situation? I don't know if this makes sense, but I'll alternate between generating numbers from uniform distributions and binomial distributions throughout the program, and I'd like for them to share the same seed and to minimize overhead. I'd love some advice or examples for what I should be considering.

• Saving core data in a thread, how to ensure its done writing before quitting?

  - by Shizam

  So I'm saving small images to core data which take a really short amount of time to save, like .2 seconds but I'm doing it while the user is flipping through a scroll view so in order to improve responsiveness I'm moving the saving to a thread. This works great, everything gets saved and the app is responsive. However, there is one thing in the core-data + multithreading doco that worries me: "In Cocoa, only the main thread is not-detached. If you need to save on other threads, you must write additional code such that the main thread prevents the application from quitting until all the save operation is complete." Ok, how do you do that? It only needs to last ~ .2 seconds and its rarely going to happen since the chance of the app quitting as something is saving is very low. How do I run something on the main thread that'll prevent the app from quitting AND not block the gui? Thanks

• iPhone App takes up too much memory

  - by Stephen Furlani

  Ok, so here's my problem. My iPhone app is 1.2MB on disk. Granted I have a bunch of Images for the GUI buttons and backgrounds, etc. In-memory, my app takes up a whopping 15MB! That means if I then take a picture with the camera, 8MB default, it gives a memory warning (several) even before the picker calls its delegate! How can I tell what is grabbing so much memory, and how to remove it? I've removed all of my debugging symbols and added [-Os], but it still takes up a huge amount of memory! Also, (how) can I change the default resolution of the camera?

• C++0x optimizing compiler quality

  - by aaa

  hello. I do some heavy numbercrunching and for me floating-point performance is very important. I like performance of Intel compiler very much and quite content with quality of assembly it produces. I am thinking at some point to try C++0x mainly for sugar parts, like auto, initializer list, etc, but also lambdas. at this point I use those features in regular C++ by the means of boost. How good of assembly code do compilers C++0x generate? specifically Intel and gcc compilers. Do they produce SSE code? is performance comparable to C++? are there any benchmarks? My Google search did not reveal much. Thank you.

• DataGridView that always has one row selected

  - by Dan Neely

  I'm using a DGV to show a list of images with text captions as a picklist. Their must always be a one and only one selection made in the list. I can't find a way to prevent the user from clearing the selection with a control-click on the selected row. Is there a property in the designer I'm missing that could do this? If I have to override the behavior in the mouse click events are there other ways the user could clear the current selection that need covered as well? Is there a third approach I could take that's less cumbersome than my second idea?

• Creating DB views in Ruby on Rails

  - by Zigu

  Hey guys, I'm building a "reports" functionality to a project. 3 roles here: 1) Volunteers (they report what hours they volunteered) 2) Supervisors (they look at the reported stuff, note: one supervisor can view all projects) 3) Projects (Represents a work project that some collection of volunteers work on) To explain what it does: A report will be specified by the supervisor to generate based on a query of what he needs. These could be plausible reports: 1) The total number of volunteers, and the total amount of volunteer hours on this project 2) All the volunteer's names and emails associated with a project 3) The number of active projects vs. the total number of projects I was thinking maybe that creating a view in rails and storing the name of that view so Rails will just check the view whenever a supervisor wants to pull up the "report". Is a view really the answer or is it better to just save a query? Can Rails do this or is there an even better or more simple way of achieving this functionality? Cheers, -Jeremiah Tantongco

• memory usage in iOS

  - by varun

  My app has a simple UI interface having simple buttons, date picker, picker view, table view, action sheet, toolbar, alert boxes etc. No images, no network access. Just plain simple UI. It accesses SQLite database a lot. ARC option is enabled. I have many questions to ask: In .h files, I am defining IBOutlets like @property(nonatomic, retain) IBOutlet UIButton *bt; Where do i need to do bt=nil? in didReceiveMemoryWarning or viewDidLoad Live Bytes in Instruments tool is 4-5MB. Is it enough or I need to reduce memory usage? If so, how can I do so? Please mention few important points. Also, what all need to be added to the following methods? applicationDidReceiveMemoryWarning UIApplicationDidReceiveMemoryWarningNotification

• Attach an HREF and a class to an img link generated by the PhotoSlider script?

  - by Frank Bailey

  Hi folks, I'm using the very nice PhotoSlider script from http://opiefoto.com/articles/photoslider to create a slide show of images for one of my clients. This script replaces a previous hand-coded Javascript solution that allowed for the large image to be clicked resulting in a lightbox modal popup showing the full-size version of the clicked picture. Of course the client insists that this functionality remain intact, but the HTML code for the large image is generated on-the-fly by the PhotoSlider script itself. This means I'll need to modify the script slightly to attach a class ("lightbox") and an href (or just a click event, whichever makes more sense), but I'm not quite sure how best to accomplish this. I figure the event and class will have to be attached each time a thumbnail is clicked, but if this isn't the best way to do it any advice will be appreciated. The script is implemented into my page as can be seen here, without the click or class. I'd really appreciate any assistance stackoverflowites can offer. Thanks in advance!

• What action is my Symfony/Doctrine generated form actually going to?

  - by Arms

  In my Symfony 1.4 project I am using the doctrine:generate-admin task to create the modules that compose my backend system. One such module is "journeys". When I view the source of the "journeys/new" page (which displays the form to create a new journey entity) the action of the form is simply "journeys" (I expected it to be "journeys/create"). The "journeys" route on its own would call the executeIndex method - however I put a log call in there and upon form submission, the log is not made. So this leads me to believe that executeIndex is NOT being called, and another piece of code is being fired upon form submission that then (depending on a hidden input in the form) calls either executeCreate() or executeUpdate(). Problem is, I don't know where that would be happening. Any insight would be much appreciated. I don't if this is relevant, but here is the routing definition for the journeys module journey: class: sfDoctrineRouteCollection options: model: journey module: journeys prefix_path: /journeys column: id with_wildcard_routes: true Thanks!

• display text when image on-click/hide text when different image click

  - by Jonah1289

  Hi I have created the following effects on the images seen here http://techavid.com/design/test3.html . You see when you hover and then click on each image, they go from grey to color. When you click on one - the others go grey and the one clicked remains color. That's cool, but now I need the text 1st: Sun for example to display and hide along with its graphic button. The word "Sun," is a link that needs to link out to a URL so it has to be separated from the image effect code. What jquery or javascript code do I need to do this? thanks, jonah p.s. How do i properly post the code I have now. I tried to paste code in "enter code here," but received errors - thnx

• Errors when using a Ruby On Rails scaffold with a data type of interger

  - by bublebboy

  I am learning Ruby On Rails. I am on a shared hosting with Ruby version 1.8.1 and Rails version 2.3.10. I am working my way through a tutorial at http://railstutorial.org/chapters/a-demo-app?version=2.3#top and at one point in the tutorial it has me run: script/generate scaffold Micropost content:string user_id:interger The tutorial is using the default database, SQLite3. The command works and I use rake db:migrate to create the database. I can view the page listing the microposts (which is empty), but when I try to add a micropost (microposts/new) I get an error undefined method `user_id' for #<Micropost:0x7f710e4988e8> After doing some testing on my own it seems I experience the problem by using the data type of interger. While I understand that using a scaffold is not the best way of building a ruby on rails, I'm just beginning and would still like to know why I am experiencing this problem to help me better understand how rails works.

• PHP Check if <ul> has ended IF it exists

  - by Krewe

  I have my blog generate a preview by taking the first 300 characters and cut off the last whole word. My problem is, when I have a list near the top of the blog it is sometimes included in the preview, however the end list tag usually never is. So how can I check the $preview variable for a starting list tag, and if it is found, check for an ending tag and if it's not there add one. All the code for my preview. $preview = wordwrap($content, 300); $preview = explode("\n", $preview); $preview = $preview[0] . "...";

• Cakephp: Designpattern for creation of models in hasMany relationship

  - by Chris

  I have two Models: Car and Passenger. Car hasMany Passenger Passenger belongsTo Car I managed to create add functionailty for each model and managed to resolve the hasMany relationship between them. Now I'm trying to create a addCar function and view that allows the user to create a new car and automatically generate Passengers. I thought of something like this The view asks the user enter the car information The view has some field that allows to temporarly add new passengers and remove remove them When the user saves the new car, the entities for the passengers are created, the entity for the car is created and the passengers are linked to the car. If the user decides to cacnel everything, the DB remains unchanged. Now my question is: What is the best way to do this? Is there a pattern / tutorial to follow for such a entity and associated subentity creation? To clarify: The passengers associated with each car do not exist prior to the existence of the car.

• jquery background image fade

  - by Nick

  I am using jQuery to load ina background image that fills the page width / height. I have the following in the Head: $(document).ready(function() { $('body').css({ 'background-image' : 'url({HTML_BASE}images/backgrounds/randoms/{BACK_IMG})', 'background-repeat' : 'no-repeat', 'background-position' : 'center top', 'background-attachment': 'fixed', 'background-size': '100% 100%', }); $('#home-promo').innerfade({ speed: 'slow', timeout: 5000, type: 'sequence', containerheight: 'auto' }); $('.model-search').innerfade({ speed: 'slow', timeout: 5000, type: 'sequence', containerheight: '393' }); }); This works fine and can be seen at http://projects.snowshtechnologies.com/golden_dragon/home/ I want the BG image to fade in from the black background colour. I have looked at a few other threads on Stack that suggest its not possible as a body element defined in css, but in this scenario the BG image is being loaded in by jQuery. How would I go about adding a fade in to this code to bring the image in with a nice fadein?

• UIButton setBackgroundImage consumes doesn't release memory?

  - by just_another_coder

  My UIButton has it's background image set like this: [myImageButton setBackgroundImage:[UIImage imageNamed:myImageName] forState:UIControlStateNormal]; myImageButton is a retained property of the class, and is setup with IB. No where else is it accessed in the app. myImageName is simply an NSString with a filename like @"myImage_number_1.png" I am loading large images, 1024 x 1024 in size. When the view is shown, it changes the image with the above statement, then available memory decreases. After I see the view about 7-9 different times, the app crashes with a memory warning. I thought the method would free up the loaded image. The view itself is only instantiated and allocated one time, so it's not in the retain/release cycle if the view controller. Is there something about this setBackgroundImage I don't know that causes it to not release memory?

• Can I use part of MD5 hash for data identification?

  - by sharptooth

  I use MD5 hash for identifying files with unknown origin. No attacker here, so I don't care that MD5 has been broken and one can intendedly generate collisions. My problem is I need to provide logging so that different problems are diagnosed easier. If I log every hash as a hex string that's too long, inconvenient and looks ugly, so I'd like to shorten the hash string. Now I know that just taking a small part of a GUID is a very bad idea - GUIDs are designed to be unique, but part of them are not. Is the same true for MD5 - can I take say first 4 bytes of MD5 and assume that I only get collision probability higher due to the reduced number of bytes compared to the original hash?

• Ruby on Rails - Calendar Display

  - by user335725

  We want to create a calendar view in a room scheduling application. The outcome we want is to have hours open (variable depending on day) across the top of the grid and the names of the rooms down the left side of the grid. The body would be populated with bookings for that day. The visual we're seeking is similar to the "Weekly Builder" plugin for Rails (http://dmix.ca/2009/06/weeklybuilder-a-weekly-calendar-plugin-for-rails/). We've tried using CSS to create variably-sized images, but this isn't working out. Are there any plugins available or other ways anyone can think of to accomplish this kind of visual? Thanks

• Best way to move a bunch of SQL Server 2005 tables to another Server?

  - by Mikecancook

  I've been looking for a way to move a bunch of tables, more than 40, to another server with all the data in them. I've looked around for scripts to generate inserts but so far I'd have to run them once for every table, then copy all the scripts over and then run them on the server. Seems like there is a better way. --Update-- My strategy for doing this may have been for naught. The end script, using MS SQL Server Publishing Wizard and Red Gates SQL Data Compare (excellent tool, btw) results in a file over 1GB. This makes my system plead for mercy and I'm not willing to risk crashing a clients server just opening the file to run it. I may have to rethink this whole thing and break down to just individual per table scripts. I'm not looking forward to that.

All i am doing is updating an attribute on the div and updating the html. this shouldn't fire a click event?

• Core Data No Longer Updating Sqlite Schema

  - by nefsu

  I am using core data for my app and I never had any problems adding or removing columns until recently. But now even if I make changes to my xcdatamodel and generate new and updated entity h/m files, sqlite doesn't seem to be picking up the changes. I actually went over to the documents folder and inspected the create statement for the relevant tables in sqlite3 and I was able to confirm that the columns I added were missing. I removed and redeployed the app several times to no avail. Is it possible to do something to the app to make it disregard any schema changes being made through xcdatamodel? I guess another thing I should mention is I recently started putting my entire projects folder in CVS so I wonder if something got messed up in the checkin and check out process.
