What weird encoding is movistar Venezuela sms on blackberry using?

- by cjp

Send an sms using the normal GSM TextMessage API on the BlackBerry, get back garbage. It's not unicode, phone is set to 7-bit send. Byte size is only off by one. Is there some default crypto thing, or some weird encoding they use? This code works most everywhere else in the world; this definitely seems like a movistar problem. The string that comes back is random 7-bit ascii except for a few high order bytes. Needless to say the source input text is totally 7 bit chars, which should work in sms, ISO-8859 and look the same in UTF charsets. Anybody seen this or got sms working in code on movistar VZ blackberries?

Select rows where column LIKE dictionary word

- by Gerve

I have 2 tables: Dictionary - Contains roughly 36,000 words CREATE TABLE IF NOT EXISTS `dictionary` ( `word` varchar(255) NOT NULL, PRIMARY KEY (`word`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1; Datas - Contains roughly 100,000 rows CREATE TABLE IF NOT EXISTS `datas` ( `ID` int(11) NOT NULL AUTO_INCREMENT, `hash` varchar(32) NOT NULL, `data` varchar(255) NOT NULL, `length` int(11) NOT NULL, `time` int(11) NOT NULL, PRIMARY KEY (`ID`), UNIQUE KEY `hash` (`hash`), KEY `data` (`data`), KEY `length` (`length`), KEY `time` (`time`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=105316 ; I would like to somehow select all the rows from datas where the column data contains 1 or more words. I understand this is a big ask, it would need to match all of these rows together in every combination possible, so it needs the best optimization. I have tried the below query, but it just hangs for ages: SELECT `datas`.*, `dictionary`.`word` FROM `datas`, `dictionary` WHERE `datas`.`data` LIKE CONCAT('%', `dictionary`.`word`, '%') AND LENGTH(`dictionary`.`word`) > 3 ORDER BY `length` ASC LIMIT 15 I have also tried something similar to the above with a left join, and on clause that specified the like statement.

best way to write a-> ..->[a] recursive functions in haskell

- by Roman A. Taycher

So I keep having this small problem where I have something like func :: a -> b -> [a] -- or basically any a-> ...-> [a] where ... is any types -> func x y = func' [x] y -- as long as they are used to generate a list of [a] from x func' :: [a] -> b -> [a] func = undefined --situation dependant generates a list from each element and returns it as one long list should I keep it like this? should I use func' hidden by a where? should I only use the [a] - b - [a] version and leave the responsibility of passing [variable] to the callee? I might well need to compose these functions and might want to mess around with the order so I'm leaning towards option 3. What do you think?

BST Level Traversal

- by Dalton Conley

Ok, so I'm trying to do a level order traversal of a binary search tree and its not working. The code below makes sense to me, but that is probably because I've been looking at it forever and I've convinced myself that it should work. void BST<T>::levelByLevel(ostream &out) { Queue<BinNodePointer> q; BinNodePointer subtreeRoot; if(myRoot == NULL) return; q.enqueue(myRoot); while(!q.empty()) { subtreeRoot = q.front(); out << subtreeRoot->data << " "; q.dequeue(); if(subtreeRoot->left != NULL) q.enqueue(subtreeRoot->left); if(subtreeRoot->right != NULL) q.enqueue(subtreeRoot->right); } } Maybe you guys could point out what I'm doing wrong because, although I understand the concept of a binary search tree, I'm not 100% on all the ins and outs.

OPENGL Android getting the coordinates of my image

- by Debopam

I used the codes from the following the website. And it helped a lot to draw the required object on my screen. But the problem I am facing is getting the coordinates of my object. Let me explain. According to the code. You just need to add your graphic images in PNG format and refer it to the class here. What I am trying to achieve is a simple collision detection mechanism. I have added a maze (as PNG). And have a object (as PNG) to go through the blank path within the maze. In order to do this I need to know the blank spaces within the coordinates through which my object will move. Can any one tell me how to get the blank spaces as (x,y) coordinates through which I can take my object?

How to track conversion rate (clicks to sales) from an internal advertising system?

- by Ed Woodcock

I am currently writing an interal advertising system for a company client's website, where the adverts will only be seen by internal users, and all transactions take place internally to the site (i.e. the adverts are for member-only content available on the site). Does anyone have any recommendations as to the best way to track the conversion rate of these adverts (i.e. views:clicks:sales)? EDIT I'm not looking for a 'Why don't you use google analystics'-type answer, I'm looking into possible architecture outlines, i.e. a 'why don't use store a guid in a cache temporarily and see if it ties to the advert' kind of answer. /EDIT In a previous job I did something based on an internal cache, which simply did view:click tracking, however the addition of the sales rate makes this task more complex, especially if we take into account the idea that someone may click through to an advert and not purchase immediately. Cheers, Ed (N.B. I'm leaving this purposely vague in order to (hopefully) get some answers that provide ideas I've yet to have thought of by coming at the problem from a different angle)

Overriding Magento Admin Controller, for Beginners

- by Knowledge Craving

In the Magento Admin section, I want to override the "Sales/Order/ShipmentController.php" controller file of the core Mage. I have tried rewriting the URL, using the "from" & "to" tags, but in vain. I don't know what is the actual & correct way of doing this, as I'm a newbie in Magento. Please anybody provide some good fundamental & correct answer, so that at least the concept gets clear. Also, if possible, please tell me, what is the actual purpose of the controller, for both the frontend & the back-end? Any help is greatly appreciated.

What is the correct way to customize Icon and Text position of items in a QListView?

- by petermcg

I'm using C++ and Qt's (4.6) model/view framework and wondering what is the correct way to change the display of items in a QListView or a class derived from QListView from: to: I'm not concerned about the sort order or Flow, I'm interested in the best way to correctly position the text to the right of the icon. If this can only be done by writing a custom QStyledItemDelegate that's totally fine, I want to rule out whether this is the correct approach or whether it's best to look at setLayout or similar, example code would help. The example application I'm looking at is the 'interview' example from qtdemo which amongst other things displays icons and text in a QListView.

ASP.NET 2.0 control is not shown up un VS 2010 toolbox

- by user353653

Hi, I have developed some ASP.NET controls in .NET 2.0 with VS 2008. Now, I upgraded my project to VS 2010 but did not change the target framework to .NET 4.0 yet. But, surprisingly, I found that, the toolbox is not showing the bitmaps for the control added to the toolbox in VS 2010. Moreover, when I dragged and dropped a control (.NET 2.0) from the toolbox to my Web Form, I see some junk xml code added to my web form. I dont know if I need to recompile the .NET 2.0 controls with VS 2010 ? or what should I do in order to make the controls compatible for both in VS 2008 and VS 2010 ? I found that, there is no problem with Windows Forms control, rather it is just with ASP.NET Controls.

.htaccess for multiple application in Kohana V3

Hi I have setup multiple application in Kohana v3, it works normally without enabling .htaccess (to remove index.php or admin.php) my setup + system/ + modules/ + applications/ + public/ + bootstrap.php + ... + admin/ + bootstrap.php + ... + index.php (for 'public' application) + admin.php (for 'admin' application) so to access the frontend sample url will be; http://mydomain.com/index.php/(controller_name)/... and to access administration site; http://mydomain.com/admin.php/(controller_name)/... The task is, I want to remove and replace index.php (default url) and admin.php with /admin/ using .htaccess (mod_rewrite) so it can be http://mydomain.com/(controller_name) <- 'public' application http://mydomain.com/admin/(controller_name) <- 'admin' application my current .htaccess (not working) is; # Turn on URL rewriting RewriteEngine On # Installation directory RewriteBase /ko3/ # Protect hidden files from being viewed Order Deny,Allow Deny From All # Protect application and system files from being viewed RewriteRule ^(?:web-apps|modules|core)\b.* index.php/$0 [L] # Allow any files or directories that exist to be displayed directly RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d # TODO: rewrite admin URL to admin.php/URL #RewriteRule ^admin/(.*) admin.php/$0 [L] # Rewrite all other URLs to index.php/URL RewriteRule .* index.php/$0 [PT]

Is there a point creating a site using XSLT

- by webwise

Is this technology still popular? I want to make a website which automatically transforms XSLT files. It should work like this: When a user accesses the site, a single handler would accept his request and then find a suitable XML for it (according to the URL requested) and transform it using its attached XSL file. I want to do this in order to make it easy to update the site using plain XML files (instead of using a full-fledged & expensive CMS system). What do you say? good idea? bad idea? anyone has a recommendation? Thanks!

The delegate method "clickedButtonAtIndex:" is not called.

- by sagiftw

Hello everyone! I have created an alert view with two buttons using the following code: UIAlertView *alertView = [[UIAlertView alloc] initWithTitle: title message: msg delegate:nil cancelButtonTitle:@"Replay" otherButtonTitles:@"Highscore", nil]; [alertView show]; I want to run some code when one of the buttons is clicked. In order to do so, I have added the following method to the delegate.m file: - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex { if (buttonIndex==0) //Run some code else //Other code } But this method is not called when I press either of the buttons! Can someone tell me why? Thanks in advance, Sagiftw

Joining two select queries and ordering results

- by user1

Basically I'm just unsure as to why this query is failing to execute: (SELECT replies.reply_post, replies.reply_content, replies.reply_date AS d, members.username FROM (replies) AS a INNER JOIN members ON replies.reply_by = members.id) UNION (SELECT posts.post_id, posts.post_title, posts.post_date AS d, members.username FROM (posts) as b WHERE posts.post_set = 0 INNER JOIN members ON posts.post_by = members.id) ORDER BY d DESC LIMIT 5 I'm getting this error: #1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'a INNER JOIN members ON replies.re' at line 2 All I'm trying to do is select the 5 most recent rows (dates) from these two tables. I've tried Join, union etc and I've seen numerous queries where people have put another query after the FROM statement and that just makes no logical sense to me as to how that works? Am I safe to say that you can join the same table from two different but joined queries? Or am I taking completely the wrong approach, because frankly I can't seem see how this query is failing despite reading the error message. (The two queries on there own work fine)

Hold most of the object in cache/memory insted of database?

- by feiroox

Hi All, It just occurred to me why not to have most of the objects in a cache(memory) when an application start. if it's not that large web application. Or to have a settings for how much I want to put in the cache/memory. I just guess it could require to have something like below 1 GB RAM or a lot less. Everything in order to speed up the application even more by not querying database. Is it good idea?

LINQ Expression help with Func TEntity,TType

- by Chris Conway

I have a repository method that accepts an order by parameter in the form: public IEnumerable<TEntity> Get<TEntity>(Expression<Func<TEntity,string>> orderBy) Now that works fine when trying to sort by a property of type string, var entities = rep.Get(x => x.Name); but what if i want to sort by double or int or any other type. Doing something like var entities = rep.Get(x => x.Price); obviously throws a compile error saying I can't convert double to string. How can I make this more generic so I can sort by any property in my entity, or at least the properties where the type implements IComparable or something similar?

How to replicate Google "Hangouts On Air" stream combining functionality?

- by Rob Olmos

I've been researching this one for quite a bit but haven't found any solid leads. I have a Wowza/Flash app with video chatroom functionality and would like to combine the streams server-side into one video/audio stream in order to be sent to a live Youtube channel. I've found a couple projects such as jMixer and some helpful keywords such as "vision mixer" to help with my search but looking for any previous experience or new ideas. The other option is building something like it myself with a commercial video decoding/encoding library to raw frames, stitching the frames together, then encoding it. I was originally going down this route but put project on hold. What are some ideas, keywords, or existing software (open source preferred) to take those live streams and combine them into one in real-time? Or is coding it myself the required route? Thanks!

How can I save/print values in my WATCH list in Visual Studio 2008?

- by Rising Star

When I attach the Visual Studio 2008 debugger to my web server process, I sometimes browse a large amount of data in my watch list. Suppose I have an array of string variable that I expand to show 20 entries. It seems that the only way to save these values is to copy and paste them one at a time. I have gone so far as to do a screen-shot in order to have a record of what the values were (to refer to later or print a hard copy). Is there an easy way to save and print these values? I am familiar with the new "IntelliTrace" feature in Visual Studio 2010 Ultimate, but it seems overkill for this purpose. I just want to take something like an array of strings and save it for later reference once I've stopped the debugger. What's a good way to do this?

What happens when I MPI_Send to a process that has finished?

- by nieldw

What happens when I MPI_Send to a process that has finished? I am learning MPI, and writing a small sugar distribution-simulation in C. When the factories stop producing, those processes end. When warehouses run empty, they end. Can I somehow tell if the shop's order to a warehouse did not succeed(because the warehouse process has ended) by looking at the return value of MPI_Send? The documentation doesn't mention a specific error code for this situation, but that no error is returned for success. Can I do: if (MPI_Send(...)) { ... /* destination has ended */ ... } And disregard the error code? Thanks

Allow users to enter a variable length list of items in asp.net form

- by EJB

I need to let my users enter a variable length list of items into something that looks like a grid view (or a series of standard text boxes stacked vertically). Each item could be a few characters or a few hundred characters long, and I just want them to enter a "sentence", and then tab to the next row, and always having another blank one ready to go at the bottom of the list. I don't want to save any data to my SQL Server DB until they enter the entire list and then click on a "save all" button. When they hit the "save all" button they will be given a preview screen where the data will be presented as standard HTML ordered list. If they confirm/save, then each row of the grid will then be saved as a separate row into my SQL Server database (with an index to remember the order). What ASP.Net (or Jquery/javascript) UI control would be the best to use in this situation?

Purely functional equivalent of weakhashmap?

- by Jon Harrop

Weak hash tables like Java's weak hash map use weak references to track the collection of unreachable keys by the garbage collector and remove bindings with that key from the collection. Weak hash tables are typically used to implement indirections from one vertex or edge in a graph to another because they allow the garbage collector to collect unreachable portions of the graph. Is there a purely functional equivalent of this data structure? If not, how might one be created? This seems like an interesting challenge. The internal implementation cannot be pure because it must collect (i.e. mutate) the data structure in order to remove unreachable parts but I believe it could present a pure interface to the user, who could never observe the impurities because they only affect portions of the data structure that the user can, by definition, no longer reach.

WPF: Menu items and combo boxes don't render in Windows 7 64-bit

- by lilserf

I'm trying to use an existing internal WPF application (I do have access to the source), but it was developed on XP and I'm using Windows7 64-bit. When I click (for instance) the File menu, 90% of the time I see no drop-down menu at all. The menu still exists - I can use the arrow keys to navigate up and down and choose an option if I happen to know the order of the options, but nothing renders at all. The other 10% of the time, the menu or some portion of it DOES render, but as I move the cursor up and down I get graphical corruption or disappearing options until I end up back at the "no menu is visible at all" state. This is also true of combo boxes within the application - they show no data when I drop them down, but I can arrow down and choose an entry. Microsoft has some advice about WPF rendering issues here but none of these steps has helped with my issue.

bash copy with variable

I'm trying to copy files to the current directory using a bash script. In order to handle paths that need escaping a variable is used that is escaped and then supplied to the cp command. The cp command is complaining with: usage: cp [-R [-H | -L | -P]] [-fi | -n] [-apvX] source_file target_file cp [-R [-H | -L | -P]] [-fi | -n] [-apvX] source_file ... target_directory I know what that means but I cannot understand why that happens. Here is the code: z="/a/b/c d e f.txt" y=`printf %q "$z"` cp $y x.txt # not working as expected echo cp $y x.txt # output is "cp /a/b/c\ d\ e\ f.txt x.txt"
