• Google Maps API v3 not working

  - by user1496322

  I've been banging my head on the wall after going through the documentation on this several times! I can't seem to get past the API error to get the map to appear on my site. I am getting the following error message from the web page where I want the map to be displayed: ~~~~~~~~~~~ Google has disabled use of the Maps API for this application. The provided key is not a valid Google API Key, or it is not authorized for the Google Maps Javascript API v3 on this site. If you are the owner of this application, you can learn about obtaining a valid key here: https://developers.google.com/maps/documentation/javascript/tutorial#Obtaining_Key ~~~~~~~~~~~ I have (several times now) gone into my account and 1) enabled the Maps v3 API service. 2) Generated a new API key. and 3) added my allowed referrers to the key. (both www.domain.com and domain.com URLs) I have the following added to the head of the web page: < script src="http://maps.googleapis.com/maps/api/js?sensor=false&key=MY_API_KEY_HERE" type="text/JavaScript" language="JavaScript" And... I have the following javascript function that executes when a link is clicked on the page: alert("viewMap()"); var map = new GMap3(document.getElementById("map_canvas")); var geocoder = new GClientGeocoder(); var address = "1600 Amphitheatre Parkway, Mountain View"; alert("Calling getLatLng ..."); geocoder.getLatLng(address, function(point) { var latitude = point.y; var longitude = point.x; // do something with the lat lng alert("Lat:"+latitude+" - Lng:"+longitude); }); The initial 'viewMap' alert is displayed and then is followed by the 'Google has disbled use...' error message. The error console is also showing 'GMap3 is not defined'. Can anyone please assist with showing me the errors of my ways?!?!? Thank you in advance for any help you can provide. -Dennis

• Flex DataGridColumn with array of objects as data provider

  - by rforte

  I have a datagrid that uses an array of objects as the data provider. The objects are essentially key/value pairs: { foo:"something"} { bar:"hello"} { caca:"lorem"} The datagrid has 2 columns. The first column is the key and the second column is the value. Right now my grid looks like: My dataFormatter function makes sure that depending on the column (i.e. the dataField value) the correct key or value gets printed out. This works fine for displaying. However, as soon as I try and edit the value field it essentially adds a new value into the object with a key of '1'. For example, if I edit the {caca:"lorem"} object it will then contain the value {caca:"lorem",1:"new value"}. Is there any possible way I can set the DataGridColumn so that when I edit a value it will update the value associated with the key rather than inserting a new value? I've tried using a custom item editor but it still does the insert. It seems like I need to be able to update the 'dataField' with the actual key value but I'm not sure how to do that.

• Need help with PHP URL encoding/decoding

  - by Kenan

  On one page I'm "masking"/encoding URL which is passed to another page, there I decode URL and start file delivering to user. I found some function for encoding/decoding URL's, but sometime encoded URL contains "+" or "/" and decoded link is broken. I must use "folder structure" for link, can not use QueryString! Here is encoding function: $urll = 'SomeUrl.zip'; $key = '123'; $result = ''; for($i=0; $i<strlen($urll); $i++) { $char = substr($urll, $i, 1); $keychar = substr($key, ($i % strlen($key))-1, 1); $char = chr(ord($char)+ord($keychar)); $result.=$char; } $result = urlencode(base64_encode($result)); echo '<a href="/user/download/'.$result.'/">PC</a>'; Here is decoding: $urll = 'segment_3'; //Don't worry for this one its CMS retrieving 3rd "folder" $key = '123'; $resultt = ''; $string = ''; $string = base64_decode(urldecode($urll)); for($i=0; $i<strlen($string); $i++) { $char = substr($string, $i, 1); $keychar = substr($key, ($i % strlen($key))-1, 1); $char = chr(ord($char)-ord($keychar)); $resultt.=$char; } echo '<br />DEC: '. $resultt; So how to encode and decode url. Thanks

• how to Solve the "Digg" problem in MongoDB

  - by user193116

  A while back,a Digg developer had posted this blog ,"http://about.digg.com/blog/looking-future-cassandra", where the he described one of the issues that were not optimally solved in MySQL. This was cited as one of the reasons for their move to Cassandra. I have been playing with MongoDB and I would like to understand how to implement the MongoDB collections for this problem From the article, the schema for this information in MySQL : CREATE TABLE Diggs ( id INT(11), itemid INT(11), userid INT(11), digdate DATETIME, PRIMARY KEY (id), KEY user (userid), KEY item (itemid) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; CREATE TABLE Friends ( id INT(10) AUTO_INCREMENT, userid INT(10), username VARCHAR(15), friendid INT(10), friendname VARCHAR(15), mutual TINYINT(1), date_created DATETIME, PRIMARY KEY (id), UNIQUE KEY Friend_unique (userid,friendid), KEY Friend_friend (friendid) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; This problem is ubiquitous in social networking scenario implementation. People befriend a lot of people and they in turn digg a lot of things. Quickly showing a user what his/her friends are up to is very critical. I understand that several blogs have since then provided a pure RDBMs solution with indexes for this issue; however I am curious as to how this could be solved in MongoDB.

• Connect.registerUsers - Need helping creating array for accounts param

• Mysql slow query: INNER JOIN + ORDER BY causes filesort

  - by Alexander

  Hello! I'm trying to optimize this query: SELECT `posts`.* FROM `posts` INNER JOIN `posts_tags` ON `posts`.id = `posts_tags`.post_id WHERE (((`posts_tags`.tag_id = 1))) ORDER BY posts.created_at DESC; The size of tables is 38k rows, and 31k and mysql uses "filesort" so it gets pretty slow. I tried to use different indexes, no luck. CREATE TABLE `posts` ( `id` int(11) NOT NULL auto_increment, `created_at` datetime default NULL, PRIMARY KEY (`id`), KEY `index_posts_on_created_at` (`created_at`), KEY `for_tags` (`trashed`,`published`,`clan_private`,`created_at`) ) ENGINE=InnoDB AUTO_INCREMENT=44390 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci CREATE TABLE `posts_tags` ( `id` int(11) NOT NULL auto_increment, `post_id` int(11) default NULL, `tag_id` int(11) default NULL, `created_at` datetime default NULL, `updated_at` datetime default NULL, PRIMARY KEY (`id`), KEY `index_posts_tags_on_post_id_and_tag_id` (`post_id`,`tag_id`) ) ENGINE=InnoDB AUTO_INCREMENT=63175 DEFAULT CHARSET=utf8 +----+-------------+------------+--------+--------------------------+--------------------------+---------+---------------------+-------+-----------------------------------------------------------+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+------------+--------+--------------------------+--------------------------+---------+---------------------+-------+-----------------------------------------------------------+ | 1 | SIMPLE | posts_tags | index | index_post_id_and_tag_id | index_post_id_and_tag_id | 10 | NULL | 24159 | Using where; Using index; Using temporary; Using filesort | | 1 | SIMPLE | posts | eq_ref | PRIMARY | PRIMARY | 4 | .posts_tags.post_id | 1 | | +----+-------------+------------+--------+--------------------------+--------------------------+---------+---------------------+-------+-----------------------------------------------------------+ 2 rows in set (0.00 sec) What kind of index I need to define to avoid mysql using filesort?

• Is there an efficient way in LINQ to use a contains match if and only if there is no exact match?

  - by Peter

  I have an application where I am taking a large number of 'product names' input by a user and retrieving some information about each product. The problem is, the user may input a partial name or even a wrong name, so I want to return the closest matches for further selection. Essentially if product name A exactly matches a record, return that, otherwise return any contains matches. Otherwise return null. I have done this with three separate statements, and I was wondering if there was a more efficient way to do this. I am using LINQ to EF, but I materialize the products to a list first for performance reasons. productNames is a List of product names (input by the user). products is a List of product 'records' var directMatches = (from s in productNames join p in products on s.ToLower() equals p.name.ToLower() into result from r in result.DefaultIfEmpty() select new {Key = s, Product = r}); var containsMatches = (from d in directMatches from p in products where d.Product == null && p.name.ToLower().Contains(d.Key) select new { d.Key, Product = p }); var matches = from d in directMatches join c in containsMatches on d.Key equals c.Key into result from r in result.DefaultIfEmpty() select new {d.Key, Product = d.Product ?? (r != null ? r.Product: null) };

• Should TcpClient be used for this scenario?

  - by Martín Marconcini

  I have to communicate with an iPhone. I have its IP Address and the port (obtained via Bonjour). I need to send a header that is “0x50544833” (or similar, It’s an HEX number), then the size of the data (below) and then the data itself. The data is just a string that looks like this: <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE plist SYSTEM "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>clientName</key> <string>XXX</string> <key>clientService</key> <string>0be397e7-21f4-4d3c-89d0-cdf179a7e14d</string> <key>registerCode</key> <string>0000</string> </dict> </plist> The requirement also says that I must send the data in little endian format (which I think is the default for Intel anyway). So it would be: hex_number + size of data + string_with_the_above_xml. I need to send that to the iPhone and read the response. What would be, according to your experience, the best way to send this data (and read the response)?

• Nhibernate:null index column for collection Error

• Actionscript Enterframe Movement

  - by David

  I am trying to make accelerated movement, but I am running into a problem that, for the life of me, I cannot understand. My class definition: public class Player extends MovieClip { private var stageRef:Stage; private var key:KeyObject; private var acceleration:int = .5; private var curSpeed:int = 0; public function Player(stageRef:Stage) { this.stageRef = stageRef; addEventListener(Event.ENTER_FRAME, enterFrame); key = new KeyObject(stageRef); } public function enterFrame(e:Event) : void { if(key.isDown(key.RIGHT)) { x += 5; } } } This works to move my position in the x direction at a constant rate. However, if I change enterFrame to public function enterFrame(e:Event) : void { if(key.isDown(key.RIGHT)) { x += acceleration; } } No movement occurs. Is there something going on in the event I do not understand? Why is it that I can have x increased by a constant value but not a constant value as defined in a variable in the class? Is it a scope issue?

Everything is open to scrutiny, this is my first time creating a ranking system so I hope to get it right :)

• Windows XP 32-bit + RocketRaid 622 + 4 x 3TB = not quite a RAID setup

  - by gmoney

  I'm looking to make a 6TB RAID 10 array from my new pile of drives under Windows XP 32-bit, however they are only for auxiliary storage. After adding all the drives to an array, and initializing them XP sees only a fraction of the storage, 2TB. I'm assuming this has to do with MBR vs GPT. Is making a series of 2TB volumes and then spanning my only solution? Most questions online have to do with booting from this setup, but I'm just using them as extra storage. Hardware: 4 x 3TB Hitachi Deskstars + RocketRaid 622 + Sans Digital TR8M TowerRAID. The array is connected via eSATA.

• Elegant and 'correct' multiton implementation in Objective C?

  - by submachine

  Would you call this implementation of a multiton in objective-c 'elegant'? I have programmatically 'disallowed' use of alloc and allocWithZone: because the decision to allocate or not allocate memory needs to be done based on a key. I know for sure that I need to work with only two instances, so I'm using 'switch-case' instead of a map. #import "Multiton.h" static Multiton *firstInstance = nil; static Multiton *secondInstance = nil; @implementation Multiton + (Multiton *) sharedInstanceForDirection:(char)direction { return [[self allocWithKey:direction] init]; } + (id) allocWithKey:(char)key { return [self allocWithZone:nil andKey:key]; } + (id)allocWithZone:(NSZone *)zone andKey:(char)key { Multiton **sharedInstance; @synchronized(self) { switch (key) { case KEY_1: sharedInstance = &firstInstance; break; case KEY_2: sharedInstance = &secondInstance; break; default: [NSException raise:NSInvalidArgumentException format:@"Invalid key"]; break; } if (*sharedInstance == nil) *sharedInstance = [super allocWithZone:zone]; } return *sharedInstance; } + (id) allocWithZone:(NSZone *)zone { //Do not allow use of alloc and allocWithZone [NSException raise:NSObjectInaccessibleException format:@"Use allocWithZone:andKey: or allocWithKey:"]; return nil; } - (id) copyWithZone:(NSZone *)zone { return self; } - (id) retain { return self; } - (unsigned) retainCount { return NSUIntegerMax; } - (void) release { return; } - (id) autorelease { return self; } - (id) init { [super init]; return self; } PS: I've not tried out if this works as yet, but its compiling cleanly :)

• Complex Quary on cassandra

  - by Sadiqur Rahman

  I have heard on cassandra database engine few days ago and searching for a good documentation on it. after studying on cassandra I got cassandra is more scalable than other data engine. I also read on Amazon SimpleDB but as SimpleDB has a limitation 10GB/table and Google Datastore is slower than Amazon SimpleDB, I prefer not to use them (Google Datastore, Amazon SimpleDB). So for making our site scaled specially high write rates with massive data, I like to use Cassandra as out Data Engine. But before starting using cassandra I am confused on "How to handle complex data using casssandra". I am giving you the MySQL database structure below, Please read this and give me a good suggestion.

• Which has a faster data transfer rate? WIFI (tablet or cell phone, not LTE) or MicroSD (Class 10)?

  - by techaddict

  Which of the two methods of dta transfer trasfers data at a faster rate for smartphones and tablets? Standard WIFI, or MicroSD Cards? I wonder if it would be actually faster to access data on external storage then it would be to have the MicroSD card in my smartphone or tablet. Currently I have a class 10 32GB MicroSD card in my cell phone. I am looking to get the new Google Nexus tablet but it does not offer expandable internal storage. I wonder if that's really a detriment; because if WIFI is faster than MicroSD, then it would matter almost none at all that you couldn't expand the storage internally. If the case is that WIFI is faster, and people caught onto this, then people could save a lot of money on lower memory ipads/iphones/ipods, tablets, and smartphones!

• Outlook '10 hangs often, IMAP sync

  - by user23150

  We have 3 employees using IMAP to sync with their Desktop and Android Phones. Two are using 70% of their accounts storage, another is using 80%. They all have similar counts on folder structure, etc. The employee with the 80% storage is constantly having Outlook freeze on them for up to 5 minutes at a time. I realize this is Outlook connecting and doing activity on the server, but no one else has this problem. In fact, one user with the 70% storage used uses a very slow laptop, and doesn't have freezing issues. The network is the same, the settings are the same - at a loss how to proceed? Obviously "Outlook is a crummy IMAP client" doesn't help management...

• PyQt - How to connect multiple signals to the same widget

  - by Orchainu

  [ ]All1 [ ]All2 [ ]checkbox1A [ ]checkbox1B [ ]checkbox2A [ ]checkbox2B Based on the chart above, a few things need to happen: The All checkboxes only affect the on/off of the column it resides in, and checks on/off all the checkboxes in that column. All checkboxes work in pairs, so if checkbox1A is on/off, checkbox1B needs to be on/off If an All checkbox is checked on, and then the user proceeds to check off one or more checkbox in the column, the All checkbox should be unchecked, but all the checkboxes that are already checked should remain checked. So really this is more like a chain reaction setup. If checkbox All1 is on, then chieckbox1A and 2A will be on, and because they are on, checkbox1B and 2B are also on, but checkbox All2 remains off. I tried hooking up the signals based on this logic, but only the paired logic works 100%. The All checkbox logic only works 50% of the time, and not accurately, and there's no way for me to turn off the All checkbox without turning all already checked checkboxes off. Really really need help ... T-T Sample code: cbPairKeys = cbPairs.keys() for key in cbPairKeys: cbOne = cbPairs[key][0][0] cbTwo = cbPairs[key][1][0] cbOne.stateChanged.connect(self.syncCB) cbTwo.stateChanged.connect(self.syncCB) def syncCB(self): pairKeys = cbPairs.keys() for keys in pairKeys: cbOne = cbPairs[keys][0][0] cbOneAllCB = cbPairs[keys][0][4] cbTwo = cbPairs[keys][1][0] cbTwoAllCB = cbPairs[keys][1][4] if self.sender() == cbOne: if cbOne.isChecked() or cbTwoAllCB.isChecked(): cbTwo.setChecked(True) else: cbTwo.setChecked(False) else: if cbTwo.isChecked() or cbOneAllCB.isChecked(): cbOne.setChecked(True) else: cbOne.setChecked(False) EDIT Thanks to user Avaris's help and patience, I was able to reduce the code down to something much cleaner and works 100% of the time on the 1st and 2nd desired behavior: #Connect checkbox pairs cbPairKeys = cbPairs.keys() for key in cbPairKeys: cbOne = cbPairs[key][0][0] cbTwo = cbPairs[key][1][0] cbOne.toggled.connect(cbTwo.setChecked) cbTwo.toggled.connect(cbOne.setChecked) #Connect allCB and allRO signals cbsKeys = allCBList.keys() for keys in cbsKeys: for checkbox in allCBList[keys]: keys.toggled.connect(checkbox.setChecked) Only need help on turning off the All checkbox when the user selectively turns off the modular checkboxes now

• Resetting Globals With Importing

  I have this code (Reset.py) that works how I want it to unless I import it. class Res(object): defaults={} class NoKey: pass def __init__(self): for key, values in defaults.items(): globals()[key]=values def add_defaults(key, values): Res.defaults[key]=value def remove_defaults(key=NoKey, remove_all=False): if remove_all: defaults={} else: del defaults[key] Without importing: >>> a=54 >>> Res.add_default('a', 3) >>> Res() <__main__.Res object at 0x> >>> a 3 >>> #great! :D With importing: >>> a=54 >>> Res.add_default('a', 3) >>> Res() <Reset.Res object at 0x> >>> a 54 This must mean when it is imported it changes the globals() under Reset and not __main__.

• How to host my own cloud so that videos are viewable via desktop web browser?

  - by jake9115

  I want to host my own cloud storage solution, something like Dropbox but entirely dependent on my own central machine. This way things are more secure if setup correctly, and there are artificial storage limitations or pay-walls. Some thing similar to ownCloud: http://owncloud.org/ There is one important feature I want to have: the ability the stream movies in a web browser from my personal cloud to anywhere in the world. In the past I tried this with a NAS, and I mapped XBMC to the NAS via SFTP, and certain media types could stream in this manner. I've also used things like PLEX. In this case, I am looking for a single solution for personal cloud storage and movie streaming from that cloud into a web browser. Does anyone know if this can be accomplished? Thanks for the suggestions!

  i use a script to upload a couple of images to a directory. the code works great in case of just one picture will be uploaded. if i like to upload two images or more and have an extension that is not accepted, the script will upload the one with the extension that is allowed to upload and shows the errormessage for the one who is not accepted. but the upload takes place. that's my first problem. second problem will be: in case of an errormessage i would like to display a message in which it is said, which of the images will be not allowed. i do not know how to fetch this one that has an unaccepted ending into a variable that i can echo to the errormessage. here is the code i use: if(!empty($_FILES['image']['tmp_name'])){ $allowed_extension = array('jpg', 'jpeg', 'png', 'bmp', 'tiff', 'gif'); foreach($_FILES['image']['name'] as $key => $array_value){ $file_name = $_FILES['image']['name'][$key]; $file_size = $_FILES['image']['size'][$key]; $file_tmp = $_FILES['image']['tmp_name'][$key]; $file_extension = strtolower(end(explode('.', $file_name))); if (in_array($file_extension, $allowed_extension) === false){ $errors[] = 'its an unaccepted format in picture $variable_that_count'; continue; } if ($file_size > 2097152){ $errors[] = 'reached maxsize of 2MB per file in picture $variable_that_count'; } if (count($errors) == 0){ $path = "a/b/c/"; $uploadfile = $path."/".basename($_FILES['image']['name'][$key]); if (move_uploaded_file($_FILES['image']['tmp_name'][$key], $uploadfile)){ echo "success."; } } } } hope it will be clear what i like to approach. if there is someone who could help out i really would appreciate. thanks a lot.

• Deleting from 2 arrays of dictionaries

  - by Matt Winters

  I have an array of dictionaries loaded from a plist (below) called arrayHistory. <plist version="1.0"> <array> <dict> <key>item</key> <string>1</string> <key>result</key> <string>8.1</string> <key>date</key> <date>2009-12-15T19:36:59Z</date> </dict> ... </array> </plist> I filter this array based on 'item' so that a second array, arrayHistoryDetail has the same structure as arrayHistory but only contains e.g. 'item's equal to '1'. These detail items are successfully displayed in a tableView. I then want to select an item from the tableView, and delete it from the tableView data source, arrayHistoryDetail (line 2 in the code below) - works, then I want to delete the item from the tableView itself (line 3 in the code below) - also works. My problem is that I also need to delete it from the original arrayHistory, so I tried the following: created a temporary dictionary as an ivar: NSMutableDictionary *tempDict; @property (nonatomic, retain) NSMutableDictionary *tempDict; Then my thinking was to make a copy in line 1 and remove it from the original array in line 4. 1 tempDict = [arrayHistoryDetail objectAtIndex: indexPath.row]; 2 [arrayHistoryDetail removeObjectAtIndex: indexPath.row]; 3 [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; 4 [arrayHistory removeObject:tempDict]; Didn't work. Could someone please guide me in the right direction. I'm thinking that tempDict is a pointer and that removeObject needs a copy? I don't know. Thanks.

• reading keyboard input without "consuming" it in x86 assembly

  - by Bob

  Ok so here the deal: I have an assignment regarding DOS and interrupts: I need to write a sort of key-logger function that can be called from C code. what it means is a c program would call an assembly function called startlog that would indicate to start logging the keys pressed until a function called endlog is called. the logging should work like this: write the ascii value of any key pressed without disturbing the C code between startlog and endlog, meaning that if the C code also needs to read the input (let's say by scanf, it would work ok). I managed to write the logger by changing the interrupt vector 9th entry (interrupt for keyboard press) to a function I wrote that writes the values to a file, and it works fine. however the C code does not get the input. Basically what i did is read the key pressed using int 21h, however after reading the ascii value it is "consumed" so I need a way to either simulate the key press again or read the value without "consuming" it so next time a key is read it reads the same key. (I described the code in english because it is long and clumsy assembly code)

• How to make smooth movements in OpenGL?

  - by thyrgle

  So this kind of on topic to my other OpenGL question (not my OpenGL ES question but OpenGL the desktop version). If you have someone press a key to move a square how do you make the square movement naturally and less jumpy but also at the same speed I have it now? This is my code for the glutKeyboardFunc() function: void handleKeypress(unsigned char key, int x, int y) { if (key == 'w') { for (int i = 0; i < 12; i++) { if (i == 1 || i == 7 || i == 10 || i == 4) { square[i] = square[i] + 1; } } glutPostRedisplay(); } if (key == 'd') { for (int i = 0; i < 12; i++) { if (i == 0 || i % 3 == 0) { square[i] = square[i] + 1; } } glutPostRedisplay(); } if (key == 's') { for (int i = 0; i < 12; i++) { if (i == 1 || i == 7 || i == 10 || i == 4) { square[i] = square[i] - 1; } } glutPostRedisplay(); } if (key == 'a') { for (int i = 0; i < 12; i++) { if (i == 0 || i % 3 == 0) { square[i] = square[i] - 1; } } glutPostRedisplay(); } } I'm sorry if this doesn't quite make sense I'll try to rephrase it in a better way if it doesn't make sense.
