  • Efficient way to create/unpack large bitfields in C?

    - by drhorrible
    I have one microcontroller sampling from a lot of ADC's, and sending the measurements over a radio at a very low bitrate, and bandwidth is becoming an issue. Right now, each ADC only give us 10 bits of data, and its being stored in a 16-bit integer. Is there an easy way to pack them in a deterministic way so that the first measurement is at bit 0, second at bit 10, third at bit 20, etc? To make matters worse, the microcontroller is little endian, and I have no control over the endianness of the computer on the other side.

  • how to create an excel file in google app engine (java)?

    - by Joseph
    A question that seems to have quite a few options for Python, but none for Java after googling for two days. Really really could use some help all I have found so far is a recommendation to use gaeVFS to build an excel file from the xml components and then zip it all together which sounds like a slap in the face. Oh yes and if you were wondering I am questioning my use of Java rather than python but at 5,000 lines of code it would be insane to turn back now... Other things you might find useful Client: GWT Server: Servlets running on google app engine storing data into the google data store Excel file: mandatory, CSV isn't good enough, no need to save the file just to be able to "serve" it to the client i.e. open a "Save As" box.

  • What's a good plugin or guide I can use to create javascript widgets from a Rails App?

    - by nicosuria
    I've been looking around for a while now and the best guide I've seen so far is Dr Nic's DIY widgets how to (here). I haven't been able to make something like this work: Assuming this is my widget code: <script src="http://mysite/nomnoms.js"> </script> And my nomnoms controller looks like (assume that the list partial exists and simply lists down a link to the show page of each nomnom in the @nomnoms variable): class NomnomsController < ApplicationController def index @nomnoms = Nomnom.find(:all) @content = render_to_string(:partial => 'list') end end And in the index.js of my nomnoms_controller I have: page << "document.write('<div>'" page << "document.write('#{@content.to_json}')" page << "</div>" The above setup doesn't render anything :(. But when I change the second line of index.js to: page << "document.write('nomnoms should be here') ...the widget renders the text. Any help or even a point in the right direction would be greatly appreciated. Thanks in advance.

  • Need to remotely create an ODBC connection to a SQl server.

    - by kris
    I have an Access 2007 database with a table in it that is linked to a SQL server. I need to roll this version of the database out to approximately 10 people in different states. In order to do that, they need an ODBC connection to the SQL server installed on their machines. I am looking for a way to do this remotely. Either through VBA in the database itself or perhaps a Batch file linked to their shortcut....I am open to ideas....

  • Google Maps: How does Trulia create their custom InfoWIndows?

    - by NickT
    I really like how Trulia.com has created their custom Google Map InfoWindows. What I like in particular about Trulia's implementation of the InfoWindow is: Extends beyond the map border: Google Maps InfoWindows are contained within the map border whereas Trulia's seems to be able to float on-top of the map Always displays InfoWindow near map Center: Google Maps InfoWindows always display the InfoWindow above the marker whereas Trulia InfoWindows always display the InfoWindow as close the center of the map as possible. For example, if the map marker icon is on the top of the map near the border, the Trulia InfoWindow is displayed below the map marker icon InfoWindow is displayed on mouse hover (not 'click'): With the default Google Maps InfoWindow, you have to 'click' the map marker icon to display the InfoWindow whereas Trulia InfoWindows are display simply by hovering over the map marker icon. I found the PdMarker, which is a 3rd party extension for Google Map InfoWindows that accomplishes most of the above bullets but not all. 1) It does not extend beyond the map border, 2) it does not work with Google Maps API version 3 (only version 2). Anyone know how Trulia is accomplishing their InfoWindow-like implementation on Google Maps API v3?

  • PHP Uploadprogress extension function always returning null, with no upload data.

    - by abhinavlal
    I am using php 5.3.2 with uploadprogress extension to get a progressbar during upload using zend framework. Even the demo provided with zend is not working. code in zend example - if (isset($_GET['uploadId'])) { set_include_path(realpath(dirname(__FILE__) . '/../../../library') . PATH_SEPARATOR . get_include_path()); require_once 'Zend/ProgressBar.php'; require_once 'Zend/ProgressBar/Adapter/JsPull.php'; require_once 'Zend/Session/Namespace.php'; $data = uploadprogress_get_info($_GET['uploadId']); $bytesTotal = ($data === null ? 0 : $data['bytes_total']); $bytesUploaded = ($data === null ? 0 : $data['bytes_uploaded']); $adapter = new Zend_ProgressBar_Adapter_JsPull(); $progressBar = new Zend_ProgressBar($adapter, 0, $bytesTotal, 'uploadProgress'); if ($bytesTotal === $bytesUploaded) { $progressBar->finish(); } else { $progressBar->update($bytesUploaded); } } uploadprogress_get_info always returns null. I thought something is wrong with my code so i downloaded the working sample available at http://labs.liip.ch/uploadprogresssimple/index.php but even in that case in uploadprogress_get_info always return null. My uploadprogress config values uploadprogress support enabled Version 1.0.1 uploadprogress.file.contents_template /tmp/upload_contents_%s uploadprogress.file.filename_template /tmp/upt_%s.txt uploadprogress.get_contents 1 While googling around i found uploadprogress extension has some issue with Suhosin Patch < 0.9.26 but i am using Suhosin Patch 0.9.9.1

  • What's the simplest way to create a Zend_Form tabular display with each row having a radio button?

    - by RenderIn
    I've seen simple examples of rendering a Zend_Form using decorators, but I'm not sure they are able to handle the issue I'm facing very well. I query the database and get an array of user objects. I want to display these users as a form, with a radio button next to each of them and a submit button at the bottom of the page. Here's roughly what the form will look like: [user id] [email] [full name] ( ) 1 [email protected] Test user 1 (*) 2 [email protected] Test user 2 [SUBMIT] Is this something achievable in a reasonably straightforward way or do I need to use the ViewScript partial?

  • How can I expose an Objective-C function to JavaScript using WebKit on Mac OS X?

    - by Luke
    I understand to do this on the iPhone you need to trap link requests (as per my other iPhone question UIWebView Expose JavaScript) and you can easily do the reverse and access JavaScript from Obj-C code. However, I would like to have JavaScript be able to call some Objective-C functions that would somehow be registered with WebKit. I assume that you can do this better than trapping links like on the iPhone as on Mac OS X we have access to the full WebKit. I wish to basically do the reverse of Using JavaScript from Objective-C

  • How do I use XML Builder to create xml in rails?

    - by Angela
    I am trying the following, but the output XML is badly formed: def submit xml = Builder::XmlMarkup.new xml.instruct! xml.mail xml.documents xml.document xml.template xml.source "gallery" xml.name "Postcard: Image fill front" @xml_display = xml end I need it to look more like this: <?xml version="1.0" encoding="UTF-8"?> <mail> <documents> <document> <template> <source>gallery</source> <name>Postcard: Image fill front</name> </template> <sections> <section> <name>Text</name> <text>Hello, World!</text> </section> <section> <name>Image</name> <attachment>...attachment id...</attachment> </section> </sections> </document> </documents> <addressees> <addressee> <name>John Doe</name> <address>123 Main St</address> <city>Anytown</city> <state>AZ</state> <postal-code>10000</postal-code> </addressee> </addressees> </mail>

  • How can I create a finger scrollable Textbox in WM 6.5?

    - by Papajohn
    Hi everybody. I just noticed something weird in WM 6.5 emulators. Unlike 6.1 where finger panning kind of worked, the only way to scroll a Textbox appears to be through scrollbars. This behaviour is in contrast to what they have done for comboboxes: they are now gesture-friendly without the programmer's intervention. I.e. the user can select a choice from a standard drop down menu by panning and scrolling. Previously, you had to use the embedded scrollbar. The combobox's case implies that MS took some measures to provide standard gesture support for classic finger gestures, yet I cannot see something similar for textboxes. This makes me ask the following: Is there anything that can be done to make textboxes finger scrollabe easily? Note that I refer to managed .NET CF development. It is my understanding that in native development I could use the new Gestures API to achieve the scrolling effect. Yet, I am not sure if there is an easier and more straightforward method that I have missed.

  • How can I create a button with a UIActivityIndicator in my navigation bar with the same style as nor

    - by Jarin Udom
    All of the examples I've seen on here and other sites involved creating a UIActivityIndicatorView and loading it with something like: self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithCustomView:myActivityIndicatorView target:nil action:nil] autorelease]; However, that just creates a plain activity indicator in the navigation bar. What I want to do is have a button that looks just like the normal UIBarButtonSystemItem buttons but with an activity indicator instead of one of the default images. I've tried doing initWithImage and initWithTitle with nil images or titles and then adding the activity indicator as a subview, but that doesn't work. Any ideas?

  • How to do call function after client finishes download from tornado web server?

    - by Shabbyrobe
    I would like to be able to run some cleanup functions if and only if the client successfully completes the download of a file I'm serving using Tornado. I installed the firefox throttle tool and had it slow the connection down to dialup speed and installed this handler to generate a bunch of rubbish random text: class CrapHandler(BaseHandler): def get(self, token): crap = ''.join(random.choice(string.ascii_uppercase + string.digits) for x in range(100000)) self.write(crap) print "done" I get the following output from tornado immediately after making the request: done I 100524 19:45:45 web:772] 200 GET /123 (192.168.45.108) 195.10ms The client then plods along downloading for about 20 seconds. I expected that it would print "done" after the client was done. Also, if I do the following I get pretty much the same result: class CrapHandler(BaseHandler): @tornado.web.asynchronous def get(self, token): crap = ''.join(random.choice(string.ascii_uppercase + string.digits) for x in range(100000)) self.write(crap) self.finish() print "done" Am I missing something fundamental here? Can tornado even support what I'm trying to do? If not, is there an alternative that does?

  • What should a Java/SOA developer be able to do?

    - by Regular Joe
    I got assigned the task to list the activities a Java Developer should be able to perform and create an estimate about the time it would take. I've came up with the following: Create JDBC CRUD backend ( S=1d, M=5d, H=10d ) Create JSP/Servlet frontend for a CRUD app ( S=1d, M=10d, H=20d ) Create Swing desktop frontend ( S=1d, M=15d, H=30d) Create ORM based CRUD etc. Create Webapp fronend with webframework etc Where.. S = Small complexity M = Medium complexity H = High complexity 1d = 1 day This is thought for a Java "enterprise" developer. The other profile I have is SOA Developer, but I could not pass beyond: Create webservice ( S=.5d, M=2d, H=7d ) Q.- What other activities should a Java Developer be able to do? Q.- What activities should a SOA Developer be able to do? Please, help me with this, I know this is in the limit of the kind of questions that could be asked here, but I really need a little push on this, and I don't want to go to Yahoo Answers for this.

  • Cross-thread operation not valid: Control accessed from a thread other than the thread it was create

    - by SilverHorse
    I have a scenario. (Windows Forms, C#, .NET) There is a main form which hosts some user control. The user control does some heavy data operation, such that if I directly call the Usercontrol_Load method the UI become nonresponsive for the duration for load method execution. To overcome this I load data on different thread (trying to change existing code as little as I can) I used a background worker thread which will be loading the data and when done will notify the application that it has done its work. Now came a real problem. All the UI (main form and its child usercontrols) was created on the primary main thread. In the LOAD method of the usercontrol I'm fetching data based on the values of some control (like textbox) on userControl. The pseudocode would look like this: //CODE 1 UserContrl1_LOadDataMethod() { if(textbox1.text=="MyName") <<======this gives exception { //Load data corresponding to "MyName". //Populate a globale variable List<string> which will be binded to grid at some later stage. } } The Exception it gave was Cross-thread operation not valid: Control accessed from a thread other than the thread it was created on. To know more about this I did some googling and a suggestion came up like using the following code //CODE 2 UserContrl1_LOadDataMethod() { if(InvokeRequired) // Line #1 { this.Invoke(new MethodInvoker(UserContrl1_LOadDataMethod)); return; } if(textbox1.text=="MyName") //<<======Now it wont give exception** { //Load data correspondin to "MyName" //Populate a globale variable List<string> which will be binded to grid at some later stage } } BUT BUT BUT... it seems I'm back to square one. The Application again become nonresponsive. It seems to be due to the execution of line #1 if condition. The loading task is again done by the parent thread and not the third that I spawned. I don't know whether I perceived this right or wrong. I'm new to threading. How do I resolve this and also what is the effect of execution of Line#1 if block? The situation is this: I want to load data into a global variable based on the value of a control. I don't want to change the value of a control from the child thread. I'm not going to do it ever from a child thread. So only accessing the value so that the corresponding data can be fetched from the database.

  • How do I create something like a negated character class with a string instead of characters?

    - by Chas. Owens
    I am trying to write a tokenizer for Mustache in Perl. I can easily handle most of the tokens like this: #!/usr/bin/perl use strict; use warnings; my $comment = qr/ \G \{\{ ! (?<comment> .+? ) }} /xs; my $variable = qr/ \G \{\{ (?<variable> .+? ) }} /xs; my $text = qr/ \G (?<text> .+? ) (?= \{\{ | \z ) /xs; my $tokens = qr/ $comment | $variable | $text /x; my $s = do { local $/; <DATA> }; while ($s =~ /$tokens/g) { my ($type) = keys %+; (my $contents = $+{$type}) =~ s/\n/\\n/; print "type [$type] contents [$contents]\n"; } __DATA__ {{!this is a comment}} Hi {{name}}, I like {{thing}}. But I am running into trouble with the Set Delimiters directive: #!/usr/bin/perl use strict; use warnings; my $delimiters = qr/ \G \{\{ (?<start> .+? ) = [ ] = (?<end> .+?) }} /xs; my $comment = qr/ \G \{\{ ! (?<comment> .+? ) }} /xs; my $variable = qr/ \G \{\{ (?<variable> .+? ) }} /xs; my $text = qr/ \G (?<text> .+? ) (?= \{\{ | \z ) /xs; my $tokens = qr/ $comment | $delimiters | $variable | $text /x; my $s = do { local $/; <DATA> }; while ($s =~ /$tokens/g) { for my $type (keys %+) { (my $contents = $+{$type}) =~ s/\n/\\n/; print "type [$type] contents [$contents]\n"; } } __DATA__ {{!this is a comment}} Hi {{name}}, I like {{thing}}. {{(= =)}} If I change it to my $delimiters = qr/ \G \{\{ (?<start> [^{]+? ) = [ ] = (?<end> .+?) }} /xs; It works fine, but the point of the Set Delimiters directive is to change the delimiters, so the code will wind up looking like my $variable = qr/ \G $start (?<variable> .+? ) $end /xs; And it is perfectly valid to say {{{== ==}}} (i.e. change the delimiters to {= and =}). What I want, but maybe not what I need, is the ability to say something like (?:not starting string)+?. I figure I am just going to have to give up being clean about it and drop code into the regex to force it to match only what I want. I am trying to avoid that for four reasons: I don't think it is very clean. It is marked as experimental. I am not very familier with it (I think it comes down to (?{CODE}) and returning special values. I am hoping someone knows some other exotic feature that I am not familiar with that fits the situation better (e.g. (?(condition)yes-pattern|no-pattern)). Just to make things clear (I hope), I am trying to match a constant length starting delimiter followed by the shortest string that allows a match and does not contain the starting delimiter followed by a space followed by an equals sign followed by the shortest string that allows a match that ends with the ending delimiter.

  • How can I create a horizontal table in a single foreach loop in MVC?

    - by GenericTypeTea
    Is there any way, in ASP.Net MVC, to condense the following code to a single foreach loop? <table class="table"> <tr> <td> Name </td> <% foreach (var item in Model) { %> <td> <%= item.Name %> </td> <% } %> </tr> <tr> <td> Item </td> <% foreach (var item in Model) { %> <td> <%= item.Company %> </td> <% } %> </tr> </table> Where model is a simple object: public class SomeObject { public virtual Name {get;set;} public virtual Company {get;set;} } This would output a table as follows: Name | Bob | Sam | Bill | Steve | Company | Builder | Fireman | MS | Apple | I know I could probably use an extension method to write out each row, but is it possible to build all rows using a single iteration over the model? This is a follow on from this question as I'm unhappy with my accepted answer and cannot believe I've provided the best solution.
