MySQL some columns Distinct

- by Adam

I have the following query that works well. SELECT DISTINCT city,region1,region2 from static_geo_world where country='AU' AND (city LIKE '%geel%' OR region1 LIKE '%geel%' OR region2 LIKE '%geel%' OR region3 LIKE '%geel%' OR zip LIKE 'geel%') ORDER BY city; I need to also extract a column named 'id' but this messes up the DISTINCT as each ID is different. How can I get the same UNIQUE set of records as above but also get the 'id' for each record? Note: sometimes I can return a few thousand records so a query for each record isn't possible. Any ideas would be very welcome...

Adding the scrollview created by photoscroller to a subview

- by wierddemon

I'm trying to modify Apple's PhotoScroller example to make the scrollview that is created into a subview instead of it being a view that takes up the entire screen. Any ideas on how this can be accomplished? - (void)loadView { // Step 1: make the outer paging scroll view CGRect pagingScrollViewFrame = [self frameForPagingScrollView]; pagingScrollView = [[UIScrollView alloc] initWithFrame:pagingScrollViewFrame]; pagingScrollView.pagingEnabled = YES; pagingScrollView.backgroundColor = [UIColor blackColor]; pagingScrollView.showsVerticalScrollIndicator = NO; pagingScrollView.showsHorizontalScrollIndicator = NO; pagingScrollView.contentSize = [self contentSizeForPagingScrollView]; pagingScrollView.delegate = self; // When I do this it fails [self.view addSubview:pagingScrollView]; // Step 2: prepare to tile content recycledPages = [[NSMutableSet alloc] init]; visiblePages = [[NSMutableSet alloc] init]; [self tilePages]; }

Change URL of a saved HTML file

- by Paul Camilleri

I am new to HTML so this question might sound a bit lame. Anyways I have a saved webpage on my desktop that when i open it in google chrome i want it to show a specific URL instead of its current location. Any ideas how i might get this to work? I tried using the history.pushState but i have no idea why it is not working. I created a simple page for now to test it: <html> <head> <script> function setURL() { history.pushState("Test","page2", "www.test.com"); } </script> </head> <body> <button type="button" onclick="setURL()">Set Url</button> </body> </html> Any help would be greatly appreciated. Thank you

My company is a Rackspace Cloud client (provided to us for free) and I'm trying to find some way to set up version control

- by Nick S.

As the title says, my (small) business is provided a free Rackspace Cloud client account. We receive a decent amount of traffic but I haven't been able to put together a business case to move to our own server yet. However, we are developing some complex apps and I'm frustrated with not having the ability to even ssh into the remote server. Ultimately, I'd like to set up some sort of version control (at this point, I'll take anything, git or otherwise). I have control over databases, can FTP, set up cron jobs, and perform a few other basic functions. I can't think of any way to set up git or something similar without ssh access. A thought went through my mind that maybe some sort of PHP version control exists that I might be able to set up, but I haven't had any luck finding it yet. Do you guys have any ideas, thoughts, or advice?

I have a tab delimeted file that I want to convert into a mysql table

- by user320835

I have a tab delimeted file that I want to convert into a mysql table. there are 25 tab delimeted fields in the text file. I can get the values in when I construct the SQL statement word by word and get each value individually stated in the VALUES part but when I try to get the list as a whole it does not work. Here is the code. I couldn't figure it out. Any ideas? lines=open(path, "r").readlines() for line in lines[1:]: linex=line.strip().split("\t") linex.insert(0,'sometextindex') try: cursor.execute('INSERT INTO variants VALUES(%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s)',linex) except: print 'line number=',a,linex

Rails valiation among a three model relationship

- by Andrew

I'm working on a three model relationship with one aspect that I'm not sure how to approach. Here's the basic relationship: class Taxonomy has_many :terms # attribute: `inclusive`, default => false end class Term belongs_to :taxonomy has_and_belongs_to_many :photos end class Photo has_and_belongs_to_many :terms end This is pretty straightforward stuff except for one thing: A Taxonomy can be either 'Inclusive' or 'Exclusive'. Exclusive means the terms are mutually exclusive, Inclusive means they're not. So, if a Taxonomy is exclusive ie. taxonomy.inclusive = false, then there can only be one term from that taxonomy attached to a given photo. Now, I can handle this on the client-side without a problem, but I am not quite sure how to set up a validation on Photos (or somewhere else) that says basically: "validate that no more than one term from an exclusive taxonomy is associated with this record." Any ideas on how to do that?

How expensive is a call to java.util.HashMap.keySet()?

- by fx42

I implemented a sparse matrix as List<Map<Integer,Double>>. To get all entries of row i I call list.get(i).keySet(). How expensive is this call? I also used the trove library for an alternative implementation as List<TIntDoubleHashMap>. What's the cost of calling list.get(i).keys(), here? Do you have any further ideas of how to implement an efficient sparse matrix? Or can you provide a list of existing implementations in java?

Prioritize SQL WHERE clause

- by JaTochNietDan

Basically I want to do this: SELECT * FROM `table` WHERE x = 'hello' OR x = 'bye' LIMIT 1'; I want it to return 1 value, but to prioritize results from the 1st where clause. So if there exists a row where column x's value is "hello", it will not return the result from the 'bye' value. If the "hello" value doesn't exist though, it will return the result from the 'bye' value. Can't figure out a way to do it even though it seems fairly trivial. Any ideas?

jQuery variable iteration with .each()

- by user1143357

My code needs to capture the 'src' of an image in a variable. It then needs to insert this variable into a 'href' tag on a link which surrounds the image. My code is as follows: $('.fancybox-image-li img').each(function(test) { var test = $(this).attr("src"); $('.fancybox-image-link').attr('href', ''+test+''); }); Unfortunately what seems to be happening is the 'test' var is only getting the attribute of the last img and then inserting this into all the 'href' attributes. Any ideas how I can get the variable to change per image. Cheers!

Solr authentication possible? (or apache port authentication would also work)

- by Camran

Currently anybody can access the solr admin page by going to my_ip:8983/solr I can't have it like that, so how can I make it prompt for password or something? I have setup my servers apache2.conf file to prompt for password whenever my site is accessed by www.mydomain.com. But when using another port, the "require password" wont show up. Any ideas how to secure this? Don't point me to the SolrSecurity wiki because it's simply too outdated. I have tried it without luck. Thanks

C++ - Implementing my own stream

- by HardCoder1986

Hello! My problem can be described the following way: I have some data which actually is an array and could be represented as char* data with some size I also have some legacy code (function) that takes some abstract std::istream object as a param and uses that stream to retrieve data to operate. So, my question is the following - what would be the easy way to map my data to some std::istream object so that I can pass it to my function? I thought about creating a std::stringstream object from my data, but that means copying and (as I assume) isn't the best solution. Any ideas how this could be done so that my std::istream operates on the data directly? Thank you.

How to break up a table holding 100mil+ number of records?

- by Chiao

We're currently storing answers for 52 predefined questions for our clients in our matchmaking site. we have over 30million unique users summing up for worst case of a 52x30million rows. Of these 52 questions, 11 are required and always answered. Our previous solution was to open an answer table for each question. This solution distributed our answer rows for faster insert/delete/update. But it also caused us an unconventional programming such as dynamically opening a table each time a question is added/updated, or removing an answer table if it was to be destroyed permanently. We want to come up with a better solution for our third version but could't get very far yet. Any ideas to accomplish this in any other, perhaps a more conventional, way?

Adding form inputs in javascript (jquery)

- by matthewsteiner

I understand that you do something like: $('form').append('<input type="text" name="color-1" value="Hello" />'); But I have two questions about it. First off, I don't want it added to the end of the form, but after the last input in the "color" section. Secondly, where "name=color-1", I need the one to increment if they want to add more than one input, you know? So that I can process it on the server. Any ideas?

- by stackover

var element = document.getElementById("divname"); var pagerHtml ='<a href="#" class="prev">&lt Prev</a>'; for (var page = 1; page <= this.pages; page++){ `pagerHtml += '<a href="#" class="'+ page> + page + '</a> ';` } pagerHtml += '<a class="dotline" style="display:none;">........</a> pagerHtml += '<a href="#" class="next"> Next ></a>'; element.innerHTML = pagerHtml; if(this.pages > 9){ `for(var i=this.buffer;i<(this.pages-this.buffer);i++){` `("."+i+1)).hide();` } } I want to add class "dotline" so that when pages are hidden I would do $(".dash").show(); and it would look like 1,2,.....,8,9,10. any ideas would be appreciated.

Qt drag/drop: cannot move when copy is enabled (Ubuntu Gnome)

- by Scott

I'm implementing a view and a model where I want to support both moving items internally (by dragging), and copying items (by pressing Ctrl while dragging). I've done everything I need to do according to the instructions. I've set up the mime functions, I've implemented removeRows(), and flags(). The problem is when I drag, it defaults to a copy operation (I get the arrow cursor with a plus sign, and it indeed copies the item by creating a new one in the model). The only difference I can see is this: If I return only Qt::MoveAction in supportedDropActions(), it only moves. If I return (Qt::CopyAction | Qt::MoveAction), it only copies. Any ideas? I want it to work like files in Nautilus (Gnome) or Windows file Explorer: drag moves icons around, ctrl+drag copies them.

Is this a php memory leak?

- by mseifert

I have memory_get_usage() in the footer of my page and with each refresh of the page, I watch it increase by about 100k each time. My page load creates many objects and destroys them when done . My parent objects each have __destruct() which uses unset() with all child objects. Child objects with a reference back to the parent, have __destruct() to unset() these references. Inserting memory_get_usage() before and after processing different parts of my page only tells me how much of the total usage was added due to that part of the script. How do I go about determining what memory is lost and not recycled for garbage collection after the page finishes loading? I have one global $_SESSION var containing objects storing user info, but have verified using strlen(serialize($object)) that this object is not growing in size. I presume that what I am seeing is a memory leak and that php garbage collection should be in effect after the script ends. Any ideas how to debug this?

IE8 $('body').width() is 0 on $(window).load()

- by allicarn

On $(document).ready I run through a for loop twice and alert out the body's width ($('body').width();) each time through. I get a value I would expect (ex. 1092). On $(window).load I run through another for loop twice, also alerting out the body's width each time through. I get 0 the first time through (and the page looks completely blank behind the alert), and then a value I would expect the second time through (ex. 1092). This is an issue I am not able to replicate in a stripped-down example, nor any other browser (Chrome, Safari, Firefox, IE9, IE10). Does anyone have any ideas, or other things that I could test for? I am using $(window).load to cut up some divs based on their width, which is based on their font size, which is based on a webfont (which isn't necessarily loaded by the time $(document).ready fires).

ViewDidLoad not being called with my custom UIViewController

- by user1060500

I have created a custom UIViewController class that creates a ScrollView at runtime that it loads into the view. See code here in the constructor of my custom UIViewController. initControl(id, canEdit); _controllers = new NSMutableArray(0); //required to keep view controllers around _scrollView = new UIScrollView(); _scrollView.BackgroundColor = UIColor.Green; this.View = _scrollView; ViewDidAppear and ViewWillAppear are called normally. ViewDidLoad is not called which I am not sure why as the view is showing up on the screen just fine. Any ideas?

Shedule tasks question

- by gabac

Hi everyone I have a though question :) Let's say you get some data which is due at a certain point int the future. You get A saying my task is due in 1h and other which says his task is due in 1.5h. The information is collected on your server. In which programming language or even how would solve that? So task a will be executed in 1h, task B in 1.5h. I read something about java scheduler but I'm not yet sure if this is the right way. What are ur ideas? Cheers

New line before header()

- by MetalAdam

I'm working with a custom made Joomla script that generates an image from a blob in a database. However, when we moved it from an Apache server to an IIS server, the script is breaking. Upon investigation, it seems that now, there is a line break that is getting appended before the header function is being run (when I comment out the image portion, and do an echo "test";, test gets printed on line 2 of the source code. I've gone through the script over and over again, and through the many files in the component, and can't seem to find out where this new line is coming from. At all. I've tried using ob_start() and many similar functions, but nothing seems to work. I'm completely out of ideas, and don't know where to turn. Is there a way to trace what files are being called in the page, perhaps? Any thoughts on further steps?

Print number in engineering format

- by jmurrayufo

I am trying to print a number into engineering format with python, but I cannot seem to get it to work. The syntax SEEMS simple enough, but it just doesn't work. >>> import decimal >>> x = decimal.Decimal(1000000) >>> print x 1000000 >>>> print x.to_eng_string() 1000000 I cannot figure out why this is. The two values are not equal (one is a string, the other is an int). Setting various contexts in decimal doesn't seem to help either. Any clues or ideas?
